The SMT Board Loading and Unloading Machine is an automated device that integrates PCB board automatic feeding (loading) and collection (unloading) functions. It is widely used at the beginning and end of SMT production lines to achieve closed-loop PCB board transmission. Its core advantages include space savings, reduced manual intervention, and improved production line continuity. The following analysis covers structural design, operating modes, technical parameters, and selection criteria:
Modular Design
Board Feeding Unit: Utilises vacuum suction cups (for bare boards) or a board pusher mechanism (for boards with components), feeding boards layer by layer via a lifting platform. The suction cup assembly supports lateral adjustment to accommodate different board widths14.
Board Collection Unit: Equipped with a ball screw lifting mechanism and a material tray positioning system, it sorts PCBs based on NG/OK signals. The automatic material tray replacement time is approximately 30 seconds34.
Central Control: PLC + touchscreen human-machine interface, integrated with SMEMA signal interface to achieve full-line interconnection.
Dual-Mode Operation
Single-Board Mode: Vacuum suction cups directly attach to bare boards and transport them to the track (suitable for bare boards).
Dual-Board Mode: The pusher device in the turnover box pushes PCBs with components into the track (component height must be ≤10mm).
