Plank edge breakage detecting device

Abstract

The invention provides a plank edge breakage detecting device. The detection device comprises a housing, the top of the housing extends outwardly to form an upper platform, the bottom of the housing extends outwardly to form a lower platform corresponding to the upper platform, and a detection area for a plank to pass is arranged between the two platforms. Cameras facing the detection area are disposed above and below the detection area, respectively, each camera is provided with a light source emitting light to the plank edge in the direction close to the housing, and a light shielding unit is provided between the two light sources. The plank edge breakage detecting device detects whether or not there is edge breakage on the upper and lower surfaces of the plank using an upper camera anda lower camera simultaneously. An upper light source and a lower light source are adopted, and the light shielding unit is arranged between the two light sources to prevent the light from irradiatingdirectly the cameras at the corresponding positions while supplementing light for the cameras. The light sources are provided between the cameras and the housing such that the light sources can illuminate the edge of the plank.

Description

[0002] In board processing, especially wood board processing, in order to ensure the appearance of the board, it is usually necessary to apply paint on the board and perform edge sealing on the edge of the board. On the side wall of the edge, but in the process of sealing the edge, because the amount of glue used is not easy to control, the excess glue will overflow the area where the side wall of the board is located during the process of bonding the edge banding strip, polluting the surface of the board;

[0003] Moreover, during the process of wood board processing or edge sealing and bonding, the edge of the board is stressed, and at the same time, the board is prone to vibration and other phenomena during the processing process, causing the edge of the board to collapse, causing damage to the edge of the board, affecting the flatness of the board and the appearance of the board;

[0004] Nowadays, the upper and lower cameras are usually used to image the edge of the board, and then the corresponding recognition system is used to judge whether there is a defect on the edge of the board. During the imaging process of the camera, it is necessary to fill in the light on the edge of the board, but because the board is usually coated with paint, so that The surface of the wooden board is relatively smooth. After the light source is irradiated, it is easy to form light spots in the camera due to light reflection, resulting in poor image quality, which makes it easy for the post-recognition system to cause misjudgment.
