Description

Technical Field

[0001] The utility model relates to the technical field of lens production equipment, in particular to an edge grinding mechanism for lens production. Background Art

[0002] During lens processing, the lens needs to be edged in order to facilitate positioning during subsequent lens surface processing. Therefore, lens edge grinding is the most important process in lens processing. The higher the accuracy of lens edge grinding, the more accurate the lens processing accuracy can be guaranteed in the later stage. Moreover, edge grinding is the last processing step in lens cold processing. If the lens is scrapped during the edge grinding process, all the previous processes: cutting, rough grinding, fine grinding, polishing, etc. will be wasted, resulting in great waste.

[0003] However, the existing edge grinding devices mostly adopt a horizontal grinding method when in use, which cannot well grind the edges of lens bodies of different specifications, resulting in poor friction accuracy. Therefore, it is necessary to provide a new lens processing and edge grinding device to solve the above technical problems.

[0004] In the published Chinese patent application, the publication number is: CN220240993U, and the patent name is: A lens processing and edging device, including a support plate and a grinding box, the grinding box is fixedly mounted on the top of the support plate; a first motor, the first motor is fixedly mounted on one side outer wall of the grinding box; a slide groove, the slide groove is opened on the top inner wall of the grinding box; a bidirectional screw, the bidirectional screw is rotatably mounted in the slide groove, and the end of the bidirectional screw extending outside the grinding box is fixedly connected to the output shaft of the first motor; two sliders, both of the two sliders are slidably mounted in the slide groove, and the two sliders are threadedly connected to the bidirectional screw; an edging mechanism, the edging mechanism is arranged in the grinding box. This existing technology drives the bidirectional screw to start rotating through the output shaft of the first motor, thereby driving the two sliders to move to the appropriate position in the slide groove. The movement positioning process is easy to operate and can be adjusted according to different lens specifications. The positioning plate is driven downward by the rotating motor in the fixed plate. The angle adjustment process is relatively simple and easy to operate. The friction wheel is driven to start rotating by the output shaft of the grinding motor, so that the friction wheel can grind the edge of the lens more finely.

[0005] While this prior art can solve the aforementioned problems, it has certain limitations in its implementation. This prior art clamps and secures the lens using two extrusion blocks to hold the two sides of the lens. However, when the lens is placed between the two extrusion blocks, it is not possible to effectively ensure that the center of the lens and the centers of the two extrusion blocks are aligned on the same central axis, which can easily cause uneven wear of the lens during the polishing process.

[0006] To sum up, the problems existing in the prior art are: it is impossible to effectively ensure that the center of the lens and the centers of the two extrusion blocks are on the same central axis, which can easily cause uneven grinding of the lens during the grinding process. In order to solve the problems existing in the prior art, this case is specially proposed to solve them. Utility Model Content

[0027] See also Figs. 1 to 3 The utility model provides a technical solution: an edging mechanism for lens production, including an equipment box 1 and a water tank 2. A box door 3 is slidingly provided on one side wall of the equipment box 1, and a glass window is provided on the box door 3. A second cylinder 9 is fixedly installed on the equipment box 1, and the output shaft end of the second cylinder 9 is fixedly connected to the box door 3.

[0028] The second cylinder 9 is used to drive the box door 3 to slide on the equipment box 1, thereby opening or closing the box door 3.

[0029] The water tank 2 is fixedly installed below the equipment box 1. A workbench 17 is slidably provided inside the equipment box 1. A grinding component and a first driving component are provided inside the equipment box 1. A second driving component and a straightening component are provided on the workbench 17.

[0030] The workbench 17 is used to support the lens and drive its movement within the equipment box 1. The polishing component is used to polish the edge of the lens. The first and second drive components are used to clamp and secure the lens above and below, exposing the lens edge to facilitate polishing. The straightening component is used to straighten the lens, aligning the center of the lens with the centers of the first and second drive components to prevent uneven wear of the lens due to the lens not being properly centered.

[0031] A placement position is provided in the middle of the workbench 17 , and sliding grooves 21 are provided at both ends of the workbench 17 and on both sides of the placement position.

[0032] The straightening component includes two clamping assemblies, each comprising a screw 22, a slider 20, a clamping plate 25, and a gear 11. Both ends of the screw 22 are rotatably connected to the workbench 17. The slider 20 is slidably connected to the workbench 17 via a slide 21, and the lower end of the slider 20 is threadedly connected to the screw 22. The clamping plate 25 is provided on a side wall of the upper end of the slider 20, and the gear 11 is fixedly mounted on one end of the screw 22. Two parallel racks 10 are embedded and fixedly connected to the inner bottom wall of the equipment box 1. The gears 11 in the two clamping assemblies mesh with the two racks 10, respectively. A first cylinder 8 is fixedly mounted on the inner side wall of the equipment box 1, and the output shaft end of the first cylinder 8 is fixedly connected to the workbench 17.

[0033] Among them, the first cylinder 8 is used to drive the workbench 17 to slide on the bottom wall of the equipment box 1. After the first cylinder 8 is activated, it pulls or pushes the workbench 17 into or out of the center of the equipment box 1. When the lens is placed at the placement position on the workbench 17, the first cylinder 8 drives the workbench 17 to move toward the center of the equipment box 1. Because the gear 11 in the two clamping assemblies is engaged with the rack 10, the gear 11 rotates during the movement of the workbench 17. The gear 11 drives the screw 22 to rotate on the workbench 17, and the screw 22 drives the slider 20 threadedly connected thereto to move. The sliders 20 of the two clamping assemblies approach each other, and the sliders 20 drive the clamps 25 to move, which means that the clamps 25 in the two clamping assemblies can be brought closer together. The two clamps 25 push the lens to the center of the placement position, and the two clamps 25 also clamp the lens.

[0034] Specifically, a slide rod 23 is provided at the upper end of the slider 20 for transverse sliding. One end of the slide rod 23 is fixedly connected to the clamping plate 25 . A spring 24 is sleeved on the slide rod 23 , and the spring 24 is located between the clamping plate 25 and the slider 20 .

[0035] The spring 24 is used for buffering the clamping plate 25, preventing the clamping plate 25 from directly contacting the lens and damaging the lens. The sliding rod 23 is used for guiding the clamping plate 25 to move in a straight line.

[0036] Specifically, the second driving component includes a third cylinder 13 and a rubber disc 4.

The bottom wall of the equipment box 1 is provided with a first groove 12, and the lower part of the cylinder barrel of the third cylinder 13 penetrates the first groove 12.

[0037] The second driving component is used for supporting the lens from below. The second driving component is located on the same longitudinal central axis as the placing position. The starting position of the rubber disc 4 in the second driving component is located at the placing position, and the rubber disc 4 is used for supporting the lower surface of the lens. The clamping plate 25 in the two clamping assemblies pushes the center of the lens to be located at the central axis of the rubber disc 4, so as to ensure that the lens is consistent with the central axis of the rubber disc 4. The third cylinder 13 is used for driving the rubber disc 4 to move up and down, and the rubber disc 4 drives the lens to move up and down.

[0038] Specifically, the first driving component includes a fifth electric cylinder 16 and a servo motor 5. The cylinder barrel end of the fifth electric cylinder 16 is fixedly installed on the inner top wall of the equipment box 1. The output shaft end of the servo motor 5 is fixedly installed on the output shaft end of the fifth electric cylinder 16. The output shaft end of the servo motor 5 is also provided with a rubber disc 4.

[0039] The first driving component is used for fixing the upper surface of the lens and driving the lens to rotate. The first driving component cooperates with the second driving component to clampingly fix the lens, so as to realize clamping and fixing of the upper and lower surfaces of the lens. The fifth electric cylinder 16 is used for pushing the servo motor 5 and the rubber disc 4 to be close to the lens. The rubber disc 4 in the first driving component cooperates with the rubber disc 4 in the second driving component to clampingly fix the upper and lower parts of the lens, and at the same time, the lens can be driven to move up and down. The servo motor 5 is used for driving the lens to rotate. After the servo motor 5 is started, the rubber disc 4 is driven to rotate, and the rubber disc 4 drives the lens to rotate.

[0040] Specifically, the polishing component includes a support block 7, a polisher 6, a water pump 14, and a fourth cylinder 15. The support block 7 is slidingly arranged on the inner bottom wall of the equipment box 1. The fourth cylinder 15 is fixedly installed on the inner side wall of the equipment box 1, and the output shaft end of the fourth cylinder 15 is fixedly connected with the support block 7. The polisher 6 and the water pump 14 are both fixedly installed on the support block 7. The medium inflow end of the water pump 14 is communicated with the water tank 2 through a conduit 26. The medium outflow end of the water pump 14 faces the polishing part of the polisher 6.

[0041] Among them, the grinder 6 is used to grind the lens. The water pump 14 is used to extract water from the water tank 2 and use the water to rinse the lens during grinding to avoid dust generation during grinding. After the grinder 6 is started, the grinding part (grinding stone) of the output shaft of the grinder 6 rotates at high speed. The servo motor 5 drives the rubber disc 4 to rotate, and the rubber disc 4 drives the lens to rotate at high speed. The fifth electric cylinder 16 and the third cylinder 13 cooperate to push or pull the lens up and down, so that the lens and the grinding part of the grinder 6 are at the same height. After the fourth cylinder 15 is started, it pushes the support block 7 to move close to the lens, so that the grinding part of the grinder 6 contacts the edge of the lens and grinds the edge of the lens.

[0042] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
