Embodiment 1

[0044] like figure 2 As shown, the present invention provides a two-dimensional detection method for microarray coverslips based on a laser displacement sensor, comprising the following steps:

[0045] S1, set the laser displacement sensor 1 to be perpendicular to the front surface of the microarray cover sheet 10; in fact, the laser displacement sensor 1 may not be perpendicular to the front surface of the microarray cover sheet 10, and its main purpose is to keep the laser displacement sensor 1 and the microarray cover sheet 10. 10, the bending deformation detection of the microarray cover sheet 10 can be realized by detecting the change of the distance. In this embodiment, the laser displacement sensor 1 is set perpendicular to the front surface of the microarray cover sheet 10, so that the obtained data can be processed better.

[0046] S2, move the laser displacement sensor 1 along the horizontal direction and the vertical direction of each convex surface of the microar...

Embodiment 2

[0079] like image 3 As shown, the present embodiment provides a two-dimensional detection device for microarray coverslips based on a laser displacement sensor, including:

[0080] Laser displacement sensor 1; the laser displacement sensor 1 is perpendicular to the front surface of the microarray cover sheet 10;

[0081] Robotic arm; the robotic arm is used to move the laser displacement sensor 1 along the horizontal and vertical directions of each convex surface of the microarray cover sheet 10 to measure several data;

[0082] Data processing device 2; the data processing device 2 is connected to the laser displacement sensor 1, and is used to calculate the average value and coefficient of variation of each convex surface in the horizontal direction and the vertical direction by using several measured data, based on the calculated average value and The coefficient of variation determines whether the microarray cover sheet 10 is bent or deformed.

Abstract

The invention discloses a microarray cover plate two-dimensional detection method and device based on a laser displacement sensor. The detection method comprises the following steps: S1, enabling thelaser displacement sensor to be vertical to a frontage of a microarray cover plate; S2, moving the laser displacement sensor along horizontal directions and vertical directions of various convex sidesof the microarray cover plate to measure multiple data; and S3, computing average values and variable coefficients of each convex side on the horizontal direction and the vertical direction by utilizing the multiple measured data, and judging whether the microarray cover plate is bent and deformed based on the computed average values and variable coefficients. By adopting the laser displacement sensor, the measurement data is more accurate and reliable, the measurement precision is higher, the condition that the minimum distance is used for replacing the whole convex side to the work table inthe traditional method is avoided, and the practicability is provided; a measurement object is analyzed by adopting the two-dimensional detection method, so that a measurement result is more persuasive, and whether each convex side of the microarray cover plate is bent and deformed can be really reflected.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a two-dimensional detection method and device for a microarray cover sheet based on a laser displacement sensor. Background technique [0002] In today's era, with the advancement of medicine and the development of the medical industry, microarray coverslips are widely used in medical detection and screening, providing a convenient diagnostic method for the medical field and medical research, widely serving and applying to human beings, and contributing to human society. made important contributions to the progress and development of So do the microarray coverslips produced meet medical standards? How to test it? In this case, how to detect whether the microarray coverslip is qualified or not becomes the key. [0003] In the existing microarray cover slip detection method, the distance between each convex surface and the work surface is measured from the side of the co...
