The Double Rail Conveyor with Lamp Holder is a key auxiliary device in SMT (Surface Mount Technology) production lines, primarily used to connect machines in different processes, transport PCB boards, and provide lighting and manual inspection stations. Lighting and Inspection Support The light stand integrates an LED lighting system, providing operators with adequate lighting for visual inspection of PCB soldering quality or component placement accuracy. Some models support process card slots for conveniently placing work instructions. Modular Conveying Structure Track Design: Utilises anodised aluminium profile tracks, with width adjustable via high-precision lead screws (range 50–300 mm) to ensure parallelism and anti-static requirements. Drive system: Stepper motors or dual stepper motors drive anti-static flat belts/chains, with adjustable speed (0–1500 mm/s) to accommodate different production line rhythms. Conveying direction: Supports bidirectional conveying from left to right or right to left, with a standard height of 900 ± 20 mm, and is compatible with SMEMA signal interfaces for equipment interconnection.
