DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component storage and supply magazine for storing a plurality of electronic components and supplying the electronic components for mounting the electronic components.

[0002]

2. Description of the Related Art In mounting electronic components on a circuit board, for example, a taping system shown in FIG. 14 is mainly used to facilitate handling of individual electronic components.

As shown in FIG. 14, a series of electronic components 1 based on a taping method includes a carrier tape 3 formed so that a plurality of cavities 2 are distributed in a length direction.
The bottom surface of the cavity 2 is closed by a bottom film 4 attached to the lower surface of the carrier tape 3. Each of the cavities 2 accommodates, for example, a chip-shaped electronic component 5. The upper surface of the cavity 2 is closed by a top film 6 attached to the upper surface of the carrier tape 3. Further, a plurality of feed holes 7 are provided in the carrier tape 3 so as to be distributed in the length direction.

The carrier tape 3 is replaced with, for example, an integral tape-shaped member formed by embossing the cavity 2 or a relatively thick plastic tape or the like in which a concave portion serving as the cavity 2 is formed. As a result, the bottom film 4 may be omitted.

In the case of supplying the electronic components 5 using such a series of electronic parts 1, the series of electronic parts 1 is fed in the longitudinal direction, and the top film 6 is peeled off at a predetermined position, whereby the cavity 2 is formed. Are sequentially opened, and the electronic component 5 is taken out from the cavity 2 in the opened state. The carrier tape 3 from which the electronic component 5 has been taken out is discarded together with the bottom film 4 while being cut into an appropriate length.

[0006]

However, the taping method described above has the following problems to be solved.

First, there is a problem that the work of loading the electronic component series 1 into the component mounting machine is very troublesome, and that automation is difficult. That is, the used carrier tape 3 and the bottom film 4 are removed, the used top film 6 is removed, and a new electronic component set 1 is set. , And set on a winding section to peel off the top film 6.

Further, the used carrier tape 3, bottom film 4 and top film 6 as described above are
Usually they cannot be reused and must be disposed of completely as garbage. That is, usually, the carrier tape 3 is made of paper or resin, and the bottom film 4 and the top film 6 are made of paper or plastic.
Further, the used carrier tape 3 is cut together with the bottom film 4 as described above.
Collected in a state where paper and plastic are mixed. Therefore, it is difficult to separate paper and plastic again and treat them, and they must be discarded as they are. In these respects, there is a problem that resources are wasted.

[0009] Further, the cutting of the used carrier tape 3 and the like described above may generate dust, which may have an undesirable effect on the circuit board and the component mounting machine.

[0010] The bottom film 4 and the top film 6 are bonded to the carrier tape 3 by thermocompression bonding, respectively. However, if the control of the pressure bonding conditions is insufficient, the bonding strength varies. If the adhesive strength is low, the bottom film 4 and / or the top film 6 may be peeled off from the carrier tape 3 during transportation, or conversely,
If the adhesive strength is too high, the top film 6 may be undesirably cut when the top film 6 is peeled off.

It is therefore an object of the present invention to provide an electronic component storage mode, more specifically, an electronic component storage and supply magazine which can solve the problems encountered in the taping method as described above. That is.

[0012]
