A conveyor system conveys devices for receiving components to be welded together, especially for internal combustion engine exhaust systems, into and out of a welding cell. The conveyor system includes a conveying vehicle (62) with a chassis (64) that can travel on a subfloor via rollers (68). A superstructure (78) is carried vertically adjustably on the chassis (64). At least one device carrier (14) receives components to be welded together in a position intended for the welding together in relation to one another. A positioning/holding formation (94) is provided on the superstructure (78) and a counter-positioning/holding formation (103) that meshes or can be caused mesh with the positioning/holding formation (94) is provided on the device carrier (14) for presetting a conveying position of the device carrier (14) on the superstructure (78).

Exemplary embodiments provide an apparatus to manufacture a mask frame assembly, including: extending unit configured to extend both ends of a mask in a first direction and arrange the mask on a frame, the mask including a deposition pattern and the frame including an opening; a pressurizing unit including a plurality of pressing portions the plurality of pressing portions configured to independently press the mask toward the frame; and a welding unit configured to weld the mask to affix the mask onto the frame.

A tool storage system has a universal mounting bracket coupled to a support surface formed with a plurality of apertures that align with differently sized support arms that support a tool therefrom. The apertures are aligned along a common horizontal plane and the support arms have different heights that allow tools to be hung therefrom in a nesting relationship so that more tools can occupy less space or area relative to the support surface. The nesting relationship of the tools provides for a first tool supported by the first arm to fit within a space defined by the second tool supported by the second arm. In some instance, the first and second arms may be part of a pair of support arms, respectively.

A welding window device includes an elongated body that defines a welding cavity that extends through the body from a top side to a bottom side. The welding cavity is framed by an inlet end, an outlet end, and lateral sides of the body. The body includes one or more gas channels inwardly extending through one or more of the first lateral side or the second lateral side from an inlet opening in the inlet end toward the outlet end of the body. The gas channels include nozzle openings inwardly oriented toward the welding cavity. The gas channels are positioned in the body to direct a gas into the welding cavity during welding of other bodies together within the welding cavity.

A method of securing a fastener to a workpiece includes a fastener that is loaded into a feeder, and an insertion head assembly that is provided adjacent to the feeder. The insertion head assembly includes an insertion actuator that has a movable insertion piston, and a clamp finger that is mounted to the insertion piston. The fastener is arranged beneath a movable fastener joining element that is carried by the insertion head assembly, the workpiece is positioned relative to a locating pin, the insertion head assembly is moved to engage the workpiece with the clamp finger, the fastener is brought into engagement with a locating pin, the fastener joining element is advanced relative to the clamp finger, and the fastener that is secured to the workpiece.

A method and apparatus for performing manufacturing functions on a workpiece. The apparatus may comprise a base, a plurality of autonomous functional components, and a plurality of autonomous movement systems. Each functional component of the plurality of autonomous functional components may be configured to perform a respective function. The plurality of autonomous movement systems may be associated with the base. Each of the plurality of autonomous movement systems may be connected to a respective functional component of the plurality of autonomous functional components.

A welding unit for welding together two rails of a track includes two rail clamping assemblies which can be moved towards one another in a longitudinal direction of the rail along unit guides by compression cylinders. Each rail clamping assembly is equipped with clamping jaws which are displaceable in pairs in a pressing plane and each of which has a contact surface provided for application to a rail web. The clamping jaws are each constructed as clamping levers which are pivotable in the pressing plane about a lever pivot axis. The contact surface intended for application to the rail web is disposed at a first lever end spaced apart from the lever pivot axis. The two contact surfaces of each rail clamping assembly are each positioned closer to the oppositely disposed rail clamping assembly than the two lever pivot axes.

A tool storage system has a universal mounting bracket coupled to a support surface formed with a plurality of apertures that align with differently sized support arms that support a tool therefrom. The apertures are aligned along a common horizontal plane and the support arms have different heights that allow tools to be hung therefrom in a nesting relationship so that more tools can occupy less space or area relative to the support surface. The nesting relationship of the tools provides for a first tool supported by the first arm to fit within a space defined by the second tool supported by the second arm. In some instance, the first and second arms may be part of a pair of support arms, respectively.

One or more clamping aid tools for mounting to various squares and straight edges, including carpenter squares, framing squares, speed squares or the like, and various straight edges and rulers for easily and accurately positioning various objects, either flat and/or round, magnetic or not. The clamping aid tools can secure these squares and straight edges to various objects while they are being fitted, secured and/or welded together.

A system for laser bonding of flip chip, and more particularly, to a system for laser bonding of flip chip for bonding a flip chip-type semiconductor chip to a substrate by using a laser beam is provided. According to the system for laser bonding of flip chip of the present disclosure, by performing laser bonding on a substrate while pressurizing semiconductor chips, even semiconductor chips which are bent or likely to bend may be bonded to the substrate without causing poor contact of solder bumps.
