Embodiment 1

[0056] A specific embodiment of the present invention discloses a dual-manipulator digital radiation detection device,

[0057] The device includes a ray source, a detector, a workpiece turntable, a first mechanical arm, a second mechanical arm, a control system and a data acquisition system;

[0058] The first mechanical arm and the second mechanical arm are placed on opposite sides of the workpiece turntable, and the radiation source and detector are installed on the first mechanical arm and the second mechanical arm respectively; the workpiece to be measured is installed on the workpiece turntable; the data acquisition system is used To collect detector imaging data;

[0059] The control system changes the position and direction of the detector and the ray source by adjusting the movement axes of the first mechanical arm and the second mechanical arm, so as to realize the detection of the workpiece; the central beam of the ray source is always perpendicular to the surface o...

Embodiment 2

[0095] Another embodiment of the present invention provides an automatic detection method based on a double-manipulator digital radiation detection device, including the following steps:

[0096] S1. The control system runs the robotic arm control program;

[0097] S2. The control system controls the ray source and the detector to move to the i-th scanning path point, and the initial value of i is 1;

[0098] S3. The control system outputs an instruction to start collecting signals to the data acquisition system, then executes the input waiting instruction, and waits for the data acquisition system to complete data acquisition;

[0099] S4. After the data acquisition system receives the instruction to start collecting signals, it turns on the ray source and the detector, and collects the data output by the detectors, and outputs a collection completion signal to the control system after the collection is completed;

[0100] S5. After the control system receives the collection...

Abstract

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.

Description

[0001] The invention relates to the field of digital ray nondestructive testing, in particular to a double-manipulator digital ray testing device and an automatic testing method. Background technique [0002] Non-destructive testing is an indispensable tool in industrial development, which reflects a country's industrial development level to a certain extent. As a conventional non-destructive testing method, X-ray testing technology has been used in the industrial field for nearly a hundred years. In the early days and in some current industrial fields (such as the field of military manufacturing), X-ray inspection usually uses film photography as the main detection method. And other problems, it has not adapted to the development trend of non-destructive testing in the information age. At present, digital ray nondestructive testing technology has been widely used in the industrial field. On the premise of ensuring the quality of product inspection, digital ray nondestructiv...
