Composite curtain wall intelligent glue injection unit with double glue injection functions

The invention discloses an intelligent curtain wall glue injection unit with a composite double glue injection function. The intelligent curtain wall glue injection unit comprises a three-axis truss, a structural glue injection machine, a sealant injection machine and a multi-axis robot provided with a glue injection unit. The three-axis truss comprises a supporting stand column, an X-axis truss, a Y-axis truss and a Z-axis truss. The X-axis truss is arranged on the supporting stand column. The Y-axis truss is movably connected to the X-axis truss, and the Z-axis truss is movably connected to the Y-axis truss; the multi-axis robot is movably mounted at the bottom of the Z-axis truss; the glue injection unit is installed at the tail end of the multi-axis robot and comprises a first glue nozzle connected with a structural glue injection machine and a second glue nozzle connected with a sealant injection machine, and an included angle is formed between the extending direction of the first glue nozzle and the ext
