MCB Automatic Assembly Machine For Mechanism Parts

Equipment Overview

The MCB  Automatic Assembly Machine For Mechanism Parts is a specialized automation solution developed for assembling the core mechanical structure of miniature circuit breakers.

The mechanism system is responsible for the tripping function, switching operation, and mechanical reliability of an MCB. It typically includes critical components such as moving contacts, brackets, torsion springs (small and large), and latch mechanisms. The precision and consistency of these assemblies directly impact the circuit breaker’s performance and lifespan.

Traditional manual assembly of these components is labor-intensive and prone to inconsistency, especially when dealing with spring installation and latch positioning, which require high precision and repeatability.

This machine integrates automatic feeding, precise positioning, servo-driven assembly, and inspection systems to achieve high-speed and high-accuracy assembly of mechanism components.

Main Functions

• Automatic feeding of contacts, brackets, springs, and latch components
• Precision positioning and alignment system
• Automatic assembly of torsion springs (small and large)
• Automatic latch mechanism installation
• Contact and bracket assembly process
• Servo-controlled assembly operations
• Assembly quality inspection system
• Automatic product transfer and discharge
• Production counting and monitoring system
• Fault detection and alarm system
