The SMT Dual Rail PCB Reject Conveyor is a critical connecting device in electronic manufacturing production lines. It achieves efficient production scheduling and quality control through a dual-track parallel design and intelligent screening functions. Core Functions: Parallel Processing and Screening Diversion 1. Dual-Track Synchronous Operation Featuring an independently controlled dual-track structure, it can simultaneously transport two PCB boards, doubling production line efficiency. When the main track equipment (e.g., pick-and-place machine) is at full capacity, the backup track automatically activates diversion to prevent production interruptions. 2. Intelligent Screening Mechanism Integrated with photoelectric sensors and a software control system, it automatically diverts defective products based on inspection results (e.g., AOI/SPI data): Passed Products: Proceed along the main track to the next process (e.g., reflow soldering) Defective Products: Switch to the auxiliary track and transport to the repair station or re-inspection area Screening Logic: Receives instructions from upstream and downstream equipment via the SMEMA signal interface, and combines with the PASS button to switch between manual and automatic release modes.
