Description

Technical Field

[0001] The invention relates to the field of coated sand casting, and in particular to a casting coated sand quality robot and a control method thereof. Background Art

[0002] The foundry industry occupies an important position in the national economy. In the production process of foundry sand, the accuracy of the test results of the finished product is crucial. A slight deviation in the test data will lead to the appearance of substandard products and cause great waste, thereby increasing production costs. Automatic detection of coated sand for casting improves the detection efficiency and accuracy, avoids detection deviations caused by operational errors during the detection process due to human factors, reduces personnel settings, and reduces the labor intensity of operators. At the same time, the test data is saved in the computer, which can be displayed as a curve and automatically calculated. With the advancement of science and technology and the continuous improvement of production technology, how to improve the detection accuracy and efficiency of foundry sand has become a key issue that needs to be urgently solved in the industry.
