Description

Electronic component supply unit {UNIT FOR SUPPLYING ELECTRONIC PARTS}

The present invention relates to an electronic component supply unit, and more particularly, to supply electronic components constituting a predetermined unit to the component mounting device alternately, and to supply the electronic component corresponding to the spacing of the heads in the component mounting device. In addition, the present invention relates to an electronic component supply unit capable of stably mounting electronic components having various sizes and supplying them to a component mounting apparatus.

Typically, component shuttle devices are devices that supply semiconductor packages or other electronic components from trays to component mounting devices. Semiconductor packages or other electronic components are supplied with a variety of different types arranged on trays, and each tray is discharged one by one from the tray transfer device and disposed within the operating range of the component adsorption nozzle. The parts adsorption nozzles adsorb the parts on the shuttle block after the parts are adsorbed and moved. The shuttle block moves with the parts adsorbed to supply the parts mounting apparatus.

In the component shuttle device, the performance of the equipment depends on the operation efficiency of the component adsorption nozzles and the component shuttles, and various methods for efficiently operating the component shuttle devices have been devised. That is, the adsorption nozzles for picking up parts from the tray are all fixed at equal intervals on the support block, and thus the spacing between the adsorption nozzles cannot be changed. The same applies to the shuttle block. Therefore, when the size of the component is relatively large, it is not possible to adsorb the component with a narrowly spaced suction nozzle, in which case only two of the four suction nozzles are used to adsorb and deliver a small number of components. There is no problem. On the other hand, even in the case where the spacing of the suction nozzle or the shuttle block can be adjusted, there is a problem that the work is not easy because the spacing must be manually adjusted whenever the size of the component changes.
