Improved six-surface detection device for plate production and detection method thereof

Abstract

The invention relates to an improved six-surface detection device for plate production. The improved six-surface detection device comprises a belt transmission device, a front end surface detection mechanism, a rear end surface detection mechanism and a four-surface rotation detection mechanism; the front end surface detection mechanism and the rear end surface detection mechanism are arranged atthe two ends of the belt transmission device respectively; the four-surface rotation detection mechanism comprises a rotation main body, a main body driving unit, two second image acquisition units and a camera driving unit; the rotating main body is of a rectangular frame structure, the two short edges of the rotating main body are hinged to the two ends of the belt transmission device, and the belt transmission device is located in the rotating main body; the main body driving unit drives the rotating main body to rotate around the belt transmission device; guide rails are arranged on the inner side faces of the two long edges of the rotating main body respectively, the two second image acquisition units are arranged in two guide rails respectively, and the camera driving unit drives thesecond image acquisition units to reciprocate along the guide rails.

Description

technical field [0001] The invention belongs to the field of plate production, and in particular relates to an improved six-face detection device for plate production and a detection method thereof. Background technique [0002] Boards are flat rectangular building material boards of standard size that are processed and cut to form. Boards are widely used in the construction industry as components for walls, ceilings or floors. It can be seen that panels are an important part of building components in the market. Therefore, the quality of panels often determines the safety performance of building components. The yield detection of panels such as size and defect detection has also become a key link in the field of panel production. [0003] In the traditional plate detection technology, the detection of the plate includes the positive and negative surfaces of the plate. Most of the existing detection machines first detect one surface of the plate, and then turn the plate over...

Problems solved by technology

However, in the process of image acquisition, since the distance between the CCD camera and the plate and the relative position to the plate are fixed, the shooting range of the CCD camera is limited. When the length of the plate is long, the CCD camera acquires The image cannot cover the entire surface of the plate, resulting in a detection dead angle, and the obtained parameters are prone to deviation values

At the same time, in the Chinese patent CN107966102A, six CCD cameras need to be set up to take images of the six sides of the plate respectively, and the cost is high
