This link 510 has exhaust port 515 in the inboard.This exhaust port 515 passes the cloudy attachment hole 511 in bottom, cylindrical body 512 and positive attachment portion 514.
This cylindrical body 512 has inclined-plane 516.This inclined-plane 516 is formed some part of a side of excision cylindrical body 512.When in the cloudy attachment hole 331 that link 510 is inserted on the hollow shaft 330, these inclined-plane 512 contacts are from the outstanding projection 332 of hollow shaft 330.
This bar 520 has given length and external diameter.This bar 520 has groove 521 on a side.
An end that does not have the bar 520 of groove 521 is inserted in the cloudy attachment hole 511 in bottom on the link 510.
Utilize Bond to be connected on the link 510 at an end of bar 520.Just, the cloudy attachment hole 511 in bottom is coated with Bond, and the end with bar 520 is inserted in the cloudy attachment hole 511 in bottom then.When the end with bar 520 is inserted in the cloudy attachment hole 511 in the bottom that is coated with Bond, produce bubble.At this moment, this bubble is run out of by the exhaust port on the link 510 515.
Because stupalith has advantage in moulding, and not with liquid crystal generation chemical reaction, so this bar 520 can be made with pottery.
Because anti-scratch of stainless steel and wearing and tearing are so link 510 can be made with stainless steel.
The method that is used to make according to piston of the present invention is described now.
Fig. 9 is the flow chart that explanation is used to make the step of piston.Figure 10 is the view that explanation is used to make the method for this piston.
As shown in Fig. 9 and 10, be manufactured on this bar 520 that has groove 521 on the side.The two ends of this bar 520 all are flat.By excise some part of bar 520 along its length from an end to the set point this end and the other end, form groove 521.This bar 520 can be made with pottery.
The prototype M that preparation is made by non-ferrous metal with given shape.This prototype M is made up of cylindrical body 512, truncated cone shape body 514 ', the cloudy attachment hole 511 in bottom and exhaust port 515.This cylindrical body 512 has given external diameter and assigned altitute.Cloudy attachment hole 511 passes cylindrical body 512 and truncated cone shape body 514 ' to exhaust port 515 from the bottom.
Prepare the prototype M of size greater than link 510.
This prototype M can make with stainless steel.
The cloudy attachment hole 511 in bottom on this prototype M is coated with Bond.Then, one of them bar 520 is inserted in the cloudy attachment hole 511 in bottom, so that bar 520 is connected on the prototype M.Swingle 520 and prototype the time, this cylindrical body 512 and truncated cone shape body 516 on the prototype M are machined into given size together.The connection opening 513 that will be inserted into wherein from axle 350 outstanding attachment portions 351 is formed on the truncated cone shape body 514 '.This connection opening 513 comprises along the direction perpendicular to the center line of truncated cone shape body 514 ' passes its attachment hole, and is connected the seam between the upside of this hole and truncated cone shape body 514 '.This connection opening 513 can utilize wire cutting technology to form.
Operation of the present invention is described now.
Bolt is inserted into piston 500 is inserted in the groove 611 on wherein the cylinder component 600, and attachment portion 351 that simultaneously will this axle 350 is inserted in the connection opening 513 on the piston 500.By swivel bolt 251, cylinder component 600 closely is fastened on the base plate 240.
Adopt this piston and the structure that is provided with the cylinder of this piston, the liquid crystal of specified rate once can be injected this and enter the space, discharge with given number of times as a drop then, discharge till on each panel area up to the liquid crystal of the specified rate that will equate with the benchmark amount of liquid crystal.
Be inserted into wherein cylinder component 600 in order to change piston, rotary drive unit 300 moves down, and actuator 340 moves down axle 350 then, thereby moves down piston 500.This makes the positive attachment portion 514 of piston 500 withdraw from from the cloudy attachment hole 331 on the hollow shaft 330.In order to unload cylinder component 600, nut 252 rotations are to move down it.
This cylinder component 600 separates with bolt 251, and separate with the attachment portion 351 of axle 350 the positive attachment portion 514 of piston 500 simultaneously.
It is as follows to be used to the method made according to piston of the present invention.Prepare bar 520 and prototype M.Prototype M is machined into link 510.This bar 520 is connected on the prototype M.Then, M is machined into given size with this prototype, simultaneously swingle 520 and prototype M.If connection opening 513 is formed on the prototype M after the machining, then produce link 510.This makes the identical possibility that becomes of center line of the link 510 in center line that will be inserted into the bar 520 in the piston hole 621 and the attachment portion 351 that will be inserted into axle 350.Just, make that the center line that will be inserted into the bar 520 in the piston hole 621 is identical with the center line of link 510.
When the end with bar 520 is inserted in the cloudy attachment hole 511 in the bottom that is coated with Bond, between bar 520 and prototype M, produce bubble.At this moment, bubble is run out of by the exhaust port on the link 510 515.This prevents to form bubble between the surface of contact of the surface of contact of bar 520 and prototype M.Bubble is present in the adhesive force that has weakened between the surface of contact of the surface of contact of bar 520 and prototype M between bar 520 and the prototype M.
The cylinder 620 that is inserted in the cylinder seat 610 can given in the set a distance mobile in cylinder seat 610 inside.This makes by mobile piston 500 and cylinder 620, can not make under the center line of piston 500 situation identical with the center line of axle 350, makes the center line of piston 500 and spools 350 the identical possibility that becomes of center line by mobile piston 500 and cylinder 620.
So, piston can along with in cylinder, slide up and down and rotate around identical center line.
When utilization had cylinder component according to piston of the present invention, by around the center line rotary-piston, to open inlet opening, sliding piston on the center line was cried and the liquid crystal of specified rate is once injected the space that enters of cylinder then.And, by with given number of times around the center line rotary-piston, closing inlet opening, and open the outflow opening, along center line piston is glided to set a distance then, discharge liquid crystal droplet with given number of times by nozzle.Just, the each downslide of piston given set a distance, just discharges a dropping liquid crystalline substance by nozzle.
Because the present invention can realize with several forms under the situation that does not break away from its spirit or essential characteristic, so also should be understood that, unless stated otherwise, the foregoing description is not limited by any details of aforementioned description, and should in its spirit and scope defined in the appended claims, broadly explain, therefore fall into the boundary of claim or the interior all changes and the modification of equivalent of this boundary and all comprise by claims.
