If you want to detect other areas of the product, you need to configure multiple X-ray detectors, which increases the occupied area and increases the cost. Therefore, it needs to be improved.

[0040] In one embodiment, the X-ray emitting device 6 further includes a second fixed frame 63, a first translation mechanism 64 arranged on the second fixed frame 63 in a direction perpendicular to the transmission direction of the product transmission device 2, a first translation frame 65 connected to the first translation mechanism 64, and a first stand 66 connected to the top of the first translation frame 65; the tilt swing adjustment mechanism 61 is installed on the first stand 66. In this embodiment, the first translation mechanism 64 directly adopts a linear motor module, which can drive the X-ray source 62 to translate, thereby adjusting the distance between the X-ray source 62 and the flat panel detector 71 to achieve detection of different magnifications.

[0041] At the same time, the tilt swing adjustment mechanism 61 includes a first fixed plate 611 installed on the upper part of one side of the first stand 66, a rotating pin installed on one side of the first fixed plate 611, and a first rotating frame 612 rotatably connected to the first fixed plate 611 via the rotating pin; the X-ray source 62 is installed on the first rotating frame 612; a locking block 613 is also installed at one end of the first rotating frame 612, and a first locking hole is also opened on the locking block 613; a second handle 614 is also installed at one end of the first rotating frame 612. The first rotating frame 612 can be manually rotated in advance to adjust the tilt angle of the irradiation beam of the X-ray emission port of the X-ray source 62 relative to the horizontal plane, and then the screw can be locked in the first locking hole, which is simple and convenient.

At the same time, a slot can be opened on one side of the second stand 74. After the height of the flat panel detector 71 is adjusted, it can be locked by screws.

[0043] During operation, first, the product to be tested is quickly clamped on the carrier jig 4 by the clamping clamp 53, and then the carrier jig 4 is placed on the loading transmission line 8, and the loading transmission line 8 drives the carrier jig 4 to be transmitted in the direction of the detection chassis 10. When it is transported to almost the detection chassis 10, the lifting lead door at one end of the detection chassis 10 is opened, and then the translation drive mechanism 22 drives the transmission frame 21 to move, so as to extend the transmission frame 21 to the outside of the detection chassis 10 and dock with the loading transmission line 8. Then, the loading transmission line 8 transmits the carrier jig 4 to the transmission chain module 26, and the translation drive mechanism 22 drives the transmission frame 21 to move into the detection chassis 10, and the lifting lead door is closed; then, the transmission chain module 26 continues to transmit the carrier jig 4 to the preset detection position, and the stopping mechanism 24 (the stopping mechanism 24 can be installed on the first connecting plate 25) stops it.

[0044] Subsequently, the first Z-axis lifting mechanism 32 drives the rotating platform 36 to rise, so that the positioning pin 37 on the rotating platform 36 is inserted into the second positioning hole 42 in the supporting fixture 4, and continues to lift until the supporting fixture 4 is completely separated from the transmission chain module 26; subsequently, the X-ray emitting device 6 and the X-ray receiving device 7 are automatically adjusted to a suitable position, so that the emission center line of the X-ray source 62 coincides with the detection surface center of the flat panel detector 71, and the magnification of the defect detection is automatically adjusted by the translation mechanism inside the X-ray emitting device 6 and the X-ray receiving device 7. After adjusting to a suitable magnification, the rotation drive mechanism 35 inside the lifting rotating device 3 drives the rotating platform 36 to rotate 360° in the horizontal plane. In this way, the carrier fixture 4 will also be driven to rotate 360° in the horizontal plane, so that the rotation axis is perpendicular to the center line of the X-ray source 62 and the flat-panel detector 71. At this time, the 360° horizontal plane imaging can form the cone beam scanning condition of the detection equipment. After the imaging is completed, the first Z-axis lifting mechanism 32 drives the rotating platform 36 to descend to put the carrier fixture 4 back on the transmission chain module 26; then, the lifting lead door at the other end of the detection chassis 10 is opened, and the translation drive mechanism 22 drives the transmission frame 21 to move, so as to extend the transmission frame 21 to the outside of the detection chassis 10 and dock with the unloading transmission line 9, the stopping mechanism 24 is reset, and the transmission chain module 26 is operated to transmit the carrier fixture 4 to the unloading transmission line 9.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
