The invention discloses an LED support full-automatic detection machine and relates to the technical field of LED detection devices. A fixing support is arranged inside an upper box body, wherein a material inlet rail is arranged longitudinally in the middle of the fixing support. A Y-axial driving support is connected to the lower end of the material inlet rail. An X-axial driving support is arranged at the left side of the material inlet rail. A light source and a CCD detection apparatus are fixed on the X-axial driving support and are arranged correspondingly to the material inlet rail. A material dividing spindle module is arranged on the top of the material inlet rail. A material box magazine is disposed behind the material dividing spindle module. A paper adding air cylinder module is arranged on the front end of the material box magazine. The detection machine is operated mechanically and a material is automatically collected by the machine, after automation detection, the materials are classified according to grade and then are automatically stored and packaged. The whole process is quick, accurate and unmanned, can be connected to a production line for detection and also can be independently operated as a detection machine.
