The sixth driver 241 drives the two horizontal connecting members 243 to open along the Y axis until the pressing block 242 presses on the tablet computer. Then, the seventh driver 71 drives the USB plug 72 to move along the F1 direction of the X axis, thereby driving the USB plug 72 to be inserted into the USB socket, so as to perform a USB module test. After the test is completed, the seventh driver 71 drives the USB plug 72 to move in the opposite direction of the F1 direction, thereby driving the USB plug 72 to be unplugged from the USB socket; then, the magnetic induction performance of the tablet computer is tested by the magnet 91; then, the first driver 31 drives the test probe 32 to move in the F3 direction of the Y axis, so that the test probe 32 contacts the conductive contact, thereby performing a conductive module test. After the test is completed, the first driver 31 drives the test probe 32 to move in the opposite direction of the F3 direction, so that the test probe 32 is away from the conductive contact; then, the second driver 41 drives the test pressure head 42 to move in the opposite direction of the F3 direction of the Y axis. The test head 42 moves in the direction of the X-axis F1, thereby causing the test head 42 to press the key, thereby performing a key test. After the test is completed, the second driver 41 drives the test head 42 to move in the F3 direction, thereby causing the test head 42 to move away from the key; then, the test plug 52 is driven by the third driver 51 to move in the opposite direction of the X-axis F1 direction, thereby driving the test plug 52 to be inserted into the audio jack, thereby performing an audio module test. After the test is completed, the third driver 51 drives the test plug 52 to move in the F1 direction, thereby driving the test plug 52 to be pulled out of the audio jack, and drives the test plug 52 to rotate a certain angle through the rotation driver 541; then, the test module 52 is driven by the third driver 51 to move in the F2 direction, thereby causing the test plug 52 to be pulled out of the audio jack, and drives the test plug 52 to rotate a certain angle through the rotation driver 541; The fourth driver 61 drives the lighting unit 62 to move in the opposite direction of the X-axis F1 direction to get closer to the tablet computer, so as to test the photosensitivity of the tablet computer. After the test is completed, the fourth driver 61 drives the lighting unit 62 to move in the F1 direction; then, the sound signal of the tablet computer is obtained through the microphone 81 to test the SPK performance; then, the six driver 241 drives the two horizontal connecting members 243 to retract along the Y-axis to link the connecting rod 244 to move the pressing block 242 away from the tablet computer, and then the fifth driver 231 drives the pushing member 232 to move in the direction away from the tablet computer; finally, the tablet computer is removed from the positioning fixture 2.

[0059] Of course, the test steps of each test mechanism of the tablet computer testing machine 100 described above are only preferred implementations of the present invention. The test steps of each test mechanism can be adaptively adjusted according to actual test requirements, and even each test mechanism can be controlled to test various functional modules of the tablet computer at the same time, so it should not be limited to this.
