Automatic light guide plate defect detection and sorting equipment

Abstract

The invention discloses automatic light guide plate defect detection and sorting equipment. The equipment comprises a feeding mechanism, a defect detection mechanism, a discharging and sorting mechanism and an equipment frame, wherein the feeding mechanism uses a feeding manipulator and related hardware equipment, can realize position movement along X, Y and Z axes and takes charge of absorbing and conveying to-be-detected light guide plates on an assembly line to a defect detection area; a warping defect detection mechanism comprises an industrial area array camera and a linear array camera and can detect surface defects of the light guide plates; the discharging mechanism judges the discharging station of the discharging mechanism by use of the defect detection result and sorts qualifiedand defective light guide plates through a discharging manipulator. The whole automation degree is high, the equipment is simple in structure, stable in performance and simple and reliable to operateand can replace manual operation, realize full-automatic production, machining and intelligent detection of the light guide plates for enterprises and perform long-term continuous operation, the human resource is greatly saved, and the production efficiency of the enterprises is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of production and processing of light guide plates, in particular to the technical field of automatic defect detection and sorting equipment for light guide plates. 【Background technique】 [0002] The light guide plate is made of optical-grade acrylic / PC sheet, and then made of high-tech materials with extremely high reflectivity and non-absorbing light, molded on the bottom of the optical-grade acrylic sheet, laser engraved, V-shaped cross grid engraved, UV net Plate printing technology to print light guide points. The optical-grade acrylic plate is used to absorb the light emitted from the lamp to stay on the surface of the optical-grade acrylic plate. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. Through light guide points of various densities and sizes, the lig...
