Description

Technical Field

[0001] The utility model belongs to the field of photovoltaic glass plate processing, and specifically relates to an EVA strip laying and welding integrated machine. 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 panels and complete the welding process. The working process is usually to transport the glass raw materials to the EVA strip laying and welding integrated machine, straighten the glass, and then load the EVA coil, and after punching and cutting pre-processing, the EVA strips are moved to the corresponding position of the glass raw materials. After the welding is completed, it enters the next process.

[0004] The existing EVA strip laying and welding equipment usually cuts and punches the EVA coil material after loading, and then moves it to the photovoltaic glass plate for welding. However, since the existing EVA strip laying and welding equipment usually does not have a position adjustment function when the EVA strip is moved, it is usually easy to cause the EVA strip to be misplaced when it is moved to the photovoltaic glass plate, and it cannot be accurately placed on the EVA strip, resulting in the EVA strip and the standard welding position of the photovoltaic glass plate being misplaced, resulting in welding not meeting the requirements. In view of this, the utility model provides an EVA strip laying and welding all-in-one machine. Utility Model Content
