[0002] With the development of optical products, the application scope of optical lenses is getting wider and wider. Generally speaking, the manufactured optical lenses need to undergo subsequent processing to obtain good performance suitable for the application. The coating process is one of the important steps in the subsequent processing. Coating refers to the use of physical or chemical methods to coat a single layer or multiple layers of thin film on the surface of optical components, and use the interference effect of incident, reflected and transmitted light on the thin film interface to achieve focusing, collimation, filtering, reflection and refraction.

[0003] With the development of industry, in production and processing, the program-controlled movable frame will drive the material clamped by the claw arm to move in the X and Y axis directions.

[0019] 3. The present invention sets the U-shaped recessed structure of the end opening block in an inclined flared shape. After the vertical sleeve rod drives the movable penetration rod to reset away from the axis of the center mounting disk, when the end opening block moves away from the axis of the center mounting disk, the U-shaped flared inclined surface of the end opening block applies a thrust to the contacted retracted card block, thereby pushing the retracted card block into the movable penetration rod, so that the retracted card block can re-enter the U-shaped recessed structure of the end opening block for cooperation. When the end opening block moves close to the axis of the center mounting disk again, the end opening block can again synchronously drive the movable penetration rod and the lens clamping rod to move.

[0030] The following is combined with Figure 1-Figure 9 The present invention is described in further detail.

[0031] The embodiment of the present invention discloses a fully automatic lens coating machine. Figure 1-Figure 9 As shown, it includes a supporting main platform 1, and a transverse and longitudinal power control frame 2 is arranged above the supporting main platform 1. Both ends of the transverse and longitudinal power control frame 2 are fixed to the supporting main platform 1 through side frames 3. A power telescopic frame 4 is installed at the control end of the transverse and longitudinal power control frame 2. The program can change the transverse and longitudinal positions of the power telescopic frame 4 through the transverse and longitudinal power control frame 2. A vertical coaxial rod 6 is installed at the lower end of the power telescopic frame 4. A center mounting plate 5 is concentrically installed at the lower end of the vertical coaxial rod 6. The power telescopic frame 4 is extended and retracted under the control of a hydraulic cylinder and an electric telescopic rod, thereby driving the vertical coaxial rod 6 to move up and down, thereby changing the height of the center mounting plate 5.

[0032] The upper surface of the center mounting plate 5 is provided with a plurality of fixed-distance sliding grooves 7, and a vertical sleeve rod 8 is slidably inserted inside the fixed-distance sliding grooves 7. The vertical sleeve rod 8 is elastically connected to the center mounting plate 5 on one side of the fixed-distance sliding grooves 7 away from the axis of the center mounting plate 5. A horizontal tension telescopic rod 81 is fixed to the side of the vertical sleeve rod 8 away from the axis of the center mounting plate 5. The other end of the horizontal tension telescopic rod 81 is fixed to the center mounting plate 5. The horizontal tension telescopic rod 81 has a tendency to pull the vertical sleeve rod 8 away from the axis of the center mounting plate 5. The end of the vertical sleeve rod 8 located below the center mounting plate 5 is fixedly sleeved with a bottom inner groove frame 9. The bottom inner groove A lens clamp rod 10 is slidably inserted into the interior of the frame 9, and a side of the lens clamp rod 10 away from the axis of the center mounting disk 5 is elastically connected to the bottom inner groove frame 9. The lens clamp rod 10 and the bottom inner groove frame 9 have a tendency to approach the axis of the center mounting disk 5 under the elasticity, and the axis of the lens clamp rod 10 is arranged parallel to the axis of the center mounting disk 5. A double-rod slide 101 is fixed to a side of one end of the lens clamp rod 10 located inside the bottom inner groove frame 9 away from the center mounting disk 5, and the other end of the double-rod slide 101 is slidably connected to the adjacent bottom inner groove frame 9, and the double-rod slide 101 limits the moving trajectory of the lens clamp rod 10 relative to the bottom inner groove frame 9.

[0033] A movable wear rod 11 is coaxially slidably inserted inside the vertical sleeve rod 8, and the movable wear rod 11 is elastically connected to the vertical sleeve rod 8. An end opening frame 12 is arranged above each fixed-distance slide groove 7, and the end opening frame 12 is fixed to the circumferential side of the vertical coaxial rod 6. An end opening block 13 is slidably inserted inside the end opening frame 12, and the side of the end opening block 13 away from the axis of the central mounting plate 5 is a right-angle U-shaped depression. The upper end of the movable wear rod 11 is located inside the U-shaped depression structure of the adjacent end opening block 13, and the lower end of the movable wear rod 11 is located at the bottom Inside the inner groove frame 9, the movable penetration rod 11 is located on the side of the lens clamp rod 10 away from the axis of the central mounting plate 5. The lower end of the movable penetration rod 11 close to the lens clamp rod 10 is a right triangle. The inclined surface of the movable penetration rod 11 is close to the lens clamp rod 10. The movable penetration rod 11 is elastically connected to the vertical sleeve rod 8, and the inclined surface of the movable penetration rod 11 is controlled to be located inside the bottom inner groove frame 9. When the lens clamp rod 10 moves close to the side of the movable penetration rod 11, the lens clamp rod 10 gradually pushes the movable penetration rod 11 upward by contacting the inclined surface of the movable penetration rod 11.

[0034] The upper end of the movable penetrating rod 11 is elastically slidably plugged with two retracted card blocks 14, and the retracted card blocks 14 are located inside the concave structure of the adjacent end opening block 13. The U-shaped concave structure of the end opening block 13 is away from the end of the central mounting plate 5 and has an inclined expansion structure. The inner walls on both sides of the U-shaped concave structure of the end opening frame 12 are provided with groove structures adapted to the retracted card blocks 14. When the end opening frame 12 moves, the movable penetrating rod 11 is driven to move by the retracted card blocks 14. When the movable penetrating rod 11 moves upward, the retracted card blocks 14 can be driven to move upward and disengage from the end opening frame 12. The end opening frame 12 is horizontally arranged, and the end opening frame 12 is perpendicular to the axis of the central mounting plate 5. The plurality of end opening frames 12 are evenly distributed in a circular array along the axis of the center mounting disk 5, and the number of the fixed-distance slide grooves 7 is set to an even number greater than 3, so that the lens clamping rods 10 on both sides are symmetrically clamped with the lenses. After the vertical sleeve rod 8 drives the movable penetration rod 11 to reset away from the axis of the center mounting disk 5, when the end opening block 13 moves away from the axis of the center mounting disk 5, the U-shaped flared inclined surface of the end opening block 13 applies a thrust to the contacting retracted card block 14, pushing the retracted card block 14 into the movable penetration rod 11, so that the retracted card block 14 can re-enter the U-shaped recessed structure of the end opening block 13 for cooperation, so that the movable penetration rod 11 can be driven to move when the end opening block 13 moves again.

[0035] The upper end of the end opening block 13 is equipped with an articulated claw arm structure 15, the upper end of the articulated claw arm structure 15 is connected to the vertical coaxial rod 6, the outer surface of the vertical coaxial rod 6 is equipped with a power sliding frame A16, the articulated claw arm structure 15 is connected to the power sliding frame A16, the articulated claw arm structure 15 includes a telescopic articulated frame 151 and a side claw arm frame 152, the two ends of the telescopic articulated frame 151 are respectively rotatably connected to the end opening block 13 and the vertical coaxial rod 6, and the side claw arm frame 152 is located at the telescopic articulated frame 15 1, one end of the side claw arm 152 is rotatably connected to the upper telescopic end of the telescopic articulated frame 151, and the other end of the side claw arm 152 is rotatably connected to the power sliding frame A16. The power sliding frame A16 is located below the upper end of the telescopic articulated frame 151. When the power sliding frame A16 moves downward, the telescopic articulated frame 151 is pulled downward by the side claw arm 152 to rotate, and the end opening block 13 is pulled to move close to the axis of the central mounting plate 5, and the telescopic articulated frame 151 is correspondingly extended and retracted.

[0036] A power slide frame B17 is installed on the outer surface of the vertical coaxial rod 6. The power slide frame A16 and the power slide frame B17 can be installed with hydraulic cylinders and power telescopic rods to slide on the surface of the vertical coaxial rod 6. A one-way damping structure 18 is installed at one end of the vertical sleeve rod 8 located above the central mounting plate 5. The one-way damping structure 18 is connected to the power slide frame B17. The power slide frame B17 is located below the power slide frame A16. The one-way damping structure 18 includes a one-way gear block 181 and a one-way tooth plate 182. One end of the one-way tooth plate 182 is fixed to the power slide frame B17, and the other end of the one-way tooth plate 182 is meshed with the one-way gear block 181 near one end of the vertical sleeve rod 8. The other end of the one-way tooth plate 182 is elastically connected to the adjacent vertical sleeve rod 8. The axis of the one-way tooth plate 182 is perpendicular to the vertical sleeve rod 8, and the one-way gear block 181 is close to one side of the one-way tooth plate 182. It is a right-angled tooth-like structure. The right-angled teeth of the one-way tooth block 181 are close to the axis of the center mounting disk 5 on one side, and the tooth shape of the one-way tooth plate 182 is adapted to the tooth shape of the one-way tooth block 181. When the vertical sleeve rod 8 moves toward one side of the axis of the center mounting disk 5, the tooth inclined surface of the one-way tooth block 181 applies a thrust to the teeth of the one-way tooth plate 182 and continuously moves close to the vertical sleeve rod 8 elastically. After the retracted card block 14 is disengaged from the end opening block 13, the one-way tooth block 181 engages with the one-way tooth plate 182 to prevent the vertical sleeve rod 8 from being reset away from the center mounting disk 5. The lens clamping rod 10 can clamp the lens without loosening. When the lens needs to be removed, the power sliding frame B17 drives all the one-way tooth plates 182 to move upward and disengage from the one-way tooth block 181, so that the vertical sleeve rod 8 is reset under the pull of the corresponding horizontal tension telescopic rod 81.

[0037] A coating spray structure 19 is arranged below the central mounting plate 5. The coating spray structure 19 is installed through the upper surface of the supporting main platform 1. A discharge platform 20 is installed on the upper surface of the supporting main platform 1. The lens to be sprayed is placed above the discharge platform 20. The coating spray structure 19 includes a material spray head 191 and a flow control valve 192. The material spray head 191 is installed through the upper surface of the supporting main platform 1. The flow control valve 192 is installed at one end of the material spray head 191 above the supporting main platform 1. The horizontal and vertical power control frame 2 changes the horizontal and vertical positions of the power telescopic frame 4, controls the movement of the lens relative to the material spray head 191, and can fully spray the lens. At the same time, the flow control valve 192 controls the flow rate of the material sprayed from the material spray head 191 to control the thickness of the spraying.

[0038] The working principle is as follows: the horizontal and vertical power control frame 2 can change the horizontal and vertical positions of the power telescopic frame 4, and the power telescopic frame 4 can change the height of the central mounting plate 5, so that the lens to be processed is located between multiple lens clamping rods 10, and then the power sliding frame A16 moves downward, and pulls the telescopic hinge frame 151 downward through the side claw arm frame 152, and the telescopic hinge frame 151 rotates downward, and pulls the end opening block 13 close to the axis of the central mounting plate 5, driving multiple lens clamping rods 10 to approach the lens synchronously, and the vertical sleeve rod 8 drives the one-way tooth block 181 to continuously elastically expand and contract relative to the vertical sleeve rod 8 and engage with the one-way tooth plate 182 when moving. After a lens clamping rod 10 contacts the lens, when the vertical sleeve rod 8 continues to move, the lens clamping rod 10 slides in the bottom inner groove frame 9 under the obstruction of the lens. When moving, the lens clamp rod 10 gradually pushes the movable penetration rod 11 upward by contacting the inclined surface of the movable penetration rod 11, driving the retracted card block 14 to gradually disengage from the corresponding end opening block 13, and the corresponding vertical sleeve rod 8 will not move away from the center mounting plate 5 when the one-way tooth block 181 is engaged with the one-way tooth plate 182, so that the corresponding end opening block 13 will not continue to drive the movable penetration rod 11 below to move when moving, and then when the telescopic articulated frame 151 continues to rotate, the lens clamp rods 10 in other directions of the lens continue to move under the pull of the corresponding telescopic articulated frame 151, and after all the lens clamp rods 10 clamp the lenses, all the end opening blocks 13 are disengaged from the corresponding retracted card blocks 14, preventing the lens clamp rods 10 from applying excessive pressure on the lenses and causing damage.

[0039] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
