Abstract
Disclosed is a polytetrafluoroethylene sealing gasket thickness nondestructive monitoring system based on a single chip processor and ultrasonic. The system is capable of setting the threshold of the qualified thickness of a polytetrafluoroethylene sealing gasket through an external key; an ultrasonic monitoring device monitors the distance parameters between the gasket and a device body in a non-contact manner; data are transmitted to the single chip processor through a filter, a display screen of the single chip processor displays the thickness value, the data reference is provided to an operator, and the system performs sound and light alarm to prompt after the thickness of the monitored gasket exceeds the set qualified thickness threshold.
Description
Art
Patent of the present invention is a kind of polytetrafluoroethylene sealing gasket sheet thickness non-destructive monitoring system, is applied to polytetrafluoroethylene sealing gasket sheet production monitoring.
Background technology
Teflon has a variety of application mode as encapsulant.Because itself has highly corrosion resistant, stable physical property, high-low temperature resistant, has achieved its good sealing property, has all been widely used at oil, chemical industry, pharmacy, electric power, steel industry.The medium be suitable for comprises nearly all chemical industry composition such as water, oil, acid solution, aqueous slkali.Teflon gasket is durable in use, and sealing property is reliable; Teflon itself has best corrosion-resistant with not aging, has good creep resistant and resistance to cold flow properties after special processing; Long-term safety can use in very wide temperature range; Soft easily cutting, cuts out by mechanical or manual, and be convenient to install, the increasing extent of its application is extensive.
Current polytetrafluoroethylene sealing gasket mo(u)ldenpress stamping press is due to opened loop control, may stable due to stamping press, cause the in uneven thickness of polytetrafluoroethylene sealing gasket sheet, gasket seal non-destructive monitoring system achieves monitors its thickness under the state of not contact pins.
Summary of the invention
In order to improve monitoring polytetrafluoroethylene sealing gasket sheet thickness automaticity and do not damage gasket seal shaping under, the present invention proposes a kind of based on single-chip microcomputer and hyperacoustic polytetrafluoroethylene sealing gasket sheet thickness non-destructive monitoring system, this system is by the threshold value of the qualified thickness of external key setting polytetrafluoroethylene sealing gasket sheet, the contactless monitoring patch of ultrasonic monitor device and the distance parameter between it, monolithic is transferred data to after filtering after device, and the LCDs display one-tenth-value thickness 1/10 by connecting single-chip microcomputer, for operator provides data reference, after the spacer thickness of monitoring has exceeded the qualified thickness threshold value of setting, system sends sound and light alarm signal and points out.
The technical solution adopted in the present invention is: set up a kind of polytetrafluoroethylene sealing gasket sheet thickness non-destructive monitoring system based on Atmega48 single-chip microcomputer, by the threshold value of the qualified thickness of external key setting polytetrafluoroethylene sealing gasket sheet, the contactless monitoring patch of ultrasonic monitor device on setting-up piece production travelling belt and the distance parameter between it, monolithic is transferred data to after filtering after device, the thickness of gasket seal is drawn after single-chip data process, ultrasonic monitor device is h1 to the distance of travelling belt, monitoring layback data h2, then gasket seal height h=h1-h2, and show one-tenth-value thickness 1/10 by LCDs, for operator provides data reference, after the spacer thickness of monitoring has exceeded the qualified thickness threshold value of setting, system sends sound and light alarm signal and points out.
Beneficial effect of the present invention destroy polytetrafluoroethylene sealing gasket sheet shaping under, contactless monitors the thickness data of gasket seal.
