This assembly automation solution utilizes the Epson N2 robot and FT (Force-Torque) sensors to automate the highly difficult process of inserting Flex Cables into PCB connectors.

It is the optimal solution for performing high-precision assembly tasks while minimizing cycle times within confined workspaces. This project was initiated to automate the Flex Cable insertion process, which previously relied entirely on manual labor.

Components

Robot

  • Robot: EPSON N2 (6-Axis Articulated Folding Arm)

    • Unique Design: Innovative folding-arm structure that reduces the workspace footprint by approximately 40%.

    • Payload: 2.5kg (Rated: 1kg)

    • Reach: 450mm

    • Weight: 19kg

    • Repeatability: ±0.02mm

  • Force Sensor: Integrated FT sensor for real-time tactile feedback during insertion.

Workflow

STEP 1.
Loading: The robot picks the PCB and places it into a fixed assembly jig.
STEP 2.
Preparation: The robot opens the Flex Cable connector clip on the PCB.
STEP 3.
Pre-alignment: The Flex Cable is picked and placed onto an alignment jig.
STEP 4.
Precise Insertion: The aligned Flex Cable is re-picked and carefully inserted into the PCB connector using force feedback.
STEP 5.
Locking: The robot closes the connector clip and proceeds to the next cable.
STEP 6.
Unloading: Once all cable insertions are complete, the PCB is moved to the finished goods rack.
