Description

Technical Field

[0001] The utility model relates to the technical field of coating processing of corner cube prisms, and particularly relates to a coating layer protection device for deep processing of corner cube prisms. Background Technique

[0002] A corner cube prism is an optical element that can reflect incident light back along the original path. To improve the performance and durability of the corner cube prism, the corner cube prism is usually placed in a protection device so that the protected area of the corner cube prism will not be coated. Then, the corner cube prism and the protection device are placed in a vacuum coating chamber, and the coating material is bombarded by ions, and the sputtered particles are deposited on the prism surface to coat one or more layers of thin films on the surface of the corner cube prism. These thin films can be reflective films, anti-reflective films, or protective films, etc.

[0003] After retrieval, the Chinese patent "A Coating Protection Device for Corner Cube Prisms" with the authorization announcement number "CN220745724U" clamps the inner ring of the open loop at the lower end of the surface of the corner cube prism by rotating the bolt, and directly covers the base of the circular clamp with a coating protection cover to enclose the upper end of the surface of the corner cube prism, so that the cylindrical bottom surface and the three right-angled surfaces of the corner cube prism can be effectively separated during coating. The coating protection cover can protect the cylindrical bottom surface and the triangular pyramid section of the corner cube prism respectively during coating.

[0004] The above-mentioned method of directly covering the coating protection cover on the base of the circular clamp results in a loose connection between the coating protection cover and the base of the circular clamp, and particles are likely to enter the inside of the coating protection cover during vacuum coating, thereby affecting the protection effect on the corner cube prism.

[0005] Therefore, a coating layer protection device for deep processing of corner cube prisms is proposed to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a coating layer protection device for deep processing of corner cube prisms to solve the above problems, and improve the problem that particles are likely to enter the inside of the coating protection cover during vacuum coating.

[0007] The present utility model achieves the above object through the following technical solutions.

Through the plugging block, the bottom end of the base is plugged and the bottom end of the corner cube prism is supported, avoiding the additional use of bolts to position the lower end of the surface of the corner cube prism inside the fixture, and avoiding the coating particles from splashing onto the bottom end of the corner cube prism during the coating of the upper end of the surface of the corner cube prism, ensuring the protection effect on the corner cube prism.

[0009] Preferably, a magnetic ring is fixedly connected to the upper end of the inner wall of the plugging block, and the top end of the magnetic ring is magnetically attracted to the bottom end of the iron ring. Through the magnetic ring and the iron ring, the plugging block is stably stuck at the opening at the bottom end of the base, ensuring the plugging effect on the bottom end of the corner cube prism.

[0010] Preferably, a soft pad is fixedly connected to the inner top wall of the protective cover. Through the soft pad, flexible contact is achieved at the apex of the corner cube prism, improving the protection effect of the protective cover on the upper end of the surface of the corner cube prism.

[0011] Preferably, a protective block is fixedly connected to the surface of the fixing frame, and the surface of the protective block contacts the lower end of the surface of the base. Through the protective block, the opening at the upper end of the surface of the base is plugged, preventing impurities from entering the inner wall of the base.

[0012] Preferably, a movable ring is rotatably connected to the bottom end of the screw rod.

[0013] Preferably, a stop rod is fixedly connected to the bottom end of the movable ring, and the surface of the stop rod is sequentially slidably connected to the inner walls of the base and the fixing frame. Through the movable ring and the movable ring, the upward movement position of the screw rod is restricted, preventing the screw rod from disengaging from the inside of the fixing frame during upward movement, and thus avoiding the inconvenience of aligning the screw rod with the thread on the fixing frame later.

[0014] Preferably, the upper end of the surface of the mounting block is V-shaped.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. Through the protective cover and the silica gel ring, the inner side of the silica gel ring is attached to the lower end of the surface of the fixture. Through the screw, the fixing frame and the mounting block, the bottom end of the protective cover is fixed to the top end of the base, so that the protective cover is tightly connected to the base, ensuring the protection effect on the upper end of the surface of the corner cube prism by the protective cover;

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] During specific implementation: As Figures 1-4As shown in the figure, a coating layer protection device for deep processing of a corner cube prism includes: a base 1, a fixture 2 fixedly connected to the top end of the base 1, and a protective cover 3 provided at the top end of the base 1; a sealing mechanism 4 provided on the surface of the base 1; wherein, the sealing mechanism 4 includes a silicone rubber ring 41 fixedly connected to the lower end of the inner wall of the protective cover 3, an annularly distributed mounting block 42 fixedly connected to the top end of the base 1, a fixing frame 43 slidably connected to the inner wall of the base 1, the upper end of the surface of the fixing frame 43 is slidably connected to the mounting block 42 and the inner wall of the protective cover 3 in sequence, a screw rod 44 is threadedly connected to the top of the fixing frame 43, the lower end of the surface of the screw rod 44 is threadedly connected to the top of the base 1, a soft pad 410 is fixedly connected to the inner top wall of the protective cover 3, and the upper end surface of the mounting block 42 is V-shaped. The soft pad 410 is a silicone member.

[0025] When it is necessary to coat the bottom end of the corner cube prism, the corner cube prism is placed in the fixture 2. Since the inner side of the fixture 2 matches the size of the lower end surface of the corner cube prism, the inner side of the fixture 2 fits on the lower end surface of the corner cube prism. The mounting block 42 with a V-shaped upper end surface enables the bottom end of the protective cover 3 to accurately and quickly cover the top end of the base 1, making the inner side of the silicone rubber ring 41 fit on the lower end surface of the fixture 2, and the bottom end of the soft pad 410 makes flexible contact with the apex of the corner cube prism. Push the fixing frame 43, and the upper end of the surface of the fixing frame 43 moves to the corresponding position on the mounting block 42 and the inner wall of the protective cover 3. Rotate the screw rod 44 so that the screw rod 44 is threaded into the fixing frame 43 and the base 1 in sequence, and the protective cover 3 is tightly installed on the base 1. At this time, the base 1 and the protective cover 3 are placed upside down in a vacuum coating chamber to perform vacuum coating on the bottom end of the corner cube prism.

[0026] As Figure 2 shown, a plugging block 45 is clamped at the bottom end of the base 1, an iron ring 46 is fixedly connected to the lower end of the inner wall of the base 1, a magnetic ring 411 is fixedly connected to the upper end of the inner wall of the plugging block 45, and the top end of the magnetic ring 411 is magnetically attracted to the bottom end of the iron ring 46. The magnetic ring 411 is a high-temperature ferrite member.

[0027] When coating the upper end surface of the corner cube prism, the plugging block 45 is clamped at the bottom end of the base 1. Through the magnetic ring 411 and the iron ring 46, the plugging block 45 is positioned at the bottom end of the base 1 to plug the opening at the bottom end of the base 1. At this time, the corner cube prism is placed in the fixture 2, the inner side of the fixture 2 fits on the lower end surface of the corner cube prism, the bottom end of the corner cube prism contacts the top end of the plugging block 45, and the lower end surface of the corner cube prism is closely attached to the base 1. At this time, the base 1 is placed in a vacuum coating chamber to perform vacuum coating on the upper end surface of the corner cube prism.

[0028] As Figure 4 shown, a protective block 47 is fixedly connected to the surface of the fixing frame 43, and the surface of the protective block 47 contacts the lower end surface of the base 1.

The surface of the stop rod 49 is sequentially slidably connected to the inner walls of the base 1 and the fixing frame 43.

[0030] When the present utility model is in use, a corner cube prism is placed into the fixture 2. Since the inner side of the fixture 2 matches the size of the lower end surface of the corner cube prism, the inner side of the fixture 2 fits against the lower end surface of the corner cube prism. The mounting block 42 with a V-shaped upper end surface enables the bottom end of the protective cover 3 to accurately and quickly cover the top end of the base 1. The inner side of the silica gel ring 41 fits against the lower end surface of the fixture 2, and the bottom end of the soft pad 410 is in flexible contact with the apex of the corner cube prism. The fixing frame 43 is pushed, and the upper end surface of the fixing frame 43 moves to the corresponding position on the inner walls of the mounting block 42 and the protective cover 3. The screw rod 44 is rotated, so that the screw rod 44 is sequentially threaded into the fixing frame 43 and the base 1, and the protective cover 3 is tightly mounted on the base 1. At this time, the base 1 and the protective cover 3 are placed upside down in a vacuum coating chamber to perform vacuum coating on the bottom end of the corner cube prism. When coating the upper end surface of the corner cube prism, the blocking block 45 is stuck at the bottom end of the base 1. Through the magnetic ring 411 and the iron ring 46, the blocking block 45 is positioned at the bottom end of the base 1 to block the opening at the bottom end of the base 1. At this time, the corner cube prism is placed into the fixture 2, and the inner side of the fixture 2 fits against the lower end surface of the corner cube prism. The bottom end of the corner cube prism is in contact with the top end of the blocking block 45, and the lower end surface of the corner cube prism is closely attached to the base 1. At this time, the base 1 is placed into the vacuum coating chamber to perform vacuum coating on the upper end surface of the corner cube prism.
