[0072] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0073] As shown in Figures 1 to 10 The battery piece processing equipment in the embodiment of the present application includes a feeding conveying part 1, a transition conveying part 2, a wafer taking conveying part 3, a wafer taking part 4, and a processing part 5, wherein:

[0074] The feeding conveying part 1 includes feeding conveying mechanisms 11 and backflow conveying mechanisms 12 arranged in an up-down manner, and the feeding conveying mechanisms 11 and the backflow conveying mechanisms 12 are both configured to convey the material boxes along a first horizontal direction (such as the X-axis direction in the figure), and the conveying directions of the two are opposite.

[0075] The wafer taking conveying part 3 is arranged at the rear of the feeding conveying part 1, and the wafer taking conveying part 3 includes at least two wafer taking conveying mechanisms 31, and the wafer taking conveying mechanisms 31 are configured to convey the material boxes along the first horizontal direction, and each wafer taking conveying mechanism 31 is correspondingly provided with a wafer taking station on the conveying path thereof.

[0076] The transition conveying part 2 is arranged between the feeding conveying part 1 and the wafer taking conveying part 3.

[0077] The feeding conveying mechanism 1 is configured to convey the box loaded with battery pieces to the transition conveying part 2, the transition conveying part 2 is configured to transitionally convey the box loaded with battery pieces to the piece taking conveying mechanism 31, and the piece taking conveying mechanism 31 is configured to convey the box loaded with battery pieces to the corresponding piece taking station.

[0078] The piece taking part 4 is configured to pick up the battery pieces from the box at the piece taking station of any piece taking conveying mechanism 31 and feed the battery pieces into the processing part 5, and the processing part 5 is configured to process the battery pieces.

[0079] The piece taking conveying mechanism 31 is further configured to convey the empty box at the piece taking station back to the transition conveying part 2, and the transition conveying part 2 is further configured to transitionally convey the empty box to the backflow conveying mechanism 12, and the backflow conveying mechanism 12 is configured to convey the empty box to the backflow station.

[0080] The battery piece processing equipment in the embodiment of the present application has the feeding conveying mechanism 11 and the backflow conveying mechanism 12 arranged above and below, and the transition conveying part 2 can be alternately connected with the feeding conveying mechanism 11 and the backflow conveying mechanism 12 through lifting movement, so as to implement the transition conveying of the full box and the empty box. In this way, the battery piece processing equipment of the present application has a more compact structure and occupies a smaller area.

[0081] In addition, since the piece taking conveying part 3 includes at least two piece taking conveying mechanisms 31, when the box at the piece taking station of one piece taking conveying mechanism 31 is emptied and the box is replaced, the piece taking part 4 can pick up the battery pieces from the box at the piece taking station of another piece taking conveying mechanism 31 to implement continuous feeding of the processing part 5, so as to avoid the processing part 5 from waiting for lack of materials and ensure the processing rhythm of the processing part 5.

[0082] As shown in Figure 5 The transition conveying part 2 includes a driving module 21 and a transition conveying mechanism 22 connected to the driving module 21, the driving module 21 is used to drive the transition conveying mechanism 22 to translate and lift along a second horizontal direction (such as the Y-axis direction in the figure) to drive the transition conveying mechanism 22 to be connected with the feeding conveying mechanism 11, the backflow conveying mechanism 12 or the piece taking conveying mechanism 31, wherein the second horizontal direction is perpendicular to the first horizontal direction.

[0083] The transition conveying mechanism 22 can implement bidirectional conveying in the first horizontal direction. When the transition conveying mechanism 22 is connected with the feeding conveying mechanism 11, the transition conveying mechanism 22 receives the box containing the battery pieces conveyed by the feeding conveying mechanism 11. When the transition conveying mechanism 22 is connected with the piece taking conveying mechanism 31, the transition conveying mechanism 22 conveys the box containing the battery pieces to the piece taking conveying mechanism 31, or receives the empty box conveyed back by the piece taking conveying mechanism 31. When the transition conveying mechanism 22 is connected with the returning conveying mechanism 12, the transition conveying mechanism 22 conveys the empty box to the returning conveying mechanism 12.

[0084] It can be seen that, by implementing the above-mentioned arrangement on the transition conveying part 2, the transition conveying part 2 can not only convey the box containing the battery pieces conveyed by the feeding conveying mechanism 11 to the piece taking conveying mechanism 31, but also convey the empty box conveyed back by the piece taking conveying mechanism 31 to the returning conveying mechanism 12.

[0085] Optionally, the driving module 21 comprises a first translation module 211 and a first lifting module 212, wherein the first lifting module 212 is connected to the movable part of the first translation module 211, and the transition conveying mechanism 22 is connected to the movable part of the first lifting module 212, the first translation module 211 is configured to drive the transition conveying mechanism 22 to translate along the second horizontal direction, and the first lifting module 212 is configured to drive the transition conveying mechanism 22 to lift.

[0086] By arranging the driving module 21 to comprise the first translation module 211 and the first lifting module 212, the driving module 21 can adjust the horizontal position and the height of the transition conveying mechanism 22, so that the transition conveying mechanism 22 can be connected with the feeding conveying mechanism 11, the returning conveying mechanism 12 or the piece taking conveying mechanism 31.

[0087] Optionally, as shown in Figure 7 The piece taking conveying mechanism 31 further comprises a jacking assembly 32 arranged below the piece taking station, the jacking assembly 32 is configured to jack up the battery pieces in the box located at the piece taking station, so that the topmost battery piece in the box is jacked up to a predetermined piece taking height. In this way, the piece taking part 4 can take the battery pieces from the same height each time, which facilitates the piece taking operation of the piece taking part 4.

[0088] Optionally, the side of the piece taking conveying mechanism 31 is provided with a lifting in-place sensor 33 and an air knife assembly 34, wherein the lifting in-place sensor 33 is used to detect whether the topmost battery piece in the magazine is lifted in place. When the lifting in-place sensor 33 senses that the topmost battery piece is lifted in place, it sends an in-place signal to the control end of the lifting assembly 32, and the lifting assembly 32 stops lifting immediately. In this way, it can be ensured that the topmost battery piece in the magazine is accurately lifted to the predetermined piece taking height.

[0089] As shown in Figures 3 to 4 , optionally, the upper conveying part 1 and the transition conveying part 2 are both provided as two groups in parallel, and the piece taking conveying part 3 is also provided as two groups in parallel.

[0090] In this way, one upper conveying part 1 and one transition conveying part 2 on one side (such as side A in Figure 4 ) and another upper conveying part 1 and another transition conveying part 2 on the other side (such as side B in Figure 4 ) can supply the magazine containing battery pieces to the rear piece taking conveying part 3 in parallel, and take the empty magazine from the rear piece taking conveying part 3, so as to further improve the conveying efficiency of the magazine. In addition, when one of the upper conveying part 1 or the transition conveying part 2 on one side fails, the upper conveying part 1 and the transition conveying part 2 on the other side can continue to convey the magazine, ensuring that there is a magazine containing battery pieces on at least one side of the piece taking conveying part 3, and preventing the upper conveying from being interrupted.

[0091] Optionally, the battery piece processing equipment in the embodiment of the application further comprises an AGV car arranged in front of the upper conveying part 1, which is used to load the magazine containing battery pieces to the inlet end of the upper conveying mechanism 11, and to recover the empty magazine from the outlet end of the return conveying mechanism 12.

[0092] By arranging the AGV car, the automatic circulation of the magazine between the upper conveying part 1 and the battery piece supply station is realized, that is, the magazine containing battery pieces at the battery piece supply station is loaded to the inlet end of the upper conveying mechanism 11, and the empty magazine output from the outlet end of the return conveying mechanism 12 is sent back to the battery piece supply station for loading, thereby forming a closed circulation of the magazine circulation.

[0093] As shown in Figure 11As shown, the taking section 4 comprises a second translation module 41, a second lifting module 42, a first rotation module 43 and a first suction assembly 44, wherein: the second lifting module 42 is connected to the movable part of the second translation module 41, the first rotation module 43 is connected to the movable part of the second lifting module 42, and the first suction assembly 44 is connected to the movable part of the first rotation module 43. The second translation module 41 is configured to drive the first suction assembly 44 to translate in the second horizontal direction, the second lifting module 42 is configured to drive the first suction assembly 44 to lift, and the first rotation module 43 is configured to drive the first suction assembly 44 to rotate in the horizontal plane. Through the cooperation of the second translation module 41, the second lifting module 42 and the first rotation module 43, the first suction assembly 44 can pick up the battery sheet from the magazine located at any taking station of the taking conveying mechanism 31, and feed the battery sheet to the same position on the processing section 4.

[0094] Optionally, the processing section 5 is a slicing processing section. As shown, Figure 6 the slicing processing section comprises a slicing conveying section 51 and a laser slicing section 52, wherein: the slicing conveying section 51 is configured to receive the battery sheet fed by the taking section 4, and convey the battery sheet to a slicing station along a first horizontal direction. The laser slicing section 52 is located above the slicing station, and is configured to slice the battery sheet to divide the battery sheet into at least two battery sheet pieces. The slicing conveying section 51 is further configured to convey the at least two battery sheet pieces to a discharging station located behind the slicing station along the first horizontal direction.

[0095] Optionally, the slicing conveying section 51 comprises a third translation module 511, a second rotation module 512 and a carrier plate 513, wherein: the second rotation module 512 is connected to the movable part of the third translation module 511, and the carrier plate 513 is connected to the movable part of the second rotation module 512.

[0096] The carrier plate 513 is driven by the third translation module 511 to convey the battery sheet to be sliced to the slicing station, and to convey the sliced battery sheet pieces to the discharging station, thereby realizing automatic feeding of the sliced battery sheet and automatic discharging of the sliced battery sheet pieces.

[0097] The second rotation module 512 can adjust the angle of the battery sheet to be sliced before and during slicing, ensuring that the laser slicing section 52 accurately slices the battery sheet along the target area of the battery sheet.

[0098] Optionally, as shown, Figures 12 to 13As shown, the laser scribing part 52 comprises a fourth translation module 521, a mounting bracket 522, a slotting laser 523 and a splitting laser 524. The mounting bracket 522 is connected to the driving end of the fourth translation module 521, and the fourth translation module 521 is configured to drive the mounting bracket 522 to translate along a second horizontal direction. The slotting laser 523 and the splitting laser 524 are mounted on the mounting bracket 522. The slotting laser 523 is configured to form a slot on the end of the battery piece, and the splitting laser 524 is configured to heat the battery piece along the extension direction of the slot, so that the battery piece is split along the extension direction of the slot to obtain two battery pieces.

[0099] As described above, in order to ensure that the laser scribing part 52 precisely scribes the battery piece along the target area of the battery piece, the second rotation module 512 can be configured to drive the carrier plate 513 to rotate in the horizontal plane to adjust the angle of the battery piece.

[0100] Optionally, the slotting laser 523 and the splitting laser 524 in the laser scribing part 52 can also be controlled to perform interpolation motion to ensure that the slotting laser 523 and the splitting laser 524 precisely scribe the battery piece along the target area of the battery piece.

[0101] Specifically, since the mounting bracket 522 is connected to the driving end of the fourth translation module 521, during the scribing process, the third translation module 511 drives the battery piece to translate along the first horizontal direction through the carrier plate 513, and synchronously, the fourth translation module 521 can drive the slotting laser 523 and the splitting laser 524 to translate along the second horizontal direction perpendicular to the first horizontal direction through the mounting bracket 522, so that the slotting laser 523 and the splitting laser 524 can precisely scribe the battery piece along the target area of the battery piece.

[0102] Optionally, the battery piece processing device in the embodiment of the present application further comprises a positioning part arranged above the scribing conveying part 51. The positioning part is configured to position the battery piece before scribing. The scribing conveying part 51 conveys the battery piece to the scribing station based on the position information of the battery piece, and the laser scribing part 52 scribes the battery piece based on the position information of the battery piece.

[0103] For example, the positioning unit, the third translation module 511 of the slice conveying unit 51, and the fourth translation module 521 of the laser slicing unit 52 are all connected with the controller. The positioning unit sends the position information of the battery piece to be sliced to the controller. According to the position information of the battery piece to be sliced, the controller sends control instructions to the third translation module 511 and the fourth translation module 521, so that the third translation module 511 and the fourth translation module 521 cooperate with each other to drive the battery piece, the slotting laser 523 and the splitting laser 524 to implement the interpolation motion described above during the slicing process, thereby ensuring that the slotting laser 523 and the splitting laser 524 implement accurate slicing on the battery piece along the target area of the battery piece.

[0104] Optionally, as shown in Figures 1 to 2 , the battery piece processing equipment in the embodiment of the application further comprises a feeding unit 6, which is arranged at the rear of the laser slicing unit 52. The feeding unit 6 is used to pick up the battery piece fragments from the feeding station and transitionally convey the picked-up battery piece fragments to the rear station.

[0105] As shown in Figures 14 to 15 , optionally, the feeding unit 6 comprises a fifth translation module 61, a third rotation module 62, a third lifting module 63 and a second suction assembly 64, wherein the third rotation module 62 is connected to the moving part of the fifth translation module 61, the third lifting module 63 is connected to the moving part of the third rotation module 62, and the second suction assembly 64 is connected to the moving part of the third lifting module 64.

[0106] The fifth translation module 61 is used to drive the second suction assembly 64 to translate, the third rotation module 62 is used to drive the second suction assembly 64 to rotate in the horizontal plane, and the third lifting module 63 is used to drive the second suction assembly 64 to lift, so as to drive the second suction assembly 64 to pick up the battery piece fragments from the feeding station C and rotationally convey the picked-up battery piece fragments to the rear station D, so that the angle of the battery piece fragments fed to the rear station D meets the processing requirements of the rear station.
