A manufacturing process of a filament clip wick of an LED filament lamp is: upper core post→guide wire shaping→guide wire flattening→guide wire hook→guide wire correction→upper filament→filament clipping→detection→lower wick classification. The number of repetitions of the processes of attaching the filament and clipping the filament is the same as the number of LED filaments of the clipping wick, and the above-mentioned guide wire is the abbreviation of the electrode guide wire and the series guide wire.
