[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 6 The present invention provides an umbrella frame driving mechanism of an optical coating machine, including a rotating disk 4 and a lifting disk 5. The rotating disk 4 is connected to a motor 2 for driving the rotating disk 4 to rotate. The rotating disk 4 is connected to a clamping mechanism for clamping the umbrella frame, and the clamping mechanism includes a plurality of L-shaped pressure plates 25, a plurality of springs 28, and a plurality of L-shaped push plates 26. There are three L-shaped pressure plates 25, and the adjacent angles are 120°. There are also three corresponding springs 28 and L-shaped push plates 26. The L-shaped pressure plate 25 is movably connected to the rotating disk 4. The spring 28 is used to drive the L-shaped pressure plate 25 to move in a direction close to the L-shaped push plate 26. The L-shaped push plate 26 is connected to the side of the L-shaped pressure plate 25. The lifting disk 5 is used to drive the L-shaped push plate 26 to move forward, and the lifting disk 5 is connected to a cylinder 3 for driving the lifting disk 5 to move up and down. The lifting plate 5 is connected to a holding mechanism for keeping the umbrella stand rotating stably, and the holding mechanism includes a connecting rod 11, a moving block 12, an inclined groove 13, a driving seat 14, and a V-shaped plate 16. Both ends of the connecting rod 11 are connected to the lifting plate 5 and the moving block 12. The moving block 12 is slidably connected to the inclined groove 13. The inclined groove 13 is arranged on the driving seat 14. The V-shaped plate 16 is connected to the end of the driving seat 14. The driving seat 14 is connected to a guide mechanism for guiding the driving seat 14.

[0020] When in use, the connector 24 at the top of the umbrella stand is attached to the rotating disk 4. At this time, the L-shaped pressure plate 25 is aligned with the groove 23. The three cylinders 3 drive the lifting disk 5 to move downward, and the pressing surface 22 presses on the top of the L-shaped push plate 26. The two slide relative to each other, thereby driving the L-shaped push plate 26 and the L-shaped pressure plate 25 to move forward, and the spring 28 is gradually compressed until the L-shaped pressure plate 25 is pressed against the groove 23, thereby clamping and fixing the umbrella stand. At the same time, the downward movement of the lifting disk 5 can drive the two connecting rods 11 to move downward, so that the moving block 12 slides in the inclined groove 13, and can drive the driving seat 14 and the V-shaped plate 16 to move forward. The V-shaped plate 16 is clamped on the support ring 7 of the umbrella stand, thereby supporting and limiting the umbrella stand, improving the stability of the umbrella stand rotation, and facilitating the lens coating operation.

[0021] When the umbrella stand is driven to rotate, the motor 2 drives the rotating disk 4 to rotate, thereby realizing the rotation of the L-shaped pressing plate 25 and the L-shaped pushing plate 26, so that the end of the L-shaped pushing plate 26 slides on the pressing surface 22, and the umbrella stand can be rotated.

[0022] When the coating is completed, the motor 2 stops the rotating disk 4, and the umbrella stand stops rotating. Then the three cylinders 3 drive the lifting disk 5 to move upward, and the compressed spring 28 drives the L-shaped pressure plate 25 to move back, so that the L-shaped pressure plate 25 is separated from the groove 23, and the umbrella stand is loosened. At the same time, the upward movement of the lifting disk 5 can drive the two connecting rods 11 to move upward, so that the moving block 12 moves back in the inclined groove 13, and can drive the driving seat 14 and the V-shaped plate 16 to move backward. The V-shaped plate 16 is separated from the support ring 7 of the umbrella stand, which does not provide support and limit for the umbrella stand, and reserves space for taking out the umbrella stand. The operation is simple and convenient, and the flexibility is high.

[0023] The clamping mechanism further includes a plurality of guide posts 27 and a plurality of slide grooves 29. The slide grooves 29 are arranged at the bottom of the rotating disk 4. The L-shaped pressing plate 25 is slidably connected to the slide grooves 29. The guide posts 27 are connected in the slide grooves 29, and the guide posts 27 pass through the L-shaped pressing plate 25. The coordinated use of the guide posts 27 and the slide grooves 29 enables the L-shaped pressing plate 25 to reciprocate stably, thus achieving a good guiding purpose.

[0024] The second spring 28 is sleeved on the guide pillar 27 , and the two ends of the second spring 28 are connected to the L-shaped pressing plate 25 and the rotating disk 4 .

[0025] A pressing surface 22 is provided at the bottom of the side of the lifting plate 5 , and the pressing surface 22 is connected to the end of the L-shaped push plate 26 . The pressing surface 22 is a smooth surface, which can reduce the contact friction with the L-shaped push plate 26 .

[0026] The holding mechanism further includes a plurality of rolling balls 17 and a clamping groove 18. The clamping groove 18 is arranged on the side of the V-shaped plate 16, and the plurality of rolling balls 17 are rotatably connected to the inner side of the clamping groove 18. When the clamping groove 18 is clamped on the support ring 7, the rolling balls 17 are connected to the inclined surface 19 of the support ring 7, and the two are in rolling friction, thereby reducing the wear on the support ring 7.

[0027] The guide mechanism includes a fixed cylinder 8, a connecting column 15, a sliding block 20, and a spring 21. The fixed cylinder 8 is fixed to the coating box 1. The two ends of the connecting column 15 are connected to the sliding block 20 and the driving seat 14. The sliding block 20 is slidably connected in the fixed cylinder 8. The spring 21 is sleeved on the connecting column 15, and the two ends of the spring 21 are connected to the sliding block 20 and the fixed cylinder 8. When the driving seat 14 and the V-shaped plate 16 reciprocate, the connecting column 15 and the sliding block 20 can be synchronously driven to move, which plays a good guiding role for the V-shaped plate 16, so that the V-shaped plate 16 is accurately clamped on the supporting ring 7.

[0028] A vertical groove 10 is provided on the inner side of the coating box 1, and a guide block 9 is slidably connected to the vertical groove 10. The guide block 9 is fixedly connected to the connecting rod 11. When the connecting rod 11 is lifted or lowered, the guide block 9 slides in the vertical groove 10, which can improve the lifting stability of the connecting rod 11.

[0029] Three cylinders 3 are provided, and adjacent angles are equal. The cylinders 3 and the motor 2 are connected to the top of the coating box 1 . The power output end of the motor 2 is connected to the rotating disk 4 , and the power output end of the cylinder 3 is connected to the lifting disk 5 .

[0030] An operating method of an umbrella frame driving mechanism of an optical coating machine comprises the following steps: Step 1: The connector 24 at the top of the umbrella stand contacts the rotating disk 4, and the cylinder 3 drives the lifting disk 5 to move downward. The lifting disk 5 applies a thrust to the L-shaped push plate 26, so that the three L-shaped pressure plates 25 move synchronously toward the center direction of the rotating disk 4. At this time, the spring 28 is gradually compressed, and the three L-shaped pressure plates 25 are clamped on the connector 24 to clamp and fix the umbrella stand; Step 2: When the lifting plate 5 moves downward, the two connecting rods 11 are synchronously driven downward, so that the moving block 12 slides in the inclined groove 13, driving the three driving seats 14 to move synchronously, so that the three V-shaped plates 16 are connected to the supporting ring 7 of the umbrella frame, ensuring the stability of the umbrella frame rotation, and also supporting the umbrella frame, which is beneficial to the coating operation. At this time, the spring 1 21 is in a compressed state; Step 3: After the coating is completed, the cylinder 3 drives the lifting plate 5 to move upward, and the compressed spring 28 drives the L-shaped pressure plate 25 to return to its original position, so that the L-shaped pressure plate 25 is separated from the connecting head 24, thereby loosening the umbrella frame. At the same time, the two connecting rods 11 also move upward, so that the moving block 12 moves back in the inclined groove 13, driving the three driving seats 14 to move back synchronously, that is, the three V-shaped plates 16 are separated from the supporting ring 7 of the umbrella frame, leaving space for taking out the umbrella frame, which is highly practical.
