Next, the stroke motor (115) is rotated through the interface (90), and the guide (1) is rotated through the ball screw (116) and the nut (117).
18), the variable stroke plate (113) is moved, and the moving body (56) is moved along the rail (110) via the upper and lower guide pieces (114) and the roller (112). In this way, the cam follower (127) provided on the moving body (56) is stopped at the position of FIG. 18 where the stroke calculated as described above is obtained.

Next, the index motor (175) is rotated, and the cam (119) is rotated to rotate the cam follower (1).
22), and the vertical swing lever (124) swings downward with the support shaft (125) as a fulcrum via the swing of the cam lever (121) and the link lever (123). Then, the tension of the tension spring (128) causes the moving body (56) and the rail (110) to descend while the roller (112) rolls along the upper and lower guide pieces (114), and the rail (11).
The lifting plate (55) integrated with 0) descends along the guide (54). Thus, the lifting block (53) descends,
The attachment nozzle (14) protruding from the mounting head (15) is lowered by the mounting body (25) and the shaft (24) via the cam followers (26) and (27) that have already transferred to the block (53) and the chip nozzle (14). The position (5) is lowered to the position of the upper surface by a distance "L-t1" from the position in FIG. 10, and the component (5) is sucked and taken out by vacuum suction from the suction port (108). After that, when the cam (119) further rotates, the swing lever (124) rotates counterclockwise in FIG. 6, and the nozzle (14) rises to the original position while adsorbing the component (5). .. In this position, the protrusion (57) is at the same height as the cylindrical cam (29).

Next, in the mounting head (15) on which the turntable (13) intermittently rotates to adsorb the component (5), the cam followers (26) and (27) roll along the cam (29), and At the stop station, the part (5) is taped (6)
3) Move without hitting etc.

The turntable (13) further intermittently rotates and the mounting head (15) reaches the component recognition station. During this time, the component suction operation of each step number is performed by the selected suction nozzle (14) of the mounting head (15) stopped in the suction station in the same manner as in the case of the step number "001" of the NC data.

At the recognition station, the recognition device (16) images the lower surface of the component (5) and performs recognition processing on the screen, whereby the displacement of the component (5) with respect to the suction nozzle (14) is recognized.

Next, the mounting head (15) is moved to the angle correction station, and the head rotation device (17) sets the correction angle of the rotation angle position based on the recognition result of the recognition device (16) to the θ angle data “θ1”. The rotating body (40) is rotated by the added rotation angle amount.

Next, the mounting head (15) reaches the mounting station by the rotation of the turntable (13).
During this intermittent rotation, the CPU (93) calculates the stroke to be lowered, and the stroke motor (115) is rotated to adjust the position of the moving body (56) to the stroke, as in the suction station. I shall. In this way, the mounting head (15) is operated in the same manner as in the suction station
Is lowered and the printed circuit board placed on the XY table (3) moved by correcting the recognition result of the recognition device (16) by rotating the X-axis motor (2) and the Y-axis motor (4). The component (5) sucked by the suction nozzle (14) at the θ angle “θ1” is mounted at the coordinate position (X1, Y1) in (6).

After that, the mounting operation of the chip component (5) is continued in the same manner, and when the step number of the NC data is completed, the turntable (13) is temporarily stopped and the printed circuit board (6) is ejected by an ejecting means (not shown). The next substrate (6) ejected from the XY table (3) is placed on the XY table (3). Then turntable (1
In 3), the intermittent rotation is started, and the mounting operation of the chip component (5) is started from the step number "001" of the NC data.

In this way, when the chip component (5) of the component supply device (8) with the reel number "103" runs out of components, the suction nozzle (14) does not suck the chip component (5), but the suction is performed. When the mistake is detected three times by the detecting means (not shown), the CPU (93) judges that the parts are out of order, suspends the automatic operation of mounting the parts, and the screen of the CRT (92) becomes as shown in FIG.

Next, the user replaces the component supply device (8) with the reel number "103".
When the tape (63) of "R3216TAI" is not provided and only the tape (63) of the embossed tape that supplies the same type of chip component (4) is present, the component supply device (8) loaded with the tape (63) The reel number "103"
Install in the position. In this case, since the tape type is different, the component ID of the reel number "103" of the part data must be replaced with that of the tape (63), but the component ID corresponding to the tape (63) has not been created. The supply tape type data is set according to the following procedure.

First, on the screen shown in FIG. 19, "submenu" is displayed.
Key (This is the part on the screen that is surrounded by a double frame and inside is displayed as "submenu". Below, all keys on the screen are surrounded by a double frame and the display is in that 21) to bring up the screen shown in FIG. 20, and when the "production model data correction / teaching" key is pushed, the screen shown in FIG. 21 appears. When the "part placement data" key is pressed on the screen, the screen shown in FIG. 22 is displayed in which the part ID is displayed for each reel number indicated by "R-NO", and the cursor key (12
9) The reel number “103” surrounded by a frame is selected using (131).

Next, when the "data edit" key is pressed, the screen shown in FIG. 23 is displayed, and the key labeled "type" surrounded by the double frame below "parts supply data" is pressed. As a result, the screen shown in FIG. 24 is displayed. Supply tape type data is set on this screen.

Since the tape type is embossed tape,
Press the key (131) labeled "Emboss" and press RN
When the screen of FIG. 25 in which the type of O is displayed as “emboss” is displayed and the “SET” key is pressed, the reel number “1
The supply tape type data memory “102” of “03” stores the supply tape type data of “emboss” as shown in FIG. 26, and the reel number “10” of FIG.
In the part surrounded by the frame "3", what was white before the setting changed to red, making it easy to see that the tape type data different from the "tape type" in the parts library data is set. ing.

Next, when the operator presses the "screen return" key in FIG. 25, the screen returns to the screen in FIG. 23, and by pressing the "screen return" keys one after another, the screen returns to the screen in FIG. The automatic operation is restarted by pressing the "production operation (installation)" key and then pressing the start key (97). If the mounting of the chip component (5) has been completed up to the step number “020” of the NC data of FIG. 14, the mounting operation of the step number “021” is restarted, but the chip component (5 of the step number “035” will be performed later. ) Is picked up, the component feeding device (8) attached to the reel number “103” moves to the component picking position in the same manner as described above, and the mounting head is moved to the picking station by intermittent rotation of the turntable (13). When (15) is reached, the tape is fed, and the setting operation of the descending stroke of the mounting head is performed as described below.

That is, first, the CPU (93) determines NC in FIG.
The reel number of the data step number "035" is "10.
3 ”from the data memory (102).
“Emboss”, which is the supplied tape type data, is read. The CPU (93) has the tape type "embossed".
The descending amount “L” is calculated using the calculation formula in the case of.

Next, the stroke motor (115) is rotated through the interface (90), and the guide (1) is rotated through the ball screw (116) and the nut (117).
18), the variable stroke plate (113) is moved, and the moving body (56) is moved along the rail (110) via the upper and lower guide pieces (114) and the roller (112). In this way, the cam follower (127) provided on the moving body (56) is stopped at the position of FIG. 19 where the stroke becomes longer than when the “tape type” calculated as described above is “paper”.

Then, as the cam (119) is rotated by the rotation of the index motor (175), the elevating block (53) is lowered as described above, and the suction nozzle (14) protruding from the mounting head (15) is removed. The distance "L" is lowered from the position of FIG. 12 to the position of the upper surface of the chip part (5) which is the position of the chute surface (88) and the part (5) is sucked into the suction port (10
8) It is adsorbed by vacuum suction from 8) and taken out, and it is moved up to its original position. After that, chip parts (5) as above
The mounting operation is performed and the automatic operation is continued. afterwards,
The original component supply device (8) with reel number “103”
When it is returned to that of 3216 TAI, press the "SET" key as the screen corresponding to FIG. 23 in which the reel number "103" is displayed in red and "Emboss" is displayed in the same manner as described above. , Display the screen in Figure 25,
Press the key labeled "Paper." By doing this,
The screen of FIG. 24 is displayed, and the supplied tape type data memory (10
“Paper” is stored in 2) as shown in FIG. In the screen of FIG. 24, the part of the reel number “103” is white indicating that it is according to the parts library data.

In the present embodiment, the case where the amount of lowering of the suction nozzle (14) at the time of sucking the chip component (5) changes depending on the difference between the two types of tape, paper and embossing, has been described. In addition to this, there is an adhesive tape in which chip parts (5) are adhered at a predetermined pitch on an adhesive tape, and further arranged along a chute in a loose state by a parts supply device (8) called a bulk cassette feeder. The chip component (5) thus cut may be supplied to the component suction position. As shown in FIG. 24, even when the formula for calculating the lifting stroke at the time of sucking the chip component (5) of the mounting head (15) in such a case is different, each tape type can be set and the component ID can be set. I try not to change it.

Further, as shown in FIG. 27, the upper surface of the chip component (5) on the embossed tape is the chute surface (88).
There may be a gap below that. In such a case, increase the number of "Emboss" keys on the screen of FIG. 24 so that one has no gap and the other has a gap, or separately from the supplied tape type data. This gap may be set as offset data for each reel number so that it can be stored in a predetermined area in the RAM (95).

Further, in this embodiment, a paper tape (63)
In this case, the component ID is set only in the case of, but even if the component ID is also set on the embossed tape (63), the reel number for which the paper component ID is set is the supply tape type. Embossed tape may be supported by setting the data. However, even if the component IDs increase even though they are the same chip component, it is difficult to manage them.
This can be done when it is desired to suppress D by a small amount and to change the tape type by using the supplied tape type data. When only one tape type is used at any one time and the component supply device (8) of another tape type is used urgently, it is effective to have only one component ID.

Further, instead of setting the tape type as in this embodiment, the difference with respect to the descending stroke designated by the component ID may be set again.

Furthermore, in this embodiment, when the parts data is set, the same data as the "tape type" of the parts library data is automatically stored in the data memory (102).
However, the downward stroke is calculated based on the "tape type" data of the parts library data, not normally in the data memory (102). Only when the supply tape type data is set using, the data may be read from the data memory (102) and the descending stroke may be calculated thereafter. At this time, the data memory (1
02) or the "tape type" data of the parts library data may be provided on the screen or the like so that the key can be switched.

[0086]

As described above, according to the present invention, even when the component supply device for the component type for which the data of the supply form corresponding to the component type is not created is used, the data of the supply form is provided for each arrangement position. Since it can be set, automatic operation of component mounting can be continued without the user's trouble.
