On the basis of such scheme, the utility model also provides further prioritization scheme:
Referring to Fig. 3, in this prioritization scheme, have additional a pillar 106, this pillar 106 is used for support level vertical direction actuating arm 102, thereby so that the structure of whole device is more firm, then guarantee that can carry out stably horizontal direction under the in the horizontal direction driving of actuating arm 101 of horizontal vertical direction actuating arm 102 moves the positioning accuracy of the whole device of Effective Raise.
As described in Figure 4, the free end of horizontal vertical linking arm 102a is fixedly connected on pillar 106 and the horizontal vertical direction actuating arm 102, it mainly comprises a cylinder 106a, rotating shaft 106b and steady pin 106c, the length of cylinder 106a matches with the height of the upper horizontal vertical linking arm 102a of device, the free end of one end and horizontal vertical linking arm 102a is fixedly connected, and in the vertical direction is vertical with horizontal vertical linking arm 102a, the other end of cylinder 106a offers a rotary axis groove 106a1, and this rotary axis groove 106a1 matches with rotating shaft 106b.Rotating shaft 106b is placed among the rotary axis groove 106a1 by steady pin 106c is rotating.Simultaneously be provided with corresponding shaft block ring 106d at steady pin 106c, so that steady pin 106c is fixed.
The pillar 106 that forms thus is when cooperating horizontal vertical direction actuating arm 102 to use, when moving horizontally under the in the horizontal direction driving of actuating arm 101 of horizontal vertical direction actuating arm 102, pillar 106 is by the rolling of the rotating shaft 106b of bottom, can realize that pillar 106 moves horizontally with horizontal vertical direction actuating arm 102, thereby can guarantee the stability of horizontal vertical direction actuating arm 102 whole moving process, then the accuracy that positions of the whole device of Effective Raise.
For guaranteeing mobile accuracy, the drive motors in the utility model can adopt corresponding servomotor simultaneously.
It is mobile simultaneously to control respectively three directions based on the multi-shaft interlocked liquid dispensing apparatus 100 of such scheme formation by three control modules, does not interfere with each other, and can greatly improve the mobile Efficiency and accuracy of sampling probe.It is as follows that it carries out the operating process that three directions carry out shift action simultaneously:
Horizontal direction actuating arm 101 is used for realizing sampling probe 104 movement in the horizontal direction, the i.e. movement of X-direction in the whole device; Horizontal vertical direction actuating arm 102 is used for realizing that sampling probe 104 is in the movement of horizontal vertical direction, the i.e. movement of Y direction; Vertical direction actuating arm 103 is used for realizing the movement of sampling probe 104 in the vertical directions, the i.e. movement of Z-direction.
When need move to a certain particular location with sampling probe 104, upper main frame calculates according to sampling probe 104, horizontal direction actuating arm 101, horizontal vertical direction actuating arm 102 and vertical direction actuating arm 103 relative position relation with destination locations, obtain respectively that horizontal direction actuating arm 101 should drive mobile displacement, horizontal vertical direction actuating arm 102 should drive mobile displacement and vertical direction actuating arm 103 should drive mobile displacement, form simultaneously corresponding control signal.The displacement that upper main frame moves control signal and three actuating arm respective drive is sent to control module 101c, 102c and the 103c on each actuating arm simultaneously.
The first control module 101c on the horizontal direction actuating arm 101 is after receiving control signal, to drive immediately the first drive motors 101b work, to drive horizontal vertical direction actuating arm 102 integral body are carried out X-direction (being horizontal direction) along the first guide rail movement by the first drive motors 101b, then drive vertical direction actuating arm 103 along the movement of X-direction (being horizontal direction) by horizontal vertical direction actuating arm 102, moreover drive sampling probe 104 along the movement of X-direction (being horizontal direction) by vertical direction actuating arm 103.
Horizontal vertical direction actuating arm 102 is simultaneously mobile along X-direction (being horizontal direction), the second control module 102c on it is after receiving control signal, also will drive immediately the second drive motors 102b work, drive second guide rail of vertical direction actuating arm on 103 along its by the second drive motors 102b and carry out the movement (in the horizontal direction perpendicular to horizontal direction actuating arm 101) of Y direction (being the horizontal vertical direction), so that vertical direction actuating arm 103 carries out the movement of X-direction and Y direction (being the horizontal vertical direction) both direction simultaneously, carry out simultaneously the movement of X-direction and Y direction both direction and drive sampling probe 104 by vertical direction actuating arm 103.
When vertical direction actuating arm 103 moves when carrying out X-direction and Y direction both direction, the 3rd control module 103c of vertical direction actuating arm 103 is after receiving control signal, also will drive immediately the 3rd drive motors 103b work, drive sampling probe 104 by the 3rd drive motors 103b and carry out movement on the Z-direction (being vertical direction) along the 3rd guide rail, so that sampling probe 104 carries out X-direction simultaneously, the movement of Y direction and Z-direction, and the mobile slotted eye 102a1 that passes on the horizontal vertical linking arm 102a in Z-direction reaches corresponding position.
After finishing corresponding sampling, three actuating arms will be finished according to such scheme while execution action the playback of sampling probe.
Hence one can see that, and the utility model utilizes three actuating arm dislocation spatially to operate simultaneously, realizes that sampling probe moves in X, Y, three directions of Z axis, greatly improves the efficient of liquid batch operation.
