DETAILED DESCRIPTION OF THE INVENTION
Embodiments according to the present invention will be described below with reference to the drawings. FIG. 1 is a flowchart for explaining a method for manufacturing a laminate film according to the first embodiment. The manufacturing method of the present embodiment includes a laminating tape drawing step S110, a laminating tape adsorption fixing step S120, and a laminating tape cutting step S130, and is performed as follows.
[0015]
First, the laminate tape is pulled out with a certain dimension along the longitudinal direction (step S110), and then one side of the laminate tape that has been pulled out with a certain dimension is two-dimensionally adsorbed and fixed at a plurality of locations (step S120). Thereafter, the fixed laminate tape is cut (step S130) to obtain a laminate film having a fixed length in the longitudinal direction. After the obtained laminate film is conveyed, if steps S110 to S130 are repeated, a laminate film having a constant dimension can be obtained continuously.
[0016]
Steps S110 to S130 can be performed using the apparatus shown in FIG. FIG. 2 schematically shows a tape drawing device 10 that pulls out the laminate tape 100, a suction table 20 that sucks and fixes the laminate tape 100, and a tape cutting device 30 that cuts the laminate tape 100. In the present embodiment, the tape drawing device 10, the suction table 20, and the tape cutting device 30 are sequentially installed from the front to the rear ( downstream to upstream ) in the direction 50 in which the laminate tape 100 is drawn.
[0017]
The tape drawing device 10 includes a tape suction unit 12 that sucks the laminate tape 100 and a uniaxial robot 14 that moves the tape suction unit 12 along the longitudinal direction 16 of the laminate tape 100. Step S110 can be performed using the tape drawing device 10, and may be performed, for example, according to the flowchart shown in FIG. In this embodiment, a tape (tape width) in which an adhesive layer (for example, a polyolefin-based adhesive) is formed on an insulating tape layer (for example, a base film of polyethylene terephthalate resin) formed of an insulating material as the laminate tape 100. For example, 430 to 520 mm).
[0018]
First, the tape adsorbing portion 12 is moved above the portion 50a on the front side in the pulling direction 50 of the laminated tape 100 to be pulled out (step S111). The movement of the tape adsorbing unit 12 is performed by the uniaxial robot 14, and the tape drawing device 10 is arranged at the position of the tape drawing device 10 ′ by this movement. Note that the portion 50 a of the laminated tape 100 that is pulled out can be adsorbed to the adsorbing portion 36 of the tape cutting device 30, for example.
[0019]
Next, the suction portion 12 is lowered toward the laminate tape 100 by the cylinder 13 that moves the suction portion 12 up and down (step S112), and then the laminate tape 100 is sucked by the suction portion 12 (step S113). Whether the suction unit 12 is reliably sucking the laminate tape 100 may be confirmed by a vacuum switch (not shown) provided in a vacuum generator connected to the suction unit 12.
[0020]
Next, the suction part 12 is raised by the cylinder 13 with the laminate tape 100 being sucked (step S114). When the front portion 50a of the laminating tape 100 in the pulling direction is adsorbed by the adsorption unit 36 of the tape cutting device 30, the adsorption by the adsorption unit 36 of the tape cutting device 30 may be canceled when performing step S114. preferable. Thereafter, the suction unit 12 is moved forward by a distance of a fixed dimension L by the uniaxial robot 14 in the pulling direction 50 (step S115). When the steps S111 to S115 are performed in this way, the laminate tape 100 can be pulled out along the longitudinal direction 16 by a certain dimension L. Note that the tape drawing device 10 makes one reciprocation along the longitudinal direction 16 of the laminate tape 100 during the steps S111 to S115. Note that step S114 can be omitted if the suction unit 12 can be moved forward in the pulling direction 50 without performing step S114.
[0021]
Next, the drawn-out laminate tape 100 is placed on the suction table 20 by lowering the suction portion 12 of the drawer device 10. FIG. 4 schematically shows the upper surface of the suction table 20. A plurality of suction holes 22 are two-dimensionally arranged on the suction table 20, and for example, about 1000 or more suction holes 22 are provided. In the present embodiment, a plurality of suction holes 22 are arranged in the suction table 20 in an arrangement pattern that can be handled regardless of whether the width of the laminate tape 100 is W1 or W2. For example, the unnecessary suction holes 22 may be covered. It can be used according to the size of the laminate tape 100 by covering with a plastic tape (for example, plastic tape).
[0022]
After the laminating tape 100 is placed on the suction table 20, the laminating tape 100 is sucked through each of the plurality of suction holes 22, and the laminating tape 100 is sucked and fixed onto the suction table 20. At the stage of this suction fixation, the front portion 50a of the laminate tape 100 to be drawn next is sucked by the suction portion 36 of the tape cutting device 30.
[0023]
After confirming that the laminating tape 100 is sucked and fixed on the suction table 20 with a vacuum switch, the suction by the suction part 12 of the drawer device 10 is canceled and the suction part 12 is kept waiting or the suction part 12 is Raise. Next, after confirming that the front portion 50a of the laminating tape 100 in the pulling direction is adsorbed by the adsorbing portion 36 of the tape cutting device 30, the cutting process (step S130) of the laminating tape 100 is performed.
[0024]
FIG. 5 shows the configuration of the tape cutting device 30 when viewed from the rear in the pulling direction 50 toward the front. The tape cutting device 30 has an upper blade 32 and a lower blade 34 as cutting blades, and cuts the laminate tape 100 by lowering the upper blade 32 and engaging with the lower blade 34. Refer to FIG. 2 again. As shown in FIG. 2, a suction portion 36 that sucks the front portion 50 a of the laminate tape 100 to be pulled out next is provided on the rear side (upstream) of the lower blade 34 in the pulling direction 50. By adsorbing the laminate tape 100, the laminate tape 100 to be drawn next can be prevented from curling even after the laminate tape 100 is cut by the upper blade 32 and the lower blade.
[0025]
In the cutting step (S130), first, the tape press 38 for pressing the periphery of the cut portion of the laminate tape 100 is lowered to fix the laminate tape 100 on the lower blade 34, and then the upper blade 32 is lowered to laminate. The tape 100 is cut. Since the cut laminate tape 100 is adsorbed by the suction table 20 and the adsorbing portion 36 of the tape cutting device 30, it remains fixed without curling. After cutting the laminate tape 100, the upper blade 32 and the tape presser are raised and returned to the same position as before the cutting. In order to perform the cutting process safely, it is preferable that a safety cover 40 is attached to the tape cutting device 30.
[0026]
After the cutting step, the suction of the suction table 20 is released, and a laminate film having a certain size can be transported from the suction table 20 using a transport device (not shown). After the laminate film is conveyed, the tape adsorbing unit 16 of the tape drawing device 10 is moved above the adsorbing unit 36 of the cutting device 30 and steps S110 to S130 are repeated again. A film can be obtained. The laminate film thus obtained can be used, for example, as a laminate film for a flat wiring body by being overlaid with a wiring film having a copper foil pattern on an insulating film layer. The present invention can be widely applied not only when producing a laminate film for a flat wiring body but also when continuously cutting and supplying a two-layer tape (laminate tape) that easily curls, for example. .
[0027]
【The invention's effect】
According to the present invention, one side of the laminate tape drawn out by a certain size is two-dimensionally adsorbed and fixed at the front part in the pulling direction from the cutting part, and at the rear of the cutting part by the tape adsorbing part of the tape cutting device. By adsorbing the portion, it is possible to prevent the occurrence of curling before and after the cut portion, so that it is possible to manufacture a laminate film having a certain size more efficiently than the prior art.
