[0021] Several scanning detection probes 34 are provided at the top and bottom of the inner side of the detection cover 25, and several lighting strips 35 are provided at the top and bottom of the inner side of the detection cover 25. The scanning detection probes 34 can obtain images of the surface of the photovoltaic panel when inspecting the photovoltaic panel, and then analyze and identify the type and location of the defects through the image processing system in the external computer. The lighting strips 35 can illuminate the surface of the photovoltaic panel, thereby improving the accuracy of photovoltaic panel inspection.

[0023] In summary, when the photovoltaic panel defect detection device is in use, the photovoltaic panel to be inspected is transported to the electric roller 18 through the feeding conveyor belt 2 and is limited by the limit plate 13. Then the controller in the control box controls the electric telescopic rod 15 to retract, so that the photovoltaic panel can fall to the inside of the through slot 11 in the placement frame 10, and the photovoltaic panel is supported by the support plate 12. Then, the controller in the control box controls the stepper motor 7 to start driving the driving gear 8 to rotate. After the driving gear 8 engages with the driven gear 6, it drives the mounting shaft 4 and the turntable 5 to rotate 90°, and then the photovoltaic panel in the through slot 11 is rotated to the inside of the first side groove 22. Then the control box turns on the negative pressure fan 30 to discharge the air in the dust box 27, so that the dust suction port 33 generates suction, and the dust on the top and bottom surfaces of the photovoltaic panel inside the first side groove 22 can be sucked away and discharged into the dust box 27 through the dust suction pipe 31 and collected by the collection box 28. After the dust removal is completed, the control box controls the stepper motor 7 to start and drive the turntable 5 to rotate another 90° so that the placement frame 10 and the photovoltaic panel after dust removal are rotated to the inside of the second side groove 26, and then the scanning detection probe 34 is used to scan the surface of the photovoltaic panel to obtain an image. Finally, the image processing system in the external computer analyzes and identifies the type and location of the defect to complete the inspection. After the inspection is completed, the stepper motor 7 is controlled to start and drive the turntable 5 to rotate another 90° so that the placement frame 10 and the inspected photovoltaic panel are rotated to one side of the unloading conveyor belt 3. Then the control box controls the electric telescopic rod 15 at the bottom thereof to start and push the concave frame 16 and the electric roller 18 to move upward. The electric roller 18 pushes the photovoltaic panel out of the through groove 11 to one side of the unloading conveyor belt 3. After that, the electric roller 18 is turned on to convey the photovoltaic panel after inspection to the unloading conveyor belt 3 for unloading, and the operation is completed. During the inspection, after the photovoltaic panel is loaded into the inner side of a placement frame 10 and driven by the turntable 5 to rotate 90° to the first side groove 22 for dust removal, the loading conveyor belt 2 can then transport another photovoltaic panel to be inspected to the placement frame 10 moved to its side for placement. Then, when the dust removal of the first photovoltaic panel is completed, the turntable 5 is driven to rotate 90° and move to the inside of the second side groove 26 for inspection. Another photovoltaic panel is rotated to the first side groove 22 for dust removal. At the same time, there is still a placement frame 10 rotated to one side of the loading conveyor belt 2 for photovoltaic panel loading, until the first placement frame 10 is inspected in the second side groove 26. The turntable 5 is rotated 90° to the side of the unloading conveyor belt 3 for unloading. This reciprocating process can quickly and simultaneously perform loading, dust removal, inspection and unloading operations on multiple photovoltaic panels, with high efficiency.
