Embodiment 1

[0024] image 3 It is a schematic diagram of the principle of laser triangulation ranging.

[0025] Such as image 3 Shown: the on-line detection device for the warping of wooden boards, including a workbench, a line laser transmitter 1 and an industrial camera 2, black cardboards are arranged around the workbench, and light blocking treatment is carried out so that the light received by the camera is only The emitted line laser, the line laser emitter 1 and the industrial camera 2 are all arranged on the top of the workbench, and the line laser emitter 1 is emitted to the surface of the wooden board 3 to be detected on the workbench after the light source is reflected by the wooden board Received by the industrial camera 2, and the industrial camera 2 communicates with a computer at the same time.

[0026] The online detection method of wooden board warpage is:

[0027] S1: The line laser emitter 1 emits a line laser to the wooden board 3 to be detected on the workbench to...

Abstract

The invention discloses a wood board warping online detection device which comprises a worktable, a linear laser emitter and an industrial camera.Black paperboards are arranged on the periphery of the worktable, and the linear laser emitter and the industrial camera are arranged on the upper portion of the worktable.A light source emitted by the linear laser emitter to the surface of a to-be-detected wood board on the worktable is reflected and then received by the industrial camera, and the industrial camera is connected with a computer at the same time.The invention discloses an online detection of the device.Compared with a manual detection method, the detection device and method have the advantages that laser online detection is high in efficiency, high in precision and the like; measurement is conducted through the triangulation ranging, measurement precision is improved, and industrial online detection is achieved.

Description

technical field [0001] The invention relates to a detection device and a detection method, in particular to an on-line detection device and a detection method for the warping of wooden boards, belonging to the field of wood processing and manufacturing. Background technique [0002] The main components of wood are cellulose, hemicellulose and lignin, which have sufficient affinity for the surrounding water vapor and moisture, resulting in the natural hygroscopicity of wood; wood is an organism composed of cells, which contains many Many capillaries have plasticity. To sum up the above reasons, wooden boards or wood products will shrink and swell with changes in the relative humidity of the surrounding environment. Since wood is a heterogeneous anisotropic material, its drying shrinkage and wet expansion also have anisotropy. Wooden boards placed in the natural environment will warp, and wooden boards in different temperature and humidity environments have different warping ...
