ELECTRONIC CIRCUIT COMPONENT MOUNTING HEAD

摘要

An electronic circuit component mounting head which mounts electronic circuit components to a circuit substrate is provided. The mounting head includes a rotating/raising/lowering axis held on a head main body as to be capable of rotation and of being raised/lowered, a suction nozzle held on the rotating/raising/lowering axis as to be capable of being raised/lowered and not capable of being rotated relatively, and the rotating/raising/lowering axis and suction nozzle can be rotated as necessary by an electric motor. A raising/lowering driving member is held on head main body as to be capable of being raised/lowered, and is raised/lowered by a first linear motor. A first engaging section of the raising/lowering driving member is engaged with the rotating/raising/lowering axis, and a second engaging section of a second linear motor is held on the raising/lowering driving member engaged with suction nozzle.

主权项

1. An electronic circuit component mounting head comprising:
a head main body; a raising/lowering member which is guided on the head main body as to be capable of being raised/lowered; a first raising/lowering driving device which raises/lowers the raising/lowering member with respect to the head main body; a component holding tool which holds an electronic circuit component and is held as to be capable of being raising/lowered relative to the raising/lowering member by the raising/lowering member; a second raising/lowering driving device which is raised/lowered together with the raising/lowering member by the first raising/lowering driving device and which raises/lowers the component holding tool relative to the raising/lowering member; and a biasing device provided between the raising/lowering member and the component holding tool, the biasing device biases the component holding tool either up or down relative to the raising/lowering member, wherein the second raising/lowering driving device engages with the component holding tool against the biasing force of the biasing device without acting via an elastic member, and in that state, the second raising/lowering driving device mounts an electronic circuit component on a circuit substrate.
