Description
Technical Field
The invention relates to the technical field of glass sealing, in particular to an automatic control system and method for vacuum glass sealing.
Background
With the increasing increase of energy and environmental problems, novel energy-saving and environment-friendly materials become the focus of wide attention. The building energy consumption accounts for a large part of the whole urban energy consumption, and the door and window are the core of the building energy consumption, so that the key for reducing the heat transfer of the door and window is to reduce the energy consumption of the building. Energy-saving glass is in various types, and can be roughly divided into 3 types of hollow glass, coated glass and vacuum glass. The vacuum glass is a transparent and energy-saving green building material, integrates the technical advantages of coated glass and hollow glass, has superior performances in the aspects of heat preservation and insulation, dewing prevention, sound insulation, wind pressure resistance and the like, forms super energy-saving glass, is widely applied in multiple fields, and has very wide development prospect.
In the production and manufacturing of vacuum glass, a common production process comprises a process scheme of finishing vacuumizing and edge sealing operation in vacuum equipment at one time; sealing edges in the atmosphere, vacuumizing to detect leakage, heating to exhaust and sealing in the atmosphere, and the like. In these arrangements, the edge sealing operation is important because the vacuum glass is formed by combining two pieces of glass, and the edges must be sealed with a material. In the sealing process, if the solder is not sufficiently coated, high vacuum cannot be obtained subsequently, and the qualification rate of products is low; if the sealing path is distorted and the sealing is not uniform, the quality of the product is poor, so the uniformity and the sufficiency of the glass sealing are basic guarantee of the quality of the vacuum glass and need to be strictly controlled.
The edge sealing processing operation in the existing scheme is manually finished, the sealing reliability and the sealing efficiency of manual operation are relatively low, and the requirements of vacuum glass production and application which tend to be large-batch and high-quality at present can not be met.
Disclosure of Invention
The invention aims to provide a vacuum glass sealing automatic control system and a method, which are used for solving the technical problems of low efficiency and poor sealing effect of the existing manual sealing scheme.
In order to achieve the above purpose, the invention provides the following scheme:
the first scheme is as follows:
an automatic control system for vacuum glass sealing comprises a sealing table and a control box; the sealing-in platform comprises a glass bearing platform and a sealing-in mechanism; the glass bearing table is used for moving and positioning the glass piece; the sealing mechanism is used for sealing the glass piece; the control box comprises an automatic control module which is in communication connection with the glass bearing table and the sealing mechanism; the automatic control module is used for controlling the glass bearing table to move so as to position the glass piece and controlling the sealing mechanism to finish sealing of the corresponding glass piece.
The working principle and the advantages of the scheme are as follows: the automatic control module is arranged and used for controlling the glass bearing table to finish the movement and positioning work of the glass piece and controlling the sealing mechanism to finish the sealing work. Compare in conventional artifical sealing-in mode, this scheme replaces artifical work with automatic control module, all turn into digital automation with operations such as glass spare location, glass spare removal and control, the meticulous degree that the digit was controlled is higher, each step of operation can both be controlled by the accuracy, mechanical operation efficiency is compared in artifical sealing-in efficiency higher, can effectively solve current artifical sealing-in scheme inefficiency, the not good technical problem of sealing-in effect, reach higher sealing-in efficiency. And, because the controllability of digital operation is stronger, can guarantee that the sealing-in process is stable, reach higher sealing degree of consistency and full scale, sealing-in effect is better.
Further, the sealing mechanism comprises a welding gun and a position adjusting mechanism which are connected; the position adjusting mechanism comprises an X-axis transfer mechanism and a Y-axis transfer mechanism.
By the arrangement, the welding gun can move on an XY plane formed by an X axis and a Y axis, and can reach various positions on the XY plane to meet the processing requirements of glass pieces with different sizes.
Further, the automatic control module confirms a sealing path according to an automatic sealing strategy when controlling the sealing mechanism to finish sealing the corresponding glass piece; the automatic sealing strategy is to automatically generate sealing operation parameters of the sealing mechanism according to the parameters of the glass piece, and obtain a sealing path according to the sealing operation parameters; the parameters of the glass piece comprise the length, the width, the arc radius, the thickness and the thickness of a vacuum layer of the glass piece; the sealing operation parameters comprise X-axis speed, Y-axis speed, arc X-axis speed and arc Y-axis speed of the welding gun.
The sealing path is generated according to the parameters of the glass piece, and the sealing path and the glass piece can be perfectly matched by the arrangement, so that the sealing operation can be carried out on the glass piece body, and the sealing reliability is high. Meanwhile, the parameters of the glass piece also comprise the thickness of the glass piece and the thickness of a vacuum layer reserved on the glass piece, and different glass piece thicknesses and vacuum layer thicknesses have different requirements on the welding speed.
In addition, compared with the method that only the total thickness of the vacuum glass piece is considered in the existing scheme, the existing scheme only focuses on the area size of the sealed area, but does not further focus on the area sizes of different types of the sealed area, namely the area sizes of the vacuum layer and the glass layer, the sealing operation fineness is low, only the overall effect is focused on, and the production quality of the vacuum glass cannot be effectively improved.
In fact, different ratios of the area of the vacuum layer and the area of the glass layer in the sealing region may have different requirements for the sealing rate, for example, when the thickness of the vacuum layer is larger, that is, the area of the vacuum layer is larger, the vacuum layer needs more solder than the glass layer for filling, and accordingly, the sealing time of the vacuum layer is more, and the sealing rate should be correspondingly reduced to ensure sufficient sealing. When the thickness of the vacuum layer is small, namely the area of the glass layer is large, the sealing rate can be correspondingly increased, so that the welding flux is not excessively laminated while the sealing is ensured to be sufficient, and the processing quality of the vacuum glass is prevented from being influenced. The vacuum layer thickness and the glass layer thickness are respectively taken into consideration in the scheme, adaptive sealing operation parameters can be generated according to different proportion conditions of the vacuum layer area and the glass layer area in the sealing area, the fineness of sealing operation is higher, the processing effect on the sealing speed is better, and higher sealing processing quality can be achieved.
Further, the sealing operation parameters are dynamically adjusted according to different solder types.
The solder types are also brought into the confirmation basis of the sealing operation parameters, and the sealing operation parameters can be correspondingly adjusted according to different solder types, so that the various solders can exert respective optimal performances, and the sealing reliability is further improved. Compared with the method that the welding speed is not adjusted according to the type of the welding material but is judged according to whether the welding material completely covers the part to be welded or not in the existing scheme, the existing mode only focuses on the direct welding material coating effect, and the welding material in the mode can not be fused sufficiently to cause the sealing defect or the welding material performance is influenced excessively, so that the quality of the glass piece is influenced. The scheme does not have the problems, and the sealing operation is more targeted and more reliable.
Further, the glass bearing table comprises a frame, a sample bearing table and a transmission mechanism; the sample bearing table is arranged on the rack and used for bearing a glass piece, and a transmission mechanism is arranged between the sample bearing table and the rack; the transmission mechanism is a roller and is used for driving the sample bearing table to move relative to the plane of the rack.
By adopting the structure, the roller and the sample bearing platform bear and transmit the glass piece, the structure is simple, and the transmission is stable.
Furthermore, the glass bearing table also comprises a limiting mechanism; the limiting mechanism is fixedly arranged on the rack; the limiting mechanism comprises an X-direction limiting mechanism and a Y-direction limiting mechanism, wherein the X-direction limiting mechanism is evenly arranged along the X axial direction of the rack, and the Y-direction limiting mechanism is evenly arranged along the Y axial direction of the rack.
The limiting mechanism is used for accurately limiting the movable distance of the glass piece, so that the glass piece can be prevented from moving too much and can be conveniently positioned.
Furthermore, a glass sensor is also arranged on the frame; the glass sensor is arranged at the intersection of the X-direction limiting mechanism and the Y-direction limiting mechanism.
Locate stop gear's intersect department with glass sensor, glass sensor can respond to whether the glass spare reaches stop gear department, can further confirm the position state of glass spare accurately, and the degree of accuracy of location is higher.
Further, the control box also comprises a reset module; the reset module is in communication connection with the automatic control module; the reset module is used for resetting the glass bearing table and the sealing mechanism.

The frame 4 is also provided with a glass sensor 8; the glass sensor 8 is mounted at the intersection of the X-direction stopper mechanism 71 and the Y-direction stopper mechanism 72. Specifically, the glass sensor 8 is also in communication connection with the automatic control module, and when the glass piece reaches the limiting mechanism, the glass sensor 8 can transmit signals in time to provide reference for the action arrangement of the sealing mechanism.
The sealing mechanism comprises a welding gun 3 and a position adjusting mechanism which are connected; the position adjustment mechanism includes an X-axis transfer mechanism 31 and a Y-axis transfer mechanism 32. Specifically, gantry guide rails are symmetrically arranged on the upper surface of the frame 4 along the Y direction, the Y-axis transfer mechanism 32 is connected with the gantry guide rails in a sliding manner, the X-axis transfer mechanism 31 is connected with the Y-axis transfer mechanism 32 in a sliding manner, and the welding gun 3 is fixedly arranged on the X-axis transfer mechanism 31.

For example: aiming at a certain glass piece, the glass piece parameters comprise 700mm of length, 400mm of width, 5mm of thickness, 5mm of arc radius and 0.5mm of vacuum layer thickness of the glass piece; the adopted solder is tin-lead-silver solder; the corresponding automatically generated sealing operation parameters are sealing temperature 690 ℃, X-axis speed 10mm/s, Y-axis speed 10mm/s, circular arc X-axis speed 7mm/s, circular arc Y-axis speed 7mm/s and the like, wherein the sealing speed at the circular arc is slightly slower than that at the straight edge, and the speed is slightly reduced to ensure the sealing sufficiency at the circular arc because the sealing path at the circular arc is more complicated than that at the straight edge. In addition, for another glass piece, the parameters of the glass piece are the same as those of the glass piece except for the thickness of the vacuum layer, and the thickness of the vacuum layer of the glass piece is 0.2 mm; the solder used is also tin-lead-silver solder.

Then, sealing a second long edge of the glass piece along the X-axis negative direction; after the second long edge of the glass piece is sealed, the X-axis transfer mechanism 31 and the Y-axis transfer mechanism 32 control the welding gun 3 to finish the sealing of the glass corner arc; sealing the second short side of the glass piece along the Y-axis negative direction; and after the sealing of the short edge 2 of the glass is finished, automatically closing the welding gun 3.

The system supports manual input operation, customized sealing operation can be achieved through setting of all parameters, and the system is higher in safety degree of operation due to the fact that the authority setting function and the alarm module are arranged.
Example three:
an automatic control system for vacuum glass sealing is additionally provided with a scanning mechanism and an error correction module on the basis of the second embodiment. The scanning mechanism is fixed on the rack 4 and used for scanning and confirming parameters of the glass piece. The scanning mechanism is in communication connection with the automatic control module, and the scanning mechanism directly transmits the glass piece parameter information to the automatic control module after scanning to confirm the sealing operation parameters by the automatic control module.
The error correction module is arranged in the control box 2, the error correction module and the automatic control module are also in communication connection, and the error correction module is used for verifying the correctness and the matching of parameters of the glass piece and sealing operation parameters; the error correction module is pre-stored with a standard requirement library corresponding to the vacuum glass, and in this embodiment, the standard requirement library is set according to the standard of "GB/T38586-. The error correction module also stores limit parameter values of glass pieces which can be sealed and connected by the system, and in the embodiment, the limit parameter values include a minimum length and width value of 300mmX300mm, a maximum length and width value of 1500mmX2000mm, a minimum thickness of 3mm, a maximum thickness of 12mm and the like.
When the scanning mechanism is faulty or the manual parameters are input incorrectly, for example: when the thickness of the vacuum layer is larger than the total thickness of the glass piece, the total thickness of the vacuum layer and the glass piece is smaller than the minimum processing thickness or larger than the maximum processing thickness, the length or the width of the glass piece is larger than the maximum processing length and width value or smaller than the minimum processing length and width value, and the like, the error correction module controls the scanning mechanism to execute repeated scanning, if the repeated scanning result still has errors, the error correction module controls the scanning mechanism to set related parameters as limit values, for example, the length and the width value of the glass piece exceeding the maximum processing length and width value is changed into the maximum processing length and width value, and the automatic control module suspends the sealing process and communicates with the alarm module to inform a worker to execute further processing. When the automatic control module handles data errors, for example: when the sealing rate is higher than the maximum sealing rate which can be realized by the system or the sealing rate is not matched with the parameter value of the glass piece, the error correction module controls and calculates the sealing rate and transmits the sealing rate value.
The present embodiment further provides an automatic control method for vacuum glass sealing, which is the same as the method in the first embodiment, and therefore is not repeated herein.
Compared with the second embodiment, the automatic control system and the method for vacuum glass sealing provided by the embodiment have the advantages of higher automation degree and higher reliability in system operation. The setting of the scanning mechanism saves the conventional glass piece parameter confirmation process which needs manual pre-completion, the system mechanism automatically confirms the glass piece parameters, and compared with manual confirmation input, the reliability of parameter confirmation is higher, the manual input error can be effectively saved, and the possible manual input error can be avoided. The error correction module is beneficial to timely coping with parameter input or parameter calculation matching errors which may occur in the system, and the reliability of the system operation is stronger.
