The present invention relates to a stick supply device for supplying a component drawn from a stick containing an electronic component such as a semiconductor chip to a surface mounter for mounting the component on a printed circuit board and a stick feeding method using the same.

In general, a surface mounting device (SMD) is a device that picks up a plurality of components provided by a component supplyer and mounts them on a printed circuit board at which each component mounting portion is set. The parts feeder feeds the parts so that the pick-up device of the surface mount machine picks up the parts. The parts feeder is a tape roll type or tray according to the supplied type. It can be classified into tray type and stick type. Accordingly, the feeder is also classified into a tape feeder, a tray feeder, a stick feeder, and the like according to the type of parts to be supplied.

Here, the stick feeder is a part for transferring to the position where the pick-up device picks up the part so that it can be picked up, a part for detecting when the part is picked up, a part for detecting that the part in the stick is exhausted, and a part It consists of parts that allow you to remove the used empty stick and to supply a new stick.

The process of supplying the part by the stick feeder transfers the part to the pick-up position by the supply driving source, and repeats the process of transferring the next part to the pick-up position when the picking of the part is completed. Then, when all the parts in the stick are exhausted, the empty stick is replaced with a new stick to continue supplying the parts.

Here, the method of conveying the parts to the pick-up position includes the method of pushing the parts in the stick by the vibration of the parts conveying part, the method of supplying the parts by tilting the stick, which is installed at an angle, by the belt drive, and the tilting of the stick repeatedly (seesaw type). It is divided into the method of pushing the parts by the vibration of the parts transfer part.

In the conventional stick feeder, the parts to be supplied in the stick are placed on the supply path so that the leads face downwards and are picked up by the body of the parts to the surface mounter. In this case, due to the friction between the leads and the supply path, Since the supply is not smooth and the lead portion of the part is fragile, defects such as deformation of the lead occur.

In addition, the parts in the stick are discharged from the stick by self-gravity and transported to the Pickup Point. At this time, pickup miss occurs when picking up due to interference between adjacent parts. There is a problem that leads are damaged.

In addition, the driving source of the component supply has traditionally used a lot of vibrators, which are affected by the entire surface mounter, and the reliability of picking up parts is poor, and it is also vulnerable to transfer reliability. The components mounted on the standard feeders are disturbed to cause pick-up misses, or components mounted on the PCB are shaken to cause a bad mounting position.
