[0015] 2) This equipment demonstrates excellent maintenance economy.

The operation process does not require professional instruments and can be completed using conventional calipers, levels and other tools. At the same time, thanks to the minimalist fixed structure design, the equipment does not need to regularly lubricate and maintain the precision transmission mechanism like traditional rotating devices, and it also eliminates the complex troubleshooting, component calibration and other maintenance links of the electrical control system. This "simplifying the complex" design concept has greatly reduced the frequency of consumables replacement and professional maintenance manpower investment, and fundamentally achieved controllable and transparent maintenance costs.

[0016] 3) The installation process of this equipment is simplified. It does not require complicated debugging and precise calibration operations. Ordinary technicians can quickly get started after basic training, which greatly reduces the dependence on professional installers, significantly reduces labor costs and time investment, and saves human and economic resources in the installation process for enterprises.

A three-color light is installed on the top of the chassis, and a foot cup is installed at each of the four corners of the bottom of the chassis. During work, first set the scanning parameters (voltage, current, movement speed), start the detection system, and the product is accurately grabbed from the material storage area and placed on the product transmission device 2; subsequently, the product transmission device 2 transports the product to the detection position, and the biaxial translation device 1 drives the product transmission device 2 to drive the product to move in two directions of X / Y in a preset trajectory. After the X-ray emitting device 4 emits a conical beam to penetrate the product, the X-ray receiving device 3 synchronously collects X-ray projection data.

In one embodiment, the X-ray receiving device 3 includes a mounting cross beam 31; at both ends of one side of the mounting cross beam 31, a first fixing plate 32 is connected respectively, and on one side of each first fixing plate 32, an X-ray receiving mechanism 33 is mounted respectively; in the middle of one side of the mounting cross beam 31, a second fixing plate 34 is connected, and on one side of the second fixing plate 34, a visual positioning mechanism 35 is mounted; the ends of the two X-ray receiving mechanisms 33 for receiving signals are arranged obliquely downward towards the lower direction of the visual positioning mechanism 35; the X-ray receiving mechanism 33 includes a first adjusting plate 331 obliquely arranged on one side of the first fixing plate 32, a second adjusting plate 332 arranged on one side of the first adjusting plate 331, a mounting vertical plate 333 arranged perpendicular to the second adjusting plate 332 and connected to the second adjusting plate 332, and an X-ray receiver 334 mounted on one side of the mounting vertical plate 333.

[0026] In one embodiment, the biaxial translation device 1 includes a mounting base plate and a Y-axis translation plate 11. At both ends of the top of the mounting base plate, a Y-axis slide rail is arranged respectively, and on one side of each Y-axis slide rail, a Y-axis translation mechanism 12 is correspondingly arranged. At both ends of the bottom of the Y-axis translation plate 11, they are respectively slidably arranged on a Y-axis slide rail, and at both ends of the bottom of the Y-axis translation plate 11, they are also respectively correspondingly connected to a Y-axis translation mechanism 12. A second through hole is opened in the middle of the top of the Y-axis translation plate 11. On both sides of the top of the Y-axis translation plate 11, an X-axis slide rail is arranged respectively, and on one side of each X-axis slide rail, an X-axis translation mechanism 13 is correspondingly arranged. The product transfer device 2 is slidably arranged on the X-axis slide rail and is connected to the X-axis translation mechanism 13.

[0027] Both the Y-axis translation mechanism 12 and the X-axis translation mechanism 13 adopt the transmission mode of a motor and a lead screw. The present invention does not limit this. Under the mutual cooperation of the Y-axis translation mechanism 12 and the X-axis translation mechanism 13, the product transfer device 2 can be driven to drive the product to move along the X-axis and the Y-axis, thereby facilitating the detection of each part of the product. At the same time, in order to limit the moving stroke of the product transfer device 2, a stop seat 14 is installed at each end of the X-axis slide rail, and a stop block 15 is also installed on the relative side of the two stop seats 14.

[0028] In one embodiment, the product transfer device 2 includes a transfer base plate 21, a transfer fixing frame 22, a transfer moving frame 23, a transfer driving mechanism 24, and a spacing adjustment mechanism 25. At both sides of the bottom of the transfer base plate 21, they are respectively slidably arranged on an X-axis slide rail, and at both sides of the bottom of the transfer base plate 21, they are also respectively correspondingly connected to an X-axis translation mechanism 13. A third through hole is opened at the position corresponding to the second through hole in the middle of the top of the transfer base plate 21, and linear slide rails are arranged at both ends of the top of the transfer base plate 21. The transfer fixing frame 22 is fixedly installed on one side of the top of the transfer base plate 21, the transfer moving frame 23 is arranged on the other side of the top of the transfer base plate 21, and at both ends of the bottom of the transfer moving frame 23, they are respectively slidably connected to a linear slide rail. The spacing adjustment mechanism 25 is connected to the transfer moving frame 23, and the spacing adjustment mechanism 25 is used to drive the transfer moving frame 23 to move along the linear slide rail. A transfer belt module 26 is also installed on the relative side of the transfer moving frame 23 and the transfer fixing frame 22, and the transfer driving mechanism 24 is installed on the transfer base plate 21 and is connected to the two transfer belt modules 26.

[0029] The spacing adjustment mechanism 25 can drive the transfer moving frame 23 to move closer to or away from the transfer fixed frame 22 to adjust the spacing between the two, so as to adapt to the transfer of products with different size specifications, with strong versatility. At the same time, the spacing adjustment mechanism 25 includes a width adjustment motor 251 and two ball screws 252. The width adjustment motor 251 is installed on the transfer bottom plate 21, and the output shaft of the width adjustment motor 251 is also drivingly connected with a first coupling. The two ball screws 252 are arranged in parallel at intervals between the transfer fixed frame 22 and the transfer moving frame 23, and one end of each ball screw 252 is rotatably connected to one side of the transfer fixed frame 22. A ball nut is also installed on each ball screw 252, and the transfer moving frame 23 is connected to the two ball nuts. The other end of each ball screw 252 also passes through the transfer moving frame 23, and one end of the ball screw 252 passing through the transfer moving frame 23 is also connected to the first coupling. A transmission wheel 253 is also installed on one end of each ball screw 252 passing through the transfer moving frame 23, and a transmission belt 254 is wound between the two transmission wheels 253.

[0030] The width adjustment motor 251 can drive the connected ball screw 252 to rotate through the first coupling. Since the two ball screws 252 are connected by the transmission wheels 253 and the transmission belt 254, the other ball screw 252 can be driven to rotate synchronously. At the same time, the transfer moving frame 23 is connected to the ball nuts installed on the ball screws 252. Therefore, when the ball screws 252 rotate, the transfer moving frame 23 can be driven to move through the ball nuts, so as to adjust the spacing between the transfer moving frame 23 and the transfer fixed frame 22 to meet the transfer requirements of products with different sizes.

[0031] In addition, the conveyor belt module 26 includes a plurality of synchronous wheels and a synchronous belt wound around the synchronous wheels. The transfer driving mechanism 24 includes a transfer motor 241 installed on the transfer bottom plate 21, a second coupling connected to the output shaft of the transfer motor 241, and a transmission shaft 242 rotatably connected between the transfer fixed frame 22 and the transfer moving frame 23. One end of the transmission shaft 242 also passes through the transfer moving frame 23, and the second coupling is connected to one end of the transmission shaft 242 passing through the transfer moving frame 23. Two driving wheels 243 are also installed on the transmission shaft 242, and the synchronous belts arranged on the transfer fixed frame 22 and the transfer moving frame 23 are respectively wound around one driving wheel 243. The transfer motor 241 can drive the transmission shaft 242 to rotate through the second coupling. When the transmission shaft 242 rotates, the two driving wheels 243 can be driven to rotate. Since a synchronous belt is wound around each driving wheel 243, the two synchronous belts can be driven to rotate synchronously, so as to transfer products.

[0032] In one embodiment, a blocking mechanism 5 and a pressing mechanism 6 are installed on both the transmission fixed frame 22 and the transmission movable frame 23; the blocking mechanism 5 includes a blocking translation cylinder and a blocking rod connected to the blocking translation cylinder; the pressing mechanism 6 includes a pressing lifting cylinder and a pressing plate connected to the pressing lifting cylinder; one end of the pressing plate extends to be arranged above one side of the conveyor belt module 26; first jacks are provided at positions corresponding to the blocking rod on the transmission fixed frame 22 and the transmission movable frame 23, and one end of the blocking rod passes through the first jack and extends to be arranged above the conveyor belt module 26. The blocking translation cylinder can drive the blocking plate to move, thereby stopping the product at a suitable position (detection position). Subsequently, the pressing lifting cylinder can drive the pressing plate to descend, thereby pressing and limiting the product, preventing the product from swaying randomly when the dual-axis translation device 1 drives the product to move, and ensuring the detection accuracy.

[0033] In one embodiment, the X-ray emitting device 4 includes an emitting fixed frame 41, a Z-axis lifting mechanism 42 installed on the emitting fixed frame 41, a Z-axis lifting seat 43 connected to the Z-axis lifting mechanism 42, and an X-ray emitter 44 installed on the Z-axis lifting seat 43. The Z-axis lifting mechanism 42 adopts a motor-screw drive mode and can drive the Z-axis lifting seat 43 to drive the X-ray emitter 44 to lift, realizing detections at different magnifications.
