Abstract:
1. A solder paste mixer comprising: a housing defining a receiving space; a vibration mechanism comprising a hollow casing defining an accommodating space, a support member secured to a bottom of the accommodating space, an electromagnetic member fixed to the support member, and a vibration member that is made of material capable of being attracted by the electromagnetic member, wherein the vibration member comprises a main body aligned with the electromagnetic member and a plurality of bars radially extending from a lateral surface of the main body, each bar comprises an elastic arm extending therefrom, and the elastic arm comprises a distal end always contacting the support member for supporting the vibrating member and capable of being elastically deformed when the vibration member being attracted by the electromagnetic member; a rotating mechanism retained within the receiving space; and a fixture to fix a solder paste jar, wherein the fixture is capable of being rotated by the rotating mechanism, and when a voltage applied to the electromagnetic member varies, the vibration member vibrates the fixture in a corresponding amplitude and frequency as attracted by the electromagnetic member and resisted by the elastic arms of the plurality of bars.
