Embodiment
Below in conjunction with accompanying drawing with enumerate a kind of embodiment the structure of the utility model done explanation further:
Shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4; The utility model comprises: a plating tank 1 and the direct supply 3 that the required electric current of electrolysis is provided for electroplating technology that is used for the splendid attire electroplate liquid; Above plating tank 1, be provided with the cathodic metal crossbeam 21 and the anode metal crossbeam 22 that is used to hang coated metal spare that are used to hang plated body spare, cathodic metal crossbeam 21 is installed in activity with anode metal crossbeam 22 and waves on the support.On cathodic metal crossbeam 21, be hung with a current density design 4.
Described current density design 4 includes a bar shaped sheet material 41; Be provided with three reometer 42 in the upper end of bar shaped sheet material 41; The current signal output end of reometer 42 is connected with the wave input terminus of direct supply 3; The position that said bar shaped sheet material 41 is arranged in plating tank is provided with three and is used for conducting strip 43 that the electroplate liquid current density of plating tank is sampled, each piece conducting strip 43 and the 42 corresponding connections of a reometer.Bar shaped sheet material 41 preferably adopts pcb board, and conducting strip 43 parts are exposed, and the remaining circuit on the pcb board is provided with insulation layer.If three reometers 42 and three purpose of the corresponding conducting strip 43 that connects respectively are to gather out the current density value that electroplate liquid in the plating tank 1 is in three different positionss in upper, middle and lower; Get its MV then; In the practical implementation process; Can certainly adopt more conducting strip 43, perhaps also can be a conducting strip 43 that connects a plurality of different positionss simultaneously.Because current density design 4 is to hang 44 through bar shaped sheet material 41 on cathodic metal crossbeam 21 through the metal suspension member; That is to say between current density design 4 and plated body spare to being connected in parallel; Therefore; The current value that records according to reometer 42 also just draws the current density value of unit surface divided by the area of conducting strip 43.During use; Conducting strip 43 is inserted in the electrolyzer 1 near the position the plated body spare; Be used for the electroplate liquid current density of plating tank 1 is sampled, the current signal output end of current density design 4 is connected with the wave input terminus of direct supply, and direct supply 3 just can be learnt the current density on plated body spare surface according to the current density value of unit surface; Thereby realize adjustment, realized the purpose of automatic control output current value.
Conveniently in order using on the both sides of plating tank 1, all to read current value, on the positive and negative two sides of bar shaped sheet material 4 upper ends, all the conducting strip of establishing reometer and being used for gathering the electroplate liquid current density can be arranged.
Conducting strip 43 is corrosion resistant electro-conductive material, and for example: electro-conductive materials such as titanium alloy, stainless steel when conducting strip 42 uses for some time, after the surface formation coating, for fear of influencing accuracy of detection, can be put in conducting strip 42 in hydrochloric acid or the nitric acid and remove coating.
