Defect detection device for planed wood block

Abstract

The invention belongs to the technical field of wood block processing, and particularly relates to a planed wood block defect detection device which comprises a centrifugal machine, a first conveying belt, a second conveying belt, a third conveying belt and a defect detection mechanism. The second conveying belt is provided with a first detection area, and area-array cameras facing the first detection area are arranged on the front portion, the rear portion, the left portion, the right portion and the upper portion of the first detection area; a second detection area is arranged above a gap between the second conveying belt and the third conveying belt; and a linear array camera is arranged below the second detection area. Single wood blocks are thrown out to the first conveying belt through the centrifugal machine, and then the spacing distance between the wood blocks is increased through the speed difference between the second conveying belt and the first conveying belt; the five surfaces of the timber are photographed once through the front area-array camera, the rear area-array camera, the left area-array camera, the right area-array camera and the upper area-array camera; the linear array camera is used for scanning and photographing the lower portion of the wood block, the detection efficiency is high, the labor cost is saved, the reliability is high, and the probability of wrong detection and missing detection is reduced.

Description

technical field [0001] The invention belongs to the technical field of wood block processing, and in particular relates to a planed wood block defect detection device. Background technique [0002] In the production process of rubber wood materials, it is necessary to inspect the appearance defects of the materials of various sizes and specifications after cutting and planing, and determine the grade of planed materials according to the corresponding wood block surface quality standards, such as AA, AB, and BC , Cutting materials, etc., under normal circumstances, according to whether there are scars on the surface of the planed wood block, the position of the scar, and how many faces have scars. At present, manual inspection is used to classify planed materials. This position requires high professional skills, and it is difficult to recruit personnel. At the same time, the personnel training cycle is long, and the loss of personnel has a great impact on production. The effi...
