Referring to fig. 1 and 2, an embodiment of the present invention includes:

an anode assembly for barrel plating, the anode assembly for barrel plating having two sets symmetrically disposed at both sides of a barrel 1 in a plating bath, each set of the anode assembly for barrel plating comprising: the electroplating device comprises a copper bar 5, two suspension mechanisms and anode plates 2, wherein the copper bar 5 is symmetrically arranged on two sides of the electroplating pool, each suspension mechanism comprises a suspension beam 3 and two suspension columns 4, one end of each suspension column 4 is fixed on the suspension beam 3, the other end of each suspension column 4 is connected with the end of the copper bar 5 through a bolt, the top end of each anode plate 2 is provided with a

hook

6, and 2 anode plates 2 are suspended on the suspension beam 3 through the hooks 6; the suspension beam 3 and the anode plate 2 are all immersed below the liquid level of the electroplating pool. According to above-mentioned mode, the copper bar 5 is connected indirectly to the suspension structure that anode plate 2 constitutes through hanging roof beam 3 and hanging post 4, because anode plate 2 and hanging roof beam 3 all submerge under the liquid level, consequently, anode plate 2 can not the oxidation rust, and through bolt fixed connection again between hanging post 4 and the copper bar 5, can effectively prevent because contact failure between anode plate 2 that anode plate 2 rusts and the copper bar 5 that arouse leads to the unstable copper element pollution problem that influences cladding material quality problem and copper bar 5 spatters the plating bath and leads to, improve the stability of electroplating operation.

The anode plate 2 is provided with a through hole structure. The diameter of the through hole structure on the anode plate 2 is 6 times of that of the through hole on the roller 1 in the corresponding electroplating pool.

The reason why the diameter of the through hole on the anode plate 2 is larger than that of the through hole on the roller 1 in the electroplating pool is that if the diameter of the through hole on the anode plate 2 is too small, the flow speed of the electroplating solution before and after the anode plate 2 is smaller than the exchange speed of the electroplating solution inside and outside the roller 1, and the difference of ion concentrations in different areas in the electroplating pool is large, so that the electroplating effect is influenced by the non-uniform lead-in current.

The length of the anode plate 2 is 1.5 times of the diameter of the roller 1, the anode plate 2 is bent towards the roller 1 from the 2/3 height of the plate surface, and the bending angle of the anode plate 2 is 30 degrees.

The reason why the diameter of the through hole on the anode plate 2 is larger than that of the through hole on the roller 1 in the electroplating tank is that if the diameter of the through hole on the anode plate 2 is too small, the flow speed of the electroplating solution before and after the anode plate 2 is smaller than the exchange speed of the electroplating solution inside and outside the roller 1, and the difference of ion concentrations in different areas in the electroplating tank is large, so that the electroplating effect is influenced by the uneven lead-in current.
