An improved six-sided detection device for plate production and its detection method

Abstract

The invention relates to an improved six-face detection device for plate production, which includes a belt drive device, a front end face detection mechanism, a rear end face detection mechanism and a four-side rotation detection mechanism; the front end face detection mechanism and the rear end face detection mechanism are respectively set At both ends of the belt transmission device; the four-sided rotation detection mechanism includes a rotating main body, a main body driving unit, two second image acquisition units and a camera driving unit; the rotating main body is a rectangular frame structure, and the rotating main body The two short sides 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 drive unit drives the rotating main body to rotate around the belt transmission device; the two sides of the rotating main body Guide rails are respectively provided on the inner sides of the long sides, the two second image acquisition units are respectively arranged in the two guide rails, and the camera drive unit drives the second 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
