At Vision Stuttgart 2024, VICO Imaging will showcase its machine vision application with a robotic arm featuring COOLENS® MFA121 and WWT series. Additionally, there will be an automated sorting vision system demonstration featuring our 360° series. This is our first sneak peek of the exposition. Today we will introduce the robotic arm application and 360° view inspection.
Part One – MFA121 & WWT Series in Robotic Arm Application
About the robotic arm application
Industry 4.0 is a new revolution featuring the organic merge of digital technologies and traditional manufacturing. The industrial robotic arm is the major theater of this revolution, for it redefined how manufacturers operate and shaped the future of factory automation.
The robotic arm acts as the bridge between physical production and digital information. These arms are “armed” with revolutionary sensors and software, making sure they collaborate seamlessly with their human co-workers, other compatible systems, or even other robotic arms. Compared to their traditional counterparts, they bring unparalleled precision, efficiency, flexibility, and maximum repetition capability. These properties enable robotic arms to perform complex and delicate operation tasks perfectly, adaptable to various complex manufacturing conditions and requirements.
Robotic arms are widely used in many industries, including but not limited to automobile manufacturing, electronic manufacturing, food processing, etc. With the advancement of technology and the expansion of application scenarios, robotic arms have gradually expanded to medical, agricultural, aerospace, and other fields.
In a word, robotic arms play a vital role in industrial automation, because they not only improve production efficiency and product quality, and reduce labor costs, but also improve manufacturing conditions, promote industrial upgrading, and enhance corporate competitiveness.
The role of FA lens in robotic arm application
In the industrial automation process of assisting robotic arms, it is crucial to choose a good FA lens to obtain the best performance and precise control.
COOLENS’s MFA and WWT series surpass other brands with excellent resolution, contrast, and relative illumination. As a unique FA lens, the WWT series has a fixed aperture, fixed focal length, and fixed working distance. This not only provides excellent image quality but also gives it outstanding anti-vibration performance. Overall, these two series are highly suitable for sorting with robotic arms.
