Polar plate processing method of accumulator

Abstract

The invention discloses a processing method of the polar plate of a storage battery. Firstly, lead paste is coated on a grid; secondly, the grid coated with the lead paste is solidified and dried to form a multi-piece-link polar plate; thirdly, the multi-piece-link polar plate is cut and when cutting, each multi-piece-link polar plate is put into a milling machine independently; two opposite milling cutters at the vertical direction of the milling machine cut the multi-piece-link polar plate vertically to produce a single-piece polar plate and after cutting, the milling cutters are separated in a certain distance to brush the surface of the tab of the polar plate. The polar plate with tabs of the same length and the same thickness is produced by the milling machine with the working characteristic of high precision. The original cutting and brushing procedures are finished by the milling machine in one step, which shortens process flow, prevents the quality of the product from being affected by the processing operation of different precisions and improves the qualification rate of products. Besides, the appearances of chip shell, fault soldered joint, lead leakage, etc. occured during the original polar plate welding do not exist and the service life is prolonged.

Description

A kind of pole plate processing method of storage battery technical field The invention relates to a method for processing pole plates of storage batteries. Background technique In the production of battery plates, multiple plates are stacked and cut into individual pieces with a high-speed rotating saw blade, so multiple small pieces can be obtained in one cut, and then the surface of the tabs of the plates is brushed with a wire brush to remove the poles. The oxide layer on the surface of the ear. Due to the low cutting accuracy of the saw blade, the lug lengths of the pole plates obtained by cutting are inconsistent; the grinding process of the wire brush is manually controlled, and the degree of force is different for each operation, so the grinding degree of each pole plate is not the same, resulting in Tab thickness is uneven. When the plate is welded, it is easy to have plate drop, false welding, lead leakage and other phenomena, which will cause a short circuit o...

Problems solved by technology

Due to the low cutting accuracy of the saw blade, the lug lengths of the pole plates obtained by cutting are inconsistent; the grinding process of the wire brush is manually controlled, and the degree of force is different for each operation, so the grinding degree of each pole plate is not the same, resulting in Uneven tab thickness

When the plate is welded, it is easy to cause the plates to fall off, virtual welding, lead leakage, etc., which will cause a short circuit of the battery.
