The invention discloses an adjusting-type automatic potting machine for LED modules. The adjusting-type automatic potting machine comprises a framework. The framework is fixedly installed on the ground. Glue barrels are fixedly installed inside the framework. A boss is arranged at one side of the upper surface of the framework. A movable potting mechanical arm is fixedly installed on the boss. A fixed platform adjusting device is arranged at the center of the upper surface of a cabinet body. The fixed platform adjusting device is composed of adjusting guide rails fixedly installed at the left end and the right end of the framework, a conveying device located at the center of the framework, an adjusting platform located at the other side of the framework and a fixed device located above the framework together. The fixed device is provided with a stopping detection device. The framework is provided with a controller. The controller is electrically connected with the movable potting mechanical arm, a first rotating motor, a second rotating motor, a first linear motor, a second linear motor and a third linear motor. The adjusting-type automatic potting machine has the beneficial effects of being simple in structure and high in practicability.
