[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] A fluorescence detection device, such as Figure 2 , Figure 3 As shown, the system includes a support assembly 1 and an industrial control computer 3. A tray 9 for holding a material box 91 is provided on the top of the support assembly 1. A three-axis gantry gripper 4, a linear conveyor assembly 5, a lifting device 6, and a detection assembly 7 are installed on the top of the support assembly 1. The rear end of the linear conveyor assembly 5 extends to the bottom of the detection assembly 7. The range of motion of the three-axis gantry gripper 4 covers the front end of the tray 9 and the linear conveyor assembly 5. A laser rangefinder 8 is provided on the side of the lifting device 6 near the linear conveyor assembly 5. The laser rangefinder 8 is connected to the lifting device 6 through a controller and points downwards towards the linear conveyor assembly 5. The three-axis gantry gripper 4 and the linear conveyor assembly 5 are controlled by the controller through programming. The detection assembly 7 is connected to the industrial control computer 3.

[0020] The working principle of fluorescence detection is as follows: The sample is placed in the material box 91. Multiple material boxes 91 are placed on the surface of the tray 9 according to the set arrangement points. The three-axis gantry gripper 4 picks up the material boxes 91 one by one and places them on the surface of the linear conveyor assembly 5. The linear conveyor assembly 5 conveys the material boxes 91 towards the detection assembly 7. During the conveying process, the height of the sample is detected by the laser rangefinder 8 and the detection information is fed back to the controller. The controller controls the lifting device 6 to adjust the height of the detection assembly 7 to ensure that the distance from the upper edge of the material to the lower edge of the detection assembly 7 is 2mm. The fluorescence detection of the sample is performed by the detection assembly 7. The detection information is transmitted to the industrial control all-in-one computer 3. After subsequent software and algorithm processing, the energy spectrum information of the detected material is obtained. After testing, the sample is transported in reverse by the linear conveyor assembly 5 to the front end. The three-axis gantry gripper 4 then places the tested material box 91 back onto the surface of the tray 9. The three-axis gantry gripper 4 then removes an untested material box 91 and places it on the surface of the linear conveyor assembly 5, and the above testing process is repeated.

[0021] The structure of the three-axis gantry gripper 4 is as follows: like Figure 2 As shown, the three-axis gantry gripping device 4 includes an X-axis linear propulsion assembly, a Y-axis linear propulsion assembly, a Z-axis linear propulsion assembly, and a pneumatic opening and closing gripper. The X-axis linear propulsion assembly, the Y-axis linear propulsion assembly, and the Z-axis linear propulsion assembly have the same structure, which are all existing linear screw feed assemblies. Specifically, the structure consists of a carriage, a screw, and a motor that drives the screw. A slide block is slidably mounted on the surface of the carriage, and the screw is threadedly connected to the slide block to drive the slide block to move linearly. The Y-axis linear propulsion assembly connects to the slides of two sets of X-axis linear propulsion assemblies, and the Z-axis linear propulsion assembly connects to the slides of the Y-axis linear propulsion assembly. The pneumatic opening and closing gripper is an existing structure, and the pneumatic opening and closing gripper is connected to the slide of the Z-axis linear propulsion assembly. The X-axis linear propulsion assembly, Y-axis linear propulsion assembly, and Z-axis linear propulsion assembly work together to drive the three-dimensional movement of the pneumatic opening and closing gripper, so that the pneumatic opening and closing gripper can hold and transfer the material container 91.

[0022] The structure of the linear conveyor assembly 5 is as follows: like Figure 3 As shown, the linear conveying assembly 5 includes a linear support shell 51, and a transmission belt 52 is installed along the linear support shell 51. The transmission belt 52 has the following specific structure: two belt rollers are fitted with a toothed belt body, one of the belt rollers of the transmission belt 52 is connected to the output shaft of the servo motor 53, and a movable seat 54 is slidably set along the linear support shell 51. The movable seat 54 is connected to the belt body of the transmission belt 52. The servo motor 53 drives the transmission belt 52 to rotate, causing the transmission belt 52 to drive the movable seat 54 to move linearly along the linear support shell 51. The movable seat 54 is used to support the material box 91 to move.

[0023] The lifting device 6 has the following structure: like Figure 3 As shown, the lifting device 6 includes a base 61, on which a platform 63 is vertically slidably mounted via a slide rail and a slider. A vertical cylinder 62 is mounted on the top of the base 61, and the telescopic end of the vertical cylinder 62 is connected to the platform 63. The detection component 7 is mounted on the surface of the platform 63. The vertical cylinder 62 drives the stage 63 to move the detection component 7 up and down, which is used to adjust the height of the detection component 7 relative to the sample.

[0024] The structure of detection component 7 is as follows: like Figure 4 As shown, the detection component 7 includes a mounting base 73, which is fixed on the surface of the stage 63. A V-shaped channel 74 is opened in the mounting base 73, penetrating the bottom surface. An X-ray source 71 and a detector 72 are mounted in a V-shape on the surface of the mounting base 73. The working ends of the X-ray source 71 and the detector 72 are aligned with the V-shaped channel 74. X-ray source 71 emits X-rays to irradiate the sample to excite the sample’s characteristic X-ray fluorescence. Detector 72 is used to receive the characteristic X-ray fluorescence and transmit it to industrial control computer 3. Through subsequent software and algorithm processing, the energy spectrum information of the detected material is obtained.

[0025] A transparent partition 75 is encapsulated at the bottom of the V-shaped channel 74 to shield and protect the working surfaces of the X-ray source 71 and the detector 72.

[0026] like Figure 1As shown, a protective cover 2 is provided on the top of the support assembly 1. The protective cover 2 is used to close the working parts on the top of the support assembly 1, providing a relatively sealed environment for the inspection work. The surface of the protective cover 2 has a window, which is sealed by a rotatable cover plate 21. The window can be opened and closed by the cover plate 21 to facilitate the loading and unloading of the material box 91 and equipment maintenance.

[0027] Four sets of universal self-locking wheels 11 are installed at the bottom of the bracket assembly 1 for easy movement of equipment.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
