[0002] The frame of solar photovoltaic modules is an important part of solar modules, mainly for supporting and fixing. The general service life of solar power generation system is about 25 years, so the best solar frame is made of sandblasted and oxidized aluminum profiles, which has relatively low cost, beautiful appearance, wear resistance and corrosion resistance, and the service life can reach more than 30-50 years.

[0003] Aluminum alloy frames often need to be drilled before assembly, and then connected to other parts by bolts. In the early days, when punching holes, workers usually held the profiles to fix them. Manual clamping was unstable and resulted in insufficient precision. There are also technical proposals to design molds that match the profiles for clamping, but there are many types of photovoltaic modules, which means there are also many types of profiles used as frames. Each profile requires a separate mold, which takes up storage space and increases the difficulty of production. Therefore, it is necessary to improve the fixture structure used for processing composite frame profiles of photovoltaic modules. Utility Model Content
