The functions include insulation, cushioning, wear-resistant, sealing, and appearance decoration. In a common lithium ion battery, a battery core of the battery consists of three major parts, namely a positive electrode material, a negative electrode material, an electrolyte and a diaphragm, the battery core cannot be directly used, and a soft aluminum plastic film or a material such as aluminum and steel can be used as a packaging shell. However, the battery core itself is very fragile, and is often scratched and crushed by the casing or contaminated by the electrolyte during the manufacturing process, and besides, the metal casing can also make the battery core easily short-circuited, so a Mylar film needs to be attached to the surface of the battery core after top sealing to protect the battery core.

Although the structure of the mode can meet the production requirement, the three manipulators are adopted, so that the whole structure is complex, and the occupied space is large.

Based on the above, the invention provides the combination device of the battery cell packaging material and the battery cell packaging equipment, which can simplify the whole structure of the equipment, thereby reducing the occupied space of the equipment.

The following describes in detail the combination device of the cell packaging material and the cell packaging apparatus by specific embodiments:

example one

The application provides a composite set of electricity core packaging material, as shown in fig. 2, including material loading module 1, stack module 2 and get material module 3. The feeding module 1 and the stacking module 2 are respectively arranged at two sides of the material taking module 3, and the positions of the material taking station 5, the stacking station 6 and the hot melting station 7 are shown in fig. 2. The feeding module 1 comprises a bottom support material storing table 11, a Mylar material storing table 12 and a first displacement mechanism 13 for driving the Mylar material storing table 12 and the bottom support material storing table 11 to move alternately to the material taking station 5; the stacking module 2 comprises a first stacking table 21 and the first stacking table 21 is located at the stacking station 6, and the material taking module 3 can pick up and move materials on the material taking station 5 to the stacking station 6. Because the material platform 11 and the Mylar material platform 12 can get into the material taking station 5 in turn, the material taking module 3 only needs to convey materials between the material taking station 5 and the superposition station 6, the moving route is single, and the material taking can be completed by adopting a set of mechanical conveying device, so that the whole structure of the equipment is simplified, and the occupied space of the equipment is reduced.

In a first embodiment, the first superimposing table 21 is fixedly mounted on the ground at the superimposing station 6.

The specific working process of the cell packaging material combination device at this time is as follows:

in the initial state, the bottom support material storage table 11 is located at the material taking station 5. The material taking module 3 picks up the bottom support on the bottom support material storing platform 11 and conveys the bottom support to the superposition station 6, in the process that the material taking module 3 conveys the bottom support, the bottom support material storing platform 11 is moved away from the material taking station 5 under the driving of the first displacement mechanism 13, and the Mylar material storing platform 12 is moved to the material taking station 5. The material taking module 3 is used for placing the bottom support on the first superposition table 21 and then conveying the Mylar on the Mylar storage table 12 to the first superposition table 21 to be superposed with the bottom support. After the superposition is completed, the bottom support Mylar component is removed, the first superposition table 21 is empty, and the next superposition can be carried out. The fixed installation of first stack platform can reduce the motion subassembly, reduces the fault incidence.

In another implementation manner, as shown in fig. 2, the stacking module 2 further includes a second stacking table 22 and a second displacement mechanism 23 for driving the first stacking table 21 and the second stacking table 22 to move alternately between the stacking station 6 and the heat-fusing station 7; the material taking module 3 can pick up and move the material on the material taking station 5 to the stacking station 6.

The specific working process of the combined device of the battery cell packaging material is as follows:

in the initial state, the bottom tray material storage table 11 is located at the material taking station 5, and the first stacking table 21 is located at the stacking station 6. The material taking module 3 picks up the bottom support on the bottom support material storing platform 11 and conveys the bottom support to the superposition station 6, in the process that the material taking module 3 conveys the bottom support, the bottom support material storing platform 11 is moved away from the material taking station 5 under the driving of the first displacement mechanism 13, and the Mylar material storing platform 12 is moved to the material taking station 5. The material taking module 3 is used for placing the bottom support on the first superposition table 21 and then conveying the Mylar on the Mylar storage table 12 to the first superposition table 21 to be superposed with the bottom support. After the stacking is completed, the first stacking table 21 and the second stacking table 22 move alternately under the driving of the second displacement mechanism 23, the first stacking table 21 moves to the hot melting station 7 to perform hot melting on the stacked bottom supports and Mylar components, and the second stacking table 22 moves to the stacking station 6 to stack a next group of bottom supports and Mylar components. Therefore, the second displacement mechanism 23 can respectively drive the first stacking table 21 and the second stacking table 22 to alternately move between the stacking station 6 and the hot melting station 7, so that after one stacking operation is completed, the next stacking operation is performed without waiting for the completion of the hot melting operation and after the stacking table is empty, the overall structure can continuously take materials and stack, and the operation efficiency of the equipment is improved.

Specifically, the material taking module 3 capable of realizing the functions can have the following structure:

as shown in fig. 3, the material taking module 3 includes a rotating shaft 31, a rotating motor 32 and a rotating arm 33. The rotating shaft 31 is vertically arranged and fixedly installed on the ground; the middle part of the rotating arm 33 is rotatably connected with the rotating shaft 31, the two ends of the rotating arm 33 are respectively provided with a first picking part 331 and a second picking part 332, and the first picking part 331 and the second picking part 332 are symmetrically arranged relative to the rotating shaft 31; the rotating motor 32 can drive the rotating arm 33 to horizontally rotate around the rotating shaft 31; according to the structure, when the first picking part 331 is located at the material taking station 5, the second picking part 332 is located at the stacking station 6, the first picking part 331 can pick up materials, and then when the first picking part 331 rotates 180 degrees to place materials at the stacking station 6, the second picking part 332 rotates to the material taking station 5 to pick up materials, so that in the continuous rotating material loading stacking process, two picking parts can pick up or place after rotating 180 degrees every time.

The material taking module 3 with such a structure can complete the operation of the first picking part 331 and the second picking part 332 only by one drive.

It should supplement and explain that above-mentioned material module 3 can be for elevation structure, realizes that concrete elevation structure's mode as follows:

in the first implementation manner, the rotating shaft 31 is an electric telescopic rod, and the electric telescopic rod is a mechanism that drives a bearing to push a trapezoidal thread screw rod to move by utilizing the rotation of a motor through the cooperation between gears. When the material stacking height on the Mylar material storage table 12 or the bottom support material storage table 11 changes, the first picking part 331 and the second picking part 332 which can just pick up the material before can not directly pick up the material now, at this time, the electric telescopic rod can adjust the length to drive the first picking part 331 and the second picking part 332 on the whole rotating arm 33 and the rotating arm 33 to move up and down, so as to adapt to the material stacking height change on the Mylar material storage table 12 or the bottom support material storage table 11, the up-down adjusting range of the lifting structure is larger, and the lifting structure is more adaptable to more situations.

In a second implementation manner, telescopic cylinders are respectively installed between the first picking part 331 and the second picking part 332 and the rotating arm 33, the two telescopic cylinders can respectively control the heights of the first picking part 331 and the second picking part 332, when the first picking part 331 and the second picking part 332 perform material taking and stacking work, the heights of the first picking part 331 and the second picking part 332 can be respectively adjusted through the two telescopic cylinders according to the heights of the Mylar material storage table 12 or the bottom support material storage table 11 and the first stacking table 21 or the second stacking table 22, and the heights of the first picking part 331 and the second picking part 332 can be respectively adjusted according to the different positions of the first picking part 331 and the second picking part 332, so that the work is more convenient.

The first guide rail 341 and the second guide rail 342 are parallel to each other and are fixed on the top of the support member 37, one end of each of the first guide rail 341 and the second guide rail 342 is located at the material taking station 5, the other end of each of the first guide rail 341 and the second guide rail 342 is located at the stacking station 6, the third picking part 361 is connected onto the first guide rail 341 in a sliding manner, the fourth picking part 362 is connected onto the second guide rail 342 in a sliding manner, the first linear driving device 351 is used for driving the third picking part 361 to slide along the first guide rail 341, and the second linear driving device 352 is used for driving the fourth picking part 362 to slide along the second guide rail 342. The first linear driving device 351 and the second linear driving device 352 can be, but are not limited to, lead screw nuts or linear motors. Here, it should be noted that the first linear driving device 351 and the second linear driving device 352 are installed to ensure that the third pickup portion 361 and the fourth pickup portion 362 do not interfere with each other in the movement. The overlapping modules 2 at the two ends of the material taking module 3 in the structure are not restricted from the arrangement positions of the material feeding module 1, and the overlapping and material taking can be carried out as long as the overlapping and the material taking are not influenced. And the third pick-up 361 and the fourth pick-up 362 can operate independently without requiring synchronization of the pick-up action and the placing action. The device requires less space when in operation.

in the first implementation, the supporting members 37 at the two ends are electric telescopic rods, and the electric telescopic rods are a mechanism for driving the bearings to push the trapezoidal thread screw rod to move by utilizing the rotation of the motor through the cooperation between the gears. When the material stacking height of the Mylar material storage table 12 or the bottom support material storage table 11 changes, the third pickup part 361 and the fourth pickup part 362 which can smoothly pick up the materials can not directly pick up the materials before, at this time, the electric telescopic rod piece can adjust the heights of the third pickup part 361 and the fourth pickup part 362 on the whole guide rail 34 and the guide rail 34 by adjusting the length of the supporting piece 37 so as to adapt to the material stacking height change of the Mylar material storage table 12 or the bottom support material storage table 11, and the up-down adjusting range of the lifting structure is large and is more adaptable to more conditions.

In a second implementation manner, telescopic cylinders are respectively installed between the third pickup portion 361 and the first guide rail 341 and between the fourth pickup portion 362 and the second guide rail 342, the two telescopic cylinders can respectively control the heights of the third pickup portion 361 and the fourth pickup portion 362, when the third pickup portion 361 and the fourth pickup portion 362 take materials and perform stacking work, the heights of the third pickup portion 361 and the fourth pickup portion 362 can be respectively adjusted through the two telescopic cylinders according to the heights of the Mylar material storage table 12 or the bottom material storage table 11 and the first stacking table 21 or the second stacking table 22, and the lifting manner can respectively adjust the heights of the third pickup portion 361 and the fourth pickup portion 362 according to the difference of the positions of the third pickup portion 361 and the fourth pickup portion 362, so that the work is more convenient.

In particular, the pickup portion of the present embodiment can have various implementations, and in one possible implementation, the pickup portion can be implemented by using a suction cup. When specifically setting up, can set up the adsorption plane of sucking disc downwards, the sucking disc can utilize the outside pressure differential of sucking disc chamber and sucking disc to fix the material in the sucking disc below, because Mylar is the sheet material, easy adhesion, broken and the quality is lighter. And pick up the power comparatively uniformly when chooseing for use the sucking disc to pick up, can reduce the loss in picking up, and realize the monolithic more easily and pick up.

Specifically, the used suction cup can be an extrusion type suction cup, namely, air in the suction cup is extruded by downward extrusion force, so that negative pressure is generated in the suction cup, and suction force is formed to suck an object. The extrusion type sucker does not need a power source and has the advantages of simple structure, no noise and the like.

The sucking disc can also be a vacuum pump exhaust type sucking disc, the sucking disc utilizes an electromagnetic control valve to connect the vacuum pump with a sucking disc cavity of the sucking disc, when the vacuum pump exhausts, air in the sucking disc cavity is pumped away, the sucking disc cavity forms negative pressure to suck objects, and materials are picked up. When the material is placed, the electromagnetic control valve can communicate the suction disc cavity with the atmosphere, and the suction disc can lose suction force to loosen the material. The vacuum pump exhaust type sucker has larger suction force and is more stable when absorbing materials.

In another possible implementation mode, the picking part can also be a mechanical claw, the mechanical claw is driven by a motor to grab the material by fingers or a clamp, the mechanical claw driven by the motor has flexible working mode and compact integral structure, and the clamping force and the opening amplitude of the fingers or the clamp can be precisely controlled.

The second displacement 23 mechanism that enables the first superimposing table 21 and the second superimposing table 22 to be indexed can be implemented in various ways. For example, in the structure shown in fig. 5, the second displacement mechanism 23 includes a lifting device 231, an upper rail 232, a lower rail 233, a first driving device 234, and a second driving device 235. The upper guide rail 232 and the lower guide rail 233 are arranged in parallel, the first stacking table 21 is connected with the upper guide rail 232 in a sliding mode, the second stacking table 22 is connected with the lifting device 231, the lifting device 231 is connected with the lower guide rail 233 in a sliding mode, and the lifting device 231 is used for driving the second stacking table 22 to lift. The stacking station 6 is positioned at one end of the upper guide rail 232, and the hot melting station 7 is positioned at the other end of the upper guide rail 232; the first driving device 234 is used for driving the first stacking table 21 to slide along the upper guide rail 232, and the second driving device 235 is used for driving the second stacking table 22 to slide along the lower guide rail 233.

The process of exchanging positions between the first superimposing stage 21 and the second superimposing stage 22 is as follows: initially, when the first stacking station 21 moves along the upper guide rail 232 to the stacking station 6, the empty second stacking station 22 is adjusted to a lowered state and moves along the lower guide rail 233 to below the heat-fusing station 7, as shown in fig. 6 a. After the first stacking station 21 completes the corresponding process at the stacking station 6, the first stacking station 21 moves to the heat-fusing station 7 along the upper guide rail 232. During the movement of the first stacking table 21, the second stacking table 22 moves along the lower guide rail 233 to below the stacking station 6, as shown in fig. 6b, and then the second stacking table 22 enters the stacking station 6 by being lifted by the lifting device 231, as shown in fig. 6 c. After the stacking station 6 and the hot melting station 7 complete the corresponding processes, the materials on the first stacking station are taken away.

In another implementation, as shown in fig. 7, the first displacement mechanism 13 may further include a rotary disc 236, a rotary shaft 237, and a rotary motor 238.

The lifting device 131 is directly and fixedly arranged on the ground below the material taking station 5, and other components and the installation mode are kept unchanged. The process that the Mylar material storing platform 12 and the bottom support material storing platform 11 alternately move to the material taking station 5 is as follows: when the bottom pallet stocker 11 enters the pickup station 5 along the upper rail 132, the Mylar stocker 12 is lowered as shown in fig. 10 a. After the material taking process is completed, the bottom supporting material storing table 11 leaves the material taking station 5 along the upper guide rail 132, and at this time, the Mylar material storing table 12 enters the material taking station 5 under the jacking of the lifting device 131, as shown in fig. 10 b. And then, after the Mylar material storing platform 12 finishes the material taking process, the Mylar material storing platform descends and leaves the material taking station 5, so that the bottom support material storing platform 11 can conveniently enter the material taking station 5 again. By this reciprocating movement, the Mylar material storage table 12 and the bottom support material storage table 11 can be alternately moved to the material taking station 5. This displacement mechanism reduces the stroke of the Mylar storage table 12 while reducing the components required for linear motion of the Mylar storage table 12.

After arbitrary stack module moved to hot melt station 7, hot melt module 4 can descend and carry out hot melt processing to the material at the stack bench, and the material after the hot melt can be taken away and get into other processes.

When carrying out the hot melt, hot melt module 4 adopts the electricity mode of generating heat, makes the strip that generates heat become hot and contact the material, and whole hot melt process is ended after lasting 2 ~ 3 seconds. The hot melting process can be rapidly completed without influencing the efficiency of the superposition process by arranging the hot melting module 4, so that the comprehensive efficiency of the combined device is higher.
