Description
Die vorliegende Erfindung betrifft eine Vorrichtung gemäß dem Oberbegriff des Hauptanspruchs und ein Verfahren gemäß dem Oberbegriff des Nebenanspruchs.The The present invention relates to a device according to the preamble of the main claim and a method according to the preamble of the independent claim.
In
der
Nachteilig bei dem vorstehend beschriebenen Verfahren sind die durch einen relativ hohen Aufwand verursachten hohen Kosten.adversely in the method described above are by a relatively high costs caused high costs.
Es ist damit Aufgabe der vorliegenden Erfindung eine Vorrichtung und ein Verfahren zum Verschweißen von Kunststoffen zur Herstellung von Werkstücken, und ebenso entsprechend gefertigte Werkstücke, dahin gehend zu verbessern, dass diese einfach und kostengünstig bereit gestellt sind.It is the object of the present invention, a device and a method of welding of plastics for the production of workpieces, and also accordingly manufactured workpieces, To improve it, make it easy and inexpensive are placed.
Die Aufgabe wird durch eine Vorrichtung gemäß dem Hauptanspruch, durch ein Verfahren gemäß einem Nebenanspruch sowie durch ein Werkstück gemäß einem weiteren Nebenanspruch gelöst. Weitere vorteilhafte Ausgestaltungen finden sich in den Unteransprüchen.The The object is achieved by a device according to the main claim a method according to a Nebenanspruch and by a workpiece according to another additional claim solved. Further advantageous embodiments can be found in the subclaims.
Für das Durchlichtschweißen von Kunststoffen wird nun anstelle eines Lasers mindestens eine Lampe, insbesondere eine Infrarot-(IR-) Lampe, eingesetzt. Zum Verschweißen von Werkstückteilen, insbesondere von Kunststoffteilen, mittels Durchlichtschweißen, wird mindestens eine Lampe, insbesondere Infrarotlampe, zur Emission eines Strahlungsspektrums zur Bereitstellung von thermischer Leistung in einer Fügezone zwischen einem ersten Werkstückteil und einem mit dem ersten Werkstückteil zu verschweißenden zweiten Werkstückteil vorgesehen. Die Lampen zeichnen sich dadurch aus, dass sie im Vergleich zu einem Laser hohe Lichtausbeuten zu sehr geringen Kosten generieren.For transmitted light welding of Plastics will now use at least one lamp instead of a laser, in particular an infrared (IR) lamp used. For welding of Workpiece parts, in particular of plastic parts, by means of transmitted light welding, at least one lamp, in particular infrared lamp, for emission of a radiation spectrum for providing thermal power in a joining zone between a first workpiece part and one with the first workpiece part to be welded second workpiece part intended. The lamps are characterized by being compared to generate a laser high luminous efficacy at very low cost.
Lampen – die insbesondere durch elektrisches Aufheizen eines Metallabschnitts Strahlung emittieren – eigenen sich zum Durchlichtschweißen nicht in jedem Fall, da eine Lampe ein breites Spektrum an Licht aussenden kann. Im Fall der Verwendung von Lampen mit den in Verbindung mit dem Stand der Technik beschriebenen pigmentierten Kunststoffen, kann ein hoher Lichtanteil im sichtbaren Bereich ausreichen um auch die Oberfläche bzw. ein erstes Werkstückteil anzuschmelzen. Dies ist unerwünscht. Der für das menschliche Auge sichtbare Bereich sei mit ca. 380 nm bis ca. 780 nm angenommen. Die Grenzen sind aufgrund individueller Abweichungen von Mensch zu Mensch fließend. Die Lampe soll damit möglichst außerhalb des sichtbaren Bereichs emittieren. Entsprechend sollte das Strahlungsspektrum einer Lampe entsprechend vorteilhaft ausgewählt werden. Gemäß einer vorteilhaften Ausgestaltung sendet die Lampe, insbesondere IR-Lampe, ein Spektrum elektromagnetischer Strahlung aus, und zwar lediglich im Infrarotbereich, im Wesentlichen im Bereich zwischen ca. 800 nm und 1500 nm.Lamps - the particular by emitting electric radiation of a metal section emitting radiation - own not for transmitted light welding in any case, as a lamp emits a wide range of light can. In the case of using lamps in conjunction with the prior art described pigmented plastics, a high proportion of light in the visible range can be sufficient, too the surface or a first workpiece part to melt. This is undesirable. The for the human eye visible range is about 380 nm to about 780 nm assumed. The limits are due to individual deviations flowing from person to person. The lamp should be as possible outside of the visible region. Accordingly, the radiation spectrum should a lamp can be selected correspondingly advantageous. According to one advantageous embodiment sends the lamp, in particular IR lamp, a spectrum of electromagnetic radiation, and only in the infrared, essentially in the range between about 800 nm and 1500 nm.
Gemäß einer vorteilhaften Ausgestaltung können Lampen, insbesondere IR-Lampen, mit einer Lichtleistung bis zu 200 W verwendet werden. Dies ist zum Kunststoffschweißen mehr als ausreichend.According to one advantageous embodiment can Lamps, in particular IR lamps, with a light output of up to 200 W be used. This is more for plastic welding as sufficient.
Sendet die Lampe, insbesondere IR-Lampe, ein breites Spektrum an Licht bzw. elektromagnetischer Strahlung aus, und zwar vom für den Menschen sichtbaren Bereich bis weit in den Infrarotbereich, im Wesentlichen im Bereich zwischen 500 nm und 1500 nm, ist es vorteilhaft zwischen Lampe und dem ersten Werkstückteil mindestens ein Filter zur Ausfilterung störender Spektralbereiche zu positionieren. Störende Spektralbereiche können je nach Kunststoffzusammensetzung der Werkstückteile beispielsweise im für das menschliche Auge sichtbaren Bereich liegen. Werden nun vor die Lampe geeignete Filter angebracht, so sinkt zwar die Lichtleistung, aber diese ist immer noch ausreichend. Diese Anordnung ist aufgrund des eingeschränkten Spektralbereichs für das Durchlichtschweißen mit entsprechend pigmentierten Werkstoffen uneingeschränkt verwendbar.Sends the lamp, in particular IR lamp, a wide range of light or electromagnetic radiation, from the human visible range far into the Infrarotbe rich, substantially in the range between 500 nm and 1500 nm, it is advantageous to position at least one filter between the lamp and the first workpiece part for filtering out interfering spectral regions. Depending on the plastic composition of the workpiece parts, disruptive spectral ranges can be in the range visible to the human eye, for example. If suitable filters are placed in front of the lamp, the light output will decrease, but this is still sufficient. This arrangement is due to the limited spectral range for the transmitted light welding with appropriately pigmented materials fully usable.
Gemäß einer vorteilhaften Ausgestaltung ist das Filter zur Absorption und/oder Reflexion des von der Lampe emittierten Spektrums im für das menschliche Auge sichtbaren Bereich und zur Transmission des von der Infrarotlampe emittierten Spektrums im Infrarotbereich ausgebildet.According to one advantageous embodiment, the filter for absorption and / or Reflection of the emitted spectrum of the lamp in the human Eye visible area and to the transmission of the infrared lamp emitted spectrum formed in the infrared range.
Gemäß einer vorteilhaften Ausgestaltung ist das Filter zur Ausfilterung von sonst ohne diese Ausfilterung durch das erste Werkstückteil absorbierter und/oder reflektierter Strahlung ausgebildet, wobei die das Filter passierende Strahlung das erste Werkstückteil transmittiert und von dem zweiten Werkstückteil im Bereich der Fügezone absorbiert wird.According to one advantageous embodiment, the filter for filtering out otherwise absorbed without this filtering by the first workpiece part and / or reflected radiation formed, wherein the filter passing Radiation the first workpiece part transmitted and absorbed by the second workpiece part in the region of the joining zone becomes.
Gemäß einer vorteilhaften Ausgestaltung ist das Filter hinsichtlich Absorption, Transmission und Reflexion des Strahlungsspektrums an die optischen Eigenschaften des ersten Werkstückteils angepasst bzw. angeglichen. Es erfolgt eine entsprechende Angleichung des Filters an die jeweils verwendeten pigmentierten Kunststoffe. Eine Anpassung kann ebenso lediglich teilweise, das heißt lediglich für Spektralteilbereiche vorgenommen werden. Die von dem Filter ausgefilterte Strahlung braucht nicht mehr von dem pigmentierten Kunststoff des ersten Werkstückteils aufgenommen werden. Grundsätzlich gibt es keine Einschränkung hinsichtlich der verwendeten pigmentierten Kunststoffe.According to one advantageous embodiment, the filter is in terms of absorption, Transmission and reflection of the radiation spectrum to the optical properties of the first workpiece part adapted or adjusted. There is a corresponding approximation of the filter to the particular pigmented plastics used. An adjustment can also only partially, that is only for spectral subareas be made. The radiation filtered out by the filter needs no longer of the pigmented plastic of the first workpiece part be recorded. in principle there is no restriction with regard to the pigmented plastics used.
Gemäß einer vorteilhaften Ausgestaltung weist das Filter ein die Absorption, Reflexion und die Transmission bereitstellendes Filtermedium auf. Das heißt die Filterwirkung wird zum größten Teil durch das Filtermedium erzeugt. Dieses kann fest, flüssig oder gasförmig sein.According to one advantageous embodiment, the filter has the absorption, Reflection and the transmission providing filter medium. This means the filter effect is for the most part generated by the filter medium. This can be solid, liquid or gaseous be.
Gemäß einer vorteilhaften Ausgestaltung ist das Filtermedium in einer Glasform, insbesondere Quarzglasform, eingeschlossen. Damit wird das Filtermedium im Raum positioniert.According to one advantageous embodiment, the filter medium is in a glass mold, in particular quartz glass form, enclosed. This will become the filter medium positioned in the room.
Gemäß einer vorteilhaften Ausgestaltung ist das Filtermedium zwischen zwei in einem geringen Abstand zueinander angeordneten, gegeneinander abgedichteten Glasplatten, insbesondere Quarzglasplatten, eingeschlossen. Damit ist besonders einfach ein robustes Filter zu realisieren, das den auftretenden großen Wärmebelastungen standhält.According to one advantageous embodiment, the filter medium between two in a small distance apart, sealed against each other Glass plates, in particular quartz glass plates, enclosed. In order to is particularly easy to implement a robust filter that the occurring large heat stress withstand.
Gemäß einer vorteilhaften Ausgestaltung strömt das Filtermedium, das ein geeignetes Absorptionsverhalten aufweist. Durch das Filtermedium wird beispielsweise eine Absorption im sichtbaren Bereich und eine Transparenz im Infrarotbereich erzeugt. Durch das Strömen wird nicht nur eine Zersetzung des flüssigen Filtermediums vermieden, sondern es wird zudem das Glas gekühlt. Das heißt, das Filtermedium strömt zur Abführung von thermischer Leistung und zur Vermeidung eines Zersetzens des Filtermediums. Dieses kann flüssig und/oder gasförmig sein.According to one advantageous embodiment flows the filter medium which has a suitable absorption behavior. By the filter medium, for example, an absorption in the visible Area and a transparency in the infrared generated. By the Stream not only is a decomposition of the liquid filter medium avoided, but it is also the glass cooled. That is, that Filter medium flows to the exhaustion of thermal power and to avoid decomposing the Filter medium. This can be liquid and / or gaseous.
Gemäß einer vorteilhaften Ausgestaltung zirkuliert das Filtermedium zur Begrenzung der nötigen Filtermediumsmenge. Das heißt, das erwärmte Filtermedium strömt zu kühleren Bereichen im Kreislauf, gibt die Wärme ab und strömt zum als Filter wirkenden Bereich zurück, wobei ein neuer Zyklus beginnt. Der als Filter wirkende Bereich liegt im Strahlungsbereich der Lampe. Das Filtermedium kann flüssig und/oder gasförmig sein.According to one advantageous embodiment circulates the filter medium for limiting the required filter medium amount. This means, the heated Filter medium flows to cooler Areas in the circulation, gives off the heat and flows as Filter acting area back, whereby a new cycle begins. The area acting as a filter lies in the radiation range of the lamp. The filter medium can be liquid and / or gaseous be.
Gemäß einer vorteilhaften Ausgestaltung ist das Filtermedium eine Flüssigkeit, insbesondere Wasser.According to one Advantageous embodiment, the filter medium is a liquid, especially water.
Gemäß einer vorteilhaften Ausgestaltung ist das Filtermedium schwarz oder farbig. Das Filtermedium kann dabei die gleiche Farbe oder Pigmentierung entsprechend dem ersten Werkstück teil aufweisen. Die optische Angleichung kann damit über die Farbe erfolgen.According to one advantageous embodiment, the filter medium is black or colored. The filter medium can be the same color or pigmentation Part according to the first workpiece exhibit. The optical alignment can thus be done via the color.
Gemäß einer vorteilhaften Ausgestaltung ist eine Fokussieroptik zur Fokussierung der von der Lampe emittierten Strahlung in die Fügezone geschaffen.According to one advantageous embodiment is a focusing optics for focusing created the radiation emitted by the lamp in the joining zone.
Die vorstehend genannten Vorrichtungen eignen sich besonders vorteilhaft für Durchlichtschweißverfahren zum Verschweissen von aus Kunststoff, insbesondere aus einem thermoplastischen Kunststoff, bestehenden Werkstückteilen.The The aforementioned devices are particularly advantageous for transmitted light welding for welding of plastic, in particular of a thermoplastic Plastic, existing workpiece parts.
Gemäß einer vorteilhaften Ausgestaltung ist ein Werkstück aus Kunststoff, insbesondere aus einem thermoplastischen Kunststoff, bestehenden Werkstückteilen, derart erzeugt, dass es ein, insbesondere entlang eines Weges zu einer Fügezone, für Infrarotlicht transparentes erstes Werkstückteil und ein, insbesondere im Bereich der Fügezone, Infrarotlicht absorbierendes zweites Werkstückteil aufweist. Grundsätzlich sind vergleichbare Anpassungen an andere Spektralbereich entsprechend der Pigmentierung der Kunststoffe möglich.According to an advantageous embodiment, a workpiece made of plastic, in particular of a thermoplastic plastic, existing workpiece parts, produced such that it, in particular along a path to a joining zone, transparent to infrared light first workpiece part and, in particular in the region of the joining zone, infrared light absorbing having second workpiece part.
