[0002] With the advancement of modern society, eyeglasses have become an essential item for many people. Sunglasses and prescription glasses are widely used in daily life, effectively protecting the eyes. When getting eyeglasses, the lenses need to be polished. However, existing lens polishing equipment has certain shortcomings, such as: 1.

Furthermore, it cannot perform multi-angle polishing on the lenses being processed, resulting in processing efficiency deficiencies. 2. When processing lenses of different materials, existing optical lens polishing equipment can overheat during polishing, easily damaging the lenses and affecting the processing results.

[0004] According to the aforementioned patent, when performing edge grinding on optical lenses, the squeezing and grinding of the optical lenses can easily damage them. Since optical lenses are relatively fragile, they need to be positioned during the grinding process. Therefore, there is a need for an automatic edge grinding machine that can position optical lenses and ensure their stability. Summary of the Invention

[0005] To address the problems existing in the current technology, this invention provides an automatic optical lens edging machine. The invention uses the cooperation between the top pressing component and the bottom support component to fix the optical lens in place. During the positioning of the optical lens, the limiting posts around the base limit the placement of the optical lens, keeping the optical lens in the middle position of the bottom support component. This ensures that the surface of the optical lens is evenly stressed when it is fixed, and also ensures that the optical lens can enter the rotating grinding mold, thereby improving the stability of optical lens processing.

[0010] Preferably, the upper support ring and the lower support ring have the same structure, both of which are in the shape of an inner cone, and both of the upper support ring and the lower support ring are fixedly fitted with rubber rings.

[0011] Preferably, the bottom midpoint pressing member and the top midpoint pressing member have the same structure. The bottom midpoint pressing member is provided with a push rod. The push rod is coaxially and movably set in the center of the fixed base. The fixed base is provided with a rod sleeve for the push rod to move. The end of the push rod facing the optical lens is provided with a rubber sleeve. The other end of the push rod is provided with a first anti-detachment ring. A first compression spring sleeved on the push rod is connected between the first anti-detachment ring and the rod sleeve.

[0012] Preferably, the lower support ring and the upper support ring are respectively provided with a lower water bladder and an upper water bladder. The edge of the lower water bladder is connected to the corresponding top rod and the lower support ring, and the edge of the upper water bladder is connected to the corresponding top rod and the upper support ring. A water channel is opened in the top rod along its axial direction. The end of the top rod facing outward is open, and the end of the top rod with a rubber sleeve is provided with a water inlet that communicates with the water channel. A water filling space is formed between the lower water bladder and the upper water bladder and the water inlet of the corresponding top rod. Each open end of the top rod is provided with a connecting pipe that communicates with the water channel.

[0013] Preferably, the limiting post can move along the axis of the top rod. A post sleeve for guiding the limiting post is fixed on the base. A sleeve sleeve is provided on the bottom of the fixed base and coaxially with it. A sleeve plate is movably sleeved on the sleeve. The lower end of each limiting post is fixedly connected to the sleeve plate. A second anti-detachment ring is provided at the lower end of the sleeve. A second compression spring sleeved on the sleeve is connected between the second anti-detachment ring and the sleeve plate. A first through hole is opened on the fixed base. An outer ring sealing curtain and an inner ring sealing curtain are respectively connected between the sleeve plate and the fixed base and around the first through hole. A water-filled space is formed between the outer ring sealing curtain and the inner ring sealing curtain to allow water to flow out of the first through hole to move the sleeve plate.

[0014] Preferably, a housing is coaxially fitted onto the top of the movable top plate, the housing having a cavity, a second through hole communicating with the cavity being provided on the movable top plate, and a spray hole being provided on the outer ring of the housing, which is directly opposite the edge of the optical lens and communicates with the cavity.

[0015] Preferably, the rotating grinding tool has a ring-shaped structure, and the edge of the rotating grinding tool and the position corresponding to each limiting post are provided with a notch for its movement.

[0016] The present invention also provides an automatic edge grinding method for optical lenses, comprising the following steps:

[0017] S1, Place the optical lens on the bottom support assembly and between the four limiting posts;

[0018] S2, activate the top pressing component to press the optical lens onto the bottom support component;

[0022] The advantages of this application compared to the prior art are:

[0023] 1. This invention, through the cooperation between the top pressing component and the bottom supporting component, enables the optical lens to be fixed within it. During the positioning of the optical lens, the limiting posts around the base limit the placement of the optical lens, keeping the optical lens in the middle position of the bottom supporting component. This ensures that the surface of the optical lens is evenly stressed when it is fixed, and also ensures that the optical lens can enter the rotating mold, thereby achieving effective edge grinding of the optical lens and improving the stability of optical lens processing.

[0024] 2. The present invention provides fixed-point support for the optical lens by using bottom midpoint pressing members and top midpoint pressing members, keeping the optical lens in the middle position and preventing the optical lens from tilting. This achieves the fixation of the optical lens in a stable state, improves the effect of grinding the edge of the optical lens, and avoids damage to the optical lens when subjected to grinding force in a tilted state.

[0025] 3. The present invention uses the upper and lower support rings to press against the optical lens, thus fixing the optical lens and preventing it from shaking or rotating with the rotating mold. Since the upper and lower support rings are respectively located on the outer ring of the corresponding movable top plate and fixed base plate, only the edge of the optical lens is exposed, preventing the waste generated during grinding from falling into the un-grinded area and causing scratches on its surface. This achieves stable processing of the optical lens and improves the processing effect. Attached Figure Description

[0051] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0052] See Figures 1-4 As shown, an automatic optical lens edging machine includes a base 1, a fixing mechanism 2 for positioning an optical lens 6 on the base 1, a rotating abrasive 3 for grinding the edge of the optical lens 6 on the fixing mechanism 2, the rotating abrasive 3 being able to rotate around the center of the base 1, a rotating driver 4 for driving the rotating abrasive 3 to rotate on the fixing mechanism 2, and a limiting post 5 for holding the optical lens 6 at the midpoint position on all four sides of the base 1 around the fixing mechanism 2, the fixing mechanism 2 having a bottom support component 21 and a top pressing component 22, the bottom support component 21 being disposed on the base 1, the top pressing component 22 being disposed directly above the bottom support component 21, the top pressing component 22 being able to move toward the bottom support component 21, and when the top pressing component 22 moves toward the bottom support component 21, the optical lens 6 is in a state of being squeezed between the two.

[0053] When the optical lens 6 is edge-grinding, firstly, the optical lens 6 is placed on the bottom support assembly 21 and confined between the limiting posts 5 around the base 1. The optical lens 6 is held in the center of the base 1. Then, the top pressing assembly 22 presses the optical lens 6, causing it to be pressed tightly between the bottom support assembly 21 and the top pressing assembly 22, thus stabilizing it. After the optical lens 6 is fixed, the limiting posts 5 move away from the edge of the optical lens 6. Since the optical lens 6 is supported on the bottom support assembly 21, as the optical lens 6 is pressed down, guided by the limiting posts 5, the optical lens 6 is pressed into the rotating grinding mold 3. The edge of the optical lens 6 contacts the rotating grinding mold 3. At this time, the rotary driver 4 drives the rotating grinding mold 3 to rotate around the center of the optical lens 6, completing the grinding of the edge of the optical lens 6. After the burrs on the edge of the optical lens 6 are ground off, the top pressing assembly 22 moves away from the bottom support assembly 21, and finally the optical lens 6 is removed.

[0054] See Figures 5-7 As shown, the bottom support assembly 21 is provided with a bottom midpoint pressing member 23 for supporting the midpoint of the concave surface of the optical lens 6, and the top pressing assembly 22 is provided with a top midpoint pressing member 24 for pressing down the midpoint of the convex surface of the optical lens 6.

[0055] When the top pressing component 22 presses the optical lens 6 down onto the bottom support component 21, the bottom midpoint pressing component 23 supports the bottom midpoint of the optical lens 6, and the limiting posts 5 around the base 1 keep the optical lens 6 stable. As the top pressing component 22 is driven, the top midpoint pressing component 24 presses against the top midpoint of the optical lens 6 and presses it down until the optical lens 6 is stabilized, and then the edge is polished.

[0056] See Figure 6 and Figure 7 As shown, the bottom support assembly 21 is provided with a fixed chassis 211, the top pressing assembly 22 is provided with a movable top plate 221, the bottom midpoint pressing member 23 and the top midpoint pressing member 24 are respectively installed on the fixed chassis 211 and the movable top plate 221, the top outer ring of the fixed chassis 211 is coaxially provided with a lower support ring 212, the bottom outer ring of the movable top plate 221 is coaxially provided with an upper support ring 222, and the movable top plate 221 is also connected to a lifting member 223 for moving it.

[0057] When the optical lens 6 is pressed downward by the top midpoint pressing member 24, the lifting member 223 drives the movable top plate 221 to move up and down. After the optical lens 6 contacts the top midpoint pressing member 24, the optical lens 6 is pressed downward. The bottom midpoint pressing member 23 gradually moves down until the lower surface of the optical lens 6 contacts the lower support ring 212 of the fixed base plate 211. The optical lens 6 can no longer move, while the movable top plate 221 continues to press down. The movable top plate 221 continues to move down relative to the top midpoint pressing member 24 until the upper support ring 222 contacts the upper surface of the optical lens 6, so that the optical lens 6 is firmly pressed in it, ensuring the stability of the optical lens 6.

[0058] See Figure 6 and Figure 7 As shown, the upper support ring 222 and the lower support ring 212 have the same structure. Both the upper support ring 222 and the lower support ring 212 are in the shape of an inner cone. The inner rings of the upper support ring 222 and the lower support ring 212 are fixedly fitted with rubber rings 2121.

[0059] When the upper support ring 222 and the lower support ring 212 come into contact with the optical lens 6, the inner rings of both are fitted with rubber rings 2121. Therefore, the contact between the rubber rings 2121 and the surface of the optical lens 6 prevents the surface of the optical lens 6 from being dented or scratched.

[0060] See Figures 6-9As shown, the bottom midpoint pressing member 23 and the top midpoint pressing member 24 have the same structure. The bottom midpoint pressing member 23 is provided with a push rod 231. The push rod 231 is coaxially and movably set at the center of the fixed base 211. The fixed base 211 is provided with a rod sleeve 232 for the push rod 231 to move. The end of the push rod 231 facing the optical lens 6 is provided with a rubber sleeve 2311. The other end of the push rod 231 is provided with a first anti-detachment ring 233. A first compression spring 234 sleeved on the push rod 231 is connected between the first anti-detachment ring 233 and the rod sleeve 232.

[0061] When the movable top plate 221 moves downward relative to the fixed base plate 211, the end sleeve 2311 of the push rod 231 presses against the surface of the optical lens 6, causing the optical lens 6 to be squeezed downward. At this time, the push rod 231 of the bottom midpoint pressing member 23 moves downward along the corresponding sleeve 232 under pressure. The first compression spring 234 connected to it is in a stretched state until the optical lens 6 contacts the lower support ring 212 and stops. The movable top plate 221 continues to move downward. At this time, the push rod 231 of the top midpoint pressing member 24 is also in a pressing state against the optical lens 6. The movable top plate 221 moves relative to the push rod 231. At this time, the first compression spring 234 connected to it is in a stretched state until the upper support ring 222 contacts the optical lens 6 and stops, thus completing the fixation of the optical lens 6.

[0062] See Figure 6 and Figure 7 As shown, a lower water bladder 235 and an upper water bladder 241 are respectively provided in the lower support ring 212 and the upper support ring 222. The edge of the lower water bladder 235 is connected to the corresponding top rod 231 and the lower support ring 212, and the edge of the upper water bladder 241 is connected to the corresponding top rod 231 and the upper support ring 222. A water channel 2312 is opened in the top rod 231 along its axial direction. The end of the top rod 231 facing outward is open. The end of the top rod 231 with a rubber sleeve 2311 has a water outlet 2313 that communicates with the water channel 2312. A water-filling space is formed between the lower water bladder 235 and the upper water bladder 241 and the water outlet 2313 of the corresponding top rod 231. Each top rod 231 has a connecting pipe 2314 that communicates with the water channel 2312 at its open end.

[0063] After the optical lens 6 is fixed between the upper support ring 222 and the lower support ring 212, the top rod 231 is connected to the existing water pump through the connecting pipe 2314, and water is supplied to the water channel 2312. Subsequently, water is supplied through the water outlet 2313 into the water-filling space of the corresponding lower water bladder 235 and upper water bladder 241, causing the upper water bladder 241 and lower water bladder 235 to expand. The water supply is stopped when the upper water bladder 241 and lower water bladder 235 expand to the point of pressing against the surface of the optical lens 6. This further presses the optical lens 6 between the expanded upper water bladder 241 and lower water bladder 235. Due to the water-filling method, the compression is kept in a flexible state, preventing the optical lens 6 from being crushed and further stabilizing the optical lens 6. In addition, the contact between the upper water bladder 241 and lower water bladder 235 and the surface of the optical lens 6 also has a cooling effect on the optical lens 6, which cools down the polished edge of the optical lens 6 and improves the polishing effect.

[0064] See Figure 6 and Figure 7 As shown, the limiting post 5 can move along the axis of the top rod 231. The base 1 is fixedly provided with a post sleeve 51 for guiding the limiting post 5. The bottom of the fixed base 211 is coaxially provided with a sleeve 52 sleeved on the rod sleeve 232. A sleeve plate 53 is movably sleeved on the sleeve 52. The lower end of each limiting post 5 is fixedly connected to the sleeve plate 53. The lower end of the sleeve 52 is provided with a second anti-detachment ring 521. A second compression spring 54 sleeved on the sleeve 52 is connected between the second anti-detachment ring 521 and the sleeve plate 53. The fixed base 211 is provided with a first through hole 2111. The sleeve plate 53 and the fixed base 211 are respectively connected with an outer ring sealing curtain 531 and an inner ring sealing curtain 532 around the first through hole 2111. A water-filled space is formed between the outer ring sealing curtain 531 and the inner ring sealing curtain 532, which allows water to flow out of the first through hole 2111 to move the sleeve plate 53.

[0065] When the optical lens 6 is fixed, the limiting post 5 is in the state between the fixed base 211 and the movable base. After the optical lens 6 is fixed, as the lower water bladder 235 is filled with water, some water will enter the water-filled space formed between the outer ring sealing curtain 531 and the inner ring sealing curtain 532 through the first through hole 2111. Under water pressure, the sleeve 53 is squeezed, causing the sleeve 53 to move up and down in the sleeve 52. The second compression spring 54 is in a compressed state. Since the limiting post 5 is fixedly connected to the sleeve 53, the limiting post 5 is driven down along the post sleeve 51, thereby moving away from the movable top plate 221, so that the edge of the optical lens 6 is exposed, which is convenient for the rotating grinding tool 3 to rotate and grind the edge of the optical lens 6.

[0066] See Figure 6 , Figure 7 and Figure 10As shown, a housing 224 is coaxially fitted on the top of the movable top plate 221. The housing 224 has a cavity. A second through hole 2211 communicating with the cavity is opened on the movable top plate 221. A spray hole 2241 is opened on the outer ring of the housing 224, which is directly opposite the edge of the optical lens 6 and communicates with the cavity.

[0067] When the upper water bladder 241 is filled with water, some of the water enters the housing 224 through the second through hole 2211. Under the action of water pressure, the water will be sprayed out from the spray hole 2241. The spray direction is directly facing the edge of the optical lens 6, which causes the edge of the optical lens 6 to be polished and cleaned at the same time, thus improving the processing effect of the optical lens 6.

[0068] See Figure 4 As shown, the rotating grinding tool 3 has a ring-shaped structure, and the edge of the rotating grinding tool 3 and the position corresponding to each limiting post 5 are provided with notches for its movement.

[0069] When the rotary abrasive 3 is not activated, the limiting post 5 is in the notch of the rotary abrasive 3. When the limiting post 5 leaves, the rotary abrasive 3 is not obstructed. At this time, the rotary driver 4 drives the rotary abrasive 3 to rotate around the center of the optical lens 6 to achieve the grinding of its edge.

[0070] An automated edge grinding method for optical lenses includes the following steps:

[0071] S1, place the optical lens 6 on the bottom support assembly 21 and between the four limiting posts 5;

[0072] S2, activate the top pressing component 22 to press the optical lens 6 onto the bottom support component 21;

[0073] S3, fill the lower water bladder 235 and the upper water bladder 241 with water, so that the optical lens 6 is further secured therein, and at this time the limiting post 5 is away from the edge of the optical lens 6.

[0074] S4, the rotary driver 4 is activated, driving the rotary abrasive 3 to rotate and polish the edge of the optical lens 6;

[0075] S5, water is sprayed through the nozzle 2241 on the housing 224 facing the edge of the optical lens 6 to clean the polished edge.

[0076] The present invention uses the cooperation between the top pressing component 22 and the bottom support component 21 to fix the optical lens 6 therein. During the positioning of the optical lens 6, the limiting posts 5 around the base 1 limit the placement of the optical lens 6, keeping the position of the optical lens 6 in the middle of the bottom support component 21. This ensures that the surface of the optical lens 6 is evenly stressed when it is fixed, and also ensures that the optical lens 6 can enter the rotating mold 3, thereby improving the stability of the optical lens 6 processing.

[0077] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
