Inline Vision & Weld Quality Assurance System Combines Optical and Laser Technologies
Kistler and Nidec SYS have announced a new Inline Vision & Weld quality assurance system – a fully integrated solution for stamping technology. The system is the only one of its kind to combine the optical quality inspection of punching strips from Kistler with the precise servo-controlled cutting and laser welding technology from Nidec SYS. Inline Vision & Weld enables users to wind exclusively OK parts onto the punched part coil in a seamless strip.
Inline Vision & Weld (IVWS) finds and removes every ‘Not OK’ part in the production of punched parts. The new quality assurance system combines the KVC 621 optical inspection cell from Kistler with the high-precision Cutting Welding 2.0 system from Nidec SYS. The system examines the individual test parts for dimensional accuracy and relevant surface defects. If it finds such a defect, the system separates the corresponding NOK part and precisely welds the punching strip back together in the inline process in pitch. This ensures that only OK parts are on the coil, that downstream processes are guaranteed, and high-quality standards such as those of the automotive industry are met.
“At the beginning of our collaboration with Nidec SYS, we examined our customers’ needs for fully automated punching processes, fast and efficient quality assurance and, above all, optimal downstream processing steps in detail, and designed our solution to meet these requirements,” explains Dr. Oliver Schnerr, Head of Sales – Integrated Solutions at Kistler. “That’s why we combined optical quality inspection and laser welding technology in a fully integrated and automated system. Now, a detected bad part no longer causes idle time in the production process,” adds Werner Borth, CEO at Nidec SYS.

Minimizes Production Interruptions and Increases OEE
The optical part of the quality assurance system accommodates up to four integrated camera stations in its 1100-millimeter-wide housing and uses close-meshed PLC monitoring to reliably inspect every single part, even at cycle times of up to 2000 parts per minute. The cutting and laser welding technology is seamlessly combined with the optical quality inspection. The cutting tool works reliably thanks to its progressive die technology and cuts the punching strip within consistent parameters. Thanks to the integrated stand-alone welding technology and state-of-the-art welding techniques, the composite of the carrier strips is reproducible.
The system is also easy to install. Suitable power and pneumatic connections and an interface with the punching press are all manufacturers need for commissioning. Parameterization is also effortless. “This way, we ensure system availability and increase overall efficiency – and at the same time enable manufacturers to carry out easy, precise quality assurance,” says Schnerr.
