[0048] The working mode of the utility model of a kind of buckle electricity assembly equipment is as follows:

[0049] First, material moving device 2 acts, so that each vacuum suction head 221 of the material moving carousel 22 of material moving device 2 is respectively first adsorbed first pole shell, second pole shell, auxiliary material, lithium sheet, diaphragm and pole piece placed on one material fixture 31 of material device 3;

[0050] Second, material moving device 2 acts, and first pole shell, second pole shell, auxiliary material, lithium sheet, diaphragm and pole piece adsorbed by material moving device 2 all pass through material visual identification device 7, and material visual identification device 7 carries out material contour identification to first pole shell, second pole shell, auxiliary material, lithium sheet, diaphragm and pole piece adsorbed by material moving device 2 to confirm the center position of first pole shell, second pole shell, auxiliary material, lithium sheet, diaphragm and pole piece adsorbed by material moving device 2 and record;

[0051] Third, material moving device 2 acts, and first pole shell, auxiliary material and lithium sheet adsorbed by material moving device 2 are sequentially stacked in assembly fixture 41 of assembly device 4;

[0052] Third, assembly translation driving device 42 of assembly device 4 drives assembly fixture 41 to translate to liquid injection device 5, and liquid injection device 5 injects electrolyte into lithium sheet to carry out first injection, after first injection is completed, assembly translation driving device 42 of assembly device 4 drives assembly fixture 41 to translate reset;

[0053] The fourth step is that the material moving device 2 places the diaphragm adsorbed by the material moving device 2 to the assembly jig 41 of the assembly device 4; then the assembly translation driving device 42 of the assembly device 4 drives the assembly jig 41 to translate to the liquid injection device 5, the liquid injection device 5 injects electrolyte into the diaphragm to perform the second liquid injection, after the liquid injection is completed, the assembly translation driving device 42 of the assembly device 4 drives the assembly jig 41 to translate to reset;

[0054] The fifth step is that the material moving device 2 acts, so that the material moving device 2 places the pole piece and the second pole shell adsorbed by the material moving device 2 to the assembly jig 41 of the assembly device 4 in sequence; after the placement of the second pole shell is completed, the material moving device 2 can press the second pole shell to make the second pole shell pre-press with the first pole shell; then the assembly translation driving device 42 of the assembly device 4 drives the assembly jig 41 to translate to the pressing device 6, the pressing device 6 completely presses the second pole shell with the first pole shell, after the complete pressing is completed, the assembly translation driving device 42 of the assembly device 4 drives the assembly jig 41 to translate to reset.

Furthermore, this invention utilizes a material vision recognition device 7 to identify the material contours of the first electrode shell, second electrode shell, auxiliary material, lithium sheet, separator, and electrode sheet adsorbed by the transfer device 2. This allows for confirmation of the center positions of the first electrode shell, second electrode shell, auxiliary material, lithium sheet, separator, and electrode sheet adsorbed by the transfer device 2. Consequently, the transfer device 2 can be controlled to place the first electrode shell, auxiliary material, lithium sheet, separator, electrode sheet, and second electrode shell onto the assembly fixture 41. This ensures the concentricity of the first electrode shell, auxiliary material, lithium sheet, separator, electrode sheet, and second electrode shell placed by the transfer device 2 onto the assembly fixture 41.
