Description
Technical field
The utility model relates to micropipette instrument field, relates in particular to a kind of multichannel automatic pipettor of real-time detection suction nozzle.
Background technology
Biomation work station can be realized high flux imbibition, move liquid and liquid feeding, improved widely the preparation efficiency of sample, as a core component---the Multi-channel liquid transfer device on biomation work station, it need to change suction nozzle frequently, in the preparation process of sample, if some suction nozzles do not load and put in place or come off in the course of the work, all can destroy the preparation process of whole sample.
Multi-channel liquid transfer device generally adopts air displacement formula piston structure to realize imbibition and liquid feeding process, Multi-channel liquid transfer device generally needs the passage of a plurality of piston body structures, the restriction that is subject to processing and assembles, be difficult to guarantee that each piston body can be assembled to same level, will inevitably have influence on like this each passage suction nozzle and load rear sealing, how to design and can reduce matching requirements, and can improve the difficult point that each passage imbibition precision is also needs solution.
Utility model content
Whether utility model object: the utility model aims to provide a kind of multichannel automatic pipettor of real-time detection suction nozzle, can detect in real time suction nozzle and come off, and adopt the independently design of piston body structure passage can greatly reduce the requirement of assembling.
Technical scheme: a kind of multichannel automatic pipettor of real-time detection suction nozzle, comprise liquid-transfering device, be arranged on the suction nozzle of liquid-transfering device lower end and the fixing framework of liquid-transfering device, it is characterized in that, framework bottom surface offers through hole, on liquid-transfering device, be arranged with the contact block that can slide up and down, contact block outer wall is provided with the projection of extending to through hole edge, and the contact block of projection downside is with liquid-transfering device through through hole and to downward-extension, and the lower end of contact block contacts with suction nozzle; Also comprise position detecting device, position detecting device is connected with contact block.
Position detecting device comprises the battery lead plate being fixed in framework and is located at the electrode contact of end, contact block upper end, the through hole that battery lead plate is provided with a plurality of sensing electrodes and passes for liquid-transfering device; When contact block slides up and down, the sensing electrode on described electrode contact electric conduction pole plate.
Battery lead plate connects by winding displacement the electrode that framework end face is installed.Electrode is the electrode of golden finger type.The electrode of golden finger type, for coordinating with biomation work station, provides the status signal of suction nozzle to biomation work station.
At the sheathed top, outside of liquid-transfering device spring, the upper surface of top spring contacts with the lower surface of the gripper shoe that install position detecting device top, and the lower surface of top spring contacts with the upper surface of contact block.When suction nozzle is in place, contact block upward sliding in suction nozzle holder, top spring compressive deformation, and because the frictional force between suction nozzle and liquid-transfering device lower end is greater than the restoring force of top spring, suction nozzle can not come off; If but suction nozzle does not load and puts in place, the restoring force of top spring makes contact block down sliding, get back on liquid-transfering device slidably extreme lower position.
