Problems solved by technology

[0002] There may be surface stains and processing burrs in the production process of the curved backplane. It is cost-intensive and inefficient to use artificial and human eyes for detection and processing, and the consistency of detection is not good. Therefore, the existing CCD industry can be used Visual cameras are used to replace human eyes to judge whether there are stains or burrs on the surface; this solution is a double-sided visual inspection system designed for curved backplanes

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] as attached Figures 1 to 14 The shown quality control system of the display backplane based on visual inspection includes the detected curved display backplane 8, and the two curved sides of the curved display backplane 8 are respectively recorded as the first curved side 8.1 and the second curved side 8.1. Two curved sides 8.2, the two straight sides of the curved display back panel 8 are respectively recorded as the first straight side 8.3 and the second straight side 8.4, and the midpoint of the first curved side 8.1 and the second curved side The line connecting the midpoints of 8.2 is recorded as the symmetry line 29;

[0035] It also includes fixed platform 103, visual camera 2 and flip mechanism directly above fixed platform 103. The flip mechanism can turn the curved display backboard 8 with the concave surface upwards into a convex surface; The camer...

Abstract

The invention discloses a display backboard quality control system based on visual inspection, which comprises a detected arc-shaped display backboard, two arc-shaped edges of the arc-shaped display backboard are respectively marked as a first arc-shaped edge and a second arc-shaped edge, two straight-line edges of the arc-shaped display backboard are respectively marked as a first straight-line edge and a second straight-line edge, and the first straight-line edge and the second straight-line edge are respectively marked as a first straight-line edge and a second straight-line edge. Marking a connecting line between the midpoint of the first arc edge and the midpoint of the second arc edge as a symmetric line; the arc-shaped plate can be turned over smoothly, so that an image processing system replaces human eyes to judge whether the surfaces on the concave surface and the convex surface of the arc-shaped display back plate are stained and damaged and whether burrs exist, and visual detection on the concave surface of the arc-shaped display back plate is realized; therefore, double-sided detection is realized and the process is simple and reliable.

Description

technical field [0001] The invention belongs to the field of visual detection of display backplanes. Background technique [0002] There may be surface stains and processing burrs in the production process of the curved backplane. It is cost-intensive and inefficient to use artificial and human eyes for detection and processing, and the consistency of detection is not good. Therefore, the existing CCD industry can be used Visual cameras are used to replace human eyes to judge whether there are stains or burrs on the surface; this solution is a double-sided visual inspection system designed for curved backplanes. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a quality control system for a visual inspection-based display backplane that can detect both sides. [0004] Technical solution: In order to achieve the above purpose, the quality control system of the display backpla...
