[0035] Hereinafter, referring to FIGS. 1 to 4, a reel-to-reel circuit board manufacturing apparatus according to an embodiment of the present disclosure will be described below.

[0036] FIG. 1 is a diagram showing a reel-to-reel circuit board manufacturing apparatus according to an embodiment of the present disclosure seen from above. FIG. 2 is a cross-sectional view showing a clamp taken along line A-A′ of FIG. 1 according to an embodiment of the present disclosure. FIG. 3 is a diagram illustrating a vertical movement structure of one clamp arm due to an obstacle, according to an embodiment of the present disclosure. FIG. 4 is a diagram illustrating a vertical movement structure of another clamp arm when a material is moved from the state shown in FIG. 3.

[0037] Referring to FIGS. 1 to 4, the reel-to-reel circuit board manufacturing apparatus according to an embodiment of the present disclosure includes a material 30 that is moved while being unwound and wound by an uncoiler 10 and a recoiler 20, and a clamp 100 that is arranged so that a lengthwise direction thereof matches a width direction of the material 30 and fixes the material 30. The clamp 100 includes first and second clamps 110 and 120 provided at opposite ends thereof, and a first-and-second clamp linkage 130 provided between the first and second clamps 110 and 120.

[0038] The clamp 100 may fix the material 30 from the opposite ends in the width direction of the material 30. Because the material 30 is moved while the opposite ends in the width direction thereof are fixed by the clamp 100, the material may be stably moved and a plating process may be stably performed through driving, to thereby improve efficiency of manufacturing the circuit board. A plurality of clamps 100 may be arranged along a proceeding direction of the material 30 at constant intervals.

[0039] The first and second clamps 110 and 120 fixing the opposite ends of the material 30 may be connected to each other under the material through the first-and-second clamp linkage 130. The first-and-second clamp linkage 130 is provided under the material 30 and support a middle part of the material 30.

[0040] According to an embodiment of the present disclosure, as shown in FIG. 2, the first-and-second clamp linkage 130 may include an elastic body 140. The elastic body 140 provides elasticity between the first and second clamps 110 and 120 so that the elasticity may be applied in the direction in which the first and second clamps 110 and 120 are away from each other, and thus, the material 30 may be held from opposite sides without forming crinkles.

[0041] Referring to FIG. 3, the clamp 100 may include first and second clamp arms 111 and 121 that are connected to the clamp 100 to fix the clamp 100. The first clamp arm 111 may be connected to the first clamp 110, and the second clamp arm 121 may be connected to the second clamp 120.

[0042] The first and second clamp arms 111 and 121 move the clamp 100 so that the material 30 coupled to the clamp 100 may be moved in the proceeding direction.

[0043] According to an embodiment of the present disclosure, as shown in FIG. 3, the first and second clamp arms 111 and 121 may be attached to/detached from the clamp 100. Here, the first and second clamp arms 111 and 121 may be attached to/detached from the clamp 100 while moving in the direction perpendicular to the clamp 100.

[0044] As described above, the first and second clamp arms 111 and 121 may have attachable/detachable structures so as to avoid an obstacle A such as a piping or a wiring. Referring to FIGS. 3 and 4, the first clamp arm 111 and the second clamp arm 121 may be separately attached/detached. That is, when an obstacle exists above one side of the material 30, the first clamp arm 111 at one side of the material 30 may be only separated from the first clamp 110. Also, when an obstacle exists above the other side of the material 30, the second clamp arm 121 at the other side of the material 30 may be only separated from the second clamp 120.

[0045] According to an embodiment of the present disclosure, a clamp support 200 may be further provided along the direction in which the material 30 proceeds. The clamp support 200 may be connected to the clamp 100 and supports the clamp 100 to position the clamp 100.

[0046] Referring to FIGS. 3 and 4, the clamp support 200 may further include a rail portion 210 that is formed along the proceeding direction of the material 30. Here, the clamp 100 is connected to the rail portion 210, and may be moved along the rail portion 210.

[0047] When the first and second clamp arms 111 and 121 are moved in the proceeding direction, the clamp 100 connected to the clamp arms 111 and 121 may be moved in the proceeding direction along the rail portion 210. Here, the material 30 fixed by the clamp 100 may be also moved in the proceeding direction.

[0048] As described above, when the obstacle A approaches the first and second clamp arms 111 and 121 moving along the rail portion 210, the first and second clamp arms 111 and 121 are separated from the first and second clamps 110 and 120. In addition, when the obstacle A passes by, the first and second clamp arms 111 and 121 are recombined with the first and second clamps 110 and 120. Due to the above structure, the material 30 may be stably moved in the proceeding direction.

[0049] Hereinafter, a reel-to-reel circuit board manufacturing apparatus according to another embodiment of the present disclosure will be described with reference to FIG. 5.

[0050] FIG. 5 is a diagram illustrating a structure of adjusting a length of a clamp arm according to another embodiment of the present disclosure.

[0051] Referring to FIG. 5, in the reel-to-reel circuit board manufacturing apparatus according to another embodiment of the present disclosure, when a clamp arm 121′ is separated from the clamp 120, a length of the clamp arm 121′ may be variable. As such, a length L2 of the clamp arm 121′ separated from the clamp may be less than a length L1 of the second clamp arm 121 coupled to the clamp.

[0052] In particular, a lower end of the clamp arm 121′ may be moved upward, and an upper end of the clamp arm 121′ may be maintained at the same position as that before the separation. That is, even when the clamp arm 121′ is separated from the clamp 100, the upper end of the clamp arm 121′ is maintained constantly. Thus, heights H of the upper ends in a plurality of clamp arms 111, 121, and 121′ are equal to one another, and it may be designed so that the clamp arm 121′ may be attached to/detached from the clamp 100 while a moving portion (not shown) that is connected to the upper ends of the plurality of clamp arms 111, 121, and 121′ and moves the clamp arms in the proceeding direction is maintained to be connected to the clamp arms 111, 121, and 121′.

[0053] Hereinafter, a clamp having a magnet portion formed thereon according to another embodiment of the present disclosure will be described below with reference to FIG. 6.

[0054] FIG. 6 is a diagram showing a clamp on which a magnet portion is formed, according to another embodiment of the present disclosure.

[0055] Referring to FIG. 6, in a reel-to-reel circuit board manufacturing apparatus according to another embodiment of the present disclosure, the first-and-second clamp linkage 130 has a magnet portion 140′ so as to provide a tension between the first and second clamps 110 and 120. The magnet portion 140′ may have a structure including a magnetic material such as an electromagnet. As such, information about a degree of tension required by a user is transferred to the magnet portion 140′ so that a tensile force is applied due to a magnetic force between the first and second clamps 110 and 120, and accordingly, a degree of straightening the material 30 fixed by the first and second clamps 110 and 120 may be adjusted.

[0056] The present disclosure is described above with reference to the embodiments shown in the drawings, but these embodiments are merely examples. One of ordinary skill in the art would understand that various modifications and other equivalent embodiments may be made from the embodiments. Therefore, the scope sought to be protected of the disclosure shall be defined by the appended claims.

[0058] Furthermore, the connecting lines or connectors shown in the drawings are intended to represent example functional relationships and/or physical or logical couplings between the various elements. It should be noted that many alternative or additional functional relationships, physical connections, or logical connections may be present in a practical device. Moreover, no item or component is essential to the practice of the disclosure unless the element is specifically described as “essential” or “critical”.
