Abstract
The invention provides a battery insulating meson tape and an automatic sticking device. The insulating meson tape includes insulating mesons for attaching the top surface of the battery core cover plate, and the insulating mesons are provided with poles for avoiding the battery core cover plate. pole holes of the pole; the insulating mesons are attached to the upper surface of the adhesive tape at equal intervals, and holes are opened on the adhesive tape at the bottom of the insulating mesons. The automatic pasting device includes the battery cell and the insulating meson tape set on the workbench through the discharge roller. The workbench located in the direction of rotation of the discharge roller is fixed with a bottom paper roller, a cutting device, a take-up roller and a pressing device in sequence. ; The bottom ends of the cutting device and the pressing device correspond to the cell cover plate of the cell. The insulating meson adhesive tape of the present invention coincides with the top surface of the cell cover plate, and is pasted on the cell cover plate by an automatic pasting device, thereby improving the quality and working efficiency of the cell core.
Description
technical field [0001] The invention belongs to the technical field of power battery PACK, and in particular relates to a battery insulating meson tape and an automatic pasting device. Background technique [0002] PACK is the process of making a battery module by combining multiple single lithium batteries in parallel and in series, and finally making a battery pack that meets customer needs. At present, the cell shell is made of aluminum, and the welding slag or other metal objects generated during the PACK process may cause the cell cover to contact the pole, causing a "negative short" problem, which in turn causes lithium ions to react with the aluminum shell, resulting in Shell corrosion leakage. In order to prevent the "negative short" problem of the cell caused by welding slag, it is necessary to attach insulating mesons to the cell cover to eliminate the possibility of contact between the cell cover and the pole. At present, in the actual production process, manual...
