Numerous embodiments are disclosed. In one, a laser-processing apparatus includes a workpiece handling system having an unwind assembly including an unwind spindle operative to support an unwind material roll of a workpiece, and a rewind assembly including a rewind spindle operative to support a rewind material roll of the workpiece and receive the workpiece from the laser-processing apparatus. In another, a laser-processing apparatus includes a workpiece handling system having a web handling assembly attached to an upper structure configured to support an unwind spindle supporting a unwind material roll of a workpiece, wherein the web handling assembly is positioned within a space above the fixture. The laser-processing apparatus further includes a web tensioner assembly configured to apply a biasing force on the tensioning roller to maintain the workpiece in a desired state of tension.

A method of operating a welding torch using a rotating coupler assembly that operates between 0 and 800 amps. The rotating coupler assembly allows for 360 degrees of rotation while keeping rotational friction at a minimum. The breakaway torque for the rotating coupler assembly is insignificant and the rotating coupler assembly can be rotated with little effort by hand. While the rotating coupler assembly minimizes rotational friction the design allow for rotating coupler assembly to continue to operate after 1-5 mm of wear on the contact surfaces. An embodiment of the rotating coupler assembly can be quickly disconnected from the unicable.

A signal module and a signal relay device that can suppress the effect of noise are provided, and the signal module is a signal module of a tool changer including a first coupling member to be detachably attached to a body side of an industrial robot and a second coupling member to be detachably attached to a tool side, the signal module including a signal relay connector attached to the first coupling member or the second coupling member, and upon the first coupling member and the second coupling member being coupled, forming a signal path between the first coupling member side and the second coupling member side, wherein in the signal relay connector, a plurality of terminal pairs to be used for communication using differential signals are provided, and two terminals of each of the terminal pairs are arranged at mutually-adjacent positions.

A spark absorbing system for use with a cutting torch, comprises a cap having at least one spark opening therethrough and a spark capture unit coupled to the cap and positioned to capture sparks passing through the spark opening. The spark capture unit may comprise a tube extending from the cap and may include an outlet and a flow-reduction element positioned between the cap and the outlet and/or a spark accumulator between the cap and the spark capture unit. The flow-reduction element may comprise at least one baffle, screen or mesh. The spark absorbing system may further include a spark ramp extending from the cap opposite the spark capture unit and/or a shield, which may define a cutting space between the shield and the cap.

A composite printing device featuring multi-spindle high-energy-particle-beam deposition welding and milling, comprising a machine base, a workbench, a multi-spindle milling device, the multi-spindle milling device including a milling base and a tool base; the workbench including an ejector base, the ejector base fitted with a welding gun. Through the guide of the first rail and second rail, the horizontal distance between the milling base and the workbench or the ejector base can be adjusted, so that the milling base can move to the upper side of the workbench or ejector base; and the milling clamp can hold the tool or welding gun to form a one-layer or multi-layer approximate shape on the workbench and to conduct profile milling, so as to obtain the right size and surface accuracy required for the mechanical part, removing the need for further processing.

A rotary grip (9) grips a nozzle (11) in a component replacement area (V2) in a forward rotation or in a reverse rotation about a central axis of the nozzle (11). A rotary storage (4) stores a plurality of nozzles (11) at predetermined intervals in a circumferential direction about an axis of rotation (C1) and moves each of the plurality of nozzles (11) to a component supply area (V1) by rotating about the axis of rotation (C1).
