Embodiment 1
[0018] This embodiment adopts the brush plating power supply controlled by the touch screen such as figure 1 As shown, it is adjusted and controlled by the touch screen 3 installed on the power supply casing. The schematic diagram of the power supply circuit is shown in figure 2 As shown, it is composed of input rectification circuit, inverter circuit, PWM pulse width modulation control circuit 1, high frequency transformer and output rectification circuit. The input rectifier circuit is composed of a rectifier bridge ZD, which is used to convert the input 220V AC power into DC power for the inverter circuit; the inverter circuit is a half-bridge topology inverter circuit composed of capacitors C2, C3, VMOS tubes V1, V2, and T1 , to convert the input direct current into an alternating voltage controlled by the PWM pulse width modulation control circuit 1, and output it to the primary of the high-frequency transformer T1; the high-frequency transformer T1 is used to step down...

The invention relates to an electro-brush plating power source controlled by a touch screen and belongs to the technical field of brush plating power sources. According to the power source, a touch screen (3) which is arranged on a case is connected with a micro controller unit (MCU) control circuit (2) by a serial port; embedded configuration software is arranged in the touch screen (3); by establishing a graphical control interface and touching control pels with different functions, different control instructions are sent and transmitted to the MCU control circuit (2) by the serial port to control a pulse-width modulation (PWM) control circuit (1) and output electrical parameters which meet requirements of the process of electro-brush plating. The power source has the technical effects that all control switches and regulating elements on former brush plating power source panels are replaced with the touch screen (3); ingress protection (IP) 65 of the panel of the touch screen (3) can effectively prevent erosion by brush plating solution; the operational handle is good; the graphical operation interface is convenient for the operation of brush plating; the labor intensity is reduced; and the quality of brush plating layers is improved.
Description
technical field [0001] The invention relates to a brush-plating power supply, in particular to a brush-plating power supply controlled by a touch screen, which is used to convert AC power input into DC power output, and belongs to the technical field of brush-plating power supplies. Background technique [0002] Usually, there are multiple process steps to complete a brush plating process, generally there are the following steps: electric cleaning - activation - plating transition layer - plating deposition coating, each process step has a great influence on the output voltage value and pole of the power supply. Different performance requirements require constant adjustment of the power supply. [0003] According to the applicant's understanding, the adjustment of the technical parameters of the existing electric brush plating power supply is mostly realized on the power panel through control elements such as changeover switches and knobs. During the brush plating process, ...
