Automated precision assembly of motor stators and gears

The servo press accurately presses the stator and rotor, and the robot automatically grabs the gears and locks the brush components, monitors the pressing force curve in real time, and automatically alarms and shuts down if the gear is misaligned or the brush is stuck, eliminating stuck motor operation.

Power-on endurance test under load conditions

Simulate the load resistance of the vehicle's wiper, and the motor starts and stops continuously for 30 minutes. The no-load, load current, and output torque are collected in real time to identify early failure problems such as coil short circuit, gear wear, and poor brush contact.

NVH silent noise detection

The workpiece is automatically sent into a closed soundproof cabin, and the motor operates in all gears at high and low speeds to collect the noise spectrum. The system compares the standard noise curve to accurately capture gear friction and bearing abnormal noise defects, thereby avoiding customer complaints about abnormal noise from the wiper while the vehicle is running.

Visual appearance defect detection

Industrial cameras detect shell bumps, missing brushes, damaged wiring harnesses, and improperly assembled gears. Defective products are automatically diverted and defect images are archived for process optimization.

Single piece quality data traceability

Each motor is bound to the casing QR code, and assembly pressure, torque, current, and noise detection data are stored locally for 10 years. It is connected to MES to realize full-link quality traceability of parts and components, meeting the IATF audit requirements of the OEM.

Commercial value: The abnormal noise and stuck defect rates of the wiper motor after leaving the factory have been reduced by 92%. A single piece of equipment can replace three assembly and inspection workers; the compact single machine does not require a large-area factory building, and small and medium-sized parts factories can flexibly invest in trial production and mass production.

Automated assembly of door handle parts

The vibrating plate automatically feeds the lock cylinder, return spring, and induction wire harness. The servo tooling accurately presses the buckle and wire harness terminal, and monitors the press-fitting in place signal in real time. If the spring is missing or the terminal is empty, it will automatically alarm and isolate defective products.

Mechanical opening and closing durability and feel testing

The servo motor simulates the manual opening and closing of the door handle, and cycles 5,000 opening and closing cycles to collect the opening and closing torque and rebound strength to identify defects such as insufficient spring force and stuck lock cylinders to prevent customers from using door handles that have weak rebound and stuck doors.

Keyless induction electronic control function test

The equipment simulates the vehicle's low-frequency induction antenna signal, detects the unlocking sensitivity and signal transmission stability of the door handle induction module, verifies the unlocking performance under low temperature and weak signal conditions, and screens out induction module failure parts in advance.

Assembly gap visual inspection

The high-definition vision camera scans the door handle assembly gaps and automatically determines whether the gaps comply with the OEM drawing tolerances. Workpieces with excessive gaps are automatically diverted to ensure assembly consistency in the appearance of the entire vehicle.

Whole-process quality data traceability

Each door handle is bound with an exclusive QR code, and the spring pressing force, opening and closing torque, induction signal, and gap values are all uploaded to MES to completely record the entire production and inspection process and meet the quality traceability standards for body parts.

Commercial value: After-sales faults such as door handle rebound and stuckness and sensor failure are reduced by 86%, and poor assembly gaps are completely eliminated; a single machine replaces four assembly inspection workers, and the quick-change fixture adapts to the simultaneous production needs of multiple models of car companies.
