Production equipment for integrated film temperature sensor

Abstract

The invention discloses production equipment for an integrated film temperature sensor. The production equipment includes a first guide wheel, a guide groove, a mold for thrusting wires, a mechanicalarm for pulling wires, second guide wheels respectively disposed on the upper and lower sides of the first guide wheel and used for guiding films, hot pressing rollers disposed downstream of the mechanical arm (or the guide wheels), and a slitting machine disposed downstream of the hot pressing rollers. The inner sides of an upper film and a lower film are coated with glue. A plurality of NTC resistors are welded between two parallel wires at intervals to form a wire group. A plurality of wire groups enter the front end of the guide groove in parallel and at intervals via the first guide wheel. The mold thrusts the wires. The mechanical arm (or the guide wheels) pulls the broken wires along the guide groove to between the two films coated with glue. The broken wires are clamped between thetwo films coated with glue and enter the hot pressing rollers for hot pressing. The slitting machine slits the films after hot pressing. The production equipment has the advantages as follows: the equipment has a high degree of automation and needs fewer operators; and the equipment is conducive to mass production.

Description

Technical field [0001] The invention relates to a production equipment of an integrated thin film temperature sensor. Background technique [0002] Thermistor temperature sensor is a kind of temperature sensor that uses the principle that the resistance value of a conductor or semiconductor changes with temperature to measure temperature. It includes a thin film thermistor and an NTC temperature sensor. The current thin film thermistor mainly encapsulates the bare chip thermistor in a thin film through a metal bracket, and then solders the pins of the metal bracket and the thermistor through soldering. The melting temperature of the solder is about 180°C. When the temperature exceeds 180°C, the connection between the thermistor's pin and the bracket will be detached due to the dissolution of the solder, resulting in the temperature cannot be measured, and the length of this thin-film thermistor is generally only 50mm at the longest, and a wire needs to be passed For connection, ...
