The present invention relates to a stick supply apparatus for packing semiconductor parts, and more particularly, to a stick supply apparatus for packing semiconductor parts, in which a plurality of sticks for packing components can be stacked vertically on a stick feeder, To a slider in a horizontal plane, and at the same time, the supplied parts can be continuously supplied to a surface mounting machine, thereby enabling the parts to be supplied in a stable form.

In general, a surface mount machine refers to a device that picks up a component and mounts the component on a predetermined place on a predetermined printed circuit board at a high speed / high accuracy, and the high speed / This can only be realized when the line is fed at high speed / high accuracy.

The parts are supplied in the form of tape rolls, trays, sticks, etc., so that the parts feeder is also classified as a tape feeder, a tray feeder, and a stick feeder And the parts supplied with the stick feeder, that is, the stick type, have a wide variety of types. Therefore, the classification is classified according to the LEAD shape, and then classified according to the number of times of LEAD.

In addition, the stick feeder may include a portion that senses that the stick feeder has completely consumed the parts in the stick, a portion that allows the empty stick to be re-fed, a portion that feeds the portion where the surface mount is picked up, It consists of parts that pick up a part and detect it.

When the component is picked up at the pick-up point, the next component is transferred to the pick-up point again. The component is repeatedly carried out, When it is completely exhausted, the empty stick is replaced with a new stick and the parts supply is continued.

However, since the conventional stick feeding apparatus operated as described above has a problem in that the component guide configuration on the oblique descending part and the horizontal belt is difficult, there is a single type of parts in which the components from the stick are fed to the pick- It is applied only to a small number of parts, and therefore, when the parts to be supplied are changed, there arises a problem that the entire feeder must be changed or only a limited number of parts must be supplied.

In addition, while the IC type supplied to the stick package usually has a lead, the part in the stick is discharged from the stick by gravity, and therefore, the force is transmitted to the pickup point (PICKUP POINT) The supply failure may occur due to damage of the IC lead (LEAD) due to the interference between the pickup parts, and further, the pickup lead may be damaged due to interference with the pickup parts.                         

The drive source of the component supply has traditionally used a large number of vibrators, which causes the surface mount machine to have a low reliability in picking up the components, and also has a problem in that it is also poor in speed variation and conveyance reliability. On the other hand, The surface mounting apparatus is disadvantageous in that it is significantly deteriorated in comparison with a high-speed surface mounting apparatus.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a stabilizer for a type of supply part, It is possible to supply most of the supplied parts from a single device, and the part cover part is placed on the upper surface of the slanting chute which causes GRAVITY (free fall by gravity) It is possible to reduce defects and errors in the supply of ICs having leads in combination with eliminating the influence of gravity in the horizontal belt and to adopt the belt conveying method as described above, The lower reliability of transfer is to realize high speed / high speed parts supply by high speed motor drive / belt transfer method.

According to an aspect of the present invention, there is provided a slide fastener comprising: a plate-shaped stick packed in a slidable manner with a plurality of parts arranged therein; A component supply unit for continuously supplying components one by one from the stick stacked in a sloping state and replacing the stick according to a signal value of the stick sensor recognizing the empty stick; A component cover portion for supporting the component supplied from the component supply portion from the upper portion so as to mount the component on the horizontal belt through the stick; A component feeding unit for sequentially supplying the component to the pickup position by operating the horizontal belt in accordance with the sensed component sensor signal value of the component supplied from the stick of the component supply unit; And a control unit receiving the signal value output from the sensor and controlling the horizontal belt and the component supply unit of the component.

According to the above configuration, in the present invention, when the component discharged from the stick is blocked by the component cover portion in the sloping down portion, the component of the flat belt is transferred to the motor drive / belt conveying To the pick-up position, and when the component sensor detects the part, the belt conveyance is stopped.

When the surface mount unit is picked up by the final pick-up position, the component sensor senses it and resumes the belt feed operation. The parts fed by the horizontal belt through the component cover are fed back to the pick-up point by belt transfer.

Replacement of the stacked sticks is performed when the stick sensor detects that the parts in the stick have been exhausted, and the empty stick is removed by the operation of the component supply part and replaced with a new stick to restart the supply of the components to the slope descending part.
