S3, the computer compares the measured power data with the standard power to judge whether the display to be measured is qualified; if qualified, go to step S4; if not, executing step S5;
in the embodiment of the present invention, step S4 is to test the display to be tested after the set delay time except that this judges ineligible, and the computer judges that the data of electric quantity measuring instrument can be read here after ineligible to judge again, in order to avoid the erroneous judgement.
S4, the computer sends a release signal, the MCU and the stopper control module control the stopper to be opened, and the display to be tested flows into the next station;
and after the computer judges that the display is qualified, sending a reminding display signal to the display, if the display is qualified.
S5, the computer sends a clamping signal, the MCU and the stopper control module control the stopper to be closed, and the operator makes unqualified marks and then performs maintenance treatment;
and after the computer judges that the display is unqualified, a reminding display signal is also sent to the display, such as 'the display is unqualified'.
Furthermore, the preset qualification judgment standard also comprises a standard current, the test current meets the standard current, the test power meets the standard power, and the display to be tested is qualified. The condition that the test current accords with the standard current is that the test current is not zero, but the leakage current is generally very small, the electric quantity measuring instrument is not easy to detect that the test current is not zero and is not beneficial to the operation judgment of a computer, so the condition of the standard current is more than 0.0002A, and when the detected current of the display to be tested is more than 0.0002A and the test power accords with the standard power, the display to be tested is qualified.
