Because the moving belt 202 is thin and there are three of them, when driving the object to move, it does not affect the line of sight of the camera 4 and can also provide stable support for the bottom of the object.

[0035] The working principle of this utility model is:

[0036] First, the air pump is driven to allow the gas to enter the interior of the sliding shell 707 through the telescopic hose, and then pass through the through slot 708 into the interior of the gas transmission pipe 705 to inflate an airbag 702. When a group of airbags 702 are inflated, the sliding block 701 is pushed to slide downward in the inner cavity of the slide groove 704. During the sliding, the flip plate 5 is driven to flip around the spherical rod 502 through the bearing. Then, the object to be inspected is placed on the top of the moving belt 202. When the moving belt 202 drives the object to move in the inner cavity of the shell 1 toward the end of the flip plate 5, the motor is driven to cause its output shaft to drive the gear 302 to rotate, so that the gear 302 drives the tooth block 301 to drive the connecting shell 3 to rotate. When the connecting shell 3 drives the camera 4 to rotate, the outer surface of the object is inspected.

[0037] When the object passes the inspection, the moving belt 202 drives the object to the top of the flip plate 5, and then follows the tilt direction of the top of the flip plate 5 to roll toward the top of a group of conveyor belts 6, and moves to one side through the conveyor belts 6 for easy collection;

[0038] When the object fails the inspection, the motor needs to be driven to drive the threaded rod 709 to rotate. When the threaded rod 709 rotates, the sliding shell 707 is driven to slide on the outer wall of the gas transmission pipe 705, so that the sliding shell 707 slides to the outside of another set of through grooves 708, and the air pump is driven again to allow the gas to enter the sliding shell 707 through the telescopic hose, and then pass through the through grooves 708 into the gas transmission pipe 705, inflating another air bag 702. When the air bag 702 bulges, it pushes the sliding block 701 to slide downward in the inner cavity of the slide groove 704, and when sliding, it drives the flip plate 5 to flip to the other side around the spherical rod 502 through the bearing, so that the moving belt 202 drives the object to move to the top of the flip plate 5, and then follows the inclined direction of the top of the flip plate 5 to roll to the top of another set of conveyor belts 6, and moves to one side through the conveyor belt 6 for collection, repair or destruction.

Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
