Description

  The present invention relates to a component mounting apparatus that takes out a component stored in a tray supplied by a tray supply device by a mounting head, and transfers and mounts the component on a substrate.

  As a method for supplying a component such as a semiconductor chip in a component mounting apparatus, a method using a tray feeder is known. This tray feeder stores trays in which a plurality of components are stored in a flat shape, and supplies the components by sequentially pulling out the trays and moving them to a component supply position (see, for example, Patent Document 1). . In the component supply system using a tray, since a plurality of components are stored in a flat component storage area in a flat array, the tray pulled out from the tray feeder can be taken out by the mounting head of the component mounting mechanism. Must be located within. For this reason, in a component mounting apparatus that is a target of a component supply system using a tray, it is necessary to appropriately set the relationship between the tray transport position of the drawn tray and the stroke of the mounting head in the component mounting mechanism.

  By the way, in recent years, in order to cope with flexible production in the component mounting line, it is required to make the line versatile. For this reason, as the parts feeder for supplying parts, there is a demand for mounting compatibility in which the above-described tray feeder and the tape feeder for supplying the parts held on the tape can be properly used as necessary. However, in the conventional tray feeder, it is difficult to make the general-purpose component mounting apparatus have mounting compatibility with the tape feeder, and the types in which the tray feeder can be mounted as it is are limited.

  That is, in the tape feeder, the component take-out position by the mounting head is fixed to the front end portion of the feeder body, and the mounting head only needs to move to this component take-out position. Since it is necessary for the mounting head to move over the entire range of the stored tray, it is necessary to set the movement stroke of the mounting head larger than when the tape feeder is targeted. For this reason, in the conventional mounting line, individual support such as preparing a tray feeder compatible model in which the stroke of the mounting head is set long in advance is required in order to allow the tray feeder to be mounted. The mounting compatibility was impaired and it was against the demand for general equipment.

  Therefore, an object of the present invention is to provide a component mounting apparatus that can improve the mounting compatibility of the component supply apparatus and promote the generalization of equipment.
