Abstract
Description
Technical Field
[0001] This utility model relates to the field of material transfer tooling technology, and more specifically, to a sample box for X-ray fluorescence analysis. Background Technology
[0002] In the field of X-ray fluorescence spectroscopy, sample pretreatment typically requires placing molten glass slides into a dedicated analytical container for analysis. Currently, the industry commonly uses a split-type analytical container, mainly composed of a base, an elastic clamping structure, and a top cover. While this split design meets basic loading requirements, it reveals significant shortcomings in automated testing systems.
[0003] Traditional sample box design typically requires removing the lid, placing the sample on a sample tray above a spring-loaded clamping structure, and then closing the lid. The lid is usually screwed on or secured by a spring mechanism when rotated to a designated position. However, automated capping using a robotic arm has a low success rate. If the threads are misaligned or not properly secured, causing the lid to spring open inside the equipment, it can directly lead to mechanical failure and potential damage, severely hindering the efficiency of automated testing lines.
[0004] This technical deficiency directly results in the current X-ray fluorescence spectroscopy detection process, where even though the front-end processes have achieved automated transport, the crucial transfer of the sample fused sheet into the X-ray fluorescence spectrometer still relies on manual operation. Especially in continuous detection operations, operators need to repeat the tray transfer action dozens of times per hour, which not only significantly increases labor costs but also may lead to sample contamination or positioning errors due to operator fatigue.

[0026] Various embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are indicated by the same or similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.
[0027] This utility model provides a sample box for X-ray fluorescence analysis. See [link to relevant documentation]. Figures 1 to 3 The X-ray fluorescence analysis sample box includes: a main outer frame 1, an elastic element, and a support plate 3; wherein, the main outer frame 1 includes a bottom plate 12, a top plate 11, and two support plates 13, the bottom plate 12 and the top plate 11 are both circular plate structures, the two support plates 13 are symmetrically arranged on both sides of the bottom plate 12 and the top plate 11 in the radial direction, and the upper and lower ends of the two support plates 13 are respectively connected to the top plate 11 and the bottom plate 12; two slots 101 are formed on the top plate 11 corresponding to the positions of the two support plates 13, the two slots 101 penetrate the top plate 11 and extend downward by a predetermined distance on the two support plates 13 respectively; the bottom of the elastic element is disposed on the bottom plate 12, the support plate 3 is connected to the top of the elastic element, the upper part of the support plate 3 is used to place a tray box 6, and the elastic element is used to abut the tray box 6 placed on the support plate 3 against the top plate 11.
[0028] The X-ray fluorescence analysis sample cassette provided by this invention is applied in fluorescence docking equipment, specifically for facilitating the transfer of a tray cassette 6 containing a sample fused sheet 7 from a conveyor belt into an X-ray fluorescence spectrometer. Due to the low height of the tray, the gripper mechanism of the transfer device used to directly grasp the tray cassette 6 is prone to slippage, resulting in a low success rate. The X-ray fluorescence analysis sample cassette provided by this invention can fix the tray cassette 6 within it, allowing the gripper mechanism of the transfer device to automatically transfer the tray cassette 6 by gripping the X-ray fluorescence analysis sample cassette, thus automating the transfer of the tray cassette 6.
[0029] Furthermore, the support plate 13 is an arc-shaped plate structure, and the diameter of the outer arc surface of the support plate 13 is consistent with the outer diameter of the top plate 11 and the bottom plate 12. That is, the outer shape of the main body frame 1 formed by the support plate 13, the top plate 11, and the bottom plate 12 is a hollow cylindrical structure, which makes it easier for the gripper mechanism of the material transfer equipment to grip. The diameter of the bearing plate 3 is slightly smaller than the diameter of the inner arc surface of the support plate 13, which not only allows the bearing plate 3 to move smoothly up and down within the main body frame 1, but also ensures that the pressing claws on the external pressing equipment can press against the bearing plate 3 when they move downward through the slot 101 on the main body frame 1, thus applying downward pressure to move the bearing plate 3.
[0030] Furthermore, the elastic element is a tower-shaped spring 2, with its large end positioned on the base plate 12 and its small end connected to the support plate 3. By selecting the tower-shaped spring 2 as the elastic element, a compact layout can be achieved through its variable diameter structure. Within the same installation space, it can provide greater deformation and higher spring force, thereby reducing the overall weight and volume of the X-ray fluorescence analysis sample cassette.
[0031] To ensure a stable connection between the tower spring 2 and the support plate 3, a support member 4 is provided at the bottom of the support plate 3, and the small end of the tower spring 2 is connected to the support member 4. The support member 4 includes a large cylindrical section 41 and a small cylindrical section 42 connected together. The diameters of both the large cylindrical section 41 and the small cylindrical section 42 are smaller than the inner diameter of the small end of the tower spring 2. The large cylindrical section 41 is connected to the bottom of the support plate 3; the small end of the tower spring 2 is fitted onto the support member 4. By configuring the support member 4 as a large cylindrical section 41 and a small cylindrical section 42 connected together, with the large cylindrical section 41 connected to the bottom of the support plate 3, the contact area with the support plate 3 is increased, providing better support for the support plate 3. The small cylindrical section 42 makes it easier for the small end of the tower spring 2 to be fitted onto the support member 4.
[0032] In this embodiment, in order to facilitate the connection between the support member 4 and the bearing plate 3, a screw 31 is provided at the bottom center of the bearing plate 3, and a threaded hole 401 matching the screw 31 is provided at the center of the support member 4. The support member 4 is screwed onto the screw 31 through the threaded hole 401.
[0033] Furthermore, a central hole 111 is provided at the center of the top plate 11. Specifically, the diameter of the central hole 111 is smaller than the diameter of the tray box 6 placed therein, so that the tray box 6 will not fall out of the central hole 111 when it is placed against the top plate 11 by the support plate 3. By providing a central hole 111 at the center of the top plate 11, the sample molten sheet 7 contained in the tray box 6 can be positioned at the central hole 111. After the X-ray fluorescence analysis sample box is transferred to the X-ray fluorescence spectrometer, the sample molten sheet 7 can be analyzed by the X-ray fluorescence spectrometer without unloading the tray box 6. After the analysis is completed, the X-ray fluorescence analysis sample box is removed from the X-ray fluorescence spectrometer, and then the sample molten sheet 7 and the tray box 6 are unloaded. Then, the X-ray fluorescence analysis sample box can receive new sample molten sheets 7 to be tested and the tray box 6 containing the sample molten sheets 7.
[0034] Furthermore, the edge of the top plate 11 is provided with an upper annular retaining edge 112 facing the bottom plate 12, and the edge of the bottom plate 12 is provided with a lower annular retaining edge 122 facing the top plate 11. By providing the upper annular retaining edge 112 on the top plate 11 and the lower annular retaining edge 122 on the bottom plate 12, the bottom of the tray box 6 and the elastic element abutting against the top plate 11 can be circumferentially limited, preventing the tray box 6 or the elastic element from circumferentially dislodging. In addition, the upper annular retaining edge 112 and the lower annular retaining edge 122 can also improve the structural strength of the top plate 11 and the bottom plate 12, respectively, preventing bending deformation when subjected to the elastic force of the elastic element.
[0035] Furthermore, a bottom center hole 121 is provided in the center of the base plate 12. A bottom baffle 5 is placed on the base plate 12, and the bottom of the elastic element abuts against the bottom baffle 5. By providing a bottom center hole 121 in the center of the base plate 12 and placing a bottom baffle 5 on the base plate 12, the installation and removal of the tower-shaped spring 2 are facilitated.
[0036] The X-ray fluorescence analysis sample box provided by this utility model has two slots on the top plate of its main body frame. The slots extend downwards by a preset distance on the support plate after passing through the top plate. By pressing the support plate downwards with an external pressing device, a tray box containing a sample fused sheet can be placed between the support plate and the top plate. After the support plate is released, the elastic element can push the support plate to abut the tray box against the top plate, thereby facilitating the gripper mechanism of the transfer device to pick up the X-ray fluorescence analysis sample box and move the tray box.
