A predetermined interval is set such that the opening surface of the recess is VC so that it is located on the upper side, and its feed hole 28
The material is transferred intermittently by a pin that engages with the material. This town-burning body 29 is arranged approximately parallel to the tape-shaped electronic component series 23 at a predetermined distance of I/'1'', and
As shown in the figure, the second rail 30 is arranged between the pin wheels 25 and 26 as shown in FIG. 9, which shows a longitudinal section, and is transferred. Reference numeral 61 denotes a measurement terminal that contacts a pair of electrodes of a chip-shaped inductor to measure its electrical characteristics such as inductance, and as shown in FIG. It is arranged at the lower part of the chain 26 and is configured to move up and down in synchronization with the transfer of the electronic component chain 23. 3
Reference numeral 2 denotes a first chuck disposed at the bottom of the tape-shaped electronic component series 25 transferred by the first intermittent transfer device;
As shown in FIG. 0 and FIG. 11, when the chip-shaped inductor is transferred to the upper part of the inductor, it is moved upward and its collar is clamped by the clamping part 63.

Thereafter, the inductor is moved downward while holding the brim to separate the inductor from the adhesive tape, and is further moved laterally between the tape-like strip part series 23 and the combustible strip 29. In this way, the electronic component of the inductor separated from the adhesive tape is transferred forward one pitch. 34 is a second chuck disposed above the combustible strip 29 transferred by the second intermittent transfer device, and as shown in FIG.
When the chip-shaped inductor is transferred between the tape-shaped electronic component chain 23 and the combustible strip 29 by the chuck 62, it moves downward and the suction part 55 comes into contact with the outer surface of the flange to remove the inductor. Suction and hold. At this time, the first chuck 62 releases its hold on the inductor, and the second chuck 64 moves upward while holding the inductor. Then, it moves laterally to the upper part of the flexible band-like body 29 and further moves downward to accommodate the chip-shaped inductor in the recess 27 of the burnable band-like body 29 . At this time, the second
The chuck 34 releases its suction and moves upward. The combustible strip 29 in which the chip-shaped inductor is housed in the recess 27 is transferred forward one pitch. These first intermittent transfer zones d1. The second intermittent transfer device, the first chuck, and the second chuck are each driven by the drive shaft (not shown) in synchronization with each other. The inductor is measured at the same time as t4h and sent to CI, so if the measured value deviates from the specified value, the inductor is transferred to the upper part of the first chuck 32. The inductor ceases to operate as expected, and the inductor is affixed to adhesive tape and transported to the front nine feet.
Since the inductor that should originally be housed is not housed in the concave portion of the combustible strip 29, the OTm strip 29 is set so as not to be transferred forward. Note that if all the inductors of the tape-shaped electronic component series 23 are within the measured standard range, there is no need to add a measurement process to this device (therefore, there is no need to perform the above operation. (8. 36 is a tape-shaped cover sheet made of a transparent thin film such as plastic, which is wound around a support frame 37 that is rotatably attached to a support (not shown) above the device, and is pulled out through a guide roller 68. Hey, roller 39
A chip-shaped inductor is housed in the C recess 27 through the C recess 27 and is placed on the upper surface of the combustible strip 29 excluding the feed hole 28. The winding frame 37, rollers 5B, 59, etc. constitute a cover sheet feeding device. Reference numeral 40 denotes a heating body made of steel or the like, which is heated by the heater 40 attached to a column (not shown), and which is heated by the tape-shaped cover 7-

The cover sheet 36 is heated to melt it slightly.

It is attached to both four parts of the recessed part 27 of the combustible strip 29. In other words, the heating body 40 and the heater 41 constitute a cover sheet attachment lid. None, the cover sheet pasting device C is not necessarily limited to such a heating means, for example, both shoulders in the longitudinal direction of the cover sheet, both ends of the recess 27 of the burnable strip 29 It is also possible to use a method such as applying an adhesive and sticking the cover sheet 36 to the combustible strip 29 in which the chip-shaped inductor is housed in the recess. A chip-shaped electronic component assembly C is constructed as a final product, and the chip-shaped electronic component assembly configured in this way makes it easy to attach it to a printed wiring board. Therefore, it is wound up on a reel or stored in a storage box in the form of a cassette.In an assembly of chip-shaped electronic components configured in this way, the electrodes of the chip-shaped electronic components are located at the bottom. To attach the K to the printed wiring board, the upper part of the chip-shaped electronic component is clamped with a chuck or adsorbed, and the K is simply moved (/'1), making it extremely easy to attach.

Although the automatic manufacturing apparatus for a chip-shaped electronic component assembly according to the present invention is configured as described above, it is not necessarily limited to the configuration shown in J:, and various modifications are possible. For example, the tape-shaped electronic component series is not a book with the structure shown in Figures 2 to 4, but a double-sided adhesive tape is pasted on one side 9' of the tape member with a through hole formed in C1-1. However, if the chip-shaped electronic components are pasted at a predetermined interval λ on this adhesive door, or if the required thickness is required, simply adhesive without using a chip/material.
