Electrode plate wrapping method

Abstract

The invention relates to an electrode plate wrapping method, which comprises the steps of: first, arranging a positive electrode plate and a negative electrode plate in an electrode plate material box vertically respectively, above all using a sucking disc to suck the positive electrode plate laterally, then turning the positive electrode plate downward by 90 degrees and placing it in a material trough, moving the positive electrode plate placed in the material trough forward by one working position, at the same time moving separator paper from top to bottom, cutting the separator paper off and disposing it on the material trough vertically, further moving the positive electrode plate forward by one working position, and making the front end of the positive electrode plate contact the central part of the separator paper in the moving process, along with the forward moving of the positive electrode plate, wrapping the positive electrode plate with the separator paper, then further moving the positive electrode plate forward by one working position, simultaneously employing the sucking disc to suck a negative electrode plate laterally, and placing the negative electrode plate right over the wrapping completed positive electrode plate, then keeping moving the negative electrode plate, the separator paper, and the positive electrode plate forward into a material receiving device, and when the number of a plate pack is collected, sending the plate pack out.

Description

Technical field [0001] The invention relates to the technical field of battery production, in particular to a method for wrapping battery plates. Background technique [0002] In the production process of battery assembly, there is a process in which the positive and negative plates in the battery are first wrapped with separator paper, and then one positive and one negative are overlapped, forming a pole group according to the required number of positive and negative. The traditional method is to make by hand. Put a piece of separator paper, another plate, fold the separator paper, put another separator paper, put a plate, and then fold the separator paper..., or Through the indentation mechanism, the indented separator paper is scraped off one by one with the pole plate to form a pole group. The production efficiency is low and the health hazards of the operators are greater. [0003] At present, some companies have developed a plate wrapping machine that can automatically wrap...

Problems solved by technology

When using the above-mentioned pole plate wrapping machine to wrap the pole plate, because the thickness of the pole plate is different, and the pole plate itself will have unevenness, when the pushing mechanism pushes the pole plate located at the bottom, it will The situation of pushing two polar plates at a time causes errors in the subsequent process; at present, the conveyor belt is usually used to realize material transfer, but when the conveyor belt starts and stops, the polar plates are inevitably on the conveyor belt under the action of inertia. Sliding occurs on the top, which affects the accuracy of movement; and its receiving mechanism can usually only complete the superposition of the plates, but it cannot realize a group of automatic receiving after being superimposed into a pole group, and it can only be done manually. Extremely group receiving, low work efficiency, and easy to cause harm to workers' health
