Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic panel testing technology, specifically to a testing device and testing method for solar photovoltaic panels used in production. Background Technology

[0002] Solar photovoltaic panels are devices that absorb sunlight and convert solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or photochemical effect. The main material of most solar panels is silicon. During the production of solar photovoltaic panels, factors such as manual contact and operating environment can cause damage to the solar photovoltaic panels, so special testing equipment is needed to test the solar photovoltaic panels. However, existing solar photovoltaic panel testing devices are inefficient because they rely on manual movement of the searchlight for inspection. This significantly reduces the device's testing efficiency. Furthermore, during the production process, solar photovoltaic panels may become stained, or lint and hair from workers may fall onto the surface, affecting the accuracy of the searchlight's inspection.

[0024] Two square plates 511 are fixedly connected to the upper surface of the end of the slide bar 51 away from the push plate 5. Fixed plates 521 are fixedly connected to both sides of the transverse guide rail 52. A bidirectional telescopic rod 53 is rotatably connected between the ends of the fixed plates 521 away from the transverse guide rail 52. One output end of the bidirectional telescopic rod 53 is rotatably connected between the two square plates 511. The purpose of this arrangement is to facilitate the rotation of the bidirectional telescopic rod 53 by the movement of the slide bar 51.

[0025] Two square plates 601 are fixedly connected to the lower end of the holding guide rail 6 away from the transport compartment 1. The end of the bidirectional telescopic rod 53 away from the square plate 511 is rotatably connected between the two square plates 601. The purpose of this arrangement is to facilitate the movement of the holding guide rail 6 by rotating the bidirectional telescopic rod 53.

[0026] A return spring 54 is fixedly connected to the center of the side of the push plate 5 away from the transport bin 1. The end of the return spring 54 away from the push plate 5 is fixedly connected to the inner wall of the feeding bin 2. The purpose of this arrangement is to make it easy to reset the feeding mechanism by using the elasticity of the return spring 54 when the mounting block 33 is separated from the push plate 5.

[0027] Working principle: The solar photovoltaic panels are transported between two holding rails 6. The motor 4 is started, and through the transmission of the belt 44, the motor 4 drives the rotating shaft 32 to rotate. The power gear 31 then rotates synchronously with the rotating shaft 32. Through the meshing of the power gear 31 with the movable hinge 3 and the meshing of the movable hinge 3 with the internal gear guide rail 11, the movable hinge 3 rotates along the trajectory of the internal gear guide rail 11 while simultaneously sliding within the limiting rail 101, supporting the movable hinge 3 and ensuring its movement along the trajectory of the internal gear guide rail 11. When both ends of the rotating shaft 32 are within the limiting rail 101... When the 01 moves downwards and towards the side closer to the loading bin 2, the lower end of the mounting block 33 will press against the push plate 5, compressing the return spring 54, which in turn pushes the slide rod 51 to move into the upper loading bin 2. The angle between the bidirectional telescopic rod 53 and the slide rod 51 increases, and the bidirectional telescopic rod 53 rotates. When the bidirectional telescopic rod 53 moves to a vertical position, the slide rod 51 continues to move towards the side closer to the loading bin 2. After that, the angle between the bidirectional telescopic rod 53 and the slide rod 51 decreases, and it extends, allowing the solar photovoltaic panels located on the holding guide rail 6 to be transported. The movable hinge 3 continues to rotate around the internal toothed guide rail 11. When the hinge 3 rises, the solar photovoltaic panel is positioned directly above the support seat 341, allowing it to be lifted and transported. Afterwards, the mounting block 33 disengages from the push plate 5, and the return spring 54 stretches, causing the push plate 5 to move in the opposite direction, thus resetting the feeding mechanism for future feeding of the solar photovoltaic panel. As the solar photovoltaic panel moves along the holding guide rail 6, its surface contacts the adsorption roller 211, adsorbing dirt and impurities to improve the accuracy of the detection device. Then, the transport plate 34 moves along the rotating shaft 32 to the upper motion track, where the limiting protrusion 111... The conveyor plate 34 will enter the limiting groove 3401 to guide and limit the transport plate 34, preventing the rotating shaft 32 on the side away from the loading bin 2 from falling into the wrong track of the limiting track 101, thus ensuring the stability of the transport of the solar photovoltaic panel. The surface of the solar photovoltaic panel can be detected by the searchlight 115 and the data can be transmitted to the display 114 for easy observation. When the conveyor plate 34 continues to move and descends along the trajectory of the internal tooth track 11, the solar photovoltaic panel will detach from the support seat 341 and be transported above the unloading plate 116, making it easy to remove the solar photovoltaic panel and for the device to transport the solar photovoltaic panel again. Example 2

[0028] A testing device and method for solar photovoltaic panels used in production, characterized by comprising the following steps: Step 1: The rotating shaft 32 rotates, and the power gear 31 rotates synchronously with the rotating shaft 32. Through the meshing of the power gear 31 with the movable hinge 3 and the meshing of the movable hinge 3 with the internal tooth guide rail 11, the movable hinge 3 can rotate along the trajectory of the internal tooth guide rail 11 while rotating. Step 2: When the two ends of the rotating shaft 32 are under the limit track 101 and move towards the side closer to the feeding bin 2, the lower end of the mounting block 33 will squeeze the push plate 5, the reset spring 54 will be compressed, and then push the slide rod 51 to move into the upper feeding bin 2. The angle between the bidirectional telescopic rod 53 and the slide rod 51 will increase, and the bidirectional telescopic rod 53 will rotate. Step 3: The movable hinge 3 continues to rotate around the internal toothed guide rail 11. When the movable hinge 3 rises, the solar photovoltaic panel is just above the support seat 341. Then the solar photovoltaic panel can be lifted and transported. After that, the mounting block 33 is separated from the push plate 5, and the return spring 54 is stretched to make the push plate 5 move in the opposite direction, which can then reset the feeding mechanism. Step four: The transport plate 34 moves with the rotating shaft 32 to the upper motion track. The limiting protrusion 111 will enter the limiting groove 3401 to guide and limit the transport plate 34, preventing the rotating shaft 32 on the side away from the loading bin 2 from falling into the wrong track of the limiting track 101.
