Description

Technical Field

[0001] The utility model relates to the technical field of optical film clamps, in particular to an adjustable clamp for optical films. Background Art

[0002] Optical thin films are a type of optical dielectric material composed of thin layered media that propagate light beams through interfaces. They are widely used in the fields of optics and optoelectronics. In modern science and technology, optical thin films are widely used, such as in the manufacture of various optical instruments, improving the luminous flux of optical lenses, enhancing the output power of lasers, and improving the efficiency and stability of silicon photovoltaic cells.

[0003] When in use, existing coating equipment usually clamps and fixes one side wall of the lens and then coats the other side of the lens. For example, Chinese patent publication No. "CN217973385U" discloses an adjustable optical coating fixture, which includes a workbench, and two groups of relatively distributed vertical plates are fixedly installed on the surface of the workbench. The two side walls of the two groups of relatively distributed vertical plates are rotatably connected to a placement rack. The placement rack is an inverted U-shaped structure, and one side wall of the placement rack is fixedly connected to a rotating rod. The end of the rotating rod away from the placement rack is fixedly connected to a control panel, and the bottom wall of the placement rack is provided with two groups of relatively distributed sliding plates.

[0004] When the optical thin film fixture currently used is clamped, if the length, width, and thickness of the substrate to be coated changes, the fixture needs to be redesigned and processed, which not only wastes time but also increases the cost of coating and causes unnecessary waste.

[0008] Furthermore, the clamping assembly includes a screw rotatably connected to the inner walls of at least three T-slots and a transmission bevel gear rotatably connected to the bottom end of the circular groove. Fixed bevel gears are fixed on the inner side of the screw, and the transmission bevel gears are meshed with the fixed bevel gears respectively. The surface of the screw is threadedly connected to a movable seat, and the top of the movable seat extends to the outside of the T-slot and is provided with a lifting mechanism.

[0009] Furthermore, the lifting mechanism includes a sliding groove opened on the surface of the movable seat, and the inner side of the sliding groove is slidably connected to the clamping seat, the bottom end of the sliding groove is rotatably connected to a threaded column, and the threaded column is threadedly connected to the clamping seat, and the top of the threaded column passes through the sliding groove and is fixed with a knob.

[0010] Furthermore, the clamping seat is an L-shaped plate, and an arc-shaped groove for laminating the film substrate is opened on the inner side of the clamping seat.

[0011] Furthermore, the clamping mechanism includes several bosses fixed to the top of the triangular frame and guide grooves opened on the surface of the bosses. The inner side of the guide groove is slidably connected with a clamping block, and a telescopic rod is provided between the clamping block and the guide groove. A spring is provided on the surface of the telescopic rod, and the two ends of the spring respectively conflict with the clamping block and the guide groove, and the clamping block is clamped with the edge position of the movable cover.

[0013] The adjustable clamp for optical film proposed by the utility model has the beneficial effects that: the utility model can drive the movable seat to clamp the film substrate by rotating one of the screws through the fixed bevel gear and the transmission bevel gear. The liftable clamping seat on the movable seat can adjust the clamping height of the film substrate. The movable cover can be easily opened through the clamping block to facilitate cleaning and maintenance of the screw and the interior of the clamp. It is not only convenient and quick to use, but also can reduce the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS
