Problems solved by technology

[0004] However, in the related art, the fixed frames of the above-mentioned photovoltaic modules mostly use aluminum rods to extrude long strips of aluminum profiles through dies, and then form them through anodic oxidation and other processes. However, the above-mentioned aluminum profiles are polluted during the processing process. It does not meet the national double-carbon requirements; on the other hand, the strength of the aluminum profile frame cannot meet the strength requirements of large-size photovoltaic modules; in addition, the processing technology of the aluminum frame is limited, especially in terms of cost. the needs of the book;

Embodiment 1

[0060] like Figure 2 to Figure 4 The fixed frame of the photovoltaic module shown is formed by roll forming of a steel plate. It should be pointed out that in the embodiment of the present invention, the steel plate is made of high-aluminum-zinc-aluminum-magnesium steel plate with anti-corrosion performance and no spraying. It can guarantee no perforation and corrosion for at least 20 years in the outdoor environment, which improves the service life of the frame and ensures the stability of the photovoltaic module. Specifically, such as figure 2 The frame shown in the figure includes a lower bottom plate 10, an outer plate 20, an upper top plate 30, a fixed portion 40, an inner plate 50 and an upper bottom plate 60. It should be noted here that the above-mentioned orientation description is only for the convenience of the description of the cross-sectional shape. Not a specific limitation on its orientation, where:

Embodiment 2

[0090] In the second embodiment of the present invention, a flexible glue film 70 is added, and other structures are the same as those in the first embodiment, and will not be repeated here; In the structure of the first embodiment, the silica gel needs to be applied into the U-shaped cavity 41 first. In order to ensure the adhesion between the glue and the U-shaped cavity 41 and the photovoltaic module, it is generally necessary to place more silica gel, resulting in waste of silica gel. ;

[0091] like Figure 10 As shown in the figure, the bottom of the U-shaped cavity 41 also has a flexible glue film 70, the flexible glue film 70 has glue holes, and there are gaps between the flexible glue film 70 and the two sides of the U-shaped cavity 41 to form glue injection aisle. It should be pointed out here that the flexible glue film 70 can be made of silicone material, and the holes are evenly distributed to meet the needs of glue dispensing; for example, Figure 11 As shown ...

The present invention relates to the technical field of photovoltaic module frame structures, in particular to a photovoltaic module fixing frame, a manufacturing method and a photovoltaic module assembling method. and the upper bottom plate, wherein the outer plate and the lower bottom plate are vertically arranged, the upper top plate is perpendicular to the outer plate and is arranged on the same side of the outer plate as the lower bottom plate; the fixed part is bent from the free end of the upper The U-shaped cavity is formed by bending twice; the inner plate, the inner plate is parallel to the outer plate, the inner plate and the lower plate, the outer plate and the fixed part form a fixed cavity; the upper plate is perpendicular to the inner plate, and the upper plate and the lower plate fit together, The free end of the upper base plate is fixedly connected with the free end of the lower base plate; the frame in the present invention adopts a double-folded structure with high strength, good ductility, good anti-corrosion and anti-cracking performance, and the strength can meet the requirements of high-power photovoltaic modules.

Description

technical field [0001] The present invention relates to the technical field of photovoltaic component frame structures, in particular to a photovoltaic component fixed frame, a manufacturing method and a photovoltaic component assembly method. Background technique [0002] Solar photovoltaic modules, also known as solar panels, are used to convert solar energy into electrical energy, or send them to batteries for storage, or drive loads to work. In practical applications, a frame is required to assemble the solar photovoltaic modules together. The stability of frame assembly is related to the normal operation of photovoltaic modules; [0003] In related technologies, such as figure 1 The aluminum profile photovoltaic module fixing frame shown in the figure includes a base plate 01, a support frame 02 perpendicular to one end of the base plate 01, and a buckle portion 03 arranged above the support frame 02. During the specific installation, the photovoltaic module 04 is clam...
