Referring to FIG. 10, the structure of the embodiment of the additional board separating unit 110 of the present invention is provided. The additional board separating unit 110 is separately provided from the mechanism 100 for attaching the additional board to the flexible circuit board.

As described above, the embodiment of the additional board separating unit 110 of the present invention comprises an additional strip strip unwinder 111, an upper strip rewinder 112, and a lower strip rewinder 113.

As shown in Fig. 11, it is driven by a torsion motor 118 to drive the lower belt rewinder 113 to rotate at a predetermined torque.

Since the lower belt rewinding device 113 is rotated by a predetermined torque, the additional strip body 7 (shown in FIG. 6) sent by the additional strip strip unwinder 111 can be provided with a preset. pull.

A force roller 119 is provided on the side of the additional strip strip unwinder 111, whereby the pulling force provided by the lower strip rewinder 113 to the additional strip body 7 is maintained at a fixed value.

In other words, the tension roller 119 is used to simultaneously actuate the additional strip body 7 and the lower belt rewinder 113 at the same tensile force value to avoid the transfer of the pulling force to the additional strip strip unwinder 111.

To achieve the above objective, as shown in FIG. 12, the tension roller 119 includes a support roller 119a and a friction roller 119b, and the additional strip body 7 is horizontally disposed between the tension roller 119 and the support roller 119a. The support roller 119 is vertically pressed upward against the lower surface of the additional strip body 7, and the friction roller 119b is pressed vertically downward with respect to the support roller 119a to the additional strip body 7. Above the surface.

The support roller 119a is driven by a cylinder 119f to generate an upward pressing force, thereby applying a predetermined gripping force to the additional strip body 7.

The friction roller 119 is configured to receive a frictional force. The rotation shaft of the friction roller 119b is coupled to a bearing 119c. The surface of one of the axial ends of the bearing 119c is in contact with a pressing member 119e, and the axial direction of the pressing member 119e. The displacement is adjustable, and the axial displacement of the pressing member 119e is adjusted by an adjustment knob 119d.

Therefore, the rotational resistance of the friction roller 119b can be adjusted by the above-described frictional force adjusting mechanism to adjust the pulling force of the additional strip body 7, and the pulling force can be prevented from being transferred to the additional strip body unwinder 111.

As shown in FIG. 11, the additional strip body unwinder 111 is coupled to a perma torque 1110 for providing the additional strip unwinder 111 with a predetermined resistance moment.

The torque device 1110 can provide the pulling force of the additional strip body 7 disposed between the additional strip strip unwinder 111 and the tension roller 119 at a specific value.

As shown in FIG. 11, the upper belt rewinder 112 is driven to rotate by a drive motor 117 and a magnetic powder clutch 1111.

The drive motor 117 is a continuous electric motor, and the rotational driving force of the magnetic powder clutch 1111 is provided by the driving motor 117, and an adjustment driving force (that is, the received rotational driving force) is transmitted by the magnetic powder clutch 1111 to the upper belt body. The winder 112 can thus maintain the tension of the upper tape rewinder 112 at a predetermined value.

Since the weight and mass moment of inertia of the upper belt rewinder 112 increase with the thickness of the wound top strip 6 (see FIG. 6), the top layer strip 6 can be avoided by the magnetic powder clutch 1111. It is torn by its material factor.

In other words, the control element (not shown) for controlling the magnetic powder clutch 1111 rewinds the tension roller 119 and the upper layer according to the thickness of the top tape body 6 wound by the upper tape rewinder 112. The tension between the devices 112 is maintained at a predetermined value.

As shown in FIG. 11 , the thickness of the top strip 6 wound by the upper tape rewinder 112 is measured by a thickness measuring mechanism, and the thickness measuring mechanism includes a rotating shaft 1112 and a sensing. The rotating shaft 1112 is integrated into the upper belt rewinding device 112 and can be rotated together with the upper belt rewinding device 112. The sensor 1113 is disposed on the rotating shaft 1112 outside the upper belt rewinding unit 112. Rotate through the path.

The number of rotations of the upper tape rewinder 112 is measured by the rotating shaft 1112 and the sensor 1113, so that the thickness of the top tape body 6 wound by the upper tape rewinder 112 can be known.

Referring to FIG. 6, the tension of the additional strip body 7 is related to the following factors. The tension between the tension roller 119 and the lower belt rewinder 113 is greater than the additional strip unwinder 111 and the tension roller. The tensile force of 119 is also greater than the tension between the tension roller 119 and the upper belt rewinder 112.

If the tension between the additional strip unwinder 111 and the tension roller 119 is too large, the additional strip body 7 may be damaged by tears, scratches, and the like. Therefore, in a preferred case, the tension between the additional strip unwinder 111 and the tension roller 119 should be kept to a minimum.

In addition, if the tensile force between the tension roller 119 and the upper belt rewinder 112 is greater than the tension between the tension roller 119 and the lower belt rewinder 113, the additional strip body 7 passing through the tension roller 119 may be caused to be rolled.
