AI Technical Summary

Technical Problem

Existing technologies make it difficult to achieve precise welding positioning of MOS tubes on highly integrated energy storage boards. Especially under the requirements of different equipment shapes and sizes, automated welding equipment cannot meet personalized welding positioning requirements, and welding quality consistency and efficiency are difficult to guarantee.

Method used

A soldering fixture is designed to control the height of MOS tubes on battery energy storage boards. The fixture includes a base plate, a positioning plate, and a cover plate. An elastic support mechanism is used to lift the MOS tubes from under the circuit board, and the circuit board pressure columns at the bottom of the cover plate provide uniform pressing force to ensure that the MOS tubes are at the same level.

Benefits of technology

It achieves precise product positioning of battery energy storage panels with complex structures, improves production efficiency, reduces welding quality anomalies, and ensures consistency of batch welding quality.

Abstract

The soldering tin clamp capable of controlling the height of the MOS tube of the battery energy storage plate comprises a bottom plate, a positioning plate and a cover plate, a plurality of elastic supporting mechanisms are arranged on the bottom plate, and a plurality of circuit board pressing columns are arranged at the bottom of the cover plate. According to the utility model, the MOS tube is jacked up from the lower part of the circuit board of the MOS tube to be welded through the elastic supporting mechanism, and uniform downward pressing force is provided on the circuit board through the circuit board pressing columns at the bottom of the cover plate, so that the circuit board is prevented from tilting while the circuit board is pressed and fixed; therefore, the MOS tube parts to be welded on the circuit board can be kept at the same horizontal height. According to the utility model, accurate product positioning can be carried out on the battery energy storage plate with a complex structure and strict requirements on the welding height of the MOS tube, the MOS tube parts on the circuit board can be controlled in a to-be-welded state with the required assembly height, the production efficiency can be obviously improved, the situation of abnormal welding quality can be reduced, and the consistency of batch welding quality can be ensured to be good.
