Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1-5 , in the embodiment of the present utility model, a friction stir welding aluminum chip collection device includes: a collection mechanism 200 for cleaning and collecting aluminum chips. The collection mechanism 200 includes: a vacuum generator 210, the input end of the vacuum generator 210 is connected and fixed with a material extraction and feeding cover 220, and the output end of the vacuum generator 210 is connected and fixed with a PVC pipe 230. A storage component is arranged at the top of the PVC pipe 230, and a positioning component is arranged outside the vacuum generator 210; an air blowing mechanism 300 for blowing off aluminum chips.

[0033] Specifically, by fixing both the collection mechanism 200 and the air blowing mechanism 300 on the welding head 110, after the friction stir welding equipment 100 is used up, the collection mechanism 200 is used to suck and store the aluminum chips milled by the flash milling tool 120, and the air blowing mechanism 300 is used to blow off the aluminum chips milled by the flash milling tool 120, facilitating the collection mechanism 200 to suck the aluminum chips, making the use more convenient.
