DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1

[0032] Reference Figure 1-6 , an optical coated lens coating processing system, used for processing optical lenses of different sizes and specifications that need double-sided coating, including a processing chamber 1, a suspension component 2 and a flip matching component 3, the processing chamber 1 is divided into a coating chamber 101, a drying chamber 102 and a washing chamber 103, the suspension component 2 can move horizontally on the top of the processing chamber 1 and move from the washing chamber 103 to the coating chamber 101 via the drying chamber 102, the optical lens fixed by the suspension component 2 can be turned over by the matching component 3 after one side is coated in the coating chamber 101, and then fixed again by the suspension component 2 to coat the other side.

[0033] An ultrasonic washing tank 11 is installed at the bottom of the washing chamber 103, and a self-cleaning tank 12 is arranged on the periphery of the ultrasonic washing tank 11. The self-cleaning tank 12 is connected to the ultrasonic washing tank 11 through a reflux pump 13. Before coating, the suspension component 2 moves to the top of the ultrasonic washing tank 11 and inserts the receiving part 21 into the bottom of the ultrasonic washing tank 11. Then, the optical lens to be coated on the outside is put into the ultrasonic washing tank 11 and received by the receiving part 21. The lens is ultrasonically cleaned in the ultrasonic washing tank 11, and then lifted up by the suspension component 2 to be separated from the ultrasonic washing tank 11, and moved to the drying chamber 102 with the suspension component 2 for drying. The washing liquid used to clean the lens is transported to the self-cleaning tank 12 by the reflux pump 13 for purification and cleaning, and flows back to the ultrasonic washing tank 11 after purification for the next lens cleaning.

[0034] The first fan 14 is installed on the top of the drying chamber 102, and the first fan 14 can circulate clean hot air into the drying chamber 102 to remove the residual moisture on the surface of the optical lens therein. A lifting barrier door 4 is installed between the coating chamber 101 and the drying chamber 102, and between the drying chamber 102 and the washing chamber 103. When the lenses are washed and dried, the lifting barrier door 4 between the coating chamber 101 and the drying chamber 102 rises to isolate the coating chamber 101 from the drying chamber 102, so that the second fan 14 installed on the top of the coating chamber 101 can be removed. The machine 5 can evacuate the coating chamber 101 during the lens washing and drying operations. After the suspension component 2 moves to the drying chamber 102, the lifting barrier door 4 between the drying chamber 102 and the washing chamber 103 rises to isolate the drying chamber 102 from the washing chamber 103, so that the hot air flow circulates only in the drying chamber 102 to dry the lenses more efficiently. After the lenses are dried, the lifting barrier door 4 between the coating chamber 101 and the drying chamber 102 descends to connect the coating chamber 101 with the drying chamber 102, so as to allow the suspension component 2 to move into the coating chamber 101.

[0035] An evaporation source 6 is installed at the bottom of the coating chamber 101. After the suspension assembly 2 is moved into the coating chamber 101, it is moved to directly above the evaporation source 6, and the receiving portion 21 is turned over so that the side of the lens facing the evaporation source 6 is successfully coated.

[0036] Example 2

[0037] Reference Figure 1-6, a coating processing system for optically coated lenses, the difference between this embodiment and embodiment 1 is that the suspension assembly 2 includes a receiving part 21, a hanging frame 22, a closing cover 23, a middle control 24 and a moving part 25, the receiving part 21 and the closing cover 23 are installed between the vertical frames symmetrically arranged on both sides of the hanging frame 22, the middle control 24 is installed on the upper part of the hanging frame 22, the moving part 25 is installed on the upper part of the middle control 24, the top plate of the processing chamber 1 is provided with a plurality of hanging ports 104 in a horizontal array, and the moving part 25 cooperates with the hanging ports 104 to drive the entire suspension assembly 2 to move horizontally on the top of the processing chamber 1.

[0038] The receiving portion 21 includes a closed cylinder 211, a plurality of rotating screws 212 densely arranged in the closed cylinder 211, and a clamping column 213 corresponding to the rotating screw 212. A threaded cavity 201 is arranged at the center of the inner axis of the clamping column 213. The end of the rotating screw 212 is arranged in the threaded cavity 201 and cooperates with the thread of the inner wall of the threaded cavity 201. A plurality of limiting plug rods 214 corresponding to the clamping column 213 are fixedly arranged on the top wall of the closed cylinder 211. The limiting plug rods 214 are vertically inserted into the clamping column 213 to prevent the clamping column 213 from axially rotating, so that the rotating screw 212 is driven to rotate by the top motor. When the clamping column 213 is driven to move vertically, there is a gap between each of the clamping columns 213. An expansion chamber 202 is arranged on the outer peripheral side of one end of the clamping column 213 away from the top wall of the closing cylinder 211. The expansion chamber 202 is filled with a small amount of gas and has an initial air pressure. The outer periphery of the expansion chamber 202 is made of a ductile material, such as silicone. The air pressure in the expansion chamber 202 is lower than normal pressure. Therefore, under normal pressure, the expansion chamber 202 is deflated into the peripheral wall of the clamping column 213. When entering a vacuum environment, the expansion chamber 202 will be propped up to make the peripheral wall of the expansion chamber 202 bulge out of the peripheral wall of the clamping column 213, thereby filling the gap between the clamping columns 213.

[0039] The closed cylinder 211 has rotating shafts inserted into the hanging frame 22 on both sides, and a vertical guide rail extending vertically is arranged in the hanging frame 22. The rotating shaft is connected to a vertical movement motor arranged in the vertical guide rail. The vertical movement motor can move vertically up and down along the vertical guide rail and drive the closed cylinder 211 connected to the rotating shaft to flip. When the washing operation is performed, the closed cylinder 211 is placed in the ultrasonic washing tank 11 with the clamping column 213 facing upward, and the optical lens will be placed on the top of each clamping column 213. After the lens is washed, the closed cylinder 211 moves the lens to the drying chamber 102 for drying, and the threaded cavity 201 is away from the top of the closed cylinder 211. A pressure sensor 215 is provided at one end of the wall. After the lens is dried, all the clamping columns 213 of the pressure sensors 215 that feel the gravity of the lens will move down compared with other clamping columns 213 until the periphery of the lens corresponds to the vertical position of the expansion chamber 202. Then, the connection between the coating chamber 101 and the drying chamber 102 is opened to make the drying chamber 102 in a vacuum state. The periphery of the expansion chamber 202 expands and firmly clamps the peripheral wall of the lens. After the closed cylinder 211 is moved into the coating chamber 101 and turned over, the lens can be coated. The middle control 24 can drive the axial rotation of the hanging frame 22 connected to the washing during the coating process, so that the lens coating is more uniform.

[0040] The closing cover 23 is arranged between the receiving part 21 and the central control unit 24, and can be moved vertically up and down along the vertical guide rail through a structure similar to or the same as the receiving part 21. After the coating of one side of the lens is completed, the receiving part 21 is flipped so that the coated surface of the lens faces the closing cover 23. Then the receiving part 21 and the closing cover 23 move toward each other so that the closing cylinder 211 is connected to the closing cover 23, so that each clamping column 213 and the lens are sealed in the back pressure cavity formed by the buckling of the closing cylinder 211 and the closing cover 23. The plate surface of the closing cover 23 facing the central control unit 24 is provided with a connecting port 203.

[0041] The middle control 24 has a ventilation head 241 on the side facing the closing cover 23, and an air receiving head 242 on the top of the middle control 24. The top plate of the processing chamber 1 has an air receiving window 105 connected to the second fan 5. When the receiving part 21 moves to the top of the evaporation source 6, the air receiving head 242 is just below the air receiving window 105. After the closing cylinder 211 is docked with the closing cover 23, the air receiving head 242 extends toward the air receiving window 105 and docks with the second fan 5. 211 and the closing cover 23 move up together to make the connecting port 203 dock with the ventilation head 241. At this time, the second fan 5 can inject air into the back-pressure chamber formed by the closing cylinder 211 and the closing cover 23 through the air connecting head 242 and the ventilation head 241 to restore the air pressure in the back-pressure chamber. At this time, the expansion chamber 202 shrinks and separates from the lens to release the fixation of the lens by the clamping column 213. After that, all the clamping columns 213 are adjusted to be flush with the top end so that the lens is in a state of being lifted up by the clamping column 213.

[0042] After the clamping column 213 returns to the state of lifting the lens, the second fan 5 evacuates the back pressure chamber again, and the closing cylinder 211 is separated from the closing cover 23 up and down. The expansion chamber 202 is at a certain distance from the end of the clamping column 213 to allow the expansion chamber 202 to be in an inflated state, and the lower part of the lens still has space to allow the flip-fitting assembly 3 to be placed.

[0043] The movable member 25 includes a track drive unit 251, a rotating track 252 and a suspension block 253. The track drive unit 251 is fixedly installed on the top of the central control unit 24. The motor of the track drive unit 251 can drive a number of track drive rollers 254 to rotate axially. The rotating track 252 cooperates with the track drive roller 254 teeth and is driven to rotate by the rotating track drive roller 254. The suspension block 253 is evenly arranged on the surface of the rotating track 252 and can be accurately placed in the lifting port 104 during the rotation of the rotating track 252. The suspension block 253 in a special position will not fall off from the lifting port 104 after being placed in the lifting port 104, thereby keeping the suspension assembly 2 on the top of the processing chamber 1 and making the suspension assembly 2 move horizontally with the rotation of the rotating track 252.

[0044] The suspension block 253 has a pair of transverse displacement cavities 204 extending to the outside of the suspension block 253, and the extension direction of the transverse displacement cavity 204 is the same as the extension direction of the central axis of the crawler drive roller 254. The transverse displacement cavity 204 is provided with a limit displacement block 255 with a tip facing outward. The transverse displacement cavity 204 is also provided with a spring that can push the inclined portion of the limit displacement block 255 out of the transverse displacement cavity 204 under normal conditions. The side wall of the lifting port 104 has a limiting groove 106 that allows the inclined portion of the limit displacement block 255 to extend into. When the suspension block 253 is placed in or moved out of the lifting port 104, the edge of the lifting port 104 can push the inclined surface of the limit displacement block 255 to make the limit displacement block 255 overcome the spring force and retract into the transverse displacement cavity 204, and pop out again after the suspension block 253 is placed in or moved out of the lifting port 104.

[0045] The transverse movement cavity 204 is provided with a magnetic resistance block 256, and the magnetic resistance block 256 can move closer to or away from the rotary track 252 under the influence of the spring. The magnetic resistance block 256 is located in the side wall of the transverse movement cavity 204 when the spring is at a normal length. At this time, the magnetic resistance block 256 avoids the moving path of the limit displacement block 255 so that the limit displacement block 255 can smoothly move into the transverse movement cavity 204. A plurality of permanent magnet blocks 257 are also provided between the track drive parts 251, and in addition to the track drive rollers 254 provided at both ends of the track drive part 251, the track drive rollers 254 are all magnetic, and when the suspension block 253 moves to the permanent magnet block 257 and the track drive roller 254 having magnetic force, the suspension block 253 moves to the permanent magnet block 257 and the track drive roller 254 having magnetic force. 54 is in the magnetic influence area, the magnetic attraction resistance block 256 will be attracted and explore the moving path of the limit displacement block 255, thereby preventing the limit displacement block 255 from moving into the transverse movement cavity 204, and the limit displacement block 255 that remains extended out of the transverse movement cavity 204 will make the suspension block 253 unable to move out of the lifting port 104, and then make the suspension assembly 2 unable to separate from the top wall of the processing chamber 1. When the suspension block 253 moves to the two ends of the track drive part 251 with the rotating crawler 252 and tends to separate from or be placed in the lifting port 104, the magnetic attraction resistance block 256 is in the magnetic non-affected area and is pulled back by the spring to avoid the moving path of the limit displacement block 255 again, so that the suspension block 253 can smoothly separate from or be placed in the lifting port 104.

[0046] It can be understood that since the movable member 25 is suspended on the top wall of the processing chamber 1 and moves through the cooperation of the suspension block 253 and the lifting port 104, the array-arranged lifting ports 104 will not be interconnected like tracks, and the door panel of the lifting barrier door 4 can be completely attached to the top wall of the processing chamber 1 after moving up, thereby completely blocking the coating chamber 101, the drying chamber 102 and the washing chamber 103 from each other, ensuring the sealing between the coating chamber 101, the drying chamber 102 and the washing chamber 103 after the lifting barrier door 4 is raised and closed.

[0047] Example 3

[0048] Reference Figure 1-6 , a coating processing system for optically coated lenses, the difference between this embodiment and embodiment 2 is that the flip matching assembly 3 includes a vertical guide frame 31, a rotating head 32 and a plurality of clamping members 33, the vertical guide frame 31 is fixedly installed on the side wall of the processing chamber 1, the rotating head 32 is installed on the vertical guide frame 31 and can move vertically along the vertical guide frame 31, the clamping members 33 are divided into two groups and installed in a mounting box 34 connected to the rotating head 32 and rotating with the rotating head 32, one group of the clamping members 33 can move close to or away from the other group of the clamping members 33.

[0049] The gaps between the clamping columns 213 form a vertically staggered mesh channel in the closed tube 211. The clamping member 33 includes a hydraulic pipe 331, a telescopic strip 332 and a liquid return tank 333. The hydraulic pipe 331 is installed in the installation box 34. The telescopic strip 332 is installed in the hydraulic pipe 331 and can extend from the hydraulic pipe 331 to the suspension component 2 outside the installation box 34. There is hydraulic fluid in the hydraulic pipe 331 and the liquid return tank 333. The telescopic strip 332 is connected to a hydraulic plug 334 that moves with the volume change of the hydraulic fluid in the hydraulic pipe 331 and can move into or out of the hydraulic pipe 331. The hydraulic pipe 331 and the liquid return tank 333 are connected by a delivery pump 35. The delivery pump 35 can transfer the hydraulic fluid between the hydraulic pipe 331 and the liquid return tank 333.

[0050] After the optical lens is held at the upper end of the clamping column 213 with the coated surface facing upward, the telescopic strips 332 of the two groups of the clamping members 33 will extend from the hydraulic pipe 331, and the telescopic strips 332 at the lower part will be inserted into the transverse channel formed by the gap between the clamping columns 213, and the telescopic strips 332 at the upper part will be suspended above the lens. After each lens has a telescopic strip 332 at the bottom that can support it, the rotating head 32 lifts the mounting box 34 so that the clamping member 33 can lift the lens and detach it from the clamping column 213. After that, the receiving portion 21 and the closing cover 23 are separated from each other to provide space for the clamping member 33 to flip over.

[0051] When the lens is lifted up, the telescopic strip 332 below the lens has an electromagnetic block 335, and the telescopic strip 332 above the lens has an enclosure plate 336. The enclosure plate 336 can be attracted by magnetic force and suspended on the telescopic strip 332 by a spring. The positions and shapes of the enclosure plates 336 installed on each telescopic strip 332 are different, but each enclosure plate 336 can form a circular circle sufficient to surround all the lenses, so that the lower end of each enclosure plate 336 can be closely attached to the telescopic strip 332 below the lens to ensure that the lens will not be thrown out from between the upper and lower sets of telescopic strips 332 when flipped.

[0052] Preferably, the hydraulic plug 334 connected to the telescopic strip 332 provided on the electromagnetic block 335 has an electric contact 337. After the telescopic strip 332 is fully extended out of the hydraulic tube 331, the electric contact 337 contacts the mating contact at the end of the hydraulic tube 331 to transmit external electric energy to the electromagnetic block 335, so that the electromagnetic block 335 generates a magnet to attract the enclosure plate 336 downward, thereby sucking the enclosure plate 336 down until it is close to the telescopic strip 332 at the bottom of the lens. After that, the rotating head 32 quickly flips the mounting box 34 180 degrees so that the coated surface of the lens faces downward.

[0053] It is understandable that in order to ensure that the telescopic strip 332 can smoothly retract the hydraulic pipe 331, the enclosure plate 336 can only be set within the width range provided by the telescopic strip 332, so that adjacent enclosure plates 336 have gaps. Although there are gaps between the enclosure plates 336 forming a circular ring, the lenses still cannot be thrown out from the gaps between the enclosure plates 336 due to the dense arrangement of the telescopic strips 332.

[0054] After the flipping mating assembly 3 flips the lens, the telescopic strip 332 moves into the gap between the clamping columns 213 again and places the lens on the upper end of the clamping columns 213. At this time, the coated surface of the lens faces downward and the uncoated surface faces upward. Then, the receiving part 21 and the closing cover 23 are combined again to restore the air pressure in the back pressure chamber to normal pressure and shrink the expansion chamber 202. Finally, except for the clamping column 213 where the lens is placed, the other clamping columns 213 rise to make the expansion chamber 202 flush with the lens.
