Process Overview

This small-parts assembly automation solution uses an Epson N6 robot and an FT (Force-Torque) sensor to automate the assembly process for small M1 bolts.

For M1-class bolts, even minor positional deviations can easily lead to assembly failure, and if the bolt is not assembled with the proper force, it may result in part damage or misassembly. By combining Epson’s N6 robot with an FT sensor, this solution minimizes positioning errors and monitors force during operation to ensure stable assembly performance.

This solution is optimized for achieving both precise assembly and minimized takt time in limited space.

This project was implemented to automate the assembly process of micro bolts.

• Enables precise micro bolt assembly operations

• Performs accurate fastening based on target torque by applying an FT sensor capable of detecting 0.1 N / 0.003 Nm

• Enables precision bolting for M1-size bolts by applying high repeatability

• Prevents bolt damage through precise force sensing

• Enables stable assembly even with part shape variation by applying controlled force

• Ensures high-precision assembly without misalignment even in pre-assembly processes

• Enables compact installation

• Minimizes required floor space through ceiling-mounted robot cell design

• Minimizes operator footprint through folding-arm structure

• Minimizes takt time through high-speed, high-efficiency motion

• Enables high-speed operation with a maximum joint speed of 537.8 deg/s

• Shortens cycle time by enabling shortest-path movements even in confined space through folding-arm structure

• Provides assurance through quality warranty coverage

• Provides 1-year warranty service support
