Abstract

The invention relates to an architectural glass coating sputtering chamber transmission speed automatic control system and an execution method. The automatic control system comprises a conveying mechanism, a conveying mechanism controller, a plurality of target positions, a target position power supply, a PLC control system, a field bus, and a plurality of target position data storage units; the PLC control system is connected with the conveying mechanism controller and the target position power supply through the field bus; each target position data storage unit is used for storing starting position information of a target position, tail end position information of the target position, power supply state information of the target position and speed mark information; and the PLC control system is used for calculating real-time position data of the glass in the sputtering chamber and controlling the conveying mechanism to adjust the transmission speed of the glass in the sputtering chamber according to a calculation result and a target position power supply starting state. According to the architectural glass coating sputtering chamber transmission speed automatic control system, coating parameter adjustment can be simpler and more convenient, the parameter adjustment time is shortened, the parameter adjustment efficiency is improved, manual adjustment is not needed, and labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to an automatic control system and execution method for the transmission speed of an architectural glass coating sputtering chamber. Background technique [0002] Vacuum magnetron sputtering coated architectural glass is a glass product that uses the principle of vacuum magnetron sputtering to coat one or more layers of metal, alloy or metal compound films on the glass surface to change the optical properties of the glass and meet certain specific requirements. Architectural coated glass is widely used because of its good thermal insulation performance and optical performance. [0003] In order to achieve specific optical and thermal insulation properties, it is necessary to adjust the film system parameters to achieve specific optical and emissivity parameters. This process is also called sample adjustment. In the sample adjustment process of architectural coated glass, i...

Problems solved by technology

In the sample adjustment process of architectural coated glass, it is necessary to adjust the transmission speed of the sputtering chamber to reduce the sample adjustment time. The existing architectural glass production line requires operators to pay close attention to the position of the glass on the production line. If the glass is in a non-sputtering position, manual adjustment The speed makes the glass accelerate through this position, and then manually return to the predetermined sputtering speed after reaching the sputtering position. The adjustment process is cumbersome and not user-friendly. The operator always pays attention to the position of the glass in the sputtering chamber, and manual judgment and adjustment of the sputtering are required. Chamber transmission speed; process debugging personnel have high labor intensity, low production efficiency, and prone to errors; long sample adjustment time and low sample adjustment efficiency
