Field of the Invention The present invention uses an electronic part storage case in which a plurality of surface mount type electronic parts are aligned and loaded, and mounts the electronic parts mounted in the storage case on a printed circuit board. The present invention relates to an automatic feeder for electronic components applied as a means for individually feeding to a head.

[0002]

2. Description of the Related Art Conventionally, an automatic supply device for electronic parts of this type has a flat plate-shaped case body in which a storage groove for electronic parts is continuously formed in a spiral shape. Uses a storage case for electronic components with multiple electronic components lined up and mounted, and the storage case is fitted and locked by a support frame on the machine side to stand up on the base and air provided on the side of the case. Air is sent from the holes to the inside of the housing groove intermittently to move the electronic parts along the housing groove, and the electronic parts are continuously positioned from the outermost circumference of the housing groove and opened on the thick surface of the case body. It has already been proposed to supply electronic components individually to a mounting head by adsorbing them from the outlet of the electronic components at the tip of the nozzle.

In the electronic component automatic feeder,
There is a case in which an electronic component storage case is provided in which an electronic component outlet is provided on an upper plate thickness surface of a case body, and an electronic component storage case is provided with a shutter for opening and closing the electronic component outlet for each delivery of the electronic component. This shutter is attached to the upper side of the case main body by being pivotally supported on a substantially middle side, provided on the upper side plate thickness surface of the case main body, and assembled and arranged inside the concave groove. The shutter is provided with a closing piece that opens and closes the outlet of the electronic component so as to project downward from one end side, and it is equipped so that it will appear and disappear inside the outlet through a through hole that communicates with the storage groove from the shutter attachment position. Has been done.
Further, a compression spring is attached to the other end side of the support shaft so as to be interposed between the lower surface of the shutter and the concave groove surface of the case body. The compression spring is provided so as to urge and support the end portion side of the shutter so as to be displaceable by a spring through a support shaft so that the closing piece of the shutter is always projected inside the outlet.

On the side of the machine, on which the storage case for the electronic parts is erected on the base with a support frame, together with the mechanism for sending the compressed air for sending the compressed air for the electronic parts into the storage groove,
A push pin such as a solenoid for opening and closing the shutter is provided so as to move up and down above the case mounting position. The push-push pin is provided so as to open and close the shutter each time the pressure-feeding air is fed by being driven in synchronization with the pressure-feeding air feeding mechanism.

However, the above-mentioned shutter closes the electronic component outlet so that the electronic components loaded in the storage groove do not fall out from the outlet when the storage case is transported, and the electronic component is removed when the electronic component is supplied. It may be one that keeps the exit open all the time. In particular, a driving means such as a solenoid is required to open and close the shutter each time an electronic component is delivered, so that not only the mechanism becomes complicated, but also the mounting head for the electronic component sucks the electronic component. As a result, it is not preferable that another mechanism is provided in the peripheral portion that moves to the mounting position with respect to the printed circuit board, because it limits the moving range of the mounting head.

[0006]

SUMMARY OF THE INVENTION The present invention is mechanically simplified by removing an extra drive means disposed above the equipment position of a storage case, and is simple so that the movement range of the mounting head is not limited. It is an object of the present invention to provide an electronic component automatic supply device which is embodied by changing the structure.
