With the continuous development of postal services, the transportation of postal items presents characteristics such as significant workload fluctuations, high dynamism, frequent adjustments to operational processes, and monotonous handling operations. Its efficiency in receiving, transporting, sorting, and warehouse delivery largely determines logistics efficiency.
Shanghai Quicktron Intelligent Technology Co., Ltd.'s AGV system provides customized smart logistics solutions tailored for the postal industry, significantly improving mail and parcel transmission speed and sorting efficiency.
Beijing Hollysys Motor Technology Co., Ltd. customized and developed the SM series low-voltage servo integrated machines for the movement and lifting control of Quicktron's postal transmission and sorting AGV system.
SM Series Low-Voltage Servo System Features:
-
Compact structure: Integrates low-voltage servo motor, driver, and encoder into a single unit with a smaller footprint, saving installation space. Certain models also feature integrated brake and gearbox designs.
-
High reliability: Eliminates connection cables and connectors between motor and driver, reducing potential risks of poor contact or disconnection; simplified wiring avoids electromagnetic interference.
-
Cost reduction: Eliminates motor-to-driver connection cables, effectively lowering system costs;
-
Strong networking capabilities: Supports CANOpen, custom CAN communication, and RS485 communication;
-
Customizable functions to meet market requirements; Flexible design modifications: The same drive component can be paired with different motors to create various integrated units, meeting diverse field requirements.
