Automatic shearing equipment for LED flexible lamp filament

The invention discloses an LED flexible lamp filament automatic shearing device, and relates to the field of LED flexible lamp filament shearing. The automatic shearing device for the LED flexible lamp filament comprises a base, a propelling mechanism, a pre-loading mechanism, a shearing mechanism and a sensing mechanism. The base is arranged on the ground as a substrate and is responsible for bearing other mechanisms; the pushing mechanism is installed on the base and is responsible for controlling the position of the lamp filament in real time and cooperating with the shearing mechanism to shear the lamp filament. The pre-loading mechanism is mounted at the front end of the propelling mechanism and is responsible for loading the next batch of filaments in advance, so that the filling time is shortened; the shearing mechanism is mounted at the foremost end of the propelling mechanism and is responsible for shearing the lamp filament; and the sensing mechanism is mounted at the rear end of the shearing mechan
