Description

Technical Field

[0001] The utility model relates to the technical field of solar cell defect detection, and particularly relates to a solar photovoltaic module cell defect detector. Background Technique

[0002] Solar cells are the core part of solar photovoltaic panels, and their main function is to convert sunlight into electrical energy. Solar cells utilize the photovoltaic effect of semiconductor materials. When sunlight shines on the surface of the cell, photons interact with the materials in the cell, causing electrons to escape from the materials and form an electric current. These electric currents can be collected and utilized to generate electricity. During the production and processing of solar cells, sometimes the surface of the produced solar cells has defects, which are very likely to affect the product quality. Therefore, it is very necessary to detect defects of different sizes on the surface of solar cells. At this time, this type of solar cell surface defect detection device is required. This device uses a vision detection camera to take pictures of the surface of solar cells and transmits the captured video images to a terminal device. The staff compares them with the image information of qualified solar cells to detect the defects of solar cells. In the existing patent application with the application number CN202223101165.7, a device for solar surface defect detection is proposed. Although it can drive two fixing plates to approach the solar panel simultaneously through a driving component, achieving the fixation and clamping of the solar panel, and avoiding the problem that the solar panel is prone to move on the detection table surface during the detection process, resulting in inaccurate detection or detection failure, when the driving component drives the two fixing plates to clamp and fix the solar panel, the fixing plates are prone to bend the solar panel, making it difficult for the vision detection camera to capture a clear and comprehensive image of the solar panel, and further affecting the normal detection of the solar panel. Therefore, it needs to be improved. Content of the Utility Model

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown in the figure, a defect detector for solar photovoltaic module cells includes a conveyor main body 1, on which a conveyor belt 6 is installed. At the upper end of the conveyor main body 1, a gantry 2 is fixedly installed. On the upper side wall of the gantry 2, two guide rail grooves 7 are symmetrically opened. At the lower end of the upper side wall of the gantry 2 and between the two guide rail grooves 7, a vision inspection camera 8 is fixedly installed. At the upper end of the gantry 2, an adjustment structure 3 is fixedly installed. The adjustment structure 3 is composed of a mounting plate 9, a lead screw 10 and a rotating column 11. There are two mounting plates 9. The lead screw 10 is rotatably installed on the two mounting plates 9. There are two rotating columns 11 and they are respectively fixedly installed at both ends of the lead screw 10. The mounting plate 9 on the adjustment structure 3 is fixedly installed at the upper end of the gantry 2. The two rotating columns 11 are respectively located outside the two mounting plates 9. Two connecting brackets 4 are symmetrically installed on the lead screw 10. The connecting bracket 4 is composed of a mounting block 12, an L-shaped plate 13 and a base plate 14. The L-shaped plate 13 is fixedly installed at the lower end of the mounting block 12. The base plate 14 is fixedly installed at the inner end of the L-shaped plate 13. The mounting block 12 on the connecting bracket 4 is located at the upper end of the gantry 2, and a threaded hole 15 is opened on the mounting block 12. The mounting block 12 is installed on the lead screw 10 through the threaded hole 15. The L-shaped plate 13 passes through the guide rail groove 7 downward. The base plate 14 is located inside the gantry 2, and a number of square holes 16 are evenly opened on the base plate 14. A number of pressing and fixing structures 5 are movably installed on the base plate 14. The pressing and fixing structure 5 is composed of a square rod 17, a spring 18, a baffle 19, a base block 20, a mounting shaft 22 and a pressing roller 23. The spring 18 is sleeved on the square rod 17. The baffle 19 is fixedly installed at the upper end of the square rod 17. The base block 20 is fixedly installed at the lower end of the square rod 17. The mounting shaft 22 is rotatably installed in the base block 20. The pressing roller 23 is fixedly installed at the inner end of the mounting shaft 22, and the pressing roller 23 is located inside the mounting shaft 22 at the same time. The square rod 17 is movably installed in the square hole 16. The spring 18 is located below the base plate 14. The baffle 19 is located above the base plate 14. An installation groove 21 is opened on the base block 20. The mounting shaft 22 is rotatably installed in the installation groove 21. The pressing roller 23 can be in contact with the conveyor belt 6. By setting the connecting bracket 4 and the pressing and fixing structure 5 and making them cooperate with each other, under the elastic force of the spring 18, the pressing roller 23 will tightly press the solar cell on the conveyor belt 6, which not only realizes the fixation of the solar cell, but also will not clamp and bend the solar cell, so that the solar cell can be effectively and quickly detected.

[0021] It should be noted that the present utility model is a detector for defects of solar photovoltaic module cells. When in use, the solar cells to be detected can be placed on the working conveyor belt 6. At the same time, the solar cells are positioned below the two rows of pressing and fixing structures 5, that is, the solar cells are pressed and fixed on the conveyor belt 6 by the pressing rollers 23. At this time, as the conveyor belt 6 conveys the solar cells backward, the pressing rollers 23 will also rotate. When the solar cells pass below the vision detection camera 8, the vision detection camera 8 will capture video images of the solar cells and transmit the captured video images to the terminal device. The staff will compare them with the image information of qualified solar cells to detect the defects of the solar cells. When it is necessary to adjust the distance between the two connecting brackets 4 according to the size of the solar cells so that the pressing rollers 23 on the pressing and fixing structure 5 can accurately press on the solar cells to fix the solar cells, the lead screw 10 on the adjusting structure 3 can be rotated. As a result, the lead screw 10 will drive the connecting brackets 4 to approach or move away from each other. At this time, the connecting brackets 4 will drive the pressing and fixing structure 5 to move. When the distance between the two groups of pressing and fixing structures 5 matches the size of the solar cells, stop rotating the lead screw 10.
