The fixed joint is located on the support base and is used to insert into the magnetic rod sleeve.

The push sleeve assembly is movably mounted on the bearing base in the vertical direction. Both ends of the push sleeve assembly in the vertical direction can abut against the magnetic rod fixing plate and the magnetic rod sleeve respectively.

During this process, since the magnetic rod body is elastically mounted on the magnetic rod fixing plate in the vertical direction, there is a buffer between the magnetic rod body and the magnetic rod sleeve. Therefore, when the magnetic rod body and the push sleeve assembly descend simultaneously, the magnetic rod body will not be damaged or even broken, thus preventing damage to the magnetic rod sleeve unloading device.

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figures 1-4 As shown, this embodiment provides a magnetic rod sleeve removal and removal device for installing or removing the magnetic rod sleeve 5.

[0033] The magnetic rod sleeve unloading device includes a support base 1, a magnetic rod moving mechanism 2, a fixed joint 3, and a push sleeve assembly 4. The magnetic rod moving mechanism 2 includes a drive assembly 21, a magnetic rod fixing plate 22, and a magnetic rod body 23. The drive assembly 21 is mounted on the support base 1, and the magnetic rod body 23 is elastically mounted on the magnetic rod fixing plate 22 in the vertical direction. The drive end of the drive assembly 21 is connected to the magnetic rod fixing plate 22 and is used to drive the magnetic rod fixing plate 22 to move in the vertical direction. Thus, under the drive of the magnetic rod fixing plate 22, the magnetic rod body 23 can also move in the vertical direction. The fixed joint 3 is mounted on the support base 1 and is used to insert into the magnetic rod sleeve 5. The magnetic rod body 23 can pass through the fixed joint 3 and be located inside the magnetic rod sleeve 5. Thus, under the drive of the drive assembly 21, the magnetic rod body 23 can extend into the magnetic rod sleeve 5 to achieve magnetization and can also retract to the outside of the magnetic rod sleeve 5 to achieve demagnetization.

[0034] Specifically, a linear guide rail 13 extending vertically is provided on the support base 1, and the magnetic rod fixing plate 22 is slidably disposed on the linear guide rail 13. The linear guide rail 13 improves the stability and reliability of the magnetic rod fixing plate 22 and the magnetic rod body 23 during movement. Optionally, the drive assembly 21 is a lead screw motor, and the magnetic rod fixing plate 22 is fixedly connected to the lead screw motor via a nut. Of course, the drive assembly 21 can also be other mechanisms with driving capabilities; this embodiment does not impose specific limitations.

[0035] The push sleeve assembly 4 is movably mounted on the bearing base 1 in the vertical direction. Both ends of the push sleeve assembly 4 in the vertical direction can abut against the magnetic rod fixing plate 22 and the magnetic rod sleeve 5 respectively. When the drive assembly 21 drives the magnetic rod fixing plate 22 to descend, the magnetic rod fixing plate 22 can abut against and push the push sleeve assembly 4, causing the push sleeve assembly 4 to move downward and contact the magnetic rod sleeve 5, ultimately achieving the separation of the magnetic rod sleeve 5 from the fixed joint 3. During this process, since the magnetic rod body 23 is elastically mounted on the magnetic rod fixing plate 22 in the vertical direction, there is a buffer between the magnetic rod body 23 and the magnetic rod sleeve 5. Therefore, when the magnetic rod body 23 and the push sleeve assembly 4 descend simultaneously, the magnetic rod body 23 will not be damaged or even broken, causing damage to the magnetic rod sleeve unloading device.

[0036] like Figure 1 and Figure 2 As shown, the magnetic rod moving mechanism 2 also includes a pressure plate 24 and a first compression spring 25. The pressure plate 24 is disposed on the magnetic rod fixing plate 22. One end of the magnetic rod body 23 is provided with a stop part 231. The other side of the magnetic rod body 23 away from the stop part 231 passes through the magnetic rod fixing plate 22. The first compression spring 25 is disposed between the pressure plate 24 and the stop part 231. By disposing the stop part 231 of the magnetic rod body 23 between the pressure plate 24 and the magnetic rod fixing plate 22, it is possible to prevent the magnetic rod body 23 from detaching during the rising or falling process. Furthermore, by disposing the first compression spring 25 between the pressure plate 24 and the stop part 231, the magnetic rod body 23 can be buffered relative to the magnetic rod fixing plate 22, thereby achieving buffering between the magnetic rod body 23 and the magnetic rod sleeve 5.

[0037] Furthermore, the magnetic rod body 23 and the fixing connector 3 are both comprised of several units. Several magnetic rod bodies 23 are spaced apart on the magnetic rod fixing plate 22 in the horizontal direction, and several fixing connectors 3 are spaced apart on the bearing base 1 in the horizontal direction. The several magnetic rod bodies 23 and several fixing connectors 3 are arranged in a one-to-one correspondence. Thus, the magnetic rod sleeve unloading device can load and unload multiple single magnetic rod sleeves 5, which is suitable for low-throughput nucleic acid extraction and has a low cost for nucleic acid extraction. Since the magnetic rod body 23 and the magnetic rod fixing plate 22 are elastically connected, each magnetic rod body 23 can reach the bottom of the corresponding magnetic rod sleeve 5 when magnetically attracted, thereby ensuring that the magnetic attraction state of different magnetic rod sleeves 5 is consistent.

[0038] like Figure 1 and Figure 4 As shown, one end of the fixed connector 3 is provided with a plug-in portion 31. The plug-in portion 31 has an annular protrusion 311 protruding circumferentially. The plug-in portion 31 can be interference-fitted into the magnetic rod sleeve 5 through the annular protrusion 311. The annular protrusion 311 improves the connection stability between the fixed connector 3 and the magnetic rod sleeve 5. Optionally, there are at least two annular protrusions 311. At the same time, the fixed connector 3 is provided with a positioning boss 32. When the plug-in portion 31 is inserted into the magnetic rod sleeve 5, the positioning boss 32 can abut against the end of the magnetic rod sleeve 5 in the vertical direction. Thus, when the plug-in portion 31 is inserted into the magnetic rod sleeve 5, the positioning boss 32 can limit the insertion depth of the fixed connector 3 to meet the actual installation requirements.

[0039] like Figure 1 and Figure 3As shown, the bearing base 1 is connected to a connector mounting seat 11. The connector mounting seat 11 has a mounting cavity. One end of the fixed connector 3 is movably disposed in the mounting cavity in the vertical direction, and the other end of the fixed connector 3 passes through the connector mounting seat 11. A second compression spring 12 is also provided in the mounting cavity. The second compression spring 12 is disposed between the bearing base 1 and the fixed connector 3, so that the fixed connector 3 is elastically disposed in the connector mounting seat 11 in the vertical direction. Thus, when the magnetic rod sleeve unloading device descends as a whole and the fixed connector 3 is inserted into the magnetic rod sleeve 5, there is a buffer between the fixed connector 3 and the magnetic rod sleeve 5, so as to prevent excessive movement and damage to the magnetic rod sleeve 5 during the insertion process. Moreover, when facing the insertion of several fixed connectors 3 and several magnetic rod sleeves 5, it can also offset the state differences when different fixed connectors 3 are inserted into the magnetic rod sleeves 5, ensuring that each fixed connector 3 can be successfully inserted into the corresponding magnetic rod sleeve 5.

[0040] Furthermore, the push sleeve assembly 4 includes a guide rod 41 and a push plate 42. The guide rod 41 is movably mounted on the bearing base 1 in the vertical direction. One end of the guide rod 41 can abut against the magnetic rod fixing plate 22, and the other end of the guide rod 41 is connected to the push plate 42. The push plate 42 can abut against the magnetic rod sleeve 5. Thus, during the process of the drive assembly 21 driving the magnetic rod fixing plate 22 to lower the magnetic rod body 23, the magnetic rod body 23 can first extend into the magnetic rod sleeve 5 to achieve magnetization. When it is necessary to remove the magnetic rod sleeve 5, the drive assembly 21 can drive the magnetic rod fixing plate 22 to continue to lower, so that the magnetic rod fixing plate 22 contacts and pushes the guide rod 41, thereby causing the push plate 42 to contact and push the magnetic rod sleeve 5, and finally realizing the separation of the magnetic rod sleeve 5 from the fixed joint 3.

[0041] Optionally, the pusher assembly 4 further includes a third compression spring 43, which is sleeved on the guide rod 41. The two ends of the third compression spring 43 abut against the bearing base 1 and the end of the guide rod 41, respectively, to drive the push plate 42 to always move away from the magnetic rod sleeve 5. Thus, after the push plate 42 pushes the magnetic rod sleeve 5 away from the fixed joint 3, the drive assembly 21 drives the magnetic rod fixing plate 22 to rise. At this time, the third compression spring 43 can return the push plate 42 to its original position, facilitating the subsequent insertion of the fixed joint 3 into the magnetic rod sleeve 5. Further optionally, the push plate 42 is sleeved on the fixed joint 3, which improves the stability of the push plate 42 during movement and allows it to push the circumferential outer periphery of the magnetic rod sleeve 5, thereby reducing the difficulty of detaching the magnetic rod sleeve 5 from the fixed joint 3.

[0042] The magnetic rod sleeve unloading device in this embodiment includes six working states: before inserting the magnetic rod sleeve 5, when inserting the magnetic rod sleeve 5, after inserting the magnetic rod sleeve 5, when attracting magnets, when demagnetizing, and when demagnetizing the magnetic rod sleeve 5.

[0043] Before inserting the magnetic rod sleeve 5, the second compression spring 12 inside the connector mounting base 11 is in a pre-compression state. The drive assembly 21 controls the magnetic rod fixing plate 22 to rise to the high position, the first compression spring 25 returns to the pre-compression state, the magnetic rod body 23 rises and retracts into the fixed connector 3, the third compression spring 43 returns to the pre-compression state, and the push plate 42 is in contact with the bottom of the bearing base 1.

[0044] When the magnetic rod sleeve 5 is inserted, the entire magnetic rod sleeve removal device moves downward, and the fixed connector 3 is slowly inserted into the magnetic rod sleeve 5 until the positioning boss 32 of the fixed connector 3 contacts the upper edge of the magnetic rod sleeve 5. During this process, the second compression spring 12 inside the connector mounting base 11 will be compressed to varying degrees, thereby offsetting the differences in the state when different fixed connectors 3 are inserted into and removed from the magnetic rod sleeve 5, ensuring that each fixed connector 3 successfully removes the magnetic rod sleeve 5, wherein the fixed connector 3 and the magnetic rod sleeve 5 are interference-fitted.

[0045] After the magnetic rod sleeve 5 is inserted, the magnetic rod sleeve unloading device rises to a certain height, and the second compression spring 12 inside the connector mounting base 11 returns to the pre-compression state.

[0046] During magnetization, the drive assembly 21 controls the magnetic rod fixing plate 22 to move downwards. The magnetic rod body 23 extends from inside the fixing joint 3 and slowly inserts into the magnetic rod sleeve 5 until the bottom of each magnetic rod body 23 contacts the bottom of the magnetic rod sleeve 5. At the same time, the first compression spring 25 is slightly compressed to ensure that the bottom of each magnetic rod body 23 contacts the bottom of the magnetic rod sleeve 5. At this time, the magnetic rod fixing plate 22 has pressed the guide rod 41 and the push plate 42 downwards a certain distance, but the push plate 42 has not yet contacted the magnetic rod sleeve 5.

[0047] During demagnetization, the magnetic rod body 23 moves upward along with the magnetic rod fixing plate 22, and the magnetic rod body 23 slowly retracts into the fixed joint 3, leaving the magnetic rod body 23 completely inside the magnetic rod sleeve 5.

[0048] When the magnetic rod sleeve 5 is removed, the drive assembly 21 controls the magnetic rod fixing plate 22 to move downward. The magnetic rod body 23 extends out from inside the fixing joint 3 and slowly inserts into the magnetic rod sleeve 5. First, the first compression spring 25 is compressed, and the bottom of each magnetic rod body 23 contacts the bottom of the magnetic rod sleeve 5. At the same time, the magnetic rod fixing plate 22 has pressed the guide rod 41 and the push plate 42 and moved downward a certain distance, but the push plate 42 has not yet contacted the magnetic rod sleeve 5. As the magnetic rod fixing plate 22 continues to move downward, the push plate 42 begins to contact the upper end of the magnetic rod sleeve 5. The magnetic rod fixing plate 22 continues to move downward, and the push plate 42 moves downward against the upper end of the magnetic rod sleeve 5. The magnetic rod sleeve 5 disengages from the fixing joint 3, and finally the magnetic rod fixing plate 22 rises to the high position.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
