Automated quality inspection solution for fasteners

29 November 2021

Universal Robots has helped Stanley Engineered Fastening to introduce robotic quality inspection using cobots in its Warrington facility in the UK.

Fifteen UR3e cobots act as key components in new cells for Breakstem autonomous manufacture which have reduced product costs by approximately 10% and shortened lead times by up to 70%. They are producing approximately 350 million fasteners per annum from across the company’s product range.
 
The new cells integrate four previously independent processes – boosting productivity and improving conditions for machine operators. Within the manufacturing process a cobot randomly selects a component for batch sampling and performs a pre-programmed quality inspection. This involves degreasing, drying, deburring and feature inspection through a digital micrometer. The cobot then performs an automated destructive test by placing the part in a Stanley Smart Gun to record the break load of the components.
 
Commenting on the automation of this process, Vitalij Rodnov, advanced manufacturing engineer at Stanley Engineered Fastening, said: “We needed to increase throughput and productivity in order to meet demand across our fastener product range. Freeing up our machine operators from this repetitive task allows them to add more value elsewhere in the process, delivering better profitability and shorter lead times.”
