Film pasting equipment

Abstract

The invention belongs to the technical field of battery manufacturing, and particularly relates to film pasting equipment. The film pasting equipment comprises a rack, two film pressing rollers and two film feeding mechanisms; the rack is provided with a feeding channel and a discharging channel, and a film pasting channel is arranged between the feeding channel and the discharging channel; the two film feeding mechanisms are located on the upper side and the lower side of the film pasting channel respectively; a film pasting opening is formed between the two film pressing rollers; and the film pasting channel penetrates through the film pasting opening. The feeding channel conveys a bare material to the film pasting opening, the two film conveying mechanisms convey insulating films to the film pasting opening respectively, the two film pressing rollers press and paste the insulating films to the front face and the back face of the bare material, and therefore the films are pasted on the front face and the back face of the bare material at the same time, the insulating films can be pasted on the front face and the back face of the bare material without turning over the bare material in the film pasting process, the film pasting equipment does not need to be provided with an overturning mechanism, and therefore the structure of the film pasting equipment is simpler, the equipment operation control difficulty is reduced, and as the procedure of overturning the bare material is omitted, the film pasting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of battery manufacturing, and more specifically relates to a film sticking device. Background technique [0002] Aluminum shell batteries are mainly used in new energy vehicles. Aluminum shell batteries need to be covered with an insulating film on the outside during production to play an insulating role. In the related technology, the aluminum case battery film needs to cut a certain length of insulating film from the film roll, and then use the film roller to roll the insulating film onto the bare aluminum case battery. Since the insulating film needs to cover the front and back of the entire battery, the battery needs to be turned over during the film-attaching process so that the insulating film can be attached to the front and back of the battery. In this way, the film sticking equipment needs to be equipped with a special turning mechanism to turn over the battery. The setting of the turning mechani...
