[0033] In order to make the purpose, advantages and features of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings. It should be noted that the drawings are all in a very simplified form and are not in precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model. The same or similar reference numerals in the drawings represent the same or similar components.

[0034] Figure 1 The schematic diagram of the structure of the loading device 10 provided by some embodiments of the utility model is shown. Figure 1 As shown, the loading device 10 includes a carrier 100 and a locking mechanism 200. The carrier 100 has a carrying surface 101, and the carrying surface 101 is used to carry a target object. The locking mechanism 200 is arranged on the carrier 100 and is located on one side of the carrying surface 101. The locking mechanism 200 is used to press against the target object carried on the carrying surface 101, so that the target object remains stationary relative to the carrier 100, thereby achieving the purpose of locking the target object and the carrier 100.

[0035] Please continue to refer to Figure 1 , and combined with Figures 2 to 4 , the locking mechanism 200 includes a base 210, a pressure block 220 and a positioning member 230. The base 210 is connected to the carrier 100 and is located on one side of the carrier surface 101. The pressure block 220 is rotatably connected to the base 210, and by controlling the rotation of the pressure block 220 relative to the base 210, the pressure block 220 can be switched between a first position and a second position. In an embodiment of the utility model, when the pressure block 220 is in the first position, the pressure block 220 is partially arranged opposite to the carrier surface 101, and there is also a gap between the pressure block 220 and the carrier surface 101, so that the area between the pressure block 220 and the carrier surface 101 forms a slot (not shown in the figure); when the pressure block 220 is in the second position, the pressure block 220 deviates from the carrier surface 101 (as shown in the figure); Figure 1 The positioning member 230 is used to keep the pressing block 220 at the first position or the second position.

[0036] More specifically, at least two positioning holes 231 are provided on one of the surface of the pressing block 220 facing the base 210 and the surface of the base 210 facing the pressing block 220, and a mounting hole 232 is provided on the other. At least two positioning holes 231 are arranged around the rotation axis of the pressing block 220. The positioning member 230 includes the positioning hole 231 and the mounting hole 232, and also includes an elastic connecting portion 233 and a positioning portion 234, the elastic connecting portion 233 is arranged in the mounting hole 232, the positioning portion 234 is connected to one end of the elastic connecting portion 233, and one end of the positioning portion 234 away from the elastic connecting portion 233 is a convex curved surface. The positioning portion 234 can at least partially extend outside the mounting hole 232 and selectively be inserted into one of the positioning holes 231, so that the pressing block 220 is maintained at the first position or the second position.

[0037] Therefore, under the premise that the pressing block 220 is in the second position, the operation of loading a target onto the loading device 10 and locking the target with the loading member 100 is as follows: first, the target is placed on the carrying surface 101; then, an external force along the first direction is applied to the pressing block 220 in any appropriate manner to drive the pressing block 220 to rotate along the first direction, and when the pressing block 220 switches to the second position, the application of external force to the pressing block 220 is stopped. It can be understood that during the rotation of the pressing block 220 along the first direction, the positioning portion 234 is separated from the positioning hole 231 corresponding to the second position under the action of the convex surface, and the elastic connection portion 233 stores elastic potential energy. When the pressing block 220 reaches the first position, the elastic connection portion 233 releases the elastic potential energy and drives the positioning portion 234 to at least partially insert into the positioning hole 231 corresponding to the first position. It can be understood that when the pressing block 220 is switched to the first position and the external force applied to the pressing block 220 is cancelled, the pressing block 220 remains in the first position to continuously press against the target object, so that the target object is clamped in the slot formed by the pressing block 220 and the loading surface 101, thereby achieving the purpose of locking the target object on the loading member 100.

[0038] The operation of removing the target object from the loading device 10 is as follows: first, an external force is applied to the pressing block 220 in a second direction opposite to the first direction in any appropriate manner to drive the pressing block 220 to rotate in the second direction until the pressing block 220 deviates from the bearing surface 101 and returns to the second position, at which time the external force applied to the pressing block 220 is stopped; then the target object is removed from the bearing member 100. During the rotation of the pressing block 220 in the second direction, the positioning portion 234 firstly disengages from the positioning hole 231 corresponding to the first position under the action of the convex surface, and the elastic connection portion 233 stores elastic potential energy; when the pressing block 220 reaches the second position, the elastic connection portion 233 releases the elastic potential energy to allow the positioning portion 234 to be inserted into the positioning hole 231 corresponding to the second position.

[0039] That is, by rotating the pressing block 220, the three actions of releasing the previous positioning of the pressing block 220 and the base 210, adjusting the position of the pressing block 220 relative to the supporting surface 101, and repositioning the current positions of the pressing block 220 and the base 210 can be completed at one time, so that the pressing block 220 can be quickly switched between the first position and the second position, thereby making the disassembly and assembly operations of the target object simple and convenient.

[0040] It should be noted that, the “the pressing block 220 is partially arranged opposite to the bearing surface 101” mentioned herein means that when the pressing block 220 and the bearing surface 101 are projected onto a plane parallel to the bearing surface 101, the projection of the pressing block 220 partially overlaps with the projection of the bearing surface 101; “the pressing block 220 deviates from the bearing surface 101” means that when the pressing block 220 and the bearing surface 101 are projected onto a plane parallel to the bearing surface 101, the projection of the pressing block 220 is completely offset from the projection of the bearing surface 101. It can be understood that the rotation axis of the pressing block 220 is perpendicular to the bearing surface 101.

[0041] The present invention has no particular limitation on the target object. In some embodiments, the target object is a tip component in an instrument such as an immunoblotting detection device, a gene sequencer, a liquid transfer robot, an automated sample preparation system, a chemiluminescence instrument, etc. A person skilled in the art knows that the tip component includes a well plate and a liquid transfer tip inserted in at least part of the mounting holes of the well plate. In other embodiments, the target object is a well plate in an ELISA instrument.

[0042] Next, the detailed configuration of the loading device 10 is introduced by taking the example that the positioning hole 231 is provided on the surface of the base 210 facing the pressing block 220, and the mounting hole 232 passes through the pressing block 220. Those skilled in the art may modify the following description to adapt to the situation that the positioning hole 231 is provided on the surface of the pressing block 220 facing the base 210, and the mounting hole 232 is provided on the base 210.

[0043] The carrier 100 may have any suitable structure as long as it includes the carrying surface 101 for carrying the target. Figure 1 and Figure 2 As shown, the loading member 100 includes a plurality of side plates 110 connected end to end in sequence, and the end surfaces of all the side plates 110 located in the same plane together constitute the loading surface 101. Figure 1 In the embodiment, all the side panels 110 extend in the vertical direction, and the upper end surfaces of all the side panels 110 together constitute the bearing surface 101. It can be understood that the loading member 100 can also include a bottom plate 120, and the bottom plate 120 is connected to the lower ends of all the side panels 110 at the same time. In an alternative embodiment, the structure of the loading member 100 is still referred to Figure 1 and Figure 2 , including the side panels 110 and the bottom panel 120, but in an alternative embodiment, the surface of the bottom panel 120 located in the area enclosed by all the side panels 110 constitutes the bearing surface (not marked in the figure), that is, Figure 1In the orientation shown, the portion of the upper surface of the bottom plate 120 located on the inner side of the side plate 110 serves as the bearing surface.

[0044] The base 210 can be connected to one side of any of the side panels 110. In an exemplary embodiment, the base 210 partially protrudes from the end surface of the side panel 110 away from the bottom panel 120, and in a direction perpendicular to the bottom panel 120, the surface of the base 210 away from the bottom panel 120 forms a mounting surface 211 for mounting the pressing block 220. In other words, Figure 1 In the orientation shown, the upper surface of the base 210 is used as the mounting surface 211, and in the vertical direction, the mounting surface 211 is located above the bearing surface 101, and in the horizontal direction, the mounting surface 211 is offset from the bearing surface 101. In this way, when the pressing block 220 is installed on the mounting surface 211 and partially arranged opposite to the bearing surface 101, the clamping groove is formed between the pressing block 220 and the bearing surface 101.

[0045] In an alternative embodiment, the mounting surface of the base is flush with the bearing surface. The pressing block includes a joint portion and a pressing portion, and the joint portion protrudes from the pressing portion (not shown in the figure). The joint portion is connected to the mounting surface, and in a direction perpendicular to the mounting surface, the distance from the pressing portion to the mounting surface is greater than zero. When the pressing block is in the first position, the pressing portion is at least partially arranged opposite to the bearing surface, and the card slot is formed between the pressing portion and the bearing surface.

[0046] The pressing block 220 is rotatably connected to the base 210 in any suitable manner. Figures 3 to 5As shown, the pressing block 220 is provided with a first docking hole 221, and the first docking hole 221 penetrates the pressing block 220 along the arrangement direction of the pressing block 220 and the base 210. The first docking hole 221 includes an axially connected first hole segment 221a and a second hole segment 221b, and the second hole segment 221b is closer to the base 210 than the first hole segment 221a. The aperture of the first hole segment 221a is larger than the aperture of the second hole segment 221b, and the junction of the first hole segment 221a and the second hole segment 221b forms a first step surface 221c. The base 210 is provided with a second docking hole 212, and the aperture of the second docking hole 212 is smaller than the aperture of the second hole segment 221b. The second docking hole 212 is coaxially arranged with the first docking hole 221 and communicates with each other. The locking mechanism 200 also includes a coupling assembly, and the coupling assembly includes an axially connected first segment 241, a second segment 242 and a third segment 243. The first segment 241 is inserted into the second docking hole 212 and connected to the base 210. The second segment 242 is partially inserted into the second hole segment 221b, and the outer diameter of the second segment 242 is larger than the aperture of the second docking hole 212 and smaller than the aperture of the second hole segment 221b. A second step surface (not marked in the figure) is formed at the junction of the second segment 242 and the first segment 241, and the second step surface abuts against the surface of the base 210 facing the pressing block 220. The third segment 243 is at least partially inserted into the first hole segment 221a, and the distance from the third segment 243 to the first step surface 221c is greater than zero. At the junction of the third segment 243 and the second segment 242, the outer diameter of the third segment 243 is larger than the aperture of the second hole segment 221b and smaller than the aperture of the first hole segment 221a. Therefore, through the cooperation of the joint assembly, the first docking hole 221 and the second docking hole 212 , a rotatable connection between the pressing block 220 and the base 210 is achieved.

[0047] For more specific implementations, please refer to Figure 4 and Figure 5, the joint assembly includes a spacer 244, a gasket 245 and a joint piece 246. The axial length of the spacer 244 is greater than the axial length of the second hole section 221b. A portion of the spacer 244 is coaxially arranged in the second hole section 221b and abuts against the surface of the base 210 close to the pressing block 220. Another portion of the spacer 244 protrudes from the first step surface 221c and is located in the first hole section 221a. The spacer 244 and the second hole section 221a are in clearance fit. The outer diameter of the gasket 245 is greater than the outer diameter of the spacer 244. A portion of the gasket 245 contacts the surface of the spacer 244 at one end away from the base 210, and another portion is located on the side of the first step surface 221c away from the base 210. The engaging member 246 includes a head 246a and an engaging rod 246b, wherein the engaging rod 246b partially passes through the gasket 245 and the first docking hole 221 and extends into the second docking hole 212, and is connected to the base 210, and the head 246a is pressed against the gasket 245. It can be understood that the limiting line between the engaging member 246 and the gasket 245 prevents the pressing block 220 from being separated from the base 210. In an exemplary embodiment, the second docking hole 212 is a threaded hole, the engaging member 246 is a screw, and the engaging rod 246b is threadedly connected to the second docking hole 212.

[0048] The portion of the engaging rod 246b located in the second docking hole 212 constitutes the first segment 241; the portion of the engaging rod 246b corresponding to the gasket 245, the gasket 245 and the head 246a constitute the third segment 243, and the outer diameter of the third segment 243 at the junction with the second segment 242 is the outer diameter of the gasket 245; the portion of the engaging rod 246 located between the gasket 245 and the second docking hole 212, and the spacer 241 constitute the second segment 242, and the surface of the spacer 241 facing the base 210 constitutes the second step surface.

[0049] It can be understood that based on the arrangement of the first docking hole 221 , the second docking hole 212 , and the spacer 241 , the rotation axis of the pressing block 220 can be considered to be the axis of the first docking hole 221 , the second docking hole 212 , and the spacer 241 .

[0050] Please refer to Figure 5At least two positioning holes 231 are provided on the surface of the base 210 facing the pressing block 220. When the at least two positioning holes 231 are arranged in sequence around the rotation axis of the pressing block 220, two adjacent positioning holes 231 may partially overlap or may be arranged at intervals (not shown in the figure), which is not limited in this embodiment of the utility model.

[0051] Taking the case where the number of the positioning holes 231 provided on the base 210 is two as an example, the two positioning holes 231 are respectively a first positioning hole and a second positioning hole (not marked in the figure), and the first positioning hole is closer to the bearing surface 101 than the second positioning hole. When the pressing block 220 is in the first position, the positioning portion 234 is at least partially inserted into the first positioning hole, and when the pressing block 220 is in the second position, the positioning portion 234 is at least partially inserted into the second positioning hole.

[0052] Therefore, during the movement of the pressing block 220 from the first position to the second position, the positioning portion 234 rotates along the first direction around the axis of the second docking hole 212 together with the pressing block 220, and under the action of the convex surface, the positioning portion 234 first moves along the direction of the base 210 pointing to the pressing block 220 to disengage from the first positioning hole and squeeze the elastic connection portion 233, so that the elastic connection portion 233 stores elastic potential energy. When the positioning portion 234 continues to rotate along the first direction around the axis of the second docking hole 212 with the pressing block 220 and reaches the position of the second positioning hole, the elastic connection portion 233 releases the elastic potential energy and drives the positioning portion 234 along the direction of the pressing block 220 pointing to the base 210, so that the positioning portion 234 is at least partially inserted into the second positioning hole.

[0053] Conversely, when the locking mechanism 200 moves from the second position to the first position, the positioning portion 234 rotates along the second direction along the axis of the second docking hole 212 with the pressing block 220, and under the action of the convex surface, the positioning portion 234 first moves in the direction of the base 210 pointing to the pressing block 220 to disengage from the second positioning hole and squeeze the elastic connection portion 233, so that the elastic connection portion 233 stores elastic potential energy. When the positioning portion 234 continues to rotate along the second direction along the axis of the second docking hole 212 with the pressing block 220 and reaches the position of the first positioning hole, the elastic connection portion 233 releases the elastic potential energy and drives the positioning portion 234 along the direction of the pressing block 220 pointing to the base 210, so that the positioning portion 234 is at least partially inserted into the first positioning hole.

[0054] In a preferred embodiment, the positioning portion 234 is a part of a sphere, where the sphere can be a sphere or an ellipsoid, and the positioning portion 234 can be a hemisphere. Furthermore, the elastic connecting portion 233 and the positioning portion 234 are part of a ball plunger. In other words, the positioning member 230 includes a ball plunger, and the ball plunger includes the elastic connecting portion 233 and the positioning portion 234. It should be understood that when the ball plunger is assembled to the mounting hole 232, the non-ball part of the ball plunger should not protrude from the mounting hole 232 to prevent it from interfering with the rotation of the pressing block 220.

[0055] Furthermore, if Figure 6 and Figure 7 As shown, the surface of the pressing block 220 facing the base 210 is at least partially formed as a pressing surface 222. When the locking mechanism 200 is in the first state, the pressing surface 222 is at least partially arranged opposite to the bearing surface 101. The pressing surface 222 is inclined relative to the bearing surface 101, and in a direction perpendicular to the bearing surface 101, the distance from the pressing surface 222 to the base 210 gradually increases along the direction from the edge of the pressing block 220 to the rotation axis of the pressing block 220.

[0056] In an exemplary embodiment, the pressing block 220 is a rectangular block and includes a first surface, a second surface and a plurality of third surfaces (not marked in the figure), wherein the first surface faces the base 210. The second surface is away from the base 210. The plurality of third surfaces are connected end to end in sequence and also connect the first surface and the second surface. The first surface partially forms the pressing surface 222, and the pressing surface 222 is a right triangle. The two right-angled sides of the right triangle are respectively located on two adjacent third surfaces, so that the right-angled vertex of the right triangle is located at the intersection of the two adjacent third surfaces. The hypotenuse of the right triangle is closer to the rotation axis of the pressing block 220 than its right-angled vertex. The distance from the pressing surface 222 to the base 210 gradually increases along the direction from the right-angled vertex of the right triangle to the hypotenuse.

[0057] Corresponding to the arrangement of the pressing surface 222, the number of the positioning holes 231 is more than two, for example, three, four, five or even more. Through the cooperation of the plurality of positioning holes 231 and the pressing surface 222, the locking mechanism 200 can lock the target objects of different thicknesses onto the carrier 100. The thickness of the target object refers to the size of the target object in a direction perpendicular to the carrying surface 101 when the target object is placed on the carrying surface 101.

[0058] Assuming that the number of the positioning holes 231 arranged on the base 210 is N, and N is a positive integer greater than 2, then all the positioning holes 231 are numbered sequentially along the direction away from the bearing surface 101, namely the first positioning hole, the second positioning hole, the third positioning hole...the N-1th positioning hole, the Nth positioning hole. When the positioning portion 234 is at least partially inserted into the Nth positioning hole, the pressing block 220 is in the second position, and when the positioning hole 233 is at least partially inserted into any other positioning hole 231, the pressing block 220 is in the first position. In other words, the first position has a plurality of different sub-positions, namely the first sub-position, the second sub-position, the third sub-position...the N-1th sub-position. When the positioning portion 234 is inserted into the first positioning hole, the pressing block 220 is in the first sub-position. When the positioning portion 234 is inserted into the second positioning hole, the pressing block 220 is in the second sub-position. When the positioning portion 234 is inserted into the third positioning hole, the pressing block is in the third sub-position...When the positioning portion 234 is inserted into the N-1th positioning hole, the pressing block 220 is in the N-1th sub-position.

[0059] It can be understood that when the pressing block 220 rotates along the second direction from the second position, as the rotation angle of the pressing block 220 along the second direction increases, the portion of the pressing surface 222 arranged relative to the bearing surface 101 increases, and the minimum distance from the pressing surface 222 to the bearing surface 101 also increases. At the same time, the positioning portion 234 sequentially enters the N-1th positioning hole, then leaves the N-1th positioning hole, enters the N-2th positioning hole, leaves the N-2th positioning hole... enters the third positioning hole, leaves the third positioning hole, enters the second positioning hole, leaves the second positioning hole, and enters the first positioning hole. In other words, when the pressing block 220 rotates along the second direction, the pressing block 220 can be switched to the N-1th sub-position, the N-2th sub-position, ... the third sub-position, the second sub-position and the first sub-position in sequence, and when the pressing block 220 is in different sub-positions, the minimum distance from the pressing surface 222 to the bearing surface 101 is different, so that the thickness of the target object that can be pressed by the pressing block 220 is also different.

[0060] In practice, when the pressing block 220 switches from the first position to the second position, it is expected that the pressing block 220 cannot continue to rotate along the first direction after the positioning portion 234 is at least partially inserted into the first positioning hole; when the pressing block 220 switches from the second position to the first position, if the number of the positioning holes 231 is two, it is expected that the rotating block 220 cannot continue to rotate along the second direction after the positioning portion 234 is at least partially inserted into the second positioning hole; if the number of the positioning holes 231 is N which is a plurality of two, it is expected that the rotating block 220 cannot continue to rotate along the second direction after the positioning portion 234 is at most partially inserted into the Nth positioning hole.

[0061] Therefore, please refer back to Figures 3 to 5 The locking mechanism 200 further includes a stopper 250, which is used to limit the rotation angle of the pressing block 220 to be less than or equal to a predetermined angle, and the predetermined angle is related to the distance between the two positioning holes 231 that are farthest apart. A first straight line and a second straight line are defined, wherein the first straight line is perpendicular to and intersects with the rotation axis of the pressing block 220, and is also perpendicular to and intersects with the axis of the first designated positioning hole 231, and the second straight line is perpendicular to and intersects with the rotation axis of the pressing block 220, and is also perpendicular to and intersects with the axis of the second designated positioning hole 231. The first designated positioning hole 231 and the second designated positioning hole 231 are the two positioning holes 231 that are farthest apart. Specifically, the first designated positioning hole 231 refers to the first positioning hole, and when the number of the positioning holes 231 is two, the second designated positioning hole 231 refers to the second positioning hole; when the number of the positioning holes 231 is more than two, the second designated positioning hole 231 refers to the Nth positioning hole. The predetermined angle is equal to an angle β formed by the intersection of the first straight line and the second straight line.

[0062] Optionally, the limiting member 250 includes a limiting groove 251 and a limiting pin 252, wherein the limiting groove 251 is provided on one of the pressing block 220 and the base 210, and the limiting pin 252 is provided on the other of the pressing block 220 and the base 210. The limiting groove 251 extends around the rotation axis of the pressing block 220. The limiting pin 252 is partially inserted in the limiting groove 251, and slides in the limiting groove 251 as the pressing block 220 rotates. It should be understood that the angle of the central angle α corresponding to the limiting groove 251 is determined according to the angle of the included angle β and the size of the limiting pin 252, as long as the maximum stroke of the limiting pin 252 when sliding in the limiting groove 251 is equal to the angle of the included angle β.
