[0034] The specific working principle is as follows. During operation, the conveying mechanism transports the light guide plate to between the upper and lower corresponding cutting knives 71 and lower cutting knives 72. Usually, the water inlet 301 on the light guide plate is vertically downward, and the side with the water inlet 301 is the rear side. When the front side enters between the upper cutting knife 71 and the lower cutting knife 72, the water inlet 301 is located in the groove 41 on the back of the lower knife seat 721 and the lower pressure plate 4. During punching, the servo electric cylinder 5 drives the upper pressure plate 2 downward, and the upper pressure plate 2 drives the upper cutting knife 71 and the pre-pressing mechanism 8 connected thereto to move downward synchronously. The bottom surface of the pressure block 82 on the pre-pressing mechanism 8 first contacts the top surface of the light guide plate and presses the light guide plate. The bottom surface of the light guide plate is located on the cutting edge of the lower cutting knife 72. When the upper pressure plate 2 continues to move downward, it will drive the upper cutting knife 71 to cooperate with the lower cutting knife 72 to cut the light guide plate, and the cut light guide plate sheet 300 falls along the blanking tray 200 to realize the cutting of the water inlet 301.

[0035] This light guide plate nozzle cutting mechanism can realize automatic cutting of the light guide plate, and can improve the cutting efficiency of the nozzle 301 on the light guide plate. The upper cutting knife 71 and the lower cutting knife 72 corresponding to the upper and lower cutting knives can ensure the cutting effect of the light guide plate, ensure the flatness of the cut after the light guide plate is cut, and improve the yield rate of the product. Moreover, by replacing the upper cutting knife 71 and the lower cutting knife 72 of different lengths, it can adapt to the cutting of the nozzle 301 on the light guide plates of different sizes. It has strong adaptability, is easy to operate, and improves the processing efficiency of the product.
