The micro motor endurance testing device
Technical field
The utility model relates to the device that is suitable for a kind of micro motor life test.
Background technology
The micro motor test, tradition is with regard to the test of switching on what carrier with where.With the mobile phone is example:, all be welded on the position of mobile phone correspondence the laggard electrical testing that works of device finished product mobile phone for the motor for cell phone vibration-testing with motor.Shortcoming is dismantled, installs cumbersome, and easily bar structure spare is made a mess of; Simultaneously, test for the mobile phone products correspondence that the motor of different size need be different, every mobile phone can only be tested a motor, for the motor that requires to test the quantity life test, has improved experimentation cost undoubtedly; And the client is for the life test condition, especially shakes, to go up regulation between the stopping time different, if realize that this different the requirement must the change softwares, the program of reburning has increased workload, and the test period is elongated.If carrier-free is only tested then the supplied materials motor and can't be finished test.
Summary of the invention
The purpose of this utility model is to solve dismounting in the existing test, trouble is installed, and structural member is fragile, test limited amount system, and can't change defective such as test condition fast, guarantee that the reliability of micro motor test in the product is protected.
The purpose of this utility model is achieved through the following technical solutions:
A kind of micro motor endurance testing device comprises a time relay, and a plurality of test platforms link to each other with this time relay, are provided with connection welding on each test platform.
Wherein, the quality of this test platform is identical in quality with the mobile phone that adopts the motor that needs test.
This device also comprises a counter, and it links to each other with this time relay.
And this device is provided with a D.C. regulated power supply, and it links to each other with this time relay.
Positive progressive effect of the present utility model is: micro motor life test that can the multiple different model specification of adaptive testing, and quantity can be regulated according to the D.C. regulated power supply output power, and easy and simple to handle; Because the utilization of the time relay has solved any adjusting of switching time, satisfy various test requests simultaneously.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model one embodiment.
Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1, a kind of micro motor endurance testing device is provided with a D.C. regulated power supply 1, and it can adopt any one that sell on the market can regulate the D.C. regulated power supply of output voltage.
A time relay 2 links to each other with this D.C. regulated power supply 1, and the time relay 2 regularly opens or closes circuit, promptly makes power on circuitry, disconnecting circuit then at regular intervals.Interlude is adjustable.This time relay 2 can use the adjustable time relay of any one time at present.
A plurality of test platforms 3 link to each other with this time relay, which is provided with connection welding 31.The concrete number of test platform 3 can be set according to actual needs
Wherein, the quality of this test platform 3 is identical in quality with the mobile phone that adopts the motor that needs test.Mobile phone quality commonly used at present is that 90 grams are to 100 grams.By the quality of control test platform, the state the when state when making test uses on mobile phone with motor is identical or close, thereby obtains test data more accurately.
This device also comprises a counter 4, and it links to each other with this time relay 2, is used for effectively writing down the life test time.When pulse of time relay 2 every outputs, then counting increases by one, and the life-span of motor just multiplies each other according to the time of the value of counter 4 and the time relay 2 and obtains.
