Description

Technical Field

[0001] This invention relates to the field of optical lens manufacturing technology, specifically to a multifunctional and efficient polishing machine for glass lenses. Background Technology

[0002] In optical systems, the size of a lens needs to be precisely matched with other optical components and mechanical structures. Edge grinding can precisely control the diameter, thickness, and other dimensions of the lens to meet the design tolerance range, ensuring that the lens can be accurately installed in the optical instrument and maintain the correct relative position with other components, thereby ensuring the stable performance of the entire optical system. The edge grinding process can remove defects, uneven parts, and stress concentration areas caused by previous processing such as cutting from the lens edge. These defects may cause problems such as light scattering and uneven refraction, affecting the imaging quality and optical performance of the lens. Through an edge grinding machine, the lens edge can be made smoother, reducing irregular refraction and scattering of light at the edge, and improving the lens's transmittance and image clarity.

[0003] Currently, in the polishing process of optical lenses, optical centering must first be achieved using a dedicated centering device before edge polishing can proceed. Operators have to frequently switch between the polishing machine and the centering device, which makes the operation process extremely cumbersome and prone to errors due to human factors. The end result is a significant reduction in production efficiency and a significant increase in production costs.

[0027] See attached document Figure 1-3 A multi-functional, high-efficiency glass lens polishing machine includes a frame 1. The frame 1 houses a polishing mechanism 2, a lens clamping mechanism 3, an adjustment mechanism 4, a center point positioning mechanism 5, and a Y-axis moving mechanism 6. The polishing mechanism 2 is responsible for polishing optical glass lenses to different degrees, sequentially from coarse grinding to fine grinding and then polishing, to achieve the required edge precision. The lens clamping mechanism 3 stably fixes the optical glass lens, ensuring no displacement during polishing. The adjustment mechanism is located at the upper end of the lens clamping mechanism 3, precisely adjusting the position and angle of the optical glass lens according to the sequence of center positioning, clamping, and polishing. The center point positioning mechanism 5 is located on one side of the lens clamping mechanism 3. The lower end of the polishing mechanism 2 is connected to the Y-axis moving mechanism 6. X-axis moving mechanisms 7 are provided on both sides of the lens clamping mechanism 3, driving the lens through the X-axis moving mechanisms 7. The clamping mechanism 3 moves back and forth, working in conjunction with the grinding mechanism 2 to perform rough grinding, fine grinding, and polishing. The adjustment mechanism 4 includes an X-axis linear module 401, a Z-axis linear module 402, a rotary cylinder 403, and a lens positioning frame 404. The X-axis linear module 401, Z-axis linear module 402, and rotary cylinder 403 drive the lens positioning frame 404 to perform position and angle adjustment actions. The center point positioning mechanism 5 includes a vision positioning camera module 501 and a patch positioning cylinder 502. The vision positioning camera module 501 captures images of the lens and uses image recognition technology to accurately determine the center position on the optical glass lens, providing an accurate positioning reference for the processing of the optical glass lens. The patch is pre-installed on the patch mounting block 503 of the patch positioning cylinder 502. After the positioning reference is determined, the patch is placed on the corresponding positioning center point of the optical glass lens.

[0028] The lens positioning frame 404 is connected to the rotary cylinder 403. The rotation of the rotary cylinder 403 can precisely drive the lens positioning frame 404 to adjust its angle, achieving a 90-degree flip to facilitate the reception of the lens clamping mechanism 3. The lens positioning frame 404 has a placement surface 4041, and a receiving groove 4042 is provided on one side of the placement surface 4041. Multiple positioning pins 4043 are fixed on the placement surface 4041. The optical glass lens is placed stably on the placement surface 4041, with one side inserted into the receiving groove 4042. Initial positioning is achieved by the positioning pins 4043. A light-transmitting hole 4044 is opened in the middle of the multiple positioning pins 4043. The multiple positioning pins 4043 cooperate with the light-transmitting hole 4044 to accurately fix the optical glass lens on the placement surface 4041. The light-transmitting hole 4044 allows the visual positioning camera module 501 to take pictures of the optical glass lens from below through the lens positioning frame 404, obtain a clear image of the lens, and thus more accurately determine key information such as the center position of the optical glass lens.

[0029] The visual positioning camera module 501 is located below the lens positioning frame 404, enabling it to clearly capture images of the optical glass lens placed on the lens positioning frame 404. Through the principle of optical imaging, the visual positioning camera module 501 transmits the image information of the optical glass lens to the control system. The control system uses image processing algorithms to analyze the image, thereby determining key parameters such as the position and angle of the optical glass lens. The patch positioning cylinder 502 is fixedly connected to the frame 1 through an L-shaped bracket. The L-shaped bracket ensures the stability of the patch positioning cylinder 502 installation. The patch positioning cylinder 502 can rotate and lift under the command of the control system. When a center point marker patch is pasted on the optical glass lens, the patch positioning cylinder 502 can accurately deliver the patch to the designated position.

[0030] The patch positioning cylinder 502 is located on one side of the vision positioning camera module 501. The piston end of the patch positioning cylinder 502 is connected to the patch mounting block 503. When the patch positioning cylinder 502 extends the piston, it drives the patch mounting block 503 to move towards the lens positioning frame 404. The patch mounting block 503 is pre-installed with patches that need to be pasted on the optical glass lens. After moving to the designated position, the patch mounting block 503 accurately pastes the patch onto the optical glass lens.

[0031] The grinding mechanism 2 is located at the rear end of the lens clamping mechanism 3. The grinding mechanism 2 includes a coarse grinding wheel 201, a fine grinding wheel 202, and a polishing wheel 203. The coarse grinding wheel 201 is used for preliminary grinding of the optical glass lens edge, removing most of the excess material and quickly processing the optical glass lens to the required specifications. The fine grinding wheel 202 further refines the optical glass lens, improving the edge smoothness and precision. The polishing wheel 203 performs the final polishing process on the optical glass lens, ensuring its smoothness and precision. The surface achieves a high gloss, meeting the edge grinding requirements of optical lenses. The coarse grinding wheel 201, fine grinding wheel 202, and polishing wheel 203 are connected on both sides by a linkage shaft. One end of the linkage shaft is equipped with a first rotary motor 204. The linkage shaft and the drive end of the first rotary motor 204 are connected by a synchronous belt. The speed of the first rotary motor 204 is controlled by the control system, and different grinding wheels are switched to work. The coarse grinding wheel 201 is used for coarse grinding. After reaching a certain degree, it is switched to the fine grinding wheel 202 for fine grinding. Finally, the polishing wheel 203 is used for polishing.

[0032] The lens clamping mechanism 3 includes two mirror-arranged clamping rods 301. One end of each clamping rod 301 is provided with a positioning shaft 302 and a second rotary motor 303. A positioning seat 304 is sleeved on the positioning shaft 302. One end of the X-axis moving mechanism 7 is connected to the positioning seat 304. The two positioning seats 304 are located on both sides of the frame 1. When clamping the lens, the two X-axis moving mechanisms 7 push the clamping rods 301 inward to control the extension and retraction force of the clamping rods 301 and clamp both sides of the optical glass lens. The positioning shaft 302 on one side is driven to rotate by the second rotary motor 303 to control the rotation amplitude of the clamping rod 301. This works in conjunction with the grinding mechanism 2 to grind the edge of the optical glass lens.

[0033] In this embodiment, the operation process is as follows:

[0034] First, the lens positioning frame 404 on the adjustment mechanism 4 is moved to the position of the operation window 101 and is in a horizontal state. The optical glass lens is placed on the placement surface 4041 of the lens positioning frame 404 by manual means, and one side is inserted into the receiving groove 4042. It is pre-positioned by multiple positioning pins 4043. Then, the positioning patch used for centering is installed on the patch mounting block 503. After the positioning center point is confirmed by the cooperation of the vision positioning camera module 501 and the X-axis linear module 401, the patch positioning cylinder 502 is started, which drives the patch mounting block 503 to press the patch onto the lens positioning frame 404.

[0035] Then, the X-axis linear module 401 is restarted, driving the lens positioning frame 404 to move the optical glass lens with the positioning patch attached towards the lens clamping mechanism 3, stopping between the two clamping rods 301. The rotary cylinder 403 is started to rotate 90 degrees counterclockwise, raising the optical glass lens. The Z-axis linear module 402 is started to descend, and at the same time, the two clamping rods 301 extend inward to clamp the two sides of the optical glass lens, thereby realizing the operation of transferring the optical glass lens from the adjustment mechanism 4.

[0036] Finally, the second rotary motor 303 on the lens clamping mechanism 3 is started to rotate the positioning turntable 302, which drives the optical glass lens to rotate. The grinding mechanism 2 is started, and the coarse grinding wheel 201, fine grinding wheel 202 and polishing wheel 203 rotate at high speed. During the grinding process, the Y-axis moving mechanism 6 is started to push the grinding mechanism 2 towards the lens clamping mechanism 3, so that the grinding wheel contacts the edge of the optical glass lens. The X-axis moving mechanisms 7 on both sides of the lens clamping mechanism 3 are started, so that the lens clamping mechanism 3 drives the optical glass lens to move back and forth along both sides of the equipment. The coarse grinding wheel 201, fine grinding wheel 202 and polishing wheel 203 are used to perform coarse grinding, fine grinding and polishing operations on the optical glass lens in sequence. After the grinding is completed, the optical glass lens is taken out from the front of the equipment.

[0037] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
