Description

  The present invention relates to the manufacture of a flexible substrate, and more particularly to a flexible substrate punching apparatus and a flexible substrate guide rail that require continuous punching with a mold in a flexible substrate without a backing material.

  The flexible substrate is manufactured while a long flexible base material such as a polyimide film is wound around a reel and is flowed to a production line. The flexible substrate undergoes press working including punching of a guide hole (perforation), a positioning hole according to the model, and a device hole if necessary. The flexible substrate is as thin and soft as several tens of μm, and measures are taken to increase the thickness by adhering the backing material to the main body flexible base material and to reinforce it. For the backing material, for example, a pet material having a thickness of about 100 μm is used. Thereby, when punching with a metal mold | die, a flexible base material obtains actions and effects such as improvement of punching accuracy, correction of warpage, distortion suppression during punching or feeding.

  According to the above measures, the flexible substrate costs for the backing material and the adhesive material. In addition, a bonding process of the backing material before punching and a peeling process of the backing material after punching are necessary. Moreover, deterioration of the mold is promoted by punching each backing material. In addition, since the tape thickness is increased, there is a restriction on the maximum length that can be wound on the reel, which is disadvantageous in terms of processing with a long lot.

Moreover, the structure using a board | substrate pressing sheet is disclosed as a countermeasure which raises the precision improvement of the die-cutting of a flexible substrate (for example, refer patent document 1). The substrate pressing sheet is positioned between the pressing plate and the flexible substrate on the mold without being bonded to the flexible substrate. Thereby, the flexible substrate and the substrate pressing sheet are simultaneously punched to ensure punching accuracy and protect the die blade.

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is an external view showing a main part of the flexible substrate punching apparatus according to the first embodiment of the present invention, and FIG. 2 is a sectional view taken along line F2-F2 of FIG.
The upper mold 11 and the lower mold 12 are related to the press working operation by the press mechanism 10. The long flexible base material 13 is not provided with a backing material. As the flexible base material 13, for example, one having a metal surface before the circuit pattern is formed or after the circuit pattern is formed is handled. For example, a press in a state where a copper foil is laminated, or a press for cutting unnecessary wiring after the electrolytic plating process can be considered. The flexible base 13 is fed between the upper mold 11 and the lower mold 12, and a hole is opened in a predetermined portion by a press working operation. Here, the upper mold 11 is configured so that the pressing operation of the flexible base material 13 is controlled by the press mechanism 10, and the lower mold 12 receives the pressing force of the upper mold 11.

  The upper mold 11 includes, for example, a stripper plate 111 for positioning / a punching plate 112 with a mold (pin or protrusion not shown) for punching / a backing plate 113 for reinforcement. / Die set member 114 is included. Further, the lower mold 12 includes a combination form of a die plate 121 for punch reception / backing plate 122 for reinforcement / die set member 123 from the flexible substrate 13 side downward. The die set members 114 and 123 are movably coupled by a plurality of sub posts (sub cylinders) 14. The die set members 114 and 123 are mainly made of, for example, aluminum, and the other plates are made of, for example, steel.

  A guide rail 15 is provided between the upper mold 11 and the lower mold 12. The guide rail 15 is a metal member arranged to maintain the state of the flexible base material 13, and the front and rear of the flexible base material 13 in the feed direction centered between the upper mold 11 and the lower mold 12. Each L2 extends over a dozen centimeters and surrounds a part of the flexible substrate 13. More specifically, the guide rail 15 is a metal member mainly composed of aluminum. The central region of the guide rail 15 is fitted and fixed on the die plate 121 in the lower mold 12. However, although this fixed area (center area) is not shown, the punch receiving area (hole, etc.) of the die plate 121 is a pattern that is avoided. There may be a screwing mechanism at any location along with the fitting and fixing. The guide rail 15 can be removed. The guide rail 15 fixed to the lower mold 12 is processed so as to surround the lower surface and side portions of the flexible base material 13 and a part of the upper surface connected to the side portions in the extended region (see FIG. 2).

  The thickness of the flexible base material 13 without the backing material is smaller than 100 μm. The guide rail 15 is configured such that the distance from the lower surface of the flexible base material 13 and the distance from the upper surface of the flexible base material 13 are each less than 200 μm. For example, if the thickness of the flexible base material 13 is about 50 μm, the gap G on both sides of the guide rail 15 is about 400 μm. The width W that covers the upper surface of the flexible substrate 13 is about a few tens of millimeters.

  The flexible base material 13 passes through the guide rail 15 and is fed between the upper mold 11 and the lower mold 12 and punched as follows. The press mechanism 10 applies a pressing force to the die set member 114 in the upper mold 11 and pushes the punching plate 112 downward through the backing plate 113. The stripper plate 111 comes into contact with the flexible substrate 13, and the punching plate 112 mold protrudes from the stripper plate 111 by about 0.2 mm. The die plate 121 below the flexible substrate 13 is a female die and receives a punching die, and the impact is absorbed by the backing plate 122 and the die set member 123.

  The guide rail 15 has a length (L1, L2) that is equal to or longer than the region for one step of the pressing operation of the flexible base material 13 in the press mechanism 10 before and after the feeding direction of the flexible base material 13. Moreover, as described above, the flexible base material 13 has a lower surface, side portions, and an upper surface portion connected to the side portions so as to reinforce the fragile flexible base material 13. Thereby, the punching accuracy of the flexible base material 13 without the backing material is improved.

  According to the structure of the said embodiment, the guide rail 15 for flexible base materials 13 is provided in a metal mold | die (12). The guide rail 15 extends between the upper die 11 and the lower die 12 in the front and rear in the feeding direction of the flexible base material 13, and a part of the flexible base material 13, i. Enclose a part of the upper surface to be connected with a slight gap. The guide rail 15 contributes to correction of distortion and warping of the fragile flexible base material 13 without the backing. The guide rail 15 has a function of reinforcing the flexible base material 13 around the press working operation. Thereby, when performing continuous punching with the molds 11 and 12, warping and distortion due to the fragility of the flexible base material 13 are suppressed, and punching accuracy is improved.

  FIG. 3 is a block diagram showing the main part of the line of the flexible substrate punching apparatus according to the second embodiment of the present invention. A press mechanism 10 and dies 11 and 12 provided with a guide rail 15 shown in FIG. 1 are used. A feed mechanism 22 that repeatedly feeds the long flexible base material 13 for a certain length is provided after the press working operation. The flexible base material 13 without the backing material is sequentially guided from the loader unit 21 through the guide rail 15 to the molds 11 and 12 controlled by the press mechanism 10 by the feed mechanism 22. The flexible base material 13 is prevented from warping and distortion by the guide rail 15 and realizes high-accuracy punching. The unloader unit 23 sequentially winds the pressed flexible base material 13 sequentially sent from the feed mechanism 22.

  In the configuration of the above embodiment, the same effect as that of the first embodiment can be obtained. That is, the guide rail 15 extends between the upper die 11 and the lower die 12 in the front and rear in the feeding direction of the flexible base material 13 to reinforce the periphery of the pressing operation of the flexible base material 13. Thereby, even the fragile flexible base material 13 having no backing is suppressed in distortion and warpage, and the punching accuracy is improved even when continuous punching with the molds 11 and 12 is performed.

  FIG. 4 is a schematic view showing a main part of a flexible base guide rail according to the third embodiment of the present invention. The metal member 30 is the same as the guide rail 15 used in FIG. That is, the long flexible base material 15 is fed and processed so as to surround the lower surface of the flexible base material 13 and the side portion and a part of the upper surface connected to the side portion with a slight separation distance. The flexible substrate has a thickness of less than 100 μm. The metal member 30 is configured such that the distance from the lower surface of the flexible substrate 13 and the distance from the upper surface are less than 200 μm. The metal member 30 may be made of stainless steel or steel in addition to aluminum.

  The metal member 30 is provided with a fixing region 301 for fixing to another member. The flexible base material 13 is sent to the guide rail of the metal member 30 for processing, and is sent out from the guide rail of the metal member 30 through the processing environment. Since the flexible base material 13 is continuous, the accuracy of the metal member 30 surrounding the flexible base material 13 before and after processing the flexible base material 13 is improved. Therefore, the fixed region 301 is disposed in a region between the metal member 30 before and after processing the flexible base material 13. That is, in FIG. 1, the fixed region 301 is fitted on the die plate 121 in the lower mold 12. It is important that the fixing region 301 has a pattern that does not hinder the processing on the flexible base material 13.

  According to the structure of the said embodiment, the metal member 30 comprises a flexible base material guide rail. The flexible base guide rail made of the metal member 30 can be used in any process or apparatus for manufacturing a flexible substrate, depending on the pattern of the fixed region 301. That is, it contributes to correction of distortion and warpage of the fragile flexible base material. Thereby, even a thin flexible substrate having no backing can suppress warping and distortion, and the accuracy of a desired process can be improved.

  FIG. 5 is a schematic view showing a main part of a flexible base guide rail according to the fourth embodiment of the present invention. The main part of the metal member 40 is the same as the guide rail 15 used in FIG. That is, it is processed so as to surround the lower surface of the flexible substrate 13 and the side portion and a part of the upper surface connected to the side portion with a slight separation distance. Overall, the metal member 40 may be made of stainless steel or steel in addition to aluminum. The metal member 40 includes a main guide rail member 401 and a support member 402. In the inverted U-shape of the support member 402, the main guide rail member 401 is welded or bonded to the upper plate surface 402A, and the longitudinal plate surface 402B reveals accuracy and strength in the longitudinal direction.

  The metal member 40 is a fixing region H for fixing only the vertical plate surface 402B of the support member 402 to other members. As a result, the fixing region H is arranged in a region between the support member 402 before and after processing the flexible base material 13. That is, in FIG. 1, the fixed region H is configured to be fitted onto the die plate 121 in the lower mold 12. In addition to fitting, the use of screwing not shown is also conceivable. Since the fixed region H is composed of only the vertical plate surface 402B and becomes a large space, the fixed region H tends to be a pattern that does not hinder the processing on the flexible base material 13.

  Also in the structure of the said embodiment, the metal member 40 comprises a flexible base material guide rail. Depending on the pattern of the fixed region H in the support member 402 of the metal member 40, it can be used in any process or apparatus for manufacturing a flexible substrate. Since the fixed region H has only the vertical plate surface 402B, the fixed region H tends to be a pattern that does not hinder the processing on the flexible substrate 13. The main guide rail member 401 contributes to correction of distortion and warping of the fragile flexible base material. Thereby, even a thin flexible substrate having no backing can suppress warping and distortion, and the accuracy of a desired process can be improved.

  As described above, according to the present invention, the guide rail for the flexible substrate is provided on the mold. The guide rail extends between the upper die and the lower die in the front and rear in the feeding direction of the flexible base material so as to surround a part of the flexible base material with a slight gap. The guide rail contributes to correction of distortion and warpage of a fragile flexible base material without a backing. The guide rail has a function of reinforcing the flexible base material around the pressing operation. Thereby, when performing continuous punching with a mold, warping and distortion due to the weakness of the flexible base material are suppressed, and punching accuracy is improved. Moreover, the guide rail for flexible substrates can be used in any process or apparatus for manufacturing a flexible substrate. As a result, it is possible to provide a flexible base material punching device and a flexible base material guide rail that eliminates the consumption member punched with the manufacture of the flexible substrate and suppresses distortion of the flexible base material and improves the punching accuracy.

  The present invention is not limited to the above-described embodiments and methods, and various modifications and applications can be implemented without departing from the spirit of the present invention.
