Embodiment Construction

[0034] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0035] Image-based grinding method for crucible defects, its application and CNC grinding robot, such as figure 1 Shown, described processing method comprises the steps:

[0036] (1) Manually mark the defect positions on the quartz ceramic crucible to be processed and the number of times the corresponding defect positions need to be polished.

[0037] (2) Establish an image model of the appearance of the quartz ceramic crucible to be processed in the numerical control system: use an industrial camera to take pictures of each surface of the quartz ceramic crucible to be processed, including the outer side, inner side and bottom surface, and then transmit the image to PC side.

[0038] (3) Perform preprocessing, noise filtering and grayscale operations on the image in sequence and generate a grayscale...

Abstract

The present invention relates to the processing field of quartz ceramic crucibles, in particular to an image-based processing method for grinding defects in a crucible and a processing system using the same. The processing method includes the following steps: (1) manually marking the crucible; (2) establishing the appearance of the crucible Image model; (3) Generate a grayscale histogram; (4) Generate a binary image; (5) Set a single pixel value to 0; (6) Determine the start position and end position; (7) Collect the intersection area (8) Obtain the number set and area set; (9) Match the number set and area set; (10) Normalize the number and area; (11) Correct the number in the defect area Identify the position of the defect area and the number of grinding times; (12) generate the processing trajectory file. The method provides necessary processing parameters and generates a processing trajectory file when the robot grinds the crucible, so that the grinding robot can automatically grind the crucible.

Description

technical field [0001] The invention relates to the processing field of quartz ceramic crucibles, in particular to a method for using machine vision to identify defects of quartz ceramic crucibles and generate processing trajectory files and a processing system using the same. Background technique [0002] The full name of quartz ceramic crucible is quartz glass ceramic crucible. It is a ceramic crucible made of quartz glass as raw material, mostly square. Fine fused silica ceramic material has the characteristics of fine structure, low thermal conductivity, small thermal expansion coefficient, high dimensional accuracy, no deformation at high temperature, good thermal shock stability, good electrical performance, and good chemical corrosion resistance, so it is widely used in the glass deep processing industry. , metallurgical industry, electronics industry, chemical industry, aerospace and other fields are widely used. [0003] In recent years, with the continuous attenti...
