Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further：
Referring to Fig. 1 and Fig. 2, the utility model provides electronic product aging testing apparatus, and it includes temperature sensor, band
PLC display, controlling switch, dc source generator, air heater and multiple station control box；Display with PLC
Input connection temperature sensor, output end connection controlling switch, the first control end connection station control box, the second control end
Connect dc source generator；Controlling switch connects air heater, dc source generator and station control box respectively
Power input, the control end of each station control box is connected with the control end of adjacent station control box, station control box
Corresponded with electronic product, and the power outlet of station control box or power output end connect the power input of electronic product
End.Dc source generator connects station control box.
Display with PLC can also be replaced with common PLC combination other display equipment, can also use industry control
Computer is replaced.Dc source generator can be the dc source or uncontrollable dc source adjusted manually.Each
Station control box is provided with the electronic product of station one test to be aging of correspondence, each station.
When there is electronic product to need test, tester first opens the total power switch of test system, now station control
Box processed can first close out-put supply switch, then carry out self-inspection, the display with PLC inquires about each work by data/address bus one by one
The self-detection result of position control box, after the completion of self-inspection, tester lays out electronic product in each station of testing jig one by one, then according to
Power demands according to product access power line the AC Power supply socket or DC power output end of station control sum, then beat
The starting switch gone into operation in a control box.Then, tester according to electronic product aging demand, by aging temperature, product
The data such as power type, supply voltage, running current, ageing time are input manually into the display with PLC, Zhi Houqi
Dynamic burn-in test.
After burn-in test starts, the display with PLC just passes through control according to the data of input if necessary, with alternating current
Switch and provide AC power for each station control box, can just be set if necessary, with direct current by dc source generator
It is fixed, it is each station control box supply direct current.Hereafter the display with PLC is again by the running current and ageing time of product
Each station control box is sent to etc. data, makes each station control box to electricity operation on product.If necessary to high temperature ageing, then use
Temperature in air heater and temperature sensor control room, it is ensured that indoor temperature meets aging requirement.
Air circulation fan is further may also include, air circulation fan connection controlling switch.Needing to carry out high temperature
During burn-in test, by air circulation fan, further strengthen indoor air flows, preferably control indoor air temperature.
The station control box include shell, shell provided with power outlet, DC power output end, starting switch and
Indicator lamp, is provided with a circuit board in shell, and the circuit board is provided with single-chip microcomputer, electrical level transferring chip, Hall current sensor, the
One relay, the second relay, the indicator lamp, Hall current sensor, electrical level transferring chip, the coil of the first relay
End, the coil-end of the second relay are connected with single-chip microcomputer；Outside alternating current passes sequentially through controlling switch, the first relay
Switch terminals connect Hall current sensor, and dc source generator connects Hall current by the switch terminals of the second relay and sensed

485 level signals are converted to the Transistor-Transistor Logic level signal of single-chip microcomputer needs, and address sets switch to be used to set each station control box
Mailing address.
Before burn-in test starts, the single-chip microcomputer in station control box first pass through the first relay, the second relay shut-off it is defeated
Go out the power of alterating and direct current to power outlet and power supply terminal, the output valve of Hall current sensor is then detected, if this value connects
Mid-point voltage as defined near then thinks that Hall current sensor is working properly, and it is the defeated of Hall current sensor to record this value
Go out value for 0 Current Voltage point.Single-chip microcomputer will open corresponding relay and start after each aging data that bus is sent is received
To voltage ageing on electronic product.Hereafter single-chip microcomputer does not stop to read Hall current sensor with the speed per second for being not less than 10k times
Output valve, then actual current value is calculated as by formula, when the average current value in certain time is all beyond the normal model of setting
When enclosing, judge that exception occurs in the electronic product in survey, now single-chip microcomputer will control the first relay and the second relay to cut immediately
Disconnected aging power supply, while abnormal information to be rewinded to PLC display by bus feedback.Setting value is reached when the aging cumulative time
Afterwards, single-chip microcomputer can also close output voltage in time, to save power consumption.
After the aging testing apparatus provided using the utility model, not only there is provided total for the working strength of reduction tester
The utilization rate of body test speed and aging testing apparatus, can more be greatly lowered to burn out and survey product or even damaging burn-in test system
The risk of system.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim
Within the scope of.
