Description
Technical field
The present invention relates to jet printing appts, more particularly, to a kind of variable diameters jet printing appts.
Background technology
Current electronic industry development is more and more rapider, and flexible electronic (Gates B D.Flexible
electronics.Science,2009,323(5921):1566-1567) a kind of new electronic technology is represent, it is special with its
Flexibility and ductility and large area, the manufacturing process of low cost, be obtained in fields such as biology, medical science widely develop and
Using.Therefore, what flexible electronic manufacturing technology also developed is very rapid, and flexible electronic manufacturing technology the most frequently used at present mainly has
(Zhang Naibai, Guo Qiuquan, Yang Jun the figure punch flexible electronic devices such as direct writing technology, inkjet technology and electrofluid printing technique
Progress [J] Chinese sciences of part:Physics mechanics astronomy, 2016 (4)).Electrofluid Printing techniques are mainly that solution exists
Sprayed after surface tension is overcome in the presence of high voltage electric field from nozzle, spraying, fiber or drop are produced, due to equipment, technique
It is simple to be widely used in the manufacture of flexible electronic, mainly including electrostatic spinning, electrostatic spray and droplet spray printing.And mesh
What preceding electrofluid Printing techniques used greatly is nozzle, uses extrusion type liquid supply mode so that feed flow hysteresis quality is more
Seriously, this just make its can not by obtain continuous quick variable diameters it is micro-/receive fiber or drop.
When axle rotates in non-newtonian fluid, fluid can be acted on by shearing force, and the flow unit being sheared has bullet
Property restoring force, produce bag axle rod-climbing effect (K.Weissenberg, A Continuum Theory of Rheological
Phenomena.Nature.159(1947)310-311.)。
The content of the invention
It is an object of the invention to for can not be obtained during electrofluid spray printing continuous quick variable diameters it is micro-/receive fiber or
A kind of the problem of drop, there is provided variable diameters jet printing appts.
The present invention be provided with rotary shaft, reservoir, dispensing needle head, shaft coupling, servomotor, high voltage power supply, motion platform and
Collecting board；The rotary shaft and dispensing needle head form shower nozzle；The reservoir storage spray printing liquid coordinates with dispensing needle head；It is described to watch
Motor shaft is taken with rotary shaft by shaft coupling to couple；The servomotor drives rotary shaft to be rotated in spray printing liquid, due to pole-climbing
The effect of effect, spray printing liquid are transported to dispensing needle head needle point；It is deposited in the spray printing liquid of needle point in the presence of high voltage electric field
On collecting board, formed on collecting board it is micro-/receive fiber or drop, the motion platform drives collecting board motion, in high-tension electricity
In the presence of spray printing it is micro-/receive fiber or droplet deposition on collecting board, pin is controlled by the rotating speed for changing servomotor
Sharp spray printing liquid measure, and then realize variable diameters spray printing.
Under the rotating speed of a certain determination, fluid-flow rate be it is certain, spray printing it is micro-/receive the diameter of fiber or drop
And certain；Rotating speed is increased or is decreased to an other speed in a short period of time, now, spray printing liquid flowing velocity
It can be accordingly increased within the time of pole section or be decreased to another value, this just causes the spray printing liquid measure of needle point to undergo mutation, and enters
And realize spray printing it is micro-/diameter of fiber or drop received changes in a short time, realize the effect of variable diameters spray printing.
The present invention proposes a kind of variable diameters jet printing method, and non-newtonian fluid is produced showing for bag axle pole-climbing by the shearing force of axle
As a kind of mode of movement of solution；Rotating speed is bigger, and fluid-flow rate is bigger, and fluid-flow rate turns with rotating speed
It is very fast to become response, by quickly changing rotating speed in jet printing process to realize the effect of variable diameters spray printing.
The present invention is based on rod-climbing effect, is increased using liquid flow velocity with rotating speed and increased, and responds the characteristics of fast,
Realize the fast transition of feed flow by quickly changing rotating speed during electrofluid spray printing, so obtain different-diameter it is micro-/receive fiber
Or drop, realize variable diameters spray printing.
