[0022] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0023] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0024] Please refer to Figures 1-5 This utility model proposes an ultrasonic cleaning structure for optical components before and after plating, including a three-stage sewage discharge device on the cleaning machine.

[0025] The three-stage sewage discharge device is provided with a second cleaning tank 2, a third cleaning tank 4 and a fourth cleaning tank 8 in sequence. The second cleaning tank 2 and the third cleaning tank 4 are separated by a first side barrier structure 3. The third cleaning tank 4 and the fourth cleaning tank 8 are separated by a second side barrier structure 9. A first sewage pipe 5 is provided in the second side barrier structure. The first sewage pipe 5 connects one side of the top of the fourth cleaning tank 8 and one side of the bottom of the third cleaning tank 4. The first side barrier structure 3 is inclined from the third cleaning tank 4 to the second cleaning tank 2. A second sewage pipe 1 is provided on one side of the top of the second cleaning tank 2.

[0026] In a specific embodiment, the second cleaning tank 2 is filled with pure water. During cleaning, the optical components are generally placed in this tank for ultrasonic rinsing at a certain time and temperature. The cavitation effect of the ultrasonic waves is used to remove and rinse away the residual dirt and cleaning agent. The third cleaning tank 4 is also filled with pure water. During cleaning, the optical components cleaned in the second cleaning tank 2 are generally placed in the third cleaning tank 4 for ultrasonic rinsing at a certain time and temperature. The cavitation effect of the ultrasonic waves is mainly used to remove and rinse away the residual dirt and cleaning agent. The fourth cleaning tank 8 is a slow-pull tank.

[0027] Pure water is added to the fourth cleaning tank 8 for cleaning. When the water level overflows, it flows into the third cleaning tank 4 through the first drain pipe 5. When pure water is injected into the third cleaning tank 4, the dirt and residual cleaning agent that have been rinsed by ultrasonic cavitation in the third cleaning tank 4 overflow with the water level and enter the second cleaning tank 2 through the first baffle structure 3. As the water volume in the second cleaning tank 2 increases, the pure water overflows from the second cleaning tank 2 and is discharged through the first drain pipe 5. Through the three-stage drainage device, pure water is continuously added to the fourth cleaning tank 8 to remove dirt during the ultrasonic cleaning process, avoid secondary contamination of optical components, improve cleaning efficiency, and achieve a high-cleanliness cleaning process for optical components before and after plating.

[0028] Furthermore, it also includes an inlet pipe 11 and an outlet pipe 10. The inlet pipe 11 is connected from the bottom to the second cleaning tank 2, the third cleaning tank 4 and the fourth cleaning tank 8 respectively, and the outlet pipe 10 is connected from the bottom to the first drain pipe 5, the second drain pipe 1, the second cleaning tank 2, the third cleaning tank 4 and the fourth cleaning tank 8 respectively.

[0029] In a specific implementation, the inlet pipe 11 is used to introduce pure water, and the outlet pipe 10 is used to discharge liquid. When cleaning begins, pure water is introduced into the inlet pipe 11, and after cleaning is completed, the waste liquid in the second cleaning tank 2, the third cleaning tank 4 and the fourth cleaning tank 8 is discharged through the outlet pipe 10.

[0030] Furthermore, the fourth cleaning tank 8 also includes a top stepped portion 14, and a third baffle structure 6 is provided on the inner edge of the stepped portion 14.

[0031] In a specific embodiment, the cross-section of the fourth cleaning tank 8 is T-shaped, and the third baffle structure 6 is located on the inner edge of the top step 14 of the fourth cleaning tank 8. When pure water passes through the third baffle structure 6, the speed will be slowed down by the third baffle structure 6, so that the pure water immersing into the first drain pipe 5 is slower.

[0032] Furthermore, the third side rail structure 6 is gear-shaped.

[0033] In specific implementations, the third sidewall structure 6 can also be selected from other shapes, such as a mesh structure, depending on the actual situation.

[0034] Furthermore, a mechanical device 7 is also provided in the fourth cleaning tank 8, which is used to lift and move the optical element.

[0035] In a specific embodiment, the mechanical device 7 vertically lifts the optical element in the fourth cleaning tank 8 and slowly pulls it, using the surface tension of the water to remove most of the water on the lens, so as to prevent watermarks and stains from appearing on the cleaned optical element during the drying process, which would affect the optical performance of the optical element.

[0036] Furthermore, it also includes a first cleaning tank 12 and a drying tank 13 on the cleaning machine. The first cleaning tank 12 is used for cleaning agent and ultrasonic cleaning, and the drying tank 13 is used for high-temperature hot air drying.

[0037] In a specific embodiment, the first cleaning tank 12 is a cleaning liquid tank. Pure water and optical component cleaning agent are mixed in the first cleaning tank 12 in a certain proportion to perform ultrasonic cleaning of the optical components at a certain temperature and frequency. The cleaning agent, together with the cavitation effect of the ultrasonic equipment, softens, removes and dissolves the stains on the optical components. The drying tank 13 is used to dry the optical components after the slow drawing process with hot air for a certain period of time to ensure that the optical components are dry.

[0038] Furthermore, the cleaning process for ultrasonic cleaning structures of optical components before and after plating proposed in this utility model includes the following steps:

[0039] S1. Place the optical element in the first cleaning tank 12, and add a cleaning solution and pure water mixed in a ratio of 1:19 to form an optical cleaning agent. Then add the optical cleaning agent and pure water in a ratio of 1:15 to the first cleaning tank 12, heat the liquid in the first cleaning tank 12 to 50 degrees Celsius, and perform ultrasonic cleaning for 600-620 seconds.

[0040] S2. After cleaning is completed in the first cleaning tank 12, the optical element is moved to the second cleaning tank 2, the pure water in the second cleaning tank 2 is heated to 30 degrees Celsius, and ultrasonic cleaning is performed in a static state for 200 seconds.

[0041] S3. Move the optical components into the third cleaning tank 4 and use pure water heated to 30 degrees Celsius in conjunction with ultrasonic waves for flowing rinsing.

[0042] S4. Repeat steps S2-S3 at least three times, then place the rinsed optical element into the fourth cleaning tank 8, continuously pass pure water into the fourth cleaning tank 8 and slowly lift the optical element, controlling the lifting speed to 2mm / s.

[0043] S5. Move the slowly pulled optical element into the drying tank 13 and dry it with hot air at 90 degrees Celsius for 5 minutes.

[0044] In a specific implementation, only the first cleaning tank 12 contains cleaning fluid, while the second, third, and fourth cleaning tanks 2 and 4 contain pure water. The pure water used in all cleaning tanks has a resistivity of 15 MΩ, and the ultrasonic frequency is 40 kHz. The ratio of optical component cleaning agent to pure water in the first cleaning tank 12 is 1:19. During the entire cleaning process, pure water is continuously introduced into the fourth cleaning tank 8. The pure water overflows from the fourth cleaning tank 8 and enters the bottom of the third cleaning tank 4 through the first drain pipe 5. As the amount of pure water in the third cleaning tank 4 increases, the dirt on the optical components at the bottom of the third cleaning tank 4 will be carried away by the pure water. Similarly, the dirt on the top of the second cleaning tank 2 will also be carried away by the pure water overflowing from the first baffle structure 3 in the third cleaning tank 4 and discharged into the second drain pipe 1. During the cleaning of the optical components, dirt can be removed in real time. At the same time, a relatively small amount of cleaning agent can be used to achieve a high degree of cleanliness of the optical components before and after coating, ensuring that the coating layer of the optical components will not peel off.

[0045] In one embodiment, since the cleaning agent is usually a neutral one to prevent the film layer from peeling off after cleaning the optical components due to excessive corrosiveness, the cleaning agent needs to be soaked before ultrasonic cleaning. That is, soaking, ultrasonic cleaning, rinsing, slow pulling, and drying are performed in sequence. However, the present invention uses a three-stage sewage discharge device to use the cleaning agent as a solvent in the first cleaning tank 12 for cleaning, which can reduce the specific soaking process while ensuring the cleanliness of the optical components.

[0046] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
