Solution

Windshield wipers are a crucial component for safe driving, installed on the windshield. They remove rain, snow, and dust that obstruct vision, keeping the windshield clean. A windshield wiper system consists of a wiper blade assembly, a wiper motor, a drive lever, and a wiper switch. Driven by a motor, the wiper speed is controlled by adjusting the current to the speed setting (high or low speed), which is then converted into the reciprocating motion of the wiper blade assembly via a linkage mechanism

wiper circuit

The assembly quality of the wiper motor directly affects wiping performance and driving safety. Wiper motor production involves multiple precision processes, including feeding, riveting, screw riveting, magnetizing, dispensing adhesive, applying grease, and tightening. To ensure that each motor completes the entire process according to standards and achieves process and planning verification, it is necessary to record assembly parameters (such as pressing force) and test results (image/run-in/photoelectric detection). This comprehensive quality data supports traceability and problem investigation, creating a closed-loop data system

Solution

To ensure the safe operation of automobiles, every component is directly related to human life. Safety is paramount, therefore all automotive components require full-process production records for traceability and visualization. Given the technological characteristics of motor assembly (multiple processes, high precision, and strong compliance), an intelligent solution covering "process verification, data acquisition, and visualization" is needed

Huamao Auto's RFID high-frequency reader + tag combination is integrated into motor production. Each wiper motor is equipped with a unique RFID tag, serving as a "digital ID card." High-frequency readers are deployed at key workstations such as riveting, screw riveting, magnetization, and testing. As the motor passes through these workstations, the tag is identified, and the process execution status, key parameters, and test results are recorded. The reader synchronizes the collected information to the production management system while simultaneously writing it to the local storage of the motor's unique ID card – the tag

Application effect

  Precise control of process compliance:Huamao Auto RFID automatically verifies the execution of processes to prevent "missed processes" and "wrong processes". Key parameters such as pressing force are recorded in real time to avoid human operation errors and ensure the consistency and pass rate of motor assembly.

  Upgraded quality control efficiency:The system automatically collects the entire process data of Huamaoote labels, eliminating the need for manual data entry and reducing recording errors by more than 90%; when quality problems occur, the problematic process and batch can be quickly located through the labels, shortening the investigation time by 80% and reducing recall costs.
