Electronic component mounting apparatus

Abstract

This invention is directed to prevention of reduction of a pickup rate of an electronic component when a component feeding unit is dismounted from a feeder base and mounted back thereon. A CPU sends a feeding command to a component feeding unit feeding an electronic component belonging to a first step number, and drives a servomotor and a drive motor of the feeding unit to perform a component feeding operation and so on. After then, when the CPU judges that the feeding unit is dismounted from the feeder base and mounted back thereon, the CPU drives a X axis drive motor and a Y axis drive motor to move a board recognition camera to the pickup position of the feeding unit, the camera takes an image of a storage portion of a storage tape, and a recognition processing device performs recognition processing to the image. A correction value based on this recognition result is stored in a RAM, the X axis drive motor and the Y axis drive motor are driven taking this correction value into account, a vertical axis drive motor is driven, and a suction nozzle lowers and picks up the electronic component.

Description

CROSS-REFERENCE OF THE INVENTION [0001] This application is based on Japanese Patent Applications No. No. 2005-192116, the content of which is incorporated herein by reference in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates to an electronic component mounting apparatus having a plurality of component feeding units aligned on a feeder base, the component feeding unit feeding an electronic component stored in a storage tape to a component pickup position, in which a suction nozzle picks the electronic component fed by the component feeding unit and mounts the electronic component on a printed board. [0004] 2. Description of the Related Art [0005] In this kind of electronic component mounting apparatus, particularly in a high-speed gantry-type mounting device, since the component feeding units are fixed and not moved, there are rapidly increasing users employing the so-called splicing where storage tapes are connected to each o...

Problems solved by technology

However, in a case where the component feeding unit is dismounted from the feeder base, the storage tapes are connected to each other with a connection tape, and then the component feeding unit is mounted back on the feeder base when a shortage of electronic components occurs,
