After the green sheet 101 is oriented at a predetermined position and in a predetermined direction by bringing the edges into contact with each other, the green sheet 101 is fixed to the upper surface of the jig 102 by vacuum suction.

After that, the slider 105 is moved along the guide bar 107, the peeling roller 104 is moved from outside the area where the green sheet 101 is placed on the jig 102 to the position of one end of the green sheet 101, and the arm 109 is rotated. to move it from the cent position to the release position.

After that, one end of the film is peeled off from the green sheet 101 by hand at one end in the sliding direction of the sliders 105 and 106, and the one end is inserted between the beam 103 and the peeling roller 104, and separated by n1. The roller 104 is returned to the set position and one end of the film is sandwiched between the beam 103 and the peeling roller 104.

Furthermore, after this, the film is peeled off from the green sheet 101 by manually pulling up one end of the film that protrudes upward from between the beam 103 and the peeling roller 104.

When one end of the film protruding from between the beam 103 and the peeling roller 104 is pulled up by hand, the peeling roller 10
The peeling roller 104 moves to the left in FIG. 5 while rotating in conjunction with the film being pulled up.
As the arm 109 and sliders 105 and 10 move,
6 and beam 103 move in the same direction.

04 is biased to the set position by the switching bias spring 110, when the film is strongly pulled, the peeling roller 1
04 may swing from the set position to the release position against the switching biasing spring 110, and the green sheet 10
1 follows the film and rises from the top surface of the jig 102, and an uncured green sheet 110 is formed between the part where the film is peeled off and the part held by the beam 103.
1 may be stretched and deformed.

Moreover, since the film is pulled up by hand, the force acting on the green sheet 101 through the film is not constant, and the elongation of the green sheet 101 partially changes.
Moreover, variations occur in the deformed state for each green sheet 10l.

Therefore, when the green sheets 101 from which the films have been peeled are stacked in the subsequent lamination process, each green sheet 1

Guide bars 7 and 8 are provided on both sides in the axial direction of the roller and slide and guide the sliders 5 and 6 in a direction perpendicular to the axial center of the peeling roller.

The jig 2 is configured to fix a green sheet placed on its upper surface by vacuum suction.

The reference portion 11 is made of a tape attached to the top surface of the jig 2 in accordance with the outer shape of the green sheet.

The pair of sliders 5 and 6 are fixed to each other via a connecting frame l4, and the peeling roller 4 is rotatably supported by a pair of bearings 15 and 16 fixed to the connecting frame 14, so that both sliders 5 and 6 are fixed to each other via a connecting frame l4. The shaft center position is fixed and rotatably supported. Note that a peeling roller 4 is provided on the upper surface of the connecting frame 14.
A film receiving plate 17 extending in the forward direction is fixed, and the film peeled from the green sheet 1 by the peeling roller 4 is placed on the upper surface of this film receiving plate 17.

A presser roller 3 that contacts and separates from the peeling roller 4 is swingably supported on both sliders 5 and 6 via an arm 9. The biasing spring 1 is switched to the release position away from the
The power is switched to 0 and energized.

Both sliders 5 are located on one side of the peeling roller axis of the jig 2.
- A constant speed drive device 12 is provided to drive the motor 6 at a predetermined speed.

This constant speed drive device 12 may be configured to drive both sliders 5 and 6 at a predetermined speed, and includes, for example, a motor 12a that rotates at a constant speed, a drive screw shaft 12b connected to the motor 12a, and a drive screw shaft 12b connected to the motor 12a. The slider 12C is screwed onto the drive screw shaft 12b so as to be able to move forward and backward, and is fixed to one of the sliders 5 and 6.

Note that this constant speed drive device 12 includes a microswitch 12d that detects that the slider 5 has reached the end point in the forward direction, and a microswitch 12e that detects that the slider 5 has reached the end point in the backward direction. It is equipped with

Further, a rasock 13a is provided over a predetermined stroke range parallel to the guide bar 7 that guides the slider 5, and the pinion 13b fixed to the tip of the shaft 4a of the peeling roller 4 is engaged with this rastock. This constitutes a synchronizing device 13 that synchronizes the circumferential speed of the peeling roller 4 with the advancing speed of the sliders 5 and 6.

Further, the circumferential surface of the peeling roller 4 and the circumferential surface of the presser roller 3 are covered with rubber.

The procedure for peeling a film using this film peeling device is as follows.

First, the constant speed drive device l2 is operated in the reverse direction to move the peeling roller 4 out of the area of the jig 2 where the green sheet 1 is placed, and then the green sheet 1 with the film attached is placed on the top surface of the jig l. Then, after bringing the edge of the green sheet 1 into contact with the reference part 11 and orienting the green sheet 1 at a predetermined position and in a predetermined direction, the green sheet 1 is fixed to the top surface of the jig 2 by vacuum suction. .

Thereafter, the constant speed drive device 12 is operated in forward motion to move the peeling roller 4 along the guide bar 7.8 from outside the area where the green sheet 1 is placed on the jig 2 to the position of one end of the green sheet 1. The presser roller 3 is moved from a cent position where it contacts the peeling roller 4 to a release position away from the peeling roller 4.

After that, one end of the film is manually peeled off from the green sheet 1 at one end in the sliding direction of the sliders 5 and 6, and the one end is inserted between the presser roller 3 and the peeling roller 4, and the film is pressed. - Return the presser roller 3 to the center position and
One end of the film is sandwiched between the roller and the peeling roller 4.

Furthermore, after this, the constant speed drive device 112 is operated in forward motion to move the sliders 5 and 6, the peeling roller 4, and the press roller 3 from one end of the green sheet 1 to the other end.

After sandwiching one end of the film between the presser roller 3 and the peeling roller 4, the constant speed drive device 12 is operated in forward motion to remove the sliders 5 and 6, the peeling roller 4, and the presser roller 3 from one end of the green sheet 1. When the peeling roller 4 is moved in the direction of the other end, the peeling roller 4 is rotated by the synchronizer 13 so that the circumferential speed of the peeling roller 4 is synchronized with the advancing speed of the sliders 5 and 6. The film supported between the peeling roller 4 and the slider 5
- It is peeled off from the surface of green sheet 1 at the same speed as that of green sheet 6.

Here, the film is peeled off from the green sheet 1 by frictional force with the circumferential surface of the peeling roller 4 driven by the constant speed drive device 12.
- Since the green sheet 1 is rotatably supported with the axis position fixed on the green sheet 6, there is no fear that the peeling roller 4 will move upward due to the peeling force, and the green sheet 1 can be sufficiently strongly attracted to the jig 2. I can do it. The vacuum suction force of the jig 2 prevents the green sheet 1 from floating up from the upper surface of the jig 2 while being attached to the film, and the deformation of the green sheet 1 is significantly reduced.

Further, since the constant speed drive device 12 is configured to drive the sliders 5 and 6 at a predetermined speed, the distribution of the force acting on each green sheet 1 from the peeling roller 4 is constant, and each green sheet l The distribution of deformation that occurs in the area becomes constant.

〔Effect of the invention〕

As explained above, according to the present invention, the film is peeled off from the green sheet by the rotational force of the peeling roller driven by a constant speed drive device, and the peeling roller is supported by both sliders with the axial center position fixed. Therefore, there is no fear that the peeling roller will move upward due to the force of peeling off the film, and the green sheet can be sufficiently attracted to the jig. This prevents the green sheet from floating up from the jig due to the film, and deformation of the green sheet is suppressed to a small level.

In addition, since the constant speed drive device is configured to drive the slider at a predetermined speed, the distribution of the force acting on each green sheet from the peeling roller is constant, and the distribution of deformation occurring on each green sheet is constant. become.

And, as these effects work synergistically,
When a large number of green sheets from which films have been peeled are laminated in a later lamination process, the position of the via conductor of each green sheet is prevented from shifting, and it is possible to prevent conductor connection defects due to positional shift of the via conductor.
