Automatic welding equipment capable of improving welding precision

Abstract

The invention discloses automatic welding equipment capable of improving welding precision, and relates to the field of welding automation. The automatic welding equipment capable of improving the welding precision solves the defects that in the prior art, the welding precision requirements of sheet metal in precision devices cannot be ensured. The automatic welding equipment comprises a base, a gantry mechanism disposed on the base and a welding mechanism disposed on the gantry mechanism. The welding mechanism is separately driven by an X-axis traveling assembly, a Y-axis traveling assembly and a Z-axis traveling assembly which move in the X-axis direction, the Y-axis direction, and the Z-axis direction. The welding mechanism comprises a welding gun, an X-axis rotating assembly for driving the welding gun to rotate along the X-axis and a Y-axis rotating assembly for driving the welding gun to rotate along the Y-axis separately. The welding gun is provided with a laser tracking systemand a spectral confocal sensor, and the laser tracking system comprises a laser device and a monitoring lens. By implementing the technical scheme, different sheet metal can be flexibly welded, and the sheet metal in the precision device processing and production process can be accurately welded to ensure the welding precision requirements of the sheet metal in the precision devices.

Description

technical field [0001] The invention relates to the field of welding automation, and more specifically relates to an automatic welding device capable of improving welding precision. Background technique [0002] Straight sealing and circular seams are the most common welding seams in tailor welding of steel plates, which put forward higher requirements not only in terms of welding strength, precision, efficiency, appearance, etc. for sheet metal welding in the process of precision device processing and production. As an important fine processing method, laser welding has the advantages of narrow weld seam, small heat-affected zone, high welding precision, and smooth weld seam. It has been widely used in the welding of various metal sheets, such as welding of minimally invasive medical device components, Welding packaging of small sensor parts, fuel cell metal diaphragm welding packaging, precision welding packaging of special sensor components, and welding packaging of FBG f...
