Abstract

The invention provides a thermal shrinkage film heating mechanism which is used in a thermal shrinkage process of a battery and comprises a conveying device, a rotary base, a liquid storage part and aresistance piece. The rotary base is rotatably arranged on the conveying device, and the top of the rotary base is used for arranging the battery. The liquid storage part is provided with an inner cavity used for storing a heating medium and is arranged above the conveying device, and a through groove allowing the battery to penetrate through is formed in the bottom of the liquid storage part. The resistance piece is arranged at one side of the moving track of the rotary base and is configured in such a way that when the rotary base moves to the position of the through groove, the resistancepiece can make contact with the edge of the rotary base so as to rotate the rotary base. By adopting the thermal shrinkage film heating mechanism provided by the invention, the heating effect of a battery thermal shrinkage process is greatly improved, the quality and the strength of a finished sleeve film are improved, wrinkles or cracks of the sleeve film are avoided, and the appearance of the battery product is effectively prevented from being influenced by the thermal shrinkage problem of the sleeve film.

Description

technical field [0001] The invention relates to the technical field of secondary battery manufacturing, in particular to a heat shrinkable film heating mechanism. Background technique [0002] During the production process of the battery, heat-shrinkable film should be put on the outside of the battery for heat-shrinkage fastening, so that the heat-shrinkable film can be tightly combined with the bare battery. In the prior art, the method of electric heating and blowing heat is usually used to make the heat-shrinkable film shrink when exposed to heat, so as to tightly cover the outside of the battery. In actual production, due to the uneven heating surface of electric heating and blast heat dissipation, the battery is heated unevenly during the heat shrinking process, which eventually leads to poor heat shrinking effect of the heat shrinkable film and poor quality of the finished film. The strength is low, and the film is prone to wrinkles or cracks, which affects the appea...
