Automatic dispensing machine

An automatic dispensing machine adapted for dosing adhesive to a product includes a base frame having a flat operating platform, at least two positioning apparatuses disposed on the operating platform for securing the product respectively, a sliding support slidably mounted onto the base frame and capable of being driven to slide above the positioning apparatuses, and a storage container vertically slidably mounted onto the sliding support by means of a container stand for storing the adhesive and capable of being driven by the sliding support to suspend over another one of the positioning apparatuses from one of the positioning apparatuses for dosing the adhesive to the product. When the automatic dispensing machine processes the product positioned in another positioning apparatus, the former processed product secured on one positioning apparatus can be simultaneously disassembled therefrom and another product is repositioned to the one positioning apparatus.
