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 equipment for optical lens processing is the core equipment in the manufacturing process of optical lenses. Its main function is to coat the surface of the lens with one or more specific thin films to change the optical properties of the lens, such as increasing the light transmittance, reducing reflection, and resisting ultraviolet rays. In actual production, different types of coating materials are required when multiple coatings are needed for optical lenses.

[0003] A coating apparatus for producing high-quality optical lenses, disclosed in Chinese Utility Model Patent Application Publication CN113637949A, while capable of comprehensively removing dust from each lens through its suction head and related design, significantly improving cleaning efficiency and reducing worker workload, suffers from a drawback: it can only coat a single layer of film. To apply the next layer, raw materials must be added again. This process not only requires adding materials but also involves repeated start-up and shutdown, vacuuming, and re-cleaning, severely reducing production efficiency. Furthermore, frequent opening and closing of the apparatus to add materials makes it easier for external dust and other impurities to enter the coating chamber, affecting coating quality and increasing the defect rate.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1 to 7This utility model provides a technical solution: a coating device for optical lens processing, including a mounting base 1 and an evaporation turntable 11. A top cover spring 2 and a turntable motor 7 are installed inside the mounting base 1. A top cover shaft 3 is fixedly connected to the top of the top cover spring 2. The upper end of the top cover shaft 3 is fixedly connected to a top cover 4 via top cover screws 5. The top cover 4 has a 90° notch for the turntable gear. Top cover retaining strips 6 are fixedly connected to the bottom of the top cover 4. The top cover spring 2 is in a stretched state during operation. There are four top cover retaining strips 6. The top cover screws 5 are designed to facilitate the removal of the top cover 4, allowing for easy removal of the evaporation turntable 11. The 90° notch for the turntable gear on the top cover 4 provides space for the evaporation and coating of the coating material; the material is rotated to the notch position for evaporation and coating. The top cover retaining strips 6 separate the various evaporation dishes 14 after rotation to prevent cross-contamination. The top cover shaft 3 is fixed by the top cover spring 2 and cannot rotate. A motor gear 8 is fixedly connected to the motor shaft of the turntable motor 7. A turntable gear 9 meshes with the side of the motor gear 8. A cross-shaped retaining strip 10 is engaged in the middle of the turntable gear 9, and the cross-shaped retaining strip 10 is movably sleeved on the outer surface of the top cover shaft 3. The turntable motor 7 drives the turntable gear 9 to rotate through the motor gear 8. The turntable gear 9 is connected to the evaporation turntable 11 through the cross-shaped retaining strip 10, so that the evaporation turntable 11 can rotate with the rotation of the turntable gear 9. A top cover groove 12 is opened on the top of the evaporation turntable 11, and a cross groove 13 is opened on the bottom of the top cover groove 12. Evaporation dishes 14 are installed on the upper surface of the evaporation turntable 11. There are four evaporation dishes 14. Heating coils 15 are installed inside the evaporation turntable 11 around the evaporation dishes 14. The top cover groove 12 cooperates with the top cover retaining strip 6 to achieve separation, and the cross groove 13 cooperates with the cross-shaped retaining strip 10 to form a fixation, thereby driving the evaporation turntable 11 to rotate. Four evaporating dishes 14 are used to hold the materials required for coating. Heating coils 15 are installed around the evaporating dishes 14 to heat them, causing the coating material to evaporate, thus achieving the coating operation. A wire groove 16 is provided inside the mounting base 1. A positive spring plate 17 and a negative spring plate 18 are installed on top of the wire groove 16. The positive and negative spring plates 17 and 18 are connected to an external power source through wires inside the wire groove 16. The wire groove 16 inside the mounting base 1 provides space for the wires to pass through. The positive and negative spring plates 17 and 18 are connected to an external power source through wires inside the wire groove 16 to provide power to the heating coils 15. A spring 19 is fixedly connected to the lower end of the positive and negative spring plates 17 and 18 away from the wire groove 16. The other end of the spring 19 is fixedly connected inside the mounting base 1. The spring 19 is installed at the bottom of the positive and negative spring plates 17 and 18, providing an upward elastic force to the spring plates. This ensures that the positive electrode spring plate 17 and the negative electrode spring plate 18 can make better contact with the two ends of the heating coil 15 during operation, thus guaranteeing the stability and reliability of the circuit connection.

[0028] In a preferred embodiment of this invention, the positive electrode spring 17 and the negative electrode spring 18 contact the two ends of the heating coil 15 at their upper ends during operation, and the bottom surface of the evaporation disc 11 is insulated. During operation, the upper ends of the positive electrode spring 17 and the negative electrode spring 18 contact the two ends of the heating coil 15, forming a complete circuit, allowing current to flow through the heating coil 15 and generate heat. The insulated bottom surface of the evaporation disc 11 prevents short circuits by stopping the contact with the coil during rotation. When the disc reaches the correct position, the spring 19 presses the spring plates against the two ends of the heating coil 15 to re-supply power, preventing malfunctions and dangers caused by leakage.

[0029] This device, designed to achieve the evaporation of various coating materials, should replace the evaporation dish component of the coating machine. During operation, the top cover spring 2 and top cover shaft 3 exert a downward force on the top cover 4, causing it to press tightly against the evaporation turntable 11. The top cover retainer 6 engages with the top cover groove 12, creating a sealed space between the top cover 4 and the evaporation turntable 11, separating the individual evaporation dishes 14. When adding coating material, after the first evaporation dish 14 is filled, the turntable motor 7 drives the cross retainer 10 to rotate via the motor gear 8 and turntable gear 9, which in turn rotates the evaporation turntable 11. As the turntable 11 rotates, the arc design of the top cover groove 12 causes the top cover 4 to move upwards against the tension of the top cover spring 2. The top cover groove 12 and the top cover retainer 6 disengage, and the evaporation turntable 11 rotates 90° before stopping, exposing the next evaporation dish 14 to the notch in the top cover 4 for easy addition of coating material. Simultaneously, under the tension of the top cover spring 2, the top cover retainer 6 re-engages with the rotated top cover groove 12 to form a seal. During the coating process, after completing the vacuuming and other processes of the coating machine, the positive and negative spring plates 17 and 18 are energized through the wires in the wire groove 16. At this time, the positive and negative spring plates 17 and 18 are in contact with the two ends of the corresponding heating coil 15 under the elastic force of the spring 19, energizing the heating coil 15. The heating coil 15 heats the inside of the evaporation dish 14 to the specified temperature, and the coating material in the evaporation dish 14 evaporates to coat the lens. After the coating layer is completed, the evaporation turntable 11 is rotated directly by the turntable motor 7. The top cover 4 separates the evaporation dishes 14 from each other in the same way as when adding coating material. During rotation, the positive and negative spring plates 17 and 18 will detach from the heating coil 15 and stop being energized. Because of the insulation treatment on the lower surface of the evaporation turntable 11, no circuit will be formed until the next heating coil 15 reaches the specified temperature, that is, there is no need to frequently switch the power supply on and off. After the evaporation turntable 11 rotates 90°, the next evaporation dish 14 moves to the heating position. The spring plate automatically forms a path with the heating coil 15 to heat the evaporation dish 14, completing the second coating. Through the above process, up to four layers of coating can be applied to the lens in one start-up of the coating machine, significantly reducing the workload of vacuuming and other tasks in the coating machine, reducing the number of times the lens comes into contact with the outside world, and improving the quality of the finished product.

[0030] In summary, this coating apparatus for optical lens processing, through the arrangement of the rotary motor 7 and the evaporation rotary table 11, enables the coating material to be moved sequentially to the evaporation point by rotating the evaporation rotary table 11 in the vacuum chamber. Multiple coating materials can be filled at once. Through the coordinated arrangement of the top cover spring 2, top cover shaft 3, top cover 4, top cover screw 5 and top cover retaining strip 6, during use, the top cover 4 can remain stationary while the evaporation rotary table 11 rotates to heat and evaporate the coating materials in different evaporation dishes 14 sequentially, thereby completing multi-layer coating. This avoids the need to refill the coating material for each coating, achieving the purpose of reducing workload and increasing work efficiency. This coating apparatus for optical lens processing, through the arrangement of evaporating dish 14 and heating coil 15, enables the coating apparatus to heat and evaporate the coating material in evaporating dish 14. Through the coordinated arrangement of wire groove 16, positive electrode spring plate 17, negative electrode spring plate 18 and spring 19, the mounting base 1 can be kept fixed during use. By rotating the evaporating turntable 11, different heating coils 15 are connected to the positive electrode spring plate 17 and the negative electrode spring plate 18 to complete the power supply heating. This avoids the design of requiring a separate power supply for each evaporating dish 14. A single power supply system can adapt to the working state of the rotating evaporating turntable 11, achieving the purpose of simplifying the structure and reducing costs.

[0031] 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.
