Description

Technical Field

[0001] The invention relates to the technical field of air conditioner production, and in particular to a copper pipe welding device. Background Art

[0002] There are many copper tubes connecting the two parts of the air conditioner, and various ways of connecting copper tubes are achieved by welding. The current copper tube welding method is generally to connect the two sections of copper tubes through the upper and lower ends of the large and small ends, and use a clamping tool to connect and weld in batches. Copper tube welding must be welded in a vertical welding method. The two sections of copper tubes are placed upright after piping, and the large end of the pipe mouth is at the bottom. During welding, the solder melts and flows into the connection between the large and small ends of the two sections of copper tubes under gravity to fill and complete the welding. If you want to achieve a three-section pipeline welding connection, you must first complete the welding of two sections of the pipeline and then flip it over and pipe it with the third section of the pipeline and place it upright and clamp it for welding. The automatic welding equipment for the three-section copper tube welding process requires two starts and stops, two piping, two loading and unloading, and two inspections. In addition, traditional welding equipment cannot realize automatic inspection after welding (identification of welding defects). It is necessary to manually unload the materials and check and confirm the welding defects of the copper tubes one by one, and the welding production efficiency is low. Summary of the invention
