The utility model can insert the transverse guide plate and the guide plate into the corresponding longitudinal through groove or transverse through groove, so that the central rectangular placement cavity formed in the middle thereof cooperates with the mounting frame of the lithium battery cell to be assembled, so that the lithium battery cell to be assembled can be inserted into the central rectangular placement cavity, making it easy to arrange and install, and convenient for the subsequent installation of the mounting frame. The lithium battery cell is not easy to flip over during installation, and the effect is good. However, after the lithium battery cell is placed, the above-mentioned arrangement auxiliary tooling requires the worker to manually press the upper mounting frame downward so that the upper mounting frame fixes the upper end of the lithium battery cell, which is not conducive to saving the worker's effort and is prone to the phenomenon of the upper mounting frame tilting, increasing the workload in the subsequent lithium battery assembly process. The height of the above-mentioned arrangement auxiliary tooling cannot be adjusted according to the worker's operating habits, which affects the worker's comfort in assembling the lithium battery, and thus affects the assembly efficiency of the lithium battery. Therefore, in order to solve the above-mentioned problems, the utility model proposes a cell arrangement auxiliary device for assembling lithium batteries. Utility Model Content
