[0034] An X-ray receiving device 6 is installed in the bottom square base 1.

[0035] Continue to refer to Figures 1 to 6 As shown, in this embodiment, one of the first brackets 51 is slidably connected to the middle-layer square bracket 2 via a slide rail, and a spacing adjustment mechanism 52 is connected to the first bracket 51. The spacing adjustment mechanism 52 can adopt a motor screw transmission method to drive the first bracket 51 to be close to or away from another first bracket 51, thereby adjusting the spacing between the two to adapt to the transmission of products of different sizes and specifications; each transmission belt module 54 includes a driving wheel, a plurality of transmission wheels, a transmission shaft connected between the two driving wheels, and a transmission belt wound between the driving wheel and the transmission wheel. The transmission motor assembly 55 is connected to the transmission shaft, and the transmission motor assembly 55 drives the transmission belt to operate via the transmission shaft, the driving wheel, and the transmission wheel, thereby transmitting the product; in addition, in this embodiment, a product blocking mechanism 56 is also included, and the product blocking mechanism 56 can block and position the product so as to detect it.

[0036] At the same time, the X-ray emitting device 4 includes an emitting Y-axis translation mechanism 41 installed in the top-level square frame 3, an emitting X-axis translation mechanism 42 connected to the emitting Y-axis translation mechanism 41, an emitting translation plate 43 connected to the emitting X-axis translation mechanism 42, an emitting Z-axis lifting mechanism 44 installed on one side of the emitting translation plate 43, and a emitting lifting plate connected to the emitting Z-axis lifting mechanism 44; an X-ray emitter 45 is also installed at the bottom of the emitting lifting plate. The transmitting Y-axis translation mechanism 41 and the transmitting X-axis translation mechanism 42 can both directly adopt the transmission mode of the motor screw, and the transmitting Z-axis lifting mechanism 44 adopts the transmission mode of adjusting the hand wheel and the screw (due to the diversification of the detected products, the magnification of the equipment remains unchanged, that is, the X-ray emitter 45 is installed on the transmitting Z-axis lifting mechanism 44, so that the movement space range of the X-ray emitter 45, that is, the upper space range is fixed, and the flat panel detector 64 movement mechanism can be seen in the front view that the space in the Z-axis direction has been compressed to the extreme, so as to ensure the reasonable use of the middle-level transmission device and the lower-level movement space, and make the whole volume of the equipment compact). Through the mutual cooperation of the three, the horizontal position and height of the X-ray emitter 45 (X-ray source) can be adjusted to detect the product. At the same time, a first connecting plate 46 is connected to one side of the transmitting lifting plate, and a CCD camera assembly 47 is also installed on one side of the first connecting plate 46.

The receiving Y-axis translation mechanism 61 and the receiving X-axis translation mechanism 62 can both directly adopt the transmission mode of the motor screw rod to drive the flat panel detector 64 to perform translational movement. At the same time, a waist-round through hole 65 is opened on one side of the receiving translation plate, and a second locking hole is opened on the first adjustment seat 63 at a position corresponding to the waist-round through hole 65. In this embodiment, the X-ray receiving device 6 no longer requires a Z-axis driving mechanism (which can reduce space and save costs). After manually fine-tuning the height of the flat-panel detector 64, the screws can be tightened in the second locking hole and the waist through hole 65. The purpose of fine-tuning the flat-panel detector 64 is to facilitate the use of the flat-panel detector 64 in conjunction with the X-ray emitter 45. The main magnification of the equipment is still adjusted by the Z-axis lifting mechanism 44 of the X-ray emitter 45.

[0038] During operation, firstly, the spacing between the two first brackets 51 is adjusted accordingly through the spacing adjustment mechanism 52 according to the size of the product to be transmitted, and then, the transmission motor assembly 55 drives the transmission belt module 54 to operate so as to transmit the product to the predetermined inspection station, and then, the product is stopped and limited by the product blocking mechanism 56; then, the CCD camera assembly 47, through the linkage of the transmitting X-axis translation mechanism 42 and the transmitting Y-axis translation mechanism 41, first shoots the product identification position, calculates and matches the actual position of the product with the theoretical position, so as to realize the visual positioning of the product, and then the transmitting Z-axis lifting mechanism 44 drives the X-ray emitter 45 to automatically adjust the detection magnification of the product, and finally the X-ray emitter 45 and the flat-panel detector 64 are linked to detect the product to be inspected. After the inspection is completed, the product flows out of the equipment through the product transmission device 5 and enters the next process of the production line.

[0039] In one embodiment, the product blocking mechanism 56 comprises a first fixed plate 561 installed on one side of the first bracket 51, a blocking cylinder 562 installed on one side of the first fixed plate 561, and a blocking translation plate 563 connected to the blocking cylinder 562; the blocking translation plate 563 is located above the first bracket 51, and one end of the blocking translation plate 563 extends toward the top of the conveyor belt module 54. The blocking cylinder 562 can drive the blocking translation plate 563 to translate, thereby blocking the limited product. At the same time, the first bracket 51 is provided with a side of the first fixed plate 561 is also connected to a first adjustment plate 564, and a plurality of first mounting holes 565 are spaced apart on one side of the first adjustment plate 564 in the length direction; the first fixing plate 561 is also provided with a first locking hole 566 at a position corresponding to the first mounting hole 565. The position of the first fixing plate 561 can be adjusted according to actual usage requirements, and then the screws can be tightened in the first locking hole 566 and the first mounting hole 565. In addition, the top of the first bracket 51 is also connected to a first limiting block 567, and one side of the first limiting block 567 is also provided with a first limiting hole that passes through the other side thereof; the blocking translation plate 563 is movably arranged through the first limiting hole.

[0040] In one embodiment, the bottom square tube base 1 includes a first support platform 11, and the X-ray receiving device 6 is installed on the first support platform 11; the four corners of the first support platform 11 are respectively connected to a first support column 12, and the tops of each two adjacent first support columns 12 are respectively connected to a support beam 13; the middle square tube bracket 2 includes a first support plate 21 installed on the support beam 13, and a first support frame 22 is installed at each of the two ends of the top of the first support plate 21; the product transmission device 5 is installed on the first support plate 21, and the first through hole 53 is opened in the middle of the first support plate 21; the top square tube frame 3 is installed on the first support frame 22; the transmitting Y-axis translation mechanism 41 is provided with two, and the two transmitting Y-axis translation mechanisms 41 are respectively installed on the top of a first support frame 22.

[0041] In this embodiment, the bottom square tube base 1 in the device is welded with a high-rigidity large square tube welding base. After the overall processing, the upper and lower surfaces of the base can achieve consistency. At the same time, the middle square tube bracket 2 is also welded by square tube. After the upper and lower mounting surfaces of the whole are consistent after processing, the whole is connected by assembly. In this way, the installation reference of the X-ray emitter 45 and the flat-panel detector 64 in the XY plane direction is unified. Because the efficiency improvement during equipment detection is mainly on the stable image of imaging, this method reflects the lower side as the center of gravity in the structural counterweight. When the module is linked, even if the acceleration and deceleration are large, the center of gravity of the equipment will not drift. In this way, the equipment is used in a ball screw module. When assembling, the high stability effect of the linear motor can also be achieved. In addition, during detection, the distance positions of the detection points are all within the millimeter range, so the ordinary ball screw module combined with the above-mentioned multi-layer skeleton can perfectly replace the action performance of the linear motor, so that high-rigidity, high-stability and high-efficiency detection equipment can be produced at low cost. The device distributes the X-ray emitter 45 to the upper layer of the product and the flat-panel detector 64 to the lower layer of the product. One can achieve a high magnification of the detection product, and the other can make the structure compact. When detecting products of the same area, the production volume of the whole machine can be greatly reduced, and the production cost of the whole machine is greatly reduced.

[0042] In one embodiment, the X-ray-based intelligent automated high-speed online inspection machine further includes an inspection frame, in which the bottom square tube base 1, the middle square tube bracket 2 and the top square tube frame 3 are all installed. Openings are provided on the left and right sides of the inspection frame, and the openings are equipped with lifting lead doors and safety gratings to improve the safety of operation.
