Annular conveying mechanism for assembling cylindrical lithium ion battery cap assembly

Abstract

The invention discloses an annular conveying mechanism for assembling a cylindrical lithium ion battery cap assembly. The annular conveying mechanism comprises a machine table, and is characterized in that a servo motor indexing plate, a transmission chain wheel set and an annular transmission chain which is tensioned by the transmission chain wheel set are arranged on the machine table; the transmission chain wheel set comprises a driving chain wheel, a driven chain wheel and a plurality of tensioning chain wheels, wherein the driving chain wheel, the driven chain wheel and the plurality of tensioning chain wheels are arranged on the machine table, and the servo motor indexing plate is connected with the driving chain wheel; and the annular conveying mechanism further comprises a plurality of elastic clamping mechanisms which are uniformly fixed to the transmission chain at intervals and are used for clamping the cap assembly, the elastic clamping mechanisms comprise positioning plates, cap assembly positioning holes and two spring clamping block devices, wherein the cap assembly positioning holes are formed in the positioning plates, the two spring clamping block devices are symmetrically arranged on the left and right sides of the cap assembly positioning holes, and are used for clamping the cap assembly, and the cap assembly positioning holes are internally provided with concave tables for bearing the cap assembly. The annular conveying mechanism can take place of manual work to reliably convey the cap assembly among assembly working positions, the efficiency is improved, the cap assembly positioning stability is high, and the transmission precision is high.

Description

technical field [0001] The invention relates to an annular conveying mechanism for assembling a cap assembly of a cylindrical lithium ion battery. Background technique [0002] It is generally known in the industry that the cap is the core component of the cylindrical lithium-ion battery, which is related to the safety of the cylindrical lithium-ion battery. At present, the caps of cylindrical lithium-ion batteries widely sold on the market are usually composed of explosion-proof plate 1, top cover 2, orifice plate 3 (aluminum plate), orifice plate gasket 4 and sealing ring 5. The details are as follows: image 3 As shown, the assembly relationship of these five components is: the top cover 2 is welded and fixed on the top surface of the explosion-proof disk 1, the orifice gasket 4 is placed on the bottom surface of the explosion-proof disk 1, the orifice plate 3 is placed on the orifice gasket 4 and connected with the explosion-proof disk 1, the bottom surface is welded, an...

Problems solved by technology

[0004] 1) The transfer of cap components between stations lacks reliable and effective conveying equipment. At present, it is still mainly done manually, but manual transfer is time-consuming and labor-intensive, which is not only inefficient, but also prone to deviations, resulting in production stagnation

[0005] 2) There is a lack of good transfer carriers for the cap components, and the transfer carriers between different stations are often replaced, which cannot be well matched and adapted to each station equipment, resulting in poor positioning stability for the cap components and matching accuracy during assembly Not high, yield rate drops

[0006] Obviously, the existence of the above problems has greatly hindered the development and application of the current assembly process of cap components by cylindrical lithium-ion battery cap manufacturers.
