Description

  The present invention relates to a perforating apparatus.

  For punching a sheet-like workpiece used for forming a flexible printed circuit board, the sheet-like workpiece is interposed between a punch die and a die die, and the punch of the punch die is inserted into a die die. This is done by fitting into the die hole of the mold.

  Conventionally, for example, such a perforating apparatus as shown in FIG. 13 is used (see, for example, Patent Document 1). FIG. 13 is a view for explaining a conventional perforating apparatus. In the following description, three directions orthogonal to each other are respectively in the x-axis direction (parallel to the paper surface in FIG. 13 and the left-right direction), the y-axis direction (direction perpendicular to the paper surface in FIG. 13), and the z-axis direction (FIG. 13 in a direction parallel to the paper surface and perpendicular to the x-axis).

As shown in FIG. 13, the punching device 1 includes a feeding mechanism 10, a winding mechanism 11, a punching mechanism 20, a feeding mechanism 30, and a pair of tension mechanisms 40 and 42. In this punching device 1, punching of the sheet-like workpiece W is performed as follows.
First, the sheet-like workpiece W is moved by a predetermined amount by the synchronous operation of the feeding mechanism 10, the winding mechanism 11, and the feeding mechanism 30 in a state where punching can be performed. Thereafter, the tension mechanisms 40 and 42 are operated synchronously in a state in which the feeding mechanism 10 operates with the rewinding function, and tensions in the x-axis direction and the y-axis direction are applied to the workpiece W. Thereafter, the punching mechanism 20 is appropriately moved in the x-axis direction and the y-axis direction so as to punch a hole in the punched portion of the sheet-like workpiece W in a predetermined drilling pattern. In this way, drilling is performed on the sheet-like workpiece W.

JP 2001-341097 A (FIG. 1)

  By using such a punching device, it is possible to perform punching well on a sheet-like workpiece, but in order to punch a strip-like workpiece, a strip-like workpiece It is necessary to perform drilling with both ends of the object clamped by a clamper. However, when both ends of the strip-shaped workpiece are clamped by the clamper, the clamper is in the way so that it is not possible to drill at both ends of the strip-shaped workpiece. There was a problem that drilling could not be performed over the entire surface of the object.

  In such a case, the first drilling operation is performed in a state in which only one end of the strip-shaped workpiece is clamped by the clamper, and then only one end on the side where the drilling is performed is clamped. If the second drilling operation is performed, since it becomes possible to perform the drilling by the second drilling operation even at one end of the side where the drilling has not been performed by the first drilling operation, It is believed that drilling can be performed over the entire surface of the workpiece.

  However, in this case, since it is necessary to perform the drilling work in two steps, and it is necessary to perform the work of clamping the strip-shaped workpiece with the clamper twice, the drilling work is complicated as a whole. Therefore, there is a problem that it is not easy to increase the productivity of the drilling operation.

  Accordingly, the present invention has been made to solve such a problem, and provides a drilling apparatus capable of performing a drilling operation over the entire surface of a strip-shaped workpiece with high productivity. For the purpose.

According to the punching device described in the above (1), the position adjustment of the punching position in one direction in the strip-shaped workpiece is performed using two sets of work feeding devices having an upper roller and a lower roller. . For this reason, highly accurate position adjustment in the strip-shaped workpiece is sufficiently possible.
However, with fine pitches in recent years, even with strip-shaped workpieces, position adjustment with higher positional accuracy may be required.
Even in such a case, the position adjustment of the piercing position in one direction in the strip-shaped workpiece can be performed horizontally along the one direction as a piercing mechanism like the piercing device described in (2) above. If it is performed by using a movable drilling mechanism, the drilling mechanism can be moved with high accuracy using a screw screw or the like. Position adjustment can be performed. For this reason, it becomes possible to drill a strip-shaped workpiece with higher positional accuracy.

(3) The punching device of the present invention is a base and two sets of work feeding devices provided on the base for horizontally moving a strip-shaped workpiece as a work along one direction. A pair of workpiece feeding devices each having an upper roller and a lower roller, and the two sets of workpiece feeding devices are provided to be horizontally movable along the other direction between the two sets of workpiece feeding devices. And a drilling mechanism for performing drilling.

  For this reason, according to the punching device of the present invention, in addition to feeding a strip-shaped workpiece as a workpiece by two sets of workpiece feeding devices (advancing or retreating along one direction), the strip-shaped workpiece The workpiece can be fed by one of the two sets of workpiece feeding devices. As a result, the front end and the rear end of the strip-shaped workpiece can be sent to the drilling position in a free state by either the front end portion or the rear end portion of the strip-shaped workpiece. It becomes possible to perform perforation well at any end of the end.

In addition, since the front end portion and the rear end portion of the strip-shaped workpiece can be sent to the drilling position by a series of operations of the two sets of workpiece feeding devices, it is necessary to perform the drilling operation in two steps. Disappear.
Furthermore, since the strip-shaped workpiece can be gripped by the upper roller and the lower roller, the operation of clamping the strip-shaped workpiece with the clamper becomes unnecessary.

  For this reason, the punching device of the present invention is a punching device capable of performing a punching operation over the entire surface of the strip-shaped workpiece and with high productivity, and the object of the present invention is achieved.

  In the punching apparatus of the present invention, the position adjustment of the punching position in the other direction of the strip-shaped workpiece can be performed by appropriately moving the punching mechanism along the other direction.

(4) In the punching device according to (3), it is preferable that the punching mechanism is further movable horizontally along one direction.

According to the punching device described in the above (3), the position adjustment of the punching position in one direction in the strip-shaped workpiece is performed using two sets of work feeding devices having an upper roller and a lower roller. . For this reason, highly accurate position adjustment in the strip-shaped workpiece is sufficiently possible.
However, with fine pitches in recent years, even with strip-shaped workpieces, position adjustment with higher positional accuracy may be required.
Even in such a case, the position adjustment of the piercing position in one direction in the strip-shaped workpiece is adjusted horizontally along the other direction as a piercing mechanism like the piercing device described in (4) above. If it is performed by using a drilling mechanism that is not only movable but also horizontally movable in one direction, the drilling mechanism can be moved with high accuracy using a screw screw or the like. In addition, it is possible to adjust the position of the strip-shaped workpiece with higher positional accuracy. For this reason, it becomes possible to drill a strip-shaped workpiece with higher positional accuracy.

(5) In the punching device according to any one of (1) to (4), a work guide surface for smoothly moving the strip-shaped workpiece is provided around the punching mechanism. It is preferable.

When the strip-shaped workpiece is rigid, the above-described work guide surface is not always necessary. However, when the strip-shaped workpiece is flexible, when the strip-shaped workpiece is fed by one of the two workpiece feeding devices, both ends of the strip-shaped workpiece in the other direction. Warping and undulation may occur in the strip-shaped workpiece due to the portion or one end portion in one direction depending on gravity. Even in such a case, it is possible to effectively suppress the occurrence of warpage and waviness of the strip-shaped workpiece by providing the work guide surface as in the punching device described in (5) above. This makes it possible to smoothly feed strip-shaped workpieces.
In this case, the height of the upper surface of the work guide surface is preferably set at a position slightly higher (for example, about 0.050 mm to 2.0 mm) than the height of the upper surface of the die mold.

(6) In the punching device according to any one of (1) to (5), the interval between the two sets of work feeding devices is set to be shorter than the length along one direction of the strip-shaped workpiece. It is preferable that

By configuring in this way, the strip-shaped workpiece is always fed by at least one of the two sets of workpiece feeding devices, and reliable workpiece feeding is realized.
In this case, the interval between the two sets of work feeding devices is preferably about 50 mm to 150 mm, although it depends on the size of the strip-shaped workpiece and the size of the punching mechanism.

(7) In the punching device according to any one of (1) to (6), between the first workpiece feeding device on the workpiece standby position side of the two sets of workpiece feeding devices and the punching mechanism. It is preferable to further include a workpiece tip end detection device arranged.

With this configuration, the punching device can accurately know the position of the strip-shaped workpiece in one direction prior to punching, and enables subsequent accurate drilling.
In the initial state, the workpiece leading end detection device prevents the strip-shaped workpiece from moving forward, and outputs a detection signal and detects the strip-shaped workpiece when the leading end of the strip-shaped workpiece is detected. A stopper configured to allow advancement of the workpiece can be preferably used.

(8) In the punching device according to any one of (1) to (7), the strip-shaped workpiece is moved from the workpiece standby position to the workpiece standby position side of the two sets of workpiece feeders. It is preferable to further include a workpiece transfer device that transfers the workpiece toward the one workpiece feeding device.

With this configuration, the strip-like workpiece can be automatically conveyed to the first workpiece feeder simply by supplying the strip-like workpiece to the workpiece standby position. Productivity is improved.
In this case, the supply of the strip-shaped workpiece to the workpiece standby position can be performed manually or by a suction pad described later.

(9) In the punching device according to any one of (1) to (8), a suction pad that transports a strip-shaped workpiece before punching from the workpiece loading position toward the workpiece standby position, and punching It is preferable to further include a suction pad for transporting the strip-shaped workpiece after processing from the workpiece standby position toward the workpiece unloading position.

  By comprising in this way, a strip-shaped workpiece can be supplied only by supplying the strip-shaped workpiece before a punching process to a workpiece carrying-in position. In addition, the strip-shaped workpiece can be recovered simply by recovering the strip-shaped workpiece after perforation processing from the workpiece carry-out position. For this reason, the productivity of the overall drilling operation is improved.

(10) In the punching device according to any one of (1) to (9), the punching mechanism may be a punching mechanism having a punching die including a punching die and a die die. preferable.

  In the punching apparatus of the present invention, it is of course possible to use a punching mechanism using a laser or a drill as the punching mechanism, but as the punching mechanism, a punching die comprising a punching die and a die die is used. It is preferable to use a drilling mechanism having With this configuration, the time required for the drilling process can be greatly shortened, and the productivity of the drilling work is improved.

(11) In the punching apparatus according to (10), it is preferable that the punching mechanism performs punching without a guide pin between the punch die and the die die.

  By configuring in this way, it becomes possible to place a strip-shaped workpiece having a large area between the punching die and the die die, so that the strip-shaped workpiece having a large area is placed. Can be perforated.

(12) In the punching device according to (10) or (11), it is preferable that the punch die further includes a stripper plate.

  With this configuration, it is possible to prevent the strip-shaped workpiece from adhering to the punch of the punching die after the punching operation, so that the productivity of the punching operation is improved.

(13) In the punching device according to the above (10) or (11), the punching mechanism is configured such that a gap between the punch die and the die die is a thickness of a strip-shaped workpiece. It is also preferable to carry out the drilling in a large state.

With this configuration, the stripper plate can be eliminated, so that the number of parts can be reduced, the cost can be reduced, and the mold structure can be simplified.
Moreover, since the strip-shaped workpiece is carried out in a non-pressed state, the occurrence of damage to the strip-shaped workpiece can be suppressed and the reliability in quality can be improved.
Furthermore, since the punching is performed in a state where the gap between the punching die and the die die is larger than the thickness of the strip-shaped workpiece, the punching die itself needs to be raised and lowered during the punching. Since only the punch needs to move up and down, it is easy to speed up the drilling.

In this case, it is preferable that perforation is performed in a state where the gap between the punch mold and the die mold is 0.10 mm to 5.0 mm.
Here, the reason why the gap is set to 0.10 mm or more is that if the gap is less than 0.10 mm, a relatively thick workpiece may not be drilled. From this point of view, the gap is more preferably 0.20 mm or more, and further preferably 0.30 mm or more. The reason why the gap is set to 5.0 mm or less is that if the gap exceeds 5.0 mm, it is not easy to ensure the positional accuracy between the tip of the punch and the die hole. In addition, it is not easy to maintain the straightness of the punch when drilling. From this point of view, the gap is more preferably 3.0 mm or less, and further preferably 2.0 mm or less.

With this configuration, the punching position can be read in the plane of the punching die and the die die by the imaging device. For this reason, it is possible to shorten the horizontal movement time from the reading of the drilling position by the image sensor to the arrival of the drilling position of the punching mold, and the productivity of the drilling work as a whole can be improved.
In this case, if the photographing with the image sensor is performed through the die hole in the die mold, it is possible to perform the drilling as it is at the reading position of the drilling position by the image sensor, thereby further improving the productivity of the drilling work. it can. Further, in this case, since the reading of the punching position can be performed from the direction perpendicular to the strip-shaped workpiece, the reading accuracy can be improved.

(15) In the punching device according to (14), the punch mold and the die mold, in which the imaging element is not disposed, are disposed on the strip-shaped workpiece side. It is preferable that an opening housing hole for illumination is provided, and the light emitting element is disposed in the housing hole.

  By comprising in this way, the illumination light from a light emitting element is effectively utilized for illumination of a strip-shaped workpiece. And the reading of a punching position is performed effectively, when the light which permeate | transmitted the strip-shaped workpiece is read by an image pick-up element.

(16) In the punching device according to any one of (10) to (15), the punching die is at least two for aligning the punch die and the die die. Preferably, each of the punching die and the die die has at least two positioning pin holes arranged so that the at least two positioning pins are inserted therein.

  With this configuration, the punching die and the die die are attached to the punching device in a state where the punching die and the die die are accurately positioned using the positioning pin, and then the positioning pin is attached to the punching die. By punching from the positioning pin hole or the positioning pin hole of the die mold, the punching mold can be drilled accurately and easily while maintaining the exact positional relationship between the punch mold and the die mold. Can be attached to the device.

(17) In the punching device according to (16), the punching die is positioned in the positioning pin hole of the punch die and / or in the positioning pin hole of the die die. It is preferable to further have a positioning pin operator for moving the pin.

  With this configuration, it is possible to quickly perform operations for removing the punching die from the punching device and attaching a new punching die to the punching device.

(18) In the punching device according to (3) or (4), a feeding mechanism for feeding a roll-shaped workpiece as a workpiece into a sheet shape, and winding the sheet-shaped workpiece into a roll shape It is preferable to further include a winding mechanism for taking.

  By comprising in this way, not only a strip-shaped workpiece but a roll-shaped workpiece can be drilled, and a highly versatile drilling device is obtained.

For this reason, these processes are demonstrated along process order.

1. Step of supplying workpiece to workpiece standby position Strip-like workpiece W before drilling, which is placed at workpiece loading position A, is supplied to workpiece standby position B by suction pad 520 (FIG. 5A )reference.).

2. Process of Conveying Workpiece toward First Work Feeder The strip-shaped work W placed at the work standby position B is moved along one direction (y-axis direction) by the belt 510 of the work conveyance apparatus 500. And move toward the first work feeding device 310 (see FIG. 5B). At this time, the strip-shaped workpiece W is smoothly fed by the workpiece guide surface 480 provided around the workpiece conveyance device 500.

3. Step of feeding workpiece to punching position When the leading end of the strip-like workpiece W sent by the workpiece transfer device 500 hits the stopper 330 (see FIG. 5C), the stopper 330 generates a detection signal. While outputting to the control part (not shown) of the punching apparatus 100, it moves below so that the strip-shaped workpiece W can advance (refer Fig.7 (a)). Accordingly, the punching device 100 can accurately know the position of the strip-shaped workpiece W in one direction prior to punching, and enables subsequent accurate drilling.
Then, the upper roller 312 of the first work feeding device 310 rotates downward, and the strip-shaped workpiece W is sandwiched between the lower roller 314 (see FIG. 7B). Thereafter, the strip-shaped workpiece W is further advanced along one direction (y-axis direction) by the upper roller 312 and the lower roller 314.

4). Drilling process of the workpiece When the leading end of the strip-shaped workpiece W sent by the first workpiece feeding device 310 reaches the workpiece drilling position C, the punching mechanism 400 punches the strip-shaped workpiece W. Is done. (Refer to FIG. 6D and FIG. 6E.) At this time, the strip-shaped workpiece W is smoothly smoothed by the work guide surfaces 480, 482, 484, and 486 provided around the punching mechanism 400. Sent.

The position adjustment of the piercing position in one direction (y-axis direction) in the strip-shaped workpiece W is performed by the feeding operation of the first workpiece feeding device 310 and / or the second workpiece feeding device 320 and the movement of the piercing mechanism 400. Done. Further, the position adjustment of the punching position in the other direction (x-axis direction) is performed by moving the table 200 along the other direction (x-axis direction).
The drilling is performed in a state where no guide pin exists between the punch die 420 and the die die 440.

When drilling the rear end portion of the strip-shaped workpiece W, first, the strip-shaped workpiece W is further advanced by the first workpiece feeding device 310 and the second workpiece feeding device 320 is moved forward. The strip-shaped workpiece W is sandwiched between the upper roller 322 and the lower roller 324. At this time, the gripping of the strip-shaped workpiece W by the first workpiece feeding device 320 is released (see FIG. 7C).
Then, the strip-shaped workpiece W is further advanced along one direction (y-axis direction) by the upper roller 322 and the lower roller 324. When the rear end portion of the strip-shaped workpiece W reaches the workpiece punching position C, the punching mechanism 400 performs drilling of the rear end portion of the strip-shaped workpiece W (FIGS. 6 (f) and 7). (See (d).)

5. Step of Conveying Workpiece to Work Standby Position When the punching of the strip-shaped workpiece W is finished, the strip-shaped workpiece W is moved by the feeding operation of the second workpiece feeding device 320 and the first workpiece feeding device 310. Retreat along one direction (y-axis direction). Thereafter, the strip-shaped workpiece W is further retracted to the workpiece standby position B by the conveying operation of the workpiece conveying device 500.

6). Step of collecting workpiece from workpiece standby position The strip-like workpiece W retracted to the workpiece standby position B is moved to the workpiece unloading position D by the suction pad 540.
The punching operation is performed on the strip-shaped workpiece W by the above steps.

  For this reason, according to the punching device 100 according to the first embodiment, the strip-shaped workpiece W is fed by the first workpiece feeding device 310 and the second workpiece feeding device 320 (advanced or retracted along one direction). In addition, the strip-shaped workpiece W can be fed by either one of the first workpiece feeder 310 and the second workpiece feeder 320. As a result, since the front end and the rear end of the strip-shaped workpiece W can be sent to the drilling position in a free state, the front end of the strip-shaped workpiece W In addition, it is possible to perform the perforation well at any end portion of the rear end portion.

Further, since the front end portion and the rear end portion of the strip-shaped workpiece W can be sent to the punching position by a series of operations of the first workpiece feeding device 310 and the second workpiece feeding device 320, the drilling operation is performed. There is no need to do this in two steps.
Furthermore, since the strip-shaped workpiece W can be gripped by the upper rollers 312, 322 and the lower rollers 314, 324, the operation of clamping the strip-shaped workpiece W with a clamper becomes unnecessary.

FIG. 10 is a schematic diagram for explaining the movement of the workpiece in the drilling device according to the second embodiment.
As shown in FIG. 10, the punching device 102 (not shown) according to the second embodiment is different from the punching device 100 according to the first embodiment, and includes a first workpiece feeding device 310, a second workpiece feeding device 320, and a workpiece. The transport device 500 is not placed on the table 200 that is movable in the other direction (x-axis direction) but directly placed on the base 110 (not shown). For this reason, in the punching device 102 according to the second embodiment, in order to move the strip-shaped workpiece W relative to the punching mechanism 402 along the other direction (x-axis direction), the punching mechanism 402 is provided. It is assumed to be movable along the other direction (x-axis direction). In addition, the work guide surface 482 among the work guide surfaces 480, 482, 484, and 486 provided around the punch mechanism 402 as the punch mechanism 402 is movable along the other direction (x-axis direction). , 484 can move along the other direction (x-axis direction) together with the drilling mechanism 402.

That is, the punching apparatus 102 according to the second embodiment is provided on the base 110 and the base 110, and 2 for horizontally moving the strip-shaped workpiece W along one direction (y-axis direction). Horizontally along the other direction (x-axis direction) between the pair of workpiece feeding devices (the first workpiece feeding device 310 and the second workpiece feeding device 320) and the first workpiece feeding device 310 and the second workpiece feeding device 320 And a punching mechanism 402 for punching the strip-shaped workpiece W. As in the case of the first embodiment, the first work feeding device 310 has an upper roller 312 and a lower roller 314, and the second work feeding device 320 has an upper roller 322 and a lower roller 324. .
Further, the position adjustment of the piercing position in one direction (y-axis direction) in the strip-shaped workpiece W is performed by the feeding operation of the first workpiece feeding device 310 and / or the second workpiece feeding device 320 and the movement of the piercing mechanism 402.

As a result, it becomes possible to satisfactorily perforate both the front end portion and the rear end portion of the strip-shaped workpiece W.

Further, since the front end portion and the rear end portion of the strip-shaped workpiece W can be sent to the punching position by a series of operations of the first workpiece feeding device 310 and the second workpiece feeding device 320, the drilling operation is performed. There is no need to do this in two steps.
Furthermore, since the strip-shaped workpiece W can be gripped by the upper rollers 312, 322 and the lower rollers 314, 324, the operation of clamping the strip-shaped workpiece W with a clamper becomes unnecessary.

  For this reason, the punching device 102 according to the second embodiment, like the punching device 100 according to the first embodiment, “performs the punching operation over the entire surface of the strip-shaped workpiece and with high productivity. It becomes a drilling device that can.

Positioning of the die mounting portion (not shown) and the die mold 450 can be performed with high accuracy.
Accordingly, since the positional accuracy of the punching die 414 in the punching mechanism 404 is increased, the accuracy of the punching position in the strip-shaped workpiece W can be increased. Further, since the positional accuracy between the punch mold 430 and the die mold 450 is increased, it is possible to perform clean drilling without returning the section. Further, there is no need for a dedicated punching die position adjusting device, and the cost of the punching device can be reduced.

  As described above, in the punching device 104 according to the third embodiment, the configuration of the punching mechanism is different from that of the punching device 100 according to the first embodiment, but in other points, the punching device according to the first embodiment. Since the configuration is the same as that of the apparatus 100, the effect of the perforating apparatus 100 according to the first embodiment is directly maintained.
