Specifically, the cable rolling-up mechanism 50 further includes having rotating electric machine 54 and being horizontally set on leading on casing outer wall Rail 55, the guide rail 55 are equipped with feedblock 56, and the feedblock 56 is equipped with loop 57, and the feedblock 56 is equipped with the The output end of one connecting rod 58, the rotating electric machine 54 is equipped with the second connecting rod 59 hinged with first connecting rod 58；Rotating electric machine 54 Work can make second connecting rod 59 rotate, and so that second connecting rod 59 is able to drive first connecting rod 58 and rotate, make the first company Bar 58 is able to drive feedblock 56 and moves, and feedblock 56 is enable to drive loop 57 and the power transmission cable across guide collar It moves, when power transmission cable being enable uniformly to be wrapped in cable reel 51, power transmission cable is avoided to be wound on cable reel 51 When overlap phenomenon.

The working principle of the invention: power transmission cable is wrapped on cable reel 51 by worker, and will be by power transmission cable One end pass through loop 57 and charging pipette tips 20 are attached, the enough pipette tips 20 that will charge of user's manual energy are inserted into charging gun slot In 11, the pile body 10 that enables to charge charges to charging pipette tips 20, and by charging, pipette tips fixed mechanism 30 be can be realized pair The end clamping operation for the pipette tips 20 that charge improve charging pipette tips 20 will not there is a phenomenon where loosening during placement The safety for the pipette tips 20 that charge, the work of driving motor 37 can drive transmission gear 313 to rotate, transmission gear 313 made to exist It can be engaged with rack gear 36 during rotation, rack gear 36 is enable to be moved in the horizontal direction, enable 36 band of rack gear It moves one of support frame as described above 35 to move, so that support frame 35 is able to drive the shifting material movement of block 34, enable to move material block 34 It drives a rotating bar 311 mobile, so that rotating bar 311 is able to drive drive rod 39 and rotate, be able to drive drive rod 39 Another rotating bar 311 rotates, so that two shifting material blocks 34 be enable to relatively move, two support frames 35 is enable to distinguish It drives two limit plates 32 to move, so that two limit plates 32 is carried out limit operation to the end of charging pipette tips 20, lead to Overcharge pipette tips protection mechanism 40, which can be realized, carries out compression operation to the top of charging pipette tips 20, keeps charging pipette tips 20 steady Admittedly being pressed on bearing seat 41, charging pipette tips 20 are made not detach bearing seat 41 under the effect of external force, and can be realized To the charging rain-proof of pipette tips 20 and dust-proof, it is thus also avoided that irrelevant personnel touches charging pipette tips 20, passes through lifting assembly 43 can be realized the lift work of protecting crust 414, and protecting crust 414 is enable to carry out protection and rain-proof dust-proof to charging pipette tips 20, The work of lifting motor 47 can drive driving gear 412 to rotate, and driving gear 412 is made to be able to drive the hair of driven gear 413 Raw rotation, makes driven gear 413 be able to drive rotation axis 48 and rotates, rotation axis 48 is made to be able to drive two first bevel gears 49 rotate, and so that first bevel gear 49 is able to drive the second bevel gear 411 engaged and rotate, make two driving wires Bar 45 can drive two sliding shoes 44 mobile respectively, so that sliding shoe 44 is able to drive the movement of mounting base 46, enable protecting crust 414 Enough liftings are to suitable height, convenient for protecting charging pipette tips 20, while protecting crust 414 be able to drive voltage regulation part 60 into Row movement enables lower platen 61 to carry out compression operation to the top of charging pipette tips 20, can be right by cable rolling-up mechanism 50 Power transmission cable is wound, and is avoided power transmission cable there is a phenomenon where winding and wearing, is improved the service life of power transmission cable, receive The volume work of motor 52 can make cable reel 51 rotate, and the winding for enabling cable reel 51 to complete to power transmission cable is made Industry, the work of rotating electric machine 54 can make second connecting rod 59 rotate, and second connecting rod 59 is made to be able to drive the generation of first connecting rod 58 Rotation, makes first connecting rod 58 be able to drive feedblock 56 and moves, and feedblock 56 is enable to drive loop 57 and across leading Moved to the power transmission cable of circle, when power transmission cable being enable uniformly to be wrapped in cable reel 51, avoid power transmission cable around Overlap phenomenon when on cable reel 51.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution The range of scheme.
