[0004] In addition, hot riveting is generally used for automobile plastic part welding, and the welding head of hot riveting is usually made of copper material, and sometimes iron fluoride plating layer is added to the surface, so that the welding head and the product can be separated more easily after welding. During welding, the welding head is first heated to working temperature, and then the welding head is pressed to the welding rib of the plastic part by servo motor or air cylinder, the high-temperature welding head melts the welding rib of the plastic part, and after welding, high-pressure gas is released to the position of the welding head to make the melted plastic in the welding head solidify again. Finally, the welding head is lifted to complete the welding. However, in order to reduce the cost, the welding time is usually forcibly shortened, and the biggest problem of shortening the welding time is that the temperature of the welding head after being blown by gas has not risen to the working temperature, and the next round of welding work is performed, which causes the product to appear virtual welding problem.
