Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to an optical lens production grinding equipment. Background Technology

[0002] The grinding device is an automated equipment specifically designed for the manufacture of high-precision optical components. By combining a CNC high-rigidity grinding disc, a dynamic pressure feedback system, and a multi-axis precision positioning mechanism, it uses diamond or cerium oxide abrasives to perform nanoscale surface correction and surface polishing on glass, crystal, or resin lens substrates.

[0003] However, because existing grinding devices require fixing the lens during the grinding process, they can only grind a portion of the lens. This often results in insufficient contact between the grinding disc and all parts of the optical lens, leading to uneven grinding, missed areas, and affecting the surface polishing quality of the lens. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an optical lens production grinding apparatus to solve the problem that the grinding apparatus mentioned in the background technology often fails to ensure full contact between the grinding disc and all parts of the optical lens during the grinding process, resulting in uneven grinding, missed parts, and affecting the surface polishing quality of the lens.

[0009] A first motor is disposed on the inner wall of the grinding chamber. A first lead screw is coaxially mounted on the rotor of the first motor, and a moving block is screwed onto the surface of the first lead screw.

[0010] A hydraulic telescopic rod is installed at the bottom of the movable block. A drive motor is installed at the output end of the hydraulic telescopic rod, and a grinding disc is installed at the output end of the drive motor.

[0011] The second motor is located at the rear of the inner cavity of the grinding chamber. The rotor of the second motor is coaxially mounted with a second lead screw. A moving rod is screwed onto the surface of the second lead screw. A mounting bracket is installed at the output end of the moving rod. Clamping plates are provided on both sides of the inner cavity of the mounting bracket.

[0012] Preferably, a third motor is installed on the inner walls of both sides of the mounting frame. The rotor of the third motor is coaxially mounted with a third lead screw. The surface of the third lead screw is screwed with a positioning rod. The inner end of the positioning rod is connected to the surface of the clamping plate. Starting the third motor can drive the third lead screw to rotate, thereby driving the positioning rod to move and causing the clamping plates to move closer to each other.

[0013] Preferably, the upper surface of the clamp is provided with an mounting edge, and the inner wall of the mounting edge is provided with a receiving plate. The clamp will drive the mounting edge to squeeze and position the optical lens, and the receiving plate is used to prevent the optical lens from falling off the bottom of the clamp.

[0014] Preferably, sliders are installed on both the front and back of the positioning rod, and slide rails are installed at corresponding positions of the mounting bracket and the sliders. The sliders are embedded inside the slide rails, allowing the positioning rod to move linearly.

[0015] Preferably, the upper surface of the base is provided with a collection port, and a collection box is installed inside the base, through which the ground powder enters the collection box.

[0016] Preferably, limit blocks are installed on both sides of the mounting frame, and limit grooves are formed on both sides of the inner wall of the grinding chamber. The limit blocks are inserted into the limit grooves, so that the mounting frame can move linearly. Beneficial effects

[0017] Compared with the prior art, the present invention provides an optical lens production and grinding apparatus, which has the following beneficial effects:

[0018] This optical lens production and polishing device includes a first motor that drives a first lead screw to rotate, which in turn moves a moving block, which in turn moves a hydraulic telescopic rod, causing the polishing disc to move left and right. Simultaneously, a second motor drives a second lead screw to rotate, which in turn moves a moving rod, which in turn moves a clamping plate, causing the optical lens clamped in the clamping plate to move back and forth. This ensures that the polishing disc can contact all parts of the optical lens, avoiding any missed areas, and enabling accurate polishing of the optical lens surface, thus guaranteeing the surface polishing quality of the lens.

[0028] The hydraulic telescopic rod 7 is located at the bottom of the movable block 6. Please refer to [link / reference]. Figure 5 The output end of the hydraulic telescopic rod 7 is equipped with a drive motor 8, and the output end of the drive motor 8 is equipped with a grinding disc 9.

[0029] Starting the first motor 4 can drive the first lead screw 5 to rotate, which in turn can drive the moving block 6 to move, which in turn can drive the hydraulic telescopic rod 7 to move, which in turn can drive the grinding disc 9 to move left and right. Starting the hydraulic telescopic rod 7 can drive the grinding disc 9 to move downward to contact the optical lens. Starting the drive motor 8 can drive the grinding disc 9 to rotate to grind the optical lens.

[0030] Please see Figure 4The second motor 10 is located in the rear part of the inner cavity of the grinding chamber 2. The rotor of the second motor 10 is coaxially mounted with a second lead screw 11. A moving rod 12 is screwed onto the surface of the second lead screw 11. A mounting bracket 13 is installed at the output end of the moving rod 12. Clamping plates 14 are provided on both sides of the inner cavity of the mounting bracket 13.

[0031] Starting the second motor 10 can drive the second lead screw 11 to rotate, which in turn can drive the moving rod 12 to move, which in turn can drive the clamping plate 14 to move back and forth, thus moving the optical lens clamped in the clamping plate 14.

[0032] A third motor 15 is installed on both inner walls of the mounting bracket 13. The rotor of the third motor 15 is coaxially mounted with a third lead screw 16. A positioning rod 17 is screwed onto the surface of the third lead screw 16. The inner end of the positioning rod 17 is connected to the surface of the clamping plate 14. Starting the third motor 15 can drive the third lead screw 16 to rotate, thereby driving the positioning rod 17 to move and causing the clamping plates 14 to move closer to each other.

[0033] The upper surface of the clamping plate 14 is equipped with mounting edges 18, and the inner wall of the mounting edges 18 is equipped with receiving plates 19. The clamping plate 14 will drive the mounting edges 18 to squeeze and position the optical lens. The receiving plates 19 are used to prevent the optical lens from falling off the bottom of the clamping plate 14.

[0034] The positioning rod 17 has sliders 20 installed on both the front and back sides. The mounting bracket 13 has slide rails 21 installed at the corresponding positions of the sliders 20. The sliders 20 are embedded in the slide rails 21, so that the positioning rod 17 can move linearly.

The limiting block 24 is inserted into the inside of the limiting groove 25, so that the mounting frame 13 can move linearly.

[0037] In operation, the following steps are taken: First, starting the third motor 15 drives the third lead screw 16 to rotate, which in turn moves the positioning rod 17, causing the clamping plates 14 to move closer together. The clamping plates 14 then move the mounting edge 18 to press and position the optical lens. The receiving plate 19 prevents the optical lens from falling off the bottom of the clamping plates 14. Next, starting the first motor 4 drives the first lead screw 5 to rotate, which in turn moves the moving block 6, which in turn moves the hydraulic telescopic rod 7, causing the grinding disc 9 to move left and right. Starting the hydraulic telescopic rod 7 causes the grinding disc 9 to move downwards to contact the optical lens. Starting the drive motor 8 causes the grinding disc 9 to rotate and grind the optical lens. Finally, starting the second motor 10 drives the second lead screw 11 to rotate, which in turn moves the moving rod 12, which in turn moves the clamping plates 14, causing the optical lens clamped in the clamping plates 14 to move back and forth, so that the grinding disc 9 can contact all parts of the optical lens.
