For example, after the conveying mechanism inputs the battery pieces, the handling robot picks up the battery pieces and carries them to the scribing station. After scribing, the handling robot picks up the battery piece splits formed by scribing and carries them to the drying station. After drying, the handling robot picks up the dried battery piece splits and carries them to the material receiving device or the next processing station.

[0085] The existing battery piece slicing device has the problem that a handling manipulator needs to implement multiple picking and handling of the battery piece, which is easy to cause damage to the battery piece.

[0086] In order to solve the above-mentioned problems of the existing battery piece slicing device, the present application provides a battery piece slicing device which can greatly reduce the number of picking and handling of the battery piece, thereby reducing the risk of damage to the battery piece.

[0087] As Figure 1 and Figure 9As shown, the battery piece slicing device in the embodiment of the present application comprises a feeding device 1, a slicing device 2 and a drying device 3, wherein:

[0088] The feeding device 1 is configured to feed the battery piece to be sliced to the slicing device 2.

[0089] The slicing device 2 comprises an input mechanism 21, a transfer mechanism 22, a slicing mechanism 23 and an output mechanism 24, wherein: the transfer mechanism 22 is configured to reciprocate between the input mechanism 21 and the output mechanism 24, and the slicing mechanism 23 is located above the movement path of the transfer mechanism 22. The input mechanism 21 is configured to receive the battery piece fed by the feeding device 1 and to transport the battery piece towards the transfer mechanism 22. The transfer mechanism 22 is configured to transfer the battery piece from the input mechanism 21 to below the slicing mechanism 23. The slicing mechanism 23 is configured to slice the battery piece to divide the battery piece into at least two battery piece slices. The transfer mechanism 22 is further configured to transfer the at least two battery piece slices to the output mechanism 24. The output mechanism 24 is configured to transport the at least two battery piece slices to the drying device 3.

[0090] The drying device 3 is configured to dry the at least two battery piece slices.

[0091] The working process of the battery piece slicing device in the embodiment of the present application is as follows:

[0092] The feeding device 1 first feeds the battery piece to be sliced to the input mechanism 21 of the slicing device 2.

[0093] The input mechanism 21 transports the battery piece to be sliced towards the transfer mechanism 22.

[0094] The transfer mechanism 22 moves to the discharge end of the input mechanism 21 and obtains the battery piece to be sliced from the discharge end of the input mechanism 21.

[0095] The transfer mechanism 22 transfers the battery piece to be sliced to below the slicing mechanism 23.

[0096] The slicing mechanism 23 performs slicing operation on the battery piece to divide the battery piece into at least two battery piece slices.

[0097] Then, the transfer mechanism 22 transfers the at least two battery piece slices obtained by slicing to the input end of the output mechanism 24.

[0098] The output mechanism 24 transports the battery piece slices to the drying device 3.

[0099] The drying device 3 dries the battery piece slices.

[0100] The battery piece slicing device provided by the embodiment of the application is used to slice the battery piece, after the loading device 1 loads the battery piece to be sliced onto the input mechanism 21 of the slicing device 2, the transfer mechanism 22 obtains the battery piece from the input mechanism 21, and then moves the battery piece to the lower side of the slicing mechanism 23. After the slicing is completed, the transfer mechanism 22 moves the sliced battery piece to the output mechanism 24 of the slicing device 2, and the output mechanism 24 directly transports the sliced battery piece to the drying device 3 for drying.

[0101] Compared with the existing battery piece slicing device, the battery piece slicing device provided by the embodiment of the application greatly reduces the pickup and transport times of the battery piece, thereby reducing the damage risk of the battery piece.

[0102] As shown in Figures 2 to 4 Optionally, the loading device 1 comprises a loading conveying mechanism 11, a battery box backflow conveying mechanism 12 and a transfer mechanism 13, wherein:

[0105] The loading conveying mechanism 11 is used to convey the battery box containing the battery piece to the loading station, and convey the emptied battery box from the loading station to the transfer part 132 located at the discharge end of the loading conveying mechanism 11.

[0106] The battery box backflow conveying mechanism 12 is used to receive the emptied battery box from the transfer part 132 located at the feeding end of the battery box backflow conveying mechanism 12, and convey the emptied battery box to the backflow station.

[0107] The specific loading process of the loading device 1 is as follows:

[0108] The loading conveying mechanism 11 conveys the battery box 15 containing the battery piece to the loading station, the battery piece in the battery box at the loading station is taken out through the loading mechanism or manually, and the taken-out battery piece is loaded to the input mechanism 21 of the slicing device 2.

[0109] The translation part 131 drives the transfer part 132 to the discharge end of the loading conveying mechanism 11, and the loading conveying mechanism 11 conveys the emptied battery box 15 from the loading station to the transfer part 132.

[0110] The translation part 131 drives the transfer part 132 carrying the emptied battery box 15 to the inlet end of the battery box backflow conveying mechanism 12.

[0111] The transfer part 132 cooperates with the battery box backflow conveying mechanism 12 to convey the emptied battery box 15 to the inlet end of the battery box backflow conveying mechanism 12.

The lifting mechanism 161 is used to drive the suction cup assembly 163 to lift, and the rotating mechanism 162 is used to drive the suction cup assembly 163 to rotate. Through the cooperation of the lifting mechanism 161 and the rotating mechanism 162, the suction cup assembly 163 can pick up the battery piece from the battery box, and feed the picked battery piece to the next station.

[0127] As shown in Figure 10 Optionally, the transfer mechanism 22 of the scribing device 2 comprises a first translation module 221, a lifting module 222 and a transfer platform 223, wherein the lifting module 222 is connected to the driving end of the first translation module 221, and the transfer platform 223 is connected to the driving end of the lifting module 222, and the transfer platform 223 is provided with a suction assembly 224 protruding upward from the transfer platform 223. The first translation module 221 is used to drive the transfer platform 223 to reciprocate between the input mechanism 21 and the output mechanism 24, and the lifting module 222 is used to drive the transfer platform 223 to lift.

[0128] The working process of the transfer mechanism 22 in some optional embodiments is as follows:

[0129] Firstly, the lifting module 222 moves the transfer platform 223 to the low position.

[0130] When the input mechanism 21 delivers the battery piece to be scribed to the discharge end, the first translation module 221 drives the transfer platform 223 to translate towards the input mechanism 21 until the transfer platform 223 reaches below the battery piece to be scribed.

[0131] Then, the lifting module 222 drives the transfer platform 223 to rise to the high position, in the process, the suction assembly 224 adsorbs the battery piece to be scribed, and finally lifts the battery piece to be scribed upward out of the discharge end of the input mechanism 21.

[0132] Then, the first translation module 221 moves the transfer platform 223 with the battery piece to be scribed adsorbed to below the scribing mechanism 23.

[0133] After the dicing mechanism 23 completes the dicing of the battery cells, the first translation module 221 drives the transfer platform 223 to move toward the output mechanism 24 until the diced battery cells reach above the feed end of the output mechanism 24.

[0134] Next, the lifting module 222 drives the transfer platform 223 to a low position. This causes the battery cells adsorbed on the transfer platform 223 to fall onto the feed end of the output mechanism 24.

[0135] like Figure 11 As shown, in some embodiments, the battery cell is divided into two battery cell slices. The adsorption assembly 224 includes two adsorption plates 2241 arranged side by side, and a sizing clearance gap 2242 is formed between the two adsorption plates 2241 corresponding to the sizing position of the battery cell. The extending direction of the sizing clearance gap 2242 is parallel to the movement direction of the transfer platform 223 (e.g., ...). Figure 11 (The direction of the arrow in the image).

[0136] When the first translation module 221 moves the battery cell adsorbed on the adsorption assembly 224 to below the dicing mechanism 23, the dicing mechanism 23 dices the battery cell along the dicing clearance gap 2242, thereby dividing the battery cell into two battery cell slices. The two battery cell slices are then adsorbed onto an adsorption plate 2241.

[0137] like Figures 12 to 13 As shown, optionally, the dicing mechanism 23 includes a second translation module 231, a first mounting bracket 232, a grooving laser 233, a heating laser 234, and a cooling assembly 235.

[0138] The first mounting bracket 232 is connected to the drive end of the second translation module 231. The grooving laser 233, the heating laser 234, and the cooling component 235 are all adjustablely mounted on the first mounting bracket 232. The second translation module 231 drives the first mounting bracket 232 to translate perpendicularly to the movement direction of the transfer mechanism 22, so as to move the grooving laser 233, the heating laser 234, and the cooling component 235 to the dicing station above the battery cell to be diced. The grooving laser 233 forms dicing grooves on the surface of the battery cell, the heating laser 234 heats the battery cell along the extension direction of the dicing grooves, and the cooling component 235 cools the heated battery cell, causing it to shrink and split along the dicing grooves to obtain two separate battery cells.

[0139] As is known to those skilled in the art, in order to facilitate the subsequent processing steps of dicing the battery cells, after the dicing of the battery cells is completed, it is necessary to separate the two battery cell segments obtained by dicing so that the spacing between the two battery cell segments meets the predetermined requirements.

[0140] In order to implement automatic spacing of the two battery piece fragments, as shown in Figures 14 to 16 Optionally, the output mechanism 24 comprises a first conveying part 241 and a second conveying part 242 arranged side by side at intervals, wherein the transfer mechanism 22 transfers the battery piece fragments 101 and 102 obtained by the scribing to the first conveying part 241 and the second conveying part 242 respectively. The first conveying part 241 and the second conveying part 242 output the battery piece fragments 101 and 102 synchronously.

[0141] In particular, as shown in Figure 15 The distance a between the inlet end of the first conveying part 141 and the inlet end of the second conveying part 142 is less than the distance b between the outlet end of the first conveying part 141 and the outlet end of the second conveying part 142. That is, along the output direction of the output mechanism 14 (such as the arrow direction in Figure 15 , the distance between the first conveying part 141 and the second conveying part 142 gradually increases. In this way, the distance between the battery piece fragments 101 and 102 gradually increases, thereby achieving automatic spacing of the battery piece fragments 101 and 102.

[0142] In order to improve the scribing efficiency of the scribing device 2, as shown in Figure 11 Optionally, the transfer mechanism 22 comprises two transfer platforms 223, which alternately obtain the battery piece from the input mechanism 21 and transfer the battery piece to the lower side of the scribing mechanism 23 under the driving of the corresponding first translation module 221 and the lifting module 222, and transfer the battery piece fragments to the output mechanism 24.

[0143] As shown in Figure 11 and Figure 14 Optionally, the input mechanism 21 is arranged side by side into two groups, the output mechanism 24 is arranged side by side into two groups, and the transfer platform 223 is arranged side by side with two suction assemblies 224, wherein each suction assembly 224 corresponds to a group of input mechanisms 21 and a group of output mechanisms 24. Two groups of input mechanisms 21 synchronously input two battery pieces to be scribed. Two suction assemblies 224 respectively lift and adsorb one battery piece from the corresponding input mechanism 21. After scribing, each suction assembly 224 respectively transfers two battery piece fragments obtained by scribing to the corresponding output mechanism 24.

[0144] In this way, synchronous scribing of two battery pieces input side by side can be achieved, thereby further improving the scribing efficiency of the scribing device 2.

[0145] As shown in Figures 17 to 19 Optionally, the drying device 3 comprises a conveying mechanism 31 and a drying mechanism 32, wherein:

[0146] The conveying mechanism 31 comprises a first conveying belt 311 and a second conveying belt 312 arranged side by side and spaced apart, and the first conveying belt 311 and the second conveying belt 312 are configured to convey the first battery sub-piece 101 and the second battery sub-piece 102 formed by the same battery piece slicing synchronously, wherein:

[0147] The first battery sub-piece 101 is located on the first conveying belt 311, and the second battery sub-piece 102 is located on the second conveying belt 312, and the side edges (i.e. Figure 19 The side edge 101a of the first battery sub-piece 101 and the side edge 102a of the second battery sub-piece 102 in the dashed box in FIG. 1) of the first battery sub-piece 101 and the second battery sub-piece 102 close to each other are the slicing side edges formed by slicing.

[0148] 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 slicing side edges of the first battery sub-piece 101 and the second battery sub-piece 102.

[0149] 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 sub-pieces, and in particular, the drying mechanism 32 only implements the local drying of the slicing side edges close to each other of the two battery piece sub-pieces, thereby reducing the drying energy consumption.

[0150] As shown in FIGS. Figure 17 and Figure 18 Optionally, the drying mechanism 32 comprises 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 conveying belt 311 and the second conveying belt 312 and between the first conveying belt 311 and the second conveying belt 312, and the drying assembly 322 is used for heating the slicing side edges of the first battery sub-piece 101 and the second battery sub-piece 102.

[0151] 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 provide drying heat energy to the slicing side edges of the first battery sub-piece 101 and the second battery sub-piece 102 passing through in sequence.

[0152] By mounting 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 processes are realized for the slicing side edges of the first battery sub-piece 101 and the second battery sub-piece 102, thereby further ensuring the drying effect.

[0153] As shown in FIGS. Figures 20 to 23As shown, the drying assembly 322 comprises a heating chamber 323, an air inlet part 324 and a heating part 325. The heating chamber 323 is internally provided with an air flow channel 326, and the bottom of the heating chamber 323 is provided with a plurality of air outlet holes 327 communicating with the air flow channel 326. The air inlet part 324 communicates with the air flow channel 326, and is used to pass external air into the air flow channel 326 and drive the air to flow in the air flow channel 326. The heating part 325 is arranged in the heating chamber 323, and is used to heat the air in the air flow channel 326. The heated air is finally blown downward through the air outlet holes 327 to dry the scribing side of the first battery piece 101 and the second battery piece 102.

[0154] As shown in Figure 22 and Figure 23 As shown, the two opposite inner walls of the heating chamber 323 are provided with a plurality of baffles 328 arranged in the vertical direction. The plurality of baffles 328 form a meandering air flow channel 326 in the heating chamber 323.

[0155] By forming the meandering air flow channel 326 in the heating chamber 323, the heating distance of the heating part 325 to the air entering the heating chamber 323 can be effectively prolonged, so that the drying temperature of the hot air blown to the scribing side of the first battery piece 101 and the second battery piece 102 can meet the drying requirements.

[0156] As shown in Figure 24 As shown, the heating chamber 323 is symmetrically provided with two air flow channels 326, and the heating part 325 is arranged between the two air flow channels 326. One air flow channel 326 is close to the first conveying belt 311, and the hot air blown from the air flow channel 326 is used to dry the scribing side of the battery piece 101. The other air flow channel 326 is close to the second conveying belt 312, and the hot air blown from the air flow channel 326 is used to dry the scribing side of the battery piece 102.

[0157] By arranging two symmetric 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 volume and temperature of the hot air blown to the scribing side of the first battery piece 101 and the scribing side 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 of the first battery piece 101 and the scribing side of the second battery piece 102 is ensured.

[0158] As shown in Figure 1As shown, optionally, the battery cell slicing equipment in this embodiment of the invention further includes a feeding device 4 disposed after the drying device 3. The feeding end of the feeding device 4 is connected to the discharging end of the drying device 3, and the feeding device 4 is used to collect the dried battery cell slices output by the drying device 3.

[0159] By setting up a feeding device 4 and connecting the feeding end of the feeding device 4 with the discharging end of the drying device 3, the feeding device 4 can automatically collect the dried battery cells output by the drying device 3.

[0160] like Figure 25 and Figure 26 As shown, the feeding device 4 includes a feeding mechanism 41 and a lifting mechanism 42, wherein:

[0161] The unloading mechanism 41 includes a third mounting bracket 411 and at least two sliding support plates 412 arranged layer by layer on the third mounting bracket 411 in a vertical direction. Each sliding support plate 412 carries an unloading component 413. Each sliding support plate 413 is configured to slide horizontally on the third mounting bracket 411 independently, so as to drive the corresponding unloading component 413 to switch between its respective receiving position and unloading position.

[0162] The lifting mechanism 42 is used to lift the unloading assembly 413 located at the receiving position away from the sliding support plate 412 so that the unloading assembly 413 can be connected to the discharge end of the drying device 3.

[0163] The lifting mechanism 42 is also used to place the unloading assembly 413 back onto the sliding support plate 412 after the unloading assembly 413 has finished receiving the material.

[0164] by Figure 25 Taking the feeding device 4 with three sliding support plates 412 as an example in the embodiment, its optional material receiving process is as follows:

[0165] When the material receiving is not started, all three sliding support plates 412 are far away from the lifting mechanism 42, and the unloading components 413 on each sliding support plate 412 are in their respective discharge positions, and each unloading component 413 is empty.

[0166] Start receiving materials:

[0167] First, control one of the sliding support plates 412 to move toward the lifting mechanism 42 until the unloading component 413 on the sliding support plate 412 switches to its receiving position.

[0168] The lifting mechanism 42 lifts the unloading component 413, which is located at the receiving position, away from the sliding support plate 412, so that it connects with the discharge end of the drying device 3.

[0169] When the unloading assembly 413 located at the receiving station is full of the battery pieces output by the drying device 3, the jacking mechanism 42 is lowered to the home position, so that the unloading assembly 413 full of the battery pieces returns to the corresponding sliding support plate 412.

[0170] Then, the sliding support plate 412 carrying the unloading assembly 413 full of the battery pieces moves away from the jacking mechanism 42 until the unloading assembly 413 full of the battery pieces switches to the discharging position. The battery pieces in the unloading assembly 413 full of the battery pieces are taken out, and at the same time, the other sliding support plate 412 is controlled to move towards the jacking mechanism 42 until the unloading assembly 413 on the other sliding support plate 412 switches to the receiving position.

[0171] As can be seen, the unloading assembly 413 on each sliding support plate 412 can be alternately moved to the corresponding receiving position, so that the jacking mechanism 42 can timely lift the unloading assembly 413 to be received to the receiving station, preventing the receiving station from waiting for receiving due to the shortage of the unloading assembly 413. In addition, the battery pieces in the unloading assembly 413 full of the battery pieces are taken out when the unloading assembly 413 full of the battery pieces moves to the corresponding discharging position. Therefore, the battery piece taking-out operation and the receiving operation at the receiving station can be implemented synchronously and do not interfere with each other.

[0172] As shown in Figure 26 Optionally, the unloading assembly 413 includes a bottom plate 414 and a rack 415, wherein the bottom plate 414 is carried on the sliding support plate 412, and the rack 415 is arranged on the bottom plate 414.

[0173] When the unloading assembly 413 switches to the receiving position, the jacking mechanism 42 lifts the bottom plate 414 of the unloading assembly 413 upwards to lift the unloading assembly 413 away from the sliding support plate 412.

[0174] After the rack 415 of the unloading assembly 413 completes the receiving, the jacking mechanism 42 is lowered to the home position to place the bottom plate 414 of the unloading assembly 413 back on the sliding support plate 412.

[0175] In order to implement the synchronous receiving and unloading of the two battery pieces output by the drying device 3 side by side, as shown in Figure 26 Optionally, the racks 415 are arranged in pairs, and each pair of racks 415 is used to synchronously receive the two battery pieces conveyed side by side by the drying device 3. Figure 26 The unloading assembly 413 in the embodiment is provided with two pairs of racks 415.

[0176] Optionally, as shown in Figure 26As shown, 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 pieces can be kept in the rack 415, preventing the battery pieces from sliding out of the rack 415.

[0177] As shown in Figure 25 Optionally, the jacking mechanism 42 comprises a jacking driving part 421 and a jacking plate 422, wherein the jacking plate 422 is connected to the driving end of the jacking driving part 421, and the jacking driving part 421 is used to drive the jacking plate 422 to ascend and descend.

[0178] When the discharging assembly 413 is switched to the collecting position, the jacking driving part 421 drives the jacking plate 422 to ascend, so that the jacking plate 422 jacks the discharging assembly 413 away from the sliding support plate 412 until the discharging assembly 413 reaches the collecting station.

[0179] After the discharging assembly 413 is full of battery pieces, the jacking driving part 421 drives the jacking plate 422 to descend to the original position, so that the jacking plate 422 puts the discharging assembly 413 full of battery pieces back onto the corresponding sliding support plate 412.

[0180] The above description of the present application is sufficiently detailed and has certain particularity. It should be understood by those skilled in the art that the description in the embodiments is only exemplary, and all changes made without departing from the true spirit and scope of the present application should belong to the protection scope of the present application. The scope of protection claimed by the present application is defined by the claims, not by the above description of the embodiments.
