Film-coated assembly for industrial tablet computer manufacturing, including a chassis, the top and rear end of the chassis are continuously embedded with a film roll, the inside of the chassis undergoes screws and there is a constant arm, and the inside of the chassis undergoes a screw and there is no slippage. The sliding rail has a cutting knife continuously sliding on it, a telescopic arm is continuously passed through the screw in the chassis, a splint is continuously provided in the transmission of the telescopic arm, and a heater is not changed in the inner wall of one end of the chassis through a screw. The inner side of the heater is continuously driven with a torsion shaft, the torsion shaft experiences a screw without a heat conduction plate, the front end of the chassis undergoes a screw without a controller, the front end of the chassis is embedded with a survey window, and the industrial flat panel The film assembly for computer manufacturing has experienced the comparative sliding of multiple sets of sliders and slide rails, which facilitates the transportation of the thin film quiet board computer, and the assembly has undergone vacuum suction and is suitable for heating and baking purposes. The film has high results and can be effectively prevented from falling out. The layout is simple and easy to manipulate.
An industrial panel computer screen backlight power supply circuit, including a pre-clamping circuit and a post-regulating circuit. The pre-clamping circuit includes a voltage input terminal, a fourth Schottky diode, a DC/DC changer, a fourth inductor, The fifth Schottky diode and the power supply. The voltage input end is divided into the anode of the fourth Schottky diode and the sixth pin of the DC/DC converter. The sixth pin and the seventh pin of the DC/DC converter Continue, the sixth pin of the DC/DC converter is also continuous with one end of the fourth inductor, the other end of the fourth inductor continues with the anode of the fifth Schottky diode, the cathode of the fourth Schottky diode and the fifth Schottky The cathodes of the special diodes are continuous with the power supply; the post-stage regulator circuit includes a step-down regulator, a twenty-seventh capacitor, a sixth inductor and a second power supply. This book can reduce the difficulty of the power plan, the old cost, and the naivety of the new model.
