Embodiment Construction
[0031] figure 1 The pressure generating device shown is suitable for a parts transfer device that transfers and supplies parts such as semiconductor chips from a parts supply part formed by a bulk feeder to a mounting substrate not shown in the figure, and positions the parts by supplying negative pressure air to the parts transfer device In the specified position, in order to take out the leading part to the outside. The pressure generating device is used to generate negative pressure.
[0032] exist figure 1 The part output port of the bulk feeder is shown in , and the parts W are arranged neatly along the guide rail 1 and transported. On the guide rail 1, an openable shutter 2 freely reciprocating in a linear direction as shown by an arrow is provided, and the component outlet 3 is opened and closed by the shutter 2. As shown in FIG. In the state where the component output port 3 is opened by the shutter 2, after the suction tool 4 installed on the delivery head (not sho...
