What is an MCB Cage Terminal Automatic Assembly Machine?
Ан MCB cage terminal automatic assembly machine is a specialized automated system for assembling cage‑type terminals used in miniature circuit breakers. Cage terminals consist of a metal cage and a screw that, when tightened, secure electrical wires. Manual assembly is prone to inconsistent torque, cross‑threading, and missing components – leading to loose connections and field failures. This machine automates the entire process: terminal parts are fed, aligned, and screwed together using a servo‑controlled electric driver. Real‑time torque monitoring ensures each screw is tightened within a programmable window. Defective assemblies (e.g., cross‑threaded or under‑torqued) are automatically rejected. The machine is essential for high‑volume production where consistent electrical contact resistance and reliability are critical. As a non‑standard custom solution, we adapt the machine to your specific terminal geometry, screw size, and production targets.
Vibratory bowl feeders for cage and screw components.
Programmable torque (0.5‑5.0 N·m) and speed, ±5% accuracy.
Detects cross‑threading, missing screws, or insufficient tightness.
Rapid changeover between different terminal sizes (under 20 minutes).

Основные технические преимущества
Eliminates manual torque inconsistency
Manual screwdriving leads to torque variations that cause loose connections or stripped threads. The servo driver applies the same torque (±5% accuracy) on every terminal, ensuring consistent electrical contact resistance and fire safety.
Real‑time cross‑thread detection
The torque monitoring system detects abnormal torque curves (e.g., sudden drop or spike). If cross‑threading or missing screw occurs, the machine rejects the part instantly, preventing defective units from reaching customers.
Quick changeover for different terminal sizes
Different MCB current ratings use different cage and screw sizes. Quick‑change tooling (feeder outlets, screwdriver bit, nest) and recipe‑based parameters allow changeover in under 20 minutes.
Full production traceability
Each assembled terminal’s torque value, cycle time, and pass/fail result can be logged and linked to a barcode. Data export via USB or MES interface supports quality audits and process improvement.
Customer Success Story – MCB Manufacturer
A leading MCB manufacturer was manually assembling cage terminals at 600 units per shift with a 3% defect rate (cross‑threaded or loose screws). After installing our automatic cage terminal assembly machine, they achieved:
The machine paid for itself in 6 months and eliminated customer complaints about loose terminal screws.

Часто задаваемые вопросы
The servo screwdriver provides programmable torque from 0.5 to 5.0 N·m, suitable for most MCB cage terminals (M2 to M5 screws). Custom torque ranges up to 15 N·m are available for larger terminals.
The torque monitoring system compares the real‑time torque curve with a stored profile. If the torque rises abnormally fast or fails to reach the target, the system flags a cross‑thread error and rejects the assembly.
Yes. The feeding bowls, screwdriver bit, and nest are designed per your terminal sample. Quick‑change tooling allows changeover between different terminal families in under 20 minutes.
Missing screws are detected by either a screw presence sensor at the feeder or by the torque curve (no resistance). The machine will reject that cycle and optionally trigger an alarm.
Yes. For each assembly, the peak torque, final torque, and pass/fail status can be logged. Data is exportable via USB or directly to your MES via Ethernet (OPC UA/Modbus TCP).
