Manufacture technology of temperature transmitter convenient to assemble

Abstract

The invention provides a manufacture technology of a temperature transmitter convenient to assemble, and solves the technical problems that a present portable temperature transmitter has not corresponding manufacture technology, is assembled only relying on artificial experience and is complex in the manufacture process. The temperature transmitter comprises a casing, a terminal bench, a probe, acable joint, a panel, a detection unit, a single-chip microcomputer, a D / A conversion module, a mainboard, a display screen, an insulated sponge cushion, a backing plate and an elastic clamping element. The manufacture technology comprises the following steps that S1) the casing of the temperature transmitter is prepared; S2) the backing plate is placed on a first conveying system of an assemblingsystem, and a punched backing plate is obtained; and S3) the elastic clamping element is placed on a second conveying system of the assembling system, so that the elastic clamping element is mountedon the backing plate, and an integrated backing plate is obtained. The technology has the advantage of simple manufacture.

Description

technical field [0001] The invention relates to a manufacturing process, in particular to a manufacturing process of an easy-to-assemble temperature transmitter. Background technique [0002] A temperature transmitter is an instrument that converts temperature variables into a transmittable standardized output signal, and is mainly used for the measurement and control of temperature parameters in industrial processes. The temperature transmitter uses thermocouples and thermal resistances as temperature measuring elements, and the output signal from the temperature measuring elements is sent to the transmitter module, after voltage stabilization filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse After protection and other circuit processing, it is converted into a 4-20mA current signal 0-5V / 0-10V voltage signal that is linearly related to the temperature, and the RS485 digital signal is output. [0003] After searching, f...
