Intelligent film pasting device with power amplification circuit

Abstract

The invention discloses an intelligent film pasting device with a power amplification circuit. The intelligent film pasting device comprises a shell, a pressurization device and a press plate. The pressurization device is connected with the shell through a pipeline. An opening is formed in the side wall of the shell. The press plate is connected with the shell through the opening. A pressure sensor is arranged on the press plate. A signal of the pressure sensor passes through a sampling circuit, a filtering circuit and the power amplification circuit and then is transmitted to a single-chip microcomputer. The single-chip microcomputer controls work of the pressurization device according to the received signal. The power amplification circuit comprises an operational amplifier A1, an operational amplifier A2, an operational amplifier A3, a triode T1 and a triode T2. The inverted input end of the operational amplifier A1 is connected with the output end of the operational amplifier A1. The beneficial effects of high efficiency and quality are achieved.
