An apparatus for automatic placement of gaskets on a housing includes a base, the second feeding mechanism, a first detecting member, a bearing mechanism, an assembly mechanism, and a controller. The first detecting member can detect the position of the gaskets relative to the preset position. The detected results are transmitted to the controller by the first detecting member. The controller controls the second feeding mechanism to accurately adjust the position of the gaskets to preset position. Therefore, a projection of the gasket is accurately engaged in a mounting hole of the housing by the assembly mechanism.
