Description

Technical Field

[0001] This utility model relates to the field of lens coating technology, specifically a coating device for optical lens production. Background Technology

[0002] Lenses are transparent materials with one or more curved surfaces, made of optical materials such as glass or resin. After processing such as coating, they are often assembled into eyeglasses with eyeglass frames. In the current coating process, most lenses need to be fixed and limited to ensure the effectiveness of the coating process.

[0003] An investigation revealed that a Chinese utility model patent discloses a coating device for optical lens production (publication number: CN221681189U), which includes a fixed frame. The top of the fixed frame is provided with a protective layer. The protective layer is provided with a mounting pad for mounting lenses. The mounting pad is provided with an adsorption element. The adsorption element includes a plurality of adsorption holes spaced apart in the mounting pad. The bottom of the adsorption holes is provided with an air pump for drawing air from the adsorption holes to generate low pressure.

[0004] While the aforementioned patent achieves the purpose of adsorbing and fixing the placed lens by operating the air pump inside the adsorption component, preventing the lens from shifting during the coating process and causing unexpected situations, the coating process requires coating both the top and bottom surfaces of the lens. After coating one side of the lens, the device requires the operator to manually flip the lens, which easily leaves fingerprints on the lens and affects the coating quality. If the lens is clamped and flipped using the clamping component, it still needs to be re-fixed, making the operation too cumbersome.

[0005] Therefore, this invention provides a coating apparatus for optical lens production to solve the above-mentioned problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a coating device, such as Figures 1-6As shown, the technical solution includes a workbench 1 and a mounting shell 2. Mounting plates 3 are symmetrically fixed on the workbench 1. A fixing plate 5 is connected to one side of the mounting plate 3. An electric telescopic rod 6 is fixedly connected to the end of the fixing plate 5. An electric suction cup 7 is fixedly connected to the output end of the electric telescopic rod 6. A flipping mechanism is provided between the electric suction cup 7 and the mounting plate 3. The flipping mechanism includes a gear 14 and a gear ring 15. The gear 14 and gear ring 15 mesh. By setting the flipping mechanism, the electric suction cup 7, which holds the lens, is flipped. With the cooperation of 7, the lens can be flipped to achieve the effect of coating the upper and lower surfaces of the lens; a positioning mechanism is provided on one side of the mounting plate 3, which includes a chuck 9 and a locking block 17. The chuck 9 is rotatably connected to the side wall of the mounting plate 3, and the chuck 9 is coaxially fixed with the gear 14. Multiple locking slots 16 are provided on the chuck 9, and the locking block 17 is inserted into the locking slots 16. The positioning mechanism can position the electric suction cup 7 at any position, avoiding the electric suction cup 7 from shifting due to unstable center of gravity, which would affect the coating quality of the lens.

[0027] The mounting plate 3 has a cavity, in which gear 14 and gear ring 15 are rotatably connected. An arc groove 4 is provided on one side of the cavity, and a cylindrical block is fixedly and movably connected in the arc groove 4. The two ends of the cylindrical block are fixedly connected to the fixing plate 5 and gear ring 15 respectively. A motor 8 is fixedly connected to the side wall of the mounting plate 3, and the output end of the motor 8 is coaxially fixed with the chuck 9.

[0028] When in use, the motor 8 drives the chuck 9 and gear 14 to rotate. The rotating gear 14 drives the meshing gear ring 15 to rotate. The gear ring 15 drives another electric suction cup 7 to move above the lens through the fixing plate 5. At this time, the electric telescopic rod 6 drives the electric suction cup 7 to adhere to the upper surface of the lens and release the adsorption effect of the electric suction cup 7 below the lens. The flipping mechanism drives the electric suction cup 7 that has been released from adsorption to move away. Finally, the electric suction cup 7 with the lens adsorbed is rotated 180° to make the lower surface of the lens face up, which is convenient for coating.

[0029] It should be noted that the motor 8 is connected to an external power source via wires. The external power source includes a battery for providing power to the motor 8 and a control switch for controlling its start and stop. The external power source is existing technology. The specific model and specifications of the motor 8 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts existing technology in this field, so it will not be described in detail.

[0030] A connecting plate 10 is fixedly connected to the side wall of the mounting plate 3. The connecting plate 10 has a mounting groove, and the locking block 17 is slidably connected in the mounting groove. A baffle 20 is fixedly connected in the mounting groove. A round rod 18 is fixedly connected to the locking block 17, and the round rod 18 slides through the baffle 20. A spring 19 is sleeved on the round rod 18. The two ends of the spring 19 are fixedly connected to the locking block 17 and the baffle 20, respectively. An iron sheet 21 and an electromagnet 22 are provided in the mounting groove, and the iron sheet 21 is fixedly connected to the round rod 18.

[0031] When the starting motor 8 drives the flipping mechanism, it energizes the electromagnet 22, which attracts the iron piece 21. The iron piece 21, through the round rod 18, drives the locking block 17 to compress the spring 19 and retract into the mounting groove, preventing the locking block 17 from restricting the rotation of the chuck 9. When the motor 8 is turned off, the electromagnet 22 is de-energized. At this time, the compressed spring 19 resets and pushes the locking block 17 out of the mounting groove and into the locking slot 16 on the chuck 9, limiting the chuck 9 and preventing the electric suction cup 7, which rotates at a certain angle, from shifting due to instability of the center of gravity.

[0032] The top of the mounting shell 2 is provided with a connecting pipe 13, and the end of the connecting pipe 13 is movably connected to a vacuum pipe 11. The vacuum pipe 11 is rotatably connected to the mounting shell 2 through a bearing 12 so as to prevent the vacuum pipe 11 from obstructing the movement of the fixing plate 5.

[0033] In summary: During operation, the lens is placed on the electric suction cup 7, and the upper surface of the lens is coated. Then, the motor 8 is started to drive the chuck 9 to rotate, and at the same time, the electromagnet 22 is energized. The energized electromagnet 22 attracts the iron piece 21. The iron piece 21 drives the locking block 17 to compress the spring 19 through the round rod 18 and retracts into the mounting groove. The rotating chuck 9 drives the gear 14 to rotate, and the rotating gear 14 drives the meshing gear ring 15 to rotate. The gear ring 15 drives another electric suction cup 7 to move above the lens through the fixing plate 5. At this time, the electric telescopic rod 6 drives this electric suction cup 7 to attract and fix the upper surface of the lens, and releases the attraction effect of the electric suction cup 7 below the lens. The flipping mechanism is driven to remove the electric suction cup 7 that has been released from attraction. Finally, the electric suction cup 7 with the lens is rotated 180° to make the lower surface of the lens face up, which is convenient for coating.

[0034] When the motor 8 is turned off, the electromagnet 22 is de-energized. At this time, the compressed spring 19 resets and pushes the locking block 17 out of the mounting slot and into the locking slot 16 on the chuck 9, limiting the chuck 9 and preventing the electric suction cup 7 from shifting due to instability of the center of gravity when rotating at a certain angle.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
