Equipment for detecting tensile property of thermistor by utilizing polishing characteristics

Abstract

The invention relates to the technical field of thermistor pin detection, and further discloses equipment for detecting the tensile property of the thermistor by utilizing the polishing characteristics. The equipment comprises a shell, and an adsorption tank is fixedly connected to the interior of the shell; the bottom of the adsorption tank is movably connected with a millstone; a limiting bag isfixedly connected into the adsorption tank; the surface of the adsorption groove is movably connected with a spring rod; an extension spring is movably connected to the top of the adsorption groove,a supporting plate is movably connected to the interior of the extension spring, an extrusion rod is slidably connected to the surface of the supporting plate, a detection cover is movably connected to the end, away from the supporting plate, of the extrusion rod, rollers are movably connected to the interior of the detection cover, and buffer springs are movably connected to the surfaces of the rollers. The extension springs located on the lower portion move downwards, so that the symmetrical rollers get close to each other and clamp the pins to move downwards, the surfaces of the pins are unqualified if the pins are snapped at the moment, otherwise the surfaces of the pins are qualified, and therefore the effect of gradually detecting the anti-stretching capacity of the pins through thepin grinding working characteristics is achieved.

Description

Technical field [0001] The invention relates to the technical field of thermistor pin detection, in particular to a device for detecting the thermistor tensile resistance by using polishing characteristics. Background technique [0002] Thermistor is a type of sensitive components, according to the temperature coefficient is divided into positive temperature coefficient thermistor and negative temperature coefficient thermistor; the typical characteristics of thermistor is sensitive to temperature, performance under different temperatures Different resistance values; due to the particularity of the thermistor work, and the pins used need to be tested for tensile ability after the production is completed. [0003] Existing thermistor tensile capacity testing often adopts the method of sampling and manual testing. Although this method can ensure the quality of a batch of pins, there will also be some fish that slip through the net; it is damaged, that is, the pins are bent. Irregula...

Problems solved by technology

[0003] Existing testing of the tensile capacity of thermistors often adopts the method of sampling and artificial detection. Although this method can ensure the quality of a batch of pins, some fish will still slip through the net; if it is damaged, that is, the pins are bent Irregular and not straight, which affects the later use and installation effect, so a kind of testing equipment for thermistor tensile resistance using grinding characteristics came into being
