Research notes
This is another 2020 robot gun-tufting head, part of the same burst of filings as CN111705448A. 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 number, English title and dates come from a similar-documents row on a Google Patents page, as summarised in a search result. A direct search for the Chinese title found nothing. 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.
