Description

Technical Field

[0001] This invention belongs to the field of optical element technology, and specifically relates to an optical element irregular shape coating tooling. Background Technology

[0002] Some optical components require irregularly shaped coatings on their surfaces, meaning that their surfaces are not coated with conventional shapes such as circles or rectangles, but rather with irregular shapes such as ellipses or stars in specific areas of the optical component's surface.

[0003] Currently, most of the tooling fixtures used for coating are for coating conventionally shaped films such as round or rectangular films. Some tooling fixtures have also been designed and developed for coating irregularly shaped films. However, irregular shapes are diverse, and different tooling fixtures need to be changed when coating different irregularly shaped films, resulting in a large number of tooling fixtures used and high costs. Summary of the Invention

[0004] The purpose of this invention is to provide an optical element irregular shape coating fixture. This fixture can coat both conventional circular films and various irregular shapes. When coating irregular shapes, the irregular coating element can be replaced and installed in the coating hole according to the required shape. Without installing the irregular coating element, it can coat conventional circular films normally. By simply replacing one irregular coating element, the coating requirements for various shapes can be met.

[0005] The specific technical solution adopted by this invention is as follows: An optical element irregular shape coating fixture includes a coating disk, wherein the coating disk is provided with at least one optical element fixing groove, and the at least one optical element fixing groove is provided with at least two symmetrical fixing holes; It also includes a pressure plate, which is used to fix the optical element in the optical element fixing groove, wherein the pressure plate has a coating hole at the center and a step is provided in the coating hole; It also includes irregularly shaped coating elements, which are used to be installed in the coating hole during the coating process and clamped and fixed to the optical element by steps.

[0006] In a preferred embodiment of the present invention, the pressure plate is fixedly connected to the coating disc by bolts.

[0007] As a preferred embodiment of the present invention, the irregularly shaped coating element is a disk that matches the coating hole, and the irregularly shaped hole is formed on the disk.

[0008] As a preferred embodiment of the present invention, the irregular hole includes polygons, triangles, and ellipses.

[0009] As a preferred embodiment of the present invention, a buffer pad layer is provided on the surface of the irregularly shaped coated element.

[0010] As a preferred embodiment of the present invention, the optical element is placed higher than the optical element fixing groove when it is placed in the optical element fixing groove. The technical effects achieved by this invention are as follows: The optical element irregular shape coating fixture provided by this invention can coat both conventional circular films and various different irregular shapes. When coating irregular shapes, it is only necessary to replace the irregular shape coating element into the coating hole according to the required shape. Without installing the irregular shape coating element, it can coat conventional circular films normally. By simply replacing one irregular shape coating element, the coating requirements of various shapes can be met. Attached Figure Description

[0017] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0020] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth. Example 1

[0021] Combination Figure 1 and Figure 2 An optical element irregular shape coating fixture includes a coating disk 1, on which at least one optical element fixing groove 4 is provided. The specific setting can be set as needed and is not limited. The at least one optical element fixing groove 4 is configured with at least two symmetrical fixing holes.

[0022] It also includes a pressure plate 2, which is used to fix the optical element in the optical element fixing groove 4. The pressure plate 2 has a coating hole 22 at its center and a step 21 is provided inside the coating hole 22. It also includes an irregularly shaped coating element 3, which is used to be installed in the coating hole 22 during the coating process and clamped and fixed to the optical element by the step 21.

[0023] In this embodiment, during coating, the optical element is first placed in the optical element fixing groove 4 in the coating disk 1. If a circular film needs to be coated, there is no need for the irregularly shaped coating element 3. The pressure plate 2 is directly pressed onto the upper surface of the optical element. The upper surface part of the optical element is placed into the coating hole 22 and the edge of the upper surface of the optical element is pressed together by the step 21. The pressure plate 2 is fixed to the coating disk 1 by bolts to fix the optical element. Then, the exposed part of the optical element is coated through the coating hole 22. When it is necessary to coat irregularly shaped films, the optical element is first placed in the optical element fixing groove 4, and then the irregularly shaped coating element 3 is placed at the step 21 in the coating hole 22. Then, the pressure plate 2 is pressed onto the upper surface of the optical element. At this time, part of the upper surface of the optical element will still be placed into the coating hole 22. The irregularly shaped coating element 3 and the optical element are pressed and fixed at one time through the step 21 in the coating hole 22, and the pressure plate 2 is fixed again by bolts. At this time, the corresponding irregularly shaped film is coated on the exposed upper surface of the optical element through the irregularly shaped hole 31 on the irregularly shaped coating element 3.

[0024] In this embodiment, the irregularly shaped coating element 3 is a disk that matches the coating hole 22, and an irregularly shaped hole 31 is formed on the disk. The irregularly shaped hole 31 is polygonal. To prevent the irregularly shaped coating element 3 from damaging the surface of the optical element, a buffer pad layer is applied to the surface of the irregularly shaped coating element 3. Furthermore, it is understood that when the optical element is placed in the optical element fixing groove 4, it protrudes above the upper edge of the optical element fixing groove 4. Example 2
