As preferably, the anterior torus structure of described correlation induction apparatus and the hollow at rear portion
Cylindrical structure is one-body molded.
As preferably, in described correlation induction apparatus, it is provided with emission sensor amplifier.
Using the syringe needle mechanism of calibration automatically to calibrate syringe needle flexibility and the method for height, it includes
Following steps:
(1) two correlation induction apparatus symmetry is mounted opposite, and two correlation induction apparatuss divide
Do not link together with motion control card；
(2) syringe needle is fixed around kinematic axis at four emission sensors of correlation induction apparatus
Post moves according to circular interpolation movement locus, makes syringe needle can accurately encounter correlation induction apparatus and send out
The light gone out 4 times；
(3) after every time light four times encountered by syringe needle, by the probe capturing function of motion control card
Write down Current mechanical coordinate immediately, 4 points (X, Y) try to achieve two linear equations, then by directly
Line equation tries to achieve intersecting point coordinate, and the intersecting point coordinate tried to achieve is i.e. the datum mark of syringe needle；
(4), after writing down datum mark, when changing syringe needle use syringe needle recalibration next time, intersection point is sat
Target change is exactly the bending change of syringe needle；
(5) after trying to achieve intersecting point coordinate, the top of axis of motion to intersecting point coordinate, kinematic axis
Drive syringe needle slowly toward declining, encounter moment of emission sensor when syringe needle and write down current Z axis
Mechanical coordinate, the Z axis coordinate of for the first time calibration i.e. datum mark, when needle exchange head next time
Again the intersecting point coordinate tried to achieve the when of the pin of school compares with reference coordinate, i.e. may know that syringe needle is high
The variable quantity of degree is how many.
The beneficial effects of the present invention is:
The present invention uses mechanical coordinate calibration syringe needle flexibility and height change, two correlation senses
Device symmetry is answered to be mounted opposite；Syringe needle passes around kinematic axis at four correlations of correlation induction apparatus
Sensor is fixed and moved according to circular interpolation movement locus in post (can also be other motion rail
Mark, can correctly encounter the light that correlation induction apparatus sends just may be used for 4 times as long as syringe needle can be met
With), make syringe needle accurately to encounter light that correlation induction apparatus sends 4 times；Light encountered by syringe needle
After line four times, the probe capturing function of motion control card write down Current mechanical coordinate immediately, by
4 points (X, Y) try to achieve two linear equations, then are tried to achieve intersecting point coordinate by linear equation, try to achieve
Intersecting point coordinate be i.e. the datum mark of syringe needle；After writing down datum mark, change syringe needle and use under syringe needle
During secondary recalibration, the change of intersecting point coordinate is exactly the bending change of syringe needle；After trying to achieve intersecting point coordinate,
Axis of motion is to the top of intersecting point coordinate, and kinematic axis drives syringe needle slowly toward declining, and works as syringe needle
The moment encountering emission sensor writes down the mechanical coordinate of current Z axis, for the first time the Z of calibration
Axial coordinate i.e. datum mark, the intersection point tried to achieve when the nose heave new school pin of needle exchange next time when is sat
Mark compares with reference coordinate, i.e. may know that the variable quantity of needle height is how many.
