Description

Technical Field

[0001] The present invention relates to the technical field of laser welding, and in particular to a single-sided irradiation integrated laser welding device and a laser welding method. Background Art

[0002] Laser welding is a high-precision welding technology, and its process mainly includes pretreatment, alignment, welding and post-processing. First, pretreatment is carried out, that is, the objects to be welded are cleaned and dirt is removed. Then alignment is carried out to accurately position the objects to be welded to the required position. Next is the welding process, which irradiates the laser beam on the objects to be welded to melt them locally, and then connects the two objects together.

[0003] Chinese patent CN118321721A discloses a laser welding device and method for steel cord, which relates to the relevant field of steel cord welding. A laser welding device and method for steel cord include a frame, a laser welding head and an industrial camera, and also include: a horizontal platform fixedly connected to the frame, with an adsorption boss integrally formed at the bottom for negative pressure adsorption positioning rubber sleeve; a flipping platform that can be flipped on the frame, and is located directly below the horizontal platform after flipping upward to horizontal; an elastic pressing member that is elastically slidably arranged on the horizontal platform in the vertical direction; a driving wheel group, including two first pulleys that are symmetrically connected to the flipping platform and can rotate synchronously in opposite directions; a pressing wheel group, including two second pulleys that are symmetrically connected to the bottom of the elastic pressing member; two first half tubes for initially limiting the steel cord, which are symmetrically fixed on the flipping platform; two second half tubes for initially limiting the steel cord, which are symmetrically fixed on the horizontal platform.

[0004] In order to ensure the precise docking of the two sets of welded parts during welding, auxiliary tools are needed to help the welded pipes to dock. It is troublesome to manually connect the welded pipes with the auxiliary tools. In the above document, the positioning rubber sleeve is adsorbed by the negative pressure of the adsorption boss, and the automatic blanking of the steel cord and the positioning rubber sleeve is completed by releasing the adsorption after welding. However, after the flip platform rotates to horizontal, the first half of the pipe on the flip platform docks with the second half of the pipe above. At this time, the friction between the first half of the pipe, the second half of the pipe and the welded workpiece will hinder the first pulley and the second pulley from driving the movement of the welded workpiece, resulting in greater resistance to the welded workpiece during movement and docking.
