[0030] [First Embodiment] like Figure 1-7 The image shown is a pipette module provided in the first embodiment of this utility model, as follows: Figure 1 As shown, the device includes a base 100 and a nut seat 200 disposed on one side of the base 100 and capable of sliding relative to the base 100. A first bearing seat 300 is fixed to the end of the base 100 near the motor, and a second bearing seat 400 is fixed to the end of the base 100 away from the motor. A motor mounting seat 500 is fixed to the outside of the first bearing seat 300. The motor is fixed to the outside of the first bearing seat 300 through the motor mounting seat 500, and its output end is fixedly connected to the lead screw inside the base 100. The motor outputs power to drive the lead screw to rotate synchronously, and then drives the nut seat to slide relative to the base on one side of the base, thereby causing the external load fixedly connected to the nut seat to slide relative to the base, thus replacing the manual liquid handling process and enabling real-time and accurate liquid sample processing.

[0031] like Figure 1-3 As shown, the base 100 in this embodiment is typically made of aluminum alloy, which is lightweight and high-strength. The base 100 is used to support its internal lead screw and to install bearing seats and motor mounting seats on both sides. Bearing seat mounting holes 101 are provided at both ends of the base 100. The first bearing seat 300 and the second bearing seat 400 are fixedly installed at both ends of the base 100 through the bearing seat mounting holes 101. A guide rail mounting hole 102 is provided on the front side of the base 100. The guide rail 600 is fixedly installed on the front side of the base 100 through the guide rail mounting hole 102. A cover plate mounting hole 103 is provided on the top of the base 100. The cover plate 900 is fixedly installed on the top of the base 100 through the cover plate mounting hole 103. A lead screw through hole 104 is provided inside the base 100. The lead screw 800 is rotatably inserted into the lead screw through hole 104.

[0032] like Figure 4As shown, the nut seat 200 in this embodiment includes a nut base plate 201, a slider seat 202 and a nut seat 203 fixed as one piece, which are used to slide with the guide rail while constraining the nut. The slider seat 202 and nut seat 203 are respectively fixed to the side of the nut base plate 201 facing the base 100. The nut seat 203 has a nut mounting hole 2031 inside, and the nut 700 is fixedly installed inside the nut mounting hole 2031 to engage with the lead screw thread and drive the nut seat 200 to move axially relative to the lead screw. The nut seat 203 has lead screw through holes 2032 on both sides, and the lead screw 800 passes through the lead screw through holes 2032 and the nut 700 and is threadedly connected to the nut 700. The nut base plate 201 has a slider connection hole 2011 and a load connection hole 2012 on both sides. One side of the slider seat 202 is slidably engaged with the guide rail 600, and the other side of the slider seat 202 is fixedly connected to the nut base plate 201 through the slider connection hole 2011. The external load is fixedly connected to the nut base plate 201 through the load connection hole 2012, so that the external load is driven to slide synchronously relative to the base 100 through the nut seat 200 to realize the pipetting operation.

[0033] The structural base material of pipette modules is generally aluminum alloy, taking advantage of its lightweight and high strength properties. However, as an exception, the thread nut 200 in this embodiment is a key structure for transmitting axial force in this pipette module structure. In this specific implementation, in order to obtain better structural rigidity, the thread nut 200 adopts an integrated design, and its material is Q235A with a blackened surface treatment to obtain better rust and corrosion resistance, thereby extending the overall service life of the pipette module structure.

[0034] It is worth noting that in this embodiment, the basic shape of the nut seat 200, as well as the nut mounting hole 2031 and the lead screw through hole 2032, are first obtained by wire cutting, and then the slider connection hole 2011 and the load connection hole 2012 are machined by a machining center.

[0035] like Figure 5 As shown, in this embodiment, the first bearing housing 300 is used to install the first bearing B1 and a motor (not shown). It includes a first bearing housing base plate 301 disposed near the base 100. The first bearing housing base plate 301 has a first bearing housing first side plate 302 and a first bearing housing second side plate 303 fixed at both ends on the side away from the base 100, respectively. The first bearing housing first side plate 302 and the first bearing housing second side plate 303 have motor mounting holes 3021 inside. The motor mounting seat 500 is fixedly connected to the first bearing housing first side plate 302 and the first bearing housing second side plate 303 through the motor mounting holes 3021. The first bearing housing base plate 301 has a first bearing mounting hole 3011 inside. The first bearing is installed inside the first bearing mounting hole 3011.

[0036] It is worth noting that the height of the first side plate 302 of the first bearing housing is lower than the height of the second side plate 303 of the first bearing housing, which can provide space for the conveyor belt and effectively avoid interference when the conveyor belt transmits motor power.

[0037] like Figure 6 As shown, in this embodiment, the second bearing housing 400 is used to mount the second bearing B2. It includes a second bearing housing base plate 401 disposed near the base 100. The second bearing housing base plate 401 has a base mounting hole 4011 and a second bearing mounting hole 4012 respectively. The second bearing housing base plate 401 is fixedly connected to the base 100 through the base mounting hole 4011. The second bearing is mounted inside the second bearing housing base plate 401 through the second bearing mounting hole 4012.

[0038] In this embodiment, both the first bearing B1 and the second bearing B2 are deep groove ball bearings, which have a simple structure, are easy to use, and can be used to bear both radial and axial loads at the same time.

[0039] like Figure 7 As shown, the motor mounting base 500 in this embodiment includes a motor connecting part 501 and a motor mounting part 502 that are fixedly connected. The motor connecting part 501 is disposed near the base 100 for fixed connection with the first bearing seat, and the motor mounting part 502 is disposed away from the base 100 for mounting the motor. The motor connecting part 501 has a motor connecting hole 5011 inside that is fixedly connected with the first bearing seat 300, and the motor mounting part 502 has a motor mounting hole 5021 inside that is used to mount the motor.

[0040] In this embodiment, the motor mounting hole 5021 is located in the center of the motor mounting part 502. Tension adjustment holes 5022 are provided at the four corners of the motor mounting part 502. The tension adjustment holes 5022 are made of slotted holes, so that the tension of the conveyor belt can be adjusted through the slotted holes. By moving the position of the motor, the center distance between the driving pulley and the driven pulley can be adjusted, thereby realizing the tension adjustment of the synchronous belt.

[0041] As one preferred transmission method, the output end of the motor is connected to the lead screw via a belt drive assembly. The belt drive assembly includes a driven pulley 801 fixedly disposed at the end of the lead screw near the motor and a driving pulley fixedly connected to the output end of the motor. The two ends of the conveyor belt are respectively wrapped around the outer periphery of the driving pulley and the driven pulley 801.

[0042] The pipette module provided in this embodiment can be used individually or in multiples simultaneously. The motor outputs power to drive the nut to slide relative to the base on one side, thereby causing the external load fixedly connected to the nut to slide relative to the base, thus replacing the manual pipetting process and achieving real-time and accurate liquid sample processing.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
