Hereinafter, with reference to FIGS. 1 to 3, the operation of the strip bonding apparatus according to an embodiment of the present invention will be described.

For bonding the leading strip S1 and the trailing strip S2, first, the tail portion of the leading strip S1 is stopped at the application position of the bonding solvent as shown in FIG.

That is, when the tail portion of the preceding strip S1 is positioned directly below the nozzle 100 , the movement of the preceding strip S1 is stopped.

And, when the movement of the preceding strip S1 is stopped, the nozzle 100 descends directly above the tail portion of the preceding strip S1 by the nozzle actuator 110, and at this time, the nozzle 100 precedes the bonding solvent. It is applied by spraying on the surface of the tail of the strip (S1).

In addition, the width direction moving unit moves the nozzle 100 along the width direction of the preceding strip (S1).

That is, as the drive motor 130 is driven, the connection belt 121 connected to the drive shaft 131 rotates the ball screw 120 , and when the ball screw 120 rotates, the ball screw is driven by the female nut 140 . The rotational motion of 120 is converted into a linear motion of the nozzle actuator 110 .

Accordingly, the nozzle 100 moves linearly along the ball screw 110 together with the nozzle actuator 110, and in the width direction (X direction in FIG. 1) of the preceding strip S1, The bonding solvent is applied over the entire width of the tail surface.

In this way, when the nozzle 100 applies the bonding solvent to the entire width direction of the surface of the tail of the preceding strip S1, the nozzle actuator 110 is returned to the original position by driving the driving motor 130, , to raise the nozzle 100 to its original position by the nozzle actuator 110 .

As such, when the bonding solvent is applied over the entire width of the surface of the tail of the preceding strip S1, the driving motor of the line adjusting device 300 is driven to rotate the rotation shaft by a set angle.

By the rotation of the rotating shaft, the leading end of the strip guide 310 (the end side close to the tail of the preceding strip) is lifted above the tail of the preceding strip S1.

As described above, in a state where the front end of the strip guide 310 is lifted above the tail portion of the preceding strip S1 , the head portion of the trailing strip S2 is moved to the upper portion of the tail portion of the preceding strip S1 .

When the head portion of the trailing strip S2 is positioned directly above the tail portion of the preceding strip S1, the movement of the trailing strip S2 is stopped, and the driving motor of the line adjustment device 300 is driven to set the rotation shaft to its original position. rotate to

When the axis of rotation is rotated to the original position, the leading end of the strip guide 310 is positioned on the same plane as the surface of the tail of the preceding strip S1, and the head of the trailing strip S2 is It is superimposed on the surface of the tail part.

As such, when the head portion of the trailing strip S2 is superimposed on the surface of the tail portion of the preceding strip S1, the elevating cylinder 220 of the heating press 200 is operated to move the compression plate 210 to the trailing strip S2. It is lowered with a pressure of a set size toward the surface of the head part.

As the compression plate 210 descends, the pressure of the compression plate 210 is transmitted to the heating plate 230 , and the heating plate 230 has the head portion of the trailing strip S2 at the junction BA of the tail portion of the preceding strip S1 . The bonding portion BA is compressed while applying a pressure of a set size to the , and at the same time, the bonding portion BA is heated at a set temperature and for a set time to cure the bonding solvent to bond.

At this time, since the bonding solvent consists of a solvent in which an acrylic adhesive for providing adhesive strength and silica particles (powder) for maintaining a constant distance between the bonding portions BA are mixed, the head of the trailing strip S2 is the preceding strip. The joint portion BA of the tail portion of ( S1 ) may be uniformly joined.

Although the present disclosure has been described through preferred embodiments as described above, the present invention is not limited thereto, and various modifications and variations are possible without departing from the scope of the claims set forth below.
