Description

Technical Field

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

[0002] The coating process for optical lenses is generally carried out in a vacuum chamber. The operator first manually embeds the optical lens into the mounting groove of the coating plate, and then emits the coating material through the coating emission source so that the material adheres to the surface of the optical lens to form a thin film, thereby completing the coating of the lens.

[0003] According to a published application for a coating apparatus for optical lens processing (publication number: CN217869055U), the above application includes a vacuum chamber, a sealed door, an evaporation jet assembly, a rotating assembly, and a placement tray. The front left side of the vacuum chamber is equipped with a sealed door that rotates via a hinge. The lower part of the inner side of the vacuum chamber is equipped with an evaporation jet assembly, the upper part of the inner side of the vacuum chamber is equipped with a rotating assembly, and the placement tray is located below the rotating assembly.

[0004] However, in actual use, during the vacuum coating process, the film layer is formed by the deposition of vapor molecules generated by the evaporation jet assembly onto the lens surface. If the lens is placed at an angle, the distance and incident angle between different areas and the evaporation source will be different, resulting in inconsistent vapor molecule deposition rates. Changes in the incident angle will cause different film density, slight differences in refractive index, uneven film thickness distribution, and deviations in optical performance. In view of this, we propose a coating device for optical lens processing. Utility Model Content

[0005] The purpose of this invention is to provide a coating apparatus for optical lens processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a coating device for optical lens processing, comprising a vacuum chamber, an evaporation jet assembly fixedly connected to the bottom surface of the vacuum chamber, an injection port opened at the top of the evaporation jet assembly, a rotating assembly for driving the lens to move inside the vacuum chamber, and a clamping assembly for fixing the lens inside the vacuum chamber.

[0008] Preferably, the lower gear ring meshes with the upper gear ring, the locking block is movably connected with the limiting block, the planetary gear meshes with the sun gear, and when the sun gear rotates, the planetary gear rotates along the sun gear.

[0009] Preferably, the clamping assembly includes a connecting frame fixedly connected to the bottom end of the planetary gear, a rotating rod rotatably connected to the side wall of the connecting frame, and an annular frame fixedly connected to the end face of the rotating rod.

[0010] Preferably, a knob is fixedly connected to one end of the rotating rod outside the connecting frame, and an elastic rod is fixedly connected inside the annular frame. The elastic rod is movably connected to the lens. Rotating the knob drives the annular frame to rotate, causing the lens to flip over and coating both sides of the lens.

[0011] Preferably, the side wall of the rotating rod is provided with a limiting component, the limiting component includes a slot formed in the side wall of the rotating rod, the inner wall of the connecting frame is provided with a spring, and the inner wall of the connecting frame is provided with steel balls.

[0012] Preferably, the slot is movably connected to the steel ball, one end of the spring abuts against the connecting frame, and the other end of the spring is movably connected to the steel ball. The steel ball is stuck in the slot to prevent accidental rotation of the rotating rod and the ring frame.

[0013] Compared with the prior art, the present invention provides a coating device for optical lens processing, which has the following beneficial effects:

[0014] 1. This coating device for optical lens processing, through the combination of rotation and revolution of the lens via a rotating component and a clamping component, ensures that the coating surface of the lens is always in a uniform rotation state, improving coating uniformity and adhesion consistency. The rotation direction of the lens is perpendicular to the lens axis, making the coating thickness distribution more uniform and improving the film density and adhesion quality. Subsequently, the sun gear and planetary gear rotate synchronously, and the planetary gear no longer rotates on its own axis but only revolves with the planetary carrier, keeping the knob on the periphery of the rotating component, which is convenient for the operator to flip or adjust the position, and coating both sides of the lens.

[0015] 2. The coating device for optical lens processing uses a limiting component and a spring to automatically push the steel ball back into the slot, locking the position of the rotating rod and the ring frame. This ensures that the lens will not rotate accidentally during coating or handling. The limiting component can lock the rotating rod and the ring frame when not in operation, reducing the risk of damage or uneven coating and improving operational safety. Attached Figure Description

[0024] like Figures 1-7 As shown, this utility model provides a technical solution: a coating device for optical lens processing, including a vacuum chamber 1, an evaporation jet assembly 2 fixedly connected to the bottom surface of the vacuum chamber 1, an injection port 3 opened on the top of the evaporation jet assembly 2, a rotating assembly 4 for driving the lens to move inside the vacuum chamber 1, and a clamping assembly 5 for fixing the lens inside the vacuum chamber 1.

[0025] In one embodiment of this utility model, the rotating assembly 4 includes an electric push rod 401 fixedly connected to the bottom surface inside the vacuum chamber 1. A lower gear ring 402 is fixedly connected to the output end of the electric push rod 401. A servo motor 403 is fixedly connected to the top end face of the vacuum chamber 1. A rotating shaft 404 is fixedly connected to the output end of the servo motor 403. A locking block 405 is fixedly connected to the side wall of the rotating shaft 404. A sun gear 406 is sleeved on the side wall of the rotating shaft 404. An upper gear ring is fixedly connected to the bottom of the sun gear 406. 407. A limiting block 408 is fixedly connected to the inner wall of the sun gear 406. A planet carrier 409 is fixedly connected to the side wall of the rotating shaft 404. The planet carrier 409 is sleeved with the rotating rod 410. A planet gear 411 is rotatably connected to the side wall of the rotating rod 410. The lower gear ring 402 meshes with the upper gear ring 407. The locking block 405 is movably connected to the limiting block 408. The planet gear 411 meshes with the sun gear 406. When the sun gear 406 rotates, the planet gear 411 rotates along the sun gear 406.

[0026] The clamping assembly 5 includes a connecting frame 501 fixedly connected to the bottom of the planetary gear 411. A rotating rod 502 is rotatably connected to the side wall of the connecting frame 501. An annular frame 503 is fixedly connected to the end face of the rotating rod 502. A knob 504 is fixedly connected to one end of the rotating rod 502 located outside the connecting frame 501. An elastic rod 506 is fixedly connected inside the annular frame 503. The elastic rod 506 is movably connected to the lens. Rotating the knob 504 drives the annular frame 503 to rotate, causing the lens to flip over and coating both sides of the lens.

[0027] The electric push rod 401 drives the lower gear ring 402 to move up and down. When the electric push rod 401 extends upward, the lower gear ring 402 rises and meshes with the upper gear ring 407 fixed at the bottom of the sun gear 406. At this time, the rotation of the sun gear 406 is restricted, keeping the sun gear 406 stationary. Driven by the servo motor 403, the planetary carrier 409 and the rotating rod 410 drive the planetary gear 411 to revolve around the sun gear 406. Since the sun gear 406 is fixed and does not rotate, the planetary gear 411 rotates simultaneously under the meshing action, driving the connecting frame 501 fixed at its bottom and the lens to achieve a compound motion of rotation and revolution. This makes the coating surface of the lens always in a uniform rotation state, improving the coating uniformity and adhesion consistency. The rotation direction of the lens is perpendicular to the axis of the lens, making the coating thickness distribution more uniform and improving the film density and adhesion quality.

[0028] When the electric push rod 401 retracts, the lower gear ring 402 descends and disengages from the upper gear ring 407. After the rotating shaft 404 moves down, the locking block 405 on the side wall of the rotating shaft 404 abuts against the limiting block 408 on the inner wall of the sun gear 406, causing the sun gear 406 to rotate together with the rotating shaft 404. At this time, the sun gear 406 and the planetary gear 411 rotate synchronously. The planetary gear 411 no longer rotates on its own axis, but only revolves with the planet carrier 409, so that the knob 504 is kept on the periphery of the rotating component 4, making it convenient for the operator to flip or adjust the position.

[0029] In addition, a limiting component 6 is provided on the side wall of the rotating rod 502. The limiting component 6 includes a slot 603 formed on the side wall of the rotating rod 502, a spring 601 and a steel ball 602 provided on the inner wall of the connecting frame 501. The slot 603 is movably connected to the steel ball 602. One end of the spring 601 abuts against the connecting frame 501, and the other end of the spring 601 is movably connected to the steel ball 602. During operation, when the knob 504 applies torque, the steel ball 602 disengages from the slot 603, allowing the rotating rod 502 to drive the ring frame 503 to rotate, thereby flipping the lens. After the operation is completed, the spring 601 automatically pushes the steel ball 602 back into the slot 603, locking the position of the rotating rod 502 and the ring frame 503, ensuring that the lens will not rotate accidentally during coating or handling. The limiting component 6 can lock the rotating rod 502 and the ring frame 503 when not in operation, reducing the risk of damage or uneven coating and improving operational safety.

[0030] In this invention, during use, the electric push rod 401 drives the lower gear ring 402 to move up and down to control the state of the sun gear 406. When the electric push rod 401 rises, the lower gear ring 402 meshes with the upper gear ring 407, restricting the rotation of the sun gear 406, so that the planetary gear 411 rotates on its own axis while revolving around the sun, driving the lens to rotate in a direction perpendicular to its axis, achieving uniform coating, improving the uniformity, density and adhesion quality of the film thickness distribution. When the electric push rod 401 falls, the lower gear ring 402 disengages from the upper gear ring 407, the locking block 405 cooperates with the limiting block 408, the sun gear 406 rotates with the rotating shaft 404, and the planetary gear 411 only revolves around the sun, so that the knob 504 is kept on the periphery of the rotating component 4, making it easy for the operator to flip or adjust the position.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
