[0001]

The present invention relates to a component mounting machine,
The present invention relates to a component mounting method for a multi-panel printed circuit board including a plurality of same patterns provided on the same plane .

[0002]

2. Description of the Related Art In recent years, many types of multi-planar P-plates have a plurality of identical patterns, and it is possible to efficiently mount components on such a multi-planar P-plate with as little loss as possible. Is being sought.

As a mechanism of the mounting machine, as shown in FIG. 2, components to be supplied are arranged on a straight line in a component supply section 11 and have a degree of freedom only in the one-dimensional direction indicated by an arrow. ing. Then, the component supply unit 11 is moved so that the fixed mounting head 12 comes to a position where the component to be sucked can be sucked, and the mounting head 12 is placed on the XY table 13 on which the component sucked from the component supply unit 11 slides. It was configured to be mounted on the multi-faced P board 14 that was cut.

[0004] With the above-described configuration, it is necessary to minimize the movement of the component supply unit 11 in terms of reducing the mounting time when mounting the same P board. Also, in the case of the variable speed chip mounting machine, once the low speed mounting component is mounted on the P board, the bonding position shifts, and the high speed mounting cannot be performed again. Therefore, it is necessary to mount the high speed mounting component in order. is there.

Due to the above-mentioned restrictions, as shown in FIG. 2, in the conventional mounting method, the component supply unit 11 groups high-speed mounting components to low-speed mounting components and arranges them in order. Z1, Z of the supply unit 11
The component supply unit 11 moves in one direction from the high-speed component side end to the low-speed component side end in the order of high speed to low speed in the order of 2. Under such restrictions on the order of mounting components, the mounting head 12 sequentially picks up components from the component supply unit 11 and places the components on the multi-planar P-plate 14 as much as possible, as shown in FIG. The mounting order is such that the moving amount of the XY table 13 is reduced. Or, as shown in FIG. 4, under the above-described restrictions on the movement of the component supply unit 11,
In this case, the same steps of each pattern were repeated, and the steps were sequentially implemented.

[0006]

In such a conventional mounting method of the multi-faced P board 14, the XY distance up to the worst-case mounting point is required.
Since the relative movement distance of the table 13 may move from end to end over the entire area of the multi-faced P board 14,
In some cases, the amount of movement of the XY table 13 becomes large, resulting in a time loss and a limitation in reducing the mounting time.

An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a mounting method of a multi-panel P board that further reduces a mounting time loss.

[0008]

In order to achieve the above object, a first aspect of the present invention provides a component mounting method, comprising the steps of arranging fixed component holding means and components to be supplied to the component holding means in an array. In a component mounter provided with a component supply unit that moves and positions in the component arrangement direction so that the component holding unit can take out the component, and a table that moves and positions the printed circuit board at a position where the component holding unit mounts the component. A component mounting method for a multi-panel printed circuit board comprising a plurality of identical patterns provided on the same plane, wherein the component arrangement of the component supply unit is divided into speed groups having the same component mounting speed; A part arranging step of arranging the parts in a group arranged in order of speed, and the part arranging step
