Abstract:
The invention relates to a dispensing process particularly for a sealing/adhesive product (14) which comprises at least one step of pumping the sealing/adhesive product to allow a step of distribution thereof onto at least one part to be sealed, such as for example a motor-vehicle mechanical component (5), an intermediate step of deaeration of the sealing/adhesive product, so as to optimize its distribution on the part to be sealed, is provided between the pumping step and the distribution step. The apparatus for dispensing the sealing/adhesive product (14) comprises elements (2) for feeding the sealing/adhesive product to elements (4) for distributing it onto at least one part (5) to be sealed and sealing/adhesive product deaeration means (3) which cooperate with the pumping and distribution elements for the uniform deposition of the sealant/adhesive on the part.
Abstract:
Das Mischungsverhältnis einer auf eine Bahn (1), die zwischen einer Auftragswalze (6) und einer Gegendruckwalze (4) einer Beschichtungsvorrichtung hindurchläuft, aufgebrachten, aus einer flüssigen Zwei-Komponenten-Beschichtungsmasse bestehenden Beschichtung (9) wird dadurch geregelt, daß die beiden Komponenten in einem dem gewünschten Mischungsverhältnis entsprechenden Mengenverhältnis in eine Mischungeinrichtung eingeleitet werden, aus der dann die Beschichtungsmasse durch eine Leitung (10) der Beschichtungsvorrichtung zugeführt wird. Um das gewünschte Mischungsverhältnis über die gesamte Betriebsdauer beibehalten zu können, wird der Anteil der Komponenten an der Beschichtungsmasse in der Leitung mit einem Grenzwinkel-Refraktometer (15) gemessen. Der Ist-Wert wird mit einem Soll-Wert des Mischungsverhältnisses verglichen und bei der Messung einer Abweichung wird der der Mischeinrichtung zugeführte Mengenstrom der zuviel vorhandenen Komponente verringert und/oder derjenige der zuwenig vorhandenen Komponente wird erhöht.

본 발명은 각종 스마트 기기들에 탑재되는 플렉서블 패널의 제작 공정 중의 하나인 소위 디스펜서 공정에 관한 기술로서, 플렉서블 패널의 일면에 장착되는 인쇄회로기판 상의 칩이나 IC와 같은 복수의 정밀 부품에 대해 한꺼번에 레진 용책을 도포시키는 기술에 관한 것이다. 특히, 독립적인 동작제어가 가능한 복수 개의 액토출 부재를 구비함에 따라 서로 다른 레진도포 양이나 레진도포 두께에도 불구하고 피가공체에 대해 한꺼번에 서로 다른 양이나 두께의 레진 용액을 도포할 수 있도록 하는 기술에 관한 것이다. 본 발명에 따르면, 종래의 액토출 부재가 피가공체의 멀티 지점을 담당하기 위해 왕복이동하는 구성을 배제시킴에 따라 장치의 전체 사이즈를 줄일 수 있는 장점이 있다.
Abstract:
PROBLEM TO BE SOLVED: To provide a substrate processing apparatus and a substrate processing method which quickly form a liquid film covering an entire main surface of a substrate while inhibiting the increase of the cost thereby improving the quality of the substrate processing.SOLUTION: A substrate processing apparatus comprises: substrate holding rotation mechanisms 2, 3 holding and rotating a substrate W; a process liquid supply mechanism 4 having a process liquid nozzle 11 discharging a process liquid toward a main surface of the substrate W; a process liquid accumulation part 5 accumulating an amount of the process liquid which is sufficient to form a liquid film covering the entire main surface of the substrate W; a liquid film formation unit 6 which supplies the process liquid accumulated in the process liquid accumulation part 5 to the main surface of the substrate W at once thereby forming the liquid film covering the entire main surface of the substrate W; and a control unit 7. The control unit 7 allows the process liquid nozzle 11 to discharge the process liquid toward the main surface of the substrate W after the liquid film covering the entire main surface of the substrate W is formed.
