Laminating equipment

Abstract

The invention belongs to the technical field of battery manufacturing, and in particular relates to a film sticking device. The film laminating equipment includes a frame, two film pressing rollers and two film feeding mechanisms; the frame is provided with a feeding channel and a discharging channel, and there is a film bonding channel between the feeding channel and the discharging channel; the two film feeding mechanisms are respectively located on the upper and lower sides of the film bonding channel. On the side, there is a film laminating port between the two laminating rollers, and the film laminating channel runs through the film laminating port. The feeding channel transports the bare material to the film laminating port, the two film feeding mechanisms transport the insulating film to the film laminating port respectively, and the two film pressing rollers press the insulating film to the front and back sides of the bare material, so as to realize the front and back sides of the bare material at the same time Film application, the insulating film can be pasted on the front and back of the bare material without flipping the bare material during the film sticking process. The film sticking equipment does not need to be equipped with a turning mechanism, the structure of the film sticking equipment is simpler, the difficulty of equipment operation control is reduced, and it reduces the need to turn over the bare material. The process improves the efficiency of film sticking.

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...
