[0022] The first support 9 is provided on the mail conveying belt 4, and the 3D camera 6, the bottom surface code scanning camera 11 and the side surface code scanning camera 7 are arranged on the first support 9. The first support 9 comprises two first vertical rods 91 symmetrically arranged on two sides of the mail conveying belt 4 and a first horizontal rod 92 crossing the two first vertical rods 91, and the 3D camera 6 is arranged on the lower side of the first horizontal rod 92, and the side surface code scanning camera 7 is arranged on the side of the first vertical rod 91 facing the mail conveying belt 4. The bottom surface code scanning camera 11 is perpendicular to the side surface code scanning camera 7, and the bottom surface code scanning camera 11 faces the mail feeding robot 3. In use, the mail feeding robot 3 flips the mail to make the bottom surface of the mail face the bottom surface code scanning camera 11, and the bottom surface code scanning of the mail is completed through the bottom surface code scanning camera 11. If a bar code is identified on the bottom surface of the mail, the mail is placed on the mail feeding table 2, and the mail feeding table 2 conveys the mail to the mail feeding conveying belt 1. If no bar code is identified, the side surface code scanning of the mail is completed through the side surface code scanning camera 7. In this process, the mail feeding robot 3 rotates the mail to complete the scanning of the four side surfaces of the mail. If a bar code is identified, the mail feeding robot 3 places the mail on the mail feeding table 2, and the mail feeding table 2 conveys the mail to the mail feeding conveying belt 1.

[0023] The side surface code scanning camera 7 has two, which are oppositely arranged on the inner sides of the two first vertical rods 91, so that the two side surface code scanning cameras 7 can simultaneously scan the opposite two side surfaces of the mail. When no bar code is identified by the two side surface code scanning cameras 7, the mail feeding robot 3 only needs to rotate the mail by 90° to complete the scanning of all side surfaces. Compared with the scanning of the four side surfaces of the mail by a single side surface code scanning camera 7, which needs to be rotated by at least 270°, the two opposite side surface code scanning cameras 7 can greatly reduce the horizontal rotation angle and improve the scanning efficiency.

[0024] The lower part of the feeding robot 3 is a chassis 31, a wheel (not shown) is arranged at the lower end of the chassis 31, and the feeding robot 3 can be moved to a position convenient for taking and placing parts through the wheel, improving the flexibility and working efficiency of the robot, and the chassis 31 has an automatic navigation function. A stand 32 is arranged on the chassis 31, which serves as a support structure and provides a reliable mounting platform for subsequent parts. A vertical slide rail 33 is arranged on the stand 32, a sliding block 34 is arranged on the slide rail 33, and a feeding mechanical arm 35 is arranged on the sliding block. The sliding block 34 can freely slide on the slide rail, so as to realize flexible adjustment of the feeding mechanical arm 35 in the vertical direction. The cooperation of the automatic navigation chassis 31 and the slide rail 33 and the sliding block 34 enables the feeding robot to adapt to different feeding spaces, walk and lift, and complete larger range of work tasks. The mechanical arm 35 in the embodiment adopts an RM75 mechanical arm of Ruierman Intelligent Technology Co., Ltd., and other models of 6-axis or 7-axis mechanical arms can be selected according to actual conditions.

[0025] An suction cup 36 is arranged on the feeding mechanical arm 35, which can adsorb the mail by generating negative pressure to realize stable grabbing of the mail. The sliding block 34 and the feeding mechanical arm 35 are both two, symmetrically arranged on both sides of the stand 32, and the two feeding mechanical arms 35 can alternately take and scan the code of the mail. When one feeding mechanical arm 35 sends the mail to the feeding table 2, the other feeding mechanical arm 35 can grab the mail and scan the bottom and four sides, so as to realize seamless connection of the work process. This alternating working mode not only reduces the waiting time, but also greatly improves the sorting efficiency of the mail. The feeding mechanical arm 35 is an intelligent light mechanical arm, which can not only accurately control the action according to the preset program, but also has sufficient load capacity to cope with the taking and placing requirements of the mail. The receiving chute 10 has two, one is arranged below each feeding mechanical arm 35, and the light parts or special-shaped parts that cannot be read by the bar code or cannot be sorted by the machine are placed into the receiving chute 10 by each feeding mechanical arm 35 for manual sorting.

[0026] A rotating table 37 is further arranged between the chassis 31 and the stand 32, so that the feeding mechanical arm 35 can cover a wider taking and scanning area, and can easily cope with mails in different positions without moving the whole robot. Moreover, through the precise control of the rotating table 37, the feeding mechanical arm 35 can more efficiently complete the operations of taking, scanning and placing, and further improve the sorting efficiency.
