The invention discloses an automatic resistance value sorting device and sorting process. The device comprises a sorting rotating disc; and a first positioning air cylinder, a second positioning air cylinder and a third positioning air cylinder are fixed on air cylinder fixing bases, the first positioning air cylinder is connected with the first air cylinder fixing base through an action end, thesecond positioning air cylinder is connected with the second air cylinder fixing base through an action end, the third positioning air cylinder is connected with the third air cylinder fixing base through an action end, the first air cylinder fixing base is connected with a first negative pressure feeding air cylinder through a screw, the first negative pressure feeding air cylinder is connected with a negative pressure suction cup through an action end, and a fourth negative pressure feeding air cylinder is connected with the negative pressure suction cup through an action end. The device andthe process has the characteristics that vibration hopper automatic layout design is adopted, the layout automation is realized, the resistance values can be automatically sorted, the operation is simple, the resistance values are accurate, the percent of pass is high, the efficiency is high, the equipment is suitable for mass detection, the defect of manual sorting is overcome, the manual work is replaced by machines, and the labor cost is reduced.
