Abstract
The utility model discloses a kind of NTC power type thermal resistance autompulse test machine, comprise travelling belt, travelling belt equidistantly arranges resistance draw-in groove, resistance draw-in groove pros and cons is connected with positive lead, negative lead respectively, described travelling belt is also provided with and positive lead, the equal adaptive power supply of negative lead, power supply, positive lead, negative lead and resistance draw-in groove form series loop.Also be provided with reometer in described series loop, reometer is all connected with controller with power supply.Described travelling belt is connected with stepper motor.Distance between described resistance draw-in groove is identical with the step distance of travelling belt.Described controller is connected with alarm.Adopt design of the present utility model, control power supply by controller and use crest voltage to the voltage examinations determination product of product quality, and by the monitoring of controller, Timeliness coverage defective products, and by alarm equipment alarm, control in real time to produce line yield, be imbued with practicality.
Description
Technical field
The utility model relates to a kind of thermistor test machine, particularly a kind of NTC power type thermal resistance autompulse test machine.
Background technology
Existing thermistor test generally adopts manual operation, but not adopts the Automation Design, and efficiency is low, and automaticity is low.
Utility model content
Utility model object: the purpose of this utility model is to solve the problem that existing power type thermal resistance test machine efficiency is low, automaticity is low.
Technical scheme: the utility model provides following technical scheme: a kind of NTC power type thermal resistance autompulse test machine, comprise travelling belt, travelling belt equidistantly arranges resistance draw-in groove, resistance draw-in groove pros and cons is connected with positive lead, negative lead respectively, described travelling belt is also provided with and positive lead, the equal adaptive power supply of negative lead, power supply, positive lead, negative lead and resistance draw-in groove form series loop, also be provided with reometer in described series loop, reometer is all connected with controller with power supply.
As optimization, described travelling belt is connected with stepper motor.
As optimization, the distance between described resistance draw-in groove is identical with the step distance of travelling belt.
As optimization, described controller is connected with alarm.
Principle of work: stepper motor drives travelling belt uniform motion, each thermistor embedded resistor draw-in groove, travelling belt often advances a segment distance, both positive and negative polarity connecting line is connected with power supply, controller controls power supply and sends pulse current and test thermistor, and the actual current data that records is delivered to controller by reometer, and controller records electric current and normal current makes contrast by actual, if abnormal, then control alarm equipment alarm.
Beneficial effect: the utility model compared with prior art: adopt design of the present utility model, controlling power supply by controller uses crest voltage (generation pulse current) to the voltage examinations determination product quality of product, and by the monitoring of controller, Timeliness coverage defective products, and by alarm equipment alarm, control in real time to produce line yield, the utility model automaticity is high, efficiency is high, is imbued with practicality.
Accompanying drawing explanation
Fig. 1 is plan structure schematic diagram of the present utility model.
