Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic glass plate processing, and specifically relates to a photovoltaic glass plate correction welding mechanism. Background Art

[0002] Photovoltaic glass, as an important component of photovoltaic modules, is mainly used to encapsulate and protect solar panels. Its core properties include high light transmittance, high strength and strong corrosion resistance. Ultra-white glass has become the preferred material for manufacturing photovoltaic glass due to its excellent light transmittance. According to different manufacturing processes and application scenarios, photovoltaic glass can be divided into ultra-white rolled glass and ultra-white float glass, among which ultra-white rolled glass occupies a dominant position in the market.

[0003] During the preparation process of photovoltaic glass, it is necessary to lay EVA strips on the photovoltaic glass plate and complete the welding process. The working process is usually that after the glass raw materials are transported to the EVA strip laying and welding integrated machine, the EVA strip laying and welding integrated machine will straighten the glass, and then the EVA coil will be loaded through the loading roller of the EVA strip laying and welding integrated machine, and the EVA strips will be formed into EVA strips after shearing and punching by the shearing mechanism and punching mechanism and stored on the strip carrier. The strips will be transplanted to the corresponding position of the glass raw materials by a transplanting robot and finally fixed by welding. After completing the above processes, the glass plate will be transported to the next sub-process.

[0004] The existing EVA strip laying and welding integrated machine is used to straighten and weld the photovoltaic glass panel. Usually, after the straightening mechanism is used to straighten the glass, after the EVA strip is laid on the photovoltaic glass panel, it is usually manually spot welded to weld the EVA strip and the photovoltaic glass panel together. The efficiency of manual electric welding is low. There are also equipment on the market that uses automation for welding, but it still moves to other processes to weld with the EVA strip after the photovoltaic glass panel is straightened. Two processes are required to complete, and the straightening and welding are not orderly combined, resulting in a long process time and low efficiency. In view of this, the present invention provides a photovoltaic glass panel straightening welding mechanism. Utility Model Content
