Abstract

The invention discloses storage battery busbar welding quality detection equipment, belongs to the technical field of detection, and aims to improve busbar welding quality. According to the technicalscheme, the equipment comprises an equipment frame body, a detection control circuit, and a storage battery conveying device, a detection head and a three-dimensional detection position adjusting mechanism which are connected with the detection control circuit. The storage battery conveying device and the equipment frame body are fixed together, a to-be-detected storage battery is placed at the upper part of the storage battery conveying device, and the detection head is connected with the equipment frame body through the three-dimensional detection position adjusting mechanism and correspondsto a busbar of the to-be-detected storage battery on the storage battery conveying device. By means of the equipment, through-wall welding quality is detected by detecting the internal resistance between the two groups of polar group busbars, automatic and online detection of all products is achieved, compared with traditional manual destructive sampling inspection, the equipment eliminates the missing inspection phenomenon, the welding quality of the busbar can be guaranteed, the labor intensity of workers can be reduced, the detection efficiency is improved, and the detection cost is reduced.

Description

technical field [0001] The invention relates to a device capable of automatically detecting the quality of through-wall welding of battery electrode group busbars, and belongs to the technical field of detection. Background technique [0002] During the assembly and production of battery pole groups, the through-wall welding quality of pole group busbars between two adjacent grids is a key factor affecting the quality of batteries. The principle of through-wall welding is butt resistance welding. Its working process is: place the busbars of the two pole groups of the battery between the two electrodes of the through-wall welding machine, and make a strong current pass through the butt joint under the action of pressure. Use the heat generated by the contact resistance of the two bus bars to partially melt and plasticize them. After the power is turned off, a permanent and firm welding point will be formed under continuous pressure. The two sets of pole groups can be connecte...
