DETAILED DESCRIPTION

[0023] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0024] like Figures 1 to 3 As shown, a micro-focus X-ray online high-speed detection system includes a conveyor line and a driving device for its operation. The conveyor line is provided with two parallel staggered detection gaps as detection areas. Matching ray machines i and detectors are respectively provided above and below the detection gaps for collecting image information of samples to be detected passing through the detection gaps. The detector triggers imaging through a trigger e. The output end of the detector is connected to an industrial computer f for transmitting the image information of the samples to be detected to the industrial computer f. In this embodiment, the industrial computer f is arranged below the conveyor line, and a high-voltage generator m is provided on one side of the industrial computer f for providing X-rays to the ray machine i. The industrial computer f and the high-voltage generator m are fixedly connected to a frame, and the top of the frame supports the conveyor line, so that the entire detection system is integrated.

[0025] In this embodiment, the conveyor line includes a first conveyor belt a1 and a second conveyor belt a2 arranged side by side, and the driving device includes a first driving motor g1 and a second driving motor g2; wherein,

[0026] The first conveyor belt a1 is composed of two independently running conveyor belts, wherein the first conveyor belt is driven by the first drive motor g1 for in-testing, and the second conveyor belt is driven by the second drive motor g2 for out-testing, and the gap between the two conveyor belts forms a first testing gap;

[0027] The second conveyor belt a2 is also composed of two independently running conveyor belts, wherein the first conveyor belt is driven by the first drive motor g1 for in-testing, and the second conveyor belt is driven by the second drive motor g2 for out-testing, and the gap between the two conveyor belts forms a second testing gap;

[0028] The first detection gap and the second detection gap are staggered between the first conveyor belt a1 and the second conveyor belt a2, which are arranged side by side, to avoid the sample to be detected from being suspended in the first detection gap and the second detection gap at the same time. When the sample to be detected is suspended, it is easy to be misaligned or deformed, which affects the detection accuracy. The staggered distribution ensures that the sample to be detected does not hang in the air when passing through, thereby ensuring the accuracy.

[0029] The first drive motor g1 and the second drive motor g2 are connected to the industrial computer f through the motion control mechanism j, which is used to feedback the position of the sample to be detected and control the start and stop of the first drive motor g1 and the second drive motor g2. In the specific implementation, the corresponding position sensor can be set to cooperate with the motion control mechanism j to monitor and position the sample to be detected in real time.

[0030] The detector includes a first detector d1 and a second detector d2, the first detector d1 is arranged below the first detection gap, and the second detector d2 is arranged below the second detection gap. The first detector d1 and the second detector d2 are linear array high-speed detectors, and the control ends of the first detector d1 and the second detector d2 are connected to the motion control mechanism j through a trigger e, which is used to trigger the first detector d1 and the second detector d2 to respectively collect and synthesize images according to the feedback of the position of the sample to be detected.

[0031] A first safety door b1 and a second safety door b2 are provided at a distance on the inlet section of the conveyor line, and a third safety door b3 and a fourth safety door b4 are provided at a distance on the outlet section of the conveyor line, which are used to separate samples to be tested and block the rays of the ray machine i.

[0032] The first safety door b1 and the second safety door b2 are connected to the door control module h through the first door control mechanism c1, and the third safety door b3 and the fourth safety door b4 are connected to the door control module h through the second door control mechanism c2. The door control module h is connected to the industrial computer f, which is used to independently control the opening and closing of the four safety doors to ensure that only one of the two safety doors on the entry inspection section and the exit inspection section is opened at the same time to prevent radiation leakage.

[0033] A first protective cover k1 is provided on the side periphery of the conveying line, and a second protective cover k2 is fully enclosed around the radiation machine i, the detection gap and the detector to prevent radiation leakage.

[0034] The first protective cover k1 and the second protective cover k2 are made of lead.

[0035] Principle of the Invention

[0036] When performing the detection work, the industrial computer f controls the first conveyor belt a1 and the second conveyor belt a2 to move from left to right, and controls the door control module h, the X-ray machine i, the first detector d1, the second detector d2 and the motion control mechanism j to work together;

[0037] The sample to be tested is smoothly transported from the first conveyor belt a1 and the second conveyor belt a2 in the direction of left-in and right-out;

[0038] Among the four safety doors, the two on the conveyor line's inlet inspection section are the first group (the first safety door b1 and the second safety door b2), and the two on the conveyor line's outlet inspection section are the second group (the third safety door b3 and the fourth safety door b4). Only one of the two safety doors in each group can be opened at the same time to ensure absolute safety;

[0039] The first door control mechanism c1 and the second door control mechanism c2 form a self-contained loop, respectively controlling the first group of safety doors and the second group of safety doors, ensuring that only one of the two safety doors in each group can be opened at the same time;

[0040] The X-ray machine i is always on during the operation of the system, and the trigger e receives the feedback pulse from the motion control mechanism j, triggering the misaligned first detector d1 and the second detector d2 to collect and synthesize images, which are then transmitted to the industrial computer f;

[0041] The industrial computer f automatically identifies defects in the received composite image.

[0042] In addition, it should be noted that, unless otherwise specified or indicated, the terms "first", "second", "third", etc. in the specification are only used to distinguish the various components, elements, steps, etc. in the specification, and are not used to indicate the logical relationship or sequential relationship between the various components, elements, steps, etc.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
