Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0041] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present utility model. Therefore, the "in one embodiment" or "in an embodiment" that appears throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics can be combined in one or more embodiments in any suitable manner.

[0042] As Figures 1 to 6 shown, this adjustment device is used to adjust the position of the circuit board 2 of the hot-pressing forming fixture. A plurality of hot-pressing forming plates 1 are arranged in parallel at intervals in the inner cavity of the hot-pressing forming fixture. Two end portions of the hot-pressing forming plate 1 are respectively provided with a circuit board 2. The adjustment device includes:

[0043] A first frame 3 and a second frame 4 spaced apart along a first direction (X), and the first frame 3 and the second frame 4 are respectively used for connecting a circuit board 2.

[0044] A horizontal adjustment assembly 5, the first frame 3 and the second frame 4 are movably connected by the horizontal adjustment assembly 5, so that the first frame 3 and the second frame 4 approach or move away from each other along the first direction (X).

[0045] A vertical adjustment assembly 6, the vertical adjustment assembly 6 is movably connected to at least one of the first frame 3 and the second frame 4, and the vertical adjustment assembly 6 moves along a second direction (Z), wherein the first direction (X) and the second direction (Z) are two intersecting directions.

[0046] A circuit board 2 is respectively connected to the first frame 3 and the second frame 4, and at least one of the first frame 3 and the second frame 4 moves along the second direction Z with the vertical adjustment assembly 6 to change the dimension of at least one of the first frame 3 and the second frame 4 in the second direction (Z).

[0047] As can be seen from the above embodiments, in the embodiments of the present utility model, since the adjusting device includes a first frame 3 and a second frame 4 arranged at intervals along the first direction (X), the first frame 3 and the second frame 4 are respectively used to connect the circuit boards 2, and the first frame 3 and the second frame 4 are movably connected by a horizontal adjusting component 5, so that the first frame 3 and the second frame 4 approach or move away from each other along the first direction (X). Therefore, the distance between the two circuit boards 2 in the first direction (X) can be adjusted by the horizontal adjusting component 5, so that the size of the hot-pressed forming plate 1 in the first direction (X) between the two circuit boards 2 is adjusted, and further the size of the hot-pressed forming plate 1 in the first direction can be compatible with the size of the battery cell in the first direction (X). Also, since a circuit board 2 is respectively connected to the first frame 3 and the second frame 4, at least one of the first frame 3 and the second frame 4 moves along the second direction Z with the vertical adjusting component 6 to change the size of at least one of the first frame 3 and the second frame 4 in the second direction (Z). Therefore, the size of at least one of the first frame 3 and the second frame 4 in the second direction (Z) can be adjusted by the vertical adjusting component 6, and further the position of the circuit board 2 connected to the first frame 3 and the second frame 4 in the second direction (Z) is changed, so as to ensure that the circuit board 2 on the hot-pressed forming plate 1 can contact the tab of the battery cell, so as to be compatible with the size of the battery cell in the second direction (Z). In summary, the position of the circuit board 2 in the first direction (X) can be adjusted by the horizontal adjusting component 5 to meet the hot-pressing forming requirements of battery cells with different sizes in the first direction (X), and the position of the circuit board 2 in the second direction (Z) can be adjusted by the vertical adjusting component 6 to be compatible with battery cells with different sizes in the second direction (Z) and battery cells with different tab positions in the second direction (Z), thereby improving the compatibility of the hot-pressed forming plate 1 with different battery cells and the adaptability of the hot-pressed forming plate 1.

[0048] Among them, in the above embodiments, the hot-pressed forming plate 1 can be used not only for hot-pressing forming single-sided tab battery cells but also for hot-pressing forming double-sided tab battery cells. A circuit board 2 is provided at each of the two ends of the hot-pressed forming plate 1 in the first direction (X). In this way, whether it is a single-sided tab battery cell or a double-sided tab battery cell, hot-pressing forming can be carried out through the hot-pressed forming plate 1. In other words, when hot-pressing forming a single-sided tab battery cell, only the circuit board 2 at one end of the hot-pressed forming plate 1 needs to contact the circuit board 2, and when hot-pressing forming a double-sided tab battery cell, the circuit boards 2 at both ends of the hot-pressed forming plate 1 need to contact the circuit board 2. It should be noted that when hot-pressing forming a single-sided tab battery cell, since the positive tab and the negative tab of the battery cell are located on the same side of the battery cell, the circuit board 2 at one end of the forming plate should be a bipolar circuit board.

[0049] It should be noted that both the first frame 3 and the second frame 4 are square frame structures, that is, both the first frame 3 and the second frame 4 can be frame structures composed of multiple rod-shaped structures. The shapes of the first frame 3 and the second frame 4 can be the same or different, and the embodiments of the present invention do not limit this. The first frame 3 is connected to the circuit board 2 at one end of the hot pressing forming plate 1, and the second frame 4 is connected to the circuit board 2 at the other end of the hot pressing forming plate 1. Furthermore, the horizontal adjustment assembly 5 can control the distance between the first frame 3 and the second frame 4 in the first direction (X), control the distance between the first circuit board 2 and the second circuit board 2 in the first direction (X), so that the size of the hot pressing forming plate 1 between the two circuit boards 2 in the first direction (X) is adjusted, and further the size of the hot pressing forming plate 1 in the first direction can be compatible with the size of the battery cell in the first direction (X). The horizontal adjustment assembly 5 can be a sliding structure, a motor screw structure, a screw nut structure, or other structures that can linearly adjust the distance, and the embodiments of the present invention do not limit this.

[0050] In addition, when hot pressing and forming a single-sided tab battery cell, since the positive tab and the negative tab of the battery cell are located on the same side of the battery cell, it is necessary to adjust the relative position of the bipolar circuit board 2 in the second direction (Z) so that both the positive tab and the negative tab of the battery cell can contact the bipolar circuit board. In addition, it should be noted that in the embodiments of the present invention, the vertical adjustment assembly 6 is movably connected to at least one of the first frame 3 and the second frame 4, and at least one of the first frame 3 and the second frame 4 moves along the second direction Z with the vertical adjustment assembly 6, that is, it can make the first frame 3 or the second frame 4 move along the second direction Z with the vertical adjustment assembly 6, or it can make both the first frame 3 and the second frame 4 move along the second direction Z with the vertical adjustment assembly 6. In other words, it can make the circuit board 2 at any end of the hot pressing forming plate 1 change its position with the change of the size of at least one of the first frame 3 and the second frame 4 in the second direction (Z), or it can make the circuit boards 2 at both ends of the hot pressing forming plate 1 change their positions with the change of the size of the first frame 3 and the second frame 4 in the second direction (Z). In addition, the vertical adjustment assembly 6 can be a sliding structure, a motor screw structure, a screw nut structure, or other structures that can linearly adjust the distance, and the embodiments of the present invention do not limit this.

[0051] It should be noted that according to Figure 1, in the embodiment of the present utility model, the X-axis direction and the Z-axis direction intersect, and the Y-axis direction intersects with the Z-axis and the X-axis simultaneously. For the convenience of description, the first direction is defined as the X-axis direction (that is, the direction in which the horizontal adjustment component 5 adjusts the circuit board 2 in the embodiment of the present utility model), the second direction is defined as the Z-axis direction (that is, the direction in which the vertical adjustment component 6 adjusts the circuit board 2 in the embodiment of the present utility model), and the third direction is defined as the Y-axis direction (that is, the direction in which the insertion piece 7 adjusts the circuit board 2 in the embodiment of the present utility model). Further explanation, the definition of perpendicularity in the specification should be understood as perpendicular within a ten percent floating range of ninety degrees, that is, the included angle between the defined first direction and the second direction should be understood as perpendicular when it is between eighty degrees and ninety degrees, and the included angle between the defined second direction and the third direction should be understood as perpendicular when it is between eighty degrees and ninety degrees.

[0052] Next, the specific structures of the horizontal adjustment component 5 and the vertical adjustment component 6 in the embodiment of the present utility model will be specifically introduced as follows:

[0053] In some embodiments, such as Figure 2 and Figure 3 shown, for the structures of the first frame 3 and the second frame 4, the first frame 3 includes a first guide rod 31 and a second guide rod 32 extending along the third direction (Y), the first guide rod 31 and the second guide rod 32 are connected by a first support rod 33, and the first guide rod 31 and the second guide rod 32 are spaced apart in the second direction (Z); the second frame 4 includes a third guide rod 41 and a fourth guide rod 42 extending along the third direction (Y), the third guide rod 41 and the fourth guide rod 42 are connected by a second support rod 43, and the third guide rod 41 and the fourth guide rod 42 are spaced apart in the second direction (Z), wherein the third direction (Y) is the direction that intersects with both the first direction (X) and the second direction (Z); the first support rod 33 and the second support rod 43 are connected by a horizontal adjustment component 5.

[0054] In this embodiment, the first support rod 33 and the second support rod 43 can be of a cuboid structure, a cylindrical structure, or other shapes, and the embodiment of the present utility model does not limit this. Both the first support rod 33 and the second support rod 43 extend along the second direction (Z), and the number of the first support rods 33 and the number of the second support rods 43 can both be two, such that a first quadrilateral frame-like structure is formed between the first guide rod 31, the second guide rod 32, and the two first support rods 33 (such as Figure 1 , one on each of the left and right sides), such that a structure is formed between the third guide rod 41, the fourth guide rod 42, and the two second support rods 43 (such as Figure 1, a second quadrilateral frame-like structure is formed between them (one on each of the left and right sides), and the hot-pressed plate 1 is connected between the first quadrilateral frame-like structure and the second quadrilateral frame-like structure. The first quadrilateral frame-like structure and the second quadrilateral frame structure are compatible with different types and sizes of battery cells by adjusting the positions of the two circuit boards 2. In this way, since the first support rod 33 and the second support rod 43 are connected by the horizontal adjustment assembly 5, the distance between the first support rod 33 and the second support rod 43 in the first direction (X) can be adjusted through the horizontal adjustment assembly 5. Furthermore, the distance between the first quadrilateral frame-like structure and the second quadrilateral frame-like structure in the first direction (X) can be adjusted, indirectly adjusting the distance between the two circuit boards 2 in the first direction (X), so that the two circuit boards 2 can be compatible with different sizes of battery cells in the first direction (X).

[0055] In some feasible embodiments, the horizontal adjustment assembly 5 includes a handwheel 51 and a reverse screw 52; one end of the reverse screw 52 is indirectly connected to the first support rod 33 through other parts, and the other end of the reverse screw 52 extends along the first direction (X) and passes through the second support rod 43 to be connected to the handwheel 51; when the handwheel 51 rotates in the first rotation direction, the first frame 3 and the second frame 4 approach each other along the first direction (X), and when the handwheel 51 rotates in the second rotation direction, the first frame 3 and the second frame 4 move away from each other along the first direction (X), where the first rotation direction and the second rotation direction are two opposite rotation directions.

[0056] In this embodiment, when the handwheel 51 rotates in the first rotation direction, the first frame 3 and the second frame 4 approach each other along the first direction (X), so that the distance between the first quadrilateral frame-like structure and the second quadrilateral frame-like structure in the first direction (X) decreases, indirectly reducing the distance between the two circuit boards 2 in the first direction (X), and further enabling the two circuit boards 2 to be compatible with smaller-sized battery cells in the first direction (X). On the contrary, when the handwheel 51 rotates in the second rotation direction, the first frame 3 and the second frame 4 move away from each other along the first direction (X), so that the distance between the first quadrilateral frame-like structure and the second quadrilateral frame-like structure in the first direction (X) increases, indirectly increasing the distance between the two circuit boards 2 in the first direction (X), and further enabling the two circuit boards 2 to be compatible with larger-sized battery cells in the first direction (X).

[0057] Further, the reverse screw 52 includes a first screw 521 and a second screw 522 connected to each other. The thread helix direction on the first screw 521 is opposite to that on the second screw 522. A first nut seat is provided on the first support rod 33, and a second nut seat is provided on the second support rod 43. The end of the first screw 521 passes through the first nut seat, and the end of the second screw 522 passes through the second nut seat and is fixedly connected to the handwheel 51.

[0058] It should be noted that in this embodiment, since the thread helix direction on the first screw 521 is opposite to that on the second screw 522, the thread helix direction of the first screw 521 cooperating with the first nut seat is the first helix direction, and the thread helix direction of the second screw 522 cooperating with the second nut seat is the second helix direction, where the first helix direction and the second helix direction are opposite. Thus, since the first nut seat is provided on the first support rod 33 and the second nut seat is provided on the second support rod 43, when the handwheel 51 rotates in the first rotation direction, the helix direction of the first screw 521 approaches the second screw 522, and the helix direction of the second screw 522 approaches the first screw 521, so that the distance between the first quadrilateral frame-like structure and the second quadrilateral frame-like structure in the first direction (X) is reduced, indirectly reducing the distance between the two circuit boards 2 in the first direction (X), and further enabling the two circuit boards 2 to be compatible with the smaller-sized battery cells in the first direction (X). On the contrary, when the handwheel 51 rotates in the second rotation direction, the helix direction of the first screw 521 moves away from the second screw 522, and the helix direction of the second screw 522 moves away from the first screw 521, so that the distance between the first quadrilateral frame-like structure and the second quadrilateral frame-like structure in the first direction (X) is increased, indirectly increasing the distance between the two circuit boards 2 in the first direction (X), and further enabling the two circuit boards 2 to be compatible with the larger-sized battery cells in the first direction (X).

[0059] In some embodiments, in the second direction (Z), the vertical adjustment assembly 6 is movably connected to the first support rod 33, the second guide rod 32 is connected to the vertical adjustment assembly 6, and the first end of the circuit board 2 provided at one end of the hot pressing and forming plate 1 in the first direction (X) is fixed to the second guide rod 32, and the first end is the end of the circuit board 2 in the second direction (Z).

[0060] It should be noted that the vertical adjustment assembly 6 can be slidably connected to the first support rod 33 by means of sliding connection, threaded connection and other connection methods, so that the second guide rod 32 in the vertical adjustment assembly 6 can move on the first support rod 33 along the second direction (Z). Also, since the second guide rod 32 is connected to the vertical adjustment assembly 6, and the first end of the circuit board 2 provided at one end of the hot pressing and forming plate 1 in the first direction (X) is fixed to the second guide rod 32, therefore, as the second guide rod 32 in the vertical adjustment assembly 6 can move along the second direction (Z), it finally drives the circuit board 2 to move in the second direction (Z), realizing the adjustment of the position of the circuit board 2 in the second direction (Z).

[0061] In some feasible embodiments, the structure of the vertical adjustment assembly 6 can be: the vertical adjustment assembly 6 includes a rotating wheel 61, a Z-axis screw 62 and a Z-axis nut 63; one end of the Z-axis screw 62 is fixed to the rotating wheel 61, and the other end of the Z-axis screw 62 passes through the Z-axis nut 63 and is movably connected to the second guide rod 32. When the rotating wheel 61 rotates, the second guide rod 32 moves along the second direction (Z); the end of the circuit board 2 provided at one end of the hot pressing and forming plate 1 in the second direction (Z) is movably connected to the second guide rod 32.

[0062] In this embodiment, the Z-axis screw 62 extends along the second direction (Z). The Z-axis screw 62 is disposed on one side of the first support rod 33. Generally, the Z-axis screw 62 needs to pass through the ends of the first guide rod 31, the Z-axis nut 63, and the second guide rod 32. In other words, the second guide rod 32 is movably connected to the first support rod 33 through the Z-axis screw 62. Thus, when the rotation direction of the rotating wheel 61 is the same as the helix direction of the Z-axis screw 62, the second guide rod 32 moves in a direction approaching the first guide rod 31. When the rotation direction of the rotating wheel 61 is opposite to the helix direction of the Z-axis screw 62, the second guide rod 32 moves in a direction away from the first guide rod 31. Since one end of the circuit board 2 disposed on the hot pressing and forming plate 1 is fixed to the second guide rod 32 at the end in the second direction (Z), the position of the circuit board 2 in the second direction (Z) can be changed as the second guide rod 32 moves, realizing the adjustment of the position of the circuit board 2 in the second direction (Z). It should be noted that the end of the circuit board 2 disposed at one end of the hot pressing and forming plate 1 in the second direction can be movably connected to the second guide rod 32 through a hanging ring, a buckle, a pin, or other forms, and the embodiment of the present invention does not limit this. In addition, when hot pressing and forming a single-sided tab cell, since the positive tab and the negative tab of the cell are located on the same side of the cell, generally, when hot pressing and forming a single-sided tab cell, the position of the circuit board 2 in the second direction (Z) needs to be adjusted so that the positive tab and the negative tab of the cell can be in contact with the circuit board 2 simultaneously. Based on this, the circuit board 2 fixed to the second guide rod 32 in this embodiment is generally a bipolar circuit board 2.

[0063] Further, as Figure 4 shown, in some embodiments, a sliding seat 64 is connected to the end of the second guide rod 32. The first support rod 33 is provided with a slide rail plate 65 extending along the second direction (Z). The sliding seat 64 is mounted on the slide rail plate 65; a threaded hole is formed in the sliding seat 64, and the Z-axis screw 62 passes through the threaded hole and is connected to the sliding seat 64.

[0064] In this embodiment, the slide rail plate 65 and the first support rod 33 are stacked. The size of the slide rail plate 65 in the first direction (X) is smaller than the size of the first support rod 33 in the first direction (X). The first end of the sliding seat 64 is connected to the second guide rod 32, and the sliding seat 64 is mounted on the slide rail plate 65. Thus, the slide rail plate 65 can slide along the second direction (Z), and further, the position of the circuit board 2 in the second direction (Z) is adjustable. Thus, when the Z-axis screw 62 rotates in different helix directions, the sliding seat 64 and the second guide rod 32 can move in a direction approaching or away from the first guide rod 31.

[0065] Optionally, as Figure 5 and Figure 6As shown, in some embodiments, a strip component 11 and tab are further provided on the hot pressing forming plate 1. The strip component 11 presses and bonds the circuit board 2 and the tab in the third direction (Y). The circuit board 2 is fixed on the mounting plate 14. The end of the mounting plate 14 in the second direction (Z) has a hanging loop, and the hanging loop is connected to the second guide rod 32.

[0066] It should be noted that the strip component 11 can be a metal sheet or a strip-shaped object, and its surface is made of insulating material. Since the strip component 11 will contact the circuit board 2 on the adjacent hot pressing forming plate 1 during the no-load pressing of the equipment, therefore: in the actual use process, when the battery cells are placed between the hot pressing forming plates 1 and the tabs are aligned with the positions of the circuit boards 2, after the equipment is pressed, the strip component 11 will press the tabs on the circuit boards 2. Therefore, the battery cells can be indirectly connected to external devices (including but not limited to devices such as formation and grading power supplies) through the strip component 11, thereby ensuring stable contact between the battery cells and the external devices. In addition, each hot pressing forming plate 1 is equipped with 2 circuit boards 2 or 2 strip components 11, or 2 circuit boards 2 and 2 strip components 11. Therefore, the circuit board 2 and the strip component 11 on the same hot pressing forming plate 1 should be movably connected. In other words, the relative position between the circuit board 2 and the strip component 11 in the second direction (Z) can change. Also, since the end of the mounting plate 14 in the second direction (Z) has a hanging loop, and the hanging loop is fixed on the second guide rod 32, the relative position of the circuit board 2 in the second direction (Z) can be indirectly changed by changing the relative position of the second guide rod 32 in the second direction (Z), and it will not affect the relative position of the strip component 11 in the second direction (Z).

[0067] Furthermore, as Figure 5 and Figure 6 shown, the strip component 11 and the mounting plate 14 are slidably connected between the first mounting seat 12 and the second mounting seat 13. The first end of the first mounting seat 12 is fixed on the strip component 11, the second end of the first mounting seat 12 abuts against the mounting plate 14, the first end of the second mounting seat 13 is fixed on the strip component 11, and the second end of the second mounting seat 13 abuts against the mounting plate 14.

[0068] In this embodiment, the first mounting base 12 and the second mounting base 13 are arranged at intervals, that is, the first mounting base 12 and the second mounting base 13 are respectively arranged at intervals in the second direction (Z), so that there are two different mounting and fixing points between the pressing strip assembly 11 and the mounting plate 14. The second end of the first mounting base 12 can be abutted against the mounting plate 14 by means of magnetic attraction, pressing, spring traction, etc., and the second end of the second mounting base 13 can also be abutted against the mounting plate 14 by means of magnetic attraction, pressing, spring traction, etc. The circuit board 2 is fixed on the surface of the mounting plate 14 by means of bolts or buckles, etc., so that the mounting plate 14 and the circuit board 2 are detachably connected to the pressing strip assembly 11 in the third direction (Y), and thus it is convenient to adjust the distance between the circuit board 2 and the pressing strip assembly 11 in the third direction (Y).

[0069] In some embodiments, the adjusting device further includes an inserting piece 7; when the inserting piece 7 is inserted between the second end of the first mounting base 12 and the mounting plate 14 and when the inserting piece 7 is inserted between the second end of the second mounting base 13 and the mounting plate 14, the distance between the circuit board 2 and the pressing strip assembly 11 changes in the third direction (Y), wherein the third direction (Y) is a direction that intersects the first direction (X) and the second direction (Z) at the same time.

[0070] It should be noted that in some application scenarios, when the device is pressed, if there is a relative position difference between the tab of the battery cell and the surface of the circuit board 2 in the third direction (Y) in the flattened shape, the tab of the battery cell will be bent, which will affect the flatness of the tab of the battery cell after hot pressing and forming. Based on this, in the embodiment of the present invention, the relative position of the circuit board 2 in the third direction (Y) can be changed by adding an insert piece 7 between the circuit board 2 and the pressing strip assembly 11. When connecting, the mounting plate 14 and the pressing strip assembly 11 can be separated first so that there is a gap between the mounting plate 14 and the pressing strip assembly 11, and then the insert piece 7 is inserted between the second end of the first mounting seat 12 and the mounting plate 14, and the insert piece 7 is inserted between the second end of the second mounting seat 13 and the mounting plate 14, so that the distance between the circuit board 2 and the pressing strip assembly 11 in the third direction (Y) changes, and thus the relative position of the circuit board 2 in the third direction (Y) changes. It should also be noted that since the thicknesses of different insert pieces 7 are different, when different thicknesses of insert pieces 7 are inserted between the second end of the first mounting seat 12 and the mounting plate 14 and between the second end of the second mounting seat 13 and the mounting plate 14, the circuit board 2 can be in different positions in the third direction (Y). To sum up, the embodiment of the present invention can not only adjust the relative position of the circuit board 2 in the second direction (Z), but also adjust the relative position of the circuit board 2 in the third direction (Y), so that the relative position of the circuit board 2 in each direction is adjustable, making the hot pressing and forming plate 1 compatible with battery cells of any size and further improving the adaptability of the hot pressing and forming plate 1. It should also be noted that the above insert piece can also be replaced by other structures, such as elastic parts, clamping parts, etc., and the embodiment of the present invention does not limit this.

[0071] In addition, the vertical adjustment assembly 6 and the horizontal adjustment assembly 5 in any of the above embodiments can be automatically adjusted through a driving assembly. The driving assembly can be a motor, a cylinder or other driving assemblies, and the embodiment of the present invention does not limit this.

[0072] As can be seen from the above embodiments, in the embodiments of the present utility model, the distance between the two circuit boards 2 in the first direction (X) can be adjusted by the horizontal adjustment component 5, so that the size of the hot pressing and forming board 1 between the two circuit boards 2 in the first direction (X) can be adjusted, and further the size of the hot pressing and forming board 1 in the first direction can be compatible with the size of the battery cell in the first direction (X). Moreover, the size of at least one of the first frame 3 and the second frame 4 in the second direction (Z) can be adjusted by the vertical adjustment component 6, and then the position of the circuit board 2 connected to the first frame 3 and the second frame 4 in the second direction (Z) can be changed, so as to ensure that the circuit board 2 on the hot pressing and forming board 1 can contact the tab of the battery cell, so as to be compatible with the size of the battery cell in the second direction (Z). In addition, the relative position of the circuit board 2 in the third direction (Y) can be changed by adding an insert piece 7 between the circuit board 2 and the pressing strip component 11. In summary, the embodiments of the present utility model can not only make the circuit board compatible with the hot pressing and forming requirements of battery cells with different sizes in the first direction (X), the second direction (Z), and the third direction (Y), but also improve the compatibility of the hot pressing and forming board 1 with different battery cells and the adaptability of the hot pressing and forming board 1.
