Detailed description of the invention
Mechanism of the present invention and operation principle is described in detail below in conjunction with accompanying drawing.In order to better the present embodiment is described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.The corresponding same or analogous parts of same or analogous label.
Refer to shown in Fig. 1, the invention provides a kind of can the liquid-transfering device of Auto-mounting suction nozzle, comprise the pipetting device 1 for moving liquid and the several loading frames 2 for loading suction nozzle 3, this liquid-transfering device can automatically be controlled the suction nozzle 3 on stacked loading frame 2 to be installed on pipetting device 1 by motor and be removed by used loading frame 2, and does not affect the installation of the suction nozzle 3 on lower one deck loading frame 2.
Described pipetting device 1 comprises piston/cylinder 11 for moving liquid, be located at piston fixed head 12 above piston/cylinder 11, be fixedly connected on the several push bracket bars 13 on piston fixed head 12, the suction nozzle be located at below piston/cylinder 11 evades plate 14, be fixedly connected with several suction nozzles that described suction nozzle evades plate 14 evades bar 15 and is located at several that suction nozzle evades on plate 14 and move hack lever 16.The described hack lever 16 that moves is for mentioning when installing suction nozzle 3 loading the loading frame 2 of suction nozzle 3 and remove, and described push bracket bar 13 is for being unloaded moving the loading frame 2 that hack lever 16 mentions.Described suction nozzle is evaded corresponding described push bracket bar 13 on plate 14 and is provided with several the first through hole 403 passed for push bracket bar 13, described push bracket bar 13 can from this first through hole 403 through and relatively described suction nozzle evade plate 14 and move at vertical direction.
The described hack lever 16 that moves is provided with lug boss 161, and this lug boss 161 is one be sheathed on the annulus moved on hack lever 16, and this lug boss 161 is made up of rubber, elastic deformation can occur when extruding by external force, and described lug boss 161 is located at the bottom moving hack lever 16.Be provided with several suction nozzle below described piston/cylinder 11 and interrupt 17 for installing suction nozzle 3, entered in piston/cylinder 11 by suction nozzle 3 pipette samples liquid.Described suction nozzle is evaded plate 14 and 17 is removed for being interrupted from suction nozzle by suction nozzle 3.Described suction nozzle evades plate 14 and described suction nozzle, and to evade bar 15 relative fixing, and the motion that described suction nozzle evades plate 14 is evaded bar 15 by described suction nozzle and controlled.Described suction nozzle is evaded corresponding described suction nozzle on plate 14 and is interrupted and 17 be provided with several second through hole 407, thus the suction nozzle be installed on below piston/cylinder 11 is interrupted and 17 can be passed this second through hole 407, and suction nozzle 3 can not pass this second through hole 407, after suction nozzle 3 is installed, when the suction nozzle that moves down evades plate 14, this suction nozzle of contact is evaded plate 14 by the upper surface of suction nozzle 3, continues mobile suction nozzle and evades plate 14 can to promote suction nozzle 3 descending, thus is interrupted from suction nozzle by suction nozzle 3 and 17 to unload.
Described loading frame 2 comprises body 21, move hack lever 16 described in this body 21 correspondence to be provided with and severally to move frame aperture 26, described frame aperture 26 of moving is for through hole or blind hole, the external diameter of the described lug boss 161 moved on hack lever 16 is greater than the aperture that this moves frame aperture 26, hack lever 16 will be moved insert when moving in frame aperture 26, described lug boss 161 is squeezed to be contained in and moves in frame aperture 26, and lug boss 161 and the contact surface moved between frame aperture 26 of distortion produce frictional force, thus moves this loading frame 2 when hack lever 16 moves upward and be raised.The body 21 of described loading frame 2 is provided with several loading hole 23, for loading suction nozzle 3.
Refer to shown in Fig. 2, the operation principle of described liquid-transfering device is: first, several loading frame 2 is placed in below pipetting device 1, Electric Machine Control pipetting device 1 is descending, and suction nozzle is interrupted in 17 insertion suction nozzles 3, now, described move hack lever 16 insert move in frame aperture 26, described lug boss 161 distortion moved on hack lever 16 is contained in and moves in frame aperture 26, and due to lug boss 161 and the frictional force of moving between frame aperture 26, when being mentioned by pipetting device 1, described loading frame 2 is raised along with moving hack lever 16.When needs unload loading frame 2, described in Electric Machine Control, push bracket bar 13 moves downward, now suction nozzle is evaded bar 15 and is not moved, described suction nozzle is evaded plate 14 and is evaded bar 15 with suction nozzle and be fixedly connected with, the described hack lever 13 that moves is fixed at described suction nozzle and evades on plate 14, therefore now described suction nozzle evade plate 14 and described in move hack lever 16 and all maintain static, described suction nozzle is evaded plate 14 and is moved downward the power applying down to described loading frame 2, thus loading frame 2 moves down, frame aperture 26 is moved upward described in the relative loading frame 2 of the described lug boss 161 moved on hack lever 16 exits, the loading frame 2 losing frictional force drops because of Action of Gravity Field, namely automatically removing of loading frame 2 is completed.And in this process, it 17 is fixed that described suction nozzle evades that plate 14 interrupts relative to suction nozzle, the suction nozzle 3 therefore suction nozzle can not interrupted on 17 is hit down.Suction nozzle 3 had not only been installed on suction nozzle and has interrupted on 17 but also the loading frame 2 of empty frame is removed the installation avoiding the suction nozzle 3 affected on next loading frame 2 by whole process, therefore, multiple loading frame 2 that suction nozzle 3 is housed can be stacked together, thus decrease taking up room of suction nozzle 3, improve the operating efficiency of liquid-transfering device.
When suction nozzle 3 is hit down by needs, suction nozzle described in Electric Machine Control is evaded bar 15 and is moved downward, described suction nozzle is evaded plate 14 and is followed described suction nozzle and evade bar 15 and move downward, described suction nozzle is evaded plate 14 and is contacted suction nozzle 3 and push away under it, overcome the frictional force that suction nozzle is interrupted between 17 and suction nozzle 3, suction nozzle 3 drops because of Action of Gravity Field.
Liquid-transfering device of the present invention, multiple loading frame (suction nozzle on this stacked loading frame is superimposed dress suction nozzle) can be stacked on a dish position, the suction nozzle be pre-installed before using on whole loading frame is taken to facilitate automation, and multiple loading frame only takies a dish position, saves large quantity space; And after installing suction nozzle, empty loading frame can be removed automatically, do not affect the installation of lower one deck suction nozzle, achieve automation mechanized operation, and the suction nozzle on multiple loading frame entirety can carry out sterilizing simultaneously, decreases solid waste, improve sterilization effect, and then reduce production cost.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All any amendments done within the spirit and principles in the present invention, equivalent to replace and improvement etc., within the protection domain that all should be included in the claims in the present invention.
