When the lifting frame 14 is extended, the rotating member 4 is driven to contact the limiting frame 43, so that the first support frame 111 can be turned counterclockwise by 90 degrees, so as to avoid the umbrella frame 110 from colliding with the first support frame 111 when being removed, so that the staff can more conveniently take out the umbrella frame 110 from the lifting frame 14.

[0046] The complete working principle and steps of the above embodiment are as follows:

[0047] refer to Figures 1 to 4 As shown, when the coating device is in the initial state, the rotating frame 11 and the servo motor 17 are both in the off state, the multi-stage telescopic member 12 is threadedly connected to the bottom of the outer surface of the rotating screw 13, and the limiting screw 16 has not been rotated and inserted into the threaded hole on the outer surface of the limiting member 15;

[0048] When the device is used to coat the optical lens, the umbrella stand 110 with the optical lens is first placed on the upper surface of the rotating member 19, and then the servo motor 17 is started. As the output shaft of the servo motor 17 rotates, the rotating screw 13 at the bottom of the output shaft of the servo motor 17 is driven to rotate simultaneously, and the outer surface of the bottom of the rotating screw 13 is threadedly connected to the rear side of the multi-stage telescopic member 12. When the rotating screw 13 rotates, the multi-stage telescopic member 12 is driven to move upward. When the multi-stage telescopic member 12 moves upward, it drives the lifting frame 14 fixedly connected to the output shaft of the multi-stage telescopic member 12 to move simultaneously, and the lifting frame 14 is away from the multi-stage telescopic member 12. 2 is fixedly connected to another multi-stage telescopic member 12, and when the lifting frame 14 moves upward, it will drive another lifting frame 14 to move upward at the same time on the inner side of the coating machine 1, and when the lifting frame 14 moves upward, it will drive the rotating member 19 connected to the upper surface of the lifting frame 14 to move simultaneously, and when the rotating member 19 moves upward, it will drive the first support frame 111 connected to the outer surface of the rotating member 19 and the second support frame 112 fixedly connected to the outer surface of the rotating member 19 to move simultaneously, and the rotating member 19 will also drive the umbrella frame 110 on the upper surface to move simultaneously, so that the lifting and lowering process of the umbrella frame 110 can be controlled , and accurately installing the umbrella stand 110 can ensure that the position of the optical glass is accurate during the production process, avoiding position deviation caused by installation errors, and the height of the umbrella stand 110 moving upward will not exceed the height of the rotating frame 11. At this time, when the rotating member 19 drives the umbrella stand 110 to move to the bottom of the rotating frame 11, the first support frame 111 and the second support frame 112 will simultaneously drive the limiting screw 16 to move upward, and at this time, the rotating frame 11 is started, so that the rotating frame 11 can rotate slightly, and when the rotating frame 11 rotates slightly, it will drive the limiting member 15 to rotate at the same time, and after the limiting member 15 rotates, the threaded hole of the limiting member 15 is at When the bottom of the limiting screw rod 16 is in a vertical state, the servo motor 17 is started again at this time, so that the output shaft drives the rotating screw rod 13 to rotate in the opposite direction. When the rotating screw rod 13 rotates in the opposite direction, the multi-stage telescopic member 12 can drive the lifting frame 14 to move downward a short distance at the same time. When the lifting frame 14 moves downward, it will drive the first support frame 111 and the second support frame 112 to move simultaneously through the rotating member 19. As the first support frame 111 and the second support frame 112 move downward, they will drive the limiting screw rod 16 to move simultaneously, so that the bottom of the limiting screw rod 16 can be inserted into the threaded groove opened through the limiting member 15.

[0049] When the umbrella stand 110 is processed, the servo motor 17 will drive the rotating screw 13 to rotate in the opposite direction, causing the multi-stage telescopic part 12 to move upward on the outer surface of the rotating screw 13. As the multi-stage telescopic part 12 moves upward, the lifting frame 14 drives the rotating part 19 to move at the same time. When the rotating part 19 moves upward, it will drive the limiting screw 16 to move at the same time through the first support frame 111 and the second support frame 112, causing the limiting screw 16 to slide out of the threaded groove inside the limiting part 15. After the rotating frame 11 drives the limiting part 15 to rotate slightly in the opposite direction, the servo motor 17 rotates forward and indirectly drives the umbrella stand 110 to move downward.

[0050] refer to Figures 5 to 7 As shown, when the coating device is in the initial state, the limiting rod 2 has not yet rotated to insert into the inner side of the square groove of the moving member 22, and the outer surface of the bottom of the guide member 21 has not yet slid into the inner side of the square hole of the limiting block 23;

[0051] As the umbrella frame 110 moves to the bottom of the rotating frame 11, the rotating frame 11 is started, causing the rotating frame 11 to drive the limiting rod 2 to rotate slightly clockwise. When the limiting rod 2 rotates slightly, the outer surface of the limiting rod 2 will rotate and insert into the inner side of the square groove of the moving part 22, and the rotating frame 11 will drive the limiting part 15 and the guide part 21 fixedly connected to the outer surface of the limiting part 15 to rotate at the same time. At this time, the threaded groove opened in the limiting part 15 will be in a vertical state with the bottom of the limiting screw rod 16, and the bottom of the guide part 21 will also be in a vertical state with the bottom of the square hole of the limiting block 23. At this time, the limiting screw rod 16 will drive the limiting screw rod 16 to move simultaneously through the first support frame 111 and the second support frame 112. Since the inner side of the square groove of the moving part 22 is clamped on the outer surface of the limiting rod 2, as the limiting screw rod 16 moves downward, it will not drive the moving part 22 to move simultaneously. When the limiting screw rod 16 moves downward on the inner side of the moving part 22, the limiting screw rod 16 will be prompted to rotate. As the limiting screw rod 16 rotates and moves downward, it will be inserted into the threaded groove on the outer surface of the limiting part 15 and rotate downward. At this time, the outer surface of the bottom of the limiting screw rod 16 can be completely turned into the inner side of the limiting part 15, and the first support frame 111 and the second support frame 112 will also drive the limiting block 23 to move downward at the same time. As the limiting block 23 moves downward, the square hole of the limiting block 23 will slide into the outer surface of the bottom of the guide member 21, prompting the guide member 21 to clamp the limiting block 23, thereby automatically fixing the umbrella stand 110, reducing manual intervention before processing of optical lenses, speeding up production, and automatic fixation can ensure that the umbrella stand 110 maintains a stable position and posture during the processing, which helps to improve the surface flatness of the optical glass.

[0052] When the processing of the optical lens is completed, the outer surface of the limiting rod 2 still slides in the square groove inside the moving part 22, and the lifting frame 14 will drive the limiting screw 16 to move upward through the first support frame 111 and the second support frame 112. At this time, the limiting screw 16 will rotate in the opposite direction on the inner side of the moving part 22. As the limiting screw 16 rotates in the opposite direction, the outer surface of the bottom of the limiting screw 16 will slide out of the threaded groove of the limiting part 15, and the first support frame 111 and the second support frame 112 will also drive the limiting block 23 to move at the same time when moving upward, causing the limiting block 23 to slide out from the outer surface of the bottom of the guide member 21 and disengage from the clamping connection with the limiting block 23. At this time, the rotating frame 11 drives the limiting rod 2 and the limiting member 15 to rotate counterclockwise. As the limiting rod 2 rotates counterclockwise, it will slide out of the square groove of the moving member 22. At this time, the lifting frame 14 can drive the umbrella frame 110 to move downward.

[0053] refer to Figure 8 and Fig. 9 As shown, when the coating device is in the initial state, the multi-stage telescopic member 12 is in a contracted state, the bottom of the support block 31 is slidably connected to the rear side of the upper surface of the wedge-shaped frame 3, and the return spring 34 is in a naturally relaxed state;

[0054] As the umbrella stand 110 is processed, the lifting frame 14 will drive the umbrella stand 110 to move downward, and the lifting frame 14 will drive the support block 31 fixedly connected to the bottom of the lifting frame 14 to move at the same time when moving downward. Since the lower surface of the support block 31 is pressed and matched with the upper surface of the wedge frame 3, as the support block 31 moves downward, it will slide forward on the upper surface of the wedge frame 3, and when the support block 31 slides forward, it will drive the lifting frame 14 to move forward at the same time, and when the lifting frame 14 moves forward, it will drive the output end of the multi-stage telescopic member 12 to extend outward. The upper surface of the output end of the multi-stage telescopic member 12 is fixedly connected to the bottom of the first connecting block 32. As the output end of the multi-stage telescopic member 12 slides forward, the first connecting block 32 will be driven to move forward at the same time. When the first connecting block 32 moves forward, the reset spring 34 will be moved to a stretched state. At this time, the lifting frame 14 can smoothly remove the umbrella frame 110 from the interior of the coating machine 1 by limiting the screw rod 16, avoiding the collision of the umbrella frame 110 with the inner wall of the coating machine 1 due to manual operation by the staff, and can also facilitate the staff to replace the umbrella frame 110.

[0055] When the new umbrella frame 110 is replaced on the upper surface of the limiting screw rod 16, the rotating screw rod 13 drives the lifting frame 14 to move upward through the multi-stage telescopic part 12, and the lifting frame 14 will drive the support block 31 to move upward at the same time. At this time, the bottom of the support block 31 will be separated from the upper surface of the wedge frame 3, and the return spring 34 in the stretched state will drive the multi-stage telescopic part 12 to retract backward through the first connecting block 32. As the multi-stage telescopic part 12 retracts backward, it will drive the lifting frame 14 to move backward at the same time. At this time, the lifting frame 14 will drive the umbrella frame 110 back to the inner side of the coating machine 1 through the limiting screw rod 16.

[0056] refer to Fig.10 and Fig.11 As shown, when the coating device is in the initial state, the first support frame 111 and the upper surface of the rotating member 19 are in a vertical state, the outer surface of the rotating member 4 has not yet been attached to the outer surface of the limiting frame 43, and the reset torsion spring 42 is in a naturally relaxed state;

[0057] When the umbrella stand 110 is processed, the lifting frame 14 will drive the umbrella stand 110 to slide forward through the rotating member 19, and the rotating member 4 is slidably connected in the arc groove of the rotating member 19. As the rotating member 19 slides forward, it will drive the rotating member 4 to slide at the same time, and the rotating member 4 will fit the outer surface of the limiting frame 43 when it slides forward. At this time, the rotating member 19 drives the rotating member 4 to continue to slide forward, and the rotating member 4 will be blocked by the limiting frame 43. At this time, the rotating member 4 will slide to the left inside the arc groove of the rotating member 19, and as the rotating member 4 slides to the left, it will drive the connecting rope 41 fixedly connected to the right side of the rotating member 4 to move at the same time Since the end of the connecting rope 41 away from the rotating member 4 is fixedly connected to the inner side of the first support frame 111, as the rotating member 4 drives the connecting rope 41 to slide at the same time, the first support frame 111 will be prompted to rotate forward ninety degrees, and the left side of the first support frame 111 is fixedly sleeved on the right end of the reset torsion spring 42. As the first support frame 111 rotates forward ninety degrees, the reset torsion spring 42 will rotate to a force storage state. At this time, after the first support frame 111 rotates downward, the staff can more conveniently remove the umbrella frame 110 from the rotating member 19, thereby avoiding the umbrella frame 110 from colliding with the first support frame 111 when being removed.

[0058] At this time, the new umbrella stand 110 is installed on the upper surface of the rotating member 19, and the lifting frame 14 will drive the rotating member 19 and the umbrella stand 110 to move backward, and the rotating member 19 will drive the rotating member 4 to move at the same time when it moves backward. As the rotating member 4 moves backward, it will break away from the fit with the outer surface of the limiting frame 43, and the reset torsion spring 42 in the power storage state will drive the first support frame 111 to rotate backward ninety degrees for reset. As the first support frame 111 rotates backward ninety degrees, the connecting rope 41 will also be wrapped back to the outer surface on the left side of the bottom of the first support frame 111. As the connecting rope 41 returns to the outer surface on the left side of the bottom of the first support frame 111, the end of the connecting rope 41 away from the first support frame 111 will drive the rotating member 4 to slide back to the initial state.
