  • Patent number: 11220011
    Abstract: Provided is a multi-jointed welding robot that includes: a rotating part that is rotatably provided on a base that is fixed to an installation surface; and a multi-jointed arm that is coupled to the rotating part via a first driving shaft and has a plurality of arm parts. An opening is formed in the rotating part through which a routing member, which is routed inside the rotating part, is guided from part of the rotating part toward the side opposite the installation surface. A guide member guides the routing member, which has one end fixed to the opening and which is guided through the opening, toward the installation surface from the other end of the routing member while bending the routing member.

  • Patent number: 11141869
    Abstract: A harness connection structure has a first arm; a second arm which has a base side that is rotatably coupled to the first arm via an arm joint; and a harness that extends from a leading end of the first arm and is guided into an arm interior at the arm joint. The leading end of the first arm has a harness holding part that holds one longitudinal side of the harness. The arm joint has a harness fixing part that fixes the other longitudinal side of the harness inside the arm joint. The harness fixing part is disposed such that the harness is inclined from the longitudinal axis of the second arm toward the leading end of the first arm.

  • Patent number: 10843334
    Abstract: A mechanical stopper device wherein a fixed body includes a fixing-side stopper, including: a lever that can swing about a supporting shaft provided to the fixed body; and a pair of elastic bodies, attached to the fixed body, on both sides in the lever swinging direction, and which can contact with both side surfaces of the lever. Further, a rotating body includes a stopper pin that can be in contact with both the side surfaces of the lever. The ratio between a distance (a) from a supporting point of the lever to a contact position where the lever and the stopper pin are in contact with each other, and a distance (b) from the supporting point of the lever to a contact position where the lever and the elastic bodies are in contact with each other is 1.05?a/b?2.30, and thickness (D) of the elastic bodies is 20 mm?D?40 mm.

  • Publication number: 20190047073
    Abstract: A welding apparatus includes an articulated robot having a plurality of drive shafts, an end effector supported by the articulated robot, a tip shaft drive mechanism, and a drive control unit. The tip shaft drive mechanism is provided between a tip drive shaft of the articulated robot and the end effector and allows a tip shaft of the end effector to perform a weaving operation. The drive control unit drives the articulated robot and the tip shaft drive mechanism. The tip shaft drive mechanism includes a first-axis drive unit which drives the tip shaft in a first-axis direction that is perpendicular to the tip shaft of the end effector and a second-axis drive unit which drives the tip shaft in a second-axis direction that is perpendicular to the tip shaft and the first-axis direction.
