Publication number: 20220361386Abstract: In a component adsorption nozzle, the nozzle can be attached to both of the in-line shaft and the rotary shaft by utilizing the outside (outer wall) of the nozzle body for attaching to the in-line shaft and utilizing the inside (inner wall) of the nozzle body for attaching to the rotary shaft. Therefore, for a user who owns each of the in-line type and rotary type component mounters, it is not necessary to prepare a nozzle dedicated to each type component mounter and it is possible to reduce the burden required for preparing the nozzle.Type: ApplicationFiled: September 25, 2019Publication date: November 10, 2022Applicant: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventor: Kenji TSURI

Patent number: 10897841Abstract: A rotary head of a surface mounter includes a rotating body, an N-shaft servo motor configured to rotate and drive the rotating body and a plurality of suction nozzles attached to the rotating body in such a manner as to be movable in a direction of a rotation axis. The plurality of suction nozzles are arranged on a virtual circle with the rotation axis as the center, and the plurality of suction nozzles are configured to hold and release a component. The rotary head of a surface mounter further includes a Z-axis drive device including a Z-axis linear motor. The Z-axis drive device is configured to use the Z-axis linear motor to move, in the direction of the rotation axis, the suction nozzle that has moved to a predetermined drive position on the virtual circle.Type: GrantFiled: October 1, 2015Date of Patent: January 19, 2021Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Kenji Tsuri, Tomoyoshi Utsumi

Patent number: 10849259Abstract: A mounting head includes a pickup nozzle, a shaft member, a drive unit, and a position retainer. The shaft member has a cylindrical shape and moves in an axial direction to switch a pressure applied to the pickup nozzle between negative and positive pressures. First and second movement ends in the axial direction are negative and positive pressure application positions, respectively, where negative and positive pressure, respectively, is applied to the pickup nozzle. The drive unit includes a drive source that moves a movable portion in the axial direction. The movable portion contacts the shaft member when moved in the axial direction, to move the shaft member between the negative and positive pressure application positions. During a power-off period of the drive source, the position retainer holds the movable portion in a predetermined position away from the shaft member located at the negative or positive pressure application positions.Type: GrantFiled: October 1, 2015Date of Patent: November 24, 2020Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventor: Kenji Tsuri

Publication number: 20180279520Abstract: A mounting head includes a pickup nozzle, a shaft member having a cylindrical shape and movable in an axial direction thereof to switch pressure applied to the pickup nozzle between negative and positive pressures, and a drive unit including a drive source, a movable portion movable in the axial direction using drive source power, and a cam follower on the movable portion. The shaft member has two opposing portions extending in a direction intersecting the axial direction and facing each other with a space therebetween, with the cam follower between the two opposing portions. The drive unit moves the movable portion in the axial direction to perform first and second movement operations in which the cam follower is brought into contact with one or the other of the opposing portions to move the shaft member to one side or the other side, respectively, in the axial direction.Type: ApplicationFiled: October 1, 2015Publication date: September 27, 2018Applicant: Yamaha Hatsudoki Kabushiki KaishaInventor: Kenji TSURI
