Description

Technical Field

[0001] This utility model relates to the field of lens coating technology, specifically to an optical imaging lens coating fixture. Background Technology

[0002] Optical coating refers to the process of depositing one or more layers of metal or dielectric thin films on the surface of optical components. The purpose of coating the surface of optical components is to reduce or increase light reflection, beam splitting, color separation, filtering, polarization, etc. Optical lenses need to be coated to change the direction of light propagation and to change the relative spectral distribution of ultraviolet, visible, or infrared light. Optical lens coating can also improve the performance of the lens. By depositing different film layers on the surface of the lens, the lens can have higher hardness and wear resistance, thereby improving the quality of the lens. After the lens is formed, it needs to be coated. Existing coating fixtures are usually in the form of a spherical arc surface. The lens is placed by opening several through holes on the spherical arc surface. This method usually involves suspending the coating fixture on the evaporation source so that the coating molecules generated during the evaporation process can cover the lens during the rising process.

[0003] A Chinese patent with publication number CN221166717U discloses a lens coating clamp. In use, the device slides on a guide rail via a slide plate, which moves two clamping blocks so that the two first pads are respectively attached to the two sides of the lens, thereby fixing and clamping the lens. The knob can be rotated according to the curvature of the two sides of the lens to drive the brake gear to rotate, which in turn drives the driven gear to rotate, and finally drives the rotating clamp to rotate, so that the second pad is attached to the surface of the lens. A spring can tilt the second pad to a certain extent to cooperate with the support of the tray.

[0004] When the device is in operation, after the lens is coated with one layer of film, it needs to be manually opened to flip it over or transferred to another fixture to coat the other side. Conventional coating fixtures can only coat one side of the lens, that is, they can only fix the lens to face the same coating direction. Such a device is very expensive in terms of both manpower and mold consumption, which greatly reduces the practicality of the device. Utility Model Content

[0005] The purpose of this invention is to provide an optical imaging lens coating fixture. By using this device, the problem of having to manually open the device to flip the lens or transfer it to another fixture to coat the other side after coating is completed is solved. Conventional coating fixtures can only coat one side of the lens, that is, they can only fix the lens to face the same coating direction. Such devices have a great problem in terms of both labor consumption and mold consumption.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an optical imaging lens coating fixture, comprising a coating box, a protective cover installed at the upper end of the coating box, a sliding assembly installed inside the protective cover, a coating device fixedly installed at the lower end of the coating box, and a clamping device fixedly installed inside the coating box. The sliding assembly includes a pull rod, two sets of connecting blocks fixedly installed at one end of the pull rod, and a limit plate fixedly installed at the end of each of the two sets of connecting blocks away from the pull rod. A connecting rod is fixedly installed at the other end of the limit plate, and multiple sets of elastic elements are fixedly installed at the upper end of the connecting rod. The upper end of the elastic elements is fixedly connected to the inside of the protective cover, and the lower end of the connecting rod is fixedly installed with... The device includes a gear rod that matches the clamping device. An elastic element two is fixedly installed at the end of the gear rod and connecting rod away from the pulling rod. The other end of the elastic element two is fixedly connected to the inside of the protective cover. The protective cover has a sliding groove inside, which matches the connecting rod and the gear rod. When the lens needs to be coated, the lens is installed on the clamping device. The coating device then coats the lens. After a specified time, pulling the pulling rod causes the gear rod to engage and slide within the sliding groove and the clamping device. After the clamping device is flipped, the gear rod is reset by the action of elastic elements one and two, thus completing the coating on the other side of the lens on the clamping device.

[0007] Preferably, the coating box includes a protective shell, the inner side of which is fixedly connected to the clamping device. When it is necessary to coat the lens, the lens is placed on the clamping device by opening the protective cover, and the protective cover is closed so that the lens is coated inside the protective shell.

[0008] Preferably, a handle is fixedly installed on one side of the protective cover, and a slot is opened at one end of the pull rod away from the slide groove. Multiple sets of elastic elements are fixedly installed inside the slot. When it is necessary to coat the lens, the pull rod is pulled to make the gear rod slide in the slide groove, which drives the clamping device to rotate. After rotation, the elastic elements in the slot reset the device.

[0009] Preferably, the clamping device includes multiple sets of rotating gears. One end of the rotating gear is rotatably connected to the protective shell, and the other end of the rotating gear is fixedly mounted with a fixing rod. Multiple sets of clamping rings are fixedly mounted on the fixing rod. The rotating gear meshes with the gear rod. When it is necessary to coat the lens, the lens is placed inside the clamping ring for clamping. When it is necessary to flip the lens after clamping, the clamping ring rotates due to the meshing of the gear rod and the rotating gear, so that the other end of the lens faces the coating device for coating.

[0010] Preferably, multiple sets of curved springs are fixedly installed inside the clamping ring, and multiple sets of anti-slip balls are fixedly installed on the curved springs. An elastic element three is fixedly installed on the side of the curved springs near the clamping ring. The elastic element three is fixedly connected to the clamping ring. When the lens is placed inside the clamping ring for clamping, the lens is clamped by the inward squeezing of the curved springs, and the lens is protected against slippage by the anti-slip balls.

[0011] Preferably, the inner side of the clamping ring is provided with an annular groove, and two sets of sliding plates are fixedly installed on both sides of the curved spring. The sliding plates match the annular groove and are slidably connected to the annular groove. When the lens is placed inside the clamping ring for clamping, the curved spring bends inward, and the two ends of the inner curved spring slide in the annular groove through the sliding plates. When the lens is removed, the outer curved spring is squeezed and reset.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model proposes an optical imaging lens coating fixture. When we need to coat a lens, the lens is installed on the clamping device, and the coating device coats the lens. After a specified time, pressing the pull rod causes the gear rod to mesh with the clamping device. Pulling the pull rod causes the gear rod to slide on the clamping device. After the clamping device is flipped, the gear rod is reset by the action of elastic element one and elastic element two, thereby completing the coating of the other side of the lens on the clamping device.
