[0040] The material picking system is connected to the mold cloud system. When the connecting piece is inserted into the connecting hole, the material picking system is connected to the mold cloud system. At this time, the material picking system starts to work. The system automatically classifies according to the BOM attribute information. After classification, the electric telescopic rod 6 performs telescopic work. When the electric telescopic rod 6 contracts, the electrode blank 19 falls from the discharge chute into the fixed plate 22 and is blocked by the blocking block 20. When the electric telescopic rod 6 is pushed, the electrode blank 19 is pushed from the fixed plate 22 into the slide 9 and finally into the truck 14.

By equipping multiple groups of material picking systems to load electrode blanks 19 of different materials, and the material is automatically separated for unloading through the final processing of the system, when the operator goes to pick up the material, the conveying device can be taken away. At this time, the connecting piece is disconnected from the connecting hole to terminate the material picking system.

[0041] In Example 1, the method for automatically creating an assembly import system information classification based on industrial software is implemented by using UGNX or PRO-E to perform the following steps:

[0042] S1: Configure the corresponding components of the layer and assign BOM attribute information, including part name, part number, processing method, processing material, hardness, actual specifications and stock specifications. NX automatically creates an assembly component and assigns BOM attribute information to the part, such as part name, part number, processing method, processing material, hardness, actual specifications and stock specifications. The stock specifications are automatically calculated based on the size increment and shape (round or square) assigned by the layer configuration.

[0043] S2: Based on the placement of the corresponding part layers designed by the designer, the component creation tool is used to automatically create assembly components based on the layer configuration and assign corresponding attribute information to the parts, and automatically generate the BOM table based on the assembly component BOM information automatically created by NX;

[0044] S3: Submit BOM information for automatic classification to trigger subsequent business processes. After the BOM attribute information is designed, submit the BOM attribute information to the MoCloud system. The backend automatically generates JT and JPG files and uploads the corresponding PRT files to the system. The system automatically classifies and triggers the procurement, warehouse material collection, ordering and process processing based on the BOM attribute information.

[0045] The material picking system is used in conjunction with the mold cloud system to push the bucket 14 along the fixed rod 13 and into the bottom of the slide 9. At this time, the connecting piece is inserted into the connecting hole. When the connecting piece is inserted into the connecting hole, the material picking system is connected to the mold cloud system. At this time, the warehouse material picking work can be started. Since the types and quantities of materials to be picked are different, they are distributed through the system. The system controls the electric telescopic rod 6 to work. When the electric telescopic rod 6 contracts, the sliding plate 7 leaves the discharge chute. At this time, the electrode blank 19 falls from the storage bin 1 along the discharge chute onto the fixed plate 22. At this time, the electrode blank 19 is blocked by the blocking block 20. When the electric telescopic rod 6 is extended, the electrode blank 19 is pushed from the fixed plate 22 into the slide 9 through the pushing plate 8. The deceleration bag 21 provided on the slide 9 is filled with liquid, so when the electrode blank 19 rolls along the slide 9, the electrode blank 19 will be pressed on the deceleration bag 21, thereby performing a The blocking liquid structure will block the rolling speed of the electrode blank 19 and fall slowly. Even the electrode blank 19 with too fast a speed will be blocked by the baffle 12. Finally, the motor blank falls into the truck 14. The extrusion plate 3 inside the storage bin 1 squeezes the remaining electrode blank 19 after the electrode blank 19 falls onto the fixed plate 22. The electrode blank 19 cannot fall onto the fixed plate 22 due to the blocking of the sliding plate 7. Only when the electric telescopic rod 6 is extended and retracted, the electrode blank 19 will fall onto the fixed plate 22. The operator only needs to retreat the truck 14 to connect the terminal material receiving system with the mold cloud system. The electric telescopic rod 6 is electrically connected to the electric control box. When the connector is inserted into the connecting hole, the power supply of the electric control box is connected to the connector. The connector connects the power supply to the electric control box. Therefore, when the connector is inserted into the connecting hole, the electric control box is connected to the mold cloud system, and the mold cloud system controls the electric telescopic rod 6 through the electric control box to work.

Although the present invention is specifically demonstrated and introduced in conjunction with the preferred embodiments, there are many methods and approaches to implement the technical solution. The above is only a preferred embodiment of the present invention.
