Abstract: As component replacement positions where component feeding tables are replenished with components, are arranged a number of component replacement positions, the number being obtained by substituting a total number of component feeding tables into a specified function. A component feeding table that is not in a component suckup position is moved necessarily to any one of the component replacement positions regardless of the combination of component feeding tables. This component replacement position is determined through steps of setting sequence numbers on the component replacement positions by the specified function based on the distance from the component suckup position, setting sequence numbers and component-replacement direction on the plurality of component feeding tables by a specified function, and giving a specified function the sequence number and component-replacement direction of a component-exhausted component feeding table.

Abstract: This invention provides an electronic component sucking method in which the movement of a component supply table (15) can be increased without increasing tact time, thereby improving the mounting efficiency of electronic components (2, 4). According to this invention, the movement disabled period of the component supply table (15) is set on the basis of the height of an electronic component (2, 4) in order that the interlock time for a low electronic component (4) can be set to be shorter and the movement enabled period of the component supply table (15) can be set to be longer. Therefore, a low electronic component (4) can have a shorter tact time, thereby improving the overall mounting efficiency of electronic components.

Abstract: A board transfer unit for transferring a printed circuit board on which electronic components are mounted. The board transfer unit has sensors for detecting the length, width, and thickness of the board. The board weight is calculated based on the detected data from the sensors. The board transfer unit also receives information on types of components mounted on the board from a machine in the previous process. Optimal acceleration and deceleration rates are selected from previously prepared data based on the board weight and the types of components mounted in the previous process. Accordingly, the board transfer unit realizes the optimal board transfer corresponding to diversifying board weight and mounting conditions.
