AI Technical Summary

Technical Problem

The existing photovoltaic sheet automatic anti-de-welding device is difficult to pull and tighten the bus bar during welding, resulting in loosening of the bus bar after welding, easy shaking of the junction box, and difficult to check the welding firmness, which increases the risk of false welding.

Method used

An automatic anti-welding device including lifting mounting, elastic pressing member, busbar expansion member and welding drive member is designed. The elastic pressing member and welding drive member are used to automatically tighten the busbar before welding, and pass through the spinous block and The bevel structure ensures that the bus bars fit closely with the terminals of the electrical box and checks the welding firmness through the elastic positioning and the edge-curling parts.

Benefits of technology

It improves welding quality, ensures the stability of the junction box, reduces the dummy welding rate, simplifies the welding process, improves the degree of automation, and facilitates the detection of welding firmness through the design of the edge-curling parts.

Abstract

The invention provides an automatic anti-falling welding device for photovoltaic pieces, and relates to the technical field of photovoltaic piece welding equipment. Comprising a lifting mounting piece, and an elastic pressing piece is mounted on the lifting mounting piece; a bus bar expansion piece is mounted on the elastic pressing piece; the bus bar expansion piece is used for extruding a photovoltaic piece bus bar to be attached to a positive terminal and a negative terminal of a photovoltaic piece junction box; two bus bar tightening pieces are mounted on the bus bar expansion piece; the two bus bar tightening pieces are used for rubbing and tensioning a photovoltaic sheet bus bar; a welding driving piece is mounted on the elastic pressing piece; according to the photovoltaic piece automatic anti-falling welding device, the bus bar can be automatically tightened during welding, the welding quality is improved, the bus bar is prevented from being bent and loosened, the stability of a junction box is improved, and the problems that an existing photovoltaic piece automatic anti-falling welding device cannot conveniently pull and tighten the bus bar during welding, and the junction box is prone to shaking due to the fact that the bus bar is loosened after being welded to the junction box are solved.
