Description

Technical Field

[0001] The utility model belongs to the technical field of assembly lines and relates to a continuous DC charging pile production line with a buffer function. Background Art

[0002] At present, in the industry, the production of DC charging pile products still mainly relies on the production line because of the large number of structural parts and complicated assembly. This processing method has high processing efficiency and high scalability, and can achieve efficient processing effects of different types of DC charging pile products according to different processing requirements; however, compared with other product structures, DC charging pile products still have certain technical problems when using assembly line processing;

[0003] In the process of assembly line processing, due to certain differences between the previous and subsequent processing steps, the processing time required between the processing steps will also be different. In some processing stations that require a longer time, product accumulation is inevitable. Due to the large overall structure of the DC charging pile, it is not easy to remove it from the product line for temporary storage. This requires the entire assembly line to be temporarily shut down, resulting in a reduction in overall processing efficiency and failure to meet the needs of efficient processing.
