[0022] like Figs. 1-3 As shown, a battery cell replacement auxiliary device, the battery cell to be replaced includes a number of alternating positive and negative plates, and the positive and negative plates are separated by a diaphragm. The battery cell replacement auxiliary device includes a base 1, the base 1 is a flat plate, and the upper surface of the base 1 is provided with a long support plate 2, and the support plate 2 is placed in the middle area of the upper surface of the base 1. The base 1 serves as the foundation of the entire device, ensuring the stability of the structure and providing solid support for the structure above, so that the entire device remains stable during operation, thereby ensuring the safety and accuracy of the operation. The support plate 2 is fixed in the middle position of the base 1. The support plate 2 is the main support surface for the placement of the battery cell. The design of the support plate rationally utilizes the space, so that the operating area is concentrated and easy to control.
[0023] A fixed plate 3 and side baffles 4 are fixed to either side of the support plate 2. The fixed plate 3 is arranged vertically, while the side baffles 4 are arranged at an angle. The bottom edge of the side baffles 4 is parallel to the bottom edge of the fixed plate 3, and the side baffles 4 gradually extend outward away from the fixed plate 3 from bottom to top. A space for accommodating battery cells is formed between the side baffles 4 and the fixed plate 3. Together, the fixed plate 3, side baffles 4, and support plate 2 form a space that serves as a cell-changing slot. This design fully considers the cell shape and the requirements of cell-changing operations, ensuring stable placement of the cells during cell-changing while facilitating cell-changing operations from the side of the fixed plate 3.
