Problems solved by technology
[0002] At present, the temperature detection of the thermal fuse is mainly carried out by the detection personnel in real time to monitor the temperature of the detection environment (oven) when it is in motion. The detection efficiency is low and the subjective factors have a great influence on the detection accuracy.
Moreover, during the inspection, only unqualified products can be roughly detected, and the unqualified parameters of the thermal fuse cannot be detected with high precision, which is not conducive to the reverse speculation and search for the cause of the problem in the production process of the thermal fuse.

The invention provides a thermal link operating temperature intelligent detector, which can improve the detection accuracy rate, detection precision and detection efficiency, can reduce the labor intensity of the staff, can provide high-precision parameters of defective products, and is conductive to reverse speculation and search of causes of problems in the process of thermal link production. The thermal link operating temperature intelligent detector comprises an oven equipped with a heater. The oven is internally provided with a plurality of thermal link sample detection stations. Each thermal link sample detection station is connected in series in an independent detection circuit. Each detection circuit comprises a constant current source connected in series with the corresponding thermal link sample detection station. Each thermal link sample detection station is further provided with an independent thermocouple. Each constant current source and the corresponding thermocouple are connected with an intelligent control module. The heater is connected with the intelligent control module.
Description
technical field [0001] The invention relates to the technical field of electrical component testing instruments, in particular to an intelligent detector for the action temperature of a thermal fuse. Background technique [0002] At present, the detection of thermal fuse action temperature is mainly carried out by inspectors in real time to monitor the temperature of the detection environment (oven) when it operates. The detection efficiency is low and subjective factors have a great influence on the detection accuracy. Moreover, during detection, only unqualified products can be roughly detected, and the unqualified parameters of the thermal fuse cannot be detected with high precision, which is not conducive to the reverse speculation and search for the cause of the problem in the production process of the thermal fuse. Contents of the invention [0003] The purpose of the present invention is to propose a thermal fuse action temperature intelligent detector, which can im...
