Technical field
This utility model relates to a kind of multichannel Qu Ye mechanism, specifically, is that the parallel liquid multi-point that takes of a kind of multichannel seals piston mechanism, belongs to bio-screening technologies field, liquid working station。
Background technology
Current in liquid handling work station, liquid assimilating and discharging mechanism generally use air pump to realize, and the physical size yet with gas circuit is inconsistent, and the parallel accuracy of imbibition is difficult to keep。Meanwhile, adopt use on multichannel different air pump often bulky, control complexity, cannot realize in the big figure passages such as such as 96,384 control。If using single air pump to control multiple passages, due to the air resistance difference on each passage, operation repetitive also cannot be realized。
Therefore, prior art have also been developed the piston mechanism of a kind of similar syringe motion, is realized imbibition and the tapping function of liquid by piston rod up and down motion in cavity。Each passage uses a piston, thus making each passage realize independent liquid manipulation。
In current piston mechanism, use the result of same syringe all fours, a piston up-down with sealing ring in outer sleeve, it is achieved the absorption of liquid and discharge。Both fitnesss are required height by this structure, accurately to adjust perpendicularity and the centrad of piston and sleeve during assembling, and otherwise sealing cannot ensure。This so the processing request of each parts is high, passing rate of processing is low；Assembling extremely complex in big figure channel design, yield rate is low。
Utility model content
The parallel liquid multi-point that takes of multichannel that the purpose of this utility model is in that to provide that a kind of simple in construction, processing are convenient, assembling is simple, can realize favorable sealing property seals piston mechanism, it is achieved such as the multichannel high flux liquid handling of big figure such as 96,384。
This utility model takes techniques below scheme:
The parallel liquid multi-point that takes of a kind of multichannel seals piston mechanism, suction nozzle installing plate 9, piston rod 4, piston cap 2, cover plate 1, pressing plate 6, piston installing plate 5, suction nozzle 10；Described piston plate installing plate 5 is fixed on suction nozzle installing plate 9 top, and each piston rod 4 upper end is connected by piston cap 2 is fixing with cover plate 1, and described cover plate 1 is connected with driving mechanism；Described pressing plate 6 is fixed with suction nozzle installing plate 9 upper end, and piston rod 4 is led；The position that each piston cavity of lower end of described suction nozzle installing plate 9 is corresponding is fixedly installed suction nozzle 10。
Further, it is provided with an O RunddichtringO 3 between described piston installing plate 5 and piston rod 4。
Further, described suction nozzle installing plate 9 top and piston rod 4 corresponding position are provided with back-up ring 7, and described back-up ring 7 top is fixedly installed the 2nd O RunddichtringO 8。
Further, suction nozzle installing plate 9 has one group parallel 96 passage, and piston rod 4 has a group 96 of correspondence。
The beneficial effects of the utility model are in that:
1) simple in construction, processing facility, assembling is simple；
2) the parallel liquid multi-point that takes of the multichannel of favorable sealing property can be realized and seal piston mechanism, it is achieved such as the multichannel high flux liquid handling of big figure such as 96,384；
3) quantitative liquid suction precision is high；
4) operational reliability is higher。
5) the utility model proposes a kind of piston mechanism using multi-point to seal on each passage, change existing single-point seal form, can be used for the manipulation of any number of Multi-channel liquid, be especially suitable for imbibition and the tapping of the liquid of big figure passage。
6) processing request is low, easy to assembly, it is ensured that sealing, it may be achieved the depth of parallelism of more than the 0.1%C.V. in 96 passages。
Accompanying drawing explanation
Fig. 1 is that the parallel liquid multi-point that takes of this utility model multichannel seals the generalized section of piston mechanism。
In figure, 1 cover plate, 2 piston caps, 3 the oneth O RunddichtringOs, 4 piston rods, 5 piston rod installing plates, 6 pressing plates, 7 back-up rings, 8 the 2nd O RunddichtringOs, 9 suction nozzle installing plates, 10 suction nozzles。
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further illustrated。
Described multi-point seals piston mechanism as it is shown in figure 1, include the parts such as piston rod 4, piston cap 2, back-up ring 7, cover plate 1, pressing plate 6, piston installing plate 5, suction nozzle installing plate 9 and first, second O RunddichtringO 3,8。
Piston rod 4 and first, second sealing O 3,8 closely cooperate, and the pressing plate 6 that the first O 3 compresses with it again is fully contacted, and piston rod 4 moves back and forth in suction nozzle installing plate 9, and mechanism seals is functional。
This utility model mechanism also includes back-up ring 7, the 2nd O RunddichtringO 8 on shield ring sleeve, is placed between pressing plate 6 and suction nozzle installing plate 9。Mechanism back-up ring 7 is prevented from piston rod 4 motor process the 2nd O RunddichtringO 8 and deforms and produce gap and affect mechanism's seal。
This utility model mechanism multi-point seals, and is embodied in and combines at back-up ring 7 and the second O 8, forms ground floor and seals structure, and back-up ring 7 and the second O 8 extrude between pressing plate 6 and suction nozzle installing plate 9, good airproof performance after the 2nd O RunddichtringO 8 pressurized。First O 3 and piston rod 4 form the second layer and seal structure, and this structure is fixed with piston installing plate 5 through cover plate 1, and extruding the oneth O RunddichtringO 3 forms good sealing。This utility model mechanism makes full use of the material behavior of O, i.e. elastic deformation, and the gap between piston rod 4 and piston installing plate 5 is blocked, and forms good sealing。
The utility model proposes a kind of piston mechanism using multi-point to seal on each passage, change existing single-point seal form, can be used for the manipulation of any number of Multi-channel liquid, be especially suitable for imbibition and the tapping of the liquid of big figure passage。Processing request is low, easy to assembly, it is ensured that sealing, it may be achieved the depth of parallelism of more than the 0.1%C.V. in 96 passages。
Additionally, this utility model mechanism is when keeping sealing, and the processing request of workpiece is low, when assembling without accurately adjusting centrad between piston and piston installing plate and perpendicularity as existing assembling mode, particularly in big figure channel design, yields is high。Compared with prior art, multichannel multi-point of the present utility model seals piston mechanism does not have the frame for movement of complexity, and assembling is simple, reduces processing and the technical difficulty of assembling, it is provided that good sealing, it is ensured that the collimation between multichannel。
