[0030] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0031] This application discloses a handling fixture for battery cells.

[0032] A battery cell handling fixture includes a robotic arm 1, a robotic gripper 2, a cell cassette 4, and a tray 5. The robotic gripper 2 includes a mounting plate 21, a battery cell gripper 22, and a cell cassette gripper 23. The mounting plate 21 is fixedly mounted on the robotic arm 1, and both the battery cell gripper 22 and the cell cassette gripper 23 are mounted on the mounting plate 21.

[0033] After the solar cells are placed on the tray 5, the tray 5 and the solar cells are moved into the cell box 4 by the solar cell clamp 22. Then, the cell box 4 containing the solar cells is moved to the next process by the cell box clamp 23. The solar cell clamp 22 and the cell box clamp 23 are integrated on the mounting plate 21, which saves space for the solar cell handling equipment. The solar cell clamp 22 and the cell box clamp 23 can be switched freely, which improves the convenience of handling solar cells.

[0034] The cell clamp 22 includes a plug-in plate 221 and a pressure plate 222.

[0035] The plug plate 221 and the pressure plate 222 are arranged opposite to each other, and a cell clamping area is formed between the plug plate 221 and the pressure plate 222.

[0036] The plug-in plate 221 is fixedly installed on the mounting plate 21. Several plug-in plates 221 are provided, and all plug-in plates 221 are perpendicular to the mounting plate 21. The tray 5 is provided with plug-in holes 51, and the plug-in plates 221 and plug-in holes 51 are plugged in and mated.

[0037] The pressure plate 222 is mounted on the mounting plate 21, and the pressure plate 222 moves closer to or further away from the plug-in plate 221 via a lifting power source. In this embodiment, the lifting power source is a lifting cylinder, which is fixedly mounted on the mounting plate 21. The pressure plate 222 is fixedly mounted on the push rod of the lifting cylinder, and the pressure plate 222 and the plug-in plate 221 are parallel.

[0038] When handling the tray 5 and the battery cells on it, the connector plate 221 is inserted into the connector hole 51. Then, the pressure plate 222 is moved closer to the connector plate 221, pressing the battery cells firmly onto the tray 5. Simultaneously, to reduce the possibility of excessive pressure on the battery cells applied by the pressure plate 222, which could damage them, a buffer pad 224 is fixedly installed on the side of the pressure plate 222 near the connector plate 221. In this embodiment, the buffer pad 224 is made of rubber. The buffer pad 224 reduces the possibility of the battery cells breaking due to excessive force and also increases the friction between the pressure plate 222 and the battery cells, improving the stability of handling the battery cells.

[0039] To further improve the stability of the transport pallet 5, a limiting groove is provided on the inner wall of the insertion hole 51 near the pressure plate 222, and a limiting block 223 is integrally formed on the side of the insertion plate 221 near the pressure plate 222. The limiting block 223 and the limiting groove are inserted and matched.

[0040] Insert the plug plate 221 into the plug slot. When transporting the pallet 5, move the limiting block 223 toward the limiting slot and insert the limiting block 223 into the limiting slot. The limiting block 223 is limited by the inner wall of the limiting slot, thereby improving the stability of the transporting pallet 5.

[0041] The mounting plate 21 is also equipped with a battery cell detection unit 3. In this embodiment, the battery cell detection unit 3 is a diffuse reflection photoelectric sensor, which detects whether there are battery cells on the tray 5.

[0042] The tablet cassette gripper 23 includes a hook 231 and a tablet cassette balancing unit 232.

[0043] The hook 231 is fixedly installed on the mounting plate 21, and the length direction of the hook 231 is perpendicular to the mounting plate 21. In this embodiment, two hooks 231 are provided opposite each other.

[0044] A placement rod 41 is fixedly installed on the outer side wall of the disc box 4. The placement rod 41 can be placed inside the hook 231 and rotates with the hook 231.

[0045] Multiple cartridge balancing units 232 are provided. In this embodiment, two cartridge balancing units 232 are provided. Both cartridge balancing units 232 are mounted on the mounting plate 21 and are distributed diagonally along the cartridge 4.

[0046] The cartridge balancing unit 232 includes a telescopic rod 233 and a balancing plate 234.

[0047] The telescopic rod 233 has the same length direction as the hook 231. One end of the telescopic rod 233 is fixedly installed on the mounting plate 21. In this embodiment, the telescopic rod 233 is a telescopic cylinder. The balance plate 234 is fixedly installed on the end of the push rod of the telescopic cylinder. The balance plate 234 is used to contact the cassette 4.

[0048] After placing the placement rod 41 inside the hook 231, the telescopic rod 233 pushes the cell box 4 through the balance plate 234, keeping the cell box 4 in a vertical position for a long time. This reduces the possibility of the cell box 4 shaking during the handling process and further improves the stability of handling the battery cells.

[0049] The implementation principle of a battery cell handling fixture in this application embodiment is as follows: After the battery cell is placed on the tray 5, the battery cell gripper 22 is brought close to the tray 5 by the robotic arm 1, and the plug plate 221 is inserted into the plug hole 51. Then, the diffuse reflection photoelectric sensor checks whether there is a battery cell on the tray 5. After detecting that there is a battery cell on the tray 5, the pressure plate 222 is moved so that the pressure plate 222 moves closer to the plug plate 221, and the battery cell is pressed tightly on the tray 5 by the buffer pad 224. Then, the robotic arm 1 drives the battery cell gripper 22 to move, and the tray 5 and the battery cell are placed into the cell box 4 as a whole. Next, the plug plate 221 is detached from the plug hole 51. The mounting plate 21 and hook 231 are moved so that the placement rod 41 on the side wall of the cell box 4 is placed on the hook 231. The overall length of the telescopic cylinder is adjusted so that the balance plate 234 on the telescopic cylinder contacts the top of the cell box 4. This keeps the cell box 4 in a vertical position during the overall transportation process, thereby improving the stability and convenience of transporting the cell box 4 and the battery cells.

[0050] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
