[0044] Embodiment 2:

[0045] Based on the first embodiment, the specific working principle is as follows:

[0046] Loading:

[0047] Battery cells: The workpiece battery cells are placed in the storage trough 1 in the specified direction. The material-pickup mechanism 2 below the trough peels off one battery cell at a time, and the rear is guided to the first conveyor line 3 through the guide channel;

[0048] Capping: Manually place the TRAY on the storage rack 4, neatly in sequence, and place 10 layers. The material-retrieving robot 5 takes one TRAY at a time and puts it in the material-retrieving position through the material-retrieving robot 5. The handling robot 6 absorbs a row of caps and puts them on the second conveyor line 7. After the TRAY tray caps are taken, the material-retrieving robot 5 puts the TRAY tray back to the original layer and continues to take the next layer of TRAY tray;

[0049] Loading boxes: 6 boxes are manually stacked on the third conveyor line 8, and the box sorting mechanism 9 sorts one box onto the conveyor line, and the conveyor line transports the sorted boxes to the docking mechanism 10;

[0050] Welding positioning:

[0051] Battery cell: The pushing cylinder pushes the battery cell onto the positioning fixture of the welding line 11; the welding line 11 moves a first position detection mechanism 12 to detect the height of the battery cell pole ear. If the height is not enough, it is judged as a defective product and no action is taken on the battery cell in the future; the welding line 11 continues to move a first angle adjustment mechanism 13 cylinder extends, and the first angle adjustment mechanism 13 motor rotates until the battery cell pole ear reaches the position required for welding; the welding line 11 moves a position, the first shaping mechanism 14 descends, the shaping clamp clamps the battery cell pole ear, and the lifting cylinder straightens the pole ear upward; the welding line 11 moves a position, the arranging mechanism 15 clamps the pole ear, and the clamp clamps the pole ear, and the pressing mechanism is pressed down to press the pole ear down to the predetermined welding height, and the clamp and the clamping mechanism are released at the same time, and the welding line 11 moves a position;

[0052] Capping: The cylinder of the pushing mechanism 16 pushes the cap onto the positioning fixture of the positioning line 17; the second position detection mechanism 18 detects the height of the cap ear, and if the height is not enough, it is judged as a defective product, and no capping action will be taken subsequently; the positioning line continues to move, and the cylinder of the second angle adjustment mechanism 19 extends, and the motor of the second angle adjustment mechanism 19 rotates until the cap ear reaches the position required for welding; the welding line 11 moves one position, the second shaping mechanism 20 descends, the shaping clamp clamps the cap ear, and the cylinder straightens the ear upward; the positioning line moves one position, and the cap dividing mechanism 21 pushes the cap away to flip to the flip feeding mechanism 22; flip to the flip feeding mechanism 22, and the cylinder of the welding positioning mechanism 23 extends to push the cap away from the flip mechanism to the welding position for welding;

[0053] After welding:

[0054] After the cap is welded to the battery cell, the welding line 11 moves to one position. When all the welded products have reached the unloading position, the main unloading mechanism 24 pushes the cylinder onto the battery cell unloading line 25. If the front end determines that it is a defective product, the defective product unloading mechanism 26 pushes the defective product to the defective collection line 27. If it is a good product, it remains on the unloading line. After the number of finished battery cells reaches 5 at the end of the unloading line, the unloading robot 28 clamps 5 battery cells and puts them into the loading box. After the box is full, the connecting mechanism descends to the full material conveyor line position inside the chassis and conveys the box to the full material conveyor line. After the box of the conveyor line meets the requirements, the machine alarms to prompt the person to take the box away.

[0055] Embodiment three:

[0056] Based on the first and second embodiments, the specific working principle is as follows:

[0058] like Figure 3 As shown, the tray separation cylinder drags a stack of trays. When separating the trays, the tray cylinder descends to put the stack of trays on the production line. The tray separation cylinder retracts. After the tray cylinder retracts, the tray separation cylinder extends to separate the upper material tray from the lower material tray. When the production line moves, the lower material tray is pulled out.

[0059] like Figure 4As shown, when the empty material box is at the end of the flow line, it is transported to the connecting belt, and the connecting belt starts to transport the material box to the box loading location.

The unloading mechanism pushes the battery cell of the welding line 11 to the loading position of the battery cell unloading line. If it is a defective product, the defective product unloading mechanism retracts and pushes the defective product to the defective product collection line. If it is a good product, it is directly transported downward.
