Description

Technical Field

[0001] The utility model relates to the technical field of optical glass coating, in particular to an optical glass coating device. Background Art

[0002] Optical glass is a special glass material that can change the direction of light propagation and alter the relative spectral distribution of ultraviolet, visible, or infrared light. This type of glass is widely used in the field of optics, primarily in the manufacture of lenses, prisms, reflectors, and windows in optical instruments or mechanical systems. To achieve requirements such as reducing or increasing light reflection, beam splitting, color separation, filtering, and polarization, it is usually necessary to coat the surface of optical components with one or more layers of metal (or dielectric) thin film. Common coating methods include vacuum coating (a type of physical coating) and chemical coating.

[0003] After the optical glass is coated, in order to check the pass rate of the optical glass coating, special testing equipment is generally required for testing. However, the existing optical glass coating equipment generally does not have a testing part, resulting in the optical glass coating not being able to get timely feedback. In addition, when testing the optical glass, the optical glass needs to be transferred to other testing equipment. During the transfer process, the staff needs to carefully remove the coated optical glass from the coating equipment, place it on the transfer tool, and then transport it to the testing equipment. This series of operations is not only time-consuming, but also requires the operator to have high professional skills and carefulness to avoid damaging the coating layer or the glass itself during the transfer process.

[0004] Therefore, it is necessary to design a coating device for optical glass. Utility Model Content

The front side of the placement box 14 is symmetrically connected with a feed pipe 16. A discharge pipe 17 is symmetrically installed inside each splashing machine 12, and the discharge end of the feed pipe 16 is connected to the discharge pipe 17 inside the adjacent splashing machine 12. A rotating drum 18 is symmetrically installed inside each splashing machine 12 through a bearing. The rotating drum 18 is located between two adjacent discharge pipes 17.

[0023] Before the coating work begins, preparation work needs to be done. First, connect the external water pipe to the water inlet pipe 4 on the water tank 3, and pour an appropriate amount of materials needed for coating into the placement box 14 from the feed port 15. After pouring, the equipment can be powered on, so that the sprinkler 5, inflator 7, increaser 10 and splasher 12 start working, and the transmission assembly on the base 1 starts working. The staff puts the optical glass on the first base 1, and the optical glass is transported to the right by the transmission assembly. First, the optical glass will come to the bottom of the sprinkler 5, and the sprinkler 5 will splash clean water on the optical glass. The surface of the optical glass is cleaned by washing the dust and impurities on the surface of the optical glass. The cleaned optical glass will come to the bottom of the air knife 9. The inflator 7 can output the gas from the air supply pipe 8 and the air knife 9, so that the air knife 9 can dry the moisture on the surface of the optical glass. The dried optical glass will pass under the increaser 10. The pressure pump 11 will reduce the atmospheric pressure to create a vacuum environment for vacuum coating. Then the optical glass will come to the bottom of the splash machine 12. Since there are five splash machines 12, the optical glass will pass under the five splash machines 12 in sequence. , realizing a multi-layer coating composite process, at this time, the coating material in the placement box 14 will be transported to the discharge pipe 17 through the feeding pipe 16, and the rotation of the drum 18 can cause the charged ions to collide with the drum 18, so that the metal oxide atoms will fall off from the drum 18 and fuse to the surface of the optical glass. The metal particles will be selectively adsorbed on the surface and at the same time make the optical glass have special optical properties and heat insulation properties. In this way, the optical glass can realize the vacuum coating process of the optical glass after the above process. When the optical glass is transported to the bottom of the fixing frame 20, The air pressure gradually returns to normal. Simultaneously, as the optical glass passes beneath the inclined plate 26 and support member 27, the detector 25 is forced upward, compressing the first spring 24. When the optical glass leaves the inclined plate 26 and support member 27, the detector 25, forced downward by the first spring 24, resets. The detector 25 can quickly determine whether the thickness meets the requirements. Unqualified products are reported in real time via the display 191, facilitating prompt processing by staff. The display 191 also activates the alarm 192, providing enhanced notification. Repeating the above steps allows the coating process and testing to be performed on the next piece of optical glass. When vacuum coating is no longer required, simply power off the equipment. The design of the electric slide 21 allows the distance between the two detectors 25 to be adjusted to accommodate different optical glass specifications. The design of the support member 27, second spring 28, and guide plate 29 restricts the transport trajectory of the optical glass as it passes between them, preventing it from swinging during transport.

[0024] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
