Board positioning device and board positioning method
This invention provides a board positioning method where a stopper and so on are not required when positioning a printed board in an X direction. Servo motors of a board supplying conveyer portion and a board positioning portion are driven to start carrying of a board. When a first board detection sensor detects the board before timeout of a first timer which starts timekeeping together with the carrying of the board, second and third timers start timekeeping. The servo motor starts decelerating, decelerates to an arbitrary speed, and keeps a constant speed after timeout of the second timer. When a second board detection sensor detects the board before timeout of the third timer, the servo motor is controlled to decelerate and stop the board at an arbitrary position, and a board recognition camera takes an image of a positioning mark of the board stopping at the board positioning portion to recognize a position of the printed board. The CPU controls the servo motors based on a result of the recognition in manufacturing running.
