Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioner production equipment, and particularly relates to a heat preservation cotton and copper pipe assembly production line. BACKGROUND

[0002] The copper pipe is one of important parts of the air conditioner and is widely used in the condenser, evaporator and pipe for conveying refrigerant of the air conditioner. In order to ensure the refrigeration or heating effect of the air conditioner, the heat preservation cotton is generally sleeved on the periphery of the copper pipe to reduce the heat exchange between the copper pipe and the outside.

[0003] In the current air conditioner production process, the heat preservation cotton is generally designed as a hollow cylindrical structure matched with the shape of the copper pipe. In the assembly process of the heat preservation cotton and the copper pipe, the copper pipe is generally inserted into the heat preservation cotton by hand. Since the length of the copper pipe and the heat preservation cotton is relatively long, it is difficult for the operator to insert the copper pipe into the heat preservation cotton, and a large amount of time is consumed. In addition, after the inserting process is completed, the operator needs to transport the heat preservation cotton and the copper pipe to the coiling mechanism for coiling operation. After the coiling process is completed, the operator needs to transport the heat preservation cotton and the copper pipe to the packaging station for packaging and then for delivery. As can be seen from the above process, most of the assembly processes of the heat preservation cotton and the copper pipe are completed by hand, which greatly reduces the production efficiency.

[0004] Therefore, finding a technical solution capable of solving the above technical problems has become an important subject for the researchers in the field. SUMMARY
