The present teachings generally relate to novel systems and methods relating to automated functional testing of devices (e.g., hand-held devices like smart phones). More particularly, the present teachings relate to novel systems and methods that automatically test devices for various functionalities, such as their download functionalities, touch screen panel functionalities, camera functionalities and audio functionalities.
Hand-held devices, such as smart phones, have become valuable for more than just making and receiving phone calls. Myriad of features offered by hand-held devices require integration of many complicated components. In the event of device failure, these components are subjected to various tests, most of which are manual in nature. To the extent certain types of tests are automated, they are not automated enough and are, therefore, time consuming and translate into a lower throughput for the device testing process.
What is, therefore, needed are automated systems and methods that automatically, rapidly and accurately test the different functionalities offered by a hand-held device.
To achieve the foregoing, the present arrangements and teachings offer systems and methods relating to automated functional testing of hand-held devices. In their failed state, hand-held devices are subjected to testing, according to present systems and methods, and are referred to as “test devices.” Once the test devices are tested for defects, their identified defects are repaired, and they are reconfigured to their original factory form. In their reconfigured form, the hand-held devices may be sold as a refurbished item.
In one aspect, the present teachings provide automatic functional testing systems. One exemplar automatic functional testing system includes: (i) a touch screen panel (“TSP”) load conveyor; (ii) a TSP unload conveyor; (iii) a TSP reject conveyor; (iv) multiple TSP testing jigs; (v) multiple TSP testing shuttles; (vi) a TSP robot; and (vii) a TSP load/unload robot.
The TSP load conveyor is for carrying a test device inside a TSP load/unload region of a TSP testing subsystem. The TSP unload conveyor is designed to remove, from the TSP load/unload region of the TSP testing subsystem, the test device that passes testing inside the TSP testing subsystem. The TSP reject conveyor is for removing, from the TSP load/unload region of the TSP testing subsystem, the test device that fails testing inside the TSP testing subsystem.
Multiple TSP testing jigs are disposed between the TSP load conveyor and the TSP unload conveyor or the TSP reject conveyor. Each of the multiple TSP testing shuttles is designed to have one of the TSP testing jigs secured thereon, and is designed to displace a TSP testing jig, in the Y-direction, back and forth from the TSP load/unload region to a TSP test region (where TSP testing is carried out).
The TSP robot includes a stylus end effector and is designed to contact predetermined contact regions on the display screen of the test device for testing TSP functionalities of the test device.
The TSP load/unload robot, in a first operative state, transfers test device from the TSP load conveyor to one of the multiple TSP testing jigs. In a second operative state, the TSP load/unload robot transfers test device from one of the multiple TSP testing jigs to the TSP unload conveyor when test device passes testing inside the TSP testing subsystem. In a third another operative state, the TSP load/unload robot transfers test device from one of the multiple TSP testing jigs to the TSP reject conveyor when test device fails testing inside the TSP testing subsystem. The TSP load/unload robot, in each of these different operative states, traverses in the X-direction, from side-to-side, to load or unload test device inside the TSP load/unload region, for example, before and after testing inside the TSP subsystem. The TSP load/unload robot is different from, and not the same as the TSP robot.
The above-described automatic functional testing system may further include a test application controller that controls operation of a TSP robot controller and that provides TSP test applications to test TSP functionalities of the test device. The TSP robot controller may control operation of each of the TSP load/unload robot, the TSP robot and multiple TSP testing shuttles.
The above-mentioned TSP reject conveyor, preferably, extends in a direction that is perpendicular to a direction of extension of the TSP load conveyor or of the TSP unload conveyor. In preferred present arrangements and at one end of the TSP testing subsystem, the TSP load conveyor aligns with or is same as download unload conveyor that is part of a download testing subsystem. At the other end of the TSP testing subsystem, the TSP unload conveyor aligns with or is same as a camera load conveyor that is part of a camera testing subsystem.
In another aspect, the present teachings provide methods of automated functional testing. One exemplar method includes: (i) determining or receiving information whether TSP jig is vacant, wherein the TSP testing jig is present inside a TSP testing subsystem; (ii) determining, using a TSP load conveyor sensor, whether a test device is detected on a TSP load conveyor; (iii) placing, using a TSP load/unload robot, the test device on the vacant TSP testing jig to produce an occupied TSP testing jig, if the TSP testing jig is deemed to be vacant, and if the test device is detected on the TSP load conveyor; (iv) downloading, using a wireless connection and on the test device, one or more TSP test applications that are stored on a test application controller; (iv) testing, using one or more of the TSP test applications in conjunction with the TSP robot, TSP functionalities of the test device; and (v) generating a TSP test result, which indicates whether the test device passed or failed the testing TSP functionalities; (vi) conveying, using the TSP load/unload robot, the test device present at the occupied TSP testing jig to a TSP unload conveyor, if the TSP test result indicates that the test device passed testing of the TSP functionalities; and (vii) removing, using the TSP load/unload robot, the test device from the occupied TSP testing jig to a TSP reject conveyor, if the TSP test result indicates that the test device failed testing of the TSP functionalities.
Each of the above-describe steps of conveying or removing may include; (i) moving a TSP testing shuttle from a TSP test region to a TSP load/unload region, wherein the TSP testing jig is secured on the TSP testing shuttle; (ii) picking up, using the TSP load/unload robot, the test device from the TSP testing jig; and (iii) displacing the TSP load/unload robot in the X-direction and away from the TSP test region.
Testing TSP functionalities of the test device includes, for example, testing one without-axis functionality, which may be one functionality chosen from a group comprising wireless connection-related functionality, short range wireless interconnection-related functionality, and charging functionality of the test device. The term, “without-axis functionality.” as used herein, refers to functionalities that do not require linear movement of the test device along any of X-direction, Y-direction and Z-direction.
During testing of TSP functionalities, the present automated functional testing methods may draw, using a stylus robot, a pattern on the display screen of the test device. To create this pattern, the method includes a step of moving the stylus robot in X-direction, Y-direction and Z-direction. This pattern is drawn when the stylus contacts the test device undergoing TSP testing, and one or more of the TSP test applications are active on the test device.
In accordance with one embodiment of the present teachings, testing TSP functionalities of the test device includes testing three-dimensional functionalities. In this test, the stylus robot displaces in X-direction, Y-direction and Z-direction. The displacement of the stylus in Z-direction is, preferably, accompanied by the following steps: (i) contacting, using the stylus robot, one or more predetermined contact regions on the display screen of the test device, (ii) applying varying amount of pressure on each of one or more of the predetermined contact regions; and (iii) evaluating an amount of light emitted through the display screen under varying amount of pressure. One or more of the predetermined contact regions are scattered on the display device so that different parts of the displays screen are tested during the testing TSP functionalities.
Once testing of TSP functionalities is complete, the present automated functional testing methods contemplate, using the test application controller, to providing the TSP test results from the TSP robot controller to the TSP load/unload robot. This triggers the TSP load/unload robot to be informed on whether to unload the test device (which has passed TSP testing) on the TSP unload conveyor so that the test device is advanced for further testing, or to remove the test device (which has failed TSP testing), using the TSP reject conveyor, from the TSP testing, subsystem.
After TSP testing is successfully completed, the present automated functional testing methods, preferably, include a step of testing camera functionalities of the test device, in a camera testing subsystem. As a result, prior to camera testing, the present methods may include conveying the test device to a TSP unload conveyor, which removes the test device from the TSP testing subsystem.

The term, “with-axis functionality,” as used herein, refers to functionalities that require movement, e.g., along X-direction, Y-direction and/or Z-direction, of the test device. In certain preferred embodiments of the present teachings, the above-described method of automated functional testing may further include performing download testing prior to the determining or the receiving information whether download testing jig is vacant. This step of performing includes: (i) determining or receiving information whether a download testing jig is vacant, wherein the download testing jig is present inside a download testing subsystem; (ii) determining, using a download load conveyor sensor, whether a test device is detected on a download load conveyor; (iii) placing, using a download load/unload robot, the test device on the vacant download testing jig to produce an occupied download testing jig, if the download testing jig is deemed vacant, and if the test device is detected on the download load conveyor; (iv) introducing, using a download robot, a download test application connector inside a test application receiving port on the test device to form a download test application connection (e.g., USB® connection); (v) downloading on the test device, using the download test application connection, one or more download test applications stored on a download test application controller, which is different from the test application controller; (vi) testing download functionalities of the test device, using the download test application controller in conjunction with one or more of the download test applications (e.g., wireless connection profile) stored on the test device; (vii) generating a download test result, which indicates whether the test device passed or failed the testing download functionalities; (viii) conveying, using the download load/unload robot, the test device present at the occupied download testing jig to a download unload conveyor, if the download test result indicates that the test device passed testing of the download functionalities; and (ix) removing, using the download load/unload robot, the test device from the occupied download testing jig to a download reject conveyor, if the download test result indicates that the test device failed testing of the download functionalities.

In the third operative state, the camera load/unload robot transfers test device from one of the multiple camera testing jigs to the camera reject conveyor when test device fails testing inside the camera testing subsystem. The camera load/unload robot, in these different operative states, traverses in X-direction, from side-to-side, to load or unload the test device, for example, before and after testing inside the camera subsystem. In such systems, the camera load/unload robot is different from, and not the same as, the camera robot.

One exemplar process includes: (i) loading, using a download loading/unloading robot, a test device on a download testing jig present inside a download testing subsystem; (ii) installing on the test device, using a download robot including a download test application connector, a wireless connection profile that enables a wireless connection between the test device and a test application controller; (iii) conveying, using the download loading/unloading robot and a touch screen panel (“TSP”) loading/unloading robot, the test device from the download testing subsystem to a TSP testing subsystem; (iv) launching, using the test application controller, the wireless connection profile on the test device present inside the TSP testing subsystem to establish a wireless connection between the test device and the test application controller; and (v) retrieving, using the wireless connection, from the test device a device identification code of the test device. A communications network, such as the Global Systems for Mobile Communications (“GSM”) network, uses the device identification code (i.e., International Mobile Equipment Identity (“IMEI”) number) to identify the test device and to cease unauthorized use of the test device in an operational state.
Preferred embodiments of the present automated functional testing methods include introducing, using a TSP robot, a TSP test application connector inside a test application receiving port on the test device to form a TSP test application connection. In this embodiment, the above-described launching step includes using the TSP test application connection in conjunction with the test application controller and the step of introducing is carried out before the step of launching is carried out.
In those instances where an operating system is not downloaded on to the device prior to the above-described installing step, the present automated functional testing methods, preferably, further include downloading, using the download test application connector, on the test device one or more download test applications (which are different from the wireless connection profile) and/or an operating system. Both the operating system and download testing applications are stored on a download test application controller, which is different from the test application controller. Further, the download unload/load robot is different from the download robot. If the above-described downloading step is performed, it is performed before or at the same time as the above-described installing step is carried out.

This allows tracking results of different types of functional testing for a particular test device to be associated with the device identification code of that test device. By way of example, the present automated functional testing methods includes; (i) testing, using a TSP robot, TSP functionalities of the test device; (ii) obtaining, using the test application controller, TSP test results of the test device generated from testing of TSP functionalities; and (iii) associating and storing, using the test application controller, the TSP test results of the test device with the device identification code of the test device.

Arrangement of such regions also contributes to realization of higher throughput values, of processed test devices, for the present systems and methods than those realized by conventional testing methods. In the present arrangements, a download load/unload robot 224, preferably, displaces in the X-direction and rapidly loads test devices (e.g., one test device 225 at a time) from download load conveyor 222 to download loading/unloading region 522.

Test devices in reject box may undergo repair to fix one or more of the defects identified during download testing.

Test devices in reject box may undergo repair to fix one or more of the defects identified during TSP testing.

Although not necessary, camera testing subsystem 260 may have defined therein a camera loading/unloading region 562 and a camera testing region 568. Arrangement of such regions contribute to realization of higher throughput values of test devices that undergo camera testing. In the present arrangements, a camera load/unload robot 264, preferably, displaces in the X-direction and rapidly loads, one test device 265 at a time, from camera load conveyor 262 to camera loading/unloading region 562. Before camera testing commences, however, camera testing shuttle 268 displaces camera testing jig 266 in the Y-direction. With test device 265 secured thereon and with the help of camera testing shuttle 268, camera testing jig 266 may specifically displace from camera loading/unloading region 562 to camera test region 568, where camera testing on test device 265 is carried out.

In certain embodiments of the present arrangements, a camera reject conveyor 272 is provided to remove, from camera testing subsystem 260, test devices that fail camera testing. In preferred embodiments of these arrangements, camera reject conveyor 272 extends substantially perpendicular to camera unload conveyor 270.

Inside audio testing subsystem 280 shown in
Although not necessary, audio testing subsystem 280 may have defined therein an audio loading/unloading region 582 and an audio testing region 588. Arrangement of such regions contributes to realization of higher throughput values of test devices that undergo audio testing. In the present arrangements, audio load/unload robot 284, preferably, displaces in the X-direction and rapidly loads, one test device 285 at a time, from audio load conveyor 282 to audio loading/unloading region 582. Before audio testing commences, however, audio shuttle 288 displaces audio testing jig 286 in the Y-direction. With test device 285 secured thereon, audio testing jig 286 may specifically displace from audio loading/unloading region 582 to audio testing region 588, where audio testing on test device 285 is carried out. After audio testing is complete, audio shuttle 288, preferably, facilitates return of audio testing jig 286 from audio testing region 588 to audio loading/unloading region 582. From there and depending on its audio test results, test device 285 is disposed. By way of example, if test device 285 passes the audio test, then audio load/unload robot 284 advances test device 285 from audio loading/unloading region 582 to audio unload conveyor 290 for further testing.
In certain embodiments of the present arrangements, audio reject conveyor 292 is provided to remove, from audio testing subsystem 280, test devices that fail audio testing. In preferred embodiments of these arrangements, audio reject conveyor 292 extends substantially perpendicular to audio unload conveyor 290. If test device 285 fails the audio test, then audio load/unload robot 284 conveys test device 285 from audio loading/unloading region 582 to audio reject conveyor 292, which carries it to a reject box that may be an external attachment of audio testing subsystem 280. Test devices in reject box may undergo repair to fix one or more of the defects identified during audio testing.
In an automated implementation of audio testing subsystem 280, testing using audio robot 302 is accompanied by having one or more audio test applications on test device 285′ as shown in
Regardless of the manner in which camera test applications are downloaded, installed and launched on test device 285′, testing by audio robot 302′ of
Although it is not necessary that the camera testing subsystem is disposed prior to the audio testing subsystem as shown in, for example,
As described above, during TSP testing, TSP robot 255′ shown in
Such displacement of the robots, testing shuttles, load conveyors, unload conveyors, and load/unload robots is, preferably, accomplished using an AC motor and belt or ball and screw arrangement. Displacement in the X-direction by a loading/unloading robot, for example, may include an AC servo-motor and timing belt arrangement that allows displacement of the test device “side-to-side.” Displacement in the Z-direction by a camera or audio testing robot may include an AC servo-motor ball and screw arrangement that allows displacement of the test device “up and/or down.” In accordance with one embodiment of the present teachings, displacement in the X-direction of the AC servo-motor is macroscopic, but displacement in the Z-direction of the other AC servo-motor (with ball and screw) is microscopic for precise positioning. An exemplar value of a stroke of the AC servo-motor displacing in the X-direction may be about 1,500 mm and an exemplar value of a stroke of the AC servo-motor displacing in the Z-direction may be about 40 mm. Testing shuttles, deployed in the different testing subsystems, may include a load less cylinder that have an exemplar stroke value of 200 mm.
By way of example, TSP robot 255′, as shown in
As another example, loading/unloading robot, deployed in the different testing subsystems, include an AC servo-motor and timing belt to allow displacement of the test device in the X-direction and include an AC servo-motor, ball and screw to allow displacement of the test device in the Z-direction. The AC servo-motor that allows for displacement in the X-direction has an exemplar stroke value of about 1,200 mm and the AC servo-motor that allows for displacement in the Z-direction has an exemplar stroke value of about 40 mm. Audio box 299 may include a load less cylinder operation that has an exemplar stroke value of about 300 mm. Regardless of whether a timing belt or a ball and screw are used, the AC servo-motor operates under the action of a control scheme to provide the requisite displacement.
Distributed control scheme 600 uses two different controllers, a download test application controller 601 and a test application controller 608 to control operations of the different robots and jigs shown in
Test application controller 608 controls operation of each of a TSP robot controller 602, a camera robot controller 604, and an audio robot controller 606. Preferably, a standard RS-232C bi-directional and serial connection between test application controller 608 and each of robot controllers 602, 604, and 606, allows effective exchange regarding status and control instructions. Preferably, a 24-volt on/off switch signal allows communication between download robot controller 603 and TSP robot controller 602, TSP robot controller 602 and camera robot controller 604, and camera robot controller 604 and audio robot controller 606. Accomplishing coordinated operation within automated functional testing system 100 shown in
TSP robot controller 602 controls displacement and operations of a TSP load/unload robot (e.g., TSP load/unload robot 244 shown in
Camera robot controller 604 controls displacement and operations of a camera load/unload robot (e.g., camera load/unload robot 264 shown in
Audio robot controller 606 controls displacement and operations of an audio load/unload robot (e.g., camera load/unload robot 284 shown in
As will be explained later in connection with
In this linear configuration that extends in the X-direction, the load/unload robots in each of the subsystems (e.g., download load/unload robot 224 of
The present arrangements and teaching not only offer high throughput, but also streamline the test results obtained from testing conducted inside each subsystem. Specifically, the test results are identified by a device identification code that is associated with the test device. In one embodiment of the present teachings, an International Mobile Equipment Identity (“IMEI”) number of a device is retrieved from the test device and the different test results are associated with this IMEI number and stored. The IMEI number is a unique identification or serial number, typically 15 digits long that identifies a smart phone or mobile device, and has no relation to its user or subscriber. The IMEI number is used by Global Systems for Mobile Communications (“GSM”) network to identify valid devices and may be used for preventing a stolen smart phone or mobile device from accessing the network. For example, if a mobile phone is stolen, the owner may call their network provider and instruct them to blacklist the phone using its IMET number.
The present teachings recognize, however, that associating test results of a test device with its IMEI number or some other similar type of device identification code has many advantages. For example, a test and repair history of the test device may be developed, maintained and made available to a network, user or subscriber when needed. As another example, a manufacturer of the test devices may correlate the defects identified during testing with specific lots (of test devices) based on the IMEI numbers. This would allow manufactures to conduct certain analysis (e.g., trend analysis) and gain insight into obtaining high yields from the device manufacturing process.
In an operative state of the download robot controller 1512, download load/unload robot 1510 is instructed to load a test device present on a download load conveyor (e.g., download load conveyor 222 of
In another operative state of download robot controller 1512, download test application connector 1502 is instructed to engage with data/power receiving port of the test device to form download test application connection 1504. One or more download test applications, stored on download test application controller 1508, are downloaded on the test device using download test application connection 1504. In one embodiment of the present teachings, an operating system, preferably a recent version, is stored on download test application controller 1508 and downloaded on the test device, using download test application connection 1504, prior to downloading of one or more of the download test applications. In connection with
Each of these controllers is communicatively coupled to preferably a single test application controller 1658 through their respective bi-directional connections, i.e., connections 1664, 1666 and 1668. As explained in connection with
In accordance with one aspect, the present arrangements offer a unique and novel an audio testing subsystem. In an operative state, this subsystem tests different audio functions performed by test devices. In a preferred embodiment, an audio test assembly of the present arrangements includes an audio robot, which in an operative state actuates keys and/or buttons or probes components that are used in obtaining an audio signal or audio from the test device. The audio testing subsystem, in this preferred arrangement, also includes an audio robot controller, which in an operative state controls disposition of the audio robot and in conjunction with operation of the audio test applications facilitates test of audio functions performed by the test device.
Continuing with the preferred audio testing subsystem, the arrangement includes an audio box (e.g., audio box 299 of
In one embodiment, the present arrangements, e.g., as described in
The present teachings recognize that the conventional integrated control schemes are expensive and offer little or no flexibility. Specifically, in attempt to accomplish compatibility between the different control functionalities and different control components in the integrated control scheme approach, the functionalities and the components are sequenced in a particularly rigid manner. Further, the present teachings also recognize that one or few components that provide an integrated control approach are also relatively expensive. A user purchasing and employ the conventional control systems in a manufacturing facility, is bound to the seller of the integrated control scheme. The expense problem is further exacerbated when different models of test devices are introduced into the market and the control schemes and test sequencing needs modification to account for changes in the design and/or functionalities of the test device.
In sharp contrast, the distributed control schemes of the present arrangements do not stiffer from such drawbacks. Specifically, such distributed control schemes are relatively inexpensive over their integrated counterparts. Moreover, the distributed control schemes offer a significant flexibility to the manufacturer, who cam simplify reprogram the relevant ones of the control components to account for changes in the test sequence or implementing new tests. In other words, the rigid structure of sequencing different tests and reestablishing compatibility of all the different integrated functionalities and/or components encountered in the integrated control scheme approach, when introducing new features and/or tests, are avoided in the distributed control scheme approach of the present arrangements. In the distributed control scheme, when a new test model is introduced, for example, the relevant control functionalities and/or components that need modification are modified or if a new control component needs to be added, it is easily added to the existing distributed control scheme. The manufacturer, who implements the distributed control scheme of the present arrangements, is also not at the mercy of a single seller (as in the integrated controls scheme) of the control scheme because he can purchase the different control components from other parties.
More importantly, the distributed control scheme allows different test functionalities to be implemented inside different subsystems at the same time. This represents a marked improvement over the conventional integrated control schemes because the present arrangements yield a significantly higher throughput of the tested test devices over those obtained from conventional schemes. By way of example, in an integrated control scheme approach it is common to conduct a certain type of camera testing and audio testing in the same chamber and the noise made by movement of test robot routinely interferes with an adjacent audio box, inside which a test device is undergoing audio testing. Audio results or audio signals obtained from such interference do not provide meaningful and/or reliable results for the test. Again, in sharp contrast, the distributed control scheme of the present arrangement allows different subsystems to be used such that one is dedicated to camera testing and another to audio testing and any noise emanating from camera robot movement does not interfere with an audio box disposed inside an audio subsystem, which is a different chamber from the chamber that is part of the camera subsystem. Thus, the audio test results produced from audio testing according to the present teachings is meaningful and reliable.
Next, a step 1704 may include downloading an operating system on the test device. In accordance with one embodiment of the present teachings, preferably a recent version of an operating system that is stored on a download test application controller (e.g, download test application controller 1508 of
Step 1704 is an optional step and is not necessary according to the present teachings. In certain embodiments of the present teachings, after step 1702, process 1700 proceeds directly to step 1706, if an operating system was installed in test device prior to step 1702.
Then, a step 1706 includes downloading a download test application on the test device. In accordance with one embodiment of the present teachings, one or more download test applications stored on a download test application controller (e.g., download test application controller 1508 of
After step 1706 concludes, another step 1708 is carried out. This step involves installing a wireless connection (e.g., WiFi® connection) profile on the test device. The installation of the wireless connection profile is designed to enable a wireless connection between the test device and a test application controller (e.g., test application controller 1658 of
In an optional implementation, process 1700 then proceeds to a step 1710, in which the test device is conveyed from a download testing subsystem (e.g., downloading subsystem 120 of
Next, step 1708 includes launching, through the wireless connection, a test application on the test device using the test application controller (e.g., test application controller 1658 of
Then, step 1710 is performed and includes retrieving a device identification code (e.g., an IMEI number) of the test device. By way of example, test application controller 1658 of
If the TSP testing jig is deemed to be vacant, and if the test device is detected on the TSP load conveyor, then method 1100 proceeds to step 1106. This step includes placing the test device on the vacant TSP testing jig to produce an occupied TSP testing jig. Step 1106 is performed using a TSP load/unload robot (e.g., TSP load/unload robot 244 of
With the test device present on the TSP testing jig, step 1108 is carried out. This step includes downloading, using a wireless connection (e.g., wireless connection shown between test devices 645 and test application controller 604 shown in
Next, step 1112 includes generating a TSP test result, which indicates whether the test device passed or failed the testing of TSP functionalities. If the TSP test result indicates that the test device passed the testing of TSP functionalities, then method 1100 advances to step 1114. This step involves conveying the test device present at the occupied TSP testing jig to a TSP unload conveyor (e.g., TSP unload conveyor 250 shown in
Method of TSP testing 100, preferably, includes testing using multiple TSP testing jigs to achieve greater throughput of tested devices using the present TSP testing methods. Under this approach, the method includes: (i) determining or receiving information whether one or more of multiple TSP testing jigs (which are present inside the TSP testing subsystem) are vacant; (ii) determining, using the TSP load conveyor sensor, whether one or more of the multiple test devices are detected, one the test device at a time, on the TSP load conveyor; and (iii) placing, using the TSP load/unload robot, the multiple test devices, one the test device at a time, on the multiple vacant TSP testing jigs until the multiple vacant TSP testing jigs are filled and the multiple test devices fill the multiple vacant TSP testing jigs to produce multiple occupied TSP testing jigs inside the TSP testing subsystem.
Once all the multiple vacant TSP testing jigs are filled, then testing of TSP functionalities, at the different TSP testing jigs, may be simultaneously carried out. To this end, method of TSP testing 1100, preferably, further includes testing simultaneously TSP functionalities of the multiple test devices after the multiple occupied TSP testing jigs are produced inside the TSP testing subsystem.
Another preferable step, in method of TSP testing 1100 includes placing, using same the TSP load/unload robot, another test device on the vacant TSP testing jig after the steps of either conveying or removing vacate the TSP testing jig by unloading the test device therefrom. In other words, when a TSP load/unload robot vacates a TSP testing jig, then the same TSP load/unload robot, preferably, places another test device on the vacant TSP testing jig.
Next, a step 1204 includes downloading, a download test application, on the test device. In accordance with one embodiment of the present teachings, one or more download test applications stored on a download test application controller (e.g., download test application controller 1508 of
After step 1204 concludes, a step 1206 is carried out. This step involves installing a wireless connection profile on the test device and is substantially similar to step 1708 of
Next, method 1200 advances to a step 1210, which includes launching, through the wireless connection, at least one of the download test applications, on the test device present inside the TSP testing subsystem. Step 1210 is performed using the test application controller (e.g., test application controller 1658 of
Then, a step 1212 is performed and includes retrieving a device identification code (e.g., an IMEI number) of the test device and is substantially similar to step 1714 of
After the device identification code of the test device is retrieved, it may be stored on the test application controller. Regardless of whether the device identification code is stored or not, the test device present inside the TSP testing subsystem is ready for testing. To this end, a step 1214 includes testing TSP functionalities of the test device. In a next step, step 1216, TSP test results of the test device are obtained. Finally, in a step 1218 and, preferably, using the test application controller, the TSP test results obtained for the test device are associated with its device identification code and stored on the test application controller.
If the camera testing jig is deemed to be vacant, and if the test device is detected on the camera load conveyor, then method 1300 proceeds to step 1306. This step includes placing the test device on the vacant camera testing jig to produce an occupied camera testing jig. Step 1306 is performed using a camera load/unload robot (e.g., camera load/unload robot 264 of
With the test device present on the camera testing jig, step 1308 is carried out. This step includes downloading, using a wireless connection (e.g., wireless connection shown between test devices 645 and test application controller 604 shown in
Next, step 1312 includes generating a camera test result, which indicates whether the test device passed or failed the testing of camera functionalities. If the camera test result indicates that the test device passed the testing of camera functionalities, then method 1300 advances to step 1314. This step involves conveying the test device present at the occupied camera testing jig to a camera unload conveyor (e.g., camera unload conveyor 270 shown in
Method of camera testing 1300 may further include: (i) determining or receiving information whether one or more of multiple camera testing jigs (which are present inside the camera testing subsystem) are vacant; (ii) determining, using the camera load conveyor sensor, whether one or more of the multiple test devices are detected, one the test device at a time, on the camera load conveyor; and (iii) placing, using the camera load/unload robot, the multiple test devices, one the test device at a time, on the multiple vacant camera testing jigs until the multiple vacant camera testing jigs are filled and the multiple test devices fill the multiple vacant camera testing jigs to produce multiple occupied camera testing jigs inside the camera testing subsystem.
After multiple camera testing jigs are filled, camera testing may commence such that test devices, in each of the camera testing jigs, are simultaneously tested for camera functionalities. To this end, the above-described methods further include testing simultaneously camera functionalities of the multiple test devices after the multiple occupied camera testing jigs are produced inside the camera testing subsystem.
The above-described methods may further include placing, using same the camera load/unload robot, another test device on the vacant camera testing jig after the step of conveying or the step of removing, both of which vacate the camera testing jig by unloading the test device therefrom.
After the device identification code of the test device is retrieved in step 1412, method 1400 advances to a step 1414, which includes testing camera functionalities of the test device. In a next step, step 1416, camera test results of the test device are obtained. Finally, in a step 1418 and, preferably, using the test application controller, the camera test results obtained for the test device are associated with its device identification code and stored on the test application controller.
If the audio testing jig is deemed to be vacant, and if the test device is detected on the audio load conveyor, then method 1800 proceeds to step 1806. This step includes placing the test device on the vacant audio testing jig to produce an occupied audio testing jig. Step 1806 is performed using an audio load/unload robot (e.g., audio load/unload robot 284 of
With the test device present on the audio testing jig, step 1808 is carried out. This step includes downloading, using a wireless connection (e.g., wireless connection shown between test devices 645 and test application controller 604 shown in
Next, step 1812 includes generating an audio test result, which indicates whether the test device passed or failed the testing of audio functionalities. If the audio test result indicates that the test device passed the testing of audio functionalities, then method 1800 advances to step 1814. This step involves conveying the test device present at the occupied audio testing jig to an audio unload conveyor (e.g., audio unload conveyor 290 shown in
Method of audio testing 1800 may further include: (i) determining or receiving information whether one or more of multiple audio testing jigs (which are present inside the audio box of the audio testing subsystem) are vacant; (ii) determining, using the audio load conveyor sensor, whether one or more of the multiple test devices are detected, one the test device at a time, on the audio load conveyor; and (iii) placing, using the audio load/unload robot, the multiple test devices, one the test device at a time, on the multiple vacant audio testing jigs until the multiple vacant audio testing jigs are filled and the multiple test devices fill the multiple vacant audio testing jigs to produce multiple occupied audio testing jigs inside the audio testing subsystem.
After multiple audio testing jigs are filled, audio testing may commence such that test devices, in each of the audio testing jigs, are simultaneously tested for audio functionalities. To this end, method of audio testing 1800 further includes testing simultaneously audio functionalities of the multiple test devices after the multiple occupied audio testing jigs are produced inside the audio testing subsystem.
Method of audio test 1800 may further include placing, using same the audio load/unload robot, another test device on the vacant audio testing jig after the step of conveying or the step of removing, both of which vacate the audio testing jig by unloading the test device therefrom.
After the device identification code of the test device is retrieved in step 1612, method 1600 advances to a step 1614, which includes testing audio functionalities of the test device. In a next step, step 1616, audio test results of the test device are obtained. Finally, in a step 1618 and, preferably, using the test application controller, the audio test results obtained for the test device are associated with its device identification code and stored on the test application controller.
