Custom Auto-Soldering Machine for Piezoelectric Sensors

Toki Automation has engineered a high-throughput, customized auto-soldering solution specifically designed for high-precision piezoelectric sensor assembly. By integrating the industry-leading Hakko auto-soldering system, this machine bridges the gap between manual precision and high-volume industrial automation.

Key Technical Specifications

• High Capacity: Processes up to 200 piezoelectric sensors per cycle.
• Modular Loading: Utilizes 4 magazines; each holds 10 jigs (5 sensors per jig).
• Precision Soldering: Dual soldering checkpoints featuring the Hakko automated iron system.
• Quality Assurance: Integrated camera inspection and part detection for 100% fixture validation.
• Optimized Workflow: Efficiency Meets Precision

1. Ergonomic Briefcase-Style Loading

The system features a semi-automated workflow designed for operator ease. Sensors are loaded into jigs using a precision alignment template for wire positioning. These jigs are then housed in briefcase-style magazines, a design choice that ensures ergonomic handling and rapid machine loading/unloading.

2. Intelligent Jig Handling & Detection

Once the cycle initiates, the machine’s internal conveyor takes over. The system features smart magazine leveling:

• Partial Fill Detection: The machine automatically detects partially filled magazines and self-levels to fetch the next available jig.
• Automated Logistics: Sensors recognize empty loading points and full unloading points, ensuring a seamless, continuous cycle without manual intervention.

3. Advanced Vision Inspection & Validation

Before the soldering process begins, an integrated camera inspection system performs a comprehensive sweep. It validates that every slot is correctly filled and aligned. If a discrepancy is found, the operator is notified immediately, preventing wasted materials and soldering errors.

4. Precision Soldering with Hakko Technology

The heart of the machine is the Hakko auto-soldering system. At two dedicated checkpoints, the system:

• Automatically cleans the soldering tips to prevent flux buildup.
• Feeds solder wire at precise, pre-determined points.
• Ensures consistent thermal transfer for sensitive piezoelectric components.

5. Automated Cycle Completion

Post-soldering, jigs are automatically reloaded into the magazines. This "closed-loop" handling allows operators to remove finished batches and reload the next cycle with minimal downtime.
