[0002] An X-ray image acquisition and detection device is a device that uses X-rays to acquire and detect images. It projects X-rays onto the object to be detected and uses the penetrating and differential absorption characteristics of X-rays to convert the internal structural information of the object into an observable image, thereby enabling the observation and analysis of the internal structure and condition of the object. Because it can detect the interior of an object without causing damage to the object, it is widely used in manufacturing, electronics, medicine and other fields.

[0029] See also Figure 1-6 , the utility model provides a technical solution:

[0030] See Figure 1-6 As shown, an X-ray image acquisition and detection device includes a box body 10 and a box door 11 rotatably connected to the front opening of the box body 10, a vertical rotating groove 1 is provided at the center of the bottom inner side wall of the box body 10, and a fixing component 20 is provided in the rotating groove 1, the fixing component 20 includes a fixing ring 24 rotatably connected to the bottom end of the inner arc wall of the rotating groove 1, three electric telescopic rods 26 distributed in a circular array are fixedly connected to the inner arc wall of the fixing ring 24, and the three electric telescopic rods 26 are abutted against the same rotating shaft 25 at one end close to each other, and a turntable 23 is fixedly connected to the top of the fixing ring 24, and a vertical rotating groove 2 is provided at the top center of the turntable 23, and a rotating shaft 1 22 is fixedly connected to the top center of the rotating shaft 25, and the end of the rotating shaft 1 22 away from the rotating shaft 25 is rotatably connected to the rotating groove 2, and a turntable 1 21 is fixedly connected to the top of the rotating shaft 1 22, and eight sliding passages distributed in a circular array are provided on the top of the turntable 1 21.

[0034] See Figure 1-6 As shown, an X-ray image acquisition and detection device is shown, wherein the sliding channel 1 on the turntable 1 21 is rectangular, and the length direction of the sliding channel 1 is consistent with the diameter extension direction of the turntable 1 21, the eight sliding channels 1 do not interpenetrate each other, and the eight slide grooves 1 are all arc-shaped. Three arc-shaped grooves 1 are distributed in a ring array on the outer arc wall of the rotating shaft 25, and the three grooves 1 correspond one-to-one to the three electric telescopic rods 26.

[0036] Working principle:

[0037] First, place the object to be inspected at the top center of turntable 1 21, then rotate shaft 25 clockwise to drive the eight clamping assemblies 30 to gather inward to fix the object, and then the X-ray generator 40 works to scan and detect the object. During this period, if the horizontal angle of the object needs to be adjusted, the three electric telescopic rods 26 are extended and inserted into the corresponding groove 1. Keeping the rotation in the same direction as turntable 1 21, the fixing assembly 20 can be rotated as a whole to adjust the horizontal angle. If the vertical angle needs to be adjusted, the moving assembly 50 will move in the slide groove 2 to drive the X-ray generator 40 to adjust the scanning angle.
