A system and method for monitoring vacuum leakage of VPL production line

Abstract

The invention relates to the field of glass processing equipment, in particular relates to a vacuum leak monitoring system on an automobile glass production line, and in particular relates to a VPL production line vacuum leak monitoring system and method. The system comprises a vacuum pump. The vacuum pump comprises an air inlet and an air outlet. The air outlet of the vacuum pump is provided with a vacuum leak monitoring device. The vacuum leak monitoring device comprises rotating fan blades and a photoelectric switch. The photoelectric switch comprises a transmitting end which can transmit an optical signal and a receiving end which can receive the optical signal. According to the system and method, which are provided by the invention, product quality problems which are may caused by possibly interrupted vacuum leak monitoring and instable monitoring data are avoided; the vacuum leak monitoring device comprises the rotating fan blades and the photoelectric switch, and can carry out real-time monitoring, recording, analyzing and tracing; vacuum volume catastrophe of a VPL production line in production in a short time can be avoided; incorrect operations are reduced; and the production efficiency of the VPL production line is improved.

Description

Technical field: [0001] The invention relates to the field of glass processing equipment, in particular to a vacuum leakage monitoring system on an automobile glass production line, in particular to a system and method for monitoring vacuum leakage in a VPL production line. Background technique: [0002] The laminated glass on the car, especially the front windshield, is generally composed of two glass substrates and an intermediate diaphragm. Automotive laminated glass generally needs to go through the VPL production line for initial pressure treatment after the laminating process. The initial pressure treatment is mainly used to remove more than 70% of the air between the glass substrate and the intermediate film, and make the glass substrate and the intermediate film The periphery of the film is sealed to prevent air and moisture from entering during subsequent processing, and finally the glass substrate and the intermediate film are initially bonded together. Usually, a...
