Description

Technical Field

[0001] The utility model relates to the technical field of terminal processing, in particular to a terminal strip welding mechanism. Background Art

[0002] A terminal strip (Terminal Strip or Lead Frame) is a common material in the electronics and electrical industries. It consists of a series of preformed metal terminals, which are usually used to connect wires, circuit boards, and other electronic components. The terminal strip is designed in a continuous strip form to facilitate the automated production and assembly processes.

[0003] In the automated production line of electronic manufacturing, welding the head and tail of the terminal strip is to ensure the continuity and stability of the material, thereby improving production efficiency and reducing waste. The key to this process step is to form a continuous strip loop through welding, avoiding production interruptions caused by replacing the disconnected strip. This not only maintains the smooth operation of the production line, reduces non-productive downtime, but also reduces dependence on manual labor, improves the automation level and production efficiency. At the same time, using the tail material instead of discarding it helps to make full use of the material, avoids resource waste, and realizes cost control. In short, welding the head and tail of the terminal strip is an important means to improve the automated production efficiency and resource utilization rate in electronic manufacturing.

[0004] In the existing incoming terminal reels, there will be strips that need to be joined in the middle. The main reason is that during the incoming material production, cutting is required due to quality or process problems. Therefore, during production, one or more gaps appear in the whole reel of the strip, which need to be manually joined. However, manual joining is prone to problems such as difficulty in ensuring the joining quality. At the same time, the efficiency of manual joining is also low. Poor joining quality will lead to a series of situations that affect subsequent processing, such as inaccurate positioning and unsmooth feeding. For this reason, a terminal strip welding mechanism is proposed to solve the above technical problems. Summary of the Utility Model
