Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of creating mounting data for operating a component mounter for mounting components on a circuit board.

[0002]

2. Description of the Related Art Regarding the conventional method of creating mounting data,
This will be described with reference to FIGS.

In general, a component mounting machine, as shown in FIG. 7, has a mounting head 7 having a suction nozzle 2 for mounting a component on a substrate 1, and a substrate 1 arranged below the suction nozzle 2 for mounting the component on the substrate 1. It is provided with an XY table 3 to be moved to a position, and a component supply unit 5 in which a plurality of component supply means 4 for supplying components are detachably arranged in any order. The component is taken out from each component supply means 4 by the suction nozzle 2, and the component recognizing unit 6 recognizes the component during the transfer to the component mounting position to correct the position of the component and mount it at a predetermined position on the substrate 1. .

Next, a conventional method of deciding the mounting order of components and the arrangement of the component supply section 5 in such a component mounting machine will be described with reference to FIGS. 8 and 9. In FIG. 8, the components A and B to be mounted on the board 1 and their mounting loci are shown. FIG. 9 shows a flowchart of optimizing mounting data for determining the mounting order.

In FIG. 9, first, mounting position information of the board 1 (mounting position information of N1 to N6 shown in FIG. 8 (x ₁ , y
₁ , (θ ₁ ) to (x ₆ , y ₆ , θ ₆ )) are acquired (step # 21). Next, all the components mounted by the mounting machine are grouped by the mounting tact (component shape, component name) (step # 22). Next, from the group having the shortest mounting tact among the groupings in step # 22, the component closest to the substrate origin is sequentially ordered by N1 (N
Indicates the mounting order (block number); N1 indicates the first mounting), Z1 (Z indicates the arrangement order of the component supply means 4; Z1 indicates the first component in the component supply unit 5). (Indicating that the supply means 4 is set) is set (step # 23). Next, without changing the part, mount the part closest to the mounting position in the previous block number,
After that, mount the parts closest to the mounting point,
Continue until the parts are mounted (Step # 2)
4). Next, the component to be mounted next is searched for in order from the group closest to the component finally mounted in step # 24 and the group having the shortest mounting tact among the groupings in step # 22, and the component supply means 4 is set to the component supply means 4. It is set at the position next to the supply unit 5 (step # 25). The above steps # 24 and # 25 are repeated until there are no components to be mounted.

FIG. 10 shows mounting data created based on the flow chart of FIG. 9, and the component mounting locus based on the mounting data of FIG. 10 is shown by an arrow in FIG.

[0007]

However, in the above-described conventional configuration, there is a problem that some mounting tact losses occur in the mounting data for operating the component mounter.

Generally, in the component mounter, as a factor that determines the mounting tact, the movement range of the XY table 3, the rotation speed of the mounting head 7, the recognition time by the component recognition unit 6, and the movement distance of the component supply unit 5. Therefore, the tact with the slowest implementation tact among the respective factors must be implemented. Therefore, in the above-described conventional example, one component is determined by a certain grouping, the components are sequentially mounted, and the next component is mounted after the component is used up. The arrangement of the component supply means 4 is determined. Therefore,
In the above algorithm, the tact loss for the moving time of the component supply unit 5 is not considered, but when one component is scattered and distributed on the substrate 1, it exceeds the predetermined movement range of the XY table 3. Therefore, the mounting tact loss may occur.

In view of the above-mentioned conventional problems, the present invention minimizes the mounting tact loss even when some components are scattered on the board, and is based on the mounting database which is mounting know-how. As a result, the mounting time for producing one board as a whole can be minimized,
It is an object of the present invention to provide a mounting data creation method that enables efficient and efficient production.

The feature is that the implementation data is created so as to be shortened.

Preferably, for parts having two or more members, if the parts are distributed at distant positions, 1
