Description

  The present invention relates to a method and apparatus for transporting an electronic component lead wire, which is a precondition for tabbing an electrode foil in a manufacturing process of an electrolytic capacitor element, with the flat portions of the lead wire and the tab thereof being in the same horizontal state. In particular, the lead wire on which the tab is attached or formed and the flat plate portion of the tab are simultaneously changed from the upright state to the same horizontal state by the rotation of the drum, and can be reliably carried out to the next tab attaching step. The present invention relates to a lead wire conveying method and apparatus.

  In the manufacturing process of the electrolytic capacitor element, there is a step (tab attachment) of the lead wire having the flat plate portion formed on the tab, and the lead wire is conveyed by the feeder in an upright state. Therefore, it is necessary to make the flat portions of the lead wires and the tabs thereof be in the same horizontal state and to crimp the flat plates on the electrode foil.

  Conventionally, as shown in FIGS. 16 and 17, the lead wires 2 that have been conveyed by the feeder 1 are cut off one by one and dropped onto an R chute (not shown) as a means for horizontally setting the lead wires in an upright state. There is a chute type that slides on the R chute in the direction of arrow A and is received by a receiver 3 in which a V groove 3a is formed horizontally.

  However, the shape, length, width, etc. vary greatly depending on the type of the lead wire 2 and the balance of the weights also differs. With this method, how the R-chute slides after the lead wire 2 freely falls from the feeder. The position at which the stopper 3 stops is left to the end, and due to variations in the stopping position of the lead wire 2 on the receiver 3, the caulking position on the electrode foil is shifted or the tab 2a is scratched. As a result, the caulking becomes unstable, for example, the electrode foil is cut.

  In addition, the lead wire 2 may spring out of the V-groove 3a of the receiver 3, or the wear powder may gradually adhere to the R chute, causing slippage, and the lead wire 2 may stop halfway. It was.

  Furthermore, since the lead wire 2 is freely dropped, the lead wire 2 itself may be damaged or bent, and the lead wire 2 may be defective.

  In the conventional example, in the state where the lead wire 2 is received by the V groove 3a of the receiver 3, the flat plate portion 2b of the tab 2a is not in the same horizontal state as the lead wire 2, and this is the horizontal state. In order to do this, another mechanism was required.

  For example, as shown in FIGS. 18 and 19, the V-groove 5a of the slide member 5 is hung on the flat plate portion 2b on the pedestal 4 and slid in the direction of arrow B, whereby the lead wire 2 is rotated in the direction of arrow C, and the flat plate As shown in FIGS. 20 and 21, a flat plate portion 2b is brought into contact between slide members 6 and 8 that slide in opposite directions, as shown in FIGS. Thus, the lead wire 2 is horizontally arranged, the slide member 6 is slid in the direction of arrow B, the slide member 8 is slid in the direction of arrow D, the lead wire 2 is rotated in the direction of arrow C, and the flat plate portion 2b is connected to the lead wire 2 A mechanism to make the same horizontal state was provided.

  As means for bringing the upright lead wires into a horizontal state, there is a drum type as shown in FIGS. 22 and 23 other than the chute type. A plurality of grooves 9a are formed on the outer periphery to accommodate the lead wires 2, and a disk-shaped drum 9 in which magnets 9b are arranged inside the grooves 9a is intermittently rotated, for example, in the direction of arrow E. The lead wire 2 supplied to the hopper 10 from a feeder (not shown) is lifted one by one by moving the scraper 11 up and down in the directions of arrows F and G in synchronization with the intermittent rotation of the drum 9, and the magnetic force of the magnet 9b It is comprised so that it may make it adhere in the groove | channel 9a. In the hopper 10, for example, an appropriate amount of the lead wire 2 is supplied by opening and closing the valve 12 in the direction of arrow H or arrow I as appropriate.

  However, this drum type has a high cost due to the large number of parts, and since the lead wire 2 is attached to the drum 9 by the magnet 9b, the lead wire made of non-magnetic material that cannot be attracted to the magnet, such as soft copper wire, is used. It could not be used, and could only be used for lead wires such as nickel-plated iron wires and copper-clad steel wires (CP wires).

  The present invention relates to an electronic component lead wire conveying method in which electronic component lead wires conveyed one after another by a feeder are turned one by one in a horizontal state and conveyed to the next process, and the center is formed in a truncated cone shape. At the position where the conical surface of the drum that rotates intermittently with the shaft tilted faces the lead wire in the upright state, the lead wire is adsorbed to the conical surface one by one by suction of air, and the drum rotates at a predetermined angle. Since the lead wire is transported in a horizontal state, the lead wire is accurately gripped without being scratched or bent, and it is securely transported to the tab attaching process, which is the next process.

  Hereinafter, the present invention will be described based on embodiments shown in the drawings. The electronic component lead wire conveying device 15 according to the present invention includes a drum 16, a tab contact portion 18, and a handler 19 in FIGS. 1 to 3.

  The drum 16 is formed in a truncated cone shape having an apex angle of approximately 90 °, and is configured such that the central shaft 20 is intermittently rotated with a tilt of approximately 45 °, and the electronic component lead wire 22 conveyed in an upright state from the feeder 21. (Hereinafter simply referred to as “lead wire 22”) can be adsorbed one by one at the lowest point 16b of the conical surface 16a by suction of air, and lead at the highest point 16c rotated approximately 1/2 from the lowest point 16b. The line 22 is configured to be horizontal.

  A groove 16e is formed at the center in the width direction of the conical surface 16a so that the handler 19 can easily grasp the lead wire 22 at the uppermost point 16c. The portions on both sides of the groove 16e of the conical surface 16a are each formed in a bank shape over the entire circumference, and here are suctions for sucking the lead wires 22 arranged radially and evenly from the center of the drum. A portion 16f is formed.

  The adsorbing portion 16f is formed in a groove shape that is slightly wider than the lead wire 22 so that the lead wire 22 just fits, and this width is appropriate depending on the type and shape of the lead wire 22. Make it big.

  The lead wire 22 straddles the groove 16e and is sucked at two points by suction portions 16f formed in a bank shape on both sides of the groove 16e. An intake hole 16 g is formed, and all the intake holes 16 g communicate with the inside of the drum 16.

  The drum 16 is fixed to the central shaft 20 by screws 23 and is configured to rotate as the central shaft 20 rotates.

  On the lower surface side of the drum 16, for example, a manifold 24 made of synthetic resin is rotatably attached coaxially with the drum. A bevel gear 25 is further attached to the central shaft 20 via a key 26 and fixed by a screw 28.

  A compression spring 29 is attached between the bevel gear 25 and the manifold 24, and the manifold 24 is pressed against the drum 16 to be in close contact therewith. A thrust bearing 30 is attached between the compression spring 29 and the manifold 24.

  The manifold 24 is formed with a screw hole 24 a for attaching a hose joint (not shown). The screw hole 24 a communicates with the upper surface side of the manifold 24, that is, the side in contact with the drum 16. By being pressed, the screw hole 24 a communicates with the intake hole 16 g of the drum 16.

  Since the manifold 24 is rotated with the drum 16 as it is, a rotation-preventing plate 31 is attached to the lower surface side of the manifold 24 with screws 32, and the plate 31 is attached to the rotation-preventing pole 37. By engaging with, the companion is prevented.

  The central shaft 20 is pivotally supported on a base 34 via a bearing 33, and the base 34 is fixed to a control unit 35 with, for example, screws 36. The shafts 38 and 39 protrude from the control unit 35, and the driving force is transmitted to the shaft 39 inside the control unit 35 by rotating the pulley 40 attached to the shaft 38 by the belt 41. Is configured to rotate. A bevel gear 42 that meshes with the bevel gear 25 is attached to the shaft 39.

  As shown in FIGS. 1 to 3 and FIGS. 12 to 14, the tab contact portion 18 is in a non-rotatable state on the same axis of the drum 16 so that the tab 22 a of the lead wire 22 adsorbed to the drum 16 contacts. The flat plate portion 22b of the tab 22a is forcibly tilted by the frictional force accompanying the rotation of the drum 16, and the flat plate portion 22b is in the same horizontal state at the uppermost point 16c.

  The tab contact portion 18 has an end surface formed as a conical surface 18a having an apex angle similar to that of the conical surface 16a of the drum 16 and is formed in a disk shape having a boss portion 18b. And are relatively pivotably mounted. The bearing 43 is fixed by a bearing retainer 44. In addition, a disk 45 is attached to the tab contact portion 18 using a screw 46 so that the lead wire 22 does not jump out in the direction of the flat plate portion 22b.

  Since the tab contact portion 18 is rotated with the drum 16 as it is, the rotation plate 48 is attached to the disk 45, and the rotation of the tab contact portion 18 is achieved by the engagement of the plate 48 with the pole 37. It is preventing.

  The handler 19 is configured to take out the lead wire 22 that has reached the position of the uppermost point 16c in a horizontal state in synchronization with the intermittent rotation of the drum 16 and carry it out to the next process. And reciprocally swing.

  The handler 19 is configured to open and close the grip arm 49 with a cam (not shown) to grip the lead wire 22, carry it to a predetermined position, and then release it. The gripping force uses the spring force of the tension spring 50. ing. The lower end of the grip arm 49 is formed to a size that can enter the groove 16e of the drum 16.

  In addition, an edge cutting mechanism for cutting, for example, one lead wire 22 at the final end conveyed by the feeder 21 from the subsequent lead wire 22 on the control unit, which is the terminal end of the feeder 21. 51 is provided.

  The edge cutting mechanism 51 is configured so that wedges 52 and 53 formed in a wedge shape can be moved in a direction perpendicular to the conveying direction of the lead wire 22 on the feeder 21 by a linear guide 54, and the claws 52 and 53 are tension springs 55. Thus, the lead wire 22 is biased in the direction in which the edge is cut.

  The nail | claw 53 is comprised so that the cancellation | release of edge cutting and the edge cutting state may be switched, for example with the cam which is not illustrated.

  In the method of the present invention (Claim 1), the electronic component lead wires 22 that are conveyed one after another by the feeder 21 in the upright state are changed to a horizontal state one by one and conveyed to the next process. In the method, at the position where the conical surface 16a of the drum 16 which is formed in a truncated cone shape and intermittently rotates with the central axis 20 inclined is opposed to the lead wire 22 in the upright state, the lead wires 22 are aired one by one on the conical surface 16a. And the lead wire 22 is transported so that the lead wire 22 is in a horizontal state at a position where the drum 16 is rotated by a predetermined angle.

  Further, the method of the present invention (Claim 2) transports the electronic component lead wires 22 which are conveyed one after another by the feeder 21 in the upright state, one by one in the horizontal state and conveyed to the next process. In the method, the lead wire 22 is adsorbed by air suction one by one to the conical surface 16a of the drum 16 which is formed in a truncated cone shape and intermittently rotates with the central axis 20 inclined, and the drum 16 is rotated approximately 1/2. In this method, the lead wire 22 is in a horizontal state, and the flat plate portion 22b of the tab 22a of the lead wire 22 is tilted during the rotation so that the flat plate portion 22b is in the same horizontal state.

  Further, according to the method of the present invention (Claim 3), the electronic component lead wires 22 that are conveyed one after another by the feeder 21 in the upright state are changed to the horizontal state one by one and conveyed to the next process. In the method, the lead wires 22 are adsorbed to the conical surface 16a of the drum 16 which is formed in a truncated cone shape having an apex angle of approximately 90 ° and intermittently rotates while the central axis 20 is inclined at approximately 45 ° by sucking air one by one. The lead wire 22 is in a horizontal state at a position where the drum 16 is rotated approximately 1/2, and the flat plate portion 22b of the tab 22a of the lead wire 22 is tilted during the rotation so that the flat plate portion 22b is in the same horizontal state. The horizontal lead wire 22 is removed from the drum 16 and carried out to the next process.

  The present invention is configured as described above, and the operation thereof will be described below. As shown in FIGS. 5 to 9, the lead wire 22 has a tab 22 a from a large one to a small one, and the lead wire 22 has a long to short one. For the width and depth of 16f, the one suitable for the lead wire 22 to be transported is used.

  The electronic component lead wire transport device 15 according to the present invention adsorbs the lead wire 22 by sucking air, so that the material of the lead wire 22 is nickel-plated iron wire, copper-clad steel wire (CP wire), etc. It can also be used with an annealed copper wire.

  The lead wire 22 is conveyed on the feeder 21 toward the drum 16 in an upright state and in an aligned state. The edge cutting mechanism 51 reciprocates the claws 52 and 53 to edge-cut the lead wires 22 one by one and further advance them to approach the drum 16.

  When the shaft 38 of the control unit 35 is intermittently driven by the belt 41 at a predetermined timing, the shaft 39 is intermittently rotated by the control unit 35. As a result, the bevel gear 42 is also intermittently rotated, and the bevel gear 25 meshed with the bevel gear is also intermittently rotated.

  When the bevel gear 25 is intermittently rotated, the central shaft 20 and the drum 16 are also intermittently rotated in exactly the same manner as the bevel gear 25. However, the manifold 24 and the tab abutting portion 18 are not rotated and thus do not rotate. Only the drum 16 positioned between 24 and the tab contact portion 18 rotates intermittently in the direction of the arrow K, for example.

  When the drum 16 is temporarily stopped during intermittent rotation, as shown in FIG. 10, one lead wire 22 is fed out from the feeder 21 in the arrow L direction at the lowest point 16b, and is sucked by the suction portion 18f by air suction. .

  As shown in FIGS. 11 to 13, air is sucked in the direction of arrow O from a hose joint (not shown) attached to the screw hole 24 a of the manifold 24. Although the manifold 24 is always non-rotating, the screw hole 24a is always in communication with the suction hole 16g of the suction portion 16f, and the manifold 24 is pressed against the drum 16 by the spring force of the compression spring 29. There is no leakage, and even if the drum 16 rotates intermittently, air is always sucked stably in the direction of arrow P from each intake hole 16g.

  When the drum 16 rotates approximately ½ in the direction of arrow K, the lead wire 22 in the attracted state reaches the uppermost point 16c. Here, since the apex angle of the conical surface 16a of the drum 16 is 90 ° and the central axis 20 is inclined by about 45 °, the lead wire 22 that is in the upright state at the lowest point 16b is the highest point 16c. In the horizontal state.

  When the lead wire 22 is attracted to the attracting portion 16f, the flat plate portion 22b of the tab 22a is in contact with the conical surface 18a of the tab abutting portion 18. At this time, if the flat plate portion 22b is oriented in the tangential direction of the conical surface 18a, the flat plate portion 22b is directed in the tangential direction of the conical surface 18a while being conveyed from the lowest point 16b to the uppermost point 16c by the rotation of the drum 16. It is in contact with the conical surface 18a. When the highest point 16c is reached, the flat plate portion 22b is in the same horizontal state as the lead wire 22.

  On the other hand, when the lead wire 22 is attracted to the attracting portion 16f, if the flat plate portion 22b faces in a direction different from the tangential direction of the conical surface 18a of the tab abutting portion 18, the lowest point is caused by the rotation of the drum 16. While being conveyed from 16b to the uppermost point 16c, the lead wire 22 is forcibly rotated by the frictional force between the flat plate portion 22b and the conical surface 18a of the tab contact portion 18.

  More specifically, when the flat plate portion 22b faces in a direction different from the tangential direction of the conical surface 18a at the time of suction, as shown in FIG. 15, the lead wire 22 is incompletely sucked at the suction portion 16f. It is in a state. This is because the flat plate portion 22b stands with respect to the tab contact portion 18, and the lead wire 22 is adsorbed obliquely with respect to the direction of the conical surface 16a of the drum 16, and the groove 16e in the conical surface 16a. Of the two adsorbing portions 16f sandwiching the pin, on the tab 22a side, the air suction force is acting with the lead wire 22 slightly separated.

  In this case, the flat plate portion 22b acts on the lead wire 22 around the axial direction of the lead wire 22 due to the frictional force between the flat plate portion 22b and the tab contact portion 18 due to the rotation of the drum 16. Is rotated in the direction of arrow C, so that the flat plate portion 22b is tilted to the point where it faces the tangential direction of the conical surface 18a. When the flat plate portion 22b is tilted so far, the lead wire 22 is completely sucked in the suction portion 16f on the tab 22a side, and a moment is generated that the lead wire 22 rotates further and the flat plate portion 22b rises again. Instead, it is conveyed as it is to the uppermost point 16c.

  In this way, when the lead wire 22 is attracted to the drum 16, no matter which direction the flat plate portion 16b of the tab 16a faces, when the lead wire 22 is transported to the uppermost point 16c, it is in the same horizontal state as the lead wire 22. ing.

  As shown in FIGS. 1 and 10, the lead wire 22 is gripped by the handler 19 at the uppermost point 16c and removed from the drum 16 against the air suction force for the next caulking process. Then, it is carried out in the direction of arrow M. The handler 19 carries out the lead wires 22 one after another while intermittently reciprocatingly swinging by index feeding in synchronization with the intermittent rotation of the drum 16.
