The invention relates to a double-mechanical-arm
digital ray detection device and an automatic detection method, belongs to the field of
ray nondestructive detection, and solves the problems that in an existing workpiece detection
system, a movement mechanism is complex in design and large in control difficulty, automatic detection cannot be achieved, and vertical
transillumination detection cannot be achieved on workpieces with complex curved surfaces. The invention provides the double-mechanical-arm
digital ray detection device and the automatic detection method based on the detection device. According to the device, the two mechanical arms are arranged on the two sides of a workpiece to drive the
radiation source and the
detector to move, the control difficulty of a movement mechanism is lowered, and meanwhile detection of any position, any angle and any
magnification of the workpiece can be achieved. Meanwhile, on the basis of the device, automatic detection of the workpiece is achieved by writing a mechanical arm control program, and automatic detection of vertical
transillumination of the complex curved surface is achieved in the mode that scanning path points are obtained through
computer graphics on the basis of a workpiece three-dimensional model. The device and the method can be widely applied to the field of workpiece
nondestructive testing, the control difficulty is reduced, and the detection
automation is improved.
