Description

Technical Field

[0001] This utility model relates to the field of photovoltaic glass coating technology, and in particular to a coating fixture for high-reflectivity photovoltaic glass. Background Technology

[0002] During the processing of high-reflectivity photovoltaic glass, a coating is applied to optimize optical performance, enhance weather resistance, and improve mechanical strength, thereby significantly improving the power generation efficiency of photovoltaic modules, extending their service life, and reducing overall costs.

[0003] Double-layer coating of high-reflectivity photovoltaic glass can increase the light transmittance to over 94% by adjusting the thickness of the bottom and top layers and utilizing the principle of light interference. However, most double-sided coating of high-reflectivity photovoltaic glass currently uses manual flipping, which is inefficient. The existing publicly available technical solution, CN221479808U, discloses a photovoltaic glass coating device, including a coating frame, with coating devices at both ends of the coating frame, and support plates slidably arranged on both sides of the coating frame through an adjustment mechanism. A flipping clamping mechanism is arranged between the support plates on both sides of the coating frame, and the flipping clamping mechanism is used to clamp the photovoltaic glass and flip it.

[0004] In actual implementation, the above technical solution requires a flipping clamping mechanism to flip the photovoltaic glass by meshing the rack with the rotating seat. The flipping clamping mechanism flips every time it passes the rack, so a coating device needs to be set on both sides of the flipping clamping mechanism to achieve double-sided coating of the photovoltaic glass. The cost of setting up two sets of coating devices is relatively high. Summary of the Invention

[0005] The purpose of this utility model is to provide a coating fixture for high-reflectivity photovoltaic glass. Through the setting of a lifting hydraulic cylinder, the lifting hydraulic cylinder can drive the lifting plate to move upward. The lifting plate retracts into the lifting sleeve, and the flipping gear can move away from the flipping rack. The clamping flipping component moves normally and is not driven by the flipping rack to flip the photovoltaic glass. Only one set of coating components is set to achieve double-sided coating, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a coating fixture for high-reflectivity photovoltaic glass, comprising a conveying assembly, a clamping and flipping assembly installed on the inner side of the conveying assembly, and a coating assembly for coating on one side of the clamping and flipping assembly.

[0018] 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.

[0019] This utility model provides a technical solution: Please see Figures 1 to 5 A coating fixture for high-reflectivity photovoltaic glass includes a conveying assembly 1, a clamping and flipping assembly 2 installed inside the conveying assembly 1, and a coating assembly 3 for coating is provided on one side of the clamping and flipping assembly 2. The conveying assembly 1 includes a guide rail 101, and a slidable lead screw slider 105 is disposed above the guide rail 101; The clamping and flipping assembly 2 includes a lifting sleeve 206 fixed to the bottom of the lead screw slider 105. A lifting hydraulic cylinder 207 is bolted inside the lifting sleeve 206, and a lifting plate 208 is fixed to the telescopic end of the lifting hydraulic cylinder 207. A flipping shaft 209 passes through the inside of the lifting plate 208. A flipping gear 204 is fixed to one end of the flipping shaft 209, and a flipping rack 205 is meshed with the lower part of the flipping gear 204.

[0020] A limiting component 4 is provided on the side of the flip shaft 209. The limiting component 4 includes a limiting insertion hole 405 opened inside the flip shaft 209, and a limiting rod 404 is provided on the side of the limiting insertion hole 405. An electromagnet 402 is sleeved on the outside of the limiting rod 404, and an iron block 401 is fixed to the end of the limiting rod 404. A return spring 403 is provided between the iron block 401 and the lifting plate 208. The electromagnet 402 is embedded in the side of the lifting plate 208. A clamping frame 201 is fixedly connected to the other end of the flip shaft 209, and the clamping frame 201 is located inside the lifting plate 208.

[0021] By adopting the above technical solution, when the lead screw slider 105 drives the clamping and flipping assembly 2 to move, the flipping gear 204 reaches above the flipping rack 205. At this time, the clamping and flipping assembly 2 continues to move. Under the action of the flipping rack 205, the flipping gear 204 rotates. The flipping gear 204 can drive the photovoltaic glass to rotate and flip through the clamping and flipping assembly 2. When the clamping and flipping assembly 2 moves from one end of the flipping rack 205 to the other end, the photovoltaic glass achieves a 180° flip. When it is not necessary to flip the photovoltaic glass, the lifting hydraulic cylinder 207 can be activated. The lifting hydraulic cylinder 207 drives the lifting plate 208 to move upward. The lifting plate 208 retracts into the lifting sleeve 206, and the flipping gear 204 can move away from the flipping rack 205. The clamping and flipping assembly 2 moves normally without being affected by the flipping rack 205. Driven by 5, on the other hand, when the photovoltaic glass is flipped, the electromagnet 402 can be energized at the same time. The electromagnet 402 attracts the iron block 401, and the iron block 401 drives the limiting rod 404 to be inserted into the limiting hole 405, thus limiting the flipping shaft 209. The electromagnet 402 is energized when the flipping gear 204 reaches one end of the flipping rack 205, thereby limiting the flipping gear 204. Through the set lifting hydraulic cylinder 207, the lifting hydraulic cylinder 207 can drive the lifting plate 208 to move upward. The lifting plate 208 retracts into the lifting sleeve 206, and the flipping gear 204 can move away from the flipping rack 205, clamping the flipping component 2 to move normally. It is not driven by the flipping rack 205 to drive the photovoltaic glass to flip. Only one set of coating components 3 is set to achieve double-sided coating.

[0022] Specifically, such as Figure 2 and Figure 3 As shown, the clamping frame 201 is internally threaded with a clamping screw 202, and the bottom of the clamping screw 202 is connected to a clamping plate 203 via a bearing. A rubber pad 210 is attached to the surface of the clamping frame 201 below the clamping plate 203. The conveying assembly 1 also includes a top bracket 102 located below the guide rail 101. Side brackets 103 are provided on both the left and right sides of the top bracket 102. A conveying screw 104 is rotatably connected inside the top bracket 102. The conveying screw 104 is threadedly connected to the screw slider 105 via a screw nut. The rotating rack 205 is embedded inside the guide rail 101. One end of the conveying screw 104 is connected to a servo motor. The controller electrically controls the two sets of servo motors, and the two sets of servo motors work synchronously.

[0023] The coating assembly 3 includes a coating bracket 301 fixed to the outside of the top bracket 102. A coating liquid tank 302 is provided on the top of the coating bracket 301, and the output end of the coating liquid tank 302 is connected to a coating liquid nozzle 303 through a pipe. A coating liquid pump body is provided on the pipe.

[0024] By adopting the above technical solution, the photovoltaic glass is placed between two sets of clamping frames 201. Rotating the clamping screw 202 pushes the clamping plate 203 to slide inside the clamping frame 201. The clamping plate 203 moves towards the rubber pad 210, clamping the photovoltaic glass. The servo motors, driven by the controller, work synchronously, causing the two sets of transmission screws 104 to rotate synchronously. Under the action of the screw nut, the screw slider 105 slides on the top support 102, thereby moving the photovoltaic glass and allowing it to move. The glass enters the inner side of the coating bracket 301. The coating liquid pump delivers the coating liquid from the coating liquid tank 302 to the coating liquid nozzle 303. The coating liquid is sprayed onto the photovoltaic glass through the coating liquid nozzle 303. A drying component is set on one side of the coating component 3. The drying component includes a heating wire and a fan. The heating wire heats the surrounding space, and the fan blows hot air onto the surface of the photovoltaic glass to dry the photovoltaic glass. Through the set conveying component 1, the photovoltaic glass is clamped between the clamping frames 201, so that the photovoltaic glass enters the inner side of the coating bracket 301 to achieve the coating treatment.

[0025] Working principle: Electromagnet 402 attracts iron block 401, iron block 401 drives limit rod 404 to insert into limit hole 405, limiting the flip shaft 209. This activates lifting hydraulic cylinder 207, which moves lifting plate 208 upwards. Lifting plate 208 retracts into lifting sleeve 206, allowing flip gear 204 to move away from flip rack 205. The flip assembly 2 moves normally, and photovoltaic glass is placed between two sets of clamping frames 201. Rotating clamping screw 202 pushes clamping plate 203 within the clamping frame. The inner side of the frame 201 slides, and the clamping plate 203 moves towards the rubber pad 210 to clamp the photovoltaic glass. Driven by the controller, two servo motors work synchronously, driving two sets of lead screws 104 to rotate synchronously. Under the action of the lead screw nut, the lead screw slider 105 slides on the top support 102, thus moving the photovoltaic glass into the inner side of the coating support 301. The coating liquid pump delivers the coating liquid from the coating liquid tank 302 to the coating liquid nozzle 303, through which the photovoltaic glass is coated. The coating solution is sprayed, and a drying component is installed on one side of the coating assembly 3 to achieve coating drying. Then, the clamping and flipping assembly 2 moves in the reverse direction and returns to its initial position. Subsequently, the lifting hydraulic cylinder 207 drives the lifting plate 208 to move downward, and the flipping gear 204 decreases in height and can mesh with the flipping rack 205. At this time, the lead screw slider 105 drives the clamping and flipping assembly 2 to move, and the flipping gear 204 reaches above the flipping rack 205. At this time, the electromagnet 402 is de-energized, and the return spring 403 drives the limit plug 404 away from the limit plug hole 405, releasing the flipping shaft 209. The lock, clamping and flipping component 2, moves continuously. Under the action of the flipping rack 205, the flipping gear 204 rotates. The flipping gear 204 can drive the photovoltaic glass to rotate and flip through the clamping and flipping component 2. When the clamping and flipping component 2 moves from one end of the flipping rack 205 to the other end of the flipping rack 205, the photovoltaic glass achieves a 180° flip. Then, the electromagnet 402 attracts the iron block 401. The iron block 401 drives the limiting rod 404 to be inserted into the limiting hole 405 to limit the flipping shaft 209. The flipped photovoltaic glass reaches the coating component 3 again to achieve secondary coating.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
