As a key component of the camera imaging system, the quality of the camera lens directly affects the imaging effect of the camera. By coating the lens surface with one or more layers of special films, the reflection of light can be effectively reduced, the transmittance of the lens can be increased, and the amount of light entering the camera can be increased, thereby improving the brightness and contrast of the image. Coating devices are usually used for coating.

Compared with the traditional coating treatment method on the resin lens by ionizing and bombarding the coating liquid, this method has lower cost and the instruments required are relatively simple, which can effectively reduce the cost of the method. At the same time, the coating is carried out by diffusing the coating liquid by centrifugal force, which can effectively ensure the uniformity of the distribution of the coating liquid on the surface of the resin lens, and ensure the coating effect under the premise of reducing the coating cost.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0038] One of the purposes of the present invention is to provide a coating device for mobile phone camera lenses, see Figure 1-Figure 8As shown, the vacuum machine 100 includes a base 101 inside the vacuum machine 100, a workbench 102 is arranged above the base 101, a coating assembly 300 is arranged below the workbench 102, the coating assembly 300 is used to place lenses for coating, a heating device is arranged inside the vacuum machine 100, the heating device is used to adjust and control the internal temperature of the vacuum machine 100, and is located above the coating assembly 300. An I-shaped rail 103 is arranged above the coating assembly 300, and a cylinder 2 is arranged between the I-shaped rail 103 and the workbench 102. 01. The piston rod at the end of the cylinder 201 is provided with a plastic plate 200. The cylinder 201 drives the plastic plate 200 to move in the vertical direction. The surface of the I-shaped rail 103 is provided with a friction component 400. The friction component 400 is symmetrical. The friction component 400 moves on the surface of the plastic plate 200 and rubs, so that static electricity is generated on the surface of the plastic plate 200 to adsorb dust particles. A dust collection component 500 is provided around the outside of the coating component 300. The dust collection component 500 is used to clean and collect dust adsorbed on the surface of the plastic plate 200:

[0039] During specific use, the coating liquid is dripped into the center of the lens placed inside the placement tray 304, so that the coating liquid is diffused on the surface of the lens, and the coating liquid evenly attached to the surface of the lens is cooled and formed. In order to improve the coating efficiency of the coating liquid, the coating assembly 300 includes a servo motor 301 arranged on the surface of the base 101, and a gear disk 302 is provided at the output end of the servo motor 301. A limiting arc groove is provided at the bottom of the gear disk 302, and a limiting rod 305 is provided on the top of the vacuum body 100. The limiting rod 305 is arranged in a ring array and supports the limiting arc groove of the gear disk 302. Meshing gears 303 are provided at the quadrants of the gear disk 302, and a placement tray 304 is provided on the top of the meshing gear 303. The placement tray 304 is used to place the camera lens. 304 rotates coaxially with the meshing gear 303, and the internal temperature of the vacuum body 100 is adjusted and controlled by the heating device to adjust the temperature to a suitable temperature. When the lens is placed in the placement tray 304 and the coating liquid is dripped into it, the output end of the servo motor 301 is controlled to drive the gear plate 302 to rotate, and the limit rod 305 supports the weight of the gear plate 302, so that the gear plate 302 is stable during the rotation process. When the gear plate 302 rotates, the meshing gear 303 is meshed and rotated, so that the placement tray 304 provided on the top of the meshing gear 303 rotates coaxially. When the placement tray 304 rotates, the coating liquid dripped on the surface of the lens is subjected to the centrifugal force and quickly diffuses outward along the center of the lens, thereby improving the coating efficiency and ensuring the uniformity of the coating.

[0040] During the process of placing the lens inside the vacuum body 100, external dust is easy to enter the vacuum body 100. During the coating process, the floating dust and impurities are easy to fall into the coating solution, causing contamination of the coating solution. Therefore, the friction assembly 400 includes a moving frame 402 arranged on the surface of the I-shaped rail 103, and a rotating motor 401 is arranged on the side wall of the moving frame 402. The output end of the rotating motor 401 drives the friction wheel to drive the moving frame 402 to rotate on the side wall of the I-shaped rail 103. A brush 403 is arranged at the bottom of the moving frame 402, and the moving frame 402 drives the brush 403 to rotate. When the moving frame 402 is in motion, the surface of the plastic plate 200 is rubbed, so that the surface of the plastic plate 200 generates static electricity to absorb dust and impurities. During the coating process, the friction wheel is driven by the output end of the rotating motor 401 to drive the moving frame 402 to move and rotate on the side wall of the I-shaped rail 103. During the rotation process, the brush 403 provided at the bottom of the moving frame 402 rubs against the surface of the plastic plate 200, so that the surface of the plastic plate 200 is negatively charged and generates static electricity to absorb dust and impurities floating above the placement tray 304, thereby preventing dust and impurities from falling into the coating solution and contaminating the lens, thereby improving the coating yield.

[0041] Since the plastic plate 200 has a large area, in order to increase the friction area of ​​the plastic plate 200, increase the adsorption area, and improve the adsorption efficiency of impurities and dust during the movement of the brush 403, a slide groove is provided at the bottom of the moving frame 402, and a moving block 405 is provided in the slide groove for sliding. The brush 403 is fixed at the bottom of the moving block 405, and the moving block 405 slides on the inner wall of the column 404. One end of the column 404 is fixed to one side of the moving frame 402. An elastic member 406 is provided between the column 404 and the moving block 405, and the moving block 405 is pressed to drive the brush 403 along the water surface. The moving block 405 moves in a horizontal direction on the surface of the plastic plate 200. A rotating gear rod 407 is provided on one side of the moving block 405. An eccentric wheel 409 is provided at the end of the rotating gear rod 407. The center of the eccentric wheel 409 is in a through groove shape. A driven gear 410 is provided at the through groove of the eccentric wheel 409. The rotating gear rod 407 drives the driven gear 410 to mesh and rotate. The driven gear 410 drives the eccentric wheel 409 to rotate coaxially. The end of the eccentric wheel 409 is in contact with one side of the moving block 405. A transmission shaft 408 is provided at the end of the rotating gear rod 407 away from the eccentric wheel 409. The transmission shaft 408 and the rotating motor 4 01 are connected by a belt transmission. When the output end of the rotating motor 401 drives the friction wheel to rotate and drive the moving frame 402 to rotate, the transmission shaft 408 at the end of the rotating gear rod 407 is connected to the rotating motor 401 through a belt. When the transmission shaft 408 drives the rotating gear rod 407 to rotate, the driven gear 410 meshed with the end of the rotating gear rod 407 rotates. When the driven gear 410 rotates, it drives the eccentric wheel 409 to rotate coaxially. During the rotation process, the eccentric wheel 409 pushes the end of the moving block 405, so that the moving block 405 compresses the elastic member 406 to move in the column. 404 inner wall, thereby driving the brush 403 to move horizontally away from the eccentric wheel 409. At the same time, when the eccentric wheel 409 stops applying pressure to the moving block 405, the pressure on the elastic member 406 disappears, pushing the moving block 405 to drive the brush 403 to move in the opposite direction, so that the moving block 405 drives the brush 403 to reciprocate horizontally on the surface of the plastic plate 200, rubbing the surface of the plastic plate 200 in an all-round manner, thereby increasing the friction area of ​​the plastic plate 200, increasing the adsorption area, and improving the adsorption efficiency of impurities and dust.

[0042] After the coating is completed, in order to facilitate the cleaning of dust and impurities attached to the surface of the plastic plate 200 and to facilitate the subsequent coating operation, the dust collection component 500 includes a dust collector 501 arranged on the surface of the workbench 102. The dust collectors 501 are arranged in an array outside the coating component 300. A rotating suction cup 502 is provided at the end of the dust collector 501. The rotating suction cup 502 is used to collect dust and impurities adsorbed on the surface of the plastic plate 200. A metal rod 503 is provided under the plastic plate 200. One end of the metal rod 503 is connected to the ground. After the coating is completed, the cylinder 20 1 drives the plastic plate 200 to move to fit with the top of the metal rod 503. After the lens coating is completed, the piston rod at the end of the cylinder 201 drives the plastic plate 200 to move downward in the vertical direction, and the bottom of the plastic plate 200 moves to the metal rod 503. The electric charge on the surface of the plastic plate 200 is introduced to the ground through the metal rod 503 to reduce the adsorption force of the plastic plate 200 on dust and impurities. The rotating suction cup 502 at the end of the vacuum cleaner 501 absorbs and collects the dust and impurities on the surface of the plastic plate 200 to avoid secondary pollution caused by dust and improve the cleanliness of the inside of the vacuum body 100.

[0043] When in use, the temperature inside the vacuum body 100 is adjusted by the heating device, the lens is placed on the surface of the placement plate 304 and the coating liquid is dripped into the center of the lens, the output end of the servo motor 301 is controlled to drive the gear plate 302 to rotate, and the limit rod 305 supports the weight of the gear plate 302, so that the gear plate 302 is stable during the rotation process, and the gear plate 302 drives the meshing gear 303 to mesh and rotate when rotating, so that the placement plate 304 provided on the top of the meshing gear 303 rotates coaxially, and when the placement plate 304 rotates, the coating liquid dripped on the surface of the lens is subjected to the centrifugal force, and quickly spreads outward along the center of the lens, thereby improving the coating efficiency;

[0044] The transmission shaft 408 at the end of the rotating gear rod 407 is connected to the rotating motor 401 through a belt. When the transmission shaft 408 drives the rotating gear rod 407 to rotate, the driven gear 410 meshed with the end of the rotating gear rod 407 rotates. When the driven gear 410 rotates, it drives the eccentric wheel 409 to rotate coaxially. During the rotation process, the eccentric wheel 409 pushes the end of the moving block 405, so that the moving block 405 compresses the elastic member 406 and moves on the inner wall of the column 404, so that the moving block 405 drives the brush 403 to reciprocate in the horizontal direction on the surface of the plastic plate 200, and rubs the surface of the plastic plate 200 comprehensively. , thereby increasing the friction area of ​​the plastic plate 200, increasing the adsorption area, and improving the adsorption efficiency of impurities and dust. After the lens coating is completed, the piston rod at the end of the cylinder 201 drives the plastic plate 200 to move downward in the vertical direction, and the bottom of the plastic plate 200 moves to the metal rod 503. The charge on the surface of the plastic plate 200 is introduced to the ground through the metal rod 503, reducing the adsorption force of the plastic plate 200 on dust and impurities. The rotating suction cup 502 at the end of the vacuum cleaner 501 absorbs and collects dust and impurities on the surface of the plastic plate 200 to avoid secondary pollution caused by dust and improve the cleanliness of the inside of the vacuum body 100.
