20110284169 | ULTRASONIC WELDING ASSEMBLY AND METHOD OF ATTACHING AN ANVIL TO A BRACKET OF THE ASSEMBLY - An ultrasonic welding assembly having an ultrasonic horn and an anvil having first, second, and third plate portions is provided. The third plate portion is coupled between the first and second plate portions. The first plate portion has a first knurled region on a first side disposed proximate to the ultrasonic horn, and the second plate portion has a second knurled region on a second side. The third plate portion has a first aperture extending therethrough. The assembly includes a bracket that receives the second side of the anvil for holding the anvil thereon. The bracket has a second aperture that aligns with the first aperture, such that a coupling member extending through the first and second apertures removably couples the anvil to the bracket. | 11-24-2011 |
20110300438 | BATTERY MODULE AND METHODS FOR BONDING A CELL TERMINAL OF A BATTERY TO AN INTERCONNECT MEMBER - A battery module and methods for bonding a cell terminal of a battery to an interconnect member are provided. The battery module includes a battery cell having a cell terminal, and an exothermal reactive layer having first and second sides. The first side is disposed adjacent to the cell terminal. The module further includes an interconnect member disposed adjacent to the second side of the exothermal reactive layer. The exothermal reactive layer is ignited to form a bonding joint between the interconnect member and the cell terminal in response to a laser beam contacting at least a portion of the exothermal reactive layer. | 12-08-2011 |
20120158168 | SYSTEM AND METHOD FOR DETERMINING WHETHER AN ULTRASONIC HORN IS ALIGNED WITH AN ANVIL - A system and a method for determining whether an ultrasonic horn is aligned with an anvil of an ultrasonic welding system are provided. The first and second accelerometer sensors generate first and second signals indicative of first and second accelerations of first and second positions on a bracket coupled to the anvil when the ultrasonic horn is vibrating and contacting the anvil. The system further includes a microprocessor that receives the first and second signals. The microprocessor determines a difference between an amplitude of the first signal at a first time and an amplitude of the second signal at the first time. The microprocessor stores a first identifier value in a memory device indicating that the ultrasonic horn is aligned with the anvil if the difference between the amplitude of the first signal and the amplitude of the second signal is less than or equal to a threshold value. | 06-21-2012 |

20130029204 | BATTERY MODULES HAVING INTERCONNECT MEMBERS WITH VIBRATION DAMPENING PORTIONS - Battery modules having interconnect members are provided. An interconnect member includes a first plate portion having a first thickness. The interconnect member further includes a second plate portion having a second thickness equal to the first thickness. The second plate portion extends generally parallel to the first plate portion. The interconnect member further includes a first vibration dampening portion coupled to the first and second plate portions. The first vibration dampening portion has a third thickness greater than the first thickness, such that vibrations induced on the first plate portion are attenuated when a portion of the vibrations pass through the first vibration dampening portion to the second plate portion. | 01-31-2013 |
20130042959 | ULTRASONIC WELDING MACHINE AND METHOD OF ALIGNING AN ULTRASONIC WELDING HORN RELATIVE TO AN ANVIL - An ultrasonic welding machine and method are provided. The machine includes an ultrasonic welding horn operably coupled to a housing. The machine further includes an anvil operably coupled to the housing. The machine further includes a removable collar assembly that is coupled around a portion of an outer surface of the ultrasonic welding horn. The removable collar assembly has at least first and second set screws that contact the housing such that when at least one of the first and second set screws are moved inwardly toward the housing, the removable collar assembly rotates the ultrasonic welding horn to align the ultrasonic welding horn relative to the anvil. | 02-21-2013 |
20130052511 | INTERCONNECTION ASSEMBLIES AND METHODS FOR FORMING THE INTERCONNECTION ASSEMBLIES IN A BATTERY MODULE - Interconnection assemblies and methods are provided. An interconnection assembly includes a first cell tab constructed of a first metal, and a second cell tab disposed against the first cell tab. The second cell tab is constructed of a second metal having a hardness greater than the first metal. The assembly further includes an interconnect member disposed against the second cell tab. The assembly further includes a weld assisting layer disposed against the first cell tab such that the first and second cell tabs are disposed between the weld assisting layer and the interconnect member. | 02-28-2013 |
20150017508 | INTERCONNECTION ASSEMBLIES AND METHODS FOR FORMING THE INTERCONNECTION ASSEMBLIES IN A BATTERY MODULE - Interconnection assemblies and methods are provided. An interconnection assembly includes a first cell tab constructed of a first metal, and a second cell tab disposed against the first cell tab. The second cell tab is constructed of a second metal having a hardness greater than the first metal. The assembly further includes an interconnect member disposed against the second cell tab. The assembly further includes a weld assisting layer disposed against the first cell tab such that the first and second cell tabs are disposed between the weld assisting layer and the interconnect member. | 01-15-2015 |

20120153006 | ULTRASONIC WELDING SYSTEM AND METHOD FOR FORMING A WELD JOINT - An ultrasonic welding system and a method are provided. The system includes an ultrasonic welding device and a controller that generates control signals for inducing the device to form a first weld joint. The system further includes a power adjusting unit having a desired output power level curve indicating desired power levels over time for obtaining a desired weld joint. The unit receives data from the controller indicating power levels when forming the first weld joint. The unit compares a power level output by the controller at a first time with an associated power level of the curve at the first time, and induces the controller to increase the power level at a second time if the power level output by the controller at the first time is less than the associated power level of the curve at the first time. | 06-21-2012 |
20120180929 | ULTRASONIC WELDING SYSTEM AND METHOD FOR FORMING A WELD JOINT UTILIZING THE ULTRASONIC WELDING SYSTEM - An ultrasonic welding system and a method are provided. The system includes an ultrasonic welding device having an ultrasonic welding horn. The system further includes a controller generating control signals for inducing the welding device to form a first weld joint. The system further includes a power adjusting unit that induces the ultrasonic welding controller to increase a power level output by the ultrasonic welding controller to the ultrasonic welding device if a first displacement of the welding horn is less than the desired displacement during partial completion of forming the first weld joint, such that upon completion of the first weld joint an ending position of the ultrasonic welding horn is at a desired ending position. | 07-19-2012 |
