Industrial CT detection device and method based on 3D sphere detection platform

Abstract

The invention discloses an industrial CT detection device and method based on a 3D sphere detection platform. The device is composed of a movable suspension arm unit, the 3D sphere detection platform, a radiation source detector scanning unit and a system console. Information feedback and collection are conducted through the system console, then a driving control instruction is sent, and then a movable radiation source and a detector reach a predetermined detection position. A universal driving wheel unit in the 3D sphere detection platform is controlled and driven to roll, so as to drive a spherical workpiece tray containing a workpiece to rotate along a required detection track, and scanning imaging is conducted through the radiation source detector scanning unit at the same time so that CT scanning detection can be achieved. An X ray machine and a linear accelerator are adopted as a radiation source, a linear array detector or digital flat-panel detector is used as an image detecting and receiving unit, detection range is widened greatly, traditional technical defects are overcome, detection sensitivity and precision are improved greatly, and the method is a better programmed industrial CT scanning detection method.

Description

technical field [0001] The invention relates to an industrial CT detection device and a detection method, in particular to an industrial CT detection device and a detection method based on a 3D ball detection platform. Background technique [0002] In recent years, with the continuous popularization and development of computer technology, industrial CT detection technology has been further developed. Through X-ray tomography, in the form of two-dimensional tomographic images or three-dimensional images, it can clearly, accurately and intuitively display the image of the detected object. Internal structure, composition, material and defect condition. The CT scan mode in the prior art is a translation and rotation mode or a single rotation mode. The workpiece is placed vertically and clamped on the rotating platform, and scanned and detected by rotation and translation. At present, for the industrial CT detection of large workpieces such as cube structures or spherical struc...

Problems solved by technology

Although the disclosed device can be flipped at a certain angle, the flip detection angle provided is very limited, and the applicability is also very limited, and the device cannot effectively detect the position of the workpiece clamped at the bottom of the pallet at one time due to the clamping block. detection
