[0004] In the process of sample extraction and preparation, it is often necessary to process powdered samples and transfer them from one container to another. During transfer, the powdered sample tends to adhere to the bottom or side walls of the container and cannot be completely transferred, requiring manual scraping to improve the sample transfer rate. However, to achieve automated processing, a solution that can meet the powder transfer rate requirements is still lacking. Summary of the Invention

[0016] Figure 1 is a schematic diagram of an automated powder scraping device according to an embodiment of this disclosure. As shown in Figure 1, the horizontal direction is the first direction, and the vertical direction is the second direction.
[0017] In this embodiment of the disclosure, an automated powder scraping device is used to perform a powder scraping operation on the sample. In some embodiments, the sample is a biological sample, a pharmaceutical sample, or a chemical sample. When the sample is a pharmaceutical sample, it may be a Western medicine sample, a traditional Chinese medicine sample, or other drug samples with medicinal effects. For example, traditional Chinese medicine samples include raw medicinal materials, prepared slices of traditional Chinese medicine, proprietary Chinese medicines, semi-finished traditional Chinese medicines, medicinal plants, etc.
[0018] As shown in Figure 1, the automated powder scraping device includes a mounting base 11 and a scraper 12 disposed on the mounting base 11. The scraper 12 includes a transverse blade extending in a first direction and a longitudinal blade extending in a second direction.
[0019] The first pre-compression mechanism supports the mounting base 11 along the first direction. When the longitudinal blade of the scraper 12 contacts the sample container, the first pre-compression mechanism can provide support force in the first direction to the mounting base 11 and the scraper 12, so that the longitudinal blade of the scraper has enough force to scrape the powder. At the same time, the first pre-compression mechanism can also provide buffer for the mounting base 11 and the scraper 12 in the first direction, so that the longitudinal blade is evenly stressed when it contacts the sample container, ensuring that the longitudinal blade of the scraper 12 can effectively scrape the powder.
[0020] The second pre-compression mechanism supports the mounting base 11 along the second direction. When the transverse blade of the scraper 12 contacts the sample container, the second pre-compression mechanism can provide support force in the second direction to the mounting base 11 and the scraper 12, so that the transverse blade of the scraper has enough force to scrape the powder. At the same time, the second pre-compression mechanism can also provide buffering for the mounting base and the scraper 12 in the second direction, so that the transverse blade is evenly stressed when it contacts the sample container, ensuring that the transverse blade of the scraper 12 can effectively scrape the powder.
[0021] In this embodiment, when the transverse and longitudinal blades of the scraper 12 simultaneously contact the sample container—for example, the transverse blade contacts the bottom of the sample container and the longitudinal blade contacts the side wall of the sample container—the first and second pre-compression mechanisms can function simultaneously, providing support and buffering to the longitudinal and transverse blades of the scraper 12, respectively. This ensures that the scraper has sufficient force to scrape powder from both the bottom and side wall of the sample container, and that the force is evenly distributed on both the bottom and side wall of the sample container, thereby effectively reducing powder residue and improving the powder transfer rate.
[0022] In some embodiments, using the automated powder scraping device provided in this disclosure, the powder transfer rate can reach over 95%.
[0023] In some embodiments, as shown in FIG1, the automated powder scraping device further includes a connecting plate 6, and a mounting base 11 is disposed on one side of the connecting plate 6 and coupled to the connecting plate 6; the first pre-compression mechanism and the mounting base 11 are disposed on the same side of the connecting plate 6, and the second pre-compression mechanism and the mounting base 11 are disposed on different sides of the connecting plate 6 respectively.
[0024] In some embodiments, as shown in FIG1, the first pre-compression mechanism includes a guide rail 13 extending along a first direction on the connecting plate 6 and a first elastic component disposed at one end of the guide rail 13; the mounting base 11 is coupled to the guide rail 13 and connected to the first elastic component, the first elastic component being able to provide elastic support, support the mounting base 11 along the first direction and provide cushioning.
[0025] As shown in Figure 1, the guide rail 13 includes a guide rail body and a slider, which can slide on the guide rail body; the first elastic component includes a baffle 7 and a first elastic element, one end of the first elastic element is connected to the baffle 7 and the other end is connected to the mounting base 11.
[0026] In this embodiment, the mounting base 11 and the slider can be an integral structure. For example, the mounting base 11 is provided with a sliding groove that cooperates with the guide rail body, allowing the mounting base 11 to slide laterally on the guide rail body; the mounting base 11 and the slider can also be independent components. This embodiment does not impose any special limitations on this.
[0027] As shown in Figure 1, the mounting base 11 includes a first mounting portion extending along a first direction and a second mounting portion extending along a second direction; the slider is connected to the first mounting portion, and the first elastic member is connected to the second mounting portion.
[0028] As shown in Figure 1, the first elastic component also includes a first guide shaft 9, and the first elastic element includes a first compression spring 10. A through hole is provided on the baffle 7. One end of the first guide shaft 9 passes through the through hole on the baffle 7 and connects to the second mounting portion. The first compression spring 10 is sleeved on the first guide shaft 9. A first limiting portion 8 is provided at the other end of the first guide shaft 9, and the size of the first limiting portion 8 is larger than the size of the through hole on the baffle 7. When the longitudinal blade of the scraper 12 contacts the sample container, the mounting base 11 moves laterally to the right, and the first guide shaft 9 can move laterally to the right in the through hole on the baffle 7, thereby squeezing the first compression spring 10. This compression deformation of the first compression spring 10 provides a lateral leftward support force to the mounting base 11 and the scraper 12. When the mounting base 11 moves laterally to the left, because the size of the first limiting portion 8 is larger than the size of the through hole on the baffle 7, it prevents the first guide shaft 9 from sliding out of the through hole on the baffle 7, limiting the maximum distance the mounting base 11 can move laterally to the left, thus playing a limiting role.
[0029] In this embodiment, the first limiting part 8 and the first guide shaft 9 can be an integral structure; the first limiting part 8 and the first guide shaft 9 can also be independent of each other, for example, assembled together by threaded connection.
[0030] In some embodiments, as shown in FIG1, the second pre-compression mechanism includes a base plate 1 and a second elastic component. The base plate 1 and the mounting base are respectively disposed on different sides of the connecting plate 6. The second elastic component is disposed between the base plate 1 and the connecting plate 6 and is connected to the base plate 1 and the connecting plate 6 respectively. The second elastic component can provide elastic support, support the connecting plate 6 in the second direction and provide cushioning, thereby providing support force and cushioning in the second direction for the mounting base 11 and the scraper 12.
[0031] As shown in Figure 1, the second elastic component includes a second guide shaft 3 and a second compression spring 5. The second guide shaft 3 extends along a second direction and is slidably engaged with the base plate 1 or the connecting plate 6. For example, one end of the second guide shaft 3 is slidably engaged with the base plate 1, allowing it to slide relative to the base plate 1 in a second direction, while the other end is fixedly connected to the connecting plate 6; or one end of the second guide shaft 3 is slidably engaged with the connecting plate 6, allowing it to slide relative to the connecting plate 6 in a second direction, while the other end is fixedly connected to the base plate 1, thereby enabling the base plate 1 and the connecting plate 6 to move relative to each other in a second direction. The second compression spring 5 is disposed between the base plate 1 and the connecting plate 6, and is sleeved on the second guide shaft 3.
[0032] In this embodiment, a plurality of second guide shafts 3 are provided between the base plate 1 and the connecting plate 6, and a second compression spring 5 is sleeved on each second guide shaft 3. The plurality of second guide shafts are evenly distributed on the plane of the base plate 1 or the connecting plate 6, thereby making the force more uniform and the structure more stable.
[0033] In some embodiments, as shown in FIG1, four second guide shafts 3 are provided between the base plate 1 and the connecting plate 6. One end of the second guide shaft 3 is slidably engaged with the base plate 1, and the other end is fixedly connected to the connecting plate 6. The base plate 1 has a through hole, and one end of the second guide shaft 3 passes through the through hole on the base plate 1 and is slidably engaged with the base plate 1, while the other end is fixedly connected to the connecting plate 6. A second limiting part 2 is provided at the end of the second guide shaft 3 away from the connecting plate 6. The size of the second limiting part 2 is larger than the size of the through hole on the base plate 1.
[0034] When the transverse blade of the scraper 12 contacts the sample container, the mounting base 11 moves longitudinally upward. The connecting plate 6 drives the second guide shaft 3 to move longitudinally upward in the through hole on the base plate 1, thereby squeezing the second compression spring 5. The compression spring 5 provides longitudinal downward support force to the mounting base 11 and the scraper 12 through its compression deformation. When the mounting base 11 moves longitudinally downward, since the size of the second limiting part 2 is larger than the size of the through hole on the base plate 1, the second guide shaft 5 can be prevented from sliding out of the through hole on the base plate 1, thus limiting the maximum distance of the mounting base 11 moving longitudinally downward and playing a limiting role.
[0035] As shown in Figure 1, a bearing seat 4 is also provided on the through hole of the base plate 1, and the second guide shaft 3 is set through the bearing seat 4.
[0036] In some embodiments, one end of the second guide shaft 3 is slidably engaged with the connecting plate 6 and can slide relative to the connecting plate 6 in a second direction, while the other end is fixedly connected to the base plate 1. The connecting plate 6 has a through hole, and one end of the second guide shaft 3 passes through the through hole on the connecting plate 6 and is slidably engaged with the connecting plate 6. The other end is fixedly connected to the base plate 1. The second compression spring 5 is sleeved on the second guide shaft 3. A second limiting part 2 is provided at the end of the second guide shaft 3 away from the base plate 1. The size of the second limiting part 2 is larger than the size of the through hole on the connecting plate 6.
[0037] In some embodiments, as shown in FIG1, the automated powder scraping device further includes a connecting part 14 for connecting to an automated mobile device such as a robotic arm, so as to perform automated powder scraping under the drive of the automated mobile device such as the robotic arm.
[0038] Secondly, embodiments of this disclosure provide an automated mobile device, which includes a mobile mechanism and an automated powder scraping device as described in the first aspect of this disclosure, wherein the automated powder scraping device is connected to the mobile mechanism.
[0039] In this embodiment, the automated powder scraping device can be detachably connected to the moving mechanism or fixedly connected to the moving mechanism. This embodiment does not impose any special limitations on this.
[0040] This disclosure provides an automated powder scraping device for automated sample preparation and extraction. It can provide sufficient support and buffering in the first and second directions, so that the scraper is uniformly stressed on the container surface. It can be used for fully automated powder scraping, and can reduce powder residue and improve the transfer rate after scraping, which is beneficial to realizing automated sample extraction and preparation.

In some instances, it will be apparent to those skilled in the art that features, characteristics, and / or elements described in connection with particular embodiments may be used alone, or in combination with features, characteristics, and / or elements described in connection with other embodiments, unless otherwise expressly indicated.
