Reconfigurable manufacturing system and method for manufacturing composite laminates
A manufacturing system includes a first mandrel, a second mandrel, and laminate securing mechanisms. The first mandrel has a first mandrel surface and a first mandrel surface edge. The second mandrel has a second mandrel surface and a second mandrel surface edge, and is positionable in a closed position in which the first mandrel surface edge and the second mandrel surface edge are in contact to form a continuous mandrel surface collectively defined by the first mandrel surface and the second mandrel surface. The second mandrel translates to an open position defining a gap between the first mandrel surface edge and the second mandrel surface edge for receiving a forming die. The laminate securing mechanisms secure the composite laminate on at least one of the first mandrel and the second mandrel during trimming and/or forming of the composite laminate.
METHOD AND APPARATUS FOR THERMOFORMING AN ARTICLE
A method for thermoforming an article includes extruding a sheet of material, conditioning the sheet with a roller, thermoforming the sheet to provide a web, and cutting the web to provide the article.
Continuous fabrication for composite preforms
Systems and methods are provided for fabricating preforms for composite parts. One embodiment is a method of creating a preform. The method includes conveying a web of fiber reinforced composite material in a process direction, disposing fiber reinforced composite material atop the web, conveying the web and the tow in the process direction to a cutting tool, and cutting out a preform comprising a combination of the tow and the web.
Thermoforming machine
A thermoforming machine for manufacturing articles from a heated thermoplastic film includes a molding station, an extraction device, a hole punch; and a stacking station. The hole punch includes a pivotable lower punching tool which receives punched-out articles from the extraction device while being pivoted into a tilted position facing the extraction device and which pivots into a vertical 0 position to face an upper punching tool for punching operation.
Tube sealer
A device for sealing sample tubes comprises a tool assembly configured to interface with a rack (10) holding a plurality of sample storage tubes (20), the tool assembly holding a plurality of punches (322) and a die plate (324) including a plurality of cutting holes, with each of the plurality of cutting holes accepting one of the plurality of punches (322). The tool assembly receives a foil sheet (131) between the punches (322) and the die plate (324). The device includes an actuator enabling linear movement of the tool assembly. Linear movement of the tool assembly towards the rack (10) engages the die plate (324) against the rack (10) and punches the punches (322) through the cutting holes of the die plate (324) to punch a plurality of sealing sections from the foil sheet (131) and to press and seal each of the sealing sections against a top end of each of the plurality of sample storage tubes (20) in the rack (10).
TECHNIQUES FOR OVERMOLDING THERMOPLASTICS ONTO A SPRAY PRIMED POLYMER SUBSTRATE
Techniques for overmolding thermoplastics onto a spray primed polymer substrate. A thin layer of primer may be sprayed directly over a pre-formed polymer material. Then, a thermoplastic is injection molded directly over the primer layer. In one embodiment, a carbon fiber-reinforced polymer (CFRP) fabric is thermal compression molded into a NED device housing shell. Selected portions of the NED device housing shell may be mechanically abraded and then sprayed with a solvent-based polyolefin primer. Once the primer layer has cured, a thermoplastic material may then be overmolded directly over the primer layerwithout any additional adhesive layer(s) between the primer layer and the thermoplastic material.
Soft robotic actuators and methods of manufacturing the same
Exemplary embodiments relate to various improvements in soft robotic actuators, and techniques for manufacturing the improvements. For example, techniques for manufacturing a rigidizing layer for reinforcing a soft robotic actuator is provided. In another embodiment, a soft robotic actuator having integrated sensors is described. A flexible electroadhesive pad for achieving a conformal grip is also described. Still further, exemplary embodiments provide hydraulically-actuated soft robotic grippers, which allows for a reduction in the size of the actuation system and improved underwater operation.
Molded Air Intake System and Method for Internal Combustion Engines
A Molded Air Intake System and Method for Internal Combustion Engines. The method of the present invention permits the single-shot molding of an air intake system, such as by roto-molding. The resultant air intake system has an internal pipe element and an external element, both of which are formed with superior molding tolerances. The internal pipe element is defined by an inner mold form that is insertible and removable from an external mold form. The final molded part defines an outer wall and an inner wall and an MAFS mounting pad having inner and outer apertures formed therethrough.
INSPECTION DEVICE, PTP PACKAGING MACHINE AND CALIBRATION METHOD OF INSPECTION DEVICE
An inspection device includes: an illumination device that irradiates standard and inspection objects with near-infrared light; a spectroscope that disperses reflected light; an imaging device that takes images of first and second optical spectrums of the reflected light dispersed by the spectroscope to obtain standard spectroscopic image data and inspection spectroscopic image data; and a processor. The processor executes a predetermined arithmetic operation with regard to at least one of (i) each pixel row of the standard spectroscopic image data perpendicular to a wavelength dispersion direction and (ii) each pixel column of the standard spectroscopic image data parallel to the wavelength dispersion direction. The processor, based on luminance values of pixels belonging to the pixel row or column, determines a characteristic of the pixel row and grasps a wavelength sensitivity characteristic of the imaging element under the near-infrared light emitted from the illumination device.
Panel-molded electronic assemblies
A method of encapsulating a panel of electronic components such as power converters reduces wasted printed circuit board area. The panel, which may include a plurality of components, may be cut into one or more individual pieces after encapsulation with the mold forming part of the finished product, e.g. providing heat sink fins or a surface mount solderable surface. Interconnection features provided along boundaries of individual circuits are exposed during the singulation process providing electrical connections to the components without wasting valuable PCB surface area. The molds may include various internal features such as registration features accurately locating the circuit board within the mold cavity, interlocking contours for structural integrity of the singulated module, contours to match component shapes and sizes enhancing heat removal from internal components and reducing the required volume of encapsulant, clearance channels providing safety agency spacing and setbacks for the interconnects. Wide cuts may be made in the molds after encapsulation reducing thermal stresses and reducing the thickness of material to be cut during subsequent singulation. External mold features can include various fin configurations for heat sinks, flat surfaces for surface mounting or soldering, etc. Blank mold panels may be machined to provide some or all of the above features in an on-demand manufacturing system. Connection adapters may be provided to use the modules in vertical or horizontal mounting positions in connector, through-hole, surface-mount solder variations. The interconnects may be plated to provide a connectorized module that may be inserted into a mating connector.
