[0038] See also Figure 1 The present application provides a centrifugal device 1, which is used to perform centrifugal processing steps on sample tubes. The centrifugal device 1 has a sample tube buffer area, an adapter buffer area, a loading area, a centrifugal area and an unloading area, and the centrifugal device 1 includes an adapter 10, two groups of grabbing components 20, a loading seat, a centrifuge and an unloading seat, the loading seat is located in the loading area, the centrifuge is located in the centrifugal area, and the unloading seat is located in the unloading area. One group of grabbing components 20 is used to drive the adapter 10 to transfer from the adapter buffer area to the loading seat located in the loading area, and can also drive the sample tube located in the sample tube buffer area to the adapter 10 located in the loading area. When the adapter 10 in the loading seat is balanced, one group of grabbing components 20 can also drive the adapter 10 from the loading area to the centrifuge in the centrifugal area for centrifugation. After centrifugation, another group of grabbing components 20 is used to drive the adapter 10 from the centrifuge in the centrifugal area to the unloading seat in the unloading area to facilitate the sample tube to perform subsequent processing steps.
[0039] The structures and working principles of the two grabbing components 20 are completely the same.
[0040] Please refer again Figure 1 , and also see Figure 2 , Figure 3 , Figure 4 and Figure 5 The adapter 10 includes a base 11 and a lifting member 12. The lifting member 12 includes a main body 121 and at least two lifting members 122. The main body 121 is disposed on the base 11. All the lifting members 122 are protrudingly disposed at one end of the main body 121 away from the base 11 and are spaced around the circumference of the main body 121. The gripping assembly 20 includes two clamping jaws 21 disposed opposite to each other. Two inner side surfaces of the two clamping jaws 21 disposed opposite to each other are protrudingly disposed with protrusions 211. The protrusions 211 are provided with grooves 215. The grooves 215 are used to buckle with the lifting members 122 of the lifting member 12.
[0041] During actual assembly, the two clamping jaws 21 of the grabbing assembly 20 are arranged opposite to each other, and the two opposite lifting portions 122 of the lifting member 12 of the adapter 10 are respectively inserted into the grooves 215 of the two clamping jaws 21 and matched.
[0042] Specifically, the loading seat, the centrifuge and the unloading seat all have grooves for placing the adapter 10, and the shape of the grooves matches the shape of the base 11 of the adapter 10. In general, the base 11 of the adapter 10 and the grooves are non-cylindrical, so that the adapter 10 placed in the grooves will hardly rotate relative to the grooves, ensuring the stability of the placement of the adapter 10. However, for this reason, the adapter 10 cannot rotate during the process of being captured and transferred by the capture assembly 20, so as to ensure that the adapter 10 can be aligned and placed in the groove.
[0043] By setting the groove 215 on the clamping jaw 21, the lifting part 122 on the lifting component 12 cooperates with the groove 215, and the groove 215 has a limiting effect on the lifting part 122, and the limiting is reliable, so that the possibility of the adapter 10 shaking and rotating relative to the grasping component 20 is reduced, so that the subsequent adapter 10 can be aligned and placed in the groove of the loading seat, centrifuge or unloading seat, thereby improving the accuracy of the placement of the adapter 10 and making the centrifuge 1 work more reliable.
[0044] Furthermore, the surface of the main body 121 connected between each adjacent two lifting parts 122 is constructed as an arc surface 111, and the protrusion 211 of the clamp 21 has two arc surfaces 212 arranged at intervals along the width direction of the groove 215. The curvature of the arc surface 212 of the protrusion 211 is the same as the curvature of the arc surface 111 of the main body 121 and the curvature of the side of the sample tube, and the two arc surfaces 212 on the protrusion 211 define a clamping port 213 connected to the groove 215, and the clamping port 213 is used to clamp the sample tube or the main body 121.
[0045] When the grasping assembly 20 grasps the sample tube, the two clamping jaws 21 of the grasping assembly 20 are located on both sides of the sample tube, and the arc surface 212 of the clamping jaws 21 fits with the side surface of the sample tube, so that the sample tube can be clamped between the two clamping openings 213.
[0046] The specific process of the grabbing assembly 20 grabbing the sample tube is as follows: the two clamping jaws 21 of the grabbing assembly 20 are opened and moved down to a position corresponding to the tube body of the sample tube, and then the two clamping jaws 21 are closed so that the tube body of the sample tube can be clamped between the two clamping openings 213 to achieve the fixation of the grabbing assembly 20 and the sample tube. Afterwards, the grabbing assembly 20 grabs the sample tube and changes its position to place the sample tube in the adapter 10.
[0047] When the grasping assembly 20 grasps the adapter 10, the two clamping jaws 21 of the grasping assembly 20 are located on both sides of the lifting part 12 of the adapter 10, and the groove 215 on the clamping jaw 21 cooperates with the lifting portion 122 on the lifting part 12. In addition, the arc surface 212 on the clamping jaw 21 fits with the arc surface 111 adjacent to and connected to the lifting portion 122 inserted into the groove 215, so that the lifting part 12 of the adapter 10 can be clamped between the two clamping openings 213.
[0048] The specific process of the grabbing assembly 20 grabbing the adapter 10 is as follows: the two clamping jaws 21 of the grabbing assembly 20 are opened and moved down to the bottom of the lifting portion 122, and then the two clamping jaws 21 are closed and moved up again, so that the lifting portion 122 can be buckled into the groove 215, and the main body 121 is clamped between the two clamping openings 213, so as to achieve the fixation of the grabbing assembly 20 and the adapter 10. Afterwards, the grabbing assembly 20 grabs the adapter 10 and changes its position to place the adapter 10 in the loading area, the centrifugal area, or the unloading area.
[0049] It can be seen that by connecting the main body 121 to the surface between each adjacent two lifting parts 122 as a circular arc surface 111, the circular arc surface 111 on the main body 121 has the same curvature as the side surface of the sample tube. The circular arc surface 111 can simulate the way in which the sample tube is grasped, so that the main body 121 and the sample tube can be clamped in the clamping port 213 to be grasped by the grasping component 20, and the grasping is convenient and reliable.
[0050] In addition, the two arc surfaces 212 on the clamping jaw 21 cooperate to form a clamping opening 213 with a gradually varying width, thereby being able to clamp sample tubes with different radial sizes.
[0051] In some optional embodiments of the present application, the protrusion 211 of the clamp 21 has two connecting surfaces 214 spaced apart along the width direction of the groove 215, the connecting surface 214 of the protrusion 211 is connected between the top surface of the protrusion 211 and the arc surface 212, and the connecting surface 214 is an inclined surface inclined downward.
[0052] Therefore, when the two clamping jaws 21 are slightly misaligned and misaligned with the adapter 10 or the sample tube, the clamping jaws 21 may hook the lifting portion 122 of the adapter 10 or the tube cover of the sample tube when the clamping jaws 21 move upward. Since the connecting surface 214 is an inclined surface arranged to be inclined downward, the lifting portion 122 of the adapter 10 or the tube cover of the sample tube can slide down along the connecting surface 214 when the clamping jaws 21 move upward, thereby ensuring the reliability of the separation of the clamping jaws 21 from the adapter 10 or the sample tube.
[0053] In some optional embodiments of the present application, the top surface of the lifting portion 122 of the present application is an inclined surface that is tilted downward. Therefore, when the two clamping jaws 21 and the adapter 10 are slightly misaligned and not centered, the clamping jaw 21 may move downward and the clamping jaw 21 may press against the top surface of the lifting portion 122. Since the top surface of the lifting portion 122 is an inclined surface that is tilted downward, the clamping jaw 21 can slide down to the bottom of the lifting portion 122 along the tilt direction of the top surface to ensure that the groove 215 on the subsequent clamping jaw 21 can cooperate with the lifting portion 122.
[0054] It is worth mentioning that, for the convenience of distinction and labeling, the top surface of the lifting portion 122 is defined as a lifting top surface 123 .
[0055] In some optional embodiments of the present application, in the direction from the inside to the outside of the main body 121, the width of the lifting portion 122 (eg Figure 3 H in the figure). During the cooperation between the lifting portion 122 and the groove 215, the width direction of the groove 215 is substantially the same as the width direction of the lifting portion 122. In the direction from the inside to the outside of the main body 121, the width of the lifting portion 122 gradually decreases, so that the width of the lifting portion 122 at each position in the direction from the inside to the outside of the main body 121 is basically slightly smaller than the width of the groove 215. In this way, even if the groove 215 is slightly offset from the lifting portion 122 in the width direction, the groove 215 can still be engaged with the lifting portion 122, which is conducive to improving the reliability of the grasping of the grasping assembly 20.
[0056] Please refer again Figure 2 and Figure 3 , and also see Figure 6 and Figure 7 In some optional embodiments of the present application, the base 11 has a plurality of placement holes 112, and all the placement holes 112 are arranged in an array to form a plurality of rows and columns. The placement holes 112 in each row are arranged vertically with the placement holes 112 in each column.
[0057] The placement hole 112 is used to place and carry the sample tube.
[0058] Combination Figure 6 and Figure 7 ,exist Figure 6 and Figure 7 In the embodiment, each row of placement holes 112 is arranged along the X direction, and each column of placement holes 112 is arranged along the Y direction.
[0059] By providing a plurality of placement holes 112 arranged in an array, the number of placement holes 112 can be increased, thereby facilitating increasing the loading capacity of the sample tube.
[0060] In some optional embodiments of the present application, the lifting member 12 is arranged at the center of the array, and the lifting portions 122 are arranged in pairs, and the lifting portions 122 include at least one pair and at most two pairs, and each pair of lifting portions 122 is arranged at an oblique interval along the extension direction of the row passing through the center of the array and the extension direction of the column passing through the center of the array at an equal angle, and different pairs of lifting portions 122 are distributed along different oblique directions on opposite sides of the main body 121. Figure 6 and Figure 7 ,exist Figure 6 and Figure 7 The oblique direction is L 1 Dashed line or L 2 Direction shown by dotted line.
[0061] Along the extension direction of the row passing through the center of the array and the extension direction of the column passing through the center of the array, the gap between the two placement holes 112 obliquely arranged on the opposite sides of the main body 121 and intersecting at equal angles will be larger. When the clamping jaw 21 cooperates with the two lifting parts 112 obliquely distributed on the opposite sides of the main body 121, interference between the clamping jaw 21 and the sample tubes in the two placement holes 112 located in the oblique direction and on both sides of the main body 121 can be avoided, thereby ensuring the reliability of the grasping adapter 10.
[0062] In some optional embodiments of the present application, the base 11 also includes a row of weight-reducing holes 113 between each two adjacent rows of placement holes 112, and all weight-reducing holes 113 in each row of weight-reducing holes 113 and all placement holes 112 in each adjacent row of placement holes 112 are arranged in the same direction and alternately. The provision of the weight-reducing holes 113 can reduce the weight of the adapter 10 and facilitate the flexible transportation of the adapter 10 by the grabbing assembly 20. In addition, all weight-reducing holes 113 in each row of weight-reducing holes 113 and all placement holes 112 in each adjacent row of placement holes 112 are arranged in the same direction and alternately, so that an interspaced arrangement is formed between the weight-reducing holes 113 and the placement holes 112, thereby maintaining the mechanical strength of the adapter 10.
[0063] Please refer again Figure 2 , and also see Figure 8 In some optional embodiments of the present application, the adapter 10 further includes an elastic member 13, and the elastic member 13 corresponds to the placement hole 112 one by one. The elastic member 13 includes an elastic ring 131 and a plurality of elastic legs 132 arranged along the circumference of the elastic ring 131. The elastic ring 131 of the elastic member 13 is installed at the opening of the placement hole 112, and all the elastic legs 132 extend into the placement hole 112. When the grab assembly 20 loads the sample tube, the sample tube passes through the elastic ring 131 and extends into the placement hole 112, and is clamped between the elastic legs 132.
[0064] The elastic member 13 can not only adapt to sample tubes of different diameters, but also clamp the sample tubes, which helps to improve the stability and reliability of sample tube transportation and prevent the sample tubes from flying out of the adapter 10 during the centrifugation process.
[0065] In the adapter 10 and the centrifugal device 1, the lifting member 12 of the adapter 10 is provided with a lifting portion 122, which is used to engage with the groove 215 on the clamping claw 21 of the grabbing assembly 20, so that the lifting portion 122 can be limited in the groove 215, and then, the possibility of the adapter 10 shaking and rotating relative to the grabbing assembly 20 is reduced, so that the subsequent adapter 10 can be aligned with its placement position, the accuracy of the placement of the adapter 10 is improved, and the operation is more reliable. In addition, the arc surface 111 on the main body 121 can simulate the way the sample tube is grabbed, so that the main body 121 can be easily grabbed.
[0066] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0067] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
