When nozzle separated with substrate, ZZ axle motor 541 must stop constantly driving driving arm 542 at this, and is mobile thereby driving arm 542 stops.But ZZ axle motor 541 can not stop driving arm accurately because of the delay of response time, thereby driving arm stops (S40) after further moving up a bit.
Position measurement sensor 570 is exported the change with respect to the position of sensor element 530 on perpendicular to the substrate surface direction of the position of jet element 550 as data signal, and does not produce the electronics equivalent noise.As a result, control module 70 is accurately identified nozzle from the make progress distance of process of substrate.
Control module 70 is proofreaied and correct the errors present of nozzle based on the value of measuring by position measurement sensor.That is, by the ZZ axle motor 541 driving driving arms 540 of control module 70 controls, so that jet element 550 moves down.
The use of ZZ axle motor 541 (such as linear motors) can stop driving arm at accurate point, and this makes operation of ignoring the errors present of proofreading and correct nozzle become possibility.
Control module 70 moves up the head unit 50 that comprises sensor element 530 and jet element 550, up to distribution height measuring transducer 520 indication first assigned references points " 0 " that are installed on the sensor element 530.Thereby, shown in Fig. 6 d, distribute 520 indications " 0 " of height measuring transducer, and nozzle 555 stops in certain height " A " (that is the specific range between nozzle 555 and the substrate 200).
As shown in Figure 7, even head unit 50 moves down up to distributing height measuring transducer 520 indication second assigned references points " a ", nozzle does not form with substrate yet and contacts.In this case, driving arm 542 moves down with jet element 550, forms with substrate up to nozzle to contact, and sensor element 530 keeps fixing simultaneously.
Shown in Fig. 6 b, ZZ axle motor 541 must form the moment that contacts at nozzle 555 and substrate and stop driving arm 550.But ZZ axle motor 541 is because the delay of response time can not make driving arm stop accurately, so driving arm 542 stops after further moving down a bit.
Position measurement sensor 570 is exported the change with respect to the position of sensor element 530 on perpendicular to the substrate surface direction of the position of jet element 550 as data signal, and does not produce the electronics equivalent noise.As a result, control module 70 is accurately identified the distance that nozzle moves to substrate downwards.
The value that control module 70 position-based measuring transducers are measured is proofreaied and correct the errors present of nozzle.That is, drive driving arms 540 by the ZZ axle motor 541 of control module 70 control, make jet element 550 move up (S600).
The use of ZZ axle motor 541 (such as linear motors) can make driving arm stop accurately, and this makes the step of ignoring the errors present of proofreading and correct nozzle become possibility.
Control module 70 moves up the head unit 50 that comprises sensor element 530 and jet element 550, up to distribution height measuring transducer 520 indication first assigned references points " 0 " that are installed on the sensor element 530.Thereby, shown in Fig. 6 d, distribute height sensor 520 indications " 0 ", and nozzle 555 stops in certain height " A " (that is the specific range between nozzle 555 and the substrate 200).
According to the present invention, the change with respect to the position of sensor element 530 on perpendicular to the substrate surface direction of the position of jet element 550 is output as data signal, and does not produce the electronics equivalent noise.This make the distance between gaging nozzle and substrate accurately and significantly reduce percentage of defects and nozzle is set and substrate between processing time of vertical range become possibility.
Under the situation that does not break away from spirit of the present invention and essential characteristic, the present invention can implement in a variety of forms, should be understood that also above-described embodiment is not limited to any details described above, unless otherwise indicated, but more should be interpreted as widely in the spirit and scope that claims limit, thereby all interior change and modifications of scope that fall into claim or its equivalent all should be included in the claims.
