Embodiment 1

[0036] The control system of the scraper test platform for painted sheet metal parts in this embodiment includes a pressure sensor and a control circuit.

[0037] The pressure sensor is a thin-film sensor, and its cross-sectional schematic diagram is shown in figure 1, for the convenience of understanding, the figure does not follow the thickness ratio of each layer. From top to bottom, the thin film sensor is PET substrate single-sided adhesive 4, upper line PET substrate layer 1, high resistance carbon film layer 2, anisotropic conductive adhesive film layer 3, blue upper protective film 9, PET substrate layer Material double-sided adhesive tape 8, blue lower protective film 10, insulating protective film layer 7, high-conductivity silver film layer 6, lower line PET substrate layer 5. Upper line PET substrate layer 1, high resistance carbon film layer 2, anisotropic conductive adhesive film layer 3 constitute the upper circuit layer; insulating protective film layer 7, hig...

Abstract

The invention discloses a control system for a paint sheet metal scraper plate test platform. The control system is composed of a pressure sensor and a control circuit. The pressure sensor is a thin-film inductor and has seven groups of resistor output signals. Input terminals of seven groups of comparison amplifier circuit modules are connected with the seven groups of resistor output signals andoutput terminals of the seven groups of comparison amplifier circuit modules are connected with an input terminal of a single-chip microcomputer module; the output terminal of an RS485 transceiver module is connected to the input terminal of a three-channel digital isolator module; the output terminal of the three-channel digital isolator module is connected to the input terminal of the a single-chip microcomputer module; the output terminal of the single-chip microcomputer module is connected with the input terminal of a driving adjusting circuit module; and the output terminal of the driving adjusting circuit module is connected with a paint sheet metal scraper plate motor. According to the invention, the scraper plate tested by the platform can be applied to plaster and scraping process 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 control system of 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 include t...
