[0002] X-ray fluorescence spectrometer (XRF) is an instrument used to qualitatively and quantitatively analyze the chemical element composition in materials. It is based on the principle of X-ray fluorescence. When a sample is irradiated by high-energy primary X-rays, it will excite the atoms in the sample, causing its internal electrons to jump from one energy level to another. Then, when these excited electrons return to the ground state, they will release characteristic X-rays, namely X-ray fluorescence. By detecting the energy or wavelength of these X-ray fluorescence and measuring its intensity, the elements present in the sample and their content can be determined.

[0003] Before sending the sample into the X-ray fluorescence spectrometer, it is necessary to load the sample. First, place the sample in the sample tray, then flip the sample cup, and then embed the sample tray into the sample cup. Finally, flip the sample cup with the fixed sample back to the right position and send it into the X-ray fluorescence spectrometer. The entire loading process is manually aligned and installed, and the embedding process generally requires alignment. Embedding the sample tray into the sample cup requires repeated operations many times before the sample tray carrying the sample can be embedded in the sample cup.

A sample injection port 15 is provided on one side of the instrument body 1. The sample loading mechanism 2, the sample moving mechanism 3 and the sample injection mechanism 4 are all arranged on the side of the instrument body 1 where the sample injection port 15 is provided. The sample moving mechanism 3 is used to grab a sample bottle. The sample loading mechanism 2 is used to drive a sample tray connected to load a sample. The sample injection mechanism 4 is arranged at the sample injection port 15. The controller is electrically connected to the sample loading mechanism 2, the sample moving mechanism 3 and the sample injection mechanism 4 respectively. When the sample loading mechanism 2 drives the sample tray connected to the sample loaded with the sample, the controller controls the sample moving mechanism 3 to grab and flip the sample bottle, and drives the bottle mouth of the sample bottle to face the sample tray driven and connected by the sample loading mechanism 2, so that the sample loading mechanism 2 drives the sample tray to move toward the sample bottle, and embeds the sample tray into the sample bottle; the controller is also used to control the sample moving mechanism 3 to drive the sample bottle loaded with the sample to flip back to the normal position when the sample tray is embedded in the sample bottle, so that the sample moving mechanism 3 sends the returned sample bottle into the sample injection mechanism 4; the controller is also used to control the sample injection mechanism 4 to send the sample bottle into the instrument body 1 through the sample injection port 15 for detection.

[0037] Specifically, after the sample bottle is sent into the instrument body 1, the robot in the instrument body 1 grabs the sample bottle and sends it to each sample bottle placement position, or the robot directly sends the sample bottle to the detection position. The original robot, placement area and detection position in the instrument body 1 belong to the more common technical solutions, so they are not described one by one here.

[0038] The sample loading mechanism 2 comprises a base 21, a first lifter 22 and a first connecting seat 23. The base 21 is arranged on a side of the instrument body 1 where the sample inlet 15 is arranged, and the sample moving mechanism 3 is located above the base 21; the first lifter 22 is arranged on a side of the base 21 facing the sample moving mechanism 3; the first connecting seat 23 is arranged on a side of the first lifter 22 away from the base 21, and the output end of the first lifter 22 is driven to connect to the first connecting seat 23, and the first lifter 22 is used to drive the first connecting seat 23 to move vertically so that the first connecting seat 23 is close to the sample moving mechanism 3; a protrusion 24 is arranged on a side of the first connecting seat 23 away from the first lifter 22, and the protrusion 24 is used to be inserted into the groove at the bottom of the sample tray so that the protrusion 24 supports the sample tray to be set horizontally; a controller is electrically connected to the first lifter 22, and the controller is used to control the first lifter 22 to drive the protrusion 24 through the first connecting seat 23 when the protrusion 24 supports the sample tray loaded with the sample to be set horizontally, so that the protrusion 24 drives the sample tray to be close to the sample moving mechanism 3. The first lifter 22 is relatively fixed to the outside of the instrument body 1 through the base 21, and drives the sample holder to rise and fall vertically through the protrusion 24 of the first connecting column, so that the first lifter 22 and the sample transfer mechanism 3 cooperate to complete the embedding of the sample holder into the sample bottle, realizing the automatic installation of the sample.

[0039] Specifically, a second servo motor 25 is arranged on the side of the base 21 facing the first lifter 22, and the second servo motor 25 is driven to be connected to the first lifter 22.

When the sample bottle and the sample tray are aligned, the first lifter 22 is controlled to embed the sample tray into the sample bottle; when the sample bottle and the sample tray are not aligned, the second servo motor 25 is controlled to drive the sample tray to rotate horizontally until the sample bottle and the sample tray are aligned, and then the first lifter 22 is controlled to embed the sample tray into the sample bottle. Through the cooperation of the camera 11 and the second servo motor 25, the automatic alignment of the sample tray and the sample is realized, which further simplifies the operation and improves the loading efficiency.

[0040] Specifically, the first characteristic area is the slot hole on the side wall of the sample bottle; the second characteristic area is the half slot on the top side of the sample holder.

[0041] Specifically, the controller is also used to determine the position of the mouth of the sample bottle according to the first image. When the mouth of the sample bottle is facing downward, the first characteristic area of ​​the sample bottle is identified according to the first image, and the second characteristic area of ​​the sample tray is identified according to the second image. When the mouth of the sample bottle is facing upward, the sample transfer mechanism 3 is controlled to flip the sample bottle, and then the first characteristic area of ​​the sample bottle is identified according to the first image, and the second characteristic area of ​​the sample tray is identified according to the second image. Automatic flipping of the sample bottle is achieved, and the steps for the staff to send the sample bottle into the sample transfer mechanism 3 are further simplified.

[0042] The sample moving mechanism 3 includes a horizontal moving module 5, a clamping module 6, a second connecting seat 31 and two flipping modules 7.

The fixed space 32 is used to accommodate the sample bottle; the controller is electrically connected to the horizontal moving module 5, the clamping module 6 and the two flipping modules 7 respectively, and the controller is used to control the clamping module 6 to drive the two flipping modules 7 to move closer, so that the two flipping modules 7 clamp the sample bottle and fix it in the fixed space 32; the controller is also used to control the two flipping modules 7 to drive the sample bottle to flip after the two flipping modules 7 clamp and fix the sample bottle, so that the bottle mouth of the sample bottle is aligned with the sample tray; the controller is used to control the horizontal moving module 5 and the two flipping modules 7 respectively after the sample tray is embedded in the sample bottle, so that the flipped sample bottle is sent into the sample injection mechanism 4.

[0043] The horizontal moving module 5 includes a first track 51, a first electric-controlled slide 52 and a third lifter 53. The first track 51 is arranged on the side of the instrument body 1 where the injection port 15 is arranged. The first track 51 is located above the base 21. The first electric-controlled slide 52 is located on the side of the first track 51 facing the base 21. The first electric-controlled slide 52 is slidably connected to the first track 51.

The controller is electrically connected to the first electric-controlled slide 52 and the third lifter 53 respectively. The controller is used to control the first electric-controlled slide 52 to drive the clamping module to slide along the first track 51, so that the third lifter 53 cooperates with the first electric-controlled slide 52 to deliver the sample bottle into the injection mechanism 4. The cooperation between the first track 51 and the second electric-controlled slide 13 enables the clamping module 6 and the two flip modules 7 to move freely between the base 21 and the injection mechanism 4.

[0044] Specifically, the first track 51 is arranged horizontally.

A certain amount of pressure is required for the sample holder to embed into the sample bottle. The cooperation of the second lifter 64 and the limit plate 65 can limit the sample bottle and avoid separation of the sample and the two flipping mechanisms during the embedding process.

[0047] The flip module 7 includes a third connection seat 71, a first servo motor 72 and a pressing plate 73.

The positioning groove 43 is used to accommodate the sample bottle loaded with the sample; the controller is electrically connected to the linear motor 41. When the sample transfer mechanism 3 drives the sample bottle loaded with the sample to approach the sample injection port 15, the controller controls the linear motor 41 to drive the positioning plate 42 to move to the end away from the instrument body 1, so that the sample transfer mechanism 3 can send the sample bottle loaded with the sample into the positioning groove 43; the controller is also used to control the linear motor 41 to drive the positioning plate 42 after the sample bottle loaded with the sample is sent into the positioning groove 43, so as to send the sample bottle loaded with the sample into the instrument body 1 through the sample injection port 15.
