2.4 The present invention relates to a taping component supply device, and in particular, a tape reel holding device that supports a tape reel and a guide device that holds the tape fed from the tape reel are provided separately, and only the guide device is fully equipped. Supply electronic components by placing them on a movable table device and shortening the moving distance for tape selection and positioning? The present invention relates to a feeding device for taping parts that increases the speed.

Figures 1 and 2 are supplying devices for mounting devices that form electronic circuits with lead wires (electronic components (hereinafter referred to as surface-mounted components)) fully attached to predetermined positions on circuit boards such as printed circuit boards or ceramic boards. The one shown in Fig. 2 is conventionally known. In this feeding device, there are many types of surface-mounted parts 1 that are mounted on the circuit board, and each of these surface-mounted parts 1 has many types. The tapes 2 are each wound around a tape reel 3, and the tape reels 3 are arranged in parallel on a reel holder 4 mounted on a movable table 5 and are rotatably supported.

The tape 2 is held between the guide base 6 and the guide plate 7, and is sent out by the n1 substrate 8 and transferred onto the circuit board 21 by the n1 mounting head 17, where it is surface-imposed. Since the mounting head 17 is set at a fixed position, in order to take out the required surface-mounted parts 1 and 2 from the tape 2, it is necessary to move the entire tape reel 3, etc. in a direction perpendicular to the feeding direction. In addition to the reel holder 4, the movable table 5 is equipped with the guide pace 6, guide grate 7, etc. In order to move at high speed over the entire width, a large amount of power is required, and the drive source requires large force and power.
It also has disadvantages that make it expensive, and also reduces the newness of the device.

That is, the tape 2 containing all the surface-mounted parts 1 is wound around the tape reel 3 as described above. The tape 2 is clearly shown in the figure and is formed from a paste tape forming a concave Wk in which the surface-mounted component 1 is stored, and an upper tape 16 and a lower tape attached to the top and bottom of this base tape. The tape reels 3 are arranged side by side in the reel holder 4 and supported so as to be rotatable n1 times.

The tape 2 is fed out by the rotation of the Chee Reel 3 sprocket 8 t''L1 The above distance between the guide pace 6 and the kite plate 7 is as planned, the guide plate 7
The upper teeth 16i are peeled off at the outlet end of the upper teeth 16i.

The upper tape 16 is wound with windings 11-14 and collected. Note that the take-up reel 14H% is pivotally mounted to a bracket 15 placed on the movable table 5. Upper tape 16
The surfaced part 1 in the tape 2 from which the tape 2 has been peeled off is attached to the suction nozzle 1 of the mounting head 17 provided above the sprocket 8.
It is adsorbed by 7a. The tape 2H of the surface-mounted part 1 is guided by the sprocket 8 and the guide roller 9,
l.It falls below the base 19 all the way through the notch 28 of the base 19 on the leg side.

As shown in FIG. 2, a bracket 27 and a motor 27 are placed on the base 19, and the bracket 27 has two guides extending in the axial direction of the reel holder 4 that supports the tape reel 3. A shaft 10 is attached, and a ball screw 13 is connected to the motor 26 in parallel with the guide shaft 10.On the lower side of the movable table 5, there is a ball bush 11 that slidably engages with the guide shaft 10, and a ball bush 11 that is slidably engaged with the guide shaft 10. Ball nuts 12 that are screwed onto screws 13 are respectively attached.

Therefore, by driving the motor 26, the movable table 5 is guided by the guide shaft 10 and moves in a direction perpendicular to the feeding direction of the tape 2.

On the other hand, the support stand 18 is placed on the base 19.
An XY table 20 is placed on top of the XY table 2.
0, a circuit board 21 is supported. The XY table 20 is moved in the feeding direction of the tape 2 and in a direction perpendicular thereto by a pulse motor 23 etc. supported on the base 19.

It is fed by the feeding device configured as above.

In order to mount all the surface-mounted components 1 on the circuit board 21, as described above, the surface-mounted components 1 are suctioned by the mounting head 17.
After adsorbing the The component 1 is mounted on the circuit board 21. Next, the mounting head 17 returns to its original position.
It is fed at a fixed pitch by sprocket 8 and picks up the next surfaced part.

In the meantime, the %XY table 20 (not shown) positions the υ circuit board 21 at a predetermined position using a control means.If the same surface-mounted parts 1 are to be mounted successively, the above steps may be repeated. When mounting a different surface-mounted component 1, it is necessary to transfer the surface-mounted component 1 to be mounted next below the mounting head 17.In this case, the motor 26 is rotated by the specified number of revolutions. Then, the movable table 5 is moved completely to position the desired tape reel 3 at a predetermined position.Therefore, the movable table 5 must be moved frequently over the entire width of the tape reel 3. If there are many types of attached parts 1 (and the total width of the tape reel 3 becomes wide), the moving distance of the moving table 5 becomes longer, and therefore the moving time becomes longer, resulting in a disadvantage that the efficiency of mounting the circuit board 210 is reduced. Furthermore, as mentioned above, the reel holder 4, tape reel 3, kite base 6, guide plate 7, etc. are placed on the movable table 5, making it large and heavy. It is necessary to move the movable table 5 at high speed, and for this purpose, the motor 26 must be large and have a high output, which has the disadvantage of being a high-power motor. Guide shaft 1 for high-speed movement

The tape reel 3 is held between the partition plates 4ai and the reel holder 4.
Since the tape reel 3 is supported by the side 0 G of the tape reel 3 and is wider than the tape 2 by the thickness of the plate 3, the pitch P is thicker than the pitch P1.

The tape 2 that has been fed out from the tape reel 3 is twisted 90 degrees by the groove B42 of the tape guide B30, is inserted into the groove A41 of the tape guide A29, is restored to its original state, and is inserted into the guide device 40. . Since the tape 2 is supported between the tape guide A 29 and the tape guide B 30, the tape 2 is smoothly fed even if the guide device 40 moves. The moving distance of the guide device 40 is a pitch P. It is shorter than the conventional one by an amount corresponding to the difference between P and pitch P. Also,
Mainly the guide device 40 is not placed on the movable table 5a (--this allows high-speed movement, and the drive source can also be made smaller and smaller in capacity.

It is inserted into the gap between the guide base 6 of 0 and the kite plate 7 and is locked to the n sprocket 8.

As described above, since the tape 2 is held between the tape guide A 29 and the tape guide B 30, it is smoothly fed from the wide reel holder 4 to the narrow guide device 40. Further, as described above, although the guide device 40 moves, the reel holder 4 does not (-) Therefore, the relative distance changes as the guide device 40 moves.Therefore, the tape 2 is fed out by that amount, and the reel holder 4 is not moved. When the device 40 returns to its original position, a barrel -LL is produced on the tape 2.

This barrel 2L tape guide A29 and tape guide B3
Since it occurs between 0 and 0, it is absorbed between this time and the guide device 40
This will affect the tape feed on the side.

, On the other hand, the moving distance of the movable table 5a is pitch P, which is 4 pitches P. The moving distance for selective positioning of tape 2 is much shorter than before, and therefore the time for positioning tape 2 is shortened, improving work efficiency. .

Furthermore, since the main component is the guide device 40 placed on the movable table 5a, the weight is lower than that of the conventional one.
The motor 26 of the movable table device 45 is therefore reduced.
It can be made completely compact and of small capacity.

In addition, since it moves lightweight objects, there is less wear on the sliding parts, which improves the durability of the device.

In the above embodiment, there are two tape guides, the tape guide A29 and the tape guide B30, but the present invention is not limited to this. Also, a movable table 5 is attached to the tape guide A29'.
