DETAILED DESCRIPTION

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] like Figure 1 The double-station dual-power electrolysis system shown is divided into two electrolysis stations on the left and right, and is provided with a touch screen 1. The touch screen 1 is connected to the PLC controller 2 through a No. 1 communication line 16, and the station connection is performed through the port of the PLC controller 2. The left electrolysis station on the left is connected to the No. 1 electrolysis power supply 4 through the No. 2 communication line 3 by the left port of the PLC controller 2. The negative pole of the No. 1 electrolysis power supply 4 is connected to the negative pole 5 of the left electrolysis station through a No. 1 wire 7. The positive pole of the No. 1 electrolysis power supply 4 is connected to a No. 1 diode 6, and is connected to the positive pole 9 of the left electrolysis station through a No. 2 wire 8.

[0017] Similarly, the right electrolysis station is connected to the No. 2 electrolysis power supply 14 through the No. 3 communication line 15 by the right port of the PLC controller 2. The negative pole of the No. 2 electrolysis power supply 14 is connected to the negative pole 12 of the right electrolysis station through the No. 6 wire 13. The positive pole of the No. 2 electrolysis power supply 14 is connected to the No. 2 diode 17 and is connected to the positive pole 10 of the right electrolysis station through the No. 4 wire 11.

[0018] The first diode 6 and the second diode 17 are both high-power Schottky diodes, and the high-power Schottky diodes are added at the output ends of the two power supplies to prevent the two power supplies from being connected in series.

[0019] During operation, the electrolysis voltage, discharge time and discharge frequency of the left electrolysis station and the right electrolysis station are set respectively on the human-machine interface of the touch screen 1, and the touch screen 1 transmits the set parameters to the PLC controller 2 through the No. 1 communication line 16, and the PLC controller 2 transmits the electrical parameters to the No. 1 electrolysis power supply 4 and the No. 2 electrolysis power supply 14 through the 485 communication of the No. 2 communication line 3 and the No. 3 communication line 15, and the positive and negative poles of the electrolysis stations of the two stations are connected respectively through the No. 1 electrolysis power supply 3 and the No. 2 electrolysis power supply 14, and the workpieces to be electrolyzed are connected to the negative poles of the respective electrolysis stations, and the tool electrode is connected to the positive pole of the electrolysis station, so that the double-station double-power electrolysis processing can be realized. This double-station double-power electrolysis system can realize electrolysis processing of two products or two different positions of a product at the same time with different voltages, frequencies and discharge times in one working cycle.

[0020] In summary, the dual-station dual-power electrolysis system is divided into two electrolysis stations on the left and right through a dual-station design. Electrolysis processing of the two stations can be carried out simultaneously, which improves processing efficiency. Through the dual power supply design, each station is powered by an independent power supply, avoiding the problem of two power supplies being connected in series, and ensuring the stability of the system. A touch screen human-computer interaction interface is established, and the electrolysis voltage, discharge time and discharge frequency can be set separately through the touch screen. The operation is convenient and the parameters can be adjusted easily. It is connected to the PLC controller through a communication line. The PLC controller can control the electrolysis power supply and transmit the set parameters to the electrolysis power supply, realizing automatic control.

[0021] The benefits of this system are: the dual-station design allows two stations to process at the same time, reducing processing time. The dual power supply design avoids the problem of power supply series connection, reduces the failure rate, and also reduces the time and cost of replacing electrolytic equipment. The electrolytic parameters can be easily adjusted through the touch screen, reducing the difficulty of operation. The system can perform electrolytic processing on two products or two different positions of the product at the same time, which is suitable for the production of multiple varieties and small batches.
