Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to an automatic terminal assembly machine. Background Technology

[0002] Terminal blocks are essential basic connection components in electrical equipment, power distribution systems, and various electronic circuits. They are mainly used to achieve reliable conduction and connection between cables and electrical components, and between cables themselves. They have the advantages of convenient wiring, flexible disassembly and assembly, and stable conductivity, and are widely used in many fields such as power, industrial control, communications, and home appliances.

[0003] The current assembly and processing of multi-point wiring terminals still generally adopts the traditional manual assembly line operation mode, that is, multiple operators work together to complete multiple processes such as component sorting, alignment, assembly, and pressing in sequence, and finally complete the finished assembly of the wiring terminals.

[0004] This manual assembly line method has many inherent defects in actual production applications: manual assembly has extremely low production efficiency. Due to the small size of the terminal block components, it takes a long time for operators to assemble each one, making it impossible to achieve standardized, continuous, high-speed production and difficult to adapt to the needs of large-scale market production. Manual assembly is prone to omissions. Terminal block assembly involves a large number of components and dense processes. Long-term repetitive manual operation can easily lead to fatigue and lack of concentration, resulting in frequent omissions. In addition, there are problems with poor assembly consistency and large errors, such as component misalignment, inconsistent tightness, and insufficient fit. This leads to inconsistent assembly quality of batch products and difficulty in unifying product precision.
