Detailed Implementation

[0065] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0066] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or it can be in a middle component. When a component is said to be "connected" to another component, it can be directly connected to the other component or it may be in a middle component.

[0067] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0068] Existing micro-powder scoops are mostly symmetrically designed, while the containers holding the powder are often narrow-mouthed and wide-bodied. When the amount of powder in the container is small, symmetrical scoops often struggle to scoop powder from the bottom and sides of the container. Furthermore, the handles of the scoops are generally flat or cylindrical, and during scooping, some powder often remains on the handle, affecting the amount of powder scooped and reducing the accuracy of powder transfer.

[0069] The micro-powder scoop provided by this utility model has its scoop body eccentrically positioned relative to a first axis serving as the working axis. This allows the scoop handle to rotate, causing the scoop body to rotate eccentrically, facilitating the scooping of powder from the bottom and side walls of the container and preventing powder residue and waste. Furthermore, a discharge surface is provided on the outer periphery of the scoop handle to reduce powder accumulation on the outer surface of the handle, thereby improving the accuracy of powder transfer.

[0070] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0071] For reference Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 This utility model provides a micro-powder scoop 10, including a handle 11 and a body 12. The handle 11 is used to rotate about a first axis X. The body 12 is connected to one end of the handle 11, and the body 12 has a first surface 121, and a powder scooping groove 122 is provided from the first surface 121 for holding powder. The geometric center of the first surface 121 is spaced from the first axis X.

[0072] The outer peripheral surface of the spoon handle 11 includes a discharge surface 111, which is connected to the spoon body 12. The positive normal Y of the first surface 121 and the positive normal Z of the discharge surface 111 have a first included angle A, satisfying: 0 < A ≤ 90°.

[0073] Specifically, the positive normal Y of the first surface 121 is the direction of the normal extending outward from the first surface 121, and the positive normal Z of the unloading surface 111 is the direction of the normal extending outward from the unloading surface 111.

[0074] Optionally, the inner wall of the powder scooping trough 122 is a smooth curved surface; specifically, the scoop body 12 is hemispherical or bowl-shaped. Correspondingly, the first surface 121 is annular.

[0075] Optionally, the micro-powder scoop 10 can be made of a material with high structural strength, such as metal, high-strength plastic, or ceramic. Metal materials include aluminum, aluminum alloys, magnesium alloys, iron, and iron alloys. The micro-powder scoop 10 can be a one-piece structure, meaning the handle 11 and the body 12 are manufactured using a single molding process, such as stamping or casting, without limitation. Alternatively, the handle 11 and body 12 can be separate structures, connected and fixed by welding, bonding, snap-fitting, or screwing.

[0076] Optionally, the discharge surface 111 is smoothly connected to the outer peripheral surface of the spoon body 12. There can be one or more discharge surfaces 111, without limitation. Multiple discharge surfaces 111 can be spaced apart, or they can be connected sequentially to form the outer peripheral surface of the spoon handle 11. The discharge surface 111 can be a plane, a curved surface, or a combination of both, without limitation.

[0077] Specifically, the first included angle A can be 10°, 20°, 30°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, etc., without restriction.

[0078] When A = 0°, the discharge surface 111 is flush with the first surface 121, forming a space on the discharge surface 111 that can accommodate powder, which is not conducive to powder flow. When A > 90°, the angle between the discharge surface 111 and the first surface 121 is too large (obtuse angle), resulting in low connection strength at the connection between the second rod 1132 of the micro-powder scoop 10 and the scoop body 12; and the orientation of the discharge surface 111 is opposite to the orientation of the first surface 121, which is not conducive to powder flow on the scoop handle 11. When 0 < A ≤ 90°, the discharge surface 111 and the first surface 121 have an angle (acute or right angle), and the powder can slide off the discharge surface 111, thereby reducing the accumulation of powder on the scoop handle 11 and satisfying the connection strength at the connection between the scoop handle 11 and the scoop body 12.

[0079] The micro-powder scoop 10 of this invention has a scoop body 12 that is eccentrically positioned with respect to the first axis X, which serves as the working axis. This causes the scoop handle 11 to rotate, thereby driving the scoop body 12 to rotate eccentrically. This achieves the scraping of residual powder from the bottom and side walls of the container holding the powder. Furthermore, the scoop handle 11 of this invention also has a discharge surface 111 on its outer periphery. By limiting the angle between the discharge surface 111 and the first surface 121 of the scoop body 12, the accumulation of powder on the outer periphery of the scoop handle 11 is reduced. This allows the micro-powder scoop 10 of this invention to effectively solve the problem of powder residue in automated powder scooping operations.

[0080] For reference Figure 1 , Figure 2 and Figure 6 In one embodiment, the unloading surface 111 includes a first unloading surface 1111 and a second unloading surface 1112. Both the first unloading surface 1111 and the second unloading surface 1112 are planes. The first unloading surface 1111 and the second unloading surface 1112 have a second included angle B, which satisfies: 0 < B < 90°.

[0081] Specifically, the second included angle B can be 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 80°, etc., without any restrictions.

[0082] When B = 0°, the first discharge surface 1111 and the second discharge surface 1112 overlap or face away from each other. At this time, the spoon handle 11 is thin and plate-like, resulting in poor rigidity and easy damage. When B ≥ 90°, the angle between the first discharge surface 1111 and the second discharge surface 1112 on the side facing the bottom wall of the spoon body 12 is obtuse or right angle, making the slope formed by the first discharge surface 1111 and the second discharge surface 1112 gentler, which is not conducive to powder flow and results in powder residue on the spoon handle 11 during the powder scooping operation. When 0 < B < 90°, the angle between the first discharge surface 1111 and the second discharge surface 1112 on the side facing the bottom wall of the spoon body 12 is acute angle, making the slope formed by the first discharge surface 1111 and the second discharge surface 1112 larger, which is conducive to powder flow and prevents powder from accumulating on the side of the discharge surface 111 facing the first surface 121, effectively reducing powder residue during the powder scooping operation.

[0083] Preferably, 30°≤B≤65°. This setting ensures that the included angle between the first discharge surface 1111 and the second discharge surface 1112 is not too small and thus affects the rigidity of the spoon handle 11, and also ensures that the included angle between the first discharge surface 1111 and the second discharge surface 1112 is not too large and thus affects the powder flow.

[0084] In one embodiment, the unloading surface 111 includes a first unloading surface 1111 and a second unloading surface 1112, wherein one of the first unloading surface 1111 and the second unloading surface 1112 is a plane and the other is a curved surface.

[0085] Optionally, when one of the first unloading surface 1111 and the second unloading surface 1112 is a curved surface, the curved surface can be any of the following: convex, concave, or a combination of convex and concave surfaces, without limitation. Furthermore, when one of them is a curved surface, the corresponding included angle can be the included angle between the positive normal of the first unloading surface 1111 and the positive normal of the second unloading surface 1112.

[0086] The included angle and shape between the first discharge surface 1111 and the second discharge surface 1112 are defined so that no space for containing powder is formed between the first discharge surface 1111 and the second discharge surface 1112, thereby reducing powder residue during the powder scooping operation.

[0087] Optionally, the first discharge surface 1111 and the second discharge surface 1112 can be directly connected, and at least one of them can be connected to the spoon body 12; or, the first discharge surface 1111 and the second discharge surface 1112 can be indirectly connected, and both can be connected to the spoon body 12, without limitation.

[0088] For reference Figure 6 In one embodiment, the outer peripheral surface of the spoon handle 11 further includes a connecting portion 112, and the first unloading surface 1111 and the second unloading surface 1112 are both connected to the connecting portion 112, and the connecting portion 112 is connected to the first surface 121.

[0089] Optionally, the connecting part 112 can be either planar or linear, without limitation. The connecting part 112 can be smoothly connected to the first unloading surface 1111 and the second unloading surface 1112, or it can be directly connected, without limitation.

[0090] The connecting part 112 allows for a smoother angle change between the first unloading surface 1111 and the second unloading surface 1112. The connecting part 112 also provides positioning and support during manufacturing, helping to ensure the dimensional and shape accuracy of each part of the spoon handle 11. During processing, the connecting part 112 serves as a reference, ensuring the accurate relative positions of the first unloading surface 1111, the second unloading surface 1112, and the first surface 121, thereby improving the overall quality of the product.

[0091] For reference Figure 2 and Figure 6 In one embodiment, the connecting part 112 is a connecting edge where the first unloading surface 1111 and the second unloading surface 1112 intersect, and the connecting edge is coplanar with or intersects with the first surface 121.

[0092] Alternatively, the connecting part 112 is a connecting plane, with the first unloading surface 1111 and the second unloading surface 1112 respectively connected to the opposite two sides of the connecting plane. The width of the connecting plane is less than the width of the first unloading surface 1111 and the width of the second unloading surface 1112. The connecting plane is coplanar with or intersects with the first surface 121.

[0093] Alternatively, the connecting part 112 is a connecting curved surface, with the first unloading surface 1111 and the second unloading surface 1112 respectively connected to the opposite two sides of the connecting curved surface, and the connecting curved surface protruding towards the side away from the unloading surface 111.

[0094] Optionally, the connecting part 112 can be planar or linear, without limitation. When the connecting part 112 is planar, its shape can be rectangular or arc-shaped. When the connecting part 112 is a connecting edge, it can minimize powder adhesion. When the connecting part 112 is a connecting curved surface, it serves to connect the two discharge surfaces and guide the powder flow.

[0095] Optionally, the width of the connecting plane is much smaller than the width of the first discharge surface 1111 and the second discharge surface 1112, in order to minimize the area of ​​powder adhesion. The planar shape of the connecting part 112 facilitates product processing.

[0096] The connection part 112 is provided so that the first discharge surface 1111 and the second discharge surface 1112 can be located on both sides of the first surface 121, which is conducive to the powder being guided from both sides and improving the flexibility of the product.

[0097] In the manufacturing process of the micro-powder scoop 10, the setting of the connecting edge can simplify the design and manufacturing of the mold and facilitate product molding. The setting of the connecting plane or connecting curved surface can provide more flexibility in the manufacturing of the scoop handle 11, and can adapt to different design requirements or manufacturing processes by adjusting the shape and size of the connecting plane or connecting curved surface.

[0098] For reference Figure 1 and Figure 7 In one embodiment, the spoon handle 11 includes a transition rod 113 connected to the spoon body 12, and a discharge surface 111 is disposed on the transition rod 113. The cross-sectional area of ​​the end of the transition rod 113 away from the spoon body 12 is greater than or equal to the cross-sectional area of ​​the end of the transition rod 113 connected to the spoon body 12.

[0099] Optionally, the spoon handle 11 also includes a transition block. One end of the transition block is connected to the transition rod 113, and the other end of the transition block is connected to the outer wall surface of the spoon body 12. The outer wall surface of the spoon body 12 is a smooth curved surface that is connected to the first surface 121 and protrudes away from the first surface 121. The transition block, the transition rod 113, and the spoon body 12 are all smoothly connected.

[0100] The cross-sectional shape of the transition rod 113 can be triangular, sector-shaped, semi-circular, rhomboid, circular, elliptical, rectangular, etc., without restriction. The transition rod 113 can be an integral structure with a consistent cross-sectional shape, or a segmented structure with different cross-sectional shapes, without restriction.

[0101] When the spoon handle 11 is under stress, the transition rod 113, as a structure connecting the spoon body 12 and the gripping part, needs to withstand certain tensile, compressive, and torsional forces. When the cross-sectional area of ​​the end of the transition rod 113 furthest from the spoon body 12 is greater than or equal to the cross-sectional area of ​​the end connected to the spoon body 12, the "wider at the top and narrower at the bottom" design allows the transition rod 113 to better distribute stress. The closer to the spoon body 12, the smaller the cross-sectional area of ​​the transition rod 113, which minimizes powder adhesion to the spoon handle 11; the farther away from the spoon body 12, the larger the cross-sectional area of ​​the transition rod 113, which allows for better gripping and operation.

[0102] For reference Figure 1 In one embodiment, the transition rod 113 includes a first rod 1131 and a second rod 1132 connected to each other. The end of the second rod 1132 away from the first rod 1131 is connected to the spoon body 12. The second rod 1132 has a discharge surface 111. The cross-sectional shapes of the first rod 1131 and the second rod 1132 are different.

[0103] Optionally, the outer surfaces of both the first rod 1131 and the second rod 1132 are polished. The first rod 1131 and the second rod 1132 are smoothly connected.

[0104] The combination of different cross-sectional shapes of the first rod 1131 and the second rod 1132 can give the spoon handle 11 more functions. The first rod 1131 is used for manual holding or connecting other components (such as the drive mechanism), which helps to improve the flexibility of the spoon handle 11. The second rod 1132 has a discharge surface 111 to avoid powder residue during the scooping operation.

[0105] For reference Figure 1 and Figure 6 In one embodiment, the first rod 1131 and the second rod 1132 are smoothly connected; the cross-sectional area of ​​the first rod 1131 gradually decreases from the end away from the second rod 1132 toward the end connected to the second rod 1132; the cross-sectional area of ​​the second rod 1132 gradually decreases from the end connected to the first rod 1131 toward the end connected to the spoon body 12.

[0106] Optionally, the cross-sectional shape of the first rod 1131 is circular or elliptical, and the first rod 1131 as a whole is truncated cone. Alternatively, the cross-sectional shape of the first rod 1131 is polygonal (such as regular pentagon, regular hexagon, regular octagon, etc.).

[0107] The cross-sectional shape of the second rod 1132 can be polygonal (such as triangle, quadrilateral, etc.), and the polygon can be a straight polygon or a curved polygon, without restriction. When the connecting part 112 is a connecting edge and both the first unloading surface 1111 and the second unloading surface 1112 are planar, the second rod 1132 as a whole can be pyramidal or frustum-shaped.

[0108] The end of the first rod 1131 with a larger cross-sectional area can serve as a force application point, allowing the drive mechanism or operator to better apply power to the micro-powder scoop 10. The gradually decreasing cross-sectional area enables the power to be transmitted more effectively to the second rod 1132 and the scoop body 12, improving operational efficiency. Furthermore, the gradually decreasing cross-sectional area of ​​the first rod 1131 also allows for a better transition connection with the second rod 1132. The gradually decreasing cross-sectional area of ​​the second rod 1132 is more flexible, facilitating the control of the direction and angle of movement of the micro-powder scoop 10 by the drive mechanism or operator. In addition, the gradually decreasing cross-sectional area of ​​the second rod 1132 also helps to reduce powder adhesion.

[0109] For reference Figure 1 and Figure 7 In one embodiment, the centerline of the spoon handle 11 is a first axis X, or at least a portion of the first axis X is located on the outside of the spoon handle 11.

[0110] Optionally, at least a portion of the spoon handle 11 can be an axisymmetric structure, with the first axis X being the axis of the spoon handle 11 itself. For example, when the first rod 1131 of the spoon handle 11 is a frustum as a whole, the first axis X is the axis of symmetry of the first rod 1131, and the first axis X is located within the first rod 1131.

[0111] Optionally, at least part of the first axis X is located outside the spoon handle 11, and the spoon handle 11 rotates around the first axis X to scoop and pour powder. The first axis X is the working axis of the micro-powder scooping spoon 10. In this case, the spoon handle 11 can be a non-axisymmetric structure.

[0112] The position of the first axis X is set to correspond to the structure of the spoon handle 11, making the overall movement of the spoon handle 11 more flexible and accurate.

[0113] For reference Figures 1 to 4 In one embodiment, the micro-powder scoop 10 further includes a powder scraper 13, which is connected to the scoop body 12. The powder scraper 13 has a second surface 131, which is connected to the first surface 121.

[0114] Optionally, the powder scraper 13 and the spoon body 12 are an integral structure. The first surface 121 of the powder scraper 13 and the outer peripheral surface of the spoon body 12 can be smoothly connected or directly connected, without restriction.

[0115] The powder scraper 13 can further scrape off the powder on the inner wall of the container. The presence of the powder scraper 13 allows the operator to scrape up and scoop out the powder remaining on the inner wall of the container with only one or a few operations, which greatly improves the powder removal efficiency and avoids powder residue in the container.

[0116] For reference Figures 1 to 3 In one embodiment, the second surface 131 includes a first edge 1311 and a second edge 1312. The first edge 1311 is located on the side of the first surface 121 away from the first axis X, and the second edge 1312 is located on the side of the first surface 121 away from the spoon handle 11. The first edge 1311 and the second edge 1312 have an included angle. The first edge 1311 is used to scrape powder off the side wall of the container, and the second edge 1312 is used to scrape powder off the bottom wall of the container.

[0117] Since the geometric center of the first surface 121 is spaced from the first axis X, the first surface 121 has a side away from the first axis X and a side close to the first axis X.

[0118] Optionally, both the first edge 1311 and the second edge 1312 are straight lines. The first edge 1311 is smoothly connected to the side of the first surface 121 away from the first axis X, such as the first edge 1311 being tangent to the side of the first surface 121 away from the first axis X; the second edge 1312 is smoothly connected to the side of the first surface 121 away from the handle 11, such as the second edge 1312 being tangent to the side of the first surface 121 away from the handle 11.

[0119] Optionally, the angle between the first edge 1311 and the second edge 1312 is less than 180°, specifically it can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, etc., without limitation. When the angle between the first edge 1311 and the second edge 1312 is greater than or equal to 180°, the contact area between the second surface 131 and the bottom wall of the container is small, which is not conducive to scraping off the powder on the bottom wall of the container. Preferably, the angle between the first edge 1311 and the second edge 1312 is 90°, which allows both the first edge 1311 and the second edge 1312 to maximize contact with the inner wall of the container.

[0120] If residual powder inside the container is not cleaned in time, it may deteriorate due to moisture, oxidation, or other reasons, resulting in waste. The first edge 1311 and the second edge 1312 of the powder scraper 13 can effectively scrape off residual powder on the side and bottom walls of the container, reducing powder waste and improving powder utilization.

[0121] For reference Figure 3In one embodiment, the second surface 131 further includes a third edge 1313, one end of which is connected to the first edge 1311, and the other end of which is connected to the second edge 1312. The third edge 1313 is used to smoothly connect the first edge 1311 and the second edge 1312. Specifically, the third edge 1313 is a smooth curve.

[0122] The third edge 1313 is provided to make the first edge 1311 and the second edge 1312 smoothly connected, thereby avoiding damage to the inner wall of the container by the tip of the powder scraper 13 and improving the service life of the container.

[0123] For reference Figure 1 , Figure 3 and Figure 6 In one embodiment, the first surface 121 and the second surface 131 have a third included angle C, satisfying: 90°≤C≤240°.

[0124] Specifically, the included angle C can be 90°, 110°, 120°, 140°, 150°, 160°, 180°, 200°, 220°, 240°, etc., without any restrictions.

[0125] When C < 90°, the angle between the first surface 121 and the second surface 131 is acute, which is not conducive to the second surface 131 scraping the powder off the inner wall of the container. Furthermore, this creates a space between the first surface 121 and the second surface 131 to accommodate the powder, resulting in powder accumulation when the scraper 13 contacts and scrapes the powder off the inner wall of the container. When C > 240°, the angle between the first surface 121 and the second surface 131 is too large, and the second surface 131 extends towards the bottom wall of the spoon body 12, which is not conducive to the scraper 13 scraping the powder off the inner wall of the container. When 90°≤C≤240, the included angle between the first surface 121 and the second surface 131 is moderate. Taking the orientation of the first surface 121 after scooping powder (the first surface 121 is parallel to the horizontal plane) as a reference, when the angle between the first surface 121 and the second surface 131 is limited to 90°-180°, the second surface 131 faces upward, which makes it easier to scrape the powder off the container wall when scooping powder, and the scraped powder can easily transition from the second surface 131 to the powder scooping trough 122, avoiding the accumulation of powder on the second surface 131. When the angle between the first surface 121 and the second surface 131 is limited to 180°-240°, the second surface 131 faces downward, which makes it easier to guide the flow after scooping powder and reduce powder residue on the second surface 131.

[0126] Preferably, the third included angle C is 180°, meaning the first surface 121 is flush with the second surface 131, and the second surface 131 is located at the outer edge of the first surface 121. This arrangement allows for simultaneous scraping of powder by the second surface 131 and scooping of powder by the powder scooping trough 122, improving scooping efficiency. Furthermore, the size of the second surface 131 is as small as possible to reduce powder accumulation on it.

[0127] Optionally, the spoon handle 11, the discharge surface 111, the connecting part 112, the spoon body 12, and the powder scraper 13 can all be coated with polytetrafluoroethylene (PTFE) or diamond-like carbon (DLC) film to further reduce powder adhesion.

[0128] For reference Figure 1 and Figure 4 In one embodiment, the spoon handle 11 further includes a connecting rod 114, which is connected to the end of the transition rod 113 away from the spoon body 12, and the end of the connecting rod 114 away from the transition rod 113 is used to connect to the drive mechanism.

[0129] Optionally, the connecting rod 114 can be an axisymmetric structure, with its axis of symmetry coinciding with the first axis X. The connecting rod 114 extends along the first axis X, and its cross-sectional shape can be circular, regular polygonal, elliptical, petal-shaped, semi-circular, arc-shaped, etc., without limitation. For example, when the cross-sectional shape of the connecting rod 114 is arc-shaped, the center of the circle corresponding to the arc falls on the first axis X.

[0130] The radial dimension of the end of the transition rod 113 connected to the connecting rod 114 is greater than the radial dimension of the end connected to the spoon body 12. Specifically, the radial dimension of the transition rod 113 gradually decreases along the direction closer to the spoon body 12.

[0131] The connecting rod 114 extends along the first axis X, allowing the micro-powder scoop 10 to rotate around its own axis. Meanwhile, the radial dimension of the transition rod 113 gradually decreases, which helps to reduce the accumulation of powder on the surface of the transition rod 113 and facilitates the power transmission of the drive mechanism to the scoop body 12.

[0132] The connecting rod 114 is used to connect and fix with the docking structure 20 of the micro powder scoop assembly 100. The shape of the cross-section of the connecting rod 114 is defined so that the connection between the connecting rod 114 and the docking structure 20 is tighter after assembly, and the connecting rod 114 and the docking structure 20 are prevented from rotating relative to each other.

[0133] For reference Figure 1 and Figure 7 In one embodiment, the connecting rod 114 has a first axis X; the outer peripheral surface of the end of the connecting rod 114 that is connected to the transition rod 113 is provided with a limiting portion 115; and / or, the outer peripheral surface of the connecting rod 114 has a positioning portion 116 that cooperates with the driving mechanism.

[0134] Optionally, the limiting part 115, the connecting rod 114, and the transition rod 113 can be an integral structure or a separate structure, without limitation.

[0135] The limiting part 115 may be annular, and is sleeved on the end where the connecting rod 114 and the transition rod 113 are connected. The limiting part 115 protrudes from the connecting rod 114 in the circumferential direction. When the connecting rod 114 is mounted on the drive mechanism, the limiting part 115 can restrict the drive mechanism from moving relative to the connecting rod 114 in the axial direction, thus ensuring the stability of the structure.

[0136] The positioning part 116 can be disposed on the limiting part 115 or directly disposed on the outer peripheral surface of the connecting rod 114. For example, the positioning part 116 can be a flat structure disposed on the outer peripheral surface of the connecting rod 114. The connecting rod 114 can be cylindrical, and cut along its axial direction; the resulting plane can serve as the positioning part 116. The cross-sectional shape of the cut connecting rod 114 is arc-shaped. The positioning part 116 allows the connecting rod 114 and the drive mechanism to be aligned during installation, improving assembly accuracy; simultaneously, the positioning part 116 also serves as a foolproof mechanism. Correspondingly, the drive mechanism or the second connector 22 described below, which abuts the connecting rod 114, has a structure that mates with the positioning part 116, such as a boss whose shape and size match the positioning part 116, to prevent relative rotation between the two and improve assembly accuracy.

[0137] Specifically, the connecting rod 114 includes a third surface 1141 and a fourth surface 1142. The third surface 1141 is a plane, and the fourth surface 1142 is a smooth curved surface. Both sides of the third surface 1141 are connected to the fourth surface 1142, and the cross-sectional shape of the connecting rod 114 is correspondingly arc-shaped. The limiting part 115 protrudes from the fourth surface 1142, and the positioning part 116 is flush with the third surface 1141, or the third surface 1141 forms the positioning part 116.

[0138] The end face of the limiting part 115 away from the spoon body 12 is used to abut against the drive mechanism or docking structure 20. The positioning part 116 cooperates with the drive mechanism to facilitate the insertion of the micro powder scoop 10, and avoids relative rotation between the connecting rod 114, the docking structure 20 and the drive structure, thus playing a foolproof role. This simplifies the assembly process of the connecting rod 114 and the drive mechanism or docking structure 20, and improves product quality and production efficiency.

[0139] In one embodiment, the micro-powder scoop 10 further includes a connector, which is connected to the scoop handle 11 and is used to connect to a drive mechanism.

[0140] Optionally, the connector can be a threaded connector, a snap-fit ​​connector, a magnetic connector, a plug-in connector, etc., without restriction.

[0141] Optionally, the connection between the connector and the spoon handle 11 can be welding, bonding, screwing, etc.; or, the connector and the spoon handle 11 can be integrally formed, without limitation.

[0142] The connector allows the micro-powder scoop 10 to be directly connected to the drive mechanism, enabling quick replacement of the micro-powder scoop 10.

[0143] In laboratory settings, powder dispensing traditionally involves manual scooping, weighing, and dispensing of powder using spoons. Different types of powder require the spoons to be changed or cleaned to avoid cross-contamination. In automated scenarios, traditional manual spoon-using methods cannot meet the demands of automated equipment, hindering automatic equipment docking and rapid replacement.

[0144] For reference Figure 1 and Figure 4 The present invention provides a micro powder scoop assembly 100, including a docking structure 20 and a micro powder scoop 10 as described in any of the aforementioned embodiments. One end of the docking structure 20 is connected to the handle 11 of the micro powder scoop 10, and the other end of the docking structure 20 is used to connect to a driving mechanism. The driving mechanism is used to drive the handle 11 to rotate around the first axis X.

[0145] Optionally, the connection method between the docking structure 20 and the spoon handle 11 can be screw connection, magnetic connection, snap connection, etc., without limitation.

[0146] The micro-powder scoop assembly 100 of this utility model, using the micro-powder scoop 10 in any of the aforementioned embodiments, can scrape off residual powder from the bottom and side walls of the container holding the powder, and can effectively solve the problem of powder residue in automated powder scooping action, improving the accuracy of powder transfer; on this basis, a docking structure 20 is set to automatically load and replace the micro-powder scoop 10, meeting the needs of automated work, and helping to achieve high-throughput orderly storage of multiple micro-powder scoops 10, improving work efficiency.

[0147] For reference Figure 4 , Figure 5 and Figure 8 In one embodiment, the docking structure 20 includes a first connector 21 and a second connector 22. The spoon handle 11 is connected to the second connector 22. The first connector 21 is used to connect to the drive mechanism. The first connector 21 and the second connector 22 are detachably connected in the direction of the first axis X.

[0148] Optionally, the detachable connection method between the spoon handle 11 and the second connector 22, and between the first connector 21 and the second connector 22, can be magnetic connection, threaded connection, snap-fit, etc., without limitation. Specifically, the first connector 21 and the second connector 22 are respectively provided with snap-fit ​​structures. For example, the first connector 21 is provided with a snap-fit ​​protrusion, and the second connector 22 is provided with a corresponding snap-fit ​​groove or bayonet. When the first connector 21 and the second connector 22 approach each other in the first axis X direction, the snap-fit ​​protrusion enters the snap-fit ​​groove or bayonet to achieve snap-fit ​​fixation. Alternatively, the first connector 21 and the second connector 22 are respectively provided with external threads and internal threads. By rotating the first connector 21 or the second connector 22, the threads are made to mesh with each other, thereby achieving connection.

[0149] Optionally, the connection method between the first connector 21 and the drive mechanism can be flange connection, pin connection, key connection, etc., without restriction.

[0150] The first connector 21 and the second connector 22, which are detachably connected in the direction of the first axis X, automatically load and unload the micro powder scoop 10, and drive the micro powder scoop 10 to scoop and pour powder through the drive mechanism, which helps to automate the micro powder scoop assembly 100 and improve work efficiency.

[0151] For reference Figure 5 and Figure 8 In one embodiment, the first connector 21 includes a first fixing part 211 and a plurality of first insertion parts 212 spaced apart in the circumferential direction of the first fixing part 211, and a first limiting groove 213 is formed between two adjacent first insertion parts 212.

[0152] The second connector 22 includes a second fixing part 221 and a plurality of second insertion parts 222 arranged circumferentially on the second fixing part 221, and two adjacent second insertion parts 222 surround to form a second limiting groove 223.

[0153] The first plug-in portion 212 is used to extend into the second limiting groove 223 in a corresponding manner, and the second plug-in portion 222 is used to extend into the first limiting groove 213 in a corresponding manner, with the plurality of first plug-in portions 212 and the plurality of second plug-in portions 222 in close contact.

[0154] Optionally, the first connector 21 and the second connector 22 are made of materials with high structural strength, such as aluminum alloy, magnesium alloy, iron, iron alloy, high-strength plastic, etc. The first insertion part 212 and the first fixing part 211, the second insertion part 222 and the second fixing part 221 can be an integral structure manufactured using a one-piece molding process, such as stamping or casting, without limitation. Alternatively, the first insertion part 212 and the first fixing part 211, the second insertion part 222 and the second fixing part 221 can also be separate structures, connected and fixed by welding, bonding, snap-fitting, screwing, etc.

[0155] Optionally, a plurality of first insertion portions 212 are equally spaced along the circumference of the first fixing portion 211; a plurality of second insertion portions 222 are equally spaced along the circumference of the second fixing portion 221. Correspondingly, the first limiting groove 213 is evenly distributed along the circumference of the first fixing portion 211, and the second limiting groove 223 is evenly distributed along the circumference of the second fixing portion 221, and the first limiting groove 213 and the second limiting groove 223 play a limiting role in the circumference of their respective fixing portions.

[0156] Optionally, at least a portion of the first insertion portion 212 is in close contact with the inner wall surface of the second limiting groove 223, and at least a portion of the second insertion portion 222 is in close contact with the inner wall surface of the first limiting groove 213.

[0157] Optionally, from the end near the first fixing part 211 to the end away from the first fixing part 211, the size of the first insertion part 212 in the circumferential direction of the first fixing part 211 remains unchanged or gradually decreases; correspondingly, from the end near the second fixing part 221 to the end away from the second fixing part 221, the size of the second insertion part 222 in the circumferential direction of the second fixing part 221 remains unchanged or gradually decreases.

[0158] By defining the structure of the first connector 21 and the second connector 22, the first connector 21 and the second connector 22 are fixed by corresponding insertion of the first insertion part 212 and the second insertion part 222, which can efficiently realize the replacement and docking of the micro powder scoop 10, and help improve the utilization efficiency of the micro powder scoop assembly 100. At the same time, the first connector 21 and the second connector 22 can be limited in the circumferential direction of the first fixing part 211 to prevent the two connectors from rotating relative to each other, thereby improving the stability and working accuracy of the micro powder scoop assembly 100.

[0159] For reference Figure 8In one embodiment, the first insertion portion 212 includes a first sub-portion 2121 and a second sub-portion 2122 connected together. The first sub-portion 2121 is connected to the first fixing portion 211. The two sides of the first sub-portion 2121 in the circumferential direction are parallel to each other in the first fixing portion 211. The dimension of the second sub-portion 2122 in the circumferential direction of the first fixing portion 211 gradually decreases in the direction away from the first sub-portion 2121.

[0160] The second insertion part 222 includes a third sub-part 2221 and a fourth sub-part 2222 connected together. The third sub-part 2221 is connected to the second fixing part 221. The two sides of the third sub-part 2221 in the circumferential direction are parallel to each other in the second fixing part 221. The dimension of the fourth sub-part 2222 in the circumferential direction of the second fixing part 221 gradually decreases in the direction away from the third sub-part 2221.

[0161] Optionally, the tops of the second sub-part 2122 and the fourth sub-part 2222 are pointed.

[0162] Optionally, the first sub-part 2121 extends parallel to the two circumferential sides of the first fixing part 211 and along the first axis X. Correspondingly, the two side walls of the first limiting groove 213 near the bottom wall are parallel. The third sub-part 2221 extends parallel to the two circumferential sides of the second fixing part 221 and along the first axis X. Correspondingly, the two side walls of the second limiting groove 223 near the bottom wall are parallel. This arrangement prevents the first connector 21 and the second connector 22 from separating during rotation.

[0163] The distance between the tops of two adjacent second sub-parts 2122 corresponds to the size of the opening of the first limiting groove 213, and the distance between the tops of two adjacent fourth sub-parts 2222 corresponds to the size of the opening of the second limiting groove 223. The opening of the first limiting groove 213 is larger in the circumferential direction of the first fixing part 211 than the bottom wall of the first limiting groove 213 is larger in the circumferential direction of the first fixing part 211; the opening of the second limiting groove 223 is larger in the circumferential direction of the second fixing part 221 than the bottom wall of the second limiting groove 223 is larger in the circumferential direction of the second fixing part 221.

[0164] The tops of the second sub-part 2122 and the fourth sub-part 2222 are pointed, which makes the multiple first insertion parts 212 and multiple second insertion parts 222 form a sawtooth shape, which plays a certain guiding role in the extension direction of the first axis X, facilitating the insertion of the first connector 21 and the second connector 22; the first limiting groove 213 and the second limiting groove 223 are set in the circumferential direction of the first fixing part 211 to limit the first connector 21 and the second connector 22. The two work together to improve the insertion efficiency of the first connector 21 and the second connector 22, and avoid relative sliding after the two are inserted.

[0165] For reference Figure 9 and Figure 10 In one embodiment, the first connector 21 further includes a mounting cylinder 23, which is connected to the first fixing part 211, and a plurality of first insertion parts 212 are disposed on the outer periphery of the mounting cylinder 23; when the first connector 21 is connected to the second connector 22, the plurality of second insertion parts 222 are in close contact with the outer peripheral surface of the mounting cylinder 23; or, the second connector 22 further includes a mounting cylinder 23, which is connected to the second fixing part 221, and a plurality of second insertion parts 222 are disposed on the outer periphery of the mounting cylinder 23; when the first connector 21 is connected to the second connector 22, the plurality of first insertion parts 212 are in close contact with the outer peripheral surface of the mounting cylinder 23.

[0166] Optionally, the connection method between the mounting sleeve 23 and the first fixing part 211 or the second fixing part 221 can be screwed, welded, glued, snap-fitted, etc., without restriction.

[0167] By providing a mounting sleeve 23, the first insertion part 212 and the second insertion part 222 are provided with certain support. The mounting sleeve 23 is in close contact with the first insertion part 212 and the second insertion part 222 to provide a certain frictional resistance, preventing the first connector 21 and the second connector 22 from moving relative to each other in the axial and / or radial direction in the first fixing part 211 after insertion, thereby helping to improve the connection strength of the docking structure 20. In addition, the mounting sleeve 23 can also reduce the machining accuracy and machining difficulty of the insertion part and the limiting groove of the two connectors, and can ensure the smooth docking of the two connectors under certain machining dimensional deviations without affecting the structural stability.

[0168] For reference Figure 5 , Figure 9 and Figure 10 In one embodiment, the docking structure 20 further includes at least one magnetic element 24, which is used to magnetically connect the first connector 21 and the second connector 22 in the direction of the first axis X; the magnetic element 24 is fixedly connected to the first connector 21, the second connector 22 has strong magnetism, and the magnetic element 24 is used to magnetically connect to the second connector 22, so that the first connector 21 and the second connector 22 are fixedly connected; or, the magnetic element 24 is fixedly connected to the second connector 22, the first connector 21 has strong magnetism, and the magnetic element 24 is used to magnetically connect to the first connector 21, so that the first connector 21 and the second connector 22 are fixedly connected; or, the first connector 21 and the second connector 22 are each connected to a magnetic element 24, and the two magnetic elements 24 attract each other to fix the first connector 21 and the second connector 22.

[0169] Optionally, the first connector 21 and the second connector 22 cannot both possess strong magnetism. The connectors connected to the magnetic component 24 are generally made of non-magnetic stainless steel or non-metallic materials. This prevents the magnetic connectors from continuously conducting magnetism to the magnetic component 24, thus affecting the performance of the magnetic component 24. If the first connector 21 or the second connector 22 possesses strong magnetism, it can be considered that the first connector 21 or the second connector 22 is made of a strong magnetic material and can be attracted by the magnetic component 24. The strong magnetic material can be a ferromagnetic material or a ferrimagnetic material, such as iron or stainless steel, specifically 17-4PH stainless steel or 440C stainless steel.

[0170] Optionally, the magnetic component 24 can be a magnet, specifically a neodymium iron boron magnet, a samarium cobalt magnet, an alnico magnet, a rubber magnet, etc., without limitation.

[0171] Optionally, the magnetic component 24 is a cylindrical permanent magnet, and the magnetic poles of the magnetic component 24 are distributed along its own radial direction.

[0172] The first connector 21, the second connector 22, and the magnetic component 24 generate an axial force along the extension direction of the first axis X through magnetic force, which simplifies the docking operation of the first connector 21 and the second connector 22, saves assembly time, and allows for quick switching between multiple micro-powder scoops 10. The magnetic component 24 can be set in at least one of the first connector 21 and the second connector 22, which facilitates adaptation to different installation positions and adjustment of the layout of the docking structure 20, thereby improving the installation flexibility of the docking structure 20.

[0173] For reference Figures 8 to 10 In one embodiment, the magnetic element 24 is only connected and fixed to the first connector 21, and at least a portion of the magnetic element 24 is located within the space enclosed by a plurality of first insertion portions 212. The second connector 22 has strong magnetism. The second connector 22 also includes a mounting cylinder 23, which is connected to the second fixing portion 221. A plurality of second insertion portions 222 are disposed on the outer periphery of the mounting cylinder 23. The mounting cylinder 23 has a receiving hole extending along the first axis X. When the first connector 21 and the second connector 22 are connected, the plurality of first insertion portions 212 are in close contact with the outer peripheral surface of the mounting cylinder 23, and the magnetic element 24 extends into the receiving hole and is magnetically connected to the mounting cylinder 23.

[0174] Optionally, the connection method between the magnetic component 24 and the first connector 21 can be bonding, welding, snap-fitting, screwing, etc., without limitation. Specifically, the outer peripheral surface of the first fixing part 211 of the first connector 21 has a mounting hole 2111, and the outer peripheral surface of the magnetic component 24 has a corresponding mounting groove 241. Threaded components and other mounting parts extend from the mounting hole 2111 into the mounting groove 241 to achieve the connection and fixation between the magnetic component 24 and the first connector 21.

[0175] Optionally, threaded holes are provided on the walls of both the mounting cylinder 23 and the second fixing part 221, and the second fixing part 221 and the mounting cylinder 23 are threaded together. Optionally, the mounting cylinder 23 and the second fixing part 221 can be an integrally formed structure.

[0176] Optionally, the receiving hole and the magnetic component 24 are provided correspondingly, and the cross-sectional shape of the receiving hole and the magnetic component 24 can be circular, elliptical, rectangular, etc., without limitation.

[0177] The first connector 21 is connected and fixed to the magnetic component 24. The second connector 22 has strong magnetism. The first connector 21 and the second connector 22 are connected by the principle of magnetic adsorption. This makes it easy to connect and disconnect the first connector 21 and the second connector 22 in the direction of the first axis X. The positioning accuracy is relatively high, and it can quickly and accurately connect the spoon handle 11 to the drive mechanism indirectly, which helps to improve the working efficiency of the experimental equipment.

[0178] In practical applications, the first connector 21 is fixedly connected to the drive mechanism, and the second connector 22 is fixedly connected to the handle 11 of the micro-powder scoop 10. The drive mechanism moves the first connector 21 to mate with the second connector 22. The micro-powder scoops 10 are generally arranged in an array on a storage rack. If the magnetic component 24 is placed on the second connector 22, adjacent micro-powder scoops 10 will attract each other and shift their positions, thus affecting the mate between the first connector 21 and the second connector 22, causing the micro-powder scoops 10 to fail to load.

[0179] For reference Figure 4 and Figure 7 In one embodiment, the outer peripheral surface of the end of the second fixing part 221 facing away from the second insertion part 222 is provided with a snap-fit ​​groove 2211. The snap-fit ​​groove 2211 extends along the circumferential direction of the second fixing part 221 and is used to cooperate with the clamping mechanism.

[0180] Optionally, the snap-fit ​​groove 2211 can be an annular groove with the ends connected. There can also be multiple snap-fit ​​grooves 2211, which are spaced apart in the circumferential direction of the second fixing part 221.

[0181] The snap-fit ​​groove 2211 is provided to facilitate snap-fit ​​with the clamping mechanism, so that the clamping mechanism can drive the micro powder scoop 10 to separate or connect the first connector 21 and the second connector 22 in the direction of the first axis X, thereby realizing the replacement of the micro powder scoop 10 and improving the working efficiency of the micro powder scoop assembly 100.

[0182] For reference Figure 4 and Figure 5In one embodiment, the second connector 22 further includes a guide portion 224, which is disposed at the end of the second fixing portion 221 facing away from the second insertion portion 222. The guide portion 224 has a receiving hole extending along the first axis X, into which a portion of the spoon handle 11 extends. The outer peripheral surface of the second fixing portion 221 protrudes from the outer peripheral surface of the guide portion 224. The guide portion 224 is used to guide and position the micro-powder scoop 10 when it is placed on the storage rack.

[0183] The guide portion 224 includes a first segment 2241 and a second segment 2242 connected together. The first segment 2241 is connected to the second fixing portion 221, and the second segment 2242 has a radial dimension that gradually decreases in the direction away from the second fixing portion 221.

[0184] Optionally, the second fixing part 221, the first section 2241 and the second section 2242 are formed into an integrated structure through stamping, casting and other integrated processes.

[0185] A guide portion 224 is provided at the end of the second connector 22 away from the first connector 21. The guide portion 224 is generally conical and serves to guide the micro-powder scoop 10 when it is placed on the storage rack, thereby improving the working efficiency of the micro-powder scoop assembly 100. Placing the micro-powder scoops 10 in an array on the storage rack enables high-throughput, orderly storage of the micro-powder scoops 10 during the powder dispensing process.

[0186] This utility model provides an experimental device, including a driving mechanism and a micro powder scoop 10 as described in any of the foregoing embodiments.

[0187] Alternatively, it may include a drive mechanism and a micro-powder scoop assembly 100 as described in any of the foregoing embodiments, wherein the drive mechanism is connected to the docking structure 20 of the micro-powder scoop assembly 100, and the drive mechanism is used to drive the micro-powder scoop assembly 100 to rotate.

[0188] Optionally, the drive mechanism can be a robotic arm, motor-driven, hydraulically driven, pneumatically driven, etc., without limitation. When the drive mechanism is motor-driven, it can specifically correspond to a DC motor, AC motor, servo motor, stepper motor, etc.; when the drive mechanism is hydraulically driven, it can specifically correspond to a hydraulic pump, hydraulic motor, hydraulic cylinder, etc.; when the drive mechanism is pneumatically driven, it can specifically correspond to a cylinder, pneumatic motor, solenoid valve, etc., without limitation.

[0189] Optionally, the connection method between the docking structure 20 and the spoon handle 11 can be screwed, snap-fitted, magnetically connected, etc., without limitation.

[0190] By setting up the docking structure 20 and the micro powder scoop 10, the micro powder scoop 10 can be quickly loaded and replaced during the powder dispensing process. At the same time, using the micro powder scoop 10 described in any of the aforementioned embodiments can reduce powder residue and waste when there is little powder in the container.

[0191] In one embodiment, the docking structure 20 includes a first connector 21 and a second connector 22. The first connector 21 is connected to the driving mechanism, and the second connector 22 is connected to the spoon handle 11.
