In figure: 1-electroplates major trough, 2-feed liquor is responsible for, 3-overflow pipe, 4-circulating pump, 5-suction pump, 6-electrically-controlled valve, 7-electroplate liquid storage box, 8-filter, 9-goes out liquid portion, 10-baffle plate, 11-circulating slot, 12-feed liquor portion, 13-liquid back pipe, 14-discharging tube, 15-bottom surface, 16-digital flowmeter, 17-return duct, 18-bypass duct.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the technical scheme of this patent is described in more detail.
Refer to Fig. 1, flexible PCB electroplate liquid blood circulation, it includes plating major trough 1, circulating slot 11 and PLC control system, the bottom of plating major trough 1 is provided with discharging tube 14, the top of plating major trough 1 is provided with overflow pipe 3, and the cavity volume of circulating slot 11 is divided into feed liquor portion 12 and goes out the baffle plate 10 in liquid portion 9 by being internally provided with of circulating slot 11, and the lower end of baffle plate 10 is that closing is hardened structure, the cavity volume of circulating slot 11 is independently opened, closes height is circulating slot 11 cavity volume height the 1/5��1/2 of the structure that hardens; The upper end of baffle plate 10 is tower structure, is provided with the filter mesh layer being vertically arranged in the upper end of baffle plate 10; Discharging tube 14 and overflow pipe 3 connect the feed liquor portion 12 of circulating slot 11 each through pipeline, so that being deposited on the impurity bottom plating major trough 1 to be flowed into the feed liquor portion 12 of circulating slot 11 by discharging tube 14, the impurity floating on liquid level is made to be flowed into the feed liquor portion 12 of circulating slot 11 by overflow pipe 3, the liquid flowing into feed liquor portion 12 is flowed into out liquid portion 9 by after the filter mesh layer filtration on baffle plate 10 after standing, thus by the bigger impurity of baffle plate 10 elimination volume, achieve the pre-filtering to liquid, reduce the workload of filter 8; The lower end in feed liquor portion 12 is sequentially connected with filter 8 and circulating pump 4 by liquid back pipe 13, and circulating pump 4 is connected with the feed liquor supervisor 2 of plating major trough 1, is responsible for 2 at feed liquor and is provided with digital flowmeter 16 near plating major trough 1 notch place; Described go out liquid portion 9 connect a suction pump 5 by return duct 17, the outfan of suction pump 5 connects feed liquor supervisor 2, so make the electroplate liquid that only partial impurities content is higher be filtered through circulated filter system, improve the speed of circulation and the efficiency of filtration, it is to avoid waste; Being provided with a bypass duct 18 on described return duct 17, this bypass duct 18 connects an electroplate liquid storage box 7; Described discharging tube 14, liquid back pipe 13, overflow pipe 3, return duct 17 and return duct 17 are equipped with electrically-controlled valve 6; Described PLC Ore-controlling Role is PLC processor common in prior art and control panel, and described PLC control system electrically connects with described digital flowmeter and electromagnetic valve 6; The bottom surface 15 of described plating major trough 1 is the inclined-plane to the lopsidedness arranging discharging tube 14, thus guiding the liquid bottom plating major trough 1 to form the bottom surface 15 to plating major trough 1 form the flowing of souring, concurrently form washing away plating major trough 1 bottom land what discharge through discharging tube 14, be more conducive to the discharge of the impurity of deposition.
In electroplate liquid cyclic process, the parcel plating liquid being not involved in filtering is responsible for 2 by suction pump 5 through feed liquor and is directly returned plating major trough 1, digital flowmeter 16 on feed liquor supervisor 2 is monitored in real time and is entered the volume of electroplate liquid in plating major trough 1, when in entrance plating major trough 1, the volume of electroplate liquid is less than preset value, electroplate liquid in PLC system control and suck pump 5 suction electroplate liquid storage box 7 supplements, to ensure electroplating effect.
