Please refer to Fig. 1, this Figure 1 shows that the main flow chart of an embodiment of mobile phone test frock detection method of the present invention.In this embodiment, test fixture is in order to test mobile phone PCBA, be provided with dismountable test fixture thereon, include power supply test module, communication port test module, key testing module, receiver test module, loud speaker test module, vibration-testing module, Mike's test module and display screen test module on the anchor clamps.
As shown in Figure 1, this embodiment is as follows to the detailed process that test fixture detects:
Step 101: place the mobile phone PCBA that is up to the standards at test fixture, and be electrically connected with each test module in the anchor clamps.
Place a qualified mobile phone PCBA at test fixture anchor clamps to be detected, each test module in the anchor clamps contacts with the leakage copper point of mobile phone PCBA test point by thimble and realizes being electrically connected, or realize being electrically connected by connecting line connection PCB A buckle, consist of the complete test macro of testing mobile phone PCBA.
Step 102: test fixture is connected with PC, utilizes the power supply test module in the test fixture to be mobile phone PCBA power supply.
When detecting test fixture or testing mobile phone PCBA, all need test fixture is connected with PC, realize corresponding detection by means of PC.
Step 103: the communication port of scanning PC.
Mobile phone PCBA utilizes the power supply test module power supply in the test fixture, and communicates by communication port test module and the PC in the test fixture.And follow-up test process must guarantee that mobile phone can work on power, also can carry out proper communication with PC, so that PC send out control command can for mobile phone PCBA.Therefore, whether normal this embodiment at first tests its power supply test module and communication port test module when test fixture.Concrete operations are: after for mobile phone PCBA power supply, the communication port of scanning PC, if scan the mobile phone port, illustrate that mobile phone PCBA normally powers on and can establish a communications link with PC, show namely that also power supply test module and the communication port test module in the test fixture is normal.If scanning less than the mobile phone port, may be that the power supply test module so that mobile phone PCBA can't work on power, also may be communicate by letter because the communication port test module causes mobile phone PCBA to set up with PC unusually unusually.
Step 104: judge whether to scan the mobile phone port.If go to step 106; If not, execution in step 105.
The mobile phone port has specific port numbers, whether has the mobile phone terminal slogan by judging PC and communication port, can judge whether to scan the mobile phone port.
Step 105: if do not scan the mobile phone port, prompting communication port test module or power supply test module are unusual.
The technical staff can check components and parts, thimble and the connecting line of these two test modules targetedly according to this abnormal prompt, is convenient to find fast fault and eliminating.
Step 106: if scan the mobile phone port, judge that communication port test module and power supply test module are normal.After this, can utilize PC and mobile phone PCBA to detect other test modules.
In this embodiment, for guaranteeing that detecting used mobile phone PCBA is that detection is qualified, consider qualified PCBA(gold plate) specific identification information is arranged, before carrying out other test modules detections, judge first whether the mobile phone PCBA that places on the test fixture is qualified product.Concrete decision process such as following step 107 as described in 110.
Step 107: after judging that communication port test module and power supply test module are normal, read mobile phone PCBA identification information by the communication port test module.
Mobile phone PCBA normally work on power and test job in the communication port test module normal after, PC sends control command, read mobile phone PCBA identification information, such as software version number and the production sequence number of mobile phone, this instruction transfers on the mobile phone PCBA through the communication port test module.Mobile phone PCBA receives this instruction, and the identification informations such as its software version number and production sequence number are fed back on the PC by the communication port test module.
Step 108:PC is machine-readable get the identification information of current phone PCBA after, compare with default identification information, judge whether to be complementary with default identification information.If coupling goes to step 110; Otherwise, execution in step 109.
Each piece detects the identification information that qualified PCBA all has this PCBA of unique identification, and for example, this identification information is software version number and hardware formation sequence number, and the identification information of these qualified PCBA is pre-stored in PC.After PC reads the identification information of a PCBA, will from the qualified PCBA identification information of having stored, search whether there is current identification information.If find, judge with default identification information to be complementary, if do not find identical identification information, then judge with default identification information not to be complementary.
Step 109: if the identification information of current PC BA and default identification information are not complementary, PCBA is unusual in prompting.
If PCBA is unusual, the technical staff can check whether PCBA is a plate that is up to the standards, so that change real qualified PCBA.
Step 110: if the identification information of current PC BA and default identification information are complementary, utilize PC and test fixture that PCBA is carried out functional test, whether normal with other test modules corresponding to functional test on the detection test fixture.
The concrete testing process of other test modules can be referring to figs. 2 to reaching following description to each figure shown in each figure of Fig. 6.
By above-mentioned testing process, can detect fast, intuitively, exactly power supply test module in the test fixture and communication port test module whether intact and be in place, and on the basis of its detection, again other test modules are detected, improved speed and reliability that test fixture detects.
Shown in Figure 2 is the flow chart that detects the key testing module.Whether normal detailed process is as follows to detect the key testing module:
Step 201: the data collecting card output key useful signal in the control test fixture is to the key testing module.
PC sends control command, and the effective high level signal of data collecting card output key in the control test fixture or low level signal are to the key testing module.The key testing module is carried out corresponding actuation of keys according to the button useful signal, and this actuation of keys can be reflected on the mobile phone PCBA.
Step 202: the feedback information that reads mobile phone PCBA.
The actuation of keys of key testing module will be reflected on the mobile phone PCBA, and PC can obtain by the communication port test module on the test fixture feedback information of mobile phone PCBA, and this feedback information is consistent with actuation of keys.For example, the button useful signal of data collecting card output is to press " menu " key; The key testing module is after receiving this signal, and its " menu " button will be pressed; Mobile phone PCBA will carry out " menu " button, call corresponding module and show " menu ".So the feedback information of mobile phone is exactly the menu that shows mobile phone.
Step 203: judge whether feedback information is consistent with the signal of data collecting card output.If consistent, execution in step 204; Otherwise, execution in step 205.
Step 204: if feedback information is consistent with the signal of data collecting card output, judge that the key testing module is normal.
Step 205: if the signal of feedback information and data collecting card output is inconsistent, for example, mobile phone PCBA does not have feedback information, and feedback information is perhaps arranged, but inconsistent with the signal of data collecting card output, judges that then the key testing module is unusual.
For receiver test module and loud speaker test module, can adopt similar process to detect, specifically shown in Fig. 3 receiver/loud speaker test module testing process.
Step 301: control mobile phone PCBA sends the audio signal of assigned frequency.
PC sends control command, transfers to mobile phone PCBA by the communication port test module in the test fixture, controls the audio signal that it sends assigned frequency.
Step 302: the data collecting card in the control test fixture gathers the output signal of receiver/loud speaker test module.
PC sends control command, gathers the output signal of receiver/loud speaker test module in the control data collecting card, and signal is uploaded in the PC.
Whether PC can be presented at the signal waveform that gathers on the PC interface, and the audio signal waveform that also PCBA can be sent simultaneously shows, by the comparison of two oscillograms, can very clear two signals identical.
Step 303: whether the output signal of judging test module is consistent with the frequency of the audio signal that PCBA sends, and the output signal amplitude of test module is in setting range.If, execution in step 304; Otherwise, execution in step 305.
Step 304: if the audio signal frequency that output signal and the PCBA of receiver/loud speaker test module send is consistent and the output signal amplitude of test module in setting range, judge that receiver/loud speaker test module is normal.
Mobile phone PCBA sends after the audio signal, and this signal will be exported by receiver or loud speaker, and always there is necessarily decay in signal through after receiver or the transmission of loud speaker test module.Therefore, by gathering the output signal of receiver test module or loud speaker test module, the signal that this signal and PCBA are sent compares, if both frequencies are consistent and the amplitude of test module output signal in setting range, send half of signal amplitude greater than PCBA and send the amplitude of signal less than PCBA such as amplitude, illustrate that the audio signal that PCBA sends normally exports by receiver test module or loud speaker test module, and then show that receiver test module or loud speaker test module are normal.
Step 305: if the output signal of receiver/loud speaker test module and audio signal frequency that PCBA sends are inconsistent or the output signal amplitude of test module not in setting range, judge that receiver/loud speaker test module is unusual.
If frequency is inconsistent, perhaps test module output signal amplitude is not in setting range, as send half of signal amplitude less than PCBA, perhaps send the amplitude of signal greater than PCBA, illustrate that then receiver test module or loud speaker test module go wrong, such as components and parts itself fault is arranged, perhaps thimble, connecting line are not in place etc., judge that all receiver/loud speaker test module is unusual.
Whether PC can be presented at the waveform of the output signal of the receiver that gathers/loud speaker test module on the PC interface, and the signal waveform that also PCBA can be sent simultaneously shows, by the comparison of two oscillograms, can very clear two signals identical.
Shown in Figure 4 is the flow chart that detects the vibration-testing module.Whether normal detailed process is as follows to detect the vibration-testing module:
Step 401: control mobile phone PCBA sends the vibration signal of assigned frequency.
PC sends control command, transfers to mobile phone PCBA by the communication port test module in the test fixture, controls the vibration signal that it sends assigned frequency.
Step 402: the data collecting card in the control test fixture gathers the output signal of vibration-testing module.
PC sends control command, gathers the output signal of vibration-testing module in the control data collecting card, and signal is uploaded in the PC.
Whether PC can be presented at the signal waveform that gathers on the PC interface, and the vibration signal waveforms that also PCBA can be sent simultaneously shows, by the comparison of two oscillograms, can very clear two signals identical.
Step 403: whether the output signal of judging test module is consistent with the frequency of the vibration signal that PCBA sends, and the output signal amplitude of test module is in setting range.If, execution in step 404; Otherwise, execution in step 405.
Step 404: if the vibration signal frequency that the output signal of vibration-testing module and PCBA send is consistent and the output signal amplitude of test module in setting range, judge that the vibrator test module is normal.
Mobile phone PCBA sends after the vibration signal, and this signal will be exported by the vibration-testing module, and always there is necessarily decay in signal through after the transmission of vibration-testing module.Therefore, by gathering the output signal of vibration-testing module, the signal that this signal and PCBA are sent compares, if both frequencies are consistent and the amplitude of test module output signal in setting range, send half of signal amplitude greater than PCBA and send the amplitude of signal less than PCBA such as amplitude, illustrate that the vibration signal that PCBA sends normally exports by the vibration-testing module, and then show that the vibration-testing module is normal.
Step 405: if the vibration signal frequency that the output signal of vibration-testing module and PCBA send is inconsistent or the output signal amplitude of test module not in setting range, judge that the vibration-testing module is unusual.
If frequency is inconsistent, perhaps test module output signal amplitude is not in setting range, as send half of signal amplitude less than PCBA, perhaps send the amplitude of signal greater than PCBA, illustrate that then the vibration-testing module goes wrong, such as components and parts itself fault is arranged, perhaps thimble, connecting line are not in place etc., judge that all the vibration-testing module is unusual.
Shown in Figure 5 is the flow chart that detects Mike's test module.Whether normal detailed process is as follows to detect Mike's test module:
Step 501: the control data collecting card passes through Mike's test module output audio signal to mobile phone PCBA.
PC sends control command, and the data collecting card in the control test fixture is exported the audio signal of assigned frequency and transferred to mobile phone PCBA through Mike's test module.
Step 502: control mobile phone PCBA switches to Mike's loopback status.
PC sends control command, and control mobile phone PCBA switches to Mike's loopback status, also namely controls the output of receiver test module enters mobile phone through Mike's test module signal.
Step 503: the control data collecting card gathers the output signal of receiver test module, and is uploaded to PC.
Whether PC can be presented at the waveform of the signal that gathers on the PC interface, also the audio signal waveform through Mike's output can be shown simultaneously, by the comparison of two oscillograms, can very clear two signals identical.
Step 504: whether the output signal of judging the receiver test module is consistent with the frequency of the audio signal of Mike's test module output, and the output signal amplitude of receiver test module is in setting range.If, execution in step 505; Otherwise, execution in step 506.
Step 505: when the receiver test module is normal, (can adopt the flow process of Fig. 3 to judge whether the receiver test module is normal), if the audio signal frequency of the output signal of receiver test module and Mike's test module output is consistent and the output signal amplitude of receiver test module in setting range, judgement Mike test module is normal.
When mobile phone PCBA is in loopback status, will export by the receiver test module through Mike's test module to the audio signal of mobile phone PCBA, and always there is necessarily decay in signal through after the transmission of receiver test module.Therefore.When the receiver test module is normal, by gathering the output signal of receiver test module, the signal that this signal and Mike's test module are sent compares, if both frequencies are consistent and the amplitude of receiver test module output signal in setting range, send half of signal amplitude greater than Mike's test module and send the amplitude of signal less than Mike's test module such as amplitude, illustrate that the output signal of receiver test module and the output signal of Mike's test module are consistent.Because the receiver test module is normal, and then can judge that Mike's test module is normal.
Step 506: when the receiver test module is normal, if the audio signal frequency that the output signal of receiver test module and Mike's test module send is inconsistent or the output signal amplitude of receiver test module not in setting range, judge that Mike's test module is unusual.
If frequency is inconsistent, perhaps receiver test module output signal amplitude is not in setting range, as send half of signal amplitude less than Mike's test module, perhaps send the amplitude of signal greater than Mike's test module, illustrate that the output signal of the output signal of receiver test module and Mike's test module is inconsistent.And because the receiver test module is normal, illustrate that then Mike's test module goes wrong, and such as components and parts itself fault is arranged, perhaps thimble, connecting line are not in place etc., judge that all Mike's test module is unusual.
The flow process that display screen test module in the test fixture is detected can be with reference to shown in the flow chart of figure 6, and is specific as follows:
Step 601: control mobile phone PCBA shows the appointment screen.
