  • the compression plate 804 may be configured to remain magnetically coupled with the support plate 802 during a sequence of manufacturing processes that involve the exchanging of other compression plates (as will be illustrated in FIGs. 9 and 10 ).
  • the compression plate 804 may be functional to maintain the article 808 within the manufacturing feature 806 while other compression plates are exchanged between different manufacturing processes.
  • the compression plate 804 is shaped to also universally coordinate with subsequently interchanged compression plates, in an exemplary aspect. This shaping may further aid in the alignment of a subsequently positioned compression plate.
  • the edge or portion to which a subsequently positioned compression plate is proximate may be shaped, such as a male/female relationship to aid in the alignment of the subsequently positioned compression plate.
  • FIG. 8 While a specific configuration of various components are depicted in FIG. 8 for illustrative purposes, any combination of features having any number or configuration of features/components may be implemented within the scope of the aspects presented herein.
  • FIG. 9 depicts a second configuration 900 of the support plate 802 having a second compression plate 902 magnetically coupled thereto, in accordance with aspects of the present invention.
  • the second compression plate 902 is coupled with the support plate 802 solely by a series of complimentary magnetic members, such as a magnetic member 912, that magnetically attract to a counterpart magnetic member of the support plate 802, such as the magnetic member 812 of FIG. 8 .
  • the second compression plate 902 self-aligns with the support plate 802 in this example by leveraging the magnetic configuration and geometric configuration of the magnetic member 912 (and magnetic member 812 of FIG. 8 ). Therefore, a human (or a machine) needs only to position the compression plate 902 in an approximately desired position relative to the support plate 802 in order for the magnetic member to self-align and magnetically secure the second compression plate 902 with the support plate 802.
  • the second compression plate 902 is configured such that the magnetic member 912 is positioned in a location on the second compression plate 902 such that when the magnetic member 912 is attracted with the magnetic member 812 of FIG. 8 , a manufacturing void through which the article 808 is accessible is positioned in an appropriate location on the article 808.
  • the manufacturing void which provides access to the article for a manufacturing process through a plate, such as a compression plate, may be changed by switching out the compression plates magnetically coupled with the support plate, in an exemplary aspect.
  • FIG. 10 depicts a third configuration 1000 with the support plate 802 magnetically coupled with a third compression plate 1002, in accordance with aspects hereof.
  • the third compression plate 1002 is configured with magnetic members arranged to coordinate with complimentary magnetic members secured in the support plate 802.
  • the magnetic member of the third compression plate 1002 are further arranged such that a manufacturing void is positioned in a desired location relative to the article 808 to facilitate an appropriate manufacturing process on the article 808.
  • a magnetic member 1012 is configured to self-align with a complimentary magnetic member, such as the magnetic member 812 of FIG. 8 .
  • the first compression plate 804 remains magnetically coupled with the support plate 802 when both the second compression plate 902 and the third compression plate 1002 are magnetically coupled with the support plate 802. It is contemplated that the first compression plate 804 is effective for maintaining the article 808 in a desired position relative to the support plate 802 during the transition from the second compression plate 902 to the third compression plate 1002.
  • FIGs. 8-10 are illustrative in nature and not intended to be limiting. It is contemplated that any number of magnetic members may be positioned in an arrangement and having any characteristic that achieves aspects provided herein. Further, it is contemplated that the manufacturing voids through the compression plate which the article is accessible may be of any size, shape, and location that is suitable for performing a desired manufacturing process. The size, shape, and features of the support plate may be of any size, shape and combination of features that facilitate aspects provided herein.
  • FIG. 11 depicts a block diagram illustrating a method 1100 for using a magnetic self-aligning fixture in a manufacturing process, in accordance with aspects hereof.
  • a step of positioning an article in a manufacturing feature of a support plate is represented.
  • the support plate is comprised of one or more magnetic members, such as a convex magnetic member.
  • the magnetic member having a particular magnetic field configuration that facilitates self-aligning of a complimentary magnetic member that is secured within a compression plate to be secured thereto the support plate.
  • a step of magnetically securing a first compression plate to the support plate is represented.
  • the support plate and the first compression plate secure the article there between.
  • the first compression plate has a magnetic member that is configured to self-align and attract to the magnetic member of the support plate. Further, the magnetic member is positioned within the first compression plate such that a manufacturing void of the first compression plate is positioned at a location of the article that is intended for a manufacturing operation to be performed.
  • a step of performing a manufacturing process on the article as secured by the support plate and the first compression plate is represented.
  • the manufacturing process may be any process, such as sewing, embroidering, painting, spraying, printing, welding, bonding, tacking, cutting, punching, embossing, and the like. This manufacturing process may leverage an opening in the compression plate that allows a manufacturing apparatus (or human) to access the desired portion of the article for performing the manufacturing process.
  • a step of removing the first compression plate from the support plate is represented.
  • the first compression plate is physically separated from the support plate by a sufficient distance to overcome the magnetic attraction between the complimentary magnetic members. It is contemplated that the article remains positioned in the manufacturing feature of the support plate following the removal of the first compression plate.
  • a step of magnetically securing a second compression plate to the support plate is represented.
  • the second compression plate is comprised of one or more magnetic members that correspond with and compliment one or more magnetic members of the support plate such that the second compression plate self-aligns and magnetically couples with the support plate.
  • the position of the magnetic members in the second compression plate are arranged such that a manufacturing void is positioned at a desired location on the article as maintained between the support plate and the compression plate. It is contemplated that additional portions of the article (e.g., additional piece of upper material) may be placed on the article prior to securing the second compression plate to the support plate.
  • the second article material may be process in combination (or independently) of the article positioned in block 1102.
  • a step of performing a second manufacturing process on the article is represented.
  • the second manufacturing process may be the same as performed at block 1106; however, it may be performed at a different location or on a different material combination.
  • the article is maintained in a common support plate having defined magnetic member configurations and multiple operations are performed on the article using different compression plates.
  • the method 1100 is exemplary in nature and not intended to be limited as to the scope provided herein. For example, one or more steps may be omitted or rearranged in ordering. Further, it is contemplated that additional steps may be inserted in exemplary aspect.
