Pressure sensor for scraper test platform for painted sheet metal parts

Abstract

The invention discloses a pressure sensor for a paint sheet metal scraper plate test platform. The pressure sensor is a thin-film sensor comprising a PET substrate single-sided adhesive, an upper-linePET substrate layer, a high-resistance carbon film layer, an anisotropic conductive film layer, a PET substrate double-sided adhesive, an insulating protective film layer, a high-conductivity silverfilm layer, and a lower-line PET substrate layer that arranged successively from top to bottom. A silver line pattern is printed on the high-conductivity silver film layer and is divided to two parallel detection regions; seven consistent patterns as stress detection regions are arranged in each detection region in a horizontal direction; the silver line pattern in one detection region is formed by thin lines; and the silver line pattern in the other detection region is formed by thick lines. According to the invention, the thin-film sensor is used as a pressure sensor assembly for the paint sheet metal scraper plate test platform. The scraper plate tested by the platform can be applied to plaster and scraping flows of a large-area paint sheet metal part; the flatness of the large-area paint sheet metal part is increased substantially; and the work efficiency is improved.

Description

technical field [0001] The invention relates to a pressure sensor for a scraper test platform of painted sheet metal parts. Background technique [0002] The repair process of large-area painted sheet metal parts mainly includes the correction of lines, planes and arcs, including: filling gaps, grinding the shell, spraying paint, drying, waxing and polishing. Among them, the correction of flatness is the most critical step. [0003] The traditional repair process of painted sheet metal parts is simple, and basically all rely on manual labor and experience. In the repair process of sheet metal parts, the biggest problem is the flatness correction of painted sheet metal parts. Poor flatness will lead to difficult control of paint thickness consistency, uneven color and contour changes. Solving this problem is a guarantee The key to the quality of paint workmanship. [0004] At present, the commonly used scraper detection methods for painted sheet metal parts mainly include ...
