An electronic component mounting system mounts an electronic component on a substrate to manufacture a mounting substrate, and can prevent a mounting failure due to a positional error in a height direction of a substrate and ensure mounting quality. A print test device for testing the substrate after solder printing measures a height position of a height measurement point set on the upper surface of the substrateby a height measuring machineand outputs a measurement result as substrate height data. In a component placing step using an electronic component placing device, a control parameter for controlling a component placing operation of the placing headis updated. Accordingly, it is possible to correct a variation of the height position of an individual substrate and to prevent a mounting failure due to positional error in the height direction of the substrate.

Electric component mounting system and electric component mounting method

There is provided a screen printer capable of concurrently, efficiently subjecting a plurality of substrates, including different types of substrates, to printing operation. In a screen printerthat makes up an electronic component mounting lineand that prints electronic component bonding paste on a substrate, a substrate conveyance sectionthat conveys a substrateforwardly or backwardly in a direction of conveyance of a substrate is disposed at an intermediate position between a first screen printing sectionA and a second screen printing sectionB arranged symmetrically with respect to a center line CL. It thereby becomes possible to adopt a variety of substrate conveyance forms, as required, such as return conveyance for returning the substratefrom a downstream machine to an upstream side of the screen printerand bypass conveyance for letting the substrate sent from an upstream side pass through the screen printer, to thus be conveyed to a downstream machine. The plurality of substrates, including different types of substrates, can concurrently, efficiently undergo printing operation.

Electronic component installation apparatus

In an electronic component mounting method, a camera transporting mechanism transports a camera to a component supplying unit to take an image of a component. Thereafter the camera is evacuated from an upper area of the component. The image taken by the camera is processed by a recognition processing unit to acquire a position of the component. A mounting head transporting mechanism positions the mounting head to the component based upon the recognition processing unit, and the component is picked up by the mounting head. Another camera transporting mechanism transports another camera over a board to take an image of the board. Thereafter, the camera is evacuated from an upper area of the board. The image taken of the board is processed by another recognition processing unit to determine a mounting position. The mounting head then positions the component on the board based upon the determined mounting position.

In this electronic component mounting apparatus, a mounting head is movably arranged between the electronic component supplying unit and the board holding unit. A first camera for taking an image of the board in the board holding unit and detecting an electronic component mounting position, and a second camera for taking images of the chips of the electronic component supplying unit are arranged in such a manner that the first camera and the second camera can be entered/evacuated as against the electronic component supplying unit. Therefore, the electronic component supplying unit and the board holding unit are defined as a range to be transported, and the mounting head, the first camera, and the second camera are relatively traveled in conjunction to each other, a loss-time in both the electronic component supplying unit and the board holding unit can be avoided, and tact time can be shortened to improve a work-efficiency.

A component mounter which picks up components from two or more tape feeders aligned in a component feeder carriage, and mounts them a board. Suction nozzles for vacuum-holding components are disposed on the transfer head at a predetermined basic pitch in the X direction (tape feeders alignment direction) to form a nozzle line. Two or more nozzle lines are aligned in the Y direction (perpendicular to the X direction). These suction nozzles pick up two or more components from the tape feeders simultaneously, enabling to reduce the space required for installing the mounter and making the mounter more compact. Increased feasibility of simultaneous pickup of several components also improves mounting efficiency.

An electronic components mounting device has a plurality of feeder bases attached with tape feeders thereon, and a guide rail and a cylinder for drawing each of the feeder bases independently to a position for replenishing electronic components. When an electronic component runs out of the storage, only the feeder base that is carrying the relevant tape feeder gone out of the stock is drawn to a place for parts replenishment; in the mean time, the mounting actions keep on going by making use of tape feeders attached on other feeder base. Machine stop times can be decreased with the mounting device.
