Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical glass processing technology, and in particular to an optical glass cutting device with anti-scratch function. Background Technology
[0002] Optical glass is glass that can alter the direction of light propagation and change the relative spectral distribution of ultraviolet, visible, or infrared light. In a narrow sense, optical glass refers to colorless optical glass; in a broader sense, it also includes colored optical glass, laser glass, quartz optical glass, radiation-resistant glass, ultraviolet-infrared optical glass, fiber optic glass, acousto-optic glass, magneto-optic glass, and photochromic glass. Optical glass requires extremely high processing precision, necessitating the use of appropriate cutting equipment.
[0003] When cutting optical glass, the cutting device first places the glass on a vacuum adsorption platform and starts the vacuum pump to firmly fix the glass in place. Then, the tool cooling system is activated, the cutting tool is turned on, and cutting is performed according to the preset cutting path. During the cutting process, a protective cover prevents debris from flying, and the cooling system ensures that the temperature of the tool and the glass remains stable.
[0004] In the prior art, some cutting devices use protective covers to prevent debris from flying. The protective covers are usually fixed to the outside of the cutting head, but the protection range cannot be adjusted according to the thickness of the glass being cut, which will result in incomplete protection. To address this issue, an optical glass cutting device with anti-scratch function is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an optical glass cutting device with anti-scratch function, which aims to improve the problem that the protection range cannot be adjusted according to the thickness of the glass being cut in the prior art, resulting in incomplete protection.
[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0007] An optical glass cutting device with scratch-resistant function includes an operating table. Support frames are fixedly connected to the left and right sides of the operating table. A control head is slidably connected to the front end of the support frames. A cutting head is fixedly connected to the drive end of the control head. A connecting plate is slidably connected to the outside of the cutting head. Multiple fixed columns are slidably connected inside the connecting plate. A protective cover is fixedly connected to the bottom of the multiple fixed columns. A limit component is provided on the outside of the fixed columns. The limit component can reset the protective cover. A fixing component is provided on the top of the operating table. The fixing component can prevent the glass from shifting during processing.
[0008] As a further description of the above technical solution:
[0009] The limiting component includes a limiting plate, the bottom of which is fixedly connected to the top of the fixing post, and a spring is sleeved on the outside of the fixing post.
[0010] As a further description of the above technical solution:
[0011] One end of the spring is fixedly connected to the bottom of the connecting plate, and the other end of the spring is fixedly connected to the top of the protective cover.
[0012] As a further description of the above technical solution:
[0013] The cutting head is slidably connected to the inside of the protective cover, and the outside of the limiting plate is in contact with the top of the connecting plate;
[0014] As a further description of the above technical solution:
[0015] The top of the operating table is fixedly connected to a guide shaft, and a placement plate is slidably connected to the outside of the guide shaft. The placement plate has multiple cavities inside.
[0016] As a further description of the above technical solution:
[0017] The fixing component includes a second spring, one end of which is fixedly connected to one side of the inner wall of the cavity, and the other end of which is fixedly connected to a second limiting plate. A stop post is fixedly connected to the side of the second limiting plate away from the second spring.
[0018] As a further description of the above technical solution:
[0019] The outer side of the limiting plate 2 is slidably connected to the inner wall of the cavity, and the outer side of the abutment is slidably connected to the inner wall of the cavity;
[0020] As a further description of the above technical solution:
[0021] Multiple vacuum suction cups are fixedly connected to the top of the placement plate, and the bottom of the protective cover is in contact with the top of the placement plate.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, a protective cover is set on the outside of the cutting head. As the cutting head moves, the protective cover comes into contact with the glass. Then the cutting head processes the glass. At this time, the protective cover will push the fixed column upward and slide inside the connecting plate. At the same time, the spring is compressed and the spring pair generates a reaction force on the protective cover, so that the protective cover and the glass are in closer contact. It can elastically adapt to the protection of glass of different thicknesses.
[0024] 2. In this utility model, by placing the glass inside the placement plate, the glass presses against the abutment, pushing the limiting plate to compress the second spring. The compression of the second spring will generate a reaction force on the limiting plate, so that the abutment presses and fixes the glass. At the same time, the vacuum suction cup further fixes the glass, which can prevent the glass from shaking during cutting and ensure the accuracy of cutting. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1 to 3This utility model provides an embodiment of an optical glass cutting device with scratch-resistant function, including an operating table 1. The operating table 1 is the basic structure of the entire cutting device, providing support and mounting positions for other components. Support frames 2 are fixedly connected to the left and right outer sides of the operating table 1, providing stable support and a sliding track for the control head 3. The control head 3 is slidably connected to the front end of the support frame 2, and is a key control component for the cutting operation. By sliding left and right on the support frame 2, the lateral cutting position can be adjusted to accommodate optical glass of different sizes and cutting requirements.
[0034] The drive end of the control head 3 is fixedly connected to the cutting head 4, which is a component that directly cuts optical glass and can adapt to the hardness and brittleness of optical glass. The cutting head 4 is externally slidably connected to a connecting plate 5, and multiple fixed posts 6 are internally slidably connected to the connecting plate 5, providing sliding channels and support for the fixed posts 6. Its internal sliding structure design ensures that the fixed posts 6 can slide smoothly up and down, while ensuring a firm connection with other components.
[0035] Multiple fixed posts 6 are fixedly connected to the bottom of a protective cover 8. During the cutting process, the protective cover 8 is pushed upward by the fixed posts 6. The fixed posts 6 need to have sufficient strength and rigidity to withstand this force and ensure the sliding fit accuracy with the connecting plate 5. A limit component is provided on the outside of the fixed posts 6. The limit component can reset the protective cover 8. During cutting, it contacts the outside of the glass and can move with the cutting head 4 to block debris. The limit component includes a limit plate 7. The bottom of the limit plate 7 is fixedly connected to the top of the fixed post 6. A spring 9 is sleeved on the outside of the fixed post 6. The limit plate 7 limits the fixed post 6. When the spring 9 is compressed, it prevents the fixed post 6 from being pushed down excessively, ensuring that the protective cover 8 can accurately reset under the reaction force of the spring 9 and maintain close contact with the glass.
[0036] One end of spring 9 is fixedly connected to the bottom of connecting plate 5, and the other end of spring 9 is fixedly connected to the top of protective cover 8. During the cutting process, when protective cover 8 is pushed upward by the fixed post 6, spring 9 is compressed and stores elastic potential energy. When the cutting force disappears, spring 9 releases its elastic potential energy, pushing protective cover 8 downward to reset, making it more tightly contacted with the outside of the glass. The outside of the cutting head 4 is slidably connected to the inside of protective cover 8, and the outside of limiting plate 7 is in contact with the top of connecting plate 5.
[0037] Reference Figures 4 to 5The top of the operating table 1 is equipped with a fixing component to prevent the glass from shifting during processing. A guide shaft 10 is fixedly connected to the top of the operating table 1, and a placement plate 11 is slidably connected to the outside of the guide shaft 10. The placement plate 11 can slide back and forth via the guide shaft 10, thereby adjusting the front-to-back position of the glass on the operating table 1. The guide shaft 10 must ensure sufficient straightness and surface smoothness to ensure the stability and accuracy of the placement plate 11 during sliding. The bottom of the protective cover 8 contacts the top of the placement plate 11, and its front-to-back position can be adjusted by sliding it along the guide shaft 10.
[0038] The interior has multiple cavities 12 for accommodating other components of the fixing assembly. The fixing assembly includes a second spring 13. One end of the second spring 13 is fixedly connected to one side of the inner wall of the cavity 12, and the other end of the second spring 13 is fixedly connected to a second limiting plate 14, providing installation space for the second limiting plate 14 and the second spring 13 and other fixing assembly components.
[0039] The inner wall of cavity 12 must be sufficiently smooth to ensure that the limiting plate 14 can slide smoothly inside it. A stop post 15 is fixedly connected to the side of the limiting plate 14 away from the spring 13. When the glass is placed on the placement plate 11 and the stop post 15 is pressed, the spring 13 is compressed, storing elastic potential energy. This generates a reaction force on the limiting plate 14, making the stop post 15 contact the glass more tightly, thus providing better fixation for the glass.
[0040] The limiting plate 14 is externally slidably connected to the inner wall of the cavity 12. Under the action of the spring 13, the limiting plate 14 slides within the cavity 12, thereby driving the abutment 15 to fix the glass. The size of the limiting plate 14 must match the inner wall of the cavity 12 to ensure smooth sliding. At the same time, its connection with the abutment 15 must be firm and reliable to ensure that it will not loosen or separate during the force process. The abutment 15 is externally slidably connected to the inner wall of the cavity 12. When the glass is placed on the placement plate 11, the glass will press against the abutments 15 on both sides. The abutments 15 are forced to press the limiting plate 14 to both sides, thereby compressing the spring 13.
[0041] The end of the abutment 15 that contacts the glass may be made of a soft material or have a special surface treatment to prevent scratching the glass. Its shape and size must ensure sufficient contact area with the glass for a stable fixation effect. Multiple vacuum suction cups 16 are fixedly connected to the top of the placement plate 11. These cups generate vacuum suction to adhere the glass to the placement plate 11, further enhancing the stability of the glass during the cutting process. The number and distribution of the vacuum suction cups 16 should be rationally designed according to the size and shape of the glass to ensure uniform and effective adsorption across the entire glass surface. Their suction force must be able to withstand various forces during the cutting process to prevent displacement of the glass.
[0042] Working principle: First, place the operating table 1 in a suitable position, then place the glass on top of the placement plate 11. At the same time, the glass will press against the abutments 15 on both sides. The abutments 15 are forced to press against the limiting plates 14 on both sides. The limiting plates 14 slide inside the cavity 12, causing the spring 13 to be compressed. When the spring 13 is compressed, it will generate a reaction force on the limiting plates 14, making the abutments 15 contact the glass more tightly and fixing the glass. At the same time, the vacuum suction cup 16 will fix the glass a second time. The front and back positions of the placement plate 11 can be adjusted through the guide shaft 10.
[0043] Next, adjust the position of the control head 3 on the support frame 2, start the control head 3, and under the drive of the control head 3, the cutting head 4 moves downward, and the protective cover 8 contacts the outside of the glass. As the cutting head 4 moves continuously, the protective cover 8 is forced to push the fixed column 6 upward, and at the same time the spring 9 is compressed. At this time, the limiting plate 7 will limit the fixed column 6 to prevent it from falling off. Under the reaction force of the spring 9, the protective cover 8 will contact the outside of the glass more tightly, and can block the debris as the cutting head 4 cuts.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
