Description

Technical Field

[0001] The present application relates to the technical field of terminal block assembly, and in particular to a terminal feeding structure for fully automatic plugging of terminal blocks. Background Art

[0002] Terminal block, also known as Terminal Block, is an electrical device used to connect and distribute power or signals, and is widely used in power systems, automation control systems, instrumentation systems, communication networks, etc. Its main function is to provide a safe, reliable and reusable connection interface to facilitate electrical connection between devices.

[0003] In the related art, the structural design of the terminal block mainly includes a base and the wiring terminals arranged thereon. In order to realize the efficient assembly of the wiring terminals, an automatic feeding system, such as a robotic arm, is usually used to accurately transport the wiring terminals from the storage area to the predetermined assembly position and place them steadily on the base.

[0004] However, in order to meet the demand for storing a large number of terminal blocks, existing storage areas often occupy a large space. Although the large space provides sufficient storage capacity, it may also lead to low space utilization and a large amount of ineffectively utilized space. This not only increases the overall size and cost of the equipment, but may also cause inconvenience in transportation, installation, and future maintenance and management, and there is room for improvement.
