From the information disclosed in the recent market, the horizontal electroplating mode still stays in the research and development stage, and no technology can really realize mass production; the main focus of the horizontal electroplating method is the communication mode between the rectifying power supply and the conductive film on the surface of the battery piece. In general, a battery piece realizes a path for electrifying a cathode, one is to switch on a power cathode through a conductive brush, and the conductive brush is fixed in a path section of the plating tank, through which the battery piece passes; the other is that the shaft for carrying the battery piece transmission and the roller are made into conductive materials so as to be communicated with the cathode; by adopting the method, when the surface coating of the battery piece is implemented, metal ions can be synchronously deposited with the surface of the battery piece because the conductive brush and the roller assembly are in an electric field environment. Therefore, each production period needs to stop for film stripping treatment on the surface of the conductive brush and the roller assembly; this will greatly reduce the effective utilization of the equipment and increase the maintenance costs of the equipment.
The prior art has the following disadvantages: 1) The VCP electroplating mechanism is adopted, so that the volume is large, the manufacturing and maintenance cost is high, the productivity is low, and a large amount of manpower and material resources are required to be input in the whole equipment manufacturing and production and use links, so that the industrial benign development is not facilitated; 2) The contact type horizontal electroplating device is adopted, so that the film stripping treatment operation is frequent, the maintenance cost is high, the equipment utilization rate is low, and the continuity of an automatic production line is not facilitated. Therefore, the prior art has shortcomings.
