Technical Field

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

[0002] An optical lens is an optical element that can change the propagation direction of light, usually made of transparent materials such as glass or plastic; through its specific shape and refractive index, the optical lens refracts light, thereby achieving the focusing or dispersion of light; Multiple steps are required in the production process of optical lenses, including: Cutting: cutting the initial optical glass or resin and other materials into blanks of appropriate size according to the design dimensions; common cutting methods include mechanical cutting and laser cutting; Grinding: rough machining the cut optical blanks to remove burrs and surface unevenness generated by cutting; usually, grinding fluid and grinding tools are used; the grinding tools include grinding discs, grinding papers, etc.; Polishing: finishing the optical blanks on the basis of grinding to improve the surface smoothness; polishing fluid and polishing tools such as polishing discs, polishing cloths, etc. are used; Edge grinding: precisely grinding the outer diameter of the lens to make it meet the specified size requirements and ensure that the lens can be accurately adapted to the corresponding equipment; Cleaning: after the polishing process, it is necessary to thoroughly remove the residual polishing powder and other impurities on the surface of the lens to prevent quality problems during the subsequent assembly process of optical equipment; Coating: using a vacuum coating machine, coating one or more layers of films with a thickness ranging from micrometers to nanometers on the surface of the optical lens by physical or chemical methods to change the optical properties of the lens.

[0003] During the use of the optical lens in the vacuum coating machine, a disk-shaped coating disk is mostly used, specifically by placing the optical lens on the coating disk; in the coating process of the optical lens, materials such as metals and oxides need to be vaporized or ionized and then deposited on the surface of the lens; during this process, in order to prevent the splashing of vaporized particles and the possible generation of tiny droplets or particles splashing onto the surface of the optical lens when the evaporation source heats the material, a shielding object is required to shield the uncoated side of the optical lens; when one side of the optical lens is coated and then the other side is coated, the staff needs to take out the coating disk, then take out the shielding object, remove or turn over the optical lens from the coating disk after taking it out, and then cover the shielding object on the coating disk again; this process is rather cumbersome and requires removing the coating disk from the vacuum coating machine, resulting in low coating efficiency.

Detailed implementation manners

[0016] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0017] Embodiment 1:

[0018] As Figures 1 to 12 shown; an optical lens coating system, the coating system is an optical lens coating machine, and the optical lens coating machine includes a machine body 1, a drive motor 11 and a telescopic device 12; the drive motor 11 is arranged at the upper end of the machine body 1, and the telescopic device 12 is located below the interior of the machine body 1; characterized in that it further includes: A rotating disk 13, which is installed inside the upper end of the machine body 1 and is connected to the drive motor 11 on the machine body 1; a plurality of mounting grooves 131 are annularly formed at the lower end of the rotating disk 13; The placing plate 14 has one end hinged inside the installation groove 131; the other end is vertically downward in the initial state. A plurality of placing holes 141 are formed in the placing plate 14; two sliding grooves 142 are formed on the outer side of the placing plate 14, and the two sliding grooves 142 are located on both sides of the placing holes 141. A sliding plate 143 is slidably connected inside each sliding groove 142 through a spring. A winding drum 144 is rotatably connected between the two sliding plates 143 through a rotating shaft. A torsion spring is sleeved between the winding drum 144 and the rotating shaft. A roll of paper 145 is wound on the winding drum 144. One end of the roll of paper 145 is fixed to the end of the placing plate 14 away from the rotating disk 13. The sliding plates 143 on adjacent placing plates 14 are connected by a steel cable 146; The telescopic column 15 is arranged at the central position of the lower end of the rotating disk 13. A driving disk 151 is arranged at the lower end of the telescopic column 15. A plurality of driving grooves 152 are annularly distributed on the outer side of the upper end of the driving disk 151. A driving rod 153 is hinged inside the driving groove 152. The other end of the driving rod 153 is hinged to the inner side of the upper end of the placing plate 14; and the driving disk 151 is located directly above the telescopic device 12; Fixing plates 147 are arranged at the ends of the two sliding plates 143 close to the rotating disk 13. A rubber strip 148 is arranged between the fixing plates 147. The rubber strip 148 is in contact with the outer side of the placing plate 14.

[0019] The specific working process is as follows: When coating the optical lens, first open the hatch on the vacuum coating machine so that the rotating disk 13 and the placing plate 14 inside the machine body 1 are exposed. Subsequently, the staff installs the optical lens to be coated in the placing holes 141 on the placing plate 14. During the installation process, the staff can control the driving motor 11 on the machine body 1 to rotate slowly, so that after installing the optical lens on one placing plate 14, other placing plates 14 can be rotated to a position convenient for installing the optical lens; After all the placing 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 works, 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 contract towards the inside of the rotating disk 13; In the initial state, multiple placement plates 14 are vertically downward, and the telescopic columns 15 are in the state of protruding from 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 the umbrella bone structure in the prior art. Therefore, 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 moves closer to 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 to the outside of the rotating disk 13. During the process, the end of the driving rod 153 hinged to the placement plate 14 will push the placement plate 14, and one end of the placement plate 14 is hinged to the rotating disk 13, so that the placement plate 14 rotates. The placement plate 14 gradually opens from the vertically downward state, and the end of the placement plate 14 away from the rotating disk 13 approaches the inner wall of the machine body 1. The working state of the placement plate 14 is similar to the opening of the umbrella bone of an umbrella. Subsequently, the driving motor 11 works, the driving motor 11 drives the rotating disk 13 to rotate, the telescopic column 15 and the driving disk 151 at the lower end of the rotating disk 13 rotate synchronously, and at the same time, the placement plate 14 and the driving rod 153 rotate synchronously, so as to coat the optical lens at the lower end of the opened placement plate 14; During the opening process of the above-mentioned placement plate 14, since two sliding grooves 142 are opened on the outer side of the placement plate 14, a plurality of placement holes 141 are located between the two sliding grooves 142, and a sliding plate 143 is slidably connected inside the sliding groove 142. A reel 144 is rotatably connected between the two sliding plates 143 through a rotating shaft, and a roll of paper 145 is sleeved on the reel 144. The material of the roll of paper 145 is a silicone sheet, and one end of the roll of paper 145 is fixed to the end of the placement plate 14 away from the rotating disk 13. And the adjacent sliding plates 143 on each placement plate 14 are connected by a steel wire rope 146. When the plurality of placement plates 14 open, the ends of the placement plates 14 away from the rotating disk 13 will move away from each other. At this time, the distance between the plurality of sliding plates 143 at the end of the placement plate 14 away from the rotating disk 13 becomes larger, but the distance between the sliding plates 143 on the plurality of placement plates 14 is connected by the steel wire rope 146 and cannot move away from each other. Therefore, due to the extrusion when the placement plate 14 opens, the sliding plate 143 will slide inside the sliding groove 142 towards the end close to the rotating disk 13. During the process, since one end of the roll of paper 145 is fixed, the reel 144 will rotate to unwind the roll of paper 145, and the reel 144 and the rotating shaft are hinged through a torsion spring, so that the torsion spring between the reel 144 and the rotating shaft is compressed; When the above-mentioned skateboard 143 drives the reel 144 to move on the placement board 14 in the direction close to the rotating disk 13, the roll paper 145 unwinds to cover the placement holes 141 on the placement board 14, and then the roll paper 145 covers the optical lenses inside the placement holes 141. Until the skateboard 143 moves to one end of the chute 142 close to the rotating disk 13, the roll paper 145 completely covers the placement holes 141 on the placement board 14, realizing that after the placement board 14 is opened, the roll paper 145 also synchronously covers one end of the optical lens that does not need to be coated for the time being. And when the skateboard 143 moves in the direction of the rotating disk 13, the fixing plate 147 arranged at one end of the skateboard 143 close to the rotating disk 13 and the rubber strip 148 between the two fixing plates 147 move in the direction of the rotating disk 13 synchronously. During this process, the rubber strip 148 will contact one side of the optical lens that does not need to be coated 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 board 14 is driven by the rotating disk 13 to rotate to coat the optical lens; during the process, the roll paper 145 covers one side of the optical lens that does not need to be coated for the time being; to avoid the splashing of vaporized particles and the possible splashing of tiny droplets or particles onto the surface of the optical lens when the evaporation source heats the material; After the coating is completed, the telescopic device 12 resets, and the telescopic device 12 no longer pushes the driving disk 151 and the telescopic column 15, so that the driving disk 151 and the telescopic column 15 reset. During the process, the end of the placement board 14 far from the rotating disk 13 rotates downward, so that the ends of the placement board 14 far from the rotating disk 13 approach each other; at the same time, the spring inside the chute 142 elastically resets, so that the skateboard 143 slides to the end far 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 winds 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 cover, realizing the improvement of the coating efficiency of the optical lens; It should be noted that the reel 144 and the roll paper 145 are movably installed, and the roll paper 145 is fixed on the placement board 14 by using a pressing plate fixing method. At the same time, the reel 144 can also be disassembled on the rotating shaft between the skateboards 143, so that it is convenient to replace the roll paper 145 before its life is about to end.

[0020] Embodiment 2:

[0021] As Figures 3 to 12As shown in the figure; a support plate 16 is fixed at one end of the placement plate 14 close to the rotating disk 13. The gap between the end of the support plate 16 far from the rotating disk 13 and the placement plate 14 is greater than the height of the sliding plate 143. A clamping claw 161 is hinged to the end of the support plate 16 far from the rotating disk 13 through a torsion spring. The clamping claw 161 is of a U-shaped structure. When the sliding plate 143 moves, the fixing plate 147 and the reel 144 cross the gap between the clamping claw 161 and the placement plate 14, and the fixing plate 147 squeezes the end of the clamping claw close to the placement plate 14; A rubber column 162 is provided at the end of the clamping claw 161 far from the placement plate 14.

[0022] The specific working process is as follows: And when the above-mentioned reel 144 moves towards the end close to the rotating disk 13, a support plate 16 is fixed at one end of the placement plate 14 close to the rotating disk 13, and a clamping claw 161 is hinged to the end of the support plate 16 far from the rotating disk 13 through a torsion spring, so that the clamping claw 161 is of a U-shaped structure. When the sliding plate 143 moves towards the end of the chute 142 close to the rotating disk 13, the fixing plate 147 on the sliding plate 143 moves synchronously. The end of the fixing plate 147 close to the rotating disk 13 will squeeze the end of the clamping claw 161 close to the surface of the placement plate 14. During this process, since the distance between the end of the clamping claw 161 far from the surface of the placement plate 14 and the placement plate 14 is greater than the height of the sliding plate 143, in the initial state, the distance between the end of the clamping claw 161 far from the surface of the placement plate 14 and its surface is greater than the maximum distance between the reel 144 and the placement plate 14. At the same time, when the reel 144 moves to one side of the chute 142 close to the rotating disk 13, the reel 144 is in a state of unwinding, meeting the condition that the reel 144 passes through the gap between the end of the clamping claw 161 far from the surface of the placement plate 14 and the placement plate 14, so that the reel 144 enters between the U-shaped structure of the clamping claw 161. During the process, the fixing plate 147 squeezes the end of the clamping claw 161 close to the placement plate 14, and the clamping claw 161 rotates, so that the end of the clamping claw 161 far from the surface of the placement plate 14 gradually approaches the surface of the placement plate 14 until the end of the clamping claw 161 far from the surface of the placement plate 14 squeezes the roll paper 145 behind the reel 144; after the roll paper 145 covers the optical lens, both ends of the roll paper 145 are limited; to avoid a gap between the end of the roll paper 145 close to the rotating disk 13 and the surface of the placement plate 14 after the roll paper 145 covers the optical lens, resulting in instability of the end of the roll paper 145 close to the rotating disk 13 when the rotating disk 13 rotates; and the extrusion end of the end of the clamping claw 161 far from the surface of the placement plate 14 when squeezing the roll paper 145 is the rubber column 162, avoiding damage to the roll paper 145; Based on the above Embodiment 1, when the placement plate 14 resets, the sliding plate 143 resets synchronously. The fixing plate 147 on the sliding 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. The end of the claw 161 that rotates away from the surface of the placement plate 14 gradually stops squeezing the roll paper 145. At the same time, the reel 144 winds up the roll paper 145 and disengages from between the claws 161 of the U-shaped structure; the reset is achieved.

[0023] Embodiment 3:

[0024] As Figures 2 to 12 shown; cylindrical grooves 17 are opened between adjacent placement holes 141, and cylindrical rods 171 are rotatably connected between each pair of cylindrical grooves 17; a placement ring 172 is rotatably connected inside each placement hole 141, and the outer side of the placement ring 172 is connected to the cylindrical rod 171 inside the cylindrical groove 17. The end of the placement plate 14 away from the turntable 13 is rotatably connected to a ratchet disc 173. The outer side of the ratchet disc 173 is a gear structure, and the middle of the ratchet disc 173 is connected to the cylindrical rod 171 inside the cylindrical groove 17. A gear ring 174 is provided at the upper end inside the machine body 1; when the placement plate 14 rotates, the outer side of the ratchet disc 173 meshes with the gear ring 174.

[0025] The specific working process is as follows: Cylindrical grooves 17 are opened between adjacent placement holes 141, and cylindrical rods 171 are rotatably connected inside each cylindrical groove 17. A placement ring 172 is rotatably connected inside the placement hole 141, such 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 into the placement ring 172; By rotatably connecting a ratchet disc 173 to the end of the placement plate 14 away from the turntable 13, the outer side of the ratchet disc 173 is a gear structure, and the structure of the ratchet disc 173 is the same as the ratchet and pawl structure in the prior art, such that the ratchet disc 173 is divided into an inner disc and an outer disc. The inner disc of the ratchet disc 173 is connected to the cylindrical rod 171, and the outer side of the outer disc of the ratchet disc 173 is a gear structure; On the basis of the above-mentioned first embodiment, after the placement plate 14 is opened, the outer side of the ratchet wheel disc 173 at the end of the placement plate 14 away from the rotating disc 13 is engaged with the gear ring 174 fixed to the upper end inside the machine body 1; during the process of coating the optical lens, the driving motor 11 drives the rotating disc 13 to rotate clockwise. At this time, the rotating disc 13 drives the ratchet wheel disc 173 to move clockwise at the lower end of the gear ring 174. At the same time, the outer disc of the ratchet wheel disc 173 rotates on the outside of the inner disc of the ratchet wheel disc 173. During this process, the inner disc of the ratchet wheel disc 173 and the outer disc of the ratchet wheel disc 173 rotate relative to each other, so that the outer disc of the ratchet wheel disc 173 cannot drive the inner disc of the ratchet wheel disc 173 to rotate; the inner disc of the ratchet wheel disc 173 does not drive the cylindrical rod 171 to rotate, and further the placement ring 172 does not drive the optical lens to rotate, and the optical lens is coated during the process; After one side of the optical lens is coated, the staff controls the driving motor 11 to rotate counterclockwise. At this time, the ratchet wheel disc 173 rotates counterclockwise under the gear ring 174. During this process, the inner disc and the outer disc of the ratchet wheel disc 173 are engaged with each other, so that the outer disc of the gear disc rotates to drive the inner disc to rotate synchronously. During the process, the inner disc of the ratchet wheel disc 173 drives the cylindrical rod 171 to rotate, 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 end of the optical lens rotates to the lower end of the roll paper 145, and the roll paper 145 covers it. The uncoated end of the optical lens rotates to the inside of the placement plate 14; when the placement ring 172 rotates, the outside of the placement ring 172 will squeeze the roll paper 145. During the process, since the roll paper 145 is made of silica gel sheet material and has the characteristic of elastic deformation, and both ends of the roll paper 145 are limited; so when the placement ring 172 rotates, it squeezes the roll paper 145 sheet, and the roll paper 145 sheet deforms. When the rotation of the placement ring 172 stops, the roll paper 145 sheet restores elastically; After the placement ring 172 rotates, stop the counterclockwise rotation of the driving motor 11, and make the driving motor 11 rotate clockwise. At this time, the inner disc of the ratchet wheel disc 173 and the outer disc of the ratchet wheel disc 173 rotate relative to each other, so that the outer disc of the ratchet wheel disc 173 cannot drive the inner disc of the ratchet wheel disc 173 to rotate, thereby realizing that the placement ring 172 cannot rotate, so as to coat the uncoated side of the optical lens; thereby realizing that the two sides of the optical lens can be coated at one time without opening the vacuum coating machine, and during the process, the side that does not participate in the coating can be covered; improving the coating efficiency.

[0026] Embodiment 4:

[0027] As Figures 3 to 12 shown; a disc 121 is fixed to the output end of the telescopic device 12, and a plurality of support members 122 are annularly distributed on the outer side of the disc 121. A cleaning roller 123 is provided on each support member 122, and the cleaning roller 123 is in contact with the inner side of the placement plate 14; A rotating ring 124 is rotatably connected to the central position at the upper end of the disc 121, and the upper end of the rotating ring 124 protrudes above the upper end of the disc 121.

[0028] The specific working process is as follows: By fixing the disc 121 at the output end of the telescopic device 12, the support members 122 are annularly distributed outside the disc 121, and the cleaning rollers 123 are arranged on the support members 122 so that the cleaning rollers 123 are 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 extends inside the machine body 1, the output end of the telescopic device 12 will push the disc 121 upward. During the process, the support members 122 outside the disc 121 move upward synchronously, so that the cleaning rollers 123 move upward synchronously. Since the cleaning rollers 123 are in contact with the inner side of the placement plate 14, when the cleaning rollers 123 move 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 during the coating of the optical lens; and by rotatably connecting the rotating ring 124 to the central position at the upper end of the disc 121, the upper end of the rotating ring 124 protrudes above the upper end of the disc 121; so that when the telescopic device 12 extends, 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; further realizing that 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 rotates relative to the disc 121 at the upper end of the telescopic device 12. 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, realizing a reduction in the frictional force between the disc 121 and the driving disc 151.
