Chapter 5 Disassembly and Assembly of XAG Agricultural Drone

Overview

The content of this chapter is mainly about the key components disassembly of 2023 P100Pro and V50Pro Agricultural Drone and their related mission system. Some of the content applies to 2022 P100 and V50 Agricultural Drone and their related mission systems. In this chapter, the disassembly process will be presented in graphical process combined with the corresponding serial number. Most of the installation process is the direction of the disassembly process. However, the installation sequence of some structures is different from the disassembly sequence. At the same time, before disassembling the structure and related electronic components, ensure that the power supply cables, communication cables, and pipelines have been separated, and cut off power supply in any form.

Disassembly Requirements

Before disassembly, the damage of the equipment should be inspected, and the maintenance plan should be brought forward. The electronic parts should be tested by testing software or fixture. Test software and fixtures should be used in strict accordance with the Module Test Manual and replace after confirming failure or abnormal function. The structural parts should be replaced according to the "Structural Damage Isolation Manual" after verifying the damage, confirming the composite replacement standard or confirming that the damage will cause a safety risk to the equipment.

Disassembly and Assembly Environment

The disassembly and assembly process must ensure that the room is well lit, and the maintenance process should be carried out by placing the Drone in the designated maintenance area and maintenance platform. Disassembled small parts should be placed in containers such as storage boxes. Electrical equipment should be stored away from water sources and should not be placed at will. Sharp and vulnerable parts shall be placed after being wrapped or protected with foam after removal.

Disassembly Preparation

After the Drone or related mission system has been verified and the maintenance plan has been formulated, the surface of the Drone or related mission system that needs to be disassembled shall be cleaned before disassembly. The relevant parts contacted with pesticides or fertilizers should be cleaned and disassembled after the basic cleaning is completed and air dried.

Disassembly and Assembly Tool List

Disassembly tools are necessary tools in the disassembly of Drone, including hand tools, power tools, calibration tools, auxiliary tools and consumables. The tool has certain risks in use. Therefore, you must strictly follow the Tool Usage Guide when using the tool to avoid personal or property loss caused by wrong operations.

Disassembly and Assembly Procedures

Requirements of General Disassembly and Assembly Procedures

• Screws can be easily removed.

• The structure has no serious deformation and damage.

• Fine engagement between components.

Handling Instructions for Abnormal Disassembly

If disassembly process indicates abnormality, analyze and inspect the abnormal point and use proper tool to disassembly and assembly. Use clean water to remove the dirt if there is dirt during the disassembly. Screw corrosion should be infiltrated with screw loosening agent before removal. Hand tools is preferrable when removing corroded screws to avoid excessive torque of power tools and damage to the screw cup head.

Assembly and Installation Rules

Before assembling, ensure the replacement parts are intact. Assembly and installation should be carried out in a well-lit environment. Before installation, read "Disassembly and Assembly Quality Measurement and Control Point”, understand the correspond model and tighten the screws with specified torque according to the regulations. In installation, if screws need to be fastened, use the screws with corresponding accessories specifications. Check with a torque wrench after installation. Use a red or white marker to mark the anti-slip after verifying that the required torque has been met.
