Description

  The present invention relates to a transport packaging tape for stably and automatically supplying parts.

  Various electronic devices including portable devices are becoming thinner, smaller, and lighter. Various electronic components such as semiconductor packages mounted on these electronic devices are also required to be thin, small and light.

  In order to mount the electronic component on the circuit board, the electronic component is previously stored in a transport and packaging tape that can be automatically supplied and set in a feeder of the automatic mounting machine. The feeders on which the transport packaging tape is set are fixed to the automatic mounting machine, and are taken out from the transport packaging tape one by one by the suction nozzle of the automatic mounting machine and mounted on the circuit board. The transport and packaging tape includes a carrier tape in which a pocket for storing the electronic component is formed and a cover tape that covers the electronic component so that the electronic component does not fall or change its posture.

  In general, a cover tape is composed of a base material layer and an adhesive layer, and a transport wrapping tape is configured by melting a seal layer at both ends of the long side of the cover tape and bonding it to a carrier tape. In order for the suction nozzle of the automatic mounting machine to pick up the components, in the feeder, the operation of peeling the carrier tape and the cover tape and the operation of sending out the transport packaging tape are performed simultaneously so that the electronic components can be taken out. As for the timing of removing the cover tape, the cover tape is peeled off several to ten or more pockets before the pickup position, and waiting for the parts to be adsorbed. Therefore, there is nothing to hold the part until the part is picked up after the cover tape is peeled off, and the electronic part is conveyed to the pickup position in an unstable state. Electronic components may jump out of the pocket of the carrier tape due to vibration during transport by the feeder or when the cover tape is peeled off, or the posture may change in the pocket, which hinders continuous mounting on a stable circuit board. Yes.

As described above, as electronic devices become thinner, smaller, and lighter, electronic components are also becoming thinner, smaller, and lighter.
Along with this, in the electronic component mounting process on the circuit board, the electronic component jumps out of the pocket during transfer of the transport packaging tape due to the vibration of the automatic mounting machine and feeder, and the posture change in the pocket increases and stable component supply is possible. It's getting harder. The malfunction in the conventional transport packaging tape is demonstrated below using FIGS. 9-12.

FIG. 9 is a top view of a conventional transport packaging tape. A part 4 is accommodated in a pocket 3 of the carrier tape 2, and a cover tape 1 covers the part 4, and both sides of the pocket 3 are fixed by adhesive portions 8.
FIG. 10 is an image diagram of a conventional transport packaging tape. The mode that the cover tape 1 was peeled off using the cover tape 6 after peeling is represented.

  When the cover tape is peeled off, the posture is changed due to the parts 4 jumping out of the pockets 3 due to vibrations of the automatic mounting machine, feeder and the like. If the posture of the component changes greatly, the suction nozzle of the automatic mounting machine cannot suck the vicinity of the center of the component, and angle correction and X / Y correction by the automatic mounting machine become impossible. In addition, the suction nozzle may not be able to pick up parts.

  FIG. 11 is a cross-sectional view of a conventional transport packaging tape. When the cover tape 1 is peeled off, the posture of the component 4 is changed in the pocket 3. If the component 4 is inclined in the pocket 3 as described above, the suction nozzle cannot suck the component 4.

  FIG. 12 shows a state where the suction nozzle 11 of the automatic mounting machine is trying to suck the component 4 in the pocket 3 with respect to the conventional transport packaging tape shown in FIG. In the conventional transport packaging tape, when the cover tape 1 is peeled off, the posture of the component 4 is lost due to vibrations received by the transport packaging tape because it is an automatic mounting machine or fee. I couldn't. Further, the component 4 jumps out of the pocket 3, and the component 4 may be lost from the pocket 3 before the suction nozzle 11 enters the suction operation.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a transport packaging tape for stably mounting electronic components on a circuit board.
In addition, the above Patent Documents 1 and 2 are provided with two or more perforations or slits in the longitudinal direction of the cover tape, the purpose of which is to vary the adhesive force between the cover tape and the carrier tape. The cover tape can be peeled off without consideration.

The following means were used to solve the above problems.
When peeling the cover tape that composes the transport packaging tape from the carrier tape, the cover tape remains partly adhered to the carrier tape to prevent the electronic component from changing its position in the pocket of the carrier tape. .

By using the above means, the electronic component maintains its normal posture in the pocket of the carrier tape even if it receives vibration from an automatic mounting machine or feeder when the electronic component is mounted on a circuit board, etc. The suction nozzle of the mounting machine can stably pick up electronic components.
Further, the present invention is not limited to electronic parts, but can also be applied to supply of assembly parts such as screws or supply of food materials in a food manufacturing process.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a top view of a transport and packaging tape according to the first embodiment of the present invention.
The structure of the transport wrapping tape according to the present invention is such that the cover tape 1 is fixed to the surface of the carrier tape 2 with an adhesive portion 8 so that the part does not jump out of the carrier tape 2 with the pocket 3 for housing the part 4. Has the structure. The carrier tape 2 is formed with a positioning hole 5 for positioning during transportation, and the cover tape 1 is also formed with a hole 9 for aligning with the carrier tape 2.

  By aligning the positioning hole 5 of the carrier tape 2 and the positioning hole 9 of the cover tape, the component presser 7 formed on the cover tape 1 can be provided at a predetermined fixed position of the pocket 3 and can be overlapped with the component 4. The component presser 7 is a part of the cover tape 1 and is provided with a notch 12 around it so as to be easily separable. An adhesive portion 8 indicates an area where the carrier tape 2 and the cover tape 1 are bonded. In general, the bonding is performed by thermocompression bonding or an adhesive. The cover tape 1 has a structure in which an adhesive layer is laminated on a base material layer, and the adhesive layer adheres to the carrier tape 2, but the cut portion 12 is formed from the adhesive layer side toward the base material layer. An incision 12 is provided to reach the layer. And it is desirable that the cut | notch part 12 has reached 1/2 of the thickness of the base material layer. Therefore, in the cut portion 12, there is no adhesive layer between the carrier tape 2 and the cover tape 1, and the base material layer is exposed facing the carrier tape 2. Further, for the purpose of further improving the separation between the cover tape and the part presser 7 in the cut portion 12, a perforation may be provided in the cut portion 12 so as to partially penetrate the base material layer.

  Usually, the cover tape has a uniform adhesive layer on the surface of the base material layer, and the adhesiveness of the area where the parts are pressed is the same as that of the other areas. It may be stronger.

  FIG. 2 is an image view in which a part of the cover tape of the transport packaging tape shown in FIG. 1 is peeled off. The peeled cover tape 6 is separated from the carrier tape 2, and the component presser 7 is further removed to form an opening 10 along the cut portion 12. The component presser 7 that is a part of the cover tape is fixed to the carrier tape 2 with an adhesive portion 8. At this time, when the transport packaging tape is viewed from the cover tape side, the component presser 7 bonded to the carrier tape 2 must be overlapped with the component 4 without fail. However, when the suction nozzle of the automatic mounting machine picks up the component, the suction nozzle sucks the vicinity of the center of the component, so the component presser 7 should not be near the center of the component 4 but overlap the periphery of the component 4. Are arranged as follows.

  FIG. 3 is a side view of FIG. 2 viewed from the side. The thickness of the cover tape 6 is greatly exaggerated. The component 4 is stored in the pocket 3 of the carrier tape 2. The component presser 7 is fixed to the carrier tape 1 and further overlaps a part of the component 4 in the vertical direction.

  FIG. 4 is an image diagram of a second embodiment according to the present invention. This is an example in which the component pressers 7 are arranged at two opposite corners of the four corners of the pocket 3. Thereby, it overlaps with the two corners on the diagonal of the component 4. Thus, the location, shape, size, and quantity of the component presser 7 can be changed according to the size and shape of the component.

  One component holder 7 needs to be fixed to only one side of the four sides of the pocket 3. The reason is that if one component retainer is fixed across a plurality of sides of the pocket, the strength of the component retainer 7 made of a thin film increases, which hinders the removal of the component 4. .

  FIG. 5 is an image diagram of a third embodiment according to the present invention. The component presser 7 is fixed to the two sides of the pocket 3 with an adhesive portion 8. Since the two adhesive portions 8 are used for fixing, the component presser 7 is fixed to the carrier tape 2 more stably. However, as described with reference to FIG. 4, since the two parts of the pocket 3 are fixed, the part presser 7 is difficult to turn over, and there is a possibility that it becomes an obstacle when the part 4 is taken out. Therefore, in the case of such a pressing method, it is necessary to reduce the overlapping area of the component presser 7 and the component 4 as much as possible.

  FIG. 6 is an image diagram of a fourth embodiment according to the present invention. The part presser 7 is formed in the traveling direction side of the transport packaging tape. Most of the component presser 7 is disposed between the pockets 3, and a part thereof protrudes from the pocket 3 so as to overlap the pocket 3 and the component 4. In this example, the component presser 7 is formed in the conveyance packaging tape traveling direction, but it can also be formed on the opposite side to the traveling direction or on both sides. Since the vibration applied to the transport and packaging tape differs depending on the size of the component 4 or the pocket 3 or the automatic mounting machine, it is also effective to change the position, size, and shape of the component press as shown in this figure depending on the situation.

  In the embodiment shown in FIGS. 4 to 6, the positioning hole 9 of the cover tape shown in FIGS. This is because, even if the positioning holes are not formed in the cover tape, the component pressers 7 are formed at an equal pitch, so the position of the first component presser 7 and the pocket 3 of the carrier tape 2 can be visually observed or by an image processing device. This is because they can be bonded together.

FIG. 7 shows a state in which the suction nozzle 11 of the automatic mounting machine is sucking the component 4 in the pocket 3 with respect to the transport packaging tape of the case shown in FIG.
As shown in the figure, since the suction nozzle 11 sucks the vicinity of the center of the component 4, the component presser 7 needs to be formed at a position that does not hinder the operation of the suction nozzle 11.

  FIG. 8 is a cross-sectional view taken along the cutting plane AA as viewed from the short side direction of the transport and packaging tape shown in FIG. A state in which the suction nozzle 11 sucks the component 4 and removes it from the pocket 3 is shown. Since the part presser 7 is made of a thin film, it is easily bent and does not prevent the part 4 from being taken out.
