0.02mm Repeatability 3kg Payload Collaborative Robot Arm for Electronics Assembly

0.02mm Repeatability 3kg Payload Collaborative Robot Arm for Electronics Assembly

This 0.02mm repeatability 3kg payload collaborative robot arm for electronics assembly is a six-axis cobot engineered for tight production cells where floor space, positioning accuracy and operator safety all matter at the same time. The arm body weighs only 16.4 kg, offers a 625 mm working radius and carries a 3 kg rated payload, so it mounts on a workbench, a machine frame or a mobile cart without floor reinforcement.

Each of the six joints provides plus or minus 360 degrees of travel, joint 3 is rated at plus or minus 156 degrees, and joint speed reaches 237 degrees per second. That combination lets the arm enter narrow fixtures, rotate a tool through a full circle and return without cable wrap. Repeatability of 0.02 mm keeps the taught point identical after thousands of cycles, which is what electronics assembly, screw driving, adhesive dispensing and connector insertion actually require.

Safety is built into the mechanics rather than added afterwards. This collaborative robot arm is certified to ISO 13849 PL d Cat. 3, CE, NRTL, KCs, CR, SEMI S2 and RoHS, and it holds an ISO Class 4 cleanroom rating for semiconductor, display and medical device work. Collision detection is more sensitive on this generation and maximum collision force is lower, so the arm stops on contact and most electronics assembly cells run without perimeter fencing.

Key Specifications

Advantages

• Compact 3kg payload: a 16.4 kg body and 625 mm reach fit bench-top electronics assembly cells that cannot host a conventional industrial robot.
• 0.02mm repeatability: the same taught point is held cycle after cycle, keeping adhesive beads, screw torque and connector alignment consistent.
• Six-axis flexibility: full rotation on five joints lets the arm work above, behind and below the fixture without repositioning the base.
• Fenceless collaboration: ISO 13849 PL d Cat. 3 certification and higher collision sensitivity allow safe side-by-side operation.
• Fast deployment: hand-guided drag teaching plus an open SDK shorten programming time on short-run electronics assembly orders.
• Low running cost: 150 W average power consumption and a modular joint design keep energy use and maintenance effort low.
• Clean process ready: ISO Class 4 cleanroom rating and IP54 protection suit semiconductor, medical and precision electronics environments.
• Direct tool integration: flange level 24 V supply, RS485 and analogue I/O remove extra cabling for grippers, vision and dispensing heads.

Applications

• Electronics assembly: PCB loading, screw driving, connector insertion and functional testing
• 3C production: phone, tablet and wearable module handling
• Semiconductor and display: wafer carrier transfer and cleanroom handling
• Automotive electronics: sensor and ECU assembly, inspection and labelling
• New energy: battery module pick and place and busbar fastening
• Medical devices and laboratory automation: sample handling and reagent dispensing
• Machine tending for CNC, injection moulding and stamping machines
• Quality inspection, dispensing, polishing and packaging support tasks

FAQ

Q: What payload and reach does this 3kg payload collaborative robot arm offer?

A: The arm carries a rated payload of 3 kg and reaches a 625 mm working radius, measured at the tool flange and including the gripper weight. Inside that envelope it runs at full speed and full 0.02mm repeatability.

Q: How is 0.02mm repeatability verified before shipment?

A: Every unit is laser tracked at the factory and supplied with a test report covering repeatability, joint zero position and flange run-out, so the 0.02mm figure is confirmed on your own machine rather than taken from a catalogue.

Q: Why is this collaborative robot arm suited to electronics assembly?

A: Electronics assembly needs small parts, short moves and frequent changeovers. The 625 mm reach fits inside a bench cell, 0.02mm repeatability protects fine pitch parts, drag teaching cuts changeover to minutes, and the certified fenceless design lets operators share the bench.

Q: Can the arm be installed upside down or on a wall?

A: Yes. The base accepts any mounting angle, floor, wall, ceiling or inclined, and the controller supports the same configuration. Gravity compensation and safety limits are set for the chosen orientation during commissioning.

Q: Which tools and grippers connect directly?

A: The flange provides 4 configurable digital inputs and outputs, 2 analogue inputs, optional RS485 and selectable 0/12/24 V at up to 3 A, which covers electric grippers, vacuum generators, screwdrivers, dispensing valves and 2D or 3D vision heads.

Q: Which certifications and delivery terms come with the unit?

A: ISO 13849 PL d Cat. 3, CE, NRTL, KCs, CR, SEMI S2 and RoHS plus ISO Class 4 cleanroom rating, with certificates in the shipping documents. Stock ships in 3 working days, configured arms in 15 to 25 days, minimum order one piece.

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 3 kg collaborative robot arm.
