The operation of the above taping device will be described below. First, the vibration source 4 of the component feeder 1 is operated to apply a slight vibration to the storage component P of the hopper 2. As a result, the storage component P is taken vertically into the component take-in tube 2c in the longitudinal direction, and the electronic component P moves downward by its own weight through the curved passage 3a. The electronic component P whose posture has been changed from vertical to nearly horizontal in this movement process is attracted to and attracted to the magnet 3c at the end of the passage and is held at the position of the component outlet 3b. (See FIG. 3).

The component pulling force due to the magnetic force of the magnet 3c is
Since the leading electronic component P is set to be larger than the force of its own weight to fall from the component outlet 3c, the electronic component P after the posture change is attracted to the magnet 3c without falling from the component outlet 3b. Adsorbed and held.

On the other hand, the embossed tape 14 intermittently moving on the tape guide 12 is inserted into the empty
b, the suction nozzle 11d of the component insertion machine 11 is moved downward by a predetermined stroke from the standby position while applying a negative pressure to the suction nozzle 11d of the component insertion machine 11 in the same state. Insert into hole 3e. As a result, the electronic component P held at the position of the component outlet 3b is pushed downward from the component outlet 3b while being sucked by the nozzle tip, and the electronic component P is suspended below the embossed tape 14. Is inserted into the empty concave portion 14a.
Since the magnet 12b is located immediately below the recess 14a, the electronic component P inserted into the recess 14a
It is drawn downward by the magnetic force of 2b and closely adheres to the bottom surface in the concave portion 14a (see FIG. 4).

After the component is inserted, the negative pressure acting on the suction nozzle 11d of the component insertion machine 11 is released, and the suction nozzle 11d is returned from the lowered position to the standby position. Since the electronic component P inserted into the concave portion 14a is in close contact with the bottom surface in the concave portion 14a by the magnetic force of the magnet 12b, even if the electronic component P does not separate from the lower end of the nozzle even when the negative pressure action is released. Thus, the suction nozzle 11d can be reliably separated from the electronic component P. In the course of raising the suction nozzle 11d, the succeeding electronic component P moves forward in the curved passage 3a by one component, and the leading electronic component P moves to the magnet 3c.
And is sucked and held again (see FIG. 5).

The lowering and raising of the suction nozzle 11d is repeated each time the empty concave portion 14a of the embossed tape 14 that moves intermittently comes directly below the component outlet 3b. P is inserted sequentially.

A cover tape 15 is thermocompression-bonded to the surface of the embossed tape 14 after the component is inserted by a tape fixing roller 13, and the embossed tape 14 after the cover tape is fixed is connected to a pulley (not shown) in accordance with the intermittent movement. It is wound up.

You can save time.

Moreover, the component feeder 1 and the embossed tape 1
4, the taping device can be disposed close to the intermittent movement line, so that the taping device can be made compact and a large space is not required for installation of the device.

Further, since the electronic component P inserted into the concave portion 14a of the embossed tape 14 is brought into close contact with the bottom surface in the concave portion 14a by the magnetic force of the magnet 12b, the electronic component P is maintained even when the negative pressure action is released. Even in a case where the electronic component P is not separated from the lower end of the nozzle, the suction nozzle 11d and the electronic component P are reliably separated from each other, and the electronic component P inserted into the concave portion 14a is removed.
Can be reliably prevented from being disturbed.

In the first embodiment, the electronic component P after the posture change is held at the component outlet 3b by the magnet 3c provided at the end of the passage, but FIG.
As shown in the figure, the air suction hole 3f is formed in the stopper wall at the end of the passage.
Is provided so that the electronic component P after the posture change is sucked and held by the negative pressure acting on the air suction hole 3f, or the component outlet 3b is opened and closed as shown in FIG. A shutter plate 3g is provided, and the shutter plate 3g is provided.
The electronic component P after the posture change may be held by g. When the latter shutter plate 3g is used, the shutter plate 3g in the closed state is opened at the timing when the suction nozzle 11d is inserted into the insertion hole 3e.
The shutter plate 3g in the open state may be closed at the timing when the suction nozzle 11d returns to the inside of the curved passage 3a.

Although the suction nozzle 11d has been exemplified as a tool for pushing out the electronic component P at the component outlet position, when the distance between the component outlet 3b and the upper end opening of the recess 14a of the embossed tape 14 is small, The same component insertion operation as described above can be performed with a simple rod having no suction function.

Further, an example has been described in which components are taken into the component take-in tube 2c by applying micro-vibration to the storage component P. However, a movable tube that can move up and down is arranged outside the component take-up tube 2c. By moving the movable tube up and down as appropriate,
The parts may be taken into the parts take-in tube 2c in the same manner.
