[0086] As shown in Figure 2 , the last aluminum plate is conveyed to the position of the unloading station 7 through the annular conveying line 2. The unloading station 7 is composed of a carrying mechanism 8, a good product conveying line 72 and a defective product conveying line 71. The good product conveying line 72 and the defective product conveying line 71 are located below the carrying mechanism 8. The good products and defective products of the aluminum plates are conveyed to the good product conveying line 72 and the defective product conveying line 71 respectively through the carrying mechanism 8, and are conveyed out of the loop line by the two conveying lines.

[0087] As shown in Figure 27 , the structures of the good product conveying line 72 and the defective product conveying line 72 are similar to that of the feeding conveying line 31. The widths of the conveying lines are adjustable. The widths of the conveying lines are adjusted by the screw rod transmission. The good products of the aluminum plates need to be restacked after reaching the good product conveying line 72. Therefore, a lifting and pushing mechanism 722 is arranged in the middle of the good product conveying line 72. Three lifting assemblies 721 are arranged at the front end of the good product conveying line 72. Before the carrying mechanism 8 conveys the aluminum plates to the good product conveying line 72, the lifting assemblies 721 are lifted upward to receive the aluminum plates.

A plurality of through holes are arranged on the limiting plate, and a plurality of bearing blocks 7223 are formed on the side surface of the carrier. The lower side of the bearing block 7223 is a slope, and the two ends of the bearing plate 7221 are rotatably connected with the limiting plate. The bearing block 7223 passes through the through hole on the limiting plate and penetrates into the inner side of the limiting plate. The upper side of the bearing plate 7221 is connected with the limiting plate through the tension spring 7222, so that the bearing plate 7221 can be turned up when it is stressed, and it can return to its original state under the action of the tension spring 7222 when it is not stressed.

A pad 3137 is arranged on the top plate 3136. When the aluminum plate is conveyed to the position of the lifting and pushing mechanism 722 by the good product conveying line 72, the lifting cylinder 3135 will lift the aluminum plate upward through the top plate 3136. The aluminum plate will push against the bearing block 7223 during upward movement, and the carrier will be turned up under the cooperation of the slope of the bearing block 7223. In this way, the aluminum plate will be above the bearing block 7223, and the bearing plate 7221 will return to its original state under the action of the tension spring 7222. The top plate 3136 moves downward, and the aluminum plate can be smoothly placed on the bearing block 7223 on the two limiting plates. Repeating the above action can stack the aluminum plates from bottom to top into a pile, and then the pushing assembly pushes the aluminum plate to the rear half of the good product conveying line 72.

[0090] As shown in the figure, Figure 29 The pushing assembly is mainly composed of a support plate 3132, a support rod 7224 supporting the bottom of the support plate 3132, a pushing plate 7226 horizontally slidably connected with the support plate 3132, and a pushing cylinder 7225 arranged on the support plate 3132. The output end of the pushing cylinder 7225 is fixedly connected with the pushing plate 7226. The shape of the pushing plate 7226 is similar to L-shaped. The pushing plate 7226 is moved by the pushing cylinder 7225, and the aluminum plate is pushed to the rear half of the good product conveying line 72 by the pushing plate 7226, and then conveyed to the next process by the good product conveying line 72.
