Abstract

Apparatus and methods for automatically testing mobile devices are disclosed according to various embodiments. In one example, a disclosed apparatus includes: a robot having a retention device into which the mobile device to be tested is positioned; a test computer having a processor and a non-transitory computer readable storage medium storing test software for testing the mobile device; and a user monitor electrically connected to the test computer and configured for providing a result of the testing of the mobile device. The mobile device is wirelessly connected to the test computer and has a test application installed thereon corresponding to the test software. The robot is configured for performing interaction and manipulation of the mobile device in cooperation with the test application and the test software during the testing.

First claim

What is claimed is:

1. An apparatus for automatically testing a mobile device, comprising:
a robot having a retention device into which the mobile device to be tested is positioned;
a test computer having a processor and a non-transitory computer readable storage medium storing test software for testing the mobile device, wherein the mobile device is wirelessly connected to the test computer and has a single test application installed thereon and, in cooperation with the test software, is used to perform all of a plurality of tests such that at least one of the plurality of tests is being performed at the same time as another of the plurality of tests is being performed, wherein the robot is configured for performing interaction and manipulation of the mobile device in cooperation with the test application and the test software during the testing;
a scanner configured to scan a serial number of the mobile device and a slot number of a test chamber, and automatically start the testing of the mobile device after scanning the serial number and the slot number; and
a user monitor electrically connected to the test computer and configured for providing a result of the testing of the mobile device.

2. The apparatus of claim 1 , wherein:
the robot is a 7-axis robotic system having a robot arm; and
the robot arm has 4 degrees of freedom in the three-dimensional space.

3. The apparatus of claim 1 , wherein the interaction and manipulation of the mobile device performed by the robot comprise at least one of:
using a capacitive touch tip tool to make touchpoints on a screen of the mobile device;
moving a camera coupled on the robot to a location for the camera to take pictures of the screen of the mobile device when the screen is turned to different colors by the test application;
moving a tag near the mobile device to activate a sensor of the mobile device;
plugging an audio connector into an audio port of the mobile device;
picking up a magnetic tool to check a sensor of the mobile device; or
pushing each physical button on the mobile device for functionality test.

4. The apparatus of claim 1 , wherein:
the interaction and manipulation of the mobile device is performed by the robot while at least one test process is performed to test internal components and/or feature performances of the mobile device; and
the mobile device is at least one of: a smartphone, a smart watch, or a tablet.

5. The apparatus of claim 1 , further comprising:
a position calibration tool coupled to the robot and configured for determining positions of interfaces and physical buttons of the mobile device, based on positions of points on the retention device and a calibration software.

6. A method for automatically testing a mobile device, comprising:
loading a single test application on the mobile device positioned onto a retention device of a robot;
automatically wirelessly connecting the mobile device to a test computer having a processor and a non-transitory computer readable storage medium storing test software for testing the mobile device;
automatically starting the testing of the mobile device after scanning a serial number of the mobile device and a slot number of a device test chamber;
automatically manipulating the mobile device using the robot configured for interacting with the mobile device in cooperation with the test application and the test software;
automatically performing all of a plurality of tests of the mobile device based on the test application such that at least one of the plurality of tests is being performed at the same time as another of the plurality of tests is being performed; and
automatically sending a result of the testing of the mobile device to a user monitor electrically connected to the test computer and configured for displaying the result of the testing of the mobile device.

7. The method of claim 6 , wherein the automatically starting the testing of the mobile device comprises:
scanning, using a scanner, the slot number of the device test chamber housing the robot;
scanning, using the scanner, the serial number of the mobile device; and
associating the scanned serial number with the scanned slot number before the testing.

8. The method of claim 7 , further comprising:
automatically determining testing-related information of the mobile device based on the serial number of the mobile device, wherein the testing-related information comprises information about at least one of
an operation system of the mobile device,
locations of interfaces of the mobile device,
locations of cameras of the mobile device,
locations of physical buttons of the mobile device, or
features of the mobile device.

9. The method of claim 7 , further comprising:
positioning the mobile device onto the retention device of the robot;
selecting the slot number via the test application to start testing; and
automatically releasing a magnetic lock on a door of the device test chamber after the testing is completed.

10. The method of claim 7 , further comprising:
automatically monitoring, by a camera that is located in the device test chamber and connected to a sanity monitor outside the device test chamber, a process of the automatically testing.

11. The method of claim 6 , wherein the automatically testing comprises:
automatically testing, based on the test application, a touchscreen of the mobile device using a capacitive touch tip tool coupled to the robot; and
automatically testing, based on the test application, a proximity sensor of the mobile device using the capacitive touch tip tool.

12. The method of claim 6 , wherein the automatically testing comprises:
automatically testing, based on the test application, a back camera of the mobile device by based on predetermined images;
automatically turning over the mobile device by rotating the retention device; and
automatically testing, based on the test application, a front camera of the mobile device based on the predetermined images.

13. The method of claim 12 , wherein the predetermined images comprise:
a colorful patterned image and a white blank image.

14. The method of claim 6 , wherein the automatically testing comprises:
automatically plugging an audio connector coupled to the robot into an audio port of the mobile device; and
automatically testing, based on the test application, a speaker of the mobile device via the audio connector.

15. The method of claim 6 , wherein the automatically testing comprises:
automatically generating a sound by a speaker coupled to the robot; and
automatically testing, based on the test application, a microphone of the mobile device using the sound.

16. The method of claim 6 , wherein the automatically testing comprises:
automatically pushing, using a mechanical finger coupled to the robot based on the test application, each physical button on the mobile device for functionality test;
automatically taking, by a camera coupled to the robot, pictures of a screen of the mobile device when the screen is turned to different colors based on the test application; and
automatically analyzing the pictures while other tests are being performed on the mobile device.

17. A system for automatically testing mobile devices, comprising:
