Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is mainly used in electronic component mounting machines that mount electronic components, such as chip resistors and chip multilayer capacitors, onto substrates constituting electronic circuits. The present invention relates to a tape-shaped parts assembly.

Conventional technology As an electronic component mounting machine, conventional ↑,
A device using a tape-shaped component assembly as shown in Japanese Patent No. 98 is known.

As shown in FIG. 5, the tape-like component assembly P has a large number of housing recesses 1 formed in a row at a predetermined pitch in the tape body a, and stores the electronic components C therein. It is configured to hold the electronic component C by pasting a seal tape d on its surface.

In the electronic component mounting machine, the tape-shaped component assembly P
is intermittently fed in one direction by a feeding device g, the sealing tape is peeled off and wound up by a tape peeling device 11, and the electronic component C housed in the storage recess 1 is sucked and taken out by a suction device i. It is configured to be attached to a predetermined position on the substrate j using this suction means i.

By the way, as a single structure of the tape-shaped holding book that holds the electronic components C in the tape-shaped component assembly P, the following has been conventionally used.

When the electronic component is small, a notch 2 is formed in the thick tape body 21 to form a recess for accommodating the electronic component, as shown in FIG.
2, a supporting tape 23 is attached to the back surface thereof, and a sealing tape 24 is attached to the front surface. In addition, in the case of extraordinary electronic parts, in order to provide the necessary strength, a tape body 3 is made of a synthetic resin tape 32 with a housing recess 33 embossed thereon as shown in FIG.
1 with a sealing tape (not shown) attached to its surface. Furthermore, in recent years, one side is 20
~3 (There are cases where ultra-large electronic components of 1 mm or more are attached by automatic vc bonding. In that case, an opening 42 is formed in the tape body 41 as shown in the tjSS diagram, and the adhesive surface is exposed in this opening 42. In this case, an adhesive tape 43 is attached to the back surface, and an electronic component 44 formed on the opening 142 is held by the adhesive tape 43.

However, when the tape-shaped holder shown in FIG. 8 is wound up, the legs of the electronic component are deformed due to the bending of the tape body 41 in the part with a small radius of curvature. There was a risk that the product would get stuck or the adhesive would peel off, causing it to fall off during transportation. To deal with this, it is preferable to use a synthetic tape body 31 made of fat (as shown in FIG. There is a risk that the feed dog will easily become uncoupled and the feed will not be carried out reliably, and in order to avoid this, the radius of curvature of the feed device 8 portion must be increased, which will only increase the size of the device. There is a problem in that it cannot be used in common with other feeding devices for tape-like component assemblies.

The present invention aims to solve the above problems.

Means for Solving the Problems In order to achieve the above object, the present invention provides a tape-shaped parts assembly comprising a tape body having an embossed accommodation recess for accommodating the parts, and a sealing tape for closing the opening of the accommodation recess. The tape body is characterized in that slits or unevenness extending substantially perpendicularly to the longitudinal direction of the tape body are formed on the wall surface forming the accommodation recess of the tape body.

Function Since the present invention has the above-described configuration, the electronic component is held in the storage recess of the tape body, there is no risk that the legs of the electronic component will be deformed or fall off during transportation, and the feeding device part Since the wall surface forming the accommodation recess is easily bent by the slits or unevenness, it can be bent with a small radius of curvature, and a reliable feeding operation can be obtained.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to Figures Pt & 1 to 3.

In FIG. 1, a tape body 1 made of synthetic resin is embossed with a large number of accommodation recesses 2 arranged in a row at a predetermined pitch, and one side edge of the tape body 1 is provided with spout holes 3 at a predetermined pitch. Many are formed in a row. A plurality of slits 4 extending perpendicularly or substantially perpendicularly to the longitudinal direction of the tape body 1 are formed on the wall surface forming the accommodation recess 2.1. do.

As shown in FIG. 2, an electronic component 5 is housed in the accommodation recess 2 of the tape body 1, and a sealing tape 6 is pasted on the top surface of the tape body 1 so as to close the opening of the accommodation recess 2. A tape-shaped parts assembly 7 is constructed.

This tape-shaped component assembly 7 is placed into an electronic component mounting machine as shown in FIG. This electronic component mounting machine includes a feeding device 10 equipped with a toothed ring 11 that engages with the feeding hole 3, a tape peeling device 12 that winds up the sealing tape 6 at a distance of 211, and an electronic component in the housing recess 2. 5 is equipped with a suction pad 13 that picks up the printed circuit board 14 by suction and attaches it to a predetermined position on the printed circuit board 14. Further, a cutter 15 for cutting the tape body 1 after removing the electronic component 5 is disposed below the feeding device 10.

In the above configuration, the tape-shaped component assembly 7 has a feed v
It is intermittently moved one inch at a time in the direction of the arrow in FIG. 3 by the C unit 10. During the movement, first the tape peeling device 1
2, the sealing tape 6 is peeled off, and then the electronic component 5 in the accommodation recess 2 is picked up by the suction pad 13, and the suction pad 13 moves as shown by arrows 16, 17, and 18 in the figure to remove the printed circuit board. It is attached to 14. The tape body 1 from which the electronic parts 5 have been taken out is transferred to the IfT wheel 11 of the feeding device 10.
The tape-shaped parts assembly 7 is wound around the tape-shaped parts assembly 7, and at the same time, it is reversed and moved toward the cutter 15 along the guide 19, where it is cut and discarded.

When the tape body 1 passes through the gear wheel 1 of the feeding device 10, the wall surface forming the accommodation recess 2 is bent at the slit 4, and the tape body 1 can be bent with a small radius of curvature. As a result, the feed teeth of the gear wheel 11 and the feed hole 3 of the tape body 1 become disengaged, making it impossible to drive the tape, and the frictional resistance between the tape body 1 and the tape body 19 is large, making it difficult to move smoothly. There is no such fear.

In the above embodiment, slits 4 are provided on the wall surface forming the storage recess 2 of the tape body 1, but substantially the same effect can be obtained by forming unevenness 8 as shown in FIG. What can be obtained is obvious without needing a detailed explanation.

Effects of the Invention According to the tape-shaped electronic component assembly of the present invention, as described above, the unevenness or slit extending perpendicularly to the longitudinal direction of the tape body is formed on the wall surface forming the accommodation recess of the tape body. , the electronic component is held in the storage recess of the tape body, there is no risk that the legs of the electronic component will be deformed or fall off during transportation, and the wall surface that forms the storage recess with slits or unevenness in the feeding device part. is X'f
Because it bends easily, it can be bent with a small radius of curvature.
This has the effect of ensuring reliable feeding operation.
