[0014] Compared with the prior art, an optical lens defect automatic detection device using the above technical solution has the following beneficial effects:

[0015] 1. When inspecting the thickness of the optical lens, the staff will first pour the optical lens on the top surface of the conveyor belt, and then the conveyor belt in the working state will drive the optical lens to move and transport. When the optical lens moves to the bottom of the fixed plate, the optical lens with qualified thickness will pass through the gap between the first winding belt and the conveyor belt, while the optical lens with unqualified thickness and too thick will contact the surface of the first winding belt. The first winding belt will rotate driven by the output shaft of the first motor, and during the rotation, it will drive the over-thick optical lens that is in contact with the first winding belt to move, so that it can be moved from the discharge slot to the inside of the installation slot, and then the optical lens with thickness defects can be identified autonomously, which increases the accuracy of the inspection results;

[0016] 2. Before inspecting the optical lens, the staff will first put different numbers of washers on the threaded column according to the specifications of the thickness of the optical lens to be inspected, so as to adjust the height of the fixing plate in the fixing groove, and then turn the nut on the surface of the threaded column so that the nut presses the fixing plate downward, so as to fix the fixing plate at the current height. By adjusting the number of washers, the height of the first winding belt can be adjusted, so that optical lenses of different specifications can be inspected, which increases the scope of application in inspecting optical lenses;

[0017] 3. After the staff places the optical lens to be inspected on the conveyor belt, the conveyor belt will work and drive the optical lens close to the second winding belt. At this time, the second motor in the working state will use the rotating output shaft to drive the second winding belt to rotate, so as to guide the optical lens to move one by one between the two mounting plates. According to the diameter of the optical lens, the staff will adjust the spacing between the two mounting plates. The staff will first unscrew the fixing bolt from the thread groove, and then apply a lateral force to the mounting plate to make the mounting plate slide in the sliding opening and drive the sliding rod to slide synchronously inside the limit opening. After adjusting to the diameter of the corresponding optical lens, the staff will screw the fixing bolt into the thread groove again to fix the position between the two mounting plates, so as to ensure that the optical lenses can be arranged in a straight line on the conveyor belt when conveying them, so as to facilitate the inspection in sequence.

[0018] 4. When the conveyor belt drives the optical lens to move, the PLC controller will control the third motor to work periodically, so that the rotating plate rotates periodically, and the two rotating plates are periodically spliced ​​or separated from each other, so that the distance between the two optical lenses on the conveyor belt can be kept consistent, avoiding the two optical lenses from interfering with each other's inspection due to being too close, thereby increasing the accuracy of the inspection results;

[0019] 5. Before inspecting the optical lenses, the staff will first push the storage frame to move under the installation slot. After moving, the storage frame will enter the inside of the fixed folding plate and drive the handle to enter the inside of the limit slot, which can prevent the storage frame from shaking inside the fixed folding plate. At the same time, the defective optical lenses discharged from the discharge slot will fall back into the storage frame, so that the defective optical lenses can be recovered and distinguished.

At this time, the second motor 23 in the working state will use the rotating output shaft to drive the second winding belt 24 to rotate, thereby guiding the optical lenses to move one by one between the two mounting plates 19. According to the diameter of the optical lens, the staff will adjust the spacing between the two mounting plates 19. The staff will first unscrew the fixing bolt 30 from the threaded groove 29, and then apply a lateral force to the mounting plate 19 to make the mounting plate 19 slide in the sliding opening 18 and drive the sliding rod 27 to slide synchronously inside the limit opening 26. After adjusting to the diameter of the corresponding optical lens, the staff will screw the fixing bolt 30 into the threaded groove 29 again to fix the position between the two mounting plates 19, thereby ensuring that the optical lenses can be arranged in a straight line on the conveyor belt 2 when conveying them, which is convenient for inspection in sequence.
