The application discloses a full automatic crystalline grain detection and sorting all-in-one machine. The all-in-one machine comprises nine main parts, i.e. a wafer workbench, a sorting workbench, a detection workbench, a transmission system, a wafer workbench pushing device, a sorting workbench pushing device, a detection workbench pushing device, a swing arm mechanism and a chip sorting storage. The all-in-one machine disclosed by the application ameliorates the traditional arrangement and the mechanical structure of the prior art, takes and places corresponding disk sheets via that the disk sheets freely pass in and out between the workbenches and the chip sorting storage via the transmission system and the pushing devices, and synchronously achieves the detection and the sorting of crystalline grains; and meanwhile, the transmission system is provided with two buffer area positions, can reduce the time of an exchange between disk sheets to be sorted and sorted disk sheets and another exchange between the disk sheets to be detected and detected disk sheets, and further accelerates the time and the efficiency of the sorting and the detection of the crystalline grains. The full automatic crystalline grain detection and sorting all-in-one machine has the characteristics of efficient disk sheet exchange, smart whole machine, impact structure, and good stability of the whole machine and expansion performance of the chip sorting storage.
