摘要： A method includes receiving, during a vibration welding process, a set of sensory signals from a collection of sensors positioned with respect to a work piece during formation of a weld on or within the work piece. The method also includes receiving control signals from a welding controller during the process, with the control signals causing the welding horn to vibrate at a calibrated frequency, and processing the received sensory and control signals using a host machine. Additionally, the method includes displaying a predicted weld quality status on a surface of the work piece using a status projector. The method may include identifying and display a quality status of a suspect weld. The laser projector may project a laser beam directly onto or immediately adjacent to the suspect welds, e.g., as a red, green, blue laser or a gas laser having a switched color filter.

摘要： A system includes a host machine and a status projector. The host machine is in electrical communication with a collection of sensors and with a welding controller that generates control signals for controlling the welding horn. The host machine is configured to execute a method to thereby process the sensory and control signals, as well as predict a quality status of a weld that is formed using the welding horn, including identifying any suspect welds. The host machine then activates the status projector to illuminate the suspect welds. This may occur directly on the welds using a laser projector, or on a surface of the work piece in proximity to the welds. The system and method may be used in the ultrasonic welding of battery tabs of a multi-cell battery pack in a particular embodiment. The welding horn and welding controller may also be part of the system.

摘要： A method of resistance spot welding workpiece stack-ups of different combinations of steel workpieces and aluminum workpieces includes several steps. In one step, a workpiece stack-up is brought between a first weld gun arm and a second weld gun arm. The first weld gun arm includes a first welding electrode, and the second weld gun arm includes a carrier that supports a second welding electrode and a third welding electrode. Another step involves rotating the carrier and passing electrical current through the workpiece stack-up using the first welding electrode in conjunction with either the second welding electrode or the third welding electrode depending on which electrode has been rotated into facing alignment with the first welding electrode.

摘要： A system includes host and learning machines in electrical communication with sensors positioned with respect to an item of interest, e.g., a weld, and memory. The host executes instructions from memory to predict a binary quality status of the item. The learning machine receives signals from the sensor(s), identifies candidate features, and extracts features from the candidates that are more predictive of the binary quality status relative to other candidate features. The learning machine maps the extracted features to a dimensional space that includes most of the items from a passing binary class and excludes all or most of the items from a failing binary class. The host also compares the received signals for a subsequent item of interest to the dimensional space to thereby predict, in real time, the binary quality status of the subsequent item of interest.

摘要： A compliant end effector includes a robot mounting bracket and a component support member. The component support member includes a side surface and a top surface. A component clamping system includes a first clamp member operable to move toward the side surface of the component support member and a second clamp member operable to move toward the top surface of the component support member. A controller is operatively connected to the clamping system. The controller is configured to engage the first and second clamp members as the component gripping and manipulating system is in a set position and release the first clamp member and the second clamp member allowing a portion of a component held by the component clamping system to move with one or more degrees of freedom when the component gripping and manipulating system is moving to the set position.

摘要： A vibration welding system includes vibration welding equipment having a welding horn and anvil, a host machine, a check station, and a welding robot. At least one displacement sensor is positioned with respect to one of the welding equipment and the check station. The robot moves the horn and anvil via an arm to the check station, when a threshold condition is met, i.e., a predetermined amount of time has elapsed or a predetermined number of welds have been completed. The robot moves the horn and anvil to the check station, activates the at least one displacement sensor, at the check station, and determines a status condition of the welding equipment by processing the received signals. The status condition may be one of the alignment of the vibration welding equipment and the wear or degradation of the vibration welding equipment.
