A material pushing seat groove is provided on the material pushing seat 77. The material pushing seat groove is used to place the box cover. After the box cover is placed in the material pushing groove, its upper half is exposed, which is convenient for the clamping cylinder to take. When the material pushing seat 77 is pushed out from the bottom of the well-type silo, the box cover on the material pushing seat is pushed out together, and then the box cover is pushed to the position of the material taking platform 71, which is convenient for the subsequent taking work of the transfer mechanism.

[0043] like Figure 1 and Figure 8 As shown, the double-well feeding unit 7 is conducive to the storage and dispersion of box covers of different materials, and is further conducive to the demonstration and training of the automated control process of the double-well feeding. The action process of the double-well feeding unit is controlled by the industrial control console, and the control program of the double-well feeding unit can be written, entered, and updated at the location of the industrial control console, which is convenient for the automated practical training and teaching.

[0047] like Figure 1 and Fig. 9 As shown, when a metal part passes on the belt conveyor 81, the first inductive proximity switch 84 will give a feedback signal, and only when metal passes, the first inductive proximity switch 84 will have a signal change reaction. After the first inductive proximity switch 84 detects that a metal box cover passes on the belt conveyor 81, the first push cylinder 82 pushes the metal box cover to the first receiving rack 83. The non-metal box cover will continue to be conveyed by the belt conveyor 81 to the bottom of the first photoelectric proximity switch 87. After the first photoelectric switch detects the box cover, the second push cylinder 85 pushes the box cover to the second receiving rack 86.

[0048] like Figure 1 , Figure 8 , Fig. 9 As shown, the present invention can realize the practical training demonstration of discharging, transferring and sorting the box cover by the cooperation between the industrial control table 2, the double-well feeding unit 7 and the conveying and sorting unit 8. At the same time, the industrial control table 2 is used for the automatic electric control of the double-well feeding unit 7 and the conveying and sorting unit 8, and is also used for programming, program writing or updating of the action process program of the feeding unit 7 and the conveying and sorting unit 8, and further for the practical training demonstration of the automatic work.

[0049] like Figure 1 and Fig.10As shown, the image acquisition and weighing unit 9 and the assembly unit 10 include a tray 91, a top plate 92, an industrial camera 93 and a fill light 94. The tray 91 is arranged on the top plate 92, and a guide rod 95 is fixedly connected to the tray 91. The top plate 92 is provided with a hole for inserting and slidingly connecting the guide rod 95. The guide rod 95 passes through the top plate 92 downward. A sensor frame 96 is provided on the upper side of the bottom plate, and a weighing sensor 97 is provided on the sensor frame 96. The lower end of the guide rod 95 abuts against the weighing sensor 97. A certain gap is provided between the bottom of the tray 91 and the upper side of the top plate 92. Light racks are provided on the left and right sides of the support frame 61, and each light rack is provided with a fill light 94.

[0052] like Figure 1 , Figure 6 and Fig.10 As shown, by combining the assembly unit 10 and the industrial robot unit 3, the training work of snap-fit ​​assembly of the box cover and the box bottom can be realized. The action process of the training work is: the industrial robot 3 replaces the manipulator with the first gripper manipulator 53 at the automatic hand change unit 5 → the industrial robot 3 places the box bottom on the assembly seat 103 → the industrial robot unit 3 replaces the manipulator with the negative pressure suction cup manipulator 51 at the automatic hand change unit → the industrial robot unit picks up a box cover and places it above the box bottom → the assembly seat moves to the protective box 101 → the pressing head presses the box cover to complete the snap-fit ​​operation → after the assembly is completed, the assembly seat moves out of the protective box → the industrial robot unit 3 replaces the manipulator with the second gripper manipulator → the industrial robot unit transfers the assembled workpiece. During the training work, the industrial control console 2 is used for the control, program entry, writing, and updating of the industrial robot unit 3 and the assembly unit 10. This facilitates the complete training work. A finished product material warehouse is provided on the training workbench 1, and the finished product material warehouse is used to carry the processed finished products.
