Abstract

The invention relates to an automobile seat map pocket braid and a puncture welding process thereof, and the process comprises the following steps: checking a braid and a map pocket plastic body to be welded, and ensuring cleanness and flatness; a water pipe is arranged on the side face of the welding position for refrigeration; a puncture welding head is close to the braid at the speed of 0.1 m / s, and when the distance between the puncture welding head and the braid is 3 mm, welding is conducted at the speed of 0.01 m / s; the welding holding time is longer than or equal to 2.5 s; detecting the puncture welding strength of the braid, wherein the braid is required to meet the requirement that the drawstring stripping force is greater than or equal to 30N after being welded with the map strip plastic body; the map bag braid is welded through high-frequency vibration ultrasonic puncture equipment, the advantage that welding spots are firm, smooth and attractive is achieved, a special pressing tool is applied, a map bag body and the braid are pressed flatly, cooling and rapid forming of the puncture spots are guaranteed through refrigeration of water pipes on the two sides, and the purpose of being attractive in appearance is achieved.
