Description

Technical Field

[0001] This utility model relates to the field of optical window cleaning technology, specifically a sapphire optical window cleaning fixture. Background Technology

[0002] Sapphire optical windows are high-performance optical components based on synthetic sapphire. Due to their unique physical and chemical properties, they are widely used in many high-tech fields. Sapphire has a Mohs hardness of 9, second only to diamond, making it scratch-resistant and impact-resistant. Its melting point is as high as 2050℃, and it can operate stably at 1900℃ for extended periods, exhibiting high-temperature resistance far exceeding that of ordinary glass. Furthermore, its strong chemical stability allows it to resist corrosion from strong acids, strong alkalis, and fluorine-based plasmas, making it suitable for harsh environments such as semiconductor manufacturing.

[0003] Cleaning fixtures are required in the production of sapphire optical windows. Chinese utility model patent CN213915226U discloses a sapphire optical window cleaning fixture, belonging to the field of optical window processing jig technology. It includes an upper cover plate and a lower cover plate. The upper cover plate has several evenly distributed cleaning holes and a set of evenly distributed upper fixing holes on its side. The lower cover plate has several evenly distributed placement grooves and a set of evenly distributed lower fixing holes on its side. The cleaning holes and placement grooves are opposite in position and equal in number. The surface area of ​​the cleaning holes is smaller than the surface area of ​​the placement grooves. The upper fixing holes and lower fixing holes are opposite in position and equal in number. The lower cover plate also has several water flow channels surrounding the placement grooves, and adjacent water flow channels are interconnected. This utility model allows each diaphragm to be cleaned separately without accumulating during the cleaning process, effectively improving the cleaning quality of the optical window.

[0004] However, during use, because the placement slot is not hollow, although it can position and place the sapphire optical window, it cannot clean both sides of it at the same time during the cleaning process, which greatly reduces the cleaning efficiency and cannot meet the production requirements. Therefore, a sapphire optical window cleaning fixture is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sapphire optical window cleaning fixture, which has the advantage of facilitating cleaning of both sides of the sapphire optical window. It solves the problem that existing cleaning fixtures, due to their non-hollow placement slots, although able to position the sapphire optical window, cannot clean both sides simultaneously during the cleaning process, thus greatly reducing cleaning efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sapphire optical window cleaning fixture, comprising a mounting frame and two fixing plates respectively fixedly connected to the top and bottom of the mounting frame, wherein the mounting frame is provided with a linkage clamping mechanism capable of clamping and positioning the sapphire optical window.

[0007] The linkage clamping mechanism includes three sets of positioning clamping plates slidably connected inside the mounting frame. A first cylinder and a second cylinder are fixedly installed on the opposite side of the two fixed plates. A first movable rod and a second movable rod are fixedly connected to the output ends of the first cylinder and the second cylinder, respectively. A movable sleeve is slidably connected to the outside of the first movable rod, and a fixed sleeve is fixedly connected to the outside of the first movable rod. Both the fixed sleeve and the movable sleeve are fixedly connected to the positioning clamping plates.

[0008] Furthermore, each set of positioning clamping plates consists of two plates, with the top fixed sleeve fixedly connected to the second movable rod and the bottom movable sleeve slidably connected to the first movable rod.

[0009] Furthermore, the fixed sleeves and movable sleeves on the two positioning clamping plates are diagonally distributed, as are the first cylinder and the second cylinder.

[0010] Furthermore, the fixed sleeve and the movable sleeve are respectively fixedly connected to the positioning clamping plate with connecting blocks, and the interior of the mounting frame is provided with a limiting groove that matches the connecting blocks.

[0011] Furthermore, positioning grooves are provided on opposite sides of both positioning clamping plates, and silicone pads are fixedly connected to the inner walls of the positioning grooves.

[0012] Furthermore, the front of the mounting frame is fixedly connected with two handles, which are symmetrically distributed on the left and right sides of the front of the mounting frame.

[0013] Furthermore, a placement seat is provided on the back of the mounting frame, and a placement slot is provided on the side of the placement seat near the mounting frame. The number of placement slots is half the number of silicone pads.

[0014] Furthermore, a positioning rod extending into the mounting frame is fixedly connected to the front of the placement base, and a positioning groove adapted to the positioning rod is provided on the back of the mounting frame.

[0015] Compared with the prior art, the present invention provides a sapphire optical window cleaning fixture, which has the following advantages:

[0016] 1. This sapphire optical window cleaning fixture, by setting a first cylinder and a second cylinder, drives the first movable rod and the second movable rod to move in opposite directions. Consequently, the fixed sleeves on the first movable rod and the fixed sleeves on the second movable rod move in opposite directions, thereby driving the relative displacement of the two positioning clamping plates. This facilitates the clamping and positioning of the sapphire optical window. On the one hand, it can be applied to sapphire optical windows of different sizes, and on the other hand, it facilitates double-sided cleaning.

[0017] 2. This sapphire optical window cleaning fixture, with its placement base and slot, facilitates the positioning and placement of sapphire optical windows. This allows workers to clamp multiple sapphire optical windows simultaneously, improving work efficiency. It solves the problem of existing cleaning fixtures, where the placement slot is not hollow, which, although able to position and place sapphire optical windows, cannot clean both sides of the window simultaneously during the cleaning process, thus greatly reducing cleaning efficiency.
