The SMT Reject Conveyor significantly improves the efficiency and quality control capabilities of electronic manufacturing lines by integrating intelligent sorting and buffering functions. Its core advantages are as follows: Core functional advantages: 1. Intelligent Sorting and Quality Isolation By receiving NG signals from AOI/SPI inspection equipment via photoelectric sensors, the system automatically switches defective PCBs to the auxiliary track for transportation to the repair area, preventing defective products from entering critical processes such as reflow soldering. The interception rate can reach 99%23. Qualified products are directly transported to the next process via the main track, achieving fully automated quality diversion. 2. Efficient Dual-Track Parallel Caching The dual-track design supports simultaneous caching of multiple PCBs (typical capacity of 20 pieces). The main track is used for normal production flow, while the auxiliary track serves as an emergency caching zone. When the pick-and-place machine is at full capacity or downstream equipment malfunctions, the auxiliary track continues to receive PCBs, maintaining 50% production capacity and minimising downtime losses.
