Automatic welding work station of battery module

Abstract

The invention discloses an automatic welding work station of a battery module. The automatic welding work station comprises an assembly line for conveying a battery module to be welded, and a laser washing device, at least one laser welding device and an after-welding detection device which are arranged in sequence along an operation direction of the assembly line, wherein the laser washing deviceis arranged beside the assembly line and is located at an entrance of the assembly line; the laser washing device is used for carrying out laser washing on the battery module to be welded; the laserwelding devices are symmetrically arranged at two sides of the assembly line, are located between the laser washing device and the after-welding detection device and are used for welding a battery cell electrode column on the battery module and a module bus bar; the after-welding detection device is arranged at two sides of the assembly line and is located at one end far away from the laser washing device; the after-welding detection device is used for detecting whether the quality is qualified or not after welding is finished. Compared with traditional module welding equipment, the automaticwelding work station has the characteristics of relatively high automation degree, working efficiency, welding yield and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of laser welding, in particular to an automatic welding workstation for battery modules. 【Background technique】 [0002] Lithium battery is a new generation of green high-energy battery with excellent performance, because it has the characteristics of high voltage, high capacity, low consumption, no memory effect, pollution-free, small size, low internal resistance, less self-discharge, and many cycles. It is widely used in automobile power batteries, mobile phones, notebook computers, tablet computers and many other civilian and military fields. [0003] Cylindrical power batteries are sought after by many new energy automobile companies and power battery companies because of their stable performance and cheaper prices than square and soft pack batteries. However, the capacity of a single cylindrical battery is relatively low, so generally dozens or even hundreds of single cylindrical batteries are com...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the main purpose of the present invention is to solve the problem of unsatisfactory cleaning effect due to the unsatisfactory cleaning effect caused by the manual cleaning of the existing cylindrical modules before welding, as well as the low efficiency of the welding process and the low welding connection strength. , it is impossible to timely detect defects such as explosion spots, welding penetration, and weld width in welded workpieces, resulting in low production efficiency and automation, and technical problems such as inability to meet the production needs of large-scale cylindrical modules.
