Problems solved by technology

The connection of multiple workpieces is generally achieved through adapters. Due to the differences between workpieces, it is difficult for traditional mechanical positioning to assemble all workpieces and adapters on the same plane to ensure the consistency of laser welding focal length; second, Adapter welding of multiple workpieces involves the positioning of multiple welding positions; in addition, due to the high instantaneous temperature of laser welding, especially when the power is high, this involves the impact of welding temperature on the performance of the workpiece itself.

Abstract

The invention provides a full-automatic laser welder comprising a laser head, a laser head servo mechanism, a feeding and discharging device, a pressing mechanism and a transmission mechanism. The pressing mechanism comprises a plurality of pressing blocks and a pressing block support, wherein each pressing block is provided with a passage for laser emitted by the laser head to pass; and the pressing block support is elastically connected with each pressing block. The transmission mechanism is connected to the pressing block support to drive the pressing block support to move vertically so as to press or separate from corresponding connecting pieces. The laser head servo mechanism can further comprise two portal frames which are bilaterally and symmetrically arranged relative to the feeding and discharging mechanism along the X-direction, and each portable frame is provided with reinforcing ribs. The transmission mechanism can comprise a pair of transmission components which is bilaterally and symmetrically arranged relative to the feeding and discharging mechanism. The full-automatic laser welder can further comprise a gas cooling mechanism, a welding positioning unit and a controller. Therefore, pressing effects of welding spots of workpieces at different heights are guaranteed, welding temperature is lowered effectively, stability of a welding process is guaranteed, and welding optimal rate and efficiency are quite high.

Description

technical field [0001] The invention relates to a laser welding machine, in particular to a fully automatic laser welding machine. Background technique [0002] Due to the advantages of high welding strength, high fatigue resistance, fast welding speed and wide range of weldable materials, laser welding has been widely used in the current welding field. In the connection of multiple workpieces, old processes such as riveting and spot welding have unreliable defects such as connection strength and fatigue strength, and laser welding technology has begun to enter this field. The connection of multiple workpieces is generally achieved through adapters. Due to the differences between workpieces, it is difficult for traditional mechanical positioning to assemble all workpieces and adapters on the same plane to ensure the consistency of laser welding focal length; second, Adapter welding of multiple workpieces involves the positioning of multiple welding positions; in addition, d...
