Problems to be Solved by the Invention Japanese Patent Laid-Open No. 4-35097
Japanese Patent Application Laid-Open No. 61-160 describes an apparatus in which various types of parts are mounted by replacing nozzles, such as the apparatus described in
In some cases, the shortest mounting time cannot be obtained even if the method described in Japanese Patent Application Publication No. 999 is adopted. The reason is that, in the nozzle replacement type component mounting apparatus, the number of times of nozzle replacement is a main factor of work time delay, whereas the mounting order determination using only the size of the component as a parameter does not necessarily require the minimum number of times of nozzle replacement. It does not always bring. The present invention is intended to solve this problem and to provide a method for determining a mounting order that is more effective in reducing work time.

The movement of the component mounting apparatus 10 is as follows. First, the conveyor 13 carries the substrate 1 from one side and positions it at a predetermined position. An adhesive has already been applied to portions of the substrate 1 where components are to be mounted. Here, the pair of pulse motors 33 and 34 operates, and the beam 2
6 is given a movement in the Y direction. When the pulse motor 37 operates, the work head 38 is also given a movement in the X direction. In this way, the work head 38 is moved in the X and Y directions, and the vacuum suction nozzle 39 is positioned above a predetermined component supply device. The mounting head 38 lowers the vacuum suction nozzle 39 toward the selected component supply device and picks up the component. After the parts are picked up, the mounting head 38 is positioned on the camera 42, and the amount of displacement of the parts is measured.
The component is mounted on the board 1 after correcting the amount of movement in the XY directions and the angle in the seater direction based on the measurement results.

Next, a method of determining the order of component mounting will be described. First, a component group to be sucked is made to correspond to each of the suction nozzles used in the current work lot, and a group of components is created. The number of component groups corresponds to the number of suction nozzles. Then, the suction nozzles are compared with each other to determine the use priority. In the embodiment, there are categories of small nozzles and large nozzles. First, a high priority is given to the group of suction nozzles 39a belonging to the category of small nozzles. This is based on the same technical concept as described in JP-A-61-160999. Next, suction nozzles belonging to the same category are compared with each other,
The ranking is made based on appropriate parameters (for example, the number of mounting points assigned to the suction nozzle). After that, according to the order, the suction nozzle which comes in order is replaced with the component group in charge.
Until all the suction nozzles have been mounted, continue using the suction nozzle without interruption, and then replace it with the next-ranking suction nozzle. It is possible that a component assigned to one suction nozzle is arranged over a plurality of component supply stages, and in such a case, an optimization method is applied to those components to select a pickup order. Decide.
