The abutting assembly comprises an abutting piece 21, which is oppositely arranged with the limiting block 11 along a first direction of the bearing surface. The abutting piece 21 is movably mounted on the bearing seat along the first direction and a second direction of the bearing surface. The abutting piece 21 and the limiting block 11 are used to clamp the battery. The film covering mechanism is spaced apart from the bearing seat 1 and is used to cover the battery film onto the battery. Wherein, Figure 1 It can be known that the first direction intersects with the second direction. Specifically, the first direction and the second direction are arranged perpendicular to each other.

[0048] In the embodiment provided by the application, the battery film and the battery are sequentially placed on the bearing surface, the abutting part 21 abuts the battery to the limiting block 11 by moving in the first direction, and after the battery is limited in the fixed position, the battery and the battery film are heat-welded, when the top of the battery needs to be heat-welded, the abutting part 21 is controlled to move in the second direction to form a avoiding space, so that the battery film can be folded to the top of the battery without being shielded, and after the folding is completed, the battery film and the battery can be heat-welded, and the battery can be clamped again, so as to complete the heat-welding of the top film of the battery, without manual participation in the film process, and the film efficiency and the film quality are guaranteed.

[0049] Further embodiments of the battery cell clamping device for battery cell clamping are described in detail with reference to Figure 1 、 Figure 2 , including a bearing seat 1 and an abutting mechanism, the abutting mechanism including a driving assembly, an abutting assembly, and a synchronous assembly; wherein the abutting assembly is slidingly installed on the synchronous assembly, the abutting assembly including a sliding support 22 and an abutting part 21; the abutting assembly is slidingly connected with the sliding support 22, and the sliding support 22 is slidingly connected with the bearing seat 1. Specifically, the sliding support 22 is movably installed on the bearing seat 1 in the second direction, and the abutting part 21 is movably installed on the sliding support 22 in the first direction; the synchronous assembly is arranged between the bearing seat 1 and the abutting part 21 to synchronize the movement of the sliding support 22 and the abutting part 21. In this embodiment, the abutting part 21 is simultaneously moved in the first direction and the second direction by the synchronous assembly, so that the abutting part 21 can simultaneously loosen the battery and avoid the battery film, facilitating the control of the abutting part 21 and simplifying the operation process without sequentially controlling the abutting part 21 to move in different directions.

[0050] In the above embodiment, the abutting part 21 includes a connecting bracket and an abutting plate, one end of the connecting bracket is slidingly connected to the sliding support 22 through a sliding block, the other end of the connecting bracket is connected with the abutting block, and the abutting block is located above the bearing surface. Figure 2

[0051] It should be noted that the synchronous assembly has various embodiments, for example, an electrical synchronous control software is arranged to simultaneously control the driving of the driving device to drive the sliding support 22 and the abutting part 21 to move.

[0052] ​In the embodiment, the synchronous assembly comprises a guide block 231 and a transmission member 232, the transmission member 232 is configured to slide in abutment with the guide slope, the guide block 231 is mounted on the bearing seat 1 and is spaced apart from the sliding support 22 along the third direction perpendicular to the bearing surface, the guide slope is formed on the guide block 231, the guide slope is perpendicular to the bearing surface and is inclined along the second direction, and the transmission member 232 extends along the first direction, one end of the transmission member is mounted on the abutting member 21, and the other end of the transmission member is in abutment with the guide slope.

[0053] In the above embodiment, the transmission member 232 extends along the first direction and is in abutment with the guide slope, when the sliding support moves along the second direction, the transmission member 232 moves along the guide slope, because the guide slope is inclined along the second direction, the guide slope has a height difference along the first direction, and the transmission member 232 moves along the first direction during the movement along the second direction, thereby driving the abutting member 21 to move along the first direction, so that the abutting member 21 moves along the two directions through the mechanical structure, the structure is simple and reliable, and the misoperation caused by the separate driving through multiple driving devices or structures is avoided.

[0054] It should be noted that, in order to facilitate the abutment of the transmission member 232 on the guide slope, the synchronous assembly further comprises a first elastic member, the first elastic member is mounted between the abutting member 21 and the sliding support 22 and is used to drive the abutting member 21 to move towards the sliding support 22. In the embodiment, the first elastic member drives the abutting member 21 to move towards the sliding support 22, thereby abutting the transmission member 232 on the guide slope and ensuring the movement of the abutting member 21 along the second direction.

[0055] In the embodiment, the first elastic member is a spring, so as to automatically drive the abutting member 21 to move.

[0056] Specifically, as shown in Figure 2 the above embodiment, the sliding support 22 is provided with a sliding rod, the sliding block is slidably connected with the sliding rod, the connecting bracket is connected to the sliding block through bolts, and the first elastic member is sleeved on the sliding rod.

[0057] In addition, in the embodiment, the guide slope is arc-shaped, so as to facilitate the movement of the transmission member 232.

[0058] Similarly, the end of the transmission member 232 in abutment with the guide slope is provided with a roller, so as to facilitate the movement of the transmission member 232 on the guide slope.

[0059] Further, in the above embodiment, the driving assembly comprises a support base 241 and a driving block 242; one end of the driving block 242 is movably mounted to the support base 241 in the second direction, and the other end is abutted to the sliding support 22, so as to drive the sliding support 22 to move in the second direction. In this embodiment, the driving block is abutted to the sliding support 22, and the sliding support 22 is driven to move in the second direction by the movement of the driving block 242 in the second direction, so as to facilitate the installation and replacement of the driving assembly.

[0060] In addition, in this embodiment, the driving assembly further comprises a second elastic member, which is mounted between the sliding support 22 and the bearing seat 1, so as to drive the sliding support to move along the guide slope. In this embodiment, the driving block 242 is abutted to the sliding support 22, so as to control the sliding support 22 to move in the second direction. In order to facilitate the automatic recovery of the sliding support 22 to the original state, the second elastic member is arranged between the sliding support and the bearing seat 1, so that after the force of the driving block 242 is removed, the sliding support 22 automatically rebounds to the original state. When the driving block 242 drives the sliding support 22 to move, the abutting member 21 can simultaneously move in the first direction and the second direction. After the abutting force of the driving block 242 is removed, the abutting member 21 can automatically recover to the original state in the first direction and the second direction. It is not necessary to arrange driving elements in multiple directions.

[0061] Specifically, in this embodiment, the second elastic member is also a spring.

[0062] Further, the support base 241 comprises a fixed base 2411 and a support bracket 2412; the support bracket 2412 is movably mounted to the fixed base 2411 in the third direction, and the driving block 242 is movably mounted to the support bracket 2412 in the second direction. When the sliding support 22 does not need to be driven to move, the support bracket 2412 is moved in the third direction, so that the driving block 242 is separated from the sliding support 22, and the driving block 242 does not hinder the sliding support 22.

[0063] In a specific embodiment provided by the application, in the second direction, the bearing seat 1 comprises an abutting end and a relaxed end.

[0064] The sliding support 22 is slidably mounted to the bearing seat 1 through the cooperation of the sliding groove and the sliding rail, and the second elastic member is arranged between the sliding support 22 and the bearing seat 1, so as to drive the sliding support 22 to move towards the abutting end.

[0065] The sliding rail and the sliding groove are also arranged between the abutting member 21 and the sliding support 22, so as to facilitate the sliding of the abutting member 21; the first elastic member is arranged between the abutting member 21 and the sliding support 22, so as to drive the abutting member 21 to move towards the sliding support 22.

[0066] The bearing seat 1 is further provided with a guide block 231, and an inclined guide surface is formed on the end surface of the guide block 231 away from the bearing seat 1, and the abutting member 21 is abutted on the inclined guide surface through a transmission member 232.

[0067] In use, when the sliding support 22 is not subjected to force, the second elastic member drives the sliding support 22 to move towards the abutting end, the transmission member 232 slides along the inclined guide surface, so that the abutting member 21 moves towards the sliding support 22, and the distance between the abutting member 21 and the limiting block 11 is reduced to clamp the battery.

[0068] When the sliding support 22 is driven by the abutting driving block 242 to move towards the relaxation end, the abutting member 21 moves away from the sliding support 22 to release the battery, and the abutting member 21 moves in the second direction to form a avoiding space, which facilitates the folding of the battery film.

[0069] In addition, in the embodiment, the abutting mechanism is provided with two groups, and the two groups of abutting mechanisms are spaced apart in the second direction to facilitate more stable clamping of the battery.

[0070] The two groups of abutting mechanisms are mirror images in the second direction to facilitate simultaneous clamping or releasing of the battery and avoiding the battery film.

[0071] On the other hand, referring to Figure 4 , the film clamping mechanism includes a mounting frame 31, a movable support 32, and a clamping jaw 33; the mounting frame 31 is spaced apart from the bearing seat 1 in the first direction; the movable support 32 is movably mounted to the mounting frame 31 in the first direction and in a third direction perpendicular to the bearing surface; and the clamping jaw 33 is mounted to the movable support 32 to clamp the battery film. In the embodiment, the clamping jaw 33 clamps the battery film, and the movable support 32 moves in the first direction and in the third direction to fold the battery film to the top of the battery.

[0072] It should be noted that there are various ways to movably mount the movable support 32 to the mounting frame 31, and in the embodiment, the film clamping mechanism further includes a first support movably mounted to the mounting frame 31 in the first direction, and the movable support 32 is movably mounted to the first support in the third direction.

[0073] The first support and the mounting frame 31 are movably connected through a slide rail, and similarly, the movable support 32 and the first support are also movably connected through a slide rail.

[0074] Further, in order to facilitate the battery film to be attached to the top of the battery, the clamping jaw 33 is formed with a clamping jaw opening extending in the second direction, and the clamping jaw 33 is rotatably mounted to the movable support 32 about an axis in the second direction, so that the clamping jaw 33 can rotate when the battery film is folded.

[0075] In the embodiment, the clamping claws 33 are installed on the rotating shaft, the rotating shaft is rotatably installed on the movable support 32 along the axis in the second direction, and the rotating shaft is driven to rotate by the driving motor and the transmission belt.

[0076] It should be noted that in the embodiment, two clamping claws 33 are provided, and the clamping jaw openings of the two clamping claws 33 are oppositely arranged so as to simultaneously clamp the two ends of the battery film.

[0077] In addition, referring to Figure 5 , the film covering mechanism further comprises a pressing table 34 movably installed on the bearing seat 1 along the third direction and arranged corresponding to the bearing surface. The battery film is pressed on the top end of the battery by the pressing table 34, so as to heat and melt the film on the battery.

[0078] Similarly, the film covering mechanism further comprises a heat melting piece 35 movably installed on the bearing seat 1 along the third direction and arranged corresponding to the bearing surface, which is used to heat and melt the battery film to the battery.

[0079] It should be noted that the pressing table 34 and the heat melting piece 35 can be selectively provided or simultaneously provided, and no specific limitation is made herein.

[0080] On the other hand, as shown in Figure 1 , the bearing surface further comprises a limiting assembly, the limiting assembly is arranged on the bearing surface, and the limiting assembly can move and right the battery cell so that the battery cell can be arranged at a preset position in a preset form. The limiting assembly comprises two movable rods 41 and a wedge block 42. The two movable rods 41 are movably arranged along the second direction and are movably installed on the bearing surface along the second direction. The two ends of the movable rod 41 are respectively a driving end and an installation end. The two driving ends are arranged adjacent to each other, and the two installation ends are respectively provided with a clamping plate. The two clamping plates are used to clamp the battery. The wedge block 42 is movably arranged between the two movable rods 41 along the third direction perpendicular to the bearing surface. The wedge block is formed with a driving slope on the end surface relative to the movable rod. The driving end is abutted to the driving slope. In the embodiment, the position of the battery is limited in the first direction by the limiting block 11 and the abutting piece 21. In order to ensure the position of the battery in the second direction, the battery is clamped by the two movable rods 41. When the wedge block 42 moves, the two movable rods 41 are simultaneously driven to move along the second direction, and the two clamping plates simultaneously clamp the battery.

[0081] Specifically, by Figure 1It can be known that the preset shape can be that the battery cell is in a righted shape, and the preset position can be a clamped center position. For example, when the battery cell is a rectangular battery cell, the two movable rods 41 on two sides can clamp the battery cell, so that the two adjacent straight edges of the battery cell are parallel to the first direction and the second direction, respectively. At this time, the battery cell is in a righted shape through the clamping of the movable rods 41, and the movable rods 41 on two sides can move the battery cell to the clamped center position while righting the battery cell.

[0082] In addition, a plurality of suction cups are arranged on the bearing surface. In order to adsorb the battery film after the battery film is placed on the bearing surface, displacement is avoided in the processing process.

[0083] Similarly, a plurality of claw avoiding grooves and detection through holes are concavely arranged on the bearing surface. In order to place the battery film and the battery by the external claw without interference with the bearing surface; the detection through hole is used to detect the contact state between the battery and the bottom battery film by the external detection device through the detection through hole, so as to avoid that the battery film does not cover the bottom of the battery.

[0084] Similarly, three bearing areas adjacent to each other along the first direction are formed on the bearing surface, and are used to bear different positions of the battery film, respectively. In the embodiment, since the area of the battery film is larger than the area of the bottom of the battery after the battery film is placed on the bearing surface, the three bearing areas bear the part of the battery film covering the bottom of the battery, the part of the battery film covering the side and the part of the battery film covering the top, respectively, so as to avoid deformation of the battery film and to facilitate the operation of the film mechanism on the battery film.

[0085] It should be noted that the suction cup, the claw avoiding groove and the bearing area can be selected to exist or can exist simultaneously, and are not limited specifically herein.

[0086] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
