Description

Technical Field

[0001] This utility model relates to the technical field of photovoltaic glass panel production, specifically to a device for removing adhesive from the edges of photovoltaic glass panels. Background Technology

[0002] Photovoltaic glass panels are transparent glass materials used in photovoltaic cell modules. They have high light transmittance and excellent weather resistance. During the production process of photovoltaic glass panels, adhesives or glues are usually used to fix different components together. However, glue residue on the edges of the glass panels can affect the aesthetics, sealing, and subsequent splicing operations of the photovoltaic modules. In order to ensure the quality of the glass panels and the overall performance of the modules, the edges of the glass panels usually need to be manually removed, which is inefficient.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent with announcement number CN119635502A, announcement date March 18, 2025) provides a residual adhesive removal mechanism for photovoltaic modules, comprising: a worktable, multiple sets of adhesive grinding components, a shifting device, and a robotic arm; the surface of the worktable is raised to form a storage platform, and the outer periphery of the storage platform is recessed to form a collection chamber; the shifting device includes a longitudinal part, a transverse part, and a driving component; the longitudinal part is fixedly disposed on the outer peripheral wall of the collection chamber, one end of the transverse part is fixedly connected to each set of adhesive grinding components, and the other end of the transverse part is movably disposed on the driving component; the robotic arm is disposed above the worktable; the adhesive grinding components are disposed at the edge of the frameless photovoltaic module, and when the driving component is activated, each set of adhesive grinding components moves along the edge of the frameless photovoltaic module, thereby removing the adhesive on the frameless photovoltaic module. This invention uses the shifting device to drive each set of adhesive grinding components to move along the edge of the frameless photovoltaic module, thereby completing the corresponding adhesive removal process, thus enabling the photovoltaic module to continue to be recycled as a whole glass panel after the frame is removed.

[0004] While existing technologies use abrasive components for adhesive removal, the overall structure is quite complex. Furthermore, the intelligent control system of the robotic arm increases operational complexity and maintenance difficulty. Additionally, due to limitations in the shape of the adhesive removal blades or the design of the adhesive removal machine, stubborn adhesive residue can easily remain on the edges and corners of the photovoltaic glass panel, further affecting the adhesive removal effect.

[0005] To address the aforementioned issues, there is an urgent need for innovative designs based on existing adhesive removal equipment used for the edges of photovoltaic glass panels. Therefore, we propose an adhesive removal device for the edges of photovoltaic glass panels that can effectively solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a device for removing adhesive from the edges of photovoltaic glass panels, in order to solve the problems mentioned in the background art. Currently, adhesive removal is performed using abrasive components, but the overall structure is relatively complex. Furthermore, the intelligent control system of the robotic arm increases the complexity of operation and maintenance. Additionally, due to limitations in the shape of the adhesive removal blades or the design of the adhesive removal machine, stubborn adhesive residue is easily left on the corners of the photovoltaic glass panels, further affecting the adhesive removal effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a descaling device for the edge of a photovoltaic glass panel, comprising a descaling machine with an inlet and an outlet, guide rollers symmetrically arranged on both sides of the inlet and outlet, a conveyor belt structure installed inside the descaling machine, an edge descaling component on the side of the outlet, a collection frame at the bottom of the descaling machine, a pull-out drawer installed inside the collection frame, and an edge descaling component connected to the descaling machine via a guide assembly.

[0008] Preferably, the guiding assembly includes a movable guide rail mounted on the adhesive remover, and a movable seat is slidably connected to the movable guide rail, the movable seat being connected to the movable guide rail by a bolt structure.

[0009] Preferably, a temporary storage box is installed on the movable base, and an edge adhesive removal part is provided at the bottom of the temporary storage box.

[0010] Preferably, the adhesive remover is provided with an auxiliary component, which includes a short-side support base and a long-side support base installed on the adhesive remover.

[0011] Preferably, a short-side guide rail is installed on the short-side support base, and a short-side suction cup is slidably connected to the short-side guide rail.

[0012] Preferably, a long-side guide rail is installed on the long-side support base, and a long-side suction cup is slidably connected to the long-side guide rail.

[0013] Preferably, the side of the temporary storage box is connected to the outside gas through a conveying pipe, and a nozzle is installed at the bottom of the temporary storage box, with the nozzle located above the edge adhesive removal part.

[0014] Preferably, a baffle and a filter plate are installed inside the nozzle, and a lifting component is connected through the filter plate. The lifting component is I-shaped, and a through groove adapted to the bottom shape of the lifting component is opened on the baffle. A spring is sleeved on the outside of the lifting component.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This adhesive removal device for the edge of photovoltaic glass panels facilitates the introduction of photovoltaic glass panels into the inlet. Guide rollers symmetrically installed on both sides of the inlet roll and limit the movement of the glass panel, ensuring that the glass panel enters the equipment in a straight line, avoiding deviation that could lead to inaccurate adhesive removal. The edge adhesive removal component adheres to the edge of the glass panel to scrape away residual adhesive, completing the core adhesive removal operation. The corner adhesive removal component on the side of the outlet initially removes stubborn residual adhesive from the corners of the glass panel, improving the overall adhesive removal quality. The specific details are as follows: Through the coordinated action of multiple positioning structures, the adhesive removal operation is ensured to be accurate and error-free. The guide rollers on both sides of the inlet guide the glass plate into the equipment in a straight line by rolling limit, avoiding initial deviation and ensuring that the edge adhesive removal parts are accurately attached to the edge of the glass plate. The corner adhesive removal parts on the side of the outlet perform preliminary removal of stubborn residual adhesive, further improving the adhesive removal quality.

[0016] After the short and long side suction cups move along the corresponding guide rails, they firmly fix the glass plate by negative pressure multi-point adsorption to prevent displacement during adhesive removal. The multi-positioning and fixing design ensures accuracy throughout the entire process from plate entry, adhesive removal to plate exit, effectively avoiding problems such as incomplete adhesive removal or component damage caused by displacement.

[0017] The collection frame at the bottom of the equipment and the internal pull-out drawer form an efficient waste collection system, solving the problem of glue residue pollution at the source. The movable seat is slidably connected to the movable guide rail by bolts, and its position can be adjusted according to different sized glass plates without the need to replace special clamps.

[0018] The guide rollers at the inlet and outlet guide the movement of the components through rolling contact, reducing scratches on the glass surface caused by sliding friction. The initial clamping of the corner adhesive removal components and the precise scraping of the edge adhesive removal components prevent damage to the component edges due to excessive adhesive removal force. From fixing to conveying to adhesive removal, the entire process protects the components and reduces product scrap rates.

[0019] When the gas is sprayed out through the nozzle, it blows away the adhesive residue, preventing it from adhering to the edge adhesive removal parts and affecting the operation. On the other hand, the gas flow can cool the adhesive removal area, reduce the wear caused by frictional heat on the edge adhesive removal parts, and extend their service life.

[0022] 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.

[0023] Example 1: In this example, the corner adhesive removal component 6 at the side end of the outlet 5 initially removes stubborn residual adhesive from the corners of the glass plate, improving the overall adhesive removal quality. Figures 1-5The technical solution shown includes a glue remover 1 with an inlet 2 and an outlet 5. Guide rollers 3 are symmetrically arranged on both sides of the inlet 2 and outlet 5. A conveyor belt structure 4 is installed inside the glue remover 1. An edge glue remover 6 is provided on the side of the outlet 5. A collection frame 7 is provided at the bottom of the glue remover 1, and a pull-out drawer 8 is installed inside the collection frame 7. An edge glue remover 18 is connected to the glue remover 1 via a guide assembly. The guide assembly includes a movable guide rail 15 mounted on the glue remover 1, and a movable seat 16 is slidably connected to the movable guide rail 15. The movable seat 16 is bolted to the movable guide rail 15. A temporary storage box 17 is mounted on the movable seat 16, and an edge adhesive removal component 18 is provided at the bottom of the temporary storage box 17. The inlet 2 of the adhesive removal machine 1 facilitates the introduction of photovoltaic glass panels. At this time, the guide rollers 3 symmetrically installed on both sides of the inlet 2 roll and limit the movement of the glass panels, ensuring that the glass panels enter the equipment in a straight line and avoiding deviation that would lead to inaccurate adhesive removal. The conveyor belt structure 4 installed inside the adhesive removal machine 1 is used to receive the glass panels entering from the inlet 2 and conveys the glass panels to the adhesive removal area through uniform speed transmission. The movable seat 16 is equipped with a temporary storage box 17. The bolted structure is slidably connected to the moving guide rail 15. Before operation, the position of the glass plate can be adjusted along the moving guide rail 15 according to its position. After adjustment, the bolts are tightened to fix it. The bolt fixing method is simple to operate and firmly fixed, avoiding the displacement of the adhesive removal caused by the loosening of the moving seat 16 after adjustment. The temporary storage box 17 on the moving seat 16 facilitates the scraping of residual adhesive by the edge adhesive removal part 18 against the edge of the glass plate, completing the core adhesive removal operation. The collection frame 7 is set at the bottom of the adhesive removal machine 1. The adhesive debris and impurities generated during adhesive removal fall into the collection frame 7 under the action of gravity, avoiding adhesive debris splashing and contaminating the glass plate or the internal structure of the equipment. The structure maintains a clean working environment. When the amount of adhesive residue collected in the drawer 8 reaches a certain level, the operator can directly pull out the drawer 8 to dump the waste material without disassembling the equipment, which is convenient for maintenance. The overall structure is simple, reducing the problem of complicated operation caused by complex structures. After the adhesive is removed, the photovoltaic glass panel is moved out through the outlet 5. At this time, the corner adhesive removal parts 6 on the side of the outlet 5 perform preliminary removal of stubborn residual adhesive on the corners of the glass panel, which improves the overall adhesive removal quality. The guide rollers 3 on both sides of the outlet 5 assist the glass panel in moving, making the glass panel move more stably and ensuring the integrity of the finished product.

[0024] Example 2: In this example, during operation, the glass plate can be adjusted along the guide rail to fit the short and long sides. Negative pressure adsorption firmly fixes the glass plate to the conveyor belt structure 4, ensuring no displacement of the glass plate during the operation of the edge adhesive removal component 18. Specifically, as follows... Figures 1-5As shown, the adhesive removal machine 1 is equipped with auxiliary components, including a short-side support base 9 and a long-side support base 12 mounted on the adhesive removal machine 1. A short-side guide rail 10 is mounted on the short-side support base 9, and a short-side suction cup 11 is slidably connected to the short-side guide rail 10. A long-side guide rail 13 is mounted on the long-side support base 12, and a long-side suction cup 14 is slidably connected to the long-side guide rail 13. The short-side support base 9 and the long-side support base 12 are respectively fixed inside the adhesive removal machine 1 at positions corresponding to the short and long sides of the glass plate, providing stable support for the guide rails. The short-side guide rail 10 is mounted on the short-side support base 9, and its extension direction is parallel to the short side of the glass plate. The long-side guide rail 13 is mounted on the long-side support base 12. 2. The extension direction is parallel to the long side of the glass plate, and the extension direction of the guide rail is parallel to the edge of the glass plate. The short side suction cup 11 and the long side suction cup 14 are slidably connected to the short side guide rail 10 and the long side guide rail 13, respectively. During operation, they can be adjusted along the guide rail to fit the short and long sides of the glass plate. The glass plate is firmly fixed on the conveyor belt structure 4 by negative pressure adsorption, ensuring that the glass plate does not shift when the edge adhesive removal part 18 is working. The negative pressure adsorption method will not cause indentation or damage to the surface of the glass plate. At the same time, multi-point adsorption ensures that the glass plate is evenly stressed and completely fixed without loosening, providing an absolutely stable foundation for the precise operation of the edge adhesive removal part 18 and greatly improving the adhesive removal accuracy. Example 3: In this example, gas enters the temporary storage box 17 through the delivery pipe 19 for temporary storage. The gas in the temporary storage box 17 is sprayed out through the nozzle 20 to facilitate the adhesive removal operation. Specifically, as shown below... Figures 5-8 As shown, the side of the temporary storage box 17 is connected to the outside gas through a conveying pipe 19. A nozzle 20 is installed at the bottom of the temporary storage box 17, located above the edge adhesive removal component 18. A baffle 21 and a filter plate 24 are installed inside the nozzle 20. A lifting component 23 is connected through the filter plate 24. The lifting component 23 is I-shaped. A through groove 22 adapted to the shape of the bottom of the lifting component 23 is opened on the baffle 21. A spring 25 is sleeved on the outside of the lifting component 23. The temporary storage box 17 is connected to the outside gas source through the conveying pipe 19. The gas enters the temporary storage box 17 through the conveying pipe 19 for temporary storage. The gas in the temporary storage box 17 is sprayed out through the nozzle 20, which facilitates the adhesive removal operation. At the same time, the gas flow can be used to... The adhesive removal area is cooled to reduce wear caused by frictional heat on the edge adhesive removal component 18. In the initial state, the spring 25 is in a naturally extended state. The gas pushes the I-shaped lifting component 23 to move down, and its bottom moves out of the through groove 22 of the baffle 21, so that the gas inside the nozzle 20 is output through the filter plate 24 and the through groove 22. When the delivery pipe 19 stops supplying gas, the lifting component 23 moves up by the elastic force of the spring 25, and the bottom of the lifting component 23 is locked into the through groove 22, so that the gas flow channel inside the nozzle 20 is closed, reducing the problem of contamination of the nozzle 20 and extending the service life of the nozzle 20. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
