The invention relates to the technical field of batteries, and discloses a method for forming a battery top cover, including steps: 1), providing a cover plate and two poles; 2), passing a pole body through the cover plate, and inserting the pole Put the cover plate in the first mold, inject conductive plastic in the first mold, the conductive plastic forms a conductive plastic ring, and the combination of the pole and the cover forms a single pole semi-finished product; pass the cylinder of the other pole through Cover plate, put the combination of the other pole and the semi-finished single pole into the second mold, inject insulating plastic into the second mold, the insulating plastic forms an insulating plastic ring, and the combination of the other pole and the semi-finished single pole 3) Place the semi-finished bipolar column in the third mold, inject plastic into the third mold, and mold two plastic plates under the cover plate. The method of injection molding in the mold forms the battery top cover, reduces the parts of the battery top cover, has low molding cost, simple structure, and is easy to realize mass production.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a method for forming a battery top cover. Background technique [0002] At present, with the increasing miniaturization, portability and portability of electronic products, such as cameras, notebooks and mobile phones, the driving power of these electronic products is also developing in the direction of high capacity, high safety and portability. Excellent characteristics such as high capacity are widely used in electronic products; in addition, batteries are also widely used in new energy vehicles. [0003] The battery includes a casing, a battery top cover, and a battery cell, etc., wherein the battery cell is placed inside the casing, the upper end of the casing has an upper end opening, and the battery top cover closes the opening at the upper end of the casing, and then passes through the opening formed on the top of the battery. The poles on the cover can electrically co...
