Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a defect detection device for solar panels. Background Art

[0002] A solar panel is a device that absorbs sunlight and directly or indirectly converts solar radiant energy into electrical energy through the photovoltaic effect or the photochemical effect. During the production and processing of solar panels, sometimes the surface defects of the produced solar panels are very likely to affect the product quality. Therefore, it is very necessary to detect defects of different sizes on the surface of solar panels, and such a defect detection device for solar panel surfaces is required. This device uses a camera to take pictures of the surface of the solar panel and transmits the taken pictures to a terminal device, and the staff checks the picture information of the solar panel to detect the defects of the solar panel.

[0003] However, when people use the defect detection device for solar panel surfaces, if a large number of solar panels need to be detected, due to the different specifications and placement positions of each solar panel every time, the shooting parameter information of the camera is also different, and corresponding adjustments need to be made by the staff. When the staff detects a large number of solar panels, if they continuously adjust the parameter information of the camera, it is time-consuming and laborious. Summary of the Utility Model

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The solar panel is abutted against the positioning frame, and through the expansion and contraction of the telescopic spring, the two pushing blocks are abutted against the outer walls on both sides of the solar panel, so as to ensure that solar panels of different specifications can be located on the center line of the bottom plate, ensuring the consistency of the placement positions of the solar panels. When performing detection, the servo motor drives the first lead screw to rotate. The rotating first lead screw drives another first lead screw to rotate through the belt pulley connected by transmission. The rotating first lead screw drives the screwed moving block to move along the fixed frame, so that the ultrasonic detection head moves up and down along the solar panel for detection. The ultrasonic detection head transmits the detection result to the controller. When the detection result is unqualified, the controller gives an alarm.

[0008] Preferably, a controller is installed on the outer wall of one side of the bottom plate, and the controller is electrically connected to the ultrasonic detection head.

[0009] The ultrasonic detection head transmits the detection result to the controller. When the detection result is unqualified, the controller gives an alarm.

[0010] Preferably, through holes are formed in the outer walls at both ends of the positioning frame, and the through holes form a sliding fit with the connecting rod, and the pushing block forms a sliding fit with the positioning frame.

[0011] By abutting the solar panel against the positioning frame and through the expansion and contraction of the telescopic spring, the two pushing blocks are abutted against the outer walls on both sides of the solar panel, so as to ensure that solar panels of different specifications can be located on the center line of the bottom plate, ensuring the consistency of the placement positions of the solar panels.

[0012] Preferably, a servo motor is installed on the outer wall of one end of one of the fixed frames, and the output shaft of the servo motor is fixedly connected to one end of the first lead screw.

[0013] The servo motor drives the first lead screw to rotate.

[0014] Preferably, belt pulleys are sleeved and fixed at the other ends of the two first lead screws, and the two belt pulleys are connected by belt transmission.

[0016] Preferably, the moving block is screwed to the first lead screw, and the moving block forms a sliding fit with the fixed frame, and the adjusting block forms a sliding fit with the connecting frame.

[0017] The rotating first lead screw drives the screwed moving block to move along the fixed frame, so that the ultrasonic detection head moves up and down along the solar panel for detection.

[0018] The beneficial effects of the present utility model are:

[0019] By abutting the solar panel against the positioning frame and making the two push blocks abut against the outer walls on both sides of the solar panel through the expansion and contraction of the telescopic spring, it is ensured that solar panels of different specifications can be located on the center line of the bottom plate, ensuring the consistency of the placement positions of the solar panels. During detection, the servo motor drives the movable block to move along the fixed frame through the first lead screw, so that the ultrasonic detection head moves up and down along the solar panel for detection. The ultrasonic detection head transmits the detection result to the controller. When the detection result is unqualified, the controller gives an alarm, effectively solving the problem in the prior art that due to the different specifications and placement positions of the solar panels each time, the shooting parameter information of the camera also varies, and it takes time and effort for the staff to make corresponding adjustments.
