20kg Payload 1647mm Reach Dual-Gripper Collaborative Robot Arm for Press Tending

20kg Payload 1647mm Reach Dual-Gripper Collaborative Robot Arm for Press Tending

The AUBO iS20 is the press tending configuration of the iS standard series: a 20kg payload 1647mm reach collaborative robot arm with 0.05mm repeat positioning accuracy. What separates this build from a general-purpose unit is 20kg of payload that carries a double gripper, so a blank goes in as the finished part comes out. The body is sealed to IP54, runs on the AUBO-CB-iS controller with a 1kg teach pendant, and is assembled from six standardised joint modules, so a 20kg payload collaborative robot arm can be maintained with one spare parts list across every cell on your floor.

Technical Specifications

Why This Build Suits the Job

• 20kg payload at 1647mm reach: 20kg of payload that carries a double gripper, so a blank goes in as the finished part comes out, which is the number that decides whether the cell needs a second unit.
• IP54 sealed body: dust, splash and process mist stay outside the joint modules; IP67 optional for this application.
• Stable under load: the balanced structure and updated control loop limit vibration at 3.7m/s tool speed, so accuracy holds through a full shift rather than the first hour.
• Six standard joint modules: a joint replacement on this collaborative robot arm is one part number and a short stop, not a rebuild of the whole arm.
• Open fieldbus and SDK: Modbus-RTU/TCP, PROFINET, EtherNet/IP plus ROS and ROS2 let your engineers join the 20kg payload collaborative robot arm to an existing PLC, vision system or MES.
• Any-angle mounting: floor, wall or inverted installation with a 260mm base keeps the layout flexible when floor space is already taken.

Typical Application Fields

• Power press and hydraulic press load and unload
• Double gripper blank and formed part exchange
• Press brake and bending cell tending
• Injection molding take-out of mid-weight parts
• Heavy sub-assembly and press-fit operations
• Buffer stock and pallet handling next to the press
• Industries: 3C electronics, home appliances, auto parts, hardware, food and daily chemical, warehousing and logistics

Frequently Asked Questions

Q1: Why this configuration for press tending?

A double gripper is what makes press tending pay. With 20kg payload this arm carries two grippers plus a formed part, so the blank goes in on the same cycle the finished part comes out, and 1647mm reach covers the press bed and the buffer pallet.

Q2: How is accuracy held over a full shift?

Repeat positioning accuracy is 0.05mm at the tool flange under rated payload, and each 20kg payload collaborative robot arm ships with a calibration report from the factory test. Accuracy is only useful if it survives production, so the structure, the control loop and the sealed joints are tuned together to hold that figure at 3.7m/s tool speed rather than on a lab bench, which is the difference between a demo and a production-ready collaborative robot arm.

Q3: What environment can the iS20 work in?

The arm body is rated IP54 (IP67 optional), the controller IP43 and the pendant IP54. That covers workshop dust, light splash and process mist outside a direct spray zone. The joints are sealed modules with no exposed belts and no grease channel to re-pack, which is what keeps this collaborative robot arm in service on lines where conventional arms need monthly attention, and that record is why buyers shortlist this collaborative robot arm for wet and dusty cells.

Q4: How do we integrate the arm with our line controls?

The controller runs on 115/230VAC, links to the arm over a 5m cable (8m maximum) and speaks Modbus-RTU/TCP, PROFINET and EtherNet/IP. Programming is open, with C, C++, C#, Lua, Python, JavaScript, Java, ROS and ROS2 on Windows and Linux, or point recording on the 1kg pendant. First installation and program validation for one cell typically takes 2-3 days with our support.

Q5: What documentation and programs ship with the unit?

One arm body, one AUBO-CB-iS controller, one AUBO-TP-iS pendant with a 4m cable, the arm cable set, the user manual, interface documentation, a wiring diagram and a calibration report. For this application we also provide press tending example programs, safety-zone wiring notes and gripper I/O mapping, so your team can validate the cycle before the 20kg payload collaborative robot arm is installed.

Supply and Support

Arms are assembled at the AUBO manufacturing bases in Changzhou and Zibo and function tested before packing, then shipped in an export plywood case with shock-absorbing foam; arm body, controller, pendant and cables travel in separate compartments. Standard delivery is 15-25 working days after deposit, and because every iS model shares the same controller and joint modules, a second collaborative robot arm cell can be rolled out with the same spare parts list and the same programs, so a second collaborative robot arm cell starts from a known baseline instead of a fresh integration project.
