Description

[0001] The present invention relates to the technical field of lens polishing, and more specifically, to a polishing device for producing optical lenses. Background Art

[0002] Optical lenses are elements used to control the direction of light propagation, focus light or scatter light. They are widely used in various optical systems, such as glasses, microscopes, telescopes, camera lenses, and laser equipment. Optical lens polishing is a crucial step in the lens manufacturing process. It determines the smoothness and flatness of the optical lens surface and directly affects the accuracy of the optical lens.

[0003] The existing optical lens polishing generally involves adhering and fixing one side of the lens with glue, and then polishing the other side of the lens with a polishing disk. This polishing method cannot polish both sides of the lens at the same time, which results in the need to replace the fixed surface for a second polishing after polishing one side of the optical lens, and the side with glue needs to be cleaned after the optical lens is polished. During the cleaning process, if there are slight depressions on the surface of the optical lens, glue residue will remain in the depressions of the optical lens, resulting in spots on the lens during use, affecting the accuracy of the lens when used. Summary of the invention

The limit plate is provided with limit holes distributed in an arc shape. The limit pin is slidably connected to the rotating disk and the adjacent limit hole, and an elastic member is fixedly connected between the limit pin and the rotating disk.

[0008] Furthermore, it also includes: An extrusion pin is fixedly connected to a side of the limiting plate away from the rotating plate; An elastic telescopic rod is fixedly connected to a position of the workbench close to the extrusion pin, and a pressure sensor is fixedly connected to the telescopic portion of the elastic telescopic rod; An extrusion block is slidably connected to the fixed portion of the elastic telescopic rod, the extrusion pin is used to extrude the extrusion block, and the extrusion block is used to extrude the pressure sensor; An electrically controlled telescopic rod, fixedly connected to the workbench; The regulating valve is installed on the conduit between the liquid storage tank and the nozzle, and the telescopic part of the electric control telescopic rod and the regulating valve are transmitted through a third transmission member.

[0009] Furthermore, the distance between the extrusion block and the limiting plate is gradually shortened along the rotation direction of the rotating plate.

[0010] Furthermore, it also includes: There are two adjustment plates, which are respectively fixed to the adjacent liquid storage tanks. The adjustment plates are provided with arc-shaped holes. The nozzles are sealed and slidably connected to the adjustment plates. The nozzles are connected to the adjacent holes. The aperture of a single hole gradually increases from close to the rotating disk to far away.

[0011] Furthermore, the diameters of all the holes on the same adjusting plate increase sequentially from the position close to the center of the rotating disk to the position far away from the rotating disk.

[0012] Furthermore, the outer diameter of the nozzle is A, the inner diameter of the nozzle is B, the aperture of the hole is C, and A-B>C.

[0013] Furthermore, the inner diameter of the nozzle on the lower side is larger than the inner diameter of the nozzle on the upper side, and the apertures of the holes on the lower side are larger than the apertures of the corresponding holes on the upper side.

[0014] Furthermore, it also includes: There are two sliding plates, which are slidably connected to the adjacent liquid storage tanks respectively, and the sliding plates and the rotating shaft of the output shaft on the third motor are transmitted through a fourth transmission member.

By setting holes of different apertures, the nozzles are connected with holes of different apertures in sequence, so that the amount of polishing liquid sprayed out is less as the nozzles are directed toward the center of the lens, so as to adapt to the different polishing areas of the inner and outer circles of the lens, thereby improving the uniformity of lens polishing and further improving the precision of the lens after polishing; 4. By moving the sliding plate, the polishing liquid in the storage tank keeps flowing during use to prevent the abrasive particles in the polishing liquid from being deposited, thereby reducing the amount of abrasive particles in the polishing liquid sprayed from the nozzle, thereby affecting the use effect of the polishing liquid and affecting the normal polishing of the lens.

[0020] like Figure 1-Figure 6 As shown, the guide assembly includes: a limit plate 2, which is rotatably connected to the workbench 1 and is located between the two polishing plates 102. The limit plate 2 is fixedly connected with limit frames 201 distributed circumferentially and the number of which is the same as the number of clamping rods 301. The clamping rods 301 slide in adjacent limit frames 201. The limit frames 201 are arc-shaped. Figure 1 The top view is the rotation reference. When the limit plate 2 drives all the limit frames 201 to rotate counterclockwise, the clamping rod 301 moves along the adjacent limit frames 201 to the center of the limit plate 2. The workbench 1 is equipped with a first motor 202 electrically connected to the control terminal. The limit plate 2 and the output shaft of the first motor 202 are transmitted through a first transmission member, wherein the first transmission member is composed of a first gear and a first gear ring, the first gear is fixedly connected to the output shaft of the first motor 202, the first gear ring is fixedly connected to the limit plate 2, and the limit plate 2 is provided with arc-shaped limit holes 401; the limit pin 4 is slidably connected to the rotating plate 3 and the adjacent limit hole 401, and an elastic member is fixedly connected between the limit pin 4 and the rotating plate 3, wherein the elastic member is a tension spring, and when the limit pin 4 is located in the adjacent limit hole 401, the elastic member of the limit pin 4 is in an initial unstretched state.

[0021] like Figure 3 , Figure 7 and Figure 8 As shown, the liquid injection component 5 includes: a liquid storage tank 501, which is fixedly connected to the workbench 1 and connected to an external liquid supply device, and the external liquid supply device is electrically connected to the control terminal; a third motor 502, which is fixedly connected to the workbench 1, and the third motor 502 is electrically connected to the control terminal, and the output shaft of the third motor 502 is fixedly connected to a nozzle 503 through a rotating shaft, and the liquid storage tank 501 and the nozzle 503 are connected through a conduit, and the liquid storage tank 501 and the nozzle 503 and the conduit therebetween are all made of stainless steel to reduce the corrosion effect of the alkaline substances in the polishing liquid on them.

[0022] The specific working principle is as follows: When it is necessary to use the device to polish an optical lens (hereinafter referred to as the lens), the operator places the lens between all the clamping rods 301, and then the operator pulls the limit pin 4 upwards to stretch the elastic part of the limit pin 4. The operator turns on the first motor 202 through the control terminal, and the output shaft of the first motor 202 drives the limit plate 2 to rotate counterclockwise through the first transmission member, and the limit plate 2 drives all the limit frames 201 thereon to rotate, and the limit frames 201 squeeze the clamping rods 301, so that the circumferentially distributed clamping rods 301 all move toward the center of the limit plate 2. When all the clamping rods 301 move to clamp the lens, the operator turns off the first motor 202 through the control terminal, and then releases the limit pin 4, so that the limit pin 4 is inserted into the corresponding limit hole 401 at this time, changing the existing form of fixing the lens with glue.

[0023] When the lens is fixed, the operator starts the second motor 302 through the control terminal, and the output shaft of the second motor 302 drives the rotating disk 3 to rotate through the second transmission member, and the rotating disk 3 drives the limit disk 2 to rotate through the limit pin 4. At the same time, the operator starts the first motor 202 again through the control terminal, and the output shaft of the first motor 202 drives the limit disk 2 to rotate through the first transmission member, and the limit disk 2 and the rotating disk 3 jointly drive all the clamping rods 301 to rotate, so that the lens rotates. At this time, the operator starts the upper and lower driving arms 101 at the same time through the control terminal, and the two driving arms 101 respectively drive the adjacent polishing disks 102 to shake horizontally, and polish the upper and lower surfaces of the lens respectively. By polishing the upper and lower surfaces of the lens at the same time, the efficiency of lens polishing is improved, and it is prevented that after one side of the lens is polished, there are spots on the lens surface due to glue residue on the other side, thereby affecting the accuracy of the lens when used.

[0024] During the lens polishing process, the operator turns on the external liquid supply device and the third motor 502 through the control terminal. The external liquid supply device transports the polishing liquid to the liquid storage tank 501. The polishing liquid in the liquid storage tank 501 enters the nozzle 503 along its conduit. The nozzle 503 sprays the polishing liquid onto the surface of the lens. At the same time, the output shaft of the third motor 502 drives the nozzle 503 to rotate through the rotating shaft. As the lens rotates, the polishing liquid is sprayed from the center of the lens to the edge of the lens, and so on and so forth, so that the polishing liquid is sprayed to various parts of the lens to assist the polishing disk 102 in polishing the lens surface.

[0025] When the lens is polished, the operator turns off the driving arm 101, the first motor 202, the second motor 302, the external liquid supply device and the third motor 502 through the control terminal. Then the operator pulls the limit pin 4 out of the corresponding limit hole 401, and then controls the output shaft of the first motor 202 to rotate in the opposite direction through the control terminal. The output shaft of the first motor 202 drives the limit plate 2 to rotate clockwise through the first transmission member, so that all the limit frames 201 squeeze the adjacent clamping rods 301 to move respectively, and the clamping rods 301 move and lose the clamping of the lens. The operator removes the lens for collection and loosens the limit pin 4. The elastic part of the limit pin 4 rebounds and resets, so that the limit pin 4 is inserted into the corresponding limit hole 401. Finally, the device is cleaned for the next use.

[0026] like Figure 4-Figure 6 and Figure 8As shown, it also includes: an extrusion pin 601, which is fixedly connected to the lower side of the limit plate 2; an elastic telescopic rod 602, which is fixedly connected to the position of the workbench 1 near the extrusion pin 601, and the telescopic part of the elastic telescopic rod 602 is fixedly connected to a pressure sensor 603, and the pressure sensor 603 is electrically connected to the control terminal. The greater the pressure on the pressure sensor 603, the smaller the rotation amplitude of the output shaft of the third motor 502; an extrusion block 604, which is slidably connected to the fixed part of the elastic telescopic rod 602, the extrusion pin 601 is used to squeeze the extrusion block 604, and the extrusion block 604 is used to squeeze the pressure sensor 603, so as to Figure 1 Taking the top view of as the reference of the rotation direction, the distance between the extrusion block 604 and the limit plate 2 is gradually shortened in the counterclockwise direction; the electric telescopic rod 605 is fixedly connected to the workbench 1, and the electric telescopic rod 605 is electrically connected to the control terminal; the regulating valve 606 is installed on the conduit between the liquid storage tank 501 and the nozzle 503, and the regulating valve 606 is provided with a valve. The telescopic part of the electric telescopic rod 605 and the valve of the regulating valve 606 are transmitted through a third transmission member, wherein the third transmission member is composed of a third gear and a first rack, the third gear is fixedly connected to the valve of the regulating valve 606, and the first rack is fixedly connected to the telescopic part of the electric telescopic rod 605. The pressure on the pressure sensor 603 is linearly related to the length of the telescopic part of the electric telescopic rod 605. The greater the pressure on the pressure sensor 603, the longer the distance of the telescopic part of the electric telescopic rod 605. Taking the upper side regulating valve 606 as an example, the greater the amplitude of the counterclockwise rotation of the valve of the regulating valve 606, the smaller its flow rate.

[0027] The specific working principle is as follows: In the process of clamping the lens, the limit plate 2 drives the squeezing pin 601 to rotate, so that the squeezing pin 601 squeezes the squeezing block 604 to move downward. At this time, the operator turns on the pressure sensor 603 through the control terminal, and the squeezing block 604 squeezes the telescopic part of the elastic telescopic rod 602 through the pressure sensor 603, so that the telescopic part of the elastic telescopic rod 602 contracts and accumulates force. Taking the processing of small-diameter lenses as an example, the smaller the diameter of the lens, the greater the rotation amplitude of the limit plate 2, the greater the downward movement distance of the squeezing block 604, and the stronger the force accumulated in the telescopic part of the elastic telescopic rod 602, so that the pressure sensor 603 is subjected to a greater squeezing force, and the pressure sensor 603 sends a signal to the control terminal. Instruction, the control terminal controls the telescopic part of the electric telescopic rod 605 to extend longer, and the telescopic part of the electric telescopic rod 605 drives the valve of the regulating valve 606 to rotate through the third transmission member, so that the flow rate of the regulating valve 606 is reduced, thereby making the flow rate of the polishing liquid in the conduit between the liquid storage tank 501 and the nozzle 503 smaller, and the amount of polishing liquid sprayed from the nozzle 503 is less. There is no need to measure the diameter of the lens in advance, so that the self-adjustment of the amount of polishing liquid used when polishing lenses of different diameters can be achieved, avoiding the waste caused by excessive use of polishing liquid when the lens diameter is small, and preventing the poor polishing effect caused by insufficient use of polishing liquid when the lens diameter is large, thereby ensuring the polishing effect of the lens.

[0028] During the rotation of the limit plate 2, the rotation amplitude of the output shaft of the third motor 502 is adjusted according to the extrusion force exerted on the pressure sensor 603, thereby changing the rotation amplitude of the nozzle 503. The larger the diameter of the lens, the larger the rotation amplitude of the nozzle 503, so that the polishing liquid sprayed by the nozzle 503 falls accurately on the surface of the lens, reducing the waste of polishing liquid.

[0029] Before starting to polish the lens, the operator turns off the pressure sensor 603 and the electrically controlled telescopic rod 605 through the control terminal. After the lens is polished, the operator controls the telescopic end of the electrically controlled telescopic rod 605 to move and reset through the control terminal. The telescopic end of the electrically controlled telescopic rod 605 drives the valve of the regulating valve 606 to rotate and reset through the third transmission member.

[0030] like Figure 7-Figure 9As shown, it also includes: an adjustment plate 7, which has two holes, which are respectively fixed to adjacent liquid storage tanks 501, and the adjustment plate 7 is provided with arc-shaped holes 701. The nozzle 503 is sealed and slidably connected to the adjustment plate 7, and the nozzle 503 is connected to the adjacent hole 701. The aperture of a single hole 701 gradually increases from close to the rotating disk 3 to far away, which is used to relieve the pressure of the polishing liquid sprayed by the nozzle 503 to reduce the degree of splashing of the polishing liquid. The apertures of all holes 701 on the same adjustment plate 7 increase in sequence from close to the center of the rotating disk 3 to far away, so that the closer to the center of the rotating disk 3, the less polishing liquid is sprayed by the nozzle 503, and the nozzle 5 03 has an outer diameter A, an inner diameter of the nozzle 503 is B, and an aperture of the hole 701 is C, A-B>C, so that the nozzle 503 and the adjustment plate 7 are always sealed, the inner diameter of the lower nozzle 503 is larger than the inner diameter of the upper nozzle 503, and the aperture of the lower hole 701 is larger than the aperture of the corresponding hole 701 on the upper side. Under the same state, the amount of polishing liquid sprayed by the lower nozzle 503 is larger than the amount of polishing liquid sprayed by the upper nozzle 503. The upper polishing liquid is easy to accumulate on the lens surface, while the lower polishing liquid is not easy to remain on the lens surface. By adjusting the spray amount of the polishing liquid on the upper and lower sides, the amount of polishing liquid on the upper and lower surfaces of the lens is relatively uniform.

[0031] The specific working principle is as follows: When the nozzle 503 rotates and sprays the polishing liquid, the nozzle 503 slides along the adjustment plate 7, so that the nozzle 503 is connected with the holes 701 of different apertures in sequence. When the nozzle 503 sprays the polishing liquid to the edge of the lens, the nozzle 503 is aligned with the hole 701 with a larger aperture. When the nozzle 503 sprays the polishing liquid to the center of the lens, the nozzle 503 is aligned with the hole 701 with the smallest aperture, so that the amount of polishing liquid sprayed by the nozzle 503 is less as it moves toward the center of the lens, so as to adapt to the different polishing areas of the inner and outer circles of the lens (the lens is divided into several circles from its center to the edge, and the surface area of ​​the circle closer to the center is smaller, and the less polishing liquid is needed closer to the center during the polishing process), thereby improving the uniformity of the lens polishing and further improving the accuracy of the lens after polishing.

[0032] like Fig.10 As shown, it also includes: two sliding plates 9, which are slidably connected to adjacent liquid storage tanks 501 respectively, and the sliding plate 9 is provided with a plurality of flow holes. The sliding plate 9 and the rotating shaft of the output shaft on the third motor 502 are transmitted through a fourth transmission member, wherein the fourth transmission member is composed of a fourth gear and a second rack, the fourth gear is fixedly connected to the rotating shaft of the output shaft on the third motor 502, and the second rack is fixedly connected to the sliding plate 9.

[0033] The specific working principle is as follows: During the rotation of the output shaft on the third motor 502, the rotating shaft of the output shaft on the third motor 502 drives the sliding plate 9 to slide back and forth through the fourth transmission member, and the polishing liquid in the liquid storage tank 501 flows through the flow hole of the sliding plate 9. The sliding plate 9 drives the polishing liquid in the liquid storage tank 501 to flow. Through the movement of the sliding plate 9, the polishing liquid in the liquid storage tank 501 continues to flow during use to prevent the particle abrasive in the polishing liquid from being deposited, thereby reducing the amount of particle abrasive in the polishing liquid sprayed from the nozzle 503, thereby affecting the use effect of the polishing liquid and affecting the normal polishing of the lens.

[0034] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
