Description

Technical Field

[0001] This utility model relates to an optical lens processing equipment, specifically to an edge grinder for optical lens processing. Background Technology

[0002] Optical glass is made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula. This mixture is melted at high temperature in a platinum crucible and ultrasonically stirred to remove air bubbles. Then, it undergoes a long, slow cooling process to prevent internal stress in the glass block. After cooling, the glass block must be measured with optical instruments to check its purity, transparency, uniformity, refractive index, and dispersion to ensure they meet specifications. Qualified glass blocks are then heated and pressed to form optical lens blanks.

[0003] After optical glass is manufactured, there are often a lot of burrs on the sides. In order for the optical glass to be installed and used normally in the later stage, the burrs on the sides need to be removed. Therefore, an edge grinder for optical lens processing is needed.

[0004] Currently, optical lens edging machines typically clamp and fix the lens before rotating it, and then use a grinding wheel to grind the rotating lens. However, the grinding wheel can only move horizontally and cannot be adjusted in angle, so it is not very comprehensive and flexible in grinding the side edges of the lens. Utility Model Content

[0005] The main objective of this disclosure is to provide an edge grinder for optical lens processing, so as to effectively solve the problems raised by the inventors in the background art mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An edging tool for optical lens processing includes a housing. A support column is rotatably mounted at the bottom of the housing, and a support plate is fixedly mounted at the upper end of the support column. A connecting plate is rotatably mounted at the upper end of the housing, and a hydraulic rod is fixedly mounted at the lower end of the connecting plate. A clamping block is fixedly mounted at the output end of the hydraulic rod. A rotary motor is fixedly mounted at the top of the housing, and the output end of the rotary motor is fixedly connected to the rotating shaft of the connecting plate. Electric push rods are fixedly mounted on both the left and right sides of the housing, and each push rod is fixedly mounted with a limiting rod. Vertical plates are fixedly mounted at the telescopic ends of both electric push rods. The two vertical plates are slidably connected to the limiting rods on both sides, and the limiting rods pass through the vertical plates. The two vertical plates are close to each other. Each side is equipped with a lifting plate that can be raised and lowered. Two U-shaped connecting blocks are movable on one side of each lifting plate, and rotating rods are rotatably installed within each connecting block. T-shaped rotating plates are fixedly installed on each of the rotating rods. Rotary motors are fixedly installed on each of the two U-shaped connecting blocks, and their output ends are fixedly connected to the two rotating rods.

[0008] Preferably, lifting screws are rotatably installed between the upper and lower inner walls of the two vertical plates, and slide rods are fixedly installed on both. Openings are opened on the side of the two vertical plates that are close to each other. Lifting blocks are threaded onto the two lifting screws, and the two lifting blocks are slidably connected to the slide rods on both sides. The two lifting plates are fixedly installed on the side of the two lifting blocks that are close to each other. By rotating the lifting screws, the lifting blocks can slide and rise on the slide rods, thereby allowing the grinding wheel to be adjusted for use.

[0009] Preferably, a servo motor is fixedly installed near the lower end of each of the two vertical plates. The output ends of the two servo motors are respectively fixedly connected to the shafts of the two lifting screws, and the lifting screws are controlled to rotate in both directions by the servo motors.

[0010] Preferably, a translation screw is rotatably installed between the front and rear inner walls of both lifting plates, and a slide rod two is fixedly installed on each. An opening is formed on the side of each lifting plate that is close to the other. A translation block is threaded onto each of the two translation screws, and the two translation blocks are slidably connected to the slide rods two on both sides. Two U-shaped connecting blocks are fixedly installed on the side of each translation block that is close to the other. By rotating the translation screws, the translation blocks, carrying the U-shaped connecting blocks, can slide on the slide rods two, thereby allowing the grinding wheel to move back and forth. This can be used for grinding square optical lenses.

[0011] Preferably, servo motors are fixedly installed on the front sides of both lifting plates, and the output ends of the two servo motors are respectively fixedly connected to the rotating shafts of the two translation screws. The translation screws can be controlled to rotate in both directions by the servo motors.

[0014] In this application, the push rod is equipped with a U-shaped connecting block, a rotating rod, and a T-shaped rotating plate. When using the grinding wheel, the rotating rod can be driven to rotate by a rotary motor according to the position of the burrs on the side of the lens. This allows the T-shaped rotating plate to rotate, thereby adjusting the angle of the grinding wheel for use. This provides more comprehensive grinding of the lens side and is more flexible in use.

[0021] An edging tool for optical lens processing includes a housing 1. A support column 2 is rotatably mounted at the bottom of the housing 1. A support plate 3 is fixedly mounted at the upper end of the support column 2. A connecting plate 4 is rotatably mounted at the upper end of the housing 1. A hydraulic rod 5 is fixedly mounted at the lower end of the connecting plate 4. A clamping block 6 is fixedly mounted at the output end of the hydraulic rod 5. A rotary motor 7 is fixedly mounted at the top of the housing 1. The output end of the rotary motor 7 is fixedly connected to the rotating shaft of the connecting plate 4. Electric push rods 8 are fixedly mounted on both the left and right sides of the housing 1, and limit rods 9 are fixedly mounted on each. Vertical plates 10 are fixedly mounted on the telescopic ends of both electric push rods 8. The two vertical plates 10 are slidably connected to the limit rods 9 on both sides. The limit rods 9 penetrate the vertical plates 10. The two vertical plates 10 can be raised and lowered when close to each other on one side. The two lifting plates 15 are movable and can be positioned close to each other. They are equipped with U-shaped connecting blocks 20. Rotating rods 21 are rotatably installed in both connecting blocks. T-shaped rotating plates 22 are fixedly installed on both rotating rods 21. Rotary motors 23 are fixedly installed on both U-shaped connecting blocks 20. The output ends of the two rotary motors 23 are fixedly connected to the two rotating rods 21. Connecting frames 24 are fixedly installed on both T-shaped rotating plates 22 close to each other. Rotary motors 25 are fixedly installed in both connecting frames 24 close to each other. Connecting pieces 26 are rotatably installed on both connecting frames 24 close to each other. Grinding wheels 27 are detachably installed in both connecting pieces 26. The output ends of the two rotary motors 25 are fixedly connected to the rotating shafts of the two connecting pieces 26 respectively.

[0022] Specifically, lifting screws 11 are rotatably installed between the upper and lower inner walls of the two vertical plates 10, and slide rods 12 are fixedly installed on both. Openings are opened on the side of the two vertical plates 10 that are close to each other. Lifting blocks 13 are threadedly installed on the two lifting screws 11, and the two lifting blocks 13 are slidably connected to the slide rods 12 on both sides. Two lifting plates 15 are fixedly installed on the side of the two lifting blocks 13 that are close to each other. By rotating the lifting screws 11, the lifting blocks 13 can slide and lift the lifting plates 15 on the slide rods 12, thereby allowing the grinding wheel 27 to be adjusted for lifting and use.

[0023] Specifically, servo motors 14 are fixedly installed near the lower end of the two vertical plates 10. The output ends of the two servo motors 14 are fixedly connected to the rotating shafts of the two lifting screws 11, and the lifting screws 11 are controlled to rotate in both directions by the servo motors 14.

[0024] Specifically, translation screws 16 are rotatably installed between the front and rear inner walls of the two lifting plates 15, and slide rods 17 are fixedly installed on both. Openings are formed on the adjacent sides of the two lifting plates 15. Translation blocks 18 are threaded onto the two translation screws 16, and the two translation blocks 18 are slidably connected to the slide rods 17 on both sides. Two U-shaped connecting blocks 20 are fixedly installed on the adjacent sides of the two translation blocks 18. By rotating the translation screws 16, the translation blocks 18, carrying the U-shaped connecting blocks 20, can slide on the slide rods 17, thereby allowing the grinding wheel 27 to move back and forth. This can be used for grinding square optical lenses.

[0025] Specifically, servo motors 19 are fixedly installed on the front of both lifting plates 15. The output ends of the two servo motors 19 are fixedly connected to the rotating shafts of the two translation screws 16, respectively. The translation screws 16 can be controlled to rotate forward and backward by the servo motors 19.

[0026] Specifically, two bottom grooves 28 are provided in the lower end of the outer casing 1, and each bottom groove 28 is equipped with a dust collection box 29. The dust collection box 29 can collect the debris generated during polishing, preventing it from being difficult to clean later.

[0027] The working principle of this utility model is as follows: First, the optical lens is placed on the support plate 3. The hydraulic rod 5 pushes the clamping block 6 down to hold the lens. If the lens is round, the rotating motor 7 drives the connecting plate 4 to rotate, thus rotating the lens. If the lens is square, rotation is not required. When the lens is square, the two push rods 8 can push the two vertical plates 10 inward to make the two grinding wheels 27 grind both sides of the square lens simultaneously. Before using the grinding wheels 27, the rotating motor 3 25 drives the grinding wheels 27 to rotate. The rotating grinding wheels 27 are brought into contact with the side of the lens to begin grinding. During grinding, the servo motor 1 can be used to control the rotation. 4. The lifting screw 11 is rotated, causing the lifting block 13 to slide on the sliding rod 12 with the lifting plate 15, thereby adjusting the height of the grinding wheel 27. However, the translation screw 16 is rotated by the servo motor 29, causing the translation block 18 to slide on the sliding rod 17 with the U-shaped connecting block 20, thereby allowing the grinding wheel 27 to be moved back and forth. According to the position of the burrs on the side of the lens, the rotating rod 21 is rotated by the rotary motor 23, thereby rotating the T-shaped rotating plate 22, so as to adjust the tilt angle of the grinding wheel 27. The debris generated during grinding will fall into the dust collection box 29 for collection.
