Abstract

The invention discloses a producing and preparing technology of a strain gauge. The preparing technology comprises the following steps of: elastomer machining, elastomer crude polishing, sand blasting, fine polishing, scribing, ultrasonic cleaning, surface mounting, stress testing, solidification, chip detection, welding spot processing, circuit board pasting, bridging wire processing, overload testing, surface glue coating, preliminary performance detection, trimming of four corners, zero point compensation, glue sealing, electric aging, total adjustment, and cleaning and packaging. The producing and preparing technology of the strain gauge has the advantages that the e strain gauge produced by the producing and preparing technology is high in resolution and is capable of measuring minimal strain which can be accurate to 0.5-2 micro-stain; the size is small, and the weight is light; the error is relatively small, reliable working can be achieved just by taking suitable measures; the producing and preparing technology has all advantages of electric measurement, for example, the measurement result can be conveniently sent, recorded and processed; the cost is low, the variety is numerous, selection and a large amount of usage are facilitated; and the yield rate is improved to 97.5%.

Description

technical field [0001] The invention belongs to the technical field of strain gauges, and in particular relates to a strain gauge production process. Background technique [0002] Resistance strain gauge is a measurement tool that can measure changes in electrical signals on engineering components. The grid and strain gauge base material are the most commonly used processes for processing strain gauges. The adhesive layer formed by the adhesive must reliably and accurately transmit the strain generated by the test piece or elastic element to the sensitive grid of the strain gauge. Sensor measurements have a direct impact. As we all know, the final quality of the strain gauge depends on the stability of the adhesive and the manufacturing process. In the actual production process, due to various reasons such as the glue used, the process method, and the detection technology, the product scrap rate in actual production is relatively high. High, and the strain output accuracy ...
