Abstract
The utility model provides a device for automatically controlling current of a rectifier and solves the problem that the plating layer of material sheets is uneven because the current of the rectifier in an electroplating bath station is varied in real time as a result of uncertainties such as falling of the material sheets. The device comprises a material sheet steel conveyor belt (2), material sheets (3) which are clamped on the material sheet steel conveyor belt (2) and an electroplating bath (4). The material sheet steel conveyor belt (2) movably passes through the electroplating bath (4). A charging device (1) is fixedly arranged on one side of the front end of the material sheet steel conveyor belt (2). A material sheet proximity transducer (5) is arranged on the left side of the electroplating bath (4). The electroplating bath (4) is electrically connected with the rectifier (6). A control system (7) is respectively and electrically connected with the charging device (1), the material sheet proximity transducer (5) and the rectifier (6). The utility model improves the quality of the plating layer of the material sheets.
Description
Technical field
The utility model relates to a kind of high speed electrodeposition production line to circuit lead frame, the device that particularly a kind of electric current of the rectifier that the electrode of electroplating assembly line is powered is controlled automatically.
Background technology
The high speed electrodeposition production line of existing integrated circuits lead frame is that feeding device is clamped in the circuit lead frame tablet on the steel band, and steel band carries tablet successively by each electroplating technology hopper.Tablet arrives the electroplating technology hopper needs certain hour to postpone, therefore, from operations such as material loading, material loading end, tablet replacings, and transport that uncertain factor causes coming off of tablet in the steel band operational process of tablet, the capital causes the real-time change of rectifier current in the plating tank station, causes inconsistent to the tablet thickness of coating.
Summary of the invention
The device solves of the automatic control rectifier current that the utility model provides existing lead-in wire to printed circuit board (PCB) can not in time control adjustment when carrying out in the production line of high speed electrodeposition the real-time change of rectifier current in the plating tank station, cause the inconsistent technical problem of tablet thickness of coating.
The utility model overcomes the above problems by following scheme:
Automatically control the device of rectifier current, comprise that tablet transmits steel band, tablet and the plating tank of mounting board on tablet transmission steel band, described tablet transmits steel band movable transmission from plating tank to be passed through, a side that transmits the front end of steel band at tablet is set with feeding device, be provided with the tablet proximity transducer in the left side of plating tank, plating tank and rectifier are electrically connected, and Controlling System is electrically connected with feeding device, tablet proximity transducer and rectifier respectively.
In Controlling System, be provided with PLC, in PLC, be provided with the computer-controlled program of control rectifier current.
The utility model has solved that uncertain factor causes that rectifier current change in real time causes the inhomogenous problem of tablet coating in the coating bath station because tablet comes off etc., has improved the tablet quality of coating.
