  The present invention relates to a processing apparatus and a printed circuit board production method for performing processing such as perforation on a sheet-like or plate-like workpiece having a plurality of parts to be processed.

Conventionally, when punching a hole of a predetermined shape in a sheet-like workpiece such as a flexible substrate, a die having a hole formed in the upper surface, and a punch that can be moved up and down relative to the die and inserted into the hole of the die A perforating apparatus having a mold made of the above is used. A workpiece to be punched by such a punching device is provided with a punched portion indicating a punching position, and the punch is lowered by lowering the punch in a state where the punched portion and the hole are aligned. (For example, refer to Patent Document 1).
Japanese Patent No. 3204236

  However, since the above-described punching device is provided with only one die, there is a problem that it takes a long time for the punching process when the number of punched portions formed on the workpiece is large. In addition, a drilling apparatus has been developed that can provide a plurality of molds and can simultaneously drill a plurality of drilled parts. However, such a conventional drilling device is configured to perform drilling of a workpiece formed with a plurality of identical patterns in which a plurality of drilled portions are arranged at regular intervals, and a large number of drilled holes irregularly. There is a problem that drilling of a workpiece formed with a portion cannot be performed.

  The present invention has been made to cope with the above-described problems, and an object of the present invention is to provide a processing apparatus and a printed circuit board production method capable of efficiently performing a predetermined process on a work on which a plurality of processed parts are formed. Is to provide.

In order to achieve the above-described object, a structural feature of the processing apparatus according to the present invention is that a vertical frame having a workpiece insertion hole that is movably installed on the upper surface of the base and extends in the X-axis direction and extends in the Y-axis direction. A pair of mounting members, a fixing portion for fixing a sheet-like or plate-like workpiece having a plurality of processed parts passing through the workpiece insertion holes of the pair of mounting members, and an upper center of the mounting member. Processing information on a plurality of processing parts, and a plurality of processing parts supported by both sides in the longitudinal direction of the mounting member, and a die having a punch and a die installed in the lower center of the mounting member. Input device for input, the time required for each processing unit of the plurality of processing units input to the input device to process the printed circuit board, and the length of the path when each processing unit processes the printed circuit board Or of each part to be processed Calculates the respective movement path of the processing unit of the multiple by homogenizing the, according to the calculation result, independently movement control processes the portion to be processed of the workpiece while moving a plurality of processing units to With the device.

  In the processing apparatus configured as described above, a workpiece is fixed by a fixing unit, and each processing unit performs processing on a predetermined processing target portion of the workpiece while moving a plurality of processing units independently with respect to the workpiece. I am doing so. At that time, from the processing information related to the plurality of processed parts provided in the workpiece, the moving path is calculated so that each processing part moves optimally to process the processed part. I have to. Therefore, efficient processing can be performed on the workpiece, and high-speed and high-precision processing can be realized.

  Further, the plurality of processing parts provided on the workpiece are not limited to those regularly arranged with a constant interval, and may be a plurality of parts provided irregularly. In the processing apparatus according to the present invention, even when the processing target units are irregularly arranged, the optimal movement path of each processing unit is calculated from the processing information related to each processing target unit, and each processing unit is determined according to the calculation result. Can move properly. In addition, the optimum movement route calculated by the movement control device can be obtained based on various routes. For example, the time required for each processing unit to process the processing target, the length of the path when each processing unit performs processing on the processing target, the number of processing of the processing target by each processing unit, etc. can be used. A case where the processing of each processing unit is uniform is obtained as an optimal movement path.

  Further, another structural feature of the processing apparatus according to the present invention is that a position detection device that moves together with the processing unit is provided in the vicinity of the processing unit, and processing is performed based on the position of the processing target detected by the position detection device. This is because the part has moved to process the workpiece. In this case, a camera, a sensor, or the like can be used as the position detection device. According to this, processing by the processing unit can be performed after the position of the processing target portion is accurately detected by the position detection device. For this reason, position shift does not occur between the processing target part and the part where the processing part actually performs processing, and high-precision processing becomes possible.

Further, the processing equipment according to the present invention, the processing unit, attached to the base via a vertical frame-shaped attachment member is formed to extend in the moving direction, and the processing unit is placed in the center portion of the attachment member Tei Ru. According to this, the processing unit is attached to the mounting member that is movably installed on the base, and both side portions of the mounting member extend on both sides along the moving direction of the processing unit. Since both side portions of the mounting member act as projections for preventing vibration, when the processing unit is moved together with the mounting member to perform a predetermined process on the workpiece, the processing unit is less likely to vibrate. . For this reason, accurate processing can be performed on the workpiece.

  Further, still another structural feature of the processing apparatus according to the present invention is to detect that a plurality of processing units or a plurality of processing units are attached to each other and move toward the base, respectively. When the proximity detection device detects that the processing units have approached each other, the processing units are prevented from approaching further by the control of the movement control device. According to this, it is possible to prevent the processing units or members supporting the processing unit from colliding with each other and being damaged, or interfering with each other to deteriorate the processing accuracy.

Further, the processing equipment according to the present invention, the processing unit is constituted by a mold having a punch and a die. According to this, a work can be fixed between a die provided with a hole and a punch, and punching can be performed by bringing the die and the punch close to each other and inserting the punch into the hole.

A structural feature of the printed circuit board production method according to the present invention is that a pair of vertical frame-shaped attachments having a workpiece insertion hole that is movably installed on the upper surface of the base and extends in the X-axis direction and extends in the Y-axis direction. A fixing part for fixing a member, a sheet-like or plate-like printed circuit board having a plurality of processed parts passing through the workpiece insertion holes of the pair of attachment members, and a punch installed at the upper center of the attachment member, A plurality of processing units configured by a die having a die installed at the lower center of the mounting member and supported on both sides in the longitudinal direction of the mounting member, and operations of the plurality of processing units based on predetermined processing information A printed circuit board production method for performing processing on a printed circuit board using a processing apparatus including a movement control device for controlling the process, and a fixing process for fixing the printed circuit board, and processing information on a plurality of processing parts Input process to input , A movement route calculation step for calculating each movement route of the plurality of processing units from the processing information input in the input step, and a plurality of processing units independently according to the result calculated in the movement route calculation step A processing step of performing processing on the processing target portion of the printed circuit board while moving, and calculating the movement path in the movement path calculation step, the time required for each processing unit of the plurality of processing units to process the printed circuit board, This is done by equalizing the length of the path when each processing unit performs processing on the printed circuit board, or the number of processing target units that each processing unit performs processing.

  According to this, the process with respect to a printed circuit board can be performed efficiently. In this case, the processing performed by the processing unit on the printed circuit board can be perforation or continuity inspection. Further, the calculation of the movement path in the movement path calculation step is the time required for each processing unit of the plurality of processing units to process the printed circuit board, the length of the path when each processing unit processes the printed circuit board, Or it can carry out by equalizing the number of to-be-processed parts which each process part processes. According to this, if the processing apparatus has two processing units, the total processing time, the number of processes by one processing unit, and the processing by one processing unit are much larger than when one processing unit is provided. The required travel distance can be shortened or reduced. Furthermore, if the processing apparatus includes three or more processing units, more efficient processing is possible.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 3 show a perforation apparatus M as a processing apparatus according to the present invention. The perforating apparatus M includes a base 10 installed on the floor surface F, an apparatus main body 20 provided on the upper part of the base 10, and the like. On the upper surface of the base 10, a pair of X-axis rails 11 a and 11 b extending in the X-axis direction (the left-right direction in FIGS. 1 and 2) are installed in parallel with a distance therebetween. Then, on the X-axis rails 11a and 11b, two moving support bases 12a and 12b each having a longer Y-axis direction (a direction perpendicular to the X-axis on the horizontal plane) are respectively spanned, and the X-axis rail 11a , 11b.

  In addition, screw shafts 13a and 13b are installed between the X-axis rails 11a and 11b in parallel with the X-axis rails 11a and 11b. An X-axis motor 14a for rotating the screw shaft 13a in the direction around the axis is connected to the right end portion of the screw shaft 13a in FIGS. 1 and 2, and the left end portion of the screw shaft 13b in FIGS. Further, an X-axis motor 14b for rotating the screw shaft 13b in the direction around the axis is coupled.

  The movement support base 12a is connected to a screw shaft 13a that rotates by driving of the X-axis motor 14a, and from the left end of the X-axis rails 11a and 11b in FIG. 1 before the movement support base 12b by driving of the X-axis motor 14a. It moves along the X-axis rails 11a and 11b between the side portions. The movement support base 12b is connected to a screw shaft 13b that is rotated by driving of the X-axis motor 14b, and extends from the right end of the X-axis rails 11a and 11b in FIG. 1 to the front side portion of the movement support base 12a. The X-axis motor 14b is driven to move along the X-axis rails 11a and 11b.

  In addition, rotation support shafts 15a and 15b are attached to the left and right wall portions of the base 10 via support members 15, respectively, and extension rollers 16a and 16b are attached above the rotation support shafts 15a and 15b, respectively. It has been. For this reason, for example, a roll-shaped workpiece W made of a flexible substrate is rotatably attached to the rotation support shaft 15a, and its tip is passed through the upper side of the extension rollers 16a and 16b, and then wound around the rotation support shaft 15b. You can make it take. In this case, the workpiece W is sequentially sent out from the rotation support shaft 15a and wound around the rotation support shaft 15b by rotating the rotation support shafts 15a and 15b. At that time, the extension rollers 16a and 16b support the work W so that an appropriate tension is applied to the work W, and position the work W above the X-axis rails 11a and 11b.

  Further, Y-axis rails 17a and 17b extending in the Y-axis direction are respectively installed on the upper surfaces of the movable support bases 12a and 12b, and a part of the apparatus main body 20 is configured on the Y-axis rails 17a and 17b. The attaching members 21a and 21b to be attached are attached so as to be movable in the Y-axis direction along the corresponding Y-axis rails 17a and 17b. That is, the Y-axis rails 17a and 17b are provided with screw shafts 18a and 18b along the longitudinal direction of the Y-axis rails 17a and 17b, and screw shafts 18a and 18b are respectively provided at the rear ends of the screw shafts 18a and 18b. Y-axis motors 19a and 19b for rotating the motor in the direction around the axis are coupled.

  The attachment member 21a is connected to a screw shaft 18a that rotates by driving of the Y-axis motor 19a, and moves along the Y-axis rail 17a by driving of the Y-axis motor 19a. The attachment member 21b is connected to a screw shaft 18b that rotates by driving of the Y-axis motor 19b, and moves along the Y-axis rail 17b by driving of the Y-axis motor 19b. Corresponding processing parts 22a and 22b are attached to the attachment members 21a and 21b, respectively, and the apparatus main body part 20 is composed of attachment members 21a and 21b, processing parts 22a and 22b, a fixing part to be described later, and the like.

  In addition, since the attachment members 21a and 21b and the processing portions 22a and 22b are composed of a pair having the same structure, the attachment member 21a and the processing portion 22a will be described below, and the attachment member 21b and the processing portion 22b will be described. Description of is omitted. As shown in FIGS. 3 and 4, the attachment member 21 a is configured by a substantially elliptical frame that is long and symmetrical in the Y-axis direction, and the attachment members 21 a and 21 b include the processing units 22 a and 22 b. As seen from above, it is supported from the left and right directions on the paper. As a result, compared with the case where only one side is supported, even during sudden acceleration and sudden stop, it is difficult to cause a positional deviation between the punches 27a and 28a and the dies 24 and 25. The inside of the mounting member 21a is formed in a slit-like workpiece insertion hole 23 that extends in the X-axis direction and extends in the Y-axis direction. When the workpiece W is to be drilled, Pass W.

  In addition, a pair of dies 24 and 25 are attached to a portion facing the work insertion hole 23 at the lower center of the attachment member 21a, and the hole 24a faces the opening upward in the die 24. A hole 25a is formed in the die 25 with the opening facing upward. An alignment hole 26 is provided between the dies 24 and 25 at the lower center of the mounting member 21a.

  In addition, rod-like punches 27a and 28a that can be inserted into the holes 24a and 25a can be lifted and lowered via the lifting mechanisms 27 and 28 at the portions corresponding to the dies 24 and 25 in the upper center of the mounting member 21a. It is attached. The punches 27a and 28a are lowered by the operation of the elevating mechanisms 27 and 28 to enter the corresponding holes 24a and 25a, respectively, and the workpiece W is punched by the shearing force at that time. The dies 24 and 25 and the punches 27a and 28a constitute a processing unit 22a made of a mold.

  Further, the holes 24a and 25a and the punches 27a and 28a corresponding to the holes 24a and 25a are set to a size capable of shearing the workpiece W when fitted. The diameters of the hole 24a and the hole 25a may be set to the same or different sizes. Similarly, the diameters of the punch 27a and the punch 28a may be the same or different. By setting these to different sizes, two types of holes can be opened by one processing unit 22a. Therefore, it is possible to open up to four types of holes having different sizes in the processing units 22a and 22b.

  In addition, in the lower part of the holes 24a and 25a in the lower center of the mounting member 21a, an accommodating portion 29 for accommodating debris of the drilled work W is formed, and the debris generated during drilling is After being accommodated in the accommodating portion 29, it is discharged to the outside by suction of a suction device (not shown). A CCD camera 30 as a position detection device of the present invention is attached to the positioning hole 26 between the punches 27a and 28a at the upper center of the attachment member 21a.

  Further, as shown in FIG. 5, a microphotosensor 31 having a recess opened toward the moving support table 12b is attached to a portion of the moving support table 12a facing the moving support table 12b. A rod-shaped dock 32 that can enter the concave portion of the micro photosensor 31 is attached to a portion facing the concave portion of the microphotosensor 31. The micro photo sensor 31 includes a light emitting unit that emits a light beam L that passes through the recess and a light receiving unit that receives the light beam L. When the dog 32 enters the recess, the light beam L is blocked and moved. It can be detected that the support table 12a and the moving support table 12b are close to each other. The micro photo sensor 31 and the dog 32 constitute an approach detection device according to the present invention.

  Further, the fixed portion is composed of four clamping claws 35 a, 35 b, 35 c, and 35 d installed near the ends of the X-axis rails 11 a and 11 b on the upper surface of the base 10. These clamping claws 35a, 35b, 35c, and 35d are each composed of a gripping part for removably fixing the edge of the workpiece W and a moving mechanism (not shown). Independently move in the X-axis direction and the Y-axis direction. As this moving mechanism, a mechanism that moves using a motor may be used, or a mechanism that moves manually may be used. When a manual moving mechanism is used, each of the holding claws 35a, 35b, 35c, and 35d can be fixed at a predetermined position with a screw. Further, the gripping portion is installed at the same height as the workpiece insertion hole 23 of the attachment member 21a, and fixes the edge portion of the workpiece W passing through the workpiece insertion hole 23 from the outside of the side edge portion.

  According to this, it becomes possible to fix various workpieces of different sizes by moving a predetermined clamping claw portion of the clamping claw portion 35a and the like. For example, the clamping claw portion 35a of the four clamping claw portions 35a is fixed as a reference point, the clamping claw portion 35d is movable along the X-axis direction, and the clamping claw portion 35b is moved along the Y-axis direction. Make it movable. The clamping claw portion 35c is movable in the X-axis direction and the Y-axis direction. Accordingly, the workpiece W of any size can be fixed within a range in which the four clamping claws 35a and the like can be moved. In addition, since the clamping claw portion 35a and the like are movable, even if the workpiece W is formed of a thin and flexible sheet, it can be fixed in a state of being pulled straight with an appropriate tension. This improves the processing accuracy.

  In addition to the above-described devices, the punching device M according to the present embodiment includes the movement control device 40 including the input device 36, the CPU 37, the ROM 38, the RAM 39, and the like shown in FIG. The input device 36 is constituted by an operation panel, and perforation information such as position (coordinates) and size (diameter) relating to each perforated part (not shown) formed on the work W and CCD according to the operation of the operator. Offset information indicating the offset between the cameras 30 and 30a and the positions of the punches 27a and 28a is transmitted to the movement control device 40.

  Further, the program shown in FIG. 7 is stored in the ROM 38 of the movement control device 40, and the CPU 37 executes the program based on the punching information input from the input device 36. That is, the movement control device 40 calculates the movement path of each processing unit 22a, 22b based on the punching information input from the input device 36. Then, based on the calculation result and the detection result of the CCD camera 30 and the CCD camera 30a attached to the attachment member 21b, the X-axis motors 14a and 14b, the Y-axis motors 19a and 19b, the lifting mechanisms 27 and 28, and the attachment The operation of the elevating mechanisms 41 and 42 attached to the member 21b is controlled.

  In the above configuration, when drilling a workpiece W, the workpiece W is first attached to the punching device M and fixed at a predetermined position, and the punching device M is turned on to be in an operable state. Then, drilling information of a plurality of drilled portions provided on the workpiece W is input by operating the input device 36. As the drilling information, a reference point where the position of each drilled part on the coordinate axis, for example, the X coordinate and the Y coordinate are both “0”, is set, and the X coordinate and Y coordinate of each drilled part with respect to the reference point are set. The value and the size of the diameter of each drilled part are used. The punching information input from the input device 36 is stored in the RAM 39 of the movement control device 40.

  When the input of drilling information is completed, a start switch (not shown) is turned on. As a result, the execution of the program shown in FIG. The program starts in step 100, and in step 102, the punching information stored in the RAM 39 is read. Next, the program proceeds to step 104. In step 104, the processing units 22a and 22b each perform a process of dividing a machining area to be drilled.

  Here, the machining area is divided based on a predetermined rule. As the predetermined rule, for example, the processing times of the processing units 22a and 22b are evenly distributed, the approximate value of the movement route is substantially equalized, and the like. Then, within the machining area divided based on these two rules, the approximate values of the movement paths are obtained so as to connect the coordinates of the drilled parts to be drilled by the respective processing units 22a and 22b. Is stored in the RAM 39. In addition, about the movement path | route at the time of process part 22a, 22b actually moving, since processes, such as smoothing, are performed, it does not necessarily move in a straight line between to-be-punched parts. For this reason, the addition of simple processing position distances is indicated by an approximate value.

  When the process in step 104 is completed, the program proceeds to step 106, where the respective movement paths of the processing units 22a and 22b are obtained, and a process for optimizing the movement path is performed. Each movement path is obtained by combining the drilled parts in the machining area, and the optimization of the movement path is based on the suppression operation, the shortest operation, the optimum speed, and the presence or absence of mutual interference between the processing units 22a and 22b. This is done by changing the route based on judgment or the like. That is, in the vibration suppression operation, the movement of the processing units 22a and 22b acts so as to cancel vibrations generated by the movement of each other, and the processing units 22a and 22b move symmetrically or longitudinally symmetrically. This can be achieved by moving in a short distance while changing the traveling direction as appropriate without moving long in one direction.

  The shortest operation is to set the movement path so that the movement distances of the processing units 22a and 22b are the shortest. The optimum speed is as high-speed processing as possible with the machining accuracy within the specified range. It is set to a speed that can be performed. Further, the determination of the presence or absence of mutual interference is to set the movement path so that the processing units 22a and 22b do not come into contact with each other when moving toward a predetermined portion to be drilled.

  Next, when the moving paths of the processing units 22a and 22b are obtained, the program proceeds to step 108, and the processing units 22a and 22b drill the corresponding drilled parts while moving along the obtained moving paths. It is determined whether or not the difference in time required for the determination is equal to or less than a predetermined value. The predetermined value is set in advance and stored in the RAM 39. Here, if the time difference is larger than the predetermined value and it is determined as “NO” in Step 108, the program proceeds to Step 104 and performs the above-described processing again. In this case, a machining area different from the machining area obtained in the previous process is set, a movement route based on another rule is obtained, and this process is repeated until the obtained movement route becomes appropriate.

  Next, in step 106, a process for obtaining the respective movement paths of the processing units 22a and 22b in the machining area set in the process of step 104 and a process for optimizing the movement path are performed. Then, in step 108, it is determined whether or not the difference between the processing times of the processing units 22a and 22b based on the obtained movement path is equal to or less than a predetermined value. The CPU 37 repeats the processes of steps 104 and 106 until the difference between the processing times of the processing units 22a and 22b becomes equal to or smaller than the predetermined value and it is determined “YES” at step 108. If the difference between the processing times of the processing units 22a and 22b becomes equal to or smaller than a predetermined value and it is determined “YES” in step 108, the program proceeds to step 110.

  In step 110, a process of determining the movement route when it is determined “YES” in step 108 as the optimum movement route of each of the processing units 22a and 22b is performed. The data of the movement route is stored in the RAM 39. In step 112, the processing units 22a and 22b move along the moving path, and the punch 27a is moved to the punching position using the offset amount between the CCD cameras 30 and 30a and the punches 27a and 28a according to the diameter of the punching. , 28a and the dies 24, 25 are moved to perform a drilling process.

  This drilling process is performed as follows. First, the X-axis motors 14a and 14b and the Y-axis motors 19a and 19b are operated to place the processing units 22a and 22b in the drilled portions that are the starting points of the respective movement paths. Then, the corresponding perforated part is photographed by the CCD cameras 30 and 30a. This image data is sent to the CPU 37, subjected to image processing, and stored in the RAM 39 as position data. Then, based on the difference between the position data of the drilled part and the position data of the holes 24a, 25a, etc., the X-axis motor 14a is operated, for example, between the hole 24a and the corresponding drilled part. Match the positions.

  Then, the punch 27a is lowered by the operation of the elevating mechanism 27 to perforate the portion to be perforated. Similarly, the processing unit 22b also punches the corresponding drilled part. When the first drilling process is completed, the processing units 22a and 22b move to the positions of the next drilled parts, respectively, and after confirming the positions of the drilled parts with the CCD cameras 30 and 30a, Perforate. Then, the processing units 22a and 22b repeat the drilling of the drilled part while sequentially moving along the movement path according to the confirmation of the position of the drilled part by the CCD cameras 30 and 30a.

  In the meantime, if the processing units 22a and 22b approach and interfere with each other, the movement control device 40 detects that the processing units 22a and 22b are detected by the detection of the approach detection device including the microphotosensor 31 and the dog 32. Control to prohibit further approach is performed. When all the drilled portions have been punched, the program proceeds to step 114 and ends.

  In this way, in this punching device M, the workpiece W is fixed, and the processing portion 22a, 22b is punched in the processing portion while moving the processing portions 22a and 22b independently of each other, so that efficient processing can be performed. At that time, since the optimum movement path of the processing units 22a and 22b is calculated from the processing information related to the processing target portion of the workpiece W, even an irregularly formed drilling portion can be efficiently drilled. And high-speed and high-precision processing can be realized. Further, since the perforation apparatus M according to the present embodiment includes the CCD cameras 30 and 30a, a positional shift does not occur between the processing target part and the hole part 24a and the like, and accurate processing is possible. .

  Furthermore, since the four clamping claws 35a and the like included in the punching device M according to the present embodiment are movable, it is possible to fix various workpieces having different sizes. Further, even a sheet made of a flexible substrate that is easily bent, such as the workpiece W, can be fixed in a state of being pulled straight with an appropriate tension. This improves the processing accuracy. Furthermore, since both side portions of the attachment member portions 21a and 21b are formed so as to protrude along the moving direction, vibrations are less likely to occur when the processing portions 22a and 22b move. For this reason, accurate processing can be performed on the workpiece W.

  In addition, the processing apparatus according to the present invention is not limited to the above-described embodiment, and can be implemented with appropriate modifications. For example, although the punching device M described above includes two processing units 22a and 22b, the number of moving mechanisms for moving the processing device and the processing device may be three or more. Further, in the vicinity of each processing unit 22a, 22b, a CCD camera capable of photographing the perforated part from an angle in addition to the CCD cameras 30, 30a can be provided. According to this, the position detection of the to-be-pierced part becomes more accurate.

  Furthermore, in the above-described embodiment, the workpiece W is a flexible substrate wound in a roll shape. However, the workpiece W may be formed of a sheet having a short length formed in a square shape or a rectangular shape. You may comprise with a thick plate-shaped thing. Moreover, it can replace with perforation and can also perform the process and cut-out for grind | polishing the contact part of a flexible substrate, for example. In the case of polishing, a polishing jig is attached in place of the processing units 22a and 22b, and in the case of clipping, a fixed cutting blade or a rotary cutting blade is attached in place of the processing units 22a and 22b. In this embodiment, both the optimization process at the time of path generation and the detection by the micro photosensor 31 and the dock 32 at the time of actual operation are checked. Interference may be prevented. Furthermore, in the above-described embodiment, the processing device is the punching device M, but this processing device may be an insertion inspection device for performing a continuity inspection of the workpiece W. Instead of the processing units 22a and 22b for drilling, a processing unit for continuity inspection is used.
