Problems solved by technology

[0002] In the production process of the battery, in order to prevent bruising and insulation, it is necessary to use the protective film for wrapping; currently, the use of film wrapping equipment cannot effectively eliminate the defects on the protective film caused by factors such as the production environment, processing technology and production equipment. Wrinkles prevent the protective film from completely covering the side of the battery. At this time, manual participation of the staff is required. The processing efficiency is low, which not only affects the electrochemical performance of the battery cell, but also affects the appearance of the battery cell.

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0035] refer to Figure 10 As shown, a battery winding process includes the following steps:

[0036] Obtain the center line in the length direction of the battery and the center line in the length direction of the protective film, and place the center line in the length direction of the battery and the center line in the length direction of the protective film in an overlapping manner;

[0037] Hot press one end of the protective film on the starting end of the first side of the battery, and leave a length of starting film, pull the protective film so that the protective film is attached to the lead side and the second side of the battery in sequence, heat the protective film pr...

Abstract

The invention relates to the technical field of battery processing, and relates to a battery film winding process and equipment. One end of the protective film is hot-pressed on the starting end of the first side surface of the battery, the protective film is sequentially wound on each side surface of the battery by driving the battery to rotate, and the protective film is gradually wound on the battery by utilizing a segmented and multi-time high-temperature hot-pressing technology, so that wrinkles of the protective film are effectively avoided; the film is wound by driving the battery to rotate without repeated pressing in the later period, so that the quality of the protective film is ensured; and meanwhile, the central lines of the battery and the protective film in the length direction are overlapped and wound, so that the condition that the central lines of the battery and the protective film in the length direction deviate in the film winding process is effectively avoided, the film winding precision is improved, and the film winding quality is ensured.
