All the rollers passing through the film base materials 4-8 on the film running path are designed to be vertically installed from unreeling to reeling, and certain installation parallelism exists between the rollers. The problem that the effective electroplating length on the V-shaped routing path in the conventional scheme is small is solved, the maximum effective electroplating length is realized on the shortest routing length, and the occupied area length of equipment is shortened; the effect that double-sided electroplating is completed in one plating bath is realized, the structure of electroplating equipment is simplified, the number of conductive rollers required to be matched in the plating bath is greatly reduced, and the cost of the equipment is reduced.
Referring to fig. 1 to 4, the principle of operation of the water electroplating apparatus for electroplating the surface of the flexible film substrate according to the present invention is as follows:
in the embodiment of the utility model, the film base materials 4-8 to be electroplated are arranged on the unwinding roller 1, and the end part of the film sequentially passes through the electroplating part and the winding part; switching on a power supply of an electroplating part, and performing film electroplating through the water transition liquid in the plating solution tank 4, the anode plate 4-4 and the conductive copper strip 4-3 to form a plating layer on the surface of the film; according to the principle of electroplating, in order to realize a certain coating thickness in the plating solution pool 4, the film base materials 4-8 to be plated pass through a certain electroplating time T and apply total current I, the electroplating time T can be calculated according to the running speed V of equipment and the path length of the film base materials 4-8 in the plating solution, the coating thickness of the surfaces of the film base materials 4-8 on the electroplating path is a gradually thickening process, along with the thickening of the coating, the conductivity of the film base materials 4-8 is continuously improved, and the overcurrent capacity is continuously enhanced, so that on the path of the coating, the current applied to the anode plates 4-4 which are uniformly and equidistantly distributed also needs to be gradually increased according to the overcurrent capacity to form a rule of gradient increasing, and meanwhile, the total current of all the anode plates 4-4 is ensured to meet the requirement of coating thickness growth. The design control of the production speed of the whole electroplating equipment is realized by increasing or decreasing the diameter of the electroplating main roller 4-2, the number of the anode plates 4-4 corresponding to the guide roller 4-7 for guiding the film base material 4-8 and the gradient configuration of the current density of the anode plates 4-4.
After electroplating, cleaning and carrying out anti-oxidation treatment on the film plated with the plating layer, and then sending the film into a coiling part; after the film fed into the winding part is dried, an edge cutter is arranged at the outlet of a flattening roller 13 at the rear end of an oven 12, waste materials at the rear ends of the edge-cut edges at two sides of the electroplated film substrate 4-8 are wound through a waste material roll, the tension of the electroplated film substrate 4-8 is controlled through a tension roller 14 in the middle, and finally the electroplated film substrate 4-8 is guided into a winding roller 16 through a compression roller 15 to be wound, so that the whole process of film electroplating and winding is completed.
The embodiment of the utility model cancels the structure of the conductive roller of the plating bath 4, realizes the thin film conduction by matching with the conductive copper strip 4-3, and simultaneously does not generate copper plating on the surface of the electroplating main roller 4-2, thereby avoiding the puncture or scratch of the film surface caused by the copper plating; the tension on the film surface is effectively reduced, so that the surface deformation of the film base materials 4-8 is reduced in the production movement process, and the product percent of pass is improved; the conductive copper strip 4-3 and the thin film base material 4-8 are both in the plating solution in the whole electroplating process, so that the heat dissipation problem when the conductive copper strip 4-3 and the thin film base material 4-8 are electrified is effectively solved, and the hole burning problem is avoided; the film is vertically moved, so that the problem of small ratio of effective electroplating length is solved, the maximum effective electroplating length is realized on the shortest film moving length, and the occupied area length of equipment is shortened; the effect that double-sided electroplating is finished in one plating solution tank 4 is realized, the structure of electroplating equipment is simplified, and the cost of the equipment is reduced.
