[0033] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention proposes a laser tube base welding device, including a welding melting unit 1, wherein the welding melting unit 1 includes a first support frame 11, a first connecting frame 12, a molten material bin 13, a heating device 14, a connecting line 15, a feed port 16, a feed shaft 17, a protective shaft sleeve 18, a circular ring discharge port 19 and an inner shaft 110.

[0034] In the embodiment of the present invention, an inner shaft 110 is provided inside the feed shaft 17, a circular ring discharge port 19 is provided between the inner shaft 110 and the feed shaft 17, a protective shaft sleeve 18 is provided at the lower part of the feed shaft 17, and the outer diameter of the inner shaft 110 is consistent with the size of the shaft diameter hole 35, so the inner shaft 110 can be inserted into the shaft diameter hole 35, and the circular ring discharge port 19 is consistent with the shape and size of the welding ring 36. When the inner shaft 110 is inserted into the shaft diameter hole 35, the circular ring discharge port 19 is It is located directly above the welding ring 36. A protective shaft sleeve 18 is provided at the lower part of the feed shaft 17. The inner diameter of the protective shaft sleeve 18 is consistent with the outermost shaft diameter of the welding ring 36, so the protective shaft sleeve 18 can completely insert the upper part of the fixed base 34 therein. When the circular ring discharge port 19 places the melted adhesive strip 27 on the surface of the welding ring 36, the protective shaft sleeve 18 can prevent the melted adhesive strip 27 from leaking out, and the protective shaft sleeve 18 can limit the movement of the melted adhesive strip 27.

After the processing is completed, the lower conveyor belt 33 conveys the processed fixed base 34 to the bottom of the controller 45, so as to complete the welding of the fixed base 34 and the laser pipe 47.
