The individual punching units 21, 22, 23, 24, 25, 26 are fixed to the base 1 and arranged in parallel in the X-axis direction. The number of punching units 21, 22, 23, 24, 25, 26 is arbitrary as long as it is plural. This punching part 2 is used to punch the punches 21a, 22a, 23a, 24a, 25a and 26a into dies 21b and 22 by an appropriate driving mechanism.
It is designed to move up and down with respect to b, 23b, 24b, 25b, 26b.

The punching material supply unit 3 holds and supplies the ceramic green sheet 9 which is a punching material, and includes a main body box 31 and a pair of winding motors 3 housed inside the main body box 31.
2, 33, roll shafts 34, 35 connected to the winding motor and protruding outside the main body box 31, and the main body box 31.
And a pair of vacuum ports 36, 37 supported between the roll shafts 34, 35. The punching material supply unit 3 is movably supported by an X-axis moving mechanism 41 described later.

The moving mechanism unit 4 moves the ceramic green sheet 9 as a punching material in the X-axis and Y-axis directions via the punching material supply unit 3, and includes an X-axis moving mechanism 41 and a Y-axis moving mechanism 42. The X-axis moving mechanism 41 moves the punching material supply unit 3 in the X-axis direction, and the main body box 41a arranged in the X-axis direction.
And a screw rod 41b disposed inside the main body box 41a,
It is composed of an X-axis motor 41c which is connected to the screw rod 41b and rotates the screw rod 41b, and a clamp 41d which is screwed to the screw book 41b and supports the main body box 31 of the punching material supply unit 3. The X-axis moving mechanism 41 is movably supported by a Y-axis moving mechanism 42 described later. The Y-axis moving mechanism 42 moves the X-axis moving mechanism 41 in the Y-axis direction.
a clamp 42a supporting a, a screw rod 42b screwed to the clamp 42a and arranged in the Y-axis direction, and a Y-axis motor 42c fixed to the base 1 and connected to the screw rod 42b for rotating the Y-axis motor. ,
It is composed of two guides 42d, 42e which are fixed to the base 1 and are engaged with and guided by the main body box 41a of the X-axis moving mechanism 41.

The control unit B includes a main body 5 having a built-in computer and a main body 5
And an operation board 7 connected to the main body 5 and an offset microscope 8 connected to the main body 5 and installed near the perforated portion 2.

In such an embodiment, the ceramic on tape 91
The ceramic green sheet 9 in a state in which 92 is applied to a uniform thickness and dried is wound around the roll shafts 34, 35 of the perforated material supply unit 3 to form a roll.
A certain width is stretched between 35. This ceramic green sheet 9 is stretched by tape 9 in addition to about 0.1 mm of ceramic 92.
2 has a thickness of about 0.3 mm and is in a state like a flat plate, but by operating the pair of vacuum ports 36, 37 of the perforated material supply unit 3, tension is applied to the ceramic green sheet 9 and It can maintain a flat plate-like state.

The ceramic green sheet 9 stretched in this way is
A punching unit that is moved to the punching section 2 by the moving mechanism section 4 and is effectively held and supplied, and the punching position is set and the operation is selected using the offset microscope 8 of the control section B.
The settings of 21,22,23,24,25,26 are input to the control unit B, and various shapes of drilling work are performed based on this input.

By driving the take-up motors 32 and 33 of the punching material supply unit 3, it is possible to supply the unmachined portion within the stretched width of the ceramic green sheet 9.

As described above, in addition to the illustrated embodiment, the moving mechanism portion 4 may be an embodiment having a structure using another actuator such as a cylinder.

Further, the control unit B is not always necessary, and may be an embodiment having a structure for manual control or an automatic / manual switching structure.

[Effects of the Invention] As described above, in the punching device for a ceramic green sheet according to the present invention, the ceramic green sheet in a state where the tape is not peeled is effectively held and fed to the punching portion
There is an effect that it is possible to perforate a ceramic green sheet in a state where the tape is not peeled off.

In addition, since the ceramic green sheet in which the tape is not peeled off is effectively held and supplied to the perforated part, it is possible to handle it without reducing the workability of punching work or making it difficult to punch various shapes. There is an effect that can be.
