Description

Technical Field

[0001] The utility model belongs to the technical field of thickness measurement of metal sheets, in particular to a high-precision automatic thickness measuring device for magnesium alloy sheets. Background Art

[0002] With the continuous development of science and technology, people in the 3C electronics field are no longer solely focused on performance, but are also beginning to pay attention to its lightweight application. Currently, magnesium alloys are light weight, high strength, good thermal conductivity and electrical conductivity, and have excellent electromagnetic shielding and good machinability, making them an ideal material for 3C electronic products.

[0003] However, the magnesium alloy preparation process is complicated, requiring multiple rolling, heat treatment, shearing, grinding and other processes, resulting in low production efficiency. The consistency of sheet thickness during the production process is difficult to ensure, requiring various inspection and control measures. However, contact inspections will leave scratches on the sheet, resulting in a low product qualification rate and high production costs. This greatly limits the promotion and application of magnesium alloy sheets in the industry. Magnesium alloy processing technology issues have become a roadblock to improving the quality and reducing costs of magnesium alloys and expanding their applications, but the market demand for magnesium alloy sheets has not diminished.

[0004] Currently, magnesium alloy sheet thickness is primarily controlled through manual micrometer point measurement to ensure the final thickness tolerance. The main issues are that contact measurement can scratch the sheet; manual point measurement is inefficient; and measurement results are inaccurate due to human interference. Utility Model Content
