Problems solved by technology

[0005] In view of the above deficiencies in the prior art, the purpose of the present invention is to provide a line-scanning light module for developing glass and a liquid crystal full-film image detection machine to solve the problem of the light source provided by the line-sweeping light module in the prior art. After irradiating the developing glass, the imaging is not obvious, which leads to the problem of poor detection effect

Embodiment 1

[0041] Such as figure 1 , figure 2 As shown, this embodiment discloses a line-scanning light module 10 for developing glass, which is used to detect lines on the developing glass, which includes a light source part 100, a light guide part 200, and a light-shielding sheet (not marked in the figure) ). For the convenience of structural description, take the projected outline of the line-sweeping optical module 10 on the horizontal plane as a rectangle as an example, the long side direction of the rectangle is the length direction, and the short side direction is the width direction. In this embodiment, both the length direction and the width direction are used As a benchmark, the structural description is carried out. The light source part 100 in this embodiment is extended along the longitudinal direction, and the light source part 100 includes a plurality of light guide round tables 210, and the plurality of light guide round tables 210 are arranged corresponding to the plu...

Embodiment 2

[0057] Such as image 3 , Figure 4 As shown, based on the same idea, the present invention also proposes a liquid crystal full-film image inspection machine, which includes: a machine platform 20, an XYZ direction moving assembly 30, a camera assembly 40, and the line-scanning optical module in Embodiment 1 10. The machine table 20 is arranged horizontally, the XYZ direction moving assembly 30 is arranged on the machine table 20, the camera assembly 40 is arranged on the XYZ direction moving assembly 30; the line scanning optical module 10 is detachable It is arranged on the moving component 30 in the XYZ direction. The developing glass to be inspected is placed horizontally on the machine platform 20, and the camera assembly 40 and the line scanning module are moved in the X direction, the Y direction, and the Z direction through the XYZ direction moving assembly 30 to realize the camera assembly 40 and the line scanning module. The module scans the developing glass to be...

Abstract

The linear light sweeping module is used for detecting a developing line on the developing glass, the linear light sweeping module comprises a light source part, the light source part comprises a plurality of light-emitting parts arranged side by side in the length direction, and the light-emitting parts emit white light; the light guide part comprises a plurality of light guide circular truncated cones, and the light guide circular truncated cones correspond to the light emitting pieces in the axial direction and are located on the light emitting sides of the light emitting pieces; and the anti-dazzling screens are arranged at the two ends of the light guide part in the length direction. The problem that in the prior art, after a light source provided by a linear light sweeping module irradiates developing glass, imaging is not obvious, and the detection effect is poor is solved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal screen manufacturing, in particular to a line-scanning light module used for developing glass and a liquid crystal full-film image detection machine. Background technique [0002] In the production process of LCD screens, especially in the manufacture of black and white LCD screens, the transparent glass of the entire film forms a developing glass after the development process is completed, and a developing circuit is formed on the glass. The developing circuit can then be etched to form the required circuit. The development circuit may be poorly etched due to foreign objects, scratches, etc. For this kind of defect, it is usually manually inspected by a high-powered microscope to check the outline of the circuit on the developing glass to ensure that the first sample is a good product before it is mass-produced on the assembly line. However, the efficiency of manual inspection is low, an...
