Embodiment 1

[0060] See Figure 1~3 ,in, figure 2 yes figure 1 A partial enlarged view of a single wire grid unit in , image 3 It is a sectional view from direction A—A. It is an open wire grid splicing protection device, including a frame 1, multiple wire grid units 2, frame light blocking strips 3, seals 4 and an air circuit system. The wire grid units 2 are in a straight line Arranged on the frame 1, in this embodiment, fourteen wire grid units 2 are set, and the frame light blocking strip 3 is located below the splicing seam between the wire grid units 2 and is arranged on the wire grid units 2. On the frame 1, the frame light blocking strip 3 is not in contact with the wire grid unit 2, the width of the frame light blocking strip 3 is not less than the width of the splicing seam, and the sealing member 4 is arranged on the On the frame 1 and form an integral cavity 5 with the frame 1, the frame light-shielding strip 3 and the wire grid unit 2, the air circuit system is buried ins...

Embodiment 2

[0074] See Figure 6 ~ Figure 10 The difference between Embodiment 2 and Embodiment 1 is that one end of the wire grid unit 2 is positioned by the positioning pin 11 arranged on the frame 1 to position the first wire grid support 22 , and by The pressing nail 14 on the member 22 and the second wire grid support member 23 compresses the wire grid unit 2, thereby positioning the wire grid unit 2 on the frame 1, and the pressing nail 14 can fix the wire grid unit 2. The location of grid unit 2. In this embodiment, there are three pressing nails 14, and the center of the figure formed by the positioning pin 11 and the three pressing nails 14 coincides with the projection of the center of gravity of the wire grid 21 on the scale surface of the wire grid. . The second wire grid support member 23 is provided with a driving lever 15 corresponding to the position of the positioning pin 11 , and the wire grid 21 is rotatably adjusted in a plane through the driving rod 15 .

Abstract

The invention discloses a wire gating unit. The wire gating unit comprises a wire gating, a first wire gating support part, a second wire gating support part and wire gating pressing sheets; the wiregating is arranged on the first wire gating support part and the second wire gating support part which are arranged on the two sides of the opposite side of a wire grating scale surface respectively,the wire gating scale surface faces the first wire gating support part and the second wire gating support part, and the wire gating is fixed through the wire gating pressing sheets fixed to the firstwire gating support part and the second gating support part. The wire gating unit is simple in structure and wide in application range. The invention further discloses a protection device of the wiregating unit. The protection device adopts an assembly type structure, the effective light transmission area of the wire gating is increased, and the accumulated dose uniformity of the protection device in the whole machine is improved.

Description

technical field [0001] The invention relates to a wire grid unit and its protection device. Background technique [0002] The core component of the liquid crystal screen optical alignment equipment is the wire grid component part with the same polarization direction. Currently, it is limited by the manufacturing level of the wire grid. kind. At present, the production size of mainstream LCD screens in the world has reached 4.5G and 6G, so it is necessary to design a reliable wire grid splicing protection unit for the wire grid splicing protection device. [0003] The main performance requirements for the polarizer module of optical alignment equipment are generally: [0004] 1. Polarization angle error: ±870urad; [0005] 2. Extinction ratio: ≥100:1; [0006] 3. Combined lighting and other modules, the cumulative dose uniformity of light after passing through the wire grid: ≤5%. [0007] Among them, the cumulative dose uniformity in Article 3 is a comprehensive index of...
