Description

  The present invention relates to a conductor processing apparatus, a conductor processing method, a storage battery, and a conductor processing inspection apparatus.

  Some electrical components have a lead wire extended and provided with a terminal for connecting to another electrical device at the tip. In particular, among electrical components, a storage battery such as a lithium ion battery includes a positive electrode conductor extended from the positive electrode and a negative electrode conductor extended from the negative electrode.

  By the way, a storage battery such as a lithium ion battery is connected to a positive electrode conductor or a negative electrode terminal connected to a terminal such as an ammeter or a voltmeter after aging in the manufacturing process or before shipment, and inspects the electrical characteristics of the storage battery. Sometimes. Usually, the terminals of the positive electrode conductor and the negative electrode conductor are covered with a protective tube made of an insulating material such as rubber, for example, in order to prevent short-circuiting due to contact with each other, except at the time of inspection of electrical characteristics. .

  For example, in Patent Document 1, a protective tube that insulates and protects a terminal connected to a lead wire (conductive wire) is covered with the terminal, and a tip protruding from the terminal is folded and fixed. An insulation protection method is described. According to Patent Document 1, the length of the protective tube is increased, the terminal portion is inserted and covered, and then the tip is bent, and the lead wire side is fixed with a tape or the like, thereby changing the position or removing the work. It is said that it is easy to prevent short circuit between terminals during assembly, inspection and transportation of the battery pack.

JP 2009-176777 A

  However, in the technique described in Patent Document 1, since the protective tube is fixed to the conducting wire side with a tape or the like, it is necessary to attach and detach the tape in order to remove the protective tube when inspecting electrical components. For this reason, it takes time to remove the protective tube at the time of inspection of the electrical component, and the productivity of the electrical component is reduced. Therefore, the subject remains in the point of improving the productivity of an electrical component, preventing the short circuit of conducting wire.

  Then, this invention makes it a subject to provide the conducting wire processing apparatus, the conducting wire processing method, a storage battery, and a storage battery inspection method which can improve the productivity of an electrical component, preventing a short circuit.

A blade portion that abuts against the insulation coating, and the blade portion includes a blade surface facing the tip side of the conductor in the first direction when the insulation coating is cut, and the blade surface is It is characterized in that it is inclined toward the tip side of the conducting wire with respect to a virtual plane orthogonal to the first direction.

  According to the present invention, the blade surface provided on the blade portion of the cutting blade is inclined toward the distal end side of the conducting wire with respect to the virtual plane orthogonal to the first direction, and therefore, between the proximal end and the distal end of the conducting wire. By simply cutting the insulating coating, the insulating coating positioned closer to the leading end of the conducting wire than the cutting blade can be moved to the leading end side of the conducting wire along the inclined surface of the blade surface. Thereby, since the core wire of the front end side of a conducting wire can be covered with insulation coating, it can prevent that a core wire is exposed from the front end side of a conducting wire. Moreover, since the core wire of the conducting wire is exposed to the outside by cutting the insulating coating between the base end and the distal end of the conducting wire, other parts come into contact with the core wire of the conducting wire by the insulating coating positioned on both sides of the exposed core wire. Can be prevented. Therefore, it can suppress that the core wire of a conducting wire contacts with other components and an electrical component short-circuits. In addition, inspection of electrical components can be performed quickly by simply bringing a measuring terminal of a meter such as a voltmeter or ammeter into contact with the core wire exposed between the proximal end and the distal end of the conducting wire.

The core wire of the negative electrode conductor is exposed to the outside.

  According to the present invention, since the core wire of the positive electrode lead wire and the core wire of the negative electrode lead wire are exposed at different positions in the first direction, the core wire of the positive electrode lead wire and the core wire of the negative electrode lead wire are exposed at the same position in the first direction; In comparison, the contact of the core wire of the positive electrode conductor and the core wire of the negative electrode conductor can be suppressed. Therefore, it can suppress that the positive electrode and negative electrode of a storage battery short-circuit.

  The insulating coating of the positive electrode conductor is cut so that an exposed length along the first direction of the core wire of the positive electrode conductor is shorter than a diameter of the core wire of the negative electrode conductor, and the first of the core wires of the negative electrode conductor is cut The insulating coating of the negative electrode conductor is cut so that the exposed length along the direction is shorter than the diameter of the core wire of the positive electrode conductor.

Since it is set to less than 0 °, when the insulating coating is cut, the cut portion of the insulating coating can be widened by the blade surface and the auxiliary blade surface. Therefore, the insulation coating can be reliably cut. Furthermore, since the cutting blade moves to the leading end side of the conducting wire after the insulation coating is cut, the auxiliary blade surface suppresses the movement of the insulating coating located on the proximal end side of the conducting wire from the cutting blade, and more than the cutting blade.

Further, the negative electrode core wire 23 of the negative electrode lead wire 21 is between the base end and the tip end in the first direction F, and the negative electrode insulation coating 25 is cut at a position different from the exposed position of the positive electrode core wire 13 of the positive electrode lead wire 11. Exposed to the outside. More specifically, the negative electrode core wire 23 is formed such that the negative electrode insulating coating 25 is cut from the one end surface 2a of the battery unit 2 at a distance D2 that is longer than the distance D1, so that the base end side coating portion 25a and the distal end are covered. The negative electrode core wire 23 is exposed to the outside from between the proximal end side covering portion 25a and the distal end side covering portion 25b.
Thus, since the positive electrode core wire 13 and the negative electrode core wire 23 are exposed at different positions in the first direction F, compared to the case where the positive electrode core wire 13 and the negative electrode core wire 23 are exposed at the same position in the first direction F, It can suppress that the positive electrode core wire 13 and the negative electrode core wire 23 contact. Therefore, it is possible to prevent the positive electrode and the negative electrode of the storage battery 1 from being short-circuited via the positive electrode core wire 13 and the negative electrode core wire 23.
Note that the cutting of the positive electrode insulating coating 15 and the negative electrode insulating coating 25 is realized by a conductive wire processing device or a conductive wire processing inspection device described later.

FIG. 2 is an enlarged view of exposed portions of the positive electrode core wire 13 and the negative electrode core wire 23.
Here, as shown in FIG. 2, the diameter of the positive electrode lead wire 11 (corresponding to the diameter of the positive electrode insulation coating 15) is H1, the diameter of the positive electrode core wire 13 is K1, and the positive electrode core wire 13 is exposed along the first direction F. The length is L1, the diameter of the negative electrode conductor 21 (corresponding to the diameter of the negative electrode insulation coating 25) is H2, the diameter of the negative electrode core 23 is K2, and the exposed length of the negative electrode core 23 along the first direction F is L2. When the positive electrode core wire 13 and the negative electrode core wire 23 are
H2>K2> L1 (1)
And H1>K1> L2 (2)
It is formed to satisfy. That is, as shown in the formula (1), the exposed length L1 along the first direction F of the positive electrode core wire 13 is shorter than the diameter K2 of the negative electrode core wire 23, and as shown in the formula (2), the negative electrode The exposed length L2 along the first direction F of the core wire 23 is shorter than the diameter K1 of the positive electrode core wire 13.
By satisfying the formulas (1) and (2), the negative electrode core wire 23 can be prevented from entering between the proximal end side covering portion 15a and the distal end side covering portion 15b in the cut positive electrode insulating coating 15. The positive electrode core wire can be prevented from entering between the proximal end side covering portion 25a and the distal end side covering portion 25b in the cut negative electrode insulating coating 25. Therefore, it is possible to reliably prevent the positive electrode and the negative electrode of the storage battery 1 from being short-circuited via the positive electrode core wire 13 and the negative electrode core wire 23. In the present embodiment, the exposed length of the positive electrode core wire 13 is equal to L1 and the exposed length L2 of the negative electrode core wire 23, and the diameter K1 of the positive electrode core wire 13 and the diameter K2 of the negative electrode core wire 23 are equal. The diameter H1 of the positive electrode lead 11 and the diameter H2 of the negative electrode lead 21 are equal.

(First embodiment, conducting wire processing apparatus)
Then, the lead wire processing apparatus 30 of the positive electrode lead 11 and the negative electrode lead 21 which concern on 1st embodiment about the storage battery 1 mentioned above is demonstrated.
FIG. 3 is a schematic configuration diagram of the conducting wire processing apparatus 30 according to the first embodiment, and illustrates a state where the conducting wire 3 (the positive electrode conducting wire 11 in FIG. 3) is set. Here, the first direction in FIG. 3 coincides with the horizontal direction, the left side is the proximal end side of the conducting wire 3 in the first direction F, and the right side in FIG. On the side. Further, the vertical direction in FIG. 3 coincides with the vertical vertical direction. In addition, since the state which set the negative electrode conducting wire 21 (refer FIG. 2) is the same as the state which set the positive electrode conducting wire 11, illustration is abbreviate | omitted in FIG.

As shown in FIG. 3, the lead wire processing apparatus 30 includes a set jig 31 for setting the positive electrode lead wire 11 and the negative electrode lead wire 21 (see FIG. 1), and positive electrode insulation of the positive electrode lead wire 11 set on the set jig 31. A cutting blade 32 for cutting the coating 15 and the negative electrode insulating coating 25 (see FIG. 1) of the negative electrode conductor 21.
The setting jig 31 has a mounting surface 31a facing vertically upward. The mounting surface 31a is provided with a regulating member (not shown) for extending the conducting wire 3 in a straight line, for example. Thereby, the positive electrode conducting wire 11 and the negative electrode conducting wire 21 are arranged in parallel in a state of being linearly extended along the first direction F (see FIG. 1).

The cutting blade 32 that cuts the positive electrode insulation coating 15 of the positive electrode conducting wire 11 is formed of a metal material such as iron, copper, aluminum, or stainless steel, for example, and is, for example, an actuator (not shown) on one side end surface 2a ( It can move along the vertical vertical direction at a distance D1 from (see FIG. 1). The cutting blade 32 includes a blade portion 33 that contacts the positive electrode insulating coating 15 so as to intersect the first direction F when the positive electrode insulating coating 15 is cut.
The blade portion 33 includes a blade surface 34 that faces the distal end side (right side in FIG. 3) of the positive electrode conducting wire 11 in the first direction F when the positive electrode insulating coating 15 is cut. When the virtual surface orthogonal to the first direction F is defined as S, the blade surface 34 is inclined with respect to the virtual surface S by the angle θ1 toward the distal end side of the positive electrode conducting wire 11. The inclination angle θ1 of the blade surface 34 with respect to the virtual surface S is set to about 20 °, for example.
The inclination of the blade surface 34 is preferably 70% to 100% of the thickness of the cutting blade 32. For example, when the inclination is 70% with respect to the thickness of the cutting blade 32, 30% of the thickness of the cutting blade 32 is in contact with the positive electrode conductor 11 (conductor 3). Moreover, when the inclination is 100% with respect to the thickness of the cutting blade 32, the cutting blade 32 and the positive electrode conducting wire 11 (conducting wire 3) are in contact with each other as a continuous line in the vertical vertical direction. Further, the inclination of the blade surface 34 is more preferably 85 to 100% of the thickness of the cutting blade 32.
Moreover, inclination-angle (theta) 1 is 1-60 degrees, More preferably, it is 20-30 degrees.

4 is a view taken in the direction of arrow B in FIG.
As shown in FIG. 4, an arcuate portion 34 a is formed on the blade surface 34. The arc-shaped portion 34a is formed by a region corresponding to the positive electrode conducting wire 11 in the blade edge 33a of the blade portion 33 being recessed in a semicircular arc shape toward the blade base 33b side. The radius of the arc-shaped portion 34 a is equal to or greater than the radius of the positive electrode core wire 13 and is smaller than the radius of the positive electrode insulating coating 15. Thereby, since the blade part 33 can bite into the positive electrode insulation coating 15 after the arc-shaped part 34a contact | abuts to the positive electrode conducting wire 11, the positive electrode insulation coating 15 can be cut | disconnected from the perpendicular upper direction.

  The cutting blade for cutting the negative electrode insulation coating 25 (see FIG. 1) is capable of cutting the negative electrode insulation coating 25 at a distance D2 (see FIG. 1) from the one end surface 2a (see FIG. 1) of the battery unit 2. Except for the arrangement, the cutting blade 32 is the same as the cutting blade 32 for cutting the positive electrode insulation coating 15 described above. Therefore, a detailed description of the cutting blade for cutting the negative electrode insulation coating 25 is omitted.

Then, the conducting wire processing method which processes the conducting wire 3 (refer FIG. 1) of the storage battery 1 using the conducting wire processing apparatus 30 comprised as mentioned above is demonstrated. In addition, please refer to FIGS. 1-4 for each code | symbol in description of the following conducting wire processing methods.
FIG. 5 is a flowchart of each step in the wire processing method.
As shown in FIG. 5, the lead wire processing method includes a lead wire setting step S <b> 11 for setting the lead wire 3 of the storage battery 1 on the setting jig 31, a positive electrode insulation coating cutting step S <b> 13 for cutting the positive electrode insulation coating 15, and a negative electrode insulation coating 25. Negative electrode insulation coating cutting step S15.
In the conductive wire processing method, first, a conductive wire setting step S11 is performed. In the lead wire setting step S11, the positive electrode lead wire 11 and the negative electrode lead wire 21 are linearly extended and arranged side by side so as to be parallel to each other and placed on the placement surface 31a of the setting jig 31.

FIG. 6 is an explanatory diagram of the positive electrode insulation coating cutting step S13.
Subsequently, as shown in FIG. 6, in the positive electrode insulation coating cutting step S <b> 13, the cutting blade 32 is moved vertically downward at a distance D <b> 1 from the one end surface 2 a (see FIG. 1) of the battery unit 2 to positive electrode insulation. The coating 15 is cut to expose the positive electrode core wire 13 to the outside. At this time, the positive electrode core wire 13 is exposed to the outside so that the expression (1) is satisfied, that is, the exposed length L1 along the first direction F of the positive electrode core wire 13 is shorter than the diameter K2 of the negative electrode core wire 23. (See FIG. 2).
Here, the blade surface 34 of the cutting blade 32 is inclined toward the distal end side of the positive electrode conducting wire 11 with respect to the virtual surface S orthogonal to the first direction F. Therefore, when the positive electrode insulation coating 15 is cut between the proximal end and the distal end of the positive electrode conducting wire 11, the distal end side covering portion 15 b positioned closer to the distal end side of the positive electrode conducting wire 11 than the cutting blade 32 is formed on the inclined surface of the blade surface 34. It moves to the front end side of the positive electrode conducting wire 11 so as to follow. Thereby, since the front end surface of the front end side covering portion 15 b is disposed outside the front end surface 13 a of the positive electrode core wire 13, the positive electrode core wire 13 is not exposed from the front end of the positive electrode conducting wire 11.

Subsequently, in the negative electrode insulation coating cutting step S15, the cutting blade 32 is moved vertically downward at the position of the distance D2 from the one side end surface 2a of the battery unit 2 to cut the negative electrode insulation coating 25, and the negative electrode core wire 23 is set to the outside. Expose. At this time, the negative electrode core wire 23 is exposed to the outside so that the expression (2) is satisfied, that is, the exposed length L2 along the first direction F of the negative electrode core wire 23 is shorter than the diameter K1 of the positive electrode core wire 13 ( (See FIG. 2). Since the negative electrode insulation coating cutting step S15 is the same as the positive electrode insulation coating cutting step S13 except for the cutting position of the negative electrode insulation coating 25, the description thereof is omitted.
In this embodiment, the negative electrode insulation coating cutting step S15 is performed after the positive electrode insulation coating cutting step S13. However, the positive electrode insulation coating cutting step S13 and the negative electrode insulation coating cutting step S15 may be performed simultaneously, You may perform positive electrode insulation coating cutting process S13 after negative electrode insulation coating cutting process S15.

(effect)
According to the first embodiment, the blade surface 34 provided on the blade portion 33 of the cutting blade 32 is inclined toward the distal end side of the positive electrode conductor 11 with respect to the virtual surface S orthogonal to the first direction F. By simply cutting the positive electrode insulation coating 15 between the base end and the distal end of the positive electrode lead wire 11, the tip side covering portion 15 b positioned on the tip end side of the positive electrode lead wire 11 with respect to the cutting blade 32 is formed on the inclined surface of the blade surface 34. It can be made to move to the front end side of the positive electrode lead wire 11 along. Thereby, since the positive electrode core wire 13 can be covered with the positive electrode insulation coating 15 on the front end side of the positive electrode lead wire 11, it is possible to prevent the positive electrode core wire 13 from being exposed from the front end side of the positive electrode lead wire 11. Moreover, since the positive electrode core wire 13 is exposed to the outside by cutting the positive electrode insulation coating 15 between the base end and the tip of the positive electrode lead wire 11, the base end side covering portions 15a located on both sides of the exposed positive electrode core wire 13 and It is possible to prevent other components from coming into contact with the positive electrode core wire 13 by the front end side covering portion 15b. Therefore, it can suppress that the positive electrode core wire 13 contacts other components, and the storage battery 1 is short-circuited. Moreover, the test | inspection of the storage battery 1 can be quickly performed only by contact | abutting the measurement terminal of meters, such as a voltmeter and an ammeter, to the positive electrode core wire 13 exposed between the base end and front-end | tip of the positive electrode conducting wire 11. FIG. Therefore, productivity of the storage battery 1 can be improved while preventing a short circuit of the storage battery 1.
In addition, while conducting the conductor processing apparatus 30 which concerns on 1st embodiment similarly to the process of the negative electrode conducting wire 21, it can have the same effect.

  Further, since the positive electrode core wire 13 of the positive electrode conductor 11 and the negative electrode core wire 23 of the negative electrode conductor 21 are exposed at different positions in the first direction F, the positive electrode core wire 13 of the positive electrode conductor 11 and the negative electrode core wire 23 of the negative electrode conductor 21 are the first. Compared with the case where it is exposed at the same position in the direction F, it is possible to suppress contact between the positive electrode core wire 13 of the positive electrode conductor 11 and the negative electrode core wire 23 of the negative electrode conductor 21. Therefore, it is possible to suppress a short circuit between the positive electrode and the negative electrode of the storage battery 1.

  Further, the positive electrode insulation coating 15 is cut so that the exposed length L1 of the positive electrode core wire 13 is shorter than the diameter K2 of the negative electrode core wire 23, and the exposed length L2 of the negative electrode core wire 23 becomes shorter than the diameter K1 of the positive electrode core wire 13. Since the negative electrode insulation coating 25 is cut as described above, the negative electrode core wire 23 can be prevented from entering between the base end side coating portion 15a and the distal end side coating portion 15b in the cut positive electrode insulation coating 15 and the positive electrode core wire 13 can be prevented. Can be prevented from entering between the base end side covering portion 25a and the tip end side covering portion 25b in the cut negative electrode insulating coating 25. Therefore, since it can prevent that the positive electrode core wire 13 and the negative electrode core wire 23 contact, it can prevent that the positive electrode and negative electrode of the storage battery 1 short-circuit.

(Modification of the first embodiment)
FIG. 7 is a schematic configuration diagram of a conducting wire processing apparatus 30 according to a modification of the first embodiment.
Then, the conducting wire processing apparatus 30 which concerns on the modification of 1st embodiment is demonstrated.
In the wire processing device 30 of the first embodiment, the blade portion 33 of the cutting blade 32 includes a blade surface 34 that is inclined with respect to the virtual surface S by an angle θ1 on the distal end side of the positive electrode conductive wire 11 (see FIG. 3). .
On the other hand, as shown in FIG. 7, in the wire processing apparatus 30 according to the modification of the first embodiment, the blade portion 33 of the cutting blade 32 has an angle θ <b> 1 toward the front end side of the wire 3 with respect to the virtual plane S. It differs from 1st embodiment by the point provided with the blade surface 34 which only inclined and the taper surface 36 formed in the blade base 33b side above the blade surface 34. FIG. In addition, below, description is abbreviate | omitted about the component similar to 1st embodiment, and only a different part is demonstrated.

  The tapered surface 36 formed on the blade portion 33 is provided so as to be inclined with respect to the virtual surface S by an angle θ2 on the distal end side of the conducting wire 3 (the positive conducting wire 11 is shown in FIG. 7). The inclination angle θ2 of the tapered surface 36 with respect to the virtual surface S is larger than the inclination angle θ1 of the blade surface 34 with respect to the virtual surface S. The inclination angle θ1 of the blade surface 34 with respect to the virtual surface S is 20 °, while the inclination angle θ2 of the tapered surface 36 with respect to the virtual surface S is set to 30 °, for example.

  According to the modification of the embodiment, the taper surface 36 that is inclined toward the distal end side of the positive electrode conducting wire 11 is provided on the blade base 33b side with respect to the blade surface 34, and the inclination angle θ2 of the taper surface 36 is greater than the inclination angle θ1 of the blade surface 34. Therefore, after cutting the positive electrode insulation coating 15, the tip side covering portion 15 b positioned on the tip side of the positive electrode conducting wire 11 with respect to the cutting blade 32 is tapered with an inclination angle θ 2 larger than the inclination angle θ 1 of the blade surface 34. Along the surface 36, the positive electrode conductor 11 can be largely moved toward the tip side. Thereby, since the positive electrode core wire 13 on the front end side of the positive electrode lead wire 11 can be reliably covered with the positive electrode insulation coating 15, it is possible to reliably prevent the front end surface 13a of the positive electrode core wire 13 from being exposed from the front end side of the positive electrode lead wire 11. . In addition, the conducting wire processing apparatus 30 according to the modification of the first embodiment can be similarly applied to the processing of the negative electrode conducting wire 21 and can exhibit the same operational effects.

(Second embodiment)
FIG. 8 is a schematic configuration diagram of the wire processing apparatus 30 according to the second embodiment.
Then, the lead wire processing apparatus 30 which concerns on 2nd embodiment is demonstrated.
The conducting wire processing apparatus 30 of the first embodiment includes a cutting blade 32 that cuts the positive insulating coating 15 of the positive conducting wire 11 and exposes the positive electrode core wire 13 to the outside between the base end and the distal end of the positive conducting wire 11. (See FIG. 3).
On the other hand, as shown in FIG. 8, the conducting wire processing apparatus 30 according to the second embodiment is arranged on the proximal end side of the conducting wire 3 (the positive conducting wire 11 is shown in FIG. 8) in the first direction F of the cutting blade 32. The second embodiment is different from the first embodiment in that an auxiliary cutting blade 42 interlocked with the cutting blade 32 is provided. In addition, below, description is abbreviate | omitted about the component similar to 1st embodiment, and only a different part is demonstrated.

  As shown in FIG. 8, the auxiliary cutting blade 42 is disposed so as to be in close contact with the cutting blade 32 on the proximal end side (left side in FIG. 8) of the positive electrode conducting wire 11 in the first direction F of the cutting blade 32. Yes. As with the cutting blade 32, the auxiliary cutting blade 42 is formed of a metal material such as iron, copper, aluminum, or stainless steel, for example, along the vertical vertical direction in conjunction with the cutting blade 32 by an actuator (not shown). Can be moved.

The auxiliary cutting blade 42 includes an auxiliary blade portion 43. The blade edge 43 a of the auxiliary blade portion 43 is disposed so as to be positioned vertically above the blade edge 33 a of the blade portion 33. Therefore, the auxiliary blade portion 43 contacts the positive electrode insulating coating 15 so as to intersect the first direction F after the cutting blade 32 contacts the positive electrode insulating coating 15.
The auxiliary blade portion 43 includes an auxiliary blade surface 44 that faces the proximal end side of the positive electrode conductor 11 in the first direction F when the positive insulating coating 15 is cut by the cutting blade 32. The auxiliary blade surface 44 is inclined with respect to the virtual surface S by an angle θ3 toward the base end side of the positive electrode conductor 11. The inclination angle θ3 of the auxiliary blade surface 44 with respect to the virtual surface S is set to be larger than the inclination angle θ1 of the blade surface 34 with respect to the virtual surface S and smaller than 90 °. The inclination angle θ3 of the auxiliary blade surface 44 with respect to the virtual surface S in the present embodiment is set to about 60 °, for example.

Specifically, the cutting blade 32 and the auxiliary cutting blade 42 operate as follows.
At the time of cutting the positive electrode insulation coating 15, first, the cutting blade 32 and the auxiliary cutting blade 42 are simultaneously moved downward simultaneously. Subsequently, the cutting blade 32 comes into contact with the positive electrode insulation coating 15 first. Subsequently, the auxiliary cutting blade 42 comes into contact with the positive electrode insulating coating 15 while the cutting blade 32 is cutting the positive electrode insulating coating 15. As a result, the base end side covering portion 15a of the positive electrode insulation coating 15 located on the base end side with respect to the cutting blade 32 moves in the first direction F in a state where the base end side covering portion 15a is in contact with the auxiliary blade surface 44 of the auxiliary cutting blade 42. Be regulated. Subsequently, the cutting blade 32 moves downward and moves to the tip side of the positive electrode lead wire 11. Thereby, the cutting blade 32 can move the front end side covering portion 15 b of the positive electrode insulating coating 15 located on the front end side of the cutting blade 32 to the front end side of the positive electrode conducting wire 11 while cutting the positive electrode insulating coating 15. .

  Note that the cutting blade and the auxiliary cutting blade for cutting the negative electrode insulation coating 25 (see FIG. 1) are each at a position of a distance D2 (see FIG. 1) from the one end face 2a (see FIG. 1) of the battery unit 2. Except for being arranged so that 25 can be cut, it is the same as the cutting blade 32 and the auxiliary cutting blade 42 for cutting the positive electrode insulation coating 15 described above. Therefore, detailed description of the cutting blade and the auxiliary cutting blade for cutting the negative electrode insulating coating 25 is omitted.

  According to the second embodiment, the auxiliary blade surface 44 is inclined toward the proximal end side of the positive electrode conducting wire 11 with respect to the virtual surface S, and the inclination angle θ3 of the auxiliary blade surface 44 with respect to the virtual surface S is that of the blade surface 34. Since the inclination angle θ1 with respect to the virtual surface S is set to be larger than 90 ° and less than 90 °, the cutting portion of the positive electrode insulation coating 15 is widened by the blade surface 34 and the auxiliary blade surface 44 when the positive electrode insulation coating 15 is cut. be able to. Therefore, the positive electrode insulation coating 15 can be reliably cut. Further, since the cutting blade 32 moves to the tip end side of the positive electrode conducting wire 11 when cutting the positive electrode insulation coating 15, the tip side covering portion 15 b of the positive electrode conducting wire 11 can be moved to the tip end side of the positive electrode conducting wire 11. As a result, the positive electrode core wire 13 can be reliably covered with the positive electrode insulation coating 15, so that the positive electrode core wire 13 can be reliably prevented from being exposed from the tip end side of the positive electrode conducting wire 11.

(First modification of the second embodiment)
FIG. 9 is a schematic configuration diagram of a conducting wire processing apparatus 30 according to a first modification of the second embodiment.
Then, the conducting wire processing apparatus 30 which concerns on the 1st modification of 2nd embodiment is demonstrated.
The wire processing apparatus 30 according to the second embodiment includes an auxiliary cutting blade 42 that interlocks with the cutting blade 32 on the base end side of the positive electrode conducting wire 11 in the first direction F of the cutting blade 32, and the cutting blade 32 is positive electrode insulated. When the coating 15 was cut, it moved to the tip side of the positive electrode lead 11 (see FIG. 8).
On the other hand, as shown in FIG. 9, the wire machining apparatus 30 according to the first modification of the second embodiment has a cutting blade 32 on the proximal end side of the positive electrode conducting wire 11 in the first direction F of the cutting blade 32. And the cutting blade 32 is different from the second embodiment in that the cutting blade 32 moves to the tip side of the positive electrode conductor 11 after the positive electrode insulation coating 15 is cut. In addition, below, description is abbreviate | omitted about the component similar to 2nd embodiment, and only a different part is demonstrated.

Specifically, the cutting blade 32 and the auxiliary cutting blade 42 operate as follows.
When cutting the positive electrode insulation coating 15, first, the cutting blade 32 moves downward. Subsequently, the auxiliary cutting blade 42 moves downward so as to follow the cutting blade 32 after the cutting blade 32 cuts the positive electrode insulation coating 15. As a result, the base end side covering portion 15a of the positive electrode insulation coating 15 located on the base end side with respect to the cutting blade 32 moves in the first direction F in a state where the base end side covering portion 15a is in contact with the auxiliary blade surface 44 of the auxiliary cutting blade 42. Be regulated. Subsequently, the cutting blade 32 slides in the horizontal direction along the first direction F toward the distal end side of the positive electrode conducting wire 11. Thereby, the cutting blade 32 can move the front end side covering portion 15 b of the positive electrode insulating coating 15 located on the front end side of the cutting blade 32 to the front end side of the positive electrode conducting wire 11 after cutting the positive electrode insulating coating 15. .

  According to the first modified example of the second embodiment, the auxiliary blade surface 44 is inclined to the proximal end side of the positive electrode conducting wire 11 with respect to the virtual surface S, and the inclination angle θ3 of the auxiliary blade surface 44 with respect to the virtual surface S. Is set to be larger than the inclination angle θ1 of the blade surface 34 with respect to the virtual surface S and less than 90 °, so that when the positive electrode insulation coating 15 is cut, the cutting position of the positive electrode insulation coating 15 is defined as the blade surface 34 and the auxiliary blade. The surface 44 can be expanded. Therefore, the positive electrode insulation coating 15 can be reliably cut. Furthermore, since the cutting blade 32 moves to the distal end side of the positive electrode conducting wire 11 after cutting the positive electrode insulating coating 15, the distal blade side covering portion 15b is moved while the movement of the proximal end side covering portion 15a is suppressed by the auxiliary blade surface 44. The positive electrode conductor 11 can be moved to the tip side. As a result, the positive electrode core wire 13 can be reliably covered with the positive electrode insulation coating 15, so that the positive electrode core wire 13 can be reliably prevented from being exposed from the tip end side of the positive electrode conducting wire 11.

(Second modification of the second embodiment)
FIG. 10 is a schematic configuration diagram of a conducting wire machining apparatus 30 according to a second modification of the second embodiment.
Then, the conducting wire processing apparatus 30 which concerns on the 2nd modification of 2nd embodiment is demonstrated.
The wire processing apparatus 30 according to the second embodiment includes an auxiliary cutting blade 42 that interlocks with the cutting blade 32 on the base end side of the positive electrode conducting wire 11 in the first direction F of the cutting blade 32, and the cutting blade 32 is positive electrode insulated. When the coating 15 was cut, it moved to the tip side of the positive electrode lead 11 (see FIG. 8).
On the other hand, as shown in FIG. 10, the wire machining apparatus 30 according to the second modified example of the second embodiment includes a cutting blade 32 and an auxiliary cutting blade 42 that interlocks with the cutting blade 32, and an auxiliary blade. This is different from the second embodiment in that a pressing jig 52 is provided on the proximal end side of the positive electrode conducting wire 11 with respect to the portion 43. In addition, below, description is abbreviate | omitted about the component similar to 2nd embodiment, and only a different part is demonstrated.

  The pressing jig 52 is a member formed in a prismatic shape from a metal material such as iron, copper, aluminum, stainless steel, or a resin material. The pressing jig 52 moves downward when the positive electrode insulation coating 15 is cut, presses the positive electrode insulation coating 15, and restricts the movement of the positive electrode insulation coating 15 on the proximal end side of the positive electrode conductor 11 from the auxiliary blade portion 43. Yes. The end surface 53 of the pressing jig 52 is subjected to, for example, graining or sandblasting, and is provided with fine irregularities. Thereby, when the positive electrode insulation coating 15 is pressed by the pressing jig 52, the friction coefficient between the end surface 53 of the pressing jig 52 and the positive electrode insulation coating 15 can be increased. It can be regulated reliably.

The pressing jig 52 presses the positive electrode insulation coating 15 before the cutting blade 32 moves to the front end side of the positive electrode conducting wire 11. Specifically, the pressing jig 52, the cutting blade 32, and the auxiliary cutting blade 42 operate as follows.
At the time of cutting the positive electrode insulation coating 15, first, only the pressing jig 52 moves downward, and the end surface 53 of the pressing jig 52 contacts the positive electrode insulation coating 15. Thereby, the movement in the first direction F of the base end side covering portion 15a of the positive electrode insulating cover 15 positioned on the base end side with respect to the cutting blade 32 is restricted. Subsequently, the cutting blade 32 moves downward and moves to the tip side of the positive electrode lead wire 11. Thereby, the front end side covering portion 15 b of the positive electrode insulation coating 15 positioned on the front end side with respect to the cutting blade 32 can move to the front end side of the positive electrode conducting wire 11 with the movement of the cutting blade 32. The pressing jig 52 only needs to press the positive electrode insulation coating 15 before at least the cutting blade 32 moves to the tip side of the positive electrode conducting wire 11. Therefore, for example, the end face 53 of the pressing jig 52 may contact the positive electrode insulating coating 15 at the same time that the cutting blade 32 contacts the positive electrode insulating coating 15.

  The pressing jig that presses the negative electrode insulation coating 25 is disposed so that the negative electrode insulation coating 25 can be cut at a distance D2 (see FIG. 1) from the one end surface 2a of the battery unit 2 (see FIG. 1). The pressing jig 52 is the same as the pressing jig 52 that presses the positive electrode insulation coating 15 except that the cutting blade and the auxiliary cutting blade are disposed closer to the base end side in the first direction F. Therefore, detailed description of the pressing jig that presses the negative electrode insulation coating 25 is omitted.

  According to the second modification of the second embodiment, the pressing jig 52 that restricts the movement of the base end side covering portion 15a of the positive electrode conductor 11 is provided, and the pressing jig 52 has the cutting blade 32 having the positive electrode conductor. Since the positive electrode insulation coating 15 is pressed before moving to the distal end side of the electrode 11, the cutting edge 32 prevents the proximal end side coating portion 15a of the positive electrode insulation coating 15 from moving, and the distal end side coating portion of the positive electrode lead wire 11 by the cutting blade 32 15b can be moved to the tip side. Therefore, the positive electrode insulation coating 15 can be surely cut to expose the positive electrode core wire 13, and the positive electrode core wire 13 on the distal end side of the positive electrode conducting wire 11 can be reliably covered with the positive electrode insulation coating 15.

A pair of cutting units 61 are provided corresponding to the positive electrode conductor 11 and the negative electrode conductor 21. For example, the probe pin 65 is configured to move downward in conjunction with the downward movement of the cutting blade 32.
A voltmeter 83 (see FIG. 11) is electrically connected between one probe pin 65 disposed on the positive electrode lead 11 side and the other probe pin 65 disposed on the negative electrode lead 21 side. .

  When the cutting blade 32 cuts the positive electrode insulation coating 15, one probe pin 65 is inserted into the positive electrode insulation coating 15 on the proximal end side of the positive electrode conducting wire 11 with respect to the one cutting blade 32 and is attached to the positive electrode core wire 13.

Further, when the other cutting blade 32 cuts the negative electrode insulation coating 25, the other probe pin 65 is inserted into the negative electrode insulation coating 25 on the proximal end side of the negative electrode conductor 21 with respect to the other cutting blade 32. It contacts the negative electrode core wire 23. Thus, the voltmeter 83 (see FIG. 11) is connected to the negative electrode of the positive electrode core wire 13 and the negative electrode conductor 21 on the storage battery 1 side (see FIG. 11) from the AC power supply 81 and the ammeter 82 (see FIG. 11). Electrically connected in parallel to the core wire 23. That is, one probe pin 65 arranged on the positive electrode lead 11 side functions as the measurement terminal T2, and the other probe pin 65 arranged on the negative electrode lead wire 21 side functions as the measurement terminal T4.

  The order of the downward movement of the probe pin 65 and the cutting blade 32 is not limited, but the probe pin 65 moves downward before the cutting blade 32 and is inserted into the positive electrode insulating coating 15 and the negative electrode insulating coating 25. Is preferred. In this case, the probe pin 65 cuts while restricting the movement of the base end side covering portion 15a of the positive electrode insulating coating 15 and the base end side covering portion 25a of the negative electrode insulating coating 25 located on the base end side with respect to the cutting blade 32. The positive electrode insulating coating 15 and the negative electrode insulating coating 25 can be cut by the blade 32.

  According to the first modification of the third embodiment, the tip side covering portion 15 b of the positive electrode insulating coating 15 and the tip side covering portion 25 b of the negative electrode insulating coating 25 located on the tip side of the cutting blade 32 are arranged on the blade surface 34.

Therefore, the electrical characteristics of the storage battery 1 can be easily and accurately inspected by the so-called four-terminal method. Therefore, productivity of the storage battery 1 can be improved while suppressing a short circuit between the positive electrode and the negative electrode of the storage battery 1.

(Second modification of the third embodiment)
Then, the conducting wire processing inspection apparatus 60 which concerns on the 2nd modification of 3rd embodiment is demonstrated. In addition, below, description is abbreviate | omitted about the component similar to 3rd embodiment, and only a different part is demonstrated.
FIG. 14 is a schematic configuration diagram of a wire processing inspection apparatus 60 according to a second modification of the third embodiment. The reference numerals in parentheses in FIG. 14 correspond to the reference numerals in the case where the state immediately after the cutting blade 32 cuts the negative electrode insulating coating 25 of the negative electrode conductor 21 as in FIGS. 12 and 13.
FIG. 15 is a view taken in the direction of arrow C in FIG.
The conducting wire processing inspection apparatus 60 according to the first modification of the third embodiment includes a cutting blade 32 and a probe pin 65 (see FIG. 13).
On the other hand, as shown in FIG. 14, the conductor wire processing inspection apparatus 60 according to the second modification of the third embodiment includes the cutting blade 32 and the probe pin 65, and the positive electrode conductor 11 ( This is different from the first modification of the third embodiment in that a pressing jig 68 is provided on the base end side of the negative electrode conducting wire 21). In addition, below, description is abbreviate | omitted about the component similar to the 1st modification of 3rd embodiment, and only a different part is demonstrated.

  The pressing jig 68 is a member formed in a rectangular plate shape from a metal material such as iron, copper, aluminum, stainless steel, or a resin material. As shown in FIG. 15, the pressing jig 68 has a V-shaped pressing groove 69 that opens downward in the direction of arrow C at a position corresponding to the positive electrode conductor 11 (negative electrode conductor 21).

  The pressing jig 68 applies the positive insulating coating 15 before the probe pin 65 is inserted into the positive insulating coating 15 and the negative insulating coating 25 and before the cutting blade 32 comes into contact with the positive conducting wire 11 and the negative conducting wire 21. Press. As a result, the pressing jig 68 causes the positive electrode insulation coating 15 and the negative electrode insulation when the probe pin 65 is inserted into the positive electrode insulation coating 15 and the negative electrode insulation coating 25 and when the positive electrode insulation coating 15 and the negative electrode insulation coating 25 are cut. The coating 25 is pressed by the inner side surfaces 69 a and 69 a of the pressing groove 69 to restrict the movement of the positive electrode insulating coating 15 and the negative electrode insulating coating 25.

  The inner surface 69a of the pressing groove 69 is subjected to, for example, graining or sandblasting, and is provided with fine irregularities. Therefore, when the positive electrode insulating coating 15 and the negative electrode insulating coating 25 are pressed by the inner side surfaces 69 a and 69 a of the pressing groove portion 69, the gap between the inner side surfaces 69 a and 69 a of the pressing groove portion 69 and the positive electrode insulating coating 15 and the negative electrode insulating coating 25 is reduced. Since the friction coefficient can be increased, the movement of the positive electrode insulating coating 15 and the negative electrode insulating coating 25 can be reliably regulated.

  According to the second modification of the third embodiment, the pressing jig 68 prevents the base end side covering portion 15a of the positive electrode insulating coating 15 and the base end side covering portion 25a of the negative electrode insulating coating 25 from moving, The electrical characteristics of the storage battery 1 can be easily and accurately inspected by the so-called four-terminal method. Therefore, the productivity of the storage battery 1 can be improved while reliably suppressing a short circuit between the positive electrode and the negative electrode of the storage battery 1.

  Further, by disposing the positive electrode conductor 11 and the negative electrode conductor 21 in the pressing groove 69, the pressing jig 68, the positive electrode conductor 11 and the negative electrode conductor 21 can be brought into contact with each other over a wide area. Thereby, the electrical characteristics of the storage battery 1 can be easily and accurately inspected by the so-called four-terminal method while reliably restricting the movement of the positive electrode conductor 11 and the negative electrode conductor 21. Therefore, the productivity of the storage battery 1 can be improved while reliably suppressing a short circuit between the positive electrode and the negative electrode of the storage battery 1.

(4th embodiment, conducting wire processing apparatus)
Then, the cutting blade 32 of the conducting wire processing apparatus 30 which concerns on 4th embodiment is demonstrated.
FIG. 16 is a perspective view of the cutting blade 32 of the wire processing apparatus 30 according to the fourth embodiment. In FIG. 16, the fixing portion of the cutting blade 32 in the wire processing apparatus 30 is illustrated by a two-dot chain line.
The shape of the cutting blade 32 is not limited to the above-described embodiments, and various changes can be made. For example, as illustrated in FIG. 16, the cutting blade 32 of the wire processing apparatus 30 according to the fourth embodiment includes a V-groove 38 that is formed in a V-shape when viewed from the first direction F, and a cutting edge 33 a of the blade 33. Have.
Further, an escape portion 39 is formed at the end of the V groove portion 38 of the blade edge 33a. The escape portion 39 is formed in an arc shape when viewed from the first direction F. The radius of curvature of the escape portion 39 is set to a size corresponding to the positive electrode core wire 13 and the negative electrode core wire 23 (both see FIG. 1), and the radius of curvature of the escape portion 39 and the radius of the positive electrode core wire 13 and the negative electrode core wire 23 are Are approximately the same size.
The blade base 33b is formed with a fixing hole 33c penetrating the cutting blade 32 in the first direction F and a U-shaped groove 33d having a bottom on the blade tip 33a side. For example, a bolt (not shown) is inserted into the fixing hole 33 c and the cutting blade 32 is fastened to a fixing portion of the wire processing apparatus 30. Further, by providing the U-shaped groove 33d, the cutting blade 32 can be moved along the extending direction of the cutting blade 32 and can be aligned when being fixed to the fixing portion of the wire processing apparatus 30.

FIG. 17 and FIG. 18 are explanatory views of the wire processing apparatus 30 according to the fourth embodiment. FIG. 17 illustrates a state immediately before the conducting wire 3 (the positive conducting wire 11 in FIG. 17) is cut. FIG. 17 is a side cross-sectional view including the central axis of the positive electrode lead wire 11. FIG. 18 is a perspective view of the wire processing apparatus 30 according to the fourth embodiment.
As shown in FIG. 17, the conducting wire processing apparatus 30 includes an auxiliary cutting blade 42. The auxiliary cutting blade 42 has the same shape as the cutting blade 32. That is, the auxiliary cutting blade 42 has a V-groove portion 48 at the blade edge 43 a and a relief portion 49 at the other end of the V-groove portion 48. As a result, the positive electrode insulation coating 15 can be cut with the conductive wire 3 interposed therebetween. A detailed description of the auxiliary cutting blade 42 is omitted.

The cutting blade 32 is disposed such that the blade surface 34 is inclined with respect to the virtual surface S toward the tip end side (right side in FIG. 17) of the positive electrode conducting wire 11. Further, the auxiliary cutting blade 42 is disposed so that the auxiliary blade surface 44 is inclined with respect to the virtual surface S toward the proximal end side (left side in FIG. 17) of the positive electrode conducting wire 11.
When cutting the positive electrode insulation coating 15 of the positive electrode lead wire 11, the cutting edge 43 a of the auxiliary cutting blade 42 abuts on the positive electrode insulation coating 15, and then the cutting edge 33 a of the cutting blade 32 abuts on the positive electrode insulation coating 15. Then, as shown in FIG. 18, the positive electrode insulation coating 15 can be cut by moving the V groove portion 38 of the cutting blade 32 and the V groove portion 48 of the auxiliary cutting blade 42 so as to be close to each other.
According to 4th embodiment, since the blade part 33 is formed in V shape, the conducting wire 3 to be cut | disconnected can be guide | induced to the blade part 33, and can be cut | disconnected reliably. Further, an arc-shaped relief portion 39 is formed at the other portion of the blade portion 33 when viewed from the first direction F, and the radius of curvature of the relief portion 39 has a size corresponding to the core wire (the positive electrode core wire 13 in the embodiment). Since it is set, the blade portion 33 can reliably cut only the insulating coating (positive insulating coating 15 in the embodiment) and can prevent the positive electrode core wire 13 from being cut.

  The lead wire processing device 30 is formed so as to be rotatable around the positive electrode lead wire 11 after the cutting blade 32 and the auxiliary cutting blade 42 come into contact with the positive electrode insulation coating 15 when cutting the positive electrode insulation coating 15 of the positive electrode lead wire 11. (See the arrow in FIG. 18). Furthermore, it is preferable to apply an appropriate tension to the positive electrode lead wire 11 such as pulling back and forth. In this case, the insulating coating can be reliably cut over the entire circumference. Moreover, the cutting condition of the positive electrode insulation coating 15 can be adjusted as desired by adjusting the contact pressure of the cutting blade 32 and the auxiliary cutting blade 42 against the positive electrode insulation coating 15. Therefore, for example, the so-called half-cut state can be achieved without completely cutting the positive electrode insulation coating 15.

FIG. 19 is a front view of a cutting blade 32 according to a modification of the fourth embodiment.
As shown in FIG. 19, the cutting blade 32 according to the modification of the fourth embodiment is formed with a stepped portion 37 at the other end of the V-groove portion 38. The step portion 37 is formed in a U-shaped region in front view from the intermediate portion in the height direction of the V groove portion 38 to the top portion of the portion, and the thickness of the portion corresponding to the step portion 37 of the portion is different. It is thinner than the part. Due to the step portion 37, the thickness of the portion is thinner than the diameter of the core wires (the positive electrode core wire 13 and the negative electrode core wire 23, see FIG. 1). Thus, the exposed lengths L1 and L2 (see FIG. 2) of the positive electrode core wire 13 and the negative electrode core wire 23 after cutting the positive electrode insulating coating 15 and the negative electrode insulating coating 25 are the thicknesses of the portions corresponding to the step portions 37 of the portions. Is equivalent. That is, according to the modification of the fourth embodiment, the exposed lengths L1 and L2 of the positive electrode core wire 13 and the negative electrode core wire 23 after cutting of the positive electrode insulating coating 15 and the negative electrode insulating coating 25 are Since the diameter is shorter than the diameter, the positive electrode core wire 13 and the negative electrode core wire 23 can be prevented from entering each other. Therefore, the positive electrode core wire 13 and the negative electrode core wire 23 can be prevented from coming into contact with each other, so that the electrical component can be prevented from being short-circuited.

The cutting blade 32 is disposed so that the blade surface 34 is inclined to the tip side (right side in FIG. 17) of the positive electrode 11 with respect to the virtual plane S when the cutting edge 33 a comes into contact with the conductive wire 3 (positive electrode 11). ing. A connecting gear portion 35a is provided on the side surface of the first rotary blade unit 35A. The first rotary blade unit 35A and the second rotary blade unit 35B are meshed with each other via a connecting gear portion 35a and an intermediate gear (not shown), a belt, and the like, and can rotate in conjunction with each other. Thereby, the positive electrode insulation coating 15 can be cut while aligning while rotating the first rotary blade unit 35A and the second rotary blade unit 35B.

The first rotary blade unit 35A and the second rotary blade unit 35B cut the positive electrode insulation coating 15 by moving relative to each other so that the cutting blades 32 are close to each other with the positive electrode insulation coating 15 being sandwiched therebetween. Can do.
Here, the cutting blades 32 of the first rotary blade unit 35A and the second rotary blade unit 35B function as measurement terminals T1 and T2 (both see FIG. 11) of the ammeter 82 and the voltmeter 83, respectively. Similarly, in the negative electrode lead wire 21 (see FIG. 11), the cutting blades 32 of the first rotary blade unit 35A and the second rotary blade unit 35B are respectively connected to the measurement terminal of the voltmeter 83 and the measurement terminal T3 of the ammeter 82. It functions as T4 (both see FIG. 11). As described above, according to the fifth embodiment, the cutting blade 32 of the rotary blade unit 35 (35A, 35B) facilitates the electrical characteristics of electric components such as the storage battery 1 (see FIG. 11) by the so-called four-terminal method. Inspection can be performed accurately and at low cost. Therefore, it is possible to improve the productivity of the electrical component while suppressing a short circuit between the positive electrode and the negative electrode of the electrical component.

The current value or voltage value is measured. As described above, in the modified example of the fifth embodiment, it is possible to easily and inexpensively inspect the electrical characteristics of electrical components such as a storage battery by a so-called two-terminal method. Therefore, it is possible to improve the productivity of the electrical component while suppressing a short circuit between the positive electrode and the negative electrode of the electrical component.

With the cutting blade 32 having such a shape, the positive electrode core wire 13 (core wire) is crushed and the contact area between the cutting blade 32 and the positive electrode core wire 13 (core wire) is increased as shown in FIG. Moreover, the oxide film on the surface of the positive electrode core wire 13 (core wire) is broken, and the metal of the positive electrode core wire 13 (core wire) and the cutting blade 32 are easily brought into direct contact. For this reason, the electrical characteristics can be inspected more easily and accurately.

For example, the locking mechanism uses at least a claw-like convex portion, and a combination of the convex portion and the concave portion or a combination of the convex portion and the convex portion can be used. Furthermore, you may have the mechanism which cancels | releases the lock mechanism simultaneously.
Further, in the present invention, the positive electrode lead 11 and the negative electrode lead 21 such as the storage battery 1 are taken as an example, but the present invention can also be used for an electronic component having an insulation coating such as a thermistor.
