During the production peak period, material supply delay phenomenon frequently occurs, which causes the equipment to be shut down for a long time to wait for materials, seriously hindering the improvement of overall production efficiency.

[0005] Operation accuracy problem: manual operation is prone to material mistakes, such as missing and missing. Once the wrong material is put into the production link, it will not only cause product quality defects, but also cause waste of raw materials, thereby greatly increasing production cost.

[0006] Management traceability problem: manual distribution lacks systematic management framework and traceability mechanism, and cannot realize real-time and accurate monitoring and recording of the whole process of material flow, which seriously restricts the optimization of production process and quality control work.

[0108] Embodiment 2

[0109] The embodiment also provides an AGV material distribution method for semiconductor packaging and testing, based on the AGV material distribution device for semiconductor packaging and testing described above, including the following processes:

[0110] Material reservation: the DB process operator enters the required glue, suction nozzle, glue pipe, thimble, dispensing head, frame, and other material types, quantities, target equipment numbers, and other key information in detail and accurately on the professional operation interface of the MTMS system according to the daily production plan. For example, the operator plans to carry out chip mounting work on a DB device, and calculates that 1 piece of special type glue, 1 suction nozzle, 1 glue pipe, 1 thimble, 1 dispensing head, and 50 frames are needed. After the input is completed, the MTMS system automatically starts the format check and reasonableness verification program, confirms that the information is correct, and quickly sends the reservation information to the AGV scheduling system to generate a corresponding distribution task.

[0111] Task allocation and vehicle driving: After receiving the material reservation information, the AGV scheduling system will comprehensively consider the real-time position, load state and task execution progress of each AGV in the current workshop, and accurately match the most suitable AGV for the distribution task. Assuming that the AGV-003 is in an idle state and is close to the material room at this time, the scheduling system will assign this distribution task to AGV-003. After AGV-003 receives the task information through the wireless communication antenna assembly (2-7), the navigation algorithm carried inside AGV-003 quickly plans the optimal driving path from the current position to the material room according to the pre-set map and workshop layout information. Then, the AGV driving chassis (1) starts, and the vehicle strictly follows the planned path.

[0112] Material loading: After AGV-003 successfully arrives at the material room, the MTMS system sends instructions to the vehicle through wireless communication, and the electric control board 2-18 receives the instructions and quickly controls the electronic lock 2-13 to open the corresponding storage compartment. The material room administrator accurately finds the corresponding material according to the detailed prompts on the PDA of the MTMS system. For example, the administrator first takes out a bottle of glue, scans the two-dimensional code on the glue package using the PDA, and after the PDA reads the material information, scans the identification code of the glue compartment 4-4 in the small material storage compartment, accurately binds the glue information with the glue compartment, and puts the glue into the glue compartment. According to the same standard process, the suction nozzle, glue pipe, needle, dispensing head, frame and other materials are placed in the corresponding storage compartment, the door is closed, and the electronic lock automatically completes the locking operation. At the same time, the material room administrator feeds back the information of material loading completion to the MTMS system in a timely manner through the PDA.

[0113] After AGV-003 confirms that all storage compartment doors have been closed and locked securely, it drives to the target DB device according to the established planned path.

[0114] Material delivery: When AGV-003 accurately arrives at the target DB device, the operator scans the device number using the PDA, and the wireless communication antenna assembly 2-7 of AGV-003 receives the scanning information and quickly transmits it to the electric control board (2-18). The electric control board accurately matches and verifies the received device number with the pre-stored task information, and after successful verification, controls the electronic lock 2-13 to open the corresponding storage compartment. The operator takes the required material from the storage compartment and confirms the receipt on the PDA. AGV-003 feeds back the material delivery information to the MTMS system in a timely manner through wireless communication, and the MTMS system updates the material inventory information and task status, and records that the material has been successfully delivered to the target device. At this time, AGV-003 returns to the material room according to the instructions of the MTMS system to wait for the next task, or goes to the charging area for charging, fully preparing for the subsequent distribution task.

[0115] According to the above, from the DB operator inputting material reservation information on the MTMS system, it shows how the information is passed to the AGV scheduling system, to the AGV receiving the task, planning the path to the material room, driving to the target equipment after loading the material, and finally completing the whole process of material delivery, as shown in Figure 6 The information interaction and operation process between each link are clear and coherent, which helps to fully understand the logic and operation mechanism of the material distribution method. Production managers can monitor and optimize the entire material distribution process through the diagram, timely find bottlenecks and problems in the process, and take appropriate measures to improve the efficiency and accuracy of distribution.

[0116] In this embodiment, the mechanical connection between the AGV drive chassis 1 and the material bearing platform assembly 2 uses high-strength bolts to fasten, and a torque wrench is used during the fastening process to ensure that the fastening force of each bolt meets the design requirements. In terms of electrical connection, all cables use shielded cables and are strictly planned for wiring to avoid cable crossing and winding. After the connection is completed, professional electrical test equipment is used to comprehensively test the conductivity and insulation of the electrical connection to ensure the safety and reliability of the electrical system. After the wireless communication antenna assembly 2-7 is installed, signal strength and signal stability tests are performed in different positions and different environments to ensure good communication with the MTMS system and the AGV scheduling system. During the mechanical connection process, the fastening force of each bolt is recorded for subsequent inspection and maintenance. When wiring, draw detailed wiring diagrams to provide a basis for later maintenance. When testing the wireless communication antenna assembly, simulate the complex electromagnetic environment of the semiconductor packaging workshop to ensure communication quality.

[0117] When the electronic lock 2-13 is integrated with the MTMS system, multiple rounds of communication protocol compatibility testing are performed to ensure that both sides can accurately identify and respond to instructions. In the MTMS system, multiple test scenarios are set, such as normal door opening, abnormal door opening, permission verification, etc., to test and optimize the response time of the electronic lock, lock state feedback, etc. The material information display screen assembly 2-5 and the MTMS system perform data interaction debugging to ensure that the display screen can display real-time and accurate material information, task progress, etc. sent by the MTMS system, and optimize the format and refresh frequency of the display content. In the communication protocol compatibility test, multiple communication protocol versions are used for testing to ensure the compatibility of the electronic lock and the MTMS system. User experience testing is performed on the display content of the material information display screen assembly, and the display format and refresh frequency are optimized according to feedback.

[0118] Whole function test: In the driving test, simulate the complex path of the semiconductor production workshop, including right-angle turning, U-turn, narrow channel driving, etc., test the stability, accuracy and speed control performance of the trolley driving. Obstacle avoidance test sets various types of obstacles, such as static device models and dynamic mobile robots, to test the sensitivity and reliability of the trolley obstacle avoidance function. Material storage compartment opening and closing test is carried out at least 1000 times, to test the durability of the hatch and the stability of the electronic lock. Material binding and delivery process test simulates the whole process of material distribution in actual production, from material reservation to delivery completion, tests the coordination and data accuracy of each link, and optimizes and improves the problems found in the test. In the driving test, record the driving parameters of the trolley under different paths, and analyze its stability and accuracy. In the obstacle avoidance test, count the number of successful obstacle avoidance and failure cases, and optimize the obstacle avoidance algorithm accordingly. Analyze the test results of the material storage compartment opening and closing, and improve the design of the easily worn parts.

[0119] In the material reservation link of this embodiment: In the production workshop of the semiconductor packaging and testing factory, the DB process operator checks the materials required for the production task according to the detailed production plan for the day. For example, if chip mounting is planned on a DB device, it is calculated that 1 tube of glue, 1 suction nozzle, 1 glue pipe, 1 needle, 1 dispensing head and 50 frames are needed. The operator enters information such as material type, quantity, target device number, etc. in the MTMS system operation interface. After the input is completed, the MTMS system automatically compares the materials. After confirming that there is no error, the system sends the reservation information to the AGV scheduling system, generates a corresponding distribution task in the AGV scheduling system, and assigns a unique task number to the task.

[0120] Task allocation and trolley driving link: After receiving the material reservation information, the AGV scheduling system matches the most suitable AGV trolley for the distribution task. Assuming that the trolley numbered AGV-003 is in an idle state at this time, and its current position is close to the material room, after algorithm evaluation, the scheduling system assigns this distribution task to AGV-003. After the vehicle-mounted control system of AGV-003 receives the task information through the wireless communication antenna assembly 2-7, it quickly plans the optimal driving path from the current position to the material room according to the pre-stored workshop map information in the vehicle-mounted control system and the real-time acquired position information of AGV-003. Subsequently, the AGV drive chassis (1) starts, and the trolley drives according to the planned path. In the driving process, the laser radar installed at the front and side of the trolley is always in working state, constantly scanning the surrounding environment to ensure safe and timely arrival at the material room.

[0121] Material loading link: After AGV-003 arrives at the material room stably, the MTMS system sends instructions to the trolley through the wireless communication network. After the trolley's electrical control board 2-18 receives the instructions, it controls the electronic lock 2-13 to open the corresponding storage cabin. The material room administrator holds a PDA device and quickly locates the required material storage area according to the detailed prompts pushed by the MTMS system on the PDA. For example, when taking glue, the administrator accurately takes one corresponding type of glue from the shelf, scans the two-dimensional code on the glue package with the PDA, reads the material information, and transmits it to the MTMS system for verification. After verification, the administrator scans the identification code of the glue cabin 4-4, the MTMS system binds the glue information with the glue cabin, and records the binding time, operator, and other detailed information in the system. The administrator puts the glue into the glue cabin, closes the cabin door, and the electronic lock automatically completes the locking action. For suction nozzles, glue pipes, needles, glue heads, and frames, etc. materials, they are all operated according to this standard process. After completing the material loading, the material room administrator feeds back the loading completion information to the MTMS system through the PDA, and the MTMS system updates the material loading status in real time, and simultaneously deducts the material inventory in real time.

[0122] Material distribution link: After AGV-003 confirms that all storage cabin doors have been closed and locked firmly, it drives to the target DB device according to the planned path.

[0123] Material delivery link: When AGV-003 arrives at the target DB device, the operator next to the device scans the device number with a PDA device. After the wireless communication antenna assembly 2-7 of AGV-003 receives the scanning information, it quickly transmits it to the electrical control board 2-18. The electrical control board accurately matches and verifies the received device number with the pre-stored task information, and after successful verification, it controls the electronic lock 2-13 to open the corresponding storage cabin. The operator takes the required material from the storage cabin and confirms the receipt on the PDA. AGV-003 feeds back the material delivery information to the MTMS system in time through wireless communication, and the MTMS system updates the material inventory information and task status, and records that the material has been successfully delivered to the target device. At this time, AGV-003 returns to the material room according to the instructions of the MTMS system to wait for the next task, or goes to the charging area to charge, fully preparing for the subsequent distribution task.

[0124] To sum up, the application provides an AGV material distribution method for semiconductor packaging, which automatically receives the distribution task of the mobilization system through the electric control operation platform and starts the AGV driving chassis, reduces manual intervention, improves the response speed and execution efficiency of the distribution task. The material two-dimensional code and the identification code of the material storage area are bound to ensure that the material can be accurately placed in the corresponding storage space, avoid errors that may occur during manual placement, and improve the accuracy of distribution. After the material is placed, the electronic device locks each storage space to prevent illegal access or removal of the material during the distribution process, enhancing the security of the material. The binding of the material two-dimensional code and the identification code not only helps accurate placement, but also facilitates subsequent material tracking and management, ensuring the safety and traceability of the material during the entire distribution process.
