Description

Technical Field

[0001] This utility model relates to the field of photovoltaic film application technology, specifically a film application device for photovoltaic encapsulation film. Background Technology

[0002] In the current booming development of the photovoltaic industry, photovoltaic encapsulation film is a key material for protecting photovoltaic panels and improving photoelectric conversion efficiency. The quality of its application directly affects the performance and service life of photovoltaic products. However, existing photovoltaic encapsulation film application devices have some shortcomings.

[0003] Traditional coating equipment has a single function and lacks integrated dust removal and exhaust design. The surface of the photovoltaic panel needs to be cleaned before the film is applied, and the air is vented by operating a scraper after the film is applied. This may result in defects such as air bubbles and foreign objects between the film and the photovoltaic panel during the coating process. It also increases the production steps, affects the production efficiency of the encapsulation film, and increases the production cost. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a film-applying device for photovoltaic encapsulation films, which solves the problems of conventional film-applying devices having limited functionality, lacking simultaneous dust removal and exhaust, and increasing production steps and costs.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A photovoltaic encapsulation film application device includes: a positioning device, wherein a film coating device is slidably connected to the outer wall of the bottom of the positioning device; the positioning device includes a base, wherein a positioning groove is formed on the outer wall of the top of the base, a sliding hole is formed on the inner wall of the bottom of the positioning groove, a placement plate is slidably connected to the inner wall of the positioning groove, a sliding column and a compression spring are fixedly connected to the outer wall of the bottom of the placement plate, a fixing groove is symmetrically formed on the outer wall of the side of the placement plate, a clamping groove is symmetrically formed on the outer wall of the top of the base, a sliding rod is symmetrically fixedly connected to the inner wall of the clamping groove, a pull plate is slidably connected to the outer wall of the sliding rod, a pressure spring is symmetrically fixedly connected to the outer wall of the pull plate, a clamping block is fixedly connected to the outer wall of the pull plate on the side away from the pressure spring, and a sliding groove is symmetrically formed on the outer wall of the side of the base.

[0009] Preferably, the inner wall of the sliding hole is slidably connected to the outer wall of the sliding column, and the outer wall of the compression spring on the side away from the placement plate is fixedly connected to the inner wall of the bottom of the positioning groove. When the placement plate is pressed, the placement plate is compressed downward by gravity, causing the placement plate to descend.

[0010] Preferably, the outer wall of the pull plate is slidably connected to the inner wall of the clamping groove, and the outer wall of the pressure spring on the side away from the pull plate is fixedly connected to the inner wall of the clamping groove. When the pull plate is pulled, the pressure spring is compressed, and the pull plate will drive the clamping block to move.

[0011] Preferably, the sliding columns are arranged in an array along the outer wall of the bottom of the placement plate, and the inner wall of the fixing groove is slidably connected to the outer wall of the clamping block. During the descent of the placement plate, it will contact the clamping block. Since the upper surface of the clamping block is inclined, it will squeeze the clamping block and drive the pull plate to move outward along the clamping groove through the sliding rod. When the placement plate descends to the fixing groove and corresponds to the clamping block, under the elastic force of the pressure spring, the clamping block slides into the fixing groove, thereby fixing the placement plate in the positioning groove.

[0012] Preferably, the coating device includes a sliding frame, a lifting plate is slidably connected to the inner wall of the side of the sliding frame, a lifting threaded rod is rotatably connected to the outer wall of the top of the lifting plate, and a coating roller, a brush and a scraper are fixedly connected to the outer wall of the bottom of the lifting plate.

[0013] Preferably, the coating roller is positioned between the brush and the scraper, the outer wall of the lifting threaded rod is threadedly connected to the inner wall of the top of the sliding frame, and the outer wall of the bottom of the sliding frame is slidably connected to the inner wall of the slide groove. During the movement of the sliding frame, the brush first cleans the dust and impurities on the photovoltaic panel to avoid affecting the coating quality. Then, the coating roller applies the new adhesive film to the photovoltaic encapsulation film. Subsequently, the scraper removes the air from the surface of the photovoltaic panel, allowing the adhesive film to better adhere to the photovoltaic encapsulation film.

[0014] (III) Beneficial Effects

[0015] This invention provides a device for applying photovoltaic encapsulating film. It has the following advantages:

[0016] (i) The positioning device, through the cooperation of the placement plate, compression spring, clamping block and fixing groove, automatically presses down and triggers the clamping block to engage when the photovoltaic panel is placed, so as to stably fix the photovoltaic panel in the positioning groove and avoid the film from shifting due to the movement of the photovoltaic panel during the lamination process. Conversely, when the pull plate is pulled, the pressure spring is compressed, and the pull plate drives the clamping block to move and be pulled out of the fixing groove. At this time, the placement plate is unrestricted. The compression spring pushes the placement plate to slide upward along the sliding hole through the sliding column, pushing the photovoltaic panel out, which facilitates the quick replacement of the photovoltaic panel and the next lamination operation.

[0017] (ii) The coating device uses a brush, a coating roller, and a scraper. During the movement of the sliding frame, the brush first removes dust and impurities from the surface of the photovoltaic panel, eliminating bonding defects caused by foreign objects. After the coating roller applies the adhesive film, the scraper promptly removes air, ensuring that the adhesive film and the photovoltaic panel are tightly bonded without air bubbles. This achieves a one-stop operation from cleaning to coating, effectively improving the protective performance and service life of the encapsulation film. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a photovoltaic encapsulation film application device, comprising: a positioning device 1, with a film application device 2 slidably connected to the outer wall of the bottom of the positioning device 1; the positioning device 1 includes a base 11, a positioning groove 12 is formed on the outer wall of the top of the base 11, a sliding hole 13 is formed on the inner wall of the bottom of the positioning groove 12, a placement plate 14 is slidably connected to the inner wall of the positioning groove 12, a sliding column 15 and a compression spring 16 are fixedly connected to the outer wall of the bottom of the placement plate 14, a fixing groove 17 is symmetrically formed on the outer wall of the side of the placement plate 14, a clamping groove 18 is symmetrically formed on the outer wall of the top of the base 11, a sliding rod 19 is symmetrically fixedly connected to the inner wall of the clamping groove 18, a pull plate 191 is slidably connected to the outer wall of the sliding rod 19, a pressure spring 192 is symmetrically fixedly connected to the outer wall of the pull plate 191 on the side away from the pressure spring 192, a clamping block 193 is fixedly connected to the outer wall of the pull plate 191 on the side away from the pressure spring 192, and a sliding groove 194 is symmetrically formed on the outer wall of the side of the base 11.

[0026] The inner wall of the sliding hole 13 is slidably connected to the outer wall of the sliding column 15. The outer wall of the compression spring 16 on the side away from the placement plate 14 is fixedly connected to the inner wall of the bottom of the positioning groove 12. When the placement plate 14 is pressed, the placement plate 14 is compressed downward by gravity, causing the placement plate 14 to descend.

[0027] The outer wall of the pull plate 191 is slidably connected to the inner wall of the clamping groove 18, and the outer wall of the pressure spring 192 on the side away from the pull plate 191 is fixedly connected to the inner wall of the clamping groove 18. When the pull plate 191 is pulled, the pressure spring 192 is compressed, and the pull plate 191 will drive the clamping block 193 to move.

[0028] The sliding columns 15 are arranged in an array along the outer wall of the bottom of the placement plate 14. The inner wall of the fixing groove 17 is slidably connected to the outer wall of the clamping block 193. During the descent of the placement plate 14, it will contact the clamping block 193. Since the upper surface of the clamping block 193 is inclined, it will squeeze the clamping block 193 and drive the pull plate 191 to move outward along the clamping groove 18 through the sliding rod 19. When the placement plate 14 descends to the fixing groove 17 and corresponds to the clamping block 193, under the elastic force of the pressure spring 192, the clamping block 193 slides into the fixing groove 17, thereby fixing the placement plate 14 in the positioning groove 12.

[0029] The film coating device 2 includes a sliding frame 21, a lifting plate 22 is slidably connected to the inner wall of the side of the sliding frame 21, a lifting threaded rod 23 is rotatably connected to the outer wall of the top of the lifting plate 22, and a film coating roller 24, a brush 25 and a film scraper 26 are fixedly connected to the outer wall of the bottom of the lifting plate 22.

[0030] The coating roller 24 is positioned between the brush 25 and the scraper 26. The outer wall of the lifting threaded rod 23 is threadedly connected to the inner wall of the top of the sliding frame 21, and the outer wall of the bottom of the sliding frame 21 is slidably connected to the inner wall of the slide groove 194. During the movement of the sliding frame 21, the brush 25 first cleans the dust and impurities on the photovoltaic panel to avoid affecting the coating quality. Then, the coating roller 24 applies the new adhesive film to the photovoltaic encapsulation film. Subsequently, the scraper 26 removes the air from the surface of the photovoltaic panel, allowing the adhesive film to better adhere to the photovoltaic encapsulation film.

[0031] When in use, the photovoltaic panel is placed on the positioning device 1. The positioning device 1 is used to position and fix the photovoltaic panel to prevent the photovoltaic panel from moving during the coating process, which would cause inaccurate coating. Then, the coating device 2, which is slidably connected to the positioning device 1, is used to coat the photovoltaic panel.

[0032] First, the photovoltaic panel is placed on the placement plate 14. After the film is placed, the placement plate 14 is pressed down. The placement plate 14 is compressed downward by gravity, which compresses the compression spring 16, causing the placement plate 14 to descend. During the descent, it will come into contact with the clamping block 193. Since the upper surface of the clamping block 193 is inclined, it will squeeze the clamping block 193 and drive the pull plate 191 to move outward along the clamping groove 18 through the slide rod 19. When the placement plate 14 descends to the fixing groove 17 and corresponds to the clamping block 193, under the elastic force of the pressure spring 192, the clamping block 193 slides into the fixing groove 17, thereby fixing the placement plate 14 in the positioning groove 12. At the same time, the photovoltaic panel also slides into the positioning groove 12 to prevent displacement during the film coating process.

[0033] After the photovoltaic panel is fixed, by rotating the lifting threaded rod 23, the lifting plate 22 can slide up and down on the inner side wall of the sliding frame 21 due to the action of the thread. The height of the lifting plate 22 can be adjusted according to the actual needs of film application. When the lifting plate 22 descends to the appropriate position, it pushes the sliding frame 21. The outer wall of the bottom of the sliding frame 21 slides and connects with the inner wall of the sliding groove 194 on the base 11, so that the film coating roller 24 contacts the surface of the photovoltaic panel. During the movement of the sliding frame 21, the brush 25 will first clean the dust and impurities on the photovoltaic panel to avoid affecting the film coating quality. Then the film coating roller 24 applies the new adhesive film to the photovoltaic encapsulation adhesive film. Subsequently, the scraper plate 26 removes the air from the surface of the photovoltaic panel, so that the adhesive film and the photovoltaic encapsulation adhesive film can better adhere to each other, ensuring the adhesion quality of the adhesive film and completing the film coating operation.

[0034] After the film coating is completed, pull the pull plate 191 again, the pressure spring 192 is compressed, and the pull plate 191 drives the clamping block 193 to move and be pulled out of the fixing groove 17. At this time, the placement plate 14 is unrestricted. The compression spring 16 pushes the placement plate 14 to slide upward along the sliding hole 13 through the sliding column 15, pushing the photovoltaic panel out, which is convenient for quickly replacing the photovoltaic panel and carrying out the next film coating operation.
