Detailed Description

The application will now be described in further detail with reference to specific examples thereof in connection with the accompanying drawings.

It should be noted that, the terms "upper", "lower", "left", "right", and the like in the embodiments of the present application are described in terms of the angles shown in the drawings, and should not be construed as limiting the embodiments of the present application. In the context of this document, it will also be understood that when an element is referred to as being "on" or "under" another element, it can be directly on the other element or be indirectly on the other element through intervening elements.

Furthermore, reference herein to "a plurality" means at least two in number.

As shown in fig. 1, the present application provides a battery baking apparatus 1, which baking apparatus 1 heats a battery in a heat transfer and heat radiation manner to reduce the water content of a pole piece in the battery.

Specifically, the baking apparatus 1 includes a baking base 10, a plurality of heating plates 20, and a plurality of partitions 30. Wherein the baking base 10 is used as a supporting carrier and is provided with a containing space for containing a battery; the heating plate 20 is used as a heating source for baking the battery, and can release heat; the partitioning member 30 and the heating plate 20 are disposed to intersect to partition the receiving space into a plurality of independent subspaces.

In an alternative embodiment, as shown in fig. 1, the baking base 10 may include a bottom plate 100 and a pair of side plates 102 disposed on the bottom plate 100, where the pair of side plates 102 are disposed on opposite sides of the bottom plate 100, and the three together define the accommodating space. It should be understood that the particular embodiment of the bake station 10 is not so limited and that other alternatives are possible.

Each heating plate 20 and each partition 30 are arranged on the baking base 10 at intervals, and the arrangement direction of the heating plates 20 and the arrangement direction of the partition 30 are crossed, so that the accommodating space is divided into a plurality of latticed subspaces by the criss-cross heating plates 20 and the partition 30, and at least one battery can be placed in each subspace in the baking process.

The crossing manner of the heating plate 20 and the separator 30 may be vertical crossing or inclined crossing, which is not limited herein, and may be provided according to the external shape of the battery by those skilled in the art.

In the present application, in order to improve the compatibility of the battery baking device 1 and enable the battery baking device to meet the baking requirements of batteries with different external dimensions, at least one heating plate 20 and at least one partition member 30 can be arranged to move relative to the baking base 10, that is, the volume of the subspace can be increased and decreased by the heating plate 20 and the partition member 30 which are movably arranged, so that the battery baking device 1 can be used for baking batteries with different dimensions to improve the compatibility of battery changing.

In an alternative embodiment, each heating plate 20 and each partition 30 may be movably disposed on the baking base 10, so that each subspace may be correspondingly increased or decreased according to the external dimensions of the battery, to further improve the compatibility of the battery baking apparatus 1.

The number of the heating plates 20 and the spacers 30 is not limited to a plurality, and may be one, and when the heating plates 20 are provided in one, the "at least one heating plate 20" and the "at least one spacer 30" refer to the heating plates 20 and the spacers 30.

With continued reference to fig. 1, each of the spacers 30 is disposed on the bottom plate 100 and arranged in a transverse direction (X direction in fig. 1) on the bottom plate 100, each of the heating plates 20 is disposed above the spacers 30, and two ends of each of the heating plates 20 are respectively connected to a pair of side plates 102 and arranged in a longitudinal direction (Y direction in fig. 1), so that the arrangement direction of each of the heating plates 20 is perpendicular to the arrangement direction of each of the spacers 30.

Further, in order to improve the baking efficiency, the bottom plate 100 may be also set as a heating source for baking the battery, so that the bottom plate 100 and the heating plate 20 may release heat together, and bake from the side and bottom surfaces of the battery respectively, so that more heat may be transferred to the battery, thereby improving the baking rate and shortening the baking time.

The bottom plate 100 and the heating plate 20 as the heat generating sources may be formed of an aluminum housing structure, in which a heat generating pipe is provided, and the heat generating pipe is energized to generate heat.

In one embodiment, as shown in fig. 2, the movably disposed heating plate 20 may be slidably coupled to the baking base 10 by a sliding fit, for example, the heating plate 20 is slidably coupled to the side plate 102. Specifically, the upper end surface of the side plate 102 is provided with a groove 1020, and the heating plate 20 is slidably matched with the groove 1020.

After the heating plate 20 is adjusted to a proper position, the heating plate 20 is also fixed at the position to avoid the collision of the battery with the heating plate 20 in the Y direction. For this purpose, the battery baking apparatus 1 further includes a heating plate locking mechanism 40 connected to the heating plate 20 movably provided, and at any position of the groove portion 1020, the heating plate locking mechanism 40 can lock the heating plate 20 at that position, and the lock position can be defined as a first lock position of the baking base 10.

It is easy to understand that the heating plate 20 is a heat generating source, and its own temperature is high, so it is inconvenient to directly fix the heating plate 20 having a high temperature.

To overcome this disadvantage, in one specific embodiment, the heating plate locking mechanism 40 may be provided in two parts, i.e., a connecting part 400 and a locking part 402 connected, wherein the connecting part 400 is connected to the heating plate 20, and the locking part 402 serves to lock the heating plate 20 at any position of the groove part 1020. After the arrangement, the heating plate locking mechanism 40 can be matched with the groove part 1020 so as to realize the relative movement of the heating plate 20 and the side plate 102, and can also fix the heating plate 20 and the groove part 1020 so as to realize the relative fixation of the heating plate 20 and the side plate 102.

In the present embodiment, the connection part 400 is provided as a slider that is engaged with the groove part 1020, and the locking part 402 is provided as a bolt, but is not limited thereto.

For the scheme that the heating plates 20 are movably arranged, each heating plate 20 can be connected with the heating plate locking mechanism 40, further, the heating plate locking mechanism 40 can be connected with both ends of each heating plate 20, that is, the upper end face of the other side plate 102 is also arranged to be of the same structure as the groove part 1020, so that smoothness of sliding fit of the heating plates 20 and the side plates 102 can be ensured, and fixing reliability of the heating plates 20 and the side plates 102 can be ensured.

However, it should be noted that the manner in which the heating plate 20 is movably disposed with respect to the baking base 10 is not limited to the sliding connection, but may be alternatively provided, such as a rolling connection, etc., and the heating plate locking mechanism 40 may be modified according to the actual selection scheme.

Further, as shown in fig. 3, in order to ensure that the heating plate 20 can be reliably fixed at the first locking position, the baking apparatus 1 further includes a stopper 50, the stopper 50 is disposed on the partition 30, and the stopper 50 can be slidably connected to the partition 30. When the heating plate 20 is movable, the limiting block 50 can correspondingly move on the partition member 30, and when the heating plate 20 is fixed on the side plate 102, the limiting block 50 can be correspondingly fixed on the partition member 30, so that the limiting fit of the heating plate 20 and the limiting block 50 in the moving direction (see Y direction in fig. 2) of the heating plate 20 is realized, and the reliability of the fixing of the heating plate 20 is further improved.

As shown in fig. 4, the stopper 50 includes a stopper portion 500 and a recess portion 502, and the heating plate 20 is embedded in the recess portion 502, at this time, the stopper portion 500 is located at one side of the heating plate 20, and when the heating plate 20 moves relative to the baking base 10, the stopper 50 moves along with the heating plate 20, and when the heating plate 20 moves to a proper position, is locked by the locking portion 402. Meanwhile, the stopper portion 500 is provided with a hole 5000 through which the fastener passes, and the stopper portion 500 may be fixed to the separator 30 by the fastener. At this time, the heating plate 20 is restrained by the stopper 50.

The limiting portions 500 may be provided at both sides of the recess 502, respectively, so that, on one hand, the position of the heating plate 20 may be more reliably limited, and, on the other hand, one of the limiting portions 500 may be selectively fixed according to the moving direction of the heating plate 20. Of course, in practical applications, it is more reliable to fix two limit portions 500 at the same time.

The number of the stoppers 50 may be set to be plural according to the length of the heating plate 20, so that at each preset distance, one stopper 50 is in a stopper fit with the heating plate 20, thereby reducing the deformation of the heating plate 20 locally to ensure effective heat transfer or heat radiation with the battery.

It is easy to understand that the arrangement of the separator 30 can realize the limitation of the length direction (X direction in fig. 2) of the battery on one hand, and can also be used for locking the limiting block 50 on the other hand, so that after each heating plate 20 can be adjusted to a corresponding position according to the thickness of the battery, the limiting block 50 is locked and fixed with the separator 30, thereby limiting each heating plate 20 in a proper position.

When the limiting block 50 is locked and attached to the partition 30, the subspace for accommodating the battery has a predetermined size, and each independent subspace can be regarded as being surrounded by the limiting block 50 and the heating plate 20. To avoid rigid contact between the battery and the stopper 50 during the taking and placing process, the stopper 50 may be made of a flexible material, such as rubber, and the stopper 50 is located closer to the battery than the separator 30.

As shown in fig. 5, in an alternative embodiment, a fixing portion may be further provided on the side plate 102, and the movably provided heating plate 20 may be further fixed at a predetermined position by the fixing portion, where the fixing portion may perform an auxiliary fixing function, and together with the heating plate locking mechanism 40, the fixing of the heating plate 20 may be performed.

In the embodiment shown in fig. 5, the fixing portion may be implemented as a locking groove 1022, the locking groove 1022 extending in the arrangement direction of the heating plates 20, and the fastener locking each heating plate to the side plate 102 via the locking groove 1022.

In this embodiment, the locking grooves 1022 are provided with a plurality of groups, and each group of locking grooves 1022 is disposed in parallel, wherein adjacent portions of the heating plate 20 may share the same group of locking grooves 1022, so as to avoid the overlong opening of the locking grooves 1022, which would impair the strength of the side plate 102.

In addition, each set of locking grooves 1022 may include at least two sub-locking grooves 1022a, so that for one heating plate 20, it may be simultaneously locked with the two sub-locking grooves 1022a, further enhancing the stability of the heating plate 20 after being fixed.

As is known from the foregoing, the partition 30 is also movably disposed on the baking base 10, and the partition 30 and the baking base 10 may be connected by sliding connection, for example, a sliding rail 1000 may be disposed on the bottom plate 100 at a position corresponding to two ends of the partition 30, and the partition 30 is slidably engaged with the sliding rail 1000, but not limited thereto.

Referring again to fig. 1, the battery baking apparatus 1 further includes a spacer locking mechanism 60, and the spacer locking mechanism 60 can fix the spacer 30 to the baking base 10 to ensure that the spacer does not interfere with the battery in the X direction. This position may be defined as a second locked position of the baking base 10.

The toaster base 10 may have a plurality of second locking positions, that is, the divider 30 may be locked at any one of the second locking positions of the toaster base 10 by the divider locking mechanism 60, so that the size of the subspace may be adjusted.

In one embodiment, the partition 30 may be provided with a locking hole 300, and the partition locking mechanism 60 may be correspondingly provided with a bolt, and the bolt may be connected with the slide rail 1000 through the locking hole 300, so that the partition 30 may be locked and fixed on the baking base 10.

Of course, the spacer locking mechanism 60 is not limited to the above-described solution, and one skilled in the art may make a selection according to circumstances.

As is known, the spacer 30 can be moved from one of the second locking positions to the other second locking position, and in order to facilitate the movement of the spacer 30, the spacer 30 can be moved from one of the second locking positions to the other second locking position in a sliding fit manner by means of the sliding fit of the spacer 30 with the slide rail 1000, so that the position adjustment of the spacer 30 can be more convenient and faster.

After the separator 30 is locked, a gap may be left between the battery and the separator 30 (also referred to as the battery and the stopper 50) to facilitate the battery to be grasped by the manipulator.

It should be noted that, the heating plate 20 located at the middle position may be fixed relative to the baking base, and the rest of the heating plates 20 may be movable relative to the heating plate 20 that is fixed, so as to increase or decrease the volume of the subspace.

The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
