  • Patent number: 11975364
    Abstract: A component transfer device includes an integration path through which both of a regular component and a defective component are to be transported, and a sorting gauge that is provided at the downstream end of the integration path and sorts the regular component and the defective component. A discharge path through which the defective component passes extends to incline in the width direction of the integration path. The sorting gauge includes a gauge body, a sorting path extending through the gauge body and into which the regular component is allowed to advance while the defective component is not allowed to advance, and a guide surface that is disposed at the gauge body so as to spread toward the discharge path and that guides the defective component to the discharge path when the defective component comes into contact with the guide surface.

  • Patent number: 11707795
    Abstract: A plate thickness test mechanism includes a detection section that detects an abnormality when a plate thickness is thinner than a desired plate thickness by a predetermined amount or more or thicker than the desired plate thickness by the predetermined amount or more, a determination section that determines whether or not the detection section functions normally, and a plate-shaped test jig that has a first plate portion having a plate thickness thinner than a predetermined specific plate thickness, and a second plate portion having a plate thickness thicker than the specific plate thickness. The determination section determines whether or not a plate thickness test is normally performed on the basis of a detection result of the detection section obtained when the detection section tests the plate thicknesses of the first and second plate portions by taking the desired plate thickness as the specific plate thickness.

  • Publication number: 20210086365
    Abstract: Actual coordinate system data is acquired on the basis of a coordinate position at which a coordinate system generating tool attached to a robot is brought into proximity to, or contact to a coordinate system generating target of a coordinate system generating unit attached to a work piece positioning device. Simulation teaching data of a movement trajectory of a welding gun and design coordinate system data based on a design coordinate value of a coordinate system generating target are acquired by using a virtual model. After the actual coordinate system data is acquired into an information processing system, a coordinate position of the simulation teaching data is then moved to match the design coordinate system data with the actual coordinate system data.

  • Patent number: 10688594
    Abstract: Provided is a device for assembling a fuel supply pipe of which a joint portion between a pipe body and a short cylindrical member has a high strength and which has high anti-corrosion performance. Specifically, while a laser beam in a defocused state is being emitted to impinge on an end portion of the pipe body that overlaps the short cylindrical member, the pipe body and the short cylindrical member are rotated through one complete turn relative to the laser beam, thereby melting the entire periphery of the end portion. While the laser beam in a defocused state is being emitted to impinge on the melted end portion, the pipe body and the short cylindrical member are rotated through at least one further complete turn, thereby joining by welding the end portion to the outer periphery of the short cylindrical member.

  • Patent number: 8955559
    Abstract: Fuel vapor is prevented from leaking to the outside during refueling, and even when an air space is formed in an upper portion of a fuel filler pipe, a diagnosis of leakage of fuel vapor can be performed with good accuracy. During refueling, fuel vapor is guided from a fuel tank 1 to a canister 3, and is absorbed by the canister 3. A change in the internal pressure of a fuel vapor path including the fuel tank 1, a fuel vapor pipe 4, and the canister 3 is detected by a pressure sensor 8, thereby performing a diagnosis of leakage of fuel vapor. An upper space 16 in the fuel tank 1 and an upper space 17 in a fuel filler pipe 2 communicate with each other through an airflow resistance pipe 12, and in order to restrict flow of fuel vapor from the fuel tank 1 through the airflow resistance pipe 12 into the fuel filler pipe 2 during refueling, the airflow resistance pipe 12 includes an orifice 13.
