Description
Technical field：
The utility model is related to a kind of electroplating devices, and in particular to a kind of barrel plating machine for neodymium iron boron plating.
Background technology:
Neodymium iron boron is the powder metallurgy product of heterogeneous structure, due to the characteristics of itself compared to the plating on general monometallic surface
For, performance, plating speed to plating solution require relatively high.Since the electrochemical activity of different elements is different, matrix is being electroplated
Selective corrosion easily occurs in liquid, the rich neodymium of Sintered NdFeB magnet crystal boundary mutually easily preferentially corrodes, and then in coating
Surface forms pockmark shape corrosion interface.So how it is quick on be plated with the influence for reducing corrosion binding force between matrix and coating
It is the key that neodymium iron boron plating.Due to the influence of cathode efficiency, the addition of additive in electroplating process, cathode surface in addition to
Normal coating deposition, also with evolving hydrogen reaction；And the hydrogen being precipitated is accumulated in cathode surface, generates a large amount of bubble, is hindered
Normal sedimentation of the coating on matrix generates pin hole, and be easy to cause the hydrogen embrittlement peeling of later stage coating.
Utility model content：
The purpose of this utility model is to provide a kind of barrel plating machine for neodymium iron boron plating
A kind of barrel plating machine for neodymium iron boron plating including the roller being arranged in coating bath and is symmetricly set on roller
Two pairs of anodes of both sides；The overflow launder of upper end opening is equipped between a pair of of anode of the same side, the overflow launder is by overflowing
Flow tube is connect with the storage tank being located at outside coating bath；The storage tank is connected by the inlet of filter and coating bath.
Further scheme, the overflow launder are fixed on the inner wall of coating bath, in top ports and coating bath at the liquid level of plating solution
In same level.
Further scheme, the anode are hung in level frame on the anode stub of coating bath upper end, are placed in the liquid level of plating solution
Under.
Further scheme offers overflow port, described overflow pipe one end and the overflow port positioned at the top edge of overflow launder
Connection, the other end are connect with storage tank.
The utility model is equipped with the overflow launder of upper end opening, and the top of overflow launder between a pair of of anode positioned at the same side
Port and the liquid level of plating solution in coating bath are in same level.During plating, it would be desirable to which the workpiece of plating is put into roller, on roller
Equipped with cathode, and hole is offered on its external wall, plating liquid energy is freely accessible to.Coating is carried out to workpiece after opening power supply.It is being electroplated
In the process, the bubble that workpiece and anode surface generate, roller directional rotating power and by filter by plating solution in storage tank
The liquid level difference for being pumped into coating bath and being formed then will promptly enter in overflow launder with bladdery plating solution, then by overflow pipe into
Enter in storage tank；And the plating solution in storage tank by filter is pumped into coating bath and is formed into a loop to recycle again.
So the utility model, by adding overflow launder in electroplating device, with overflow technology, quick removal was electroplated
The particle to suspend in cathode and anode generates in journey bubble and plating solution reaches purification plating solution, improves quality of coating.

Specific embodiment：
As shown in Figure 1, 2, a kind of barrel plating machine for neodymium iron boron plating, including the roller 3 that is arranged in coating bath 4 and
It is symmetricly set on two pairs of anodes 2 of 3 both sides of roller；The overflow launder of upper end opening is equipped between a pair of of anode 2 of the same side
7, the overflow launder 7 is connect by overflow pipe 6 with the storage tank 5 being located at outside coating bath 4；The storage tank 5 passes through filter 9 and coating bath
4 inlet connection.
Further scheme, the overflow launder 7 are fixed on the inner wall of coating bath 4, top ports and the liquid level of plating solution in coating bath 4
In same level.
Further scheme, the anode 2 are hung in level frame on the anode stub 1 of 4 upper end of coating bath, are placed in the liquid of plating solution
Under face.
Further scheme offers overflow port 10 positioned at the top edge of overflow launder 7, and described 6 one end of overflow pipe is overflow with described
Head piece 10 connects, and the other end is connect with storage tank 5.
Overflow launder 7 is two in Fig. 1, is symmetricly set between a pair of of anode 2 at both ends, is respectively opened on each overflow launder 7
Then one overflow port 10 is connect by overflow pipe 6 with storage tank 5.
By conduit 8, the plating solution in storage tank 5 is pumped into coating bath 4 by filter 9, and due to the presence of coating bath 4 and storage tank 5
Liquid level difference, then plating solution enter in overflow pipe 6 through the overflow port 10 on overflow launder 7, subsequently into storage tank 5, so as to be formed
One cycle.In electroplating process, the bubble of workpiece and anode surface generation, in roller directional rotating power situation with plating solution
It quickly enters in overflow launder 7, then is entered in storage tank 5 by overflow pipe 6 together.So as to what cathode and anode in electroplating process was generated
The particle to suspend in bubble and plating solution removes in time, reaches purification plating solution, improves the purpose of quality of coating.
The above descriptions are merely preferred embodiments of the present invention, and not the technical solution of the utility model is made
Limitation in any form.On the premise of not departing from the spirit and scope of the utility model, the variation carried out to the utility model
Claimed the scope of the utility model is still fallen with improving.
