Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to an integrated full-automatic cooling medium and protective gas joint. Background Art

[0002] Laser welding uses high-energy laser pulses to locally heat a small area of ​​the material. The energy of the laser radiation diffuses into the interior of the material through heat conduction, melting the material to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts. Handheld laser welding machines are emerging laser welding equipment in recent years. They are simple to operate, easy to use, flexible and convenient, and can weld longer distances. They overcome the limitations of the workbench space and are used when automatic welding is not possible when the workpiece sizes are not uniform.

[0003] After searching, the application with patent number 202122275392.0 discloses a handheld laser welding head, including a main body, a handle located on one side of the main body, and a cover plate located on the top of the main body, wherein the main body includes a fixing frame arranged in the middle position of one side of the main body, and a fixing plate is arranged on the side of the fixing frame away from the main body. The utility model controls and adjusts system parameters through a secondary card display screen and a scroll button. The relevant parameters adjusted on the main display screen can also be displayed simultaneously on the secondary card display screen, so that the parameters of the gun head secondary card display screen are synchronized with the parameters of the cabinet main display screen, and the adjustment of the secondary card display screen parameters with the scroll button will also be recognized and executed synchronously by the main display screen, that is, the power, frequency, red light width, wire feeder wire feeding and wire retracting speed and other parameters can be adjusted on the gun head by toggling the scroll button, and a three-color indicator light is also installed next to the secondary card display screen, and different colors represent different status indications;

[0004] The above application document adjusts the welding parameters by scrolling buttons, but uses a traditional welding head to assist the work. The safety of direct laser welding with a traditional welding head needs to be improved, and the cooling effect of the laser cutting method is poor, which affects the welding efficiency.

[0005] Therefore, we propose an integrated fully automatic connector for cooling medium and shielding gas. Utility Model Content
