DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a perforation system for perforating a soft work such as a green sheet for forming a laminated substrate having a different perforation pattern such as a ceramic package for a semiconductor or a flexible substrate film for each perforation pattern. Things.

2. Description of the Related Art A conventional drilling system of this type is disclosed in Japanese Patent Application Laid-Open No. 9-66497. This is transferred by a conveyor device and a transfer device to each of a plurality of punching devices necessary to obtain a punching pattern determined by a unique code attached to a work holder, and while a certain punching device is punching, another Drilling different hole shapes with different drilling devices, and performing the role of multiple drilling devices according to the determined drilling pattern, and managing the number and type of drilling patterns. Then, when being carried into the most upstream conveyor device so as to eliminate some of the perforation patterns, a subsequent perforation pattern is determined and the perforation is passed between the perforation devices. It is excellent in productivity that an average number of laminated substrates perforated for each perforation pattern can be obtained.

[0003]

By the way, in the above-mentioned drilling system, a soft work wound in a roll shape is cut into a predetermined length and a unique code is attached thereto as a preparation before performing the drilling process. It is attached to the work holder. The method of attachment is to attach the cut work to the work holder using an adhesive tape, or to attach a reference hole to the work after cutting. It is common practice to detect the drilling position by processing, and this reference hole may be used as the reference coordinate at the time of drilling. And a method of attaching them together.

However, in any case, a cutting operation for cutting the work in advance and an attaching operation for attaching the cut work to the work holder (including the drilling operation in the latter case) are performed. However, it involves inefficient processes as a whole. Moreover, it is not economical because it is necessary to prepare a plurality of work holders for mounting the work in advance, and since the work holder has a unique code, the work may come off or come off from the work holder. If not, there is a risk that management may become impossible, and there is room for improvement as a system.

Further, among the most upstream drilling apparatuses of this kind of drilling system, there is a type in which a plurality of work holders on which workpieces are mounted are previously stored in a multi-stage shape and a magazine provided with an elevating mechanism so as to be gradually clamped. However, this is likely to be mechanically complicated and expensive. In addition, since the above-mentioned pre-setup work is performed outside the apparatus, it cannot be denied that it is inefficient. Therefore, the present invention
A flexible workpiece such as a green sheet or a film for a flexible substrate wound in a roll is set as it is without performing external setup work, and a workpiece having various perforation patterns for fine and high density is obtained. It is possible,
In addition, when the work is on a substrate for lamination, a work with an average number of works having different perforation patterns in each layer can be obtained, and a perforation system excellent in productivity and economy which does not have a risk of making work management impossible. It is intended to provide.

[0006]

The technical means taken to achieve the above object is a work for feeding and cutting a soft work such as a green sheet or a film for a flexible substrate wound into a roll by a required length. The product is provided with a feeding unit, a table on which a cut workpiece that is fed by a required length by the workpiece feeding unit is mounted, and on which a perforated workpiece is mounted, a punch, and a die that receives the punch. While moving the work by sucking and holding the perforated portion for perforating the cord, the engagement hole and the required hole, and the peripheral portion of the upper surface of the work cut to a required length by the work feeding means and placed on the upper surface of the table. A first punching device including moving means for releasing a workpiece drilled at the punching portion and releasing the workpiece drilled thereon, and placing the workpiece on the table; The work is moved by a moving means holding the work by engaging the engagement pin with an engagement hole drilled by the first punching device and having the work holder provided with the engagement pin projecting therefrom. A second punching device group including a plurality of types of punching devices for punching at a punching portion such as a punch and a press die,
A reciprocating conveyor device that is provided in each of the first punching device and the second punching device group and transfers a workpiece to an adjacent punching device, and a punched work that is provided in the first punching device and is provided in the first punching device. A first transfer device that transfers a work between a table to be placed and a conveyor device provided in the first punching device, and a work holder that is provided in each of the punching devices of the second punching device group and holds the work. And a second transfer device for transferring a work between the conveyor device and a conveyor device, and the order of a punching device required by the work is determined each time the work, which has been cut out by a required length by the work feeding means, is carried in, A work is transferred between the conveyor device, the first and second transfer devices, and the respective punching devices, and a series of punching processes are integrally controlled, and the product code and the punching pattern are associated with each other. Characterized in that it comprises a control unit for recording Te.

[0007] Here, the product code is a marker for recognizing what is being processed on the work after the processing is completed and for managing the work. By reading with an image analyzer using a CCD camera or a reader similar to a barcode reader, the work can be recognized. For example, if the work is a green sheet for a laminated board, it can recognize and determine which product is in which layer of which product, and print the wiring in the subsequent process based on the product code A printing step, a laminating step, or a cutting step is performed. This product code itself is a plurality of holes corresponding to numbers and symbols, and the numbers and symbols do not necessarily have to have regularity like continuous numbers (different drilling patterns are the same product). It is necessary not to be a code), and the punching data corresponding to the number or symbol is recorded in the control unit, and the contents can be recorded on a recording medium such as a magnetic disk so that the work can be managed. .

According to the above technical means, the work feeding means of the first punching device sends the work to the upper surface of the table adjacent to the work feeding means, cuts the work when the required length is reached, and places the work on the upper surface of the table. Then, based on a command from the control unit, the moving means of the drilling device moves in the X and Y directions to move above the work placed on the table upper surface, and suction-holds the peripheral portion of the upper surface of the work. Then, the moving means holding the work by suction is controlled to move to the perforation portion of the perforation device to operate the second perforation device (which is the earliest available, etc.), the number of processed workpieces, and the number of processed workpieces. In consideration of the number of sheets (when there are a plurality of desired drilling patterns, the number of finished and processed sheets of each of several kinds of drilling patterns), the order of the punching device required for the work is determined and the punching is performed. Only when there are a plurality of patterns, the drilling pattern to be processed is determined. At the same time, the product code of the work to be drilled and the drilling pattern (there may be only one type of drilling pattern) are recorded in association with each other.

The product code and the drilling pattern are associated with each other. In particular, when there are several types of drilling patterns, the product code is set to a serial number, and the drilling pattern determined later according to the operating condition of each drilling device. To make it correspond to a pattern,
The product code may be determined based on the determined perforation pattern, and the association is not particularly limited.

After that, the drilling is performed based on the required drilling data, the moving means is controlled to move to the placing section, the suction is released, and the workpiece is dropped and placed on the table. If there is no necessity, immediately after the product code and the engagement hole are pierced, the moving means is controlled and moved to the mounting portion, the suction is released, and the work is dropped and mounted on the table. The work placed on the table of the first punching device is provided to the first transfer device, the conveyor device provided in the device, and each second punching device according to the order of the punching devices determined by the control unit. The workpiece is transferred to the second punching device for performing the next punching process through the conveyor device and the second transfer device, and the workpiece is held by engaging the engaging pin with the engaging hole drilled by the first punching device. While moving the workpiece by the moving means, a punching section such as a punch or a press die punches a required punching pattern (only a portion where the punching device shares a role). In the same manner, the transfer is performed between a plurality of piercing devices assigned roles until the required piercing pattern is completed, the piercing is performed, the soft work wound in a roll is cut, and the desired work is pierced. Finalize.

Place and hold by suction. The table is moved to the unloading position side, and the work held by the first placement unit positioned between the work unloading unit and the unloading position is released by suction and is held by the moving unit that is on standby ( At this time, the second mounting portion is located at the unloading position.) The moving means holding the workpiece by suction in this manner is controlled to move to the perforated portion so that the product code and the engaging hole are provided. When it is necessary to pierce the workpiece with the piercing tool of the piercing portion of the piercing device, the piercing process is performed based on required piercing data after piercing the product code and the engaging hole.

In the meantime, the table is moved to the work feeding means side, and the work is sent out from the work feeding means to the first mounting portion for a required length, cut, mounted on the first mounting portion and sucked and held. deep. When the processing is completed, the moving means is controlled to move to the second mounting portion located at an intermediate portion between the work feeding means and the unloading position, to stop the suction of the air, return to the positive pressure, release the suction, and drop the suction. The work is placed on the second placing portion and held by suction. Then, the table is moved to the unloading position side to release the suction of the perforated work placed on the second placing portion,
At the same time as the first transfer device unloads the workpiece to the conveyor device provided in the first punching device, the moving means in the standby state, which is located at an intermediate portion between the workpiece feeding means and the unloading position, is moved to the first position located at the same position. The released work is sucked and held by the mounting section and sucked and held. In this way, the first punching device cuts the soft work wound in a roll shape and simultaneously carries in and out the work (claim 2).
