Description

The barrel plating device

Technical field

The present invention relates to a kind of barrel plating device, be specifically related to be suitable for small workpiece is implemented galvanized barrel plating device, for example the above-mentioned conducting strip on the object (workpiece) that conducting strip is installed in the part of the little ceramic substrate of growing 0.2～1mm is carried out galvanized barrel plating device.

Background technology

As previously mentioned, in small workpiece being implemented galvanized barrel plating device, the small workpiece in importantly preventing to turn round enters the gap (bearing portions) between electrode (negative electrode) lead-in wire that is installed in cylinder two ends rotating center section and the inserting hole of the inserting logical this lead-in wire.Its reason is at the bearing portions of contact conductor, for the cylinder of rotation, because non-rotatably slotting electrify electrode lead-in wire enters this bearing portions as small workpiece, can damage the insulation layer of covering lead-in wire and the inner peripheral surface of above-mentioned inserting hole, or hinder the rotation of cylinder.

For example open in the 2002-256500 communique, put down in writing the structure of the bearing portions of barrel plating device as shown in figure 11 the Japanese Patent spy.

In Figure 11, the barrel plating device has idler frame 2a, and it connects the opposed support unit 20a of a pair of prescribed distance of being separated by by a plurality of union levers.Under the state that is positioned on the same axis of level, piped bolster 4a is installed on each support unit 20a by screw 44a with connecting shape separately.

The end plate 31a that cylinder 3a fixes these cylindrical shell two ends by cylindrical shell, the blocked state of not shown hollow (for example sexangle tubular) constitutes, and the lid of free switch is installed at cylindrical shell end face on one side.For seeing through electroplate liquid, on the cylindrical shell of cylinder, be assembled with porous plate with some apertures.

With respect to horizontally rotating the axle center, the both ends of cylinder 3a approximately tilt 11 ° towards vertical direction, and can be rotated to support on each bolster 4a.That is, be fixed on hub-like parts 31b on the bearing portions of cylinder end plate 31a, be installed in rotation on the end of the opposite side of bolster 4a by super-high density polyethylene system bearing 49a.Vertical fixing is thought the rotation of cylinder transmission from the motor of scheming not show as the extreme gear 60a that rotates transfer means on these hub-like parts 31b.

The hollow bulb 40a of tubular support axle 4a has the 40b of large diameter portion of cardinal extremity one side and the little inside diameter 41a of opposite side end, on the lining 32a that is installed on the cylinder end plate 31a, form inserting hole 32b in the mode that forms the axis identical with the axis of the hollow bulb 40a of bolster 4a by super-high density polyethylene system.

With hollow bulb 40a on the slotting logical bolster 4a of contact conductor 10a and the inserting hole 32b on the lining 32a, arrive in the cylinder with the outside from support unit 20a.Insert under the logical state at this kind of lead-in wire 10a, the internal diameter of above-mentioned little inside diameter 41a is set at the size of the periphery that is close to this lead-in wire 10a, and the internal diameter of inserting hole 32b is set at the size that can stop workpiece to flow into the gap between inserting hole 32b inner peripheral surface and the lead-in wire 10a periphery.

Periphery at above-mentioned lead-in wire 10a covers the insulation layer that is made of rubber, and the part of this lead-in wire 10a in the cylinder inboard is bent downwardly, and its top ends is connected with electrode (negative electrode).

The installation constitution of the contact conductor of cylinder the other end, the extreme gear 60a that does not have the rotation transfer means among Figure 11, bolster 4a are than the weak point shown in Figure 11, and be in addition, identical with the installation constitution of Figure 11.

Use above-mentioned barrel plating device, as electroplating to the workpiece that for example constitutes by the micro chip electrical condenser about diameter 0.3mm, its operation is to open the lid of cylinder earlier, with workpiece and master body measure in accordance with regulations drop into inside after, close loam cake, 2a puts into plating tank with cylinder together with resting support, makes the electroplate liquid in the cylinder immersion plating groove, giving under the state of electrifying electrodes the low speed rotation cylinder.After workpiece having been implemented plating, 2a transfers to cleaning layer with cylinder from electrolytic coating together with resting support, and is with the master body cleaning workpiece, dry then.

Above-mentioned barrel plating device, as previously mentioned, contact conductor is installed, because the internal diameter of the little inside diameter 41a of bolster 4a is set at the size that is close to this lead-in wire 10a periphery, and, the internal diameter of inserting hole 32b is set at the size that can stop workpiece to flow into the gap between inserting hole 32b inner peripheral surface and the lead-in wire 10a periphery, so workpiece can not flow into the gap of bearing portions.

Therefore, can prevent that workpiece from entering the drawback that cause in inserting hole 32b and the gap (gap of bearing portions) of lead-in wire between the 10a, the workpiece that insulation layer breakage, the cylinder that for example covers lead-in wire 10a can not rotate, enter above-mentioned gap smoothly mixes with the workpiece of follow-up input and causes poor plating etc.

But if adopt above-mentioned barrel plating device, at bearing portions, the formation precision of the insulation layer of lead-in wire is low, and the coefficient of thermal expansion height.Therefore, for example, when the above-mentioned conducting strip on the workpiece that conducting strip is installed in the part of the little ceramic substrate of long 0.2～1mm is electroplated, consider the low and coefficient of thermal expansion of formation precision of insulation layer, being difficult to internal diameter with the inserting hole 32b of the lining 32a on the side plate of cylinder, to be controlled at the gap that above-mentioned workpiece or its part do not enter between this inserting hole 32b inner peripheral surface and the lead-in wire 10a be the size in the gap of bearing portions.

And in the size of the inserting hole 32b that can not suitably control lining 32a and under the smaller situation of this inserting hole 32b, when cylinder rotate, the periphery strong friction of the inner peripheral surface of this inserting hole 32b and the 10a that goes between made the rotation difficulty of cylinder.In addition, because the wearing and tearing of the insulation layer of lead-in wire 10a make gap between the two increase the drawback that the part of generation workpiece or workpiece enters this gap.In addition, in the size that can not suitably control inserting hole 32b and under the bigger situation of this inserting hole 32b, when cylinder rotates, the drawback that the part of generation workpiece or workpiece enters this gap.

Enter gap between inserting hole 32b inner peripheral surface and the lead-in wire 10a as the part of workpiece or workpiece, can stop up this gap, the insulation layer that damage covers lead-in wire 10a appears, or make the rotation of cylinder not smooth, or the workpiece that stops up above-mentioned gap after plating when cylinder takes out workpiece remains in the cylinder drawbacks such as reduction plating uniformity.

Summary of the invention

The purpose of this invention is to provide a kind of barrel plating device; can be on the cylinder end plate that rotates the adequately protect insulation layer of lead-in wire of the bearing portions of through electrode lead-in wire; can control the gap size of this bearing portions easily, not make small workpiece or its part enter this gap.

In the present embodiment, whole lead-in wire 10 and the energized components 5 that forms in the 1st embodiment is integrally formed in bolster 4 under the situation of not establishing cover portion 42.

Other formation and action effect are approximately identical with the 1st embodiment, omit its explanation.

Other embodiment

In the respective embodiments described above, mounting bush 32 in the inserting hole 312 on the end plate 31 of cylinder 3, but also can omit this lining 32, when cylinder 3 rotations, the inner peripheral surface of inserting hole 312 slides with respect to the periphery of axle sleeve 12.

In the 1st embodiment, with screw 47 fixing adjustment plate 46 of adjusting lead-in wire 10 postures on energized components 5, but go up the fixing plate 46 of adjusting at bolster 4 (linking part cover 41) with identical screw 47, have same effect.

In the above-described embodiment, the downward bent part 101 of lead-in wire 10 forms the angled straight lines shape, but this downward bent part 101 also can form circular-arc or cerioid, forms convex at oblique upper or tiltedly.

As adopt barrel plating device of the present invention, and connect the bearing portions of the end plate 31 of cylinder 3 at lead-in wire 10, because the axle sleeve 12 that wear parts constitutes is installed, can protect the insulation layer 104 of this part lead-in wire 10 on lead-in wire 10.In addition, axle sleeve 12 is owing to be the parts that are different from the insulation layer 104 of lead-in wire 10, can select good processability and material that coefficient of thermal expansion is low is made this axle sleeve, can control the gap size of this bearing portions, and small workpiece or its part can not be entered.

Because axle sleeve 12 is the parts that are different from lead-in wire 10, be convenient to install and change.
