Description
Technical field
The utility model relates to a kind of temperature measuring equipment of electronic component.
Background technology
The temperature performance test of at present a lot of electron devices, to the uniformity coefficient of test environment temperature, the fluctuation degree is had relatively high expectations.The test of some electron device can only be carried out in calibration cell, and general standard thermostatic groove all adopts the simulation temperature control instrument, promptly imports single constant temperature point temperature value with manual adjustments, is incubated reach the constant temperature value of setting when the groove temperature after.But the test request of these devices carries out at different temperature sections, and elevation rate is all had requirement, and too soon, all the part testing performance is impacted too slowly, so solution to this problem is preferably controlled with computer programming input temp curve.But the standard thermostatic groove all adopts the simulation temperature control instrument, is provided with communication interface with computing machine, also just can't with the computing machine communication.And oil groove does not have cooling system again, behind the oily temperature rise value, can only natural cooling can't satisfy the requirement of rate of temperature fall.
Summary of the invention
The purpose of this utility model provides a kind of full-automatic testing device that is used for operating temperature, recovery temperature and the contact resistance of relay.
Utility model is to realize above purpose like this.
Be provided with display, computing machine and digital temperature controller and be connected the full-automatic testing temperature device of temperature control tank on control desk, computing machine is a host computer, and digital temperature controller is a slave computer, and digital temperature controller is connected by the RS-232C communication interface with computing machine; Described temperature control tank is by cryostat,, and oil groove and water tank constitute, and digital temperature controller is connected by lead with cryostat, with oil groove respectively.
In order to realize above purpose better, be provided with condenser pipe and water inlet pipe in the described water tank, be provided with heating tube and cooling water pipe in the oil groove, the rising pipe of its cooling water pipe and water tank joins.
The utility model has the advantages that the employing computer control,, obtain different pid value (differential, integration, ratio value) by adjusting certainly, be arranged in different PIDNO number for different temperature sections, temperature fluctuation, uniformity coefficient can reach ± and 0.02 ℃.
The numeral temperature controller is connected with computing machine by communication interface, by temperature variation in the temperature control curve controlled oil groove of input.
In oil groove, be provided with heating tube and cooling water pipe, make the working temperature of oil groove can reach 5 ℃～150 ℃ scopes.

Among the figure: 1-cooling water tank, 2-water pipe, 3-oil groove, 4-anchor clamps, 5-cryostat,, 6-lead, 7-numeral temperature controller, 8-digital watch, 9-printer, 10-computing machine, 11-display, 12-control desk, the 13-temperature control tank, 14-water inlet pipe, 15-rising pipe, 16-condenser pipe, 17-heating tube, 18-cooling water pipe.
Embodiment
Below be in conjunction with the accompanying drawings to the utility model and implement the detailed description of side.
Control desk 12 of the present utility model is provided with digital temperature controller 7, digital watch 8, printer 9.Computing machine 10 is a host computer, and digital temperature controller 7 is that slave computer also is connected communication by the RS-232C interface with computing machine 10.By Fig. 1, Fig. 2 as can be seen this device also be provided with temperature control tank 13, the digital temperature controller 7 that water tank 1, oil groove 3 and cryostat, 5 constitute and be connected by lead 6 with cryostat, 5 with oil groove 3 respectively.Also be provided with condenser pipe 16 and inlet tube and outlet tube 14,15 in the water tank 1, be raised to fast cooling behind the certain value, in oil groove 3, be provided with heating tube 17 and cooling water pipe 18 for making temperature control tank 13.Its cooling water pipe 18 joins with the rising pipe 15 of water tank 1.To satisfy oil groove 3 working temperatures is the requirement of 5～150 ℃ of scopes, during oil groove 3 temperature≤40 ℃, the employing initial temperature is 0 ℃ refrigerating machine circulation cooling, so just can guarantee that minimum temperature is+5 ℃ requirement, and when oil groove 3 temperature＞40 ℃, employing tap water cooling, the water vapour that produces during oil groove 3 temperature 〉=100 ℃ discharges and safety problem can not take place to the pond like this.
After operating personnel programme groove temperature control curve negotiating, input computing machine 10, computing machine 10 is by the RS-232C interface, with temperature control curve input digit temperature controller.In temperature-rise period, digital temperature controller 7 is pressed the interior actuating medium (oil) of heating tube 17 heating tanks of heating curve (initial temperature, final temperature, heating-up time) control temperature control tank 13, makes the groove temperature rise.In temperature-fall period, as what use is the cryostat, 5 of medium as alcohol, and then computing machine sends the refrigerating machine open command in the cryostat,, makes by condenser pipe that medium temperature descends in the groove.As what use is oil groove 3, and then computing machine 10 sends cooling water valve OPEN and cooling water cycle water pump open command.The cooling water pipe 18 of cooling water flow in oil groove 3 in the water tank 1 descends the medium temperature in the oil groove.In temperature-fall period, digital temperature controller 7 compensates by the heating current of temperature curve while control heater, makes cooling unlikely too fast, to satisfy the requirement of rate of temperature fall.
