The invention relates to the technical field of pressing devices, in particular to an online type component pressing machine comprising pressing devices. Each pressing device comprises a machine table, a pressing appliance installed on the top of the machine table, a jig installed on the top of the machine table, a conveying device and a lifting drive mechanism installed on the machine table. Theconveying device is used for conveying products, to be subjected to component pressing, to the jig or outputting the products, subjected to component pressing, borne by the jig. The jig is located below the pressing appliance. The pressing appliance and the jig are used in cooperation to conduct pressing on the products, to be subjected to component pressing, borne by the jig. The online type component pressing machine is simple in structure, online type pressing of components and the products is achieved, the feeding, pressing and discharging work can be automatically completed, the period during which the components are pressed on the products is shortened, the component pressing efficiency is improved, the labor cost is reduced, the labor intensity is lowered, and the quality of component pressing conducted on the products is ensured.
