The AD signal for entering main control module after flowing and amplifying inputs, and carries out the identification of amplitude height, another part to signal by AD
Function is that the capture input port of main control module is input to after signal is compared shaping, carries out the identification of frequency signal, and final
Whether amplitude signal and frequency signal are judged in the normal range, whether the performance to determine microphone is normal；It is described
Main control module by magnet control module 23 control connection electromagnet 14, the Hall sensor to mobile phone subplate 10 to be measured into
When row detection, main control module passes through magnet control module 23 first and issues level signal, which can make electromagnet
On 14 faces mobile phone subplate 10 to be measured Hall sensor that one end generate the pole N, Hall sensor sense N pole field it
Afterwards, a low level signal can be generated, which produces by board to board connector 16, using the second switching winding displacement 19, letter
Number input module 25 sends main control module back to, after main control module detects the low level signal, judges that N pole field tests OK, otherwise
Judge N pole field test crash.Then, main control module issues level signal, the level again by magnet control module 23
Signal can make that one end of Hall sensor on 14 face of electromagnet mobile phone subplate 10 to be measured generate the pole S, and main control module is again
Judge whether the signal measured is low level.Only the signal of the pole N and the pole S is all OK, and the test of Hall sensor is only OK,
Otherwise test crash；For the main control module by showing that output module 28 is connected to liquid crystal display 9, testing result passes through display

A part, one is the AD signal input that signal is carried out to precision rectifying and enters main control module after amplifying, by AD to signal
Carry out amplitude height identification, another part function be input to after signal is compared shaping main control module capture it is defeated
Whether entrance carries out the identification of frequency signal, and finally judge in the normal range amplitude signal and frequency signal, with
Determine whether the performance of microphone is normal.After microphone interface checks, to the Hall sensor of mobile phone subplate 10 to be measured into
Row detection, main control module pass through magnet control module 23 first and issue level signal, which can make electromagnet 14
That one end of Hall sensor generates the pole N on face mobile phone subplate 10 to be measured, after Hall sensor senses N pole field,
A low level signal can be generated, which produces by board to board connector 16, defeated using the second switching winding displacement 19, signal
Enter module 25 and send main control module back to, after main control module detects the low level signal, judges that N pole field tests OK, otherwise judge N
Pole field test crash.Then, main control module issues level signal, the level signal energy again by magnet control module 23
That one end of Hall sensor on 14 face of electromagnet mobile phone subplate 10 to be measured is enough set to generate the pole S, main control module judges to survey again
To signal whether be low level.Only the signal of the pole N and the pole S is all OK, and the test of Hall sensor is only OK, otherwise surveys
Examination failure.After the completion of all of above detection, main control module will test result by showing that output module 28 is sent to liquid crystal display
Screen 9, and shown by liquid crystal display 9, above three testing results of display.If detecting successfully, test result refers to
Show that lamp 8 shows green, if detection failure, test result indicator light 8 are displayed in red, and alarmed by buzzer 29,
To remind worker to detect failure.Finally, TYPE C male connector 17 is extracted, the handle 1 of pushing is lifted, the mobile phone being successfully tested
Subplate takes out, and is put into corresponding antistatic case, in case subsequent process uses, by the mobile phone subplate of test crash, according to liquid
The failure information prompted on crystal display screen is repaired accordingly.It is put into new mobile phone subplate to be measured, carries out test next time.
The mobile phone subplate device for quick testing does not need the participation of worker in entire test process, and worker only needs
Taking and putting measured mobile phone subplate is wanted, a people can operate more machines simultaneously, greatly improve the production efficiency of worker, together
Shi Ruguo picks and places plank plus manipulator in the later period, and computer is connected by way of serial communication with this equipment, and issues and open
The order of beginning test, so that it may realize automatic test.The mobile phone subplate device for quick testing, audio collection module pass through
The voltage value of voice signal and frequency values are acquired out by the mode of full-wave rectification and comparator, the property of comprehensive descision microphone
Can, greatly improve the reliability of test result.The mobile phone subplate device for quick testing passes through liquid crystal display, state instruction
Lamp and buzzer remind worker to integrate, and provide convenience to the maintenance of bad products, while also saving what maintenance was spent
Cost of labor.
