Assembly processing method of SC battery

Abstract

The invention provides an assembly processing method of an SC battery. The assembly processing method sequentially comprises the following steps of winding a pole shank; welding a collector plate, wherein the concentricity of the pole shank and the collector plate is within 0.2mm, welding points are 8 to 12, and the welding tension is not less than 20N; loading the pole shank into a shell; mounting a protective ring: embedding, by a manipulator, the protective ring between the battery shell and the collector plate; slot rolling: wherein the width of a groove is 3mm to 5mm, and the depth of thegroove is 1.2mm to 1.6mm; asphalt coating; electrolyte injection and centrifugation: injecting an electrolyte into the battery shell and realizing centrifugal operation by an electrolyte injection and centrifugation device; cap welding, wherein the welding tension is not less than 15N; cap pressing; sealing. The assembly processing method can be used for preventing the collector plate and the battery shell from generating a short circuit; thus, the performance of the SC battery is effectively ensured; the made SC battery is stable in structure and high in sealability, and further, has higherresistance; the service life of the battery is long; the assembly processing efficiency is high, and the quality consistency of SC batteries made in a batch manner is high.

Description

technical field [0001] The invention relates to an SC battery processing method, and specifically discloses an SC battery assembly processing method. Background technique [0002] The height of the SC battery is 42.0mm, and the diameter is 22.1mm. SC is the model of the battery. The SC battery is a cylindrical battery, mostly a nickel-hydrogen battery. Traditional nickel-metal hydride batteries are assembled manually, which has high labor costs, low assembly efficiency, uneven assembly quality, and high defective rate. For the current market, the quality of mass-produced batteries cannot be consistent. Seriously affect the competitiveness of products. [0003] Some existing manufacturers use automated devices to assemble batteries, mainly including winding, welding collector trays, shelling, rolling grooves, liquid injection, and welding caps. The disk is easy to contact with the battery shell, which will affect the normal use of the battery, and may even cause a short cir...

Traditional nickel-metal hydride batteries are assembled manually, which has high labor costs, low assembly efficiency, uneven assembly quality, and high defective rate. For the current market, the quality of mass-produced batteries cannot be consistent. Seriously affect the competitiveness of the product

[0003] Some existing manufacturers use automated devices to assemble batteries, mainly including winding, welding collector trays, shelling, rolling grooves, liquid injection, and welding caps. The disc is easy to come into contact with the battery shell, which will affect the normal use of the battery, and may even cause a short circuit to make the battery scrapped. The structure of the molded battery is loose, and it is easy to shorten the service life of the battery.
