The typical robotic stamping automation production line consists of several key components, including the robot, electronic control system, unloading device, conveyor belt, sheet washer, sheet oiler, centering station, end palletizing system, safety protection system, and the robot’s end effector. The layout can be customized based on the size and configuration of the production workshop. For instance, the unloading method can either align parallel to the press line or be arranged perpendicularly depending on the space and workflow requirements.
Stamping robots are specifically designed to handle high-load operations with precise movement and consistent performance. Unlike general handling robots, they must also manage frequent start-stop cycles, large working areas, and accommodate oversized workpieces. To meet these demands, manufacturers have enhanced motor power, upgraded reducer specifications, extended arm lengths, and implemented more robust scaffolding structures for improved stability and reach.
The control system of a robotic stamping line is highly integrated, combining presses, robots, destackers, washing machines, oilers, centering stations, material detection systems, visual identification tools, conveyor belts, and safety mechanisms. These systems often interface seamlessly with the plant's MES (Manufacturing Execution System) via Ethernet and industrial fieldbus networks. Safety buses may also be included in the fieldbus system to ensure safe operation in hazardous environments.
There are three common types of unloading systems used in stamping lines: dedicated unloading machines, robot-assisted unloading with a trolley, and truss-type manipulators combined with a trolley. Each has its own advantages depending on the application and space constraints.
The retractable conveyor belt plays a crucial role in transporting individual sheets after unloading. It ensures the correct speed for the subsequent washing and oiling processes, typically controlled via frequency conversion to maintain synchronization. The belt length is adjustable, allowing it to adapt to different operational conditions.
Sheet washing machines are essential for maintaining the quality of materials before stamping. As automotive manufacturers demand higher surface standards, pre-stamping cleaning has become a standard process. Cleaning methods can be either online or offline, depending on the production scale. Online systems are larger, often up to 4.2 meters, while offline systems are more compact, suitable for smaller batches.
The oiling machine applies lubricant to the sheet before stamping, ensuring smooth forming and reducing wear. It includes spray nozzles, oil supply units, gas delivery systems, and automated controls to maintain consistent oil distribution. The system can be moved offline when not in use, and the oil temperature is regulated for optimal performance.
To ensure accurate placement in the mold, sheets must be centered before being picked up by the robot. There are three main centering methods: gravity-based, mechanical, and optical. Gravity centering relies on the natural sliding of the sheet, while mechanical centering uses pushers and sensors for precise alignment. Optical centering, a newer technology, uses cameras and software to adjust the robot’s path, offering cost-effective and efficient positioning.
The robot’s end effector, or tooling, is critical for handling and placing the sheet accurately. In some cases, a seventh axis is added to the robot to increase productivity, allowing the line to produce up to 12 pieces per minute—comparable to high-speed dedicated systems.
Finally, at the end of the line, an automated coding system helps manage high output rates. When the production cycle exceeds 10 pieces per minute, manual intervention or robotic coding is used to label and transport finished parts efficiently, ensuring smooth downstream operations.
