Patent number: 10958048Abstract: A peeling device (12) includes a first peeling unit (21) and a second peeling unit (22). When an upper peeling die (33) and a lower peeling die (34) of the first peeling unit (21) are moved forward, an insulating coating (8) is peeled off from upper and lower surface of a coil conductor wire (2), and a conductive portion (7) is cut from the upper surface and the lower surface of the coil conductor wire (2). The conductive portion (7) is formed to have exposed portions (7a) and recessed portions (7b) cut in a trapezoidal shape. A front peeling die (42) and a rear peeling die (43) of the second peeling unit (22) are moved downward while the recessed portion (7b) is placed on and pressed against a second receiving section (41b) of a cradle (41), which peels off the insulating coating (8) and cuts the conductive portion (7).Type: GrantFiled: February 6, 2017Date of Patent: March 23, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Masafumi Saito, Yoshiyuki Izumi, Kenichiro Murata, Eishi Yoshida, Toru Eguchi

Patent number: 10950000Abstract: A conductive-wire position inspecting device includes: a reference body disposed in a radial direction of a stator core; an imaging device configured to image a conductive wire and the reference body; and a calculating device configured to find a relative position and a relative angle of the conductive wire with respect to the reference body, based on an obtained image. In addition, the conductive-wire position inspecting device includes a determining device configured to determine whether or not the found relative position and relative angle are within respective permissible ranges, and if they are within the permissible ranges, determine the position of the conductive wire to be acceptable.Type: GrantFiled: February 12, 2020Date of Patent: March 16, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Hidetaka Hokazono, Yoshiyuki Izumi, Yasuyuki Kimura, Masahiko Kamiyama, Naoki Ito, Yutaka Matsumoto, Daisuke Ueno

Patent number: 10556297Abstract: The present invention relates to a welded section examining device. In order to examine whether welding is good or bad of a welded section joining tip portions of electrical conductors projecting from slots of a stator core, a welded section examining device includes a camera, a discriminating unit, a wavelength-converting sheet, and a masking member. The camera images the welded section. The discriminating unit performs discrimination of whether welding is good or bad based on an outline of the welded section recognized from an image of the welded section imaged by the camera. The wavelength-converting sheet irradiates the welded section with a light, from a rear surface side of an imaging target surface. The masking member is interposed between the wavelength-converting sheet and the rear surface of the welded section, such that the outline of the welded section is imaged in the camera in an emphasized state.Type: GrantFiled: December 27, 2018Date of Patent: February 11, 2020Assignee: HONDA MOTOR CO., LTD.Inventors: Masahiko Kamiyama, Tetsuya Ozawa, Atsuhiro Hatanaka, Yoshiyuki Izumi

Patent number: 7126246Abstract: Coils in respective poles are all wound in the same shape. The coils are wound such that one of the winding ends in a predetermined layers, for a single turn, is passes to an adjacent layer, or single turns at the winding ends in a predetermined layer are wound to different adjacent positions, whereby the cross-sectional shape of the coils is unsymmetrical. The coils are wound such that part of each coil crosses or contacts an intermediate line bisecting the angle formed between the axes of the coils.Type: GrantFiled: May 8, 2003Date of Patent: October 24, 2006Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yoshiyuki Izumi, Hiroshi Sakakibara
