Abstract

The invention discloses a device for the real-time online measurement of glass thickness in the technology of glass thinning, and the device comprises a reference probe and an induction probe. The reference probe comprises a reference probe supporting bushing, an eddy current reference seat, a reference probe laser range-finding sensor, and a reference probe buffering spring. The induction probe comprises an induction probe supporting bushing, an eddy current sensor, an induction probe laser range finding sensor, and an induction probe buffering spring. Two sensors respectively detect the spacing changes caused by the compressed deformation of the reference probe buffering spring and the induction probe buffering spring, and achieve the measurement of thickness. The invention also discloses a corresponding measurement system, a corresponding measurement method, and an application. The device which achieves the automatic measurement through various types of sensors can avoid the impact from the corrosive solution in the technologies of glass thinning and secondary strengthening, and achieves the real-time online obtaining of the accurate measurement information.

Description

technical field [0001] The invention belongs to the technical field of thickness measurement, and in particular relates to a device and method for measuring the thickness of ultra-thin glass, especially suitable for automatic real-time measurement of glass thickness in the secondary strengthening and thinning process of ultra-thin glass. Background technique [0002] The glass used in mobile phones, tablet computers, LCD TVs and other equipment often requires the process of thinning and secondary strengthening of raw glass, so as to obtain glass with a thinner thickness (as thin as 0.11mm) and higher strength. Only the thinned glass will be used as the screen glass of electronic equipment. [0003] In the current glass thinning process, a large piece of glass is usually soaked in some kind of electrolyte solution, and then the electrolyte solution is used to produce a chemical reaction with the glass to continuously corrode the outer layer of the glass, thereby realizing the...
