Description

  The present invention relates to a flat electronic component manufacturing apparatus, and more particularly to a flat electronic component manufacturing apparatus such as a flat battery or a flat capacitor.

  Conventionally, flat batteries and flat capacitors for mobile phones have been manufactured by winding strip electrode members such as positive and negative electrode sheets and separators around a flat core. As such a technique, for example, Japanese Patent Laid-Open No. 2002-270213 “A winding method and a winding device for a flat element for a flat electronic component”, Japanese Patent Laid-Open No. 2001-229918, “A winder device for a belt-shaped material”, JP-A-2001-202986 “Spiral electrode group winding method and apparatus and battery using the same”, and JP-A-2001-57242 “Winding apparatus and winding method” can be mentioned.

  In these techniques, for example, all belt-shaped electrode members are supplied as rolls and wound around a core to produce a flat electronic component, and the core is formed in the center of a separator extended to one side. , And the electrode member arranged on the left and right around this is wound up.

JP 2002-270213 A JP 2001-229918 A Japanese Patent Laid-Open No. 2001-202986 Japanese Patent Laid-Open No. 2001-57242

However, the conventional technique has the following problems.
That is, electronic parts such as batteries and capacitors have different capacities depending on the contact area between the electrode plates. Further, since the distance between the electrode plates also changes the capacity, it is necessary to control so as not to cause winding unevenness such as “twist” or winding disturbance. Further, if the electrode plate comes out of contact with the separator, it does not function as a battery in the first place. Therefore, a positioning mechanism and a winding unevenness prevention mechanism are important design items of the apparatus.

  However, in the conventional method of pulling out a member from up to four rolls (two supply rolls for the strip electrode plate and two supply rolls for the strip separator), the roll and the winding unit are connected by the member. There was a problem that positioning was difficult on the way. Further, when the positioning mechanism is provided, the roll, the winding unit, and the positioning unit are basically aligned on the same straight line, which causes a problem that the apparatus becomes large and complicated. In addition, as a mechanism for preventing uneven winding, there is a mechanism that feeds out a belt-like member that follows the change in the winding speed by a servo motor or the like. However, if a servo motor is used, the cost of the device becomes extremely high. there were.

  In addition, even if there is, for example, electrode member paint baldness on a part of the roll, it is practically impossible to remove the defective part during the operation of the apparatus, and thus there is a problem that the yield cannot be prevented from being lowered. .

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The Li ion battery manufacturing apparatus 100 includes a storage unit 101 that stores an electrode member D (see FIG. 9 described later), a positioning unit 102 that positions the electrode member D transferred from the storage unit 101, and a positioning unit 102. A feeding unit 103 that feeds the electrode member D positioned in step S3 for winding, a winding unit 104 that winds up the electrode member D sent from the sending unit 103, a storage unit 101-a positioning unit 102, and a positioning unit. 102 and a transfer unit 105 that reciprocates between the delivery unit 103 and transfers the electrode member D.

  The storage unit 101 (see FIG. 3) is provided with two stockers 111 that can take out the strip-shaped electrode members D that are aligned and stacked from the upper part at a predetermined distance in the longitudinal direction of the electrode members D. The stocker 111 includes a positive electrode stocker 111a on which the positive electrode member Da is loaded and a negative electrode stocker 111b on which the negative electrode member Db is loaded. FIG. 9 is an explanatory diagram showing the configuration of the battery. The positive electrode member Da is a strip-shaped member obtained by coating a positive electrode active material on an aluminum strip metal foil, and the negative electrode member Db is a strip-shaped member obtained by coating a negative electrode active material on a copper strip metal foil. It is a member. Each metal foil end is provided with long and thin electrode terminals Ta and Tb.

  Since the stocker 111 is stacked with the strip-shaped electrode members D aligned, the cutout grooves 112 are provided so that the electrode terminals Ta and Tb protruding from the ends of the electrode members D do not interfere with the stacking. Further, the long side of one side of the stocker 111 is detachable so that the electrode members D can be bundled in advance and placed from the short direction (see FIG. 3). In addition, since the positioning is performed by the positioning unit 102, the stocker 111 may be stacked roughly roughly so that the electrode terminals Ta and Tb are at the same position.

  The positioning unit 102 (see FIG. 4) includes positioning bases 121 (a positive positioning base 121a and a negative positioning base 121b) on which the electrode members D taken out and transferred from the stocker 111 are placed. A longitudinal positioning belt 122 of the electrode member D spanned in the longitudinal direction of the pedestal 121, a regulating plate 123 that regulates and positions the position of the electrode member D in the short direction, and an electrode terminal Ta or Tb are engaged. And a locking body 124 for stopping and cueing. In positioning, first, the electrode members D are respectively placed on the positioning bases 121 and moved in the longitudinal direction by the positioning belt 122 until the electrode members D are stopped by the locking bodies 124, and then short by the restriction plate 123. Position the direction. The electrode member D is positioned in both the longitudinal direction and the lateral direction by the regulating plate 123 and the locking body 124, and is transferred to the base of the delivery unit 103 while being positioned.

  The delivery unit 103 (see FIG. 5) is provided with a delivery base 131 (a positive electrode delivery base 131a and a negative electrode delivery base 131b) on which the electrode member D positioned by the positioning unit 102 is placed. Each of the pedestals 131 has a plurality of minute air holes, and is configured to increase the adhesion of the electrode member D by suction from the back side by vacuum. In addition, a pair roller 132 that feeds the electrode member D from above and below in the longitudinal direction is provided at the ends of the two delivery bases 131, and a magnetic torque control device 133 is applied to one of the pair rollers 132 to wind the electrode member D. It is set as the structure which provides substantially constant drag with respect to. Due to the magnetic torque control device 133, the pair roller 132, and the air holes, the electrode member D can be sent out with high accuracy while the positional relationship of the electrode member D is maintained, and can be wound up.

  Examples of the magnetic torque control device include so-called perm torque (PERMA-TORK (PERMA-TORK is a registered trademark of Magnetic Power Systems Inc., USA)). This is composed of two magnets and one disk, and the disk is fixed to the shaft and held by a bearing. When the disk rotates, the two magnets try to block the rotation of the disk, and its features include a non-contact structure that eliminates the need for an external power supply, and easy torque setting and excellent repeatability. it can. Therefore, tension can be adjusted with an inexpensive and compact device configuration.

  Further, the positive electrode delivery base 131 a is configured to move on the rail 134 by the cylinder 135 and slide into the lower part of the negative electrode delivery base 131 b. Further, the positive electrode delivery base 131a has a separator hook 136 that hooks the separator at the tip thereof, and the separator S is inserted from below the rear part of the negative electrode delivery base 131b as the positive electrode delivery base 131a moves.

  The winding unit 104 (see FIG. 6) includes two flat sandwiching plates 141a and 141b that form a winding core 141, and a negative electrode member Db-separator S-positive electrode inserted at a winding position. A clamp roller 142 that binds the electrode member Da, a fixed roller 143, and a dancer roller 144 that moves up and down in synchronization with the rotation of the winding core 141 in order to absorb winding speed unevenness caused by the rotation of the winding core 141. .

  The sandwiching plates 141a and 141b have a shape in which the surface on the side (inner side) sandwiching the bundle is flat and the surface on the side (outer side) around which the bundle is wound is inflated. Thus, by providing a bulge on the outer side, it is possible to prevent winding unevenness and positional deviation resulting from a rapidly changing winding speed. Further, a presser roller 145 is disposed below the core 141, and the member is pressed to the outside of the core with a predetermined pressure. Further, the rotation speed of the winding core 141 is constant, the change in the winding speed based on the rotation is absorbed by the dancer roller 144, and the feeding speed of the electrode member D and the separator S in the feeding section 103 is constant. The constant delivery speed means that the tension can be kept within a desired range, which can prevent winding disorder and winding irregularities and make it possible to manufacture batteries with consistent quality. means.

  Conventionally, for example, complicated control for adjusting the feed speed of the member by feeding back the displacement of the core 141 with a servo motor is necessary. However, the Li ion battery manufacturing apparatus 100 absorbs the displacement with the dancer roller 144. As a result, the apparatus can be simplified.

  The Li ion battery manufacturing apparatus 100 includes a separator roll 146 above the delivery unit 103 and a tension chuck 147 below the winding unit 104. The separator roll 146 is a separator supply unit around which the separator S is wound. In this apparatus, the separator roll 146 is the only roll-shaped member supply unit as a constituent member of the battery. This is based on the reason that the separator S is an extremely thin and soft ion-permeable film, so that it is difficult to align it in a strip shape like the electrode member D, so that it is supplied as a roll. However, since supply of two rolls complicates positioning control and apparatus configuration, this apparatus uses one roll.

  Along with the use of one separator roll 146, the present apparatus is configured such that the separator S is pulled out in advance by the length of the long side of the electrode member D, folded and wound. The tension chuck 147 can be lifted according to winding while pinching the leading end of the pulled-out separator S and applying tension to the separator S by its own weight to prevent winding disturbance. Note that a separate tension roller 148 is provided on the separator roll 146 to apply a tension against the supply of the separator S. Thereby, separator S will be in the state pulled by predetermined tension from both ends, and is preventing winding disorder. The separator S is stretched over the separator hook 136, the tension roller 148, and other rollers, but is positioned by appropriately providing a flange.

  A series of operations of feeding and winding will be described. First, the electrode members D are respectively placed on the delivery pedestal 131, and the negative electrode delivery pedestal 131b moves along the rail 134 so as to sink under the positive electrode delivery pedestal 131a. At this time, the separator is automatically pulled out by the separator hook 136. Therefore, when viewed from the horizontal direction, the negative electrode member Db, the separator S, and the positive electrode member Da are stacked in this order from the top. Note that the separator S is drawn in advance for the length of the long side of the electrode member D, and is held below the winding core 141 with the tension chuck 147 interposed therebetween.

  Subsequently, the core 141 is advanced from the short direction into the tip of the bundle of stacked negative electrode member Db, separator S, and positive electrode member Da, and the bundle is sandwiched between the sandwich plate 141a and the sandwich plate 141b. Similarly, the clamp roller 142 is lowered to integrate the bundle of members. Note that the sandwiching plate 141a and the sandwiching plate 141b are slightly shifted in the longitudinal direction so as to sandwich the bundle. Next, the separator hook 136 is pulled out in the short direction, and tension is applied to the separator S by the weight of the tension chuck 147. As a result, the electrode member D is positioned on both sides of the core 141, and the separator S to which a predetermined tension is applied is positioned without bending on both sides. An apparatus that supplies two separators supplies an extra amount to prevent short-circuiting. However, in this apparatus, the separator S is folded as a single piece at the end of the positive electrode member Da. There is also an advantage that there is no loss.

  Subsequently, the core 141 is rotated to wind up the bundle. At this time, the dancer roller 144 is moved up and down and lowered when the winding speed is increased, and is increased when the winding speed is decreased, so that the member is fed out from the clamp roller 142 side at a constant speed (see FIG. 7). Further, the presser roller 145 is brought into contact with the outer side of the core 141 and similarly moved up and down. At this time, the separator S drawn to the lower part of the core 141 rises with the rotation of the core 141.

  When the winding is completed, a protective winding tape having an adhesive tape on one side is wound (see FIG. 8). This is for fixing the wound member around the outside so that the bundle is not unwound. At the time of winding, the protective winding tape roller 149 comes into contact with the outside of the winding core, and the winding core 141 further rotates one or more times. In FIG. 1, reference symbol TR denotes a protective winding tape supply roll that supplies the protective winding tape.

  When the protective winding is completed, the holding plates 141a and 141b are not displaced, the bundle that has been slightly opened up and down is released, and the core 141 is pulled out in the short direction. FIG. 10 is an explanatory diagram for explaining the movement of the sandwiching plate. Among these, FIG. 10A is an explanatory view showing a state of the sandwiching plate immediately after winding, and FIG. 10B is an explanation showing a state where the sandwiching plate is not displaced and slightly opened up and down. FIG. In this way, the winding core 141 can be easily pulled out by narrowing the width and opening up and down.

  Note that the tight release of the clamping plates 141a and 141b or the insertion / extraction rotation control of the winding core 141 can be appropriately controlled using a program. Similarly, the movement of the dancer roller 144 and the presser roller 145 synchronizes with the rotation of the winding core 141, but this moving mechanism may be based on mechanical control or electronically controlled.

  Next, the transfer unit 105 will be described (see FIG. 2). The transfer unit 105 includes four suction heads 151 that suck in vacuum, and sucks and opens the electrode member D. The suction head 151 can be moved up and down by the cylinder 152 and the uniaxial robot 153, and moved in the lateral direction (short direction in which the electrode member is placed) by the moving rail 154 and the cylinder 155. Note that the movement distances of the four cylinders 152 and the single-axis robot 153 are not necessarily the same, and the lowering distance is made longer for the legs with respect to the positive electrode delivery base 131a. The number of suction heads is counted as one corresponding to each of the strip-shaped electrode members D. Even if a plurality of heads are assigned to one electrode member D, they are counted as one set. Shall.

  In the operation of the transfer unit 105, the electrode members D are sucked one by one from the stocker 111, and at the same time, the electrode members D positioned on the positioning base 121 are sucked and moved along the moving rail 153. Subsequently, the electrode member D sucked from the stocker 111 is placed on the positioning base 121 and the electrode member D sucked from the positioning base 121 is placed on the sending base 131 and released. Subsequently, the position returns to the original position along the moving rail 154, the electrode member D is again adsorbed from the stocker 111 and the positioning base 121, and this reciprocating motion is repeated.

  As an application example of the present invention, in addition to manufacturing the flat Li-ion battery described above, a flat capacitor can also be manufactured.
