Description

Technical Field

[0001] The present invention belongs to the technical field of coating equipment, and in particular, it is a coating device for the production of security monitoring lenses. Background Technique

[0002] Security monitoring lenses are used in security prevention systems and are used in conjunction with cameras. They are the eyes in the security industry. Without these eyes, we cannot see the monitored targets. Their main function is to collect the reflected light of the photographed object and focus the reflected light on the CMOS sensor. The image projected onto the CMOS sensor is inverted, and the camera circuit has the function of inverting it. Its imaging principle is the same as that of the human eye. In order to obtain better imaging and improve the monitoring effect, security monitoring lenses usually need to be coated.

[0003] Currently, coating mainly refers to a type of coating that needs to be carried out under a relatively high vacuum. Specifically, it includes many types, including vacuum ion evaporation, magnetron sputtering, MBE molecular beam epitaxy, PLD laser sputtering deposition, etc. The main idea is divided into evaporation and sputtering. In some existing coating devices, the lens cannot rotate during coating, resulting in uneven coating. For example, (authorized announcement number CN211036088U) a lens coating device also has a similar problem. The lens is clamped and cannot rotate during coating, and the coating of the lens is not uniform. Therefore, a new type of coating device for the production of security monitoring lenses is needed. Summary of the Invention

[0004] The purpose of the present invention is to provide a coating device for the production of security monitoring lenses to solve the problems raised in the background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A coating device for the production of security monitoring lenses, including a box body. Four rotating shafts are symmetrically and fixedly installed on the box body, and the four rotating shafts are arranged at the two opposite side tops of the box body. Each rotating shaft is rotatably connected to a rotating seat. Four grooves adapted to the rotating shafts and the rotating seats are opened at the top of the box body. Each rotating seat is threadedly connected to a first screw rod. Each first screw rod is coaxially and fixedly sleeved with a limiting block. A top cover is installed on the top of the box body, and the limiting block is used to fix the top cover. Fixing grooves adapted to the rotating seat, the first screw rod, and the limiting block are opened on the top cover;

[0006] In the middle of the inner cavity side wall of the box body, a fixing frame is fixedly installed. A fixing clamping ring for clamping the security monitoring lens is rotatably installed on the fixing frame. On the inner cavity side wall of the box body opposite to the fixing frame, a rotating frame is rotatably installed. At one end of the rotating frame close to the fixing clamping ring, two sliding grooves are symmetrically opened, and a moving frame is slidably installed in the two sliding grooves together. An active clamping ring for clamping the security monitoring lens is welded on the moving frame, and the fixing clamping ring and the active clamping ring are adapted. The fixing clamping ring and the active clamping ring are both provided with grooves for clamping the security monitoring lens.

[0007] Preferably, at the top of each first screw rod, a first turntable convenient for rotation is coaxially fixedly connected, and the limiting blocks are all clamped at the top of the fixing grooves.

[0008] Preferably, a sealing groove for improving the sealing performance of the box body is opened on the box body, and a rubber pad adapted to the sealing groove is adhesively bonded to the lower surface of the top cover.

[0009] Preferably, at one end of the fixing frame close to the fixing clamping ring, a rotating motor with an output end is fixedly installed, and the output end of the rotating motor is coaxially fixedly connected to the central axis of the fixing clamping ring.

[0010] Preferably, the rotating frame is rotatably installed with a second screw rod through a bearing, and the second screw rod is coaxially fixedly connected to the inner ring of the bearing. The second screw rod is threadedly connected to the moving frame.

[0011] Preferably, at the end of the second screw rod away from the moving frame, a second turntable is coaxially fixedly connected, and a through groove convenient for the rotation of the second turntable is opened on the rotating frame.

[0012] Preferably, at one end of the moving frame close to the second turntable, a threaded hole adapted to the second screw rod is opened.

[0013] Preferably, an evaporation pool for coating is installed on the top surface of the box body, and a heater for coating is welded on the lower surface of the top cover.

[0014] Preferably, a vacuum pump is fixedly installed on the outer side wall of the box body, and a through hole adapted to the vacuum pump is opened on the box body.

[0015] Compared with the prior art, the technical effects and advantages of the present invention are as follows:

[0016] When the coating device for producing the security monitoring lens is in use, cover the top cover, rotate the rotating seat to the vertical position, and then rotate the first turntable, so that the first screw rod drives the limiting blocks to move vertically downward. The limiting blocks are all clamped at the top of the fixing grooves. Most of the volume of the limiting blocks can be accommodated at the top of the fixing grooves, and the limiting blocks will not slide out. Finally, the top cover presses the box body tightly, improving the sealing performance of the box body.

[0017] When the coating device for producing security monitoring lenses is in use, place the lens between the fixed clamping ring and the movable clamping ring. Rotate the second turntable so that the second screw drives the movable clamping ring and the fixed clamping ring to jointly clamp the lens through the moving frame. Then start the rotating motor to drive the fixed clamping ring, the movable clamping ring, the lens and related structures to rotate slowly together, which is convenient for uniformly coating the lens. The rotating direction of the rotating motor is opposite to the rotating direction of the second turntable before, so as to avoid the loosening of the lens clamping. The electrically rotating lens clamping ring is set, which improves the uniformity of the lens coating. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0030] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0031] In order to uniformly coat the security monitoring lens, as Figures 1 to 8 shown, a coating device for the production of security monitoring lenses is provided with an electrically rotating lens snap ring, which improves the uniformity of lens coating. Four rotating shafts 2 are symmetrically and fixedly installed on the box body 1, and the four rotating shafts 2 are arranged at the two opposite side tops of the box body 1. Each rotating shaft 2 is rotatably connected to a rotating seat 5. Four grooves adapted to the rotating shafts 2 and the rotating seats 5 are opened at the top of the box body 1. Each rotating seat 5 is threadedly connected to a first screw 6. Each first screw 6 is coaxially and fixedly sleeved with a limiting block 7. A top cover 9 is installed on the top of the box body 1, and the limiting block 7 is used to fix the top cover 9. Fixed grooves 11 adapted to the rotating seats 5, the first screws 6 and the limiting blocks 7 are opened on the top cover 9. The top of each first screw 6 is coaxially and fixedly connected with a first turntable 8 for easy rotation, and the limiting blocks 7 are all clamped at the top of the fixed grooves 11. The top of the fixed grooves 11 can accommodate most of the volume of the limiting blocks 7, and the limiting blocks 7 will not slide out. Finally, the top cover 9 presses the box body 1 to improve the sealing performance of the box body 1.

[0032] In the middle of the inner cavity side wall of the box body 1, a fixing frame 12 is fixedly installed. A fixing clamping ring 14 for clamping the security monitoring lens is rotatably installed on the fixing frame 12. At one end of the fixing frame 12 close to the fixing clamping ring 14, a rotating motor 13 with an output end is fixedly installed, and the output end of the rotating motor 13 is coaxially and fixedly connected to the central axis of the fixing clamping ring 14. The rotating motor 13 is a prior art and has nothing to do with the innovation of this case, so it will not be elaborated here. On the inner cavity side wall of the box body 1 opposite to the fixing frame 12, a rotating frame 15 is rotatably installed. At one end of the rotating frame 15 close to the fixing clamping ring 14, two sliding grooves are symmetrically opened, and a moving frame 16 is slidably installed in these two sliding grooves together. An active clamping ring 17 for clamping the security monitoring lens is welded on the moving frame 16, and the fixing clamping ring 14 and the active clamping ring 17 are adapted. Both the fixing clamping ring 14 and the active clamping ring 17 are provided with grooves for clamping the security monitoring lens. The rotating frame 15 is rotatably installed with a second screw rod 18 through a bearing, and the second screw rod 18 is coaxially and fixedly connected to the inner ring of the bearing. The second screw rod 18 is threadedly connected to the moving frame 16. One end of the second screw rod 18 far from the moving frame 16 is coaxially and fixedly connected to a second turntable 19. The rotating frame 15 is provided with a through groove for facilitating the rotation of the second turntable 19. One end of the moving frame 16 close to the second turntable 19 is provided with a threaded hole adapted to the second screw rod 18. When in use, place the lens between the fixing clamping ring 14 and the active clamping ring 17, rotate the second turntable 19, so that the second screw rod 18 drives the active clamping ring 17 and the fixing clamping ring 14 to jointly clamp the lens through the moving frame 16, and then start the rotating motor 13 to drive the fixing clamping ring 14, the active clamping ring 17, the lens and related structures to rotate at a low speed together, which is convenient for uniformly coating the lens. The rotating direction of the rotating motor 13 is opposite to the rotating direction of the second turntable 19 before, so as to avoid the loosening of the lens clamping.

[0033] On the top surface of the box body 1, an evaporation pool 20 for coating is installed. On the lower surface of the top cover 9, a heater 21 for coating is welded. The evaporation pool 20 and the heater 21 are used for coating the lens. On the outer side wall of the box body 1, a vacuum pump 22 is fixedly installed, and a through hole 4 adapted to the vacuum pump 22 is opened on the box body 1. The vacuum pump 22 is a prior art and has nothing to do with the innovation of this case, so it will not be elaborated here. The vacuum pump 22 is used to evacuate the box body 1 to provide a vacuum coating environment.

[0034] Working principle

[0035] For the coating device used in the production of the security monitoring lens, when in use, place the lens between the fixed clamping ring 14 and the movable clamping ring 17, rotate the second turntable 19, so that the second screw rod 18 drives the movable clamping ring 17 and the fixed clamping ring 14 through the moving frame 16 to jointly clamp the lens. Then start the rotating motor 13 to drive the fixed clamping ring 14, the movable clamping ring 17, the lens and related structures to rotate at a low speed together, which is convenient for uniformly coating the lens. The rotating direction of the rotating motor 13 is opposite to the rotating direction of the second turntable 19 before, to avoid the loosening of the lens clamping. Cover the top cover 9, rotate the rotating seat 5 to the vertical position, and then rotate the first turntable 8, so that the first screw rod 6 drives the limiting block 7 to move vertically downward. The limiting blocks 7 are all clamped at the top of the fixed groove 11. Most of the volume of the limiting block 7 can be accommodated at the top of the fixed groove 11, and the limiting block 7 will not slide out, so that the top cover 9 presses the box body 1, improving the sealing performance of the box body 1. Then, the box body 1 will be evacuated by the vacuum pump 22, and then the lens will be coated through the evaporation pool 20 and the heater 21.
