The supply table drive motor (9) is driven so that the tape feeder (7) moves to the suction position of the suction nozzle (13), and the tape feeder (7) is moved through the ball screw (10). Then, the supply table (6) is moved along the linear guide (11).

Next, in parallel with the above operation, the turntable (12) rotates intermittently, the mounting head (14) moves to the suction station, and the suction nozzle (13) stops at the component suction position. At the same time, the feed lever (46) swings downward by a vertical drive lever (not shown), and the feed pawl (4
5) meshes with the gear (44), and the gear (44) and the sprocket (42) rotate intermittently at a predetermined pitch. Thereby, the tape (40) in which the feed hole (41) meshes with the feed pin (43) is fed at a predetermined pitch.

The cover tape (52) peeled off with the release plate (51) as a fulcrum is wound around 3), and the chip component (4) is exposed and sent to the suction position of the suction nozzle (13).

Next, the suction nozzle (13) descends to suck and take out the chip component (4), and is moved to the next station by intermittent rotation of the next turntable (12). Then, the suction operation of the chip component (4) similar to the above is performed for the step number "002".

Thus, the step number "005"
The suction operation of the chip component (4) is performed for the chip component (4). The operation up to the mounting operation on the printed circuit board (5) after the suction of the chip component (4) having the step number “005” will be described.

When the suction nozzle (13) for picking up the chip component (4) reaches the recognition station, the component recognition device (15) recognizes the displacement of the component (4) with respect to the nozzle (13). Will be In the recognition operation, since the reel ID is “103”, the component ID is “R3216TAI”, and the packaging direction of this parts library data is “0 °”, the angular position deviation with respect to this packaging direction and X,
The displacement in the Y direction is recognized.

Thereafter, when the suction nozzle (13) reaches the angle correction station by the rotation of the turntable (12), the component recognition device (45 degrees) which is the mounting angle data of the step number "005" of the NC data is set. The suction nozzle (13) is rotated in the θ direction by the rotation angle amount in which the correction of the angular position shift recognized in 15) is added.

That is, first, the nozzle rotation motor (20) is rotated to move the nozzle rotation motor (20) through the vertically long hole (27) and the pin (28).
The nozzle rotating rod (26) is rotated to rotate the fitting part (34) to a position where the fitting part (34) fits into the fitting groove (36).

Next, the vertical lever (32) is lowered,

0) is rotated to rotate the angled suction nozzle (13) to which the above-described correction has been added, so that the chip component (4) is set at an angular position rotated 45 degrees from the packing direction. Thereafter, the vertical movement lever (32) is moved upward to return the nozzle rotating rod (26) to the position shown in FIG.

Next, when the turntable (12) rotates intermittently and the suction nozzle (13) reaches the mounting station, the chip part (4) moves to the position coordinates (X5, NC5) shown in the NC data of FIG. The X-axis motor (2) and Y
The rotation of the shaft motor (3) corrects the positional deviation recognized by the component recognition device (15), moves the XY table (1), and mounts the XY table (1) by lowering the suction nozzle (13).

The mounting operation of the chip component (4) having the step number "005" is completed in this manner, but the mounting operation of the chip component (4) is similarly performed in other step numbers.

For the step number "040", the component ID is "T143TH" from the tape feeder (7) having the reel number "106", and the chip component (4) stored in the tape (40) in the package shown in FIG. ) Is adsorbed by the suction nozzle (13), the deviation angle from the packing direction is recognized by the recognition device (15), and the angle for correcting the deviation angle is added to the mounting angle "90 degrees". The suction nozzle (13) is rotated by the device (16) and mounted on the printed circuit board (5).

Thereafter, the mounting operation of the chip part (4) is continued in the same manner, and when the step number of the NC data is completed, the turntable (12) is temporarily stopped, and the printed circuit board (5) is ejected by a discharging means (not shown). The next substrate (5) discharged from the XY table (1) is placed on the XY table (1). Then, turntable (1
In 2), the intermittent rotation is started, and the mounting operation of the chip component (4) is started from the step number "001" of the NC data.

As described above, when the chip component (4) with the reel number "103" is exhausted, the suction nozzle (1)
3), the chip component (4) is not sucked, but if a suction error is detected three times by detecting means (not shown), the CPU
(83) judges that the components have run out, suspends the automatic operation of component mounting, and the screen of the CRT (82) becomes as shown in FIG.

Next, the operator replaces the tape feeder (7) with the reel number "103".
If there is no “R3216TAI” tape (40) and only a bulk cassette feeder (8) for supplying the same kind of chip component (4), the bulk cassette feeder (8) is replaced with the reel number “103”. Attach in position. In this case, since the packaging direction is different, all the mounting angle data of the reel number "103" in the NC data must be changed according to the new packaging direction, and the packaging direction of the parts library data must also be changed. However, without doing so, supply direction offset data is set in the following procedure.

Next, when the "data edit" key is pressed, the screen shown in FIG. 19 is displayed, and the key "direction" surrounded by a double frame below "part supply data" is pressed. As a result, the screen shown in FIG. 20 is obtained. On this screen, supply direction offset data for correcting the angle of the difference in the packing direction is set. The packing direction is different from that of FIG. 5 by 90 degrees as shown in FIG. 7 (because it is a symmetrical part, it is the same in both clockwise and counterclockwise directions).
1 screen, and press the “SET” key.
The supply direction offset data is stored in the predetermined area of M (85) as shown in FIG. 22, and the portion surrounded by the frame of the reel number "103" in FIG. 21 is white before setting. Changes to red so that the offset data is set at a glance.

Next, when the operator presses the "Return to screen" key in FIG. 21, the screen returns to the screen in FIG. 19, and by pressing the "Return screen" key one after another, the screen returns to the screen in FIG. By pressing the "production operation (mounting)" key and then pressing the start key (87), the automatic operation is restarted. Assuming that the mounting of the chip component (4) has been completed up to the step number “008” of the NC data, the step number “0” is assumed.
09 is resumed from the mounting operation of step number “0”.
When the chip component (4) of "15" is sucked from the bulk cassette feeder (8) attached to the reel number "103", the chip component (4) is misaligned with respect to the suction nozzle (13) by the recognition device (15). Is recognized. In the recognition operation, the angle shift is the part ID “R3216TAI”.
Supply direction offset data "90"
The deviation angle from the angular position is recognized based on the angle obtained by adding the “degree”.

Next, when the suction nozzle (13) for sucking the chip component (4) reaches the angle correction station, the nozzle (13) is rotated in the θ direction in the same manner as described above. This rotation is performed under the control of the CPU (83) in accordance with the flowchart shown in FIG. 23 (the flowchart also applies to the above-described rotation). However, since the supply direction offset data is input, the suction nozzle ( 13), the θ swing angle, which is the angle for rotating “13”, is obtained by adding the mounting direction data “45 degrees” to the supply direction offset data “90”.
The angle obtained by adding the “degree” and the angle deviation recognized by the recognition device is calculated. If the angle is smaller than “360 degrees”, the motor (20) is rotated by the same angle as described above, and the suction nozzle (13) is rotated. ) To rotate.

Next, the suction nozzle (13) is attached to the mounting stage.
And the step number “01”
(X15, Y1) of the printed circuit board (5) shown in FIG.
The mounting of the chip component (4) is performed at the position (5).

Next, when the suction and mounting operations of the chip component (4) are continued and the tape feeder (7) of the reel number "106" runs out of components, the running out of components is detected in the same manner as described above and the automatic operation is stopped. Is done. The part ID "T143
If there is no tape (40) in the packaging style of "TH" and only the tape (40) in the packaging style of FIG. 12, the tape feeder (7) loaded with the tape (40) of the packaging style of FIG. At the position 106 ", the supply direction offset data is set in accordance with the packing direction as follows in the same procedure as described above.

That is, in the same manner as described above, a screen corresponding to FIG. 18 is displayed, and the reel number “106” is selected.
The user presses the "data edit" key to display a screen corresponding to FIG. 20, and presses the "direction" key. If the packing direction is "180
"Degree", so press the "180 degree" key
By pressing the key of, the RAM (85)
The supply direction offset data is stored as shown in FIG. Thereafter, the automatic operation is restarted in the same manner as described above.

Next, when the chip part (4) having the step number "040" is picked up, the recognition station (15) adds the supply direction offset data by the recognition device (15), and the packing direction of the parts library data is changed to " 180 degrees, and the angle correction station adds the supply direction offset data “180 degrees” to the mounting angle data “90 degrees”.
The angle is calculated by adding the correction amount of the angle shift by the recognition device (15) to "270 degrees" obtained by adding "degrees", and when the angle is smaller than "360 degrees", the angle suction nozzle as calculated is calculated. (13) is rotationally positioned and the mounting stay is
The mounting of the chip component (4) on the printed circuit board (5) is performed in the application. Thus, the step number “040”
The chip component (4) is mounted at the same position and in the same angular direction as in the case of the chip component (4) taken out from the tape (40) in the packaging form shown in FIG.

At step number "040" of the NC data of this embodiment, the mounting angle data is specified to be "180 degrees" instead of "90 degrees", and the packing form of FIG. Since the supply direction offset data is “180 degrees” when the angle is changed to “180 degrees”, assuming that the angle shift by the recognition device (15) is “0 degrees”, the θ swing angle becomes “180 degrees + 180 degrees = 360 degrees”. Since 360 degrees is equal to or greater than “360 degrees” which is the condition of the flowchart in FIG. 23, the θ swing angle is “360 degrees−3”.
60 ° = 0 ° ”, and the nozzle rotating device (16) does not rotate the suction nozzle (13). If the chip components (4) are sucked and mounted as they are, they are mounted on the printed circuit board (5) at a desired angle.

Further, in this embodiment, it has been described that no component ID is created for the case where the parts are supplied to the tape feeder (7) and the case where the parts are supplied to the bulk cassette feeder (8) in FIG. Even if a part ID has been created for each of which the data of the packing direction has been changed to a suitable one, when the tape feeder (7) is replaced with a different packing type, the stored contents of the part data of FIG. 9 are operated on the screen. It is not sufficient to change to the component ID of the replaced part ID, and the mounting angle data of the NC data must be changed for all the corresponding step numbers.
Therefore, it is effective to set the supply direction offset data as in this embodiment without changing the component ID. However, creating a different part ID only by changing the packing direction makes it complicated not only to create the part ID but also to manage and store it. It is effective to provide for each reel number.

Further, in this embodiment, the mounting angle data in the NC data is printed from the angular position (packing direction) when the chip component (4) is taken out from the tape feeder (7) or the bulk cassette feeder (8). The suction nozzle (1) is set to the angular position to be mounted on the substrate (5).
3) indicates a rotation angle to be rotated in the θ direction. Instead of the mounting angle data, the chip component (4) is used.
In the case where the data of the angular position at which the chip component (4) is mounted on the printed circuit board (5) with respect to the reference direction of the printed circuit board (5) is stored for each step number of the NC data, Suction nozzle (1
The angle to be rotated in the θ direction of 3) is calculated by the CPU (83) as the difference between the data on the packing direction as shown in FIG. 10 and the angular position at which the chip component (4) is mounted on the printed circuit board (5). In other words, if the supply direction offset data is set when the chip component (4) is replaced with a tape feeder (7) or a bulk cassette feeder (8) having the same kind and a different packing direction, the supply direction offset data is changed. If the set reel number is calculated by correcting the packing direction with the offset data, the chip component (4) can be mounted at an angular position at which the chip component (4) is mounted on the printed circuit board (5).

In this embodiment, the rotation of the suction nozzle (13) corrects the positional deviation by the recognition device (15) and rotates the mounting angle data. However, the mounting head is rotated by the intermittent rotation of the turntable (12). At a predetermined stop station between the suction station and the mounting station of (14), the chip components (4) sucked by the suction nozzle (13) form a pair to open and close and rotate in the θ direction. When the positioning is performed including the θ direction by gripping with the positioning claw, the claw is rotated by θ in accordance with the direction of the package shown in FIG.
The XY direction is determined, and the angle is rotated by the mounting angle θ in the closed state to perform the angle positioning. If the feed direction offset data is set when the feeder (7) or the bulk cassette feeder (8) is replaced, the reel orientation in which the feed direction offset data is set is adjusted to the direction corrected by the offset data in the packing direction. The positioning pawl is rotated and positioned, and the feeding direction offset data is added to the mounting angle as in FIG. 23, and the pawl is rotated by the calculated θ swing angle with the pawl closed to rotate. The angle position to be attached to (5) can be set.
