Background art

[0002] In the punching of a sheet-like workpiece used for forming a flexible printed circuit board or the like, a sheet-like workpiece is interposed between a punching die and a die die, and the punch of the punching die is pressed. This is performed by fitting into a die hole of a die for a die.

[0003] Conventionally, a punching machine of this type has been used, for example, as shown in FIG. 13 (for example, see Patent Document 1). FIG. 13 is a diagram illustrating a conventional punching machine. FIG. In the following description, three directions that are orthogonal to each other will be referred to as the X-axis direction (parallel to the paper plane in FIG. 13 and the horizontal direction), the y-axis direction (the direction perpendicular to the paper plane in FIG. 13), and the z-axis direction (FIG. 13 direction parallel to the plane of the paper and perpendicular to the X axis).

Problems to be solved by the invention

[0006] By using such a punching device, it is possible to satisfactorily punch a sheet-like workpiece. However, in order to perform drilling on a strip-shaped workpiece, it is necessary to perform drilling with both ends of the strip-shaped workpiece clamped by a clamper. However, if both ends of the strip-shaped workpiece are clamped by the clampers, the clamper becomes an obstacle and it is not possible to pierce both ends of the strip-shaped workpiece. However, there is a problem that it is not possible to perform drilling over the entire surface of the workpiece.

[0007] In such a case, the first drilling operation is performed while only one end of the strip-shaped workpiece is clamped by the clamper, and then only the one end on the side where the drilling is performed is clamped. If the second drilling operation is performed in a state where the drilling is performed, it is possible to perform the drilling in the second drilling operation even at one end on the side where the drilling is not performed in the first drilling operation. Therefore, it is considered that drilling can be performed over the entire surface of the strip-shaped workpiece.

[0008] In this case, it is necessary to perform the drilling operation in two steps while performing the clamping operation, and it is necessary to perform the operation of clamping the strip-shaped workpiece twice with the clamper. There was a problem that the drilling work became complicated as a whole, and it was not easy to increase the productivity of the drilling work.

[0009] Therefore, the present invention has been made to solve such a problem, and it is possible to perform a drilling operation over the entire surface of a strip-shaped workpiece and with high productivity. The purpose is to provide equipment.

Means for solving the problem

[0010] (1) The punching device of the present invention is a set of two workpiece feeders for horizontally moving a strip-shaped workpiece as a workpiece along a workpiece feed direction (hereinafter, referred to as one direction). Then, two sets of work feeders each having an upper roller and a lower roller, and the two sets of work feeders are placed, and the strip-shaped workpiece is horizontally moved along the other direction perpendicular to one direction. The table is provided independently of the table between the two sets of work feeders so that the table can be moved along the other direction in order to move the workpiece in the other direction. And a perforation mechanism.

[0011] For this reason, according to the punching device of the present invention, in addition to feeding the strip-shaped object to be worked as a work by two sets of work feeders (moving forward or backward along one direction), , A strip-shaped workpiece can be sent by one of the two sets of work feeders. As a result, both the front end and the rear end of the strip-shaped workpiece can be sent to the piercing position in a free state, so that the front end and the strip-shaped workpiece can be sent. It is possible to satisfactorily perforate any of the rear ends.

[0012] Furthermore, since the front end and the rear end of the strip-shaped workpiece can be sent to the punching position by a series of operations of the two sets of workpiece feeders, the drilling operation is divided into two. There is no need to do it.

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 is not required.

[0013] Therefore, the drilling device of the present invention is a drilling device capable of performing a drilling operation over the entire surface of a strip-shaped workpiece with high productivity, and the object of the present invention is achieved. .

[0014] In the punching device of the present invention, the position of the punching position in the other direction on the strip-shaped workpiece can be adjusted by appropriately moving the table along the other direction.

[0015] Here, in this specification, the "strip-shaped object to be processed" means only an object to be processed which has an elongated V shape when viewed from a plane, and also includes a square shape which is not an object. It means a substantially rectangular workpiece! / ヽ.

[0016] (2) In the perforation apparatus according to the above (1), it is preferable that the perforation mechanism is movable horizontally in one direction.

According to the punching device described in the above (1), the position of the punching position in one direction on the strip-shaped workpiece is adjusted by using two sets of workpiece feeders each having an upper roller and a lower roller. I'm going to do it. For this reason, high-precision position adjustment on the strip-shaped object to be cut is sufficiently possible.

However, with the recent trend toward fine pitch, it may be necessary to adjust the position of the strip-shaped to-be-cured material with even higher positional accuracy.

Even in such a case, the position of the drilling position in one direction on the strip-shaped workpiece is determined. If the position adjustment is performed by using a punching mechanism that can move horizontally in one direction as the punching mechanism as in the punching device described in (2) above, the drilling mechanism may be a screw screw or the like. Since it is possible to move with high accuracy by using the method, it is possible to adjust the position of the strip-shaped object to be cut with even higher position accuracy. For this reason, it is possible to pierce the strip-shaped workpiece with higher positional accuracy.

[0018] (3) The punching device of the present invention is provided with two sets of a base and a strip-shaped material to be worked, which is provided on the base and is horizontally moved along one direction as a workpiece. A work feeder comprising: two sets of work feeders each having an upper roller and a lower roller; and a pair of work feeders provided horizontally movable in the other direction between the two sets of work feeders. And a drilling mechanism for drilling a workpiece.

[0019] For this reason, according to the punching device of the present invention, in addition to feeding a strip-shaped object to be worked as a work by two sets of work feeders (moving forward or backward along one direction), However, the strip-shaped workpiece can be fed by one of the two sets of work feeders. As a result, both the front end and the rear end of the strip-shaped workpiece can be sent to the piercing position in a free state, so that the front end and the strip-shaped workpiece can be sent. It is possible to satisfactorily perforate any of the rear ends.

[0020] In addition, the front end and the rear end of the strip-shaped workpiece can be sent to the punching position by a series of operations of the two work feeding devices, so that the punching operation is divided into two. There is no need to do it.

[0021] Therefore, the drilling device of the present invention is a drilling device capable of performing a drilling operation over the entire surface of a strip-shaped workpiece with high productivity, and the object of the present invention is achieved. .

[0022] In the punching apparatus of the present invention, the position of the punching position in the other direction of the strip-shaped object to be cut can be adjusted 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 in one direction.

According to the punching device described in the above (3), the position adjustment of the punching position in one direction on the strip-shaped workpiece is performed by using two sets of workpiece feeders each having an upper roller and a lower roller. I'm going to do it. For this reason, high-precision position adjustment on the strip-shaped object to be cut is sufficiently possible.

Even in such a case, the position adjustment of the punching position in one direction on the strip-shaped workpiece can be performed horizontally along the other direction as a punching mechanism as in the punching device described in (4) above. By using a drilling mechanism that is not only movable in one direction but also horizontally in one direction, the drilling mechanism can be moved with high precision using a screw or the like. Therefore, it is possible to adjust the position of the strip-shaped workpiece with higher positional accuracy. For this reason, it is possible to pierce the strip-shaped workpiece with higher positional accuracy.

(5) In the punching device according to any one of the above (1) to (4), the periphery of the punching mechanism is used to smoothly move a strip-shaped object to be cut. It is preferable that a work guide surface is provided.

[0026] When the strip-shaped workpiece is rigid, the above-described work guide surface is not necessarily required. If the strip-shaped material to be fed is flexible while feeding, and the strip-shaped material to be fed is fed by one of the two work feeders, the strip is not A warp or undulation may occur in a strip-shaped workpiece due to the fact that both ends in the other direction or one end in one direction of the workpiece in the shape of a bar hang down due to gravity. Even in such a case, by providing the work guide surface as in the drilling device described in (5) above, it is possible to effectively suppress the occurrence of warpage or undulation of the strip-shaped workpiece. As a result, strip-shaped workpieces can be sent smoothly.

In this case, the height of the upper surface of the work guide surface is preferably set to a position slightly higher (for example, about 0.050 mm to 2. Omm) than the height of the upper surface of the die for a die. [0027] (6) In the drilling device according to any one of the above (1) to (5), the interval between the two sets of workpiece feeders is determined by a length of the strip-shaped workpiece along one direction. Is also preferably set to be short.

[0028] With this configuration, the strip-shaped object to be stripped is always sent by at least one of the two sets of work feeders, and a reliable work feed is realized. I do.

In this case, the distance between the two sets of workpiece feeders is preferably about 50 mm to 150 mm depending 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), the first work feeding device on the work standby position side of the two sets of work feeding devices and the punching mechanism may be used. It is preferable that the apparatus further includes a work tip detecting device disposed therebetween.

[0030] With such a configuration, the drilling device can accurately know the position of the strip-shaped workpiece in one direction prior to the drilling, and can perform accurate drilling thereafter. .

In the initial state, the work tip detection device prevents the advance of the strip-shaped workpiece, but outputs a detection signal and detects the strip when the tip of the strip-shaped workpiece is detected. It is preferable to use a stopper that is configured to allow the workpiece to move forward.

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

[0032] With this configuration, the strip-shaped workpiece is automatically conveyed to the first workpiece feeder only by supplying the strip-shaped workpiece to the work standby position. The productivity of the drilling operation is improved.

In this case, the supply of the strip-shaped workpiece to the work standby position can be manually performed, or can be performed by using a suction node or the like to be described later.

(9) In the punching apparatus according to any one of the above (1) to (8), the suction pad for transporting the strip-shaped workpiece before the punching process toward the workpiece standby position and the workpiece standby position. When, It is preferable to further include a suction pad for transporting the strip-shaped workpiece after the perforation process toward the workpiece standby position and the workpiece unloading position.

[0034] With this configuration, it is possible to supply the strip-shaped workpiece only by supplying the strip-shaped workpiece before the drilling to the work loading position. Further, the strip-shaped workpiece can be collected only by collecting the strip-shaped workpiece after the punching process from the work discharge position. Therefore, the productivity of the drilling work as a whole is improved.

(10) In the punching apparatus according to any one of the above (1) to (9), the punching mechanism is a punching mechanism having a punching die and a die for punching. It is preferable that there is.

In the punching apparatus of the present invention, it is of course possible to use a punching mechanism using, for example, a laser or a drill as the punching mechanism, but the punching mechanism is a punch die and a die die force. It is preferable to use a punching mechanism having a punching die. With this configuration, the time required for drilling can be significantly reduced, and the productivity of the drilling operation is improved.

(11) In the punching apparatus according to (10), the punching mechanism may perform punching in a state where no guide pin exists between the punch die and the die die. Is preferred.

[0038] With this configuration, a large-area strip-shaped workpiece can be placed between the punch die and the die mold. Drilling can be performed on the workpiece.

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

[0040] With this configuration, it is possible to prevent the strip-shaped workpiece from adhering to the punch of the punch die after the punching operation, so that the productivity of the punching operation is improved.

(13) In the punching apparatus according to the above (10) or (11), the punching mechanism may be configured such that a gap between the punch die and the die die has a rectangular shape. Greater than the thickness of the object It is also preferred to carry out the drilling in the state.

[0042] With this configuration, the stripper plate can be dispensed with, so that the number of parts can be reduced, the cost can be reduced, and the mold structure can be simplified.

Further, since the strip-shaped workpiece is carried out in a non-pressed state, damage to the strip-shaped workpiece can be suppressed, and quality reliability can be improved. Furthermore, punching is performed in a state where the gap between the punch die and the die die is larger than the thickness of the strip-shaped workpiece, so that the punch die itself needs to be raised and lowered during drilling. Since it is sufficient that only the punch moves up and down, it becomes easy to speed up the drilling.

In this case, it is preferable to perform the perforation 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 set to less than 0.10 mm, there is a case where it becomes impossible to pierce a workpiece having a relatively large thickness V. From this viewpoint, the gap is more preferably 0.20 mm or more, more preferably 0.30 mm or more. The reason why the gap is set to 5.Omm or less is that if the gap exceeds 5.Omm, it is not easy to secure the positional accuracy between the tip of the punch and the die hole. Also, it is not easy to maintain the straightness of the punch at the time of drilling. From this point of view, it is more preferable to set the gap to 3.Omm or less, and it is even more preferable to set the gap to 2.Omm or less.

(14) In the punching device according to any one of the above (10) to (13), the punching die or the die die has a rectangular opening on the side of the workpiece. It is preferable that a through hole is provided for the image sensor, and an image sensor is provided in the through hole.

[0045] With this configuration, it is possible to read the punching position in the plane of the punch 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 punching position by the imaging element to the position at which the punching die reaches the punching position, and it is possible to increase the productivity of the punching operation as a whole.

In this case, the imaging by the imaging device is performed through the die hole in the die for the die. For example, since the punching can be performed at the position where the imaging element reads the punching position, the productivity of the drilling operation can be further increased. Further, in this case, since the perforation position can be read from a direction perpendicular to the strip-shaped workpiece, there is another effect that the reading accuracy can be improved.

(15) In the punching device according to the above (14), a strip-shaped workpiece to which the imaging element is not provided among the punching die and the die die is provided. It is preferable that an illumination accommodation hole is provided on the object side, and the light emitting element is arranged in the accommodation hole.

With this configuration, the illumination light of the light emitting element power is effectively used for illuminating the strip-shaped workpiece. Then, the light transmitted through the strip-shaped workpiece is read by the image sensor, so that the perforated position is effectively read.

(16) In the punching apparatus according to any one of the above (10) to (15), the punching die is used for positioning the punch die and the die die. The punch mold and the die mold each have at least two positioning pin holes arranged so that the at least two positioning pins are inserted therein. It is preferable to have.

[0049] With this configuration, the punching die and the die are accurately positioned using the positioning pins, and the punching die is attached to the punching device. By removing the positioning pin hole of the die or the positioning pin hole of the die for die, accurate and easy drilling while maintaining the exact positional relationship between the punch die and die die The tool can be attached to the punching device.

[0050] (17) In the punching device according to (16), the punching die is located in the positioning pin hole of the punch die and in Z or the positioning pin hole of the die die. It is preferable to further include a positioning pin operator for moving the positioning pin.

[0051] With this configuration, it is possible to quickly perform operations of 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 the above (3) or (4), a roll-shaped workpiece as a work is provided. It is preferable to further include an unwinding mechanism for unwinding the workpiece into a sheet and a winding mechanism for winding the sheet-like workpiece into a roll.

[0053] With this configuration, it is possible to perform punching not only on a strip-shaped object to be cured but also on a roll-shaped object to be cured. It becomes.

Then, the strip-shaped material W is further advanced in one direction (y-axis direction) by the upper roller 322 and the lower roller 324. When the rear end of the strip-shaped workpiece W reaches the workpiece punching position C, the punching mechanism 400 performs the drilling on the rear end of the strip-shaped workpiece W (FIG. 6 (f) and FIG. (See Fig. 7 (d).) ₀

[0073] 5. Process of transporting the workpiece to the work standby position

When the drilling of the strip-shaped workpiece W is completed, the strip-shaped workpiece W is retracted in one direction (y-axis direction) by the feed operation of the second workpiece feeder 320 and the first workpiece feeder 310. Let it. Thereafter, the strip-shaped workpiece W is further retracted to the workpiece standby position B by the transport operation of the workpiece transport device 500.

[0074] 6. Recovery process of the object to be removed from the work standby position

The strip-shaped workpiece W retracted to the workpiece standby position B is moved to the workpiece discharge position D by the suction pad 540.

Through the above steps, the drilling work on the strip-shaped workpiece W is performed.

For this reason, according to the punching device 100 according to the first embodiment, the strip-shaped force-cured material W is fed by the first work feed device 310 and the second work feed device 320 (along one direction). To move forward or backward), and feed the strip-shaped force-cured material W into the first workpiece feeder 310 and the first Feeding can be performed by any one of the two work feeders 320. As a result, both the front end and the rear end of the strip-shaped workpiece W can be sent to the drilling position in a free state, so that the strip-shaped workpiece W It is possible to satisfactorily perforate both the front end and the rear end.

[0076] Further, since the front end and the rear end of the strip-shaped workpiece W can be sent to the punching position by a series of operations of the first work feeder 310 and the second work feeder 320, There is no need to perform the drilling work in two separate steps.

Furthermore, since the strip-shaped target object W can be grasped by the upper rollers 312, 322 and the lower rollers 314, 324, the operation of clamping the strip-shaped target object W with a clamper is unnecessary. become.

However, when the strip-shaped driven material W is flexible, the strip-shaped powered material W is fed to one of the first and second work feeders 310 and 320. When the sheet is fed by the device, the strip-shaped workpiece W is suspended by gravity at both ends in the other direction (X-axis direction) and one end in one direction (Y-axis direction). The object W may be warped or undulated (see FIG. 8 (b);). Even in such a case, by providing the park guide surfaces 480, 482, 484, and 486 as in the drilling device 100 according to the first embodiment, as shown in FIG. It is possible to effectively suppress the occurrence of warpage and undulation of the workpiece W, and it is possible to smoothly feed the strip-shaped workpiece W.

[Second Embodiment]

FIG. 10 is a schematic diagram for explaining the movement of a workpiece in the punching device according to the second embodiment.

The drilling device 102 (not shown) according to the second embodiment is different from the drilling device 100 according to the first embodiment, as shown in FIG. 10, in that the first workpiece feeding device 310, the second workpiece feeding device 320, and the workpiece The transport device 500 is directly mounted on a base 110 (not shown), instead of being mounted on a table 200 movable in the other direction (X-axis direction). For this reason, in the drilling device 102 according to the second embodiment, in order to relatively move the strip-shaped workpiece W with respect to the punching mechanism 402 in the other direction (X-axis direction), the punching mechanism 402 is used. It can move along the other direction (X-axis direction). Also, with the perforation mechanism 402 being movable in the other direction (X-axis direction), the work guide surfaces 480, 482, 484, and 486 provided around the perforation mechanism 402 are provided. , 484 are movable along the other direction (X-axis direction) together with the drilling machine 402.

[0094] That is, the punching device 102 according to the second embodiment is provided on the base 110 and the base 110, and moves the strip-shaped workpiece W horizontally in one direction (y-axis direction). Work feeders (the first work feeder 310 and the second work feeder 320), and the other direction (X-axis direction) between the first work feeder 310 and the second work feeder 320 And a piercing mechanism 402 for piercing the strip-shaped workpiece W. The first work feeder 310 has an upper roller 312 and a lower roller 314, as in the first embodiment, and the second work feeder 320 has an upper roller 322. And has a lower roller 324!

Further, the position adjustment of the punching position in one direction (y-axis direction) on the strip-shaped workpiece W is performed by the feed operation of the first work feeders 310 and Z or the second work feeder 320 and the punching mechanism 402. It is done by moving. The position adjustment of the punching position in the other direction (X-axis direction) is performed by moving the punching mechanism 402 in the other direction (X-axis direction).

As described above, the drilling device 102 according to the second embodiment includes a mechanism for relatively moving the strip-shaped workpiece W with respect to the drilling mechanism 402 in the other direction (X-axis direction). Although different from the case of the drilling device 100 according to the first embodiment, in addition to feeding the strip-shaped workpiece W by the first workpiece feed device 310 and the second workpiece feed device 320, The workpiece W can be sent by one of the first work feeder 310 and the second work feeder 320. For this reason, as in the case of the drilling device 100 according to the first embodiment, both the front end and the rear end of the strip-shaped workpiece W can be sent to the punching position in a free state. Become like As a result, it is possible to satisfactorily perforate both the front end and the rear end of the strip-shaped workpiece W.

[0096] Further, since the front end and the rear end of the strip-shaped workpiece W can be sent to the punching position by a series of operations of the first work feeder 310 and the second work feeder 320, There is no need to perform the drilling work in two separate steps.

[0097] For this reason, the drilling device 102 according to the second embodiment is similar to the drilling device 100 according to the first embodiment in that "the drilling operation is performed over the entire surface of the strip-shaped workpiece and with high productivity." The drilling device can perform the drilling.

[0098] In the punching device 102 according to the second embodiment, the punching mechanism 402 is further horizontally movable in one direction (y-axis direction).

In the drilling device according to the second embodiment, the position adjustment of the drilling position in one direction (y-axis direction) on the strip-shaped workpiece W is performed by the first work feeding device 310 and the second page By using only the feeder 320, it is of course possible to sufficiently adjust the position of the strip-shaped object to be cured W with high accuracy.

Even in such a case, the position adjustment of the drilling position in one direction (y-axis direction) on the strip-shaped workpiece W is performed by using a drilling mechanism as in the drilling device 102 according to the second embodiment. The drilling mechanism 402, which can move not only horizontally in one direction (X-axis direction) but also horizontally in one direction (Y-axis direction), can be used. Since the 402 can be moved with high precision using a screw or the like, the position of the strip-shaped workpiece W can be adjusted with even higher positional accuracy. For this reason, it is possible to pierce the strip-shaped object to be cured W with higher positional accuracy.

[0100] Since the punching device 102 according to the second embodiment has the same configuration as the punching device 100 according to the first embodiment in other respects, it has the same effect as the punching device 100 according to the first embodiment. .

Although it has basically the same configuration, the configuration of the punching mechanism is different from that of the punching device 100 according to the first embodiment.

[0102] That is, in the punching device 104 according to the third embodiment, the punching mechanism 404 (not shown).

) Is characterized in that the punching is performed in a state where the gap between the punch die 430 and the die die 450 is larger than the thickness of the strip-shaped force-cured material W.

Therefore, according to the punching device 104 of the third embodiment, the stripper plate can be omitted. As a result, the number of parts can be reduced, the cost can be reduced, and the mold structure can be simplified.

In addition, since drilling is performed while the strip-shaped workpiece W is not pressed, the strip-shaped workpiece W is not pressed. It is possible to suppress the occurrence of damage to hardware w, and to improve the reliability in quality.

Furthermore, since punching is performed in a state where the gap between the punch die 430 and the die die 450 is larger than the thickness of the strip-shaped force-cured material W, at the time of punching, the punch die 430 is removed. It is not necessary to move up and down, and only the punch 434 needs to move up and down, so that it is easy to speed up the drilling.

[0103] The punching apparatus 104 according to Embodiment 3 is configured to perform punching in a state where the gap between the punch die 430 and the die die 450 is 0.10mm-5. Omm. ing.

The positioning pin 470 is configured to move in the vertical direction by rotating the pin operator 472.

Therefore, according to the punching device 104 according to the third embodiment, the positioning and punching mechanism 404 between the punching die 430 and the die die 450 can be performed by a simple operation of moving the positioning pin 470 up and down. The positioning between the die attaching portion (not shown) and the die die 450 can be performed with high accuracy.

Accordingly, since the positional accuracy of the punching die 414 in the punching mechanism 404 is increased, it is possible to increase the accuracy of the punching position in the strip-shaped force-cured material W. Further, since the positional accuracy between the punch die 430 and the die die 450 is improved, it is possible to perform a clear perforation without returning the section. In addition, there is also an advantage that a dedicated die position adjusting device for punching becomes unnecessary, and the drilling device can be manufactured at low cost.

As described above, in the punching device 104 according to the third embodiment, the configuration of the punching mechanism is implemented. Although it is different from the case of the drilling device 100 according to the first embodiment, the other points are the same as those of the drilling device 100 according to the first embodiment, so that the effects of the drilling device 100 according to the first embodiment are directly maintained.
