Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical lens processing, and in particular to an anti-breakage clamping mechanism for the edge of an optical lens. Background Technology
[0002] Optical lenses are transparent materials that control light through refraction or reflection. They are widely used in eyeglasses, cameras, microscopes, and other equipment. Depending on the application, lenses can be made of different materials and come in single-layer, composite, and multi-layer coated types. The design of lenses adjusts their optical properties based on curvature and thickness to achieve visual correction or improve image quality. Modern optical lenses are not only used in everyday eyeglasses but are also widely used in professional fields such as fiber optics and laser technology. With technological advancements, their performance continues to improve.
[0003] Optical lens processing involves precision processes such as cutting, grinding, polishing, and coating optical materials to obtain the desired optical properties. A rough blank is cut according to design requirements, and then grinding and polishing are used to improve surface quality and optical precision, ensuring the clarity and accuracy of light transmission. Finally, coating processes are used to improve light transmittance, reduce reflection, or enhance special functions such as UV resistance and scratch resistance. The entire processing requires high-precision equipment and technology to ensure the optical performance and stability of the lens.
[0004] During the lens edging process, the lens needs to be clamped on both sides by a clamping mechanism and fixed on the edging machine. The edging effect is achieved by the rotation of the grinding disc and the lens itself. However, the contact surface between the clamping mechanism and the lens on the traditional edging machine is relatively hard, which can easily cause chipping or pitting during the edging process, resulting in the scrapping of the lens and increasing production costs. To address this issue, an anti-chipping clamping mechanism for the edge of an optical lens is proposed. Utility Model Content

[0034] The clamping assembly includes a housing 6, a servo motor 7 fixedly connected to the rear of the housing 6, a turntable 8 fixedly connected to the output end of the servo motor 7, a sliding frame 9 slidably connected to the front of the turntable 8, sliding rods 10 slidably connected to the upper and lower sides of the sliding frame 9, a push rod 11 rotatably connected to the left side of the sliding frame 9, a suction head 13 slidably connected to the middle of the housing 6, rubber rings 12 fixedly connected to the right end of the suction head 13 and the left end of the push rod 11, and a formwork 14 fixedly connected to the outside of the suction head 13. The housing 6 is used to connect and protect the internal parts. An air pump and a motor are installed on the left side of the housing 6 to drive the suction head 13 to rotate and simultaneously allow the suction head 13 to grip the lens. The servo motor 7 drives the turntable 8 to rotate, and the turntable 8 drives the sliding frame 9 to move left and right. The sliding rods 10 limit the movement of the sliding frame 9. The sliding frame 9 can only move left and right without wobbling. The push rod 11 is used to fix the lens and keep it stable. The rubber ring 12 is for direct contact with the lens to protect it from damage. The suction head 13 is used to suck up the lens for easy fixation. The shaper 14 is for cooperating with the contouring plate 5 to process the lens into the same shape as the shaper 14. The left and right ends of the sliding rod 10 are fixedly connected to the inside of the housing 6 to keep the sliding rod 10 stable. The upper and lower ends of the sliding frame 9 are slidably connected to the inner wall of the housing 6 to keep the sliding frame 9 stable.

[0035] Reference Figure 2 , Figure 4 , Figure 5The replacement components include a retaining ring 15, which is fixedly connected to the middle of the outer casing 6. A rotating ring 16 is rotatably connected to the outside of the retaining ring 15. Four pull ropes 17 are fixedly connected to the inside of the rotating ring 16. Springs 18 are fixedly connected to the outside of the pull ropes 17. A baffle 19 is fixedly connected to the inside of the springs 18. A fixing rod 20 is fixedly connected to the inside of the baffle 19. The retaining ring 15 is used to connect and limit other parts. The rotating ring 16 encloses the retaining ring 15 and is connected to the pull ropes 17 for easy manual rotation. The pull ropes 17 are used to pull the baffle 19 to move. The springs 18 are used to allow the baffle 19 to automatically reset. The fixing rod 20 can only move in a specified direction under the limitation of the retaining ring 15 and will not move or wobble. The baffle 19 is fixed to its outside to prevent it from being fixed. The rod 20 falls off when it exceeds its range of motion. The fixing rod 20 is used to fix the suction head 13 and facilitate the replacement of the tool 14. The pull rope 17 is externally slidably connected to the inside of the fixing ring 15. The inside of the pull rope 17 is fixedly connected to the outside of the baffle 19, so that the pull rope 17 can pull the baffle 19 to move. The outside of the spring 18 is fixedly connected to the inside of the fixing ring 15 to keep the spring 18 stable. The outside of the baffle 19 is externally slidably connected to the inner wall of the fixing ring 15. The fixing rod 20 is externally slidably connected to the inside of the fixing ring 15. The fixing ring 15 simultaneously restricts the movement direction of the baffle 19 and the fixing rod 20.

The fixing rod 20 passes through the outer shell 6 and is inserted into the inside of the suction head 13 to achieve fixation.
[0036] Working principle: When using this device to process lenses, first change the mold 14 according to the desired lens shape. By rotating the fixing ring 15, the pull rope 17 pulls the baffle 19 to compress the spring 18, causing the fixing rod 20 to retract into the fixing ring 15. Then, pull the suction head 13 out of the outer shell 6 and insert it into the corresponding suction head 13 of the mold 14. At this time, release the rotating ring 16. Under the limit of the fixing ring 15, the spring 18 pushes the baffle 19, pushing out the fixing rod 20, so that the fixing rod 20 is inserted into the suction head 13, fixing the suction head 13 in place, thus realizing the change of mold 14. Then, control the air inside the outer shell 6. The pump operates and places the lens onto the suction head 13. The lens is directly adsorbed onto the suction head 13 by suction. Then, the servo motor 7 is controlled to operate, driving the turntable 8 to rotate. Under the limit of the slide rod 10, the slide frame 9 is pushed to slide to the left, and the push rod 11 moves synchronously, clamping the lens between the push rod 11 and the suction head 13. The rubber ring 12 prevents damage to the lens. Finally, the suction head 13 is controlled to rotate and the drive system 2 is operated. The drive system 2 drives the rotating rod 3 to rotate, causing the grinding disc 4 to rotate synchronously. With the cooperation of the contouring disc 5 and the shaping tool 14, the edge grinding begins. The overall operation is time-saving and convenient.
