[0047] like Figure 3 , Figure 6 and Fig.10 As shown, an automatic positioning device for an X-ray source of an X-ray machine of the present invention, the connecting component 10 includes an electric push rod 1001 installed on a workbench 1, a connecting plate 1002 is provided at the output end of the electric push rod 1001, a transmission tube 1003 is connected to a bearing on the connecting plate 1002, both ends of the transmission tube 1003 are fixedly sleeved with a snap-on gear 2 1004 meshing with an inner gear ring 1 805 or an inner gear ring 2 906, and an inner wall of the transmission tube 1003 is provided with an inner gear ring 3 1005 meshing with the snap-on gear 1 703.

[0048] Working principle: when testing the product, the product is placed on the conveyor belt 203, and the electric push rod 1001 is started, forcing the output end of the electric push rod 1001 to drive the connecting plate 1002 to move, the connecting plate 1002 drives the transmission tube 1003 to move, and the transmission tube 1003 drives the clamping gear 2 1004 to move, forcing the clamping gear 2 1004 on one side to separate from the inner gear ring 1 805, and the clamping gear 2 1004 on the other side to mesh with the inner gear ring 2 906, and the clamping gear 1 703 and the inner gear ring 3 1005 are always in a meshing state. At this time, the rotating rod 702 is connected with the rotating tube 2 905 and the sleeve 2 902 to form a whole. At this time, the electromagnet is energized, so that the electromagnet and the magnet block have an attraction effect, which limits the free movement of the electromagnet, that is, limits the free movement of the arc slider 402, and prevents the arc slider 402 from sliding freely under the action of gravity;

[0049] The motor 701 is started, and the output shaft of the motor 701 rotates to drive the rotating rod 702 to rotate. The rotating rod 702 drives the engaging gear 1 703 to rotate, and drives the inner gear ring 3 1005 to rotate, forcing the transmission tube 1003 to rotate. The transmission tube 1003 drives the engaging gear 2 1004 to rotate. Since one of the inner gear rings 2 906 is meshed with the engaging gear 2 1004, the rotating tube 2 905 is forced to rotate. The rotating tube 2 905 rotates to drive the sleeve 2 902 to rotate. The sleeve 2 902 rotates to drive the active bevel gear 903 to rotate, and forces the driven bevel gear 904 to rotate to drive the shaft 201 to rotate. The shaft 201 drives the rotating roller 202 to rotate. Under the transmission action of the conveyor belt 203, the multiple rotating rollers 202 are forced to rotate, so that the rotating rollers 202 and the conveyor belt 203 move synchronously to transport the product, until the conveyor belt 203 transports the product to the position below the X-ray machine body 501 and the strip X-ray port 502.

[0050] Position the product, close the X-ray machine body 501, turn on the camera 604 and the laser generator 602, start the electric push rod 1001 in reverse, and force the output end of the electric push rod 1001 to drive the connecting plate 1002 to move, the connecting plate 1002 drives the transmission tube 1003 to move, and the transmission tube 1003 drives the clamping gear 2 1004 to move, forcing the clamping gear 2 1004 on one side to mesh with the inner gear ring 1 805, and the clamping gear 2 1004 on the other side to separate from the inner gear ring 2 906, and the clamping gear 1 703 and the inner gear ring 3 1005 are always in a meshing state. At this time, the rotating rod 702 is connected with the rotating tube 1 804 and the sleeve 1 802 to form a whole. At this time, the electromagnet is powered off, so that the electromagnet and the magnet block lose their attraction, so that the electromagnet moves freely, that is, the arc-shaped slider 402 moves freely;

[0051] Start the motor 701, the output shaft of the motor 701 rotates to drive the rotating rod 702 to rotate, the rotating rod 702 drives the engaging gear 1 703 to rotate, and drives the inner gear ring 3 1005 to rotate, forcing the transmission tube 1003 to rotate, and the transmission tube 1003 drives the engaging gear 2 1004 to rotate. Since the engaging gear 2 1004 is meshed with the inner gear ring 1 805, the rotating tube 1 804 is forced to rotate, and the rotation of the rotating tube 1 804 drives the sleeve 1 802 to rotate, and the rotation of the sleeve 1 802 drives the rotating gear 803 to rotate, and the rotation of the rotating gear 803 drives the annular gear 405 to rotate, and the annular gear 405 drives the rotating gear 404 to rotate. Under the action of the annular gear 405 and the limiting rack 303, the rotating gear 404 is forced to rotate around the circular track 401. The rotating gear 404 drives the support plate 403 to rotate, and the support plate 403 drives the arc slider 402 to move on the circular track 401. The arc slider 402 drives the X-ray machine body 501 and the strip X-ray port 502 and the laser generator 602, the strip laser head 603 and the camera 604 to rotate around the circular track 401. The laser generator 602 is started. Under the action of the strip laser head 603, the laser is forced to generate a strip laser. The strip laser will locate the edge of the product. At the same time, the camera 604 takes a picture of the position where the strip laser is generated, and transmits it to the control system for analysis and feedback. Under the rotation of the arc slider 402, until the strip laser moves to the contact edge of the product and the conveyor belt 203, the positioning of the edge position of the product is completed;

[0052] During the inspection, similarly, the motor 701 is started continuously, and under the action of the rotating assembly 8 and the rotating assembly 4, the arc slider 402, the X-ray machine body 501, the strip X-ray port 502, the laser generator 602, the strip laser head 603 and the camera 604 are driven to rotate around the circular track 401, and at the same time, the X-ray machine body 501 is opened, and the laser generator 602 is closed, and the X-ray machine body 501 is forced to perform a comprehensive inspection of the product through the strip X-ray port 502 until the X-ray source moves to the other side of the product, and the laser generator 602 is turned on, and the strip laser head 603 generates a strip laser and moves to the other side edge of the product and the conveyor belt 203, completing the inspection of the product, determining the inspection trajectory of the X-ray machine body 501, and when the X-ray machine body 501 and the strip X-ray port 502 move from one side to the other side, the overall inspection of the product is realized. After completing the conveying and inspection of one product, the above steps are repeated to complete the continuity inspection of all products;

[0053] When it comes to products with the same specifications and sizes, when the detection trajectory of the X-ray machine body 501 is determined, repeated actions can be performed on multiple products, thereby quickly inspecting the products; when it comes to products with different specifications, the detection trajectory of the X-ray machine body 501 cannot be determined at this time, and the above steps can be repeated to implement multiple adjustments to the X-ray machine body 501, thereby completing the inspection of the entire product, so that the device can meet the inspection of products with the same specifications as well as the inspection of different and irregular products, thereby improving the adaptability of the device.

[0054] The setting of the conveying component 2 can realize the conveying capacity of the product, convey the product to the bottom of the X-ray machine body 501, realize the detection of the product by the X-ray machine body 501, and realize the loading and unloading of the product, thereby improving the flexibility and practicality of the device; the setting of the supporting component 3 can realize the limiting effect on the rotating gear 404, realize the rotation effect of the rotating gear 404, thereby realize the rotation movement of the X-ray machine body 501, and realize the comprehensive detection of the product by the X-ray machine body 501; the setting of the rotating component 4 can realize the rotation effect on the arc slider 402, thereby making the X-ray machine body 501 rotate around the axis of the circular track 401. During transportation, the electromagnet is energized to realize the attraction effect on the magnet stone. Thereby, the magnet stone limits the free movement of the electromagnet, and can limit the arc slider 402 when the X-ray machine body 501 rotates, thereby preventing the arc slider 402 from sliding freely and improving the stability of the device; the setting of the detection component 5 can enable the X-ray machine body 501 to generate an X-ray source, thereby performing a comprehensive detection of the product, which has the characteristics of non-invasiveness and intuitiveness. The setting of the strip X-ray port 502 can adapt to the width of the product. When encountering an object with a larger width, it can be replaced according to needs, thereby increasing the detection range of the X-ray machine body 501 and improving the detection efficiency; the setting of the positioning component 6 can automatically locate the edge of the product in contact with the conveyor belt 203, thereby realizing the confirmation of the specifications of the product.
