The product input shelf 502 connected to the ball screw 503 advances along the product input LM guide 501 to supply the back plate. When the attachment of the double-sided tape is completed, the product loading servomechaner 504 rotates in a direction opposite to the feeding direction, and the product loading shelf 502 is moved backward to eject the back plate with the double-sided tape attached thereto.

The product support table 505 can be fixed at another position of the product insertion shelf 502 and the product support table 505 can be mounted on the upper part of the product insertion shelf 502 to provide a replaceable jig 507, It can also be used in the form of. Therefore, it is possible to support products having various sizes and shapes by moving the product support base 505 or by replacing the jig 507.

In addition, projections, that is, adhesive guides 506, are formed on the upper side of the product input shelf 502 or the upper side of the jig 507, Therefore, when the double-sided tape is squeezed, there is no lifting phenomenon of the other side by the squeeze roller 402 (Fig. 6) on one side.

3 to 4, the feeding unit 2 of the apparatus for peeling and attaching a tape using numerical control according to the present invention comprises a double-sided tape roll 201 on which a double-sided tape in a roll form is mounted on one side, A roll server motor 202 connected to the tape roll 201, a tension part 21 located on the other side of the roll server 201, and a height fixing roller 203 located on the lower side surface of the tension part 21.

As described above, the double-sided tape 201 can be unwound or wound on the double-sided tape roll 201 in accordance with the rotation of the roll servo motor 202 and supplied to the tension unit 21. The double-sided tape having passed through the tension portion 21 can be fed to the next stage at a fixed height through the height fixing roller 203.

The tension unit 21 includes a plurality of tension rollers 210, a roller socket 211 connected to the tension roller 210, and a roller socket 211 for fixing the moving direction of the socket through the roller socket 211 A plurality of weight weights 213 connected to the wires 216 and a plurality of weight wires 213 connected to the wire sockets 211 and connected to the weights pulley 214 connected to the weights pulley 214, And a plurality of tension sensors 215 for measuring the movement of the roller socket 211.

The double-sided tape supplied through the above-described configuration is loaded on one side tension roller 210 of the roller socket 211 and is twisted in half to avoid contact between the roller and the adhesive surface 900 up to the tension roller 210 located at the lower side And it goes down. The double-sided tape having passed through the lower tension roller 210 is twisted to be wound on the other side of the roller socket 210 by a half turn so as to be put on the other tension roller 210.

The double-faced tape having passed through the tension roller 210 is twisted once again, and is fed horizontally through the height fixing roller 203 located on the other side of the lower portion.

More specifically, the double-sided tape is twisted in half in three portions of B shown in the figure (every time when the tape passes through the tension roller 210), and the tension roller 210 contacting the double- (Fig. 4A: contact with the roller is a release paper). Thus, regardless of whether the double-sided tape moves upward or downward, the adhesive surface 900 can be preserved because the roller and the adhesive surface 900 are not adhered to each other regardless of the directional change.

The roller socket 211 is connected to the weight 213 via a wire 216 extending over the weights pulley 214 located at the upper portion of the roller socket 211. This causes the roller socket 211 to be always pulled up And the double-sided tape that is stretched over the tension roller 210 of the roller socket 211 maintains tension.

Further, when pulled to attach the double-sided tape, the pulling force of the double-sided tape across the tension roller 210 becomes larger than the pulling force of the weight 213, the roller socket 211 is lowered, The tension is maintained while descending due to the spring 213.

When the roller socket 211 comes down to the position of the tension sensor 215 located below, the roll servo motor 202 rotates to release the double-sided tape roll 201 and supply the double-sided tape.

When the double-sided tape is supplied, the roller socket 211 moves up. When the tension sensor 215 reaches the position of the tension sensor 215, the roll servo motor 202 stops and the supply of the double-sided tape stops.

Thus, the double-sided tape can always maintain the same tension, and although the weight 213 is used as a preferred embodiment, it is possible to replace it with a spring or to delete or add some rollers.
In addition, the tension guide 212 has a length of at least 1/4 of the length of the double-sided tape to be attached, which is effective because it can provide the length of the double-sided tape to be attached by one supply in the double-sided tape roll 201, There are no special restrictions.
