[0002] Flux can help and promote the welding process in the welding process, and at the same time is a chemical substance with a protective effect and can prevent oxidation reactions.

[0027] Such as Figures 1-4As shown in the figure, an embodiment of the present utility model provides an annular glue scraping mechanism, including: a rotating mechanism, an automatic solder flux adding mechanism, a blade height adjusting mechanism, and a solder flux bucket fixing mechanism.

Further tighten the fastening bolt 15 to fix the lifting table 13 at an appropriate height position, facilitating the glue scraping operation. The blade body 16 is adsorbed to the lifting table 13 through a magnet, and the blade body 16 can be quickly removed before disassembling the disc 21, avoiding obstruction to the removal of the disc 21.

[0036] Finally, input the flux into the rotating shaft 20 through the conduit 6, and extrude the flux in the rotating shaft 20 by opening the injection valve 17, facilitating the application of the flux on the disc 21. Then, by pulling out the injection valve 17 from the support rod 18, the spring 19 bounces upward to push the rotating shaft 20 and the injection valve 17 upward, further rotating the injection valve 17 along the rotating shaft 20 to a position away from the disc 21, facilitating the rotation of the liquid outlet head of the injection valve 17 to a position that does not obstruct the disc 21, facilitating the disassembly of the disc 21.
