Tube manipulation system
Technical field
The present invention relates to a kind of tube manipulation systems convenient for picking and placing individually.
Background technique
In strain experiment, sterile working is generally required, and there are many tested number, while may needed during the test
Individual test tubes are adjusted, the mode of operation that the prior art takes this, often in an aseptic environment, manually with hand pair
Single test tube is picked and placed, in this way, on the one hand enter gnotobasis for adjustment once in a while to operator and carry out complexity
Sterilization operate pole waste of resource, it is also extremely inconvenient, on the other hand due to pushing limited, also cause putting for test tube can not
Accomplish the maximization of space utilization.Also there is the mechanical device for picking and placing test tube in the prior art, but that generally takes full-automation
Operation, equipment supplier do not provide individual test tube fetching device generally, and the selling at exorbitant prices of a complete set of equipment, for middle-size and small-size enterprise
Industry is difficult to undertake really.It is various above to cause medium-sized and small enterprises' cost in the experiment of batch strain excessively high, and dangerous, by
This also causes medium-sized and small enterprises to be difficult to efficiently use having talent of high caliber.
If the Chinese invention patent of Patent No. CN201010573008.9 discloses a kind of test tube sample sorting device, benefit
The operation to single test tube is completed with hydraulic elevating platform, identification device and mechanical gripper, it is clear that the technical costs is higher, medium and small
Type enterprise necessarily causes cost excessively high in the case where undertaking such high expense, thus necessarily bears higher pressure in fund aspect
Power, to improve the operations risks of enterprise.

Specific embodiment
Be described further below technical solution of the present invention, but claimed range be not limited to it is described.
A kind of tube manipulation system convenient for picking and placing individually as shown in Figure 1, including clamping device, transmission device peace take
Device;The transmission device includes control cabinet 32, drive rod 33, clockwise and anticlockwise motor 31 and the time relay 34, the time relay
34 drive 32 input shaft of control cabinet, control cabinet 32 with 31 circuit connection of clockwise and anticlockwise motor, the output shaft connection of clockwise and anticlockwise motor 31
Output shaft is drive rod 33, and 33 distal end of drive rod has gear structure to nibble with the 16 lower section gear of driving lever in the clamping device
It closes;Driving lever 16 in the clamping device is upper, middle and lower three-stage structure, and upper section is lead screw, is covered on the screw of lead screw in hand wheel
In the horizontal gear of group 22, it is horizontally disposed with a gear on lower section bar, is engaged with 33 end gear of drive rod, between middle section and upper section
By socket bearing connection, connected between middle section and lower section by counter gear group 14;Described put down takes device to be set to clamping dress
Right above setting.
The clamping device includes that the clamping device includes columned test tube platform 1, the block-like movable block 11 of circular arc, circle
The block-like fixed block 12 of arc, the driving lever 16 for being connected to 1 bottom of test tube platform, bending are rod-shaped by lever 13;The test tube platform 1
The sliding slot of one circle of circle is provided on upper surface, sliding slot depth is less than the thickness of test tube platform 1, and 11 quantity of movable block is two, Gu
Determining 12 quantity of block is one, movable block 11 and fixed block 12 is horizontally movable inserts in sliding slot vertically, the sliding slot bottom surface
There is through slot;11 bottom of movable block is connected with by lever 13, and 16 top of driving lever is connected to 1 bottom of test tube platform, and two passive
The other end of bar 13 is connected to the middle section for being vertically arranged in driving lever 16 and lower section;It is described that set is had by 13 vertical component of lever
Barrel structure makes to be moved up and down by 13 top of lever without influencing rotation or movement by lever in the horizontal direction.
It is described that flat to take device include holding ring 41, movable block 42, strut 43, beam rail 45;The holding ring 41 is angle
Arc semi-ring less than 150 °, quantity are two, and two 41 levels of holding ring are oppositely arranged;The movable block 42 is arranged at two
Among 41 one side end of holding ring, and connected with the proximal end of two holding rings 41;The strut 43 is vertically arranged, and movable block 42 can
Mobile is fixed on 43 bottom of strut, and the moveable direction of movable block 42 is radial perpendicular to strut 43;On the holding ring 41
It is rotating wheel with one end similar in movable block 42, the two sides contacted on movable block 42 with holding ring 41 are fixed toothing, rotation
Wheel and fixed tooth engagement;It is aduncate structure at the top of the strut 43, has pulley 44 to be placed in beam rail 45 in warp architecture
On, translate strut 43 can along 45 direction of beam rail.
It is engaged there are also a vertical gear with horizontal gear in the hand wheel group 22, and there is an operating stick 21 to pass through vertical tooth
Wheel is vertically arranged with driving lever 16.
In use, movable block 42 is directed at test tube to be taken, rotation operating stick 21 makes 16 upper section of driving lever because of the work of hand wheel group
It moves and moves up, so that test tube platform 1 be made to be raised above independently of other test tubes, then slide strut 43 to test tube position, make
Test tube pushes movable block 42 close to strut 43, so that holding ring 41 is clamped by the engaging structure of rotating wheel and fixed tooth,
At this time clockwise and anticlockwise motor 31 is opened by the circuit control time relay 34 within a certain period of time, clockwise and anticlockwise motor 31 is made to pass through control
Case 32 processed rotates drive rod 33 corresponding with test tube to be taken, to pass through driving lever 16, by lever 13, the biography of counter gear group 14
Dynamic structure draws close two movable blocks 11 from both sides to fixed block 12, and then proceeding to translation strut 43 can will test tube be taken
Clamping completes the non-manual operations for taking pipe individually to predetermined position.
In above-mentioned setting, the setting of the time relay 34 essentially consists in the runing time of control clockwise and anticlockwise motor 31, makes to live
Motion block 11 stops being moved at the position for drawing close fixed block 12 just, or movable block 11 be moved to holding test tubes far from solid
Determine to stop at 12 suitable position of block.Obvious, the relative movement of movable block 21 is then easy for using positive and negative asynchronous machine 31.Together
When, since in actual use, a positive and negative asynchronous machine 31 may need to operate many drive rods 33, therefore take control cabinet 32
Setting, selection operation is carried out to the drive rod 33 that operates of needs.
In order to increase test tube bottom forced area, it is to recessed circle that part is enclosed in sliding slot in 1 upper surface of test tube platform
Arcuation.
For the same purpose, further, the opposite 43 distal end side of strut of the movable block 42 is the arc of horizontal direction
Face.
The counter gear group 14 is also auxiliarily fixed by horizontally disposed fixed link 15, and fixed link 15 passes through counter gear
The bearing of 14 middle gears of group center;The counter gear group 14 is upper and lower counter-rotational structure.Thus it mechanically realizes
Two 21 relative motions of movable block, and will not because of intermediate transmission gear it is mobile and lead to the generation of abnormal conditions.
The quantity of the rotating wheel is at least one on each holding ring 41;The width of the fixed tooth, which is greater than or equal to, to be turned
The width of driving wheel.Therefore ensure that the linkage effect between holding ring 41 and movable block 42.
