Description

Technical Field

[0001] The present invention relates to the technical field of glasses production, and specifically to a lens positioning, clamping and grinding device for glasses production. Background Art

[0002] As common vision correction or decorative articles in people's lives, the quality of the lenses of glasses is crucial. During the production process of lenses, grinding is one of the key links. Traditional lens grinding methods have many drawbacks. For example, when workers hold the lenses by hand to grind, not only is the labor intensity high, which is prone to fatigue, thus leading to a reduction in work efficiency, but also it is difficult to ensure the accuracy and consistency of grinding with manual operation. There are also many problems with some existing lens positioning and clamping devices. On the one hand, since glasses lenses are usually two symmetrical pieces with a curvature, some single-group clamping heads cannot process two lenses simultaneously, and it is also difficult to stably position and clamp the lenses with a curvature. Over-clamping is likely to damage the lenses, while insufficient clamping force will cause the lenses to shift during grinding. On the other hand, these devices often cannot flexibly rotate the lenses for grinding according to the shape of the frame, and additional grinding devices need to be designed and installed, with poor practicability. If manual hand-held grinders are used for grinding, it will be even more time-consuming and laborious. Summary of the Invention

[0003] To achieve the above objectives, the present invention is realized through the following technical solutions: A lens positioning, clamping and grinding device for glasses production, comprising: a base, on both sides of the top of the base, there are fixedly installed support plates, inside both sides of the support plates, there are provided card slots, and inside the card slots, there are fixedly installed card racks; An adjustment component, the adjustment component is fixedly installed between adjacent surfaces of the card racks, the adjustment component is erected on the middle of the top of the base through the card racks, and on both sides of the top of the adjustment component, there are fixedly installed electric grinding wheels; A support component, the support component is fixedly installed in the middle of the outer surface of the adjustment component, and the support component is fixedly installed above the base through the adjustment component; A clamping component, there are two clamping components, and both clamping components are slidably installed inside the support component. During the production of glasses, first, the staff places two symmetrical glasses lenses inside the support component, and then adjusts the positions of the clamping components on both sides of the support component according to the size of the lenses, so that the clamping components clamp on both sides of the lenses to position the lenses before grinding. Then, the staff adjusts the positions of the electric grinding wheels on both sides of the adjustment component, so that the electric grinding wheels move to fit the lenses. Then, the staff starts the electric grinding wheels to make the electric grinding wheels rotate and grind the two lenses simultaneously, thereby improving the lens processing efficiency.

[0004] Preferably, the adjusting assembly includes an inner sliding frame, and sliding frames are slidably installed at both ends inside the inner sliding frame. There are two sliding frames, and the two sliding frames are symmetrically arranged with the inner sliding frame as the center. Circular blocks are fixedly installed at the bottoms of the sliding frames. A collar is fixedly installed at the middle of the bottom of the inner sliding frame. An adjusting rod is movably installed inside the collar. A card is rotatably installed on the outer surface of the adjusting rod. A first spring is sleeved on the surface of the adjusting rod close to the card, and the first spring is adapted to be pressed against the collar. A limiting folding plate is fixedly installed on the surface of the adjusting rod away from the card, and the limiting folding plate is adapted to the circular block. After the lens is clamped and positioned, the staff pulls the adjusting rod outwards. At this time, the adjusting rod slides inside the collar, and the first spring sleeved on the surface of the adjusting rod is deformed by the displacement of the adjusting rod and is pressed against the collar. The limiting folding plate installed outside the adjusting rod moves along with the adjusting rod to slide the circular blocks on both sides towards each other, so that the sliding frames connected to the circular blocks slide towards each other, thereby adjusting the position of the sliding frames inside the inner sliding frame, so that the electric grinding wheels installed above the sliding frames move towards each other to grind the lens.

[0005] Preferably, the sliding frame is fixedly installed at the bottom of the electric grinding wheel, and both sides of the outer surface of the sliding frame are fixedly connected to the clamping frame and the supporting assembly. The sliding frame is fixedly installed between the opposite surfaces of the supporting plate through the clamping frame. After the card installed on the surface of the adjusting rod is pulled to the outside of the inner sliding frame, the staff rotates the card so that the card is clamped on the outside of the inner sliding frame to limit the sliding frame, which can fix the position of the electric grinding wheel during grinding without the need for the staff to keep pushing hard.

[0006] Preferably, the inner sliding frame includes an inner support cavity, a second spring is installed inside the inner support cavity, and a housing is sleeved on the outer surface of the inner support cavity. Positioning grooves are opened on both sides of the outer surface of the housing.

[0007] Preferably, a sliding groove is provided between the inner support cavity and the housing. The second spring is fixedly installed between the opposite surfaces of the sliding frame, and the sliding frame is slidably installed inside the sliding groove. The circular block is adapted to the positioning groove. When the limiting folding plate drives the circular block and the sliding frame to slide towards the positioning groove, the sliding frame presses the second spring, causing the second spring to deform and contract. After the lens grinding is completed, the staff rotates the card to loosen the card stuck on the housing. At this time, the first spring and the second spring rebound and reset, and the electric grinding wheel installed on the sliding frame moves back to its original position, facilitating the staff to take out the ground lens.

[0008] Preferably, the support assembly includes support bent frames. There are two support bent frames. A round rod is fixedly installed between the opposite surfaces of the two support bent frames. A base frame is fixedly installed on the outer surface of the round rod. Connecting blocks are fixedly installed on both sides of the top of the base frame. A bent arc plate is fixedly installed on the top of the connecting block. An installation rod is threadedly installed in the middle of the bent arc plate. A cushion block is fixedly installed at the bottom of the installation rod. The support bent frames and the base frame support the clamping assembly above the base. After the staff clamps the lens between the two side push clamps, rotate the installation rod so that the installation rod moves within the bent arc plate, so that the cushion block installed at the bottom of the installation rod fits above the lens. The cushion block is made of rubber material. The cushion block and the push clamp cooperate to clamp the side of the lens from multiple positions, and reduce the vibration of the lens during grinding, playing a role in assisting the synchronous clamping of the push clamp for positioning and clamping, thereby improving the stability of the lens during grinding, and using flexible clamping material to avoid wear on the side of the lens during grinding.

[0009] Preferably, the support bent frame is fixedly installed at the middle of the outer surface of the sliding frame. There are two connecting blocks, and both of the two connecting blocks are slidably connected to the clamping assembly.

[0010] Preferably, the clamping assembly includes a limiting push frame. A connecting plate is fixedly installed at the middle of the outer surface of the limiting push frame. A push clamp is fixedly installed on the outer surface of the connecting plate. The push clamp penetrates through the connecting block and extends to the outside. The push clamp is slidably installed inside the connecting block. The staff pushes the limiting push frame from both sides, so that the limiting push frame drives the push clamp to slide inside the connecting block. At this time, the two side push clamps displace from both sides to the middle and symmetrically clamp the two lenses between the push clamps. The limiting push frame is stuck outside the connecting block, which can stably position and clamp the lens with a curvature on the premise of avoiding lens damage, and prevent the lens from shifting during grinding.

[0011] Preferably, the push clamp includes a sliding piece. A protective piece is fixedly installed on the outer surface of the sliding piece. A clamping pad is fixedly installed at the middle of the outer surface of the protective piece. A clamping groove is formed inside the clamping pad. The lens is clamped inside the clamping groove. The clamping pad outside the clamping groove is made of flexible material. Since the shapes of the spectacle frames are diverse and the lenses themselves have a curvature, when the two lenses are placed in the clamping groove, the flexible clamping pad is deformed by the curvature of the lens and fits on the side of the lens according to the curvature of the lens. Moreover, the flexible clamping pad enhances the friction force when clamping the lens, realizing the simultaneous positioning and clamping of the left and right lenses, avoiding lens damage, and effectively preventing the lens from running off during the grinding process.

[0012] Preferably, the sliding piece is fixedly installed on the outer surface of the connecting plate, the sliding piece is slidably installed inside the connecting block, and the clamping pad and the clamping groove are arranged in an arc shape to be adapted to the arc-shaped lens. When the electric grinding wheel grinds the lens, the protective piece arranged on the outer side of the clamping pad blocks the flying dust and chips, so as to limit the falling range of the dust and chips and reduce the scattering range of the dust and chips.

[0013] The present invention provides a lens positioning, clamping and grinding device for glasses production. It has the following beneficial effects: First, in this lens positioning, clamping and grinding device for glasses production, the lens is clamped inside the clamping groove, and the clamping pad outside the clamping groove is made of a flexible material. Since the frame shapes are diverse and the lens itself has a curvature, when two lenses are placed in the clamping groove, the flexible clamping pad is deformed by the influence of the lens curvature and fits against the side of the lens according to the lens curvature. Moreover, the flexible clamping pad enhances the friction when clamping the lens, realizing the simultaneous positioning and clamping of the left and right lenses, avoiding lens damage, and effectively preventing the lens from running off during the grinding process.

[0014] Second, in this lens positioning, clamping and grinding device for glasses production, after the lens is clamped and positioned, the staff pulls the adjusting rod outwards. At this time, the adjusting rod slides inside the collar, and the first spring sleeved on the surface of the adjusting rod is deformed by the displacement of the adjusting rod and is squeezed against the collar. The limiting folding plate installed outside the adjusting rod moves along with the adjusting rod to slide the two round blocks towards each other, so that the sliding frame connected to the round blocks slides towards each other, thereby adjusting the position of the sliding frame inside the inner sliding frame, and enabling the electric grinding wheels installed above the sliding frame to move towards each other to grind the lens.

[0015] Third, in this lens positioning, clamping and grinding device for glasses production, after the card installed on the surface of the adjusting rod is pulled to the outside of the inner sliding frame, the staff rotates the card so that the card is clamped outside the inner sliding frame to limit the sliding frame, and the position of the electric grinding wheel can be fixed during grinding without the need for the staff to constantly push with force.

[0016] Fourth, in this lens positioning, clamping and grinding device for glasses production, when the limiting folding plate drives the round block and the sliding frame to slide towards the positioning groove side, the sliding frame squeezes the second spring, causing the second spring to deform and contract. After the lens grinding is completed, the staff rotates the card to release the card clamped on the outer shell. At this time, the first spring and the second spring rebound and reset, and the electric grinding wheels installed on the sliding frame move back accordingly, facilitating the staff to take out the ground lens.

[0017] V. The lens positioning, clamping and grinding equipment for glasses production mounts the clamping assembly above the base through the support bending frame and the base frame. After the staff clamps the lens between the two side pushing and clamping parts, they rotate the mounting rod so that the mounting rod moves within the arc-shaped plate, making the cushion block installed at the bottom of the mounting rod fit above the lens. The cushion block is made of rubber material. It cooperates with the pushing and clamping parts to clamp the side of the lens from multiple positions, and reduces the vibration of the lens during grinding, playing a role in assisting the synchronous clamping of the pushing and clamping parts for positioning and clamping, thereby improving the stability of the lens during grinding and using flexible clamping material to avoid wear on the side of the lens during grinding.

The support bent frames 61 and the base frame 62 erect the clamping component 8 above the base 1. After the staff clamps the lens between the two side pusher clips 81, rotate the installation rod 67 so that the installation rod 67 moves in the arc-shaped plate 64, so that the cushion block 66 installed at the bottom of the installation rod 67 fits above the lens. The cushion block 66 is made of rubber material. Through the cooperation of the cushion block 66 and the pusher clip 81, the side of the lens is clamped at multiple points, and the vibration of the lens is reduced during grinding, playing a role in assisting the synchronous clamping of the pusher clip 81 for positioning and clamping, thereby improving the stability of the lens during grinding, and using flexible clamping material to avoid wear on the side of the lens during grinding.

[0022] The support bent frame 61 is fixedly installed in the middle of the outer surface of the sliding frame 41, there are two connection blocks 63, and both internal parts of the two connection blocks 63 are slidably connected to the clamping component 8.

[0023] The clamping assembly 8, there are two clamping assemblies 8, and both of the two clamping assemblies 8 are slidably installed inside the support assembly 6. During the production of glasses, the staff first place two symmetric glasses lenses inside the support assembly 6, and then adjust the positions of the clamping assemblies 8 on both sides of the support assembly 6 according to the size of the lenses, so that the clamping assemblies 8 clamp on both sides of the lenses to position the lenses before grinding. Then the staff adjust the positions of the electric grinding wheels 7 on both sides of the adjusting assembly 4, so that the electric grinding wheels 7 move to fit the lenses. Then the staff start the electric grinding wheels 7 to make the electric grinding wheels 7 rotate and grind the two lenses at the same time, thereby improving the lens processing efficiency.

[0024] The clamping assembly 8 includes a limit push frame 82. A connecting plate 83 is fixedly installed at the middle of the outer surface of the limit push frame 82. A push clamp 81 is fixedly installed on the outer surface of the connecting plate 83. The push clamp 81 penetrates through the connecting block 63 and extends to the outside. The push clamp 81 is slidably installed inside the connecting block 63. The staff push the limit push frame 82 from both sides, so that the limit push frame 82 drives the push clamp 81 to slide inside the connecting block 63. At this time, the two push clamps 81 displace from both sides to the middle and symmetrically clamp the two lenses between the push clamps 81. The limit push frame 82 is stuck on the outside of the connecting block 63, which can stably position and clamp the curved lenses on the premise of avoiding lens damage and prevent the lenses from deviating from the position during grinding.

[0025] The adjusting assembly 4 includes an inner sliding frame 42. Sliding frames 41 are slidably installed at both ends inside the inner sliding frame 42. There are two sliding frames 41, and the two sliding frames 41 are symmetrically arranged with the inner sliding frame 42 as the center. Round blocks 43 are fixedly installed at the bottoms of the sliding frames 41. A collar 46 is fixedly installed at the middle of the bottom of the inner sliding frame 42. An adjusting rod 47 is movably installed inside the collar 46. A card 48 is rotatably installed on the outer surface of the adjusting rod 47. A first spring 45 is sleeved on the surface of the adjusting rod 47 near the card 48. The first spring 45 is adapted to be squeezed with the collar 46. A limit folding plate 44 is fixedly installed on the surface of the adjusting rod 47 away from the card 48. The limit folding plate 44 is adapted to the round block 43. After clamping and positioning the lenses, the staff pull the adjusting rod 47 outwards. At this time, the adjusting rod 47 slides inside the collar 46. The first spring 45 sleeved on the surface of the adjusting rod 47 is affected by the displacement of the adjusting rod 47 and is squeezed with the collar 46 and deformed. The limit folding plate 44 installed on the outside of the adjusting rod 47 slides towards each other with the two round blocks 43 as the adjusting rod 47 moves, so that the sliding frames 41 connected to the round blocks 43 slide towards each other, thereby adjusting the positions of the sliding frames 41 inside the inner sliding frame 42, so that the electric grinding wheels 7 installed above the sliding frames 41 move towards each other to grind the lenses.

[0026] The sliding frame 41 is fixedly installed at the bottom of the electric grinding wheel 7. Both sides of the outer surface of the sliding frame 41 are fixedly connected to the clamping frame 2 and the support assembly 6. The sliding frame 41 is fixedly installed between the opposite surfaces of the support plate 3 through the clamping frame 2. After the card 48 installed on the surface of the adjusting rod 47 is pulled to the outside of the inner sliding frame 42, the worker rotates the card 48 so that the card 48 is clamped on the outside of the inner sliding frame 42 to limit the position of the sliding frame 41, which can fix the position of the electric grinding wheel 7 during grinding without the need for manual continuous pushing force.

[0027] The inner sliding frame 42 includes an inner support cavity 422. A second spring 421 is installed inside the inner support cavity 422. The outer surface of the inner support cavity 422 is sleeved with a housing 423. Positioning grooves 424 are opened on both sides of the outer surface of the housing 423.

[0028] Second embodiment, on the basis of the first embodiment, please refer to Figures 5 to 6 As shown, the pusher clip 81 includes a sliding piece 811. A protective piece 814 is fixedly installed on the outer surface of the sliding piece 811. A clamping pad 812 is fixedly installed in the middle of the outer surface of the protective piece 814. A clamping groove 813 is opened inside the clamping pad 812. The lens is clamped inside the clamping groove 813. The clamping pad 812 outside the clamping groove 813 is made of a flexible material. Since the shapes of the spectacle frames are diverse and the lenses themselves have a curvature, when the two lenses are placed in the clamping groove 813, the flexible clamping pad 812 is deformed under the influence of the lens curvature and fits against the side of the lens according to the lens curvature. Moreover, the flexible clamping pad 812 enhances the friction force when clamping the lens, realizing the simultaneous positioning and clamping of the left and right lenses, avoiding lens damage, and effectively preventing the lens from running off during the grinding process.

[0029] The sliding piece 811 is fixedly installed on the outer surface of the connecting plate 83. The sliding piece 811 is slidably installed inside the connecting block 63. The clamping pad 812 and the clamping groove 813 are set to be arc-shaped to match the arc-shaped lens. When the electric grinding wheel 7 grinds the lens, the protective piece 814 arranged outside the clamping pad 812 blocks the flying dust and debris to limit the falling range of the dust and debris and reduce the scattering range of the dust and debris.

[0030] Third embodiment, on the basis of the first and second embodiments, please refer to Figures 8 to 9As shown, a chute is provided between the inner support cavity 422 and the outer shell 423. The second spring 421 is fixedly installed between the opposite surfaces of the sliding frame 41. The sliding frame 41 is slidably installed inside the chute, and the round block 43 is adapted to the positioning groove 424. When the limit folding plate 44 drives the round block 43 and the sliding frame 41 to slide towards the positioning groove 424, the sliding frame 41 squeezes the second spring 421, causing the second spring 421 to deform and contract. After the lens grinding is completed, the staff rotates the card 48 to release the card 48 stuck on the outer shell 423. At this time, the first spring 45 and the second spring 421 rebound and reset, and the electric grinding wheel 7 installed on the sliding frame 41 moves and resets accordingly, facilitating the staff to take out the ground lens.

[0031] The staff pushes the limit push frame 82 from both sides, causing the limit push frame 82 to drive the push clamp 81 to slide within the connecting block 63. At this time, the two push clamps 81 displace from both sides towards the middle and symmetrically clamp the two lenses between the push clamps 81. The limit push frame 82 is stuck on the outside of the connecting block 63, which can stably position and clamp the lens with a curvature on the premise of avoiding lens damage, preventing the lens from shifting during grinding.

[0032] The lens is clamped inside the clamping groove 813. The clamping pad 812 outside the clamping groove 813 is made of a flexible material. Due to the diverse shapes of the frames and the curvature of the lens itself, when the two lenses are placed in the clamping groove 813, the flexible clamping pad 812 deforms under the influence of the lens curvature and fits against the side of the lens according to the lens curvature. Moreover, the flexible clamping pad 812 enhances the friction when clamping the lens, achieving simultaneous positioning and clamping of the left and right lenses, avoiding lens damage, and effectively preventing the lens from running off during grinding.

[0033] When the electric grinding wheel 7 grinds the lens, the protective sheet 814 provided outside the clamping pad 812 blocks the flying dust and debris, restricting the range of dust and debris falling and reducing the scattering range of dust and debris.

[0034] The support bent frame 61 and the base frame 62 mount the clamping assembly 8 above the base 1. After the staff clamps the lens between the two push clamps 81, the mounting rod 67 is rotated so that the mounting rod 67 moves within the arc-shaped plate 64, causing the cushion block 66 installed at the bottom of the mounting rod 67 to fit above the lens. The cushion block 66 is made of rubber material. The cushion block 66 and the push clamp 81 cooperate to clamp the side of the lens from multiple positions, and reduce the vibration of the lens during grinding, playing a role in assisting the synchronous clamping of the push clamp 81 for positioning and clamping, thereby improving the stability during lens grinding and avoiding wear on the side of the lens during grinding using flexible clamping materials.

[0035] During use, in the process of glasses production, the staff first place two symmetrical glasses lenses in the support assembly 6, and then adjust the positions of the clamping assemblies 8 on both sides of the support assembly 6 according to the size of the lenses, so that the clamping assemblies 8 clamp on both sides of the lenses to position the lenses before grinding. Then, the staff adjust the positions of the electric grinding wheels 7 on both sides of the adjusting assembly 4, so that the electric grinding wheels 7 move to fit the lenses. Then, the staff start the electric grinding wheels 7 to make the electric grinding wheels 7 rotate while grinding the two lenses, thereby improving the lens processing efficiency.

[0036] After the lenses are clamped and positioned, the staff pull the adjusting rod 47 outwards. At this time, the adjusting rod 47 slides in the collar 46. The first spring 45 sleeved on the surface of the adjusting rod 47 is deformed by the displacement of the adjusting rod 47 and is squeezed by the collar 46. The limiting folding plates 44 installed on the outside of the adjusting rod 47 move towards each other along with the adjusting rod 47 to slide the round blocks 43 on both sides, so that the sliding frames 41 connected to the round blocks 43 slide towards each other, thereby adjusting the positions of the sliding frames 41 in the inner sliding frames 42, so that the electric grinding wheels 7 installed above the sliding frames 41 move towards each other to grind the lenses.

[0037] After the card 48 installed on the surface of the adjusting rod 47 is pulled to the outside of the inner sliding frame 42, the staff rotate the card 48 so that the card 48 is stuck on the outside of the inner sliding frame 42 to limit the sliding frame 41, and the position of the electric grinding wheel 7 can be fixed during grinding without the need for manual continuous pushing.

[0038] When the limiting folding plates 44 drive the round blocks 43 and the sliding frames 41 to slide towards the positioning groove 424, the sliding frames 41 squeeze the second spring 421, causing the second spring 421 to deform and contract. After the lenses are ground, the staff rotate the card 48 to release the card 48 stuck on the outer shell 423. At this time, the first spring 45 and the second spring 421 rebound and reset, and the electric grinding wheels 7 installed on the sliding frames 41 move and reset accordingly, so that it is convenient for the staff to take out the ground lenses.
