After the dicing mechanism 23 finishes dicing the battery piece, the first translation module 221 drives the transfer platform 223 to move towards the output mechanism 24 until the battery piece reaches the upper part of the feeding end of the output mechanism 24.

Then, the lift module 222 drives the transfer platform 223 to a low position. So that the battery pieces adsorbed on the transfer platform 223 fall onto the feed end of the output mechanism 24.

As shown in fig. 11, in some embodiments, the battery cells are divided into two battery cell segments. The suction assembly 224 includes two suction plates 2241 disposed side by side, and a scribe avoidance gap 2242 corresponding to a position of the battery piece to be diced is formed between the two suction plates 2241, and an extending direction of the scribe avoidance gap 2242 is parallel to a moving direction (an arrow direction in fig. 11) of the transfer platform 223.

When the first translation module 221 moves the battery piece adsorbed on the adsorption component 224 to the lower side of the dicing mechanism 23. The dicing mechanism 23 performs dicing on the battery piece along the dicing avoidance gap 2242, thereby dividing the battery piece into two battery piece pieces. The two battery pieces are respectively adsorbed on one adsorption plate 2241.

As shown in fig. 12 to 13, the dicing mechanism 23 optionally includes a second translation module 231, a first mounting bracket 232, a slot laser 233, a heating laser 234, and a cooling assembly 235.

The first mounting bracket 232 is connected to the driving end of the second translation module 231, and the slotted laser 233, the heating laser 234, and the cooling assembly 235 are all position-adjustably mounted on the first mounting bracket 232. The second translation module 231 is used for driving the first mounting bracket 232 to translate perpendicular to the moving direction of the transfer mechanism 22, so as to translate the slotting laser 233, the heating laser 234 and the cooling component 235 to the position of the dicing station above the battery piece to be diced. The slotting laser 233 is used for forming a splitting slot on the surface of the battery piece, the heating laser 234 is used for heating the battery piece along the extending direction of the splitting slot, and the cooling component 235 is used for cooling the heated battery piece, so that the battery piece is contracted and then split along the splitting slot, and two battery piece splitting pieces are obtained.

As known to those skilled in the art, in order to facilitate the subsequent processing steps to perform the processing on the battery piece, after the dicing of the battery piece is completed, the separation of the two battery piece pieces obtained by dicing is required, so that the distance between the two battery piece pieces meets the predetermined requirement.

In order to implement automatic separation of the two battery pieces, as shown in fig. 14 to 16, the output mechanism 24 may alternatively include a first conveying section 241 and a second conveying section 242 arranged side by side at intervals, wherein: the transfer mechanism 22 transfers the diced battery piece 101 and the battery piece 102 to the first conveying section 241 and the second conveying section 242, respectively. The first conveying section 241 and the second conveying section 242 output the battery piece segments 101 and 102 simultaneously.

In particular, as shown in fig. 15, the interval a between the feeding end of the first conveying section 141 and the feeding end of the second conveying section 142 is smaller than the interval b between the discharging end of the first conveying section 141 and the discharging end of the second conveying section 142. That is, the distance between the first conveying section 141 and the second conveying section 142 gradually increases in the output direction of the output mechanism 14 (as in the arrow direction in fig. 15). By the arrangement, the distance between the battery piece fragments 101 and 102 can be gradually increased, so that automatic separation of the battery piece fragments 101 and 102 is completed.

In order to improve the dicing efficiency of the dicing apparatus 2, as shown in fig. 11, the transferring mechanism 22 may optionally include two transferring platforms 223, and the two transferring platforms 223 alternately acquire the battery pieces from the input mechanism 21, transfer the battery pieces to the lower part of the dicing mechanism 23, and transfer the battery pieces to the output mechanism 24 under the driving of the corresponding first translation module 221 and lifting module 222.

As shown in fig. 11 and 14, alternatively, the input mechanisms 21 are arranged in two groups side by side, the output mechanisms 24 are arranged in two groups side by side, and two adsorption assemblies 224 are arranged on the transfer platform 223 side by side, where each adsorption assembly 224 corresponds to one group of input mechanisms 21 and one group of output mechanisms 24. The two sets of input mechanisms 21 synchronously input two battery pieces to be diced. The two adsorption assemblies 224 respectively lift up from the corresponding input mechanisms 21 and adsorb one battery piece. After dicing, each suction unit 224 transfers the two battery pieces obtained by dicing to the corresponding output mechanism 24.

By the arrangement, synchronous scribing of two battery slices which are input side by side can be achieved, and therefore scribing efficiency of the scribing device 2 is further improved.

As shown in fig. 17 to 19, optionally, the drying device 3 includes a conveying mechanism 31 and a drying mechanism 32, wherein:

the conveying mechanism 31 includes a first conveying belt 311 and a second conveying belt 312 disposed at a side-by-side interval, the first conveying belt 311 and the second conveying belt 312 being configured to synchronously convey the first battery cell 101 and the second battery cell 102 formed by the same battery cell dicing, wherein:

the first battery cell 101 is located on the first conveyor belt 311, the second battery cell 102 is located on the second conveyor belt 312, and the sides of the first battery cell 101 and the second battery cell 102 that are close to each other (i.e., the side 101a of the first battery cell 101 and the side 102a of the second battery cell 102 within the dashed line frame in fig. 19) are dicing sides formed by dicing.

The drying mechanism 32 is located above the conveying paths of the first conveying belt 311 and the second conveying belt 312, and the drying mechanism 32 is used for drying the dicing sides of the first battery cell 101 and the second battery cell 102.

It can be seen that, through the cooperation of the conveying mechanism 31 and the drying mechanism 32, the drying device 3 realizes the synchronous drying of the two battery piece fragments, and particularly, the drying mechanism 32 only performs the local drying of the mutually adjacent scribing sides of the two battery piece fragments, thereby reducing the drying energy consumption.

As shown in fig. 17 and 18. Optionally, the drying mechanism 32 includes a second mounting bracket 321 and a drying assembly 322, wherein: the drying assembly 322 is mounted on the second mounting bracket 321. The drying assembly 322 is located above the first conveyor belt 311 and the second conveyor belt 312, and is located between the first conveyor belt 311 and the second conveyor belt 312, and the drying assembly 322 is used for heating the dicing sides of the first battery cell 101 and the second battery cell 102.

Optionally, at least two drying assemblies 322 are mounted on the second mounting bracket 321 along the conveying direction of the first conveying belt 311 and the second conveying belt 312, and the at least two drying assemblies 322 sequentially provide drying heat energy for the scribing sides of the passing first battery split piece 101 and the second battery split piece 102.

By installing more than two drying assemblies 322 in the conveying direction of the first conveying belt 311 and the second conveying belt 312, more than two drying treatments of the dicing sides of the first battery piece 101 and the second battery piece 102 are realized, thereby further ensuring the drying effect.

As shown in fig. 20 to 23, the drying assembly 322 may include a heating chamber 323, an air inlet portion 324, and a heating portion 325, wherein: an air flow channel 326 is arranged in the heating chamber 323, and a plurality of air outlet holes 327 communicated with the air flow channel 326 are arranged at the bottom of the heating chamber 323. The air inlet portion 324 is in communication with the air flow channel 326, and the air inlet portion 324 is configured to introduce external air into the air flow channel 326 and drive the air to flow in the air flow channel 326. The heating portion 325 is disposed in the heating chamber 323, the heating portion 325 is configured to heat the gas in the gas flow channel 326, and the heated gas is blown out downwards through the gas outlet holes 327, so as to dry the dicing sides of the first and second battery pieces 101 and 102.

As shown in fig. 22 and 23, alternatively, a plurality of baffles 328 arranged in a staggered manner in the vertical direction are provided on two opposite inner walls of the heating chamber 323, and the plurality of baffles 328 form a circuitous air flow channel 326 in the heating chamber 323.

By forming the air flow passage 326 with a roundabout bend in the heating chamber 323, the heating stroke of the heating portion 325 to the air entering into the heating chamber 323 can be effectively prolonged, thereby ensuring that the drying temperature of the hot air blown to the dicing sides of the first and second battery pieces 101 and 102 can satisfy the drying requirement.

As shown in fig. 24, alternatively, two air flow passages 326 are symmetrically provided in the heating chamber 323, and the heating portion 325 is provided between the two air flow passages 326, wherein one air flow passage 326 is close to the first conveyor belt 311, and hot air blown from the air flow passage 326 is used for drying the dicing side edges of the battery piece-pieces 101. The other air flow channel 326 is adjacent to the second conveyor belt 312, and the hot air blown from the air flow channel 326 is used to dry the dicing side of the battery piece 102.

By arranging two symmetrical air flow channels 326 in the heating chamber 323 and arranging the heating part 324 between the two air flow channels 326, the consistency of the air quantity and the temperature of the hot air blown to the scribing side edge of the first battery piece 101 and the scribing side edge of the second battery piece 102 is ensured, and finally the consistency of the drying speed of the drying device 3 to the scribing side edge of the first battery piece 101 and the scribing side edge of the second battery piece 102 is ensured.

As shown in fig. 1, optionally, the battery slice splitting apparatus in the embodiment of the present utility model further includes a blanking device 4 disposed at a subsequent stage of the drying device 3. The feeding end of the discharging device 4 is in butt joint with the discharging end of the drying device 3, and the discharging device 4 is used for collecting the dried battery piece fragments output by the drying device 3.

Through setting up unloader 4 to dock unloader 4's pan feeding end and drying device 3's discharge end, make unloader 4 can implement the automatic receipts material of the battery piece burst after the completion stoving to drying device 3 output.

As shown in fig. 25 and 26, the discharging device 4 includes a discharging mechanism 41 and a jacking mechanism 42, wherein:

the blanking mechanism 41 comprises a third mounting bracket 411 and at least two sliding support plates 412 arranged on the third mounting bracket 411 layer by layer along the vertical direction, each sliding support plate 412 is provided with a blanking component 413, and each sliding support plate 413 is configured to be capable of horizontally sliding on the third mounting bracket 411 independently so as to drive the corresponding blanking component 413 to be horizontally shifted between a respective receiving position and a discharging position.

The lifting mechanism 42 is used for lifting the blanking assembly 413 located at the receiving position away from the sliding support plate 412, so that the blanking assembly 413 is in butt joint with the discharging end of the drying device 3.

The lifting mechanism 42 is further used for placing the blanking assembly 413 back onto the sliding support plate 412 after the blanking assembly 413 finishes receiving the material.

Taking the example of the blanking device 4 with three sliding support plates 412 in the embodiment of fig. 25, an optional material receiving process is as follows:

when the material receiving is not started, the three sliding support plates 412 are far away from the jacking mechanism 42, the discharging assemblies 413 on the sliding support plates 412 are positioned at the respective discharging positions, and the discharging assemblies 413 are empty.

Starting material collection:

first, one of the slide support plates 412 is controlled to move toward the jacking mechanism 42 until the discharging assembly 413 on the slide support plate 412 is switched to its receiving position.

The lifting mechanism 42 lifts the discharging assembly 413 located at the receiving position away from the sliding support plate 412 to be in butt joint with the discharging end of the drying device 3.

After the discharging component 413 at the receiving station receives the battery piece from the drying device 3, the lifting mechanism 42 descends to return to the original position, so that the discharging component 413 receives the battery piece to return to the corresponding sliding support plate 412.

Then, the slide support plate 412 carrying the blanking assembly 413 of the full-cell piece is moved away from the jacking mechanism 42 until the blanking assembly 413 of the full-cell piece is switched to its discharging position. The battery piece in the discharging component 413 of the fully collected battery piece is taken out, and at the same time, the other sliding support plate 412 is controlled to move towards the jacking mechanism 42 until the discharging component 413 on the other sliding support plate 412 is switched to the material collecting position.

Therefore, the blanking assemblies 413 on each sliding support plate 412 can alternately move to the corresponding material receiving position, so that the jacking mechanism 42 can timely jack the blanking assemblies 413 to be received to the material receiving station, and the condition that the material receiving station waits due to the shortage of the blanking assemblies 413 is prevented. In addition, when the discharging assembly 413 fully packed with the battery piece fragments moves to the corresponding discharging position, the battery piece fragments are taken out. Therefore, the battery piece slice taking-out operation and the material receiving operation at the material receiving station can be synchronously implemented without interference.

As shown in fig. 26, the blanking assembly 413 may optionally include a base plate 414 and a material frame 415, wherein the base plate 414 is carried on the sliding support plate 412 and the material frame 415 is disposed on the base plate 414.

When the blanking member 413 is switched to the receiving position, the lifting mechanism 42 lifts the bottom plate 414 of the blanking member 413 upward to lift the blanking member 413 off the sliding support plate 412.

After the material rack 415 of the discharging assembly 413 finishes receiving the material, the lifting mechanism 42 descends to return to the position so as to put the bottom plate 414 of the discharging assembly 413 back onto the sliding support plate 412.

In order to implement the synchronous collection and discharging of the two battery piece fragments outputted by the drying device 3 side by side, as shown in fig. 26, alternatively, the material racks 415 are arranged in pairs, and each pair of material racks 415 is used for synchronously collecting the two battery piece fragments conveyed by the drying device 3 side by side. The blanking assembly 413 in the embodiment of fig. 26 is provided with two pairs of material holders 415.

Alternatively, as shown in fig. 26, the bottom of the rack 415 is configured to be inclined downward. By setting the bottom of the rack 415 to be inclined downward, the collected battery piece fragments can be held in the rack 415, preventing the battery pieces from slipping out of the rack 415.

As shown in fig. 25, alternatively, the jacking mechanism 42 includes a jacking driving portion 421 and a jacking plate 422, wherein: the lifting plate 422 is connected to a driving end of the lifting driving portion 421, and the lifting driving portion 421 is used for driving the lifting plate 422 to lift.

When the discharging component 413 is switched to the material receiving position, the lifting driving part 421 drives the lifting plate 422 to lift up, so that the lifting plate 422 lifts the discharging component 413 away from the sliding supporting plate 412 until the material component 413 reaches the material receiving station.

After the discharging assembly 413 is fully filled with the battery pieces, the lifting driving part 421 drives the lifting plate 422 to descend and return to the original position, so that the lifting plate 422 returns the discharging assembly 413 fully filled with the battery piece to the corresponding sliding supporting plate 412.
