Abstract

The invention is to maintain the master material intensity as the shaft of the double-face stator when using the double faces of the magnet and reduce the gap at the same time. The linear motor has: stator containing the permanent magnet arranged in parallel along the shaft direction; and a plurality of promoters respectively moving along the double faces of the stator. The stator comprises a shift intensity element extending along the shaft direction and a permanent magnet in the shift intensity element.

Description

technical field [0001] The present invention relates to a linear motor and a component mounting device, in particular to a linear motor with a double-sided stator suitable for the component mounting device, and a component mounting device with the linear motor. Background technique [0002] There is known a component mounting device that automatically mounts electronic components such as ICs, resistors, and capacitors on printed circuit boards, ceramic substrates, and the like. [0003] As such a component mounting device, Patent Document 1 discloses a configuration in which a mounting head having a suction nozzle for suctioning and holding an electronic component is configured to be movable in the X-axis direction by a linear motor. [0004] However, in shaft drive systems using linear motors, magnets are often used as stators and coils are used as movers. This is because usually the mass of the magnet is relatively large, so it is not suitable as a mover. [0005] In the...
