Description

Technical field

[0001] The utility model belongs to the technical field of photovoltaic component production, in particular to a secondary pressing device for photovoltaic components after framing. [Background Technology]

[0002] As an important innovation in the field of solar energy in recent years, full-screen solar panels are gradually attracting widespread attention. The principle of full-screen solar panels is that they use materials with high photoelectric conversion efficiency, which can convert more solar energy into electrical energy. At the same time, the full-screen design makes the surface of the component almost completely covered with photovoltaic materials, reducing the ineffective area and improving the overall power generation efficiency. Due to the full-screen design, the frame also needs to be changed accordingly. The old version frame 300 Figure 2 As shown, a C-shaped groove 301 is provided on the inner side. First, glue is applied in the C-shaped groove 301. After the glue is applied, the edge of the glass 400 is inserted into the C-shaped groove 301. The C-shaped groove 301 clamps the upper and lower surfaces of the glass to limit the position of the glass. The full-screen frame 200 is as shown in FIG. Figure 1 As shown, it includes a limiting side 201 for limiting the side of the component glass and a supporting plane 202 for supporting the edge of the lower surface of the component glass. The thickness of the limiting side 201 is very thin, so that the area of ​​the full screen is larger. After the glue is applied, the glass 400 is directly placed on the supporting plane 202 for framing. Since there is no limiting structure on the upper surface of the component glass, the component glass and the glue cannot be completely and tightly bonded, and the four corners or even the four sides of the component glass are warped, affecting the subsequent processing of the photovoltaic component and reducing productivity and product yield. Therefore, after the full-screen photovoltaic component is framed, it is necessary to design a secondary pressing equipment to press the component glass tightly on the frame.

[0003] In the prior art, Chinese patent publication number CN117558817A discloses a flattening device and a method for processing a conductive backplane. Although the scheme discloses a flattening device for flattening the conductive backplane, the flattening setting in the scheme mainly illustrates the structure of the supporting device and the downward pressure device, and cannot be directly used on a full-screen photovoltaic module production line.

[0004] Therefore, it is necessary to provide a secondary pressing device after photovoltaic module frame assembly to solve the above technical problems. [Utility Model Content]

At this time, the center of the glass is supported by the first support assembly 21, and the frame is supported by the second support assembly 22.

[0042] In this embodiment, the first support assembly 21 includes a support rod at the lower end and a support wheel provided at the upper end of the support rod and supporting the glass; the second support assembly 22 is provided as a pad.

[0043] In other embodiments, the structures of the first support assembly 21 and the second support assembly 22 can be designed as support rods or support plates according to actual conditions, which is not limited here.

[0044] The position limiting and correcting device 3 includes a first correcting mechanism 31 for limiting and correcting the two relatively short sides of the photovoltaic module and a second correcting mechanism 32 for limiting and correcting the two relatively long sides of the photovoltaic module.

At this time, the middle of the glass is supported on the first supporting assembly 21, and the frame is supported on the second supporting assembly 22. A plurality of first correcting mechanisms 31 limit and correct the two relatively short sides of the photovoltaic module, and a plurality of second correcting mechanisms 32 limit and correct the two relatively long sides of the photovoltaic module. A plurality of first correcting wheels 314 and a plurality of second correcting wheels 323 are all pressed against the frame to complete the correction of the four sides of the photovoltaic module; the second driving member 41 of the first pressing device 4 and the second pressing device 5 drives the first support plate 42 to descend, driving the clamping rod 43 to press on the edge of the glass 400. Figure 1As shown, the lower surface of the glass 400 is tightly adhered to the supporting plane 202 of the frame, and multiple first pressing devices 4 and multiple second pressing devices 5 are pressed downward at the same time, so that the four sides and four corners of the glass 400 are completely flattened and tightly adhered to the supporting plane 202 of the frame, completing the secondary pressing of the glass and the frame, making the glass and the frame completely and tightly bonded, solving the problem of the four corners or four sides of the glass warping after the full-screen frame is assembled; after the pressing is completed, the multiple first return wheels 314 and the multiple second return wheels 323 are all away from the frame, the first drive member 13 drives the conveyor line 11 to rise, and the photovoltaic components flow out, completing the secondary pressing action of the photovoltaic components.
