Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible work punching device.

[0002]

2. Description of the Related Art Conventionally, there have been various kinds of green tapes, TAB tapes, flexible printed wiring board tapes and sheet-shaped ones thereof, which are laminated with ceramic green sheets, as objects to be punched by a punching device having flexibility. To do. The hole shape to be drilled in the flexible work is not only a round hole, but also a non-circular hole such as a rectangular hole or a U-shaped hole. The non-circular holes are not only parallel to the long and short sides of the tape (work having flexibility) or the sheet (work having flexibility),
In many cases, punching is performed at a position displaced in the θ direction. For example, in a flexible printed wiring board, etc., a plurality of products are inclined in the θ direction with respect to the long side and the short side of the tape or sheet and have a predetermined arrangement pattern. In the case of a tape, in the case of a tape, punching provided with a punch and a die corresponding thereto is provided between a feeding device for feeding in the X-axis direction from a roll material and a winding device for winding the same. A punching section consisting of a unit and a camera is provided so as to be controllably movable in the X and Y axis directions, and the punching section is set to X each time the tape is intermittently fed.
・ The camera is controlled to move in the Y-axis direction, the reference point is centered by the camera, and the outer periphery of the end of the product existing at a predetermined position separated from the reference point by a predetermined distance is punched or the end of the end is detected by the pattern matching method. It is punched by matching the outer circumference. Also, in the case of a sheet, it can be removably attached or locked to a jig called a work holder, and the work holder can be controlled and moved in the X and Y axis directions, and the camera is used to center the reference point. Then, the outer periphery of the end portion of the product existing at a predetermined position separated from the reference point by a predetermined distance is punched or the outer circumference of the end portion is matched by the pattern matching method.

By the way, such a tape is intermittently fed between the feeding device and the winding device by a predetermined amount toward the work area of the punching portion, and the sheet is similarly moved in the X and Y axis directions. The tape is fed, but in the case of tape, since it is a feeding method that extends across the feeding roller and the take-up roller, a slight θ direction is present at the product end position with respect to the X-axis direction, which is the feeding direction. There is also a case where even in the case of a sheet, the sheet to be perforated is slightly displaced in the θ direction due to a strain or the like generated in the sheet due to the balance with the adhesive tape.

When such a phenomenon occurs, the punch cannot be arranged along the outer circumference of the end of the product only by controlling the punching portion itself in the X and Y axis directions, resulting in a punching error, which leads to a disconnection with the connector. Make the connection bad. Also, when holding the sheet in the work holder, adhesive tape is adhered to the upper surface of the work holder, and the sheet is held by the adhesive tape. The sheet is affixed to the four sides of the sheet or the two sides of the opposing structural frame section across the sheet. Therefore, since both the sheet and the work holder have a small attachment area, it is necessary to attach the adhesive tape with a relatively large strength in order to hold the sheet. The peeling work is very troublesome, and when peeling, there is a problem that the work holder is sometimes rubbed, the work holder is damaged, and the sheet adhering surface is damaged, which requires a special peeling machine.
