Definitions
- the invention relates to a laser welding tool with a first and a second tool part for fixing a first welding article to a second welding article.
- the first welding article and the second welding article are at least partially disposed between the two tool parts.
- a laser welding process for automatic transmission oil filter is known.
- two arranged between an upper and a lower tool filter plastic shells are connected by laser welding for producing an automatic transmission oil filter.
- a filter medium is clamped by means of a clamping rib.
- the superimposed filter half-shells are welded by their common edge by laser light.
- One of the filter half-shells consists of laser light-permeable plastic and the other filter half-shell of laser light-impermeable plastic.
- the laser beam is guided through the laser light-permeable filter half-shell along the contact point with the other filter half-shell. He hits the laser light-impermeable filter half shell.
- the object is achieved according to a first aspect of the invention by a laser welding tool with a first and a second tool part.
- the first and second tool parts are provided for fixing a first welding article to a second welding article.
- the second tool part comprises for pressing the second welding article against the first welding article at least two independently movable towards the first tool part parts.
- the two independently displaceable sub-elements allow the two tool parts to press each other in segments.
- an increased pressure can always be built up there, where a laser has just produced a weld that is still hot and flexible. This can be particularly effective in helping the cooled and hard weld to be particularly smooth and precise.
- the pressure can be changed continuously or incrementally.
- the sub-elements are automatically displaced. This allows a particularly precise shifting of the sub-elements, for example by an electronic control device.
- each sub-element is coupled to at least one actuator for automatically moving the corresponding sub-element.
- the actuators are preferably adjusted pneumatically, hydraulically, electrically or by spring force. This allows the automatic shifting of the sub-elements in a simple manner.
- the second tool part for pressing the second welding article against the first welding article comprises three or more displaceable towards the first tool part sub-elements.
- This makes it possible to apply the pressure even more precisely along the fresh weld seams to several different segments of the two welding articles and can thus contribute to making the weld seam particularly uniform, in particular if several lasers are used for welding.
- the invention is characterized according to a second aspect of the invention by an arrangement for welding two welding articles with at least one laser, the laser welding tool and the control device.
- the control device is coupled to the laser and the laser welding tool and configured to enable the shifting of the partial elements of the laser welding tool as a function of a position of the laser.
- the arrangement comprises two or more lasers, each of which is permanently assigned to one or more sub-elements. This can contribute to the particularly precise and rapid production of the welds.
- the invention is characterized according to a third aspect of the invention by a method for operating the device.
- the two welding articles are placed on each other in the first or second tool part.
- the first welding article may be fixed to the first tool part and the second welding article may be fixed to the second tool part.
- the sub-elements of the second tool part are then moved toward the first tool part or the first tool part is moved towards the second tool part, that the two welding articles are welded together.
- the first segments of the two welding articles are welded to the laser.
- the first segments are arranged in the direction of movement of the first sub-element between the first sub-element and the first tool part.
- the first sub-element is moved towards the first tool part and so the two welding articles are pressed against each other at their first segments.
- Second segments of the two welding articles are also welded to the laser, wherein the second segments are arranged in the direction of movement of the second part element between the second part element and the first tool part.
- the second sub-element is moved towards the first tool part and so the two welding articles are pressed against each other at their second segments. This contributes to the particularly precise and uniform formation of the welds, since the segments are always pressed against each other when the welds are still hot and flexible and still a relative movement of the two welds to each other is possible.
- the same contact pressure is generated evenly at approximately the same temperatures of the welds.
- the contact pressure can be increased stepwise or continuously and / or varied during pressing.
- more than two sub-elements are provided and the sub-elements are always moved towards the first tool part when the corresponding segments of the two welding articles were welded. This can particularly effectively contribute to producing the uniform welds, especially if the weldments are large and a division into several segments makes sense and / or if several lasers are provided.
- each subelement can be assigned a laser.
- two or more sub-elements each have their own laser assigned. Especially with very large welding articles, this can contribute to the particularly uniform and precise formation of the weld.
