Plate defect detection device and detection method thereof

Abstract

The invention discloses a plate defect detection device. The device comprises a machine frame, a first conveying mechanism horizontally laid on the upper surface of the machine frame, a second conveying mechanism, a first support cross beam which is transversely connected with the first conveying mechanism in a bridge joint mode and a second support cross beam which is transversely connected withthe second conveying mechanism in a bridge joint mode, a width measurement device vertically extending toward the surface of the first conveying mechanism is installed on the first support cross beam,thickness measurement devices are installed on both sides of the first conveying mechanism, a first gap measurement device vertically extending toward the surface of the second conveying mechanism isinstalled on the second support cross beam, and a second gap measurement device is arranged in the scanning gap between the first conveying mechanism and the second conveying mechanism. The inventionalso discloses a detection method, and the method includes load adjustment, width and thickness detection, plate gap detection and detection data value processing. According to the device and the method, real-time and rapid detection of defects of plates is achieved, thereby achieving the purpose of high-speed and high-quality production.

Description

technical field [0001] The invention relates to the technical field of wood processing testing equipment, in particular to a board defect testing device and a testing method thereof. Background technique [0002] Defects on the surface of the board mainly rely on manual visual inspection. Inspectors use visual inspection methods to inspect the board under incandescent lamps. Insect eyes, knots, corrosion and other defects are evaluated. This manual detection method not only has a large detection error but is also easily affected by personal factors. The detection standards are often inconsistent among various detection personnel, which will cause the detection results to vary from person to person. , The phenomenon of missed inspection is unavoidable, resulting in uneven quality of the surface of the plate, low detection efficiency, high labor intensity, and working under the strong light of incandescent lamps for a long time, which is a great harm to the eyes of inspectors....

The detection standards are often inconsistent among various detection personnel, which will cause the detection results to vary from person to person. , The phenomenon of missed inspection is unavoidable, resulting in uneven quality of the surface of the plate, low detection efficiency, high labor intensity, and working under the strong light of incandescent lamps for a long time, which is a great harm to the eyes of inspectors. The progress and development of this kind of artificial detection method cannot meet the needs of the industrial production of plates. It is necessary to learn from the improvement experience in related fields to carry out technological transformation and industrial upgrading to improve the production and detection efficiency of plates.
