[0002] X-ray fluorescence spectrometers are widely used in material composition analysis and elemental detection. Automated sample feeding devices, as supporting equipment, are used to automatically transfer and load / unload samples, improving the automation and efficiency of detection. However, existing automated sample feeding devices for X-ray fluorescence spectrometers have shortcomings: poor sample positioning accuracy during feeding, easily affecting detection results due to positional deviations; limited flexibility in the device's mechanical structure, resulting in poor adaptability to loading and unloading samples of different sizes and shapes; and inadequate installation and wiring in some devices, leading to difficulties in later maintenance and cable management, ultimately failing to meet the needs for efficient, accurate, and convenient detection assistance. Utility Model Content

An loading and unloading component 3 is provided in the middle of the installation component 1 for grabbing, placing and positioning the sample, ensuring that the sample is accurately delivered to the detection position.

[0021] Mounting component 1 includes a rectangular mounting frame 11, which serves as the basic support structure for the device and provides a mounting carrier for the sample feeding component 2 and the loading / unloading component 3. Each end of the rectangular mounting frame 11 is fixedly connected to a mounting base 13 on both the front and rear sides for fixing the entire device onto the X-ray fluorescence spectrometer or related worktable. The mounting base 13 has a waist-shaped hole 14 between the center of the upper and lower side walls to facilitate adjustment of the installation position according to actual installation needs and enhance the adaptability of the installation. The bottom of the rectangular mounting frame 11 has grooves 12 on both sides to facilitate the passage of connecting wires of the X-ray fluorescence spectrometer equipment components inside the rectangular mounting frame 11, which facilitates cable management and layout, improves the neatness of the device and the convenience of later maintenance.

[0022] The sample delivery component 2 includes two first electric guide rails 21 fixedly connected in a symmetrical manner at one end of a rectangular mounting frame 11, providing a linear motion track for sample delivery. A first electric slider 22 is slidably mounted on the outer side of the first electric guide rail 21, which can slide along the first electric guide rail 21. A mounting platform 23 is fixedly connected to the top of the first electric slider 22 for placing the sample to be tested. The top of the mounting platform 23 is provided with anti-slip texture to increase the friction when the sample is placed and prevent the sample from sliding. Mounting holes 24 are opened between the upper and lower side walls at the four corners of the mounting platform 23, which can be used with tooling fixtures to fix the sample, adapting to the sample delivery needs of samples of different shapes and specifications.

[0023] The loading and unloading assembly 3 includes a reduction drive 31 fixedly mounted at the middle of both ends of a rectangular mounting frame 11, providing power output to drive the connecting rod 32 to rotate. The rotating ends of the two reduction drives 31 on opposite sides are fixedly connected to the connecting rod 32 for power transmission. A three-dimensional adjustment assembly, an electric gripper 36, and a positioner 39 are arranged between the two connecting rods 32. The three-dimensional adjustment assembly includes a second electric guide rail 33 fixedly mounted on the opposite ends of the two connecting rods 32. A second electric slider is slidably mounted on the outer side of the second electric guide rail 33. The two second electric sliders are fixedly connected to the same third electric guide rail 34 at opposite ends. A third electric guide rail 34 is slidably mounted on the outer side of the third electric guide rail 34. The electric slider 35, through the cooperation of the second electric guide rail 33 and the third electric guide rail 34, enables the electric gripper 36 to adjust its position in three-dimensional space, improving the flexibility and accuracy of loading and unloading. The electric gripper 36 is fixedly installed at the bottom of the third electric slider 35 for gripping and releasing samples. The inner wall of the gripper 36 is provided with multiple anti-slip grooves 37 in an array to increase the friction when gripping samples and ensure gripping stability. A connecting frame 38 is fixedly installed on the outside of the positioner 39. The connecting frame 38 is fixedly connected to one side of the third electric slider 35. Before and after the electric gripper 36 grips the sample, the positioner 39 can accurately position the sample to ensure accurate loading and unloading.

[0024] The three-dimensional adjustment component, through the coordinated movement of the second electric guide rail 33 and the third electric guide rail 34, can realize the position adjustment of the electric gripper 36 in the X and Y axis directions. Combined with the angle adjustment achieved by the reduction drive 31 driving the connecting rod 32 to rotate, it can cover the sample delivery area in all directions and accurately grasp and place the sample.

[0025] The electric gripper 36 can be set with appropriate gripping force and opening degree according to the shape and size of the sample via the control console, thereby improving its adaptability to different samples.

[0026] Positioner 39 uses high-precision sensors, such as laser displacement sensors and vision sensors, which can be selected according to actual needs. It detects sample position information in real time and feeds it back to the control system for position adjustment to ensure loading and unloading accuracy.

[0027] The working principle of this utility model is as follows: The sample to be tested is placed on the mounting platform 23 of the sample delivery component 2. If the sample is prone to sliding or has a special shape, the mounting holes 24 on the mounting platform 23 can be used with tooling fixtures to fix the sample. The reduction drive 31 is started, driving the connecting rod 32 to rotate. At the same time, the second electric guide rail 33 and the third electric guide rail 34 move together to adjust the position of the electric gripper 36, so that the electric gripper 36 moves to a suitable position above the sample. The positioner 39 detects the sample position and provides feedback to assist the electric gripper 36 in accurately grasping the sample. After the electric gripper 36 grasps the sample, the three-dimensional adjustment component adjusts the position again and places the sample in the detection area of ​​the X-ray fluorescence spectrometer to complete the loading. The first electric guide rail 21 drives the first electric slider 22 to slide, driving the mounting platform 23 to move. If multiple samples are to be tested in sequence, they can be moved through the mounting platform 23. Mounting hole 24, in conjunction with tooling, enables continuous multi-sample delivery. For samples in the testing area that have already been loaded, during the testing process, the sample delivery component 2, in conjunction with the loading / unloading component 3, can remove the completed sample or deliver a new sample, according to the testing process requirements. After the sample testing is completed, the three-dimensional adjustment component drives the electric gripper 36 to move above the sample in the testing area. The electric gripper 36 picks up the sample, and then the position is adjusted by the three-dimensional adjustment component to place the sample on the mounting platform 23 or other designated unloading position to complete the unloading. Compared with traditional sample delivery devices, this device improves the flexibility and accuracy of loading / unloading through its three-dimensional adjustment and precise positioning structure. The optimized installation and wiring design enhances the practicality and maintenance convenience of the device, enabling it to efficiently adapt to the testing requirements of X-ray fluorescence spectrometers and improve the automation and efficiency of the testing process.

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.
