Description

Drilling device {HOLE-PUNCHING APPARATUS}

The present invention relates to a drilling device.

Perforation of the sheet-shaped workpiece to be used for forming a flexible printed board is performed by interposing the sheet-shaped workpiece between the punch die and the die die, and fitting the punch of the punch die into the die hole of the die die. Do it.

Conventionally, the thing as shown in FIG. 13 is used for this kind of punching apparatus (for example, refer patent document 1). Fig. 13 is a diagram for explaining a conventional punching device. In addition, in the following description, three directions orthogonal to each other are respectively the x-axis direction (parallel to left and right directions with respect to the ground in FIG. 13), the y-axis direction (direction perpendicular to the ground in FIG. 13), and z. It is set to the axial direction (direction parallel to the ground in FIG. 13 and orthogonal to the x-axis).

This punching device 1 includes a feeding mechanism 10, a winding mechanism 11, a drilling mechanism 20, a transfer mechanism 30, and a pair of tension mechanisms 40 and 42, as shown in FIG. Doing. In this punching device 1, punching with respect to the sheet-shaped workpiece W is performed as follows.

Thereafter, the tension mechanisms 40 and 42 are synchronously operated in the state where the feeding mechanism 10 operates in the rewinding function, thereby giving the workpiece W tension in the x-axis direction and the y-axis direction. Thereafter, the punching mechanism 20 is appropriately moved in the x-axis direction and the y-axis direction to punch in a predetermined punching pattern on the punching target portion of the sheet-shaped workpiece W. In this manner, perforation is performed on the sheet-shaped workpiece W.

Patent Document 1: Japanese Patent Application Laid-Open No. 2001-341097 (Fig. 1)

By using such a punching device, punching can be performed well on the sheet-shaped workpiece, but in order to punch the workpiece in the form of a single sheet, both ends of the single-shaped workpiece are clamped with a clamper. It is necessary to carry out perforation. By the way, when clamping both ends of the workpiece in the form of a single-shaped workpiece with the clamper, the clamper is hindered, so that drilling cannot be carried out at both ends of the workpiece in the form of a single-layer workpiece, so that drilling is performed over the entire surface of the workpiece in the form of a single workpiece. There was a problem that could not be done.

In such a case, the first punching operation is performed while clamping only one end of the single-shaped workpiece with the clamper, and then the second punching operation is performed while clamping only one end of the punched side. In this case, the punching can be performed in the second drilling operation even at one end of the side where the drilling is not performed in the first drilling operation, so that the punching can be performed over the entire surface of the workpiece in the form of a single piece. I can think of it.

In this case, however, it is necessary to divide the punching work twice and to perform the clamping work in the form of a single piece with the clamper twice, so that the punching work is complicated and the productivity of the punching work is easily increased. There was a problem not.

Then, this invention was made | formed in order to solve such a problem, and an object of this invention is to provide the perforation apparatus which can carry out a perforation operation with the whole productivity over the whole surface of the workpiece of single-shape shape, and high productivity.

(1) The punching device of the present invention is a two-piece work conveying device for horizontally moving a workpiece having a single-shape shape as a work along the work conveying direction (hereinafter referred to as one direction), each of which is an upper roller and a lower roller. Two sets of workpiece conveying apparatuses having a plurality of workpiece conveying apparatuses and movable two kinds of workpiece conveying apparatuses themselves to move horizontally along the other direction perpendicular to one direction by stacking the workpieces in the form of one piece; It is provided between a table and the said two sets of workpiece | work conveying apparatuses independently from the said table, and provided with the punching mechanism for puncturing to the workpiece of single shape.

Therefore, according to the drilling device of the present invention, two sets of single-shaped workpieces as workpieces are transferred by two sets of workpiece conveying devices (forwarding or retracting along one direction), and two single-shaped workpieces are transferred. It becomes possible to convey by any of the workpiece conveyance apparatuses of a workpiece conveyance apparatus. As a result, any of the front end and the rear end of the single-piece workpiece can be transferred to the punched position in a free state, so that the end of either the front end or the rear end of the single-shaped workpiece is free. It is possible to perforate well.

In addition, since the front end and the rear end of the single-shaped workpiece can be transferred to the punching position by a series of operations of the two sets of work conveying apparatuses, it is not necessary to divide the punching work twice.

Moreover, since the workpiece | work of a single-shape shape can be hold | maintained by an upper roller and a lower roller, the operation which clamps a single-shaped workpiece with a clamper becomes unnecessary.

For this reason, the drilling apparatus of this invention becomes a drilling apparatus which can carry out a drilling operation with the high productivity over the whole surface of the to-be-processed workpiece, and the objective of this invention is achieved.

Moreover, in the punching device of this invention, the position adjustment of the punching position of the other direction in the single-shaped workpiece can be performed by moving a table suitably along the other direction.

In this specification, the "single shaped workpiece" does not necessarily mean only an elongated shaped workpiece in plan view, but means that it is a roughly shaped workpiece including a square shape. will be.

(2) In the punching apparatus as described in said (1), it is preferable that the said drilling mechanism can move horizontally along one direction.

According to the drilling device described in the above (1), the position adjustment of the drilling position in one direction in the single-shaped workpiece is to be performed using two sets of work transfer devices having an upper roller and a lower roller. For this reason, high-precision position adjustment in the single-shaped workpiece is fully possible.

However, with the recent fine pitch, it is also conceivable that a position adjustment at a higher position accuracy is required even in a single-shaped workpiece.

Even in such a case, the position adjustment of the punching position in one direction in the single-shaped workpiece is performed by using a punching mechanism which can move horizontally along one direction as the punching mechanism as in the punching apparatus described in (2) above. In this case, the punching mechanism can be moved with high accuracy by using a screw screw or the like, so that it is possible to adjust the position of the single-shaped workpiece at higher position accuracy. For this reason, it becomes possible to perforate the workpiece of single shape with higher positional accuracy.

(3) The punching device of the present invention is provided with a base and two sets of workpiece conveying devices for horizontally moving a single-shaped workpiece as a workpiece along one direction, each of which is an upper roller and a lower part. It is provided between the two sets of workpiece conveying apparatuses which have a roller, and the said two sets of workpiece conveying apparatus so as to be movable horizontally along the other direction, and equipped with the punching mechanism for punching to a single-shaped workpiece. It features.

Therefore, according to the drilling device of the present invention, two sets of single-shaped workpieces as workpieces are transferred by two sets of workpiece conveying devices (forwarding or retracting along one direction), and two single-shaped workpieces are transferred. It becomes possible to convey by any of the workpiece conveyance apparatuses of a workpiece conveyance apparatus. As a result, any end of the front end and the rear end of the single-shaped workpiece can be transferred to the punched position in a free state, so that the end of either the front end or the rear end of the single-shaped workpiece is free. It is possible to perforate well.

In addition, since the front end and the rear end of the single-shaped workpiece can be transferred to the punching position by a series of operations of the two sets of work conveying apparatuses, it is not necessary to divide the punching work twice.

In addition, since the workpiece in the form of a single sheet can be held by the upper roller and the lower roller, the operation of clamping the single-shaped workpiece in the clamper is unnecessary.

For this reason, the drilling apparatus of this invention becomes a drilling apparatus which can carry out a drilling operation with the high productivity over the whole surface of the to-be-processed workpiece, and the objective of this invention is achieved.

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

(4) In the punching apparatus as described in said (3), it is preferable that the said drilling mechanism is further movable horizontally along one direction.

According to the punching device described in (3) above, the positional adjustment of the punching position in one direction in the single-shaped workpiece is to be performed by using two sets of workpiece conveying apparatuses having an upper roller and a lower roller. For this reason, high-precision position adjustment in the single-shaped workpiece is attained sufficiently.

However, with the recent fine pitch, it is also conceivable that a position adjustment at a higher position accuracy is required even in a single-shaped workpiece.

Even in such a case, not only the position adjustment of the punching position in one direction in a single-shaped workpiece can be performed as a punching mechanism like the punching apparatus described in (4) above, but also horizontally movable along the other direction. If the drilling mechanism can be performed by using a drilling mechanism that can move horizontally along the direction, the drilling mechanism can be moved with high precision by using a screw screw or the like. It becomes possible. For this reason, it becomes possible to perforate the workpiece of single shape with higher positional accuracy.

(5) In the punching device in any one of said (1)-(4), it is preferable that the workpiece | work guide surface for smoothly moving the workpiece of single-piece shape is provided in the circumference | surroundings of the said drilling mechanism.

In the case where the workpiece having a single-shape shape is rigid, the workpiece guide surface is not necessarily required. However, when the single-shaped workpiece is flexible, when transferring the single-shaped workpiece by one of the two sets of workpiece transfer apparatuses, the other direction in the single-shaped workpiece Due to the suspension of both ends and one end in one direction due to gravity, warpage and undulation may occur in the single-shaped workpiece. Even in such a case, by providing the workpiece guide surface as in the punching device described in the above (5), it is possible to effectively suppress the warpage and the occurrence of the single-shaped workpiece, and to smoothly transfer the single-shaped workpiece. It becomes possible.

In this case, it is preferable to set the height of the upper surface of the workpiece guide surface to a position slightly higher than the height of the upper surface of the die die (for example, about 0.050 mm to 2.0 mm).

(6) In the punching apparatus in any one of said (1)-(5), the space | interval of the said two sets of workpiece conveyance apparatuses is set shorter than the length along one direction in the single-shaped workpiece. desirable.

By configuring in this way, the workpiece of single-shape shape is always conveyed by the at least one workpiece transfer apparatus of two sets of workpiece transfer apparatuses, and reliable workpiece transfer is implement | achieved.

In this case, as the space | interval of two sets of workpiece conveyance apparatuses, although it is related also to the magnitude | size of a single-piece workpiece, and the magnitude | size of a drilling mechanism, it is preferable to set it as about 50 mm-150 mm.

(7) In the punching device in any one of said (1)-(6), the workpiece | work tip part detection arrange | positioned between the 1st workpiece conveyance apparatus of the workpiece | work standby position side, and the said drilling mechanism among the said two sets of workpiece conveyance apparatuses It is preferable to further provide an apparatus.

By such a configuration, the punching device can accurately know the position in one direction of the single-shaped workpiece, before the punching, and the subsequent precise drilling is possible.

As the work end detection device, in the initial state, the single-shaped workpiece is prevented from being advanced, and when the front-end of the single-shaped workpiece is detected, the detection signal is output and the single-shaped workpiece can be moved forward. The configured stopper can be preferably used.

(8) In the drilling device described in any one of the above (1) to (7), the workpiece of the single-shaped workpiece is moved from the workpiece standby position to the first workpiece transfer apparatus on the side of the workpiece standby position among the two workpiece transfer apparatuses. It is preferable to further provide the workpiece conveyance apparatus to convey toward.

By configuring in this way, only a single-shaped workpiece is supplied to a workpiece | work standby position, a single-shaped workpiece can be automatically conveyed to a 1st workpiece conveyance apparatus, and productivity of a drilling operation | work improves.

In this case, the workpiece in the form of a single piece to the work standby position can be supplied by a human hand or by a suction pad or the like described later.

(9) In the punching device in any one of said (1)-(8), the adsorption pad which conveys the workpiece of the single step shape before a punching process from a workpiece loading position toward a workpiece | work standby position, and the single-sheet shape after a punching process It is preferable to further provide the suction pad which conveys the to-be-processed object from a workpiece | work standby position toward a workpiece | work carrying out position.

By configuring in this way, it becomes possible to supply a single-shaped workpiece only by supplying the single-shaped workpiece before drilling process to a workpiece | work carrying in position. In addition, it is possible to recover the single-shaped workpiece only by recovering the single-shaped workpiece after the punching process from the workpiece carry-out position. This improves the productivity of the overall drilling operation.

(10) In the drilling apparatus in any one of said (1)-(9), it is preferable that the said drilling mechanism is a drilling mechanism which has a drilling die which consists of a punch die and a die die.

In the drilling apparatus of the present invention, it is of course possible to use a drilling mechanism using, for example, a laser or a drill as the drilling mechanism. However, it is preferable to use a drilling mechanism having a drilling die having a punch die and a die die as the drilling mechanism. desirable. By configuring in this way, the time required for drilling can be significantly shortened, and the productivity of the drilling work is improved.

(11) In the punching apparatus as described in said (10), it is preferable that the said drilling mechanism performs drilling in the state in which the guide pin does not exist between the said punching die and the said die die.

By configuring in this way, it becomes possible to load the large area single-piece workpiece between the punching die and die die, and it is possible to perforate the large area single-shaped workpiece.

(12) In the punching apparatus as described in said (10) or (11), it is preferable that the said metal mold | die for punches further comprises a stripper plate.

By configuring in this way, it is possible to prevent the single-shaped workpiece from sticking to the punch of the punching die after the punching operation, thereby improving the productivity of the punching operation.

(13) In the punching device described in (10) or (11), the punching mechanism is punched in a state where the gap between the punching die and the die is larger than the thickness of the workpiece in the form of a single piece. It is also preferred to practice.

By configuring in this way, 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.

In addition, since the punching is performed in a single-shaped workpiece in a non-pressing state, damage to the single-shaped workpiece can be suppressed and the reliability in quality can be improved.

In addition, since punching is performed in a state in which the gap between the punching die and the die die is larger than the thickness of the single workpiece, the punching die itself does not need to be raised at the time of drilling, and only the punch is lifted. Therefore, it becomes easy to speed up the perforation.

In this case, it is preferable to perform a puncture in the state where the space | gap between the said metal mold | die for punches and the said metal die | dye is 0.10 mm-5.0 mm.

Here, the space | gap made 0.10 mm or more is because when a space | gap is made less than 0.10 mm, it becomes impossible to perforate a comparatively thick workpiece. From this point of view, it is more preferable that the gap is 0.20 mm or more, and more preferably 0.30 mm or more. In addition, the space | gap was made into 5.0 mm or less because when the space | gap exceeds 5.0 mm, it will not become easy to ensure the positional precision of the front-end | tip part of a punch, and a die hole. This is because it is not easy to maintain the vacuum degree of the punch at the time of drilling. From this point of view, it is more preferable that the void is 3.0 mm or less, and even more preferably 2.0 mm or less.

(14) In the punching device according to any one of the above (10) to (13), the punching die or the die die is provided with a photographing through hole which is opened on the side of the workpiece in the form of a single piece. It is preferable that the imaging element is arrange | positioned in it.

With this configuration, the punching position can be read in the plane of the punch die and the die die by the imaging element. For this reason, the horizontal movement time from the reading of the punching position by the imaging element to the punching position of the punching die can be shortened, and the productivity of the overall punching work can be improved.

In this case, when the imaging by the imaging element is performed through the die hole in the die die, the drilling can be performed as it is at the reading position of the drilling position by the imaging element, so that the productivity of the drilling operation can be further increased. . In this case, since the reading of the punching position can be performed from the direction perpendicular to the single-shaped workpiece, there is an effect that the reading accuracy can be improved.

(15) In the punching device as described in (14) above, the metal mold | die in which the said imaging element is not arrange | positioned among the said metal mold | die for punches and the said die metal mold | die is provided with the illumination accommodating hole opened to the side of a to-be-processed workpiece, It is preferable that the light emitting element is arrange | positioned in this accommodation hole.

By configuring in this way, the illumination light from a light emitting element is used effectively for illumination of the to-be-processed workpiece. And the light which permeate | transmitted the workpiece | work of single-piece shape is read by an imaging element, and reading of a puncturing position is performed effectively.

(16) In the drilling device described in any one of (10) to (15), the drilling die further includes at least two positioning pins for positioning the punch die and the die die. It is preferable that each of the punch die and the die for electric die have at least two positioning pin holes arranged to insert the at least two positioning pins.

With this configuration, the punching die is attached to the punching device in a state where the punching die and the die die are accurately positioned using the positioning pins, and then the positioning pins are placed in the positioning pin holes of the punching die or By removing the die from the positioning pin hole of the die, the punching die can be attached to the punching device accurately and easily in a state where the precise positional relationship between the punching die and the die is maintained.

(17) In the drilling device described in (16), the drilling die includes the positioning pin in the positioning pin hole of the punch die and / or in the positioning pin hole of the die die. It is desirable to further have a positioning pin operator for moving.

With this configuration, it is possible to quickly remove the punching die from the punching device or to attach a new punching die to the punching device.

(18) In the perforation apparatus as described in said (3) or (4), the feeding mechanism for extracting the roll-shaped workpiece | work as a workpiece into a sheet form, and the winding-up mechanism for winding up the sheet-shaped workpiece to roll form It is preferable to further provide.

By such a configuration, it is possible to perforate not only the single-shaped workpiece but also the roll-shaped workpiece, thereby providing a highly versatile drilling apparatus.
