The assembly of a lithium ion battery generally refers to the process of assembling positive and negative pole pieces, a diaphragm, a pole lug, a shell and other components into the battery. The assembly process can generally be divided into winding and lamination, assembly, welding, etc. The winding and lamination are processes of manufacturing the positive and negative pole pieces welded with the lugs on the current collector and the diaphragm into a square or cylindrical battery core structure with a positive-diaphragm-negative pole structure. The process flow of the full-automatic lamination machine is that the positive and negative pole pieces are positioned and then are transmitted to a lamination table, and the diaphragm is also introduced into the lamination table after being unreeled from a material roll; the pole pieces are accurately positioned and then are sequentially stacked on the lamination table, the diaphragm moves left and right in a reciprocating mode to form a positive electrode/diaphragm/negative electrode lamination structure, after lamination is completed, glue is automatically pasted, and after lamination is completed, the lamination is sent to the next procedure.

After the existing client battery completes the lamination process, the existing adhesive tape sticking equipment sticks 10 groups of adhesive tapes on the diaphragm, the battery core is limited by the need of positioning during the adhesive tape sticking, the mechanical structure interferes at an ideal adhesive tape sticking position, as shown in fig. 1, four groups of upper side
