Description

Technical Field

[0001] This invention relates to the field of lens polishing technology, and more specifically, to a polishing apparatus for the production of optical lenses. Background Technology

[0002] Optical lenses are components used to control the direction of light propagation, focus light rays, or scatter light rays. They are widely used in various optical systems, such as eyeglasses, 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 precision of the optical lens.

[0003] Current optical lens polishing methods typically involve attaching and fixing one side of the lens with adhesive, and then polishing the other side using a polishing pad. This method cannot polish both sides of the lens simultaneously, which means that after polishing one side, the lens needs to be replaced for a second polishing. Furthermore, after polishing, the side with adhesive residue needs to be cleaned. If there are any tiny depressions on the lens surface during the cleaning process, adhesive residue will remain in these depressions, resulting in spots on the lens during use and affecting its precision. Summary of the Invention

[0004] In order to overcome the shortcomings described in the background art, the present invention provides a polishing apparatus for the production of optical lenses.

[0005] The technical solution is: a polishing apparatus for optical lens production, comprising:

[0006] A worktable, wherein two drive arms are mounted on the worktable and are distributed vertically, and a polishing disc is fixedly connected to each drive arm;

[0007] A rotating disk is rotatably connected to the worktable. The rotating disk is slidably connected to a plurality of clamping rods distributed circumferentially. The worktable is equipped with a second motor. The rotating disk and the output shaft of the second motor are driven by a second transmission component.

[0008] A guide assembly is disposed on the worktable, and the guide assembly is used to drive all the clamping rods to move.

[0009] The liquid injection assembly has two parts, which are located on the worktable near different drive arms, and are used to spray polishing liquid onto the lens surface.

[0010] Furthermore, the guiding component includes:

[0011] A limiting plate is rotatably connected to the worktable and located between the two polishing plates. The limiting plate is fixed with circumferentially distributed limiting frames in the same number as the clamping rods. The clamping rods slide within adjacent limiting frames. The worktable is equipped with a first motor. The limiting plate and the output shaft of the first motor are driven by a first transmission component. The limiting plate is provided with arc-shaped limiting holes.

[0012] A limiting pin is slidably connected to the rotating disk and the adjacent limiting hole, and an elastic element is fixedly connected between the limiting pin and the rotating disk.

[0013] Furthermore, the injection assembly includes:

[0014] A liquid storage tank is fixed to the workbench and connected to an external liquid supply device;

[0015] A third motor is fixedly connected to the worktable. The output shaft of the third motor is fixedly connected to a nozzle via a rotating shaft. The liquid storage tank and the nozzle are connected by a conduit.

[0016] Furthermore, it also includes:

[0017] A compression pin is fixed to the side of the limiting plate away from the rotating plate;

[0018] An elastic telescopic rod is fixedly connected to the worktable near the extrusion pin, and a pressure sensor is fixedly connected to the telescopic part of the elastic telescopic rod.

[0019] A compression block is slidably connected to the fixed part of the elastic telescopic rod, and the compression pin is used to compress the compression block, which in turn is used to compress the pressure sensor.

[0020] An electrically controlled telescopic rod is fixedly connected to the workbench;

[0021] A regulating valve is installed on the conduit between the liquid storage tank and the nozzle, and the telescopic part of the electrically controlled telescopic rod is connected to the regulating valve through a third transmission component.

[0022] Furthermore, the distance between the extrusion block and the limiting disk gradually shortens along the direction of rotation of the rotating disk.

[0023] Furthermore, it also includes:

[0024] There are two regulating plates, which are respectively fixed to the adjacent liquid storage tanks. The regulating plates are provided with arc-shaped holes. The nozzle is slidably connected to the regulating plates and communicates with the adjacent holes. The diameter of a single hole gradually increases from the point near the rotating disk to the point far away.

[0025] Furthermore, the diameter of all the holes on the same adjustment plate increases sequentially from the center of the rotating disk to the furthest point.

[0026] Furthermore, the outer diameter of the nozzle is A, the inner diameter of the nozzle is B, and the diameter of the hole is C, where A - B > C.

[0027] Furthermore, the inner diameter of the lower nozzle is larger than the inner diameter of the upper nozzle, and the diameter of the lower hole is larger than the diameter of the corresponding upper hole.

[0028] Furthermore, it also includes:

[0029] There are two sliding plates, which are slidably connected to adjacent liquid storage tanks respectively. The sliding plates are connected to the rotating shaft of the output shaft of the third motor through a fourth transmission component.

[0030] The beneficial effects of the above technical solution are as follows: 1. The present invention achieves clamping of lenses of different sizes by using circumferentially distributed clamping rods, changing the existing form of fixing lenses with glue, and using two polishing discs to polish the upper and lower sides of the lens at the same time, improving the polishing efficiency of the lens, while preventing the lens surface from having spots due to glue residue on the other side after one side of the lens is polished, thus affecting the accuracy of the lens during use.

[0031] 2. The lens diameter is automatically determined by the change in the pressing position of the extrusion pin on the extrusion block, and the amount of polishing liquid required for different diameter lenses is automatically adjusted by the change in the flow rate of the regulating valve. There is no need to measure the lens diameter in advance, so the amount of polishing liquid used when polishing lenses of different diameters can be automatically adjusted. This avoids the waste caused by using too much polishing liquid when the lens diameter is small, and at the same time prevents the polishing effect from being poor due to insufficient polishing liquid when the lens diameter is large, thus ensuring the polishing effect of the lens.

[0032] 3. By setting holes of different diameters, the nozzle is connected to holes of different diameters in sequence, so that the more the nozzle is towards the center of the lens, the less polishing liquid is sprayed, so as to adapt to the different polishing areas of the inner and outer rings of the lens, thereby improving the uniformity of lens polishing and thus improving the precision of the polished lens.

[0033] 4. By moving the sliding plate, the polishing liquid in the storage tank is kept flowing during use to prevent the abrasive particles in the polishing liquid from settling, which would reduce the amount of abrasive particles in the polishing liquid sprayed from the nozzle, thus affecting the effectiveness of the polishing liquid and the normal polishing of the lens.

Detailed Implementation

[0045] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0046] A polishing apparatus for optical lens production, such as Figures 1-6As shown, the system includes: a worktable 1, on which two drive arms 101 are mounted vertically; a control terminal (not shown in the figure) is provided on the worktable 1; both drive arms 101 are electrically connected to the control terminal; polishing discs 102 are fixedly connected to opposite sides of the vertically mounted drive arms 101; both drive arms 101 and polishing discs 102 are existing structures; the drive arms 101 are used to drive the polishing discs 102 on them to reciprocate, so that the polishing discs 102 polish and grind the lens; a rotating disk 3, rotatably connected to the worktable 1; a plurality of circumferentially distributed clamping rods 301 are slidably connected to the rotating disk 3; a second motor 302 electrically connected to the control terminal is mounted on the worktable 1; and the rotating disk 3 and the output shaft of the second motor 302 are connected by a... The system employs a two-transmission mechanism, comprising a second gear and a second gear ring. The transmission ratio between the first gear and the first gear ring is X, and the transmission ratio between the second gear and the second gear ring is Y, where X = Y. The output shafts of the first motor 202 and the second motor 302 operate at the same speed, allowing the limiting disk 2 and the rotating disk 3 to rotate synchronously. The second gear is fixedly connected to the output shaft of the second motor 302, and the second gear ring is fixedly connected to the rotating disk 3. A guide assembly is mounted on the worktable 1 and is used to move all clamping rods 301. Two liquid injection assemblies 5 are located on the worktable 1 near different drive arms 101 and are used to spray polishing liquid onto the lens surface. The polishing liquid is a mixture of liquid and abrasive particles.

[0047] like Figures 1-6 As shown, the guide assembly includes: a limiting disk 2, rotatably connected to the worktable 1 and located between two polishing disks 102; the limiting disk 2 is fixedly connected with circumferentially distributed limiting frames 201, the number of which is the same as the number of clamping rods 301; the clamping rods 301 slide within adjacent limiting frames 201; the limiting frames 201 are arc-shaped, so as to... Figure 1 The top view is the rotation reference. When the limiting disk 2 drives all the limiting frames 201 to rotate counterclockwise, the clamping rod 301 moves along the adjacent limiting frames 201 towards the center of the limiting disk 2. The worktable 1 is equipped with a first motor 202 that is electrically connected to the control terminal. The limiting disk 2 and the output shaft of the first motor 202 are connected by a first transmission component, which consists of a first gear and a first gear ring. The first gear is fixedly connected to the output shaft of the first motor 202, and the first gear ring is fixedly connected to the limiting disk 2. The limiting disk 2 is provided with arc-shaped limiting holes 401. The limiting pin 4 is slidably connected to the rotating disk 3 and the adjacent limiting holes 401. An elastic element is fixedly connected between the limiting pin 4 and the rotating disk 3. The elastic element is a tension spring. When the limiting pin 4 is located in the adjacent limiting hole 401, the elastic element of the limiting pin 4 is in the initial unstretched state.

[0048] like Figure 3 , Figure 7 and Figure 8As shown, the liquid injection assembly 5 includes: a liquid storage tank 501, which is fixed to the workbench 1 and connected to an external liquid supply device, which is electrically connected to a control terminal; a third motor 502, which is fixed to the workbench 1 and electrically connected to the control terminal; the output shaft of the third motor 502 is fixed to a nozzle 503 via a rotating shaft; the liquid storage tank 501 and the nozzle 503 are connected by a conduit; the liquid storage tank 501, the nozzle 503, and the conduit between them are all made of stainless steel to reduce the corrosive effect of alkaline substances in the polishing liquid.

[0049] The specific working principle is as follows:

[0050] When this device is needed to polish an optical lens (hereinafter referred to as the lens), the operator places the lens between all the clamping rods 301, and then pulls the limit pin 4 upward, causing the elastic element of the limit pin 4 to stretch. The operator starts the first motor 202 through the control terminal. The output shaft of the first motor 202 drives the limit plate 2 to rotate counterclockwise through the first transmission component. The limit plate 2 drives all the limit frames 201 on it to rotate. The limit frames 201 squeeze the clamping rods 301, so that the circumferentially distributed clamping rods 301 move towards the center of the limit plate 2. When all the clamping rods 301 have moved 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.

[0051] After the lens is fixed, the operator starts the second motor 302 through the control terminal. The output shaft of the second motor 302 drives the rotating disk 3 to rotate through the second transmission component. The rotating disk 3 drives the limiting disk 2 to rotate through the limiting pin 4. At the same time, the operator starts the first motor 202 again through the control terminal. The output shaft of the first motor 202 drives the limiting disk 2 to rotate through the first transmission component. The limiting disk 2 and the rotating disk 3 together drive all the clamping rods 301 to rotate, so that the lens rotates. At this time, the operator starts the upper and lower drive arms 101 through the control terminal. The two drive arms 101 drive the adjacent polishing disks 102 to swing horizontally, polishing the upper and lower surfaces of the lens respectively. By polishing the upper and lower surfaces of the lens at the same time, the polishing efficiency of the lens is improved, and it is prevented that after one side of the lens is polished, the other side will have spots on the lens surface due to glue residue, which would affect the accuracy of the lens during use.

[0052] 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 delivers polishing liquid to the storage tank 501. The polishing liquid in the 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. This process is repeated so that the polishing liquid is sprayed to all parts of the lens to assist the polishing disc 102 in polishing the lens surface.

[0053] After the lens polishing is completed, the operator shuts down the drive arm 101, the first motor 202, the second motor 302, the external liquid supply device, and the third motor 502 via the control terminal. Then, the operator pulls out the limit pin 4 from the corresponding limit hole 401 and controls the output shaft of the first motor 202 to rotate in the reverse direction via the control terminal. The output shaft of the first motor 202 drives the limit plate 2 to rotate clockwise through the first transmission component, causing all the limit frames 201 to press the adjacent clamping rods 301 to move. The clamping rods 301 move and lose their clamping on the lens. The operator removes the lens for collection and releases the limit pin 4. The elastic element of the limit pin 4 springs back to its original position, allowing the limit pin 4 to insert into the corresponding limit hole 401. Finally, the device is cleaned for the next use.

[0054] like Figures 4-6 and Figure 8 As shown, it also includes: a pressing pin 601, fixedly connected to the lower side of the limiting plate 2; an elastic telescopic rod 602, fixedly connected to the worktable 1 near the pressing pin 601, with a pressure sensor 603 fixedly connected to the telescopic part of the elastic telescopic rod 602, the pressure sensor 603 being 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; and a pressing block 604, slidably connected to the fixed part of the elastic telescopic rod 602, the pressing pin 601 being used to press the pressing block 604, and the pressing block 604 being used to press the pressure sensor 603, so that... Figure 1From the top view with the rotation direction as the reference, the distance between the extrusion block 604 and the limiting plate 2 gradually shortens in the counterclockwise direction; the electrically controlled telescopic rod 605 is fixed to the workbench 1 and 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. The regulating valve 606 is equipped with a valve. The telescopic part of the electrically controlled telescopic rod 605 and the valve of the regulating valve 606 are connected by a third transmission component, which consists of a third gear and a first rack. The third gear is fixed to the valve of the regulating valve 606, and the first rack is fixed to the telescopic part of the electrically controlled telescopic rod 605. The pressure on the pressure sensor 603 is linearly related to the extension length of the telescopic part of the electrically controlled telescopic rod 605. The greater the pressure on the pressure sensor 603, the longer the extension distance of the telescopic part of the electrically controlled telescopic rod 605. Taking the upper regulating valve 606 as an example, the greater the counterclockwise rotation amplitude of the regulating valve 606, the smaller its flow rate.

[0055] The specific working principle is as follows:

[0056] During the lens clamping process, the limiting disc 2 drives the pressing pin 601 to rotate, causing the pressing pin 601 to press the pressing block 604 downwards. At this time, the operator activates the pressure sensor 603 through the control terminal. The pressing block 604, through the pressure sensor 603, presses the telescopic part of the elastic telescopic rod 602, causing the telescopic part of the elastic telescopic rod 602 to contract and store force. Taking the processing of small-diameter lenses as an example, the smaller the lens diameter, the greater the rotation amplitude of the limiting disc 2, the greater the downward distance of the pressing block 604, and the stronger the force stored in the telescopic part of the elastic telescopic rod 602. This results in a greater compressive force on the pressure sensor 603, which then sends a signal to the control terminal. The command, controlled by the control terminal, extends the telescopic part of the electrically controlled telescopic rod 605 a longer distance. The telescopic part of the electrically controlled telescopic rod 605 drives the valve of the regulating valve 606 to rotate through the third transmission component, thereby reducing the flow of the regulating valve 606. This results in a smaller flow of polishing liquid in the conduit between the liquid storage tank 501 and the nozzle 503, and a smaller amount of polishing liquid sprayed by the nozzle 503. Without the need to measure the lens diameter in advance, the amount of polishing liquid used can be automatically adjusted when polishing lenses of different diameters. This avoids waste caused by excessive use of polishing liquid when the lens diameter is small, and at the same time prevents poor polishing effect due to insufficient polishing liquid when the lens diameter is large, thus ensuring the polishing effect of the lens.

[0057] During the rotation of the limiting disk 2, the rotation amplitude of the output shaft of the third motor 502 is adjusted according to the squeezing force received by the pressure sensor 603, thereby changing the rotation amplitude of the nozzle 503. The larger the lens diameter, the greater the rotation amplitude of the nozzle 503, so that the polishing liquid sprayed by the nozzle 503 falls accurately on the lens surface, reducing the waste of polishing liquid.

[0058] Before polishing the lens, the operator shuts off the pressure sensor 603 and the electrically controlled telescopic rod 605 via the control terminal. After the lens polishing is completed, the operator controls the telescopic end of the electrically controlled telescopic rod 605 to move and reset via 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 via the third transmission component.

[0059] like Figures 7-9 As shown, it also includes: two adjusting plates 7, each fixed to an adjacent storage tank 501; the adjusting plates 7 are provided with arc-shaped distributed holes 701; the nozzle 503 is slidably connected to the adjusting plates 7; the nozzle 503 communicates with the adjacent holes 701; the diameter of a single hole 701 gradually increases from near the rotating disk 3 to far away, used to depressurize the polishing liquid sprayed by the nozzle 503 to reduce the degree of polishing liquid splashing; the diameter of all holes 701 on the same adjusting plate 7 increases sequentially from near 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; the nozzle 503... The outer diameter of nozzle 503 is A, the inner diameter of nozzle 503 is B, and the aperture of hole 701 is C, where A - B > C, so that nozzle 503 and adjusting plate 7 are always sealed. The inner diameter of the lower nozzle 503 is larger than that of the upper nozzle 503, and the aperture of the lower hole 701 is larger than that of the corresponding upper hole 701. Under the same conditions, the amount of polishing liquid sprayed by the lower nozzle 503 is greater than that sprayed by the upper nozzle 503. The polishing liquid on the upper side is easy to accumulate on the lens surface, while the polishing liquid on the lower side is not easy to stay on the lens surface. By adjusting the spray volume of 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.

[0060] The specific working principle is as follows:

[0061] During the rotation of the nozzle 503 and the spraying of polishing fluid, the nozzle 503 slides along the adjusting plate 7, allowing it to connect sequentially with holes 701 of different diameters. When the nozzle 503 sprays polishing fluid to the edge of the lens, it aligns with the hole 701 with the larger diameter. When the nozzle 503 sprays polishing fluid to the center of the lens, it aligns with the hole 701 with the smallest diameter. This ensures that the amount of polishing fluid sprayed by the nozzle 503 decreases as it approaches the center of the lens, thus adapting to the different polishing areas of the inner and outer rings of the lens (the lens is divided into several rings from its center to the edge; the ring closer to the center has a smaller surface area, and therefore requires less polishing fluid during the polishing process). This improves the uniformity of lens polishing and, consequently, the precision of the polished lens.

[0062] like Figure 10As shown, it also includes: two sliding plates 9, which are slidably connected to adjacent liquid storage tanks 501 respectively. The sliding plates 9 are provided with several flow holes. The sliding plates 9 are connected to the output shaft of the third motor 502 through a fourth transmission component. The fourth transmission component consists of a fourth gear and a second rack. The fourth gear is fixedly connected to the output shaft of the third motor 502, and the second rack is fixedly connected to the sliding plates 9.

[0063] The specific working principle is as follows:

[0064] During the rotation of the output shaft of the third motor 502, the shaft of the output shaft of the third motor 502 drives the sliding plate 9 to slide back and forth through the fourth transmission component. The polishing liquid in the storage tank 501 flows through the flow hole of the sliding plate 9. The sliding plate 9 drives the polishing liquid in the storage tank 501 to flow. Through the movement of the sliding plate 9, the polishing liquid in the storage tank 501 flows continuously during use to prevent the abrasive particles in the polishing liquid from depositing, which would reduce the amount of abrasive particles in the polishing liquid sprayed by the nozzle 503, thereby affecting the use effect of the polishing liquid and affecting the normal polishing of the lens.

[0065] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
