There are two roller conveyor lines 3 and lifting mechanisms 4, and the two lifting mechanisms 4 are arranged in mirror images of each other.

[0018] Reference Figure 2 The lifting mechanism 4 includes a lifting bracket 401, a lifting motor 403 and a sprocket group 404 are arranged on the top of the lifting bracket 401, a lifting slide rail 410 is arranged on one side of the lifting bracket 401, a lifting bracket 402 is arranged on the slider of the lifting slide rail 410, and a transmission chain is arranged on the sprocket group 404, one end of the transmission chain is connected to the lifting bracket 402, and the other end is arranged on the output shaft of the lifting motor 403.

[0019] The lifting bracket 402 is installed with a rotating shaft 405, a support plate 408 is installed at the upper end of the rotating shaft 405, a crank arm 406 is installed at the lower part of the rotating shaft 405, and a steering cylinder 407 is installed on the lower surface of the lifting bracket 402. The cylinder body of the steering cylinder 407 is hinged to the lifting bracket 402, and the piston rod is hinged to the crank arm 406; according to the stroke of the steering cylinder 407, its connection point on the crank arm 406 is adjusted so that the piston rod of the steering cylinder 407 is extended to drive the support plate 408 to rotate 90°. An annular track 409 is provided on the lifting bracket 402, and rollers compatible with the annular track 409 are installed on the support plate 408 to provide support for the support plate 408 so that it can rotate smoothly on the lifting bracket 402.

[0020] The three-axis manipulator 2 is provided with a gripper 5. Figure 3 The clamping jaw 5 includes a support plate 501, a guide rod 502, a lever-type travel switch 506 and two clamping cylinders 503 are arranged on the lower surface of the support plate 501, the lever-type travel switch 506 is arranged on one side of the support plate 501, and two support arms 504 are slidably installed on the guide rod 502. The two support arms 504 are mirror images of each other and are respectively connected to the piston rods of the two clamping cylinders 503, and an L-shaped clamping plate 505 is arranged at the lower end of the support arm 504.

[0021] In order to facilitate the understanding of the present invention, the following Figure 1 - Figure 3 The working principle of this solution is described in detail:

[0022] First, the aluminum ingot tray 6 is placed on the support plate 408 by a forklift, and the length direction of the aluminum ingot on it is parallel to the roller conveyor line 3. Then the three-axis manipulator 2 drives the clamping jaw 5 to move to one side of the aluminum ingot tray 6. In the process of moving to the aluminum ingot tray 6, the lever-type travel switch 506 first contacts the aluminum ingot on the aluminum ingot tray 6. The signal output by the lever-type travel switch 506 controls the clamping jaw 5 to continue to move to the top of the aluminum ingot through delay control. The support arm 504 of the clamping jaw 5 slides toward each other along the guide rod 502 under the drive of the clamping cylinder 503, thereby driving the L-shaped clamping plate 505 to clamp the aluminum ingot. Then the three-axis manipulator 2 moves the aluminum ingot to the roller conveyor line 3, which transports the aluminum ingot to the aluminum melting furnace.

[0023] After the aluminum ingots on the upper layer of the aluminum ingot tray 6 are grabbed, the piston rod of the steering cylinder 407 extends or retracts, driving the crank arm 406 and the rotating shaft 405 to rotate, and then driving the support plate 408 to rotate 90°, so that the length direction of the aluminum ingots on the lower layer is parallel to the roller conveyor line 3, and at the same time, the lifting motor 403 drives the lifting bracket 402 to rise to a certain height, which is convenient for the three-axis manipulator 2 to grab; the horizontal position of the aluminum ingots on the aluminum ingot tray 6 is judged by the lever-type travel switch 506 of the clamp 5, and the lifting motor 403 keeps the vertical position of the aluminum ingot unchanged, avoiding the three-axis manipulator 2 from positioning the aluminum ingot in the height direction, and the two cooperate with each other to achieve effective positioning and grabbing of the aluminum ingots. Compared with the mechanical vision positioning structure, it is simple, easy to maintain and has a low manufacturing cost. The two sets of roller conveyor lines 3 and the lifting mechanism 4 ensure continuous feeding, effectively ensuring the continuity of production and the continuous operation capability of the system in the event of a single-line failure.

[0024] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
