Technical Field

The invention relates to the technical field of electroplating, in particular to electroplating equipment capable of reducing edge effect and a working method thereof.

Background

In the process of processing metal workpieces, electroplating is an extremely important link, a complete coating can prevent metal from being oxidized and improve the corrosion resistance of the workpieces, special coatings can improve the properties of wear resistance, conductivity and the like of the workpieces, electroplating is also commonly used for processing artware, and the luster and the hand feeling of the artware can be changed through the coatings.

Electroplating including rack plating, barrel plating, continuous plating etc., common rack plating equipment is mostly the integrative structure of welded type, in electroplating process, the rigidity of hanger, distance between adjacent hanger is also fixed, consequently produce edge effect easily, lead to cladding material thickness on closed angle and the edge to be greater than average thickness, and when the size of work piece is different, if still according to the mode of arranging of fixed hanger, can lead to great work piece and adjacent work piece interval to be close, overlap each other even between the work piece, influence cladding material quality.

Therefore, we propose an electroplating device and its working method which can reduce the edge effect.

Disclosure of Invention

s1, clamping a workpiece: respectively fixing the workpieces on a plurality of hangers to ensure that the workpieces are distributed uniformly as much as possible;

s2, electrolyte replenishing: observing the liquid level of the electrolyte in the plating tank, replenishing the electrolyte to reach a standard height, and then turning on a control switch to observe whether the equipment can work normally;

s3, electroplating: electroplating the workpiece, taking down the workpiece after electroplating, and preparing to carry out electroplating on the next batch of workpieces;

the working method of the electroplating equipment capable of reducing the edge effect also relates to electroplating equipment, which comprises a plating tank and a driving motor, wherein a positioning disc is rotatably arranged in the plating tank through a bearing, a plurality of hangers are circumferentially connected onto the positioning disc through a fixing seat, an output shaft of the driving motor is fixedly connected with a rotating shaft through a coupling, the rotating shaft and the positioning disc are coaxial and are fixedly connected with the positioning disc through a connecting disc, the bottom end of the rotating shaft is fixedly connected with a transmission mechanism, and an annular sealing box is arranged on the transmission mechanism in an interference fit manner;

annular seal box is opening downwards and with the sealed sliding connection's of bottom wall hollow cylinder in the coating bath hollow cylinder, sealed mounting has the polylith baffle in the annular seal box, the symmetric distribution has the polylith fixed plate on the interior diapire of coating bath, and every fixed plate all is located between two blocks of baffles that the position is corresponding and with the sealed slip of the lateral wall of annular seal box meet, the gas vent intercommunication that the annular seal box was seted up on its lateral wall through the symmetry has many blast pipes, and every gas vent all is located between two blocks of baffles that correspond.

The transmission mechanism comprises an intermittent component and an inner gear ring fixedly connected with the annular sealing box, the intermittent component comprises a cylindrical pin, a grooved pulley and an outer gear, the cylindrical pin is coaxially installed at the bottom of the rotating shaft and matched with the grooved pulley, the grooved pulley is coaxially and fixedly connected with the outer gear through a circular shaft, and the outer gear is meshed with the inner gear ring.

The invention has the beneficial effects that:

1. the pivot accessible connection pad drives the positioning disk and rotates for the work piece is in the rotation state, can disturb the electrolyte in the coating bath on the one hand, makes the ion distribution in the electrolyte more even, and edge effect when on the other hand can reduce electroplating makes the cladding material thickness on work piece surface unanimous.

2. Through setting up devices such as sheave, external gear, ring gear, baffle, fixed plate, can make the air in the annular seal box periodically pass through the blast pipe and spray to the hanger direction, increased the vortex effect to electrolyte on the one hand, make the ion distribution in the electrolyte more even, on the other hand, the air current can also take away the attached small bubble of work piece surface, avoids the cladding material that the bubble adheres to and leads to peel off the scheduling problem.

3. Through setting up devices such as ring channel, electrorheological fluids, solenoid, sliding seat, the position that the accessible control solenoid was interior current size adjusted the hanger makes the displacement control of hanger more accurate, and when the hanger position confirmed back, electrorheological fluids can play the effect of restriction sliding seat removal, guarantees that the relative position between the hanger does not change when electroplating.

4. Because many workpieces contain ferromagnetic metal, the current at the solenoid is cut off before electroplating begins, so that the magnetic field generated by the solenoid can be prevented from influencing the electroplating process of the workpieces, and the coating thickness is more uniform.
