[0036] like Figures 1-5As shown, this embodiment provides a scratch detection and repair system for polished optical glass components, including a frame 29 and a control system. The control system controls all electronic components of this embodiment (e.g., cylinder 1, cylinder 6, cylinder 7, cylinder 4, motor 11, electromagnet lever 4, and electric push rod, etc.). The frame 29 includes a top plate 291 and leg plates 292. A process conversion device is installed on the top plate 291. The process conversion device has a material picking area A and a detection area B, and the process conversion device can move to the spray repair area C and the polishing repair area D. A placement bucket 21 is installed in the material picking area A, and the optical glass component to be tested is placed in the placement bucket 21. A motion device is installed on the process conversion device, and a negative pressure suction cup 6 is installed on the motion device. The negative pressure suction cup 6 can pick up or release the optical glass component to be tested, and the motion device drives... The dynamic negative pressure suction cup 6 moves to the material picking area A or the detection area B; a probe drive mechanism is installed on the frame 29, and an infrared flaw detection probe 8 is installed on the probe drive mechanism, which can detect the optical glass element to be tested in the detection area B; a spray repair device is installed on the frame 29, which sprays repair liquid onto the optical glass element to be tested in the spray repair area C; a grinding repair device is installed on the frame 29, which grinds and repairs the optical glass element to be tested in the grinding repair area D. The system of this embodiment can detect and repair a batch of optical glass elements. During the detection and repair process, no manual intervention is required. With the control system, fully automatic detection and repair can be achieved, although the efficiency of detection and repair is not high; the detected optical glass elements that need repair and those that do not need repair can be discharged separately; the optical glass elements that need repair can be sprayed and ground for repair.

[0037] like Figure 2 and Figure 3 As shown, the process conversion device includes a movable plate 20. The top of the frame 29 has a movable groove, within which the movable plate 20 can move. A motor 11 is installed at the bottom of the top plate 291 of the frame 29. A threaded rod 9 is rotatably installed inside the frame 29. The output end of the motor 11 is connected to the threaded rod 9, and the threaded rod 9 is threadedly connected to the movable plate 20. A guide post 10 is installed in the movable groove at the top of the frame 29. The movable plate 20 has a guide hole, which is fitted onto the guide post 10. When the motor 11 starts, the threaded rod 9 rotates under the drive of the motor 11, causing the movable plate 20 to move.

[0038] like Figure 2As shown, the rotation drive device includes a cylinder 1 mounted on the movable plate 20. A rack 2 is mounted on the piston rod of cylinder 1, and a spur gear 3 is mounted on the rotating shaft 18. The rack 2 meshes with the spur gear 3. The working process of the rotation drive device is as follows: When cylinder 1 is activated, the piston rod of cylinder 1 extends outward, and the rack 2 moves, causing the spur gear 3 to rotate counterclockwise. The rotation of the spur gear 3 causes the rotating shaft 18 to rotate counterclockwise, and the counterclockwise rotation of the rotating shaft 18 causes the mounting plate 19 to rotate counterclockwise. When the piston rod of cylinder 1 retracts inward, the rack 2 moves, causing the spur gear 3 to rotate clockwise. The rotation of the spur gear 3 causes the rotating shaft 18 to rotate clockwise, and the clockwise rotation of the rotating shaft 18 causes the mounting plate 19 to rotate clockwise. The movement drive device includes an electromagnet rod 4 connecting the bottom of the movable plate 20 and the mounting plate 19. When the electromagnet lever 4 is energized, it pushes the mounting plate 19 to move along the axis of the rotating shaft 18.

[0039] like Figure 1 and Figure 2 As shown, the placement bucket 21 includes a bucket wall and a support plate installed on the bottom inner side of the bucket wall. The bucket wall is mounted on a movable plate 20. A second cylinder 6 is installed at the bottom of the movable plate 20, and the piston rod of the second cylinder 6 is connected to the bottom of the support plate. Specifically, the second cylinder 6 is connected to the movable plate 20 via a second cylinder 6 bracket 22. After the optical glass element to be tested in the placement bucket 21 is grasped, the piston rod of the second cylinder 6 extends, driving the support plate in the placement bucket 21 to move upward, so that the optical glass element in the lower layer moves upward, thus facilitating the next grasp; the piston rod of the second cylinder 6 retracts, driving the support plate in the placement bucket 21 to move downward, and the support plate returns to the bottom position of the bucket wall.

[0040] like Figure 1 and Figure 2 As shown, the probe drive mechanism is mounted on a vertical plate on the frame 29. A cylinder 7 is mounted on the vertical plate, and a guide plate is mounted on the piston rod of the cylinder 7. An infrared flaw detection probe 8 is mounted on the guide plate. Vertically arranged guide protrusions 25 are provided on the vertical plate, and guide grooves are provided on the guide plate, with the guide protrusions 25 positioned within the guide grooves. When the cylinder 7 is activated, its piston rod extends, causing the guide plate to move downwards, which in turn moves the infrared flaw detection probe 8 downwards. When the piston rod retracts, the guide plate moves upwards, causing the infrared flaw detection probe 8 to move upwards. This embodiment of the probe drive mechanism allows for adjustment of the detection height, facilitating adjustment.

[0041] like Figure 4 and Figure 5As shown, the spray repair device includes an inverted U-shaped frame 12 mounted on a frame 29. A shower head 13 is installed on the top of the inner side of the inverted U-shaped frame 12, and the shower head 13 sprays repair fluid. Specifically, the shower head 13 is connected to a repair fluid tank via a pipe, and the repair fluid tank contains repair fluid. The shower head 13 sprays the repair fluid onto the surface of the optical glass element to be repaired.

[0042] like Figures 3-5 As shown, the grinding and repair device includes a grinding plate 17, on which a flexible material such as a lint-free cloth is placed. Drive rods 16 are installed at both ends of the grinding plate 17, and the drive rods 16 are movably mounted on an inverted U-shaped frame 12. A spring 15 and a limiting block 26 are sequentially installed on one of the drive rods 16, and the other drive rod 16 is connected to the output end of an electric actuator, which is mounted on the inverted U-shaped frame 12. When the electric actuator is activated, it extends outward or retracts inward, driving the grinding plate 17 to move back and forth via the drive rod 16 to grind the optical glass component to be repaired.

[0043] like Figure 5 As shown, a material discharge hole 27 is provided on the movable plate 20. A detection plate 28 is slidably mounted on the movable plate 20 at the material discharge hole 27. A cylinder 14 is mounted on the outside of the movable plate 20, and the piston rod of the cylinder 14 is connected to the detection plate 28. Specifically, a slide is provided on the movable plate 20 perpendicular to the material discharge hole 27, and the detection plate 28 is inserted into the slide. When the cylinder 14 is activated, the piston rod of the cylinder 14 extends outward, and the detection plate 28 moves outward along the slide. The detection plate 28 no longer blocks the material discharge hole 27, and the optical glass element on the detection plate 28 falls from the material discharge hole 27, completing the material discharge process. When the piston rod of the cylinder 14 retracts inward, the detection plate 28 moves inward along the slide, and the detection plate 28 blocks the material discharge hole 27. The optical glass element to be tested is located on the detection plate 28.

[0044] In this embodiment, cylinder 1, cylinder 6, cylinder 7, cylinder 4, motor 11, shower head 13, electromagnet pull rod 4, and electric push rod are all selected, and the infrared flaw detection probe 8 uses thermal imaging technology. All of these are within the scope of existing technology and will not be described in detail in this embodiment.

[0045] The working process of the scratch detection and repair system for polished optical glass components of this invention is as follows:

[0046] In the initial state, the piston rod of cylinder 26 retracts, the pallet returns to the bottom position of the barrel wall, and the optical glass element to be tested is placed in the barrel 21; the piston rod of cylinder 414 retracts inward, and the detection plate 28 blocks the material drop hole 27.

[0047] Material handling: Cylinder 1 is activated, and the piston rod of cylinder 1 extends outward or retracts inward. The rack 2 moves, driving the spur gear 3 to rotate. The rotation of the spur gear 3 drives the mounting plate 19 to rotate via the rotating shaft 18, moving the negative pressure suction cup 6 directly above the placement bucket 21 in the material handling area A. The electromagnet pull rod 4 is energized, and the electromagnet pull rod 4 pushes the mounting plate 19 downward along the axis of the rotating shaft 18, moving the negative pressure suction cup 6 to the top of the optical glass element to be tested. The negative pressure suction cup 6 is activated, and it sucks up the optical glass element to be tested.

[0048] When the material picking area A moves to the detection area B, the electromagnet pull rod 4 is energized. The electromagnet pull rod 4 pushes the mounting plate 19 to move upward along the axis of the rotating shaft 18. The cylinder 1 starts, the mounting plate 19 rotates, and the negative pressure suction cup 6 is moved to the top of the detection plate 28 in the detection area B.

[0049] During inspection, cylinder 3 (7) is activated, its piston rod extends, and the guide plate moves downward, causing the infrared flaw detector 8 to move downward. The infrared flaw detector 8 inspects the optical glass component to be inspected. After inspection, if the optical glass component is undamaged, cylinder 4 (14) is activated, its piston rod extends outward, and the inspection plate 28 no longer blocks the material drop hole 27. The optical glass component located on the inspection plate 28 falls from the material drop hole 27, completing the material drop process. If the optical glass component is damaged, it is sprayed and polished for repair before being dropped.

[0050] When the detection area B moves to the spraying and repair area C, the motor 11 starts and the threaded rod 9 rotates under the drive of the motor 11. The rotation of the threaded rod 9 drives the movable plate 20 to move and spray the repair area C.

[0051] Repair spraying: The shower head 13 sprays repair fluid onto the damaged optical glass element, and the repair spraying is completed.

[0052] The spray repair area C moves to the grinding repair area D, motor 11 starts, and the movable plate 20 continues to move, moving to the grinding repair area D;

[0053] Grinding and repair: The electric actuator is activated, and the electric actuator extends outward or retracts inward, driving the grinding plate 17 to move back and forth through the transmission rod 16 to grind the optical glass component to be repaired. Grinding and repair are completed.

[0054] Material feeding begins when cylinder 414 is activated. The piston rod of cylinder 414 extends outward, and the detection plate 28 no longer blocks the material feeding hole 27. The optical glass element located on the detection plate 28 falls from the material feeding hole 27, completing the material feeding process.

[0055] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. The protection scope of this utility model shall be determined by the protection scope of the claims.
