Description
Technical Field
[0001] This utility model relates to the technical field of lens coating devices, and specifically to an optical lens coating device. Background Technology
[0002] A lens is an optical element made of a transparent material with a spherical surface. A lens consists of several lens elements and comes in two main types: plastic and glass. Lenses are widely used in security, automotive, digital cameras, lasers, optical instruments, and many other fields. With continuous market development, lens technology is becoming increasingly widely applied. Generally, lenses have poor wear resistance and corrosion resistance, and long-term use can easily lead to surface wear, deterioration, or breakage. Therefore, after lens molding, surface coating treatment is usually required. Depending on the needs, antistatic films, wear-resistant films, anti-reflective films, broadband multilayer films, narrowband multilayer films, beam-splitting films, filter films, and reflective films can be applied to the lens surface to enhance light transmission and improve lens wear resistance.
[0003] A search revealed a utility model patent with publication number CN218984544U, which discloses an optical lens coating device. The device includes a housing and a lens body to be processed. The housing has an internal cavity, and two symmetrically arranged fixing members are located on the inner wall of the cavity. Two parallel elastic straps are positioned between the fixing members. Clamping plates are attached to the outer ends of both elastic straps. The upper ends of the clamping plates pass through a groove in the upper part of the housing and extend to the outer side of the housing. A double-ended lead screw is installed on the upper outer side of the housing, and sliders are threaded onto both ends of the double-ended lead screw. The sliders are fixedly connected to the upper ends of the clamping plates. The advantages of this utility model are: by rotating the handwheel at one end of the double-ended lead screw, the lens body can be effectively clamped and fixed by the clamping plates and elastic straps, making it convenient and quick to use. Furthermore, the screw does not come into contact with the surface of the lens body during the entire process, ensuring the cleanliness of the lens body surface.
[0004] While the aforementioned patent effectively clamps and fixes the lens body using clamps and elastic straps, making it convenient and quick to use, and ensuring the cleanliness of the lens body surface by avoiding contact with it throughout the process, the device, although capable of clamping and fixing lenses of different diameters, requires coating operations on both sides and the sides of the lens during coating. However, clamping and fixing the lens body using clamps and elastic straps can easily loosen during flipping, leading to the risk of the lens falling off during the flipping process. Furthermore, it cannot coat the sides of the lens, affecting the efficiency of lens coating.
[0005] Therefore, it is necessary to propose an optical lens coating device to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide an optical lens coating device. Through the cooperation of the internal parts of the clamping mechanism, the lens can be clamped and fixed, and the limitation on the telescopic column can be released, allowing the clamping plate to rotate via the telescopic column. This causes the lens clamped and fixed by the clamping plate to rotate, thereby completing double-sided coating of the lens. Through the cooperation of the internal parts of the rotating mechanism, the lens can be rotated inside the clamping plate to complete the coating operation on the side of the lens. This solves the problem in the prior art where the lens requires coating on both sides and the side, and the clamping and fixing of the lens body using clamping plates and elastic straps is prone to loosening during flipping, leading to the risk of the lens falling off during the flipping process. Furthermore, it prevents coating on the side of the lens, affecting the lens coating efficiency.
[0007] To achieve the above objectives, the present invention provides the following technical solution: an optical lens coating device, comprising a device body, an electric tray fixedly mounted on the top of the device body, a clamping mechanism bolted to one side of the device body and extending through the interior of the device body and slidably connected to both sides of the electric tray, and a rotating mechanism rotatably connected to the top of the clamping mechanism and extending through the clamping mechanism to the inner wall of the clamping mechanism.
[0008] The clamping mechanism includes a fixed base, which is distributed on both sides of the electric tray. A clamping plate is connected to the side of the fixed base closer to the electric tray. A telescopic column is mechanically connected between the clamping plate and the fixed base and slides through the interior of the fixed base. Limit blocks are mechanically machined at the top and bottom of the outer wall of the telescopic column and are slidably connected to the inner wall of the fixed base. A telescopic spring is mechanically connected between the telescopic column and the inner wall of the fixed base.
[0009] The rotating mechanism includes a knob rotatably connected to the top of the clamping plate and extending into the interior of the clamping plate. The bottom end of the knob is mechanically connected to a transmission gear. The interior of the clamping plate is rotatably connected to a connecting shaft located on one side of the transmission gear. The outer wall of the connecting shaft is mechanically connected to a connecting gear. The bottom end of the connecting shaft is rotatably connected to a transmission shaft and extends into one side of the inner wall of the clamping plate. The interior of the clamping plate is mechanically connected to arc-shaped buffer plates located at both ends of the transmission shaft.
[0010] Preferably, the clamping mechanism further includes a servo motor, which is bolted to one side of the device body. The output end of the servo motor is mechanically connected to a threaded rod that extends into the interior of the device body. A sliding bracket is slidably sleeved on the outer wall of the threaded rod and distributed on both sides of the electric tray. The top end of the sliding bracket is connected and fixed to the bottom end of the fixed base.
[0011] Preferably, the outer wall of the threaded rod is machined with symmetrically distributed external threads, and the inner wall of the multiple sliding brackets is provided with internal threads that match the symmetrical threads on the outer wall of the threaded rod. The top of the main body of the device is provided with a sliding groove that matches the sliding bracket.
[0012] Preferably, the fixed base has an internal telescopic groove that matches the telescopic column and a limiting groove that matches the limiting block. The inner wall of the fixed base is mechanically connected with an elastic locking block, and the outer wall of the telescopic column is machined with a groove that matches the elastic locking block, and the grooves are symmetrically distributed at 180 degrees.
[0013] Preferably, the knob and connecting shaft are rotatably connected to the clamping plate via bearings, the transmission gear and the connecting gear mesh with each other via tooth grooves, and the clamping plate has a transmission groove inside that matches the transmission gear and the connecting gear.
[0014] Preferably, the arc-shaped buffer sheet is made of flexible sponge, and the outer wall of the drive shaft is mechanically connected with flexible rubber strips, which are densely distributed on the outer wall of the drive shaft.
[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0016] 1. By placing the lens on the electric tray and starting the servo motor, the servo motor drives the threaded rod to rotate. The rotation of the threaded rod causes the sliding bracket to move, bringing the sliding bracket closer to the electric tray. The movement of the sliding bracket, through the fixed seat, causes the clamping plate to move and fit against the lens on the electric tray, thus completing the clamping and fixing of the lens. At the same time, the fixed seat causes the clamping plate to continue to fit against each other, causing the telescopic column to be compressed and the telescopic spring to contract and move. The movement of the telescopic column causes the limiting block to move, allowing the limiting block to slide out of the limiting groove, releasing the rotation limit of the telescopic column inside the fixed seat. Then, the operator can rotate the telescopic column to rotate the clamping plate, thus completing the flipping of the lens and completing the double-sided coating operation of the lens.
[0017] 2. By rotating the knob, the transmission gear rotates. The transmission gear and the connecting gear mesh with each other through the tooth grooves. The rotation of the transmission gear drives the connecting gear to rotate, which in turn drives the connecting shaft to rotate. This, in turn, drives the transmission shaft at the bottom of the connecting shaft to rotate. Flexible rubber strips are mechanically connected to the outer wall of the transmission shaft and are densely distributed on the outer wall. This facilitates the rotation of the transmission shaft. The flexible rubber strips on the outer wall rub against the lens, causing the lens to rotate on the inner wall of the clamping plate. The curved buffer sheet is made of flexible sponge. When the lens rotates on the inner wall of the clamping plate, the curved buffer sheet protects the side wall of the lens from direct contact with the clamping plate, thus avoiding scratches caused by direct contact between the side wall of the lens and the clamping plate. This completes the rotation of the lens on the inner wall of the clamping plate, thereby completing the coating operation on the side wall of the lens. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0026] This utility model provides, for example Figure 1-4 An optical lens coating device is shown, including a device body 1. An electric tray 101 is fixedly mounted on the top of the device body 1. A clamping mechanism 2 is bolted to one side of the device body 1 and extends into the interior of the device body 1 and is slidably connected to both sides of the electric tray 101. A rotating mechanism 3 is rotatably connected to the top of the clamping mechanism 2 and extends through the clamping mechanism 2 to the inner wall of the clamping mechanism 2.
[0027] The clamping mechanism 2 includes a fixed base 204, which is distributed on both sides of the electric tray 101. A clamping plate 205 is connected to the side of the fixed base 204 closest to the electric tray 101. A telescopic column 206 is mechanically connected between the clamping plate 205 and the fixed base 204 and slides through the fixed base 204. Limiting blocks 207 are mechanically machined at the top and bottom of the outer wall of the telescopic column 206 and slides through the inner wall of the fixed base 204. A telescopic spring 208 is mechanically connected between the telescopic column 206 and the inner wall of the fixed base 204.
[0028] The rotating mechanism 3 includes a knob 301, which is rotatably connected to the top of the clamping plate 205 and extends into the interior of the clamping plate 205. The bottom end of the knob 301 is mechanically connected to a transmission gear 302. The interior of the clamping plate 205 is rotatably connected to a connecting shaft 303, which is located on one side of the transmission gear 302. The outer wall of the connecting shaft 303 is mechanically connected to a connecting gear 304. The bottom end of the connecting shaft 303 is rotatably connected to a transmission shaft 305, which extends into one side of the inner wall of the clamping plate 205. The interior of the clamping plate 205 is mechanically connected to an arc-shaped buffer plate 306, which is located at both ends of the transmission shaft 305.
[0029] By cooperating with each other among the internal parts of the clamping mechanism 2, the lens can be clamped and fixed, and the limitation on the telescopic column 206 can be released, so that the clamping plate 205 can be rotated by the telescopic column 206, and the lens clamped and fixed by the clamping plate 205 can be rotated 180 degrees, thereby completing the double-sided coating of the lens. By cooperating with each other among the internal parts of the rotating mechanism 3, the lens can be rotated inside the clamping plate 205 to complete the coating operation on the side of the lens.
[0030] Refer to the instruction manual appendix Figure 1-4 The clamping mechanism 2 also includes a servo motor 201, which is bolted to one side of the main body 1 of the device. The output end of the servo motor 201 is mechanically connected to a threaded rod 202, which extends into the interior of the main body 1 of the device. A sliding bracket 203 is slidably sleeved on the outer wall of the threaded rod 202 and distributed on both sides of the electric tray 101. The top of the sliding bracket 203 is connected and fixed to the bottom of the fixed seat 204. Through the mutual cooperation between the internal parts of the clamping mechanism 2, the sliding bracket 203 and the electric tray 101 can be driven to move closer to each other, so that the clamping plate 205 can complete the clamping and fixing of the lens on the electric tray 101.
[0031] Refer to the instruction manual appendix Figure 1-4The outer wall of the threaded rod 202 is machined with symmetrically distributed external threads, and the inner walls of multiple sliding supports 203 are provided with internal threads that match the symmetrical threads on the outer wall of the threaded rod 202. The top of the device body 1 is provided with a sliding groove that matches the sliding support 203. The symmetrically distributed external threads on the outer wall of the threaded rod 202 and the internal threads that match the symmetrical threads on the inner walls of multiple sliding supports 203 facilitate the rotation of the threaded rod 202 to drive the sliding support 203 to slide at the top of the device body 1.
[0032] Refer to the instruction manual appendix Figure 1-4 The fixed base 204 has an internal telescopic groove that matches the telescopic column 206 and a limiting groove that matches the limiting block 207. The inner wall of the fixed base 204 is mechanically connected with an elastic locking block, and the outer wall of the telescopic column 206 is machined with a groove that matches the elastic locking block, which are symmetrically distributed at 180 degrees. The internal telescopic groove of the fixed base 204 that matches the telescopic column 206 and the limiting groove that matches the limiting block 207 facilitate the limiting block 207 to slide out of the limiting groove, thereby releasing the rotational limitation of the telescopic column 206 inside the fixed base 204.
[0033] Refer to the instruction manual appendix Figure 1-4 The knob 301 and connecting shaft 303 are rotatably connected to the clamping plate 205 via bearings. The transmission gear 302 and the connecting gear 304 mesh with each other through tooth grooves. The clamping plate 205 has transmission grooves inside that match the transmission gear 302 and the connecting gear 304. The transmission grooves inside the clamping plate 205 facilitate the rotation of the transmission gear 302 to drive the connecting gear 304 to rotate.
[0034] Refer to the instruction manual appendix Figure 1-4 The arc-shaped buffer 306 is made of flexible sponge. Flexible rubber strips are mechanically connected to the outer wall of the drive shaft 305 and are densely distributed on the outer wall of the drive shaft 305. The flexible sponge material of the arc-shaped buffer 306 and the flexible rubber strips mechanically connected to the outer wall of the drive shaft 305 facilitate the rotation of the drive shaft 305. The flexible rubber strips on the outer wall rub against the lens, causing the lens to rotate on the inner wall of the clamping plate 205.
[0035] The working principle of this practical application is as follows:
[0036] Refer to the instruction manual appendix Figure 1-4By placing the lens on the electric tray 101 and starting the servo motor 201, the servo motor 201 drives the threaded rod 202 to rotate. The rotation of the threaded rod 202 causes the sliding bracket 203 to move, bringing the sliding bracket 203 closer to the electric tray 101. The movement of the sliding bracket 203, through the fixed seat 204, causes the clamping plate 205 to move and fit against the lens on the electric tray 101, thus completing the clamping and fixing of the lens. At the same time, the fixed seat 204 causes the clamping plate 205 to continue to fit against each other, causing the telescopic column 206 to be compressed and the telescopic spring 208 to contract and move. The movement of the telescopic column 206 causes the limiting block 207 to move, allowing the limiting block 207 to slide out of the limiting groove, releasing the rotation limit of the telescopic column 206 inside the fixed seat 204. Then, the operator can rotate the telescopic column 206 to rotate the clamping plate 205, thus completing the flipping of the lens and completing the double-sided coating operation of the lens.
[0037] Refer to the instruction manual appendix Figure 1-4 By rotating knob 301, the rotation of knob 301 drives the transmission gear 302 to rotate. The transmission gear 302 and the connecting gear 304 mesh with each other through tooth grooves. The rotation of transmission gear 302 drives the rotation of connecting gear 304, which in turn drives the connecting shaft 303 to rotate. This, in turn, drives the transmission shaft 305 at the bottom of the connecting shaft 303 to rotate. Flexible rubber strips are mechanically connected to the outer wall of the transmission shaft 305 and are densely distributed on the outer wall of the transmission shaft 305. The rotation of the transmission shaft 305 is facilitated by friction between the flexible rubber strips on the outer wall and the lens, causing the lens to rotate on the inner wall of the clamping plate 205. The arc-shaped buffer sheet 306 is made of flexible sponge. When the lens rotates on the inner wall of the clamping plate 205, the arc-shaped buffer sheet 306 protects the side wall of the lens from direct contact with the inner wall of the clamping plate 205, thus avoiding scratches caused by direct contact between the side wall of the lens and the clamping plate 205. This completes the rotation of the lens on the inner wall of the clamping plate 205, thereby completing the coating operation on the side wall of the lens.
[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
