The present invention provides an automatic compounding device for improving operations of grinding a crucible, coating a mould release agent onto the crucible, and adding sulfide ore into the crucible. The automatic compounding device 1 of the present invention comprises: a grinding device 2, used for grinding a crucible 12 for compounding an analysis sample (such as a recycled material) and a flux; a coating device 3, used for coating a mould release agent onto the crucible 12 ground by the grinding device 2; a weighing device 4, used for adding iron sulfide into the crucible 12 coated with the mould release agent via the coating device 3; and a multi-axial robot arm 5, used for conveying the crucible 12 placed on a tray to the grinding device 2, conveying the ground crucible 12 from the grinding device 2 to the coating device 3, conveying the crucible 12 coated with the mould release agent from the coating device 13 to the weighing device 4, conveying the crucible 12 added with the sulfide ore from the wei
