Description

  The present invention relates to a connection structure for connecting ends of carrier tapes for electronic components that supply electronic components to an electronic component mounting apparatus.

  Conventionally, when electronic components are mounted on a circuit board, a carrier tape in which the electronic components are individually stored is used to continuously supply the components. As a basic form of this carrier tape, as shown in FIG. 3 (A), a storage section 22 is continuously drilled and formed at the same pitch on a thick paper tape 21 using the thickness. In some cases, the upper and lower surfaces are covered with a cover tape 23 and a bottom tape 24 to store electronic components in the storage portion 22 and sprocket holes 25 are arranged along the edge. In addition, as shown in FIG. 5B, the storage portion 27 is continuously formed in the thin plastic tape 26 by embossing so as to be recessed and formed at the same pitch, and the upper surface is covered with the cover tape 28 and the storage portion 27 is formed. In addition, an electronic component is housed and a sprocket hole 29 is arranged along the edge.

  These electronic component carrier tapes are wound on a reel by a certain amount, but when switching reels to continuously supply components to the mounting device at the same timing, the ends of each other must be connected. Is done. Conventionally, in order to connect two carrier tapes, for example, as shown in Patent Document 1 (particularly FIGS. 7 and 8), a metal clip has been used. In this metal clip, a plurality of through holes are formed in a thin metal plate piece of a predetermined length at the same pitch as a sprocket hole of a carrier tape, and locking teeth are formed at the peripheral edge of the through hole. .

  And when connecting two carrier tapes using this, the end part of each tape is cut into a predetermined shape with a dedicated cutter jig, and the sprocket corresponding to the locking tooth at the end part joined adjacently An operation of joining a metal clip to the joint so as to penetrate the hole, bending the locking teeth using a dedicated connecting jig, and caulking was necessary. Further, a joint tape is attached to the portion.

  However, the above work is very fine and laborious and requires a skilled worker. In addition, since various special jigs and metal clips are required, each of them has a corresponding price, which is a factor of high cost. In addition, when disposing of used carrier tape, it is necessary to remove the metal clip and dispose of it, and if it is still attached, it must be treated as industrial waste, and there is no way to reuse the tape. There wasn't.

  For this reason, as a configuration not using a metal clip, for example, in Patent Document 2, in the plastic carrier tape, the storage portion of the other carrier tape is placed from the top in the storage portion in which the electronic component of one carrier tape is not stored. As a method for fitting and connecting, Patent Document 3 proposes a method in which end portions of both carrier tapes are formed into specific shapes that can be fitted to each other.

  However, the means disclosed in Patent Document 2 can only be applied to a carrier tape in a form in which a plastic sheet is molded and the storage portion is recessed, and cannot be applied to the above-described paper tape. Furthermore, it is necessary to perform processing so that the sprocket hole portions do not overlap each other. Further, the means disclosed in Patent Document 3 requires that each end portion of the carrier tape to be connected be formed in a specific shape that can be fitted to each other, and it takes time to process the carrier tape.

  The present invention has been made to solve such a conventional problem, and an object of the present invention is to propose a connection structure in which the ends of two carrier tapes can be connected extremely easily.

  In order to solve the above-mentioned problems, the present invention is a connection structure for connecting electronic component carrier tapes to each other via a connection member, and includes one end portion and the other start end portion of two electronic component carrier tapes to be connected. Respectively, the cover tape is peeled off by a predetermined length, cut, the exposed one or more storage portions are emptied, and a plurality of connecting members are formed on the lower surface at the same pitch as each of the storage portions. The projecting portion is provided, and the projecting portion is fitted into the empty storage portion so that a connecting member is installed between the two carrier tapes.

  Moreover, the means of sticking a joint tape in the longitudinal direction so as to connect the cover tapes on the upper surfaces of the both carrier tapes to each other was adopted.

  Furthermore, the means of sticking the joint tape in the longitudinal direction of the lower surfaces of both carrier tapes was adopted.

  In addition, the carrier tape for electronic parts employs means in which a housing portion is formed by punching and forming a thick paper tape at the same pitch, and both upper and lower surfaces are covered with a cover tape and a bottom tape.

  On the other hand, it is a connection structure for connecting empty electronic component carrier tapes before storing electronic components in each storage section via a connecting member, and at one end portion and the other start end portion of two carrier tapes The projecting portion is connected to the end portion and the start end portion so that a connecting member having a predetermined length provided on the lower surface with a plurality of projecting portions formed at the same pitch as the storage portions is laid between two carrier tapes. The means of fitting in each storage part was adopted.

  In this case, after the components are stored in each storage section, a means is adopted in which one end portion and the other start end portion of the two carrier tapes and the connection member are continuously covered and a cover tape is adhered.

  Further, in the above connection structure, means is adopted in which the connection member is obtained by cutting a carrier tape formed by embossing a plastic tape and continuously forming a storage portion at the same pitch into a predetermined length.

  In the connection structure of the present invention according to the above configuration, each protrusion is fitted into each empty storage portion so that a connection member is installed between the two carrier tapes. In this state, the carrier tapes can be connected reliably and firmly in a short time by a simple operation of press-fitting and fitting the connecting member.

  Moreover, if the joint tape is stuck in the longitudinal direction so as to connect the cover tapes on the upper surfaces of the two carrier tapes, the continuity of the cover tape can be ensured, and no trouble occurs during the mounting operation.

  Moreover, if a joint tape is affixed on the upper surface and lower surface of a connection part, respectively, it can connect more firmly, without a connection member dropping off.

  Further, even if the carrier tape to be connected is a thick paper tape that has a housing portion perforated, it can be connected with an extremely simple configuration without complicated processing of the end portion.

  On the other hand, even when empty electronic component carrier tapes before storing electronic components in each storage portion are connected to each other via a connecting member, similarly, empty storage at the end of each carrier tape is performed. The carrier tape can be securely and firmly connected to each other in a short time by a simple operation of press-fitting and fitting the connecting member into the portion.

  And after storing parts in each storage part, one end part and the other end part of the two carrier tapes and the connecting member are continuously covered and the cover tape is adhered, so that the cover tape is continuous and Become.

  Further, in the above connection structure, when the connection member is a carrier tape formed by embossing a plastic tape and continuously forming a storage portion at the same pitch, the connection member is used. Since existing plastic carrier tape can be diverted and used without preparing separately, it is economical and contributes to the reuse of resources.

  Hereinafter, preferred embodiments of a connecting structure for a carrier tape for electronic parts according to the present invention will be described with reference to the accompanying drawings. 1A and 1B are perspective views of a basic mode of the connection structure, in which FIG. 1A is an exploded perspective view of an entire configuration before connection, and FIG. 1B is a perspective view of a state after connection. FIG. 2 is also a partially cutaway side view, (A) shows an exploded view before connection, (B) shows a state after connection, and (C) shows a state where a joint tape is adhered. .

  In each figure, reference numeral 1 denotes a known carrier tape for electronic parts, and a storage part 3 which is continuous by punching through holes at the same pitch in a paper tape 2 having a thickness corresponding to the size of the electronic part to be stored. Is formed. 4, 4,... Are sprocket holes provided at the same pitch in the longitudinal direction of the tape 2 along the storage portion 3, and are used for tape feeding. Reference numeral 5 denotes a bottom tape adhered along the lower surface of the paper tape 2, which closes the bottom opening of the through hole to form the storage portions 3, 3,. Reference numeral 6 denotes a cover tape that closes the upper surface opening of the through hole, whereby electronic parts (not shown) are individually enclosed in the storage units 3, 3. The illustrated carrier tape 1 shows the end portion of the tape.

  On the other hand, 7 is another carrier tape to be newly used and has the same configuration as the carrier tape 1. That is, the paper tape 8 is provided with the storage portions 9, 9,... And the sprocket holes 10, 10, .., the bottom tape 11 is attached to the lower surface, and the cover tape 12 is attached to the upper surface, so that the storage portions 9, 9,. An electronic component (not shown) is accommodated. The illustrated one shows the starting end portion.

  Next, reference numeral 13 denotes a connecting member, which is obtained by embossing a plastic tape 14 and is used to connect the terminal end of the one carrier tape 1 and the starting end of the other carrier tape 7. It is. This connecting member 13 is formed by embossing a plastic tape 14 with protrusions 15, 15... Having the same pitch as that of the storage portions 3, 9 provided in the carrier tapes 1, 7. It is provided so as to project in the lower surface direction, and the outer shape of the projecting portions 15, 15... Has a shape that can be fitted as close as possible to the respective housing portions 3, 9. Reference numeral 16 denotes a sprocket hole provided at the same pitch as the sprocket holes 4 and 10 provided in the carrier tapes 1 and 7.

  Next, means for connecting the two carrier tapes 1 and 7 using the connecting member 13 will be described. First, the cover tapes 6 and 12 are peeled off by an appropriate length at the cut ends of the carrier tapes 1 and 7 and cut. Next, the electronic components are taken out from the storage units 3 and 9 whose upper surfaces are open, and are made empty. And the edge parts of both the carrier tapes 1 and 7 are made to oppose at predetermined intervals. At this time, it is important that the pitches of the storage portions 3 and 9 and the sprocket holes 4 and 10 of both carrier tapes are continuous at the same pitch in both of them (see each figure (A)). In this state, the connecting member 13 is bridged between the carrier tapes from above, and the projecting portions 15, 15... Are press-fitted and fitted into the storage portions 3, 9 (see arrows). As a result, the connecting member 13 is in a state in which the projecting portions 15, 15... Are closely fitted in the storage portions 3, 9 and are laid and fixed between the carrier tapes. Are firmly connected (see each figure (B)). At this time, the sprocket holes 4, 10, 16 are also in communication with each other. Therefore, the storage parts of both carrier tapes are in a continuous state at the same pitch, and are supplied to the mounting apparatus as they are.

  In this state, both the carrier tapes 1 and 7 are connected. In this case, since the connecting member 13 is only fitted, there is a possibility that the carrier tape 1 and the tape 7 may fall off due to an external force. Therefore, the joint tape 17 should just be affixed in a longitudinal direction so that all the both carrier tapes 1 and 7 and the connection member 13 may be covered as needed. Furthermore, in this case, since only the upper surface side of the tape is connected, the lower surface side may be lifted, and in order to prevent this, the joint tape 18 is also attached to the lower surface side (FIG. 2C). reference.). That is, after the connection member 13 is fitted and connected, the joint tapes 17 and 18 are affixed to both surfaces, so that the carrier tapes can be connected extremely firmly.

  In the present embodiment, the connecting member 13 having six projecting portions 15 is used, and the projecting portions 15 addressed to the two ends are fitted into the two storage portions 3 and 9 at the end portions of the carrier tapes 1 and 7, respectively. The two protrusions 15 in the middle are attached to each other, but the embodiment is not limited to this. That is, the number of protrusions of the connecting member is arbitrary as long as it is two or more, and accordingly, the number of storage parts that are emptied to fit the protrusions at each end of the carrier tape is also arbitrary. You can choose. For example, it is possible to use three projecting portions and three storing portions. Moreover, the space | interval of the edge parts of both carrier tapes is also arbitrary, and the state which floated one or more protrusion parts may be sufficient, and it is also possible to make it the state which joined the edge parts and did not have the protrusion part which floated. .

  Further, in the present embodiment, an example of connecting a carrier tape using a thick paper tape is disclosed, but the carrier tape in an embodiment in which a plastic tape is embossed has substantially the same configuration. It is possible to connect.

  Furthermore, in the above-described embodiment, the case where the components are already stored in the respective storage units at the mounting site and the carrier tape that supplies the components to the electronic component mounting apparatus is connected to each other has been described. The structure is not limited to that. That is, the present invention can also be applied to a state before components are stored in each storage section and a cover tape is pasted, that is, when a carrier tape without a cover tape and continuously provided with empty storage sections is connected. Is. For example, when storing electronic parts in each storage part of empty carrier tape, as in the above, empty carrier tape is wound around a reel by a certain amount, but a machine for individually storing parts When supplying this tape to the tape, it is necessary to connect the tapes to each other when exchanging the reels so as not to interrupt the work.

  As described above, the connection structure described above can be similarly applied when connecting an empty carrier tape in which no parts are stored. That is, by using the connecting member having the above-described configuration, the connecting member is bridged between the carrier tapes from above, and the protruding portion is press-fitted and fitted into each storage portion. The two carrier tapes are firmly connected to each other, and are laid and fixed between the two carrier tapes, so that the two carrier tapes are firmly connected. Then, after the components are stored in the storage units by the component storage machine, a cover tape may be attached to complete the carrier tape.

  As described above, according to the present invention, it is possible to connect both members easily and in a short time by simply press-fitting a connecting member having a simple structure between the end portions of the carrier tape. Furthermore, it can connect firmly by sticking a joint tape. Further, since a conventional metal clip is not used, a dedicated caulking jig or the like is not required, and it is not necessary to treat the used tape as industrial waste. Furthermore, since it can utilize for the connection of the carrier tape which consists of a thick paper tape, the kind of corresponding carrier tape expands and it is very versatile. Furthermore, since it can also be applied to connection of an empty carrier tape that does not store components, this is also highly versatile.

  Moreover, although the above-mentioned joining member 13 is obtained by embossing a plastic tape, as described above, conventionally, a carrier tape for electronic parts having the same structure has been used. That is, there is a plastic carrier tape in which the protruding portion functions as a storage portion (see FIG. 3B). Therefore, if the size and pitch of the storage portion and sprocket hole of this type of carrier tape match those of the paper carrier tape shown in the present embodiment, the plastic carrier tape is cut to an appropriate length. As such, it can be used as it is as a connection member in the present embodiment. That is, it is not necessary to prepare a connection member separately, and it is possible to divert existing plastic carrier tape waste and the like, which is very economical.
