After a whole cell is divided into multiple slices, it can be placed directly on the cell conveyor belt 1 for transportation. Then the cell conveyor belt 1 will output the cells to the side of the transport mechanism 3. In order to facilitate the transport mechanism 3 For transportation, a detachable barrier 11 is provided at the discharge end of the battery chip conveyor belt 1. The barrier 11 is provided with two symmetrically arranged centering blocks 12. The barrier 11 is used to block the battery cells, and the centering block 12 is used. Allow the battery slices to be centered.

After that, the transport mechanism 3 starts transporting. The transport mechanism 3 includes a frame 31, a steering motor 32 and a mounting bracket 33. The mounting bracket 33 is provided with two diagonally arranged lifting screw slide tables 34. The lifting screw slide table 34 is A vertical plate 341 is installed on the sliding table. A detachable mounting plate 342 is installed at the bottom of the vertical plate 341. A plurality of second adsorption heads 343 are provided on the mounting plate 342. The steering motor 32 is arranged vertically on the frame 31. On the inner top wall, the center of the bottom of the mounting bracket 33 is connected to the output end of the steering motor 32.

The lifting screw slide 34 located above the battery piece drives the slide downward. After that, the vertical plate 341, the mounting plate 342 and all the second adsorption heads 343 move downward simultaneously. The second adsorption head 343 will be positioned at the stopper 11. The battery chips on the side are adsorbed and fixed, and then the lifting screw slide 34 drives the battery chips to move upward, and the battery chips are separated from the conveying surface of the battery chip conveyor belt 1. Then, the steering motor 32 works to drive the mounting bracket 33 to rotate 180 degrees, and the battery The chips are transported just above the regular platform 2, and another lifting screw slide 34 is located just above the battery chip conveyor belt 1. Then the lifting screw slide 34 located directly above the regular platform 2 works again to lift the battery. The battery chip is driven to move downward, and after the battery chip collides with the receiving plate 41, the second adsorption head 343 stops working.

Subsequently, the aligning mechanism 6 begins to align the battery sheets. The first cylinder 62 works to push the first positioning push plate 64 to move. The first positioning push plate 64 pushes the battery sheets to move toward the inner wall of one side of the L-shaped block 61, and then , the second cylinder 63 also works to push the second positioning push plate 65 to move, the second positioning push plate 65 pushes the battery piece to move to the other inner wall of the L-shaped block 61, and finally the first positioning push plate 64 and the second positioning push plate 64 The plate 65 and the L-shaped stopper 61 cooperate to organize the battery pieces, and after the alignment, the battery pieces are adsorbed and fixed by the first adsorption head 9 .

It is worth noting that the receiving plate 41 is driven and moved upward into the window 21 by lifting the electric push rod 8. Before lifting the electric push rod 8, it needs to be docked with the receiving plate 41 through the first adsorption head 9. The first adsorption head 9 includes The adsorption part 91 and the connection part 92 with a polygonal cross-section.

There is an insertion port 413 that is plug-fitted with the connecting portion 92 and communicated with the suction port 411 .

During docking, the adsorption part 91 first enters the insertion port 413 and then reaches the adsorption port 411, and then the connection part 92 is also inserted into the insertion port 413 of the connection socket 412. Since the cross section of the connection part 92 is larger than the cross section of the adsorption part 91, it means that The cross section of the insertion port 413 is larger than the cross section of the suction port 411, so there will be no obstruction when the suction part 91 enters. The polygonal shape of the connecting part 92 can also prevent the connecting part 92 from deflecting.

Further, a third vertical plate 52 is provided on both side walls of the positioning fixture 5. A limit electric push rod 53 is provided on the third vertical plate 52. A limit stop is installed on the output end of the limit electric push rod 53. Block 54.

Before the first adsorption head 9 is docked with the receiving plate 41 , the two limiting electric push rods 53 drive the corresponding limiting stops 54 to translate in the direction of the receiving plate 41 , and then the limiting stops 54 can block the receiving plate 41 , so that The first suction head 9 and the receiving plate 41 will not accidentally shift upward when they are docked.

When the receiving plate 41 accepts the second battery piece, the electric push rod 8 is raised and moved downward by a distance of the thickness of the battery piece. Then, the top surface of the first battery piece on the receiving plate 41 is coplanar with the top surface of the window 21. After each battery piece is arranged to the window 21, the second battery piece will be superimposed on the first battery piece. In this cycle, the battery pieces on the storage base 4 will gradually stack up and become a battery piece, and then remove the lifting electric push rod. The lifting force of 8 is used to correct the deviation of the battery sheet through the first correction mechanism 7. The first correction mechanism 7 includes a correction motor 71, a driving sprocket 72 and a correction blade 73.

When the storage base 4 is placed on all the positioning steps 51 of the positioning fixture 5, the insertion block 711 of the correction motor 71 can be inserted into the first slot 722 at the bottom of the docking shaft 721. At the same time, the resistance block 751 resists the correction On the motor 71, the gravity of the storage base 4 can resist the resistance block 751 and the telescopic rod 75 and move upward. Then the spring 753 is compressed, the teeth 761 on the sector block 76 are staggered with the driving sprocket 72, and then the correction motor 71 starts to work.

When the storage base 4 is removed, the resistance block 751 is lost When the squeezing force is reduced, the spring 753 drives the resistance block 751 to reset through elastic force, and the telescopic rod 75 moves downward. The distance of the downward movement of the telescopic rod 75 can be limited by the limiting piece 752, and then the teeth 761 of the sector block 76 are just stuck in the active position. On the sprocket 72, since the cross-section of the telescopic rod 75 is polygonal, the telescopic rod 75 will not deflect, that is, the driving sprocket 72 is locked, and the four deflection-correcting blades 73 are also locked, so that the battery cells will not deflect during transportation. shift.
