The invention relates to a self-contained vacuum source negative pressure adsorption module. Three vacuum chucks are connected together through the module, and a self-contained vacuum pump of the module simultaneously vacuumizes to form negative pressure. The module mainly comprises the vacuum chucks, a one-way valve, the vacuum pump, a main bracket, a vacuum pressure sensor, a two-position two-way vacuum solenoid valve, a connecting frame, an air pipe, and the like. The two-position two-way vacuum solenoid valve controls the communication between inner cavities of the three vacuum chucks and the atmosphere; during non-communication, the vacuum chucks and the adsorbed surface form a sealed cavity, and the vacuum pump works to make the negative pressure formed in the cavity so as to generate the adsorption function; and during communication, the negative pressure of the vacuum chucks is relieved so as to separate the module from the adsorbed surface. The module has the advantages of simple structure, self-contained property, independent completion, and convenient connection with other modules or components, and can be used as an adsorption foot of a wall climbing robot or an end executor of a manipulation arm.
