[0002] Plastic titanium usually refers to TR90, a high molecular polymer widely used in eyewear manufacturing. It belongs to thermoplastic polyamide elastomers. Because it has the plasticity of plastic and the lightness and strength of titanium, it is called plastic titanium. It has the characteristics of low density, high impact resistance, durability and comfort.

[0003] The following technical problems were found in the existing technology: During the processing, transportation or manual assembly of eyeglass frames, oil stains, fingerprints, dust and other contaminants are easily left on the surface. Traditional pretreatment processes are difficult to completely remove micron-level contaminants. If coating is applied directly, the adhesion between the coating and the surface of the eyeglass frame will decrease, which may result in incomplete coating coverage, local peeling or orange peel-like surface, thus affecting the yield rate of the product.

[0004] The technical problem this utility model aims to solve is that during the processing, transportation, or manual assembly of eyeglass frames, contaminants such as oil, fingerprints, and dust are easily left on the surface. Traditional pretreatment processes are difficult to completely remove micron-level contaminants. If coating is applied directly, the adhesion between the coating and the surface of the eyeglass frame decreases, which may result in incomplete coating coverage, local peeling, or orange peel-like surface, thereby affecting the yield rate of the product.

[0005] The present invention relates to a plastic titanium mirror frame coating equipment, which includes a coating box, an ultrasonic cleaning module provided at the bottom of the inner side of the coating box, a liquid exchange port provided on the outer side of the ultrasonic cleaning module, and a coating assembly provided at the top of the inner side of the coating box. The cleaning component is located in the middle of the inner side of the ultrasonic cleaning module. The cleaning component includes a positioning mechanism and a material transfer component.

[0006] The cleaning assembly includes a filter box, a rotating shaft, a servo motor, and partitions. The filter box is fixedly connected to the middle of the inner side of the ultrasonic cleaning module. The rotating shaft is rotatably connected to the middle of the inner side of the filter box. The servo motor is fixedly connected to one side of the outer side of the coating box. The output end of the servo motor is fixedly connected to the rotating shaft. Multiple partitions are fixedly connected to the outer side of the rotating shaft.

[0007] The positioning mechanism includes a mating groove, a multi-stage telescopic rod, and a flexible clamping plate. The mating groove is provided on both sides of the outer side of the partition. Two sets of multi-stage telescopic rods are fixedly connected inside the ultrasonic cleaning module near the mating groove. The telescopic ends of the multi-stage telescopic rods are fixedly connected to the flexible clamping plate, which slides on the outer side of the partition.

[0008] The material transfer mechanism includes a mechanical claw, a partition plate, a material conveying trough, and a hook. The partition plate is fixedly connected to the middle of the inner side of the coating box. A material conveying trough is opened on the outer side of the partition plate.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] Example 1 like Figure 1 - Figure 4 As shown, a plastic titanium mirror frame coating equipment includes a coating box 1, an ultrasonic cleaning module 2 is provided on the bottom inner side of the coating box 1, a liquid exchange port 3 is provided on the outer side of the ultrasonic cleaning module 2, and a coating assembly is provided on the top inner side of the coating box 1. A cleaning component is located in the middle of the inner side of the ultrasonic cleaning module 2. The cleaning component includes a positioning mechanism and a material transfer component. The cleaning assembly includes a filter box 4, a rotating shaft 5, a servo motor 6, and partitions 7. The filter box 4 is fixedly connected to the inner center of the ultrasonic cleaning module 2. The rotating shaft 5 is rotatably connected to the inner center of the filter box 4. The servo motor 6 is fixedly connected to the outer side of the coating box 1. The output end of the servo motor 6 is fixedly connected to the rotating shaft 5. Multiple partitions 7 are fixedly connected to the outer side of the rotating shaft 5.

[0025] The positioning mechanism includes a mating groove 8, a multi-stage telescopic rod 9, and a flexible clamping plate 10. The mating groove 8 is provided on both sides of the outer side of the partition plate 7. Two sets of multi-stage telescopic rods 9 are fixedly connected inside the ultrasonic cleaning module 2 near the mating groove 8. The telescopic ends of the multi-stage telescopic rods 9 are fixedly connected to the flexible clamping plate 10, which slides on the outer side of the partition plate 7.

[0026] The material transfer mechanism includes a mechanical claw 11, a partition plate 12, a material conveying trough 13, and a hook 18. The partition plate 12 is fixedly connected to the middle of the inner side of the coating box 1. The material conveying trough 13 is opened on the outer side of the partition plate 12. The mechanical claw 11 is fixedly connected to the bottom of the outer side of the partition plate 12. The hook 18 is fixedly connected to the top of the inner side of the coating box 1.

[0027] The coating assembly includes a vacuum chamber 14, a drive module 15, an airflow generation module 16, and a magnetron sputtering target 17. Two sets of drive modules 15 are fixedly connected to the outside of the coating chamber 1, and two sets of vacuum chambers 14 are slidably connected to the inside of the coating chamber 1. The telescopic ends of the drive modules 15 are fixedly connected to the vacuum chambers 14. The airflow generation module 16 is fixedly connected to one side of the inside of the vacuum chambers 14, and multiple sets of magnetron sputtering targets 17 are fixedly connected to the middle of the inside of the vacuum chambers 14. The drive modules 15 can push the vacuum chambers 14 so that the two sets of vacuum chambers 14 come closer and fit together. The drive modules 15 have a vacuum pump integrated inside, which extracts the air inside the vacuum chambers 14 when the two sets of vacuum chambers 14 are fitted together, forming a vacuum environment inside the vacuum chambers 14.

[0028] During operation, the device is first connected to an external power supply, and then to an external control module. The electronic components in this technical solution are driven by the cooperation of the external control module and the power supply. The external control module is existing technology and should be well known to those skilled in the art, so it will not be described in detail in this technical solution.

[0029] During operation, when the eyeglass frame needs to be coated, cleaning fluid is injected into the ultrasonic cleaning module 2 through the fluid exchange port 3. Then, the staff places the eyeglass frame into the space formed by multiple sets of partitions 7 inside the ultrasonic cleaning module 2. Then, the servo motor 6 is driven to rotate the rotating shaft 5 and the partitions 7, which in turn drives the eyeglass frame into the cleaning fluid inside the ultrasonic cleaning module 2. When the eyeglass frame enters the cleaning fluid, the ultrasonic cleaning module 2 generates ultrasonic waves, which, in conjunction with the use of the cleaning fluid, cleans the extremely fine stains adhering to the outside of the eyeglass frame.

[0030] When the eyeglass frame sinks into the ultrasonic cleaning module 2, it falls into the filter box 4 due to gravity. The filter box 4 and the partition 7 are in contact with each other. The partition 7 continues to rotate, which can grab the eyeglass frame that has fallen into the filter box 4. Then it continues to rotate. When the eyeglass frame is at the top of the ultrasonic cleaning module 2, the servo motor 6 stops working. At this time, the multi-stage telescopic rod 9 begins to extend, which pushes the flexible clamp 10 to slide between the two sets of partitions 7. The flexible clamp 10 is made of flexible material. The eyeglass frame is positioned by the push of the two sets of flexible clamps 10. After positioning is completed, the multi-stage telescopic rod 9 begins to retract, and the flexible clamp 10 is taken into the mating grooves 8 on both sides of the partition 7, so that the partition 7 can continue to rotate smoothly. Then the mechanical claw 11 at the bottom of the partition box 12 grabs the eyeglass frame. The mechanical claw 11 is existing technology. It can be flexibly extended and retracted and its angle can be adjusted, which is convenient for grabbing objects with obstructions. Therefore, it will not be described in detail in this technical solution.

[0031] After the mechanical gripper 11 has finished gripping the eyeglass frame, it passes through the material conveying trough 13 and is suspended at the bottom of the hook 18. Then, the moisture on the surface of the eyeglass frame is allowed to drain naturally, reducing the impact of residual moisture on the coating effect. Next, the drive module 15 is driven to bring the two sets of vacuum chambers 14 on the top inner side of the coating chamber 1 closer together until they are completely in contact. Then, the drive module 15 extracts the air from the vacuum chambers 14, keeping the vacuum chambers 14 in a vacuum state. Then, the gas flow generation module 16 injects argon gas into the vacuum chambers 14 and applies voltage to coat the surface of the eyeglass frame by magnetron sputtering. The magnetron sputtering coating technology is existing technology and will not be described in detail in this technical solution. During the coating process, the hook 18 rotates continuously, making the coating effect more uniform.

[0032] By using cleaning components and material transfer mechanisms, the lens frames are ultrasonically cleaned and dried during magnetron sputtering coating. The flexible clamp 10 positions the lens frames, and then the mechanical claw 11 grips and installs the lens frames at the bottom of the hook 18. The entire process is automated, reducing the risk of recontamination due to worker contact after cleaning. This also reduces the impact of surface stains on the coating effect and product yield, further improving the practicality of the device.

[0033] Example 2 like Figure 1 - Figure 3 As shown, an infrared sensor 19 is fixedly connected to one side of the outer side of the coating box 1, an observation window 20 is provided on one side of the outer side of the vacuum chamber 14, and a sealing strip 21 is fixedly connected to the outer side of the vacuum chamber 14 near the hook 18.

[0034] During operation, when coating the eyeglass frame, the infrared sensor 19 is turned on. The infrared sensor 19 emits infrared rays and receives the reflected infrared rays. When a staff member or foreign object enters the coating chamber 1 and blocks the infrared sensor 19, the reflected infrared rays change, and the infrared sensor 19 sounds an alarm to remind of foreign object intrusion, further improving the safety and reliability of the coating process.

[0035] With the use of sealing strip 21 and observation window 20, when the vacuum chambers 14 are close to each other, the sealing strip 21 is squeezed, which further increases the sealing of the cavity formed by the two sets of vacuum chambers 14, reduces the entry of external air into the vacuum chamber 14, and allows the staff to observe the coating inside the vacuum chamber 14 through the observation window 20, which facilitates timely debugging of the device and further increases the practicality and reliability of the device.
