[0002] In modern industrial and commercial environments, procurement and material management are one of the core links of enterprise operations. The traditional procurement process usually involves a lot of manual operations, including demand submission, supplier selection, order generation, material receipt and payment processing. The complexity and diversity of these links can easily lead to problems such as inefficiency, frequent errors and slow response. In addition, with the expansion of enterprise scale and the increase in logistics needs, relying solely on manual management of material handling and warehousing can no longer meet the requirements of efficient operations.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By integrating the procurement information management system, the whole process from demand submission to payment processing is automated, reducing manual operation and intervention, and improving procurement efficiency and accuracy. The system's database module stores and manages all relevant data, including material information, order information and handling records, so that each link of the procurement process is highly transparent and traceable, which is convenient for reviewing and optimizing procurement strategies. The handling robot automatically performs material identification, path planning, handling and placement tasks, which significantly improves the efficiency of warehousing and logistics links and reduces material processing time. The maintenance robot can automatically detect and repair the handling robot when it fails, quickly restore the normal operation of the equipment, and reduce downtime caused by equipment failure. Through automation and intelligent means, the system reduces dependence on manual labor and reduces labor costs.

[0014] 2. A self-test signal is sent to the main control module through an external network terminal. The preset program in the main control module sends a self-test working signal to the internal electrical components of the handling robot for self-test operation. When a fault is found, it is determined that the faulty component is the main control module, the drive chassis or the load-bearing chassis. The replacement part is placed inside the right clamping module, and the right clamping module clamps and fixes it. The control module controls the mounting frame and the drive module to start. The mounting frame extends itself to lift the outer shell upward to a specified height. The height of the outer shell is suitable for the handling robot. The drive module drives the maintenance robot to move to the outside of the faulty part of the handling robot. When there is no fault, the drive chassis moves to pull the load-bearing chassis. The sub-control module controls the lifting module to lift and lower the materials.

[0015] 3. Drive the connecting shaft to move through the lifting electric push rod, and then drive the connecting frame to rotate on the outside of the fixed seat with the cooperation of the limit slot. The connecting frame drives the clamping pad to move upward in the inner cavity of the slot hole to disengage and contact the clamping pad, and the load-bearing chassis is released from the driving chassis. The left horizontal driving module drives the lower lifting module to drive the clamping module to move to the fault position. The left lifting module drives the clamping module to descend to the outside of the faulty component. After the clamping module clamps and fixes the faulty component, the left horizontal driving module drives the faulty component to move to the outside with the cooperation of the lower lifting module and the clamping module. The right horizontal driving module drives the lower lifting module to drive the clamping module and the replacement component inside the clamping module to move to the designated position inside the handling robot for replacement, so that the lifting electric push rod is shortened to connect the load-bearing chassis and the driving chassis.

[0016] To sum up, the artificial intelligence robot of the present invention adopts a modular design, so that the components of the robot can be independently repaired and replaced, reducing maintenance costs and time, and uses remote technology for replacement repairs, reducing on-site repair time and improving production efficiency. The present invention integrates procurement information management, database management, automated handling robots and maintenance robots, as well as a network terminal control center. Through this integrated platform, each link in the procurement process can achieve seamless connection and efficient collaboration, thereby optimizing the company's operational efficiency.
