Problems solved by technology

[0003] However, this scheme has the following problems: using the data of each support point to replace all the measurement data of the entire measured surface, there is a large measurement error; the measurement process needs to be measured in sections according to the length of the bridge plate, which takes a long time and must ensure that Move along a straight line, otherwise there will be a large error

Abstract

The invention provides a full-automatic panel planeness detection device which comprises a measurement component and a driving component. The measurement component comprises polished shafts and a reflector installation base. The driving component comprises a stepping motor, a stepping motor controller, a bearing pedestal, a bearing shaft, a synchronous pulley and the like. The measurement polished shafts are attached to the measured face all the time by separating the measurement component from the driving component, and therefore measurement reliability and data independence are greatly improved. The full-automatic panel planeness detection device is used in cooperation with a photoelectric auto-collimator for detection to read measured data, and has the advantages of facilitating detection, being rapid in detection, high in accuracy and high in universality and the like.

Description

technical field [0001] The invention relates to a fully automatic flatness detection device for a flat plate. Background technique [0002] The flat plate is mainly used to check the flatness of large planes such as large machine tools, and is a kind of measuring tool for industrial use. With the gradual increase of flat panel manufacturers, the current testing volume of flat panels has greatly increased, which has become an important testing content in the testing industry. The flatness calibration of the flat panel is a standard determination of the flatness of the flat panel, so the result of the verification is very important, and it is also a guarantee for the flatness of the calibrated plane used in the flat panel. At present, the general method for flatness of flat panels is: according to the technical requirements for flatness measurement of flat working surfaces in the "JJF117-2005 Verification Regulations for Flat Panels", the flatness of flatness is measured by t...
