Manufacturing method of pressure sensor for scraper test platform of painted sheet metal parts

Abstract

The invention discloses a method for manufacturing a paint sheet metal scraper test platform. The method comprises steps that S1, a film inductor is selected as a pressure sensor; S2, high-resistancecarbon paste is printed on an upper circuit PET substrate layer to form a high-resistance carbon film layer; S3, anisotropic conductive adhesive is printed on the high-resistance carbon film layer toform an anisotropic conductive adhesive film layer to obtain an upper circuit layer; S4, a high-conductivity silver film layer is printed on a lower circuit PET substrate layer; S5, an insulation protection film layer is printed on the surface of the high-conductivity silver film layer to obtain a lower circuit layer; S6, PET substrate single-sided adhesive with thickness of 0.3 mm is pasted on anon-printing surface of the upper circuit PET substrate layer; step7, PET substrate double-sided adhesive with thickness of 0.23 mm is pasted on a printing surface of the insulation protection film layer; and S8, the upper and lower circuit layers are bonded together through PET substrate double-sided adhesive. The method is advantaged in that working stability and reliability can be guaranteed through the processing method of each layer of the film inductor.

Description

technical field [0001] The invention relates to a method for manufacturing a scraper test platform for 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 in...
