Description

Technical Field

[0001] The present invention relates to the technical field of evaporator assembly, in particular to an air-conditioning evaporator assembly system and an assembly process thereof. Background Art

[0002] The air conditioner evaporator is a type of evaporator. The function of the air conditioner evaporator is to use the liquid low-temperature refrigerant to evaporate easily under low pressure, turning into steam and absorbing the heat of the cooled medium to achieve the purpose of cooling.

[0003] The air conditioner evaporator is composed of multiple layers of fins, which are output from the punching machine and loosely accumulated. In order to facilitate the subsequent retrieval, a steel needle needs to be inserted into the middle of the fin. The assembly of existing air conditioner evaporators still requires a lot of manual assembly, which is very labor-intensive. For example, the operation of inserting the steel needle into the fin is done manually in the current process, and the inserted fin is transported to the next process. For example, the fin group formed by the fins with the steel needle is transported to the destacking equipment by a robot, and the end plates on both sides are installed manually. For example, the copper tube is inserted into the fin group, which is also mostly manually inserted. Many processes use manual assembly, which is slow and inefficient. Summary of the Invention
