Description

Technical Field

[0001] This invention relates to the field of optical glass processing technology, and in particular to a coating apparatus for optical glass. Background Technology

[0002] Optical glass is a special type of glass material designed specifically for the optical field. It is used to manufacture core components such as lenses, prisms, mirrors, and windows in optical instruments or mechanical systems to achieve precise control and transmission of light. Its key differences from ordinary glass lie in its high optical transparency, precise and stable optical constants, extremely high chemical and physical homogeneity, and light transmission performance in specific wavelength ranges.

[0003] Optical glass coating equipment is the core equipment for depositing one or more precision thin films on the surface of optical elements to achieve functions such as anti-reflection, high reflectivity, spectral dispersion, and spectral filtering.

[0004] A coating apparatus for processing optical glass lenses, disclosed in Chinese patent CN221028655U, can uniformly coat lenses, solving the problem of time-consuming and labor-intensive manual flipping. However, compared with existing technologies and solutions, existing coating apparatuses still have the following problems in practical use: In actual use, existing coating equipment may cause edge chipping or microcracks in optical glass if rigid clamping is used, while flexible clamping may block the edges of the optical glass, creating coating blind spots and reducing the yield of the produced optical glass.

The electronic components, along with their associated control systems, power supply modules, circuits, and piping, can be provided by the manufacturer. Furthermore, all electronic components and control modules involved in this invention are existing technologies, fully capable of being implemented by those skilled in the art, and require no further explanation. This invention does not involve improvements to the structure or usage of electronic components.

[0027] The work process is as follows: S1. When using, first open the top cover 101, then place the optical glass to be coated between multiple fixed components 23, and rotate the adjusting screw 238 through the adjusting head 239. The adjusting screw 238 drives the slider 233 to move through the connecting seat 231, and the slider 233 drives the roller 234 to move. S2. When the roller 234 comes into contact with the optical glass, the slider 233 slides in the second groove 232, and the elastic element 235 contracts, so that the roller 234 abuts against the edge of the optical glass to fix the optical glass, avoiding excessive clamping force that could cause the optical glass to chip or crack, and at the same time avoiding obstruction of the edge of the optical glass to form a coating blind area, thereby improving the yield of the produced optical glass. S3. Next, slide the sliding seat 224 along the first sliding groove 214 on the second connecting plate 213 to adjust the angle between the connecting rod 223 and the gear 221, thereby adjusting the position of the optical glass. After the adjustment is completed, tighten the fixing bolt 225 to fix the angle. S4. Close the top cover 101 and fix the top cover 101 with the fastener 103. Then start the drive unit 211. The drive unit 211 drives the transmission assembly 22 to rotate through the first connecting plate 212. S5. Since gear 221 meshes with gear ring 105, gear 221 rotates along with the first connecting plate 212 and rotates on its own axis. It drives connecting rod 223 through universal joint 222. Connecting rod 223 drives optical glass fixed in connecting ring 226 by fixing component 23 through connecting ring 226 to rotate, ensuring the uniformity of coating and further improving the quality of produced optical glass.
