The utility model discloses a light bar gluing device for
LED lamp tube production, which belongs to the technical field of light bar gluing and comprises a
processing table, a clamping component is arranged at the top of the
processing table, a fixing support is slidably connected to the top of the
processing table through a moving module, and a gluing body is fixedly connected to the bottom of the fixing support. According to the leakage-proof device, the leakage-proof
assembly is arranged, the transmission gears drive the other transmission gears to rotate through the rotating gear ring, the transmission gears drive the sliding columns to move downwards through the lifting lead screws, the sliding columns drive the attaching wheels to move through the triangular plates, and the attaching wheels drive the sealing plates to move through the sliding rods; the multiple sealing plates are arranged on the gluing
pipe, so that the multiple sealing plates are attached to each other and seal the glue outlet of the gluing
pipe, on one hand, the glue outlet can be blocked in time, the situation that glue drips and influences the gluing effect is avoided, on the other hand, the gluing
pipe is in a sealed state through attachment of the multiple sealing plates, glue in the gluing pipe can be effectively prevented from being oxidized and hardened, and the service life of the glue is prolonged.
