Description

Technical Field

[0001] This utility model relates to the field of space mirror processing technology, specifically a space mirror vacuum coating fixture. Background Technology

[0002] A space mirror is an optical element that works using the law of reflection. Mirrors can be classified into three types according to their shape: plane mirrors, spherical mirrors, and aspherical mirrors; and according to their degree of reflection: total reflection mirrors and semi-reflective mirrors. When manufacturing mirrors, silver is often plated onto the glass. The standard manufacturing process involves vacuum evaporating aluminum onto a highly polished substrate, followed by plating with silicon monoxide or magnesium fluoride. In special applications, losses caused by the metal can be replaced by multilayer dielectric films. Because the law of reflection is independent of the frequency of light, this type of element has a very wide operating bandwidth, reaching the ultraviolet and infrared regions of the visible light spectrum, thus its application range is becoming increasingly wide. A thin film of metallic silver (or aluminum) is deposited on the back of the optical glass through vacuum coating to reflect incident light. Using a high-reflectivity mirror can multiply the output power of a laser; and since it is the first reflecting surface, the reflected image is undistorted and without ghosting, representing front surface reflection. Using a conventional mirror as the second reflecting surface results in low reflectivity, lack of wavelength selectivity, and a tendency to produce ghosting. In contrast, using a coated mirror produces images with high brightness, high precision, and clearer, more realistic colors. Front-surface mirrors are widely used for high-fidelity optical scanning and reflection imaging. Space mirrors require vacuum coating during manufacturing.

[0003] Current vacuum coating of space reflectors requires clamping and limiting. Existing clamping and limiting devices are generally fixed in structure, which cannot be quickly installed and disassembled according to actual needs, resulting in low overall processing efficiency. At the same time, the processing cannot be automatically flipped and changed, which requires manual intervention and is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a vacuum coating fixture for space mirrors to solve the problem mentioned in the background art that the current vacuum coating of space mirrors requires clamping and limiting, and the existing clamping and limiting devices are generally fixed in structure, which cannot be quickly installed and disassembled according to actual needs, resulting in low overall processing efficiency. At the same time, the processing process cannot be automatically flipped and changed, resulting in the need for manual intervention, which is time-consuming and labor-intensive.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum coating fixture for a space reflector, comprising a rotating bracket, a connecting column rotatably mounted on the inner side of the rotating bracket, a clamping ring provided at one opposite end of each connecting column, an electric push rod surrounding the inner surface of each clamping ring, a clamping seat provided at one opposite end of each electric push rod, an adjusting rod movably mounted through one side surface of each clamping seat, and a contact plate rotatably mounted at one end of each adjusting rod.

[0006] Preferably, a positioning block is provided on one side surface of the rotating bracket, the positioning block is provided with a positioning screw hole on its surface, and a positioning bolt is movably provided on the inner side of the positioning screw hole.

[0007] Preferably, a rotary motor is provided on one side of the top of the rotary support, the output end of the rotary motor passes through the rotary support and is connected to one end of the connecting column, and a diagonal brace is provided on one side surface of the rotary motor.

[0008] Preferably, a rotating shaft is provided at the connection between the connecting column and the rotating bracket, and a bearing is provided at the connection between the adjusting rod and the contact plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This vacuum coating fixture for space reflectors can be adjusted according to the size and thickness of the space reflectors to be coated. An electric push rod drives the clamping seat to engage with the end of the space reflector. The outer edge of the space reflector is placed inside the clamping seat. The adjustment rod is manually turned on the threaded surface of the clamping seat to move and adjust the bottom contact plate, thereby clamping and limiting the outer edge of the space reflector. This makes the coating clamping less restrictive and more flexible.

[0013] This vacuum coating fixture for space reflectors can be started and run in real time according to the actual vacuum coating needs. The rotating motor drives the connecting column and clamping ring to rotate, thereby rotating the space reflector and realizing the face-changing during the coating process. This avoids omissions and dead corners in the coating process, replaces the traditional manual face-changing operation, saves manpower and material resources, and improves the overall efficiency of coating.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4As shown, this utility model provides a technical solution: a vacuum coating fixture for a space reflector, including a rotating bracket 8. A connecting column 1 is rotatably mounted on the inner side of the rotating bracket 8. According to the actual needs of vacuum coating, a rotating motor 10 is started to operate in real time. The rotating motor 10 drives the connecting column 1 and the clamping ring 7 to rotate, thereby rotating the space reflector and realizing the face-changing during the coating process, avoiding omissions and dead angles in the coating, replacing the traditional manual face-changing operation. A clamping ring 7 is provided at one opposite end of the connecting column 1. An electric push rod 5 is arranged around the inner surface of the clamping ring 7. A clamping seat 6 is provided at one opposite end of the electric push rod 5. An adjusting rod 12 is movably mounted through one side surface of the clamping seat 6. One end of the 12 is rotatably equipped with a contact plate 13. Depending on the size and thickness of the space reflector to be coated, the electric push rod 5 drives the clamping seat 6 to engage with the end of the space reflector. The outer edge of the space reflector is placed inside the clamping seat 6. The adjustment rod 12 is manually twisted on the surface of the clamping seat 6 to move and adjust the bottom contact plate 13, thereby clamping and limiting the outer edge of the space reflector. This makes the coating clamping less restrictive and more flexible. One side surface of the rotating bracket 8 is equipped with a positioning block 3. The surface of the positioning block 3 is equipped with a positioning screw hole 15, and the inner side of the positioning screw hole 15 is movably equipped with a positioning bolt 2, which can connect the entire clamp to the coating device and prevent it from falling off automatically during use.

[0021] A rotary motor 10 is installed on one side of the top of the rotating bracket 8. The output end of the rotary motor 10 passes through the rotating bracket 8 and connects to one end of the connecting column 1, providing sufficient driving force for the flipping surface. A diagonal brace 9 is installed on one side of the rotary motor 10 to increase the stability of the rotary motor 10 and prevent it from being suspended in the air, which would affect normal operation. A rotating shaft 4 is installed at the connection between the connecting column 1 and the rotating bracket 8, and a bearing 16 is installed at the connection between the adjusting rod 12 and the contact plate 13, allowing the contact plate 13 and the adjusting rod 12 to rotate relative to each other, avoiding jamming during the adjustment process. An adjusting knob 11 is installed on the outer end of the adjusting rod 12, and threads are installed on the surface of the adjusting rod 12 and the through connection of the clamping seat 6. The friction generated by the threaded engagement drives the adjusting rod 12 to move, thereby adjusting the clamping space. A limit pad 14 is installed on one side of the inner wall of the clamping seat 6, and the limit pad 14 is made of rubber, which increases the softness of the space reflector clamping contact and avoids damage to the mirror body caused by rigid contact.

[0022] Working principle: When vacuum coating of a space reflector is required, the fixture is first installed in the corresponding position of the vacuum coating device using the positioning block 3 and positioning bolt 2. Then, depending on the size and thickness of the space reflector to be coated, the electric push rod 5 drives the clamping seat 6 to engage with the end of the space reflector, placing the outer edge of the space reflector into the inner side of the clamping seat 6. The adjusting rod 12 is manually twisted on the threaded surface of the clamping seat 6, thereby moving and adjusting the bottom contact plate 13 to clamp and limit the outer edge of the space reflector, making the coating clamping less restrictive and more flexible. At the same time, according to the actual vacuum coating needs, the rotary motor 10 can be started in real time. The rotary motor 10 drives the connecting column 1 and the clamping ring 7 to rotate, thereby rotating the space reflector and realizing the face-changing during the coating process, avoiding omissions and dead corners in the coating, and replacing the traditional manual face-changing operation.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
