Description

【0001】
【発明の属する技術分野】
本発明は、メッキ処理タンク内のメッキ処理液中でメッキ処理されるワークを水平方向に搬送させながらメッキする液中搬送式の電気メッキ装置であり、特に陰極バーへの通電グリースの塗布を不要にしたワーク搬送装置に関する。
【0002】
【従来の技術】
プリント基板などのワークのメッキ処理装置として、水平に固定配置された長尺の陰極バーに摺動自在に支持された治具によってメッキ処理されるプリント基板などのワークを懸垂状態に支持し、前記陰極バーに摺動接触されながら搬送される前記治具を介して前記陰極バーからワークへ給電しながら該ワークを横長のメッキ処理タンク内のメッキ処理液中を水平方向に連続搬送させながら電気メッキする液中搬送式の電気メッキ装置が知られている(例えば、特許第2943070号,特許第3065970号)。
【0003】
このような液中搬送式の電気メッキ装置にあっては、前記治具が陰極バーに沿ってスムーズに摺動されるようにするため、前記陰極バーの汚れ落し作業と前記陰極バーへの通電グリースの塗布作業を頻繁に行って摺動接触抵抗を小さくさせている。前記陰極バーとしては通電効率を考慮して銅製のものが広く用いられているが、銅製の陰極バーは特に腐蝕されやいすため、銅製陰極バーの汚れ落し作業とグリース塗布作業は特に頻繁に行わなければならず、これらの保守管理作業が面倒であり、しかも通電グリースの塗布作業の度にメッキ装置をストップさせなければならず処理効率が悪いものであった。
【0004】
しかも、陰極バーに塗布した通電グリースは油性で粘性を有することから、通電グリースを塗布された陰極バーには汚れが付着されやすく、付着した汚れによって陰極バーから治具の摺動接触部への給電効率が悪くなってしまう弊害があった。
【0005】
また、前記した液中搬送式の電気メッキ装置にあっては、メッキ処理されるワークをメッキ処理液中の陽極間の中央を通過するように搬送させながら電気メッキすることから、このワークを治具を介して摺動自在に支持する長尺の陰極バーは横長のメッキ処理タンク内のメッキ処理液の上部に配置させた装置が多い。このようにメッキ処理液の上部に陰極バーを配設した装置の場合は、陰極バーに塗布した通電グリース等の異物がメッキ処理タンク内のメッキ処理液中に落下してしまう恐れがあり、これら異物の液中落下によってメッキに悪影響を及ぼす弊害があった。
【0006】
【発明が解決しようとする課題】
本発明の目的は、水平に固定配置された長尺の陰極バーに摺動自在に支持された治具によってメッキ処理されるプリント基板などのワークを懸垂状態に支持し、前記陰極バーに摺動接触されながら搬送される前記治具を介して前記陰極バーからワークへ給電しながら該ワークを横長のメッキ処理タンク内のメッキ処理液中を水平方向に搬送させながら電気メッキする液中搬送式の電気メッキ装置において、前記治具が陰極バーに沿ってスムーズに摺動されるようにするために前記陰極バーに頻繁に塗布していた通電グリースの塗布を不要にし、この通電グリースを陰極バーに塗布しなくても治具が陰極バーに沿ってスムーズに摺動されるようにすることによって、この通電グリースの塗布によって生じていた前述の弊害を全て解消できるようにしたワーク搬送装置を提供しようとするものである。
【0007】
【課題を解決するための手段】
上記目的を達成するために、本発明の液中搬送式電気メッキ装置におけるワーク搬送装置は、水平に固定配置された長尺の陰極バー(1)に摺動自在に支持された治具(2)によってメッキ処理されるプリント基板などのワーク(W)を懸垂状態に支持し、前記陰極バーに摺動接触されながら搬送される前記治具を介して前記陰極バーからワークへ給電しながら該ワークを横長のメッキ処理タンク(3)内のメッキ処理液(A)中を水平方向に搬送させながら電気メッキする液中搬送式の電気メッキ装置において、前記陰極バーに振動を与ええるバイブレーター(5)を該陰極バーに付設し、このバイブレーターは前記陰極バーに沿って摺動接触されながら搬送される前記治具の搬送範囲における該陰極バーの全体に均等な振動を与ええるように搬送方向に離間させて複数配置してあり、これらのバイブレーターによって振動を与えられた前記陰極バーに沿って摺動接触されながら搬送される前記治具の摺動接触抵抗が減少されるように構成したことを特徴としている。
【0008】
【発明の実施の形態】
以下、本発明の実施形態について図面を参照しながら説明する。図1は本発明の側面図、図2は本発明の部分正面図、図3は本発明の全体を概略的に示した平面図である。
【0009】
本発明の液中搬送式の電気メッキ装置は、水平に固定配置された長尺の陰極バー1に摺動自在に支持された治具2によってメッキ処理されるプリント基板などのワークWを懸垂状態に支持し、前記陰極バー1に摺動接触されながら搬送される前記治具2を介して前記陰極バー1からワークWへ給電しながら該ワークWを横長のメッキ処理タンク3内のメッキ処理液A中を水平方向に搬送させながら電気メッキするものである。この液中搬送式の電気メッキ装置は、図2にその一部を示したように、多数のワークの各側端部を近接させた状態で液中を連続搬送させながらメッキするようにしている。このように連続搬送することによって、メッキ処理の効率化や各ワークの側端部にメッキが集中されるのを防ぎメッキの均一化を図れるようにしている。図1,3に示したように、前記メッキ処理タンク3内のメッキ処理液A中には適宜な支持手段によって多数の陽極4を離間して並列に配置している。図1ではこの陽極4としてアノードケース4a内にアノードボール4bを入れたものを用いている。前記メッキ処理液A中を搬送される前記ワークWは離間して並列に配置された前記陽極4間の中央を通過するように搬送されながら電気メッキされるように構成されている。
【0010】
図面に示した実施例では前記陰極バー1を断面矩形な平板にて形成している。この陰極バー1に沿って摺動接触されながら給電される前記治具2には前記陰極バー1の平らな面部と摺動接触される摺動接触部2aを有し、治具2の摺動接触部2aを介して陰極バー1から給電されるように構成されている。図1の実施例では前記治具2の摺動接触部2aを断面矩形な前記陰極バー1の上面と一方の側壁面(右側の側壁面)との各対応面で構成している。前記治具2の前記摺動接触部2aの下方には複数のクリップ式の製品挟持部2bを有し、このクリップ式の製品挟持部2bでプリント基板等のワークWを横向き姿勢で搬送されるように該ワークWの上部位置を着脱自在に挟持してこのワークを垂直な懸垂状態に支持できるように構成してある。メッキ処理液A中に入れられる前記治具2の前記製品挟持部2bは前記ワークWへの接点部を除きシリコンゴムなどの絶縁素材で被覆されている。前記治具2の摺動接触部2aから前記製品挟持部2bの接点部へと通電され、この接点部からワークWの上部位置へと通電されるように構成されている。
【0011】
図1乃至3において符号5は、前記陰極バー1に振動を与ええる複数のバイブレーターであり、これらのバイブレーター5は前記陰極バー1に付設されている。これら複数のバイブレーター5は、図3にその概略を示したように、前記陰極バー1に沿って摺動接触されながら搬送される前記治具2の搬送範囲における該陰極バー1の全体に均等な振動を与ええるように、同一の振動機能から成るものを搬送方向に等間隔の離間幅を設けて配置している。これらのバイブレーター5によって振動を与えられた前記陰極バー1に沿って摺動接触されながら搬送される前記治具2の摺動接触部2aの摺動接触抵抗が減少されるように構成される。
【0012】
前記陰極バー1に振動を与ええる前記バイブレーター5の取付けは、図1の実施例では、平板状の前記陰極バー1の被摺動接触部1aではない他方の側壁面(図1では左側の側壁面)に固着された固定部材7(図1に示した実施例ではチャンネル材)の上部にボルト結合にて取付けている。なお、前記陰極バー1から前記固定部材7側へ通電されないように該固定部材7は適宜な絶縁部材(絶縁樹脂板6などの)を介して前記陰極バー1に固着されている。このように、前記バイブレーター5を平板状陰極バー1の一側壁面側に取付け、陰極バー1の側壁面方向から陰極バー1へ振動を与えて、陰極バー1に図1において左右方向の振動を主に与えるようにしている。前記陰極バー1は固定フレームなどの適宜な固定手段で固定的に配置されているが、この実施例では前記陰極バー1を固定的に配置するための固定部材7(チャンネル材)を利用して、前記バイブレーター5を陰極バー1に取付けている。しかしながら、前記バイブレーター5の取付け手段は図に示した実施例に限定されるものではなく、前記陰極バー1の被摺動接触部1a以外の部分で陰極バー1に沿って搬送される治具2の搬送に支障のない陰極バー部分に適宜な固定部材を介して取付けることができる。
【0013】
なお、前記陰極バー1に摺動接触されながら該陰極バー1に沿って搬送される前記治具2の搬送駆動手段は特に限定されるものではないが、例えばこの実施例では、前記治具2に取付けられた係合爪10をエンドレス状の歯付き搬送ベルト11の係合歯で係合し、前記係合爪10を係合した前記歯付き搬送ベルト11の搬送駆動によって前記治具2を陰極バー1に沿って搬送するように構成した公知(特許第2943070号)の搬送駆動手段を用いている。その他、前記治具2の搬送手段としては、例えば、前記治具2の上部に突設した係合突起2cを図示しない適宜な押送体で押送して治具2を陰極バー1に沿って搬送するように構成した公知のいわゆるプッシャー式等も用いることができる。
【0014】
通電グリースを塗布してない断面矩形な平板の銅製陰極バー1に同一の振動機能をもつ複数のバイブレーター5を搬送方向に等間隔の離間幅で図1〜図3のように取付けて、これらのバイブレーター5の作動によって振動を与えられた前記陰極バー1に沿って図に示した摺動接触部2aをもつ前記治具2を適宜な搬送手段で摺動させる試験を実施した。この試験の結果、前記治具2の摺動接触抵抗が約20パーセント減少され、前記治具2を陰極バー1に沿ってスムーズに摺動させることができた。また、この試験の結果、前記陰極バー1から前記治具2への安定した給電が得られ、この給電効率になんら支障のない結果が得られた。なお、この試験では、前記バイブレーター5として、振動数100〜120回/秒の電磁式のバイブレーターを用いた。しかし、本発明に用いられるバイブレーターは、試験で用いた電磁式のバイブレーターに限定されるものではなく、エアー式等その他のタイプのバイブレーターも用いることができ、また、振動数も前記数値に限定されるものではなく、前記陰極バー1の形状や材質、この陰極バー1に沿って搬送される前記治具2やワークW等の諸条件を考慮して好適なバイブレーターを用いることができる。
【0015】
【発明の効果】
本発明によれば、水平に固定配置された長尺の陰極バー(1)に摺動自在に支持された治具(2)によってメッキ処理されるプリント基板などのワーク(W)を懸垂状態に支持し、前記陰極バーに摺動接触されながら搬送される前記治具を介して前記陰極バーからワークへ給電しながら該ワークを横長のメッキ処理タンク(3)内のメッキ処理液(A)中を水平方向に搬送させながら電気メッキする液中搬送式の電気メッキ装置において、前記陰極バーに振動を与ええるバイブレーター(5)を該陰極バーに付設し、このバイブレーターは前記陰極バーに沿って摺動接触されながら搬送される前記治具の搬送範囲における該陰極バーの全体に均等な振動を与ええるように搬送方向に離間させて複数配置してあり、これらのバイブレーターによって振動を与えられた前記陰極バーに沿って摺動接触されながら搬送される前記治具の摺動接触抵抗が減少されるように構成したことにより、前記陰極バーに通電グリースを塗布しなくても前記治具が陰極バーに沿ってスムーズに摺動されるため、今まで前記陰極バーに頻繁に塗布していた通電グリースの塗布を不要にでき、この通電グリースの塗布によって生じていた従来技術の弊害を全て解消できる。すなわち、通電グリースの塗布作業が不要なため、係る保守管理作業が容易であり、しかも塗布作業の度に装置をストップさせる必要がないため処理効率を高めることができる。また、汚れが付着されやすい油性の通電グリースの塗布を不要にしたため、陰極バーや治具の摺動接触部に汚れが付着されにくくなり、この汚れに起因した給電効率の悪化を解消できる。また、陰極バーへの通電グリースの塗布を不要にしたため、メッキ処理液の上部に陰極バーを配置したタイプのメッキ装置であっても、通電グリース等の異物の液中落下がほとんどなくなり、液管理が容易であり、しかも通電グリースの液中落下がなくなることによりメッキに悪影響を及ぼす弊害も解消できる。
【0016】
さらに、本発明によれば、バイブレーターによって振動を与えられた前記陰極バーから前記治具を介して結果的にワークへも振動が伝播されることから、ワークは振動を与えられながらメッキ液中を搬送されることになり、振動を与えられたワーク付近のメッキ液が攪拌されることによって、メッキの均一化やメッキ処理時間の短縮化が図れ、メッキ処理の効率化が図れる、という副次的なな効果も得られる。

TECHNICAL FIELD OF THE INVENTION
The present invention is a submerged transport type electroplating apparatus that performs plating while transporting a workpiece to be plated in a plating solution in a plating tank in a horizontal direction, and in particular, does not require the application of a conductive grease to a cathode bar. And a work transfer device.
[0002]
[Prior art]
As a plating apparatus for a workpiece such as a printed board, the workpiece such as a printed board to be plated by a jig slidably supported by a long cathode bar fixed and arranged horizontally is supported in a suspended state, Electroplating while continuously transporting the workpiece horizontally in the plating solution in the horizontally long plating tank while supplying power to the workpiece from the cathode bar through the jig transported while being slidably contacted by the cathode bar. There is known a submerged transport type electroplating apparatus (for example, Japanese Patent No. 2943070 and Japanese Patent No. 3065970).
[0003]
In such a submerged-type electroplating apparatus, in order to allow the jig to slide smoothly along the cathode bar, it is necessary to remove the stain on the cathode bar and energize the cathode bar. Grease is frequently applied to reduce the sliding contact resistance. Although the copper bar is widely used as the cathode bar in consideration of the current-carrying efficiency, the copper cathode bar is particularly susceptible to corrosion, so that the copper cathode bar is particularly frequently cleaned and greased. Therefore, such maintenance management work is troublesome, and the plating apparatus must be stopped every time the application work of the energized grease is performed, resulting in poor processing efficiency.
[0004]
In addition, since the conductive grease applied to the cathode bar is oily and viscous, dirt tends to adhere to the cathode bar to which the conductive grease is applied. There was a problem that the power supply efficiency deteriorated.
[0005]
In the above-described submerged transport type electroplating apparatus, since the workpiece to be plated is electroplated while being transported so as to pass through the center between the anodes in the plating solution, the workpiece is cured. In many cases, a long cathode bar slidably supported via a tool is arranged above a plating solution in a horizontally long plating tank. In the case of such an apparatus in which the cathode bar is disposed above the plating solution, foreign substances such as grease applied to the cathode bar may fall into the plating solution in the plating tank. There is an adverse effect on the plating due to foreign matter falling in the liquid.
[0006]
[Problems to be solved by the invention]
An object of the present invention is to support a work such as a printed circuit board to be plated by a jig slidably supported by a long cathode bar fixedly arranged horizontally and to suspend the work, and to slide on the cathode bar. A submerged transport type in which electroplating is performed while the workpiece is horizontally transported through a plating solution in a horizontally elongated plating tank while power is supplied from the cathode bar to the workpiece via the jig transported while being contacted. In the electroplating apparatus, in order to allow the jig to slide smoothly along the cathode bar, it is not necessary to apply energized grease frequently applied to the cathode bar, and apply the energized grease to the cathode bar. By allowing the jig to slide smoothly along the cathode bar without application, it is possible to eliminate all the above-mentioned adverse effects caused by the application of the conductive grease. It is intended to provide the workpiece transfer device.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, a work transfer device in a submerged transfer type electroplating device of the present invention includes a jig (2) slidably supported by a long cathode bar (1) fixed and arranged horizontally. ), A workpiece (W) such as a printed circuit board to be plated is supported in a suspended state, and the workpiece is supplied from the cathode bar to the workpiece via the jig conveyed while being slidably contacted with the cathode bar. A vibrator (5) for applying vibration to the cathode bar in a submerged transport type electroplating apparatus for performing electroplating while horizontally transporting a plating solution (A) in a horizontally elongated plating tank (3). Is attached to the cathode bar, and the vibrator can apply uniform vibration to the entire cathode bar in the conveyance range of the jig conveyed while being slid along the cathode bar. A plurality of jigs are arranged so as to be separated from each other in the conveyance direction, and the sliding contact resistance of the jig which is conveyed while being slidably contacted along the cathode bar vibrated by these vibrators is reduced. It is characterized by having comprised.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a side view of the present invention, FIG. 2 is a partial front view of the present invention, and FIG. 3 is a plan view schematically showing the whole of the present invention.
[0009]
The submerged-type electroplating apparatus of the present invention holds a workpiece W such as a printed board to be plated by a jig 2 slidably supported by a long cathode bar 1 fixed and arranged horizontally. The work W is supplied from the cathode bar 1 to the work W via the jig 2 conveyed while being slidably contacted with the cathode bar 1 and the work W is plated in a horizontally long plating tank 3. Electroplating is performed while transporting the inside of A in the horizontal direction. As shown in FIG. 2, the submerged transport type electroplating apparatus is configured to perform plating while continuously transporting the submerged liquid in a state in which the respective side ends of a large number of works are close to each other. . The continuous conveyance in this manner improves the efficiency of the plating process and prevents the plating from being concentrated on the side edge of each work, thereby making the plating uniform. As shown in FIGS. 1 and 3, a large number of anodes 4 are arranged in parallel in the plating solution A in the plating tank 3 with a suitable supporting means. In FIG. 1, an anode 4 having an anode ball 4b in an anode case 4a is used. The work W conveyed in the plating solution A is configured to be electroplated while being conveyed so as to pass through the center between the anodes 4 arranged in parallel at a distance.
[0010]
In the embodiment shown in the drawings, the cathode bar 1 is formed as a flat plate having a rectangular cross section. The jig 2 to which power is supplied while being slidably contacted along the cathode bar 1 has a sliding contact portion 2a which is slidably contacted with a flat surface portion of the cathode bar 1, and Power is supplied from the cathode bar 1 through the contact portion 2a. In the embodiment of FIG. 1, the sliding contact portion 2a of the jig 2 is formed by corresponding surfaces of the upper surface of the cathode bar 1 having a rectangular cross section and one side wall surface (right side wall surface). The jig 2 has a plurality of clip-type product holding portions 2b below the sliding contact portion 2a, and the clip-type product holding portion 2b conveys a work W such as a printed circuit board in a lateral posture. As described above, the upper position of the work W is detachably clamped so that the work can be supported in a vertically suspended state. The product holding portion 2b of the jig 2 put in the plating solution A is covered with an insulating material such as silicon rubber except for a contact portion to the work W. The power is supplied from the sliding contact portion 2a of the jig 2 to the contact portion of the product holding portion 2b, and is supplied from the contact portion to the upper position of the work W.
[0011]
In FIGS. 1 to 3, reference numeral 5 denotes a plurality of vibrators capable of giving vibration to the cathode bar 1, and these vibrators 5 are attached to the cathode bar 1. As shown schematically in FIG. 3, the plurality of vibrators 5 are uniformly distributed over the entirety of the cathode bar 1 in the transport range of the jig 2 which is transported while being slid along the cathode bar 1. Those having the same vibration function are arranged at equal intervals in the transport direction so that vibration can be given. The sliding contact resistance of the sliding contact portion 2a of the jig 2 conveyed while being slid along the cathode bar 1 vibrated by the vibrators 5 is configured to be reduced.
[0012]
In the embodiment of FIG. 1, the vibrator 5 for applying vibration to the cathode bar 1 is attached to the other side wall surface (the left side in FIG. 1) other than the sliding contact portion 1a of the flat cathode bar 1. It is attached to the upper part of a fixing member 7 (channel material in the embodiment shown in FIG. 1) fixed to the wall surface by bolting. The fixing member 7 is fixed to the cathode bar 1 via a suitable insulating member (such as an insulating resin plate 6) so that no electricity is supplied from the cathode bar 1 to the fixing member 7 side. In this manner, the vibrator 5 is attached to one side wall surface of the flat cathode bar 1 and a vibration is applied to the cathode bar 1 from the side wall surface direction of the cathode bar 1 so that the cathode bar 1 is vibrated in the left-right direction in FIG. I give it to the Lord. The cathode bar 1 is fixedly arranged by an appropriate fixing means such as a fixing frame. In this embodiment, a fixing member 7 (channel material) for fixing the cathode bar 1 is used. The vibrator 5 is attached to the cathode bar 1. However, the means for attaching the vibrator 5 is not limited to the embodiment shown in the drawing, and the jig 2 conveyed along the cathode bar 1 at a portion other than the slidable contact portion 1a of the cathode bar 1. Can be attached to the cathode bar portion which does not hinder the transfer of the toner via an appropriate fixing member.
[0013]
The transport driving means of the jig 2 which is conveyed along the cathode bar 1 while being slidably contacted with the cathode bar 1 is not particularly limited. For example, in this embodiment, the jig 2 The engaging claw 10 attached to the jig 2 is engaged with the engaging teeth of the endless-shaped toothed conveying belt 11, and the jig 2 is moved by driving the toothed conveying belt 11 engaged with the engaging claw 10. A known (Japanese Patent No. 2943070) transport driving means configured to transport along the cathode bar 1 is used. In addition, as a transporting means of the jig 2, for example, an engaging protrusion 2 c protruding from an upper portion of the jig 2 is pushed by an appropriate pushing body (not shown) to transport the jig 2 along the cathode bar 1. A known so-called pusher type or the like configured to perform the above-described operation can be used.
[0014]
A plurality of vibrators 5 having the same vibration function are attached to the copper cathode bar 1 having a rectangular cross section with no energized grease applied thereto and having the same vibration function as shown in FIGS. A test was conducted in which the jig 2 having the sliding contact portion 2a shown in the figure was slid by an appropriate transport means along the cathode bar 1 vibrated by the operation of the vibrator 5. As a result of this test, the sliding contact resistance of the jig 2 was reduced by about 20%, and the jig 2 could be slid smoothly along the cathode bar 1. In addition, as a result of this test, a stable power supply from the cathode bar 1 to the jig 2 was obtained, and a result having no hindrance to the power supply efficiency was obtained. In this test, an electromagnetic vibrator having a frequency of 100 to 120 times / second was used as the vibrator 5. However, the vibrator used in the present invention is not limited to the electromagnetic vibrator used in the test, and other types of vibrators such as an air type can also be used, and the frequency is also limited to the numerical value. Instead, a suitable vibrator can be used in consideration of the shape and material of the cathode bar 1 and various conditions such as the jig 2 and the work W conveyed along the cathode bar 1.

【The invention's effect】
According to the present invention, a work (W) such as a printed board to be plated by a jig (2) slidably supported by a long cathode bar (1) fixed and arranged horizontally is suspended. The work is supplied from the cathode bar to the work through the jig which is supported and slidably contacted with the cathode bar while being conveyed to the work in the plating solution (A) in the horizontally long plating tank (3). In a submerged transport type electroplating apparatus for performing electroplating while transporting the cathode in the horizontal direction, a vibrator (5) for applying vibration to the cathode bar is attached to the cathode bar, and the vibrator slides along the cathode bar. A plurality of the cathode bars are arranged apart from each other in the transport direction so as to give uniform vibration to the entirety of the cathode bar in the transport range of the jig which is transported while being in dynamic contact. The jig which is conveyed while being slid and contacted along the vibrated cathode bar is configured to have a reduced sliding contact resistance, so that it is not necessary to apply an energizing grease to the cathode bar. Also, since the jig slides smoothly along the cathode bar, it is not necessary to apply energized grease which has been frequently applied to the cathode bar until now. Can all be eliminated. That is, since the work of applying the current grease is not required, the maintenance management work is easy, and the processing efficiency can be improved since it is not necessary to stop the apparatus every time the work is applied. In addition, since it is not necessary to apply oily conductive grease to which dirt is liable to adhere, dirt does not easily adhere to the sliding contact portion of the cathode bar or the jig, and deterioration of the power supply efficiency due to the dirt can be solved. In addition, since it is not necessary to apply energized grease to the cathode bar, even in a plating apparatus of a type in which the cathode bar is disposed above the plating solution, foreign substances such as energized grease hardly fall into the liquid, and liquid management can be performed. In addition, it is possible to eliminate the adverse effect that plating does not have by adversely affecting the plating due to the fact that the conductive grease does not drop in the liquid.
[0016]
Furthermore, according to the present invention, since the vibration is consequently transmitted to the work via the jig from the cathode bar vibrated by the vibrator, the work is moved through the plating solution while being vibrated. By being transported, the plating solution near the vibrated work is agitated, thereby achieving uniform plating and shortening the plating processing time, thereby improving the efficiency of the plating process. Various effects can be obtained.
