Disclosed is a workpiece receptacle, in particular for an ultrasonic welding device, that has a receiving element for receiving a workpiece. The receiving element can be moved in relation to a base element. A bearing device is disposed between the receiving element and the base element for this purpose. The bearing device has spherical surfaces lying opposite one another.

Techniques and devices are disclosed for fabrication layout device. The device includes a table with a work surface. The work surface being a continuous surface and configured to support a plurality of railing pieces for fabrication of a railing assembly. The device further includes a beam located above the work surface. The beam is operatively coupled to the table, such that the beam moves relative to the work surface in a first direction. Attached to the beam is an ink dispenser. The ink dispenser is configured to move along the beam in a second direction different from the first direction. The ink dispenser is further configured to dispense ink onto the work surface of the table in the form of a pattern of the railing assembly. Railing pieces are positioned on the pattern so that they can be assembled to one another.

A processing apparatus is equipped with: a first stage system that has a table on which a workpiece is placed and moves the workpiece held by the table; a beam irradiation system that includes a condensing optical system to emit beams; and a controller to control the first stage system and the beam irradiation system, and processing is performed to a target portion of the workpiece while the table and the beams from the condensing optical system are relatively moved, and at least one of an intensity distribution of the beams at a first plane on an exit surface side of the condensing optical system and an intensity distribution of the beams at a second plane whose position in a direction of an optical axis of the condensing optical system is different from the first plane can be changed.

There are provided a stage for cutting a substrate, and a substrate-cutting apparatus. The stage includes a supporting member for having the substrate mounted thereon, including a plurality of cell areas, and defining a groove line having a groove shape between the plurality of cell areas, and a first tube line inserted into the groove line to contact an inner wall of the groove line, and having an open upper portion.

An embodiment of the present disclosure provides a welding fixture, including: a base; a supporter; a fixing device arranged to fix a member to be welded on the supporter; and a damping hinge which includes a first hinge plate, a second hinge plate and a pivot, the first hinge plate being fixed to the base, the second hinge plate being fixed to the supporter, wherein each of the first hinge plate and the second hinge plate has a pivot hole and is connected to the pivot via the pivot hole, and wherein the pivot is fitted into the pivot hole of each of the first hinge plate and the second hinge plate by interference. An embodiment of the present disclosure provides a welding method using the welding fixture.

Present invention consists of a block with a cylindrical stud and a cylindrical hole. A hex-head screw comprises a screw head portion, a middle portion and a threaded portion. The threaded portion of the hex-head screw can be fitted to the base of a clamp through the cylindrical hole, so that the clamp can freely rotate, using the cylindrical stud as a pivoting point, and the clamp's location on a welding table can be shifted to provide a proper location on the surface of a work piece.

A welding support block supports, from the rear surface of a joint to be welded, a weld pool created during a welding process. The welding support block comprises a block of metal and an outer layer of ceramic material providing a supporting surface. The ceramic material layer has a thickness between 0.25 mm and 1.5 mm. The metal material immediately beneath the ceramic material layer is made of steel. An internal line-up clamp for holding pipes in end-to-end alignment ready for welding may include multiple such welding support blocks. The use of such welding support blocks is particularly useful when laying a sour service carrying pipeline (high H.sub.2S content).

The laser processing machine includes a beam oscillation mechanism that oscillates a beam spot on a surface of a sheet metal. The control device controls the beam oscillation mechanism so as to oscillate the beam spot with an oscillation component in a direction orthogonal to a cutting direction of the sheet metal in a non-holding region, in which a holding portion of the conveyance apparatus for conveying a product is not held, when cutting the product from the sheet metal by irradiating the sheet metal with the laser beam. The non-holding region is at least a part of a periphery of a protrusion portion of the product, or at least a part of a periphery of a recess forming region in which a recess of the product is formed.

A jig apparatus is used for assembling a trunk lid including an upper panel, an extension panel, and a lower panel. The jig apparatus may include: a jig frame; a first activation jig unit configured to align and fix the upper panel and the extension panel and installed at the jig frame in front and rear directions to be tilting-rotatable; and a second activation jig unit aligning and fixing the lower panel and installed at the jig frame to be linearly movable in the front and rear directions with respect to the first activation jig unit.

A system and method for assembling a plurality of components into an assembly is provided. The system includes an assembling robot and an adhesive dispensing robot. The assembling robot is configured to attach a first sub-assembly to a second sub-assembly. The first sub-assembly includes at least one of the plurality of components, and the second sub-assembly includes remaining ones of the plurality of components. The adhesive dispensing robot is configured to apply an adhesive between the first sub-assembly and the second sub-assembly, after the first sub-assembly is attached to the second sub-assembly, to bond the first sub-assembly to the second sub-assembly.
