Control system and method of inhomogeneous film layer product film coating equipment

Abstract

The invention discloses a coating control system of an inhomogeneous film layer product. The control system comprises an upper computer, a PLC control host, an information acquisition device, a motorservo controller and a sputtering cathode power supply controller; the information acquisition device is used for detecting positions of a glass substrate on conveying roller ways, and temperature andair pressure information in process cavities, and the PLC control host is used for receiving detection information sent through the information acquisition device; the motor servo controller and thesputtering cathode power supply controller are controlled to work according to the detection information; and the motor servo controller is used for sending control signals to motors and controlling the motors to rotate according to different set speed curves. According to the coating control system of the inhomogeneous film layer product, the motor servo controller controls the motors to rotate according to the set motor rotating speed curves so that n conveying rollers corresponding to each layer of films can be independently adjusted and controlled, then the speed of the glass substrate under the corresponding sputtering cathode can be adjusted, then the thickness of a coated film layer can be changed controllably, and the effect that a coated film of the inhomogeneous film layer product can be continuously produced in a large scale is realized.

Description

technical field [0001] The invention relates to the technical field of glass coating production, in particular to a control system and method for coating equipment for non-uniform film layer products. Background technique [0002] At present, the appearance of electronic products has become an important factor for the success of a product, which also includes the appearance and color design of the product. Taking the color design of the back panel of the mobile phone casing as an example, most of the mobile phone casing backplanes can only have one color at the same time at the same time, and the color is evenly distributed. This type of design facilitates large-scale continuous production of mobile phone backplanes to meet the market's demand for quantity. However, this design also has limitations. The color on the back panel of the mobile phone is relatively monotonous, and the homogeneity is serious, lacking freshness. The current large-area magnetron sputtering continu...

Problems solved by technology

In a section of the process chamber, only one motor is used to drive all the roller tables. For the uniformity of the coating, the transmission speed is maximized under all the cathodes. The process design results in a single color of the coating and uniform color distribution.
