Electronic component mounting apparatus

摘要

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 (110) sends a feeding command to a component feeding unit feeding an electronic component belonging to a first step number, and drives a servomotor (28) and a drive motor (42) of the feeding unit to perform a component feeding operation and so on. After then, when the CPU (110) judges that the feeding unit is dismounted from the feeder base and mounted back thereon, the CPU drives a X axis drive motor (12 X) and a Y axis drive motor to move a board recognition camera (17) to the pickup position of the feeding unit (6), the camera (17) takes an image of a storage portion of a storage tape, and a recognition processing device (117) performs recognition processing to the image. A correction value based on this recognition result is stored in a RAM (111), the X axis drive motor (12 X) and the Y axis drive motor (12 Y) are driven taking this correction value into account, a vertical axis drive motor (16 A) is driven, and a suction nozzle (18) lowers and picks up the electronic component.
