Process Overview

This solution performs automotive lever switch operation testing using an Epson C4L robot and a force sensor.

By applying a constant force, it repeatedly tests whether the lever switch operates normally, and the measured data can be used to improve final product quality.

Components

Robot	EPSON C4L 6-axis articulated robot Payload: 4 kg Max reach: 900 mm Weight: 29 kg Repeatability: ±0.03 mm
Peripherals	6-axis force/torque sensor S250N (high rigidity, high sensitivity) Rated load: 250 N / 18 Nm Resolution: 0.1 N / 0.003 Nm Measurement axes: X, Y, Z Moment axes: Fx, Fy, Fz (6-direction) Product fixing jig

Workflow

STEP 1.	Part input
STEP 2.	Repetitive lever switch testing
STEP 3.	Measurement data logging
STEP 4.	Discharge after testing
