The electrical control system of the vacuum coating machine is divided into three main parts: control cabinet, transformer unit and operation console. The control components of all functions of the equipment, including programmable PLC, frequency converter, voltage regulating module, are installed in the control cabinet. The front of the control cabinet is equipped with resistance and ionization composite vacuum gauge, the heating ammeter of booster pump and diffusion pump, and the indicator light, alarm indicator light, and emergency stop switch of three-phase power supply.
The transformer unit is installed under the vacuum tank, and its output positive pole is directly connected with the corresponding evaporation electrode rod, and the output negative pole is connected with the evaporation negative pole after parallel connection.
The operation console is placed in front of the vacuum tank and below the observation window. The touch screen, operation control buttons, knobs or switches of various components are all located on the panel of the operation console.
The touch screen is located at the upper left of the operation panel. The winding system parameters, including the setting and data display of the tension of winding and unwinding, the winding diameter, the running speed of the machine, and the running indication of the vacuum system, are all carried out on the touch screen.
The upper right part of the operation panel is the heating power adjusting button of the evaporation source and the ammeter, which can adjust and display the power of each group of evaporation sources.
The lower part of the operation panel is the function control button or switch, including the main switch for controlling the power supply, the forward and backward movement of the winding car, the forward and backward movement of the swing arm, the forward and reverse rotation of the bending roll, the wire feeding switch and the speed, the cover switch, the control mode selection of the system operation, etc.
The electrical control core of HD1500-12 high vacuum roll coating machine is programmable PLC and its expansion module, supplemented by vacuum gauge, encoder, proximity switch and Hall switch to complete the detection and control functions.
HD1500-12 high vacuum winding coating machine adopts three-phase five wire power input, and roll bending motor, evaporation transformer, Hall switch and control circuit adopt 220V; The vacuum pump motor, main roll motor, winding motor, winding car motor, hydraulic station motor and wire feeding motor adopt 380V three-phase power supply; The PLC input circuit, encoder and proximity switch use DC 24V. The power supply capacity is about 180kw.
The user should set up a power switch box for the machine separately near the machine, and provide the power cord to connect the power supply to the terminals of the machine code R, S, T, N.
