Description

Technical Field

[0001] This utility model belongs to the field of capacitor manufacturing technology, and in particular relates to a nail needle detection device for an aluminum electrolytic capacitor nailing machine. Background Technology

[0002] During the manufacturing process of aluminum electrolytic capacitors, the riveting machine often encounters problems such as the riveting needle colliding with foreign objects or the aluminum rod of the guide pin, resulting in broken needle tips. This leads to poor riveting effect and high contact resistance. Consequently, the capacitors may experience issues such as no capacitance or overheating and arcing at the riveting point during use. If this phenomenon is discovered during production, the entire batch of products must be scrapped, resulting in significant waste. To address this problem, a needle detection device needs to be designed to monitor the riveting force each time. When a needle tip breaks, the riveting force changes. When the detected force exceeds a set range, the equipment stops and alarms to prompt an inspection of the needle condition, reducing the possibility of defective products being mixed with good products.
