Linear motion device and electronic component mounting device

A linear motion device, comprising:

• a base that extends in a reference direction;
• a linear guide mechanism that includes
• a guide rail fixed to the base and extending in the reference direction, and
• a slider supported movably on the guide rail along the reference direction;
• a moving body that is fixed to the slider and that is movable in the reference direction together with the slider;
• a linear motor that includes
• a stator fixed to the base, the stator including a magnet row and extending in the reference direction, and
• a mover including a plurality of coils provided with a certain gap from the stator;
• and
• a heat transfer body that is disposed between the moving body and the mover and that is connected to the moving body and the mover,
• wherein the heat transfer body extends in a direction away from the linear guide mechanism,
• wherein the heat transfer body has a first surface facing the moving body, and
• wherein the first surface is a mirror surface.

A linear motion device that moves a moving body by a linear motor, when a moving direction of the moving body is defined as an X direction, a horizontal direction perpendicular to the X direction is defined as a Y direction, and a direction perpendicular to the X direction and the Y direction is defined as a Z direction, the linear motion device comprising:

• a base that extends in the X direction;
• a linear guide mechanism that includes
• a guide rail fixed to the base and extending in the X direction, and
• a slider supported movably on the guide rail along the X direction;
• the moving body that is fixed to the slider and that is movable in the X direction together with the slider;
• the linear motor that includes
• a stator fixed to the base, the stator including a magnet row and extending in the X direction, and
• a mover including a plurality of coils provided with a certain gap from the stator;
• and
• a heat transfer body that is disposed between the moving body and the mover in the Y direction and that is connected to the moving body and the mover,
• wherein the linear motor is fixed to an upper surface of the base in the Z direction, and does not face the linear guide mechanism in the Y direction, and
• wherein the heat transfer body is disposed above the linear guide mechanism in the Z direction, and does not face the linear guide mechanism in the Y direction,
• wherein the heat transfer body has a first surface facing the mover,
• wherein the first surface is coated with a substance that absorbs radiant heat from the mover, and
• wherein the substance is a blackbody coating material or alumite.
