Research notes
This is a pneumatic tufting gun designed as the end-effector of a tufting robot, from a large Shandong carpet group. It is close kin to the Hofmann/Scholz pneumatic hand gun and Wilcom's pneumatic head. A companion utility model, CN212426405U ("pneumatic multifunctional carpet pricking gun for an intelligent robot"), appears in the same similar-documents lists, but I did not see its date. Another background citation, CN108642747A (an intelligent robot gun-tufting device with screw-driven XYZ motion, cited in CN110468525A), was seen only secondhand. Verified Oct 2026 by web search only. patents.google.com and Espacenet could not be opened from the sandbox, so I did not read the document itself. The dates and assignee come from a citation row on the ATE522650T1 Google Patents page. The English title comes from another Google Patents page. Research note (Oct 2026): found through search results; the patent document itself wasn't opened. The Patent drawings job fetches the document from Google Patents; if drawings appear on this record, the number is confirmed.
