Description

  The present invention relates to a winding device used for manufacturing an aluminum electrolytic capacitor, a battery or the like, which is an electronic component used in an electronic device, and a method thereof.

  A conventional electronic component winding device will be described with reference to the drawings.

  7 and 8 are conceptual diagrams of the configuration of a winding device for winding a conventional belt-shaped material.

  In the winding device of FIG. 7, the belt-shaped material 1 supplied by a reel or the like is unwound by the unwinding mechanism 2 and is driven by rotational power (not shown) while applying tension by the dancer roller 3. A winding element is formed by the winding shaft 4.

  Further, the winding device includes a cutting mechanism 5 that cuts the member into a predetermined length, and a tip feeding mechanism 6 that holds the tip of the strip-shaped material after cutting and feeds it to the winding shaft 4.

  In addition to the winding device of FIG. 7, the winding device of FIG. 8 includes a fixed guide 7 that positions the band-shaped material at a specified position in the width direction.

  FIG. 9A is a perspective view showing the concept of the fixed guide 7, and FIG. 9B is a perspective view of the flanged roller 8 that performs the same function as the fixed guide 7.

  FIG. 6 is a conceptual diagram showing an example of a winding element.

JP 2000-68170 A

  However, in the winding device shown in FIG. 7, if the tension of the dancer roller 3 is increased, the winding deviation 10 of the winding element 9 as shown in FIG. 6 can be reduced, but the winding deviation can be completely prevented. However, if the tension is increased, the band-shaped material may be destroyed.

  Furthermore, if the unwinding position of the belt-shaped material supplied by a reel or the like is deviated, there is a problem that the deviation is directly unwound.

  Further, in the formation of a large number of winding elements, there has been a problem that winding deviation accumulates and the winding deviation cannot be regulated.

  Further, in another winding device shown in FIG. 8, the winding deviation can be regulated by the fixed guide 7, but dust is generated by rubbing with the fixed guide 7 during the transfer of the belt-like material, and the dust is wound up. There is a possibility that the winding element will be caught in the element and the characteristic of the winding element (short circuit defect, etc.) may occur.

  Further, the rubbing may cause scratches in the belt-like material, and the scratches may cause defective characteristics (such as short-circuit defects) of the winding element.

  The generation of dust and scratches due to rubbing during the transfer of the belt-shaped material occurs also in the fixed guide 7 shown in FIG. 9A and also in the roller 8 with the flange shown in FIG. 9B.

After the state of b), the state returns to the state of FIG.

  Then, after winding the belt-shaped material 1 having a predetermined length with the winding shaft 4, the belt-shaped material 1 is gripped by the tip delivery mechanism 6 that has returned to the initial position, and the belt-shaped material 1 is cut by the cutting mechanism 5.

  Since the belt-like material end on the winding element side is free after cutting, after fixing the belt-like material end to the winding element by using a tape attaching mechanism or the like (not shown), the winding element is taken from the winding shaft 4. When the is removed, the winding element is completed.

  The gripping mechanism 12 on the transport path moves toward the winding shaft 4 following the movement of the strip-shaped material 1 while the strip-shaped material 1 is being wound around the winding shaft 4, but the winding shaft 4 has a predetermined length. After the tip delivery mechanism 6 grips the strip-shaped material 1, the gripping mechanism 12 is opened at that position.

  This positioning mechanism includes an openable guide 16 and a suction plate 18 that position the belt-shaped material 1 at a specified position in the width direction.

  In FIG. 4, the band-like material 1 and the front side of the openable guide 16 are partially cut away for easy understanding.

  The suction plate 18 is movable in the vertical direction as a whole by the slider 19, and is installed at a position lowered from the transport path of the belt-like material 1 except when performing a positioning operation.

  The suction plate 18 can be rotated by a lever 20 within a certain range around the fulcrum pin 21, and can be moved by a slider 22 within a certain range in the width direction of the band-shaped material 1.

  Further, the suction plate 18 tends to return to the center position in the rotational direction and the width direction by the elastic force of the leaf spring 25 fixed to the housing 23 with screws 24.

  Further, a vacuum pipe 26 is connected to the suction plate 18 so that the belt-like material 1 can be sucked through a hole on the upper surface of the suction plate 18.

  According to this positioning mechanism, even a thin belt-like material can be stably sucked and held by the suction plate during the positioning operation.

  Further, in this positioning mechanism, since the suction plate 18 is movable in the rotation and width direction, the belt-like material 1 is positioned by the openable guide while being sucked and held by the suction plate 18, and the belt-like material 1 is held by the gripping mechanism. It can be gripped again.

  According to this operation, the band-shaped material can be positioned stably, and the band-shaped material 1 is not rubbed on the suction plate 18 during the positioning operation, so that the band-shaped material can be positioned without generation of dust and scratches. .

  Furthermore, according to this positioning mechanism, the belt-like material 1 can be stably adsorbed and held, so that the tip delivery mechanism can be opened at the timing shown in FIG. 2B of the positioning operation described in the first embodiment. .

  As a result, the band-shaped material 1 can be positioned with only the open / close guide of the positioning mechanism without being affected by the gripping of the tip-feeding mechanism, compared with the case where the leading-end feeding mechanism performs the positioning operation with the band-shaped material 1 gripped. Accurate positioning can be performed.

  In FIG. 5, the tension generating mechanism includes a pulley 28 driven by a servo motor 27, and a linear member 29 having one end wound up by the pulley and the other end connected to the gripping mechanism.

  Thus, unlike a spring having a constant elastic coefficient, the tension can be made variable according to the difference in the belt-like material 1 using the torque control of the servo motor, and the tension during rotation of the winding shaft can be made variable. It has the effect of.

  The tension control in the winding device is an important point related to the quality of the winding element, and it is very effective to make the control variable.

  Furthermore, when the winding shaft driven by rotational power accelerates and decelerates, the tension applied to the belt-like material 1 changes due to the inertia of the gripping mechanism and the dancer roller, the viscous resistance of the roller bearing, etc. The optimum tension differs in each state at the time and at the constant speed, but with this configuration, the tension control on the belt-like material 1 can be performed by controlling the torque of the servo motor in synchronization with the rotational power of the winding shaft. is there.
