Brush motor automated assembly line solutions

Brush motor automated assembly line solution covers the whole process of rotor processing, commutator press fitting, brush assembly, welding line, final assembly and performance testing. For the structural characteristics of brush motors, it integrates the laser alignment assembly technology to ensure the contact angle between brush and commutator is accurate and consistent, and matches with the servo press fitting, automatic soldering, on-line inspection and other processes, and realizes the whole process of data management and control and NG through PLC+MES system. The PLC+MES system realizes data control of the whole process and automatic sorting of NG products. The whole line of this program can reach a crop rate of 90% or more, the assembly efficiency is 30% higher than the manual line, only 2-3 operation and maintenance personnel can replace the traditional more than 20 artificial, effectively reducing the product defective rate; the modular design supports the rapid change of type within 15 minutes, compatible with the production of brushed motors in many areas of the mixed production, and solves the quality fluctuations of the traditional manual assembly of the pain points.

Customization Process

Customized to the commutator, brush and end-cap structure of the brushed motor; press-fitting, soldering, laser alignment and performance testing are all redesigned. Seven stages, each with defined deliverables and customer sign-off points.

Total lead time is typically 45–120 calendar days, with build and in-house commissioning accounting for the largest share. Once the design is frozen, changes to core process parameters (size, cycle time, number of stations) cascade into mechanical, electrical and layout changes and may extend the schedule by more than 30% — technical freeze requires written customer confirmation.

Program Advantages

The program can improve the repeat positioning accuracy to ± 0.01mm, product defective rate down to below 0.3‰; modular design supports 25 minutes of rapid type change, compatible with the mixed line production; the whole process of data traceability, unmanned operation, compared with the traditional production line, production capacity and stability significantly improve, effectively reduce labor costs, suitable for multi-specification brush motors flexible production needs.
