The utility model discloses a quantitative conveying
inert gas charging device for indicating
neon lamp
processing, which comprises a charging box, a quantitative gas conveying component fixed on the charging box is used for charging and
processing a
neon lamp, a
neon lamp placing structure slidably connected on the charging box is used for supporting and fixing the
neon lamp, and the quantitative gas conveying component comprises a support plate. A fixing frame is fixedly connected to the supporting plate and telescopically adjusts the position of a
piston rod through a telescopic structure, a
piston fixed to the
piston rod penetrates through the quantitative
pipe, and the quantitative
pipe is communicated with the pressurized
inert gas
storage tank through the gas conveying
pipe. According to the
inert gas charging device for indicating
neon lamp processing and capable of achieving quantitative conveying, the quantitative gas conveying
assembly is arranged, a PLC conducts calculation according to
inert gas needed by neon lamps of different types, a piston on a
piston rod is driven to move under the auxiliary effect of a
hydraulic cylinder on a fixing frame, and therefore the needed
inert gas amount is pumped into a quantitative pipe; quantitative
inert gas in the later period enters the
neon lamp through the gas inlet.
