Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component storage case used for mounting a surface mount type electronic component, and an electronic component automatic supply device using the storage case.

2. Description of the Related Art Conventionally, a disk-shaped case body has been provided as a storage case for electronic components, and a spiral component storage groove for aligning and storing a plurality of electronic components is provided inside the case body, and the component storage There is known a case for storing electronic components in which the outermost peripheral end of the groove is located at the side of the case body and the component delivery port is located (Shokaisho 60-119799). This electronic component storage case is equipped with the case body lying on the side of a vibrating parts feeder, and the vibration of the parts feeder acts on the case body, so the electronic parts stored inside the component storage groove Is configured to be sent out from the parts delivery port.

However, in this storage case, since the component delivery port is formed at the outermost peripheral end located at the side of the case body in the component storage groove formed in a spiral shape, the electronic component is connected to the case body from the component delivery port. It will be sent out tangentially. Therefore, considering the electronic component receiving means equipped in the automatic electronic component supply device, the electronic component receiving means must be devised so that the electronic component can be received more stably than the tangential direction of the case body. I have to. Further, in order to send out the electronic parts, since a parts feeder by applying a vibration to the case body is applied, it is inevitable that the entire equipment becomes large.

In addition to the electronic component storage case described above, a large number of electronic components are stored in the cassette body in a loose state,
A bulk type storage cassette is known in which electronic components are individually separated and sent out from the cassette body (Japanese Patent Laid-Open No. 63-127600).

In this electronic component storage cassette, a storage chamber for storing a large number of electronic components in a loose state is provided inside the cassette body,
Each electronic component slides downward from the storage chamber by its own weight, and the electronic component alignment hole is formed by continuously inclining downward from the bottom of the storage chamber, and air is intermittently ejected along the alignment hole. Is provided so that the electronic components can be individually supplied separately from the component outlet opening at the end position of the alignment hole.

However, in this storage cassette, the electronic component outlet is located laterally at the lower side of the storage cassette, so when the mounting head descends toward the storage cassette outlet, the cassette body interferes with the downward movement of the mounting head. Becomes Therefore, it is equipped with a vacuum and a cradle that can be moved back and forth corresponding to the parts outlet of the storage cassette, and once the electronic parts are received from the storage cassette by a vacuum or a cradle, the mounting head can move up and down. It is necessary to take it forward by the minute and transfer it to the mounting head. In addition, since each component including the storage cassette is located on the upper side of the position where the mounting head moves downward toward the vacuum or the pedestal, etc., the range in which the mounting head can move in the XY direction and the printed circuit board are placed. The layout position of the XY table will be restricted.

When intermittently sent to 13a ... 13n, the electronic component swivels upward along the spiral grooves 13a ... 13n toward the upper side of the case main body 10, and the case main body 10 is accompanied by stopping the air supply. Make sure to re-lower it under the dead weight. When the compressed air is repeatedly and continuously fed from the couplings 35 and 36 at a predetermined interval in the relative direction, the compressed air is appropriately adjusted by each air pressure and reciprocally reciprocates, so that the electronic component is a case. Approximately half of the left and right sides of 10 are moved clockwise and counterclockwise, respectively, and a plurality of them are aligned in the linear component feed groove 130 one by one, and a predetermined number of them are aligned up to the component outlet 14.

As the electronic component moves to the component take-out port 14, the mounting head H moves downward, and the tip of the nozzle abuts the electronic component located at the head of the component take-out port 14 at the bottom dead center. Suck up. After that, the mounting head H immediately rises, and repeatedly carries out to mount the electronic component on the printed circuit board by carrying the electronic component to the mounting position of the printed circuit board. Since the case body 10 of the storage case 1 and the peripheral mechanism portion are not arranged in the locus range in which the mounting head H moves in the XY directions, the mounting head H ejects electronic components from the component outlet 14 of the case body 10 to the nozzle tip. It can be directly extracted. The locus along which the mounting head H moves to the mounting position of the electronic component can be freely set, and the arrangement position of the XY table on which the printed circuit board P is mounted is not restricted.

A hook claw 50 projecting into the opening is provided on one end side, and the middle abdomen is pivotally attached to the case board portion 11 by a stop pin 51, and the rear end side is connected to the case board portion 11 via the stop pin 51. It can be equipped so as to be supported eccentrically by a spring 52 interposed between the two. The shutter 5 has a push pin 6
By using a solenoid or the like having a resistance against the spring 52, the rear end side is stopped and the pin 51 is displaced as a fulcrum so that the component outlet 14
Can be opened with the hook 50. Also, by operating in synchronism with sending the compressed air from the air feed holes 15a ... 15n, (15a '... 15n') to the storage path 13, the electronic components are separated one by one to the component outlet 14. You can move.

EFFECTS OF THE INVENTION As described above, according to the electronic component storage case and the automatic electronic component supply device using the storage case according to the present invention, the electronic component is linear from the spiral component storage groove to the component outlet. It can be moved horizontally one after another in the feed groove, and the electronic head can be carried to the mounting position by directly picking out the electronic component from the nozzle of the mounting head from the component outlet, so not only the mounting efficiency of the electronic component can be improved, but also the mounting head. The entire device can be designed arbitrarily because there is no restriction on the locus of movement and the position of the XY table.
