Description
本発明は、電気メッキ装置に係り、より詳しくは、鋼板のエッジ部の過メッキを防止するための電気メッキ装置に関する。 The present invention relates to an electroplating apparatus, and more particularly to an electroplating apparatus for preventing overplating of an edge portion of a steel plate.
一般的に、自動車用鋼板や電気製品の外装材などに使用される鋼板は、焼鈍工程を経た後、使用目的に要求される耐食性を持たせるために電気亜鉛メッキ工程を経る。
一般的に、電気メッキを施すときにメッキ電流が鋼板のエッジ部位に集中する現象により、その部位のメッキ付着量が他の部位に比べて多くなるか、デンドライト（ｄｅｎｄｒｉｔｅ）形態の亜鉛成長が起こってメッキ欠陥を誘発するなどの問題が発生する。不溶性陽極を使用するメッキ設備では、鋼板の幅を超える部位では陽極が向かい合う形となり、様々な原因によりその部位の陽極間には電位差が発生して陽極表面の酸化イリジウム皮膜が破壊される問題が発生し、陽極の寿命が短縮される現象が現れる。
In general, steel plates used for automobile steel plates, exterior materials for electrical products, and the like are subjected to an electrogalvanizing step in order to provide corrosion resistance required for the purpose of use after an annealing step.
Generally, when electroplating, the plating current concentrates on the edge part of the steel plate, so that the amount of plating attached to that part is larger than other parts, or dendritic zinc growth occurs. This causes problems such as inducing plating defects. In plating equipment that uses insoluble anodes, the anodes face each other at the part that exceeds the width of the steel sheet, and due to various reasons, a potential difference occurs between the anodes at that part and the iridium oxide film on the anode surface is destroyed. The phenomenon that occurs and the life of the anode is shortened appears.
これをより詳しく説明すると、連続して鋼板に電気亜鉛メッキを施す際に、電気の特性上、鋼板のエッジ部位に電流が集中する現象が現れ、これにより次の２つの問題が発生する。 This will be described in more detail. When electrogalvanizing is continuously performed on a steel plate, a phenomenon in which current concentrates on the edge portion of the steel plate appears due to the electrical characteristics, which causes the following two problems.
第一に、エッジ部位のメッキ付着量が他の部位に比べて増加するエッジの過メッキ問題が発生する。このようなエッジの過メッキは、メッキを施した後、コイル状に巻き取る過程で、エッジ部の過多なメッキ付着により鋼板に屈曲を誘発するから、コイルを小さな単位で製作するしかないため、運送費や生産性に多くの問題を引き起こしてきた。 First, an edge overplating problem occurs in which the amount of plating attached to the edge portion increases as compared with other portions. Such edge overplating is the process of winding in the form of a coil after plating, inducing bending in the steel sheet due to excessive plating adhesion of the edge part, so there is no choice but to manufacture the coil in small units, It has caused many problems in transportation costs and productivity.
第二に、エッジ部位に発生するデンドライト形態の亜鉛付着問題である。このような形態で付着した亜鉛は非常によく剥がれるため、ロールなどを始めとするメッキ設備に付着してメッキ鋼板の表面に跡形の不良を誘発する問題が発生し、特に伝導ロールに付着する場合、付着した亜鉛粉を中心に伝導ロールに亜鉛がメッキされる現象に起因する亜鉛ピックアップ現象をもたらし、生産に多くの問題を引き起こす。 Secondly, there is a problem of zinc adhesion in the form of dendrites generated at the edge part. Zinc adhering in this form peels off very well, causing problems such as adhesion to plating equipment such as rolls and the like, causing trace defects on the surface of plated steel sheets, especially when adhering to conductive rolls The zinc pick-up phenomenon is caused by the phenomenon that zinc is plated on the conductive roll around the adhered zinc powder, and causes many problems in production.
このような問題を解決するために、従来は、図１のような形態のエッジマスクを適用してきた。図１に示すように、陰極（ｃａｔｈｏｄｅ）の役割を果たす鋼板１を中心に一定距離離隔して上部陽極（ａｎｏｄｅ）２および下部陽極（ａｎｏｄｅ）３が位置し、鋼板１の両端、すなわちエッジ部の電流集中を遮断するためのエッジマスク（ｅｄｇｅ ｍａｓｋ）４を適用してきた。 In order to solve such a problem, an edge mask having a form as shown in FIG. 1 has conventionally been applied. As shown in FIG. 1, an upper anode 2 and a lower anode 3 are located at a certain distance from a steel plate 1 serving as a cathode, and both ends of the steel plate 1, that is, edge portions. An edge mask 4 has been applied to block current concentration.
ところが、エッジ部の電流を遮断するためには鋼板のエッジ部位に正確にエッジマスクを接近させる必要が生じるが、実際鋼板に電気メッキを施す設備では鋼板が幅方向に左右に移動する蛇行現象が発生するため、鋼板とエッジマスク間の間隔が１０ｍｍ以下の近接が難しく、これによりエッジ部の過メッキによる電流密度の減少に限界を持っていた。
また、鋼板のエッジ部の電流密度の減少はラインの生産性に直結するが、特に、後メッキ（片面５５ｇ／ｍ２）作業の際に印加される電流密度が増加するにつれて、エッジ部の電流密度の集中現象はさらに増加する。このようなエッジ部の電流密度の増加は、後メッキラインの作業速度に制限されるため、生産性が急激に低下するという問題がある。
However, in order to cut off the current at the edge part, it is necessary to bring the edge mask close to the edge part of the steel plate accurately. However, in actual equipment for electroplating the steel plate, the meandering phenomenon in which the steel plate moves left and right in the width direction is caused. Therefore, it is difficult for the distance between the steel plate and the edge mask to approach 10 mm or less, which limits the reduction in current density due to overplating of the edge portion.
In addition, the decrease in the current density at the edge of the steel sheet is directly linked to the productivity of the line. In particular, as the current density applied during post-plating (single side 55 g / m 2 ) increases, the current at the edge is increased. The density concentration phenomenon further increases. Such an increase in the current density at the edge portion is limited by the working speed of the post-plating line, so that there is a problem that productivity is rapidly reduced.
本発明は、このような問題点を解決するために案出されたもので、その目的は、鋼板のエッジ部における電流密度の減少のために、既存の陰極エッジマスクに陽極エッジマスクを追加することにより、鋼板のエッジ部の過メッキを防止することができる電気メッキ装置を提供することにある。 The present invention has been devised to solve such problems, and the object is to add an anode edge mask to an existing cathode edge mask in order to reduce the current density at the edge of the steel plate. Accordingly, an object of the present invention is to provide an electroplating apparatus capable of preventing overplating of the edge portion of a steel plate.
上記目的を達成するために、本発明の一実施形態に係るエッジ部の過メッキを防止するための電気メッキ装置は、鋼板を中心に一定距離離隔して設けられた陽極の間でメッキを施す鋼板の電気メッキ装置において、前記鋼板のエッジ部に近接して設けられ、前記エッジ部と前記陽極との通電を遮断する陰極エッジマスクと、前記陰極エッジマスクの上下部にそれぞれ離隔して設けられ、前記エッジ部と前記陽極との通電を遮断する陽極エッジマスクとを含むことを特徴とする。 In order to achieve the above object, an electroplating apparatus for preventing overplating of an edge according to an embodiment of the present invention performs plating between anodes provided at a predetermined distance from a center of a steel plate. In the steel plate electroplating apparatus, the cathode edge mask provided close to the edge portion of the steel plate, which cuts off the energization between the edge portion and the anode, and provided separately above and below the cathode edge mask. And an anode edge mask for cutting off the energization between the edge portion and the anode.

The anode edge mask can increase or decrease an area for cutting off the energization between the edge portion and the anode.
A support portion connected to one side surface of the cathode edge mask; a connection portion extending in a vertical direction of the support portion; and connected to the support portion and the anode edge mask; and connected to one end of the support portion. It may further include a mask driving unit that moves the cathode edge mask forward and backward, and a position adjusting hole that is provided in the anode edge mask in the direction of the steel plate and is coupled to the connecting unit.
前記陰極エッジマスクは、鋼板が接する面に、内部に鋼板が通過し得るように設けられる溝を有してもよい。

The cathode edge mask and the anode edge mask can each be formed of a nonconductor.
The anode edge mask may be formed of a conductive material, and may have a nonconductive layer on a surface facing the anode.
本発明に係るエッジ部の過メッキを防止するための電気メッキ装置によれば、鋼板の蛇行によって陰極エッジマスクが鋼板のエッジ部に近接しない場合でも、陽極エッジマスクによって、鋼板のエッジ部に集中する電流密度を減少させることができるため、電気メッキ時のエッジ部の電流集中による過メッキ現象およびデンドライト形態の析出による不良および操業問題を解決することができる。また、亜鉛片面メッキ量５５ｇ／ｍ２以上への後メッキ作業の際にもラインの稼働速度を７０〜１００ｍｐｍ以上に増加させることにより、生産性を大幅に向上させることができる。 According to the electroplating apparatus for preventing overplating of the edge portion according to the present invention, even when the cathode edge mask is not close to the edge portion of the steel plate due to meandering of the steel plate, the anode edge mask concentrates on the edge portion of the steel plate. Therefore, the overplating phenomenon due to the current concentration at the edge portion during electroplating and defects due to the deposition of dendrite and operation problems can be solved. Moreover, productivity can be significantly improved by increasing the line operating speed to 70 to 100 mpm or more during post-plating work to a zinc single-side plating amount of 55 g / m 2 or more.

以下、添付図面を参照して、本発明の好適な実施形態に係るエッジ部の過メッキを防止するための電気メッキ装置について説明する。 Hereinafter, an electroplating apparatus for preventing edge overplating according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.
従来は、陰極エッジマスクを鋼板のエッジ部に近接させ、鋼板のエッジ部に印加される電流密度を減少させることにより、エッジ部の過メッキ現象を防止したが、本発明では、陰極エッジマスクに陽極エッジマスクを追加し、鋼板のエッジ部側に印加される電流密度を減少させることにより、エッジ部の過メッキを革新的に改善した。 Conventionally, the cathode edge mask is brought close to the edge portion of the steel plate to reduce the current density applied to the edge portion of the steel plate, thereby preventing the overplating phenomenon of the edge portion. By adding an anode edge mask and reducing the current density applied to the edge side of the steel sheet, the overplating of the edge part was improved innovatively.
また、前記陽極エッジマスクは、陽極を覆う面積、すなわち鋼板のエッジ部と陽極との通電を遮断する面積が増減できるため、鋼板のエッジ部の電流密度を調節することが可能である。 Further, the anode edge mask can adjust the current density of the edge portion of the steel sheet because the area covering the anode, that is, the area where the conduction between the edge portion of the steel sheet and the anode is interrupted can be increased or decreased.
図２は本発明の一実施形態に係るエッジマスクの側面図である。図３は本発明の一実施形態に係るエッジマスクの斜視図である。図２および図３を参照すると、本発明の一実施形態に係る陰極エッジマスク１１は、鋼板のエッジ部に近接して設けられ、鋼板のエッジ部と陽極との通電を遮断することになる。このような陰極エッジマスク１１は、鋼板の方向に内部に溝が設けられており、鋼板に連続メッキを施すときにエッジ部を溝の内部に通過させることにより、陽極と鋼板のエッジ部との通電を遮断することができる。
FIG. 2 is a side view of an edge mask according to an embodiment of the present invention. FIG. 3 is a perspective view of an edge mask according to an embodiment of the present invention. Referring to FIGS. 2 and 3, the
前記溝は、鋼板の方向に広く傾くように設けられることが好ましい。鋼板の連続メッキの際に鋼板の幅方向に左右に移動する蛇行現象が生じるため、鋼板と陰極エッジマスク間１１の間隔が変化しても、衝突することなく鋼板のエッジ部の電流密度を安定的に減少させることができる。 The groove is preferably provided so as to be widely inclined in the direction of the steel plate. Since a meandering phenomenon that moves to the left and right in the width direction of the steel plate occurs during continuous plating of the steel plate, even if the distance between the steel plate and the cathode edge mask changes, the current density at the edge portion of the steel plate is stabilized without colliding Can be reduced.
また、陰極エッジマスク１１の他側面には支持部１３が連結され、前記支持部１３の一端は陰極エッジマスク１１を前後進させるマスク駆動部１６に連結される。よって、鋼板の連続メッキの際に、鋼板の蛇行現象が発生する場合に陰極エッジマスク１１を鋼板の方向に前後進させることにより、陰極エッジマスク１１の位置を調節することができる。前記マスク駆動部１６は、前後進が可能な装置であって、例えば、シリンダー装置であってもよい。前記マスク駆動部は、精密な制御のためにサーボモーターで駆動できる。
A
前記支持部１３には、上下方向に延設されて陽極エッジマスクを結合させることが可能な連結部１４が結合する。このような連結部１４は、支持部１３を貫通するように形成されてもよく、両側に２つのロード状に形成されてもよい。
Connected to the
前記連結部１４が陽極エッジマスク１２の位置調節ホール１５に挿入されることにより、陽極エッジマスク１２と連結部１４とが結合できる。陽極エッジマスク１２は、陰極エッジマスク１１を挟んで２つが平行に向かい合う形で結合でき、前記位置調節ホール１５が鋼板の方向に２つ以上設けられるため、連結部１４に結合する位置調節ホール１５の位置に応じて、陽極を覆う面積を調節することにより、鋼板のエッジ部の電流密度を調節することができる。
By inserting the connecting
一方、陰極エッジマスク１１および陽極エッジマスク１２は不導体で形成できる。また、陽極エッジマスク１２によって覆われた部分の未メッキ問題を防止するために、陽極エッジマスク１２は伝導性素材で形成できる。このとき、陽極２、３との通電を防止するために、陽極のエッジマスク１２は陽極２、３と向き合う面に不導体層が形成できる。この場合、陽極エッジマスク１２によって覆われる面に対して未メッキ問題が発生することを防止することができる。
On the other hand, the
図４は本発明の一実施形態に係るエッジ部の過メッキを防止するための電気メッキ装置の概略断面図である。 FIG. 4 is a schematic cross-sectional view of an electroplating apparatus for preventing overplating of an edge portion according to an embodiment of the present invention.
鋼板１は、負電荷を帯びて陰極の役割を果たし、２つの陽極２、３の間で進行しながら電気メッキが施されることになる。このとき、鋼板１の両側面のエッジ部は、電流密度が集中し、過度にメッキが行われるおそれがある。一次的に陰極エッジマスク１１が近接して配置されることにより、エッジ部の電流密度を減少させることになる。このとき、陰極エッジマスク１１と鋼板のエッジ部との間隔が広がっても、陰極エッジマスク１１と陽極２、３との間に形成された陽極エッジマスク１２によって陽極が覆われることになり、エッジ部の電流密度を減少させることが可能である。
The steel plate 1 is negatively charged and serves as a cathode, and is electroplated while proceeding between the two anodes 2 and 3. At this time, the current density is concentrated on the edge portions on both side surfaces of the steel plate 1, and there is a possibility that the plating is excessively performed. The
また、鋼板の進行の際に鋼板の幅方向に蛇行現象が発生して、鋼板１のエッジ部と陰極エッジマスク１１との間隔がやや広くなるとしても、陽極エッジマスク１２が陰極エッジマスク１１よりも鋼板１の方向にさらに長く形成されることにより、エッジ部に電流密度が急激に増加するのを防止することができる。
Further, even when the meandering phenomenon occurs in the width direction of the steel plate during the progress of the steel plate and the distance between the edge portion of the steel plate 1 and the
鋼板の厚さおよび種類に応じて、連結部１４に結合する陽極エッジマスク１２の結合溝１５の位置を変更することにより、陽極エッジマスク１２により通電が遮断される面積を調節することができる。
By changing the position of the
一方、鋼板１の蛇行の程度が激しくなる場合、支持部１３に連結される駆動部１６の動作によって陰極エッジマスク１１と陽極エッジマスク１２の全体位置を鋼板１の幅の変化に応じて対応するように調節することができる。
