  • Patent number: 11590616
    Abstract: An underactuated joining system for a moving assembly line includes a robot with actuated joints, an articulated compliance mechanism, and a controller. An end-effector of the mechanism is connected to linkages and to a joining tool, unactuated joints interconnect the linkages, and position sensors measure joint positions of the unactuated joints. In response to the joint positions, a controller regulates a position of the actuated joints to cause the compliance mechanism to compliantly follow the assembly line. This occurs while the tool remains engaged with a workpiece being transported along the assembly line. A method includes engaging the tool with the workpiece as the workpiece is transported by the assembly line, measuring joint positions of the unactuated joints using position sensors, and controlling a position of the active joints to cause the compliance mechanism to compliantly follow the workpiece along the assembly line.

  • Patent number: 11298776
    Abstract: A friction welding method comprises causing an end surface of a first workpiece and an end surface of a second workpiece to engage in relative rotation while the end surfaces are in mutual contact as a compressive load is applied thereto so as to generate heat due to friction at a joint interface between the workpieces, thereafter stopping the relative rotation of the workpieces, and then applying an upset process pressure to the workpieces. When the workpiece end surfaces are brought into mutual contact, a compressive load employed is less than a lower threshold of a bend-producing compressive load domain within which bending of the first workpiece and/or the second workpiece would occur but the compressive load and the relative rotational speed between the workpieces are such as will cause the heat due to friction to be capable of causing plastic deformation at workpiece end surface(s).

The use of a large cold source in combination with thermosensor pad of a particular construction provide a fluid flow analyzer with the ability to detect very low levels of CSF flow. In addition, a method for adjusting thermal dilution readings to compensate for varying shunt catheter depth is shown and for determining a steady state of the thermal dilution readings. The thermosensor pad is conformable to a patient's skin contour thereby making the apparatus and method less sensitive to ambient temperature errors and, as a result, more accurate in assessing CSF flow. Furthermore, a software error check is provided for identifying poor sensor-to-skin contact for alerting an operator to re-apply the thermosensor pad to correct, as well as a post-test check to determine if temperature data is reasonable before determining flow status or flow rate.

    Abstract: The present disclosure related to a flexible electronic substrate assembly and a method and system of processing solder paste onto an electrical substrate. The assembly includes a flexible substrate having a solderable medium provided along the flexible substrate. A pattern of solder paste may be cured to a portion of the solderable medium. The solderable medium may be a generally continuous construction or a patterned construction relative to the flexible substrate. The substrate may be unwound from a roll of substrate material before solder paste is deposited thereon. The flexible electric substrate assembly may be formed though a roll to roll process. Infrared heat may be applied to the substrate with the solder paste deposit as the substrate is traveling along the process direction to reflow the solder paste as the substrate is traveling along the process direction at a high rate of speed.

  • Patent number: 10032743
    Abstract: A semiconductor module is produced by providing a circuit carrier having a metallization, an electrically conductive wire and a bonding device. With the aid of the bonding device, a bonding connection is produced between the metallization and a first section of the wire. A separating location and a second section of the wire, the second section being spaced apart from the separating location, are defined on the wire. The wire is reshaped in the second section. Before or after reshaping, the wire is severed at the separating location, such that a terminal conductor of the semiconductor module is formed from a part of the wire. The terminal conductor is bonded to the metallization and having a free end at the separating location.

  • Patent number: 10010928
    Abstract: A device for direct screwing, in particular flow hole screwing, or friction welding includes a guide element extending in an axial direction and being formed in particular as a guide pipe. A driveshaft is movable in the axial direction, disposed within the guide element and driven by a rotary drive. A feed drive is disposed and constructed to generate a feed movement and feed force transmitted to the driveshaft, which is achieved by a feed unit. During the process, depending on a process parameter, a switchover is made from a high feed force to a reduced feed force (flow hole screwing) or to a higher feed force (friction welding). In order to enable the most compact and weight-saving embodiment possible, the feed unit is disposed coaxially to the driveshaft within the guide element and transmits the feed force to the driveshaft in the axial direction and centrally.

  • Patent number: 9986649
    Abstract: An apparatus for increasing solder hole-fill in a printed circuit board assembly (PCBA) are provided in the illustrative embodiments. In the PCBA comprising a Printed Circuit Board (PCB) and the device, a pin of a device is caused to move in a first direction, the pin occupying a hole in the PCB, the hole being filled to a first distance by a solder material. By causing the pin to move, the solder material is drawn into the hole up to a second distance that is greater than the first distance. The pin is allowed to move in a second direction, to return the pin to an initial position in the hole. Allowing the pin to move in the second direction keeps the solder material at a third distance, wherein the third distance is greater than the first distance in the hole.

  • Patent number: 9881893
    Abstract: The present disclosure provides an apparatus for removing a chip, including: a loading station; a heating head arranged to soften an anisotropic conductive film on a substrate of a display panel for fixing the chip; a base table arranged on the loading station and arranged to support the display panel; and a base seat arranged on the loading station and arranged to support the heating head, wherein the heating head is rotatably mounted onto the base seat and the heating head has a rotation axis perpendicular to a surface of the loading station facing towards the base table. With the above apparatus, the face of the heating head facing towards the chip contacts with the face of the chip facing towards the heating head more sufficiently. The force to which the portion of the chip is subject is reduced and the force applied to the chip becomes more uniform.

  • Patent number: 9839973
    Abstract: A friction stir spot welding apparatus according to the present invention includes: a rotary tool; and a perpendicular-to-plane detector, which detects whether or not the rotary tool is positioned to be in a perpendicular-to-plane state relative to a joining target portion of workpieces. The perpendicular-to-plane detector measures distances to at least three measurement positions set around the joining target portion by means of, for example, position sensors. The measurement positions are set to be positioned at the vertices of a polygon on a reference plane to which forward and backward movement directions of the rotary tool are normal. The perpendicular-to-plane detector detects that the rotary tool is positioned to be in the perpendicular-to-plane state relative to the joining target portion of the workpieces if all the distances to the measurement positions are equal to each other.

  • Patent number: 9375913
    Abstract: A screen printer in which a photoelectric sensor and squeegees are fixed to a slider, when outward movement printing in which solder on a screen is rolled by an outward movement of the right squeegee is completed, the right squeegee is separated from a state of contacting a right end of a solder roll and a squeegee position pl at that time is input, and, subsequently, the slider is returned until the photoelectric sensor detects a left end of the solder roll and a squeegee position p2 at this time is input. An amount (a solder roll width) of solder remaining on the screen is calculated by subtracting a movement amount from the squeegee position p1 to the squeegee position p2 from a distance from the right squeegee to an optical axis position of the photoelectric sensor on the screen.
