Our safety sensors sense entry and exit of fixtures to prevent operators from entering the machine when entering and exiting.When the board is moved in and out to the anchor point, the operator removes and places the board, the sensor detects that there are no foreign objects, and then sends the conveyor to the cutting position again.The machine's safety door is closed, so the operator's hand cannot enter the safety door areaIf the conveyor does not reach the anchor point, the operator is also prohibited from picking and placing the PCB.
