Meanwhile, the electric control telescopic rod 212 is started, and the electric control telescopic rod 212 drives the sorting plate 213 to abut against the guide plate 214, causing the sorting plate 213 to block the tablets on the guide plate 214. Then the stepping motor 211 is started, and the stepping motor 211 drives the screw rod 210 to rotate. The screw rod 210 drives the carriage 29 to move on the slide rail 28, causing the sorting plate 213 to drive the tablets to move beside the corresponding qualified (overweight, underweight) bins 215. The sorting plate 213 resets, causing the tablets to slide off the guide plate 214; As the tablets slide off the guide plate 214, the tablets fall into the discharge limit slot 37. The discharge limit slot 37 sends the tablets into the receiving tray 32. The camera 36 is started, and the camera 36 takes pictures of the tablets for judgment. When the tablets are not broken again, the second servo motor 35 is started, and the second servo motor 35 drives the rotating plate 34 to rotate, causing the tablets to fall from the receiving tray 32 into the bin 215. When the tablets are broken again, the first servo motor 33 is started, and the first servo motor 33 drives the receiving tray 32 to rotate, causing the receiving tray 32 to turn above the conveyor belt 310. The conveyor motor 311 is started, and the conveyor motor 311 drives the conveyor roller 39 to rotate. The conveyor roller 39 drives the conveyor belt 310 to rotate, causing the conveyor belt 310 to send the re-broken tablets into the bin 215 for placing broken tablets.
