Apparatus for cutting of ceramic green sheet

The present invention relates to, for example, a cutting device for ceramic green sheets used as raw materials in a manufacturing system for manufacturing parts such as a multilayer ceramic capacitor (MLCC). In detail, when cutting the ceramic green sheet, it is possible to prevent the occurrence of scraps of the sheet, thereby eliminating various damages caused by the scrap, to produce a higher quality multilayer ceramic capacitor, and to prevent malfunction and failure of the manufacturing system. The present invention relates to a cutting device for a ceramic green sheet, which reduces the number of operations for cutting the ceramic green sheet and contributes to the improvement of the productivity of the multilayer ceramic capacitor.

In general, multilayer ceramic capacitors are mounted on printed circuit boards of various electronic products such as mobile communication terminals, notebook PCs, personal digital assistants (PDAs), and digital TVs. It is known as capacity, and has various sizes and stacking forms depending on the use purpose and capacity.

In order to manufacture the multilayer ceramic capacitor as described above, a molding process of continuously coating a slurry-type ceramic in a thin thickness of several micrometers to several tens of micrometers on a continuous PET film, and on the surface of the coated ceramic A printing process of printing a predetermined pattern to produce a ceramic green sheet, a cutting process of cutting the ceramic green sheet into a predetermined shape for each printing pattern from the PET film, and a predetermined shape from the PET film A peeling step of separating the cut ceramic green sheet, a laminating step of laminating the ceramic green sheet separated from the PET film in a predetermined number of layers, a crimping step of pressing the laminated ceramic green sheet at a predetermined pressure, and the like. It is supposed to be.

In the series of manufacturing processes described above, a typical embodiment of a cutting process of cutting a ceramic green sheet into a predetermined shape for each printing pattern from a PET film will be described with reference to the accompanying drawings.

As shown in Figs. 1 to 3, when the take up roll 1 and the supply roll 2 provided at a predetermined portion of the apparatus main body are rotated at a predetermined constant speed, the supply roll From (2), the PET film F on which the ceramic green sheet S is printed is released. At this time, the suction roll in the lower portion of the transport path inlet side of the PET film (F)

(3) is provided, and since the horizontal cutters 4 and 4 'are rotatably provided at both upper ends thereof, the ceramic green is interposed between the suction rolls 3 and the horizontal cutters 4 and 4'. As the PET film F on which the sheet S is printed is passed, only the ceramic green sheet S is cut in the transverse direction leaving both sides. PET film F with high strength is not cut | disconnected in the cutting | disconnection work by the above-mentioned horizontal cutters 4 and 4 '.

As described above, in the process in which the PET film F is advanced by the rotation operation of the supply roll 1 and the winding roll 2, the horizontal cutters 4 and 4 ′ are always operated to ceramic green of the PET film F. The operation of cutting the sheet S in the transverse direction is continuously performed.

On the other hand, the head slider 5 which is operated by the drive of a normal cylinder is provided in the rear side of the said horizontal cutter 4, 4 ', and the head slider 5 is a longitudinal cutter of both sides.

(6) (7) and the lower peeling head 8 are provided, and the seed cutter die 9 is provided in the lower side.

Therefore, as described above, the PET film F with the ceramic green sheet S cut laterally by the transverse cutters 4 and 4 'is attached to the head slider 5 and the longitudinal cutter die 9. At the moment of passing through), the head slider 5 is lowered and the seed cutter 6 is removed from both sides while the peeling head 8 presses the ceramic green sheet S at a predetermined pressure. As the 7 moves in the longitudinal direction, the printed pattern P of the ceramic green sheet F is cut into a quadrangular shape.

Thereafter, the printed pattern P of the ceramic green sheet S is peeled off from the PET film F by a peeling process, and then sequentially stacked on the laminating machine 10 with a predetermined number of layers in a conventional crimping process. At the same time, the PET film F, in which the printing pattern P is peeled off in a rectangular shape, is wound on the take-up roll 1.

At this time, as shown in Figs. 4 and 5, the rectangular printing pattern (P) of the ceramic green sheet (S) is sequentially stacked on the laminator 10, the rectangular electrode pattern (E) In order to connect at both ends, the head slider 5 cuts the printing pattern P while performing an overlap alternately by a predetermined distance d.

Being made in a separate step each had a number of problems.

That is, as shown in FIG. 2, the longitudinal cutting operation is performed by the longitudinal cutters 6 and 7 in the state in which both side edge portions of the ceramic green sheet S are cut by the horizontal cutters 4 and 4 ′. Since the rectangular ceramic pattern S is cut off from both sides of the initial ceramic green sheet S, the rectangular ceramic pattern S 'is generated between the rectangular print patterns P.

Since the ceramic ceramic sheet S 'is coated on the PET film F with a thin thickness of several micrometers to several tens of micrometers, the phenomenon of easily falling off from the PET film F due to static electricity or the like occurs. The phenomenon in which the cut ceramic sheet S 'is blown into the inside of the manufacturing system frequently occurs, and in particular, when flying toward the lamination machine 10, the laminated ceramic sheet S' is stuck to the laminated print pattern P or the lamination head. Not only does it lower the performance of the ceramic capacitor, but also the longitudinal cutting is performed after the lateral cutting operation of the ceramic green sheet (S) does not exclude the possibility of error occurrence, and also the main part of the manufacturing system There was a drawback to malfunction and cause a malfunction.

In addition, there are various problems, such as increasing the number of work for cutting the ceramic green sheet to act as a factor for reducing the productivity improvement of the multilayer ceramic capacitor.

The main object of the present invention is to provide a cutting device of a ceramic green sheet which can produce a higher quality laminated ceramic capacitor by eliminating various detriments caused by the dropping of the sheet to prevent the occurrence of cuts of the sheet during the cutting operation of the ceramic green sheet. have.

Another object of the present invention is to provide a cutting device of a ceramic green sheet which can prevent malfunction and failure of a manufacturing system due to a pottery ceramic sheet.

It is still another object of the present invention to provide a cutting device for ceramic green sheets, which can contribute to the improvement of productivity of a multilayer ceramic capacitor by reducing the labor for cutting the ceramic green sheets.

Referring to the operation of the ceramic green sheet cutting device according to the present invention configured as described above are as follows.

As the PET film F is transported along the transport path by the transport mechanism of the conventional manufacturing system, as shown in FIG. 11 in the state in which the transport operation of the PET film F is performed, the cutting unit body Since the bracket 92 installed at the lower portion of each slider 50 of the 30 is mounted on the stopper 100 fixed to each pillar member 30, the cutting blade 93 is a PET film (F). It does not touch the ceramic green sheet (S). At this time, the elastic member 91 is maintained in a compressed state.

After that, when the cutting position of the ceramic green sheet S is reached, the PET film F stops at the cutting position of the cutting table 19.

At this time, since the vacuum pressure is supplied to the cutting table 19 through a vacuum line (not shown), the vacuum pressure acts on the minute pores formed on the surface, thereby adsorbing and fixing the PET film F to the lower side. F) can be prevented from moving in any direction.

As described above, when power is applied to the driving means in a state where the PET film F is firmly fixed to the upper surface of the cutting table 19 by the vacuum pressure, the rotary block 70 is driven by the power of the rotating cylinder 110, The four movable guide members 80 provided in the rotary block 70 are rotated at the same time.

Thereafter, the vacuum pressure applied to the cutting table 19 is released and the PET film F is transferred by a predetermined length, and then the vacuum pressure is supplied to the cutting table 19 to hold the PET film F. By driving the driving means in reverse to reverse the rotation direction of the rotary block 70, the respective sliders 50 are linearly moved in the reverse direction to cut the printed pattern P of the ceramic green sheet S into quadrangles.

At this time, as shown in Figs. 4 and 5, in order to sequentially laminate the rectangular printed pattern P of the ceramic green sheet S on the laminator 10 of the manufacturing system, the rectangular electrode pattern E ), The printing pattern P should be cut while overlapping alternately by a constant distance d.

Therefore, the cutting unit body 30 should be linearly moved by a predetermined distance d in the left and right directions, and the series of operations will be described as follows.
