Description

Technical Field

[0001] The present invention relates to the technical field of aluminum sleeve door and window processing, and specifically to an automatic welding device and method for seamless aluminum sleeve doors and windows. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extrusion profiles as frames, stiles, and sash materials, which are called aluminum alloy doors and windows for short. Aluminum alloy doors and windows include those with aluminum alloy as the base material of the stressed members and those combined with wood and plastic. With the improvement of modern process standards, the seamless welding method has gradually been adopted in the welding process of aluminum alloy doors and windows. The seamless welding method has higher aesthetics and also solves the problems of water leakage and low strength in traditional assembly welding.

[0003] After a large amount of retrieval, it is found that the prior art: the publication number is CN213053252U, which discloses a seamless welding device for broken bridge aluminum doors and windows, including a bottom plate, a flip plate, and an air filtration module. A left column is arranged on the left side of the upper end of the bottom plate, and a right column is arranged on the right side of the upper end of the bottom plate. Rotating shafts are arranged at the left end and the right end of the flip plate, and the flip plate is rotationally connected to the left column and the right column through the rotating shafts. The right end of the rotating shaft penetrates through the right column and is connected with a driven bevel gear. A flip power module is arranged at the lower side inside the right column. First through grooves are arranged on the upper side and the lower side of the front end of the flip plate, and first limiting rods are arranged at the upper side and the lower side of the rear end of the flip plate and located at the first through grooves. The materials of this device can be fixed and clamped quickly and conveniently, and it is applicable to a wide range of door and window sizes and models. It eliminates the need for manual laborious handling, facilitates loading and unloading, has better safety, can realize translational welding in the front-back and left-right directions, has a more comprehensive welding angle, can avoid air pollution from damaging the body, collects waste materials to avoid environmental pollution, and is convenient and fast to move.

[0004] To sum up, during the welding process of existing aluminum alloy doors and windows, since the surfaces of the components of aluminum alloy doors and windows are not all flat shapes and there are staggered layers on the surfaces, it poses a great challenge to the seamless welding process. Most traditional seamless welding processes can only weld at flat positions, and the welding of vertical joints at the staggered edges is often not comprehensive enough, thus reducing the welding firmness of aluminum alloy components.
