Description

The present invention relates to a punching device for a ceramic green sheet.

More specifically, the present invention relates to an improvement of a device for punching various shapes on a ceramic green sheet which is a ceramic sheet before firing which is used as a material for a circuit board.

[Prior Art] Conventionally, as means for punching a ceramic green sheet,
For example, apply ceramic to a uniform thickness on a tape (polyester resin, etc.), dry it, peel the ceramic part from the tape to obtain a ceramic green sheet, and punch it using a predetermined punching device. Is being carried out.

[Problems to be Solved by the Invention] In the above-mentioned conventional ceramic green sheet punching means, since the ceramic green sheet obtained by peeling the ceramic portion from the tape is extremely thin (about 0.1 mm), There are problems that the handling becomes troublesome, the workability of the drilling work is deteriorated, and it becomes difficult to drill various shapes.

The present invention has been made to solve such a problem, and an object thereof is to provide a punching device capable of punching a ceramic green sheet in a state where a tape is not peeled off.

[Means for Solving the Problems] In order to achieve the above-mentioned object, a punching device for a ceramic green sheet according to the present invention includes a plurality of punching units each having a punch and a die having different shapes and sizes, in the X-axis direction. And the ceramic green sheet in which the ceramic is applied to the tape to a uniform thickness and dried, and the ceramic green sheet is stretched with a certain width between the rolls arranged in the X-axis direction. A means including a drilling material supply section to be installed and a moving mechanism section for moving the drilling section in the X-axis direction and the Y-axis direction is adopted.

[Operation] According to the above-mentioned means, the ceramic green sheet in a state where the tape is not peeled off is further wound and wound in a roll shape of the perforated material supply section, and a plurality of moving mechanism sections are provided for the ceramic green sheet. Since the perforated portion having the punching unit is moved, the ceramic green sheet is effectively held and supplied to the perforated portion, so that the punching work can be performed on the ceramic green sheet in a state where the tape is not peeled off. The purpose of doing is achieved.

The punching units 21, 22, 23, 24, 25, 26 are individually supported by a moving mechanism section 4 which will be described later and arranged in parallel in the X-axis direction. In addition, this punching unit is 21,22,23,24,25,2
The number of 6 is arbitrary as long as it is plural. This perforated part 2
Is a punch 21a, 22a, 23a, 24a, 25a, by a suitable drive mechanism.
The 26a can be moved up and down with respect to the dice 21b, 22b, 23b, 24b, 25b and 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 fixed to the base 1.

The moving mechanism unit 4 moves the punching unit 2 in the X-axis and Y-axis directions, and includes an X-axis moving mechanism 41 and a Y-axis moving mechanism 42. The X-axis moving mechanism 41 moves the punching part 2 in the X-axis direction.
Body box 41 arranged in the axial direction and having the perforated portion 2 fixed thereto
a and a screw rod 41b arranged inside the main body box 41a
And an X-axis motor 41c that is connected to the screw rod 41b and rotates it.
And a clamp 41d fixed to the main body box 41a by being screwed into the screw rod 41b. This X-axis moving mechanism 41
It is movably supported by a Y-axis moving mechanism 42 described later. Y
The axis moving mechanism 42 moves the X axis moving mechanism 41 in the Y axis direction, and is arranged in the Y axis direction by being screwed to the clamp 42a that supports the body box 41a of the X axis moving mechanism 41. Screw rod 42b, Y-axis motor 42c fixed to the base 1 and connected to the screw rod 42b to rotate the rod 42b, and the base 1
And two guides 42d and 42e fixed to 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
A display 6 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 material supply unit 3.

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.
