1250mm Reach 12kg Payload Collaborative Robot Arm for Automotive Parts Assembly

1250mm Reach 12kg Payload Collaborative Robot Arm for Automotive Parts Assembly

This 1250mm reach 12kg payload collaborative robot arm is configured for automotive sub-assembly, where parts arrive at awkward angles and the operator works in the same space. A 1250 mm working radius, 12 kg rated payload and 0.03 mm repeatability let one arm present, hold and fasten components that would otherwise need two fixtures.

The third joint turns at 267 degrees per second, the fastest in the i-Series, which shortens the wrist reorientation between fastener positions and keeps a multi-spindle screw driving sequence inside takt time. With 3.8 m/s tool speed and a 40.6 kg body on a 218 mm base circle, the arm is stable enough for torque reaction without a heavy pedestal.

Certification covers the automotive audit trail: ISO 13849 PL d Cat. 3 functional safety, CE, NRTL, KCs, CR, SEMI S2 and RoHS, plus an ISO Class 4 cleanroom rating for electronics sub-assembly areas. The open platform talks to line controllers over Ethernet, ModBus, Profinet and EtherNet/IP, and the same SDK that scripts a fastening sequence also exposes tool data for traceability records.

Key Specifications

Advantages

• 1250mm radius: reaches across an engine, a door module or a battery tray from one fixed position.
• 12kg payload: supports multi-spindle screwdrivers, servo presses and servo grippers with cabling.
• 267 degrees per second on joint 3: fastest wrist reorientation in the series, cutting index time between fasteners.
• 0.03mm repeatability: holds thread engagement and press depth within tolerance across a shift.
• Torque reaction stability: a 40.6 kg body on a 218 mm base circle resists reaction from powered drivers.
• Collaborative layout: certified force and speed limits let an operator load parts beside the running arm.
• Traceability ready: open SDK and fieldbus options expose torque, position and result data to the line system.
• Series commonality: same controller, teach pendant and programming environment as every other i-Series model.

Applications

• Automotive sub-assembly: bracket, module and trim fastening
• Screw driving and nut running on powertrain and chassis parts
• Press fitting of bearings, bushings and seals
• Battery pack assembly and busbar fastening
• Door, seat and instrument panel component handling
• Vision guided part presentation before fastening
• Torque controlled assembly with result logging
• End-of-line functional test handling and labelling

FAQ

Q: What makes this 12kg payload collaborative robot arm suitable for screw driving?

A: Three things: a 12 kg payload that carries a multi-spindle driver and its cable, a 267 degree per second third axis for fast reorientation between screws, and 0.03 mm repeatability so the bit engages the thread consistently. Torque and angle data are exposed through the SDK for traceability.

Q: How much reach is available with a tool fitted?

A: The 1250 mm radius is measured at the tool flange. A typical 150 to 250 mm driver assembly therefore leaves roughly one metre of usable reach from the base, which suits most automotive sub-assembly fixtures.

Q: Can the arm work safely beside operators?

A: Yes, where a risk assessment allows. The arm is certified to ISO 13849 PL d Cat. 3, force and speed limits are configured in software, and collision detection stops motion on contact, so operators can load fixtures without a full fence.

Q: Which fieldbus connects to the line PLC?

A: Ethernet and ModBus-RTU or ModBus-TCP are standard, with Profinet and EtherNet/IP available as options. Digital I/O at the cabinet provides 16 inputs and 16 outputs with 8 safety channels for handshakes.

Q: Is cleanroom operation possible?

A: Yes. The arm carries an ISO Class 4 cleanroom rating, which covers sensor and electronics sub-assembly areas inside an automotive plant.

Q: What is the ordering process?

A: Send the fastener list, torque values and fixture layout for a configuration review. Minimum order one piece, stock ships in 3 working days, configured arms in 15 to 25 days, with calibration report and 12 month warranty.

Q: How do I request a quotation?

A: Send your part weight, cycle requirement, fixture layout and plant voltage. Our engineers confirm the payload and centre of gravity margin, propose the end effector and mounting arrangement, and return a price, lead time and integration drawing for this 12 kg collaborative robot arm.
