The concrete meaning of term in the present invention.
With reference to the accompanying drawing, detailed description of the preferred embodiments.
First embodiment
Fig. 1 is the schematic process flow diagram of the screening technique for the thermistor that the first embodiment of the present invention provides, and is please referred to
Fig. 1, the screening technique of the thermistor the following steps are included:
Step S101, by frock clamp clamping standard thermistor, so that standard thermistor is in frock clamp shape
At detection space in.
In this step, standard thermistor is the resistance value essence chosen according to the manufacturing parameter of batch thermistor to be measured
Spend higher thermistor.
Wherein, frock clamp is the cylindrical shape of top sealing, and detection space is surrounded by its peripheral wall with roof jointly, tooling folder
Clamping part is provided on the roof of tool, clamping part has good electric conductivity, and the peripheral wall and roof of frock clamp insulate, and clamps
Portion is used for clamping standard thermistor, and clamping part has connector lug through roof indwelling, for being electrically connected with resistance monitor, tooling
The peripheral wall of fixture and the detection space temperature caused by outside air flowing that reduces of roof high degree change, and maintain inspection
Spatial stability is surveyed, that is, ensure that the ambient stable of standard thermistor.
Further, the screening technique of the thermistor further include:
General resistance braid machine is placed in an isoperibol, and is preheated by step S102, so that the temperature of screening unit
Reach operating temperature.
In this step, the steady temperature of isoperibol is 25 ± 0.1 DEG C, and in the present embodiment, this isoperibol one is empty
Between transferring house, by adjusting air-conditioning, so that the temperature in room is maintained at 25 ± 0.1 DEG C.
In this step, screening unit is for screening the position of thermistor on general resistance braid machine, in practical screening
In the process, screening unit can generate heat, and temperature increases, to influence the accuracy of thermistor screening.
Further, the screening technique of the thermistor further include:
Step S103 will test space and be connected to the screening unit that general resistance braid machine is used to screen thermistor to be measured,
And detection space is heated by screening unit, so that the detection temperature in detection space and the operating temperature of screening unit are consistent.
Because screening unit can generate heat in practical screening process, temperature is increased, to influence the standard of thermistor screening
True property, therefore, in this step of the screening technique of thermistor provided by the invention, detection that standard thermistor is in
Space is connected to screening unit, and screening unit heats detection space, so that environment temperature locating for standard thermistor is examined
Testing temperature is identical as the operating temperature of screening unit, so as to detect in the subsequent resistance value to standard thermistor, obtains general electricity
During the reference resistance value for hindering braider, the reference resistance value measured is more accurate, so that the selection result is relatively reliable.
Further, the screening technique of the thermistor further include:
Standard thermistor is electrically connected by step S104 with resistance monitor.
Step S105, standard thermistor of the detection at a temperature of detection, obtains with reference to resistance value.
Step S104 and step S105 is to obtain the process for detecting and obtaining with reference to resistance value.In step S104, by clamping part
Connector lug is electrically connected with resistance monitor, this resistance monitor is the instrument of common detection resistance resistance value；In step S105, temperature-sensitive
Resistance is at a temperature of detection, and detection temperature is equal to the operating temperature of screening unit, and frock clamp high degree reduces the external world
Detection space temperature variation caused by air flowing maintains detection space after screening unit is to detection space heating
Temperature is stablized, that is, ensure that the ambient temperature-stable of standard thermistor, therefore, the mark at a temperature of resistance monitor detection detection
The reference temperature that quasi- thermistor obtains has stronger convincingness.
Further, the screening technique of the thermistor further include:
Thermistor to be measured is placed in screening unit and stands 3 minutes by step S106.
In this step, by thermistor to be measured be placed in screening unit stand 3 minutes, screening testing resistance between, be for
So that testing resistance is sufficiently adapted to operating temperature, screens it at steady-state, improve testing resistance and screened
The accuracy of journey reduces error.
Further, the screening technique of the thermistor further include:
Step S107 screens range according to the resistance value of reference resistance value setting general-purpose resistance braid machine, and screens according to resistance value
Range is treated survey thermistor and is screened.
General resistance braid machine has the function of automatic batch detection resistance resistance value, and it is general that thermistor to be measured is inputted this
After resistance braid machine, range is screened according to the resistance value of setting and is screened.
When screening batch thermistor with precision, based on resistance value is referred to, successively ascending setting resistance value screens model
It encloses, resistance value screening range setting is smaller, and the precision of obtained thermistor is higher.For example, if being 5K Ω with reference to resistance value, by small
To big setting Standard resistance range, the A range of setting 5 ± 0.1K Ω first is screened to obtain part a thermistor, reset 5 ±
The B range of 0.2K Ω is screened to obtain part b thermistor, then, the resistance accuracy of a thermistor is higher than b thermistor
Resistance accuracy, and so on, ascending setting screening range is screened, and the precision sieve to batch thermistor can be completed
Choosing.
When screening purpose is to distinguish NTC thermistor and PTC thermistor:
NTC thermistor increases resistance value with temperature and reduces, according to the resistance value model reduced with reference to resistance value setting based on its numerical value
It encloses, that is, setting is less than the numerical value with reference to resistance value to the range referred between resistance value by one, can screen to obtain NTC thermistor；
PTC thermistor increases resistance value with temperature and increases, according to the resistance value model increased with reference to resistance value setting based on its numerical value
It encloses, that is, setting is greater than the range between the numerical value with reference to resistance value by reference resistance value to one, can screen to obtain PTC thermistor.
The screening technique of thermistor provided by the invention accurately efficiently obtains the reference resistance value that batch screens foundation,
Cumbersome process in the prior art is saved, can be improved the screening efficiency of thermistor, quickly screens large batch of temperature-sensitive electricity
Resistance.
