Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a tooling fixture for lens coating. Background Art

[0002] Reflection from lenses can reduce light transmittance and create interfering images on the retina, affecting image quality and the wearer's appearance. Examples include noticeable vortices on the lens' surface, backlighting, and the wearer's eyes being invisible. Coated lenses utilize new optical thin films and vacuum technology to coat them with a single or multilayer optical film of a certain thickness. This imparts new, previously unattainable properties, improving the lens's ability to reflect light, either enhancing or reducing light transmission, and increasing the lens's transmittance. The lens coating process requires securing the lens, necessitating the use of a lens coating fixture.

[0003] Chinese patent publication number CN219409887U discloses a lens coating fixture comprising two symmetrically arranged clamping mechanisms hingedly connected to each other. The clamping mechanism comprises a rectangular frame and multiple clamping plates embedded side by side within the frame. The rectangular frame's ends are removably connected to a sealing plate. Multiple semicircular notches are defined on either side of the clamping plates, with the semicircular notches on the sides of adjacent clamping plates forming a full circle. A retaining strip is provided on the inner side of each semicircular notch, which engages an annular retaining groove on the outer side of the lens. This utility model allows for direct lens installation and subsequent cleaning, drying, and coating processes, effectively saving manual assembly time and improving production efficiency.

[0004] While the lens coating fixture described above allows for direct lens installation and subsequent cleaning, drying, and coating, effectively saving manual assembly time, existing fixtures can only hold lenses of a single specification, and each lens in the fixture undergoes either a single or multiple-layer coating process. This makes it difficult to simultaneously coat lenses of multiple specifications. Therefore, we propose a lens coating fixture. Utility Model Content

[0005] The present invention aims to provide a lens coating fixture to solve the problem mentioned in the background art that existing fixtures can only hold lenses of a single specification, and each lens on the fixture is subjected to a single-layer or multi-layer coating process. Such fixtures are not convenient for coating lenses of multiple specifications at the same time.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a lens coating fixture, comprising:

[0007] A base, wherein a first clamping plate is mounted on the top of the base, and a plurality of first clamping holes are opened inside the first clamping plate, a second clamping plate is mounted on one side of the first clamping plate, and a second clamping hole and a third clamping hole are respectively provided in the second clamping plate;

[0008] A positioning plate is installed at both ends of the connection between the first clamping plate and the second clamping plate, and positioning bolts are installed on both sides of the positioning plate;

[0009] The lifting columns are respectively arranged inside the first clamping hole, the second clamping hole and the third clamping hole. A lifting plate is connected below the lifting columns, and a lifting push rod is installed below the lifting plate.

[0010] Preferably, the first clamping plate is connected to the second clamping plate through a positioning plate, and the positioning bolts pass through the interior of the positioning plate, and the positioning bolts are symmetrically distributed about the vertical center line of the positioning plate.

[0011] Preferably, the sizes of the first clamping hole, the second clamping hole and the third clamping hole increase in sequence, and the first clamping hole, the second clamping hole and the third clamping hole all correspond to the lifting columns one by one.

[0012] Preferably, the lifting column is further provided with:

[0013] A silica gel pad is connected to the upper end surface of the lifting column.

[0014] Preferably, the lifting push rod forms a telescopic structure between the lifting plate and the lifting column, and the lifting column and the lifting plate are perpendicular to each other.

[0015] Compared with the prior art, the present invention provides a lens coating fixture with the following features:

[0016] Beneficial effects:

[0017] The present invention facilitates the mutual connection and fixation of the first clamping plate and the second clamping plate by the cooperation of the positioning plate and the positioning bolt. The sizes of the first clamping hole, the second clamping hole and the third clamping hole are all different, so that lenses of different specifications can be clamped in a limited position, avoiding the problem that the existing clamp can only clamp lenses of a single specification. At the same time, the lenses on each clamp are simultaneously coated with a single layer or multiple layers. Such a clamp is not convenient for the simultaneous coating operation of lenses of multiple specifications. BRIEF DESCRIPTION OF THE DRAWINGS
