Description

Technical Field

[0001] This utility model relates to the field of solar panel technology, and in particular to a device for bonding a protective film to the surface of a solar panel. Background Technology

[0002] During the production and transportation of solar panels, a protective film needs to be applied to their surface to prevent scratches and contamination. Traditional manual film application suffers from low efficiency, inaccurate alignment, and the formation of bubbles and wrinkles, affecting the protective effect and product appearance. Existing semi-automatic film application equipment often suffers from drawbacks such as cumbersome material loading and positioning, uneven film traction, and poor pressing effect. Therefore, a protective film application device for solar panels is proposed. Utility Model Content

[0003] To address at least one of the aforementioned technical shortcomings, this utility model provides a solar panel surface protective film bonding device, comprising: a worktable, the upper surface of which is provided with a positioning groove for positioning a feeding component, the feeding component being slidably pulled out inside the positioning groove for quick manual feeding, the feeding component including a solar panel frame for fitting the bottom of the solar panel, the end of the solar panel frame being provided with a handle, the worktable being provided with a film-releasing component for releasing the protective film, a film-pulling component for pulling the protective film to cover the surface of the solar panel, a roller pressing component located directly above the positioning groove for pressing the protective film, and a cutting component for cutting the protective film.

[0004] Furthermore, the film-laying assembly includes a film-laying motor, a timing belt assembly, and a film-laying roller. A protective film is installed on the film-laying roller, and the output end of the film-laying motor drives the film-laying roller to rotate through the timing belt assembly to lay the film.

[0005] Furthermore, the film-pulling assembly includes an electric lead screw fixed to the worktable. A connecting frame is provided on the moving end of the electric lead screw. A clamping cylinder located above the positioning groove is fixedly connected to the connecting frame. A clamping plate that presses against the protective film is provided at the output end of the clamping cylinder. A support frame with a U-shaped structure is fixedly connected to the worktable. Slide rails are fixedly connected to the inner surfaces of both sides of the support frame that are parallel to the positioning groove. Slider blocks are slidably connected to the slide rails. The sliders are fixedly connected to the connecting frame. Clamping cylinders are fixedly connected to the sliders. The clamping ends of the clamping cylinders clamp the two sides of the protective film respectively. A limit switch is provided on the support frame at the extreme position of the slider.

[0006] Furthermore, the rolling assembly includes two gantry frames for support, with at least one electric lead screw and a slide bar between the two gantry frames. A rolling cylinder is fixedly connected to the moving end of the electric lead screw, and a roller shaft is rotatably connected to the output end of the rolling cylinder. A limit switch is fixedly connected to the gantry frame at the extreme position of the moving end of the electric lead screw.

[0007] Furthermore, the cutting assembly includes a cutting cylinder fixedly connected to a gantry frame near the film-laying assembly, and a cutting blade is fixedly connected to the output end of the cutting cylinder.

[0008] Furthermore, the cutting edge of the cutting tool is set with a sharp angle in the middle.

[0009] Furthermore, the surface of the roller is covered with an elastic rubber layer to increase the contact friction with the protective film and to prevent damage to the surface of the protective film during the pressing process. Beneficial effects

[0010] The workbench surface is precisely machined with a positioning groove that matches the shape of the feeding assembly. Operators can hold the handle and push the feeding assembly, carrying the solar panel to be laminated, into the working position like a drawer along the positioning groove, ensuring accurate positioning each time. The protective film roll is installed on the film-laying assembly. During lamination, the film-pulling assembly moves first, pulling the film from the film-laying assembly and laying it flat on the solar panel surface above the positioning groove; then, the roller assembly descends, pressing the protective film tightly onto the solar panel surface; finally, the cutting assembly cuts the film, completing one lamination operation.

[0011] The electric lead screw of the film-pulling assembly is fixed to the worktable, and its moving end is connected to the entire traction mechanism via a connecting frame. A U-shaped support frame spans the working area, providing support and guidance. Before film pulling begins, the grippers of the clamping cylinder first clamp the two edges of the protective film. Subsequently, the electric lead screw drives the connecting frame and its slider to move along the slide rail from the end closest to the film-laying assembly towards the positioning groove, thereby smoothly pulling and flattening the protective film above the solar panel. When the slider reaches the set endpoint, it triggers the limit switch, signaling to stop the electric lead screw. After the protective film is pulled and unfolded, the clamping cylinder drives the clamping plate to descend, pressing down on the end of the protective film and providing a foundation for the roller pressing assembly.

[0012] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0018] Please refer to Figures 1 to 4 ;

[0019] This embodiment provides a solar panel surface protective film bonding device, including: a workbench 1, the upper surface of the workbench 1 is provided with a positioning groove 2 for positioning a feeding component 3, the feeding component 3 is slidably pulled out inside the positioning groove 2 for quick manual feeding, the feeding component 3 includes a solar panel frame 32 for fitting the bottom of the solar panel, the end of the solar panel frame 32 is provided with a handle 31, the workbench 1 is provided with a film feeding component 4 for releasing the protective film, a film pulling component 5 for pulling the protective film to cover the surface of the solar panel, a roller pressing component 6 located directly above the positioning groove 2 for pressing the protective film, and a cutting component 7 for cutting the protective film.

[0020] In practice, a positioning groove 2, precisely machined on the upper surface of the workbench 1, matches the shape of the feeding assembly 3. The operator can hold the handle 31 and push the feeding assembly 3 (whose core is a solar panel frame 32 supporting the solar panel) along the positioning groove 2 like a drawer, ensuring accurate feeding position each time. The protective film roll is installed on the film-laying assembly 4. During lamination, the film-pulling assembly 5 first moves, pulling the film from the film-laying assembly 4 and laying it flat on the solar panel surface above the positioning groove 2; subsequently, the roller pressing assembly 6 descends, tightly pressing the protective film onto the solar panel surface; finally, the cutting assembly 7 moves to cut the film, completing one lamination operation.

[0021] Furthermore, the film-laying assembly 4 includes a film-laying motor 41, a timing belt group 42, and a film-laying roller 43. A protective film is installed on the film-laying roller 43. The output end of the film-laying motor 41 drives the film-laying roller 43 to rotate through the timing belt group 42 to lay the film.

[0022] In practice, the film-laying assembly 4 is powered by the film-laying motor 41. The output shaft of the film-laying motor 41 transmits power to the film-laying roller 43 via a set of synchronous belts 42 (including a drive pulley, a driven pulley, and a synchronous belt). The film-laying roller 43 is fitted with a roll of protective film. When the film-pulling assembly 5 needs to pull the film, the film-laying motor 41 starts under the command of the control system, driving the film-laying roller 43 to rotate at a predetermined speed and direction via the synchronous belts 42, thereby actively and controllably releasing the protective film and preventing the film material from being stretched, deformed, or torn due to passive pulling.

[0023] Furthermore, the film-pulling assembly 5 includes an electric lead screw 51 fixed on the worktable 1. A connecting frame 52 is provided on the moving end of the electric lead screw 51. A pressing cylinder 57 located above the positioning groove 2 is fixedly connected to the connecting frame 52. A pressing plate pressing on the protective film is provided at the output end of the pressing cylinder 57. A support frame 53 with a U-shaped structure is fixedly connected to the worktable 1. Slide rails 54 are fixedly connected to the inner surfaces of both sides of the support frame 53 that are parallel to the positioning groove 2. Slider 55 is slidably connected to each slide rail 54. The slider 55 is fixedly connected to the connecting frame 52. A clamping cylinder 56 is fixedly connected to each slider 55. The clamping ends of the clamping cylinders 56 clamp the two sides of the protective film respectively. A limit switch 58 is provided on the support frame 53 at the extreme position of the slider 55.

[0024] In practice, the electric lead screw 51 of the film-pulling assembly 5 is fixed to the worktable 1, and its moving end is connected to the entire traction mechanism via the connecting frame 52. A U-shaped support frame 53 spans the working area, providing support and guidance. Before film pulling begins, the grippers of the clamping cylinder 56 first clamp the two edges of the protective film. Subsequently, the electric lead screw 51 drives the connecting frame 52 and its slider 55 to move along the slide rail 54 from the end near the film-laying assembly 4 towards the positioning groove 2, thereby smoothly pulling and flattening the protective film above the solar panel. When the slider 55 reaches the set endpoint (i.e., the film is fully covered), it triggers the limit switch 58, sending a signal to stop the electric lead screw 51. After the protective film is pulled and unfolded, the pressing cylinder 57 drives the pressing plate to descend, pressing down the end of the protective film and providing a foundation for the roller pressing assembly 6 to roll.

[0025] Furthermore, the roller pressing assembly 6 includes two gantry frames 61 for support, with at least one electric lead screw 62 and a slide bar between the two gantry frames 61. A roller pressing cylinder 63 is fixedly connected to the moving end of the electric lead screw 62, and a roller shaft 64 is rotatably connected to the output end of the roller pressing cylinder 63. A limit switch 65 is fixedly connected to the gantry frame 61 at the extreme position of the moving end of the electric lead screw 62.

[0026] In practice, the roller pressing assembly 6 is supported by two gantry frames 61 fixed on the worktable 1. A second electric screw 62 and at least one guide rod are installed parallel to each other between the two gantry frames 61. A roller pressing cylinder 63 is mounted on the moving nut of the second electric screw 62. During operation, the roller pressing cylinder 63 first drives the roller shaft 64 to descend, pressing the elastic roller surface firmly onto the protective film. Then, the second electric screw 62 drives the entire roller pressing mechanism to move along the length of the gantry frames 61 (perpendicular to the film pulling direction), causing the roller shaft 64 to roll from one end of the film to the other, expelling air from under the film and achieving a firm bond. A limit switch 65 is used to limit the starting and ending positions of the roller pressing mechanism to ensure accurate rolling range.

[0027] Furthermore, the cutting assembly 7 includes a cutting cylinder 71 fixedly connected to a gantry 61 near the film-laying assembly 4, and a cutting blade 72 is fixedly connected to the output end of the cutting cylinder 71.

[0028] In practice, the cutting component 7 is installed on one of the gantry frames 61 of the roll forming component 6 and is located at the beginning of the film pulling path (i.e., on the side closer to the film spreading component 4). After the protective film is rolled and bonded, the cutting cylinder 71 is activated, pushing the cutting blade 72 on its output end downward to pass through the gap between the bonded part and the unused film material, cutting the protective film and completing the current film application operation of the solar panel.

[0029] Furthermore, the cutting edge of the cutting tool 72 is set with a sharp angle in the middle.

[0030] In practice, to improve cutting efficiency and ensure a clean cut, the cutting edge of the cutting tool 72 is not straight; its middle section is designed with a forward-pointing angle (similar to a V-shape or a blade tip). This design allows the blade tip to first contact and pierce the membrane material during cutting, and then the two sides of the cutting edge naturally spread out to the left and right to complete the cut. This effectively reduces the single-point impact force, making the cutting process smoother, the cut cleaner, and burr-free. Furthermore, cutting from the middle avoids tearing of the protective membrane.

[0031] Furthermore, the surface of roller 64 is covered with an elastic rubber layer to increase the contact friction with the protective film and to prevent damage to the surface of the protective film during the pressing process.

[0032] In practical implementation, the surface of the metal substrate of the roller 64 of the roller pressing assembly 6 is wrapped with a layer of rubber (such as silicone or polyurethane) with a certain thickness and elasticity. This elastic rubber layer firstly increases the static friction with the surface of the protective film, ensuring that the film material can be effectively driven and air can be expelled during roller pressing, avoiding slippage; secondly, the buffering effect provided by the elastomer can evenly distribute the pressing force, effectively preventing scratches or damage to the soft protective film surface due to concentrated pressure or hard contact, and ensuring the quality of film application.
