The number of laminated substrates 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 dirt of the mold and displacement of the substrate for the printed circuit board are serious obstacles to efficient production of the integrated printed circuit board. Therefore, the side surface of the base material for the integrated printed circuit board is pasted with tape so that the mold is not contaminated due to 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 is
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 to stick the side surface of the base material for integrated printed circuit board with a continuous tape by an automatic tape sticking machine, but it is necessary to perform a work of cutting the tape connecting the integrated base materials. However, when the connecting tape between the integrated printed circuit board bases is cut, the adhesive 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.

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 ° from the transfer direction. The sticking of the continuous tape is performed to prevent the thermosetting resin leakage in the integrated base material or the positional deviation of the integrated base material when the integrated base material is heated and pressed thereafter, and is usually used for the integrated base material. 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.

The present invention is not limited to these examples. FIG. 1 is a plan view showing an arrangement of a continuous integrated device for a printed circuit board base material, which can suitably use the cutting device for a connecting tape for an integrated printed circuit board base material of the present invention. Substrate feeder 1, 2, 3, 4
4 of the base material feeders are arranged in series on one side of the 4 mounting bases of the mounting bases 9, 10, 11, 12 and between the respective base material supply machines and the mounting bases. Substrate supply bases 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 substrates 22 placed on the placing 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. The base material 22 is stopped by stopping the base material transfer belt when the base material 22 is moved to a predetermined position on the mounting table 10 by means of. 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 printed circuit board substrate or the substrate supply. It may be appropriately selected according to the speed and the transfer speed. In addition, by changing the base material supply speed of each base material feeder, the number of base materials supplied from each base material feeder can be changed to continuously and smoothly accumulate, but as will be described later. When a plurality of base materials supplied from each base material supply device are supplied to the mounting table at the same time by supplying the base materials, the base materials can be more efficiently accumulated. In FIG. 1, when the base material supply speed from each base material supply device is limited, for example, when 8 base materials are accumulated, a plurality of base material simultaneous supply devices are attached to the base material supply devices 2 and 3, respectively. When the number of the base materials supplied from the base material supply machines 1, 2, 3 and 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 it out.

As described above, in order to feed the base material from the base material feeder, 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, the sheet is sent to the tape sealing machine 16 by the base material feed belt 15 of the transfer direction changing table 14. It should be noted that 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 material leaking from the side surface of the base material 22 in the prevention of misalignment of the stacked base material 22 or the subsequent pressing process. It is provided with a function of preventing impregnated resin such as resin from adhering to the pressing mold.

Next, the laminated base material 22 is

The number of the base material feeders is not particularly limited and may be appropriately selected and determined. The base material feeders may be arranged in various ways, as shown in FIG. Not necessarily, Figure 2
As shown in (2), two substrate feeders may be arranged with one mounting table interposed therebetween. Further, the material of the belt for transferring the base material is not particularly limited, but for example, rubberized cloth is preferable. FIG. 3 is a cross-sectional view of the substrate supply machine 1, the substrate 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 upward as the base material 22 is sent out, so that the position of the upper surface of the stacked base material 22 is always at a constant height. Lifting of the pallet 21 is performed by an elevating motor or the like which is operated by a signal from a leveler switch. In addition, the base material 22 stacked on the pallet 21
When all the sheets have been sent out, the pallet 21 on which another base material 22 is stacked can be carried by the chain conveyor 35. On top of the stacked base materials, the base material 22 is arranged in
A first suction tool 23 and a second suction tool 24 capable of sucking and lifting the first suction tool 23 are provided.
As a result, one end of the substrate 22 is lifted. Next, although not shown, air is blown into the gap between the lifted base material 22 and the stacked base material 22 from an air outlet to prevent entrainment of the fed base material 22 with the next base material 22. In addition, the feeding of the base material 22 is made smooth.

Next, after the substrate 22 is sucked by 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 by the
And 28. The vertical and horizontal movements of these suction tools are performed by rollers with rollers that slide and move on the outer circumference of the suction tool operation cam 25 and a link mechanism connecting these levers. 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 send the base material 22 to the base material supply table 5 arranged ahead of the base material 22. The substrate supply table 5 is provided with a delivery roll 29 disposed at the tip thereof.
It is composed of a plurality of belt-shaped base material supply belts 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. A press roll 30 is pressed against the feed roll 29 by a spring, and can move up and down according to the thickness of the base material 22 to be fed.

The structure of the substrate supply table is not limited to the one configured by the belt as described above, and the substrate 22 sent from the substrate supply machine can be placed on the table 9. Various structures can be used as long as they can be used. 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 transport belts 32 constituting the mounting table 9, and the substrate 22 enters between the substrate transport belts 32. Not to be. The corrugated plate 33 can slide the substrate 22 sent from the substrate supply table 5 so that the tip of the substrate 22 comes to the openable stopper 34. Thereafter, the corrugated plate 33 descends, and the substrate 22 comes into contact with the substrate transport belt 32. The structure of the corrugated plate 33 is not particularly limited as long as it can slide the fed base material 22 so that the front end of the base material 22 comes to the position of the openable stopper 34. Although various structures can be used, it is preferable that one waveform has a gentle slope with a forward rise as shown in FIG. 1 and a 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. Further, the corrugated plate 33 may be raised from below and moved so as to be positioned in the gap of the belt as shown in FIG. 1, or may be lowered from above and moved to a predetermined position in the gap of the belt. Alternatively, 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 configured by a plurality of belt-shaped substrate transfer belts, but this belt is not limited to a plurality of belt-shaped belts and has no gap. Although it may be constituted by one belt, if it is constituted by a plurality of belts, the base material 2
It is preferable because it can prevent meandering when transferring 2. When configured with 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 need to be constituted by a belt, but may be constituted by a plate, but is preferably constituted by a belt. In addition, the corrugated plate 33 is
Instead of moving up and down from between the base material transfer belts 32 as described above, a type that can slide the upper surface of the mounting table 9 in the horizontal direction may be used. 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 open / close stopper 34 may not be of the open / close type, and may have any structure as long as it can stop 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.

Further, in order to more accurately position the substrate 22, in addition to the two stoppers, an alignment ruler is provided before and after in the transfer direction of the substrate 22 placed on the mounting table 9, It is preferable to swing together with the two stoppers. Such an alignment ruler is used when the base material 22 is transferred.
What is necessary is just to remove from the transfer direction so as not to hinder 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. In the case of the apparatus shown in FIG. 3, the feeding speed is 80 sheets / minute, and the base material 22 can be extremely efficiently accumulated. After the accumulation of the base material 22 on the mounting table 9 is completed, the base material 22 is transferred to the next mounting table or the next step. The transfer of the base material 22 can be performed by driving the transfer belt when the mounting table is provided with the 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-like belts and a corrugated plate is provided on the belt-like belt, this belt may be driven continuously, It may be driven intermittently.
