Measuring laser light transmissivity in a to-be-welded region of a work piece

Methods for measuring laser light transmissivity of a specific position in a work piece prior to the work piece undergoing laser welding at the specific position with a laser beam having a specific welding wavelength. To obtain a baseline measurement reading, a laser light source projects a laser beam at the welding wavelength directly into a detector. Thereafter, the work piece becomes suspended between the laser light source and detector whereby an output of the detector now corresponds to a work piece measurement reading. Differences between the two readings reveal whether the work piece will yield a satisfactory weld at the specific position when later welded by a laser beam at the welding wavelength. Preferred work pieces include inkjet printhead lids and bodies.

Optical Feedback Signal Compensation For Background Infrared Radiation In A Laser Chamber

Plastic parts are welded in a laser welding system. An infrared laser source in a laser chamber is controlled by a controller using closed-loop feedback control with a corrected feedback signal that is compensated for background infrared radiation in the laser chamber. Prior to the infrared laser source being turned on, the controller senses with the optical sensor an intensity of background infrared radiation in the laser chamber. Once the laser is on, the controller senses with the optical sensor an intensity of infrared laser radiation in the laser chamber. The controller calculates the corrected feedback signal by subtracting the intensity of the background infrared radiation sensed when the infrared laser source was off from the intensity of the infrared laser radiation sensed when the infrared laser source is on.

Controlled translation method of affixing a termination to a multi-stranded tensile member

A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with one or more internal cavities. Each cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. Once the potting compound in at least a portion of the cavity has transitioned sufficiently to hold the filaments at a desired level, tension is placed on the tensile member and a small linear displacement may be imposed on the tensile member. This linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing. The invention can be applied to single fittings having multiple cavities ...

A rubber sheet member joining device , comprising:a pair of gripping parts for gripping, respectively, ranges in proximity to end surfaces of rubber sheet members to be joined, the rubber sheet members being unvulcanized;a drive unit that moves at least one of the pair of gripping parts in a direction approaching and separating from each other; anda control unit for controlling operation of the pair of gripping parts and operation of the drive unit,the rubber sheet member joining device being configured such that:at least one opposing surface of the pair of gripping parts comprises a contact member with a contact surface projecting toward an other opposing surface of the pair of gripping parts;when the pair of gripping parts are in close proximity to each other, the contact member is in a state of being sandwiched between the opposing surfaces, and movement of the pair of gripping parts in proximity to each other is stopped;the ranges in proximity to the rubber sheet members are gripped, respectively, in a state in which the end surfaces project from the one opposing surface ...

Sonotrode and Anvil Energy Director Grids for Narrow/Complex Ultrasonic Welds of Improved Durability

A specially designed sonotrode and anvil are adapted to be used in combination for ultrasonic welding of work pieces, to produce a narrower weld region, but one exhibiting greater durability, thereby permitting use of less packaging material. The contact surfaces comprise a surface of the anvil having a plurality of energy directors, where the plurality of energy directors are arranged into a three-dimensional grid pattern to be capable of distributed vibration-transmissive contact. The energy directors may comprise a series of plateau surfaces being regularly spaced apart from each other in a first direction, and in a second direction that is orthogonal to the first direction, to form the grid pattern. The rectangular-shaped plateaus may be spaced apart by valleys. Engagement of the energy directors of the anvil with the corresponding surface of the sonotrode may cause minor elastic deformation of work pieces positioned therebetween prior to ultrasonic welding. 1. A horn and anvil combination for a form-fill-seal machine , for use in ultrasonic welding of thin film work pieces , to provide improved weld integrity in packaging liquids with reduced weld widths for reduced per-package material usage: 'a plurality of energy directors spaced in a first direction to form a pattern, each of said, plurality of energy directors comprising a shaped plateau surface with each side of said shaped plateau surfaces configured to transition into an angled side surface; with each of said angled side surfaces of each said plateau surface connected with another side surface of an adjacent plateau surface to form a trough therebetween, except at an outer periphery of said horn;', 'said horn comprising 'a plurality of energy directors spaced in a first direction to form a pattern, each of said plurality of energy directors comprising a shaped plateau surface with each side of said shaped plateau surface configured to transition into an angled side surface; with each of said angled side ...

Welding apparatus having a safety feature

Welding apparatus ( 10; 30 ) having a safety feature comprising: two electrodes ( 11, 12; 21, 22 ), whereof at least one of said two electrodes is movably arranged in relation to the other electrode. The electrodes are in non-contact with each other and define a gap ( 13 ) in which an object ( 14 ) provided with an electrically non-conductive surface to be sealed may be inserted. The welding apparatus comprises an actuator ( 15; 25 ) configured to move at least one electrode when activated to squeeze the object, a detector ( 16; 26 ) configured to determine a clamping force when the inserted object ( 14 ) is squeezed between the electrodes, a distance sensor ( 17; 23 ) configured to measure the distance between the electrodes. There is also a conductance sensor ( 24 ) configured to measure the conductivity of an object located between the electrodes ( 11, 12; 21,22 ) when the object ( 14 ) is squeezed, and optionally a position sensor ( 19 b ) configured to detect the position of the object ( 14 ) inserted between the electrodes. The welding apparatus further comprises a processor configured to process the input from at least one of the detector ( 16; 26 ), the distance sensor ( 17; 23 ) and the conductance sensor ( 24 ) to provide an output that indicates if there is a blood bag tube inserted between electrodes, or if it is a foreign object.
