Problems solved by technology
[0006] However, in order to securely fix the core of the stator to the frame member so as to properly maintain the gap between the stator and the mover, the screwing depth of the bolts for fixing the core of the stator cannot be shortened beyond a certain limit.
That is, there is a limit to the reduction of the thickness dimension of the frame member
[0007] Moreover, in the above-mentioned linear motor unit, the bolts of the linear motors arranged in the width direction are located on the same axis with each other. Therefore, in order to prevent the adjacent bolts from contacting each other or the bolts from the adjacent frame The members are in contact with each other, and it is necessary to provide a gap between them, which also makes it difficult to miniaturize (thin) the linear motor unit

The invention relates to a linear motor unit, a head unit and a component mounting device, wherein the linear motor unit comprises first and second motors and a mounting frame. The first and second motors have stators and movers, the movers being controlled by energization based on a coil and thus can move relative to the stators, and are parallely mounted on the mounting frame along a direction perpendicular to a first direction of the stators perpendicular to a relative direction of the movers. The mounting frame comprises mounting parts used for fixing stators of the linear motors, and the mounting part are arranged in such a way that the stators of the linear motors and the mounting parts alternately arranged along the first direction. The stators of the linear motors are at different positions of a second direction perpendicular to the first direction, and are fixed to the mounting parts through fastening cores with the mounting parts by using specified fastening members along the first direction, thereby realizing miniaturization of the linear motors.
Description
Technical field [0001] The invention relates to a linear motor unit, a head unit and a component mounting machine. Background technique [0002] As a component mounting machine that mounts electronic components such as IC chips on a printed circuit board or the like, there is known a component mounting machine disclosed in Japanese Patent Laid-Open No. 2009-171681 (hereinafter referred to as "Patent Document"). The component mounting machine includes a head unit having a plurality of suction nozzles for sucking electronic components, and the suction nozzles are arranged along the width direction of the head unit. In the head unit, a linear motor unit that moves the suction nozzle up and down is assembled, and the linear motor unit includes a plurality of linear motors arranged in the width direction corresponding to each suction nozzle. [0003] Each linear motor includes a stator and a mover that can move in the vertical direction while facing the stator. The stator includes a m...
