[0079] The specific embodiments of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the embodiments of the present application, and are not used to limit the embodiments of the present application.

[0080] Figure 1 is a structural schematic diagram of a grouping test device of a new energy battery cell module according to an embodiment of the present application; Figure 2 is a position schematic diagram of a slitting assembly and a moving mechanism in the grouping test device of the new energy battery cell module according to an embodiment of the present application. In Figure 1 and Figure 2 , the grouping test device can include a slitting assembly, a moving mechanism, a limiting assembly and a test assembly. Specifically, the slitting assembly can include a slitting cutter 20 and a driving assembly.

[0081] The driving assembly is connected with the slitting cutter 20 and is used to drive the slitting cutter 20 to move. The moving mechanism is arranged on one side close to the tip of the slitting cutter 20 and is used to drive the cell module 12 to move in a direction perpendicular to the moving direction of the slitting cutter 20 and cooperate with the slitting cutter 20 to slit the cell module 12. The limiting assembly is arranged on the moving mechanism and is used to clamp and fix the cells other than the first cell close to the slitting cutter 20 of the cell module 12. The test assembly is arranged on the side of the moving mechanism away from the slitting cutter 20 and is used to test the slitted cell.

[0082] When it is needed to recycle the single cell of the cell module 12, the cell module 12 is placed above the moving mechanism, and the cell module 12 is driven by the moving mechanism to move in a direction perpendicular to the moving direction of the slitting cutter 20, that is, the cell module 12 is gradually driven to move close to the slitting cutter 20. When the cell module 12 reaches the slitting position, the limiting assembly fixes the cells other than the first cell close to the slitting cutter 20 of the cell module 12, that is, fixes the cells other than the cell to be cut. Then the slitting cutter 20 is driven by the driving assembly to move and cut into the joint gap between the first cell and the adjacent cell, so that the first cell is separated from the remaining cells. Finally, the performance of the slitted cell is tested by the test assembly, so as to determine whether the cell can be recycled.

[0083] When the cell module of the conventional new energy battery is cut, the corresponding operator generally uses a cutter to slit the cells of the cell module one by one, and then recycles after detection by the detection personnel. However, the manual slitting and detection of the cell require high experience of the operator, and the cell itself is easy to be damaged, so the loss caused by the cell defect due to the cutting is large. In addition, due to the structural characteristics of the cell itself, there is a certain safety hazard. In the embodiment of the present application, the limiting assembly and the slitting cutter 20 cooperate to slit the cell module 12 one by one, which can effectively reduce the cell defect rate caused by manual cutting on the one hand, and avoid the occurrence of safety accidents on the other hand through automatic cutting operation of the equipment.

[0084] In the embodiment of the present application, as shown inFigure 1 and Figure 2 As shown in FIG. 1, the moving mechanism can include a slitting base 22 and a moving box 10. Specifically, the moving box 10 can include a moving opening 18, a push plate 15, and a first ball screw 11. Specifically, the first ball screw 11 can include a first ball screw body and a first servo motor.

[0085] The moving box 20 is arranged on the top of the slitting base 22, the moving opening 18 is arranged on the top of the moving box 10, the push plate 15 penetrates through the moving opening 18, the upper end of the push plate 15 is used to abut against the other end of the battery cell module 12, the first ball screw 11 is arranged in the interior of the moving box 10, and the nut of the first ball screw 11 is connected with the lower end of the push plate 15. The first servo motor is connected with one end of the first ball screw body.

[0086] When it is needed to slit the battery cell module 12, the battery cell module 12 is placed above the moving opening 18, and then the push plate 15 is driven to move by the first ball screw 11, the push plate 15 gradually abuts against the other end of the battery cell module 12 and gradually pushes the battery cell module 12 to move along the slitting cutter 20. When the battery cell module 12 moves to the slitting position, the first battery cell is slit by the slitting cutter 20, and after the slitting is completed, the battery cell module 12 is pushed to move a preset distance by the push plate 15 through the first ball screw 11, so as to realize the slitting of the battery cell module 12. The mode that the push plate 15 pushes the battery cell module 12 by the first ball screw 11 can facilitate the slitting of the plurality of battery cells on the battery cell module 12 in sequence, and the driving is stable and reliable, and the precision during the slitting of the slitting cutter 20 can be improved.

[0087] In the embodiment of the present application, as shown in Figure 1 and Figure 2 The moving box 10 can further include a first non-metallic backing plate 17.

[0088] The first non-metallic backing plate 17 is arranged on the top of the moving box 10, and the first non-metallic backing plate 17 is arranged on the side of the moving opening 18.

[0089] When the battery cell module 12 moves along the slitting cutter 20, the first non-metallic backing plate 17 can protect the bottom of the battery cell module 12, so as to avoid the plurality of battery cells in the battery cell module 12 from being damaged during the movement, and thus the cost of slitting recovery is increased.

[0090] In the embodiment of the present application, the number of the first non-metallic backing plate 17 can be various forms known by those skilled in the art, such as one, two, etc. However, in one preferred example of the present application, considering the stability and integrity of the movement of the battery cell module 12, the specific number of the first non-metallic backing plate 17 can be as shown in Figure 1 and Figure 2 Specifically, inFigure 1 and Figure 2 In the first non-metallic pad plate 17, the number of two. Specifically, two first non-metallic pad plate 17 along the two sides of the moving opening distribution.

[0091] In this embodiment of the application, as Figure 1 and Figure 2 The limiting assembly can include a first limiting plate 16, a second limiting plate 19 and a first cylinder 13.

[0092] The first limiting plate 16 is arranged on the top of the moving box 10 and located on one side of the moving opening 18, the second limiting plate 19 is arranged on the other side of the moving opening 18, and the first cylinder 13 is arranged on the top of the slitting base 22, and the output end of the first cylinder 13 is connected with the side of the second limiting plate 19 away from the first limiting plate 16.

[0093] When the battery cell module 12 moves to the slitting position, the first cylinder 13 is started and drives the second limiting plate 19 to move, so that the second limiting plate 19 gradually fits with the side wall of the battery cell module 12 and cooperates with the first limiting plate 16 to fix the battery cells other than the battery cell to be slitted. By using the cooperation of the first limiting plate 16 and the second limiting plate 19, the position of the battery cell module 12 on the moving box 10 can be accurately limited to ensure the accurate cutting of the slitting cutter 20, which helps to improve the slitting yield of the slitting cutter 20.

[0094] In this embodiment of the application, in order to protect the first limiting plate 16 and the second limiting plate 19 from damaging the side wall of the battery cell module 12 during the limiting and fixing process, the opposite inner side walls of the first limiting plate 16 and the second limiting plate 19 are provided with second non-metallic pad plates.

[0095] In this embodiment of the application, as Figure 1 and Figure 2 The driving assembly can include a driving seat 2 and a first cylinder 1.

[0096] When the battery cell module 12 is fixed, the first cylinder 1 drives the slitting cutter 20 to enter the gap between the battery cell to be slitted and the adjacent battery cell, and gradually separates the battery cell to be slitted and the battery cell module 12. Similarly, the plurality of battery cells on the battery cell module 12 can be sequentially slitted. By using the first cylinder 1 to drive the slitting cutter 20, the battery cell slitting is more stable and gentle, the battery cells are protected, and the slitting is simple, which is conducive to improving the slitting efficiency of the battery cell module 12. In addition, the pushing force of the first cylinder 1 is large, so that the slitting cutter 20 can better slitting the battery cell and the battery cell module 12.

[0097] In this embodiment of the application, as Figure 1 and Figure 2As shown, the driving assembly can further include a pressing plate 21 and a second cylinder 4.

[0098] After the first limiting plate 16 and the second limiting plate 19 limit and fix the battery cell module 12, the second cylinder 4 drives the pressing plate 21 to move downward and contact the battery cell module 12 to fix the battery cell module 12 from the top, further improving the stability of the battery cell module 12 during the cutting process, and improving the precision and effect of the cutting of the battery cell module 12.

[0099] In this embodiment of the present application, as shown in Figure 3 and Figure 5 The grouping and testing device can further include a sliding rail 37, a transfer seat 35, a second ball screw 24, an L-shaped plate 36, and a first pneumatic clamp jaw 34. Specifically, the second ball screw 24 includes a second ball screw body and a second servo motor.

[0100] The sliding rail 37 is arranged at one end of the moving box 10 close to the cutting knife 20, and the transfer seat 35 is in sliding connection with the sliding rail 37. The second ball screw 24 is arranged at the top of the cutting base 22, and the nut of the second ball screw 24 is connected with the transfer seat 35. The L-shaped plate 36 is arranged at one side of the transfer seat 35 close to the moving box 10, and the inner bottom surface of the L-shaped plate 36 is located at the same horizontal plane as the top surface of the moving box 10. The first pneumatic clamp jaw 34 is arranged on the transfer seat 35 and used for clamping and fixing the first battery cell on the L-shaped plate 36. The second ball screw 24 is used to drive the transfer seat 35, which can realize accurate control of the position of the transfer seat 35, and then the subsequent mechanical arm 3 can accurately clamp and move the battery cell on the transfer seat 35. The second servo motor is connected with one end of the second ball screw body.

[0101] When the battery cell module 12 moves to the cutting position, part of the first battery cell enters the inside of the L-shaped plate 36, and then the first pneumatic clamp jaw 34 clamps the first battery cell. When the cutting knife 20 cuts the first battery cell, the cutting knife enters the inside of the first battery cell and the adjacent battery cell, and the first battery cell drives the transfer seat 35 to slightly move on the sliding rail 37 to realize buffering, so as to avoid the battery cell from being deformed and expanded due to excessive pushing force of the cutting knife 20. After the first battery cell is completely cut, the second ball screw 24 drives the transfer seat 35 to slide along the sliding rail 37, so that the cut first battery cell is separated from the battery cell module 12, so as to facilitate subsequent performance detection of the battery cell.

[0102] In this embodiment of the present application, as shown in Figure 3 and Figure 4 The testing assembly can include a testing base 25, two clamping plates 26, two third cylinders 27, a mechanical arm 3, a battery cell contact point recognition assembly, and a battery cell detection assembly.

[0104] After the single electric core is slit, the second ball screw 24 moves the single electric core to the position to be transported, the mechanical arm 3 approaches the electric core, and the second pneumatic clamp jaw 5 clamps the electric core, and finally the mechanical arm 3 moves the electric core to the test base 25. The two third air cylinders 27 are started to drive the two clamping plates 26 to move relatively to clamp the electric core, and then the electric core contact identification assembly identifies the detection contact position on the electric core. After identification, the electric core detection assembly contacts the detection contact and detects the performance of the electric core, and finally determines whether the electric core is a good product or a defective product according to the detection result, so as to be classified and recycled.
