Five Sawyer robots power flexible production in smart metering, power distribution and energy management
Wasion Group, a provider of integrated solutions in smart metering, smart power distribution and energy management in China and international markets, has deployed Rethink Robotics’ Sawyer industrial robot on its assembly line for manufacturing single-phase energy meters.
Wasion is moving forward with smart manufacturing initiatives by leveraging smart, collaborative Sawyer robots that are easy to deploy and can meet the precision specifications for the companies’ factories.
Wasion is said to produce 35 million units of various smart metering, power and energy management equipment annually. With a diversified product portfolio, Wasion’s production lines need to accommodate a variety of products in lower volumes.
The company says it has been “vigorously looking for highly flexible automation solutions in an effort to optimize production in a highly customized environment, enabling the company to meet changing market demands and expedite delivery”.
Wasion has turned to Rethink’s Sawyer, seeing it as “the answer to safe, flexible and efficient production”.
Rethink claims that, unlike other robots, Sawyer has compliant motion control, and can feel its way into precise and fragile fixtures, even if a part position changes. This feature enables adaptive repeatability, and allows Sawyer to work precisely in many environments, much like a human does, adds the company.
Liao Qianzhong, general manager of production center, Wasion, says: “We see smart manufacturing as a significant driver of our company’s growth. We are just beginning to introduce this level of automation into our manufacturing processes, and we are pioneering the practice in China. Deploying Rethink Robotics’ smart, collaborative robots will enable us to speed up our production and migrate to smart manufacturing.
“We have already seen positive results from our initial deployment of Sawyer, and we also see tremendous potential for wider use in our operations.”
With the support and training of Rethink Robotics’ designated technical team, Wasion has completed the deployment of Sawyer for its assembly line of single-phase energy meters. Sawyer robots are now used at multiple work stations: loading electric meter boxes; PCBA loading and assembling; power testing and code scanning; carrier loading and assembly and more.
Wasion says it has already measured “significant growth” since deploying the Sawyer robots in July.
Productivity has improved by 45 percent, while operational costs have decreased by 25 percent and the part defect rate has dropped by more than 50 percent.
Qianzhong says: “Wasion advocates innovation, and we encourage our team to embrace new technologies. Collaboration with Sawyer increases our employees’ efficiency and supports them to pursue innovation.
“The workers who were previously on the assembly line will be retrained and assigned to other value-adding positions.”
Wasion expects to invest RMB 159 million ($26 million) in smart manufacturing in the coming years, primarily focusing on metering and electrical equipment production, as well as research and development. The company believes robotics technologies, especially collaborative robots, will play a pivotal role in its visionary plan.
Jim Lawton, chief product and marketing officer at Rethink Robotics, says: “With the introduction of the Made in China 2025 initiative, China is aggressively addressing rising wages and gaps in productivity through smart manufacturing.
“Sawyer is playing a significant role in this transformation for companies like Wasion Group with its ability to shift between a variety of tasks, adapt to the variability of the factory and improve production quality.”
