Benefits of technology

[0006] 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, a position where the suction nozzle lowers to pick the electronic component of the component feeding unit is shifted due to the connection tape or the dismount or mount of the component feeding unit, thereby causing an error in picking a component and reduction in a pickup rate.

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, a position where the suction nozzle lowers to pick the electronic component of the component feeding unit is shifted due to the connection tape or the dismount or mount of the component feeding unit, thereby causing an error in picking a component and reduction in a pickup rate.

Embodiment Construction

[0021] An electronic component mounting apparatus having an electronic component feeding device and an electronic component mounting apparatus body will be described with reference to the attached drawings. This electronic component mounting apparatus is a so-called multifunctional chip mounter, which can mount a variety of electronic components on a printed board P.

[0022]FIG. 1 is a plan view of the electronic component mounting apparatus. An electronic component mounting apparatus body 1 includes a base 2, a conveyer portion 3 extending in a lateral direction in a center of the base 2, and two component mounting portions 4 and two component feeding portions 5 each provided on the front (on a lower side of FIG. 1) and the rear (on an upper side of FIG. 1) of the base 2. Each of the component feeding portions 5 is detachably set with a plurality of component feeding units 6 as the electronic component feeding device, thereby forming the 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...
