Technical Field
[0001] The utility model relates to a fixing jig, in particular to a jig for preventing CIGS component stacking from deflecting. Background Art
[0002] In the power electronics industry, such as semiconductors, photovoltaics, or thin films, the copper indium gallium selenide (CIGS) module is laminated using tempered glass, PVB film, CIGS chips, PVB film, and tempered glass. Because the PVB film will oxidize when in contact with air for a long time, resulting in a large number of bubbles during the lamination process, it needs to be placed in a vacuum environment within 24 hours after the lamination is completed and heated to melt the PVB film and adhere the tempered glass and chips.
[0003] Due to varying market demands, the size and thickness of CIGS modules are constantly changing. To adapt to the market and save equipment costs, and depending on the production process, some products, due to size and thickness issues, cannot be processed in-house. These products must be packaged and shipped to a suitable manufacturer for processing assistance. Therefore, when securing the CIGS module stack, a jig is necessary to prevent the stack from shifting. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a jig for preventing the deviation of CIGS component stacking, which can stably stack the glass stacking and achieve good position fixation, and can meet the fixation and stable transportation requirements of CIGS component stacking with different thicknesses.
[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is to provide a jig for preventing the stacking deviation of CIGS modules, comprising a plurality of jig bodies, each of which is a U-shaped structure composed of two L-shaped metal blocks. The inner and outer surfaces of the jig bodies are provided with high-temperature resistant Teflon tape, and the open ends of the jig bodies are installed with circular rings. The jig bodies are arranged in parallel in groups of two, and the circular rings on each group of parallel jig bodies are aligned with each other and connected by high-temperature resistant ropes.
[0006] In the jig for preventing CIGS component stacking from shifting, the two L-shaped metal blocks of each jig body are connected by adjusting screws to fix CIGS component stacks of different thicknesses.
[0007] In the above-mentioned jig for preventing CIGS component stacking deviation, the adjusting screw passes through the short side of one L-shaped metal block and is connected to the short side of another L-shaped metal block, and the circular ring is located in the middle of the long side of the L-shaped metal block.
[0008] In the jig for preventing stacking deviation of CIGS modules, the operating temperature of the high-temperature resistant Teflon tape and the high-temperature resistant rope is greater than or equal to 200°C.
[0009] The above-mentioned jig for preventing the CIGS component stack from shifting, wherein the glass stack includes a first tempered glass, a first PVB film, a CIGS chip, a second PVB film and a second tempered glass stacked in sequence.
[0010] In the jig for preventing CIGS component stacking deviation, the first tempered glass, the first PVB film, the CIGS chip, the second PVB film and the second tempered glass are aligned with each other.
[0011] The jig for preventing the CIGS component stack from shifting is provided above, wherein the number of the jig bodies is four and they are distributed at the four corners around the CIGS component stack.
[0012] Compared to existing technologies, this new invention offers the following advantages: The jig for preventing CIGS module stacking from shifting features a U-shaped body, arranged in pairs and connected by ropes. This effectively secures both sides of the CIGS stack, ensuring stable positioning during transport and meeting the requirements for securing CIGS modules of varying thicknesses. The U-shaped jig also features screw-loaded pressure for adjustable clearance, ensuring better securing of both sides of the CIGS stack, with a stacking error within 1mm.
