Description

Technical Field

[0001] This utility model relates to the field of reed processing technology, and in particular to a reed pretreatment device for an automatic riveting machine. Background Technology

[0002] In automatic riveting machines, the reed feeding system is a key component for achieving efficient and precise production. Its main functions are as follows: The reed feeding system automatically transports reeds from the storage area to the riveting station through storage, supply, and conveying devices, replacing manual operation. Through sensors or vision systems, the feeding mechanism can precisely control the position and orientation of the reeds, avoiding misalignment or jamming. Automated feeding avoids errors and speed limitations caused by manual intervention, enabling high-speed continuous operation. The reed feeding system can be adapted to different reed specifications through program adjustments or mechanical replacement. A reed pre-processing device is required in the reed feeding system to perform relevant pre-treatment processing on the reeds before feeding.

[0003] Traditional automatic riveting machines have several shortcomings in their reed pretreatment devices. First, they are not suitable for inputting reed strips and cannot achieve precise conveying of the reed strips. Second, they lack bending functionality and cannot perform bending processing on the reeds in the reed strips to adapt to contact assembly. Third, they cannot cut the bent reeds to separate them from the strip.

[0004] In view of this, the inventors aim to design a spring pretreatment device for an automatic riveting machine that can meet the needs of the automatic riveting machine's feeding system for conveying, bending, and cutting spring strips. Summary of the Invention
