[0025] Specifically, the operation of the motor A 8 drives the shaft A 81 to rotate, thereby driving the tooth block A 82 to rotate, so that the meshed tooth block B 61 moves, thereby driving the sliding plate 6 to move. The pushing plate 62 contacts the keyboard backlight sheet to push for feeding. Subsequently, the motor A 8 rotates reversely to drive the tooth block A 82 to rotate, so that the meshed tooth block B 61 moves in the reverse direction, and the pushing plate 62 moves in the reverse direction, ensuring that there is no interference when the subsequent keyboard backlight sheet is fed onto the conveyor belt 72, realizing automatic feeding and improving work efficiency. The detection box 21 is a CX-2600 / 6100 two-dimensional imaging type luminance meter.
