Method for supplying electric element and mounting system for electric element

Abstract

A method of supplying suction nozzles with electric components supplied from feeders each of which is operable to feed the electric components to its component-supply portion and which are arranged in a direction intersecting a direction of feeding of the components, the suction nozzles being held by nozzle holders supported by a movable member and arranged in the direction arrangement of the feeders, the movable member being movable to permit each suction nozzle to hold the component by suction, wherein a distance between axes of adjacent ones of the selected suction nozzles in the direction of arrangement of the feeders is adjusted, and / or a component-supply position of each feeder at which the component is located after each feeding action of the feeder is adjusted, so that the selected suction nozzles are aligned with the components at the component-supply positions, and the selected suction nozzles are operated to simultaneously hold the components located at the component-supply positions. Also disclosed is an electric-component mounting system operable to practice the method and mount the electric components on a circuit substrate.

Description

[0001] This application is based on Japanese Patent Application No. 2001-287339 filed on September 20, 2001, the contents of which are incorporated herein by reference. technical field [0002] The present invention generally relates to a supply method of electrical components and an electrical component installation system for installing electrical components, and more particularly, relates to how to improve the component installation unit in the electrical component installation system to receive electrical components from the conveyor of the component supply device of the system. component accuracy. Background technique [0003] In an example of the electrical component installation system, a component supply device and a component installation device are provided, wherein the component supply device includes a plurality of conveyors, and each conveyor can transport a series of electrical components (usually electronic components), and the component installation The unit ...

AI Technical Summary

Problems solved by technology

In these systems, multiple suction nozzles of the component mounting device cannot be aimed at the component supply part of the corresponding conveyor at the same time, so the electrical components delivered to the component supply part cannot be received by each suction nozzle at the same time

In addition, due to the variation of the distance between the axes of adjacent suction nozzles and the variation of the distance between the component supply parts of adjacent conveyors, the position deviation of the suction nozzles relative to the component supply parts of the conveyor may occur. These distance changes may be caused by suction Caused by errors in the manufacturing and assembly of nozzles and conveyors

In this case, the electrical components supplied from the conveyor cannot be held by the suction nozzles, or the electrical components held by the suction nozzles cannot be accurately centered on the suction surface of each suction nozzle, resulting in the suction of the suction nozzles. Supported electrical components are unstable
