Description
Die Erfindung betrifft ein Werkzeug zum Auftragen oder Aufstempeln eines Klebstoffes auf ein Substrat nach dem Oberbegriff des unabhängigen Anspruchs.The invention relates to a tool for applying or stamping an adhesive onto a substrate according to the preamble of the independent claim.
Beim Auftragen von Klebstoffen bzw. Klebstoffpunkten auf Substrate wie Platinen ist die sogenannte PIN-Transfertechnik oder „Nadel"-Transfertechnik mit Werkzeugen aus Metall oder Hartmetall bekannt. Dabei wird das Werkzeug in ein zuvor ausgerakeltes Klebstoffbett eingetaucht, so dass bei einem nachfolgenden Herausziehen des Werkzeugs eine bestimmte Menge an Klebstoff durch das Werkzeug aufgenommen wird, der anschließend durch Kontakt oder Annäherung insbesondere in Form eines Klebstoffpunktes auf ein Substrat aufgebracht wird.When applying adhesives or Adhesive dots on substrates such as circuit boards are the so-called PIN transfer technology or "needle" transfer technique known with tools made of metal or hard metal. It will Tool immersed in a previously scraped-out adhesive bed, see above that when the tool is subsequently pulled out, a certain one Amount of adhesive is absorbed by the tool, which is then by contact or approach is applied in particular in the form of an adhesive dot to a substrate.
Bei dieser Technik ist nachteilig, dass sich nach einiger Zeit bzw. einigen Wiederholungen dieses Übertragungszyklus in erheblichem Maße Klebstoff an dem Stempelwerkzeug anlagert, was zunehmend zum Applizieren unregelmäßiger Klebstoffmengen und unregelmäßiger Formen der aufgebrachten Klebstoffpunkte führt. Insofern ist es bisher erforderlich, das eingesetzte Werkzeug nach einigen Zyklen, beispielsweise 50 Zyklen, zu reinigen.This technique has the disadvantage that that after some time or a few repetitions of this transmission cycle to a considerable extent Adhesive attaches to the stamp tool, which is increasingly used for application irregular amounts of adhesive and irregular shapes of the applied adhesive points. So far it has been necessary the tool used after a few cycles, for example 50 Cycles to clean.
Das erfindungsgemäße Werkzeug hat gegenüber dem Stand der Technik den Vorteil, dass die aufgetragene bzw. auf das Substrat übertragene Klebstoffmenge auch bei kleinsten Punktgrößen deutlich reproduzierbar ist, was zu einem wesentlich stabileren und kostengünstigeren Übertragungsprozess führt und die Fertigungsqualität erheblich erhöht. Zudem erspart man sich durch Einsatz des erfindungsgemäßen Werkzeuges eine häufige Reinigung des Werkzeuges, was zu erheblichen Kosteneinsparungen und einer vereinfachten Fertigung führt.The tool according to the invention has compared to the Prior art has the advantage that the applied or on the Amount of adhesive transferred to substrate clear even with the smallest point sizes is reproducible, resulting in a much more stable and inexpensive transmission process leads and the manufacturing quality significantly increased. In addition, one saves by using the tool according to the invention a common one Tool cleaning, resulting in significant cost savings and leads to simplified production.
Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den in den Unteransprüchen genannten Maßnahmen.Advantageous further developments of Invention result from the measures mentioned in the subclaims.
So hat sich als besonders vorteilhaft herausgestellt, wenn die Antihaftbeschichtung aus einem Kunststoff mit niedriger Oberflächenspannung wie Teflon oder aus einem Hartstoff wie diamantartigem Kohlenstoff besteht. Besonders vorteilhaft ist das Aufbringen einer Teflonbeschichtung durch Besprühen eines Werkzeuges, das bevorzugt aus einem Metall, insbesondere einem Hartmetall besteht.So has proven to be particularly beneficial exposed if the non-stick coating is made of a plastic with low surface tension like Teflon or from a hard material like diamond-like carbon consists. Applying a Teflon coating is particularly advantageous by spraying a tool, preferably made of a metal, in particular a Tungsten carbide exists.
Der Transferbereich des Werkzeuges, der mit dem zu übertragenden Klebstoff in Kontakt kommt bzw. der den daran anhaftenden Klebstoff auf das Substrat durch Berühren mit diesem oder Annäherung an dieses überträgt, ist bevorzugt stabförmig, nadelförmig oder quaderförmig ausgebildet. Auf diese Weise bildet sich vorteilhaft auf dem Substrat ein mit Klebstoff versehener Bereich aus, der in Draufsicht zumindest näherungsweise punktförmig ist.The transfer area of the tool, the one with the one to be transferred Adhesive comes into contact or the adhesive adhering to it by touching the substrate with this or approximation transmits to this is preferably rod-shaped, needle-shaped or cuboid educated. This advantageously forms on the substrate an area provided with adhesive, at least in plan view approximately punctual is.
Vorteilhaft ist weiterhin, wenn eine Mehrzahl von Transferbereichen vorgesehen ist, mit denen bei einer Annäherung oder Berührung des Werkzeuges an das Substrat der Klebstoff auf einer Mehrzahl von Bereichen der Oberfläche des Substrates gleichzeitig transferierbar ist.It is also advantageous if one A plurality of transfer areas is provided with which at one approach or touch of the tool to the substrate the adhesive on a plurality of areas of the surface of the substrate is transferable at the same time.
