Embodiment
The technical solution of the utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, the automatic test philosophy frame diagram of a kind of relay that the utility model is related to, including computer,
Comprehensive parameter tester of relay, separator, electrostatic ion eliminator, measured relay, ink jet numbering machine, smoke purifier.Relay
Device is slided at test position under stepper motor and self gravitation double action through guide rail, the sensor that guide rail front end is provided with
A signal is exported after sensing and informs and can be tested that after having tested, computer is according to test result with setting to computer
Determine after voltage division rank is compared, to inform which rank ink jet numbering machine sprays, be finally automatically put into specified expects pipe rewinding；Described
Electrostatic ion eliminator is used for dust on daily cleaning guide rail and test bench, it is ensured that product glides smooth and test reliably；It is described
Ink jet numbering machine be used for voltage be classified coding, smoke purifier be used for eliminate coding generation smell.
To ensure that following Comparability test can be smoothed out, sorting main machine base palpus leveling, and reliable ground, it is anticreep；For
Source of the gas oil-free compressed air is given, air pressure is controlled in 0.4-0.6MPa.
The detection structure chart of the relay test system is as shown in Figure 2.Take 10 rated voltage 48V relay contact analog control system samples
Product do pick-up voltage test Comparability test on iron material matter guide rail, non-ferric material guide rail, test bench respectively, and are compiled according to 1-10
Number.
As shown in figure 4, manual test seat test mode step common in the art is as follows：First ensure that computer,
Tester associate device is powered, and communication connection is intact, and test must use four line methods of testing to ensure test accuracy, according to test
Instrument specification requirement, on the correspondingly connected reed into test fixture of supply lines and detection line, will be sure not hybrid junction cause it is short
Road can not be tested, and be fixed with heat-shrinkable T bush, it is ensured that after p-wire connection is errorless, relay pin is properly inserted into reed
In 7, it is ensured that contact is reliable, 10 48V relays are tested successively, test data is kept.
As the contrast test of the utility model specific embodiment, the detection examination in the case where guide rail is ferrous material has also been carried out
Test.Step includes：Ensure that the associate devices such as computer, tester, separator are powered and communicate to connect intact, the same hand of the mode of connection
Work test bench is connected, it is ensured that p-wire connection is errorless, tests 10 48V relays successively on iron material matter guide rail, keeps survey
Try data.
As the utility model specific embodiment, using detecting system disclosed in the utility model, led in non-ferric material
Detection experiment is carried out in the case of rail, step includes：Ensure that the associate devices such as computer, tester, separator are powered to communicate
Connection is intact, and the mode of connection is connected with manual test seat, it is ensured that p-wire connection is errorless, is tested successively on non-ferric material guide rail
10 48V relays, keep test data.
The data preparation for testing to obtain under above-mentioned three kinds of modes is good, it see the table below：
As seen from the table, offset using the separator busy relay pick-up voltage of iron material matter guide rail with manual test bright
It is aobvious, and use the separator test result of non-ferric material guide rail to be consistent with manual test.
As shown in figure 3, during relay power test, iron core 4 produces electromagnetic force in coil 6, moving armature 1 is inhaled, drive is pushed away
Dynamic card 3, promotes the upper contact 5 of shell fragment 2 to close, if period is iron material matter guide rail against relay iron, coil side, will produce
Magnetic field is disturbed, when interference magnetic field B2 action direction is identical in the magnetic field B1 directions that coil is produced with iron core, shell fragment adhesive is promoted
Required power is just smaller than original, therefore the pick-up voltage measured is less than normal, when interference magnetic field B3 action direction and iron core are online
Enclose the magnetic direction produced opposite, then the power needed for promoting shell fragment adhesive is just bigger than original, therefore the pick-up voltage measured
Bigger than normal, in a word, the magnetic interference relay contact analog control system that iron material matter guide rail is produced causes pick-up voltage to change.If against after
Electrical equipment iron core, coil side are non-ferric material guide rail, would not produce interference magnetic field, not interfere with relay contact analog control system, then
The pick-up voltage measured is exactly real value, it is ensured that the accuracy of test result.
By analysing in depth, if relay1 case is made up of metal material, to meet normal usage function, built-in iron
Core, armature, coil structure portions must be passed through specially treated, not disturbed and the normal work of energy by external magnetic field during ensureing to be powered
Make.
Only preferred example of the present utility model is described above, but is not to be construed as limiting the scope of the invention.
The utility model is not limited only to above example, and its concrete structure allows to change.In every case in the utility model independent claims
Protection domain in the various change made in protection domain of the present utility model.
