Description
Technical Field
[0001] This utility model belongs to the field of photovoltaic technology, specifically an EVA film pasting device with a positioning structure. Background Technology
[0002] In fields such as photovoltaic modules and electronic component packaging, EVA film bonding is a critical process, and its bonding accuracy directly affects product quality and performance. Currently available EVA film bonding devices generally suffer from inaccurate positioning, easily leading to film misalignment and wrinkles. This not only reduces product yield but also increases production costs and wastes raw materials. Furthermore, traditional devices have low automation levels, rely on manual operation, resulting in low production efficiency, and the instability of manual operation further exacerbates positioning errors. This innovative design of an EVA film bonding device with a positioning structure aims to solve these pain points. Through a precise positioning structure design combined with an automated control system, it achieves high-precision and high-efficiency EVA film bonding, improving product yield, reducing production costs, meeting the industry's demand for high-quality, high-capacity production, and promoting technological progress and industrial upgrading in related fields.
[0003] Meanwhile, a method for positioning and fixing a film on glass is disclosed (announcement number CN117621477A). The equipment used includes a glass conveying device, a film coating device, and a positioning and fixing device. The positioning and fixing device is located above the second work station and includes a film position detection mechanism, a film position adjustment mechanism, and a film position fixing mechanism. The film position adjustment mechanism includes four suction cups, which are respectively located above the four corners of the film.
[0004] The above-described method for positioning and fixing films on glass is problematic because the EVA film is soft and thin. Even with four suction cups holding the four corners of the film, unevenness may still occur during position adjustment. Improper suction control or interference from external factors during adjustment can also lead to air bubbles and wrinkles in the EVA film.
[0005] Therefore, an EVA film bonding device with a positioning structure is proposed to address the above problems. Utility Model Content
[0006] To address the problems mentioned in the background art, this utility model provides an EVA film pasting device with a positioning structure, which has the advantages of positioning the pasted film and being applicable to films of different widths.

[0018] Preferably, a second placement roller is fixedly provided on the front end face of the support plate, and a limiting post is fixedly provided on the front end face of the support plate.
[0019] By adopting the above technical solution, the placement of roller two and limiting post plays a guiding and limiting role for the EVA film, ensuring that the film maintains the correct direction and position during the conveying process, avoiding film deviation or wrinkles, and improving the flatness and quality of bonding.
[0020] Preferably, a hydraulic telescopic column is fixedly provided on the front end face of the support plate, a hydraulic telescopic rod is fixedly provided on the front end face of the hydraulic telescopic column, and a pressure plate is fixedly provided on the front end face of the hydraulic telescopic rod.

[0030] 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.
[0031] The following describes an embodiment of this utility model based on its overall structure.
[0032] like Figures 1 to 4 As shown, this utility model provides an EVA film pasting device with a positioning structure, including an electric slide rail 2 10, a slider 2 11 slidably disposed inside the electric slide rail 2 10, a telescopic rod 12 fixedly disposed on the front end face of the slider 2 11, an electric rotating shaft 13 fixedly disposed on the front end face of the telescopic rod 12, and a winding roller 14 fixedly disposed on the front end face of the electric rotating shaft 13. The winding roller 14 can be rotated through the electric rotating shaft 13, and the angle of the winding roller 14 can be flexibly adjusted according to the pasting requirements to better fit pasting surfaces of different shapes or angles, thereby improving the accuracy and quality of pasting.
[0033] In this embodiment, the lower end face of the electric slide rail 2 10 is fixedly provided with a slider 9, the outer side of the slider 9 is fixedly provided with a limiting plate 2, and the inner side of the limiting plate 2 is fixedly provided with an electric slide rail 3. The electric slide rail 3 and the slider 9 are slidably arranged. The limiting plate 2 plays a limiting role in the slider 9, preventing the slider 9 from disengaging from the electric slide rail 3 during the sliding process, thus ensuring the stability and safety of the device operation.
[0034] The lower end face of the limiting plate 2 is fixedly provided with a placement platform 1. The interior of the placement platform 1 is provided with a sliding groove 4. The placement platform 1 provides a stable support base for the entire device, making the device more stable during operation and reducing the impact of shaking and vibration on the bonding effect.
[0035] A rotating shaft 8 is fixedly installed inside the slide 4, and a threaded rod 7 is fixedly installed on the front end face of the rotating shaft 8. The moving distance of the component can be precisely controlled through the threaded rod 7, which helps to perform positioning and pasting operations more accurately.
[0036] A handle 5 is fixedly provided on the front end face of the threaded rod 7, and an anti-slip strip 6 is fixedly provided on the outer side of the handle 5. The handle 5 allows the operator to manually rotate the threaded rod 7, making the operation easier and more direct.
[0037] A support plate 15 is fixedly provided on the upper end face of the placement platform 1, and a placement roller 16 is fixedly provided on the front end face of the support plate 15. The placement roller 16 can be used to place EVA film rolls, which facilitates the storage and retrieval of the film and enables the film to be supplied in an orderly manner during the pasting process.
[0038] The front end face of the support plate 15 is fixedly provided with a second placement roller 17 and a limiting post 18. The second placement roller 17 and the limiting post 18 play a guiding and limiting role for the EVA film, ensuring that the film maintains the correct direction and position during the conveying process, avoiding the film from shifting or wrinkling, and improving the flatness and quality of the pasting.
[0039] A hydraulic telescopic column 19 is fixedly provided on the front end face of the support plate 15, a hydraulic telescopic rod 20 is fixedly provided on the front end face of the hydraulic telescopic column 19, and a pressure plate 21 is fixedly provided on the front end face of the hydraulic telescopic rod 20. Through the hydraulic telescopic column 19, the hydraulic telescopic rod 20, and the pressure plate 21, the pressure of the pressure plate 21 can be controlled by the hydraulic system. During the EVA film pasting process, appropriate pressure can be applied to the film so that the film can better adhere to the pasting surface and ensure a firm bond. At the same time, the pressure can be adjusted according to different pasting requirements.
[0040] Working principle and process of an EVA film bonding device with a positioning structure:
[0041] Place the item to be coated with EVA film on the placement platform 1. The placement platform 1 provides a stable supporting surface for the item, ensuring smooth subsequent coating. Place the EVA film on placement rollers 16 and 17. Placement rollers 16 and 17 support and guide the film, allowing it to unfold orderly for easy coating. Simultaneously, the limiting post 18 restricts the position of the film, preventing it from shifting during unfolding. Rotate the handle 5. Since the outer side of the handle 5 is fixed with anti-slip strips 6, these strips increase the friction between the hand and the handle 5, making it easier for the operator to rotate the handle 5. The rotation of the handle 5 drives the threaded rod 7 to rotate. The threaded rod 7 is connected to the rotating shaft 8 fixed inside the slide groove 4, thus achieving stable rotation of the threaded rod 7. As the threaded rod 7 rotates, the components that cooperate with it will move within the slide groove 4, thereby driving the entire limiting plate 2 and the electric slide rail 10 installed on the limiting plate 2 to adjust their lateral position to accommodate items of different sizes and adhesive requirements. The electric slide rail 3 is activated, and the slider 9 slides within the electric slide rail 3. The slider 9 is fixed on the limiting plate 2, so the sliding of the slider 9 will drive the limiting plate 2 and the connected electric slide rail 10 to adjust their longitudinal position, further... To accurately determine the pasting position, the telescopic rod 12 extends and retracts, adjusting the height of the winding roller 14 to match the surface height of the item to be pasted. The electric shaft 13 starts, rotating the winding roller 14 and adjusting its angle to better conform to the surface shape of the item, ensuring accurate adhesion of the adhesive film. The electric slide rail 2 10 starts, and the slider 2 11 slides within it. The movement of the slider 2 11 moves the telescopic rod 12, the electric shaft 13, and the winding roller 14 together. During this movement, the winding roller 14 gradually unfolds the EVA adhesive film, covering the surface of the item to be pasted. When the telescopic column 19 is activated, it drives the hydraulic telescopic rod 20 to extend and retract. The pressure plate 21 fixed at the front end of the hydraulic telescopic rod 20 moves downward, pressing the unfolded EVA film firmly onto the surface of the item, ensuring a tight fit between the film and the surface, thus improving the quality and strength of the adhesion. After the adhesion is completed, the components are reset in reverse order. The hydraulic telescopic column 19 drives the pressure plate 21 to rise back to its initial position; the electric slide rail 10, telescopic rod 12, electric rotating shaft 13, and other components return to their initial state, preparing for the next adhesion operation. The item with the EVA film adhered is then removed from the placement platform 1, completing the entire adhesion process.
