Our special-purpose machines can be used to perform roll hemming, glueing, tox clinching, caulking and many other joining procedures. The realisation of these form-fit and force-fit procedures enables automated, fail-safe assembly of components. The joining systems carry out tasks within defined cycle times, which can be flexibly integrated into an active production process.
Joining systems – concept examples
Using the following custom joining systems, we are able to reproduce all common procedures:
In the case of the roll hemming system for side doors, we have already planned in the eventual change of type – not just with a large selection of creasing tools in the tool station. There is also a simple option for correcting the folded components.
During the roll hemming procedure, two sheets that are sealed with an adhesive layer are joined together via form fit. One advantage of this joining procedure is that the sheets are not bent, but are rather rolled into one another using a hemming tool. This results in lower notch tensions, and the sheet surfaces remain undamaged.
Imagine if it only took eight seconds to position eight tox points on a component, measure these points, analyse and document the quality control with an embossing stamp and then automatically stack the components in transport containers: this is how quickly joining can be completed using the tox clinching procedure in a robotic production cell. The tox clinching procedure involves clinching, whereby the sheet metal parts are joined to one another by means of a pressing force.
The foam bead and glue bead application system uses robots for the precise spraying of single and dual-component plastics. After a component has been fixed in a clamping device, the plastic surface is activated by means of plasma flame treatment.
The glue or foam bead is then applied by robot, after which the joint is sealed. The entire process is visualised, and all of the data is recorded and logged in the quality control using a camera for traceability.
We have also developed automated solutions for underbody protection and the cavity preservation of body shells. For example, flatstream and airless coating systems are used for PVC plastics.
Ten different D-platform body types can “glide” through the system for the application of PVC joint seals and area seals, since the correction of the robotics coordinate systems is controlled by an image processing system with four cameras. The systems we build also include components for complete handling.
In a partially automated system for the crimping of plunge joints, the joint cage is fixed in the pivot pin using ball bearings, to prevent it from slipping out. The worker manually loads and unloads the unit – which uses camera technology to automatically check the completeness of the component and the correct alignment. The readjustment by the alignment station is also automated, just like in the crimp-joining process. The proper crimping of the plunge joint is checked once again at the end of the process, using camera technology.
Assembly systems join parts in perfect synchronisation, precisely and continuously. We are the specialists in special-purpose machines, achieving automated, failsafe assembly of fixtures by means of joining procedures such as screwing, riveting, pressing and welding. The assembly process is fully automated: supplying and detecting parts, verifying quality, positioning, tightening, mounting, testing, labelling and packaging. Small parts and sub-assemblies are stacked or put into interim storage.
