[0002] Industrial valves are important accessories for controlling the flow of media on industrial pipelines. They can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

[0003] The valve assembly production line refers to an automated production line for valve assembly. The process flow of the valve assembly production line includes the following steps: 1. Valve parts inspection: Check the quality of valve parts to ensure they meet the requirements; 2. Valve assembly: Assemble the valve parts according to the process requirements to form a complete valve; 3. Valve performance test: Perform performance test on the assembled valve to ensure that it meets product requirements; 4. Quality inspection: Check the quality of the assembled valves, including appearance, size, and material. Surface inspection; 5. Packaging: Pack qualified valves for transportation and sales.

[0004] During the valve assembly process, the valve housing needs to be fixed, and then the robotic arm assembles the parts to be assembled with the valve housing. During assembly, the traditional valve assembly production line usually places the valve housing on the conveyor belt surface first. When the conveyor belt transports the valve housing to the specified position, the valve housing is clamped and fixed by the robotic arm. However, the valve housing may shake under the conveyor belt, causing the valve housing to tilt or shift in angle. After the robotic arm clamps and fixes the valve housing, the valve housing cannot maintain the correct assembly position and angle, affecting subsequent assembly work. Summary of the invention
