In modern manufacturing assembly, screw locking remains a critical yet often problematic process. Manual screwing is plagued by low efficiency, inconsistent quality, and high labor costs, while fully automatic machines may be over-invested for small-batch, multi-variant production. To address this dilemma, Dongguan Sudizhi Automation is proud to present our upgraded semi-automatic screw locking machine, a cost-effective solution that perfectly balances flexibility, speed, and precision for global manufacturers.

Core Product Features

Our semi-automatic screw locking machine integrates intelligent design and robust construction, delivering superior performance for diverse assembly needs:

1. High-Efficiency Automatic Feeding SystemAdopts advanced blowing/vacuum suction dual-mode feeding technology, ensuring stable and smooth screw supply. Eliminates time-consuming manual picking, aligning, and positioning; achieves 1–1.2 seconds per screw locking, boosting efficiency by 50–80% compared to manual work. Compatible with M1–M6 screws of various lengths and types.

2.Precise Torque Control & Quality AssuranceEquipped with a digital servo electric batch and high-sensitivity torque sensor, providing 0.01–25 N·m adjustable torque range with ±3% high precision. Real-time monitoring prevents over-tightening (damaging parts) and under-tightening (loose assembly), effectively eliminating slippage, floating, and missing locks.

3.User-Friendly & Flexible Operation

• Intuitive touch panel: Simple parameter setup (torque, speed, count); operators master within 10 minutes.
• Ergonomic lightweight handpiece: ~0.8 kg, reduces fatigue; one hand secures the product, the other operates.
• Compact & mobile design: Small footprint, easy to move between lines; ideal for flexible production.

• Stable & Durable ConstructionBuilt with industrial-grade aluminum alloy and high-strength steel components. Core parts (motor, sensor) use international brands (Panasonic, Mitsubishi) for 24-hour reliable operation. Low maintenance, with an average MTBF > 8,000 hours.

5.Intelligent Safety & MonitoringFeatures automatic fault alarm (jammed screws, missing material), anti-reverse lock, and emergency stop. Optional counting & data logging for production tracking and quality traceability.

Key Customer Pain Points Solved

Our machine directly addresses the most common challenges in manual and semi-automatic assembly:

Customer Pain Point	How Our Solves It
Low manual efficiency (3–5s/screw), high labor cost	Auto feeding cuts non-value time; 1s/screw; reduces 2–3 operators per line.
Inconsistent torque, high defect rate (2–5%)	Precise digital control lowers defects to <0.1%, cutting rework costs.
Operator fatigue, high turnover, training costs	Light, ergonomic design reduces fatigue; minimal training lowers turnover impact.
Screw contamination (oil, sweat) causing rust	No manual handling; clean, automated process protects parts.
Long changeover time for multi-product lines	Quick screw/parameter change (<1 min); ideal for small-batch, multi-model production.
High cost of fully automatic lines	50–70% lower investment than full-auto; faster ROI.
