Description

Technical Field

[0001] The present invention relates to the technical field of optical lens coating, and in particular to an optical lens coating method and system. Background Art

[0002] An optical lens is an optical element that can change the direction of light propagation and is usually made of transparent materials such as glass or plastic. Optical lenses refract light through their specific shape and refractive index, thereby focusing or dispersing the light.

[0003] The production of optical lenses requires multiple steps including:

[0004] Cutting: cutting the initial optical glass or resin into blanks of appropriate size according to the designed dimensions; common cutting methods include mechanical cutting and laser cutting;

[0005] Grinding is the rough processing of the cut optical blank to remove burrs and surface unevenness caused by cutting. Grinding fluid and grinding tools are usually used; grinding tools include grinding discs, grinding paper, etc.

[0006] Polishing is the finishing of optical blanks based on grinding to improve surface smoothness; polishing fluid and polishing tools such as polishing discs and polishing cloths are used;

[0007] Edge grinding: precisely grinding the outer diameter of the lens to meet the specified size requirements to ensure that the lens can accurately fit the corresponding equipment;

[0008] Cleaning: After the polishing process, the polishing powder and other impurities remaining on the lens surface must be thoroughly removed to prevent quality problems during the subsequent assembly of optical equipment;

[0009] Coating uses a vacuum coating machine to coat one or more layers of thin films with a thickness of micrometer to nanometer on the surface of the optical lens through physical or chemical methods to change the optical properties of the lens.

[0010] Among them, when optical lenses are used in a vacuum coating machine, a tray-mounted coating tray is used, and specifically the optical lens is placed on the coating tray; during the coating process, metals, oxides and other materials need to be vaporized or ionized and then deposited on the lens surface; in this process, in order to prevent vaporized particles from splashing, and when the evaporation source heats the material, tiny droplets or particles may splash onto the surface of the optical lens, so a shielding object is needed to shield the uncoated side of the optical lens; after one side of the optical lens is coated, when the other side is coated, the staff needs to take out the coating tray and then take out the shielding object, and then remove the optical lens from the coating tray or turn it over, and then cover the coating tray with the shielding object; this process is relatively cumbersome, and the coating tray needs to be removed from the vacuum coating machine, and the coating efficiency is low.

[0011] In order to improve the above-mentioned technical problems, the present application proposes a method and system for coating an optical lens. Summary of the Invention

DETAILED DESCRIPTION

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0042] Example 1:

[0043] like Figures 1 to 12 As shown; an optical lens coating system, the coating system is an optical lens coating machine, the optical lens coating machine includes a body 1, a drive motor 11 and a telescopic device 12; the drive motor 11 is arranged at the upper end of the body 1, and the telescopic device 12 is located at the lower part of the body 1; it is characterized in that it also includes:

[0044] The rotating disk 13 is installed inside the upper end of the body 1 and is connected to the driving motor 11 on the body 1. The lower end of the rotating disk 13 is annularly provided with a plurality of mounting grooves 131.

[0045] The placing plate 14 has one end hinged to the inside of the mounting slot 131; the other end is initially vertically downward, and a plurality of placing holes 141 are provided on the placing plate 14; two slide grooves 142 are provided on the outer side of the placing plate 14, and the two slide grooves 142 are located on both sides of the placing hole 141. A slide plate 143 is slidably connected to the inside of each slide groove 142 by a spring, and a reel 144 is rotatably connected between the two slide plates 143 via a rotating shaft. A torsion spring is sleeved between the reel 144 and the rotating shaft, and a paper roll 145 is wound on the reel 144. One end of the paper roll 145 is fixed to the end of the placing plate 14 away from the rotating disk 13, and the slide plates 143 on adjacent placing plates 14 are connected by a steel rope 146;

[0046] The telescopic column 15 is disposed at the center of the lower end of the rotating disk 13. A drive disk 151 is disposed at the lower end of the telescopic column 15. A plurality of drive grooves 152 are annularly distributed on the outer side of the upper end of the drive disk 151. A drive rod 153 is hingedly connected to the inner side of the upper end of the driving groove 152. The other end of the drive rod 153 is hingedly connected to the inner side of the upper end of the placement plate 14. The drive disk 151 is located directly above the telescopic device 12.

[0047] A fixing plate 147 is provided at one end of the two slide plates 143 close to the rotating disk 13 , and a rubber strip 148 is provided between the fixing plates 147 . The rubber strip 148 contacts the outer side of the placement plate 14 .

[0048] The specific workflow is as follows:

[0049] When coating an optical lens, the hatch on the vacuum coating machine is first opened to expose the rotating disk 13 and the placement plate 14 inside the machine body 1. The worker then installs the optical lens to be coated in the placement hole 141 on the placement plate 14. During the placement process, the worker can control the driving motor 11 on the machine body 1 to rotate slowly. After the optical lens is installed on one placement plate 14, the other placement plates 14 are rotated to a position convenient for installing the optical lens.

[0050] After all the placement plates 14 are installed, the staff controls the telescopic device 12 to work. The telescopic device 12 can be an electric telescopic cylinder in the prior art. When the telescopic device 12 is working, the output end of the telescopic device 12 moves upward. Since the driving disk 151 at the lower end of the telescopic column 15 is located directly above the telescopic device 12, the upward movement of the output end of the telescopic device 12 will push the driving disk 151 at the lower end of the telescopic column 15. After the driving disk 151 is pushed by the telescopic device 12, the driving disk 151 pushes the telescopic column 15 to retract toward the inside of the rotating disk 13.

[0051] Since in the initial state, the multiple placement plates 14 are vertically downward, and the telescopic column 15 is in a state of extending in the rotating disk 13, at this time, the driving rod 153 outside the driving disk 151 and the placement plate 14 are in an inclined state, so that the driving disk 151, the telescopic column 15, the driving rod 153 and the placement plate 14 form an umbrella rib structure in the prior art; so when the driving disk 151 pushes the telescopic column 15 to move upward, the driving disk 151 drives the driving rod 153 to move, and the driving rod 153 approaches the direction of the rotating disk 13. During the process, since the length of the driving rod 153 remains unchanged, the end of the driving rod 153 away from the driving disk 151 will move toward the outside of the rotating disk 13. During the process, the driving rod 153 is hinged at one end of the placement plate 14, which pushes the placement plate 14, and one end of the placement plate 14 is hinged on the rotating disk 13, so that the placement plate 14 rotates, and the placement plate 14 gradually opens from a vertical downward state, and the end of the placement plate 14 away from the rotating disk 13 approaches the inner wall of the body 1. The working state of the placement plate 14 is similar to the opening of the ribs of an umbrella. Then the driving motor 11 works, and the driving motor 11 drives the rotating disk 13 to rotate. The telescopic column 15 at the lower end of the rotating disk 13 and the driving disk 151 rotate synchronously. At the same time, the placement plate 14 and the driving rod 153 rotate synchronously, and the optical lens at the lower end of the opened placement plate 14 is coated;

[0052] During the opening of the above-mentioned placing plate 14, since two sliding grooves 142 are provided on the outer side of the placing plate 14, multiple placing holes 141 are located between the two sliding grooves 142, and a slide plate 143 is slidably connected inside the slide groove 142. A reel 144 is rotatably connected between the two slide plates 143 through a rotating shaft, and a paper roll 145 is sleeved on the reel 144. The material of the paper roll 145 is a silicone sheet, and one end of the paper roll 145 is fixed to the end of the placing plate 14 away from the rotating disk 13, and the adjacent slide plates 143 on each placing plate 14 are connected by a steel rope 146. When multiple placing plates 14 are opened, The end of the placement plate 14 away from the rotating disk 13 will move away from each other. At this time, the distance between the multiple slides 143 on the end of the placement plate 14 away from the rotating disk 13 becomes larger, but the distance between the slides 143 on the multiple placement plates 14 is connected by the steel rope 146 and cannot move away from each other. Therefore, due to the squeezing of the placement plate 14 when it is opened, the slide 143 will slide inside the chute 142 toward the end close to the rotating disk 13. During this process, since one end of the paper roll 145 is fixed, the reel 144 will rotate to unwind the paper roll 145. The reel 144 and the rotating shaft are hinged by a torsion spring, which compresses the torsion spring between the reel 144 and the rotating shaft.

[0053] When the slide 143 drives the reel 144 to move on the placement plate 14 toward the rotating disk 13, the paper roll 145 is unwound to cover the placement hole 141 on the placement plate 14, thereby making the paper roll 145 cover the optical lens inside the placement hole 141, until the slide 143 moves to the end of the chute 142 close to the rotating disk 13, the paper roll 145 completely covers the placement hole 141 on the placement plate 14, so that after the placement plate 14 is opened, the paper roll 145 also covers the end of the optical lens that does not need to be coated temporarily, and when the slide 143 moves in the direction of the rotating disk 13, the slide 143 is close to the fixed plate 14 set at one end of the rotating disk 13. 7, and the rubber strip 148 between the two fixed plates 147 moves synchronously toward the rotating disk 13. During this process, the rubber strip 148 will contact the side of the optical lens that does not need to be coated temporarily one by one, and then the rubber strip 148 moves to scrape and clean its surface, so as to avoid residual fingerprints or dust impurities on the surface of the optical lens when the staff installs the optical lens. Then the driving motor 11 works, and the placement plate 14 is driven to rotate through the rotating disk 13 to coat the optical lens; during this process, the roll paper 145 covers the side of the optical lens that does not need to be coated temporarily, so as to avoid the splashing of vaporized particles and the splashing of tiny droplets or particles onto the surface of the optical lens when the evaporation source heats the material;

[0054] When the coating is completed, the telescopic device 12 is reset, and the telescopic device 12 no longer pushes the drive disk 151 and the telescopic column 15, so that the drive disk 151 and the telescopic column 15 are reset. During the process, the end of the placement plate 14 away from the rotating disk 13 rotates downward, so that the end of the placement plate 14 away from the rotating disk 13 approaches each other; at the same time, the spring inside the slide groove 142 elastically resets, so that the slide plate 143 slides toward the end away from the rotating disk 13. During the process, the torsion spring elastically resets on the rotating shaft, so that the reel 144 rotates on the rotating shaft, and the reel 144 rewinds the roll paper 145; then the staff opens the cabin door to take out the optical lens; during the process, the staff does not need to take out the covering, so as to improve the coating efficiency of the optical lens;

[0055] It is worth noting that the reel 144 and the paper roll 145 are movably installed. The paper roll 145 is fixed on the placement plate 14 by using a pressure plate. At the same time, the reel 144 can also be disassembled on the rotating shaft between the slides 143, so that the paper roll 145 can be easily replaced before its life is about to end.

[0056] Example 2:

[0057] like Figures 3 to 12 As shown; a support plate 16 is fixed to the end of the placement plate 14 close to the rotating disk 13. The gap between the end of the support plate 16 away from the rotating disk 13 and the placement plate 14 is greater than the height of the slide plate 143. The end of the support plate 16 away from the rotating disk 13 is hinged with a claw 161 through a torsion spring. The claw 161 has a U-shaped structure. When the slide plate 143 moves, the fixed plate 147 and the reel 144 pass over the gap between the claw 161 and the placement plate 14, and the fixed plate 147 squeezes the end of the claw 161 close to the placement plate 14.

[0058] A rubber column 162 is provided at one end of the clamping claw 161 away from the placement plate 14 .

[0059] The specific workflow is as follows:

[0060] When the roller 144 moves to the side of the slide groove 142 close to the rotating disk 13, the end of the support plate 16 away from the rotating disk 13 is hinged to the claw 161 by the torsion spring, so that the claw 161 is in a U-shaped structure. When the slide plate 143 moves toward the end of the slide groove 142 close to the rotating disk 13, the fixed plate 147 on the slide plate 143 moves synchronously, and the end of the fixed plate 147 close to the rotating disk 13 will squeeze the end of the claw 161 close to the surface of the placing plate 14. In this process, since the distance between the end of the claw 161 away from the surface of the placing plate 14 is greater than the height of the slide plate 143, in the initial state, the distance between the end of the claw 161 away from the placing plate 14 and its surface is greater than the maximum distance between the roller 144 and the placing plate 14. At the same time, when the roller 144 moves to the side of the slide groove 142 close to the rotating disk 13, the roller 144 is in the unwinding state, satisfying the roller 144 passing through the The paper roll 145 is pressed against the paper roller 144 by the end of the clamping claw 161 away from the surface of the placing plate 14 and the placing plate 14, thereby preventing the paper roller 144 from entering the U-shaped structure of the clamping claw 161. During the process, the fixed plate 147 squeezes the end of the clamping claw 161 close to the placing plate 14, and the clamping claw 161 rotates, so that the end of the clamping claw 161 away from the surface of the placing plate 14 gradually approaches the surface of the placing plate 14, until the end of the clamping claw 161 away from the surface of the placing plate 14 squeezes the paper roll 145 on the rear side of the roll 144; after the paper roll 145 covers the optical lens, the two ends of the paper roll 145 are limited; after the paper roll 145 covers the optical lens, there is a gap between the end of the paper roll 145 close to the rotating disk 13 and the surface of the placing plate 14, which causes the end of the paper roll 145 close to the rotating disk 13 to be unstable when the rotating disk 13 rotates; and the squeezing end of the end of the clamping claw 161 away from the surface of the placing plate 14 squeezing the paper roll 145 is the rubber column 162, which avoids damage to the paper roll 145;

[0061] On the basis of the above-mentioned embodiment 1, when the placement plate 14 is reset, the slide plate 143 is reset synchronously, and the fixed plate 147 on the slide plate 143 gradually stops squeezing the end of the claw 161 close to the surface of the placement plate 14. The torsion spring between the claw 161 and the support plate 16 causes the claw 161 to rotate, and the end of the claw that is away from the surface of the placement plate 14 gradually stops squeezing the roll paper 145. At the same time, the reel 144 reels the roll paper 145 and disengages from between the claws 161 of the U-shaped structure, achieving reset.

[0062] Example 3:

[0063] like Figures 2 to 12As shown; a cylindrical groove 17 is opened between adjacent placement holes 141, and a cylindrical rod 171 is rotatably connected between each cylindrical groove 17; the interior of each placement hole 141 is rotatably connected to a placement ring 172, and the outer side of the placement ring 172 is connected to the cylindrical rod 171 inside the cylindrical groove 17, and the end of the placement plate 14 away from the rotating disk 13 is rotatably connected to a ratchet disk 173, and the outer side of the ratchet disk 173 is a gear structure, and the middle part of the ratchet disk 173 is connected to the cylindrical rod 171 inside the cylindrical groove 17, and a gear ring 174 is provided at the upper end of the interior of the body 1; when the placement plate 14 rotates, the outer side of the ratchet disk 173 engages with the gear ring 174.

[0064] The specific workflow is as follows:

[0065] A cylindrical groove 17 is provided between adjacent placement holes 141, and a cylindrical rod 171 is rotatably connected inside the cylindrical groove 17, and a placement ring 172 is rotatably connected inside the placement hole 141, so that the outer side of the placement ring 172 is connected to the adjacent cylindrical rod 171; when installing an optical lens, the optical lens is installed in the placement ring 172;

[0066] The ratchet disc 173 is rotatably connected to the end of the placement plate 14 away from the rotating disc 13. The outer side of the ratchet disc 173 is a gear structure. The structure of the ratchet disc 173 is the same as the ratchet tooth structure of the ratchet wheel in the prior art, so that the ratchet disc 173 is divided into an inner disc 2 and an outer disc 3. The inner disc 2 of the ratchet disc 173 is connected to the cylindrical rod 171, and the outer disc 3 of the ratchet disc 173 is a gear structure.

[0067] On the basis of the above-mentioned embodiment 1, after the placement plate 14 is opened, the outer side of the ratchet disc 173 at one end of the placement plate 14 away from the rotating disc 13 is meshed with the gear ring 174 fixed to the upper end of the body 1; when the optical lens is coated, the driving motor 11 drives the rotating disc 13 to rotate clockwise. At this time, the rotating disc 13 drives the ratchet disc 173 to move clockwise at the lower end of the gear ring 174. At the same time, the outer disc 3 of the ratchet disc 173 rotates outside the inner disc 2 of the ratchet disc 173. During this process, the inner disc 2 of the ratchet disc 173 and the outer disc 3 of the ratchet disc 173 rotate relative to each other, so that the outer disc 3 of the ratchet disc 173 cannot drive the inner disc 2 of the ratchet disc 173 to rotate; so that the inner disc 2 of the ratchet disc 173 does not drive the cylindrical rod 171 to rotate, and then the placement ring 172 does not drive the optical lens to rotate, and the optical lens is coated during the process;

[0068] After the coating of one side of the optical lens is completed, the staff controls the drive motor 11 to rotate counterclockwise. At this time, the ratchet disc 173 rotates counterclockwise on the lower side of the gear ring 174. During this process, the inner disc 2 and the outer disc 3 of the ratchet disc 173 are engaged with each other, so that the outer disc 3 of the gear disc rotates to drive the inner disc 2 to rotate synchronously. During this process, the inner disc 2 of the ratchet disc 173 drives the cylindrical rod 171 to rotate, and the cylindrical rod 171 drives the placement ring 172 to rotate, and the placement ring 172 drives the optical lens to rotate, so that the coated side of the optical lens The end rotates to the lower end of the paper roll 145, and the paper roll 145 covers it, and the uncoated end of the optical lens rotates to the inner side of the placement plate 14; when the placement ring 172 rotates, the outer side of the placement ring 172 squeezes the paper roll 145. During the process, since the paper roll 145 is not made of silicone sheet material, it has the characteristics of elastic deformation, and the two ends of the paper roll 145 are limited; therefore, during the rotation of the placement ring 172, the paper roll 145 is squeezed and deformed. When the placement ring 172 stops rotating, the paper roll 145 elastically recovers;

[0069] After the placement ring 172 rotates, the counterclockwise rotation of the drive motor 11 is stopped, and the drive motor 11 rotates clockwise. At this time, the inner disk 2 of the ratchet disk 173 and the outer disk 3 of the ratchet disk 173 rotate relative to each other, so that the outer disk 3 of the ratchet disk 173 cannot drive the inner disk 2 of the ratchet disk 173 to rotate, thereby achieving the placement ring 172 being unable to rotate, so that the uncoated side of the optical lens can be coated; thereby achieving the one-time coating of both sides of the optical lens without opening the vacuum coating machine, and in the process, the side not involved in the coating can be covered, thereby improving the coating efficiency.

[0071] like Figures 3 to 12 As shown; the output end of the telescopic device 12 is fixed with a disc 121, and a plurality of support members 122 are distributed annularly on the outer side of the disc 121, and each support member 122 is provided with a cleaning roller 123, which contacts the inner side of the cleaning roller 123 and the placement plate 14;

[0072] A rotating ring 124 is rotatably connected to the center of the upper end of the disk 121 , and the upper end of the rotating ring 124 protrudes from the upper end of the disk 121 .

[0073] The specific workflow is as follows:

[0074] By fixing the disc 121 at the output end of the telescopic device 12, distributing the support member 122 in an annular manner on the outer side of the disc 121, and arranging a cleaning roller 123 on the support member 122, the cleaning roller 123 is in contact with the inner side of the placement plate 14; on the basis of the above-mentioned embodiment 1, when the telescopic device 12 is extended inside the body 1, the output end of the telescopic device 12 will push the disc 121 to move upward, and during the process, the support member 122 on the outer side of the disc 121 moves upward synchronously, so that the cleaning roller 123 moves upward synchronously. Since the cleaning roller 123 contacts the inner side of the placement plate 14, when the cleaning roller 123 moves upward, the surface of the optical lens on the inner side of the placement plate 14 is cleaned; further reducing the impurities on the surface of the optical lens during coating; and by The upper center position of the telescopic device 12 is rotatably connected to the rotating ring 124, so that the upper end of the rotating ring 124 protrudes from the upper end of the disc 121; when the telescopic device 12 is extended, the disc 121 at the upper end of the telescopic device 12 drives the rotating ring 124 to contact the driving disc 151 at the lower end of the telescopic column 15, and the rotating ring 124 at the upper end of the disc 121 contacts the lower end of the driving disc 151; thereby, when the driving motor 11 drives the telescopic column 15 and the driving disc 151 to rotate through the rotating disc 13, the lower end of the driving disc 151 and the disc 121 at the upper end of the telescopic device 12 rotate relative to each other. At this time, since the rotating ring 124 rotatably connected to the upper end of the disc 121 contacts the lower end of the driving disc 151, the rotating ring 124 rotates, thereby reducing the friction between the disc 121 and the driving disc 151.

[0075] Embodiment 5:

[0077] S1: First, the hatch on the vacuum coating machine is opened, and then the staff installs the optical lens to be coated in the placement hole 141 on the placement plate 14. During the placement process, the staff controls the driving motor 11 on the body 1 to rotate slowly, so that after the optical lens is installed on one placement plate 14, the optical lens is installed on the other placement plates 14;

[0078] S2: After all the placement plates 14 are installed, the output end of the telescopic device 12 moves upward to push the drive disk 151 at the lower end of the telescopic column 15. The drive disk 151 drives the drive rod 153 to move, causing the placement plates 14 to gradually open. The slide plate 143 slides inside the chute 142 toward the end close to the rotating disk 13, and the reel 144 unwinds the roll paper 145.

[0079] S3: After the paper roll 145 is unwound, the placement hole 141 on the placement plate 14 is covered, and the synchronous paper roll 145 covers the end of the optical lens that does not need to be coated temporarily, and then the driving motor 11 works, and the placement plate 14 is driven to rotate through the rotating disk 13 to coat the optical lens; during the process, the paper roll 145 covers the side of the optical lens that does not need to be coated temporarily.

[0080] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
