NG/OK Unloader: Automates the unloading process for your dual-track production line by pushing PCBs out of a magazine onto the downstream machine’s conveyor. This unloader features automatic magazine alignment and pneumatic clamping for seamless operations.
Operational Principle
Based on signal recognition, the NG OK Unloader automatically segregates NG and OK boards into two separate lifting and turning boxes. You caonline with the AOI machine. After the AOI inspection, the detection of good (OK) and defective (NG) boards results in different signals.These signals are then transmitted to the NG/OK board unloader. The NG/OK board unloader receives the signals from the AOI machine for classification. It automatically stores PCBs in either the OK or NG bins. For instance, when the AOI outputs an OK signal, NG/OK board unloader will enter the mobile pusher car and directly move into the OK lifting and lowering car bin. On the other hand, when the AOI outputs an NG signal, our NG OK unloader will pass the PCBs to anther lane.
Features:
External Structure: The NG OK Unloader features a 3mm thick sheet metal and aluminum frame structure with a corrugated white surface coating.
Equipped with a Panasonic PLC control system for stable and reliable operation.
User-friendly touch screen interface with automatic fault diagnosis function for easy human-machine interaction.
Multiple audiovisual alarms and prompts on the touch screen for enhanced operational awareness.
Adjustable lifting step distances based on PCB thickness.
Automatic counting function for convenient production statistics.
Humanized design to prevent PCB breakage and improve output efficiency.
Motorized pusher for transferring PCBs into the receiving bin.
Stepper motor pusher with customizable force and speed settings on the touch screen.
Pusher device equipped with Omron groove-type sensors for dual-end limit protection to prevent PCB damage.
Pushing distance for PCBs is adjustable.
OK boards loaded into the front bin, while NG boards are transferred to the rear bin after processing.
Dual-line differentiation for NG and OK boards.
