[0032] Step 3: The detection mechanism 3 performs a power-on test on the LED light source board, and the LED light source board is powered on and lights up;

[0033] Step 4: The detection mechanism 3 performs CCD detection, that is, records the state of the LED light source board to detect whether the LED light source board emits light normally;

[0034] Step 5: After the LED light source board passes the test, the baffle 203 and the side slide plate 202 return to their original positions, and the LED light source board is transported to the feeding mechanism 4 by the conveying mechanism.
