Description

  The present invention relates to a punching device and a punching method for punching an insertion hole in a sheet body that is supported in a state where tension is applied.

  A mounting head disclosed in Japanese Patent No. 3228131 is known as a spherical body suction head used when a fine spherical body (conductive ball) is sucked and mounted on a substrate or the like. The mounting head includes a main body, a porous body, and a plate, and can adsorb the conductive ball to the edge of the insertion hole formed in the plate.

  A plate used for this type of spherical body suction head is manufactured by forming an insertion hole by, for example, irradiating a laser beam to a predetermined drilling position in a sheet body. In this case, in order to accurately irradiate a laser beam or the like to the drilling position, the sheet body is supported in a state in which the outer peripheral edge of the sheet body is grasped and pulled outward (a state in which tension is applied), and the sheet body in that state Is irradiated with a laser or the like. Here, for example, as shown in FIGS. 6 to 10, when the insertion holes 61 are punched one by one at a plurality of perforation positions Pp arranged in a straight line, generally, one end side of the sheet body (in FIG. The insertion holes are drilled in order from the left side to the other end side (right side in the figure).

Japanese Patent No. 3228131 (page 2-3, FIG. 2)

  However, the above-described conventional drilling method has the following problems. That is, in this type of conventional drilling method, the insertion hole is drilled while tension is applied to the sheet member. Here, the rigidity per unit area of the portion where the insertion hole is formed in the sheet body is lower than the rigidity per unit area of the portion where the insertion hole is not formed. For this reason, the amount of elongation of the sheet body due to the tension applied to the sheet body increases as the number of insertion holes per unit area increases. Therefore, in the conventional drilling method, as shown in FIGS. 7 to 10, as the drilling operation proceeds (as the number of drilled insertion holes increases), the elongation amount of the sheet body due to the tension is One end side (left side in each figure) where the work is started increases, and as a result, the intervals La, Lb, Lc between adjacent insertion holes become longer toward one end side (in this example, La> Lb> Lc). . As described above, in the conventional drilling method, due to the fact that the interval between the adjacent insertion holes differs depending on the location, the arrangement state of the respective insertion holes is different from the prescribed (designed) arrangement. There is a fear, and improvement of this point is desired.

  The present invention has been made in view of such problems, and a main object of the present invention is to provide a punching device and a punching method that can punch an insertion hole in a sheet body as specified.

The first drilling process for drilling the insertion hole is performed in any one of an arrangement order of the areas from the central part toward the outer peripheral part of the drilling range and an arrangement order of the areas from the outer peripheral part toward the central part. In It runs in each the region.

  Further, the punching device according to claim 2 is the punching device according to claim 1, wherein a plurality of sections are provided in each region, and the processing unit is provided in each section in each of the first punching processes. The second drilling process for drilling the insertion holes at all the defined drilling positions is sequentially executed for each section according to the execution order defined for each section.

  Moreover, the punching device according to claim 3 is the punching device according to claim 2, wherein the control unit executes the second punching process with any one of the sections in the region as the first order, The second punching process is sequentially executed for each partition according to the execution order in which another partition in the same region closest to the partition that has finished the second punching process is the next order.

  According to a fourth aspect of the present invention, in the perforating apparatus according to the third aspect, the control unit has the next rank closest to the section in which the second perforating process is last performed in one area. The second perforation process is executed with the section in the area as the first section in the next rank area.

  Further, the punching device according to claim 5 is the punching device according to claim 2, wherein the control unit executes the second drilling process with any one of the sections in the region as the first order, The second punching process is sequentially executed for each partition according to the execution order in which another partition in the same region that is farthest from the partition that has finished the second punching process is the next order.

  According to a sixth aspect of the present invention, in the drilling device according to the fifth aspect, the control unit is next to the section that is the farthest from the section in which the second drilling process is last performed in one area. The second perforation process is executed with the section in the area of the next order as the first section in the area of the next order.

  Moreover, the punching device according to claim 7 is the punching device according to any one of claims 2 to 6, wherein one punching position is defined in one partition, and the control unit A process of drilling the insertion hole at the drilling position is executed as the second drilling process.

  The punching method according to claim 8 supports the sheet body in a state where tension is applied to the sheet body, and includes an area provided in a central portion of the punching range in the sheet body in the state and an outer periphery of the area. A drilling method for drilling insertion holes at a plurality of drilling positions defined in one or more annular regions provided so as to surround at least one layer, wherein the drilling method includes all the drilling positions in one region. The first drilling process for drilling the insertion hole is performed in any one of an arrangement order of the areas from the central part toward the outer peripheral part of the drilling range and an arrangement order of the areas from the outer peripheral part toward the central part.

  The punching device according to claim 1 and the punching method according to claim 8, wherein the first drilling process in which the insertion holes are drilled at all the drilling positions in one region is performed from the center portion toward the outer peripheral portion of the drilling range. This is executed for each region in accordance with any one of the arrangement order of the regions and the arrangement order of the regions from the outer periphery toward the center. In this case, in the conventional configuration and method for drilling the insertion hole from the one end side to the other end side in the sheet body, the drilled insertion holes are concentrated on the one end side in the process of drilling the insertion hole. The amount of elongation on one end side (the part where the insertion hole is already formed) due to the tension applied to the sheet body is larger than the elongation on the other end side (the part where the insertion hole is not formed). The interval between the holes becomes longer toward one end side (that is, the interval between adjacent insertion holes varies). In contrast, in this drilling apparatus and drilling method, at least one annular region is provided so as to surround the central region of the drilling range, and the first drilling process is performed as described above. The region in which the insertion hole is perforated gradually expands from the center to the outer periphery of the perforation range or from the outer periphery to the center. That is, in this drilling device and drilling method, the concentration of the drilled insertion holes in the drilling process of the insertion holes can be reduced.

By predefining, it is possible to reduce the variation in the interval between adjacent insertion holes.

  Further, in the punching device according to claim 3, the second drilling process is executed with any one of the sections in the region as the first order, and another section in the same region closest to the section for which the second drilling process is finished. The second punching process is sequentially executed for each partition according to the execution order in which the partition is the next order. For this reason, according to this drilling device, by performing the second drilling process in this way, the concentration of the drilled through holes in the drilling process of the through holes can be suppressed to a lower level. Variations in the spacing between the insertion holes can be reduced. Further, according to this punching device, the punching machine necessary for drilling the insertion holes at all the drilling positions is equivalent to the section where the second drilling process is completed and the section where the second drilling process is performed next. The moving distance can be shortened sufficiently. Therefore, according to this punching device, the efficiency at the time of punching a large number of insertion holes in the sheet member can be sufficiently improved.

  Further, in the punching device according to claim 4, a section in the next rank area closest to the section where the second drilling process was last executed in one area is defined as the first rank section in the next rank area. As a result, the second punching process is executed. For this reason, according to this punching device, the punching machine necessary for executing the second punching process for the first rank section in the next area after the completion of the second punching process for all the sections in one area. As a result, the drilling efficiency of the insertion hole can be further improved.

  According to a fifth aspect of the present invention, in the perforating apparatus according to claim 5, the second perforating process is executed with any one section in the region as the first order, and the same area that is farthest from the section that has finished the second perforating process. The second punching process is sequentially executed for each partition according to the execution order in which the other partitions are in the next order. For this reason, according to this drilling device, by performing the second drilling process in this way, the concentration of the drilled through holes in the drilling process of the through holes can be suppressed to a lower level. Variations in the spacing between the insertion holes can be reduced.

  Further, in the punching device according to claim 6, the section in the next rank area that is the farthest from the section in which the second drilling process was last performed in one area is the first section in the next rank area. The second drilling process is executed as a partition. For this reason, in this drilling device, the concentration of the drilled through-holes in the drilling process of the through-holes between one region and the next-order region can be further reduced, and as a result, adjacent penetrations in the region can be suppressed. Variations in the spacing between the holes can be further reduced.

  In the punching device according to the seventh aspect, the process of punching the insertion hole at one punching position defined in one section is executed as the second punching process. For this reason, according to this punching device, the concentration of the drilled through holes in the region in the process of drilling the through holes can be further reduced.

  Hereinafter, embodiments of a perforating apparatus and a perforating method will be described with reference to the accompanying drawings.

  First, the configuration of the perforating apparatus 1 shown in FIG. 1 will be described. As shown in the figure, the punching device 1 includes a support unit 2, a punching unit 3, a storage unit 4, and a control unit 5, and punches an insertion hole 61 in a sheet body 60 to form an alignment sheet 101 shown in FIG. It is configured so that it can be manufactured. Here, the alignment sheet 101 is a component that constitutes a suction head 100 (see the same figure) for sucking a solder ball used when a solder ball (micro ball), which is a fine spherical particle, is mounted on a terminal of a substrate. And, it has a function of aligning the solder balls by attracting the solder balls to the insertion holes 61.

  The support unit 2 is configured to be able to support the sheet body 60 in a state where tension is applied to the sheet body 60. Specifically, as an example, as shown in FIG. 1, the support portion 2 includes four fixing members 21 (see also FIG. 4) that sandwich and hold the edge of the sheet body 60, and opposing fixing members 21. A drive mechanism 22 that separates them from each other is provided.

  The punching machine 3 is configured to be able to punch the insertion hole 61 in a predetermined punching range Rp (a range in which the insertion hole 61 is punched: see FIG. 3) in the sheet body. Specifically, as an example, as shown in FIG. 1, the punching machine 3 includes an output unit 31 that outputs a laser beam L and a moving mechanism 32 that moves an irradiation position of the laser beam L output from the output unit 31. And is configured. In this case, the moving mechanism 32 moves the output unit 31 in accordance with the control of the control unit 5, and is defined in advance as the respective drilling positions Pp (positions for drilling the insertion holes 61) in the first drilling sequence and the second drilling sequence described later. By irradiating the laser beam L to the position), the insertion holes 61 are perforated one by one at each perforation position Pp. Instead of the configuration and method for moving the output unit 31, a configuration and method for moving the irradiation position of the laser light L by changing the direction of the output unit 31 may be employed.

  The storage unit 4 stores first drilling order information Ds1 indicating the order of drilling positions Pp for drilling the insertion holes 61 (hereinafter also referred to as “first drilling order”), and coordinate information Dc indicating the coordinates of the drilling positions Pp. .

  The control unit 5 controls the drilling machine 3 to drill the insertion holes 61 at the respective drilling positions Pp in the first drilling sequence indicated by the first drilling sequence information Ds1 stored in the storage unit 4.

  Next, the first drilling order and the defining method for the sheet body 60 will be described. As an example, the sheet body 60 is provided with a rectangular perforation range Rp (a region in which the insertion hole 61 is perforated) at the center as shown in FIG. In addition, a rectangular center region F1 is provided in the center of the perforation range Rp, and a rectangular annular shape surrounding the outer periphery of the center region F1 in multiples (in this example, a double, at least a single example). Regions F2a and F2b (hereinafter also referred to as “annular region F2” when not distinguished from each other, and simply referred to as “region F” when not distinguished from the central region F1 and the annular region F2) are provided. Further, each region F is provided with one or a plurality of (in this example, a plurality of) sections (partitions S1 to S36 shown in FIG. 3 and hereinafter referred to as “sections S” when not distinguished). ing. In the sheet body 60, one punching position Pp is defined in one section S (that is, only one punching position Pp exists in one section S).

  When the first punching order for the sheet body 60 is defined, first, a rank is assigned to each region F. As an example, the arrangement order of the regions F from the central part to the outer peripheral part of the perforation range Rp is given as the rank of each region F. In this sheet body 60, as shown in FIG. 3, the regions F are arranged in the arrangement order of the central region F1, the annular region F2a, and the annular region F2b from the central part of the perforation range Rp toward the outer peripheral part. Therefore, the first rank is assigned to the central area F1, the second rank is assigned to the annular area F2a, and the third rank is assigned to the annular area F2b.

  Next, a rank (corresponding to the execution order) is assigned to each partition S in each region F. Specifically, first, one section S (for example, section S1 shown in FIG. 3) is selected from among the sections S in the central area F1, which is the first-order area F, and 1 is assigned to the section S1. Give the th rank. Subsequently, the second rank (next rank) is given to another section S (in this example, section S2 shown in the figure) in the central area F1 (in the same area F) farthest from the section S1. To do.

  Next, the third rank (next rank) in the other section S in the central region F1 farthest from the section S2 (the section S excluding the sections S1 and S2, for example, the section S3 shown in the figure). ). Subsequently, the fourth rank (next rank) in the other section S in the central region F1 farthest from the section S3 (the section S excluding the sections S1 to S3 and the section S4 shown in the figure). Is granted.

  In this case, in the sheet body 60, one punching position Pp is defined in one section S. For this reason, the order of the punching position Pp in the section S1, the punching position Pp in the section S2, the punching position Pp in the section S3, and the punching position Pp in the section S4 is the first drilling order in the central region F1.

  Next, among the sections S in the annular area F2a which is the area F of the second rank, the section S (the same as the section S4 (see FIG. 3) which is the last rank in the central area F1). The fifth rank (first rank in the annular region F2a) is assigned to the section S5) shown in the drawing. Subsequently, the sixth rank (next rank) is given to another section S (section S6 shown in the figure) in the annular region F2a farthest from the section S5. Similarly, the seventh to sixteenth ranks are assigned to the sections S (sections S7 to S16 shown in the figure) in the annular region F2a. Further, the order of the drilling positions Pp in the sections S5 to S16 is set as the first drilling order in the annular region F2a following the first drilling order in the central region F1 described above.

  Next, among the sections S in the annular area F2b that is the third-order area F, the section S that is farthest from the section S16 (see FIG. 3) that is the last order in the annular area F2a. The seventeenth order (first order in the annular region F2b) is assigned to the section S17 shown in the drawing. In the same manner as described above, the 18th to 36th ranks are assigned to the sections S (sections S18 to S36 shown in the figure) in the annular region F2b. Further, the order of the drilling positions Pp in the sections S17 to S36 is set as the first drilling order in the annular region F2b following the first drilling order in the annular region F2a. Thus, the first drilling order is defined. The first drilling order defined in this way is stored in the storage unit 4 as first drilling order information Ds1.

  Next, a punching method for punching the insertion hole 61 in the sheet body 60 using the punching device 1 will be described with reference to the drawings. An example in which the insertion hole 61 is drilled in a flexible rectangular sheet body 60 (see FIG. 3) formed of a resin material will be described.

  First, the sheet body 60 is supported using the support portion 2. Specifically, as shown in FIG. 4, the four edge portions of the sheet body 60 are sandwiched by the fixing member 21 of the support portion 2. Then, the drive mechanism 22 of the support part 2 is operated. At this time, the drive mechanism 22 moves the fixing member 21 so that the opposing fixing members 21 are separated from each other. Accordingly, the sheet body 60 is supported by the support portion 2 in a state where tension is applied to the sheet body 60.

  Next, an operation unit (not shown) is operated to instruct the start of the drilling process. In response to this, the control unit 5 reads the first drilling order information Ds1 and the coordinate information Dc from the storage unit 4, and then the control unit 5 identifies the first drilling order based on the first drilling order information Ds1. To do. Next, the control unit 5 controls the drilling machine 3 to drill the insertion holes 61 in the specified first drilling order. Specifically, the coordinates of the first drilling position Pp (the drilling position Pp in the section S1 shown in FIG. 3) in the first drilling order are specified based on the coordinate information Dc, and then the moving mechanism 32 is moved. By controlling, the output unit 31 is moved to a position where the laser beam L can be irradiated to the coordinates. Next, the control unit 5 controls the output unit 31 to output the laser light L. As a result, the insertion hole 61 is formed at the first drilling position Pp in the first drilling sequence. Hereinafter, the control unit 5 drills the insertion holes 61 at the respective drilling positions Pp according to the first drilling order.

  In this case, by following the above first drilling sequence, the control unit 5 performs the process of drilling the insertion holes 61 at all the drilling positions Pp in one region F (first drilling process) in the center of the drilling range Rp. This is executed for each region F according to the arrangement order of the regions F from the portion toward the outer peripheral portion of the perforation range Rp (in this example, the order of the central region F1, the annular region F2a, and the annular region F2b). Further, by following the above first drilling sequence, the control unit 5 causes the insertion holes to be drilled in all the drilling positions Pp defined in each section S in the first drilling process (second drilling process). For each partition S in the execution order, with one partition S as the first order, and another partition S in the same region F that is farthest from the partition S for which the second drilling process has been completed as the next order. Run sequentially.

  As described above, in this drilling device 1 and the drilling method, the first drilling process for drilling the insertion holes 61 at all the drilling positions Pp in one region F is performed in each region from the central portion to the outer peripheral portion of the punching range Rp. The process is executed for each region F according to the arrangement order of F. In this case, in the conventional configuration and method of drilling the insertion hole 61 from the one end side to the other end side of the sheet body 60, the drilled insertion hole 61 is formed on the one end side in the process of drilling the insertion hole 61. Because of the concentration, the amount of elongation on one end side (the portion where the insertion hole 61 has already been formed) due to the tension applied to the sheet body 60 is greater than the elongation on the other end side (the portion where the insertion hole 61 is not formed). As a result, the interval between the adjacent insertion holes 61 becomes longer toward one end side (that is, the interval between the adjacent insertion holes 61 varies). On the other hand, in this piercing device 1 and the piercing method, a central region F1 is provided at the center of the piercing range Rp, and annular regions F2a and F2b are provided in a multiple manner so as to surround the central region F1. By performing one drilling process as described above, the region in which the insertion hole 61 is drilled gradually expands from the center of the drilling range Rp toward the outer periphery. That is, in this drilling device 1 and the drilling method, the concentration of the drilled insertion holes 61 in the drilling process of the insertion holes 61 can be reduced. Therefore, according to this drilling device 1 and the drilling method, it is possible to suppress the variation in the interval between the adjacent insertion holes 61 due to the difference in the elongation amount due to the concentration of the drilled insertion holes 61 in the drilling process of the insertion holes 61. As a result, the insertion holes 61 can be drilled in the sheet body 60 in a prescribed arrangement state.

  Further, in this drilling device 1 and the drilling method, in each first drilling process, the second drilling is performed in which the insertion holes 61 are drilled at all the drilling positions Pp defined in the plurality of sections S provided in each region F. The process is sequentially executed for each partition S in accordance with the execution order defined for each partition S. Therefore, according to the drilling device 1 and the drilling method, the concentration of the drilled insertion holes 61 in the region F during the drilling process of the insertion holes 61 is small according to the distribution state of the drilling positions Pp in the region F. By predetermining an appropriate execution order so as to be suppressed, it is possible to reduce variations in the spacing between the adjacent insertion holes 61.

  Further, in the punching device 1 and the punching method, the second punching process is executed with any one of the sections S in the region F as the first order, and is farthest from the section S where the second punching process is completed. The second punching process is sequentially executed for each partition S in accordance with the execution order in which the other partitions S in the same region F are in the next order. For this reason, according to this drilling device 1 and the drilling method, by performing the second drilling process in this manner, the concentration of the drilled through holes 61 in the drilling process of the through holes 61 can be further reduced. The variation in the spacing between the adjacent insertion holes 61 in the region F can be further suppressed.

  Further, in this perforating apparatus 1 and the perforating method, in one area F, the section S in the next rank area F that is farthest from the section S in which the second drilling process was last performed is changed to the next rank area. The second punching process is executed as the first section S in F. For this reason, according to this drilling device 1 and the drilling method, the concentration of the drilled insertion holes 61 in the drilling process of the insertion holes 61 between one region F and the next-order region F is further reduced. As a result, the variation in the interval between the adjacent insertion holes 61 in the region F can be further reduced.

  Further, in the punching device 1 and the punching method, the process of punching the insertion hole 61 at one punching position Pp defined in one section S is executed as the second punching process. For this reason, according to this drilling device 1 and the drilling method, the concentration of the drilled insertion holes 61 in the region F in the drilling process of the insertion holes 61 can be further reduced.

  Next, another embodiment of the punching device and the punching method will be described. In addition, in the following description, the same code | symbol is attached | subjected about the same component as the above-mentioned punching apparatus 1 and the punching method, and the overlapping description is abbreviate | omitted. In this configuration and method, the control unit 5 drills the insertion hole 61 in accordance with the drilling sequence (hereinafter also referred to as “second drilling sequence”) defined by the method described below.

  When the second punching order is defined for the sheet body 60 described above, first, the arrangement order of the regions F from the central portion to the outer peripheral portion of the punching range Rp is given as the rank of each region F. Specifically, the first to third ranks are assigned to the central region F1, the annular region F2a, and the annular region F2b, respectively. Subsequently, a rank (corresponding to the execution order) is assigned to each partition S in each region F. First, the first rank is assigned to one section S (for example, the section S1 shown in FIG. 5) among the sections S in the central area F1, which is the first rank area F. Next, the second rank (next rank) is given to another section S (in this example, the section S2 shown in the figure) in the central area F1 (in the same area F) closest to the section S1.

  Subsequently, the third rank (next rank) is assigned to the other sections S in the central area F1 closest to the section S2 (the sections S excluding the sections S1 and S2, for example, the section S3 shown in the figure). Give. Next, the fourth rank (next rank) is assigned to the other sections S in the central region F1 closest to the section S3 (the sections S excluding the sections S1 to S3, and the section S4 shown in the figure). Further, the order of the punching position Pp in the section S1, the punching position Pp in the section S2, the punching position Pp in the section S3, and the punching position Pp in the section S4 is set as the second punching order in the central region F1.

  Subsequently, among the sections S in the annular area F2a which is the second-order area F, the section S (see FIG. 3) closest to the section S4 (see FIG. 3) which is the last order in the central area F1. The fifth rank (the first rank in the annular region F2a) is assigned to the indicated section S5). Next, the sixth rank (next rank) is given to another section S (section S6 shown in the figure) in the annular region F2a closest to the section S5. Similarly, the seventh to sixteenth ranks are assigned to the sections S (sections S7 to S16 shown in the figure) in the annular region F2a. Further, the order of the drilling positions Pp in the sections S5 to S16 is set as the second drilling order in the annular region F2a following the second drilling order in the central region F1 described above.

  Subsequently, among the sections S in the annular area F2b which is the third-order area F, the section S (see FIG. 3) closest to the section S16 (see FIG. 3) which is the last order in the annular area F2a. The 17th rank (first rank in the annular area F2b) is assigned to the section S17 shown. In the same manner as described above, the 18th to 36th ranks are assigned to the sections S (sections S18 to S36 shown in the figure) in the annular region F2b. Further, the order of the drilling positions Pp in the sections S17 to S36 is set as the second drilling order in the annular area F2b following the second drilling order in the annular area F2a. Thus, the definition of the second drilling order is completed. In this case, as shown in FIG. 5, the second drilling order is an order along a counterclockwise (counterclockwise) spiral (spiral) path. The second drilling order defined in this way is stored in the storage unit 4 as the second drilling order information Ds2. Note that the second drilling order may be defined so that the order is along a clockwise (clockwise) spiral (spiral) path. Also, the second drilling order can be defined so that the direction of rotation differs for each region F.

  Also in this configuration and method, the control unit 5 performs the process of drilling the insertion holes 61 at all the drilling positions Pp in one region F (first drilling process) by following the second drilling sequence. In order to execute each region F according to the arrangement order of each region F from the center of the range Rp to the outer periphery of the drilling range Rp, in the same manner as the above-described configuration and method of drilling the insertion hole 61 according to the first drilling sequence, Each insertion hole 61 can be drilled in the sheet body 60 in a regular arrangement state.

  Further, in this configuration and method, by following the second drilling sequence, the control unit 5 drills the insertion holes at all the drilling positions Pp defined in each section S in the first drilling process. For each partition S in the execution order in which the two punching processes are performed, with one partition S as the first order and another partition S in the same area F closest to the partition S for which the second punching process has been completed as the next order. Run sequentially. For this reason, according to this configuration and method, the insertion holes 61 are drilled at all the drilling positions Pp because the section S where the second drilling process is completed and the section S where the second drilling process is performed next are close to each other. Thus, the total movement distance for moving the output unit 31 can be sufficiently shortened. Therefore, according to this structure and method, the efficiency at the time of punching many insertion holes 61 with respect to the sheet | seat body 60 can fully be improved.

  In this configuration and method, the section S in the next rank area F that is closest to the section S in which the second punching process was last performed in one area F is set to the first rank in the next rank area F. The second drilling process is executed as the section S of the second. For this reason, in this configuration and method, the output when the second punching process for the first rank section S in the next area F is executed after the second punching process for all the sections S in one area F is completed. As a result of being able to shorten the moving distance of the part 31, the drilling efficiency of the insertion hole 61 can be further improved.

  The punching device 1 and the punching method are not limited to the above configuration and method. For example, the example in which the insertion hole 61 is drilled in the sheet body 60 in which one punching position Pp is defined in one section S (that is, only one punching position Pp exists in one section S) has been described above. A plurality of perforation positions Pp are defined in one section S (that is, a plurality of perforation positions Pp exist in one section S), and can be applied when the insertion hole 61 is perforated in the sheet body 60. . In this configuration and method, the insertion holes 61 are drilled in all the drilling positions Pp in one section S (the second drilling process is executed), and then inserted in all the drilling positions Pp in the next rank S. Hole 61 is drilled. In this case, the priority order of the punching positions Pp in one section S can be arbitrarily defined.

  In addition, the example in which the arrangement order of the regions F from the central portion of the piercing range Rp toward the outer peripheral portion is given as the rank of each region F has been described above, but conversely, from the outer peripheral portion of the piercing range Rp toward the central portion. The arrangement order of the regions F can be given as the order of the regions F. By defining in this way, the arrangement order of the regions F from the outer peripheral portion of the piercing range Rp toward the central portion of the piercing range Rp (when applied to the sheet body 60, the annular region F2b, the annular region F2a, and the central region) The first drilling process can be executed for each region F according to the order of F1.

  In addition, although the example in which drilling is performed using the laser beam L has been described above, a configuration and a method in which drilling is performed using a drill, an electron beam, or the like may be employed. In addition, the example in which only one insertion hole 61 is drilled in one drilling step has been described above. For example, a configuration in which a plurality of adjacent insertion holes 61 are drilled at once using a drill head including a plurality of drills and The method can also be adopted.

  The example in which each region F (the center region F1 and the annular regions F2a and F2b) is defined as a rectangle has been described above. However, each region F has another arbitrary shape (for example, a circle, an ellipse, or a polygon other than a rectangle). It may be specified. Moreover, about a cyclic | annular area | region, single or triple or more can be provided. In addition, the example in which the plurality of punching positions Pp are arranged in a matrix (see FIG. 3) has been described above, but the plurality of punching positions Pp may be arranged in a straight line.
