Technical Field

[0001] The utility model relates to the technical field of logistics vehicle production, in particular to a point-net welding device for logistics vehicle production. Background Art

[0002] Logistics vehicles are unit mobile container equipment equipped with four casters for transporting and storing materials. They are often used for logistics distribution in large supermarkets or logistics turnover between factory processes. my country's urban logistics vehicles are showing a rapid development momentum. From January to September 2012, the cumulative sales of urban logistics vehicles reached 10,012 units, a year-on-year increase of 30.9%. The reason is that the quality of my country's urban logistics vehicles is constantly improving, with comfort, fuel economy, expanded space, and more models. They have a stylish appearance like light passenger cars, and at the same time have the space for loading and the ability to transport goods like trucks. They fully meet the needs of urban logistics, greatly increasing consumers' choices and thus increasing their sales.

[0003] A welding device is required for the production of point networks in logistics vehicles, but the existing welding device is only equipped with one welding gun, and multiple welding operations are required to complete the welding requirements. This will result in low welding efficiency and needs to be improved. Utility Model Content
