Positive temperature coefficient thermistor resistance value detection device

Abstract

The invention discloses a positive temperature coefficient thermistor resistance value detection device. The positive temperature coefficient thermistor resistance value detection device comprises a base, a sorting cavity with an upward opening is formed in the top end face of the base, a sorting and discharging mechanism used for sorting qualified and defective products is arranged in the sorting cavity, and a working box is fixedly arranged on the top end face of the base. A heating working block is fixedly arranged on the right side end surface of the working box. According to the positive temperature coefficient thermistor resistance value detection device, through electromagnetic conversion, real-time monitoring of the resistance value of a thermistor is achieved, the temperature is compared, the electronic resistance value is visually reflected to the outside world under the temperature change condition, the outside world can rapidly, easily and conveniently observe whether the thermistor can interrupt the expected working effect or not under the working temperature condition, whether the thermistor is qualified or not is rapidly judged, after detection of the thermistor is completed, reverse sorting of the thermistor is automatically completed, the qualified products fall into a qualified product box, the defective products are collected in a defective product box, sorting of the detected thermistor is completed, rapidness and high efficiency are achieved, and the labor cost is saved.

Description

technical field [0001] The invention relates to the related technical field of electronic components, in particular to a positive temperature coefficient thermistor resistance detection device. Background technique [0002] During the production process of the thermistor, it needs to be tested. The current detection method is generally to place the thermistor in a constant temperature oil tank, and then manually hold the detection electrode to complete the detection. This detection method is cumbersome and inefficient. , the labor cost is high, and now a fully automatic detection device has also appeared. This detection device transports the thermistor into the constant temperature oil tank, and then completes the detection by the automatic detection manipulator. The process realizes automatic operation and high efficiency, but The high cost of fully automatic detection devices is unaffordable for some small-scale enterprises, which limits its popularization and application....
