The battery core processing equipment is provided with a feeding station and at least two processing stations which are sequentially arranged along a first direction. The transfer device 20 is disposed on the rack 10, and is configured to receive the battery cell and transfer the battery cell to the feeding station. The handling device 30 comprises a handling drive assembly 31 (see fig. 5) and at least two gripping assemblies 32 (see fig. 5). The material loading station and each processing station are correspondingly provided with a clamping assembly 32. The carrying driving assembly 31 is disposed on the frame 10 and is in transmission connection with each of the clamping assemblies 32 to drive each of the clamping assemblies 32 to synchronously reciprocate along the first direction.

In the process that the carrying driving assembly 31 drives each clamping assembly 32 to synchronously reciprocate along the first direction, each clamping assembly 32 can clamp the cell of the corresponding feeding station or processing station and carry the cell to the processing station located at the downstream side of the corresponding feeding station or processing station.

The battery cell processing equipment is provided with a feeding station and at least two processing stations, and the battery cell processing equipment is sequentially arranged along a first direction at intervals. When the battery core processing is performed, the transferring device 20 receives the battery core input from the upstream, transfers the battery core to the loading station, and then continuously transfers the battery core to the processing station. Meanwhile, under the driving of the carrying driving assembly 31 of the carrying device 30, each clamping assembly 32 synchronously reciprocates synchronously along the first direction, so that each clamping assembly 32 clamps and takes the electric core on the corresponding feeding station or the corresponding processing station, and carries the clamped electric core to the processing station located at the downstream side of the corresponding feeding station or the corresponding processing station, thereby realizing that the electric core on the feeding station sequentially flows to each downstream processing station. Compared with the prior art, the battery cores positioned on the processing stations can be processed simultaneously, the rhythm of the battery core circulation is compact, the production efficiency is improved, the equipment structure is compact, and the occupied space is saved. It should be noted that, specifically, in the embodiment shown in fig. 1, the first direction is a left-right direction.

Referring to fig. 2 and 3, in an embodiment of the present invention, the transferring device 20 includes a transferring clamping assembly 21 and a transferring driving assembly 22. Transfer gripper assembly 21 comprises a transfer gripping drive 211 and two transfer jaws 212 drivingly connected to transfer gripping drive 211. Each of the transfer jaws 212 has a plurality of grip portions 2121 arranged at intervals in sequence, and a first space a is formed between each adjacent two grip portions 2121. The transfer clamping drive 211 is used to drive the clamping portions 2121 of the two transfer jaws 212 to clamp or unclamp the cell, that is, the transfer clamping drive 211 can drive the two transfer jaws 212 to close each other, so as to clamp the cell with the clamping portions 2121 of the two transfer jaws 212; the transfer gripper drive 211 can drive the two transfer jaws 212 to open from each other, so that the clamping portions 2121 of the two transfer jaws 212 release the cell.

Transport drive assembly 22 and transport and press from both sides tight driving piece 211 transmission and be connected to the tight driving piece 211 of drive transport clamp moves to drive two transport clamping jaws 212 and move to the material loading station, and then can make the clamping part 2121 of two transport clamping jaws 212 loosen electric core under the drive of transporting tight driving piece 211, realize transporting electric core to the material loading station.

In this manner, when transferring a cell, first, the transfer drive assembly 22 drives the transfer clamping drive 211 to move to the receiving position for receiving the cell, and the transfer clamping drive 211 drives the two transfer clamping jaws 212 to close each other, so that the cell is clamped by the clamping portions 2121 of the two transfer clamping jaws 212. The transfer drive assembly 22 then drives the transfer clamp drive 211 to move towards the loading station until the cell clamped by the two transfer jaws 212 moves to the loading station. Then, the transfer clamping driving member 211 drives the two transfer clamping jaws 212 to open each other, so as to release the battery core to the feeding station. Alternatively, the transfer clamp drive 211 may be a jaw cylinder.

In practical production, the blanking clamping jaws clamp the wound battery cell on the winding device and blank the battery cell to a receiving position. It should be noted that the blanking clamping jaw is also comb-shaped. Each transfer clamping jaw 212 is designed to have a plurality of clamping parts 2121 arranged at intervals in sequence, and a first avoiding space a is formed between every two adjacent clamping parts 2121, so that comb teeth of the comb-shaped blanking clamping jaw can be avoided by the first avoiding space a between every two adjacent clamping parts 2121 when the cell is clamped at the bearing position, and the cell can be smoothly clamped on the blanking clamping jaw. After the cell is clamped by the clamping portions 2121 of the two transfer clamping jaws 212, the cell is released by the blanking clamping jaws, so that the cell is received. So, two transport clamping jaws 212 of transporting centre gripping subassembly 21 can directly be on the unloading clamping jaw centre gripping electric core to avoided needing to set up one in accepting the position and accepted the platform, the unloading clamping jaw is placed electric core on should accepting the platform, transports two transport clamping jaws 212 of centre gripping subassembly 21 and gets electric core on accepting the platform clamp, simplified the action process of transporting electric core, be favorable to improving production efficiency.

Furthermore, one side of each transfer clamping jaw 212 facing the other transfer clamping jaw 212 is provided with a clearance groove 214 penetrating through each clamping portion 2121 along a predetermined direction, and the clearance grooves 214 on the two transfer clamping jaws 212 are correspondingly arranged. Preferably, the predetermined direction is perpendicular to the arrangement direction of the plurality of clamping portions 2121 on the transfer clamping jaw 212. Each transfer jaw 212 may be provided with one or more clearance slots 214. So, when accepting electric core, two transport the broach of the unloading clamping jaw that is comb form and insert and avoid the position in keeping away groove 214 on the clamping jaw 212 to the realization is to the switching-over centre gripping of electric core.

In some embodiments, the transferring device 20 further includes a carrying assembly 23, and the carrying assembly 23 includes a first fixing seat 233 disposed on the frame 10 and a supporting platform disposed on the first fixing seat 233. The supporting table has a plurality of supporting portions 231 which are used for supporting the battery cell and are sequentially arranged at intervals, and a second avoiding space b is formed between every two adjacent supporting portions 231. In the process that the transferring driving assembly 22 drives the transferring clamping driving element 211 to move toward the loading station, the plurality of clamping portions 2121 corresponding to one transferring clamping jaw 212 can be inserted into the corresponding second avoiding space b (meanwhile, the plurality of supporting portions 231 can be inserted into the corresponding first avoiding space a), so that the battery cell can be released onto the plurality of supporting portions 231.

In one embodiment, the support table is fixed relative to the first fixing base 233, i.e. the support table does not have a lifting function in the vertical direction. In this embodiment, the supporting assembly 23 further includes a positioning driving member 234 and a positioning platform 232, wherein the positioning driving member 234 is mounted on the first fixing seat 233 and is in transmission connection with the positioning platform 232 to drive the positioning platform 232 to move up and down relative to the supporting platform. The positioning platform 232 has a plurality of jacking portions 2321 arranged at intervals in sequence, and each jacking portion 2321 is located the corresponding second clearance space b, so that in the process that the positioning platform 232 rises relative to the supporting table, the plurality of jacking portions 2321 jack up and support the electric core on the plurality of supporting portions 231. In this way, the plurality of lifting portions 2321 of the positioning platform 232 lift up the electric cores on the plurality of supporting portions 231, so as to position the electric cores in the vertical direction, so that the clamping assembly 32, corresponding to the loading station, of the carrying device 30 carries the electric cores on the plurality of lifting portions 2321 to the processing station on the downstream side of the loading station. Alternatively, the positioning drive 234 may be a pneumatic cylinder.

It should be noted that, when a small-sized battery cell is released onto the supporting table, due to the small size of the battery cell, only one supporting portion 231 can support the battery cell, so that the battery cell is easily inclined or dropped to the second avoiding space b between two adjacent supporting portions 231, and the battery cell processing equipment cannot be compatible with the small-sized battery cell. In order to solve the problem that the small-sized battery cells cannot be accommodated, referring to fig. 4, in another embodiment, the bearing assembly 23 further includes a bearing driving member 237, a positioning driving member 234 and a positioning platform 232, the support platform is movable in the vertical direction relative to the first fixing base 233, and the bearing driving member 237 is mounted on the first fixing base 233 and is in transmission connection with the support platform to drive the support platform to move (i.e., lift) in the vertical direction. The positioning driving member 234 is mounted on the supporting platform and is in transmission connection with the positioning platform 232 to drive the positioning platform 232 to ascend and descend relative to the supporting platform. The positioning platform 232 has a plurality of jacking portions 2321 arranged at intervals in sequence, and each jacking portion 2321 is located in the corresponding second clearance space b. The positioning platform 232 can move to the top surface of each jacking portion 2321 and the top surface of each supporting portion 231 to be flush under the driving of the positioning driving member 234. So, jacking portion 2321 of positioning platform 232 can rise to the top surface parallel and level with supporting part 231 under the drive of location driving piece 234 to usable supporting part 231 supports electric core a jointly with jacking portion 2321, then bears driving piece 237 drive supporting bench and positioning platform 232 and carries out the jacking to electric core a in step, thereby fixes a position electric core a in the vertical direction. Utilize supporting part 231 and jacking portion 2321 to support electric core a jointly to avoided electric core a to the second between two adjacent supporting parts 231 to keep away a space b slope or drop, promoted electric core processing equipment's compatibility. Alternatively, the carrier drive 237 may be a pneumatic cylinder. The support table may be installed at the first fixing base 233 through a guide bar and a guide bush so as to be movable in a vertical direction with respect to the first fixing base 233 by a sliding fit of the guide bar and the guide bush.

With reference to fig. 2 and fig. 3, in an embodiment, the transferring clamping assemblies 21 and the carrying assembly 23 are arranged at intervals along the second direction, and the transferring driving assembly 22 is configured to drive the transferring clamping driving member 211 to reciprocate along the second direction, so as to drive the electric cores clamped by the two transferring clamping jaws 212 to move to the plurality of supporting portions 231 of the supporting platform of the carrying assembly 23. The plurality of clamping portions 2121 are arranged at intervals along a third direction perpendicular to the second direction, the plurality of supporting portions 231 are arranged at intervals along the third direction, and the plurality of clamping portions 2121 and the plurality of supporting portions 231 are arranged at intervals along the third direction, so that each clamping portion 2121 of the corresponding transfer jaw 212 can be ensured to be inserted into the corresponding second space b when the two transfer jaws 212 move towards the bearing assembly 23 along the second direction, and each supporting portion 231 can be inserted into the corresponding first space a. Specifically, in the embodiment shown in fig. 3, the second direction is a left-right direction, and the third direction is an up-down direction. Optionally, the third direction is parallel to the first direction.

Specifically, in the embodiment, the transfer driving assembly 22 includes a second fixing seat 221, a driving plate 222 and a transfer driving member 223. The second fixing seat 221 is mounted on the frame 10, and the transfer driving member 223 is disposed on the second fixing seat 221 and is in transmission connection with the driving plate 222 to drive the driving plate 222 to move along the second direction relative to the second fixing seat 221. A transfer clamp drive 211 is mounted to the drive plate 222 for synchronous movement with the drive plate 222 in the second direction. Thus, since the two transferring clamping jaws 212 of the transferring clamping assembly 21 are connected to the transferring clamping driving element 211 in a transmission manner, the transferring clamping driving element 211 is installed on the driving plate 222, so that when the transferring driving element 223 drives the driving plate 222 to move along the second direction, the driving plate 222 drives the transferring clamping driving element 211 and the two transferring clamping jaws 212 to move along the second direction, so as to transfer the battery cell clamped by the clamping portions 2121 of the two transferring clamping jaws 212 to the feeding station.

Further, the transfer drive assembly 22 further includes a transfer screw 224 and a transfer screw nut 225. The transfer screw 224 is rotatably connected to the second fixing seat 221 around its axis, and the transfer driving member 223 is in transmission connection with the transfer screw 224 to drive the transfer screw 224 to rotate around its axis. A transfer screw nut 225 is threadably connected to the transfer screw 224 and is connected to the drive plate 222. Wherein the axis of the transfer screw 224 is parallel to the second direction. Thus, when the transfer clamping assembly 21 needs to be driven to move, the transfer driving member 223 drives the transfer screw rod 224 to rotate around the axis thereof, so as to drive the transfer screw rod nut 225 and the driving plate 222 connected with the transfer screw rod nut 225 to move along the axis direction (i.e. the second direction) of the transfer screw rod 224, and further drive the transfer clamping assembly 21 mounted on the driving plate 222 to move along the second direction. Alternatively, transfer drive 223 may be a motor. Optionally, the transfer screw 224 is mounted on the second fixing seat 221 through a bearing seat, so that the transfer screw 224 can rotate around its axis.

In some embodiments, transfer device 20 further includes a rotating assembly, and transfer drive assembly 22 is drivingly connected to the rotating assembly for driving movement of the rotating assembly. The rotating assembly is in transmission connection with the transferring clamping driving member 211 to drive the transferring clamping driving member 211 to rotate. In this way, the transfer driving assembly 22 can drive the rotating assembly and the transfer clamping driving member 211 to move, so as to drive the two transfer clamping jaws 212 and the battery cells clamped by the two transfer clamping jaws to move to the feeding station. The rotating assembly can drive the transferring and clamping driving piece 211 to rotate, so that the two transferring clamping jaws 212 and the electric core clamped by the transferring clamping jaws are driven to rotate, the position of the electric core is adjusted through rotation (for example, the electric core is rotated by 180 degrees, the position of the electric core is prevented from being reversed), the electric core is suitable for being processed on subsequent processing stations, and the compatibility of electric core processing equipment is improved.

In one embodiment, the rotating assembly includes a rotating driving member and a rotating base, the rotating driving member is mounted on the driving plate 222 and is in transmission connection with the rotating base to drive the rotating base to rotate around a rotating axis parallel to the second direction. Transport and press from both sides tight driving piece 211 and install on this rotates the seat to make transport press from both sides tight driving piece 211 and rotate along with rotating the seat together, and then drive two transport clamping jaws 212 of installing on transporting tight driving piece 211 and by the tight electric core rotation of clamping part 2121 clamp of two transport clamping jaws 212, with the position (for example rotatory 180, prevent that the position of electric core from putting the contrary) through rotating the adjustment electric core, make electric core adaptation process on follow-up each processing station, improve electric core processing equipment's compatibility. Of course, it should be noted that, when the electric core does not need to be rotated, the rotary driving element and the rotary seat may not be needed, and the transfer clamping driving element 211 is fixedly connected to the driving plate 222 through the fixing plate and moves along the second direction together with the driving plate 222. Alternatively, the rotary drive may be a rotary cylinder.

Referring to fig. 1 and 5, in the embodiment of the invention, the carrying driving assembly 31 can also drive each clamping assembly 32 to move up and down along a vertical direction, where the first direction is perpendicular to the vertical direction. In this way, when the cells need to be circulated, the carrying driving assembly 31 drives each clamping assembly 32 to move to the upper side of the corresponding station (loading station or processing station) along the first direction.
