Product Details
In today’s wave of intelligent manufacturing, efficiently and precisely automating the loading and unloading of workpieces with multiple specifications has become a critical step in boosting production efficiency. Recently, Qianhao Automation successfully addressed the complex operational challenges faced by a roller-processing enterprise by leveraging its innovatively developed QEPA-C40 electro-permanent magnet. This solution provides an efficient and stable suction method for robotic end-effectors, drawing widespread attention across the industry.
Operational Challenge: Multiple specifications and uneven adsorption surfaces—traditional fixtures simply can't handle it.
This customer primarily engages in rough machining of rollers, with a wide range of workpiece specifications—including diameters from 15 mm to 70 mm and lengths from 22 mm to 150 mm—and the maximum weight of a single part can reach 5 kg. What makes the task even more challenging is that the workpieces have striped textures on their suction surfaces, resulting in uneven surfaces. Traditional vacuum suction cups or electromagnets tend to provide unstable adhesion due to insufficient contact, and may even scratch the workpiece surfaces. Moreover, frequent changes of fixtures to accommodate different specifications further increase downtime and costs on the production line.
Qianhao Solution: QEPA-C40 Electromagnetic Permanent Magnet, Precisely Tailored to Meet Your Needs
Addressing this pain point, Qianhao Automation has launched the QEPA-C40 robotic manipulator electric permanent magnet suction cup, which has become the customers’ top choice thanks to its three core advantages:
Strong suction power combined with a lightweight design: The rated suction force reaches 20 kg, far exceeding the maximum workpiece weight, ensuring firm and reliable adhesion. Its self-weight is only 0.7 kg, reducing the load on the robotic arm and enhancing its operational flexibility.
Adapting to Complex Surfaces: Electromagnetic permanent magnet technology uses magnetic fields to penetrate the surface texture of workpieces, enabling non-contact, high-force adsorption without causing scratches. It is also compatible with rollers of varying diameters and lengths.
Energy-efficient and highly efficient: Operating voltage is DC 105V, and operating current is DC 7A. Its energy consumption is only one-third of that of conventional electromagnets, and it can maintain suction force without continuous power supply, thereby reducing long-term operating costs.
Application results: Efficiency increased by 30%, and the failure rate dropped to zero.
Since deploying the QEPA-C40, the customer’s production line has achieved a breakthrough in “one fixture for multiple specifications,” reducing the robotic arm’s changeover time to under one minute and boosting overall loading and unloading efficiency by 30%. More importantly, adsorption stability has been significantly enhanced, driving the equipment failure rate caused by workpiece drop-off down to zero and ensuring consistent product surface quality. The customer’s technical director commented: “Qianhao’s electro-permanent magnets not only addressed our core pain points but also, thanks to their modular design, leave ample room for future capacity expansion.”
Industry Outlook: Automated Electropermanent Magnets Empowering the Upgrade of Intelligent Manufacturing
As the manufacturing industry increasingly demands flexible production, cost reduction, and efficiency enhancement, electromagnetically actuated permanent magnet fixtures are becoming the “new favorite” in the field of automated loading and unloading. For 18 years, Qianhao Automation has been deeply engaged in electromagnetically actuated permanent magnet technology. Its products are now widely used in industries such as automotive components, aerospace, and precision machining, serving a total of over 5,000 customers. The successful application of the QEPA-C40 once again demonstrates the irreplaceable value of electromagnetically actuated permanent magnets in complex operational conditions.
