Is supported in a non-fixed state at the lower end surface portion (15A).

Reference numerals (16A) and (16B) denote a replacement rail base and an empty replacement rail base that have linear guides (7A) and (7B), respectively, and are provided with a new component supply device (5) for replacing the component supply device (5).

 Hereinafter, the operation will be described in detail with reference to the drawings.

The rotation of the ball screw (12) causes the desired component supply device (5) to wait at the component removal position, and the components in the tape stored in the tape reel (14) are removed by the suction nozzle, and the rotary disk (4) The substrate is conveyed onto the substrate conveyed by the conveyors (2) and (3) by the rotation of the substrate and is mounted on a predetermined position of the substrate.

Next, the setup change operation of the component supply device (5) will be described.
As shown in FIG. 5, the operator linearly moves the linear guide (7) to the replacement rail base (16A) provided with the new component supply device (5) and the empty replacement rail base (16B) to the right. And the component supply table (6) on the current linear guide (7) is transferred onto the empty replacement rail base (16B). After the transfer is completed, the new component supply device (5) is moved to the linear guide (7). ) Transferred to above (see FIG. 6).

FIGS. 7 and 8 show another embodiment in which the component supply table (6) is divided into a main base (17) and a sub-base (18) to simplify the changeover of the component supply device (5). It is explained based on.

A desired number of component supply devices (5) are installed in a positioning state via respective locating pins (19) provided on the sub-base (18), and the sub-base (18) is provided on the linear guide bearing (8). The component supply device (5) is attached to the linear guide bearing (8) by being fixed by the sub-base fixing bolt (21) while being positioned by the locate pin (20) provided on the main base (17) provided. . That is, by preparing a large number of sub-bases (18) to which the component supply device (5) is attached, the operator can attach the sub-base (18) currently attached to the main base (17) to the fixing bolts (21). ) And remove it,
Just by fixing the new sub-base (18), the setup of the component supply device (5) can be easily changed.

(G) Effects of the Invention As described above, according to the first aspect of the present invention, the component supply table on which the component supply device is installed can be moved to realize high-speed component mounting, and the component supply table can be replaced on the linear guide. Can be performed quickly by sliding, so that the operation rate of component mounting does not need to be lowered. Moreover, since another replacement rail base is used, the apparatus itself can be reduced in size, and the work of replacing the component supply device from the component supply table can be performed safely.

In addition, since only the component supply table on which the component supply device group is mounted is replaced and the guide portion for moving the supply table is left as it is, the component supply is compared to the case where the guide portion is replaced all at once. To make it possible to perform the component mounting operation from the next component supply device group so that the operation rate of component mounting does not decrease during the replacement of the device group, prepare multiple Only a minimum number of large rail stands need to be prepared, which saves space in these storage locations and facilitates handling.

According to the second aspect of the present invention, the component supply table on which the component supply device is installed can be moved to realize high-speed component mounting, and the sub base can be attached to and detached from the main base provided on the component supply table. In addition, the replacement operation can be simplified, for example, the parts supply device group can be replaced collectively in a relatively lightweight state, and the batch replacement can be performed manually. In addition, if the sub-base on which the next component supply device group is installed is immediately mounted on the main base, the component supply device can be replaced without lowering the operation rate of component mounting.

Furthermore, if a plurality of sub-bases can be placed on the main base, even if one sub-base is detached, components can be supplied only with the component supply device on another sub-base, and the operating rate of component mounting Can be maintained.

In addition, since the sub-base is lightweight and requires little space, the operating rate of component mounting during replacement of the component supply unit group is lower than when the parts up to the guide that guides the movement of the component supply table are replaced at once. In order to be able to perform component mounting operations from the next component supply device group without lowering the number of units, it is only necessary to prepare a plurality of light sub-bases, which saves space in these storage locations and facilitates handling. Easy.

Further, it is not necessary to perform the replacement of the component supply device next to the movement of another component supply table, so that the component supply device can be safely performed.

According to the third aspect of the present invention, the component supply table on which the component supply device is erected is moved to realize high-speed component mounting, and the second mounting table having the linear guide on which the component supply table is mounted is provided. Since the component mounting device can be replaced by detaching from the first mounting table having the slide mechanism for driving the movement of the supply table, the operation rate of component mounting does not need to be reduced, and the slide mechanism can be replaced by a plurality of second mounting mechanisms. Can be shared on the mounting table.
