Abstract

The embodiment of the invention discloses an automatic thickness measuring machine for a touch display screen. The automatic thickness measuring machine comprises an overturning conveying platform, afixed conveying platform, a displacement adjusting mechanism and a man-machine interaction device. The overturning conveying platform and the fixed conveying platform are both installed on a rack, thedisplacement adjusting mechanism is arranged between the fixed conveying platform and the overturning conveying platform and is installed on a displacement adjusting mechanism support, and the displacement adjusting mechanism support is fixed to the rack. According to the invention, the thickness of a touch panel can be measured at fixed points, three points can be measured at one time, and the online mobile real-time measurement also can be realized. The automatic thickness measuring machine has the advantages of simple operation, high measurement precision and stable transmission, the measurement data is automatically stored in the man-machine interaction device, and the measurement data can be copied and directly printed by a USB flash disk, so that the measurement efficiency and accuracy are significantly improved, the reject ratio caused by personnel contact measurement is solved, the product quality is improved, and the manpower and the enterprise production cost are saved.

Description

technical field [0001] The invention relates to the field of display panel measurement, in particular to an automatic thickness measuring machine for a touch screen display. Background technique [0002] The thinning of the display panel mainly uses chemical etching (main method) and physical grinding (auxiliary method) to thin the panel module and display glass. Today, with the development of high-quality and thinner touch display panels, it is necessary to thin the touch panel from more than 0.8mm to the 0.4-0.3mm commonly used in the industry, or even thinner. The main purpose of thinning the panel is to make the panel thinner and lighter, to provide clearer and brighter picture quality, and to increase the space for mobile phone components. [0003] No matter how big the panel is, it needs to be cut from a whole panel. The higher the algebra of the production line, the larger the size of the substrate it produces. The traditional method of measuring thickness is mostly...
