Title:
COIL UNIT FOR MULTI-AXIS LINEAR MOTOR ACTUATOR, AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/215074
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a coil unit that is suited to the bulk manufacturing of multiple sets of coil parts for a multi-axis linear motor actuator. This method of manufacturing a coil unit for a multi-axis linear motor actuator, which is constituted by disposing multiple sets of linear shaft motors 10 in a line at a prescribed pitch, includes: a step in which a coil fixing member 50 is prepared that holds receiving parts 51 that are capable of receiving multiple coil parts 15, which are equal in quantity to the multiple sets of linear shaft motors, with the coil parts being arranged in a line at the prescribed pitch; a step in which the multiple coil parts are disposed by being arranged in a line and secured to the coil fixing member; and a step in which electromagnetic shielding plates 70 that are longer than the coil parts are disposed along a central axis direction at locations corresponding to the spaces between at least adjacent coil parts among the multiple coil parts disposed in the line.
