BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component automatic loading apparatus used to automatically load a required number of surface mount type electronic components into an empty storage case.

As a case for accommodating surface-mounted electronic components, there is already a flat plate-shaped case main body, and an electronic component take-out opening opened in the thick surface of the case main body and an take-out port for the electronic component. From the inside of the case main body, the component storage groove that is continuous in the same spiral shape, and the side of the case main body and the inside of the component storage groove are provided in the case main body with an air hole for sending and discharging compressed air. Electrons used to send electronic components to the ejection port along the component storage groove by pressure-feeding air that is intermittently fed from the air holes into the component storage groove, and to individually supply the electronic components to the suction head from the ejection port. A storage case for parts has been proposed (Shokaihei 2-141386).

This electronic component storage case has a compact case body with a flat plate shape, and a plurality of electronic components can be aligned and accommodated in a spiral component storage groove provided inside the case body. , It is possible to send out electronic parts to the outlet only by intermittently sending the compressed air of the electronic parts into the inside of the storage groove from the air hole provided on the side surface of the case body, and from the outlet of the electronic parts to the suction head of the electronic parts. It is preferable because the electronic components can be reliably supplied by separating them one by one.

When the electronic parts are newly loaded or reloaded into the storage case, the electronic parts are not damaged, and a large number of electronic parts are loaded, so that the electronic parts can be loaded smoothly mechanically and efficiently. Is desired.

Conventionally, as in the case described above, a storage case is used in which spiral grooves for aligning electronic components are formed in the case body, and the storage case is mounted on a vibrator, so that the case body of the storage case has a predetermined size. It has been proposed that a vibration is applied in the direction, and the vibration causes the electronic component to be housed in a concave groove inside the case or taken out from the concave groove to the outside of the case (JP-A-61-2395).

In loading the electronic component into the storage case, the component supply tube or chute is directly connected to the mouth end of the component inlet / outlet by a connecting member, and the electronic component is sent from the supply tube or chute to the component inlet / outlet of the storage case. Means is provided for loading the electronic component into the concave groove portion from the component inlet / outlet by the vibration applied to the storage case.

As a device for sending out electronic parts through the supply tube or chute, a so-called "ball feeder" for sending electronic parts by vibration along a part feed guide rail continuous from the lower side to the upper side in a spiral shape, It is conceivable to apply a parts feeder such as a so-called "multi-feeder" that aligns and feeds electronic components along a straight path.

However, since this loading means requires two different vibrating bodies on the parts feeder side and the storage case side, it becomes mechanically complicated, and if the vibrating modes of both are different, the supply tube or chute is connected. Due to the different vibration modes acting on the parts, the electronic parts are stagnant near the entrance and exit of the storage case, which hinders smooth feeding from the supply tube or chute to the entrance and exit of the storage case.
