[0018] The present invention will be further described below in conjunction with the embodiments.

[0019] The present invention provides a material transportation management method, which can check all parts information in the assembly process according to the assembly process, including the types of parts, production batch numbers of parts, assembly time, assembly workers and other related information. Through the data processing of the host computer, the production rhythm of the pulsating production line and the quality characteristics and traceability of parts in the assembly process can be effectively controlled. It is equivalent to building an "identity card" for the assembled product. At the same time, coupled with the automated logistics transportation of the system, the engine assembly efficiency is significantly improved.

[0020] Material transport management methods, such as Figure 1 The method specifically comprises the following steps: Place the parts to be installed in the profiling tray. The profiling tray is made of soft material to prevent the parts from being damaged during the movement of the profiling tray. The profiling tray is provided with grooves of corresponding shapes for all parts; when placing the parts to be installed on the profiling tray, place the parts to be installed in the corresponding grooves.

[0021] After placement, check the parts to be installed on the contoured tray. The process of checking the parts to be installed is as follows: A six-axis robotic arm drives an industrial camera to perform visual inspection and compare it with the background system data to clarify the number and type of parts to be installed.

[0022] After the inspection is completed, the operator moves the contoured pallet to the installation station through the AGV dispatching system. Each time the operator uses the AGV dispatching system, he or she uses a separately issued password to start the AGV dispatching system.

[0023] The operator transfers the required material brackets from the material warehouse to the installation station through the AGV dispatching system. The AGV dispatching system is equipped with RFID, which identifies the material brackets at different stations. A display is set on the material bracket to display the assembly process; refer to the assembly process to install the parts to be installed.

[0024] The parts to be installed are installed according to the material bracket to form a product.

[0025] After the installation is completed, the product is inspected and the installation completion results are uploaded to the industrial computer. After the installation is completed, the product is visually inspected by an industrial camera; the industrial computer stores the installation completion results.

[0026] After the product is installed, the entire installation process and the information of the parts to be installed are printed out using a QR code printer to generate a certificate. The certificate is affixed to the product to form an identification.

[0027] The improvement of material transfer during engine assembly is relatively simple, and the use requirements can be met through AGV transfer.

[0028] Single trace management and digital system construction are the key to the entire system. The trace management bracket mainly provides technical support for the transportation and management of materials. The industrial camera on the transport platform captures the existence of materials in the material tray, and then the barcode scanner enters the information of the parts to be assembled into the industrial computer of the equipment. The system integrates the part status of the industrial camera and the part information recorded by the barcode scanner to generate a QR code. The QR code is pasted on the assembled parts.

[0029] The present invention mainly solves the problems of high labor intensity in material transportation during engine assembly and the construction of a digital material system. Figure 2 As shown in the figure, all parts information in the assembly process can be checked according to the assembly process, including the type of parts, production batch number of parts, assembly time and assembly workers and other related information. Through the data processing of the host computer, the production rhythm of the pulsating production line and the quality characteristics of the assembly process and the traceability of parts can be effectively controlled. It is equivalent to building an "ID card" for the assembled product. At the same time, coupled with the automated logistics transfer of the system, the efficiency of engine assembly is significantly improved.
