Increase Quality Testing Numbers

Problem

Sennheiser Manufacturing USA produces professional audio equipment, which involves assembling thousands of different PCBs. Their meticulous process of manual PCB testing became a bottleneck on the production floor.

Solution

Sennheiser used Robotiq’s 2F-85 Adaptive Gripper to handle 115 different PCBs and saw a 33% increase in the number of units tested. They also used Robotiq Insights to track daily production metrics, and the resulting data helped justify adding a second Universal Robots cobot in summer 2019.

“The cobots are fast, but I can keep up—and it’s great how much we’ve increased our numbers.”

Marcella Segovia PCB testing operator, Sennheiser Manufacturing USA

“I use Insights to communicate information to non-engineering people, because I can just point to the dashboard and explain what’s going on.”

Steven Nery Manufacturing engineer, Sennheiser Manufacturing USA

“I get daily reports of his tests and receive all alerts if the robot stops. So if there’s a problem, we’re able to attack it very quickly.”

Roger Case Test engineer, Sennheiser Manufacturing USA

“Robotiq had a unique solution: a reliable gripper that can manage part changeovers quickly, which was important for our high-mix, high-volume production.”
