[0002] Lenses are transparent materials with one or more curved surfaces. They adjust the light entering the eyes to correct vision, protect eye safety, or clinically treat eye diseases. Lenses can be divided into the following three types: glass lenses, resin lenses, and space lenses (PC lenses). The optical design of the lens determines the visual effect. Common surface designs on the market include spherical lenses, aspherical lenses, double aspherical lenses, and multifocal progressive lenses. Stress-free lenses are lenses that have eliminated internal stress.

[0003] A rubber ring is a ring-shaped object made of rubber, which is often used to wrap around the outside of a component to protect the object or seal the installation location.

[0021] 1. The present invention sets up a clamping and moving integrated component. First, the rubber ring to be assembled is installed in this device. Specifically, the first cylinder and the second cylinder are used to drive the pressure plates of the fixing part and the driving part to open, and then the two ends of the rubber ring are placed between the clamping plate and the bottom plate. The clamping plate is further closed by the cylinder to limit the end of the rubber ring. At the same time, the two sides of the rubber ring are pulled, and the elasticity of the rubber ring is used to sleeve the rubber ring into the second card slot on the outside of the driven part. At this time, the electric guide rail and the dust collection component are started. After the electric guide rail is running, it will drive the magnetic block to slide in its inner wall (the driving force of the electric guide rail on the magnetic block is greater than the magnetic attraction force exerted on the magnetic block), and the movement of the magnetic block will drive the driven part to move synchronously, so that the driven part will The follower moves along the inner wall of the rubber ring. During the movement, the dust suction component in the second card slot of the driven part will remove dust and impurities on the inner wall of the rubber ring, thereby ensuring the quality of subsequent assembly of the rubber ring and the lens. After the dust removal process of the rubber ring is completed, the rubber ring is placed in the first card slot for clamping and limiting. After the assembly of the lens and the rubber ring is completed, the electric guide rail is started again to drive the driven part to move. At this time, the movement of the driven part will be assisted by the roller to perform an extrusion movement along the engaging position of the rubber ring and the lens, thereby making the engagement of the rubber ring and the lens tighter. At the same time, the protrusion located on the side of the first card slot will also squeeze the rubber ring from the outside, further improving the assembly tightness of the rubber ring and the lens, that is, the assembly quality.

[0022] 2. The present invention provides an integrated clamping and moving component. When assembling the lens and the rubber ring, the driving rod is first pushed inward. The movement of the driving rod will push the driving part to move outward. At the same time, the extrusion block located on the outer wall of the driving rod will squeeze the driven rod to move to both sides, that is, drive the driven part to move outward, thereby achieving the purpose of expanding the inner diameter of the rubber ring. Then, the lens to be assembled can be placed inside the rubber ring, and the limiting force on the driving rod is released. At this time, the driving part and the driven part will be quickly reset under the action of the reset spring. Therefore, the stretched rubber ring will also be quickly reset and the engagement assembly with the lens is completed in an instant, which is convenient and quick, and greatly improves the assembly efficiency of the lens and the rubber ring.

[0046] See also Figure 3 , the driving part 302 and the driven part 303 are driven by the movement of the driving rod 501;

[0047] Specifically, the driving assembly 5 includes a driving rod 501 that is slidably connected to the inner wall of the chassis 1, and one end of the driving rod 501 extends to the outside of the chassis 1, and the other end of the driving rod 501 extends to the outer wall of the first magnetic block 4012 at the bottom of the driving part 302 and is fixedly connected.

An extrusion block 503 is fixedly sleeved on the outer wall of the driving rod 501 to realize extrusion driving of the driven rod 502;

[0048] The working principle of the present invention is as follows: first, the rubber ring 2 to be assembled is installed in the device. Specifically, the first cylinder 306 and the second cylinder 309 are used to drive the pressure plates of the fixing part 301 and the driving part 302 to open. Then, the two ends of the rubber ring 2 are placed between the clamping plate and the bottom plate. The clamping plate is further closed by the cylinder, thereby achieving the end position limit of the rubber ring 2.

[0049] At the same time, the two sides of the rubber ring 2 are pulled, and the elasticity of the rubber ring 2 is used to fit the rubber ring 2 into the second slot 316 on the outer side of the driven part 303. At this time, the electric guide rail 6 and the dust suction component 317 are started. After the electric guide rail 6 is running, it will drive the magnetic block 4011 to slide on its inner wall (the driving force of the electric guide rail 6 on the magnetic block 4011 is greater than the magnetic attraction force on the magnetic block 4011). The movement of the magnetic block 4011 will drive the driven part 303 to move synchronously, so that the driven part 303 will move along the inner wall of the rubber ring 2 on the inner side of the rubber ring 2. During the movement, the dust suction component 317 in the second slot 316 of the driven part 303 will remove dust and impurities on the inner wall of the rubber ring 2, thereby ensuring the subsequent assembly quality of the rubber ring 2 and the lens.

[0050] Furthermore, when assembling the lens and the rubber ring 2, the rubber ring 2 is placed in the first clamping groove 312 for clamping and limiting, and then the driving rod 501 is pushed to move inward. The movement of the driving rod 501 will push the driving part 302 to move outward. At the same time, the squeezing block 503 located on the outer wall of the driving rod 501 will squeeze the driven rod 502 to move to both sides, that is, drive the driven part 303 to move outward, thereby achieving the purpose of expanding the inner diameter of the rubber ring 2. Then, the lens to be assembled can be placed inside the rubber ring 2, and the limiting force on the driving rod 501 is released. At this time, the driving part 302 and the driven part 303 will be quickly reset under the action of the reset spring 404. Therefore, the stretched rubber ring 2 will also be quickly reset and the lens will be engaged and assembled in an instant, which is convenient and quick, greatly improving the assembly efficiency of the lens and the rubber ring 2.

[0051] It is worth noting that after the dust removal process on the rubber ring 2 is completed, the electric guide rail 6 is started again to drive the driven part 303 to move. At this time, the movement of the driven part 303 will be assisted by the roller 314 to squeeze along the engagement position of the rubber ring 2 and the lens, thereby making the rubber ring 2 and the lens engage more tightly.

[0052] In addition, the protrusion 315 located on the side of the first slot 312 can also squeeze the rubber ring from the outside, further improving the assembly tightness of the rubber ring 2 and the lens, that is, further improving the assembly quality of the rubber ring 2 and the lens.

[0053] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
