Auxiliary positioning device facilitating luminous character manufacturing

The utility model relates to an auxiliary positioning device convenient for luminous character manufacturing, which comprises a placing frame, a placing plate is fixedly connected in an inner cavity of the placing frame, a mounting block is fixedly connected to the left side of the placing frame, an L-shaped mounting plate is fixedly connected to the top side of the mounting block, and an acrylic character shell can be supported and positioned. In the machining process, a worker does not hold the acrylic shell with hands, the situation that the work efficiency is reduced due to shaking is effectively avoided, it can be guaranteed that the light-emitting characters rotate on the containing frame, and meanwhile the situation that the light-emitting characters fall off and shake in the rotating process is avoided; a worker does not need to repeatedly move around the luminous character when attaching the sideband, so that the bottom end of a third bolt abuts against and is fixed to the top side of a panel of the
