Description

Technical Field

[0001] The utility model belongs to the technical field of automobile body welding and relates to a hot-melt welding device for an automobile body. Background Art

[0002] Fusion welding involves subjecting the weld joint to a molten state under high temperatures. Because the workpieces are tightly pressed together, the molten metal from the two workpieces mixes under the influence of temperature and gravity, without any pressure. Once the temperature drops, the molten metal solidifies, firmly joining the two workpieces.

[0003] During the welding process of the car body, it is necessary to weld both sides of the roof cover. Generally, laser welding is performed by clamping the laser welding gun with two multi-degree-of-freedom manipulators. The welds on both sides of the roof cover are generally symmetrically arranged. Although two multi-degree-of-freedom manipulators are used for welding, the welding accuracy is high, but the equipment cost is also high, which is not conducive to reducing production costs.

[0004] Based on this, we designed a hot melt welding device for automobile bodies. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems in the existing technology and propose a hot-melt welding device for automobile body.
