Problems solved by technology

In the later stage of the production of strain gauge products, it is necessary to separate the individual strain gauge products from the whole plate, and test the individual strain gauge products, and finally sort them according to the test results. The current existing method is to manually use scissors along the product The outer frame trims a single product, and manually detects and sorts a single product. This manual sorting method not only has low production efficiency, high labor intensity, high production cost, and is prone to errors, which is not conducive to the stability of product quality. sex control

Description

technical field [0001] The invention belongs to the technical field of resistive strain gauge production, and in particular relates to an automatic sorting device and method for large array resistive strain gauges. Background technique [0002] Resistive strain gauge is the key component of experimental stress analysis, test measurement technology, automatic detection and control technology, and weighing or force sensor. It has small size, small creep, good fatigue resistance and good stability, etc. Features, widely used in water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, military industry, petrochemical and weighing instruments and other industries. Resistive strain gauges are mainly pasted on the surface of the elastic body. The slight deformation (elongation or shortening) of the surface of the elastic body after being loaded causes the strain gauge pasted on its surface to also deform. After the resistance...
