Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a tool for cleaning excess adhesive from photovoltaic modules. Background Technology

[0002] Photovoltaic modules consist of glass, EVA, solar cells, backsheet, and frame. During the production process, solar cells are sandwiched between glass and backsheet using EVA to form a laminate, and then the frame is assembled onto the edge of the laminate to form a photovoltaic module.

[0003] Silicone sealant is needed between the laminate and the frame. The sealant is filled into the mounting groove of the frame, and the overflow of the sealant is controlled to ensure the laminate's sealing and insulation. Overflow refers to the even overflow of sealant at the joint between the laminate and the frame; there should be no insufficient sealant, air bubbles, or curled edges. Sufficient sealant ensures insulation but can easily cause cosmetic defects, requiring repair and cleaning.

[0004] In the prior art, the utility model patent with publication number CN211605174U is a photovoltaic module overflow cleaning tool; the utility model patent with publication number CN221311608U is a silicone edge cleaning component; both are used for cleaning overflow, but the above-mentioned prior art has a sharp blade, which can easily damage the surface of the laminate and the frame, and can easily remove too much sealant between the laminate and the frame.

[0028] The present invention will be further described in detail below with reference to the embodiments.

[0029] Specific embodiments of the photovoltaic module adhesive cleaning tool provided by this utility model:

[0030] Please see Figure 1-6 A photovoltaic module adhesive overflow cleaning tool, including a scraper 1 and a drive rod 2 connected to the scraper 1.

[0031] The shovel 1 includes a middle part 101 and two bent parts 102 integrally connected to both sides of the middle part 101. The two bent parts 102 bend toward the middle part 101 on the same side and are perpendicular to each other. The shovel 1 is formed by bending the two edges of a flat plate toward the same side of the flat plate. The two edges are the two bent parts 102, and the middle part 101 is between the two edges. The middle part 101 and the two bent parts 102 form an obtuse angle of 135 degrees, that is, the relationship between the two bent parts 102 is perpendicular.

[0032] Both ends of the scraper 1 are provided with cutting edges 104, which are formed by chamfering at the ends of the scraper 1. The cutting edges 104 correspond to the ends of the middle part 101 and the two bent parts 102. When the scraper 1 is pushed and pulled by the drive rod 2, the cutting edges 104 at both ends of the scraper 1 can clean up the excess glue respectively; the double cutting edge 104 structure enables this cleaning tool to have two methods of cleaning excess glue, pushing and pulling.

[0033] During cleaning, the cutting edges 104 at the ends of the two bent portions 102 are respectively attached to the surface of the frame and the laminate, and the cutting edge 104 at the end of the middle portion 101 corresponds to the sealant on the outside of the gap between the frame and the laminate. In this way, the bent portions 102 completely clean the excess sealant from the surface of the frame and the laminate. The middle portion 101 leaves a neat portion of the sealant at the gap between the frame and the laminate, avoiding excessive removal of the sealant at the gap. This ensures a neat appearance without affecting the sealing performance of the sealant.

[0034] The connection between the two bends 102 and the middle part 101 is provided with a first rounded corner 103 to prevent the outer edge of the cutting edge 104 at the connection between the bend 102 and the middle part 101 from forming a sharp edge; the corner of the bend 102 away from the middle part 101 is provided with a second rounded corner 105 to prevent the cutting edge 104 from forming a sharp edge at the outer corner of the bend 102; the cleaning tool has no sharp edge, only straight and rounded edges, so it is not easy to damage the laminate and frame surface during operation, thus protecting the photovoltaic module.

[0035] The drive rod 2 includes a rod body 201, a handle 202, and two connecting rods 203. The first end of the rod body 201 is connected to the middle edge of two bends 102 respectively through the two connecting rods 203. The middle edge of the bends 102 is connected to a connecting block 106 that is connected to the drive rod 2, i.e., the connecting rod 203. There are two connecting blocks 106, which are connected to the two bends 102 respectively. The two connecting blocks 106 are connected to the two connecting rods 203 respectively. In this embodiment, both the connecting rods 203 and the connecting blocks 106 are steel structures, and the connection method between the connecting rods 203 and the connecting blocks 106 is welding.

[0036] The first end of the rod 201 is bent to form a curved portion 2011. An arc-shaped reinforcing rod 204 is connected to the inner side of the curved portion 2011. The reinforcing rod 204 plays a reinforcing role and can reduce the deformation of the curved portion 2011. In this embodiment, the rod 201 with the curved portion 2011 allows the driving rod 2 to have a better cutting angle on the cutting edge 104 when pushing and pulling the scraper 1 to scrape glue, which can clean up the overflow glue in both pushing and pulling states, making the operation comfortable and convenient.

[0037] The second end of the rod 201 is provided with a handle 202; the handle 202 can be made of wood, hard plastic or steel; the handle 202 is T-shaped, and the T-shaped handle 202 is convenient to push and pull when holding, which facilitates the separate scraping of glue by the double-ended blades 104.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
