6 is a plan view of a square coil fabricated by an antenna manufacturing apparatus according to an embodiment of the present invention.

1 to 6, an antenna manufacturing apparatus 100 using a square coil 10 according to an embodiment of the present invention includes a frame 110, a body 120, a supply support 130, a transfer unit 140 A pattern setting unit 150, a finishing processing unit 160, and a rotation unit 170.

The frame 110 supports or connects the body 120, the supply support 130, the transfer unit 140, the pattern setting unit 150, and the finishing unit 160. Particularly, the frame 110 is raised on the work table 22, and the work table 22 is placed on the sheet 20.

At this time, the sheet 20 is bonded to the flat coil 10, the sheet 20 is made of an insulating material, and the flat coil 10 is applied to an antenna of a cellular phone. Accordingly, the rectangular coil 10 is made of a conductive material. In addition, the flat coil 10 is formed of a thin plate.

In particular, the rectangular coil 10 is formed to have a relatively long length in order to secure a permissible current value. Since the sheet 20 has a limited planar area, the rectangular coil 10 may be circular Are arranged along a polygonal locus (pattern). At this time, the rectangular coils 10 are spaced apart from each other by a predetermined distance to prevent contact.

In addition, the body 120 is positioned on the upper side of the frame 110, particularly, on the upper side of the work table 22.

Of course, the frame 110 and the body 120 can be deformed into various shapes.

The supply supporter 130 is connected to the body 120 to support the coil roll 12 in the roll state for supplying the flat coil 10 and to supply the coil roll 12 in the sheet 20 direction.

In detail, the supply support 130 includes a rotation roller 132 and a sensor member 134. [

The rotary roller 132 is supported underneath the coil roll 12 in a circumscribed manner and is rotatably provided in the body 120 to rotate the coil roll 12 in order to supply the rectangular coil 10. [ In particular, the rotating rollers 132 are made of at least one pair in order to stably support the coil rolls 12.

At this time, the rotating rollers 132 are connected to each other by the power transmitting member 135. Here, the power transmitting member 135 may be variously applied to a chain or a belt.

In addition, the power transmitting member 135 is connected to the driving motor 133. [ Therefore, when the driving motor 133 is driven, the rotating roller 132 is rotated in the same direction by the power transmitting member 135. [ Thus, the coil roll 12 can be unrolled and provided to the sheet 20 side.

One or more sensor members 134 are provided on the body 120 to detect whether or not the flat coil 10 is warped or not to be conveyed from the coil roll 12 to the sheet 20 side, . That is, when the sensor member 134 senses warpage (loose state) of the sensor member 134 to be conveyed downward, the signal is transmitted to the driving motor 133 so as to increase the rotation speed of the rotation roller 132.

The conveying unit 140 is disposed on the body 120 and rotates the flat coil 10 conveyed while being unwound from the coil roll 12 on the rotating roller 132 of the supply supporting unit 130 to the sheet placed on the work table 22, So as to be placed so as to be interviewed with the user. At this time, the transfer unit 140 may be a nozzle (not shown) provided in the body 120 or an adhesive ultrasonic oscillator 162 to be described later, and may be an adhesive guide horn (not shown) provided at the end of the adhesive ultrasonic oscillator 162 163 so as to allow the flat coil 10 to be transported downward in the sheet 20 direction.

In particular, as the square coil 10 is transported in the downward direction, it falls down by its own weight.

The pattern setting unit 150 serves to change the position of the body 120 in order to guide the conveying unit 140 along the setting pattern of the flat coil 10 on the sheet 20.

That is, when the rectangular coil 10 is patterned at a diameter gradually increasing along the circular trace on the sheet 20, the transferring portion 140 follows the circular trajectory gradually increasing in diameter by the pattern setting portion 150 .

Here, the pattern setting unit 150 includes a support beam 152, a back and forth moving member 154, and a left and right moving member 158.

The support beam 152 is provided on the frame 110 so as to be erected. The support beam 152 can be deformed into various shapes. Of course, the support beam 152 may be the frame 110 itself.

The back and forth moving member 154 connects and supports the body 120 to the support beam 152. Thus, the body 120 maintains a distance from the seat 20. [

In addition, the back and forth moving member 154 serves to allow the body 120 to reciprocate linearly in a direction perpendicular to the support beam 152. 1, the body 120 can be linearly reciprocated in the forward and backward directions by the forward / backward moving member 154. Here, the back and forth movable member 154 can be variously applied to an LM guide, a cylinder, or the like.

Further, the base plate 156 is provided on the frame 110, and fixes the work table 22. Of course, the base plate 156 can be deformed into various shapes.

The left and right movable member 158 serves to allow the base plate 156 to linearly reciprocate with respect to the frame 110 in a direction perpendicular to the linear reciprocating direction of the body 120. 1, the body 120 can be linearly reciprocated in the left-right direction by the left-right shifting member 158. As shown in FIG. Here, the left and right movable member 158 is applicable to various types such as an LM guide or a cylinder.

In particular, the back-and-forth shifting member 154 and the left-and-right shifting member 158 can be controlled to move mutually by a set value.

The finishing unit 160 serves to fix the flat coil 10 to the sheet 20 and to keep the flat coil 10 in the sheet 20 to be flattened.

To this end, the finisher 160 includes an adhesive ultrasonic oscillator 162 and a planarization ultrasonic oscillator 164.

At this time, the bonded ultrasonic oscillator 162 is preceded and the planarization ultrasonic oscillator 164 is trailing. Precisely, the working material on which the sheet 20 is placed is moved to the left (viewed in FIG. 1) by the left and right moving member 158. However, for convenience, the bonding ultrasonic oscillator 162 precedes (precedes) the planarizing ultrasonic oscillator 164 ) Is to be traced (succeeding).

The adhesive ultrasonic oscillator 162 is provided in the body 120 and functions to repeatedly oscillate the ultrasonic waves in the rectangular coil 10 divided into a straight section and a direction change section in a state of being in contact with the sheet 20. [ At this time, the adhesive ultrasonic oscillator 162 generates frictional heat by oscillating the ultrasonic wave immediately after the flat coil 10 comes into contact with the sheet 20, thereby inducing adhesion between the sheet 20 and the flat coil 10.

Accordingly, the bonded ultrasonic oscillator 162 may be disposed adjacent to the transfer unit 140 or include the transfer unit 140. In particular, the adhesive ultrasonic oscillator 162 is provided at an end thereof with an adhesive guide horn 163 for oscillating ultrasonic waves, and the transfer unit 140 is provided in the adhesive guide horn 163. Immediately after the flat rectangular coil 10 is brought into contact with the sheet 20 by the conveyance unit 140, the bonded ultrasonic oscillator 162 oscillates ultrasonic waves to generate the flat rectangular coil 10 on the sheet 20 .

At this time, the sheet 20 and the square coil 10 may form an adhesive layer or an insulating layer to be partially melted, respectively, so that the sheet 20 and the flat coil 10 can be firmly adhered to each other.

In addition, the planarization ultrasonic oscillator 164 follows the adhesive ultrasonic oscillator 162 when the sheet 20 is moved to the left in FIG. 1 by the operation of the left and right movable member 158. When the back and forth moving member 154 is in operation, the bonded ultrasonic oscillator 162 and the flattening ultrasonic oscillator 164 are moved in the same direction in parallel.

In particular, the planarization ultrasonic oscillator 164 is provided in the body 120 and functions to planarize the rectangular coil 10 by repeatedly oscillating the ultrasonic waves on the flat coil 10 bonded to the sheet 20.

In particular, the planarization ultrasonic oscillator 164 is provided with a planarization guide horn 165 at its lower end, and the planarization guide horn 165 serves to guide the ultrasonic oscillation.

Of course, the planarization ultrasonic oscillator 164 and the planarization guide hone 165 can be modified into various shapes.

On the other hand, when the flat coil 10 is patterned along the circular trace on the sheet 20, and the body 120 and the bonded ultrasonic oscillator 172 are moved along the patterning locus while facing the same direction, The twist may be generated while being supplied to the tweezers 20.

To prevent this, a rotation unit 170 is provided.

Particularly, the body 120 is connected to and supported by the bracket 122, and the bracket 122 is connected to the frame 110 through the back and forth moving member 154. Of course, the bracket 122 can be deformed into various shapes.

The rotation unit 170 is provided to rotate the body 120 in the circumferential direction with respect to the frame 110 and rotates the transfer unit 140 along the locus of the rectangular coil 10 patterned on the sheet 20 Thereby preventing the square coil 10 supplied to the sheet 20 from twisting.

In addition, the rotation unit 170 includes a main member 172, a driven member 174, a connecting member 176, and an operation motor 178.

The driven member 172 is rotatably mounted on one side of the bracket 122 and the driven member 174 is fixed to the body 120 and is rotatably provided on the other side of the bracket 122.

At this time, the main moving member 172 and the driven member 174 can be variously applied to gears, wheels, and the like.

The connecting member 176 connects the main moving member 172 and the driven member 174, and can be variously applied to a chain or a belt.

Further, the actuating motor 178 transmits rotational force to the main moving member 172.

The adhesive ultrasonic oscillator 162 and the planarization ultrasonic oscillator 164 constituting the body 120 and the finish processing unit 160 can be rotated when the operation motor 178 operates.

Accordingly, when the flat coil 10 patterned on the sheet 20 is moved along the circumferential locus and continuously supplied, the operation motor 178 moves the body 120, the transfer unit 140, and the finishing unit 160 by a set value, In the circumferential direction. Thus, the square coil 10 is supplied to the sheet 20 while being prevented from being twisted.

At this time, the operation motor 178 can be applied as a stepping motor so that the body 120 can be rotated in both directions along the circumferential direction.
