For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0036] Please refer to Figure 1 , is a sample carrying assembly 1 according to an embodiment of the present application, the sample carrying assembly 1 includes a support frame 11 and a carrying member 13 arranged on the support frame 11.

[0037] The support frame 11 is the main supporting structure of the entire sample support assembly 1 and is generally made of a magnetic metal material, or a magnetic metal material is provided on the support frame 11. Magnetic metal materials refer to metals or alloys that can generate magnetism under the action of a magnetic field. For example, iron, steel, and their alloys. The magnetic metal material allows the support frame 11 to be tightly fixed to the sample carrier using magnetic adsorption technology.

[0038] The carrier 13 is a sample carrying platform, and is usually made of glass or other transparent materials. The carrier 13 is disposed on the support frame 11 and fixed to the stage of the sample processing device through the support frame 11.

[0039] Specifically, refer to Figure 1 and 2 The support frame 11 has a receiving groove 110 on its surface for accommodating the carrier 13. Two opposing sidewalls of the receiving groove 110 each have a limiting groove 111 formed therein, with a slideway formed within the limiting groove 111. The two side edges of the carrier 13 slide along the slideways on either side of the receiving groove 110 to insert the carrier 13 into the limiting groove 111. This ensures that the carrier 13 can be accurately and stably inserted and secured to the support frame 11.

[0040] In order to facilitate the installation and disassembly of the supporting member 13, after the supporting member 13 is inserted into the limiting groove 111, a certain amount of movable space is usually left between the supporting member 13 and the limiting groove 111, so that the supporting member 13 has a certain amount of movement during the installation and disassembly process, which is convenient for operation.

[0041] However, the aforementioned movable space can easily lead to an unstable connection between the carrier 13 and the support frame 11. Therefore, an elastic member 12 is provided between the carrier 13 and the support frame 11. The elastic member 12 can compensate for the movable space between the support frame 11 and the carrier 13 through its elastic force, thereby improving the stability of the connection between the two.

[0042] Specifically, refer to Figure 1 and 3 The elastic member 12 is installed inside the receiving groove 110, between the carrier 13 and the support frame 11. One end of the elastic member 12 abuts the bottom wall of the receiving groove 110, and the other end abuts the carrier 13. The elastic member 12 uses its elastic force to push the carrier 13 toward the limiting surface 1110 of the limiting groove 111, thereby ensuring that the carrier 13 is tightly against the limiting surface 1110, improving the stability of the connection between the carrier 13 and the support frame 11.

[0043] The elastic member 12 may be a spring, an elastic buckle, or other elastic materials or components. This application does not impose any specific restrictions, as long as the elastic member 12 can provide sufficient elastic force to stably connect the carrier 13 to the support frame 11.

[0044] The sample carrying assembly 1 provided in the present application solves the problem of loosening of the carrying member 13 due to loose fixation by arranging an elastic member 12 between the carrying member 13 and the support frame 11, thereby improving the stability of the connection between the carrying member 13 and the support frame 11.

[0045] In one embodiment, reference Figure 1 and 2 The receiving groove 110 extends along the first direction and is in communication with the first side surface 115 of the support frame 11. In other words, the receiving groove 110 is provided with an opening on one side of the first side surface 115, which provides a convenient insertion path for the carrier 13. Through this opening, the carrier 13 can be easily inserted into or removed from the limiting groove 111, thereby simplifying and facilitating the assembly process between the carrier 13 and the support frame 11.

[0046] In one embodiment, a groove 112 is formed at the bottom of the receiving groove 110. The elastic member 12 is preferably an elastic plate, which is fixed in the groove 112. The groove 112 provides a suitable accommodation space for the elastic plate, preventing the elastic plate from moving or falling off, and also facilitating the installation process of the elastic plate.

[0047] Furthermore, the elastic plate can be fixed in the groove 112 by means of snap connection or bonding, etc. In the present application, it is preferred that the elastic plate is fixed in the groove 112 by means of plugging.

[0048] Specifically, the groove 112 is provided with a plug-in slot 113 on both side walls along the first direction. Figure 4 The two ends of the elastic plate are respectively inserted into the two insertion grooves 113 to fix the elastic plate.

[0049] Furthermore, the elastic plate has a first surface 121 and a second surface 122 opposite to each other. The first surface 121 abuts against the supporting member 13 , and a buffer space is formed between the second surface 122 and the bottom surface of the groove 112 .

[0050] Specifically, the distance between the two insertion slots 113 is smaller than the distance between the two ends of the elastic plate along the first direction. Thus, when the two ends of the elastic plate are inserted into the two insertion slots 113, the smaller spacing between the insertion slots 113 causes the elastic plate to bend, forming a bow shape. This creates a buffer space between the elastic plate and the groove 112. This buffer space facilitates elastic deformation of the elastic plate, thereby further stabilizing the connection between the carrier 13 and the support frame 11.

[0051] In one achievable manner, reference Figure 1The elastic plate is composed of multiple arcuate segments, wherein the convex area of each arcuate segment abuts against the support member 13, while the concave area of the arcuate segment abuts against the bottom wall of the groove 112. This structure can increase the contact points between the elastic plate and the support member 13, and between the elastic plate and the support frame 11, thereby improving the stability of the connection.

[0052] In another embodiment, Figure 5 As shown, the elastic plate has a certain curvature. One end of the elastic plate is inserted into the insertion groove 113 near the first side 115, while the other end remains free. In this embodiment, the distance between the two insertion grooves 113 is greater than the distance between the two ends of the elastic plate along the first direction.

[0053] This design allows the elastic plate to be fixed at one end while the free end at the other end can naturally bend and sag due to the curvature of the elastic plate, thereby forming a buffer space between the elastic plate and the groove 112. This buffer space not only accommodates the elastic deformation of the elastic plate, but also effectively supports the changes of the elastic plate during use, thereby stabilizing the connection between the bearing member 13 and the support frame 11 and enhancing the stability of the overall structure.

[0054] Furthermore, when the supporting member 13 slides into the support, the elastic plate of the bow structure can adapt to the movement of the supporting member 13, and after the supporting member 13 completely enters the limiting groove 111, it continues to stably support and contact the supporting member 13 to ensure the stability of the connection.

[0055] Specifically, when the carrier 13 slides from the first side surface 115 of the support frame 11 into the limiting groove 111, it slides along the slideway formed in the limiting groove 111 and gradually contacts the first surface 121 of the elastic plate. Due to the arched structure of the elastic plate, a large space is left between the end of the elastic plate closest to the first side surface 115 and the limiting groove 111. This design ensures that the carrier 13 will not be hindered by the elastic plate during the sliding process, thereby smoothly entering the limiting groove 111.

[0056] When the support member 13 contacts the elastic plate during its sliding process, it exerts a certain compressive force on the plate. This compressive force causes the plate to further bend or deform in the contact area. As the support member 13 continues to slide, the bending of the plate gradually deepens until the support member 13 reaches its predetermined position. During this process, the bending and deformation of the plate helps to accommodate the movement of the support member 13, providing the necessary cushioning and stabilizing support.

[0057] After the supporting member 13 slides into the predetermined position, the elastic deformation of the elastic plate generates a reverse elastic force, which presses the supporting member 13 tightly against the limiting surface 1110, thereby improving the stability of the connection between the supporting member 13 and the support frame 11.

[0058] As can be seen, the arched structure of the elastic plate enhances adaptability and dynamic compensation capabilities when the carrier 13 slides into the retaining groove 111. As described above, when the carrier 13 contacts the elastic plate, the elastic plate deforms according to the specific shape and sliding speed of the carrier 13, thereby dynamically adjusting. This dynamic adjustment ensures smooth and accurate sliding of the carrier 13.

[0059] In one embodiment, reference Figure 6 The elastic plate is provided with a through hole 120, which will change the original stress distribution on the elastic plate.

[0060] Specifically, when external force acts on the elastic plate, stress concentration may occur in the area around the through hole 120 , which may cause local plastic deformation. Therefore, the area around the through hole 120 may be more easily deformed than other areas.

[0061] This design can control the deformation of the elastic plate within a predetermined area by precisely designing the position and shape of the through hole 120, and keep the deformation of other areas (such as the area in contact with the carrier 13) relatively stable, thereby avoiding affecting the connection between the carrier 13 and the support frame 11.

[0062] Furthermore, the through hole 120 can not only reduce the weight of the elastic plate, but also reduce the cross-sectional area of the elastic plate, thereby reducing the stiffness of the elastic plate, so that the elastic plate is more likely to bend or deform when squeezed. Such bending and deformation help to provide elastic force between the carrier 13 and the support frame 11, making the connection between the two more stable.

[0063] In one embodiment, reference Figure 6 There are two through holes 120, and the two through holes 120 are symmetrically arranged on the central axis of the elastic plate.

[0064] In one embodiment, a plurality of through holes 120 are provided (not shown in the figure), and the plurality of through holes 120 are evenly distributed in the middle area of the elastic plate body.

[0065] Whether the through holes 120 are symmetrically arranged or evenly distributed, they are conducive to the uniform deformation of the elastic plate when subjected to extrusion force, so that the bearing member 13 can slide smoothly into the limiting groove 111, ensuring the stability of the connection between the bearing member 13 and the support frame 11.

[0066] In one embodiment, reference Figure 7 and 8A guide groove 114 is provided on the side of the support frame 11 facing away from the receiving groove 110. The guide groove 114 is connected to the second side surface 116 of the support frame 11. The guide groove 114 is mainly used to guide the sliding of the sample supporting assembly 1 on the loading platform 21 of the sample processing device 2 so that it can enter the loading platform 21 smoothly.

[0067] Specifically, the magnetic post 22 mounted on the stage 21 protrudes from the surface, and the width of the guide slot 114 precisely matches its outer diameter. This allows the sample carrier assembly 1, guided by the guide slot 114, to precisely align with the magnetic post 22 and smoothly slide along the outer side of the magnetic post 22 into the predetermined position on the stage 21, thereby reducing potential deviations or errors during installation.

[0068] In one embodiment, a stop portion 1140 is formed at one end of the guide groove 114 away from the second side surface 116. The main function of the stop portion 1140 is to limit the sliding range of the sample carrying component 1 to prevent the sample carrying component 1 from sliding too deep or beyond a predetermined range.

[0069] Specifically, when the component slides to the predetermined position, the stop surface contacts the magnetic column 22, thereby accurately stopping the sample carrier component 1 in the predetermined position. This design not only makes the positioning of the component more precise, but also helps prevent the component from sliding too deep or deviating from the target position, reducing the difficulty of adjustment.

[0070] Furthermore, the stopper can also serve as a physical marker to clearly indicate the correct sliding direction of the sample carrier assembly 1. This design effectively prevents the risk of the assembly malfunctioning or even causing potential damage to the device due to user misjudgment of direction.

[0071] This application also provides a sample processing device 2, referring to Figure 8 The sample processing device 2 includes a stage 21, on which the sample carrier assembly 1 is disposed. A magnetic column 22 is disposed on the stage 21, which provides a magnetic force to fix the sample carrier assembly 1 on the stage 21 by magnetic adsorption.

[0072] Compared to mechanical clamps, magnetic adsorption can quickly and accurately secure components in place, reducing the time required for adjustment and repositioning. In addition, this fixing method optimizes the operating process, improves the efficiency and reliability of the sample processing device 2, and makes the installation and positioning of the sample carrier component 1 more stable and accurate.

However, it is readily understood by those skilled in the art that the scope of protection of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present application.
