Abstract
The utility model relates to an electroplating cathode shifter having circular motion, which belongs to a device for electroplating. The main working part of the electroplating cathode shifter having circular motion adopts a double-linking or a multi-linking parallelogram mechanism and uses a connecting rod of the parallelogram mechanism as a cathode conducting rod. When the electroplating cathode shifter having circular motion works, the cathode conducting rod does a parallel motion along a trace which is a circular, and a workpiece hung on the cathode conducting rod is driven to do the same circular motion. Compared with the present cathode shifter having straight reciprocating motion, the electroplating liquid which is near to the workpiece has higher renewing speed, and the utility model has stronger ability to prevent air bubbles from attaching. Thus, better electroplating-layer quality and higher electroplating efficiency are obtained.
Description
The utility model belongs to a kind of cathode moving device of electroplating usefulness, and particularly a kind of negative electrode conducting rod is made the parallel mobile cathode moving device of track for circle.
The negative electrode conducting rod of existing electroplating cathode running gear is all done straight reciprocating motion.Plating facts have proved, compare with the plating under the stationary state, negative electrode conducting rod band workpiece motion s, can make workpiece constantly touch new plating bath, quicken the speed that near the metal ion of workpiece replenishes, thereby accelerate metal deposition speed, improve galvanized productivity, and can make the coating crystallization fine and close more, improve the luminance brightness of coating and reduce burr; Simultaneously, because the souring that workpiece and plating bath relative movement produce, the hydrogen or other gas that produce in the time of can preventing to electroplate form bubble attached to workpiece surface, thereby avoid in defectives such as workpiece surface generation pin hole, pit and bubblings.But the mode of motion of existing cathode moving device is too simple, and only linear reciprocation in one direction so effect is good inadequately, often can not meet the demands.
The purpose of this utility model will provide a kind of electroplating cathode running gear of better effects if exactly.The key of this device is that the motion that the negative electrode conducting rod is done is that track is parallel mobile (the abbreviation circular motion) of circle.Compare with existing electroplating cathode running gear, the spatial dimension of motion expands to motion in the plane by motion on straight line, and travel direction is by " drawing circle " of back and forth becoming continuous change direction of motion along a fixed direction.Therefore, the regeneration function of plating bath and all further reinforcements of effect that prevent that bubble from adhering near the workpiece, thus can obtain better electroplating effect.
The circular motion of negative electrode conducting rod and workpiece is achieved through the following technical solutions:
On the support that is positioned at plating coating bath two ends, bearing is housed, axle is housed in the bearing, and the two ends of axle are fixed with eccentric stiffener (general available crank and crankpin, also available eccentric wheel and eccentric pin or use crank throw, also available in case of necessity bent axle), the eccentric stiffener on the diaxon links with connecting rod.Make the eccentricity of each eccentric stiffener identical, the width between centers of connecting rod two stomidiums is equated with the width between centers of two stands head bearing, so just respectively form a parallel-crank mechanism at the two ends of axle, the duplex parallel-crank mechanism is then formed at two ends altogether.Simultaneously, make the eccentric stiffener at same axle two ends have suitable phase differential (preferably 90 °), to eliminate the motion dead point of parallel-crank mechanism.Like this, when an axle rotation, just can drive whole duplex parallel-crank mechanism motion, wherein, eccentric stiffener is done turning motion, and connecting rod is then made track and moved for the parallel of circle.Connecting rod is made up of negative electrode conducting rod and the connecting rod head that is fixed on its two ends again, and the electro-conductive material manufacturing of negative electrode conducting rod can be joined by cable and power supply; Insulation between the connecting rod head insulating material manufacturing, other that can make negative electrode conducting rod and device partly.It more than is exactly the groundwork part of this device.In addition, power partly (as electric motor), speed change part (as worm gear reducer) and driving section (as shaft coupling, sprocket wheel, chain etc.) also are housed on support.During work, start power section, through speed change partly and driving part drive working portion, at this moment, the negative electrode conducting rod is just done track parallel mobile for circle, hangs over workpiece on the negative electrode conducting rod also along with doing same circular motion.
Some explanation:
1, the support of this device can be bound up with coating bath, also can not be bound up.
If 2 only need a negative electrode conducting rod, then another root connecting rod double as conducting rod not can be simplified when manufacturing and designing.
3, three negative electrode conducting rods if desired, then three parallel-crank mechanisms are partly adopted in groundwork, preferably 120 ° of the phase differential between each parallel-crank mechanism.More negative electrode conducting rods if desired can be with reference to same principle design manufacturing.
4, the size of rotating speed of eccentric stiffener and eccentricity roughly in 8～35 rev/mins and 30～100 millimeters scopes, should determine according to galvanized particular case by concrete value.
5, because the influence of hanger swing, the actual motion track of workpiece is not just round, but approximate circle, and this is to electroplating effect and have no adverse effects.As need limit the hanger swing because of certain reason, available binding method or other method are fixed on hanger on the negative electrode conducting rod, and this does not influence electroplating effect yet.
Below in conjunction with embodiment, do some again and specify:
Certain factory is in order to improve nickel-plated quality, adopted the shuttle cathode moving device of level, certain effect is arranged, but also do not reach requirement, still can produce some pin holes, pit at coating surface, think that by analysis the surface can adhere to still that bubble causes, carry several times up and down to break away from bubble so the workman have to be whenever just arrests of negative electrode conducting rod with hand a moment later, doing has like this increased working strength of workers greatly, and effect still is not ideal enough.This factory once wanted to do a kind of negative electrode that can tangential movement can move up and down off and on again and moves machine and replace manpower and improve the quality, and the back is because of complex structure, and effect also is not sure and does not do.After I learn above-mentioned situation,, invented the utility model and when the Jian Xinchang plating shop, implemented (externally not open as yet) through research.Implement model machine as shown in drawings, the first half of figure is a front view, and Lower Half is a vertical view.
1. being electric motor among the figure, 2. is shaft coupling, 3. is reduction box, 4. is chain, and sprocket wheel, are main drive shafts, and is mounted in the bearing (support only illustrates part on figure) on the support, and is a driven shaft; Fix a crank 5. at the two ends of every axle, crank is fixed with crankpin on 5.; 7. be the negative electrode conducting rod, 6. its two is fixed with connecting rod head, 7. with 6. form connecting rod, the borehole jack of 6. going up by connecting rod head is on crankpin ; 7. the negative electrode conducting rod is made with copper pipe, and available cable and power supply join; 6. connecting rod head uses the special carte manufacturing, makes between the other parts of negative electrode conducting rod and device to insulate; 6. and between the crankpin can adorn the bearing (not shown) at connecting rod head.4 cranks of this device eccentricity 5. is identical, and the width between centers of 2 connecting rod two stomidiums equates that with the width between centers between bearings at both ends the phase differential of the crank at same axle two ends is 90 °, so just consists of the duplex parallel-crank mechanism.Below it be coating bath 8., coating bath also have on 8. conductive anode rod (face not shown).During plating 9. 10. workpiece hung over the negative electrode conducting rod with hanger and 7. go up, and be immersed in the plating bath.If at this moment actuating motor 1., will through shaft coupling 2., reduction box 3., transmission chain 4., drive the motion of duplex parallel-crank mechanism, wherein, 5. crank does turning motion, and the negative electrode conducting rod is then made track and 10. also done same circular motion for the parallel mobile of circle and with workpiece.
The electroplating cathode running gear of this interplanting circular motion back effect that comes into operation is remarkable, has not only alleviated working strength of workers, eliminated the pin hole pit, and the luminance brightness of coating and electroplating efficiency is significantly improved all also.
