After the first side detection device 210 on the first transmission device 200 acquires the size of the plate, the slide driver 620 drives the movement detection component 630 to move to a designated position along the side detection slide 610 . At this time, the left 2D camera and the left 3D camera mounted on the movement detection component 630 , and the field of view of the left light source match the side of the board. The plate is always transported to the right by the inclined roller group 710, and the fixed detection component 640 formed by the right 2D camera, the right 3D camera and the right light source can be fixed on the right side for detection. The plate enters the turning transmission device 300, and the roller of the roller assembly 320 is driven by the roller driver 340 to roll, so that the plate continues to move forward. When the photoelectric sensor is covered, the roller driver 340 stops, and the transfer lifting driver 360 drives the transfer and transmission The component 330 rises, and the transfer and transmission driver 350 drives the transfer and transmission component 330 to rotate, so that the board starts to move laterally, and the other two sides of the board are detected by the second side detection device 510 .

For traditional manual inspection, manual inspection can only conduct random inspection on the production line production plate, and can only be inspected after the plate production is completed. The overall detection efficiency of the board structure online defect detection system described in this embodiment is improved and the workload is reduced.

For traditional visual inspection equipment, it can only be installed at a fixed height and distance to detect the front and back of the board. The plate structure online defect detection system described in this embodiment can detect the side of the plate through the rapid and precise movement of the side detection slide 610, meeting the needs of plate manufacturers for six-sided inspection of the plate.

For example, the side detection sliding table 610 is driven by the sliding table driver 620 (such as a servo motor), and the moving speed can be 1200 mm/s. Based on the maximum plate width of 1200 mm and the minimum plate width of 100 mm, the actual running distance of the moving detection component 630 is 1100 mm. , the running time is 1 second to 1.5 seconds; calculated according to the maximum plate length running distance of 2450mm, the running time is 2 seconds to 2.5 seconds. The distance for the plate to move to the left and right detection stations after passing through the code scanning device 800 is about 3000mm, and the equipment runs at a speed of 750mm/s, and about 4 seconds can be reserved to meet the requirements of the side detection slide 610. The overall equipment speed of the board structure online defect detection system described in this embodiment can be matched with the production line speed to meet the online production efficiency.
