Description

technical field [0001] The invention relates to the field of steel strip thickness detection, more specifically, to a device for measuring the thickness of steel strips in the production process by using a distance sensor. Background technique [0002] Steel belt refers to the conveyor belt made of carbon steel. The steel belt can be used as the traction and movement construction of the belt conveyor, and it can also be used for bundling goods. A narrow and long steel plate required for mechanical or mechanical products. Steel strip, also known as strip steel, is generally supplied in coils, and has the advantages of high dimensional accuracy, good surface quality, convenience and processing, and material saving. At the same time, the steel strip can be directly rolled to form the basic structure of the shelf, and then spliced ​​into the entire shelf by bolts. .

AI Technical Summary

Problems solved by technology

[0003] In the basic construction of steel strip rolling shelves, the shelf factory generally obtains multiple coils of steel strips directly from the steel strip factory, and the thickness of the rolled steel strips is different. Therefore, the total length of two coils of steel strips of the same size is often due to the difference in thickness. They are also different. Often, the thickness of the steel strip will be greatly reduced if the thickness of the steel strip is increased a little. Since the purchase of the steel strip is usually priced by weighing, if the thickness of the steel strip is higher than the actual need, then the same price can be purchased. The length of the steel coil obtained cannot achieve the expected effect, resulting in low cost performance for purchase. Therefore, it is particularly necessary to detect the thickness of the steel strip before production.

Steel strips obtained from the manufacturer are generally packaged in bare packages. Due to transportation, loading and unloading, and storage, the outer surface is not suitable as a sample for inspection. Inspection methods can only be added during the production process to inspect the thickness of the steel strip; at the same time The storage limitations of the steel strip itself make it impossible to move at will. Therefore, it is very inconvenient to measure the thickness of the coiled steel strip in mass production.

[0004] At the same time, the surface of the coiled steel strip is not completely flat after unrolling, and the steel strip is often in a curved state, and the thickness of different positions of the same coiled steel strip is often not the same, so it is not convenient to directly detect ;The existing detection method is to manually open the rolled steel strip and then use a micrometer to measure one by one. The measurement is not only time-consuming and laborious, but also consumes a lot of manpower and material resources. At the same time, human factors are also a great factor that affects the measurement accuracy of the steel strip. The thickness of the steel strip may not be fully measured, but only deal with the thickness detection task of the steel strip according to one's own subjective assumptions, which has a great impact on the accuracy of the thickness detection of the steel strip

At the same time, during the whole process of steel strip thickness detection, the thickness detection data of the steel strip has been recorded manually, which is not only easy to make mistakes, but also difficult to carry out data classification and statistics, and the thickness data corresponding to the steel coil cannot be found when needed , has a great impact on production
