The core wire 13 is a linear conductor, and here, the core wire 13 is formed by twisting a plurality of strands. The coating 14 is made of an insulating material such as resin. The coating 14 is formed, for example, by extrusion-coating a softened resin around the core wire 13.

In the present embodiment, the description will be made assuming that the direction in which the pair of core wire crimping pieces 24 b face each other is the width direction of the terminal 20. In addition, a description will be given assuming that the direction in which the pair of core wire crimping pieces 24 b is erected with respect to the bottom plate portion 24 a is the height direction of the terminal 20.
　先端側連結部２３は、芯線圧着部２４と相手側接続部２８とを繋ぐ部分である。先端側連結部２３は、底板部２３ａと、その底板部２３ａの両側に立設されて対向する一対の側壁部２３ｂとを備える。 The front end side connecting portion 23 is a portion connecting the core wire crimping portion 24 and the mating side connecting portion 28. The distal end side connecting portion 23 includes a bottom plate portion 23a and a pair of side wall portions 23b that are erected on both sides of the bottom plate portion 23a and face each other.
　電線接続部２２における各底板部２３ａ、２４ａ、２５ａ、２６ａは、全体として板状に連なる形状に形成されている。また、電線接続部２２における幅方向の一方の側の側壁部２３ｂ、芯線圧着片２４ｂ、側壁部２５ｂ、被覆圧着片２６ｂは、全体として板状に連なる形状に形成されている。同様に、電線接続部２２における幅方向の他方の側の側壁部２３ｂ、芯線圧着片２４ｂ、側壁部２５ｂ、被覆圧着片２６ｂも、全体として板状に連なる形状に形成されている。また、電線１２に対してかしめられる（曲げられる）部分である被覆圧着部２６の被覆圧着片２６ｂ及び芯線圧着部２４の芯線圧着片２４ｂは、中間連結部２５及び先端側連結部２３の各々の側壁部２５ｂ、２３ｂよりも高さ方向において長く形成されている。 Each bottom plate part 23a, 24a, 25a, 26a in the electric wire connection part 22 is formed in the shape which continues in plate shape as a whole. Moreover, the side wall part 23b, the core wire crimping piece 24b, the side wall part 25b, and the covering crimping piece 26b on one side in the width direction of the electric wire connection part 22 are formed in a shape that is continuous in a plate shape as a whole. Similarly, the side wall part 23b, the core wire crimping piece 24b, the side wall part 25b, and the covering crimping piece 26b on the other side in the width direction in the electric wire connection part 22 are also formed in a shape that is continuous in a plate shape as a whole. Further, the coated crimping piece 26b of the coated crimping portion 26 and the core crimping piece 24b of the core wire crimping portion 24 that are caulked (bent) portions with respect to the electric wire 12 are respectively connected to the intermediate coupling portion 25 and the distal end side coupling portion 23. It is formed longer in the height direction than the side walls 25b, 23b.
　また、相手側接続部２８は、相手側の電気的接続要素としての相手側導体Ｃと直接接触し、相手側導体Ｃに接続される部分（端子接続部）である。ここでは、相手側接続部２８は、相手側端子Ｃ１が嵌め入れられる孔である端子挿入孔２８ｈが形成された筒状の部分である。本実施形態では、相手側接続部２８は、角筒状に形成されており、内部に相手側端子Ｃ１と接触して弾性変形する接触片２９が設けられている。 Further, the counterpart connection portion 28 is a portion (terminal connection portion) that is in direct contact with the counterpart conductor C as the counterpart electrical connection element and connected to the counterpart conductor C. Here, the counterpart connection portion 28 is a cylindrical portion in which a terminal insertion hole 28h, which is a hole into which the counterpart terminal C1 is fitted, is formed. In the present embodiment, the mating connection portion 28 is formed in a rectangular tube shape, and a contact piece 29 that contacts the mating terminal C1 and elastically deforms is provided inside.
　ここでは、相手側接続部２８が筒形状の端子形状（いわゆるメス端子形状）に形成された例で説明するが、相手側接続部２８は、細長棒状又は細長板状の端子形状（いわゆるオス端子形状）を含む形状に形成されていてもよい。また、相手側接続部２８は、ボルト締め可能な形状、つまり平板状の本体部に貫通孔が形成された形状に形成されていてもよい。 Here, an example in which the mating side connection portion 28 is formed in a cylindrical terminal shape (so-called female terminal shape) will be described. However, the mating side connection portion 28 has an elongated rod-like or elongated plate-like terminal shape (so-called male terminal). (Shape) may be formed. Moreover, the other party connection part 28 may be formed in the shape which can be bolted, ie, the shape by which the through-hole was formed in the flat main body part.
　上記端子２０は次のようにして電線１２の端部に接続されている。すなわち、被覆１４の端部が被覆圧着部２６における一対の被覆圧着片２６ｂの間に位置し、露出芯線部１３ａが芯線圧着部２４における一対の芯線圧着片２４ｂの間に位置するように配置される。この状態で、被覆圧着部２６の被覆圧着片２６ｂは、底板部２６ａ上の被覆１４側（内側）へ曲げられる（かしめられる）。さらに、芯線圧着部２４の芯線圧着片２４ｂは、底板部２４ａ上の露出芯線部１３ａ側（内側）へ曲げられる（かしめられる）。これにより、被覆圧着部２６において、底板部２６ａと２つの被覆圧着片２６ｂとが被覆１４の端部に圧着された状態でこれを保持し、芯線圧着部２４において、底板部２４ａと２つの芯線圧着片２４ｂとが露出芯線部１３ａに圧着された状態でこれを保持する。この際、被覆１４の先端側縁部は、中間連結部２５の位置に位置し、一部が側壁部２５ｂの間から露出している。同様に、露出芯線部１３ａの先端側縁部は、先端側連結部２３の位置に位置し、一部が側壁部２３ｂの間から露出している。 The terminal 20 is connected to the end of the electric wire 12 as follows. That is, the end portion of the coating 14 is positioned between the pair of coated crimping pieces 26 b in the coated crimping portion 26, and the exposed core wire portion 13 a is positioned between the pair of core crimping pieces 24 b in the core wire crimping portion 24. The In this state, the coated crimping piece 26b of the coated crimping portion 26 is bent (caulked) toward the coating 14 (inside) on the bottom plate portion 26a. Furthermore, the core wire crimping piece 24b of the core wire crimping portion 24 is bent (caulked) to the exposed core wire portion 13a side (inner side) on the bottom plate portion 24a. Thereby, in the covering crimping portion 26, the bottom plate portion 26a and the two covering crimping pieces 26b are held in a state where they are crimped to the end portion of the covering 14, and in the core wire crimping portion 24, the bottom plate portion 24a and the two core wires are held. The crimping piece 24b is held in a state of being crimped to the exposed core part 13a. At this time, the front end side edge portion of the covering 14 is located at the position of the intermediate connecting portion 25, and a part thereof is exposed between the side wall portions 25 b. Similarly, the distal end side edge portion of the exposed core portion 13a is located at the position of the distal end side connecting portion 23, and a part thereof is exposed between the side wall portions 23b.
　ここで、電線１２の芯線１３（素線）と、端子２０とは、異種の金属によって構成されている。例えば、芯線１３は、アルミニウム又はアルミニウムを主成分とするアルミニウム合金によって構成されている。一方、端子２０は、銅若しくは銅を主成分とする銅合金（黄銅等）によって構成された部材、あるいはそれらの部材に錫（Ｓｎ）メッキ若しくは錫に銀（Ａｇ）、銅（Ｃｕ）、ビスマス（Ｂｉ）などが添加された錫合金のメッキが施された部材である。従って、芯線１３と端子２０との接続部分では、異種金属が接触した状態となっており、この部分に塩水等の電解液が付着すると、異種金属接触腐食が発生し得る。 Here, the core wire 13 (element wire) of the electric wire 12 and the terminal 20 are made of different kinds of metals. For example, the core wire 13 is made of aluminum or an aluminum alloy containing aluminum as a main component. On the other hand, the terminal 20 is made of copper or a copper alloy containing copper as a main component (brass, etc.), or tin (Sn) plating on these members, or silver (Ag), copper (Cu), bismuth on tin. This is a member plated with a tin alloy to which (Bi) or the like is added. Therefore, the dissimilar metal is in contact with the connecting portion between the core wire 13 and the terminal 20, and when an electrolyte such as salt water adheres to this portion, dissimilar metal contact corrosion may occur.
　また、端子２０と電線１２との接続部分では、露出芯線部１３ａは次の各部で外部に露出している。すなわち、芯線圧着部２４と被覆圧着部２６との間で、露出芯線部１３ａの基端部が露出している。また、芯線圧着部２４と相手側接続部２８との間で、露出芯線部１３ａの先端部が露出している。さらに、芯線圧着部２４の一対の芯線圧着片２４ｂが露出芯線部１３ａにかしめられた状態で、一対の芯線圧着片２４ｂの先端部間に隙間が生じ得るため、この一対の芯線圧着片２４ｂの間で露出芯線部１３ａの中間部分が露出し得る。 Moreover, in the connection part of the terminal 20 and the electric wire 12, the exposed core part 13a is exposed outside at the following parts. That is, the base end portion of the exposed core wire portion 13a is exposed between the core wire crimp portion 24 and the coating crimp portion 26. Moreover, the front-end | tip part of the exposed core wire part 13a is exposed between the core wire crimping part 24 and the other party connection part 28. FIG. Further, a gap may be generated between the tip ends of the pair of core wire crimping pieces 24b in a state where the pair of core wire crimping pieces 24b of the core wire crimping portion 24 is caulked to the exposed core wire crimping portion 13a. In between, the intermediate part of the exposed core part 13a can be exposed.
　そこで、流動状態の防食剤１８Ｂを、露出芯線部１３ａのうち芯線圧着部２４に対して被覆圧着部２６に露出する基端側部分Ｑ１と、芯線圧着部２４の一対の芯線圧着片２４ｂの間の部分Ｑ２と、露出芯線部１３ａのうち芯線圧着部２４に対して被覆圧着部２６とは反対側に露出する先端側部分Ｑ３とに対して、供給する。そして、流動状態の防食剤１８Ｂがそれらの各部分Ｑ１、Ｑ２、Ｑ３の表面上で広がって被膜を形成し、この被膜を硬化させて（ここでは粘度を高めて）防食被膜１８を形成する。すると、それらの各部分Ｑ１、Ｑ２、Ｑ３が防食被膜１８で被覆されるため、端子２０と電線１２との接続部分に電解液が付着したとしても、当該電解液は、露出芯線部１３ａには接しない。このため、異種金属に対して電解液が付着した状態となることが抑制され、もって、異種金属接触腐食が抑制される。なお、防食被膜１８は、透明又は半透明であるが、これは必須ではない。また、防食被膜１８は、有色であってもよいし、無色であってもよい。 Therefore, the anticorrosive 18B in a fluidized state is between the proximal end side portion Q1 exposed to the covering crimping portion 26 with respect to the core wire crimping portion 24 in the exposed core wire portion 13a and the pair of core wire crimping pieces 24b of the core wire crimping portion 24. Of the exposed core wire portion 13a and the distal end side portion Q3 of the exposed core wire portion 13a exposed to the opposite side of the coated crimp portion 26 with respect to the core wire crimp portion 24. Then, the anticorrosive 18B in a fluid state spreads on the surface of each of the portions Q1, Q2, and Q3 to form a coating, and the coating is cured (in this case, the viscosity is increased) to form the anticorrosion coating 18. Then, since each of those portions Q1, Q2, and Q3 is covered with the anticorrosion coating 18, even if the electrolytic solution adheres to the connection portion between the terminal 20 and the electric wire 12, the electrolytic solution remains on the exposed core portion 13a. Do not touch. For this reason, it will be suppressed that it will be in the state where electrolyte solution adhered to a dissimilar metal, and, therefore, dissimilar metal contact corrosion is controlled. The anticorrosion coating 18 is transparent or translucent, but this is not essential. Further, the anticorrosion coating 18 may be colored or colorless.
　もっとも、端子２０と電線１２との接続部分の大型化を抑制し、かつ、防食剤１８Ｂの使用量を抑制するためには、微量の防食剤１８Ｂを、なるべく広範囲に供給できるようにすることが好ましい。そこで、ここでは、流動状態の防食剤１８Ｂを、各部分Ｑ１、Ｑ２Ｑ３に対して供給する際に、それらの部分の少なくとも１つの部分では、流動状態の防食剤１８Ｂを点状に供給する。すなわち、流動状態の防食剤１８Ｂを連続して供給するのではなく、断続的かつ部分的に上記各部分Ｑ１，Ｑ２、Ｑ３上に供給していく。点状に供給された流動状態の防食剤１８Ｂは、自己の粘度、露出芯線部１３ａに対する防食剤１８Ｂの濡れ性等に応じて、露出芯線部１３ａの表面上にも広がる。そして、異なる箇所において点状に供給された防食剤１８Ｂ同士が繋がって連続する被膜を形成する。この被膜が硬化する（粘度が高まる）ことで、露出芯線部１３ａのうち接続部分から露出する部分Ｑ１、Ｑ２、Ｑ３に、上記防食被膜１８を形成することができる。 But in order to suppress the enlargement of the connection part of the terminal 20 and the electric wire 12, and to suppress the usage-amount of the anticorrosive 18B, it is possible to supply a trace amount anticorrosive 18B as widely as possible. preferable. Therefore, here, when the fluidized anticorrosive 18B is supplied to each of the portions Q1 and Q2Q3, the fluidized anticorrosive 18B is supplied in a dotted manner in at least one of those portions. That is, the anticorrosive 18B in a fluid state is not continuously supplied, but is intermittently and partially supplied onto each of the parts Q1, Q2, and Q3. The anticorrosive agent 18B in a fluid state supplied in the form of dots spreads on the surface of the exposed core portion 13a according to its own viscosity, the wettability of the anticorrosive agent 18B with respect to the exposed core portion 13a, and the like. And the anticorrosive 18B supplied in the shape of a dot in a different location connects, and forms the continuous film. When the coating is cured (viscosity is increased), the anticorrosion coating 18 can be formed on portions Q1, Q2, and Q3 exposed from the connection portion of the exposed core portion 13a.
　なお、防食剤１８Ｂは、Ｑ１、Ｑ２、Ｑ３の周囲において、電線接続部２２の表面上にも広がっていてもよい。もっとも、防食剤１８Ｂが電線接続部２２の表面上に広がる領域はなるべく小さいことが好ましい。 In addition, the anticorrosive 18B may also spread on the surface of the wire connection part 22 around Q1, Q2, and Q3. But it is preferable that the area | region where the anticorrosive 18B spreads on the surface of the electric wire connection part 22 is as small as possible.
　ここでは、防食剤１８Ｂとして、温度によって粘度の大きさの変化が生じる防食剤１８Ｂを用いるものとして説明する。特にここでは、摂氏１３７度程度で広がり可能な程度に十分に粘性が低下する防食剤１８Ｂが用いられるものとして説明する。防食剤１８Ｂにおける温度と粘性との関係を示すグラフにおいて、摂氏１２０度から摂氏１３７度の間での曲線の勾配が、摂氏１２０度より小さい領域又は摂氏１３７度より大きい領域での曲線の勾配よりも大きい。 Here, the description will be made assuming that the anticorrosive 18B that changes in the magnitude of the viscosity depending on the temperature is used as the anticorrosive 18B. In particular, here, the description will be made assuming that the anticorrosive 18B whose viscosity is sufficiently lowered to be spread at about 137 degrees Celsius is used. In the graph showing the relationship between the temperature and the viscosity in the anticorrosive 18B, the slope of the curve between 120 degrees Celsius and 137 degrees Celsius is greater than the slope of the curve in an area less than 120 degrees Celsius or an area greater than 137 degrees Celsius. Is also big.
　このように、防食剤１８Ｂとして、温度によって粘度の大きさの変化又は固相液相間の相変化が生じる防食剤１８Ｂを用いる場合、光硬化性の防食剤１８Ｂなどと比べて供給中に防食剤１８Ｂが硬化又は粘度上昇しやすい。特に、上記のように点状に防食剤１８Ｂを供給すると、防食剤１８Ｂの温度が変化しやすくなるため、供給中に防食剤１８Ｂが硬化又は粘度上昇しやすい。そして、供給中に防食剤１８Ｂが硬化又は粘度上昇すると、異なる箇所において点状に供給された防食剤１８Ｂ同士が繋がって連続する被膜を形成することが難しくなる。従って、本実施形態に係る防食剤供給装置は、供給中に防食剤１８Ｂが硬化又は粘度上昇を生じにくくすることで、良好に防食被膜１８が形成された端子付電線１０を得ることができるようになっている。 As described above, when the anticorrosive agent 18B that causes a change in the magnitude of viscosity or a phase change between the solid and liquid phases is used as the anticorrosive agent 18B, the anticorrosion during the supply compared to the photocurable anticorrosive 18B or the like. The agent 18B tends to cure or increase in viscosity. In particular, when the anticorrosive agent 18B is supplied in the form of dots as described above, the temperature of the anticorrosive agent 18B is likely to change, and thus the anticorrosive agent 18B is likely to be cured or increased in viscosity during supply. And if the anticorrosive 18B hardens | cures or a viscosity rise during supply, it will become difficult to form the continuous coating by connecting the anticorrosive 18B supplied in the point form in a different location. Therefore, the anticorrosive agent supply apparatus according to the present embodiment makes it possible to obtain the terminal-attached electric wire 10 on which the anticorrosion coating 18 is well formed by making the anticorrosive agent 18B difficult to cure or increase in viscosity during supply. It has become.

　次に、防食剤供給装置について、図４乃至図７を参照しつつ説明する。図４は、実施形態に係る防食剤供給装置３０を示す概略斜視図である。図５は、実施形態に係る防食剤供給装置３０を示す概略側面図である。図６は、実施形態に係る防食剤供給装置３０を示す部分概略平面図である。図７は、供給部４０及び検知部１００を示す説明図である。 <Corrosion preventive supply device>
Next, the anticorrosive agent supply apparatus will be described with reference to FIGS. 4 to 7. FIG. 4 is a schematic perspective view showing the anticorrosive agent supply apparatus 30 according to the embodiment. FIG. 5 is a schematic side view showing the anticorrosive agent supply apparatus 30 according to the embodiment. FIG. 6 is a partial schematic plan view showing the anticorrosive agent supply apparatus 30 according to the embodiment. FIG. 7 is an explanatory diagram showing the supply unit 40 and the detection unit 100.
　防食剤供給装置３０は、第１機構３２と、第２機構５０と、電線搬送部９０とを備える。さらに防食剤供給装置３０は、第１機構３２、第２機構５０及び電線搬送部９０の各部の動作制御を行う制御部１１０を備えている。 The anticorrosive agent supply device 30 includes a first mechanism 32, a second mechanism 50, and an electric wire transport unit 90. Furthermore, the anticorrosive agent supply device 30 includes a control unit 110 that performs operation control of each of the first mechanism 32, the second mechanism 50, and the electric wire conveyance unit 90.
　以下では、防食剤供給装置３０において、電線搬送部９０によって複数の端子付電線１０が搬送される方向をｘ軸方向とする。この際、端子付電線１０は、ｘ軸方向と直交する方向に延在し、この方向をｙ軸方向とする。そして、ｘ軸方向及びｙ軸方向に直交する方向をｚ軸方向とする。ここでは、ｚ軸方向は鉛直方向に沿う方向である。 Hereinafter, in the anticorrosive supply device 30, the direction in which the plurality of electric wires 10 with a terminal are conveyed by the electric wire conveyance unit 90 is defined as an x-axis direction. At this time, the electric wire with terminal 10 extends in a direction orthogonal to the x-axis direction, and this direction is defined as a y-axis direction. A direction orthogonal to the x-axis direction and the y-axis direction is taken as a z-axis direction. Here, the z-axis direction is a direction along the vertical direction.
　第１機構３２は、搬送用チャック部３４と、撮像部３８と、供給部４０とを含み、これらが一体に移動可能とされている。ここでは、第１機構３２は、上記各部を一体的にｙ軸方向に移動可能に設けられたｙ軸方向移動機構３３を含む。従って、当該ｙ軸方向移動機構３３に搬送用チャック部３４と、撮像部３８と、供給部４０とが連結されている。搬送用チャック部３４と、撮像部３８と、供給部４０とは、ｙ軸方向に沿ってこの順に並んでいる。 The first mechanism 32 includes a conveyance chuck 34, an imaging unit 38, and a supply unit 40, which are movable together. Here, the 1st mechanism 32 contains the y-axis direction moving mechanism 33 provided so that the said each part was integrally movable to a y-axis direction. Accordingly, the transport chuck portion 34, the imaging portion 38, and the supply portion 40 are connected to the y-axis direction moving mechanism 33. The conveyance chuck unit 34, the imaging unit 38, and the supply unit 40 are arranged in this order along the y-axis direction.
　搬送用チャック部３４は、電線搬送部９０と後述する電線セット部５２との間で、電線１２を移送する部分である。ここでは、搬送用チャック部３４は、チャック部３５と、ｚ軸方向移動機構３６とを含む。ｙ軸方向移動機構３３にｚ軸方向移動機構３６が連結され、ｚ軸方向移動機構３６の先端にチャック部３５が設けられている。 The conveyance chuck portion 34 is a portion that transfers the electric wire 12 between the electric wire conveyance portion 90 and an electric wire setting portion 52 described later. Here, the conveyance chuck portion 34 includes a chuck portion 35 and a z-axis direction moving mechanism 36. A z-axis direction moving mechanism 36 is connected to the y-axis direction moving mechanism 33, and a chuck portion 35 is provided at the tip of the z-axis direction moving mechanism 36.
　ｚ軸方向移動機構３６は、ここでは、ｚ軸方向に沿った異なる３つの位置にチャック部３５を移動可能に形成されている。上記３つの位置のうち第１位置は、搬送用チャック部３４の標準位置であり、搬送用チャック部３４が動作を行わないときは、チャック部３５は第１位置に位置する。また、ｙ軸方向移動機構３３が動作する際にもチャック部３５は第１位置に位置し、ｙ軸方向移動機構３３によって移動中のチャック部３５が他の部材と干渉することが抑制されている。上記３つの位置のうち第２位置は、チャック部３５が電線セット部５２の後述する被覆チャック部５８との間で電線１２の受渡しをするときの位置である。上記３つの位置のうち第３位置は、チャック部３５が電線搬送部９０との間で電線１２の受渡しをするときの位置である。ここでは、第１位置、第２位置及び第３位置がｚ軸方向に沿って正の側から負の側に向けてこの順に設定される。つまりここでは、電線搬送部９０で搬送されている電線１２よりも、電線セット部５２にセットされている電線１２の方がｚ軸方向に高く位置する。 Here, the z-axis direction moving mechanism 36 is formed so that the chuck portion 35 can be moved to three different positions along the z-axis direction. The first position among the three positions is a standard position of the transport chuck section 34. When the transport chuck section 34 does not operate, the chuck section 35 is positioned at the first position. Also, when the y-axis direction moving mechanism 33 operates, the chuck portion 35 is located at the first position, and the y-axis direction moving mechanism 33 prevents the moving chuck portion 35 from interfering with other members. Yes. Of the three positions, the second position is a position when the chuck portion 35 delivers the electric wire 12 to and from a covering chuck portion 58 of the electric wire setting portion 52 described later. The third position among the three positions is a position when the chuck unit 35 delivers the electric wire 12 to and from the electric wire transport unit 90. Here, the first position, the second position, and the third position are set in this order from the positive side to the negative side along the z-axis direction. That is, here, the electric wire 12 set in the electric wire setting unit 52 is positioned higher in the z-axis direction than the electric wire 12 being conveyed by the electric wire conveyance unit 90.
　チャック部３５は、ここでは一対の挟持爪３５ａと、一対の挟持爪３５ａを開閉駆動する駆動部（図示省略）とで構成され、電線１２をチャック可能に形成されている。一対の挟持爪３５ａは、それぞれ中間部分が凹んだ形状に形成され、電線１２の延在方向に沿って異なる２箇所で電線１２を挟持可能となっている。これにより、チャック部３５で電線１２をチャックした際の電線１２の回転等が抑制される。 Here, the chuck portion 35 includes a pair of sandwiching claws 35a and a drive unit (not shown) that drives the pair of sandwiching claws 35a to open and close, and is formed so that the electric wire 12 can be chucked. The pair of sandwiching claws 35 a are formed in a shape in which an intermediate portion is recessed, and the wire 12 can be sandwiched at two different locations along the extending direction of the wire 12. Thereby, rotation of the electric wire 12 when the electric wire 12 is chucked by the chuck portion 35 is suppressed.
　搬送用チャック部３４を用いて電線１２は、以下のように電線搬送部９０又は電線セット部５２との間で受け渡される。即ち、ｙ軸方向移動機構３３によってｙ軸方向に沿って搬送用チャック部３４が電線搬送部９０又は電線セット部５２に応じた位置に移動する。この状態で、ｚ軸方向移動機構３６によってｚ軸方向に沿ってチャック部３５が電線１２に対応する位置に移動する。そして、この状態で、チャック部３５を開閉駆動することで、電線搬送部９０又は電線セット部５２との間で電線１２の受渡しが行われる。 The electric wire 12 is transferred between the electric wire conveyance unit 90 or the electric wire setting unit 52 as follows using the conveyance chuck unit 34. That is, the y-axis direction moving mechanism 33 moves the conveyance chuck unit 34 along the y-axis direction to a position corresponding to the electric wire conveyance unit 90 or the electric wire set unit 52. In this state, the z-axis direction moving mechanism 36 moves the chuck portion 35 to a position corresponding to the electric wire 12 along the z-axis direction. In this state, the chuck unit 35 is driven to open and close, so that the electric wire 12 is delivered to and from the electric wire transport unit 90 or the electric wire set unit 52.
　撮像部３８は、端子付電線１０の接続部分を撮像可能に設けられている。ここでは、撮像部３８は、ＣＣＤカメラ等によって構成される撮像カメラである。撮像部３８としては、２次元カメラが用いられてもよいし、ステレオカメラが用いられてもよい。ここでは、前者の例で説明する。ここでは、ｙ軸方向移動機構３３によってｙ軸方向に沿って撮像部３８が電線セット部５２に応じた位置に移動する。この状態で、撮像部３８が電線セット部５２にセットされた端子付電線１０を撮像することで、接続部分が撮像される。 The imaging part 38 is provided so that the connection part of the electric wire 10 with a terminal can be imaged. Here, the imaging unit 38 is an imaging camera configured by a CCD camera or the like. As the imaging unit 38, a two-dimensional camera may be used, or a stereo camera may be used. Here, the former example will be described. Here, the imaging unit 38 moves to a position corresponding to the wire setting unit 52 along the y-axis direction by the y-axis direction moving mechanism 33. In this state, the imaging unit 38 images the terminal-attached electric wire 10 set in the electric wire setting unit 52, whereby the connection portion is imaged.
　供給部４０は、防食剤１８Ｂを供給可能に設けられている。供給部４０は、吐出機構４１と、吐出機構移動機構４６とを含む。さらにここでは、供給部４０の周辺には、検知部１００と供給部加熱部８２とが設けられている。 The supply part 40 is provided so that the anticorrosive 18B can be supplied. The supply unit 40 includes a discharge mechanism 41 and a discharge mechanism moving mechanism 46.

Here, a description will be given assuming that a dispenser is provided as the discharge unit 42. Here, the dispenser can discharge a certain amount of the anticorrosive 18B with pressurization by air. In particular, here, the dispenser can eject the anticorrosive 18B drop by drop. The size of the discharged anticorrosive agent 18B is not particularly limited, but is preferably smaller than the width of the terminal 20. The size of the droplet of the anticorrosive agent 18B to be discharged is determined by, for example, the viscosity of the anticorrosive agent 18B, the size of the opening of the discharge portion 42, the degree of pressurization, and the like.

The terminal heating unit 84 is an example of a thermal mechanism. Here, the terminal heating unit 84 is provided so as to be able to heat the pair of clamping claws 55a of the mating connection portion chuck portion 55 and the pair of clamping claws 56a of the wire connection portion chuck portion 56, respectively. For example, the terminal heating unit 84 is configured by a heater or the like, and is incorporated in each of the holding claws 55a and 56a. The terminal heating unit 84 may be controlled such that the heating temperature can be adjusted in a plurality of stages, or only on / off switching may be controlled. Here, the terminal heating section 84 heats the terminal chuck section 54 so that the viscosity can be lowered to such an extent that it can be sufficiently spread when the anticorrosive 18B having viscosity adheres to the connection portion. ing.
　ここでは、防食剤１８Ｂとして、摂氏１３７度を超えたあたりで広がり可能な程度に十分に粘性が低下する防食剤１８Ｂが用いられるものとして説明する。特にここでは、防食剤１８Ｂにおける温度と粘性との関係を示すグラフにおいて、摂氏１２０度から摂氏１３７度の間での曲線の勾配が、摂氏１２０度より小さい領域又は摂氏１３７度より大きい領域での曲線の勾配よりも大きい。 Here, the description will be made assuming that the anticorrosive 18B having a sufficiently low viscosity is used as the anticorrosive 18B so that it can spread around 137 degrees Celsius. In particular, here, in the graph showing the relationship between the temperature and the viscosity of the anticorrosive 18B, the slope of the curve between 120 degrees Celsius and 137 degrees Celsius is in a region smaller than 120 degrees Celsius or larger than 137 degrees Celsius. Greater than the slope of the curve.
　この場合、端子２０は、防食剤１８Ｂが供給される直前の温度（以降、所望到達温度と称する）が、防食剤１８Ｂの粘性が十分に低下する温度よりも高い温度となるように加熱されることが好ましい。これにより、防食剤１８Ｂが十分に広がる前に防食剤１８Ｂの粘性が上昇してしまい、防食剤１８Ｂが十分に広がりきらないといった事態が生じることを抑制することができる。例えば、端子２０の所望到達温度は、摂氏１５０度乃至１７０度に設定される。もっとも、端子２０の所望到達温度は、上記に限られるものではない。端子２０の所望到達温度は、供給直前の防食剤１８Ｂの温度、及び防食剤１８Ｂ、端子２０、電線１２の各部の熱伝導性並びに融点等に基づいて、実験的、経験的に設定される値である。なお、ここでは、芯線と材料としてアルミニウムを用いているため、端子２０の所望到達温度は、摂氏２００度以下に設定されることが好ましい。 In this case, the terminal 20 is heated so that the temperature immediately before the anticorrosive agent 18B is supplied (hereinafter referred to as a desired temperature) is higher than the temperature at which the viscosity of the anticorrosive agent 18B sufficiently decreases. It is preferable. Thereby, before the anticorrosive 18B spreads sufficiently, it can suppress that the viscosity of the anticorrosive 18B rises and the situation where the anticorrosive 18B cannot fully spread arises. For example, the desired ultimate temperature of the terminal 20 is set to 150 degrees Celsius to 170 degrees Celsius. However, the desired ultimate temperature of the terminal 20 is not limited to the above. The desired ultimate temperature of the terminal 20 is a value set experimentally and empirically based on the temperature of the anticorrosive 18B immediately before supply, and the thermal conductivity and melting point of each part of the anticorrosive 18B, the terminal 20, and the wire 12. It is. Here, since aluminum is used as the core wire and the material, the desired ultimate temperature of the terminal 20 is preferably set to 200 degrees Celsius or less.
　端子チャック部５４を加熱する端子用加熱部８４は、端子２０の所望到達温度よりも高い温度で加熱することが好ましい。これにより、短時間で端子２０を所望到達温度に加熱することができる。ここでは、端子用加熱部８４は、摂氏３６０度で端子チャック部５４を加熱する。もっとも端子用加熱部の加熱温度は上記に限られるものではない。例えば、端子用加熱部８４は、所望到達温度よりも摂氏１４０度以上高い温度で加熱するとよい。なお、端子用加熱部８４は、相手側接続部チャック部５５を加熱する部分と、電線接続部チャック部５６を加熱する部分とが分かれて設けられ、これらを異なる温度で加熱するものであってもよい。この場合、相手側接続部チャック部５５を高い温度で加熱すると共に電線接続部チャック部５６を低い温度で加熱してもよいし、この逆であってもよい。 The terminal heating section 84 that heats the terminal chuck section 54 is preferably heated at a temperature higher than the desired temperature reached by the terminal 20. Thereby, the terminal 20 can be heated to desired desired temperature in a short time. Here, the terminal heating section 84 heats the terminal chuck section 54 at 360 degrees Celsius. However, the heating temperature of the terminal heating section is not limited to the above. For example, the terminal heating section 84 may be heated at a temperature 140 degrees Celsius or higher than the desired temperature. The terminal heating unit 84 is provided with a part for heating the mating connection part chuck part 55 and a part for heating the wire connection part chuck part 56, and heats them at different temperatures. Also good. In this case, the mating connector chuck 55 may be heated at a high temperature and the wire connector chuck 56 may be heated at a low temperature, or vice versa.
　端子用加熱部８４で加熱される相手側接続部チャック部５５及び電線接続部チャック部５６は、例えば金属など、熱伝導性の良い部材で形成されていることが好ましい。 It is preferable that the counterpart connection portion chuck portion 55 and the wire connection portion chuck portion 56 heated by the terminal heating portion 84 are formed of a member having good thermal conductivity, such as metal.
　吸引機構７０は、接続部分に供給された防食剤１８Ｂの余剰分を吸引する。吸引機構７０は、吸引部７２と、吸引部移動機構（図示省略）とを含む。 The suction mechanism 70 sucks the surplus of the anticorrosive 18B supplied to the connection part. The suction mechanism 70 includes a suction part 72 and a suction part moving mechanism (not shown).
　吸引部７２は、防食剤１８Ｂの余剰分を吸引する部分である。ここでは、吸引部７２は、吸引口７３ａを含む吸引本体部７３と、吸引口７３ａに設けられた吸引用当接部７７とを含む。 The suction part 72 is a part that sucks an excess of the anticorrosive 18B. Here, the suction portion 72 includes a suction body portion 73 including a suction port 73a and a suction contact portion 77 provided in the suction port 73a.
　吸引本体部７３は、例えば、筒状に形成され、両端が開口している。吸引本体部７３の両端開口のうち一方が吸引口７３ａをなしている。吸引口７３ａは上方を向いている。吸引本体部７３が接続部分の下方に位置するため、吸引口７３ａは接続部分を向いている。従って、ここでは、吸引部７２は、接続部分の下方から防食剤１８Ｂの余剰分を吸引する。吸引本体部７３には、吸引駆動部７５が接続される。吸引駆動部７５は、パイプ７６を介して吸引本体部７３と接続される。このとき、パイプ７６は吸引本体部７３の側面に形成される開口に接続される。側面の開口は、吸引本体部７３の両端開口を結ぶ通路に連通する。ここでは、吸引駆動部７５によって、吸引本体部７３に向けて圧縮空気が送られる。当該圧縮空気は、パイプ７６から吸引本体部７３の両端開口のうち他方、つまり下方を向く開口に向けて吐出される。この圧縮空気の流れの影響によって、吸引口７３ａ近傍の防食剤１８Ｂの余剰分が吸引本体部７３内に吸引される。吸引口７３ａから吸引本体部７３内に吸引された防食剤１８Ｂの余剰分は、下方を向く開口から下方に排出される。下方を向く開口の下方には、排出された防食剤１８Ｂの余剰分を回収する回収部１２０が設けられるとよい。回収部１２０で回収された防食剤１８Ｂの余剰分は、廃棄されてもよいし、再利用されてもよい。 The suction main body 73 is formed in a cylindrical shape, for example, and both ends are open. One of the openings at both ends of the suction body 73 forms a suction port 73a. The suction port 73a faces upward. Since the suction main body 73 is located below the connection portion, the suction port 73a faces the connection portion. Therefore, here, the suction part 72 sucks the surplus of the anticorrosive 18B from below the connection part. A suction drive unit 75 is connected to the suction body 73. The suction drive unit 75 is connected to the suction body unit 73 via the pipe 76. At this time, the pipe 76 is connected to an opening formed on the side surface of the suction main body 73. The opening on the side surface communicates with a passage connecting both end openings of the suction main body 73. Here, compressed air is sent toward the suction main body 73 by the suction drive unit 75. The compressed air is discharged from the pipe 76 toward the other of the openings at both ends of the suction main body 73, that is, toward the opening facing downward. Due to the influence of the flow of the compressed air, the surplus of the anticorrosive 18B in the vicinity of the suction port 73a is sucked into the suction body 73. The surplus of the anticorrosive 18B sucked into the suction main body 73 from the suction port 73a is discharged downward from the opening facing downward. A collection unit 120 that collects the excess of the discharged anticorrosive 18B may be provided below the opening facing downward. The surplus of the anticorrosive 18B collected by the collection unit 120 may be discarded or reused.
　吸引本体部７３は吸引本体部加熱部８６によって加熱される。ここでは、吸引本体部加熱部８６として吸引本体部７３に当接してこれを加熱するヒータが設けられる。例えば、棒状のヒータが、吸引本体部７３の筒部の外周側に埋め込まれる。吸引本体部７３は吸引本体部加熱部８６によって加熱されることにより、吸引本体部７３内に吸引された防食剤１８Ｂの余剰分が吸引本体部７３の内周面などに留まり難くなり、下方を向く開口から下方に排出され易くなる。 The suction body part 73 is heated by the suction body part heating part 86. Here, a heater that abuts on and heats the suction main body 73 as the suction main body heating section 86 is provided. For example, a rod-shaped heater is embedded on the outer peripheral side of the cylindrical portion of the suction main body 73. The suction main body 73 is heated by the suction main body heating section 86, so that the excess portion of the anticorrosive 18 </ b> B sucked into the suction main body 73 becomes difficult to stay on the inner peripheral surface of the suction main body 73, It becomes easy to discharge downward from the opening that faces.
　吸引用当接部７７は、端子２０と当接する部分である。ここでは、吸引用当接部７７は、電線接続部２２の下面、つまり底板部２３ａ、２４ａ、２５ａ、２６ａの少なくとも一部の外向き面に当接する。特にここでは、吸引用当接部７７は、底板部２５ａの外向き面を含む部分に当接するように設けられている。吸引用当接部７７は、板バネ状に形成されている。吸引用当接部７７は、平面の一部がｚ軸方向に突出した湾曲面状に形成されている。吸引用当接部７７は、ｚ軸方向に弾性変形可能に設けられている。吸引用当接部７７は、吸引口７３ａに対してｚ軸方向に突出する態様で吸引口７３ａの上方に設けられている。 The suction contact portion 77 is a portion that contacts the terminal 20. Here, the suction contact portion 77 contacts the lower surface of the wire connection portion 22, that is, at least a part of the outward surface of the bottom plate portions 23a, 24a, 25a, and 26a. In particular, here, the suction contact portion 77 is provided so as to contact a portion including the outward surface of the bottom plate portion 25a. The suction contact portion 77 is formed in a leaf spring shape. The suction contact portion 77 is formed in a curved surface shape in which a part of a plane protrudes in the z-axis direction. The suction contact portion 77 is provided so as to be elastically deformable in the z-axis direction. The suction contact portion 77 is provided above the suction port 73a so as to protrude in the z-axis direction with respect to the suction port 73a.
　吸引本体部加熱部８６で加熱される吸引本体部７３及び吸引本体部７３に取付けられ端子２０に当接する吸引用当接部７７は、例えば金属など、熱伝導性の良い部材で形成されていることが好ましい。 The suction body part 73 heated by the suction body part heating part 86 and the suction contact part 77 attached to the suction body part 73 and contacting the terminal 20 are formed of a member having good thermal conductivity such as metal. It is preferable.
　吸引部移動機構は、吸引部７２をｚ軸方向に沿って往復移動させる。例えば、吸引部移動機構が駆動していない時には、吸引用当接部７７が端子２０の下方であって端子２０と当接しない位置に吸引部７２が位置する。そして、接続部分に供給された防食剤１８Ｂの余剰分を吸引する時に、吸引部移動機構を駆動することによって、吸引用当接部７７が端子２０の下方に当接する位置に吸引部７２が位置する。従ってここでは、吸引部移動機構は上記２地点間で吸引部７２を往復移動させる。 The suction part moving mechanism reciprocates the suction part 72 along the z-axis direction. For example, when the suction part moving mechanism is not driven, the suction part 72 is located at a position where the suction contact part 77 is below the terminal 20 and does not contact the terminal 20. Then, when the surplus of the anticorrosive 18B supplied to the connection portion is sucked, the suction portion 72 is positioned at a position where the suction contact portion 77 contacts the lower side of the terminal 20 by driving the suction portion moving mechanism. To do. Accordingly, here, the suction part moving mechanism reciprocates the suction part 72 between the two points.
　電線搬送部９０は、ｘ軸方向に並ぶ電線１２をこの方向に搬送する。ここでは、電線搬送部９０は、電線支持部９２と、電線支持部移動機構９４とを含む。 The electric wire conveyance unit 90 conveys the electric wires 12 arranged in the x-axis direction in this direction. Here, the electric wire conveyance unit 90 includes an electric wire support portion 92 and an electric wire support portion moving mechanism 94.
　電線支持部９２は、ｙ軸方向に相互に平行に延びる複数の電線１２がｘ軸方向に並んだ状態で、支持可能である。ここでは、電線支持部９２として、長尺棒状に形成された支持ブロック９３ａと支持ブロック９３ａの一面に設けられた複数対の支持爪９３ｂとを有するセットバー９３が用いられている。各対の支持爪９３ｂは、電線１２が支持ブロック９３ａの長手方向と交差する方向に延びる姿勢で電線１２を挟持可能に形成されている。そして、複数対の支持爪９３ｂが支持ブロック９３ａの長手方向に並んでいる。セットバー９３は支持ブロック９３ａの長手方向がｘ軸方向に沿う態様で、ｘ軸方向に搬送される。支持ブロック９３ａの長手方向がｘ軸方向に沿った状態で、各対の支持爪９３ｂは、チャック部３５の凹部に収める形状に形成されている。従って、チャック部３５は、各対の支持爪９３ｂに挟持された部分に対してｙ軸方向に沿った前後の部分を挟持可能とされている。支持爪９３ｂは、弾性力によって電線１２を把持する。より詳細には、支持爪９３ｂは、支持ブロック９３ａに対する立設方向（ここではｚ軸方向）に沿って電線１２が押し付けられることで、開閉可能に設けられている。 The electric wire support portion 92 can be supported in a state where a plurality of electric wires 12 extending in parallel with each other in the y-axis direction are arranged in the x-axis direction. Here, as the wire support portion 92, a set bar 93 having a support block 93a formed in a long bar shape and a plurality of pairs of support claws 93b provided on one surface of the support block 93a is used. Each pair of support claws 93b is formed so that the electric wire 12 can be clamped in a posture in which the electric wire 12 extends in a direction intersecting the longitudinal direction of the support block 93a. A plurality of pairs of support claws 93b are arranged in the longitudinal direction of the support block 93a. The set bar 93 is conveyed in the x-axis direction such that the longitudinal direction of the support block 93a is along the x-axis direction. Each pair of support claws 93 b is formed in a shape that can be received in the recess of the chuck portion 35 in a state where the longitudinal direction of the support block 93 a is along the x-axis direction. Therefore, the chuck portion 35 can sandwich the front and rear portions along the y-axis direction with respect to the portion sandwiched between the pair of support claws 93b. The support claw 93b grips the electric wire 12 by an elastic force. More specifically, the support claw 93b is provided to be openable and closable by pressing the electric wire 12 along a standing direction (here, the z-axis direction) with respect to the support block 93a.
　電線支持部移動機構９４は、セットバー９３を搬送する。ここでは、曲げ変形可能なリンク機構９４ａの延在方向一端がセットバー９３を支持する部材（図示省略）に連結される。リンク機構９４ａの他端は、図示省略の固定フレーム等に連結される。リンク機構９４ａの一端及び他端はｚ軸方向に離れた位置に設けられると共に、一端及び他端からｘ軸方向に沿って同じ向きに延在し、延在方向中間部分で曲げられている。従って、リンク機構９４ａはｙ軸方向から見て、Ｕ字状又はＪ字状を呈する。そして、リンク機構９４ａの一端（他端）から曲げ部分までの距離が変わることで、固定フレームに対して、セットバー９３がｘ軸方向に搬送される。セットバー９３は、例えば、セットバー９３を支持する部材に対して着脱可能に設けられることが考えられる。これにより、電線搬送部９０に対して電線１２をセットバー９３ごと供給又は排出可能となる。電線搬送部９０は、対の支持爪９３ｂの間隔の整数倍分セットバー９３を送ることが可能であるとよい。また、電線搬送部９０には、搬送中の電線１２において支持爪９３ｂに支持された部分に対してｙ軸方向に沿った一方側部分及び他方側部分の少なくとも一方をガイド可能なガイド部材が設けられるとよい。 The electric wire support part moving mechanism 94 conveys the set bar 93. Here, one end in the extending direction of the link mechanism 94a capable of bending deformation is connected to a member (not shown) that supports the set bar 93. The other end of the link mechanism 94a is connected to a fixed frame (not shown). One end and the other end of the link mechanism 94a are provided at positions separated from each other in the z-axis direction, extend from the one end and the other end in the same direction along the x-axis direction, and are bent at an intermediate portion in the extending direction. Therefore, the link mechanism 94a has a U shape or a J shape when viewed from the y-axis direction. The set bar 93 is conveyed in the x-axis direction with respect to the fixed frame by changing the distance from one end (the other end) of the link mechanism 94a to the bent portion. It is conceivable that the set bar 93 is detachably provided on a member that supports the set bar 93, for example. Thereby, the electric wire 12 can be supplied or discharged together with the set bar 93 to the electric wire conveying unit 90. The electric wire conveyance part 90 is good to be able to send the set bar 93 by the integral multiple of the space | interval of a pair of support nail | claw 93b. Further, the electric wire conveyance unit 90 is provided with a guide member capable of guiding at least one of the one side portion and the other side portion along the y-axis direction with respect to the portion supported by the support claw 93b in the electric wire 12 being conveyed. It should be done.
　もっとも、電線支持部移動機構９４の構成は上記に限られるものではなく、例えば、無端環状のチェーン機構等によって電線支持部９２を移動させるものであってもよい。 However, the configuration of the wire support portion moving mechanism 94 is not limited to the above, and the wire support portion 92 may be moved by, for example, an endless annular chain mechanism.
　制御部１１０は、第１機構３２、第２機構５０、電線搬送部９０に接続されている。制御部１１０の制御下で、第１機構３２、第２機構５０、電線搬送部９０の各部が防食剤１８Ｂの供給に係る加工動作を行う。さらにここでは、制御部は、検査制御ユニットとしての機能を担う。 The control unit 110 is connected to the first mechanism 32, the second mechanism 50, and the electric wire transport unit 90. Under the control of the control unit 110, each of the first mechanism 32, the second mechanism 50, and the electric wire transport unit 90 performs a processing operation related to the supply of the anticorrosive 18B. Further, here, the control unit functions as an inspection control unit.
　防食剤供給状態検査装置のハードウェア構成について、図８を参照しながら説明する。図８は、防食剤供給状態検査装置のハードウェア構成を示すブロック図である。 The hardware configuration of the anticorrosive agent supply state inspection apparatus will be described with reference to FIG. FIG. 8 is a block diagram illustrating a hardware configuration of the anticorrosive agent supply state inspection apparatus.
　上述したように、防食剤供給状態検査装置は、防食剤供給装置３０に組み込まれている。ここでは、防食剤供給状態検査装置は、主として上記撮像部３８、検知部１００及び制御部１１０とで構成される。 As described above, the anticorrosive agent supply state inspection device is incorporated in the anticorrosive agent supply device 30. Here, the anticorrosive agent supply state inspection apparatus mainly includes the imaging unit 38, the detection unit 100, and the control unit 110.
　制御部１１０は、検知部１００が取得した検知結果を解析することによって、端子付電線１０の供給状態の合否を判定する。制御部１１０は、例えば、ＣＰＵ１１１、ＲＯＭ１１２、ＲＡＭ１１３、通信部１１４、記憶装置１１５等が、バスライン１１６を介して相互接続された一般的なコンピュータによって構成されている。ここにおいて、ＲＯＭ１１２は基本プログラム等を格納しており、ＲＡＭ１１３はＣＰＵ１１１が所定の処理を行う際の作業領域として供される。通信部１１４は、ＬＡＮ等の通信回線を介したデータ通信機能を有する。記憶装置１１５は、フラッシュメモリ、あるいは、ハードディスク装置等の不揮発性の記憶装置によって構成されている。 The control unit 110 determines whether the supply state of the terminal-attached electric wire 10 is acceptable by analyzing the detection result acquired by the detection unit 100. The control unit 110 includes, for example, a general computer in which a CPU 111, a ROM 112, a RAM 113, a communication unit 114, a storage device 115, and the like are interconnected via a bus line 116. Here, the ROM 112 stores basic programs and the like, and the RAM 113 is used as a work area when the CPU 111 performs predetermined processing. The communication unit 114 has a data communication function via a communication line such as a LAN. The storage device 115 is configured by a nonvolatile storage device such as a flash memory or a hard disk device.
　記憶装置１１５にはプログラムＰｒが格納されている。ここでは、プログラムＰｒとして、例えば、防食剤１８Ｂの供給に係る供給プログラムＰｒ１及び供給状態の検査に係る検査プログラムＰｒ２等が格納されている。この検査プログラムＰｒ２に記述された手順に従って、主制御部としてのＣＰＵ１１１が演算処理を行うことにより、防食剤供給状態検査装置の各種機能が実現されるように構成されている。 The storage device 115 stores a program Pr. Here, as the program Pr, for example, a supply program Pr1 related to the supply of the anticorrosive 18B, an inspection program Pr2 related to the supply state inspection, and the like are stored. Various functions of the anticorrosive agent supply state inspection apparatus are realized by the CPU 111 as the main control unit performing arithmetic processing according to the procedure described in the inspection program Pr2.
　また、ここでは、記憶装置１１５には、合格判定基準Ｍが格納されている。ここでは、例えば、合格判定基準Ｍとして、供給範囲における理想的な防食剤１８Ｂの供給位置及びその位置に対する許容公差が設定される。例えば、合格判定基準Ｍは、図１３の黒点に示すように、マップ状に設定される。 In addition, here, the acceptance criterion M is stored in the storage device 115. Here, for example, as the acceptance criterion M, an ideal supply position of the anticorrosive 18B in the supply range and an allowable tolerance for the position are set. For example, the acceptance criterion M is set in a map as shown by the black dots in FIG.
　プログラムＰｒは、通常、予め記憶装置１１５等のメモリに格納されて使用されるものであるが、ＣＤ－ＲＯＭあるいはＤＶＤ－ＲＯＭ、外部のフラッシュメモリ等の記録媒体に記録された形態（プログラムプロダクト）で提供され（あるいは、ネットワークを介した外部サーバからのダウンロードなどにより提供され）、追加的または交換的に記憶装置１１５等のメモリに格納されるものであってもよい。 The program Pr is normally stored and used in advance in a memory such as the storage device 115, but is recorded in a recording medium such as a CD-ROM or DVD-ROM or an external flash memory (program product). (Or provided by downloading from an external server via a network) and may be additionally or exchanged stored in a memory such as the storage device 115.
　もっとも、制御部１１０において実現される一部あるいは全部の機能は、専用の論理回路等でハードウェア的に実現されてもよい。 However, some or all of the functions realized in the control unit 110 may be realized in hardware by a dedicated logic circuit or the like.
　制御部１１０には、さらに、入力部１１８、および、表示部１１９が接続されている。入力部１１８は、例えば、キーボード、マウス、各種スイッチ、タッチパネル等の少なくとも１つを含む入力デバイスであり、オペレータからの各種の操作（コマンドや各種データの入力といった操作）を受け付ける。表示部１１９は、液晶表示部、ランプ等により構成されており、ＣＰＵ１１１による制御の下、各種の情報を表示する。 Further, an input unit 118 and a display unit 119 are connected to the control unit 110. The input unit 118 is an input device including at least one of a keyboard, a mouse, various switches, a touch panel, and the like, for example, and accepts various operations (operations such as inputting commands and various data) from the operator. The display unit 119 includes a liquid crystal display unit, a lamp, and the like, and displays various types of information under the control of the CPU 111.
　制御部１１０が備える機能構成について、図９を参照しながら説明する。図９は、制御部１１０において実現される機能ブロック図である。 The functional configuration of the control unit 110 will be described with reference to FIG. FIG. 9 is a functional block diagram realized in the control unit 110.
　制御部１１０は、撮像制御部１１７ａと、供給位置検出部１１７ｂと、検知制御部１１７ｃと、判定部１１７ｄとを備えている。これら各機能部は、上述したとおり、例えば、ＣＰＵ１１１が検査プログラムＰｒ２に従って所定の演算処理を行うことにより実現される。 The control unit 110 includes an imaging control unit 117a, a supply position detection unit 117b, a detection control unit 117c, and a determination unit 117d. As described above, these functional units are realized, for example, by the CPU 111 performing predetermined arithmetic processing according to the inspection program Pr2.
　撮像制御部１１７ａは、撮像部３８を制御して、検査対象となる端子付電線１０を撮像させる。つまり、撮像部３８と撮像制御部１１７ａとが協働して、検査対象となる端子付電線１０を撮像して撮像データを取得する撮像データ取得部を構成する。ただし、検査対象となる端子付電線１０は、その延在方向が定められた軸に沿うような姿勢とされるとともに、接続部分における露出芯線部１３ａを真上に向けた状態で配置され、撮像部３８は、このような姿勢で配置された端子付電線１０を真上から撮像する。 The imaging control unit 117a controls the imaging unit 38 to image the terminal-attached electric wire 10 to be inspected. That is, the imaging unit 38 and the imaging control unit 117a cooperate to constitute an imaging data acquisition unit that images the terminal-attached electric wire 10 to be inspected and acquires imaging data. However, the terminal-attached electric wire 10 to be inspected is placed in a posture such that its extending direction is along the axis in which the extension direction is determined, and the exposed core portion 13a in the connection portion is disposed directly above, and imaging is performed. The part 38 images the electric wire with terminal 10 arranged in such a posture from directly above.
　供給位置検出部１１７ｂは、撮像部３８によって取得された端子付電線１０の撮像データ内において、防食剤１８Ｂを供給する位置を検出する。以下では、供給位置検出部１１７ｂは、端子２０における芯線圧着片２４ｂの延在方向縁部を検出するものとして説明する。撮像データ内において芯線圧着片２４ｂの延在方向縁部の位置は、これを境に輝度が大きく変化する位置となっている。このため供給位置検出部１１７ｂは、輝度の変化に基づいて当該縁部の位置を特定することができる。そして、制御部１１０は、当該芯線圧着片２４ｂの延在方向縁部の位置を基準位置に設定し、この基準位置に基づいて予め与えられた供給プログラムＰｒ１に従って防食剤１８Ｂの供給を行う。例えば、供給プログラムＰｒ１は、基準位置からの吐出機構４１の移動の軌跡と、移動中のどの位置で防食剤１８Ｂの吐出を行うかと、を対応付けたプログラムであることが考えられる。 The supply position detection unit 117b detects the position where the anticorrosive 18B is supplied in the imaging data of the terminal-attached electric wire 10 acquired by the imaging unit 38. Hereinafter, the supply position detection unit 117b will be described as detecting the extending direction edge of the core wire crimping piece 24b in the terminal 20. In the imaging data, the position of the edge in the extending direction of the core wire crimping piece 24b is a position where the luminance greatly changes with this as a boundary. For this reason, the supply position detection part 117b can specify the position of the said edge part based on the change of a brightness | luminance. And the control part 110 sets the position of the extension direction edge part of the said core wire crimping piece 24b to a reference | standard position, and supplies the anticorrosive 18B according to the supply program Pr1 given previously based on this reference | standard position. For example, the supply program Pr1 may be a program that associates the trajectory of the movement of the discharge mechanism 41 from the reference position with the position at which the anticorrosive 18B is discharged during the movement.
　なお、供給位置検出部１１７ｂが、端子２０における芯線圧着片２４ｂの延在方向縁部以外の位置（以下、予定検出位置と称する）であって、輝度の変化に基づいて、当該予定検出位置を特定することが難しい場合は、例えば、以下のようにして予定検出位置を検出することが考えられる。 The supply position detection unit 117b is a position (hereinafter referred to as a planned detection position) other than the extending direction edge of the core wire crimping piece 24b in the terminal 20, and the planned detection position is determined based on a change in luminance. When it is difficult to specify, for example, it is conceivable to detect the scheduled detection position as follows.
　即ち、防食剤供給状態検査装置においては、予め、検査対象となる端子付電線１０と同じ形状タイプの端子付電線の撮像データ内に、理想的な寸法の予定検出位置を理想的な位置に設定するとともに、この端子付電線内の定められた箇所を代表箇所として規定して、この代表箇所の位置と、理想的な予定検出位置との相対位置関係を登録する処理が行われている。供給位置検出部１１７ｂは、検査対象となる端子付電線１０の撮像データが取得されると、当該撮像データ内から、代表箇所を検索してその位置を特定し、特定された位置に対して予め記憶されている相対位置関係にある各頂点位置から規定される位置を、予定検出位置として設定する。設定に用いられる代表箇所は、一意に規定される箇所であればよく、例えば、上記芯線圧着片２４ｂの端縁のように輝度の変化に基づいて特定容易な位置を、代表箇所とすることができる。 That is, in the anticorrosive agent supply state inspection device, the planned detection position of the ideal dimension is set to the ideal position in advance in the imaging data of the electric wire with terminal of the same shape type as the electric wire with terminal 10 to be inspected. At the same time, a process is performed in which a predetermined location in the electric wire with terminal is defined as a representative location, and the relative positional relationship between the position of the representative location and the ideal planned detection position is registered. When the imaging data of the terminal-attached electric wire 10 to be inspected is acquired, the supply position detection unit 117b searches for a representative location from the imaging data and specifies the position, and the supply position detection unit 117b in advance with respect to the specified position. A position defined from each vertex position in the stored relative positional relationship is set as a scheduled detection position. The representative location used for setting may be a location that is uniquely defined. For example, a position that is easily specified based on a change in luminance, such as the edge of the core wire crimping piece 24b, may be used as the representative location. it can.
　検知制御部１１７ｃは、検知部１００を制御して、吐出部４２から吐出される防食剤１８Ｂの粒を検知させる。つまり、検知部１００と検知制御部１１７ｃとが協働して、防食剤１８Ｂの粒を検知して検知データを取得する検知データ取得部を構成する。ここでは、対象となる防食剤１８Ｂの粒の状態は、吐出部４２から吐出された後、接続部分に付着する前の状態であり、検知部１００は、このような状態にある防食剤１８Ｂの粒に対して側方から投光し検知する。 The detection control unit 117c controls the detection unit 100 to detect the particles of the anticorrosive 18B discharged from the discharge unit 42. That is, the detection part 100 and the detection control part 117c cooperate, and the detection data acquisition part which detects the particle | grains of the anticorrosive 18B and acquires detection data is comprised. Here, the state of the particles of the target anticorrosive 18B is a state before being ejected from the ejection part 42 and before adhering to the connection portion, and the detection unit 100 is the state of the anticorrosive 18B in such a state. Light is detected from the side of the grain and detected.
　判定部１１７ｄは、検知部１００の検知結果と、供給位置検出部１１７ｂの検出出力と、記憶部１１５に記憶された合格判定基準Ｍとに基づいて、端子付電線１０の状態の合否を判定する。具体的には、例えば、検知部１００検知結果と供給位置検出部１１７ｂの検出出力とに基づいて、防食剤１８Ｂの供給位置がマッピングされる。そして、判定部１１７ｄは、作成されたマップを記憶部１１５に記憶された合格判定基準Ｍと比較し、合格判定基準Ｍにおける各供給位置の許容公差内に、防食剤１８Ｂの粒が供給されている場合に、当該端子付電線１０の供給状態に合格の判定を与え、そうでない場合に不合格の判定を与える。 The determination unit 117d determines pass / fail of the state of the terminal-attached electric wire 10 based on the detection result of the detection unit 100, the detection output of the supply position detection unit 117b, and the pass determination criterion M stored in the storage unit 115. . Specifically, for example, the supply position of the anticorrosive 18B is mapped based on the detection result of the detection unit 100 and the detection output of the supply position detection unit 117b. And the determination part 117d compares the created map with the acceptance criterion M memorize | stored in the memory | storage part 115, and the particle | grains of the anticorrosive 18B are supplied within the tolerance of each supply position in the acceptance criterion M. If it is, a pass determination is given to the supply state of the terminal-attached electric wire 10, and a fail determination is given otherwise.
　防食剤供給装置３０には、各加熱部８２，８４，８６の各加熱対象の温度を測定可能な温度センサが設けられることが考えられる。この場合、温度センサの測定温度に基づいて制御部１１０によって各加熱部８２，８４，８６の動作が制御されるとよい。また、端子２０の温度を測定可能な温度センサが設けられることも考えられる。この場合、当該温度センサの測定温度に基づいて制御部１１０によって端子用加熱部８４及び端子チャック部５４の動作が制御されるとよい。 It is conceivable that the anticorrosive supply device 30 is provided with a temperature sensor capable of measuring the temperature of each heating target of each heating unit 82, 84, 86. In this case, the operation of each heating unit 82, 84, 86 may be controlled by the control unit 110 based on the temperature measured by the temperature sensor. It is also conceivable that a temperature sensor capable of measuring the temperature of the terminal 20 is provided. In this case, the operations of the terminal heating unit 84 and the terminal chuck unit 54 may be controlled by the control unit 110 based on the measured temperature of the temperature sensor.
　また、電線セット部５２に端子付電線１０がセットされたことを検知可能なセット状態検知部１０６が設けられてもよい。セット状態検知部１０６は、例えば、端子付電線１０のうち電線セット部５２から後方に延びる部分を支持する後端側支持部１０８に設けられる。図４に示す例では、セット状態検知部１０６は、投光部と受光部とを含む光センサで構成され、後端側支持部１０８に支持された端子付電線１０が存在するか否かを検知する。この場合、制御部１１０は、セット状態検知部１０６が端子付電線１０を検知した際に、防食剤１８Ｂの供給に係る動作指令を各部に出すことが考えられる。 Further, a set state detection unit 106 capable of detecting that the terminal-attached electric wire 10 is set in the electric wire setting unit 52 may be provided. The set state detection part 106 is provided in the rear end side support part 108 which supports the part extended back from the electric wire set part 52 among the electric wires 10 with a terminal, for example. In the example illustrated in FIG. 4, the set state detection unit 106 includes an optical sensor including a light projecting unit and a light receiving unit, and determines whether or not the terminal-attached electric wire 10 supported by the rear end side support unit 108 exists. Detect. In this case, when the set state detection part 106 detects the electric wire 10 with a terminal, the control part 110 can consider giving the operation command which concerns on supply of the anticorrosive 18B to each part.
　＜製造方法＞
　次に、図１０乃至図１９を参照しつつ上記防食剤供給装置３０を用いた端子付電線１０の製造方法について説明する。図１０は、防食剤供給装置３０を用いた端子付電線１０の製造工程の流れを説明する図である。図１１、図１２及び図１５乃至図１９は、端子付電線１０の製造工程を示す説明図である。図１３は、端子付電線１０に対する防食剤１８Ｂの供給位置の例を示す説明図である。 <Manufacturing method>
Next, the manufacturing method of the electric wire 10 with a terminal using the said anticorrosive agent supply apparatus 30 is demonstrated, referring FIG. 10 thru | or FIG. FIG. 10 is a diagram for explaining the flow of the manufacturing process of the terminal-attached electric wire 10 using the anticorrosive supply device 30. 11, 12, and 15 to 19 are explanatory views showing a manufacturing process of the terminal-attached electric wire 10. FIG. 13 is an explanatory diagram illustrating an example of a supply position of the anticorrosive 18 </ b> B with respect to the terminal-attached electric wire 10.
　まずステップＳ０１として、電線１２を供給する。ここでは、電線搬送部９０が供給対象の電線１２をｘ軸方向に沿った所定の位置に搬送する。この状態で、図１１に示すように搬送用チャック部３４によって電線搬送部９０に支持された電線１２が電線セット部５２に搬送されてセットされる。 First, as step S01, the electric wire 12 is supplied. Here, the electric wire conveyance part 90 conveys the electric wire 12 to be supplied to a predetermined position along the x-axis direction. In this state, as shown in FIG. 11, the electric wire 12 supported by the electric wire conveying portion 90 by the conveying chuck portion 34 is conveyed and set to the electric wire setting portion 52.
　より詳細には、ｙ軸方向移動機構３３を駆動させることによって、搬送用チャック部３４を電線搬送部９０のセットバー９３の支持爪９３ｂの上方に位置させる。この状態で、ｚ軸方向移動機構３６及びチャック開閉用の駆動部を駆動させることによって、搬送用チャック部３４が電線搬送部９０から電線１２を受け取る。次に、ｙ軸方向移動機構３３を駆動させることによって、電線搬送部９０から電線１２を受け取った搬送用チャック部３４を、被覆チャック部５８の上方に位置させる。この状態で、ｚ軸方向移動機構３６及びチャック開閉用の駆動部を駆動させることによって、搬送用チャック部３４から被覆チャック部５８に電線１２を受け渡す。この際、端子２０は支持部６８に支持される。また、この受渡し動作の前、より具体的には、搬送用チャック部３４が被覆チャック部５８の上方に位置する直前に端子押え部６１は、一旦受渡しの邪魔にならない位置に位置するように回動する。そして、受渡し動作中又は終わった後、より具体的には、ｚ軸方向移動機構３６を駆動させることによって被覆チャック部５８の挟持爪５８ａがチャック部３５の挟持爪３５ａの凹部に収まる位置に位置するようにチャック部３５を移動させた直後に、端子２０を押さえ可能な位置に戻るように回動する。 More specifically, by driving the y-axis direction moving mechanism 33, the conveyance chuck portion 34 is positioned above the support claw 93 b of the set bar 93 of the electric wire conveyance unit 90. In this state, by driving the z-axis direction moving mechanism 36 and the chuck opening / closing drive unit, the transfer chuck unit 34 receives the wire 12 from the wire transfer unit 90. Next, by driving the y-axis direction moving mechanism 33, the conveyance chuck portion 34 that has received the electric wire 12 from the electric wire conveyance portion 90 is positioned above the covering chuck portion 58. In this state, by driving the z-axis direction moving mechanism 36 and the chuck opening / closing drive unit, the electric wire 12 is transferred from the transfer chuck unit 34 to the covering chuck unit 58. At this time, the terminal 20 is supported by the support portion 68. Further, before this delivery operation, more specifically, immediately before the conveying chuck portion 34 is positioned above the covering chuck portion 58, the terminal pressing portion 61 is rotated so as to be temporarily located at a position where it does not interfere with delivery. Move. More specifically, after or during the delivery operation, the z-axis direction moving mechanism 36 is driven so that the sandwiching claw 58a of the covering chuck portion 58 is positioned at a position where the sandwiching claw 35a of the chuck portion 35 fits in the recess. Immediately after the chuck portion 35 is moved, the terminal 20 is rotated so as to return to a position where the terminal 20 can be pressed.
　被覆チャック部５８が被覆１４をチャックしたら、端子チャック部５４が端子２０をチャックする。ここでは、相手側接続部チャック部５５が相手側接続部２８をチャックすると共に、芯線圧着部２４チャック部が芯線圧着部２４をチャックする。なお、ここでは、相手側接続部チャック部５５が相手側接続部２８をチャックした後に、電線接続部チャック部５６が電線接続部２２をチャックするものとして説明するが、チャックする順番は上記とは逆であってもよいし、同時であってもよい。なお、端子チャック部５４は、端子用加熱部８４によって、端子２０をチャックする前に予め所定温度まで加熱されている。 When the covering chuck portion 58 chucks the covering 14, the terminal chuck portion 54 chucks the terminal 20. Here, the mating side connection portion chuck portion 55 chucks the mating side connection portion 28, and the core wire crimping portion 24 chuck portion chucks the core wire crimping portion 24. Here, it is described that the wire connection portion chuck portion 55 chucks the wire connection portion 22 after the counterpart connection portion chuck portion 55 chucks the counterpart connection portion 28. However, the order of chucking is as described above. The reverse may be sufficient, and simultaneous may be sufficient. The terminal chuck 54 is heated to a predetermined temperature by the terminal heating unit 84 before chucking the terminal 20.
　以上のように、電線１２が電線セット部５２にセットされたら次に、ステップＳ０２として、防食剤１８Ｂの供給位置を検出する。より詳細には、ここでは、図１２に示すように、ｙ軸方向移動機構３３を駆動することによって、撮像部３８を接続部分の上方に位置させた後、撮像部３８によって、接続部分を撮像する。そして、撮像部３８の撮像データから供給位置を検出する。例えば、端子２０に対する電線１２の圧着位置の寸法公差、又は電線セット部５２に対する電線１２のセット位置のばらつき公差に比べて、端子２０の形状における寸法公差は比較的小さいと考えられる。このため、例えば、得られた撮像データから端子２０の所定の位置を割り出し、割り出した所定位置を基準にして、定められた供給プログラムＰｒ１に従って防食剤１８Ｂを供給することで、比較的精度よく防食剤１８Ｂを供給可能となる。 As described above, when the electric wire 12 is set in the electric wire setting unit 52, the supply position of the anticorrosive 18B is detected as step S02. More specifically, here, as shown in FIG. 12, by driving the y-axis direction moving mechanism 33, the imaging unit 38 is positioned above the connection part, and then the connection part is imaged by the imaging unit 38. To do. Then, the supply position is detected from the imaging data of the imaging unit 38. For example, it is considered that the dimensional tolerance in the shape of the terminal 20 is relatively small as compared with the dimensional tolerance of the crimping position of the electric wire 12 with respect to the terminal 20 or the variation tolerance of the setting position of the electric wire 12 with respect to the electric wire set portion 52. For this reason, for example, the predetermined position of the terminal 20 is determined from the obtained imaging data, and the anticorrosion agent 18B is supplied in accordance with the predetermined supply program Pr1 with the determined predetermined position as a reference, so that the anticorrosion is relatively accurately performed. The agent 18B can be supplied.
　具体的には、ここでは、供給位置検出部１１７ｂが得られた撮像データから芯線圧着片２４ｂの延在方向縁部の位置を検出する。そして、当該縁部の位置を基準にして、図１３に示すように供給プログラムＰｒ１に従って防食剤１８Ｂを供給する。なお、図１３に示す例では、防食剤１８Ｂの滴が供給される予定位置が黒点によって示されている。 Specifically, here, the position of the edge portion in the extending direction of the core wire crimping piece 24b is detected from the imaging data obtained by the supply position detection unit 117b. And the anticorrosive 18B is supplied according to supply program Pr1, as shown in FIG. 13 on the basis of the position of the said edge part. In the example shown in FIG. 13, the planned positions where the drops of the anticorrosive agent 18 </ b> B are supplied are indicated by black dots.
　なお、防食剤１８Ｂを供給するに当たり、得られた撮像データから防食剤１８Ｂの供給範囲又は供給量などの条件を変更することも考えられる。図１４は、端子付電線１０に対する防食剤１８Ｂの供給位置の別の例を示す説明図である。 In supplying the anticorrosive 18B, it is also conceivable to change conditions such as the supply range or supply amount of the anticorrosive 18B from the obtained imaging data. FIG. 14 is an explanatory diagram illustrating another example of the supply position of the anticorrosive agent 18 </ b> B to the terminal-attached electric wire 10.
　具体的には、得られた撮像データから電線１２の延在方向に沿った被覆１４の縁部の位置を割り出す。そして、被覆１４の縁部の位置に応じて、図１３又は図１４に示すように防食剤１８Ｂの供給範囲を変更する。より詳細には図１３と図１４とを比べると、図１３に示す例では、被覆１４の縁部が端子２０に対して電線１２の延在方向に沿って後端側（ｙ軸方向に沿って負の側）に位置し、図１４に示す例では、被覆１４の縁部が端子２０に対して電線１２の延在方向に沿って先端側（ｙ軸方向に沿って正の側）に位置する。被覆１４の縁部の位置にこのような差がある場合でも、端子２０に対する被覆１４の縁部の位置にかかわらず被覆１４の縁部から後端側に所定距離離れた位置までしか防食剤１８Ｂを供給しないように設定すると、図１３及び図１４に示すように防食剤１８Ｂの供給される範囲が変わる。 Specifically, the position of the edge of the coating 14 along the extending direction of the electric wire 12 is determined from the obtained imaging data. And according to the position of the edge part of the coating | cover 14, as shown in FIG. 13 or FIG. 14, the supply range of the anticorrosive 18B is changed. More specifically, comparing FIG. 13 with FIG. 14, in the example shown in FIG. 13, the edge portion of the coating 14 is located along the extending direction of the electric wire 12 with respect to the terminal 20 along the rear end side (along the y-axis direction). In the example shown in FIG. 14, the edge portion of the coating 14 is on the distal end side (positive side along the y-axis direction) along the extending direction of the electric wire 12 with respect to the terminal 20. To position. Even when there is such a difference in the position of the edge of the coating 14, the anticorrosion agent 18 </ b> B only up to a position a predetermined distance away from the edge of the coating 14 to the rear end side regardless of the position of the edge of the coating 14 with respect to the terminal 20. If not set, the range in which the anticorrosive 18B is supplied changes as shown in FIGS.
　ここで、上記のように防食剤１８Ｂの供給範囲を変更する意図は、次の通りである。即ち、被覆１４は例えば、樹脂等を材料に構成されるため、金属を材料に構成される芯線１３及び端子２０に比べると熱伝導性に劣る。このため、被覆１４に供給される防食剤１８Ｂの範囲が広い場合、端子チャック部５４を介してその範囲に応じた被覆１４を加熱するのに時間がかかる。また、被覆１４の加熱が不十分である場合、防食剤１８Ｂが十分に広がらずに溜まってしまい、端子付電線１０の太さが太くなってしまう恐れがある。その一方で、防食性の観点から見ると、被覆１４の先端縁部から延在方向に沿って遠い位置まで防食剤１８Ｂを供給する必要性はそれほど高くない。従って、必要な防食性を持ち、且つ防食被膜１８が形成されたとしてもそれほど太くならない端子付電線１０をより短時間で得るために、端子２０に対する被覆１４の位置に応じて防食剤１８Ｂを供給する範囲を変更するものである。 Here, the intention of changing the supply range of the anticorrosive 18B as described above is as follows. That is, since the coating 14 is made of, for example, a resin or the like, it is inferior in thermal conductivity as compared with the core wire 13 and the terminal 20 that are made of a metal. For this reason, when the range of the anticorrosive agent 18 </ b> B supplied to the coating 14 is wide, it takes time to heat the coating 14 corresponding to the range via the terminal chuck portion 54. Moreover, when the coating 14 is not sufficiently heated, the anticorrosive 18B may not be sufficiently spread and collected, and the thickness of the terminal-attached electric wire 10 may be increased. On the other hand, from the viewpoint of the anticorrosive property, the necessity of supplying the anticorrosive agent 18B from the front edge of the coating 14 to a position far along the extending direction is not so high. Therefore, the anticorrosive 18B is supplied in accordance with the position of the coating 14 with respect to the terminal 20 in order to obtain the terminal-equipped electric wire 10 that has the necessary anticorrosion properties and does not become so thick even if the anticorrosion coating 18 is formed. The range to be changed is changed.
　なお、得られた撮像データから変更される防食剤１８Ｂの供給条件は上記されたものに限られない。 Note that the supply conditions of the anticorrosive 18B changed from the obtained imaging data are not limited to those described above.
　例えば、端子２０に対する被覆１４の縁部の位置が異なる場合でも、同じ量の防食剤１８Ｂを同じ位置に供給する場合には、端子用加熱部８４による加熱時間を変更することが考えられる。具体的には、被覆１４は、上述したように端子２０及び芯線１３に比べて熱伝導性に劣る。従って、防食剤１８Ｂの供給範囲における被覆１４の割合が大きい場合、端子用加熱部８４による加熱時間を長くし、反対に、防食剤１８Ｂの供給範囲における被覆１４の割合が小さい場合、端子用加熱部８４による加熱時間を短くすることが考えられる。これにより、被覆１４に供給された防食剤１８Ｂが、硬化する前に確実に所望の範囲に広がり易くなる。 For example, even when the position of the edge of the coating 14 with respect to the terminal 20 is different, when the same amount of the anticorrosive 18B is supplied to the same position, the heating time by the terminal heating unit 84 may be changed. Specifically, the coating 14 is inferior in thermal conductivity as compared with the terminal 20 and the core wire 13 as described above. Therefore, when the ratio of the coating 14 in the supply range of the anticorrosive 18B is large, the heating time by the terminal heating unit 84 is lengthened. Conversely, when the ratio of the coating 14 in the supply range of the anticorrosive 18B is small, the heating for the terminal is performed. It is conceivable to shorten the heating time by the part 84. Thereby, the anticorrosive agent 18B supplied to the coating 14 is surely easily spread to a desired range before being cured.
　また、例えば、端子２０に対する被覆１４の縁部の位置が異なる場合でも、防食剤１８Ｂを同じ位置に供給する場合には、被覆１４に供給される防食剤１８Ｂを少なくすることが考えられる。具体的には、被覆１４は、上述したように端子２０及び芯線１３に比べて熱伝導性に劣る。従って、防食剤１８Ｂの供給範囲における被覆１４の割合が大きい場合、被覆１４に供給する防食剤１８Ｂの一滴の量を少なくすることが考えられる。これにより、被覆１４に供給された防食剤１８Ｂが、硬化する前に確実に所望の範囲に広がり易くなる。この場合、防食剤１８Ｂの供給範囲における被覆１４の割合が大きい場合と小さい場合とでは、後者の場合の方が、端子付電線全体で見たときの防食剤１８Ｂの供給量が多くなると考えられる。 Further, for example, even when the position of the edge of the coating 14 with respect to the terminal 20 is different, when the anticorrosive 18B is supplied to the same position, the anticorrosive 18B supplied to the coating 14 can be reduced. Specifically, the coating 14 is inferior in thermal conductivity as compared with the terminal 20 and the core wire 13 as described above. Therefore, when the ratio of the coating 14 in the supply range of the anticorrosive 18B is large, it is conceivable to reduce the amount of one drop of the anticorrosive 18B supplied to the coating 14. Thereby, the anticorrosive agent 18B supplied to the coating 14 is surely easily spread to a desired range before being cured. In this case, in the case where the ratio of the coating 14 in the supply range of the anticorrosive 18B is large and the case where the ratio is small, it is considered that the supply amount of the anticorrosive 18B when viewed from the whole terminal-attached electric wire is increased. .
　また、図１５に示すように端子チャック部５４が端子２０をチャックしたら、次ステップＳ０３として、端子２０を昇温させる。ここでは、撮像部３８が接続部分を撮像している間を含めて、端子チャック部５４が端子２０をチャックした状態で所定時間経過させて、端子２０を加熱する。なお、端子２０の加熱時間、つまり、端子チャック部５４による端子２０のチャック時間は、実験的、経験的見地等に基づいて総合的に判断、決定される。 Further, as shown in FIG. 15, when the terminal chuck portion 54 chucks the terminal 20, the temperature of the terminal 20 is raised as the next step S03. Here, the terminal 20 is heated for a predetermined period of time with the terminal chuck 54 chucking the terminal 20 including the time when the imaging unit 38 images the connection portion. The heating time of the terminal 20, that is, the chucking time of the terminal 20 by the terminal chuck portion 54 is comprehensively determined and determined based on experimental and empirical viewpoints.
　端子２０が十分に昇温したら、次ステップＳ０４として、防食剤１８Ｂを供給する。より詳細には、図１６に示すようにｙ軸方向移動機構３３を駆動して供給部４０を接続部分の上方に位置させる。この際、ステップＳ０２で検出された供給位置に応じた位置に供給部４０を位置させるとよい。そして、吐出機構４１によって防食剤１８Ｂを吐出し、接続部分に供給する。この際、吐出機構移動機構４６を駆動させて、防食剤１８Ｂを一滴ずつ予め設定された位置、ここでは、図１３において黒点で示される位置に供給する。この際、吐出機構４１は、吐出機構移動機構４６を駆動することによってＱ１、Ｑ２、Ｑ３の各部において、例えば、図１３において黒点を結ぶ線に応じた軌跡に沿って移動する。図１３に示される例では、ｘ軸方向に沿って一端側から他端側に移動しつつこの方向に沿った吐出位置に防食剤１８Ｂを吐出した後、ｙ軸方向に移動し、ｘ軸方向に沿って他端側から一端側に移動しつつこの方向に沿った吐出位置に防食剤１８Ｂを吐出するものである。もっとも、吐出機構移動機構４６による吐出機構４１の移動は上記に限られない。例えば、ｘ軸方向に沿って一端側から他端側に向けて移動する際中にｙ軸方向に沿って移動するものであってもよいし、常にｘ軸方向に沿って一端側から他端側に向けて移動するものであってもよい。 When the terminal 20 is sufficiently heated, the anticorrosive 18B is supplied as the next step S04. More specifically, as shown in FIG. 16, the y-axis direction moving mechanism 33 is driven to position the supply unit 40 above the connection portion. At this time, the supply unit 40 may be positioned at a position corresponding to the supply position detected in step S02. And the anticorrosive 18B is discharged by the discharge mechanism 41, and is supplied to a connection part. At this time, the discharge mechanism moving mechanism 46 is driven to supply the anticorrosive 18B drop by drop to a preset position, here a position indicated by a black dot in FIG. At this time, the discharge mechanism 41 is moved along the locus corresponding to the line connecting the black dots in FIG. 13, for example, in each part of Q1, Q2, and Q3 by driving the discharge mechanism moving mechanism 46. In the example shown in FIG. 13, the anticorrosive 18 </ b> B is discharged to the discharge position along this direction while moving from one end side to the other end side along the x-axis direction, and then moved in the y-axis direction. The anticorrosive 18B is discharged to the discharge position along this direction while moving from the other end side to the one end side along the direction. However, the movement of the discharge mechanism 41 by the discharge mechanism moving mechanism 46 is not limited to the above. For example, it may move along the y-axis direction while moving from one end side to the other end side along the x-axis direction, or always move from one end side to the other end along the x-axis direction. You may move toward the side.
　ここで、防食剤１８Ｂの供給が開始される前に、電線接続部チャック部５６は、図１７に示すように開かれて、接続部分をチャックした状態が解消される。これにより、電線接続部チャック部５６が供給作業の邪魔になること、及び電線接続部２２の周囲に供給された防食剤１８Ｂが電線接続部チャック部５６に付着することが抑制される。また、相手側接続部チャック部５５は、防食剤１８Ｂの供給中も相手側接続部２８をチャックした状態を維持する。これにより、経時変化及び防食剤１８Ｂが供給されることなどに起因して端子２０の温度が下がる度合いが小さくなり、もって供給された防食剤１８Ｂが広がりにくくなることが抑制される。 Here, before the supply of the anticorrosive 18B is started, the wire connection portion chuck portion 56 is opened as shown in FIG. 17, and the state where the connection portion is chucked is eliminated. Thereby, it is suppressed that the electric wire connection part chuck | zipper part 56 obstructs supply operation | work, and that the anticorrosive 18B supplied to the circumference | surroundings of the electric wire connection part 22 adheres to the electric wire connection part chuck | zipper part 56. Further, the mating connector chuck 55 maintains the chucked mating connector 28 during the supply of the anticorrosive 18B. As a result, the degree of temperature drop of the terminal 20 due to changes over time and the supply of the anticorrosive agent 18B is reduced, and the supplied anticorrosive agent 18B is less likely to spread.
　防食剤１８Ｂの供給が終了したら、次ステップＳ０５として、供給状態を検査する。ここでは、防食剤１８Ｂの供給時に各滴を、検知部１００によって検知している。従って、検知部１００の検知結果と、供給位置検出部１１７ｂの検出出力とに基づいて、供給位置をマッピングする。そして、当該マップを、合格判定基準Ｍと比較することで、所定の位置に防食剤１８Ｂの粒が供給されたかを判定する。検査結果は、例えば、表示部１１９に表示されることが考えられる。 When the supply of the anticorrosive 18B is completed, the supply state is inspected as the next step S05. Here, each drop is detected by the detection unit 100 when the anticorrosive 18B is supplied. Therefore, the supply position is mapped based on the detection result of the detection unit 100 and the detection output of the supply position detection unit 117b. Then, by comparing the map with the acceptance criterion M, it is determined whether or not the particles of the anticorrosive 18B are supplied to a predetermined position. For example, the inspection result may be displayed on the display unit 119.
　より詳細には、合格判定基準Ｍとしては、図１３において黒点で示される供給予定位置を利用することが考えられる。すなわち、図１３において黒点で示される供給予定位置は、端子２０における基準位置に対して、点状の防食剤１８Ｂを供給する理想の位置を示している。従って、この理想の位置に公差を付した分を合格判定基準Ｍとすることができる。一方検知部１００での検知結果を、吐出機構移動機構４６の移動動作と対応付けたデータを作成し、当該データをさらに供給位置検出部１１７ｂの検出出力に対応させることで、端子２０において、点状の防食剤１８Ｂが基準位置に対してどこに滴下されたかのデータを得ることができる。これを上記合格判定基準Ｍと比較することで、実際の点状の防食剤１８Ｂの滴下位置が、理想位置に公差を付した範囲内に収まっているかどうかを判定できる。そして、この判定結果から供給状態の合否を判定することができる。例えば、全ての防食剤１８Ｂの粒がそれぞれ上記範囲内に収まっている場合に合格と判定し、一つでも上記範囲内に収まっていない場合に不合格と判定するなどの態様が考えられる。 More specifically, as the acceptance criterion M, it is conceivable to use a planned supply position indicated by a black dot in FIG. That is, the planned supply position indicated by a black dot in FIG. 13 indicates an ideal position for supplying the point-like anticorrosive 18 </ b> B with respect to the reference position at the terminal 20. Therefore, the acceptance criterion M can be obtained by adding a tolerance to the ideal position. On the other hand, by creating data in which the detection result of the detection unit 100 is associated with the movement operation of the discharge mechanism moving mechanism 46, and by further making the data correspond to the detection output of the supply position detection unit 117b, It is possible to obtain data of where the anticorrosive 18B in the shape is dropped with respect to the reference position. By comparing this with the acceptance criterion M, it is possible to determine whether or not the actual dropping position of the point-like anticorrosive 18B is within a range in which a tolerance is added to the ideal position. And the pass / fail of the supply state can be determined from this determination result. For example, it can be determined that the particles of all the anticorrosives 18B are determined to be acceptable when the particles are within the above range, and the particles are determined to be unacceptable when even one of the particles is not within the above range.
　なお、供給状態の検査としては、上記検知部１００による検査のほかに画像検査を行ってもよい。この場合、図１８に示すようにｙ軸移動機構を駆動させて撮像部３８を接続部分の上方に位置させた状態で、撮像部３８によって接続部分を撮像する。そして得られた撮像データから防食剤１８Ｂの供給状態を検査する。 In addition, as an inspection of the supply state, an image inspection may be performed in addition to the inspection by the detection unit 100. In this case, as illustrated in FIG. 18, the connection portion is imaged by the imaging unit 38 in a state where the y-axis moving mechanism is driven and the imaging unit 38 is positioned above the connection portion. And the supply state of anticorrosive 18B is test | inspected from the acquired imaging data.
　供給状態の検査が終了したら、次ステップＳ０６として、防食剤１８Ｂの余剰分を吸引する。ここでは、まず図１９に示すように被覆押え片移動機構６６を駆動させて被覆押え片６５によって被覆１４を押える。そして、吸引部移動機構を駆動させて吸引部７２を電線接続部２２に接近させる。この際ここでは、図１８に示すように吸引用当接部７７を電線接続部２２の下面に当接させる。この後、吸引駆動部７５を駆動させて接続部分に存在する防食剤１８Ｂの余剰分を吸引する。もっとも、当該ステップＳ０６は、供給が終了した後であれば、供給状態の検査前または検査と並行して行われてもよい。 When the inspection of the supply state is completed, the surplus of the anticorrosive 18B is sucked as the next step S06. Here, first, as shown in FIG. 19, the covering presser piece moving mechanism 66 is driven and the covering 14 is pressed by the covering presser piece 65. Then, the suction part moving mechanism is driven to bring the suction part 72 closer to the wire connection part 22. Here, as shown in FIG. 18, the suction contact portion 77 is brought into contact with the lower surface of the wire connection portion 22. Then, the suction drive part 75 is driven and the excess part of the anticorrosive 18B which exists in a connection part is attracted | sucked. However, the step S06 may be performed before the supply state inspection or in parallel with the inspection as long as the supply is completed.
　なお、供給状態の検査の後に当該ステップＳ０６が行われる場合、不合格と判定された端子付電線に付いては、当該ステップＳ０６は行われなくてもよい。 In addition, when the said step S06 is performed after an inspection of a supply state, the said step S06 does not need to be performed about the electric wire with a terminal determined to be unacceptable.
　余剰分の吸引が終了したら、次ステップＳ０７として、電線セット部５２から電線１２を排出する。より詳細には、被覆押え片６５、吸引部７２を退避させると共に、相手側接続部チャック部５５を開く。そして、ｙ軸方向移動機構３３を駆動させて搬送用チャック部３４を被覆チャック部５８の上方に位置させる。この状態でｚ軸方向移動機構３６、チャック開閉用の駆動部を駆動させて、被覆チャック部５８から搬送用チャック部３４に電線１２を受け渡す。この受渡動作の前後で、ステップＳ０１のときと同様に受渡動作の邪魔にならないように端子押え部６１も回動する。 When the suction for the surplus is completed, the electric wire 12 is discharged from the electric wire setting unit 52 as the next step S07. More specifically, the covering presser piece 65 and the suction part 72 are retracted, and the mating connection part chuck part 55 is opened. Then, the y-axis direction moving mechanism 33 is driven to position the transport chuck portion 34 above the covering chuck portion 58. In this state, the z-axis direction moving mechanism 36 and the chuck opening / closing drive unit are driven to deliver the electric wire 12 from the covering chuck unit 58 to the conveying chuck unit 34. Before and after this delivery operation, the terminal presser 61 also rotates so as not to obstruct the delivery operation, as in step S01.
　搬送用チャック部３４が電線１２を受け取ったら、ｙ軸移動機構を駆動させて搬送用チャック部３４をセットバー９３の支持爪９３ｂの上方に位置させる。この状態で、ｚ軸方向移動機構３６、チャック開閉用の駆動部を駆動させて、搬送用チャック部３４から支持爪９３ｂに電線１２を受け渡す。これにより、電線セット部５２から電線搬送部９０に電線１２が排出された状態となる。 When the transport chuck portion 34 receives the electric wire 12, the y-axis moving mechanism is driven to position the transport chuck portion 34 above the support claw 93 b of the set bar 93. In this state, the z-axis direction moving mechanism 36 and the chuck opening / closing drive unit are driven to deliver the electric wire 12 from the transfer chuck unit 34 to the support claw 93b. Thereby, it will be in the state where the electric wire 12 was discharged | emitted from the electric wire set part 52 to the electric wire conveyance part 90. FIG.
　なお、ステップＳ０５で不合格と判定された端子付電線１０については、電線搬送部９０の元の位置に戻さずに、別途設けられた不良品排出部に排出されることもあり得る。 Note that the terminal-attached electric wire 10 determined to be unacceptable in step S05 may be discharged to a separately provided defective product discharge unit without returning to the original position of the electric wire transport unit 90.
　電線セット部５２から電線搬送部９０に電線１２が排出されたら次ステップＳ０８として、電線搬送部９０の電線１２を送る。例えば、隣り合う二対の支持爪９３ｂの間隔分セットバー９３を送る。これにより、次の加工対象の電線１２が搬送用チャック部３４でチャック可能な位置に供給される。 When the electric wire 12 is discharged from the electric wire setting unit 52 to the electric wire conveyance unit 90, the electric wire 12 of the electric wire conveyance unit 90 is sent as the next step S08. For example, the set bar 93 is sent by an interval between two adjacent pairs of support claws 93b. As a result, the next electric wire 12 to be processed is supplied to a position where it can be chucked by the conveyance chuck portion 34.
　後は、ステップＳ０１に戻り、ステップＳ０１乃至ステップＳ０８を繰り返すことによって、セットバー９３に支持された複数の端子付電線１０に順次防食剤１８Ｂが供給されて、防食被膜１８が形成された端子付電線１０が連続的に製造される。なお、ここでは、接続部分に供給された防食剤１８Ｂは、自然冷却されることによって粘性が高まり、もって防食被膜１８を形成する。もっとも、接続部分に供給された防食剤１８Ｂは、空冷又は水冷などの冷却手段によって冷却されるものであってもよい。この場合、当該冷却手段が防食剤供給装置３０に組み込まれていてもよいし、組み込まれていなくてもよい。 Thereafter, returning to step S01, by repeating steps S01 to S08, the anticorrosive agent 18B is sequentially supplied to the plurality of electric wires with terminals 10 supported by the set bar 93, and the anticorrosive coating 18 is formed. The electric wire 10 is manufactured continuously. Here, the anticorrosive agent 18 </ b> B supplied to the connection portion is naturally cooled to increase the viscosity, thereby forming the anticorrosion coating 18. But the anticorrosive 18B supplied to the connection part may be cooled by cooling means, such as air cooling or water cooling. In this case, the cooling means may or may not be incorporated in the anticorrosive supply device 30.
　なお、防食被膜１８が形成された端子付電線１０を防食剤供給装置３０から排出する作業、及び、防食剤１８Ｂが供給されていない端子付電線１０を防食剤供給装置３０に供給する作業は、防食剤１８Ｂの供給作業中に併せて行われてもよいし、セットバー９３に支持されたすべての端子付電線１０に防食剤１８Ｂを供給した後に一括して行われてもよい。 In addition, the operation | work which discharges the electric wire 10 with a terminal in which the anticorrosion coating 18 was formed from the anticorrosive agent supply apparatus 30, and the operation | work which supplies the electric wire with a terminal 10 to which the anticorrosive agent 18B is not supplied to the anticorrosive agent supply apparatus 30 are The anticorrosive agent 18B may be supplied during the supply operation, or may be performed collectively after supplying the anticorrosive agent 18B to all the electric wires with terminals 10 supported by the set bar 93.
　以上のように構成された防食剤供給状態検査装置及びこれを備える防食剤供給装置３０によると、供給部４０から滴下された防食剤１８Ｂの粒を検知することによって、防食剤１８Ｂが必要量滴下されたことを確認することができる。これにより、端子付電線１０における電線１２と端子２０との接続部分に防食剤１８Ｂを供給した際に、供給状態の検査結果の信頼性を向上させることができる。 According to the anticorrosive agent supply state inspection device configured as described above and the anticorrosive agent supply device 30 including the anticorrosive agent supply state inspection device, the necessary amount of the anticorrosive agent 18B is dropped by detecting the particles of the anticorrosive agent 18B dropped from the supply unit 40. Can be confirmed. Thereby, when the anticorrosion agent 18B is supplied to the connection part of the electric wire 12 and the terminal 20 in the electric wire 10 with a terminal, the reliability of the inspection result of a supply state can be improved.
　また、検知部１００は、供給部４０から滴下された後、接続部分に付着するまでの間の防食剤１８Ｂの粒を検知するため、防食剤１８Ｂをより確実に一滴ずつ検知可能となる。 Moreover, since the detection part 100 detects the particle | grains of the anticorrosive 18B after dripping from the supply part 40 until it adheres to a connection part, it becomes possible to detect the anticorrosive 18B more reliably drop by drop.
　また、判定部１１７ｄは、検知部１００からの検出出力に加えて、供給位置検出部１１７ｂの検出出力に基づいて防食剤１８Ｂの供給状態の合否を判定するため、所望の供給位置に防食剤１８Ｂが滴下されたかどうかを判定することができ、供給状態の検査結果の信頼性を向上させることができる。 In addition to the detection output from the detection unit 100, the determination unit 117d determines whether or not the supply state of the anticorrosive 18B is acceptable based on the detection output of the supply position detection unit 117b. It is possible to determine whether or not the liquid has been dripped, and the reliability of the inspection result of the supply state can be improved.
　また、検知部１００からの検出出力に加えて合格判定基準Ｍに基づいて、防食剤１８Ｂが必要量滴下されたことかを判定する。これにより、端子付電線１０における電線１２と端子２０との接続部分に防食剤１８Ｂを供給した際に、供給状態の検査結果の信頼性を向上させることができる。 In addition to the detection output from the detection unit 100, based on the acceptance criterion M, it is determined whether the necessary amount of the anticorrosive 18B has been dropped. Thereby, when the anticorrosion agent 18B is supplied to the connection part of the electric wire 12 and the terminal 20 in the electric wire 10 with a terminal, the reliability of the inspection result of a supply state can be improved.
　｛変形例｝
　図２０は、変形例に係る防食剤供給装置１３０を示す概略平面図である。変形例に係る防食剤供給装置１３０では、１つの電線搬送部９０に対して、第１機構３２及び第２機構５０を有する加工部１３１が２つ設けられている。このように、１つの電線搬送部９０に対して複数の加工部１３１が設けられることにより、１つの防食剤供給装置１３０における生産効率を向上させることができる。なお、１つの電線搬送部９０に対して２つの加工部１３１が設けられる場合、電線搬送部９０による電線１２の送り方としては例えば、以下の２通りが考えられる。１つ目は、２つの加工部１３１で加工される端子付電線１０が電線搬送部９０の搬送方向に沿って交互に並べられる場合である。この場合、１回の送りで隣り合う支持爪９３ｂの間隔の２倍の寸法分、セットバー９３を送るとよい。２つ目は、電線搬送部９０の搬送方向に沿った一方側に一方の加工部１３１の加工対象となる端子付電線１０がまとめられると共に電線搬送部９０の搬送方向に沿った他方側に他方の加工部１３１の加工対象となる端子付電線１０がまとめられる場合である。この場合は、実施形態と同様に、１回の送りで隣り合う対の支持爪９３ｂの間隔の寸法分、セットバー９３を送るとよい。 {Modification}
FIG. 20 is a schematic plan view showing an anticorrosive agent supply apparatus 130 according to a modification. In the anticorrosive agent supply apparatus 130 according to the modification, two processing units 131 having the first mechanism 32 and the second mechanism 50 are provided for one electric wire transport unit 90. Thus, by providing the some process part 131 with respect to the one electric wire conveyance part 90, the production efficiency in the one anticorrosive agent supply apparatus 130 can be improved. In addition, when the two process parts 131 are provided with respect to one electric wire conveyance part 90, as the method of sending the electric wire 12 by the electric wire conveyance part 90, the following two types can be considered, for example. The first case is a case where the terminal-attached electric wires 10 processed by the two processing units 131 are alternately arranged along the conveyance direction of the electric wire conveyance unit 90. In this case, the set bar 93 may be fed by a size twice as large as the interval between the adjacent support claws 93b in one feed. Secondly, the terminal-attached electric wires 10 to be processed by one processing unit 131 are collected on one side along the conveyance direction of the electric wire conveyance unit 90 and the other side along the conveyance direction of the electric wire conveyance unit 90 is the other. This is a case where the terminal-attached electric wires 10 to be processed by the processed portion 131 are collected. In this case, as in the embodiment, the set bar 93 may be fed by the size of the interval between the pair of adjacent support claws 93b in one feed.
　また、実施形態において、防食剤１８Ｂが、車両使用環境下の温度で粘性を有すると共に加熱により粘度が低下する部材であるものとして説明したが、このことは必須ではない。例えば、防食剤１８Ｂは、一滴ずつ供給可能なものであれば、熱可塑性樹脂を含むもの、熱硬化性樹脂を含むもの、光硬化性樹脂を含むもの、又はこれらを組み合わせたものであってもよい。この場合でも、上記防食剤供給状態検査装置によって供給状態の検査を行うことができる。 In the embodiment, the anticorrosive 18B has been described as a member that has viscosity at a temperature in a vehicle use environment and decreases in viscosity by heating, but this is not essential. For example, the anticorrosive 18B may be one containing a thermoplastic resin, one containing a thermosetting resin, one containing a photocurable resin, or a combination thereof, as long as it can be supplied drop by drop. Good. Even in this case, the supply state can be inspected by the anticorrosive agent supply state inspection device.
　また、実施形態において、検知部１００は、供給部４０から滴下された後、接続部分に付着するまでの間の防食剤１８Ｂの粒を検知するものとして説明したが、このことは必須ではない。検知部は、供給部４０から滴下される前、つまり、吐出口から出てきて粒状になった防食剤１８Ｂを検出するものであってもよい。また、検知部は、接続部分に付着した後の防食剤１８Ｂの粒を検知するものであってもよい。 Further, in the embodiment, the detection unit 100 has been described as detecting the particles of the anticorrosive 18B from when dropped from the supply unit 40 until the detection unit 100 adheres to the connection portion, but this is not essential. The detection unit may detect the anticorrosive 18B that has come out of the supply unit 40, that is, has come out of the discharge port and has become granular. Moreover, a detection part may detect the particle | grains of the anticorrosive 18B after adhering to a connection part.
　また、実施形態において、検知部１００による供給状態の検査として、実際に滴下された防食剤１８Ｂのすべての粒の位置を、理想の供給位置と比較することで行うものとして説明したが、このことは必須ではない。例えば、検知部１００が実際に滴下された防食剤１８Ｂの粒の数を検知することによって、供給状態の検査を行うものであってもよい。この場合、例えば、実際に滴下された防食剤１８Ｂの粒の数を理想の供給粒数と比較することによって、供給状態の検査を行うことが考えられる。また、実際に滴下された防食剤１８Ｂの粒の一部の位置を、理想の供給位置と比較することで供給状態の検査を行うことも考えられる。この場合、例えば、実際に最初に滴下される防食剤１８Ｂの粒の位置（ここでは、基端側部分Ｑ１に最初に滴下される位置）を理想の供給位置と比較することで供給状態の検査を行うものであってもよいし、最後に滴下される防食剤１８Ｂの粒の位置（ここでは、先端側部分Ｑ３に最後に滴下される位置）を理想の供給位置と比較することで供給状態の検査を行うものであってもよい。また、各部分Ｑ１、Ｑ２、Ｑ３に滴下される防食剤１８Ｂの粒の一部の位置を理想の供給位置と比較することで供給状態の検査を行うものであってもよい。 In the embodiment, the inspection of the supply state by the detection unit 100 has been described as being performed by comparing the positions of all the particles of the anticorrosive 18B actually dropped with the ideal supply position. Is not required. For example, the supply state may be inspected by detecting the number of particles of the anticorrosive agent 18B actually dropped by the detection unit 100. In this case, for example, it is conceivable to inspect the supply state by comparing the number of particles of the anticorrosive 18B actually dropped with the ideal number of supply particles. It is also conceivable to check the supply state by comparing the position of a part of the particles of the anticorrosive 18B actually dropped with the ideal supply position. In this case, for example, the inspection of the supply state is performed by comparing the position of the particle of the anticorrosive 18B actually dropped first (here, the position first dropped on the base end portion Q1) with the ideal supply position. Or the supply state by comparing the position of the particles of the anticorrosive 18B dripped last (here, the position finally dripped onto the tip side portion Q3) with the ideal supply position. The inspection may be performed. Moreover, you may test | inspect a supply state by comparing the position of the part of the particle | grains of the anticorrosive 18B dripped at each part Q1, Q2, Q3 with an ideal supply position.
　また、実施形態において、制御部１１０は、合格判定基準Ｍを記憶する記憶部１１５をさらに含み、判定部１１７ｄは、検知部１００からの検出出力に加えて合格判定基準Ｍに基づいて防食剤１８Ｂの供給状態の合格判定を行うものとして説明したが、このことは必須ではない。例えば、制御部１１０は、端子付電線１０ごとに撮像データから被覆１４の縁部の位置に応じた合格判定基準を作成し、これに基づいて防食剤１８Ｂの供給状態の合格判定を行うものであってもよい。 Moreover, in embodiment, the control part 110 further contains the memory | storage part 115 which memorize | stores the acceptance criterion M, and the determination part 117d is anticorrosive 18B based on the acceptance criterion M in addition to the detection output from the detection part 100. However, this is not essential. For example, the control unit 110 creates a pass determination criterion corresponding to the position of the edge of the covering 14 from the imaging data for each terminal-attached electric wire 10, and performs a pass determination of the supply state of the anticorrosive 18B based on this. There may be.
　また、実施形態において、検知部１００の検知結果および合格判定基準Ｍをマップ状にしてこれを比較するものとして説明したが、このことは必須ではない。例えば、実際に滴下された防食剤１８Ｂの位置および理想の供給位置に対して、それぞれ端子２０における基準位置からの距離を数値化し、これを比較することで供給状態の検査を行うものであってもよい。つまり、実際に滴下された防食剤１８Ｂの理想の供給位置に対するばらつきを算出し、これに基づいて供給状態の検査を行うものであってもよい。 In the embodiment, the detection result of the detection unit 100 and the acceptance criterion M are described as being mapped and compared, but this is not essential. For example, the distance from the reference position in the terminal 20 is converted into a numerical value with respect to the position of the anticorrosive 18B actually dropped and the ideal supply position, and the supply state is inspected by comparing the values. Also good. That is, the dispersion | variation with respect to the ideal supply position of the anticorrosive 18B actually dripped may be calculated, and a supply state test | inspection may be performed based on this.
　なお、上記実施形態及び各変形例で説明した各構成は、相互に矛盾しない限り適宜組み合わせることができる。 In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.
　以上のようにこの発明は詳細に説明されたが、上記した説明は、すべての局面において、例示であって、この発明がそれに限定されるものではない。例示されていない無数の変形例が、この発明の範囲から外れることなく想定され得るものと解される。 Although the present invention has been described in detail as described above, the above description is illustrative in all aspects, and the present invention is not limited thereto.
