Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for steel strip production, and in particular to a special inspection tool for the assembly accuracy of pultruded composite steel strips. Background Technology

[0002] Steel strips are crucial components for limiting the battery packs of electric vehicles. Pultruded composites of steel strips are semi-finished products in the finished steel strip manufacturing process. The process involves cutting steel strips to a fixed length, punching bolt holes at both ends, attaching TC composite tape, heat-shrink tubing, and baking the strips. Then, grooved pultruded supports are glued onto the surface of the steel strip to form the pultruded composite. Subsequent processes require attaching foam to the surface of the pultruded composite. In existing technologies, the assembly accuracy of the grooved pultruded supports is not checked when the pultruded composite is formed by gluing them onto the surface of the steel strip. Instead, the finished product undergoes a one-time factory inspection, which results in the complete scrapping of any product that fails the inspection. This leads to a significant waste of materials, processing time, and labor costs used in all the preceding processes. Utility Model Content
