Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, and in particular to an ultrasonic welding bushing nut assembly equipment. Background Technology

[0002] Bushing nuts (also known as insert nuts or press-fit nuts) are fastening components widely used in the automotive, electronics, home appliance, and aerospace industries. They are typically fixed to plastic or metal substrates through press-fitting, welding, or bonding. Their core functions include: providing a high-strength threaded connection point for easy subsequent assembly of bolts or screws; enhancing the mechanical properties of plastic parts; and preventing cracking or stripping caused by direct screwing. With the increasing prevalence of lightweight, high-strength materials (such as engineering plastics and composite materials), the limitations of traditional mechanical press-fitting or adhesive bonding processes are becoming increasingly apparent.

[0003] However, in the existing technology, the bushing and clips need to be installed manually. But the speed of manual operation is limited and it is difficult to meet the high-speed cycle requirements of modern production lines, which will result in low installation efficiency.
