A method of customizing a vehicle body includes inputting a selected customized embellishment to a laser controller, directing a beam of the laser onto a surface of the vehicle body, and guiding the beam of the laser with the laser controller to impart the selected customized embellishment to the surface.

In a laser cutting method, a cut slit of a welding protruding-tab configured to be bent by laser cutting along an outline of a processed part and press a peripheral surface of the processed part is laser-cut in advance in a periphery of the processed part that is cut from a workpiece, and an outline slit is formed by performing laser cutting along the outline of the processed part and a free end of the welding protruding-tab is welded to the peripheral surface of the processed part. According to the above described laser cutting method, it is possible to retain the processed part reliably and stably for a long period, and it is possible to easily separate the processed part from the workpiece with almost no trace left on the processed part.

-- A method for welding together two parts along a weld line using a welding system enabling an operator to remotely perform welding operations. The operator defines reference points on the parts to be welded and/or on the weld line to be followed. A general movement direction of the welding torch is defined from the reference points. A local frame of reference is defined relative to the general movement direction of the welding torch. The welding torch is automatically moved from a welding starting point in the general movement direction. A flow of movement instructions linked to actions of the operator on the human-machine interface is generated to move the welding torch away from the general movement direction to adapt a trajectory of the welding torch to an actual shape of the weld line. The welding torch is moved corresponding to the flow of instructions generated by the human-machine interface.

A method for separating a workpiece having a transparent material includes providing ultrashort laser pulses using an ultrashort pulse laser, introducing material modifications into the transparent material of the workpiece along a separation line, and separating the material of the workpiece along the separation line. The laser pulses form a laser beam that is incident onto the workpiece at a work angle. The material modifications are Type III modifications associated with a formation of cracks in the material of the workpiece. The material modifications penetrate two sides of the workpiece that are located in intersecting planes. Separating the material of the workpiece produces a chamfer and/or a bevel. A length of a hypotenuse of the chamfer and/or bevel is between 50 μm and 5000 μm.

Provided is a laser processing system with which correction of a control point can be carried out easily. This laser processing system is provided with a scanner capable of scanning a workpiece with laser light, a moving device for moving the scanner relative to the workpiece, and a scanner control device for controlling the scanner, wherein the scanner control device has a trajectory control unit for controlling the scanner such that the workpiece is irradiated with a control point correction trajectory for correcting a preset control point when the movement device is in a stopped state, and the control point correction trajectory has a prescribed length for specifying deviation of the laser light in the optical axis direction, and a prescribed shape for specifying the position of the control point and a direction of a coordinate system defined by the control point.

A galvano scanner that performs scanning with a laser beam according to the present invention includes a galvano unit having a mirror and a mirror drive mechanism, a base member on which the galvano unit is mounted, an outer peripheral member disposed so as to surround the galvano unit, and a frame member to which the base member and the outer peripheral member are attached, and is configured such that the base member and the outer peripheral member are attached to the frame member via a sealing member.

Disclosed are a welding system and a welding method using the same. The welding system may include: a main conveyor configured to convey a battery palette on which a battery module assembly is mounted; at least two auxiliary conveyors disposed in parallel with the main conveyor; a loading-unloading module configured to transfer the battery palette, which is conveyed along the main conveyor, to the auxiliary conveyor and transfer the battery palette, which is completely subjected to a preset welding process, from the auxiliary conveyor to the main conveyor; clamping jigs on which the battery palettes are seated by the loading-unloading module so that the preset welding process is performed on the battery module assemblies on the auxiliary conveyors; and at least two welding robots configured to weld the battery module assemblies seated on the at least two auxiliary conveyors.

A method, system and devices for autonomous marking of a substrate and for conducting formability measurements. The method, system and devices may be used to apply markings to a substrate, such as panels that are used to construct articles. The panels, for example, may be automobile panels. The markings preferably are applied on the panel autonomously with a laser etching, and with robot device that is controlled to form a precise pattern of indicia (e.g., dots), on the panel surface. An x, y, z, gantry coordinate system may be used to guide the operations of the robot device to position the device for etching at precise locations on the substrate surface. Once etched, the panels may be processed, such as, by stamping or cutting, and the deformation of the dot pattern may be used to determine strain and formability properties.

Systems and methods for real time feedback and for updating welding instructions for a welding robot in real time is described herein. The data of a workspace that includes a part to be welded can be received via at least one sensor. This data can be transformed into a point cloud data representing a three-dimensional surface of the part. A desired state indicative of a desired position of at least a portion of the welding robot with respect to the part can be identified. An estimated state indicative of an estimated position of at least the portion of the welding robot with respect to the part can be compared to the desired state. The welding instructions can be updated based on the comparison.
