ものである。Detailed Description of the Invention (Industrial Application Field) The present invention provides a substrate transport device in a printed circuit board production line, in particular, a station for transporting a board, which adjusts the width of the transport station accurately and in a minimum time according to the width of the board. This article relates to a device that enables this.

送される。(Prior Art) In a conventional substrate transfer device, a transfer station includes a pair of stationary station guides that extend in a direction parallel to the substrate transfer direction and that face each other in the width direction of the substrate; The movable station guide is provided with a movable station guide that is movable in the width direction of the board between the two. It is moved by a drive mechanism consisting of a driving motor. Further, the screw is provided with a position detecting means for positioning by pulse detection or the like in order to perform position control. Then, the substrate is guided and transported between one stationary station guide and one movable station guide.

制御を行うことが困難になつていしまう。 By the way, the position control of the movable station guide is performed based on a signal from the position detection means.
When the rotational position detecting means reaches a predetermined signal value, the motor is controlled to stop, but due to inertia, an error occurs with respect to the desired stopping position. If the motor is rotated in forward and reverse directions over a long period of time, this error will accumulate, and the error between the signal obtained from the position detection means and the actual position of the movable station guide will gradually increase, making it difficult to determine the exact position. Control becomes difficult.

関わる時間が掛りすぎるという問題点があつた。(Problems to be Solved by the Invention) In the width determination control in the conventional substrate transfer device described above, regardless of the size of the substrate, the movable station guide returns to the origin position set on one of the fixed station guides. This is then carried out by moving the movable station guide to a position that matches the size of the substrate, which poses a problem in that it takes too much time to determine the width.
