Description

Technical Field

[0001] The present invention relates to an industrial CT detection system, in particular to a batch industrial CT detection system. Background Art

[0002] Industrial CT (industrial computerized tomography) refers to nuclear imaging technology used in industry. Its basic principle is based on the attenuation and absorption characteristics of radiation in the object being tested. The absorption ability of a substance to radiation is related to the properties of the substance. Therefore, by using the attenuation law and distribution of X-rays or gamma rays with a certain energy and intensity emitted by radioactive nuclides or other radiation sources in the object being tested, it is possible to obtain detailed information inside the object through the detector display, and finally display it in the form of an image using computer information processing and image reconstruction technology.

[0003] The existing industrial CT inspection can only put the workpieces into the industrial CT imaging device one by one, and then take the workpieces out after completing the internal inspection. However, this manual inspection process is difficult to cope with batch inspection of workpieces. If an industrial robot is used to load and unload samples during inspection, it is necessary to design a robot gripper arm that can hold and place workpieces with various contours, which is difficult and costly. Therefore, the problem that needs to be solved urgently is how to solve the problem of loading and unloading most workpieces to be inspected, so that workpieces with various outer contours can be stably placed in the industrial CT imaging device. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a batch industrial CT detection system, which can automatically load and unload samples. The loading support frame can adaptively adjust the folding degree to match the outer contour of the workpiece. The loading support frame is used as a carrier for the entire process, avoiding unstable factors in loading and unloading samples, and can greatly improve the efficiency of loading and unloading samples.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

After the workpiece is placed on the material carrier support frame, the material carrier support frame can be adaptively adjusted in folding degree to match the outer contour of the workpiece;

[0009] The industrial CT imaging device is located at the end of the conveyor belt platform;

[0010] The side push mechanism pushes the material support frame and the workpiece carried to the end of the conveyor belt platform into the industrial CT imaging device. After the inspection is completed, the material support frame is pulled out of the industrial CT imaging device.

[0011] The circulating conveying crane mechanism includes a U-shaped crane guide rail and a crane arranged on the crane guide rail.

[0012] Further, the material loading support frame includes a fork-shaped support frame;

[0013] The material loading support frame comprises two groups of cross bars and a horizontal cross bar connected between the two groups of cross bars. Each group of cross bars is composed of two oblique bars. The horizontal cross bar serves as a rotation axis and passes through the intersection of the two oblique bars.

[0014] Furthermore, the two oblique rods are connected with an elastic connecting piece, which is an elastic rubber.

[0015] Furthermore, rubber convex particles and elastic rubber layers are respectively arranged at the relative positions in the shear direction of the two oblique rods, and the rubber convex particles and elastic rubber layers are both made of natural rubber materials.

[0016] Furthermore, the material loading support frame is made of non-metallic material.

[0017] Furthermore, the batch industrial CT detection system also includes a support frame opening mechanism, which opens the loading support frame transported to the starting end of the conveyor belt platform to a preset angle.

[0018] Furthermore, a rubber limiting groove is provided on the conveyor belt surface of the conveyor belt platform to increase the friction force at the bottom end of the loading support frame, thereby maintaining the opening angle of the loading support frame.

[0019] Furthermore, the support frame opening mechanism includes a screw, a working platform, a bidirectional cylinder, a servo motor, and a transmission gear;

[0020] The output end of the servo motor is connected to the transmission gear; the servo motor is connected to an external computer terminal.

[0022] The working platform is provided with a vertical internal screw hole, and the screw rod passes through the internal screw hole; when the servo motor receives an electrical signal to operate, the screw rod is driven to rotate through the gear, so that the height position of the two-way cylinder can be adjusted to a certain amount, thereby better realizing the action of expanding the loading support frame, and at the same time, it can be quickly retracted after expanding.

[0023] The bidirectional cylinder is connected to an external compressor and releases the pressure body through a solenoid valve.

[0024] Furthermore, the batch industrial CT detection system also includes a feeding mechanism;

[0025] The feeding mechanism comprises a pulley rail and a mechanical clamping claw arranged on the pulley rail;
