Description

Technical Field

[0001] The utility model relates to the technical field of X-ray fluorescence measurement, and particularly relates to an X-ray fluorescence measurement tray for automatic measurement. Background Technique

[0002] X-ray fluorescence measurement, also known as X-ray fluorescence analysis, refers to a method of using primary X-ray photons or other microscopic particles to excite atoms in a sample to be measured, causing them to emit fluorescence, i.e., secondary X-rays, for material composition analysis and chemical form research. When measuring and analyzing a sample to be measured, an X-ray fluorescence measuring instrument is generally used.

[0003] When performing X-ray fluorescence measurement on a sample to be measured, an operator needs to open the baffle of the X-ray fluorescence measuring instrument, place the sample to be measured on the tray at the measurement port of the X-ray fluorescence measuring instrument, and then close the baffle. Only one sample to be measured can be placed for measurement and analysis each time, resulting in low efficiency.

[0004] Based on this, an X-ray fluorescence measurement tray for automatic measurement is now provided, which can eliminate the drawbacks of existing devices. Content of the Utility Model

Detailed implementation mode

[0023] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0024] In one embodiment, as Figures 1-4 shown, an X-ray fluorescence measurement tray for automatic measurement includes a placement tray 401.

[0025] In this embodiment, six placement grooves 404 for placing samples to be measured are provided on the upper surface of the placement tray 401. A placement tray connecting block 402 is provided on the lower surface of the placement tray 401. The lower end of the placement tray connecting block 402 is connected to the second slider 201 through a plug-in structure. The second slider 201 is arranged on the installation tabletop 101 through a moving mechanism. The sample material to be measured and analyzed is placed in the placement groove 404 on the placement tray 401. The moving mechanism controls the placement tray 401 to move horizontally through the second slider 201 and the placement tray connecting block 402 combined with the second slider 201, and moves the placement groove 404 to the measurement head of the X-ray fluorescence measuring instrument one by one, so as to realize the measurement and analysis of multiple samples to be measured placed at one time.

[0026] In one embodiment, as Figure 3 and Figure 4 shown, the plug-in structure includes a second slider 201 and a placement tray connecting block 402 connected to the lower surface of the placement tray 401. A placement tray mounting groove 301 matching the shape of the placement tray connecting block 402 is provided on the upper surface of the second slider 201. Telescopic cavities 303 communicating with the placement tray mounting groove 301 are respectively provided on the left and right side walls of the placement tray mounting groove 301 of the second slider 201. A telescopic limiting block 302 is slidably arranged in the telescopic cavity 303. One end of the telescopic limiting block 302 far away from the placement tray mounting groove 301 is connected to one end of a spring 304, and the other end of the spring 304 contacts a sealing plate 305. The sealing plate 305 is connected to the outer side wall of the second slider 201.

[0027] In one embodiment, as Figure 1 and Figure 2As shown in the figure, the moving mechanism includes a first slider 102 slidably connected to the lower end of the second slider 201. A second fixing block 205 is vertically provided at the rear end of the upper surface of the first slider 102, and a second motor mounting block 204 is vertically provided at the front end of the upper surface of the first slider 102. A second motor 203 is provided on the front end face of the second motor mounting block 204. The second slider 201 penetrates through in the front-rear direction and is threadedly connected to a second lead screw 202. One end of the second lead screw 202 is rotatably connected to the second fixing block 205, and the power output shaft of the second motor 203 penetrates through the second motor mounting block 204 and is connected to the other end of the second lead screw 202. The first slider 102 is slidably connected to the mounting table 101. The first slider 102 penetrates through in the left-right direction and is threadedly connected to a first lead screw 103. One end of the first lead screw 103 is rotatably connected to a first fixing block 105, and the first fixing block 105 is fixed on the mounting table 101. The other end of the first lead screw 103 is connected to the power output shaft of a first motor 104, and the first motor 104 is fixed on the mounting table 101.

[0028] In one embodiment, as Figure 4 shown, the part of the telescopic limiting block 302 exposed inside the placement plate mounting groove 301 is hemispherical. When disassembling and assembling the placement plate 401, the telescopic limiting block 302 can be retracted into the telescopic cavity 303 when the placement plate connecting block 402 slides up or down in the placement plate mounting groove 301.

[0029] In one embodiment, as Figure 3 and 4 shown, a limiting groove 403 is provided on the side surface of the placement plate connecting block 402 corresponding to the position of the telescopic limiting block 302, so that the placement plate connecting block 402 is more stable when inserted into the placement plate mounting groove 301.

[0030] In one embodiment, as Figure 4 shown, the limiting groove 403 is a spherical groove that matches the part of the telescopic limiting block 302 exposed inside the placement plate mounting groove 301.

[0031] In one embodiment, as Figure 1 and Figure 2 shown, the sliding contact surface between the first slider 102 and the mounting table 101 is smooth, and the sliding contact surface between the second slider 201 and the first slider 102 is smooth, reducing friction, reducing the load on the motor, and increasing the service life.

[0032] In one embodiment, as Figure 4 shown, the spring 304 is always in a compressed state. The spring 304 applies a sufficient force to the placement plate connecting block 402 through the telescopic limiting block 302 to stably insert the placement plate 401 on the second slider 201.

[0033] The above embodiments disclose an X-ray fluorescence measurement tray for automatic measurement. When performing X-ray fluorescence measurement and analysis on a sample to be measured, first place the sample to be measured in the placement groove 404 on the placement plate 401. The second motor 203 drives the second slider 201 to slide on the first slider 102 through the second lead screw 202, and the first motor 104 drives the first slider 102 to slide on the upper surface of the installation table 101 through the first lead screw 103, so as to realize the movement of the placement plate 401 in any direction within the horizontal plane. By controlling the operation of the first motor 104 and the second motor 203 through a preset program, the placement grooves 404 on the placement plate 401 can be made to face the measurement head of the X-ray fluorescence measuring instrument one by one for X-ray fluorescence measurement and analysis. When the placement plate 401 needs to be cleaned, first move the placement plate 401 away from directly below the measurement head of the X-ray fluorescence measuring instrument, and then lift the placement plate 401 to pull out the placement plate connection block 402 on the lower surface of the placement plate 401 from the placement plate installation groove 301, so as to remove the placement plate 401 for cleaning.

[0034] As described above, the above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
