Problems solved by technology

[0003] The indentation measurement method used by existing automation equipment is based on pixel-level image processing. This method often fails to meet the requirements for indentations with a size of only a few microns.
At the same time, when using the camera of automated equipment to shoot, it is often necessary to manually judge whether the current focus is in focus through the eyepiece, and adjust the position of the stage by manual operation so that the indentation is on the focus plane of the camera. This method cumbersome and inefficient

Embodiment 1

[0079] Such as figure 1 and figure 2 As mentioned above, this embodiment discloses a fully automatic indentation measurement device, including an electric stage, an image capture module and an operation processing module; the electric stage and the image capture module are all connected to the operation processing module;

[0080] The electric stage is used to place (carry) the object to be measured; and receive instructions from the computing processing module, and complete the functions of translation and lifting through the motor drive, so that the object to be measured on it is in the field of view of the image capture module within the range and keep in focus;

[0081] The image capture module is used to acquire the image of the object to be measured placed on the electric stage, and transmit the image to the operation processing module;

[0082] The operation processing module is used to acquire and process the images acquired by the image capture module, perform the ...

Embodiment 2

[0092] Such as image 3 As shown, this embodiment discloses a fully automatic indentation measurement method, using the fully automatic indentation measurement device described in Example 1 to perform indentation measurement, including the following steps:

[0093] Step 1. The image capture module acquires the surface image of the object to be measured placed on the motorized stage, and transmits it to the operation processing module;

[0094] Step 2. Based on the image acquired by the image capture module, the operation processing module controls the horizontal movement of the motorized stage so that the surface of the object to be measured is in the field of view of the image capture module, and controls the lifting of the motorized stage so that the surface of the object to be measured is in the image The focal plane of the capture module;

[0095] The operation processing module controls the lifting of the motorized stage, so that the surface of the object to be measured ...

Abstract

The invention discloses a full-automatic indentation measuring device and method. The device comprises an electric objective table, an image capturing module and an operation processing module. The electric objective table and the image capture module are connected with the operation processing module; the electric objective table is used for placing an object to be measured; the image capture module is used for acquiring an image of a to-be-measured object placed on the electric objective table and transmitting the image to the operation processing module; and the operation processing moduleis used for processing the image acquired by the image capture module, controlling the electric objective table to horizontally move so as to enable the surface of the object to be measured to be located in the field of view of the image capture module, controlling the electric objective table to lift so as to enable the surface of the object to be measured to be located on the focusing surface ofthe image capture module, and solving surface indentation data of the object to be measured. The device is simple and convenient to use and operate and high in measurement precision.

Description

technical field [0001] The invention relates to a hardness indentation measuring device and method, in particular to an automatic indentation measuring device and method. Background technique [0002] In the Brinell and Vickers hardness tests, in order to detect the hardness of the material to be tested, it is necessary to use the corresponding indenter according to the national standard, apply a specified pressure on the surface of the material to be tested, and then calculate the indentation by measuring the diagonal length of the indentation. Measure the hardness of the material. In most measurements, the diagonal length of the indentation on the surface of the material being tested is measured in microns. The method of manually adjusting the scale plate through the microscope to align the edge of the indentation is more complicated and difficult to eliminate measurement errors. At the same time, in the process of measuring the same hardness material for many times, it ...
