Description

Technical Field

[0001] The utility model relates to the technical equipment field of lens processing, and specifically to an outer contour polishing machine for elliptical lenses. Background Technique

[0002] With the progress of optical technology, due to their unique optical properties and aesthetics, elliptical lenses are widely used in fields such as glasses, camera lenses, and optical instruments. During the lens manufacturing process, outer contour polishing is a crucial process that directly affects the optical performance and appearance quality of the lenses. Taking glasses as an example, in glasses manufacturing, according to the usage requirements of the lenses, they can be divided into two types: semi-frame glasses and full-frame glasses. Semi-frame glasses mean that the elliptical lens is only surrounded by half of the frame, and the other half is exposed. Semi-frame polishing refers to polishing the edge of the half of the elliptical lens that is not surrounded by the frame to make its edge smooth, beautiful, and meet the design requirements; lenses for semi-frames only need to polish half of the elliptical edge, mainly used for fashion glasses and some special optical devices, while lenses for full-frames need to polish the entire elliptical edge and are widely used in ordinary glasses and high-end optical devices.

[0003] For example, Chinese Patent CN221818230U discloses a fine grinding and polishing device for high-precision optical lens processing, including a base. At the middle position on the top of the base, there is a U-shaped frame. A bracket is fixed on the top of the base, and a telescopic cylinder is installed at the bottom of the bracket. The output end of the telescopic cylinder is installed with a mounting plate, and a grinding motor is installed at the bottom end of the mounting plate. The output end of the grinding motor is installed with a grinding disc, which will not cause environmental pollution and is more environmentally friendly to use. However, in the process of specific application of the above polishing device, there are the following deficiencies: First, the device mainly considers the polishing of circular lenses, and the design of the grinding disc cannot directly meet the polishing requirements of elliptical lenses. It needs to be adjusted multiple times to polish the contour of the elliptical lens and cannot complete semi-frame polishing at one time because the contour shape of the elliptical lens is different from that of the circular lens, resulting in a cumbersome and time-consuming polishing process; Second, the device cannot ensure that the elliptical lens maintains a stable position during the polishing process, and may cause uneven polishing or damage due to the movement or falling off of the lens during the polishing process, with poor practicability.

[0029] In one embodiment, for the above-mentioned first moving component 3 and second moving component 4, the first moving component 3 includes two groups of first guide rails 301 symmetrically arranged in the middle of the top end of the workbench 1. One end of the top end of the workbench 1 is provided with a first limit seat 302 (in addition, in specific applications, the first limit seat 302 is provided with a limit hole matching the first adjusting rod 304). The other end of the top end of the workbench 1 is provided with a first air cylinder 303. The output end of the first air cylinder 303 is connected with a first adjusting rod 304 (in addition, in specific applications, the output end of the first air cylinder 303 is fixedly connected with the first adjusting rod 304). The first adjusting rod 304 penetrates through a limit vertical block 305 fixedly connected with the workbench 1. The second moving component 4 includes a first support plate 401 arranged at the top end of the first moving component 3. Chutes 402 matching the first guide rails 301 are provided on both sides of the bottom end of the first support plate 401 (in addition, in specific applications, the first support plate 401 is fixedly connected with a first support slider 403). A first support slider 403 matching the first adjusting rod 304 is arranged through the middle of the bottom end of the first support plate 401 (in addition, in specific applications, the first adjusting rod 304 penetrates through the middle of the first support slider 403 and the two are fixedly connected). Second guide rails 404 are symmetrically arranged on both sides of the top end of the first support plate 401. One end of the top end of the first support plate 401 is provided with a second limit seat 405 (in addition, in specific applications, the second limit seat 405 is fixedly connected with the first support plate 401). The other end of the top end of the first support slider 403 is provided with a second air cylinder 406 (in addition, in specific applications, the second air cylinder 406 is fixedly connected with the first support plate 401). The output end of the second air cylinder 406 is connected with a second adjusting rod 407. The second adjusting rod 407 penetrates through a limit vertical plate 408 fixedly connected with the first support plate 401. A second support slider 409 is sleeved on the middle of the second adjusting rod 407 (in addition, in specific applications, the second adjusting rod 407 is fixedly connected with the second support slider 409, and the second support slider 409 is fixedly connected with a second support plate 410). A second support plate 410 matching the second guide rails 404 is arranged at the top end of the second support slider 409 (in addition, in specific applications, limit chutes matching the second guide rails 404 are provided on both sides of the bottom end of the second support plate 410). Thus, through the cooperation of the two moving components, the lens clamping component 5 can move to any position in the plane to achieve precise polishing of the outer contours of elliptical lenses with different sizes and shapes.

[0030] The working principle of the first moving component 3 is as follows: The first guide rail 301 provides a linear movement path in the longitudinal direction, enabling the first moving component 3 to perform linear motion along the length direction of the workbench 1. The two symmetrically arranged first guide rails 301 ensure the parallelism and stability of the movement. The first limit seat 302 limits the movement range of the first moving component 3 by providing limit holes that cooperate with the first adjusting rod 304, preventing it from exceeding the predetermined movement area. The first cylinder 303, through the fixed connection of its output end to the first adjusting rod 304, provides longitudinal power and reciprocating adjustment ability, enabling the limit vertical block 305 to drive the second moving component 4 to move longitudinally under the action of the cylinder and ensuring the stability of the movement.

[0031] The working principle of the second moving component 4 is as follows: The second guide rail 404 provides a linear movement path in the transverse direction. By controlling the second cylinder 406 to drive the second adjusting rod 407 to move transversely, the second adjusting rod 407 then drives the second support plate 410 to move transversely through the second support slider 409. The second support plate 410 drives the lens clamping component 5 at the top to move. Finally, through the cooperation of the first moving component 3 and the second moving component 4, the lens clamping component 5 can move to any position within the plane, enabling the polishing machine to adapt to the polishing requirements of the outer contours of elliptical lenses of different sizes and shapes and ensuring the stability of the movement.

[0032] In one embodiment, for the above-mentioned lens clamping assembly 5, the lens clamping assembly 5 includes an elastic pressing block 501 disposed at the middle of the top end of the second moving assembly 4 (in addition, in specific applications, the elastic pressing block 501 is fixedly connected to the second support plate 410, and it is made of rubber, and the shape of the upper surface is designed as a curved surface matching the surface curvature of the elliptical lens 10 to ensure that it can closely fit the lens edge during the clamping process), a first L-shaped rib plate 502 is disposed on one side of the top end of the second moving assembly 4 (in addition, in specific applications, the first L-shaped rib plate 502 is fixedly connected to the second support plate 410 and the second L-shaped rib plate 503), a second L-shaped rib plate 503 is disposed at the top end of the first L-shaped rib plate 502, a clamping block 504 is disposed on one side of the second L-shaped rib plate 503 (in addition, in specific applications, the clamping block 504 is fixedly connected to the top of the second L-shaped rib plate 503 and the electric telescopic rod 505), an electric telescopic rod 505 is disposed through the bottom end of the clamping block 504, a pressure rod 506 is fixedly connected to the bottom end of the electric telescopic rod 505 (in addition, in specific applications, the bottom end of the electric telescopic rod 505 is a telescopic output end), a convex block 507 is sleeved outside the pressure rod 506 (in addition, in specific applications, a limiting hole matching the pressure rod 506 is opened at the top end of the convex block 507), a U-shaped connecting member 508 is sleeved at the bottom of the pressure rod 507 (in addition, in specific applications, the convex block 507 is fixedly connected to the U-shaped connecting member 508, and both ends of the U-shaped connecting member 508 are movably connected to the L-shaped pressure block 509 through a pin shaft), L-shaped pressure blocks 509 are symmetrically disposed at both ends of the U-shaped connecting member 508 (in addition, in specific applications, the L-shaped pressure block 509 is movably connected to the connecting arm 510 through a pin shaft), connecting arms 510 fixedly connected to the bottom end of the convex block 506 are disposed on both sides of the middle of the L-shaped pressure block 509, and one side of the convex block 507 is fixedly connected to the first L-shaped rib plate 502 through a fixed shaft, thereby realizing gentle clamping and stable support of the elliptical lens 10, and ensuring the accuracy and safety of the polishing process.

[0033] It should be noted that in specific applications, a hemispherical friction block is sleeved at the bottom end of the pressure rod 506, and a sector-shaped friction block is disposed at the bottom end of the L-shaped pressure block 509. Both the hemispherical friction block and the sector-shaped friction block are made of rubber that does not damage the elliptical lens 10. This material has good elasticity and wear resistance, and can reduce the wear of the elliptical lens 10 while providing the necessary pressure. This is the prior art and will not be elaborated here.

[0034] The working principle of the lens clamping assembly 5 is as follows: The elastic pressing block 501 is made of rubber and is fixedly connected to the second support plate 410, and is used to directly contact and fix the lens. The first L-shaped rib plate 502 is fixedly connected to the second support plate 410 and the second L-shaped rib plate 503 to provide structural support and positioning. The second L-shaped rib plate 503 is arranged at the top of the first L-shaped rib plate 502 to further enhance the structural stability. The clamping block 504 is fixedly connected to the top of the second L-shaped rib plate 503 and the electric telescopic rod 505, and is used to fix the electric telescopic rod 505. Thus, by controlling the telescopic movement of the output end of the electric telescopic rod 505, the pressure rod 506 is driven to lift and lower. The pressure rod 506 drives the L-shaped pressure block 509 to change the angle around the pin shaft through the U-shaped connecting piece 508. When the pressure rod 506 is pressed down, the L-shaped pressure blocks 509 at both ends are lifted up, and the sector friction blocks at the bottom can provide appropriate pressure at both ends of the elliptical lens 10. The hemispherical friction block at the bottom of the pressure rod 506 provides the pressure in the middle. Thus, the elliptical lens 10 is clamped in cooperation with the elastic pressing block 501 at the bottom to ensure that the elliptical lens 10 does not move or fall off during the polishing process.

[0035] In one embodiment, for the above-mentioned contour polishing assembly 9, the contour polishing assembly 9 includes two groups of welding frames 901 symmetrically arranged at the middle part of the bottom end of the mounting plate 8 (in addition, in specific applications, the welding frame 901 is fixedly connected to the mounting plate 8 and the U-shaped welding plate 902). The bottom end of the welding frame 901 is provided with a U-shaped welding plate 902. One side of the U-shaped welding plate 902 is fixedly connected to the mounting vertical plate 903. One side of the mounting vertical plate 903 is provided with a motor bracket 904 (in addition, in specific applications, the motor bracket 904 is fixedly connected to the mounting vertical plate 903 and the fixing plate 907). The top end of the motor bracket 904 is provided with a driving motor 905 (in addition, in specific applications, the driving motor 905 is set as a servo motor). The output end of the driving motor 905 passes through the motor bracket 904 and is connected to the first rotating wheel 906. The bottom end of the motor bracket 904 is provided with a fixing plate 907. The top end of one side of the fixing plate 907 is provided with a rotating seat 908 penetrating through (in addition, in specific applications, the fixing plate 907 is fixedly connected to the rotating seat 908). The top end of the rotating seat 908 is provided with a driving shaft 909 penetrating through (in addition, in specific applications, the driving shaft 909 is fixedly connected to the second rotating wheel 911 and the polishing cutter head 910). The bottom end of the driving shaft 909 is fixedly connected to the polishing cutter head 910. The outer side of the top end of the driving shaft 909 is sleeved with a second rotating wheel 911, and the second rotating wheel 911 is connected to the first rotating wheel 906 through a belt, so as to provide continuous polishing power. Through the cooperation of the servo motor and the transmission mechanism, the polishing of the outer contour of the elliptical lens 10 is realized.

[0036] The working principle of the contour polishing assembly 9 is as follows: The welding frame 901 is fixedly connected to the mounting plate 8 and the U-shaped welding plate 902, providing structural support and stability for the contour polishing assembly 9. The motor bracket 904 is fixedly connected to the mounting vertical plate 903 and the fixing plate 907, providing a mounting position for the driving motor 905. The output end of the driving motor 905 is connected to the first rotating wheel 906. Through belt transmission, power is transmitted to the second rotating wheel 911. The second rotating wheel 911 is fixedly connected to the driving shaft 909. The outer side of the top end of the driving shaft 909 is sleeved with the second rotating wheel 911, forming a closed-loop transmission system. The bottom end of the driving shaft 909 is fixedly connected with a polishing cutter head 910. The polishing cutter head 910 is a component directly participating in the polishing process, used to remove burrs on the outer contour of the lens and achieve the polishing effect.

[0037] To facilitate the understanding of the above technical solution of the present invention, the working principle or operation mode of the present invention in the actual process will be described in detail below.

[0038] In actual application, the operator first places the elliptical lens 10 on the elastic pressing block 501 of the lens clamping assembly 5, and ensures that the lens is firmly clamped through the lens clamping assembly 5 (the working principle of the lens clamping assembly 5 is as described above). Through the control panel, the operator sets the trajectory parameters for half-frame polishing, and controls the first cylinder 303 and the second cylinder 406 to start working, respectively driving the first adjusting rod 304 and the second adjusting rod 407, so that the lens clamping assembly 5 can move along the transverse X-axis and the longitudinal Y-axis directions on the workbench 1. Then, the driving motor 905 is started, and the polishing cutter head 910 is driven to rotate through the belt transmission system (the working principle of the contour polishing assembly 9 is as described above). The lens clamping assembly 5 moves along the preset trajectory under the control of the first moving assembly 3 and the second moving assembly 4 (the working principles of the first moving assembly 3 and the second moving assembly 4 are as described above). The polishing cutter head 910 polishes the outer contour of the elliptical lens 10. The structures of the elastic pressing block 501 and the L-shaped rib plates 502 and 503 ensure that the lens remains stable during the polishing process and will not affect the polishing effect due to movement or detachment. When the polishing reaches the preset parameters, the driving motor 905 stops working, the polishing cutter head 910 stops rotating, the first cylinder 303 and the second cylinder 406 stop working, and the lens clamping assembly 5 returns to the initial position. The operator takes out the polished elliptical lens 10 and checks the polishing effect. If not satisfied, the parameters are adjusted and polishing is carried out again. If satisfied, the half-frame polishing ends. Then, the direction of the elliptical lens 10 is changed, and the remaining half of the elliptical contour is continued to be polished for the remaining half-frame. By repeating the above operations, full-frame polishing is completed to ensure that the smoothness and shape of the edge of the elliptical lens 10 meet the requirements of the optical system.
