[0057] See also Figure 1 , Figure 2 and Figure 5 An embodiment of the present invention provides a cell processing device, including a frame 10, a transfer device 20 and a handling device 30.

[0058] The battery cell processing equipment has a loading station and at least two processing stations arranged in sequence along a first direction. The transfer device 20 is arranged on the frame 10, and is used to receive the battery cell and transfer the battery cell to the loading station. The transport device 30 includes a transport drive assembly 31 (see Figure 5 ) and at least two clamping components 32 (see Figure 5 The loading station and each processing station are correspondingly provided with a clamping assembly 32. The transport drive assembly 31 is disposed on the frame 10 and is transmission-connected with each clamping assembly 32 to drive each clamping assembly 32 to synchronously reciprocate along the first direction.

[0059] In which, when the transport drive component 31 drives each clamping component 32 to move synchronously back and forth along the first direction, each clamping component 32 can clamp the battery cell of its corresponding loading station or processing station and transport the battery cell to the processing station located on the downstream side of the corresponding loading station or processing station.

[0060] The above-mentioned battery cell processing equipment has a loading station and at least two processing stations, which are arranged in sequence along the first direction at intervals. When processing the battery cells, the transfer device 20 receives the battery cells input from the upstream, and transfers the battery cells to the loading station, and then continuously transfers the battery cells to the processing station. At the same time, driven by the transport drive assembly 31 of the transport device 30, each clamping assembly 32 synchronously reciprocates along the first direction, so that each clamping assembly 32 clamps the battery cells on the corresponding loading station or processing station, and transports the clamped battery cells to the processing station located on the downstream side of the corresponding loading station or processing station, thereby realizing the battery cells on the loading station to the downstream processing stations in sequence. Compared with the prior art, the battery cells located at each processing station can be processed at the same time, and the battery cell circulation rhythm is compact, which is conducive to improving production efficiency, and the equipment structure is compact, which is conducive to saving the required occupied space. It should be noted that, specifically with regard to Figure 1 In the illustrated embodiment, the first direction is the left-right direction.

[0061] See also Figure 2 and Figure 3 As shown, in an embodiment of the present invention, the transfer device 20 includes a transfer clamping assembly 21 and a transfer driving assembly 22. The transfer clamping assembly 21 includes a transfer clamping drive 211 and two transfer clamping jaws 212 that are transmission-connected to the transfer clamping drive 211. Each transfer clamping jaw 212 has a plurality of clamping portions 2121 arranged in sequence, and a first avoidance space a is formed between each two adjacent clamping portions 2121. The transfer clamping drive 211 is used to drive the clamping portions 2121 of the two transfer clamping jaws 212 to clamp or release the battery cell, that is, the transfer clamping drive 211 can drive the two transfer clamping jaws 212 to close together, thereby using the clamping portions 2121 of the two transfer clamping jaws 212 to clamp the battery cell; the transfer clamping drive 211 can drive the two transfer clamping jaws 212 to open each other, thereby causing the clamping portions 2121 of the two transfer clamping jaws 212 to release the battery cell.

[0062] The transfer drive assembly 22 is connected to the transfer clamping drive member 211 to drive the transfer clamping drive member 211 to move, thereby driving the two transfer jaws 212 to move to the loading station, and then, under the drive of the transfer clamping drive member 211, the clamping parts 2121 of the two transfer jaws 212 can release the battery cells to realize the transfer of the battery cells to the loading station.

[0063] In this way, when transporting the battery cell, first, the transport drive assembly 22 drives the transport clamping drive 211 to move to the receiving position for receiving the battery cell, and the transport clamping drive 211 drives the two transport jaws 212 to close together, so as to clamp the battery cell using the clamping parts 2121 of the two transport jaws 212. Then, the transport drive assembly 22 drives the transport clamping drive 211 to move toward the loading station until the battery cell clamped by the two transport jaws 212 moves to the loading station. Then, the transport clamping drive 211 drives the two transport jaws 212 to open each other to release the battery cell to the loading station. Optionally, the transport clamping drive 211 can be a clamping cylinder.

[0064] It should be noted that in actual production, the unloading jaws clamp the wound battery cells on the winding equipment and unload them to the receiving position. It should be noted that the unloading jaws are also comb-shaped. Each transport jaw 212 is designed to have a plurality of clamping parts 2121 arranged in sequence, and a first avoidance space a is formed between each two adjacent clamping parts 2121, so that when the battery cells are clamped at the receiving position, the first avoidance space a between the two adjacent clamping parts 2121 can avoid the comb teeth of the comb-shaped unloading jaws, thereby ensuring that the battery cells can be clamped smoothly from the unloading jaws. After the clamping parts 2121 of the two transport jaws 212 clamp the battery cells, the unloading jaws release the battery cells, thereby completing the acceptance of the battery cells. In this way, the two transfer jaws 212 of the transfer clamping assembly 21 can directly clamp the battery cell on the unloading jaw, thereby avoiding the need to set up a receiving platform at the receiving position. The unloading jaw places the battery cell on the receiving platform, and the two transfer jaws 212 of the transfer clamping assembly 21 clamp the battery cell on the receiving platform, which simplifies the action process of transferring the battery cell and is conducive to improving production efficiency.

[0065] Furthermore, each transport jaw 212 is provided with a avoidance groove 214 that penetrates each clamping portion 2121 along a preset direction on one side of the transport jaw 212 facing the other transport jaw 212, and the avoidance grooves 214 on the two transport jaws 212 are arranged corresponding to each other. Preferably, the preset direction is perpendicular to the arrangement direction of the multiple clamping portions 2121 on the transport jaw 212. Each transport jaw 212 can be provided with one or more avoidance grooves 214. In this way, when receiving the battery cell, the avoidance grooves 214 on the two transport jaws 212 can be inserted into the comb teeth of the comb-shaped feeding jaws to avoid the position, so as to realize the reversing clamping of the battery cell.

[0066] In some embodiments, the transfer device 20 further includes a bearing assembly 23, which includes a first fixed seat 233 disposed on the frame 10 and a support platform disposed on the first fixed seat 233. The support platform has a plurality of support portions 231 for supporting the battery cells and arranged in sequence, and a second avoidance space b is formed between each two adjacent support portions 231. When the transfer drive assembly 22 drives the transfer clamping drive member 211 to move toward the loading station, the plurality of clamping portions 2121 corresponding to a transfer clamp 212 can be inserted into the corresponding second avoidance space b (at the same time, the plurality of support portions 231 can be inserted into the corresponding first avoidance space a), thereby facilitating the release of the battery cells onto the plurality of support portions 231.

[0067] In one embodiment, the support platform is fixed relative to the first fixed seat 233, that is, the support platform does not have a lifting function in the vertical direction. In this embodiment, the bearing assembly 23 also includes a positioning driver 234 and a positioning platform 232, the positioning driver 234 is installed on the first fixed seat 233, and is connected to the positioning platform 232 in a transmission manner to drive the positioning platform 232 to lift relative to the support platform. The positioning platform 232 has a plurality of lifting parts 2321 arranged in sequence, each lifting part 2321 is located in the corresponding second avoidance space b, so that in the process of the positioning platform 232 rising relative to the support platform, the plurality of lifting parts 2321 lift the cells supported on the plurality of supporting parts 231. In this way, the plurality of lifting parts 2321 of the positioning platform 232 are used to lift the cells on the plurality of supporting parts 231, so as to position the cells in the vertical direction, so that the clamping assembly 32 corresponding to the loading station of the handling device 30 can carry the cells on the plurality of lifting parts 2321 to the processing station on the downstream side of the loading station. Alternatively, the positioning drive member 234 may be a cylinder.

[0068] It should be noted that when a small-sized battery cell is released onto the support platform, due to the small size of the battery cell, only one support portion 231 can support the battery cell, making it easy for the battery cell to tilt or fall toward the second avoidance space b between two adjacent support portions 231, resulting in the battery cell processing equipment being incompatible with small-sized batteries. To solve the problem of incompatibility with small-sized batteries, please refer to Figure 4As shown, in another embodiment, the bearing assembly 23 also includes a bearing driver 237, a positioning driver 234 and a positioning platform 232. The support platform is movable in the vertical direction relative to the first fixed seat 233. The bearing driver 237 is installed on the first fixed seat 233 and is connected to the support platform in a transmission manner to drive the support platform to move in the vertical direction (i.e., lift). The positioning driver 234 is installed on the support platform and is connected to the positioning platform 232 in a transmission manner to drive the positioning platform 232 to lift relative to the support platform. The positioning platform 232 has a plurality of jacking portions 2321 arranged in sequence, and each jacking portion 2321 is located in the corresponding second avoidance space b. The positioning platform 232 can be moved under the drive of the positioning driver 234 until the top surface of each jacking portion 2321 is flush with the top surface of each support portion 231. In this way, the lifting part 2321 of the positioning platform 232 can be raised and lowered to be flush with the top surface of the support part 231 under the drive of the positioning driver 234, so that the support part 231 and the lifting part 2321 can be used to support the battery cell A together, and then the bearing driver 237 drives the support platform and the positioning platform 232 to lift the battery cell A synchronously, so as to position the battery cell A in the vertical direction. The battery cell A is supported by the support part 231 and the lifting part 2321 together, so as to avoid the battery cell A from tilting or falling to the second avoidance space b between two adjacent support parts 231, thereby improving the compatibility of the battery cell processing equipment. Optionally, the bearing driver 237 can be a cylinder. The support platform can be installed on the first fixed seat 233 through a guide rod and a guide sleeve, so that it can move relative to the first fixed seat 233 in the vertical direction under the sliding cooperation of the guide rod and the guide sleeve.

[0069] Please continue to see Figure 2 and Figure 3 As shown, specifically in the embodiment, the transfer clamping assembly 21 and the bearing assembly 23 are arranged at intervals along the second direction, and the transfer drive assembly 22 is used to drive the transfer clamping drive 211 to reciprocate along the second direction, so as to drive the battery cells clamped by the two transfer clamps 212 to move to the multiple support parts 231 of the support platform of the bearing assembly 23. The multiple clamping parts 2121 are arranged at intervals along a third direction perpendicular to the second direction, and the multiple support parts 231 are arranged at intervals along the third direction, and the multiple clamping parts 2121 and the multiple support parts 231 are staggered in the third direction, so that when the two transfer clamps 212 move toward the bearing assembly 23 along the second direction, it can be ensured that each clamping part 2121 of a corresponding transfer clamp 212 can be inserted into the corresponding second avoidance space b, and each support part 231 can be inserted into the corresponding first avoidance space a. Specifically Figure 3 In the embodiment shown, the second direction is the left-right direction, and the third direction is the up-down direction. Optionally, the third direction is parallel to the first direction.

[0070] Specifically in the embodiment, the transport drive assembly 22 includes a second fixed seat 221, a drive plate 222 and a transport drive 223. The second fixed seat 221 is installed on the frame 10, and the transport drive 223 is arranged on the second fixed seat 221, and is connected to the drive plate 222 in a transmission manner to drive the drive plate 222 to move relative to the second fixed seat 221 along the second direction. The transport clamping drive 211 is installed on the drive plate 222 to move synchronously with the drive plate 222 along the second direction. In this way, since the two transport clamps 212 of the transport clamping assembly 21 are connected to the transport clamping drive 211 in a transmission manner, the transport clamping drive 211 is installed on the drive plate 222, so that when the transport drive 223 drives the drive plate 222 to move along the second direction, the drive plate 222 drives the transport clamping drive 211 and the two transport clamps 212 to move along the second direction, so that the battery cell clamped by the clamping portion 2121 of the two transport clamps 212 is transported to the loading station.

[0071] Further, the transport drive assembly 22 also includes a transport screw 224 and a transport screw nut 225. The transport screw 224 is rotatably connected to the second fixed seat 221 around its own axis, and the transport drive 223 is transmission-connected to the transport screw 224 to drive the transport screw 224 to rotate around its own axis. The transport screw nut 225 is threadedly connected to the transport screw 224 and connected to the drive plate 222. Wherein, the self axis of the transport screw 224 is parallel to the above-mentioned second direction. In this way, when it is necessary to drive the transport clamping assembly 21 to move, the transport drive 223 drives the transport screw 224 to rotate around its own axis, thereby driving the transport screw nut 225 and the drive plate 222 connected to the transport screw nut 225 to move along the axial direction of the transport screw 224 (i.e., the second direction), and then drives the transport clamping assembly 21 installed on the drive plate 222 to move along the second direction. Optionally, the transport drive 223 can be a motor. Optionally, the transport screw 224 is installed on the second fixed seat 221 through a bearing seat, so that the transport screw 224 can rotate around its own axis.

[0072] In some embodiments, the transfer device 20 also includes a rotating assembly, and the transfer drive assembly 22 is transmission-connected to the rotating assembly to drive the rotating assembly to move. The rotating assembly is transmission-connected to the transfer clamping drive member 211 to drive the transfer clamping drive member 211 to rotate. In this way, the transfer drive assembly 22 can drive the rotating assembly and the transfer clamping drive member 211 to move, thereby driving the two transfer clamps 212 to clamp and the battery cells clamped therein to move to the loading station. The rotating assembly can drive the transfer clamping drive member 211 to rotate, thereby driving the two transfer clamps 212 to clamp and the battery cells clamped therein to rotate, so as to adjust the orientation of the battery cells by rotation (for example, rotate 180° to prevent the battery cells from being placed in reverse), so that the battery cells can be adapted to be processed at subsequent processing stations, thereby improving the compatibility of the battery cell processing equipment.

[0073] Specifically in the embodiment, the rotating assembly includes a rotating drive member and a rotating seat, and the rotating drive member is installed on the driving plate 222 and is connected to the rotating seat to drive the rotating seat to rotate around the rotating axis parallel to the second direction. The transport clamping drive member 211 is installed on the rotating seat, so that the transport clamping drive member 211 rotates together with the rotating seat, and then drives the two transport clamping claws 212 installed on the transport clamping drive member 211 and the battery core clamped by the clamping portion 2121 of the two transport clamping claws 212 to rotate, so as to adjust the orientation of the battery core by rotation (for example, rotate 180° to prevent the position of the battery core from being reversed), so that the battery core is adapted to be processed in subsequent processing stations, and the compatibility of the battery core processing equipment is improved. Of course, it should be noted that when the battery core does not need to be rotated, the rotating drive member and the rotating seat may not be required. The transport clamping drive member 211 is fixedly connected to the driving plate 222 through a fixed plate, and moves along the second direction with the driving plate 222. Optionally, the rotating drive member can be a rotating cylinder.

[0074] See also Figure 1 and Figure 5 As shown, in an embodiment of the present invention, the transport drive assembly 31 can also drive each clamping assembly 32 to rise and fall in the vertical direction, and the first direction is perpendicular to the vertical direction. In this way, when the battery cell needs to be circulated, the transport drive assembly 31 drives each clamping assembly 32 to move to the top of the corresponding station (loading station or processing station) along the first direction. Then, the transport drive assembly 31 drives each clamping assembly 32 to descend so that each clamping assembly 32 clamps the battery cell on the corresponding station. Then, the transport drive assembly 31 drives each clamping assembly 32 to move to the station (i.e., the processing station) on the downstream side of the corresponding station along the first direction, so that each clamping assembly 32 releases the battery cell to the corresponding station. Finally, the transport drive assembly 31 drives each clamping assembly 32 to rise (to avoid the clamping assembly 32 from colliding with the battery cell when returning along the first direction), and moves along the first direction and returns to the corresponding station, preparing for the next transport of the battery cell.

[0075] In some embodiments, the transport device 30 further includes a linkage assembly 33, which includes a fixed bracket 331, a first drive rod 332, and a second drive rod 333. The fixed bracket 331 is in transmission connection with the transport drive assembly 31, so as to be driven to reciprocate along the first direction by the transport drive assembly 31. The first drive rod 332 and the second drive rod 333 are disposed on the fixed bracket 331, and at least one of them can be controlled to move relative to the fixed bracket 331 along the first direction.

[0076] Each clamping assembly 32 includes a first clamping jaw 321 and a second clamping jaw 322 arranged relatively along a first direction, the first clamping jaw 321 of each clamping assembly 32 is connected to a first driving rod 332, and the second clamping jaw 322 of each clamping assembly 32 is connected to a second driving rod 333. In this way, the transport driving assembly 31 drives the fixed bracket 331 to move back and forth along the first direction and the vertical direction, thereby driving each clamping assembly 32 to move synchronously between the corresponding workstation and the workstation downstream of the corresponding workstation. When each clamping assembly 32 moves to the corresponding workstation, at least one of the first driving rod 332 and the second driving rod 333 is controlled to move relative to the fixed bracket 331 along the first direction, so that the first clamping jaw 321 and the second clamping jaw 322 of each clamping assembly 32 are close to each other along the first direction, thereby clamping the corresponding battery cell. When each clamping assembly 32 moves to the downstream side of its corresponding workstation, at least one of the first driving rod 332 and the second driving rod 333 is controlled to move along the first direction relative to the fixed bracket 331, so that the first clamping jaw 321 and the second clamping jaw 322 of each clamping assembly 32 move away from each other along the first direction, thereby releasing the corresponding battery cell.

[0077] It should be noted that, in one embodiment, the first driving rod 332 is configured to be controllably movable along the first direction, and the second driving rod 333 is fixedly connected to the fixed bracket 331, so that by controlling the first driving rod 332 to move along the first direction, the first clamping jaw 321 of each clamping assembly 32 is moved closer to or away from the second clamping jaw 322 along the first direction, thereby clamping or releasing the battery cell. In another embodiment, the first driving rod 332 and the second driving rod 333 are both configured to be controllably movable along the first direction, so that by controlling the first driving rod 332 and the second driving rod 333 to move along the first direction, the first clamping jaw 321 and the second clamping jaw 322 of each clamping assembly 32 are respectively driven to move closer to or away from each other, thereby clamping or releasing the battery cell.

[0078] Specifically in the embodiment, the linkage assembly 33 further includes a first clamping drive member 334 and a second clamping drive member 335. The first clamping drive member 334 is mounted on the fixed bracket 331 and is transmission-connected to the first drive rod 332 to drive the first drive rod 332 to reciprocate along the first direction relative to the fixed bracket 331. The second clamping drive member 335 is mounted on the fixed bracket 331 and is transmission-connected to the second drive rod 333 to drive the second drive rod 333 to reciprocate along the first direction relative to the fixed bracket 331. Optionally, both the first clamping drive member 334 and the second clamping drive member 335 can be cylinders.

[0079] In one embodiment, the handling device 30 also includes a first unloading component 34, which is installed on the fixed bracket 331, and can push the battery cell located at the most downstream processing station (i.e., the processing station farthest from the loading station) downstream when the fixed bracket 331 moves along the first direction, thereby realizing the unloading of the battery cell. In this way, while each clamping component 32 transports the battery cell at the corresponding station to the station on the downstream side of the corresponding station, the first unloading component 34 pushes the battery cell at the most downstream processing station downstream, thereby realizing the unloading of the battery cell. Specifically, the first unloading component 34 includes a first unloading clamp 341 fixedly connected to the fixed bracket 331, and the first unloading clamp 341 is used to push the battery cell at the most downstream processing station downstream. Furthermore, the first material removal component 34 also includes a second material removal clamp 342, and the first material removal clamp 341 and the second material removal clamp 342 are arranged at intervals along the first direction to form a clamping position for clamping the battery cell therebetween, which is used to clamp the battery cell on the most downstream processing station, so that the movement of the battery cell in the process of pushing the battery cell downstream is more stable and reliable. It can be understood that the spacing between the first material removal clamp 341 and the second material removal clamp 342 remains unchanged and is equivalent to the width of the battery cell, so as to keep the battery cell state stable during the process of pushing downstream.

[0080] In another embodiment, the handling device 30 further includes a second unloading assembly, which includes a third unloading jaw and a fourth unloading jaw arranged relatively along the first direction, the third unloading jaw is connected to the first driving rod 332, and the fourth unloading jaw is connected to the second driving rod 333, so that when the first driving rod 332 and the second driving rod 333 drive the first jaw 321 and the second jaw 322 of each clamping assembly 32 to clamp their respective corresponding battery cells, the third unloading jaw and the fourth unloading jaw of the second unloading assembly are also driven to approach each other and clamp the processing station located at the most downstream. battery cells; when each clamping assembly 32 moves along the first direction to the downstream side of its corresponding station after clamping the battery cells, the third and fourth unloading jaws of the second unloading assembly also drive the clamped battery cells to move downstream; when the first driving rod 332 and the second driving rod 333 drive the first and second jaws 321 and 322 of each clamping assembly 32 to release the battery cells, the third and fourth unloading jaws of the second unloading assembly are also driven to move away from each other and release the battery cells, thereby realizing the transportation of the battery cells on the most downstream processing station to the downstream, and then realizing unloading.

[0081] In some embodiments, the transport drive assembly 31 includes a transport base plate 317, a loading and moving plate 312, a transport drive member 311, a lifting plate 314 and a lifting drive member 313. The transport base plate 317 is mounted on the frame 10, and the loading and moving plate 312 is movably connected to the transport base plate 317 along a first direction. The transport drive member 311 is disposed on the transport base plate 317 and is transmission-connected to the loading and moving plate 312 to drive the loading and moving plate 312 to move along the first direction. The lifting plate 314 is movably connected to the loading and moving plate 312 in a vertical direction, and the fixed bracket 331 is fixedly connected to the lifting plate 314 to move along the vertical direction with the lifting plate 314. The lifting drive member 313 is disposed on the loading and moving plate 312 and is transmission-connected to the lifting plate 314 to drive the lifting plate 314 to move in the vertical direction. In this way, the transport driving member 311 and the lifting driving member 313 can respectively drive the carrying plate 312 to move in the first direction and the lifting plate 314 to move in the vertical direction, thereby realizing the movement of each clamping assembly 32 in the first direction and the vertical direction. Optionally, the lifting driving member 313 can be a cylinder.

[0082] Optionally, a translation slider is provided on the loading and moving plate 312, and a translation rail 3171 extending longitudinally along the first direction is provided on the transport base plate 317, and the translation slider is slidably connected to the translation rail 3171, so that the loading and moving plate 312 can move along the translation rail 3171 (i.e., the first direction) relative to the transport base plate 317. Of course, in other embodiments, the translation slider can also be provided on the transport base plate 317, and the translation rail 3171 is provided on the loading and moving plate 312, which is not limited here.

[0083] The lifting plate 314 is provided with a lifting slider, and the loading and moving plate 312 is provided with a lifting rail 3121 extending longitudinally in the vertical direction, and the lifting slider is slidably connected to the translation rail 3171, so that the lifting plate 314 can move along the lifting rail 3121 (i.e., in the vertical direction) relative to the loading and moving plate 312. Of course, in other embodiments, the lifting slider can also be provided on the loading and moving plate 312, and the lifting rail 3121 is provided on the lifting plate 314, which is not limited here.

[0084] Specifically in the embodiment, the transport drive assembly 31 also includes a transport screw 315 and a transport screw nut 316. The transport screw 315 is rotatably connected to the transport base plate 317 along its own axis, and is transmission-connected to the transport drive 311 so as to be driven by the transport drive 311 to rotate around its own axis. Among them, the axial direction of the transport screw 315 is parallel to the first direction. The transport screw nut 316 is threadedly connected to the transport screw 315 and is fixedly connected to the loading and moving plate 312 so that the loading and moving plate 312 can move along the axial direction (i.e., the first direction) of the transport screw 315 together with the transport screw nut 316. In this way, the screw pair formed by the transport screw 315 and the transport screw nut 316 is used to drive the loading and moving plate 312 to move along the first direction, thereby driving each clamping assembly 32 to move along the first direction, and realizing the flow of the battery cell between two adjacent stations, which is conducive to ensuring the accurate and reliable flow of the battery cell. Optionally, the transport drive 311 can be a motor.

[0085] See also Figure 1 , Figure 6 and Figure 7 As shown, in an embodiment of the present invention, the battery cell processing equipment further includes a battery cell flattening device 40 disposed on the frame 10, and the battery cell flattening device 40 is arranged corresponding to a processing station to flatten the battery cell on the processing station. It should be noted that, in one embodiment, the battery cell flattening device 40 can be arranged on a processing station adjacent to the loading station to flatten the battery cell transported from the loading station to the processing station.

[0086] The battery cell flattening device 40 includes a support assembly (not shown) and a pressing assembly 41. The support assembly includes a support plate 421 for supporting the battery cell, and the support plate 421 is arranged on the frame 10 and is located at the corresponding processing station. The pressing assembly 41 includes a pressing plate 411 and a pressing drive 412, and the pressing plate 411 is arranged on the frame 10 and is arranged relative to the support plate 421. The pressing plate 411 can move closer to or farther from the support plate 421 to flatten the battery cell on the support plate 421 in the process of the pressing plate 411 approaching the support plate 421. The pressing drive 412 is arranged on the frame 10 and is transmission-connected to the pressing plate 411 to drive the pressing plate 411 to move closer to or farther from the support plate 421. Optionally, the pressing drive 412 can be a cylinder or a motor.

[0087] Among them, the position of the support plate 421 relative to the frame 10 in the fourth direction is adjustable, and the fourth direction is perpendicular to the moving direction of the pressing plate 411, so that the position of the battery cells on the support plate 421 relative to the pressing plate 411 can be adjusted to ensure that the battery cells are located in the center of the pressing plate 411 when the pressing plate 411 flattens the battery cells, so that the battery cells are evenly stressed, avoiding the phenomenon of fish scale patterns on the edges of the battery cells, and improving the product yield.

[0088] It should be noted that in Figure 6 In the illustrated embodiment, the pressing plate 411 is located above the supporting plate 421, and the pressing plate 411 can be moved closer to or farther from the supporting plate 421 in a vertical direction. The fourth direction is a direction perpendicular to the paper surface. Optionally, the fourth direction is perpendicular to the first direction.

[0089] In some embodiments, the battery cell flattening device 40 further includes an adjustment component 422, which includes an adjustment base plate 4221 and an adjustment drive member 4222. The adjustment base plate 4221 is connected to the frame 10, and the support plate 421 is movably connected to the adjustment base plate 4221 along the fourth direction. The adjustment drive member 4222 is disposed on the adjustment base plate 4221 and is in transmission connection with the support plate 421 to drive the support plate 421 to move along the fourth direction, thereby achieving the purpose of adjusting the position of the battery cell on the support plate 421 relative to the pressing plate 411.

[0090] Specifically in the embodiment, the adjustment component 422 also includes an adjustment screw 4225 and an adjustment screw nut 4226. The adjustment screw 4225 is rotatably connected to the adjustment base plate 4221 around its own axis, and the axis of the adjustment screw 4225 is parallel to the fourth direction. The adjustment drive 4222 is transmission-connected to the adjustment screw 4225 to drive the adjustment screw 4225 to rotate around its own axis. The adjustment screw nut 4226 is threadedly connected to the adjustment screw 4225 and connected to the support plate 421 so that the support plate 421 moves along the fourth direction with the adjustment screw nut 4226. In this way, the adjustment drive 4222 drives the adjustment screw 4225 to rotate around its own axis, thereby driving the adjustment screw nut 4226 and the support plate 421 to move along the fourth direction, thereby achieving the purpose of adjusting the position of the battery cell on the support plate 421 relative to the pressure plate 411. Optionally, the adjustment drive 4222 can be a motor.

[0091] Specifically in the embodiment, the adjustment assembly 422 further includes an adjustment rail 4224 and an adjustment slider 4223. The adjustment rail 4224 is fixedly connected to one of the support plate 421 and the rack 10, and extends longitudinally along the fourth direction. The adjustment slider 4223 is fixedly connected to the other of the support plate 421 and the rack 10, and the adjustment slider 4223 is slidably connected to the adjustment rail 4224, thereby realizing that the support plate 421 can move relative to the rack 10 along the fourth direction.

[0092] Specifically in the embodiment, the pressing plate 411 is a hot pressing plate. Optionally, the pressing plate 411 is provided with a heating hole, and the heating hole is used to install a heating tube and a thermal resistor to keep the pressing plate 411 at a set temperature, thereby heating the battery cell during the process of flattening the battery cell, which is conducive to improving the flattening effect.

[0093] Specifically in the embodiment, the support plate 421 is a hot pressing plate. Optionally, the support plate 421 is provided with a heating hole, and the heating hole is used to install a heating tube and a thermal resistor, so that the support plate 421 maintains a stable setting, thereby heating the battery cell when the pressing plate 411 flattens the battery cell, which is conducive to improving the flattening effect.

[0094] It should be noted that, preferably, the pressing plate 411 and the supporting plate 421 can both be hot pressing plates, which is beneficial to improving the flattening effect of the battery cell. Of course, in other embodiments, only one of the pressing plate 411 and the supporting plate 421 can be a hot pressing plate and the other can be a normal temperature plate, which is not limited here.

[0095] Specifically in the embodiment, a blow hole is provided on one side of the pressing plate 411 facing the support plate 421, and the blow hole is used to blow air toward the battery cell between the pressing plate 411 and the support plate 421, so that the pressing plate 411 is separated from the battery cell when the pressing plate 411 rises after flattening the battery cell, and the pressing plate 411 is prevented from being taken away from the battery cell. Furthermore, the pressing plate 411 is also provided with an air inlet hole connected to the blow hole, and the air inlet hole is used to connect to an external air inlet pipeline, so that the gas transported by the air inlet pipeline enters the blow hole through the air inlet hole and is blown toward the battery cell.

[0096] Specifically in the embodiment, an air suction hole is opened on the side of the support plate 421 facing the pressing plate 411, and the air suction hole is used to generate an adsorption force to adsorb the battery cells on the support plate 421 during the air suction process, so that when the pressing plate 411 rises after flattening the battery cells, the pressing plate 411 is separated from the battery cells to prevent the pressing plate 411 from being pulled away from the battery cells.

[0097] Furthermore, the support plate 421 is also provided with an air outlet hole connected to the air intake hole, and the air outlet hole is used to connect to an external air extraction pipeline, so that the air extraction pipeline extracts air through the air intake hole and the air outlet hole, thereby forming a negative pressure to adsorb the battery cell.

[0098] Specifically in the embodiment, the pressing assembly 41 further includes a guide rod 413, and the frame 10 is installed with a first guide sleeve 414. The guide rod 413 is slidably matched with the first guide sleeve 414, and the pressing plate 411 is connected to one end of the guide rod 413. In this way, the pressing plate 411 moves closer to or away from the support plate 421 under the guidance of the guide rod 413, which is conducive to improving the movement accuracy of the pressing plate 411. Furthermore, the end of the guide rod 413 away from the pressing plate 411 has a limiting portion 415, and the limiting portion 415 is used to prevent the guide rod 413 from sliding out of the first guide sleeve 414.

[0099] In an embodiment of the present invention, the battery cell processing equipment further includes a short circuit testing device 50 arranged corresponding to a processing station, for performing a short circuit test on the battery cell.

[0100] The short circuit test device 50 includes a lifting assembly 52 and a first clamping assembly 51. The lifting assembly 52 includes a mounting seat 521, a lifting driving member 522 and an electrode head 523. The mounting seat 521 is connected to the frame 10, and the lifting driving member 522 is installed on the mounting seat 521 and is in transmission connection with the electrode head 523 to drive the electrode head 523 to move. The first clamping assembly 51 includes a first clamping driving member 514 and a clamping plate 511. The first clamping driving member 514 is installed on the frame 10 and is in transmission connection with the clamping plate 511 to drive the clamping plate 511 to move.

[0101] The electrode head 523 and the clamping plate 511 are arranged relative to each other so as to approach or move away from each other during the relative movement of the electrode head 523 and the clamping plate 511, so as to clamp the pole ear of the battery cell located at the corresponding processing station. Specifically, the electrode head 523 and the clamping plate 511 are arranged relative to each other in the vertical direction, the lifting drive 522 drives the electrode head 523 to move in the vertical direction, and the first clamping drive 514 drives the clamping plate 511 to move in the vertical direction, so that the electrode head 523 and the clamping plate 511 are close to or away from each other in the vertical direction. In this way, when it is necessary to perform a short-circuit test on the battery cell, the lifting drive 522 drives the electrode head 523 to rise, and at the same time, the first clamping drive 514 drives the clamping plate 511 to descend, so that the clamping plate 511 presses the pole ear of the battery cell onto the electrode head 523, and the short-circuit test of the battery cell is realized because the electrode head 523 is energized. Optionally, the first clamping drive 514 can be a cylinder.

[0102] Specifically in the embodiment, the lifting assembly 52 also includes a fixing bar 524, which is installed at the driving end of the lifting drive 522 to move in the vertical direction under the drive of the lifting drive 522. The electrode head 523 includes two, two electrode heads 523 are installed on the fixing bar 524, and the position of each electrode head 523 relative to the fixing bar 524 is adjustable. The relative positions of the two electrode heads 523 are adjusted to correspond to the two pole ears of the battery cell respectively, so as to adapt to the spacing between the two pole ears of the battery cells of different specifications, which is conducive to improving the compatibility of the battery cell processing equipment. In this way, when it is necessary to perform a short-circuit test on the battery cell, the lifting drive 522 drives the fixing bar 524 to rise, thereby driving the two electrode heads 523 to rise. At the same time, the first clamping drive 514 drives the clamping plate 511 to descend, so that the clamping plate 511 presses the two pole ears of the battery cell onto the two electrode heads 523 respectively. Since the electrode heads 523 are energized, the short-circuit test of the battery cell is realized.

[0103] Specifically in the embodiment, the first clamping assembly 51 also includes a floating plate 512 and an elastic member 513, and the floating plate 512 is installed at the driving end of the first clamping driver 514 to be driven by the first clamping driver 514 to move in the vertical direction. The clamping plate 511 is arranged on the side of the floating plate 512 facing the electrode head 523, and is movable in the vertical direction relative to the floating plate 512. The elastic member 513 is arranged between the clamping plate 511 and the floating plate 512 to provide a pre-tightening force that makes the clamping plate 511 have a movement tendency in the direction away from the floating plate 512. In this way, in the process of the clamping plate 511 pressing the pole ear of the battery cell to the electrode head 523, the elastic member 513 can play a buffering role to prevent the clamping plate 511 and the electrode head 523 from causing a hard impact on the pole ear of the battery cell and damaging the pole ear. Optionally, the elastic member 513 can be a spring.

[0104] Furthermore, the clamping plate 511 is connected to one end of the first guide rod, and a second guide sleeve is installed on the floating plate 512. The first guide rod is slidably matched with the second guide sleeve, so that the movement of the clamping plate 511 relative to the floating plate 512 is guided by the sliding match between the first guide rod and the second guide sleeve.

[0105] Specifically in the embodiment, the short-circuit test device 50 also includes a second clamping assembly (not shown in the figure), which includes a clamping seat 532 and a second clamping driver 531. The clamping seat 532 can be movably connected to the frame 10 in the vertical direction. The clamping seat 532 can clamp the battery cell located at the corresponding processing station during the movement of the clamping seat 532 in the vertical direction. The second clamping driver 531 is installed on the frame 10 and is transmission-connected with the clamping seat 532 to drive the clamping seat 532 to move in the vertical direction. In this way, before the battery cell is short-circuited, the battery cell is first clamped using the clamping seat 532 to fix the battery cell to prevent the battery cell from being displaced during the process of clamping the pole ear of the battery cell, resulting in the failure of the short-circuit test. Optionally, the second clamping driver 531 can be a cylinder. Furthermore, the clamping seat 532 is fixedly connected to one end of the second guide rod 533, and a third guide sleeve is installed on the frame 10. The second guide rod 533 and the third guide sleeve are slidably matched, and the sliding match between the second guide rod 533 and the third guide sleeve is used to guide the movement of the clamping seat 532 relative to the frame 10.

[0106] It should be noted that, in one embodiment, the short-circuit test device 50 is arranged at a processing station downstream of the battery cell flattening device 40. In other embodiments, the battery cell flattening device 40 may also include a short-circuit test device 50, and the lower pressing component 41 of the battery cell flattening device 40 first flattens the battery cell at the processing station, and then the short-circuit test device 50 performs a short-circuit test on the flattened battery cell (that is, the flattening and short-circuit tests are completed at the same station). It should also be noted that when the battery cell flattening device 40 includes the short-circuit test device 50, the lower pressing component 41 of the battery cell flattening device 40 can be used to press the battery cell to prevent the battery cell from moving, so at this time the short-circuit test device 50 does not need the above-mentioned second pressing component. In this embodiment, the first clamping driver 514 of the first clamping assembly 51 is not directly mounted on the frame 10, but is fixedly arranged relative to the pressing plate 411 (for example, mounted on the pressing plate 411), so that when the pressing driver 412 drives the pressing plate 411 to press down, the first clamping assembly 51 and the pressing plate 511 can be driven to descend. After the pressing plate 411 flattens the battery cell, the first clamping assembly 51 drives the pressing plate 511 to continue to descend, thereby pressing the tab of the battery cell against the electrode head 523, thereby realizing the short circuit test of the battery cell, and reducing the stroke of the first clamping assembly 51, which is conducive to improving production efficiency.

[0107] In an embodiment of the present invention, the battery cell processing equipment further includes a visual inspection device 60 arranged corresponding to a processing station, and the visual inspection device 60 is used to perform visual inspection on the battery cell on the corresponding processing station.

[0108] In some embodiments, the visual inspection device 60 includes an inspection camera 61 installed on the frame 10. The inspection camera 61 is located above the corresponding processing station and is used to perform visual inspection on the battery cells on the corresponding processing station.

[0109] Specifically in the embodiment, the visual inspection device 60 also includes a support block 62 and a third clamping assembly 64. The support block 62 is mounted on the frame 10 to support the battery cell on the corresponding processing station. The third clamping assembly 64 includes a clamp 642 and a third clamping driver 641, the third clamping driver 641 is mounted on the frame 10, and the clamp 642 is mounted on the driving end of the third clamping driver 641, so that the third clamping driver 641 drives the clamp 642 to move, thereby pressing the battery cell against the support block 62 to prevent the battery cell from expanding freely and affecting the visual inspection accuracy. Optionally, the third clamping driver 641 may be a cylinder. Optionally, at least the portion of the clamp 642 corresponding to the battery cell pole ear is light-transmissive, so that it does not affect the visual inspection of the battery cell pole ear portion by the visual inspection camera 61 while not affecting the clamping of the battery cell. Specifically, the portion of the clamp 642 corresponding to the battery cell pole ear is an embedded glass clamp 643.

[0110] Specifically in the embodiment, the support block 62 may be a light-transmitting support block 62. A light source 63 is installed below the support block 62 to illuminate the battery cell through the support block 62, which is beneficial to improve the detection accuracy of the detection camera 61. Optionally, the material of the support block 62 may be glass, so that the support block 62 is light-transmitting.

[0111] Specific to Figure 6 In the illustrated embodiment, the cell processing equipment includes three processing stations, which are a flattening station, a short circuit test station, and a visual inspection station. The flattening station, the short circuit test station, and the visual inspection station are arranged in sequence from upstream to downstream along the first direction. The cell flattening device 40 is arranged at the flattening station, the short circuit test device 50 is arranged at the short circuit test station, and the visual inspection device 60 is arranged at the visual inspection station.

[0112] Optionally, the battery cell processing equipment also includes a support plate 70, which is mounted on the frame 10 and has a first support area located at the short-circuit test station, and the first support area is used to support the battery cell at the short-circuit test station. It is understandable that the first support area does not cover the portion between the electrode head 523 and the clamping plate 511 to avoid interfering with the electrode head 523 and the clamping plate 511 to clamp the battery cell's tab. Furthermore, the support plate 70 also has a second support area located between the loading station and the flattening station, between the flattening station and the short-circuit test station, and between the short-circuit test station and the visual inspection station, which is used to support the battery cells passing between the corresponding stations to prevent the battery cells from falling during the transportation process of the transportation device 30.
