The operation of the dispense tip device of an embodiment that is equipped with piston connection/separator is described now.
The cylinder component 520 that inside is inserted with piston 550 is installed on the bottom of support housing 430 by means of linkage unit 440.At this moment, the convex connecting elements 552 of piston 550 is positioned matrix connecting elements 671 belows of axle 670.
Electric current is applied to electromagnet.The magnetic field that is produced by electromagnetism forces the convex connecting elements 552 of piston 550 to move into the matrix connecting elements 671 of axle 670, keeps convex connecting elements 552 and matrix connecting elements 671 closely to contact with connected mode thus.
The operation of first rotation motor 620 is with rotating shaft 670 and with the piston 550 of the tight engagement shaft 670 of connected mode.First rotation motor, 620 rotary-pistons 550 are so that the groove 553 in the piston 550 is in the face of the flow channel 522 in the cylinder component 520.
Linear drive unit 700 moves up rotary drive unit 600 to set a distance, moves the piston 550 that is connected to axle 670 thus.
Moving upward of piston 510 produces pressure differential between the inside of piston hole 521 and liquid crystal supply unit 530.This can make liquid crystal 530 flow into piston holes 512 from the liquid crystal supply unit.
First rotation motor, 620 rotary-pistons 550 are so that the groove 513 in the piston 550 is in the face of the flow pass 523 in the cylinder component 520.
Whenever linear drive unit 700 moves down rotary drive unit 600 and piston 550 to set a distance, a liquid crystal droplet drips towards substrate by the flow pass 523 in the cylinder component 520 from nozzle unit 540.Rotary drive unit 600 and piston 510 continue to move down, up to till the liquid crystal droplet of substrate drippage specified rate.
When the piston 550 in cylinder component 520 and the insertion cylinder component 520 need be replaced with new cylinder component and new piston, no longer apply electric current to electromagnet 680.As a result, electromagnet does not produce magnetic field.This falls down from axle 670 owing to its deadweight with regard to allowing piston 550.The nut 442 of linkage unit 440 from bolt 441 spiral Panasonics, is removed with the cylinder component 520 that inside is inserted with piston 550.The new cylinder component 520 that inside is inserted with new piston 550 is fixed to the lower member 433 of support housing 430 by means of linkage unit 440.According to the mode identical with aforesaid way, the convex connecting elements 552 of piston 550 keeps closely contacting with connected mode with the matrix connecting elements 671 of axle 670.
Utilization is installed in the electromagnet on the axle 670 that constitutes rotary drive unit 600, can be convenient and easily the convex connecting elements 552 of piston 550 is connected or separates with the matrix connecting elements 671 of axle 670.
In addition, use electromagnet but not actuator and the axle that is connected to actuator, the feasible size that can reduce rotary drive unit.Because electromagnet is connected to axle 670 in its mode that is positioned at first rotation motor, 620 belows, so base member 610 diminishes, the size of electromagnet is littler than actuator 640.This just makes the size of rotary drive unit 600 reduce.
In addition, the size of rotary drive unit reduces and then has reduced dispense tip device size and weight.This just allows the dispense tip device that first guide unit 310 is produced the moment value of less degree and first guide unit 310 is under the less eccentric load.As a result, the second driver element D2 of mobile dispense tip device is under the less heavy load.
Because the present invention can implement with the some forms that do not break away from purport of the present invention or intrinsic propesties, therefore also should understand, above-mentioned embodiment is not limited to aforementioned any details, unless otherwise, otherwise should be in the spirit and scope of the invention that claims limit interpreted in its broadest sense, ie, and therefore fall in the border of claim scope and the boundary or all changes in the equivalency range of these borders and boundary and modification are intended to claims and contain.
