Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel detection, and in particular to an auxiliary fixing structure for photovoltaic panel detection. Background Art

[0002] The auxiliary fixing structure for photovoltaic panel inspection is a device used to keep the photovoltaic panel stable and safe during the inspection process. This structure usually includes a support frame, a clamping device and an adjustment mechanism. The support frame provides basic support for the entire structure. The clamping device is used to fix the photovoltaic panel to prevent it from moving or flipping during the inspection process. The adjustment mechanism allows the operator to adjust it according to the size and shape of the photovoltaic panel to ensure its correct position on the inspection equipment. This auxiliary fixing structure not only improves the accuracy of the inspection, but also ensures the safety of the operator.

[0003] After the photovoltaic panel is produced, it is necessary to conduct surface inspection to determine whether there are defects and flaws. If the inspection is conducted on a production line or a workbench, the back side is not easy to see and is not easy to turn over. In particular, for the comparison inspection of the front and back sides, including the later maintenance inspection, the back and forth flipping brings inconvenience to the inspection. Based on these problems, Chinese patent CN118809482A discloses an auxiliary fixing device for convenient clamping of photovoltaic panel inspection. Under the action of the second spring elastic force, the second spring pulls the connecting plate. Through the transmission of the connecting plate, the jackets on both sides of the photovoltaic panel can clamp the photovoltaic panel longitudinally. Under the action of the first spring elastic force, the U-shaped card plate and the jacket can clamp the photovoltaic panel horizontally. The handle is turned to drive the shaft rod to rotate, and the shaft rod drives the U-shaped card plate and the jacket to rotate, so that the angle of the photovoltaic panel between the U-shaped card plate and the jacket also changes. This fixing device has a simple structure, good stability of photovoltaic panel fixing, and good convenience of operation. The fixed photovoltaic panel is easy to adjust the angle, which effectively improves the efficiency of photovoltaic panel inspection.

[0004] When fixing the photovoltaic panels, the staff needs to adjust the distance and height between the two sets of L-shaped support beams and the moving direction of the clamps at both ends of the two sets of U-shaped pallets at the same time. If the heights of the two sets of L-shaped support beams are different or the combined lengths of the U-shaped pallets and the clamps are different, it will affect the normal installation and fixation of the photovoltaic panels, which will not only bring a lot of inconvenience to the work of the inspectors, but also hinder the normal progress of the photovoltaic panel inspection work.
