Accompanying drawing explanation
Fig. 1 is that the present invention detects plating line current anomaly and adjusts the method flow diagram of electric current.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the present invention is described further:
With reference to figure 1, method of the present invention is applied on the treater of plating line equipment, plating line equipment comprises: power control unit, supply transformer, plating cylinder, current sensor, treater and warning howler, supply transformer comprises multiple and is controlled by power control unit respectively, each supply transformer corresponds to a plating cylinder and is electrically connected, each plating cylinder correspondence is connected with a current sensor, multiple current sensor is electrically connected with treater respectively, treater and power control unit are electrically connected, warning howler comprises multiple, each warning howler corresponds to a plating cylinder, and be electrically connected with power control unit respectively.The size that power control unit is used for the predetermined current sent according to treater controls corresponding supply transformer to electroplating the cylinder output electric current identical with the size of predetermined current accordingly, and controls the switch of warning howler.
Because treater needs responsible a large amount of logic and to export data frequent, can likely there is system class fault, except system class fault, also may occur that hardware fault causes current anomaly, even if break down, probability is little, but once occur just making a large amount of pcb boards scrap, therefore need, for the method for treater increase measuring and adjustation current parameters, hardware only to need increase current sensor and warning howler.
Method is the method detecting plating line current anomaly and adjust electric current, comprises the following steps:
S101: the size being obtained the electric current of the plating cylinder that it is monitored by current sensor, this electric current is designated as actual current.
S102: the size obtaining corresponding predetermined current according to the procedure position at the pcb board place of electroplating in this plating cylinder.Because the plating of complete pcb board needs multiple working procedure, every procedure performs in different plating cylinders, different operations in requisition for electric current also can be different, therefore need to know which procedure the pcb board electroplated in this plating cylinder is positioned at, thus obtain the size of corresponding predetermined current.
S103: judge that the size of actual current is whether in the magnitude range of predetermined current, if so, then represents the working properly of this plating cylinder, if not, then send guard signal to the warning howler that this plating cylinder is corresponding, and perform S104.
The size of predetermined current is occurrence, but be that permission is devious in the process of implementation, if therefore the size of actual current is no more than predetermined deviation scope, then can think working properly, and predetermined deviation scope is the magnitude range of predetermined current, the size of such as predetermined current is 50A, and can set predetermined deviation scope according to the actual requirements in 90%-110%, namely the magnitude range of predetermined current is 45A-55A.If beyond the magnitude range of predetermined current, then can start corresponding warning howler by power control unit and report to the police, inform that staff finds current anomaly.
S104: input in power control system by the size of predetermined current, makes power control system change the size of the electric current inputing to this plating cylinder the size of predetermined current into.While warning, can the size of predetermined current be inputed in power control system as emergency processing, by supply transformer, the size of current in the plating cylinder of correspondence be changed into the size of predetermined current by power control system.Owing to giving the alarm before, also can the size of current after adjustment be checked when therefore staff checks fault, to guarantee that the size of current of electroplating in cylinder is normal.
The beneficial effect of present method: the electric current in plating cylinder is monitored by current sensor, when noting abnormalities and alarm transfer default current value and adjust, not only can monitor the current anomaly of each plating cylinder, automatically electric current can also be adjusted, pcb board is avoided to scrap in a large number, can significantly improving product quality, improve and produce yield.
