Ultrasonic cleaning device for photovoltaic device assembly production

Abstract

This invention relates to the field of photovoltaic equipment technology and discloses an ultrasonic cleaning device for photovoltaic module production. The device includes a cleaning tank and multiple support legs installed at the bottom of the tank. A rotating roller is rotatably mounted between the inner walls of opposite sides near the top of the cleaning tank. Four sets of fixing plates are evenly fixed in pairs along the circumferential direction on the outer surface of the rotating roller. When the rotating roller drives a clamping mechanism holding the photovoltaic module to the end of the second settling tank, the surface of the fixing ring pushes the clamping block through a push plate and guide rod, allowing the clamping plates mounted on the clamping block to clamp the photovoltaic module. After cleaning the photovoltaic module, the clamping mechanism holding the photovoltaic module rotates to the first settling tank, completely releasing the photovoltaic module and allowing it to fall onto the discharge conveyor. The automatic clamping of the photovoltaic module by the clamping mechanism eliminates the need for manual clamping, effectively improving the cleaning efficiency of the photovoltaic module.

Description

Technical Field

[0001] This invention relates to the field of photovoltaic equipment technology, and in particular to an ultrasonic cleaning device for the production of photovoltaic equipment modules. Background Technology

[0002] Photovoltaics, short for solar photovoltaic power generation system, is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. The silicon wafers used in the production of these semiconductor devices must undergo rigorous cleaning. Currently, ultrasonic cleaning machines are generally used to clean the silicon wafers.

[0003] An existing ultrasonic cleaning device for photovoltaic equipment module production (publication number: CN217857719U) has at least the following drawbacks: When performing ultrasonic cleaning on photovoltaic modules, the aforementioned patent requires manual clamping of the photovoltaic modules, resulting in slow clamping efficiency and affecting the construction efficiency of the photovoltaic modules. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an ultrasonic cleaning device for photovoltaic equipment module production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An ultrasonic cleaning device for photovoltaic equipment module production includes a cleaning tank and multiple support legs installed at the bottom of the cleaning tank. A rotating roller is rotatably installed between the inner walls of opposite sides near the top of the cleaning tank. Four sets of fixing plates are evenly fixed in pairs along the circumferential direction on the outer surface of the rotating roller. The outer surfaces of the two fixing plates in each set are provided with clamping mechanisms. An ultrasonic generator and a converter are fixedly installed at the bottom of the cleaning tank. A feeding mechanism is provided on the outer surface of one side of the cleaning tank.

[0007] As a further embodiment of the present invention, the clamping mechanism includes multiple guide rods inserted through the outer surface of the fixed plate. A clamping block is fixedly installed at one end of each guide rod, and a push plate is fixedly installed at the other end of each guide rod. A clamping plate is provided on the outer surface of the clamping block, and a V-shaped groove is formed on the side of the clamping plate away from the clamping block. Fixing rings are symmetrically fixedly installed on the inner walls of opposite sides of the cleaning tank. A first sink groove and a second sink groove that communicate with each other are respectively formed on the outer surface of the fixing ring near the rotating roller. A compression spring is sleeved on the outer surface of the guide rod, and the compression spring is disposed between the fixed plate and the push plate. A vibration component is provided between the clamping plate and the interior of the cleaning tank.

[0008] As a further embodiment of the present invention, a slider is fixedly installed on the outer surface of the clamping plate near the clamping block, and a sliding groove matching the slider is opened on the side of the clamping block near the clamping plate, and the slider is slidably installed on the inner wall of the sliding groove.

[0009] As a further embodiment of the present invention, the vibration assembly includes a trapezoidal block fixedly installed on the end of the clamping plate away from the rotating roller, and multiple rotating rollers are evenly fixedly installed in an arc shape on the inner wall of the cleaning tank near its bottom.

[0010] As a further embodiment of the present invention, a return spring is fixedly installed between the end of the clamping plate away from the trapezoidal block and the end wall of the slide groove.

[0011] As a further embodiment of the present invention, the feeding mechanism includes two mounting plates symmetrically fixedly installed on the outer surface of one end of the cleaning tank, and a feeding conveyor is installed between the two mounting plates near the outer surface of the second settling tank.

[0012] As a further embodiment of the present invention, a discharge conveyor is also installed between the outer surfaces of the two mounting plates near the first settling tank. The discharge conveyor is inclined above the feeding conveyor, and a support plate is fixedly installed between the two mounting plates at the tail end of the discharge conveyor.

[0013] As a further embodiment of the present invention, an image sensor is fixedly mounted on the mounting plate near the outer surface of the feeding conveyor.

[0014] As a further embodiment of the present invention, a drive motor is fixedly installed on the outer surface of the cleaning tank, and the output end of the drive motor passes through the inner wall of the cleaning tank and is fixedly installed with the rotation center of the rotating roller.

[0015] The beneficial effects of this invention are as follows:

[0016] The rotating roller is driven by a drive motor, which in turn drives the clamping mechanism to rotate via a fixed plate. When the clamping mechanism holding the photovoltaic module rotates to the end of the second settling tank, the surface of the fixed ring pushes the clamping block through the push plate and guide rod, allowing the clamping plates installed on the clamping block to clamp the photovoltaic module, so that the photovoltaic module can be immersed in the cleaning liquid in the cleaning tank for cleaning. After the photovoltaic module is cleaned, the clamping mechanism holding the photovoltaic module will rotate to the first settling tank, so that the clamping mechanism completely releases the photovoltaic module, allowing the cleaned photovoltaic module to fall onto the discharge conveyor for discharge, facilitating subsequent unloading of the cleaned photovoltaic module. The automatic clamping of the photovoltaic module by the clamping mechanism eliminates the need for manual clamping, effectively improving the cleaning efficiency of the photovoltaic module.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] See attached document Figure 1 -Appendix Figure 7An ultrasonic cleaning device for photovoltaic equipment module production includes a cleaning tank 1 and multiple support legs 25 installed at the bottom of the cleaning tank 1. A rotating roller 3 is rotatably mounted between the inner walls of opposite sides near the top of the cleaning tank 1. Four sets of fixing plates 4 are evenly fixed in pairs along the circumferential direction on the outer surface of the rotating roller 3. Each set of two fixing plates 4 has a clamping mechanism on their opposite outer surfaces. An ultrasonic generator 2 and a converter 26 are fixedly mounted at the bottom of the cleaning tank 1. A feeding mechanism is provided on one side of the outer surface of the cleaning tank 1. A drive motor 23 is fixedly mounted on the outer surface of the cleaning tank 1. The output end of the drive motor 23 penetrates the inner wall of the cleaning tank 1 and is fixedly mounted to the rotation center of the rotating roller 3. The clamping mechanism includes multiple guide rods 5 inserted through the outer surface of the fixing plates 4. A clamping block 6 is fixedly installed at one end, and a push plate 7 is fixedly installed at the other end of multiple guide rods 5. A clamping plate 9 is provided on the outer surface of the clamping block 6. A V-shaped groove 10 is opened on the side of the clamping plate 9 away from the clamping block 6. Fixing rings 14 are symmetrically fixedly installed on the inner walls of opposite sides of the cleaning tank 1. A first sink groove 15 and a second sink groove 16 that are interconnected are opened on the outer surface of the fixing ring 14 near the rotating roller 3. A compression spring 8 is sleeved on the outer surface of the guide rod 5. The compression spring 8 is set between the fixing plate 4 and the push plate 7. A vibration component is provided between the clamping plate 9 and the interior of the cleaning tank 1. A slider 11 is fixedly installed on the outer surface of the clamping plate 9 near the clamping block 6. A sliding groove 12 that matches the slider 11 is opened on the side of the clamping block 6 near the clamping plate 9. The slider 11 is slidably installed on the inner wall of the sliding groove 12.

[0028] In use, the photovoltaic module to be cleaned is placed on the feeding conveyor 19, which transports the photovoltaic module to the V-groove 10 between two opposing clamping plates 9 for support. After the photovoltaic module is fully pushed between the two clamping plates 9, the drive motor 23 drives the rotating roller 3 to rotate, which in turn drives the clamping mechanism to rotate via the fixed plate 4. When the clamping mechanism containing the photovoltaic module rotates to the end of the second sink 16, the surface of the fixed ring 14 pushes the clamping block 6 via the push plate 7 and the guide rod 5, so that the clamping plate 9 installed on the clamping block 6 can clamp the photovoltaic module, thereby causing the photovoltaic module to sink into the cleaning liquid in the cleaning tank 1. The ultrasonic generator 2 and the converter 26 generate high-frequency microbubbles in the cleaning liquid to break the adhesion of dirt and impurities on the surface of the photovoltaic module, thereby achieving the cleaning effect.

[0029] In this embodiment, the vibration assembly includes a trapezoidal block 21 fixedly installed on the end of the clamping plate 9 away from the rotating roller 3. Multiple rotating rollers 22 are evenly and fixedly installed in an arc shape on the inner wall of the cleaning tank 1 near its bottom. A return spring 13 is fixedly installed between the end of the clamping plate 9 away from the trapezoidal block 21 and the end wall of the slide 12.

[0030] When the rotating roller 3 drives the clamping mechanism to rotate into the cleaning tank 1 through the fixed plate 4, the trapezoidal block 21 installed at the end of the clamping plate 9 will contact the rotating roller 22, so that the trapezoidal block 21 can pass through the rotating roller 22 in sequence, thereby driving the clamping plate 9 to move on the clamping block 6. With the use of the reset spring 13, the clamping mechanism can achieve a slight vibration effect, so as to better remove impurities from the photovoltaic module.

[0031] In this embodiment, the feeding mechanism includes two mounting plates 17 symmetrically fixedly installed on the outer surface of one end of the cleaning tank 1. A feeding conveyor 19 is installed between the two mounting plates 17 near the outer surface of the second settling tank 16. A discharge conveyor 18 is also installed between the two mounting plates 17 near the outer surface of the first settling tank 15. The discharge conveyor 18 is inclinedly arranged above the feeding conveyor 19, and a support plate 24 is fixedly installed between the two mounting plates 17 at the tail end of the discharge conveyor 18.

[0032] In this embodiment, an image sensor 20 is fixedly installed on the mounting plate 17 near the outer surface of the feeding conveyor 19. The image sensor 20 is used to detect whether the clamping mechanism is aligned with the discharge end of the feeding conveyor 19, so that the feeding conveyor 19 can accurately push the photovoltaic module between the clamping mechanisms.

[0033] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: In use, the photovoltaic module to be cleaned is placed on the feeding conveyor 19, so that the feeding conveyor 19 conveys the photovoltaic module to the V-groove 10 between the two clamping plates 9 arranged opposite each other, and supports the photovoltaic module; after the photovoltaic module is completely pushed between the two clamping plates 9, the drive motor 23 drives the rotating roller 3 to rotate, so that the rotating roller 3 drives the clamping mechanism to rotate through the fixed plate 4. When the clamping mechanism with the photovoltaic module is placed rotates to the end of the second sink 16, the surface of the fixed ring 14 will push the clamping block 6 through the push plate 7 and the guide rod 5, so that the clamping plate 9 installed on the clamping block 6 can clamp the photovoltaic module, so as to drive the photovoltaic module to sink into the cleaning liquid in the cleaning tank 1, so that the ultrasonic generator 2 and the converter 26 generate high-frequency micro bubbles to the cleaning liquid to destroy the adhesion of dirt and impurities on the surface of the photovoltaic module, thereby achieving the cleaning effect;

[0034] When the rotating roller 3 drives the clamping mechanism to rotate into the cleaning box 1 through the fixed plate 4, the trapezoidal block 21 installed at the end of the clamping plate 9 will contact the rotating roller 22, so that the trapezoidal block 21 can pass through the rotating roller 22 in sequence, thereby driving the clamping plate 9 to move on the clamping block 6. With the use of the reset spring 13, the clamping mechanism can achieve a slight vibration effect, so as to better remove impurities from the photovoltaic module.

[0035] After the photovoltaic modules are cleaned, the clamping mechanism holding the photovoltaic modules will rotate to the first sink 15, so that the clamping mechanism completely releases the photovoltaic modules, allowing the cleaned photovoltaic modules to fall onto the discharge conveyor 18 for discharge, facilitating the subsequent removal of the cleaned photovoltaic modules.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
