Description

Technical Field

[0001] The utility model relates to the technical field of lens processing equipment, in particular to a lens polishing device. Background Art

[0002] After the optical lens is finely ground with abrasive liquid, there is still a crack layer about 2-3mm thick on its surface. The method to eliminate this crack layer is usually polishing. Flannel cloth, polishing leather and asphalt are used, and a polishing wheel made of soft materials such as fluff, silk or rubber is used. When the polishing wheel rotates, it contacts the surface of the lens and removes the roughness and defects on the lens surface through friction.

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0027] like Figure 1-Figure 5 As shown, a lens polishing device comprises a polishing box 1 and a flip assembly 2, a polishing assembly 4 and a pressing assembly 3 located in the polishing box 1, wherein the polishing assembly 4 is located in the middle of the bottom of the polishing box 1, the pressing assembly 3 is located in the middle of the top of the polishing box 1, and the flip assembly 2 is located between the polishing assembly 4 and the pressing assembly 3;

[0028] The flip assembly 2 includes a plurality of flip shafts 201 and a driving motor 202. The plurality of flip shafts 201 are rotatably connected to the side walls of the polishing box 1 respectively. Two adjacent flip shafts 201 are connected by gears and chains. The flip shafts 201 are rotated by the driving motor 202.

[0029] The flip shaft 201 is provided with a placement component, which includes a placement frame 203 and a clamping component. The clamping component is slidably connected to the placement frame 203, and the lens 5 is fixed by the clamping component.

[0030] The pressing assembly 3 cooperates with the clamping assembly, and the clamping assembly is fixed by the pressing assembly 3 .

[0031] Through the above technical scheme, the lens 5 is placed in the placement rack 203 and the side wall of the lens 5 is clamped by the clamping assembly. At this time, the lens 5 is in a suspended state, and then the clamping assembly is fixed by the pressing assembly 3 to prevent the subsequent lens 5 from shaking during the polishing process, and then one side of the lens 5 is polished by the polishing assembly 4; after the polishing of one side of the lens 5 is completed, the pressing assembly 3 is reset, and then the placement rack 203, the clamping assembly and the lens 5 are turned over as a whole by the flipping assembly 2. At this time, the unpolished side of the lens 5 faces the polishing assembly 4, and then it is pressed by the pressing assembly 3, and the other side of the lens 5 is polished by the polishing assembly 4.

[0032] The above structure can be used to complete double-sided polishing of the lens 5, reduce the intensity of manual turning over, and improve the efficiency of turning over and polishing; at the same time, multiple lenses 5 can be placed to complete double-sided polishing of multiple lenses 5, further improving the polishing efficiency; at the same time, the flipping component 2 only flips each placement rack 203 and lens 5, reducing the space occupied during turning over and improving space utilization.

[0033] Furthermore, a plurality of the placement racks 203 are arranged in a circle, the placement rack 203 is a U-shaped structure, the middle parts of both sides of the placement rack 203 are respectively fixedly connected to the flip shaft 201, the clamping assembly includes two symmetrically arranged groups of springs 205, wedge blocks 204 and sliders 207, the sliders 207 are I-shaped structures, one end of the spring 205 is fixed to the middle part of the slider 207, the other end of the spring 205 is connected to the wedge block 204, installation cavities 208 are symmetrically provided on both sides of the placement rack 203, the inner dimensions of the installation cavities 208 are adapted to the outer dimensions of the slider 207, the slider 207 is located in the installation cavity 208, the wedge block 204 is located in the U-shaped groove of the placement rack 203, the placement rack 203 is provided with a slot corresponding to the position of the spring 205, and the length of the slot is the same as the length of the installation cavity 208.

[0034] According to the above technical solution, the placement rack 203 is a U-shaped structure, the middle of the placement rack 203 is hollow, and the two sides are fixedly connected by the flip shaft 201, and the rotation of the flip shaft 201 drives the placement rack 203 to rotate. When the lens 5 is not placed, the wedge block 204 extends into the middle of the placement rack 203 under the elastic force of the spring 205. When the lens 5 is placed in the placement rack 203, two symmetrical wedge blocks 204 clamp the two sides of the lens 5 respectively, and the wedge blocks 204 compress the spring 205. At this time, the wedge blocks 204 are fixed by the elastic force of the spring 205.

[0035] Furthermore, through holes 206 are provided at the upper and lower ends of the installation cavity 208 , and the diameter of the through holes 206 is smaller than the inner diameter of the installation cavity 208 .

[0036] Furthermore, the clamping assembly 3 includes a telescopic cylinder 301, a connecting plate 302 and a pressure rod 303. The cylinder seat of the telescopic cylinder 301 is fixed on the top of the polishing box 1. The piston rod of the telescopic cylinder 301 extends into the polishing box 1 and is connected to the connecting plate 302. The size of the connecting plate 302 is adapted to the circular size formed by the multiple placement racks 203. The pressure rod 303 is fixed below the connecting plate 302. The position of the pressure rod 303 corresponds to the position of the through hole 206. The diameter of the pressure rod 303 is adapted to the inner diameter of the through hole 206.

[0037] Through the above technical solution, when the lens 5 is clamped and fixed by the clamping assembly, the slider 207 is at the bottom of the installation cavity 208 under the action of its own weight. When the slider 207 slides in the installation cavity 208, the spring 205 also drives the wedge block 204 and the lens 5 to slide through the slot. Then, the pressing rod 303 is driven by the telescopic cylinder 301 to be pressed into the through hole 206, and the slider 207 is pressed against the inner wall of the bottom end of the installation cavity 208 by the pressing rod 303, and the lens 5 extends out from the bottom of the placement rack 203. At this time, the polishing assembly 4 rises to polish the lens 5 close to the side of the polishing assembly 4. Since the lower end surface of the lens 5 is lower than the lower end surface of the placement rack 203, the polishing assembly 4 will only polish the lens 5 and will not affect the placement rack 203; after the polishing of one side of the lens 5 is completed, the pressing assembly 3 and the polishing assembly 4 are reset, and then the turning shaft 201 is driven to rotate by the driving motor 202 and the chain belt, and the adjacent turning shaft 201 is rotated by the chain belt. At this time, the turning over of the lens 5 is completed by the turning assembly 2, and then the slider 207 falls to the bottom of the installation cavity 208 by its own weight, so that the lens 5 protrudes from the placement rack 203, which is convenient for the polishing of the polishing assembly 4.

[0038] Furthermore, the polishing assembly 4 includes a hydraulic cylinder 401, a support plate 403, a rotating motor 402 and a polishing disc 404, the cylinder seat of the hydraulic cylinder 401 is fixed to the bottom of the polishing box 1, the piston rod of the hydraulic cylinder 401 is connected to the bottom of the support plate 403, the motor seat of the rotating motor 402 is fixed to the bottom of the support plate 403, the rotating shaft of the rotating motor 402 passes through the support plate 403 and is connected to the polishing disc 404, and the size of the polishing disc 404 is adapted to the size of the circle formed around the multiple placement racks 203.

[0039] Through the above technical solution, the polishing disc 404 has a circular size that matches the circular size of the multiple placement racks 203, so that the lenses 5 in all the placement racks 203 can be polished by one polishing disc 404. Before polishing, the polishing disc 404, the rotating motor 402 and the support plate 403 are retracted by the hydraulic cylinder 401; during polishing, the hydraulic cylinder 401 is raised so that the polishing disc 404 is located below the lens 5, and then the rotating motor 402 is started to drive the polishing disc 404 to rotate to polish the lens 5. After one side of the lens 5 is polished, the polishing assembly 4 is reset by the hydraulic cylinder 401, leaving space for the placement rack 203 to flip over without affecting the flipping of the lens 5. After the lens 5 is flipped over, the polishing assembly 4 is raised for polishing.

[0040] Furthermore, the thickness of the wedge block 204 is smaller than the thickness of the lens 5 , and one side of the lens 5 extends out of the placement frame 203 through the pressure rod 303 .

[0041] Through the above technical solution, the thickness of the wedge block 204 is smaller than the thickness of the lens 5. At the same time, the thickness of the slider 207 and the diameter of the spring 205 are also smaller than the lens 5. When the slider 207 falls on the bottom of the mounting cavity 208, it ensures that the lower end surface of the lens 5 is lower than the lower end surface of the placement frame 203, so that the polishing assembly 4 can contact the lens 5.

[0042] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
