The control mode and circuit connection will not be explained in detail in this article.

[0041] The working process of an automated CT detection system:

[0042] Step1: The ray source is turned on. The opening and closing door 4 is in the closed state, and the door of the sample introduction box body 2 is opened. The sample is placed on the sample introduction chassis 54. Then the door of the sample introduction box body 2 is closed. After forming a sealed space, the opening and closing door 4 of the main box body 1 is opened by the rod of the first push rod cylinder 41 extending.

[0043] Step2: The opening and closing door 4 is opened, and the sample introduction platform 5 is used to send the sample on the sample introduction chassis 54 into the main box body 1 by using a two-stage motion mode.

[0044] Step3: In this embodiment, two five-degree-of-freedom sample detection platforms 8 are provided to synchronously detect two samples and improve the detection efficiency. As Figure 3 shown, the five-degree-of-freedom sample detection platforms on both sides respectively use the XYZ three-way motion structure in this mechanism to move the rotation assembly 83 to the position of the sample introduction chassis 54 and realize the grasping of the sample. Subsequently, the sample introduction platform 5 withdraws into the sample introduction box body 2. The opening and closing door 4 of the main box body 1 is closed by the cylinder retracting, making the inside of the main box body 1 a sealed space. And the door of the sample introduction box body 2 is opened by the horizontal cylinder retracting, and the next artificial feeding or external manipulator feeding can be carried out.

[0045] Step4: The sample inside the sealed space of the main box body 1 realizes three-way displacement of the sample to below the CT detection assembly through the three-way transmission structure 81, and realizes two-sided flipping of the sample through the flipping cylinder 821, and drives the sample to rotate through the rotating motor to realize full-angle scanning of the sample.

[0046] Step 5: After the scanning is completed, the opening and closing door 4 in the main cabinet 1 is opened. The sample discharging platform 6 sends the discharging platform into the main cabinet 1 through the two-stage moving platform, and then places the sample and the sample tray on the discharging tray through the three-way transmission structure 81.

[0047] Step 6: After the sample is placed on the discharging tray, the sample discharging platform 6 sends the discharging platform out of the main cabinet 1 through the two-stage moving platform. After entering the discharging cabinet, the opening and closing door 4 of the main cabinet 1 closes by retracting the air rod of the cylinder. Then, the door of the sampling cabinet 3 is opened by retracting the horizontal cylinder. The sample is taken out manually or by a manipulator mechanism, and the door of the sampling cabinet 3 is closed by extending the horizontal cylinder. The subsequent process of loading and unloading samples is cycled according to steps 1-6.
