Title:
電気泳動浸漬塗装装置
Document Type and Number:
Japanese Patent JP4504362
Kind Code:
B2
Abstract:
Assembly to paint a workpiece by immersion in a bath, by electrophoresis, has electrode(s) within the bath with an initial polarity. At least one current supply unit (5A) converts alternating voltage into direct voltage with a given residual ripple factor, where one pole is connected to bath electrode and the other pole is connected to workpiece. A smoothing unit reduces residual ripple factor. The assembly to paint a workpiece by immersion in a bath, using electrophoresis, has at least one electrode within the bath with an initial polarity. At least one current supply unit (5A) converts an alternating voltage into a direct voltage with a given residual ripple factor, where one pole is connected to the bath electrode and the other pole is connected to the workpiece. It has a smoothing unit to reduce the residual ripple factor. The current supply unit has an uncontrolled diode rectifier bridge (19) and an insulated gate bipolar transistor (IGBT) circuit (22). The circuit includes a controlled oscillator (24) on one side, with a recurrence pulse rate of 5-30 kHz and preferably 20 kHz and with a variable pulse width. A power transistor (23) is controlled by the oscillator pulses.
