The invention discloses a nut insert hot melting workstation, which comprises a workbench arranged in the workstation; a positioning clamp assembly is arranged on the workbench; an automatic feeding assembly is arranged on one side of the workbench; a plurality of robots are arranged on the other two sides of the workbench, and material taking assemblies are arranged at free ends of the robots; and the material taking assembly clamps inserts on the automatic feeding assembly and moves the inserts to the position above the positioning clamp assembly to be subjected to hot melting operation. Thenut insert hot melting workstation provided by the invention can automatically conduct nut insert welding work, the automation degree, the intelligent degree and the flexibility are good, all movingparts can move independently or cooperatively, and no movement interference is generated between the moving parts; by adopting an automatic control technology, the welding operation becomes easy and simple, the welding efficiency is high, and the quality is better; and the whole layout is simple and compact, the occupied area is small, no pollution or waste exists in the welding process, noise islow, and the working environment is simple and environmentally friendly.
