Embodiment 1

[0036] like figure 1 Shown, a kind of expanding film machine comprises:

[0037] A working platform, on which there is an expanding film base that can be raised and lowered relative to the working platform; specifically, the expanding film base is connected with a lifting mechanism such as a cylinder;

[0038] Cover body, the cover body is opened and closed relative to the film expansion base, the cover body includes a cover body and a sub-cover body, the cover body has a through hole opened relative to the film expansion base, the sub-cover body is arranged relative to the film expansion base, and the sub-cover body can Pass through the through hole to contact with the expansion film base; specifically, a number of guide columns are arranged between the sub-cover body and the cover body along the circumferential direction, and the sub-cover body is connected with a power device, which is a lifting cylinder in this embodiment.

[0039] The sub ring and the mother ring, the su...

Embodiment 2

[0044] The process of cutting by using the film expander in embodiment 1, wherein, in order to match the shape of the processing component, the film expander base, the through hole and the sub-cover are all circular. The process includes steps:

[0045] (1) Attach four middle pieces in the middle of the front of the film, and the number of middle pieces can be adjusted arbitrarily according to needs. Then attach the first wafer ring to the front of the film along the periphery of the film to form a sheet component;

[0046] (2) Put the sheet assembly into the laser cutting machine, and then use the laser beam to cut the middle sheet into several small pieces; specifically, rectangular small pieces of uniform size; such as figure 2 as shown,

[0047] (3) Take out the sheet assembly and put it into the expansion machine to expand the film, such as image 3 Shown:

[0048] (3-1) Place the sub-ring on the expansion film base, place the mother ring on the sub-cover, then heat ...

Abstract

The invention discloses a film expansion machine and a process for laser cutting by employing same. The film expansion machine comprises a working platform, a cover body, a son ring and a mother ring, wherein a film expansion base is arranged on the working platform and can lift relative to the working platform, the cover body is opened and closed relative to the film expansion base and comprises a cover body and a sub-cover body, the cover body is provided with a through hole opened relative to the film expansion base, the sub-cover body is arranged relative to the film expansion base, the sub-cover body can penetrate through the through hole to be in contact with the film expansion base, the son ring is arranged on the film expansion base, the mother ring is arranged on the sub-cover body, and the son ring and the mother ring can be buckled together during contact. During cutting, a sheet assembly is formed from an intermediate sheet by a lamination film, and cutting and film expansion are sequentially performed. The film expansion machine has the advantages of high film expansion efficiency, good film expansion quality and simple structure, and is convenient to use. The cutting process is reasonable in step, and compared with the prior art, the cutting efficiency and the cutting quality are both improved.

Description

technical field [0001] The invention relates to the processing of optical filters and other components in the field of photoelectric technology, in particular to a film expander and a laser cutting process using the film expander. Background technique [0002] Traditional color filters or optical filters and other components are cut with DISCO mounted diamond blades. Since these components are brittle materials, they are easily broken. Contact processing can easily lead to cracks at the edge of the color filter, and the intersection is more serious, resulting in filter failure. There are a lot of edge chipping of the color chip, and sometimes hidden cracks are caused, which leads to unstable bonding force of the finished product. The new type of laser cutting belongs to non-contact processing, no stress, straight and tidy cutting edge, no damage; there is no problem of prop wear and tear, and the structure of the color filter will not be damaged; the cutting speed is fast, a...
