AI Technical Summary

Technical Problem

In the production and inspection of battery cells, there is a lack of a device to check the quality of the welding, especially whether the solder joints are firm and whether there is a false welding.

Method used

A battery cell detection device is designed, including push seat, detection seat combination and spring mechanism. Through the reverse abdication principle of push seat and the elliptical rolling surface of the press wheel, rapid detection of welding quality is achieved.

Benefits of technology

This device not only assists in welding metal sheets, but also quickly verifies the welding quality, improves the working efficiency of spot welding and inspection, and can effectively detect the firmness of the welding joints and whether there is false welding in mass production.

Abstract

The present invention relates to the technical field of battery core welding, and in particular, provides a battery core detection device and detection method. The battery core detection device includes a base, a battery compartment is provided on the base along the length direction, the front and rear sides of the battery compartment are connected, a push seat is provided in the battery compartment, a first carrier plate is provided at the right end of the base, the push seat is located between the first carrier plate and the second carrier plate, a spring is connected between the first carrier plate and the push seat, the push seat is moved to the right close to the first carrier plate by the tensioning action of the spring, and the push seat is moved away from the second carrier plate by the tensioning action of the spring, after the metal sheet is welded to this end of the battery core, the spring quickly releases the elastic force, so that the battery core quickly moves in the opposite direction to complete the rapid detection of the welding quality of the metal sheet. The work efficiency of spot welding and inspection is improved during mass production.
