[0021] The following is a further description of the device of the present invention in conjunction with specific embodiments, which are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the device of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope limited by the claims attached to the application.

[0022] See also Figures 1 to 2The process flow diagram of the present invention, the structural principle diagram of the multi-way valve double half-bridge system simulation model, and the intelligent distribution method of factory standard parts are characterized by comprising the following steps: 1. According to the standard operation book and the use requirements of standard parts of the assembly line, a control system is established, a standard parts warehouse is established and logistics personnel are assigned to be responsible for the standard parts warehouse, and standard parts shelves 7 are set up. Standard parts are replenished according to the labels of the AGV material boxes 2 on the shelves. A shelf button 4 for prompting is set under each AGV material box 2. The shelf button 4 is provided with a three-color light, and a 3D monitoring board is established; 2. A line shelf 8 is set up beside the assembly line, and a material calling button and a three-color light for prompting are set on the line shelf 8; 3. The workers on the assembly line take the corresponding number of standard parts from the AGV material box 2 on the line shelf 8 before installing the parts according to the requirements of the assembly standard operation manual; 4 When the standard parts in the AGV material box 2 are used up, press the material call button below the AGV material box 2 on the line shelf 8 to perform the material call operation; 5 After pressing the button to call for material on the assembly line, the corresponding material position on the line shelf 8 automatically changes to an empty material position. The communication module 6 set on the line shelf 8 transmits the empty material position information to the warehouse management system through the 5G signal. The warehouse management system determines whether the corresponding loading position of the standard parts shelf 7 in the standard parts warehouse is full according to the material calling position; 6. If the judgment result obtained in step 5 is full, the storage location management system will generate a distribution task, which will be passed to the scheduling system. The scheduling system will assign this task to the material box AGV9, and the material box AGV9 will start to run and execute the distribution task; 7. If the judgment result obtained in step 5 is empty material, the logistics personnel in the standard parts warehouse area will wait for the standard parts to be put into AGV material box 2 and press the button of standard parts shelf 7. After binding, the scheduling system will assign this task to material box AGV9, and material box AGV9 will start to run and execute the distribution task; 8 The material box AGV 9 performs the distribution task, carrying the AGV material box 2 containing standard parts, and goes to the line-side shelf 8 that sends the material call signal to feed the material, and at the same time receives the empty AGV material box 2; 9 The material box AGV 9 performs the return task, carrying the empty AGV material box 2, goes to the standard parts shelf 7 that previously took the material, places the empty box to the position where the AGV material box 2 with the standard parts was taken away, and displays a red light; 10. Run the 3D monitoring dashboard to display that the position on this shelf in the standard parts warehouse is empty, reminding the logistics personnel to replenish the materials.

[0023] The three-color light can change colors including red, yellow and green, and the three colors can be switched among each other.

[0024] The control system includes a storage location management system, a dispatching system, and an intelligent charging system.

[0025] A partition is provided inside the AGV material box 2 .

[0026] The 3D monitoring dashboard includes the modeling of the standard parts warehouse, the surrounding environment of the transportation route, and the line-side shelves 8.

[0027] The material box AGV 9 is provided with four backpacks and the number of AGV material boxes 2 transported at one time is three.

[0028] It also includes a dispatching center, which includes computers and displays.

[0029] Through the warehouse management system, scheduling system, intelligent charging system, material box AGV9, 3D monitoring board for monitoring the operation of material box AGV9, shelf button 4, and communication module 6, the standard parts warehouse, production line side warehouse, and line side distribution are integrated into an intelligent distribution line that meets the production and on-time distribution requirements, realizing a mode in which production site demand drives warehouse material distribution, and distribution is realized in batches, intelligently, and on-time, better adapting to the complex and changing industry dynamics of the market, realizing flexible production of the production line, improving production efficiency, and reducing labor costs.

[0030] The standard parts shelf 7 has the same structure as the line-side shelf 8. One shelf can be divided into four layers, and each layer can hold four material boxes. A button is set under each material box, and each button can display a different color. The material loading personnel in the warehouse can quickly load the materials according to the color displayed on the button. After loading the materials, they only need to press the shelf button 4 to quickly bind them. It is convenient, fast, and foolproof.

[0031] Through the dispatching system, the control of the material box AGV9 is realized, including the task assignment of the material box AGV9, the solution of the optimal operation route, the control of vehicles at intersections, the grabbing and placement of the material box AGV9, so as to realize the intelligent and automated distribution of standard parts. Operators in the warehouse area and on the assembly line can judge the operating status of the material box AGV9 according to the color displayed by the shelf button 4. It is simple and clear, with a high degree of intelligence and visualization. After the material box AGV9 is used for distribution, the material boxes on the distribution line are placed more neatly and orderly, and the surface of the material box is labeled to facilitate the operator to quickly find and pick up standard parts, improve the on-site 5S and assembly efficiency.

[0032] A material box is partitioned by partitions, that is, a material box can hold multiple standard parts. Standard parts that are less frequently used are placed in different areas in a material box to improve the utilization rate of the material boxes, reduce the number of material boxes on the line, and achieve lean placement. According to the material call frequency of the material boxes on the assembly line side, the number of material box AGV9 deliveries can be reduced by setting the task collection time, thereby saving costs.

[0033] Working principle: After pressing the shelf button 4 on the assembly line to call for material, the material position at the button on the shelf automatically changes to an empty material position. The communication module 6 on the shelf transmits the empty material position information to the warehouse management system through the 5G signal. The warehouse management system determines whether the corresponding loading position is full according to the material calling position. If it is full, the warehouse management system will generate a delivery task, which will be passed to the scheduling system. The scheduling system will assign this task to the material box AGV9. If it is empty, the logistics personnel in the standard parts warehouse area will put the standard parts into the material box and press the button to bind. The scheduling system will assign this task to the material box AGV9, and the material box AGV9 will start to run and execute the delivery task.

[0034] Intelligent human-computer interaction: The present invention requires that there are shelf buttons 4 under all material boxes, and the shelf buttons 4 are equipped with three-color lights. When the operator at the assembly line presses the button, it shows red, indicating that the logistics personnel in the standard parts warehouse area have not loaded materials. When the button shows yellow, it means that the material box AGV9 is performing a delivery task. When there is no demand for materials, the button shows green, indicating that there is no delivery task and no materials are needed. When the material box AGV9 sends the full material box to the assembly line and puts the corresponding empty material box back to the standard parts warehouse area, the button under the corresponding shelf in the standard parts warehouse area shows a red light, and at the same time, the 3D monitoring board is run to show that this storage location is empty, reminding the operator to replenish materials. The feedback of the button's three-color light perfectly realizes human-computer interaction, and can effectively feedback the operating status of the material box AGV9 to the operator. It is easy to operate and has a high degree of intelligence. When there is no task, all the buttons on the shelf show green, which is highly visible and enhances the corporate image.

[0035] Flexible use of material boxes: This distribution method requires a one-to-one correspondence between the number of unloading shelves on the assembly line and the loading shelves in the standard parts area, as well as the order in which the material boxes are placed on the shelves. This innovative requirement can meet the production needs of different models. For example, material box No. 1 is loaded with M12×25 bolts, which are only used when producing small models. The advantage of this distribution method is that when M20×30 bolts are used to produce large models, the logistics personnel in the standard parts warehouse area can communicate with the operators on the assembly line to directly replace the M12×25 bolts in the material box with M20×30 bolts. This method is simple to operate and highly flexible, meeting the flexible production of multiple varieties, small batches, and customized products under the complex and ever-changing market dynamics.

[0036] Efficient material box transfer: The material box AGV9 has four backpacks. If all four backpacks are filled with material boxes at one time, an extra shelf must be added to the assembly line for empty and full exchange, that is, put down the full material box first and then pull the empty material box. In this way, the line needs to double the number of shelves and buttons, which takes up a lot of space and is costly. The innovation of this delivery method is that it can transfer up to 3 material boxes at a time, occupying three backpacks of the material box AGV9, and the other backpack is used for empty and full exchange. When the material box AGV9 pulls 3 material boxes in the standard parts area and drives to the line to unload When unloading materials, first pull the empty material box from the shelf 8 on the assembly line side and place it on the fourth backpack of the material box AGV9, then place the full material on the shelf 8 on the assembly line side, and so on, to achieve empty and full exchange unloading. In addition, the placement position of the empty material box has a "memory" function, because the material boxes in the standard parts warehouse area and the material boxes on the line side are one-to-one corresponding, so the empty material box pulled by the line side unloading will be placed in the corresponding position in the standard parts warehouse area, so that the standard parts of the same specification and model can be exchanged between the standard parts warehouse area and the assembly line side through the material box AGV9. This innovative empty and full exchange method of material boxes effectively reduces the number of line-side shelves 8 and material boxes, reduces costs, and improves transportation efficiency.

[0037] Centralized replenishment of standard parts: The intelligent distribution method for factory standard parts provided by the present invention can realize the scheduled and fixed-point loading of materials by logistics personnel in the standard parts warehouse area. Materials can be loaded on time according to the rhythm requirements of the assembly production line, which greatly concentrates the working time of logistics personnel. The working area is only concentrated in the standard parts warehouse area, with a small range of activities and high work efficiency.

[0038] Advanced 3D monitoring board for material box AGV9 operation: A factory standard parts intelligent distribution method provided by the present invention can realize 3D monitoring of material box AGV9 operation. By building a 3D model of the entire factory and using it as the background for the operation of the material box AGV9, the material box AGV9 can run in real time in this 3D working scene, picking up materials, releasing materials, going straight, turning, etc. Each action is clearly visible, and the starting point and the end point of material picking are tracked and displayed in real time, with a full sense of technology. The data display on both sides can intuitively see the AGV's operating material rate, order execution analysis, material box AGV9's operating time statistics, failure rate, etc. The operating rhythm of the material box AGV9 can be optimized according to the operating parameters, and the status of the AGV can be monitored. This 3D monitoring board realizes a 3D stereoscopic display in the operating scene, and all AGV actions are clearly visible, which is convenient for operators to view and logistics management, realize digital empowerment, and intelligent manufacturing. It is at the leading level in the industry and has high practicality and visiting value.

[0039] The intelligent distribution method of factory standard parts provided by the present invention relies on the automatic transportation of the material box AGV9. When the material management system receives the material call from the button box on the shelf 8 at the side of the production line, the material management system makes a judgment and generates a corresponding distribution task. When the loading area is bound to standard parts, the material management system transfers the loading point and unloading point tasks to the scheduling system, and the scheduling system assigns the material box AGV9 to perform the distribution task.

[0040] After receiving the task information from the material management system, the dispatching system will assign the material box AGV9 to perform the task based on the task requirements, AGV load, AGV idle status, and whether there is electricity. After the material box AGV9 receives the task, the dispatching system will plan the optimal path for the AGV based on the task requirements, the standard parts collection points in the standard parts area, and the placement points on the shelves of the assembly production line. The corresponding route will be sent to the corresponding AGV, and the operation status of the AGV and the control of vehicles at intersections will be monitored at all times to ensure that the vehicle completes the task quickly.

[0041] After receiving the task and planned route issued by the scheduling system, the material box AGV9 goes to the corresponding position of the standard parts area under the laser SLAM navigation 10 according to the planned route, drives to the side of the shelf by moving forward, backward or turning, and scans the shelf and the material box QR code 3 to pull the target material box. After all the materials are picked up, the material box AGV9 continues to move according to the planned route. When the material box AGV9 moves to the shelf 8 next to the production line with the standard parts, the trolley stops moving and pulls the material box on the shelf to the backpack. After automatically pulling the full material box of standard parts to the shelf, it automatically runs back to the standard parts warehouse area and places the empty material box on the corresponding shelf. At this point, the current task is completed. If no task is issued, the AGV runs to the parking space and waits. If a new task is received, it continues to execute the new task.

[0042] The power of the material box AGV9 is provided by the electric motor. The dispatching system detects the power of the material box AGV9 from time to time and sends the power information to the intelligent charging system. The intelligent charging system automatically controls the charging and power management of the material box AGV9 according to the set charging time period and power safety threshold. When the charging time period is reached, the intelligent charging system sends the charging task to the dispatching system. After receiving it, the dispatching system will determine whether to arrange the material box AGV9 to perform the charging task according to the power status of each material box AGV9. After the intelligent charging system receives the arrival information of the material box AGV9 sent by the photoelectric switch sensor of the charging pile, it controls the charging brush block to extend and complete the automatic charging to ensure that the car has sufficient power during the working time period. When the power of the material box AGV9 is lower than the set safety threshold, the intelligent charging system will immediately send the charging task. After receiving the task, the dispatching system will give priority to arranging AGV to perform the automatic charging task to prevent the car from being too low in power during the non-charging time period due to other reasons, damaging the battery or even causing the car to shut down automatically after power feeding.

[0043] The material box AGV9 runs in real time in the 3D work scene, picking up materials, unloading materials, going straight, turning, etc. Each action is clearly visible, and the starting point of picking up materials and the end point of unloading materials are tracked and displayed in real time. The data display on both sides can intuitively see the AGV's operating material rate, order execution analysis, material box AGV9's operating time statistics, failure rate, etc. According to the operating parameters, the operating rhythm of the material box AGV9 can be optimized and the status of the AGV can be monitored. This 3D monitoring board realizes a 3D stereoscopic display in the operating scene. All AGV actions are clearly visible, which is convenient for operators to view and manage logistics, realize digital empowerment, and intelligent manufacturing. It is at the leading level in the industry and has high practicality and visitability.

[0044] The present invention integrates the standard parts warehouse, the assembly line side shelf 8, and the line side distribution into a lean and intelligent distribution line that meets the production rhythm, realizes the mode of production demand driving the warehouse material distribution, and realizes batch, intelligent, punctual, and automated distribution, better adapts to the complex and changeable industry dynamics of the market, realizes flexible production of the production line, and improves the phenomenon of mixed placement and untimely distribution of standard parts at the production site, realizes the timing and fixed-point loading of logistics personnel, and loads materials on time according to the rhythm requirements of the assembly line, greatly concentrates the working time of logistics personnel, and the working area is only concentrated in the standard parts warehouse area, with a small range of activities and high work efficiency. The material box AGV9 replaces the forklift to carry out material distribution in the workshop, reduces the number of logistics personnel and forklifts, and reduces labor costs. The laser protection and edge contact emergency locking brake designed by the material box AGV9 are more conducive to the safety of personnel in the workshop.
