Smart object inspection: Thanks to Deep-Learning algorithms, Baumer AX Smart Cameras will detect macro and micro cracks in mechanical mounting elements
One of the world's leading manufacturers of mechanical fastening equipment and cold-formed parts seeks to improve quality inspection. The solution: Software with Deep-Learning algorithms in combination with the innovative Baumer AX Smart Camera.
The Italian Gruppo Vescovini S.p.A. with affiliate SBE-VARVIT is one of the world's leading manufacturer of connecting elements, mechanical fasteners and cold formed parts for varied industries. Headquartered in Reggio Emilia, with five production locations in Italy and one in Serbia, the Group acts as a full-service provider servicing more than 5,000 customers worldwide, among them every major original equipment manufacturer in the industry of automotive, heavy duty, construction and industrial machinery.
Intelligently controlling a compact system
One of SBE-VARVIT’s challenges is product quality control throughout the entire manufacturing chain at the tail end of process lines. Doing so required a compact system for intelligent quality control of washers without operator intervention. High standards had to assure the final product quality and safe downstream processes in parallel.
Optical quality inspection paired with artificial intelligence
To meet the SBE-VARVIT requirements, software company beanTech was in charge with the development of an optical quality control solution based on artificial intelligence (AI). A hybrid technology combining image processing algorithms and artificial intelligence runs directly on a Baumer AX Smart Camera. The AX Smart Cameras merge robust industrial camera quality, NVIDIA Jetson AI modules and high-performance Sony CMOS sensors into a freely programmable platform for vision-at-the-edge and AI applications.
100 percent reliability without operator intervention
These are the best prerequisites for innovative quality control. The beanTech software solution in cooperation with the Baumer AX Smart Camera ensures reliable detection of any defect type, from macro to micro cracks at 100 percent production volume. Furthermore, when changing products, the solution will automatically reconfigure by identifying the item in production and loading the appropriate model, without any operator intervention or system data source interfacing.
Image processing “at-the-edge“ straight on the freely programmable AX Smart Camera forms a compact system comprising only limited components. Installed straight in the production line it saves time and costs. The Baumer AX Smart Camera with Linux-based operating system simplifies software engineering work with well-known standard libraries and comprehensive performance capacities for both AI and conventional image processing at high frame rates thanks to integrated NVIDIA Jetson technology.

The beanTech software combined with a Baumer AX Smart Camera fully met the SBE-VARVIT requirements and challenges of quality assurance. “We at SBE-VARVIT, a member to the Vescovini Group, have always believed in innovation. For accessing Artificial Intelligence in our production structure we required the support of experts experienced in the complexity and reality of industry context. beanTech has proved a valid partner in shaping the future we have envisaged for our industry with creativity and tenacity”, says Alessandro Vescovini, CEO SBE-VARVIT.

Guiseppe Parisi, Sales Engineer at beanTech, highlights the role of partnership for successfully completing such a project: “Right from the beginning, the common way with SBE-VARVIT started introducing a quality control system.” From this very beginning, he says, SBE-VARVIT proved to be a competent partner, driven by growing ambition and the need for implementation of AI throughout the entire plant location. “Working with someone having such a clear vision is inspiring and lays the foundation for mutual growth”, Parisi said.

The quality inspection at SBE-VARVIT clearly shows how Baumer creates added customer value by innovative vision solutions such as AX Smart Camera. “This solution impressively shows how modern image processing can contribute towards today’s product quality assurance”, says Peter Felber, Product Manager AX Smart Cameras at Baumer.
The smart combination of conventional image processing and AI algorithms by software specialist beanTech allows for extreme flexibility in quality control without the need for operator intervention. “Here, the AX Smart Camera provides a platform developed for industrial applications enabling “all-in-one” solutions for “at-the-edge” image processing. This substantially simplifies inline integration at production facilities,” explains Peter Felber.
