Problems solved by technology

[0002] Flatness measurement refers to the amount of variation between the measured actual surface and its ideal plane. At present, it is necessary to measure flatness accurately and quickly in many occasions, but most of the existing detection methods are based on manual visual inspection. Large errors make it difficult to achieve high product consistency, and manual labor is prone to visual fatigue, resulting in a low pass rate of the product, affecting subsequent use, and low efficiency

Embodiment Construction

[0018] The present invention will be described in further detail below.

[0019] A fast measuring method for flatness, comprising the steps of:

[0020] Step 1, placing the sample to be tested on a horizontal platform with the tested side facing down;

[0021] Step 2, multiple laser displacement sensors are installed inside the horizontal platform, and measuring holes are set on the platform;

[0022] Step 3, turn on the laser displacement sensor, and at the same time move the sample to be tested, and use the laser displacement sensor to scan multiple positions on the surface of the sample;

[0023] Step 4, the laser displacement sensor automatically writes the measurement results into the acquisition program, and extracts the maximum and minimum values ​​to obtain flatness information;

[0024] Step five, automatically fill in the measurement results into the output template, and print the flatness test report.

[0025] Preferably, the horizontal platform in step 1 is a ma...

Abstract

The invention discloses a rapid planeness measuring method. The rapid planeness measuring method comprises the following steps that firstly, a measured sample is placed on a horizontal table facet, and the measured surface of the measured sample faces downwards; secondly, a plurality of laser displacement sensors are mounted inside the horizontal table facet, and a measuring hole is formed in thetable facet; thirdly, the laser displacement sensors are started, meanwhile, the measured sample can be moved, and a plurality of positions on the surface of the sample are scanned through the laser displacement sensors; fourthly, the measuring result is automatically written into a collecting program by the laser displacement sensors, the maximum value and the minimum value are extracted, and thus planeness information is obtained; and fifthly, an output template is automatically filled with the measuring result, and a planeness testing report is printed. According to the rapid planeness measuring method, the planeness can be measured rapidly and accurately, and consistency is high.

Description

technical field [0001] The invention relates to the detection field, in particular to a fast flatness measurement method. Background technique [0002] Flatness measurement refers to the amount of variation between the measured actual surface and its ideal plane. At present, it is necessary to measure flatness accurately and quickly in many occasions, but most of the existing detection methods are based on manual visual inspection. Large errors make it difficult to achieve high product consistency, and manual labor is prone to visual fatigue, resulting in a low pass rate of the product, affecting subsequent use, and low efficiency. Contents of the invention [0003] Purpose of the invention: In order to solve the above problems, the present invention provides a fast measurement method for flatness. [0004] Technical solutions: [0005] A fast measuring method for flatness, comprising the steps of: [0006] Step 1, placing the sample to be tested on a horizontal platfor...
