Further, according to the goal and principle of the project construction integration verified by the engine digital assembly, with reference to the related experience of the same company, and according to the current and future requirements of the workshop for the digital platform and the intelligent manufacturing, the functional framework of the system constructed by the project is summarized as shown in fig. 3, and the field control layer, the access layer and the object layer are mainly constructed.

The functional framework mentioned above is explained in detail below with reference to fig. 3. Fig. 3 is a schematic frame diagram of an assembly verification project overall function block according to an embodiment of the present invention.

As an example, the specific functional blocks in fig. 3 are described as follows:

(1) An object layer: the object layer defines the elements embodied throughout the assembly process, embodied in object form, including equipment, materials, personnel ABOM, and other objects. The properties of each class of objects are also specified.

(6) A display layer: the display carrier comprises a workshop production information large screen and a field billboard.

Furthermore, in order to ensure the security of the system, the enterprise office network, the server local area network and the workshop local area network are maintained independently, especially the workshop local area network, so that more data are collected and data are interacted frequently, and the workshop local area network and the office network must be separated in order to ensure the stability of the network. As shown in fig. 4.

The above-mentioned network architecture is explained in detail below with reference to fig. 4. Fig. 4 is a schematic diagram of a network architecture topology according to an embodiment of the present invention.

A workshop local area network: and a ring network is adopted, and redundancy configuration is adopted. The system accesses the ring network through one node to collect data.

System server local area network: the data volume involved is large, so isolation protection is needed between the server local area network and the office network.

The whole system operates in a closed mode, but the system is divided into two parts from the aspect of network architecture: production operation and manufacturing execution, wherein a production management and control part is deployed in a network (based on a PC system and secret-involved), and mainly undertakes butt joint with a production order of an MES system, planning and scheduling and the like; and the manufacturing execution is deployed in an industrial control network (based on a PLC system and secret), is responsible for seamless fusion with relevant equipment of a digital production line, plays a role of an information physical fusion system, and realizes intelligent control on the operation of the whole production line.

Furthermore, the operation efficiency is higher through integration among the systems. Generally speaking, system integration only emphasizes data interaction among partial information systems in most cases, and ensures that key production information can be circulated and shared in each business system. For an engine production line, the aim is to realize real digital manufacturing, and the fusion of service flow and data flow among systems must be communicated until intelligent manufacturing is realized, so that closed-loop control is realized; more importantly, the integration of all process equipment (as shown in fig. 5) ensures that production runs according to a set beat, improves the efficiency of the equipment and reduces the stock pressure.

The above-mentioned system integration is explained in detail below with reference to fig. 5. Fig. 5 is a schematic diagram of an overall integrated framework between intelligent assembly sample boards.

ERP and MES system integration: the MES system needs to integrate data and applications with systems such as production planning and scheduling, material management systems and the like in the ERP system. Through the interface, the ERP system can issue production orders, process parameters, material main data and the like to the MES system of the workshop, otherwise, the MES system feeds back actual production information to the ERP system, such as material consumption data, production quality data and the like, so that seamless integration and data butt joint between heterogeneous systems are realized.

2. PLM integration with MES systems: the integration solution of PLM and MES is a seamless approach, not only can improve the production flexibility, but also can improve the production speed, provide innovative products and optimized methods, and can ensure the overall visibility transfer requirement in the production and engineering fields by distributing the latest product design and assembly methods to more, faster and more efficient production value chains.

The business relationship between the PLM and the MES is not just a simple synchronization of data, but also includes interoperability of business logic. Tight system integration, such as between TeamCenter and SIMATIC IT, can be achieved between the PLM and the MES. The data synchronization of the two is realized not by an intermediate file mode in the traditional sense but by bottom-layer function intermodulation, the efficiency and the integrity of data transmission are considered in the whole process, and enterprises are guaranteed to be established on the basis of a unified data source. TeamCenter and SIMATIC IT implement a tight coupling between design systems and manufacturing execution systems through unique internal data channels. The synchronous data content is not only literal, static and local, but also comprises a complete data packet of global data such as structural parameters, production guidance files, three-dimensional digital models and the like, so that the consistency of various main data information such as product numbers, material codes, tool codes, personnel numbers and the like in two systems and the matching degree of hundreds are ensured.

The PLM transmits the complete product data packet to the MES through an internal channel, and each module inside the MES is respectively responsible for receiving and storing different types of product design data.

3. The ERP system and the MES system are integrated with the WMS: and the ERP system and the MES system are integrated with the WMS system in the level through a database communication mode. And synchronizing the material information in real time by using the intermediate view.

4. MES and AMS system integration: the MES system communicates with the AMS system in a database intermediate table mode, the MES system issues production work order information to the AMS system, and the AMS system arranges production by combining field conditions according to the work orders. And the AMS system simultaneously feeds back the execution condition of the work order to the MES system.

5. AMS and simulation system integration: the AMS system communicates with the simulation system in a database intermediate view mode, and transmits real-time assembly information to the simulation system.

6. The SCADA system communicates with the AMS system: the SCADA system and the AMS system communicate in a database intermediate table mode, the AMS system sends production line scheduling information to the SCADA system in a main table, and the SCADA system scans the scheduling information from the AMS system in real time. And the state and real-time data of each system and equipment controlled at the current place are returned to the AMS system in the SCADA system sub-table. As the basis for sensing the status of the working conditions in the field.

7. Communication between the SCADA system and the field system and equipment: the SCADA system communicates with field systems and equipment by using an industrial bus and other high-speed industrial communication protocols, and sends action information to the field systems and equipment. Meanwhile, real-time operation data are fed back to the AMS system by the on-site system and the on-site equipment.

The SCADA system and the AMS jointly form the core of a digital production line. The production scheduling instruction of the AMS system is issued to the SCADA system, the SCADA system conducts real-time and dynamic command on the production line, meanwhile, the running state and abnormal information of the production line are synchronously sent to the AMS system in near real time, the AMS system is sent to the central control part of the AMS system to conduct real-time decision and command, and after the execution is completed, the information is fed back to the upstream informatization system.

Further, through analysis, the assembly process of the invention enables the small engine to have the process characteristics of compact structure, small volume, light weight, medium process flow length and small and medium batch in batches, a fixed assembly mode of one person for one machine is suitable for small production, a pulse assembly method is suitable for being adopted after the batch exceeds a certain value, a pulse assembly mode of one person for one machine or one person for one machine can be adopted for the engine with shorter process flow, and a pulse assembly mode of one person for one machine can be adopted for the engine with longer process flow.

The above-mentioned assembly process is explained in detail below with reference to fig. 6. Fig. 6 is a flow chart of an assembly process according to an embodiment of the present invention.

The main form of the assembly production of the domestic traditional engine is as follows: one person one machine one position fixed assembly production line: one person is responsible for all technological processes of assembling one engine, one person is responsible for one station, and people and engines are not moved.

The main forms of the existing domestic and foreign digital engine assembly production line comprise: "one person one machine" pulsating assembly line: one person is responsible for all process flows of engine assembly, but the person and the engine are circulated among multiple stations, and an AGV trolley is adopted in a circulation mode, so that the method is suitable for small-batch assembly of small and medium-sized simple engines; "one person one position" pulsating assembly line: a plurality of persons are responsible for assembling one engine, each person is responsible for part of the process flow, one person is responsible for one station, the persons do not move, the engines are circulated among the stations, the circulation mode can adopt an AGV trolley, a truss moving system or a transmission system, and the method is suitable for large-scale assembly of large-scale complex engines.

At present, the digital processing production line at home and abroad mainly comprises the following forms: the assembly line of "one-piece multi-machine": a part is processed in a circulation mode among a plurality of machine tools, each machine tool is responsible for part of the process flow, a machine arm or a movable frame system is adopted in the circulation mode, the method is suitable for variable-batch processing, and automation can be achieved in the whole process, so that unmanned factories can be achieved.

The invention simultaneously analyzes the existing various production lines, considers that the engine is uneconomical to realize full automatic assembly, but can realize cost-optimal production through the effective combination of logistics automation, partial operation automation and human-computer interaction. Aiming at the characteristics of small size and light weight of a small engine, an AGV trolley or a robot arm can be adopted in a circulation mode, but the requirement of assembling and overturning the engine is considered, the functions of station circulation and engine overturning can be realized through the robot arm, and the using number of the robot arm can be determined according to the number of stations.

As the invention verifies that the engines have more types, the process flow is short and complex, the disassembly and rework are caused by various problems in the assembly process, the production quantity is single, small and medium-sized in batches, and the production time is centralized, interval and flow production. Aiming at the complex production condition, any mature production line mode cannot completely meet the flexible requirement of engine assembly, so that a production line scheme suitable for the engine assembly needs to be designed by combining the advantages of the existing production line.

Based on the analysis and the specific assembling process flow of the engine, the invention designs the overall layout of the assembling production line. The floor space of the verification project is about 24m multiplied by 7.1m. And conveying the assembled products between the stations from the core machine assembling station to the final performance detection station by utilizing an industrial robot. The logistics are conveyed in a mode of an AGV material transfer trolley.

In order to better realize the establishment of future intelligent storage of a factory, an AGV delivery mode is adopted in a logistics system, the AGV trolley can be used as a logistics conveying carrier to improve accuracy, meanwhile, the workload of workers can be reduced, the maximum load of the AGV trolley is 200kg, the AGV trolley can move in all directions conveniently through differential wheels, in order to guarantee personnel safety, an area scanner is respectively arranged in front of and behind the AGV trolley, the scanning angle is 120 degrees, the maximum sensing distance is 3 meters, and the response time is less than 0.2 second. The assembly process flow diagram of the verification project is shown in fig. 6.

The design is this workshop mainly be considered improve product quality uniformity, improve that the process is controllable, improve convenient operation nature and reduce the operation degree of difficulty. The whole production line is managed by an AMS (automatic management system) and a regional assembly electrical control system, and is integrated with a device PLC (programmable logic controller) system through an industrial Ethernet, so that the assembly process of the device is monitored, and the process controllability is realized.

The main assembly line adopts the form of FMS (Flexible manufacturing System), and the main characteristic of the main assembly line is to support Flexible switching of different production capacities. The main assembly line adopts five stations to be in a U-shaped layout, realizes the operation of products among the stations through an industrial robot, and realizes the assembly mode of fixed process content, fixed process equipment and tools, fixed operation sequence and fixed manipulation at each station. Compared with the traditional bench assembly, the production mode has the greatest advantage that the consistency of products can be ensured, and because the assembly processes of all products are consistent in the mode, the randomness of the process and the operation method of each operator in bench assembly is avoided; compared with the pulsating line, the FMS form has greater flexibility in production capacity and relatively lower production line investment. The FMS production mode is very suitable for the production working conditions of small product batch, large fluctuation and complex product. Under the condition of space operation, the FMS assembly line with the U-shaped layout can realize gradual capacity expansion from single station production until all stations are operated simultaneously, the FMS is transited to pulse production, and the capacity flexibility is very high.

In the partial installation district, adopt servo pressure equipment machine, through control pressure equipment power and pressure equipment displacement, can guarantee the position uniformity of bearing assembly, can prevent the quality problems that cooperation size is super poor simultaneously. The quality of the assembly can be improved.

On-site operators operate according to the AMS system terminal prompt and the operation guidance formed after the step-level data packet is disassembled, so that the stability of the production process is effectively improved. Meanwhile, data acquisition and recording of a step-level physical environment are realized.
