Description

Technical Field

[0001] This utility model belongs to the field of back glass threading auxiliary technology, specifically relating to a back glass threading auxiliary component for double-glass photovoltaic modules. Background Technology

[0002] The photovoltaic industry is an industry that converts light energy into electrical energy. As an important part of the world's renewable energy market, solar power generation systems are a key link in the industry. The core component of solar photovoltaic modules is the solar power generation system. Its principles and technologies directly determine the energy conversion efficiency and lifespan of the entire system.

[0003] Solar photovoltaic modules can be divided into single-glass modules and double-glass modules based on their encapsulation materials. Single-glass modules consist of photovoltaic glass, encapsulating film, solar cells, and an organic backsheet. The backsheet, located on the back of the solar panel, provides mechanical support for the cells. However, organic polymer materials are prone to aging, and their ability to prevent moisture penetration weakens over time, leading to quality issues such as PID (Potential Ingress) and snail trails in the solar panel. In contrast, double-glass modules employ a symmetrical structure of two tempered glass surfaces, offering superior mechanical properties. Furthermore, glass, as an inorganic material, is less susceptible to aging and deformation caused by temperature and humidity factors. Therefore, double-glass modules exhibit stronger weather resistance and PID resistance than single-glass modules, resulting in a significantly longer lifespan. They are now widely used in distributed photovoltaic power station systems.

[0004] Double-glass photovoltaic (PV) modules typically require the busbars connecting the solar cell strings to be welded to the PV junction box to conduct the current generated by the solar cells inside the module. During the stacking process of double-glass PV modules with integrated junction boxes, production workers often have to manually adjust the position of the busbar leads multiple times before they can smoothly pass through the back glass opening, resulting in low production efficiency. Furthermore, these repeated adjustments can easily lead to defects such as microcracks, fragmentation, and misalignment in the solar cell strings, thus keeping factory costs high.

[0009] In order to ensure both the fixation of the lead wire and the removal of the panel after the glass is assembled, the rectangular part of the positioning groove is further designed to have a transition fit with the lead wire.

[0010] In order to allow the plate to arch to a certain height and ensure the fixation effect on the lead wire, support plates are integrally formed on both sides of the plate, and there is an angle between the support plates and the plate.

[0011] To reduce costs, minimize friction, and effectively support and fix the lead wires, the board body is made of PET material.

[0012] To minimize the risk of friction with components, chamfers are further provided at the corners of the support plate and extension plate.

[0013] To enable rapid positioning of the plate and improve work efficiency, the back of the extension plate is further provided with several protrusions, the sides of which are flush with the sides of the plate.

[0037] By adopting the above technical solution, the risk of friction with components can be avoided to the greatest extent.

[0038] Example 2
