The number of laminated base materials for a printed circuit board varies depending on the intended use and application of the printed circuit board, and is usually 2 to 8, and in many cases, may exceed 10. At present, the integrated printed circuit board substrate is heated and pressed to complete a printed circuit board product. The thermosetting resin present may leak from the side surface of the base material and stain the pressing mold. In addition, the substrate for the integrated printed circuit board may be displaced. Such stains on the mold and displacement of the printed circuit board base material are serious obstacles to efficient production of the integrated printed circuit board. Therefore, the side surface of the base material for integrated printed circuit board is attached with tape so that the mold is not contaminated due to the leakage of the thermosetting resin and the positional deviation of the integrated base material does not occur. There is. By the way, pasting with this tape
This is all manual work, which has been a serious obstacle to mass production and cost reduction of printed circuit boards. Therefore, it is conceivable that the side surface of the substrate for integrated printed circuit board is pasted with a continuous tape by an automatic tape pasting machine, but it is necessary to perform a work of cutting the tape connecting the respective integrated substrates. However, when the connecting tape between the integrated printed circuit board bases is cut, the adhesive agent of the tape adheres to the cutting blade and accumulates, and eventually it becomes impossible to cut, and the cutting is efficient. The problem came out that I could not do it.

In addition, the transfer direction of the integrated base material is such that continuous tapes are attached to both ends in the width direction which is deviated by 90 ° with respect to the transfer direction. The sticking of the continuous tape is performed in order to prevent the thermosetting resin from leaking in the integrated base material or the positional displacement of the integrated base material when the integrated base material is heated and pressed thereafter. Both ends of the tape are attached to the respective surfaces of both ends. The continuous tape is not particularly limited as long as it can be attached to the side surface of the integrated base material, but is preferably an adhesive tape, and in particular, an adhesive is applied to the portion covering the side surface of the integrated base material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below more specifically with reference to the drawings. The present invention is not limited to these examples. FIG. 1 is a plan view showing the arrangement of a continuous integrated device for a printed circuit board substrate, which can suitably use the cutting device for a connecting tape for an integrated printed circuit board substrate according to the present invention. Substrate feeder 1, 2, 3, 4
The four base material feeders are arranged in series on one side of the four mounting bases 9, 10, 11 and 12 in series, and between the respective base material supply machines and the mounting bases. Substrate supply tables 5, 6, 7, and 8 are arranged in each. First, the base material 22 made of the base material for a printed circuit board or the base material laminated on the base material for a printed circuit board is supplied one by one from the base material supply device 1 and placed on the base material supply table 5. Then, the substrate 22 is
The base material supply belt 31 of the base material supply table 5 is driven to place the base material on the mounting table 9.

The number of the base materials 22 placed on the mounting table 9 may be one, or two or more. Next, the base material transfer belt 32 of the mounting table 9 is driven, the base material 22 placed on the mounting table 9 is transferred to the adjacent mounting table 10, and the base material transfer belt of the mounting table 10 is also driven. When the base material 22 is moved to a predetermined position on the mounting table 10 by means of the above, the base material transfer belt is stopped and the base material 22 is stopped. Next, another base material 22 is supplied one by one from the base material supply device 2 and placed on the base material supply table 6.
Next, the base material 22 is placed on the mounting table 10 by driving the base material supply belt of the base material supply table 6.

Next, the base material 22 laminated on the mounting table 10 is sequentially transferred to the mounting tables 11 and 12 in the same manner.
A predetermined number of different base materials 22 supplied from the base material supply machines 3 and 4 are stacked, the base materials are integrated, and the step of integrating the base material for a printed circuit board is completed.

As described above, the number of substrates supplied by each of the substrate feeders 1 to 4 is not particularly limited, and the required characteristics of the substrate for the printed circuit board or the supply of the substrate is required. It may be appropriately selected according to the speed and the transfer speed. It should be noted that by changing the base material supply speed of each base material supply machine, the number of base materials supplied from each base material supply machine can be changed to smoothly and continuously accumulate the base materials, as will be described later. In addition, when a plurality of substrates simultaneously supplied from the respective substrate feeders can be simultaneously placed on the mounting table, the substrates can be more efficiently integrated by supplying the substrates. In FIG. 1, when the base material supply speed from each base material supply machine is limited, for example, when eight base materials are stacked, a plurality of base material simultaneous supply devices are attached to the base material supply machines 2 and 3, respectively. When the number of base materials supplied from the base material supply machines 1, 2, 3, 4 is set to 1, 3, 3, and 1, respectively, it is possible to efficiently accumulate the base materials. In addition, it is important that the direction in which the base material 22 is sent out from each base material feeder is the direction in which the width of the base material 22 is short in order to efficiently send out.

As described above, in order to feed the base material from the base material supply device, place the base material on the mounting table, transfer the base material on the mounting table, and accumulate the base material on the mounting table. The timings of driving and stopping the respective devices are synchronized with each other and can be continuously and efficiently performed. The accumulated base material is then transferred onto the transfer direction changing table 14 by the roll 13, and the transfer direction is set to 9
It is changed by 0 °. Further, it is sent to the tape sealing machine 16 by the base material feed belt 15 of the transfer direction changing table 14. In addition, the transfer from the transfer direction changing table 14 to the tape sealing machine 16 does not depend on the base material feeding belt 15, but a plurality of air ejection ports are provided on the transfer direction changing table 14 and the ejected air is ejected. Thus, the base material 22 can be floated and transferred by a force such as a kicking tool. The base material 22 transferred to the tape sealing machine is sealed with a continuous tape on both side surfaces in the transfer direction, and the epoxy is leaked from the side surface of the base material 22 in order to prevent displacement of the stacked base materials 22 or in a subsequent pressing step. A function of preventing the impregnated resin such as resin from adhering to the pressure die is provided.

Next, the laminated base material 22 is rolled into a roll 1.
It is transferred to the turntable 19 via 8, and is transferred to the loading device 20 after being changed in an appropriate direction. The number of base material feeders is not particularly limited and may be appropriately selected and determined. Further, the base material feeders may be arranged in various ways, as shown in FIG. Not necessarily, Figure 2
As shown in FIG. 2, two base material feeders may be arranged with one mounting base interposed therebetween. Further, the material of the belt for transferring the base material is not particularly limited, but, for example, a rubberized cloth or the like is preferable. FIG. 3 is a cross-sectional view of the base material supply device 1, the base material supply table 5, and the mounting table 9 of FIG. In the base material supply device 1, the base materials 22 stacked on the pallet 21 are placed, and the base materials 22 are sent out one by one from the top of the stacked base materials 22.

The pallet 21 is sequentially lifted up as the base materials 22 are sent out, and the position of the upper surface of the stacked base materials 22 is always kept at a constant height. The pallet 21 is lifted by an elevating motor or the like that operates in response to a signal from the leveler switch. In addition, the base material 22 stacked on the pallet 21
When all the sheets have been sent out, the chain conveyor 35 can carry the pallet 21 on which another base material 22 is stacked. On top of the stacked base materials, the base material 22 is arranged in
The first suction tool 23 and the second suction tool 24 capable of sucking and lifting the first suction tool 23 are provided.
Thus, one end of the base material 22 is lifted. Then, although not shown, air is blown into the gap between the lifted base material 22 and the stacked base material 22 from an air ejection port to prevent the base material 22 to be sent out and the next base material 22 from being entrained. , To facilitate the delivery of the base material 22.

Next, after sucking the base material 22 with the second suction tool 24, the suction of the first suction tool 23 is stopped, and the second suction tool 24 is stopped.
The second suction tool 24 is moved in the feeding direction of the base material 22 while holding the base material 22 with the nip roll 27.
And put it between 28. The vertical and horizontal movements of these suction tools are performed by a lever with a roller that moves by sliding on the outer circumference of the suction tool operating cam 25 and a link mechanism that connects them. The nip roll 27 is pressed against the nip roll 28 by a spring and can move up and down according to the thickness of the substrate 22. The nip rolls 27 and 28 are rotationally driven to feed the base material 22 to the base material supply table 5 arranged ahead of the base material 22. The base material supply table 5 has a delivery roll 29 arranged at its tip.
It is composed of a plurality of belt-shaped base material supply belts that are hung on the nip roll 27, and the base material 22 can be sent out onto the mounting table 9 by driving the base material supply belts. Further, the pressing roll 30 is pressed against the delivery roll 29 by a spring, and can be moved vertically depending on the thickness of the substrate 22 to be delivered.

The structure of the base material supply table is not limited to the structure composed of the belt as described above, and the base material 22 sent from the base material supply machine may be placed on the mounting table 9. Various structures can be used as long as they can be formed. For example, a plate or the like may be used instead of the belt.
Alternatively, the base material 22 may be directly supplied from the base material supply machine 1 to the mounting table 9 without providing the base material supply table. The base material 22 is
When placed on the mounting table 9, the corrugated plate 33 is lifted up from between the plurality of belt-shaped substrate transfer belts 32 forming the mounting table 9 so that the substrate 22 enters between the substrate transfer belts 32. Try not to. The corrugated plate 33 can slide the base material 22 sent from the base material supply table 5 so that the tip of the base material 22 comes to the openable stopper 34. Thereafter, the corrugated plate 33 descends and the base material 22 contacts the base material transfer belt 32. The structure of the corrugated plate 33 is not particularly limited as long as the fed base material 22 can be slid so that the tip of the base material 22 comes to the position of the open / close type stopper 34. Although various structures can be used, it is preferable that one corrugation has a gentle slope that rises forward as shown in FIG. 1 and that the tip portion near the edge of the next belt is higher than the upper surface of the belt. ..

Further, the corrugated plate 33 may be integrated as shown in FIG. 1 or may be divided at each gap of the belt. Alternatively, the corrugated plate 33 may be moved upward so as to be positioned in the gap between the belts as shown in FIG. 1, or may be moved downward to be moved to a predetermined position in the gap between the belts. Well, it may be moved horizontally from the side. The corrugated plate 33 is necessary only when the base material 22 that is first placed on the mounting table is sent out, and is not necessary when the second and subsequent base materials 22 are mounted on the mounting table. Further, in FIG. 3, the mounting table 9 is composed of a plurality of belt-shaped substrate transfer belts, but this belt is not limited to one composed of a plurality of belt-shaped belts, and there is no gap. Although it may be composed of one belt, if it is composed of a plurality of belts, the base material 2
It is preferable because it can prevent meandering when transferring 2. When composed of a plurality of belts, the number of belts is not particularly limited, but is usually 3 to 8,
It is preferably 4 to 6.

The mounting table 9 does not necessarily have to be formed of a belt, and may be formed of a plate, but it is preferably formed of a belt. The corrugated plate 33 is
Instead of vertically moving from between the base material transfer belts 32 as described above, the upper surface of the mounting table 9 may be horizontally slidable. When the base material transfer belt is composed of one belt-shaped belt, the corrugated plate 33 is not necessary because the base material 22 is not likely to enter between the belt-shaped belts. Further, the openable / closable stopper 34 need not be an openable / closable stopper, and may have a structure capable of stopping the base material 22 at a predetermined position on the mounting table 9. In addition to the opening / closing stopper 34, it is preferable to provide an aligning ruler on the front side of the base material 22 in the feeding direction, because the base material 22 can be positioned more accurately.

In order to make the positioning of the base material 22 more accurate, in addition to the above two stoppers, aligning rulers are provided before and after the base material 22 placed on the mounting table 9 in the transfer direction. It is preferable to swing together with the two stoppers. Such an alignment ruler is used when the base material 22 is transferred.
It should be removed from the transfer direction so as not to obstruct the transfer. As described above, each part makes continuous movements, but it is preferable that these movements be controlled by the tuning mechanism. The feeding speed of the base material 22 depends on the feeding capacity of the base material feeder, but in the case of the apparatus of FIG. 3, it is 80 sheets / minute, and the base material 22 could be accumulated extremely efficiently. After the accumulation of the substrate 22 on the mounting table 9 is completed, the substrate 22 is transferred to the next mounting table or the next process. The transfer of the base material 22 can be performed by driving the transfer belt when the mounting table includes a transfer belt, or by a method of gripping and transferring the base material 22. When the mounting table 9 is composed of a plurality of belt-shaped belts and the corrugated plate is provided on the belt-shaped belts, the belts may be continuously driven, and when the base material 22 is transferred. You may drive intermittently.

The other base material feeders, the base material supply bases, and the mounting bases in FIG. 1 have the same structures as those in FIG. FIG. 4 is a cross-sectional view of a base material feeding device showing another mechanism for mounting the base material 22 on the mounting table. The base material 22 is sent out from the base material supply table 5 similarly to FIG. 3, and then received by the base material receiving fork 41 arranged on the mounting table 9.
