Robot system for assembling HELICOIL thread inserts

The robot system automatically fully assembles Helicoil thread inserts in die-casting components. Two handling robots supply the thread-forming station, assemble the Helicoil thread inserts and place the finished parts on pallets which are then placed in the transport rack. The solution includes a series of specially developed robotic stations, including the assembly station for the Heli-Coil thread inserts. An inline test of all essential processing steps ensures the highest level of process reliability.

In the handling cell, one robot loads and unloads the thread-forming station where the interior threads for holding the Helicoil inserts are formed in the die-casting components. The workpieces are placed on a carrier tray that is transported to the assembly cell. There, the second robot takes over and feeds the tray into the Helicoil thread insert assembly station. With the help of two NC assembly spindles, the robots place two Helicoil inserts on the spindles that are then rotated into the interior threads. At another station, the tangs that were needed for the previous assembly step are broken off and vacuumed up. The first robot then automatically places the finished parts on the transport tray.

For almost 25 years, we have planned, developed and constructed robot-supported production systems as well as processing, assembly and handling solutions for our customers. Our more than 1,000 projects successfully implemented – from the robot cell to the completely interconnected production system – are a testament to our process expertise and experience across all industries.

We focus on custom-made solutions that include process analysis and design, software development and machine construction. We deliver them turnkey ready so they easily integrate into your production environment. We also offer standardized modular systems that can be easily and flexibly modified and are scalable to meet your production requirements.

We have compiled several sample projects so you can better understand how we operate.
