Problems solved by technology

One of the disadvantages of this method is that the inner edge of the rough edge is identified by the naked eye, and the labor intensity of the worker is high during work, which is easy to visual fatigue; secondly, the rough edge board is required to be stationary when judging the inner edge of the rough edge, which reduces the work efficiency; Once again, this method needs control systems such as special guide rails and servo motors when it is used, and the cost is relatively high and it is difficult to promote

Embodiment 1

[0049] The horizontal movement speed of the transmission table 1 is 500mm / s, and the laser transmitter 2 emits a fan-shaped light source to scan the wooden board under test on the transmission table 1. The wavelength of the laser emitted light is 660nm, and the fan angle of the light is 90°; the surface of the wooden board 4 under test The reflected light is received by the area array industrial camera 5, the pixel size of the image is 1920×1200, the area array industrial camera 5 shoots 100 images per second, and the focal length of the lens is 50mm.

[0050] Figure 6 It is the laser inspection picture when there is no plate.

[0051] like Figure 6 Shown: There is only one reference bottom line in the laser inspection diagram.

[0052] Figure 7 It is a laser inspection diagram of a regular plate without burrs.

[0053] like Figure 7 Shown: The surface of the sheet without burrs is imaged as a straight line.

[0054] Take a rough-edged plate with a thickness of 30mm,...

Abstract

The invention discloses a wooden board burr identification device comprising a transmission table, a laser emitter, a support and an area-array industrial camera. The support is erected on the transmission table in a bridging way. The laser emitter and the area-array industrial camera are arranged on the support above the transmission table in turn along the transmission direction of the transmission table, and the light source emitted to the surface of a measured wooden board by the laser emitter is reflected by the measured wooden board and then received by the area-array industrial camera, and the area-array industrial camera is also connected with a computer.. The invention also discloses a wooden board burr identification method. According to the method, manual operation is not required in detecting wooden board burrs so that automation can be realized; besides, the measured wooden board is in the continuous transmission process in measurement so that the working efficiency can be enhanced; meanwhile, the used identification device is simple in structure, convenient to install and low in cost.

Description

technical field [0001] The invention relates to an identification device and an identification method, in particular to an identification device and an identification method for the burrs of wooden boards, belonging to the field of wood processing and manufacturing. Background technique [0002] In recent years, my country's timber industry has developed rapidly, but the scope of forest resource exploitation is gradually decreasing. Forest resources are facing a serious shortage problem, and the contradiction between supply and demand of timber is becoming increasingly acute. This puts forward higher and higher demands on maximizing the value of timber resources Require. In the case of lack of wood resources, improving the utilization of wood is an urgent problem in the field of wood processing and automation. In the processing and production of many wood products, logs are sawed into boards with a certain thickness. The cross-section of the log can be approximately regarde...
