Description

Optical lens piece coating film anchor clamps convenient to get piece

Technical Field

The utility model relates to an optics coating film instrument field, concretely relates to optics lens piece coating film anchor clamps convenient to get piece.

Background

When light enters the glass from air, about 5% of the light is reflected, and a plurality of lenses and refractors are arranged in optical equipment such as an optical telescope, a magnifying glass, a photographic lens and the like, so that the total loss of the incident light can reach 30-40%. Modern optical lenses usually adopt a coating process to reduce the reflection amount of light, and usually adopt a single-layer or multi-layer fluoride antireflection film, the reflection can be reduced to 1.5% by the single-layer antireflection film, the reflection can be reduced to 0.25% by the multi-layer antireflection film, and the light transmittance is greatly improved by coating.

Generally, the lens is clamped by a clamp in an ionized steam environment, and the film is coated by a thin film deposition method. After coating, a lens clamped on the clamp needs to be taken down by one piece, and because the lens is clamped in the clamp, the coated lens is easily worn in the taking process.

SUMMERY OF THE UTILITY MODEL

The utility model provides an optical lens piece coating film anchor clamps convenient to get piece.

In order to achieve the above object, the utility model adopts the following technical scheme:

the optical lens coating clamp convenient for taking the lens comprises a first clamp body and a second clamp body;

the first fixture body and the second fixture body are combined together in a superposed mode, and a plurality of first coating holes are formed in the first fixture body;

the second fixture body is provided with a plurality of second coating holes which are opposite to the first coating holes, and the second coating holes are provided with annular dislocation platforms; the second fixture body is also provided with a plurality of positioning columns matched with the first fixture body;

the second fixture body is movably connected with a plurality of sheet taking frames through connecting columns, and the sheet taking frames are embedded in the second fixture body.

Furthermore, a plurality of sheet taking frames corresponding to the second film coating holes are arranged on the sheet taking frame, and a plurality of sheet taking hooks are symmetrically distributed in the sheet taking frames.

Furthermore, the film taking hook is in a staggered platform shape and is embedded in the second film coating hole and the annular staggered platform.

Furthermore, the positioning column is a triangular prism arranged on the vertex angle of the second clamp body.

The utility model has the advantages that:

1. an entire row of lenses clamped in the second fixture body can be directly taken out through the lens taking frame, so that the lens taking efficiency is high;

2. because the piece frame of getting is frame construction, after taking out the lens from second coating film hole, the lens has great space all around, for the state of card in second coating film hole, the lens in getting the piece frame is changeed in taking, has avoided being scraped the flower at the in-process lens of taking.

Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes may be made apparent to those skilled in the art within the spirit and scope of the present invention as defined and defined by the appended claims.

Example 1

As shown in fig. 1, 2 and 3, the optical lens coating fixture for facilitating taking a lens includes a first fixture body 1 and a second fixture body 2. The first fixture body 1 and the second fixture body 2 are overlapped and combined together, and a plurality of first coating holes 101 are formed in the first fixture body 1. The second fixture body 2 is provided with a plurality of second coating holes 202 opposite to the first coating holes 101, and the lens 3 is fixedly clamped between the first coating holes 101 and the second coating holes 202 by the first fixture body 1 and the second fixture body 2.

An annular dislocation 207 is arranged on the second coating hole 202, the lens 3 is clamped in the second coating hole 202 to prevent transverse displacement, and the annular dislocation 207 limits the axial displacement of the lens 3. The second fixture body 2 is also provided with a plurality of positioning columns 201 matched with the first fixture body 1, so that the first fixture body 1 and the second fixture body 2 are prevented from generating relative displacement on a joint surface to scrape the patterned lens 3.

The second fixture body 2 is movably connected with a plurality of sheet taking frames 203 through connecting columns 205, the sheet taking frames 203 are embedded in the second fixture body 2, and the top plane of the sheet taking frames 203 is lower than the combination surface of the first fixture body 1 and the second fixture body 2, so that the first fixture body 1 and the second fixture body 2 are tightly combined. In use, one end of the rack 203 is lifted and the other end is rotated about the connecting post 205. When the pick frame 203 is lifted, the pick frame 203 takes out the lens 3 inserted into the second coating hole 202.

Example 2

In this embodiment, the film taking frame 203 is provided with a plurality of film taking frames 204 corresponding to the second film coating holes 202, and a plurality of film taking hooks 206 are symmetrically distributed in the film taking frames 204. The film taking hook 206 is in a staggered form and is embedded in the second film coating hole 202 and the annular staggered platform 207.

When the taking frame 203 is placed, the taking frame 203 is embedded in the second coating hole 202, and the placing of the lens 3 is not influenced.

When the taking frame 203 is lifted, the lens 3 embedded in the second coating hole 202 is taken out by the taking hook 206, and the lens does not slide relative to the taking hook 206, so that the lens 3 is prevented from being scratched.

Example 3

The positioning columns 201 are triangular prisms arranged on the top corners of the second fixture body 2. The triangular prism shape has more force on the side surface and smaller cross-sectional area.
