Measuring outer diameters is vital in manufacturing. Traditionally, skilled operators measured each part individually with micrometers, but human error and high labor requirements posed significant challenges. To address these issues, Ueno Singapore offers an automated measurement solution that combines Mitutoyo’s automatic micrometer control unit, Yamaha’s SCARA robots, and DH-Robotics’ electric grippers.

Manual measurements lead to inconsistencies, even with many operators.

The idea for this automated solution originated from a request by a customer in Malaysia. They faced the challenge of measuring hundreds to thousands of parts every day. Around ten operators were required on-site, with even more staff added during peak periods to keep up with demand. To address this, Ueno Singapore, in collaboration with Mitutoyo, Yamaha, and DH-Robotics, developed and implemented this automated measurement system.

Key Advantages of Mitutoyo’s Automatic Micrometer

Mitutoyo’s Digimatic Micrometer enables precise control through motorized operation. Traditionally, adjustments were made manually by turning the dial, which inevitably caused issues such as over-compression and measurement variations, affecting repeatability. With Mitutoyo’s automatic unit, the measurement motions of skilled operators are replicated through motor control, allowing soft, consistent, and repeatable measurements. Measurement data are captured automatically and can be tracked for history management. This system addresses challenges such as skill transfer and workforce shortages, creating an environment where anyone can achieve operator-level measurement accuracy.

Work Handling with Yamaha’s SCARA Robots

For work handling, a compact Yamaha SCARA robot (high cost-performance model YK-XE) is employed. Its excellent cost efficiency enables labor savings and improved operational productivity. When paired with a six-axis robot, it also enables full automation of the measurement process.

DH-Robotics’ Electric Gripper

ワFor work gripping, the electric gripper “RGI Series” from Chinese manufacturer DH-Robotics is employed. Unlike pneumatic grippers, it requires no air source and provides high gripping force along with precise position control through electric operation. A particularly rare feature in the industry is its ability to perform gripping and continuous rotation simultaneously, making it ideal for measurement processes that involve complex movements. Compared to pneumatic models, it can operate in a variety of environments and handle multiple workpieces with a single unit, offering exceptional versatility. In real-world deployments, the gripper has received many repeat orders, underscoring its practicality and convenience.

Skilled-Operator Accuracy for Everyone: Three-Company Collaborative Automated Measurement Solution

This automated measurement solution enables consistent measurements, independent of operator skill. By feeding measurement results back into the manufacturing process, it helps . Additionally, it. Ueno Singapore will continue supporting its customers by offering automation solutions that integrate the latest measurement technologies with robotic systems.
