A handheld laser welding gun

Abstract

The invention provides a handheld laser swinging welding gun. A collimation unit, a light path unit and a control unit are included. The collimation unit is provided with a collimation lens and a collimation connection barrel for fixing the collimation lens. The two ends of the collimation connection barrel are oppositely provided with a laser incident end and a laser emitting end. The light pathunit is used for adjusting the direction of laser emitting from the collimation unit, light spots are formed, and laser emitting can be adjusted. The light path unit comprises a light path body and aswinging body. The light path emitting end of the light path body is upwards bent and is connected with a welding head, and the light path incident end of the light path body is connected with the laser emitting end of the collimation unit. The swinging body upwards extends in the direction deviating from the outer end face of the light path incident end of the light path body. The control unit isused for controlling welding head laser emitting. The handheld laser swinging welding gun has the advantages that the light spots can be adjusted to be output, the handheld laser swinging welding guncan adapt to different sizes of welding lines, various complex technologies are met, the structure is compact, the dead load is small, light losses are few, and the welding efficiency is high.

Description

Technical field[0001]The invention relates to the technical field of laser welding, in particular to a handheld laser welding gun.Background technique[0002]As an advanced welding technology, laser welding is now commonly used in electronics, automobiles and other industries in conjunction with automated control systems. At present, there are mainly three types of manual hand-held welding in the market: argon arc welding, manual welding and ordinary laser welding. Among them, argon arc welding and manual welding have higher requirements for operators and are prone to safety problems. The general application of handheld laser is relatively small, and it is not easy to operate, and it is easy to weld through the product; secondly, the spot size of the welding head (welding gun) used in the existing handheld laser welding is not adjustable and cannot be well adapted to different Weld size requirements.Summary of the invention[0003]The object of the present invention is to provide a hand...
