What is a micro motor assembly line?

It is an automated production line for small DC or universal motors used in consumer electronics, automotive accessories and toys.

Are Jiuju micro motor lines high speed?

Yes, compact indexing systems and high-speed stations support large-volume production.

Automated assembly line solutions for micromotors

Micro-motor automated assembly line solution for micro-motor diameter ≤ 5mm precision production needs, covering the rotor winding, spot welding, magnet assembly, assembly, performance testing of the whole process, the integration of micro-winding machine, vacuum suction nozzle assembly mechanism, with micron-level vision alignment, high-precision force-controlled assembly technology, to complete the winding and welding of ultra-fine enameled wire of 0.02mm, and at the same time supporting the anti-static treatment, on-line The solution is accompanied by anti-static treatment, on-line full inspection and MES data traceability system. The program will increase the product yield from the traditional manual 80% to 99.5%, the defective rate down to below 0.1%, increase production efficiency by 3 times, support multi-specification quick changeover, and solve the pain point of manual assembly of micro-parts, which is difficult to assemble and lack of precision.

Customization Process

Customized to the size and tolerances of micro parts; vacuum pick-up, micron-level vision alignment and ESD handling are all redesigned. Seven stages, each with defined deliverables and customer sign-off points.

1
Requirement review
& concept design
7–15 days
Technical proposal
2
Technical freeze
& contract
3–7 days
Technical agreement
3
Design & build
in-house commissioning
30–60 days
Drawings · programs
4
FAT
factory acceptance
3–5 days
Acceptance record
5
Site installation
& SAT
5–10 days

7
Final acceptance
& handover
2–3 days
Manuals · spares

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, the 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, adapt to the flexible production needs of multi-specification micro-motor.
