[0019] Several embodiments are described and illustrated in this document to provide a general understanding of the structure, function, and use of the articles and methods disclosed. The various embodiments described and illustrated in this descriptive report are non-limiting and non-exhaustive. Thus, an invention is not limited by the description of the various non-limiting and non-exhaustive embodiments disclosed in this descriptive report. Instead, the invention is defined solely by the claims. The features and characteristics illustrated and / or described in connection with various embodiments may be combined with the features and characteristics of other embodiments. Such modifications and variations shall be included within the scope of this descriptive report. Therefore, the claims may be modified to recite any features or characteristics expressly or intrinsically described or otherwise expressly or intrinsically supported by this descriptive report.Furthermore, a. Petition 870260055350, dated 08 / 06 / 2026, p. 7 / 58 4 / 19 The applicant reserves the right to modify the claims so as to affirmatively deny features or characteristics that may be present in the prior art. The various embodiments disclosed and described in this descriptive report may include, consist of, or consist essentially of the features and characteristics described herein in various ways.

[0020] Resistance Spot Rivet (RSR™) joining technology is a new resistance joining technology that can enable the joining of a variety of parts made from various material combinations. RSR™ joining technology uses rivets (e.g., metal rivets) of various geometries and materials to offer a selection of solutions to match each joining scenario. Rivets can be applied to the joint using a modified resistance spot welding gun (e.g., RDS-enabled welding gun). The welding gun can be paired with a robotic manipulator and / or a pedestal welder and integrated into an auxiliary component system. Each joint made using RSR™ joining technology typically consumes one rivet.

[0021] When a rivet is required for joining parts, a rivet dispensing system can transport rivets to a location near the rivet installation site on the assembly being joined using a channel (e.g., feed rail) of a rivet distribution system. The channel can be configured (e.g., dimensioned and shaped) to allow rivets to pass from one end of the channel to the other in a series arrangement and in a pre-selected orientation so that the rivets can engage with a rivet holder of a resistance spot rivet welding apparatus. For example, the channel may comprise a generally T-shaped cross-section suitable for receiving and transporting rivets having a generally T-shaped profile. Petition 870260055350, dated 08 / 06 / 2026, page 8 / 58 5 / 19 For example, an upper region of the T-shaped cross-section of a channel can be dimensioned to accommodate a rivet head portion, and a cross-sectional region of the T-shaped cross-section of the channel can be dimensioned to accommodate a rivet shank.

[0022] Previous rivets 100a-b have a shape with a head portion 102 comprising a narrow leading edge 106 at an angle that can be easily formed in a cold manifold, but may jam in the channel 130 due to ripple (e.g., overlapping of the head portions 102 in the upper region of the channel), as illustrated in Figure 1. For example, rivet 100b may contact channel 130 at points 122 and 120, where one side 102a of the head portion 102 of rivet 100b may lift up, so that the leading edge 106 (when rivets 100a-b move from right to left in the drawing) of rivet 100b is on top of the head portion 102 of rivet 100a, thus causing a ripple effect 124 (e.g., welding of rivets) which can prevent rivets 100a-b from moving further within channel 130.

[0023] Therefore, an anti-slip rivet is provided according to the present disclosure which may comprise a blind outer edge, which may be more difficult to manufacture (since it, unlike the outer edge of conventional rivets, may be significantly more difficult to form in a cold manifold), but wherein the blind outer edge may inhibit or prevent the type of point-to-point contact on a chamfered edge of rivets which might otherwise result in jamming forces that could lead to jamming in the channels. Thus, anti-slip rivets according to the present disclosure may resist slippage and may be fed through the rivet feed channel in a series arrangement and in a pre-selected orientation so that they may engage from Petition 870260055350, dated 08 / 06 / 2026, page 9 / 58 6 / 19 consistent and predictable form with a rivet holder of a resistance spot rivet welding apparatus. The rivets according to the present disclosure can be fed automatically by a cartridge or a blow feeder without, or with less occurrence of, jamming or slippage.

[0024] According to aspects of the present disclosure, anti-slip rivets 200a-b comprising a head portion 202 including a cylindrical or shallow tapered outer edge 206 that may not cause slippage in the rivet distribution system (RDS) are provided in this document and illustrated in Figures 2, 3A-C, 4A-4C and 5A-5B. For example, rivet 200b may contact the channel 230 at points 222 and 220, where one side 202a of the head portion 202 of rivet 200b may lift slightly. However, due to the shape and configuration of the edge 206, the slippage effect may be minimized or prevented, so that rivets 200a-b may move through the channel 230 without jamming or slippage.

[0025] With reference to Figures 3A-3C, an embodiment of an anti-slip rivet 300 is provided according to the present disclosure. The anti-slip rivet 300 can be configured to fasten layers of an assembly together using a resistance spot rivet welding process. The anti-slip rivet 300 comprises a head portion 302 and a shank 304 extending from the head portion 302 along a longitudinal axis, Ai, of the anti-slip rivet 300. The head portion 302 can be configured for contact by an electrode of a resistance spot rivet welding system. For example, the head portion 302 can extend around a periphery of the shank 304 and can comprise, for example, an annular shape. In several non-limiting embodiments, a cavity 322 may extend through the head portion 302 and at least partially into the stem 304. The cavity Petition 870260055350, dated 08 / 06 / 2026, page 10 / 58 7 / 19 322 can be configured to facilitate contact between the 300 anti-slip rivet and an electrode of the resistance sport rivet welding system. In certain non-limiting applications, the 322 cavity may be bowl-shaped.

[0026] The head portion 302 of the rivet 300 may comprise an outer edge 306. The outer edge 306 extends away from the shank 304 and defines an annular cavity 326. A lower edge 314 of the head portion 302 may be configured to contact a layer of an assembly after installation using a resistance spot rivet welding process. For example, the lower edge 314 of the head portion 302 may be configured to engage / contact a layer of the assembly (e.g., apply a holding force) and, minimally if applicable, penetrate through the engaged / contacted layer, while the shank 304 may be configured to pierce and / or fuse through the engaged / contacted layer and / or a different layer of the assembly during a resistance spot rivet welding process. Additionally, the 304 shank of the 300 rivet can be metallurgically bonded to a layer of the assembly after installation.

[0027] The head portion 302 may extend for a distance, di, along the longitudinal axis, Ai, of the anti-slip rivet 300. In certain non-limiting embodiments, the distance, di, may be at least 0.5 mm, such as, for example, at least 1 mm, at least 1.5 mm, at least 2 mm or at least 3 mm. In several non-limiting embodiments, the distance, di, may not exceed 10 mm, such as, for example, not exceeding 5 mm, not exceeding 4 mm, not exceeding 3 mm, not exceeding 2 mm or not exceeding 1.5 mm. For example, the distance, di, may be in a range from 0.5 mm to 10 mm, such as, for example, 0.5 mm to 5 mm, 2 mm to 4 mm or 1 mm to 2 mm.

[0028] Rod 304 can extend for a distance, d4, along Petition 870260055350, dated 08 / 06 / 2026, p. 11 / 58 8 / 19 of the longitudinal axis, Ai. In certain non-limiting embodiments, the distance d4 may be at least 1 mm, such as, for example, at least 3 mm, at least 4 mm, at least 5 mm or at least 6 mm. In several non-limiting embodiments, the distance d4 may not exceed 30 mm, such as, for example, not exceeding 20 mm, not exceeding 10 mm, not exceeding 9 mm, not exceeding 8 mm or not exceeding 6 mm. For example, the distance d4 may be in a range of 1 mm to 30 mm, such as, for example, 3 mm to 30 mm, 5 mm to 25 mm, 10 mm to 20 mm, 4 mm to 9 mm or 5 mm to 8 mm.

[0029] In certain non-limiting embodiments, the rod 304 may comprise a diameter, ds, not exceeding 10 mm, such as, for example, not exceeding 7 mm, not exceeding 6 mm, not exceeding 5 mm, or not exceeding 4 mm, or not exceeding 3 mm. In several non-limiting embodiments, the rod 304 may comprise a diameter, ds, of at least 1 mm, such as, for example, at least 2 mm, at least 3 mm, at least 4 mm, at least 5 mm, at least 6 mm, or at least 7 mm. For example, the rod 118 may comprise a diameter, ds, in a range from 1 mm to 10 mm, such as, for example, 2 mm to 5 mm, 2 mm to 7 mm, or 3 mm to 6 mm. In certain embodiments, a diameter of the rod 304 may decrease in a direction away from the head portion 302.In certain non-limiting embodiments, the diameter, ds, of the 304 rod may be smaller than the diameter of an electrode in a resistance spot riveting welding system, so that the 304 rod can apply an increased localized force to a layer of an assembly. In several non-limiting embodiments, the 304 rod generally comprises a cylindrical shape.

[0030] The outer edge 306 may comprise a shallow taper, ai, relative to the longitudinal axis, Ai. The outer edge 306 may minimize or prevent rivet slippage in a channel of Petition 870260055350, dated 08 / 06 / 2026, page 12 / 58 9 / 19 rivet distribution. For example, the outer edge 306 may be substantially flat and / or substantially aligned with the longitudinal axis, Ai, of the anti-slip rivet 300.

[0031] In several non-limiting embodiments, the shallow taper, ai, may be less than 15 degrees with respect to the longitudinal axis, Ai, such as, for example, less than 14 degrees, less than 10 degrees, less than 8 degrees, less than 6 degrees, less than 5 degrees, less than 4 degrees or less than 2 degrees, all with respect to the longitudinal axis, Ai. In certain non-limiting embodiments, the shallow taper, ai, may be at least 0 degrees with respect to the longitudinal axis, Ai, such as, for example, at least 1 degree, at least 2 degrees, at least 4 degrees, at least 5 degrees, at least 6 degrees, at least 8 degrees, or at least 10 degrees, all with respect to the longitudinal axis, Ai. For example, the shallow taper, ai, can be in a range of 0 degrees to 15 degrees relative to the longitudinal axis, Ai, such as, for example, 1 degree to 14 degrees, 2 degrees to 14 degrees, 4 degrees to 12 degrees, 5 degrees to 10 degrees, or 6 degrees to 8 degrees, all relative to the longitudinal axis, Ai.

[0032] In several non-limiting embodiments, the shallow taper, ai, may be substantially 0 degrees relative to the longitudinal axis, Ai, and the outer edge 306 may comprise a cylindrical shape. For example, the outer edge 306 may be substantially parallel to the longitudinal axis, Ai. In certain other non-limiting embodiments, the shallow taper, cu, may be in a range of more than 0 degrees to 15 degrees relative to the longitudinal axis, Ai, and may comprise a frustoconical shape. The outer edge 306 may be substantially flat or curved. For example, the outer edge 306 may comprise a cylindrical shape, a frustoconical shape, a concave shape, a convex shape, a stepped shape, or another curved shape.

[0033] The outer edge 306 can extend for a distance, d2, generally in the direction of the longitudinal axis, Ai, of the rivet 300. In several Petition 870260055350, dated 08 / 06 / 2026, page 13 / 58 In certain non-limiting modalities, the distance, d2, may be at least 20 percent of the distance, di, such as, for example, at least 20 percent, at least 30 percent, at least 40 percent, at least 50 percent, at least 60 percent, at least 70 percent, or at least 80 percent of the distance, di. In certain non-limiting modalities, the distance, d2, may not be greater than the distance, di, such as, for example, not greater than 90 percent, not greater than 80 percent, or not greater than 70 percent of the distance, di. For example, the distance, d2, may be in a range of 20 percent to 100 percent of the distance, di, such as, for example, 30 percent to 80 percent, 20 percent to 60 percent, 30 percent to 60 percent, or 30 percent to 40 percent of the distance, di. In certain non-limiting embodiments, the distance, di, may be 0.115 inch (2.9 mm) or greater.For example, the distance, di, can be 0.115 inch (2.9 mm) and the distance, d2, can be 35% of the distance, di.

[0034] The head portion 302 of the anti-slip rivet 300 may comprise a diameter, ds, which is at least 4 mm, such as, for example, at least 5 mm, at least 6 mm, at least 7 mm, at least 10 mm, at least 12 mm, at least 14 mm, at least 15 mm, at least 16 mm, at least 18 mm, at least 20 mm, at least 22 mm, at least 24 mm or at least 25 mm. In various non-limiting embodiments, the head portion 302 of the anti-slip rivet 300 may comprise a diameter, ds, not exceeding 30 mm, not exceeding 25 mm, not exceeding 24 mm, not exceeding 22 mm, not exceeding 20 mm, not exceeding 18 mm, not exceeding 16 mm, such as, for example, not exceeding 15 mm, not exceeding 14 mm, not exceeding 12 mm, not exceeding 10 mm or not exceeding 7 mm. For example, in certain non-limiting embodiments, the head portion 302 of the anti-slip rivet 300 may comprise a diameter, ds, in a range from 4 mm to 30 mm, such as, for example, 5 Petition 870260055350, dated 08 / 06 / 2026, page 14 / 58 11 / 19mm to 25mm, 10mm to 18mm, 10mm to 14mm, 14mm to 18mm, 20mm to 25mm or 12mm to 14mm.

[0035] The manufacture of the anti-slip rivet 300 can balance the difficulty of producing the outer edge 306 and the anti-slip properties of the outer edge 306. For example, manufacturing the anti-slip rivet 300 with a cylindrical outer edge 306 can enhance the minimization or prevention of rivet slippage in a precision feed channel, although it may also present manufacturing challenges. In other embodiments, the outer edge 306 may comprise a frustoconical shape and / or a shallow taper which may reduce the difficulty of manufacturing the rivets, but may present challenges in ensuring that the rivets do not jam or slip in the channel. In several non-limiting embodiments, the outer edge 306 can be optimized for rapid production, such as, for example, a production rate of at least 50 rivets / min., such as, for example, at least 100 rivets / min., at least 200 rivets / min. or at least 220 rivets / min.

[0036] In several non-limiting embodiments, the head portion 302 may comprise an underfill area 312 positioned near the lower edge 314 of the head portion 302 and intermediate to the outer edge 306 and the lower edge 314. The underfill area 312 may be intentionally underfilled during the manufacture of the rivet 300 in order to minimize or prevent flash from the production process or other point formation in the underfill area 312, which may inhibit movement of the rivet 300 in a channel. Additionally, the underfill area 312 may be minimized in order to inhibit or prevent the underfill area from becoming a ramp surface that may otherwise cause rivet slippage.

[0037] In certain non-limiting modalities, a transition 310 Petition 870260055350, dated 08 / 06 / 2026, page 15 / 58 12 / 19 can be positioned intermediate to the outer edge 306 and an upper surface 308 of the head portion 302. The transition 310 can comprise, for example, a radius or a frustoconical shape.

[0038] The 300 anti-slip rivet may comprise a metal or a metal alloy. For example, the 300 anti-slip rivet may comprise an electrically conductive material suitable for supporting a resistance spot riveting welding process. In various non-limiting embodiments, the 300 anti-slip rivet may comprise at least one of aluminum, an aluminum alloy, iron, an iron alloy, titanium, and a titanium alloy.

[0039] In several non-limiting embodiments, the 300 anti-slip rivet may be a wider profile anti-slip rivet. With reference to Figures 4A-4C, a non-limiting embodiment of an alternative configuration of a 400 anti-slip rivet according to this disclosure is provided to show an embodiment of a wider profile anti-slip rivet.

[0040] During a resistance spot rivet welding process without a pilot hole, the inventors of the present disclosure observed that the stiffness of the head portion of an anti-slip rivet according to the present disclosure can affect the quality of the weld joint achieved. In certain non-limiting embodiments, reducing the stiffness of the head portion to accommodate the displacement of the head portion relative to the shank can be advantageous. The reduced stiffness can allow a portion of the head portion of the anti-slip rivet to be moved by an upper electrode of a resistance spot rivet welding system relative to the weld joint formed during the resistance spot rivet welding process. As a result, less compensation may be required for the movement of a lower electrode of the resistance spot rivet welding system towards the joint. Petition 870260055350, dated 08 / 06 / 2026, page 16 / 58 13 / 19 welding and a more desirable fusion of the anti-slip rivet for the assembly can be achieved.

[0041] Referring to the non-limiting embodiment illustrated in Figures 5A-5B, a 500 anti-slip rivet is provided with reduced stiffness in the head portion 302. The reduced stiffness can allow for a higher quality weld joint and a more desirable fusion of the 500 anti-slip rivet to an assembly compared to substantially identical rivets lacking the reduced stiffness. In order to reduce the stiffness of the head portion 302, the 500 anti-slip rivet comprises a first portion 518 of the head portion 302 having a first thickness, ti, and a second portion 520 having a second thickness, 12. The first thickness, ti, is less than the second thickness, t2, and the difference in thickness reduces stiffness in the head portion 302.For example, in certain non-limiting embodiments, the first thickness, ti, may be at least 0.1 mm less than the second thickness, Í2, such as, for example, at least 0.2 mm less than the second thickness, Í2, or at least 0.3 mm less than the second thickness, Í2. The head portion 302 may comprise various alternative geometries to achieve the reduction in thickness, such as, for example, a stepped profile, a tapered profile and / or a curved profile. The reduction in thickness may reduce the stiffness of the head portion 302 with respect to the axial displacement of the shank 304 along the longitudinal axis, Ai, without resulting in cracking of the head portion 302 during the spot rivet welding process due to excessive stresses associated with stiffness and high displacement.In several non-limiting embodiments, the anti-slip rivet comprises a plurality of notches 516 configured to assist in gas and material dispersion during a resistance spot rivet welding process. In certain non-limiting embodiments, as indicated in Figure 5A, the notches... Petition 870260055350, dated 08 / 06 / 2026, page 17 / 58 14 / 19 516 can be spaced along the lower edge 314 around the periphery of the head portion 302.
