Abstract: The stator assembling method includes: the step of disposing a guide to restrict circumferential movement of opening jigs inserted into slots; and the step of moving coils and the opening jigs together to a second side in a radial direction relative to a stator core while guiding the opening jigs such that circumferential movement of the opening jigs is restricted by the guide, thus inserting slot-housed portions into the slots.

Abstract: A stator assembly method of assembling a stator that includes a stator core that includes a slot that has an opening that opens on one side in a radial direction, a coil that includes a slot-housed portion housed in the slot, and insulation disposed between the slot and the slot-housed portion, the method including disposing the insulation in the slot; opening a portion of the insulation on the one side in the radial direction by inserting a first guide jig into the insulation, which is disposed in the slot, along a center axis direction of the stator core, after disposing the insulation; and inserting the slot-housed portion into the slot via the opening by moving the coil and the first guide jig together toward the other side in the radial direction with respect to the stator core, after opening the portion of the insulation.

Abstract: A caulking method includes: determining a caulking depth which becomes equal to or larger than a necessary release torque that has been set in advance, determining a stroke amount of a push-in part which becomes equal to or larger than the caulking depth that has been determined; determining the stroke amount of a drive unit which becomes equal to or larger than the stroke amount of the push-in part that has been determined, and controlling the drive unit at a target control stroke amount that is equal to or larger than the stroke amount of the drive unit that has been determined but is smaller than the stroke amount of the drive unit at which the caulk part is damaged.

Abstract: A laser dicing method for a substrate to be processed having a metal film on a surface thereof includes a metal film removing step for placing the substrate to be processed on a stage, irradiating the metal film with a defocused pulse laser beam, and removing the metal film, and a crack forming step for irradiating a region where the metal film is removed of the substrate to be processed with a pulse laser beam, and forming a crack in the substrate to be processed.

Abstract: Provided is a laser dicing method, including: loading a substrate on a stage; generating a clock signal; emitting a pulse laser beam synchronized to the clock signal; relatively shifting the substrate and the pulse laser beam; switching by the unit of an optical pulse irradiation and non-irradiation of the pulse laser beam to the substrate by controlling passage and interruption of the pulse laser beam by using a pulse picker in synchronization with the clock signal; and forming a crack reaching the surface of the substrate on the substrate, wherein the crack is formed to be continuous on the surface of the substrate by controlling irradiation energy of the pulse laser beam, a processing point depth of the pulse laser beam, and the lengths of an irradiation region and a non-irradiation region of the pulse laser beam.

Abstract: A laser dicing device is provided to perform dicing processing that has excellent cutting properties and is stable even when the dicing speed is changed.
