Wire Straightening Patents (Class 140/147)
  • Publication number: 20040261886
    Abstract: The present invention refers to a method and a mechanism for convergence of a multitude of wires (1-4) wire rods, tubes, or other material of prismatic cross section to one particular line (00), where the material may be cut and stored or may be cut and bent or may be cut and welded or may be cut and processed in another way. The method depends on the elastic properties of metals, which can be temporarily deformed when under stress, and are restored to their original shape when the stress load is removed, as long as the stressing of the metal remains in the elastic region. Hence, during the convergence of wires, there is a minimum distance between the feeding-straightening (6-9) units and the point of convergence to a common line, which is defined by the material with the weakest elastic properties and by the locations of the feeding lines. The method can be applied to feeding line, which are parallel with each other or not, and for feeding lines, which lie or not on the same plane.

  • Patent number: 6615482
    Abstract: An amorphous magnetic core is produced by wrapping cut strips of amorphous metal about a mandrel to form a distributed gap core. The cut strips are secured to the mandrel during assembly by wrapping the strips with amorphous metal ribbons that have been weakened in predetermined areas but not fully parted. After the core has been built to its desired size, the weakened ribbons are completely parted. This method of making an amorphous magnetic core produces a tightly wound distributed gap core without the need for a belt winder or specialized strip holding devices.

  • Patent number: 5319847
    Abstract: A method and apparatus for conditioning the leads of integrated circuit devices having a plurality of sequential stations. The flat device packages have rows of J-shaped leads along the edges. Individual devices are picked up at an input station and moved to a precising nest where the device is accurately located. The device is moved, preferably by a vacuum chuck transport mechanism, to a first conditioning station where a precising bar adjusts lead spread, then a needle is inserted through the row of leads to adjust lead standoff. A coining die reforms the "J" configuration and establishes a precisely uniform seating plane for all leads. A combing blade arrangement then establishes the lead spacing and lead sweep. After leads along two opposite sides of the device are conditioned, the device is moved to a second conditioning station (if required) where these operations are repeated on the other two sides of the device.

  • Patent number: 5283946
    Abstract: The excise and lead form of TAB leads bonded to an integrated circuit chip. Leads extending beyond a sidewall are clamped between a first clamp and a form anvil at a first portion spaced from the chip. The leads are also clamped between an excise/form tool and a second clamp at a second portion spaced further from the chip than the first portion. An excise blade cuts the leads outside the second portion. Then the excise/form tool, second clamp and excise blade move downwards in a curved path toward the chip to form a first lead corner against the form anvil and a second lead corner against the excise/form tool without splaying or galling the leads.

  • Patent number: 5161584
    Abstract: A wire straightener (10) for accommodating different size wires (12) includes first and second wire-bending stations (15a) and (15b) located on opposite sides of a central member (14). Each of the wire-bending stations (15a,15b) includes a pair of opposed, complementary contours (56,60), the individual length of which, and the spacing relative to the other contour, may be adjusted. Extending between the contours (56,60) along their respective lengths is a wire-receiving passage (62) which communicates with the wire-receiving passage in the other station. The opposed, complementary contours (56,60) of each wire-bending station are orthogonal to those of the other station so that as the wire is forced through the wire-receiving passage (62), the wire is bent in each of two orthogonal planes, causing it to be straightened upon exiting the second station.

  • Patent number: 5123457
    Abstract: A simple, manual tool for re-aligning lead pins on a pin grid array (PGA) integrated circuit (IC) chip or the like. The tool has a series of removable, parallel bending plates mounted between a top and a base. The bending plates fit between the lead pins to be re-aligned. Re-alignment is accomplished by displacing the top relative to the base (which is stationary), which causes the bending plates to swivel from the base and impinge upon the lead pins at the upper ends of the bending plates. Permanent re-alignment is achieved by bending the lead pins past their elastic limit to a desired point. The top remains parallel to the base at all times. Maximum displacement of the bending plates is limited by an outer skirt when it contacts the base. Four springs bias the tool toward the neutral position. After the lead pins are re-aligned in one direction, the PGA is removed, rotated 90 degrees, and the re-inserted, whereupon the re-alignment routine is performed again to complete the re-alignment process.
