Description

Technical Field

[0001] The utility model relates to the technical field of glue spraying mechanical equipment, in particular to the structure of a photovoltaic double-glass edge sealing glue die head. Background Art

[0002] The edge sealant die is a device that uses a glue dispenser and mechanical movement to extrude the sol and apply glue in a straight line. The edge sealant die is a special device used for waterproofing and moisture-proofing of photovoltaic modules after edge trimming. The manufacturing of solar panels is complex and challenging for many reasons, one of which is how to seal solar panels to withstand weather factors in exposed environments. When panels are exposed to weather, the edge sealing process affects the quality of the panel.

[0003] Simply put, moisture is the enemy of solar panels. Moisture entering the panel can lead to poor performance and premature failure, so it is critical to properly seal the panel to prevent moisture. When engineers evaluate manufacturing quality and efficiency, the edge sealing process remains a top priority because it can have a very large impact on the final product. As demand for solar energy grows, the benefits of improved edge sealing processes will spread throughout the photovoltaic industry in the future. Traditionally, edge sealing is accomplished by using tape to seal the components together. Tape sealing can be done manually or automatically. Although tape has long been the preferred sealing method, it is applied manually or using automated equipment. However, time inefficiencies, material waste, and lack of dimensional flexibility have led the industry to seek new, more versatile solutions. Time inefficiency: Downtime caused by changing tape rolls. Edge sealing tape is supplied in reels that are mounted on the tape dispensing head. These reels need to be changed frequently during the production process, which causes machine downtime and also requires manpower to change them. Reel change operations introduce costly production interruptions to otherwise lean production lines.

[0004] Material waste: Sealant overlap at joints; To ensure full coverage of the edge seal tape around the perimeter of the solar panel, the edge seal tape is often overlapped at corners and start / stops. This overlap results in excess extrusion of the edge seal tape. The excess tape needs to be manually trimmed from the panel, which ultimately results in waste. This extra step results in a double waste of time and material.

[0005] Panel sizes vary: Fixed tape size; edge sealing tape has fixed width and thickness. Existing methods lack flexibility to quickly adjust tape size and thickness, which leads to inefficiencies in the manufacturing process if products require different sizes of edge sealing tape.

[0006] The solar industry has long reached a consensus on the hazards and impacts of water vapor intrusion on components. It not only causes corrosion to battery chips, TCO film layers, electrical connectors, etc., resulting in loss of battery function, but also causes a significant decline in component performance. The encapsulation film, especially the EVA film, will decompose and produce acetic acid after contacting water vapor, which lowers the pH value and increases the surface corrosion rate of the batteries and solder strips in the component. Although EVA produces acetic acid relatively slowly, the entire process does not require too much catalytic reaction to cause yellowing of the component appearance and deterioration of performance.

[0007] Therefore, it is necessary to design a structure of a photovoltaic double-glass edge sealant die head to solve the problems of low efficiency, high cost, poor effect and material waste of existing photovoltaic solar panel edge sealing tapes. Utility Model Content
