Description

Technical Field

[0001] The utility model relates to the technical field of bonding wire production, in particular to a wire-breaking prevention pulling device for bonding wire drawing equipment. Background Art

[0002] The wire breakage prevention device plays a crucial role in bond wire drawing equipment. The following are its main functions: 1) Traction and Guidance: The core function of the wire breakage prevention device is to pull and guide the bond wire, ensuring stable and continuous movement during the drawing process. This precise pulling prevents wire breakage or damage caused by uneven force or deviation during the drawing process. 2) Wire Breakage Protection: The device is designed with a wire breakage prevention mechanism. When it detects abnormal wire tension or the risk of breakage, it takes immediate action, such as stopping or adjusting the pulling speed, to protect the wire from damage. This protection mechanism is crucial for ensuring production continuity and product quality. 3) Improved Production Efficiency: The wire breakage prevention device enables precise control of the bond wire drawing speed, working in conjunction with other drawing equipment components to form an efficient production line. This helps improve production efficiency and reduce waste and downtime. 4) High Adaptability: The wire breakage prevention device is typically designed with adjustable pulling force and speed to accommodate the drawing needs of bond wires of different specifications and materials. This adaptability enables the device to be widely used in various bonding wire production equipment.

[0003] Traditional wire-breaking prevention pulling devices used in bonding wire pulling equipment have shortcomings. First, they cannot adjust the pulling position according to the position of the thick bonding wire on the unwinding reel, resulting in less than ideal wire-breaking prevention pulling effect. Second, they cannot adjust the direction according to needs, resulting in high pulling resistance. Therefore, it is necessary to optimize and improve traditional wire-breaking prevention pulling devices used in bonding wire pulling equipment. Utility Model Content
