Problems solved by technology

[0004] At present, the traditional film winding machine adopts double-needle film winding. The two film winding needles are cut from a round rod and formed into a flat shape. The cost is extremely high; and due to the strength problem during production, often There will be bending and breaking of the needle, which will directly lead to the increase of production cost and the reduction of product quality

Abstract

The invention discloses a method for preparing battery roll cores by automatic film winding. The method comprises the following steps: (1) arranging an automatic film winder which comprises a lower pressing wheel, an upper pressing wheel group, a film winding needle, a film winding platform and a transmission gear, wherein the film winding needle is arranged between the upper pressing wheel group and the lower pressing wheel, the film winding platform is arranged on the lower pressing wheel, and the transmission gear is connected to the components; and (2) switching on the power, the automatic film winder is at a working state, diaphragm paper is arranged on the film winding platform, a negative plate is arranged on the diaphragm paper, and the lower pressing wheel is lifted under the driving of the transmission gear; the diaphragm paper is overturned and folded so as to wrap the film winding needle, a positive plate is arranged on the diaphragm paper, and the upper pressing wheel group is descended under the driving of the transmission gear; the transmission gear is used for driving the film winding needle to rotate so as to realize the winding production of the battery roll cores. The invention also discloses the automatic film winder for realizing the method.

Description

technical field [0001] The invention relates to the technical field of battery manufacturing, in particular to a method for automatically winding sheets to prepare battery winding cores and an automatic sheet winding machine for implementing the method. Background technique [0002] Ni-MH battery is an alternative to the early nickel-cadmium battery. It is currently a more environmentally friendly battery. It does not use toxic cadmium and can eliminate the pollution of heavy metal elements to the environment. Ni-MH batteries have a large energy density ratio, which means that the use of Ni-MH batteries can effectively extend the working time of the equipment without adding extra weight to the digital equipment. At the same time, nickel-hydrogen batteries are basically similar to nickel-cadmium batteries in terms of electrical characteristics, and can completely replace nickel-cadmium batteries in practical applications without any modification of equipment. Another advanta...
