A clamping portion (382) of a fixing member (380) can be seated on the upper surface of the guide groove (332) (e.g., the surface facing the first direction (+X direction)).

[0112] According to one embodiment, the second manufacturing device (300) may include a second support member (340). The second support member (340) may be positioned between the first core member (320) and the second core member (330). The second support member (340) may be fixed to the second core member (330). For example, the second support member (340) may be fixed to a surface (e.g., a bottom surface) facing the second direction (-X direction) of the second core member (330). The second support member (340) may be a component of an insert assembly (IA). The second support member (340) may be referred to as a 'support member' and / or a 'restraining member'.

[0113] According to one embodiment, the second support member (340) may include a portion (e.g., a support portion (342)) disposed between the outer portion (211) of the wearable electronic device (200) and the second core member (330). The second support member (340) may be configured to support the outer portion (211) of the wearable electronic device (200).

[0114] In one embodiment, the second support member (340) may include a soft material. For example, the second support member (340) may include a urethane material. The second support member (340) is a part that supports the outer part (211) of the wearable electronic device (200) by contacting the outer part (211). Since the second support member (340) includes a soft material, the outer part (211) of the wearable electronic device (200) being pressed by the second support member (340) during a polishing operation (e.g., the polishing operation (S300) of FIGS. 28 to 30) can be prevented or mitigated.

[0115] According to one embodiment, the second support member (340) may include a second body portion (341). The second body portion (341) may be disposed between the first body portion (321) and the second core member (330). The second body portion (341) may be fixed to a surface (e.g., a lower surface) facing the second direction (-X direction) of the second core member (330).

[0116] According to one embodiment, the second support member (340) may include a support portion (342). The support portion (342) may protrude or extend from the second body portion (341) toward the second hole (H2). For example, the support portion (342) may protrude or extend from the second body portion (341) in a first direction (+X direction) (e.g., upward). The support portion (342) may be positioned inside the second hole (H2). The support portion (342) may be positioned between the protrusion (322) and / or flange portion (323) of the first core member (320) and the second core member (330). The support portion (342) may be configured to support the wearable electronic device (200). For example, the support member (342) may be positioned on the outside of the wearable electronic device (200) and configured to support the outside part (211) by contacting the outside part (211) of the wearable electronic device (200).

[0117] According to one embodiment, the support member (342) may have a ring shape (or a cylindrical shape). An opening formed in the center of the ring-shaped support member (342) may be a third hole (H3). With the second support member (340) fixed to the second core member (330), the second hole (H2) and the third hole (H3) may have a partially overlapping area. The ring-shaped support member (342) may be adjacent to the inner surface of the second hole (H2) (e.g., the surface facing the axis (A) of the second hole (H2)).

[0118] According to one embodiment, a second surface (S3) (e.g., an inner surface) facing the axis (A) of the second support member (340) may include a second inclined surface (IS2). The second inclined surface (IS2) may be inclined such that the end facing the first direction (+X direction) of the second surface (S3) is located closer to the axis (A) than the end facing the second direction (-X direction) of the second surface (S3). For example, the second inclined surface (IS2) may be inclined such that the diameter of the end facing the first direction (+X direction) of the second inclined surface (IS2) is smaller than the diameter of the end facing the second direction (-X direction) of the second inclined surface (IS2). The second inclined surface (IS2) may have a tapered shape.

[0119] According to one embodiment, the second inclined surface (IS2) may be configured to be in contact with the outer portion (211) of the wearable electronic device (200). The normal (NL) of the second inclined surface (IS2) may be oriented in a direction toward the axis (A) (e.g., the inner direction (-R direction) of the radial direction) and an intermediate direction toward the second direction (-X direction). For example, the second inclined surface (IS2) (e.g., the second support member (340) and / or support member (342)) may support the wearable electronic device (200) in a direction toward the axis (A) (e.g., the inner direction (-R direction) of the radial direction) and the second direction (-X direction) (e.g., downward). For example, the second inclined surface (IS2) may be configured to support the wearable electronic device (200) downward. Through this structure, the wearable electronic device (200) can be firmly fixed by the first core member (320) and the second support member (340).

[0120] According to one embodiment, the second manufacturing device (300) may include a masking member (350). The masking member (350) may be positioned on the first direction (+X direction) side (e.g., upward) of the second core member (330). The masking member (350) may be positioned on the first direction (+X direction) side (e.g., upward) of the second support member (340) (e.g., support member (342)). The masking member (350) may overlap the second core member (330) and the second support member (340) in the first direction (+X direction). According to one embodiment, the masking member (350) may be configured to cover at least the second core member (330) and the second support member (340) in the first direction (+X direction).

[0121] According to one embodiment, the masking member (350) may include at least one third hole (H3). The third hole (H3) may be formed at a position corresponding to the second hole (H2). The third hole (H3) may be formed by penetrating the first direction (+X direction) and / or the second direction (-X direction) (e.g., the axis (A) direction) of the masking member (350). At least a portion of the wearable electronic device (200) may be exposed to the polishing member (370) through the third hole (H3).

[0122] According to one embodiment, the third hole (H3) may include a plurality of third holes (H3). For example, the third hole (H3) may be formed in a plurality. For example, as shown in FIG. 6, six third holes (H3) may be provided. The plurality of third holes (H3) may be formed at positions corresponding to the plurality of second holes (H2). The plurality of third holes (H3) may be formed at positions corresponding to the plurality of protrusions (322).

[0123] According to one embodiment, the third hole (H3) may have a smaller diameter than the second hole (H2). For example, the diameter (d2) of the third hole (H3) may be smaller than the diameter (d1) of the second hole (H2). For example, the edge facing the axis (A) of the masking member (350) (e.g., the edge of the third hole (H3)) may be positioned closer to the axis (A) (e.g., inside) than the edge facing the axis (A) of the second core member (330) (e.g., the edge of the second hole (H2)). This allows the masking member (350) to cover at least the second core member (330) and the second support member (340) in the first direction (+X direction), and enables partial polishing of the inner part (212) of the wearable electronic device (200).

[0124] According to one embodiment, the masking member (350) may be configured to inhibit wear of at least one of the outer part (211) of the wearable electronic device (200), the second support member (340), or the second core member (330) by covering at least the second support member (340) and the second core member (330). For example, the masking member (350) may be configured to inhibit wear of the outer part (211) of the wearable electronic device (200). It may be preferable that the polishing operation of the wearable electronic device (200) (e.g., the polishing operation (S300) of FIGS. 28 to 30) be partially performed on the inner part (212) and not on the outer part (211) made of metal material. In one embodiment, by limiting the portion where the masking member (350) contacts the polishing member (370) and the wearable electronic device (200) to the inner portion (212) of the wearable electronic device (200), partial polishing of the inner portion (212) of the wearable electronic device (200) can be effectively performed. For example, the masking member (350) may be configured to suppress wear of the second core member (330). By preventing the second core member (330) and the polishing member (370) from coming into contact with each other through the masking member (350), physical wear of the second core member (330) by the polishing member (370) or chemical wear of the second core member (330) caused by an abrasive (e.g., polishing agent) containing aluminum oxide (Al2O₃) reacting with the second core member (330) can be prevented or mitigated. For example, the masking member (350) may be configured to suppress wear of the second support member (340). By preventing the second support member (340) and the polishing member (370) from coming into contact with each other through the masking member (350), physical wear of the second support member (340) by the polishing member (370) may be prevented or mitigated.

[0125] According to one embodiment, the masking member (350) may be positioned on the first direction (+X direction) side of a part of the wearable electronic device (200) (e.g., the top of the wearable electronic device (200)). For example, the masking member (350) may be positioned on the first direction (+X direction) side of a part of the outer portion (211) of the wearable electronic device (200). For example, the diameter (d2) of the third hole (H3) may be smaller than the outer diameter of the wearable electronic device (200). For example, the masking member (350) may overlap the part of the outer portion (211) of the wearable electronic device (200) in the first direction (+X direction). The masking member (350) may be configured to cover a part of the outer portion (211) of the wearable electronic device (200). In one embodiment, the masking member (350) may not overlap with the outer part (211) of the wearable electronic device (200) in the first direction (+X direction). For example, the diameter (d2) of the third hole (H3) may be larger than the outer diameter of the wearable electronic device (200). Even if the diameter (d2) of the third hole (H3) is larger than the outer diameter of the wearable electronic device (200), if the edge facing the axis (A) of the masking member (350) (e.g., the edge of the third hole (H3)) has sufficient thickness in the first direction (+X direction), the outer part (211) of the wearable electronic device (200) may be prevented from being worn by the polishing member (370) (e.g., the polishing member (370) of FIG. 6).

[0126] According to one embodiment, the masking member (350) may be fixed to the second core member (330). The masking member (350) may be fixed to the second core member (330) by a masking guide member (360). For example, the masking member (350) may be welded to the masking guide member (360). In one embodiment, the masking member (350) may be fixed to the second core member (330) by a separate coupling member (not shown) penetrating the masking member (350) and being coupled to the second core member (330).

[0127] According to one embodiment, the masking member (350) may include a hard carbide material. The hard carbide material may include a carbide material. Carbide is a material that has high hardness and does not chemically react with an abrasive (e.g., a polishing agent), and by including a carbide material in the masking member (350), the masking member (350) can be used substantially permanently.

[0128] According to one embodiment, the edge facing the axis (A) of the masking member (350) may have a length (L) in the first direction (+X direction). For example, the edge facing the axis (A) of the masking member (350) (e.g., the edge of the third hole (H3)) may include an inner surface (S1) facing the axis (A) and having a length (L) in the first direction (+X direction). For example, the surface facing the axis (A) of the masking member (350) (e.g., the inner surface (S1) of the third hole (H3)) may have a length of about 0.15 mm in the first direction (+X direction). Since the masking member (350) includes a high-hardness carbide material, the edge facing the axis (A) of the masking member (350) has thickness in the first direction (+X direction), thereby preventing or mitigating damage to the edge facing the axis (A) of the masking member (350).

[0129] According to one embodiment, the edge of the masking member (350) facing the axis (A) (e.g., inner edge or edge of the third hole (H3)) may be spaced apart from the edge of the outer part (211) of the wearable electronic device (200) facing the axis (A) (e.g., inner edge) in a direction away from the axis (A) (e.g., radially outward). For example, the edge of the third hole (H3) may be spaced apart from the end facing the first direction (+X direction) of the boundary between the outer part (211) of the wearable electronic device (200) and the inner part (212) of the wearable electronic device (200) in a direction away from the axis (A). For example, the edge facing the axis (A) of the masking member (350) (e.g., inner edge) may be spaced about 0.5 mm apart from the edge facing the axis (A) of the outer part (211) of the wearable electronic device (200) (e.g., inner edge). Through this structure, a cylindrical polishing member (370) having a large radius can come into contact with the inner part (212) of the wearable electronic device (200), even though the edge facing the axis (A) of the masking member (350) (e.g., edge of the third hole (H3)) has thickness in the first direction (+X direction).

[0130] According to one embodiment, a first surface (S2) (e.g., the upper surface of the masking member (350)) facing the first direction (+X direction) of the masking member (350) may include a first inclined surface (IS1). The first inclined surface (IS1) may be inclined such that the portion far from the axis (A) of the first surface (S2) is located on the second direction (-X direction) side (e.g., downward) of the portion close to the axis (A) of the first surface (S2). For example, the first inclined surface (IS1) may be inclined about 8.5 degrees with respect to a plane perpendicular to the axis (A) (e.g., a plane perpendicular to the first direction (+X direction) and / or the second direction (-X direction)). The first inclined surface (IS1) may be understood to have a funnel shape (e.g., a tapered shape) toward the axis (A). The first inclined surface (IS1) can be configured to suppress interference between the edge (e.g., inner edge) facing the axis (A) of the polishing member (370) and the masking member (350) so that polishing of the inner part (212) of the wearable electronic device (200) is effectively performed.

[0131] According to one embodiment, the masking member (350) may include a tapered portion (351). The tapered portion (351) may be formed such that the length in the first direction (+X direction) of the portion closer to the axis (A) of the masking member (350) is smaller than the length in the first direction (+X direction) of the portion further from the axis (A) of the masking member (350). For example, the tapered portion (351) may be a portion whose thickness increases in the first direction (+X direction) as it moves further away from the axis (A). The tapered portion (351) may be positioned adjacent to the edge facing the axis (A) of the masking member (350). For example, the tapered portion (351) may be positioned in an area adjacent to the third hole (H3). Through this, the structural rigidity of the masking member (350) containing a high-hardness carbide material is improved, so that damage to the masking member (350) can be prevented or mitigated.

[0132] According to one embodiment (Fig. 9), the tapered portion (351) may include a first tapered portion (3511). The first tapered portion (3511) may be a portion of the tapered portion (351) adjacent to the axis (A). The upper surface of the first tapered portion (3511) (e.g., a surface facing the first direction (+X direction)) may be a first inclined surface (IS1). The lower surface of the first tapered portion (3511) (e.g., a surface facing the second direction (-X direction)) may extend along a plane perpendicular to the axis (A). By having a structure in which the lower surface of the first tapered portion (3511) extends along a plane perpendicular to axis 1, interference between the masking member (350) and the second support member (340) can be prevented or mitigated.

[0133] According to one embodiment (Fig. 9), the tapered portion (351) may include a second tapered portion (3512). The second tapered portion (3512) may be a portion of the tapered portion (351) that is positioned further from the axis (A) than the first tapered portion (3511). A portion of the upper surface of the second tapered portion (3512) (e.g., a surface facing the first direction (+X direction)) may be a first inclined surface (IS1). The lower surface of the second tapered portion (3512) (e.g., a surface facing the second direction (-X direction)) may include a third inclined surface (IS3) that is inclined toward the second direction (-X direction) as it moves further from the axis (A). Through the second tapered portion (3512), the structural rigidity of the masking member (350) can be effectively secured.

[0134] According to one embodiment (Fig. 10), a third surface (S4) (e.g., bottom surface) facing the second direction (-X direction) of the tapered portion (351) and / or the masking member (350) may include a third inclined surface (IS3) that slopes in the second direction (-X direction) as it moves away from the axis (A). The third inclined surface (IS3) may be positioned in the portion of the bottom surface of the masking member (350) (e.g., the surface facing the second direction (-X direction)) adjacent to the axis (A). For example, the third inclined surface (IS3) may extend from the edge facing the axis (A) of the masking member (350) (e.g., the edge of the third hole (H3)). Through this structure, the rigidity of the area adjacent to the axis (A) of the masking member (350) can be secured more effectively.

[0135] According to one embodiment, the masking member (350) may be configured to be replaceable. For example, the masking member (350) may be detachably coupled to the masking guide member (360). For example, the masking member (350) and the masking guide member (360) may be detachably coupled to the second core member (330).

[0136] According to one embodiment, the masking member (350) and the wearable electronic device (200) may be spaced apart from each other. For example, the masking member (350) and the wearable electronic device (200) may be spaced apart by at least 0.15 mm. This prevents or mitigates the occurrence of indentations on the exterior of the wearable electronic device (200) by the masking member (350) causing the wearable electronic device (200) to come into contact with each other.

[0137] According to one embodiment, the second manufacturing device (300) may include a masking guide member (360). The masking guide member (360) may be placed in a guide groove (332) formed in at least a portion of the edge of the second core member (330). The masking guide member (360) may be placed between the second core member (330) and the masking member (350). The masking member (350) and the masking guide member (360) may be joined together. For example, the masking member (350) and the masking guide member (360) may be welded together. By placing the masking guide member (360) in the guide groove (332) of the second core member (330) while welded to the masking member (350), the position of the masking member (350) may be guided.

[0138] According to one embodiment, with reference to FIG. 6, the second manufacturing device (300) may include a polishing member (370). The polishing member (370) may have a cylindrical shape. The polishing member (370) may rotate around a rotation axis (RA) centered on a direction perpendicular to the axis (A). The polishing member (370) may include a deformable material. For example, the polishing member (370) may have a structure in which bristles are arranged radially around the rotation axis (RA). The polishing member (370) may be deformed during the polishing process by being pressed by the protrusion (322) of the first core member (320), the insert assembly (IA), and / or the wearable electronic device (200).

[0139] According to one embodiment, the second manufacturing device (300) may include a fixing member (380). The fixing member (380) may be positioned on the side of the insert assembly (IA). The fixing member (380) may be positioned at a location corresponding to a fixing hole (312) formed in the second base portion (310). The fixing member (380) may be coupled to the fixing hole (312). The fixing member (380) may be configured to fix the insert assembly (IA) seated in the seating groove (311) to the second base portion (310).

[0140] According to one embodiment, the fixing member (380) may include a column portion (381). The column portion (381) may extend in a first direction (+X direction) and / or a second direction (-X direction). The column portion (381) may be inserted into a fixing hole (312). According to one embodiment, the fixing member (380) may include a clamping portion (382). The clamping portion (381) may protrude outwardly from the column portion (381). With the fixing member (380) fixing the insert assembly (IA), the clamping portion (381) may be seated on a guide groove (332).

[0141] According to one embodiment, the fixing member (380) and / or the fixing hole (312) may be joined in a 'swing clamp' manner. For example, referring to FIG. 11, the fixing member (380) may be configured to fix the insert assembly (IA) to the second base portion (310) in a 'swing clamp' manner. Referring to FIG. 11, with the insert assembly (IA) seated in the second base portion (310) (e.g., the seating groove (311) of FIG. 6), the column portion (381) of the fixing member (380) may be inserted into the fixing hole (312). As the fixing member (380) is drawn into the fixing hole (312) (e.g., as the fixing member (380) moves in the second direction (-X), the fixing member (380) and the clamping portion (382) may rotate. As the movement of the fixed member (380) is completed, the rotated clamping member (382) can be seated on a guide groove (332) formed in the insert assembly (IA) (e.g., the second core member (330)). The insert assembly (IA) can be fixed to the second base member (310) by the upper surface of the guide groove (332) (e.g., the surface facing the first direction (+X direction)) engaging with the clamping member (382). The movement of the fixed member (380) in the first direction (+X direction) and / or the second direction (-X direction) and the rotation of the fixed member (380) may be performed by air pressure or may be performed manually by an operator.

[0143] Specifically, FIG. 12 is a perspective view of the first manufacturing device (400). FIG. 13 is an enlarged perspective view of a part of the first manufacturing device (400). FIG. 14 is a plan view of the first manufacturing device (400) viewed from the first direction (+X direction).

FIG. 20 is a perspective view of the inner guide member.

[0144] Hereinafter, the axis (A) may refer to a ring-shaped axis of the ring-type wearable electronic device (200). The first direction (+X direction) is one of the directions parallel to the axis (A) and may refer to the +X direction based on FIGS. 12 to 17. The second direction (-X direction) is a direction opposite to the first direction (+X direction) and may refer to the -X direction, which is the other direction parallel to the axis (A) based on FIGS. 12 to 17. The outer direction (+R direction) among the radial directions is a direction moving away from the axis (A) and may refer to the +R direction based on FIGS. 12 to 17. The inner direction (-R direction) among the radial directions is a direction moving closer to the axis (A) and may refer to the -R direction based on FIGS. 12 to 17.

[0145] Hereinafter, a first manufacturing device (400) according to one embodiment of the present disclosure may include a first base part (410), a protrusion (420), a seating member (430), an inner guide member (480), a driving part (450), a connecting part (460), and a first support member (470), but some of these may be omitted and implemented, and additional configurations other than those may not be excluded.

[0146] According to one embodiment, the wearable electronic device (200) may include a processed portion (213). The processed portion (213) is a portion that is cut and removed by a CNC process (e.g., a cutting operation (S200)), and may be a portion remaining in the gate portion after the inner portion (212) in a liquid state is injected (e.g., the injection and curing operation (S100) of FIG. 21). The processed portion (213) may be a part of the inner portion (212) before processing. The processed portion (213) may be a portion extending from the inner portion (212) in a first direction (+X direction). The processed portion (213) may be formed along the entire circumference centered on the axis (A) of the inner portion (212) of the ring-shaped wearable electronic device (200). A structure in which the processing portion (213) is formed along the circumference centered on the axis (A) of the inner portion (212) can be referred to as an 'open gate structure'. In such an open gate structure, since the CNC process (e.g., the cutting operation (S200) of FIGS. 24 to 27) must be performed along the entire circumference centered on the axis (A) of the inner portion (212), the processing surface of the inner portion (212) can have a uniform appearance quality after the CNC process (e.g., the cutting operation (S200)).

[0147] According to one embodiment, the first manufacturing device (400) may be a device for a CNC process. For example, the first manufacturing device (400) may be used in a CNC process for cutting an inner part (212) of a wearable electronic device (200) to a target shape. The first manufacturing device (400) may be a jig of manufacturing equipment used in the manufacturing process of the wearable electronic device (200). The first manufacturing device (400) may be referred to as a 'manufacturing device', 'CNC device', 'jig', and / or 'CNC jig'.

[0148] According to one embodiment, the first manufacturing device (400) may include a first base portion (410). The first base portion (410) may be a basic structure of the first manufacturing device (400). A seating member (430), a support member (470), a driving member (450), and an inner guide member (480) may be disposed on the first base portion (410). The first base portion (410) may be referred to as the 'base portion'.

[0149] According to one embodiment, the first manufacturing device (400) may include a protrusion (420). The protrusion (420) may protrude from the first base part (410) in a first direction (+X direction). The protrusion (420) may be positioned on the outside of the seating member (430). For example, the protrusion (420) may be positioned to surround the outer surface of the seating member (430). For example, a space open in the first direction (+X direction) and / or the second direction (-X direction) may be formed in the region of the protrusion (420) adjacent to the axis (A), and the seating member (430) may be positioned in the open space of the protrusion (420). The protrusion (420) may be provided integrally with the first base part (410), or it may be provided separately from the first base part (410) and coupled to the first base part (410).

[0150] According to one embodiment, the first manufacturing device (400) may include a seating member (430). The seating member (430) may be placed on the first base portion (410). For example, the seating member (430) may be placed on the first direction (+X direction) side (e.g., top) of the first base portion (410). The seating member (430) may be placed inside the protrusion (420). For example, the seating member (430) may be placed in an open space formed in the region adjacent to the axis (A) of the protrusion (420). The seating member (430) may be formed integrally with the first base portion (410) and / or the protrusion (420), or it may be provided separately from the first base portion (410) and / or the protrusion (420) and coupled to the first base portion (410) and / or the protrusion (420).

[0151] According to one embodiment, the seating member (430) may be positioned on the outside of the inner guide member (480). For example, the seating member (430) may be positioned to surround the outer surface of the inner guide member (480). For example, a space open in a first direction (+X direction) and / or a second direction (-X direction) may be formed in an area of ​​the seating member (430) adjacent to the axis (A). For example, the seating member (430) may have a roughly cylindrical shape open in the first direction (+X direction) and / or a second direction (-X direction). The inner guide member (480) may be positioned in the open space of the seating member (430).

[0152] According to one embodiment, the mounting member (430) may be configured to support the wearable electronic device (200) in a first direction (+X direction) parallel to the axis (A) (e.g., upward). For example, the wearable electronic device (200) may be mounted on the mounting member (430). The wearable electronic device (200) may be mounted such that the surface of the wearable electronic device (200) facing the second direction (-X direction) faces the surface of the mounting member (430) facing the first direction (+X direction).

[0153] According to one embodiment, the first manufacturing device (400) may include a restraint assembly (CA). The restraint assembly (CA) may be disposed on the first base portion (410). The restraint assembly (CA) may include a driving portion (450), a connecting portion (460), and a support member (470).

[0154] According to one embodiment, the first manufacturing device (400) may include a driving unit (450). The driving unit (450) may be fixed on the first base unit (410). The driving unit (450) may be configured to provide a driving force for reciprocating motion in a direction toward the axis (A) of the connecting unit (460) and the first support member (470) (e.g., the inner direction (-R direction) in the radial direction) and / or a direction away from the axis (A) (e.g., the outer direction (+R direction) in the radial direction). For example, the driving unit (450) may be provided with a pneumatic cylinder and / or a hydraulic cylinder.

[0155] According to one embodiment, for a wearable electronic device (200), driving units (450) may be provided in pairs. For example, the driving units (450) may be positioned opposite each other in a direction perpendicular to a first direction (+X direction) with respect to the wearable electronic device (200) (e.g., a direction toward the axis (A) and / or a direction away from the axis (A)).

[0156] According to one embodiment, the first manufacturing device (400) may include a connecting part (460). The connecting part (460) may be positioned on the side facing the axis (A) of the driving part (450). The connecting part (460) may be positioned between the wearable electronic device (200) and / or the first support member (470) and the driving part (450). The connecting part (460) may be a bracket to which the first support member (470) can be fixed. The connecting part (460) may move linearly in a direction facing the axis (A) (e.g., the inner direction of the radial direction (-R direction)) and / or a direction away from the axis (A) (e.g., the outer direction of the radial direction (+R direction)) by a driving force provided by the driving part (450). The connecting part (460) may be referred to as a 'bracket'.

[0157] According to one embodiment, for a wearable electronic device (200), the connecting portion (460) may be provided in pairs. For example, the connecting portion (460) may be positioned opposite each other in a direction perpendicular to the first direction (+X direction) with respect to the wearable electronic device (200) (e.g., a direction toward the axis (A) and / or a direction away from the axis (A)).

[0158] According to one embodiment, the first manufacturing device (400) may include a first support member (470). The first support member (470) may be positioned on the side facing the axis (A) of the connecting part (460). The first support member (470) may be positioned between the wearable electronic device (200) and the connecting part (460). The first support member (470) may be positioned on the outside of the outer part (211) of the wearable electronic device (200). For example, the first support member (470) may be positioned on the side far from the axis (A) of the outer part (211) of the wearable electronic device (200) (e.g., radially outward). The first support member (470) may support the outer part (211) of the wearable electronic device (200). The first support member (470) may be referred to as a 'support member' and / or a 'restraint member'.

[0159] According to one embodiment, for a wearable electronic device (200), the first support members (470) may be provided in pairs. For example, the first support members (470) may be positioned opposite each other in a direction perpendicular to the first direction 1 with respect to the wearable electronic device (200) (e.g., a direction toward the axis (A) and / or a direction away from the axis (A)).

[0160] According to one embodiment, the first support member (470) can be fixed to the connecting part (460). For example, the first support member (470) can be detachably fixed to the connecting part (460). This allows the first support member (470) to be easily replaced according to the size of the wearable electronic device (200) that requires processing.

[0161] According to one embodiment, the first support member (470) can move linearly in a direction toward the axis (A) (e.g., the inner direction of the radial direction (-R direction)) and / or in a direction toward the axis (A) (e.g., the outer direction of the radial direction (+R direction)) by a driving force provided by the driving unit (450). When the first support member (470) is in a state toward the axis (A), the wearable electronic device (200) can be placed on the seating member (430), and when the first support member (470) moves toward the axis (A), the wearable electronic device (200) can be supported or restrained by the first support member (470).

[0162] According to one embodiment, the first support member (470) may include at least one of polyoxymethylene (POM) or urethane material. For example, the first support member (470) may include a POM material with low elasticity. Since high positional precision of the wearable electronic device (200) is required in the CNC process, it may be preferable for the first support member (470) that restrains the position of the wearable electronic device (200) to include a POM material with low elasticity. In one embodiment, the first support member (470) may include a urethane material to prevent indentation of the outer part (211) of the wearable electronic device (200).

[0163] According to one embodiment, the first support member (470) may include a plurality of supporting parts (472). The plurality of supporting parts (472) may come into contact with an outer part (211) of the wearable electronic device (200). For example, the plurality of supporting parts (472) may be parts where the first support member (470) and the wearable electronic device (200) come into contact with each other when the first support member (470) moves toward the wearable electronic device (200). The plurality of supporting parts (472) may be parts of the first support member (470) that protrude toward the wearable electronic device (200). For example, the wearable electronic device (200) may be understood as being point-supported by the plurality of supporting parts (472).

[0164] According to one embodiment, a plurality of support parts (472) may be arranged radially around an axis (A). For example, referring to FIG. 14, a plurality of support parts (472) may be arranged radially around an axis (A) when viewed from the first direction (+X direction). It can be understood that the wearable electronic device (200) is point-supported at a radial point through the plurality of support parts (472) arranged radially. Through this, the wearable electronic device (200) can be stably supported by the first support member (470) regardless of the size of the wearable electronic device (200). In addition, the plurality of support parts (472) can suppress errors in arrangement due to deviations in the size or shape of the wearable electronic device (200).

[0165] According to one embodiment, a plurality of support parts (472) may be arranged equidistantly around an axis (A) when viewed from a first direction (+X direction). For example, when viewed from a first direction (+X direction), the angle between each of the plurality of support parts (472) may be the same. This prevents or mitigates deformation or damage to the wearable electronic device (200) when the wearable electronic device (200) is supported by the first support member (470) due to the support force being biased in one direction.

[0166] According to one embodiment, with reference to FIG. 17, the tangent plane at the point where a plurality of support portions (472) and an outer portion (211) of a wearable electronic device (200) come into contact (e.g., the tangent plane (TP) of the wearable electronic device (200) and the first support portion (473) and / or the second support portion (474)) may be inclined such that the normal (NL) of the tangent plane (TP) is oriented toward the axis (A) (e.g., the inner direction (-R direction) in the radial direction) and the second direction (-X direction). For example, the angle (a) between the tangent plane (TP) and the axis (A) may be about 15 degrees. For example, the first support member (470) may be understood as supporting the wearable electronic device (200) downward in the direction toward the axis (A) (e.g., the inner direction (-R direction) in the radial direction) and the second direction (-X direction). The wearable electronic device (200) can be stably supported by being supported upward by the seating member (430) and supported downward by the first support member (470).

[0167] According to one embodiment, each of the plurality of support portions (472) may support the wearable electronic device (200) by contacting a portion of the outer portion (211) of the wearable electronic device (200) that protrudes away from the axis (A) (e.g., the outer direction (+R direction) of the radial direction). The outer portion (211) of the wearable electronic device (200) according to one embodiment may include a first portion (2111) that protrudes away from the axis (A) (e.g., the outer direction (+R direction) of the radial direction) in an area facing the first direction (+X direction) (e.g., an upper area), and a second portion (2112) that protrudes away from the axis (A) (e.g., the outer direction (+R direction) of the radial direction) in an area facing the second direction (-X direction) (e.g., a lower area). Each of the plurality of support portions (472) can support the wearable electronic device (200) by contacting the first portion (2111) and the second portion (2112). For example, in each of the plurality of support portions (472), the first support member (470) can be understood as supporting the wearable electronic device (200) at two points. Through such a structure, the wearable electronic device (200) can be supported in both the upper region and the lower region, so the wearable electronic device (200) can be stably supported.

[0168] According to one embodiment, each of the plurality of supporting portions (472) may include a first supporting portion (473). The first supporting portion (473) may be positioned in a region (e.g., upper region) facing the first direction (+X direction) among the plurality of supporting portions (472). The first supporting portion (473) may protrude from the supporting body portion (471) of the first supporting member (470) in a direction facing the axis (A) (e.g., inward direction (-R direction) in the radial direction). The first supporting portion (473) may come into contact with the first portion (2111) of the wearable electronic device (200).

[0169] According to one embodiment, each of the plurality of support portions (472) may include a second support portion (474). The second support portion (474) may be positioned in a region (e.g., a lower region) facing the second direction (-X direction) among the support portions (472). The second support portion (474) may protrude from the support body portion (471) of the first support member (470) in a direction facing the axis (A) (e.g., an inner direction (-R direction) in the radial direction). The second support portion (474) may come into contact with the second portion (2112) of the wearable electronic device (200).

[0170] According to one embodiment, each of the plurality of support portions (472) may have a curved surface. For example, referring to FIG. 18, the first support portion (473) may be connected to an area adjacent to the first support portion (473) by a streamlined curved surface, and the second support portion (474) may be connected to an area adjacent to the second support portion (474) by a streamlined curved surface. For example, it may be understood that each of the plurality of support portions (472) does not include an angled portion. Through such a structure, in the process of the wearable electronic device (200) coming into contact with the plurality of support portions (472), it is possible to prevent or mitigate the occurrence of indentation on the wearable electronic device (200) by the plurality of support portions (472).

[0171] According to one embodiment, the first manufacturing device (400) may include an inner guide member (480). The inner guide member (480) may be placed in a space (e.g., an opening) facing the axis (A) of the wearable electronic device (200). The inner guide member (480) may be placed in a space opened in a first direction (+X direction) and / or a second direction (-X direction) in an area adjacent to the axis (A) of the seating member (430).

[0172] According to one embodiment, the inner guide member (480) may be configured to perform a lifting motion that rises in a first direction (+X direction) or descends in a second direction (-X direction). A wearable electronic device (200) may be placed along the outer surface of the inner guide member (480) that has risen in the first direction (+X direction). The inner guide member (480) may guide the position where the wearable electronic device (200) is placed. The inner guide member (480) may be configured to descend in a second direction (-X direction) after the first support member (470) moves in a direction toward the axis (A) (e.g., the inner direction (-R direction) among the radial directions) to support the wearable electronic device (200). By proceeding with the CNC process (e.g., the cutting process (S200) of FIGS. 22 to 27) in a lowered state of the inner guide member (480), the occurrence of indentation of the wearable electronic device (200) by the inner guide member (480) can be suppressed. In one embodiment, the inner guide member (480) may be configured not to be raised. The inner guide member (480) may be provided integrally with the seating member (430). The CNC process (e.g., the cutting process (S200) of FIGS. 22 to 27) may be performed in a state where the inner guide member (480) is not lowered.

[0173] According to one embodiment, the outer surface of the portion of the inner guide member (480) facing the first direction (+X direction) may correspond at least partially to the shape of the surface facing the axis (A) of the wearable electronic device (200) (e.g., the surface facing the axis (A) of the inner portion (212)). Through this, the wearable electronic device (200) can be stably seated on the inner guide member (480).

[0174] According to one embodiment, the inner guide member (480) may include a recessed portion (481). The recessed portion (481) may be formed on the outer surface of the inner guide member (480). The recessed portion (481) may be recessed toward the axis (A). The recessed portion (481) may be formed in a position facing at least a portion of a plurality of support portions (472). For example, the recessed portion (481) may be formed in a position facing a plurality of support portions (472) of one of the first support members (470) provided in pairs. For example, in the recessed portion (481), a gap of at least 0.5 mm may be formed between the outer surface of the inner guide member (480) and the inner portion (212) of the wearable electronic device (200). Through the recess portion (481), the supporting force of the plurality of supporting portions (472) is concentrated on the wearable electronic device (200), thereby preventing or mitigating the occurrence of indentation on the outer surface of the wearable electronic device (200) or deformation of the shape of the wearable electronic device (200).

[0175] According to one embodiment, the inner guide member (480) may include a polyether ether keton (PEEK) material. PEEK is a plastic-based material with relatively high rigidity, and can be precisely machined to correspond to the shape of the inner part (212) of the wearable electronic device (200). In addition, since PEEK has a softer hardness compared to metal materials such as aluminum, it can prevent or mitigate the occurrence of indentation on the inner part (212) of the wearable electronic device (200) by the inner guide member (480) during the CNC process.

[0176] FIGS. 21 to 30 illustrate the manufacturing process of a wearable electronic device according to one embodiment of the present disclosure.

[0177] Specifically, FIG. 21 is a flowchart illustrating the manufacturing process of a wearable electronic device according to one embodiment of the present disclosure. FIGS. 22 and 23 illustrate a wearable electronic device (200) before performing a cutting operation (S200) by a second manufacturing device (300). FIGS. 24 to 27 illustrate the cutting operation (S200) by the second manufacturing device (300). FIGS. 28 to 30 illustrate the polishing operation (S300) by the first manufacturing device (400).

[0178] According to one embodiment, with reference to FIG. 21, a method for manufacturing a wearable electronic device (200) may include an operation (S100) of injecting and curing an inner part (212) in a liquid state and a processed part (213) into the inner part of an outer part (211) configured to form an outer surface facing away from the axis (A) of the wearable electronic device (200) (e.g., the outer direction (+R direction) among the radial directions). The part into which the inner part (212) in a liquid state and the processed part (213) are injected may be referred to as a 'gate'. According to one embodiment, the gate may be formed along the circumference centered on the axis (A) of the wearable electronic device (200). After injecting the inner part (212) in a liquid state and undergoing a curing process, the inner part (212) may be changed to a solid state.

[0179] According to one embodiment, with reference to FIGS. 22 and FIGS. 23, a wearable electronic device (200) that has undergone a curing process may include a processed portion (213). The processed portion (213) is a portion that is cut and removed by a CNC process (e.g., a cutting operation (S200)), and may be a portion remaining in the gate portion after the inner portion (212) in a liquid state has been injected. The processed portion (213) may be a part of the inner portion (212) before processing. The processed portion (213) may be a portion that extends from the inner portion (212) in a first direction (+X direction). The processed portion (213) may be formed along the entire circumference centered on the axis (A) of the inner portion (212) of the ring-shaped wearable electronic device (200). A structure in which the processing portion (213) is formed along the circumference centered on the axis (A) of the inner portion (212) can be referred to as an ‘open gate structure.’ In this open gate structure, since the CNC process (e.g., cutting operation (S200)) must be performed along the entire circumference centered on the axis (A) of the inner portion (212), the processing surface of the inner portion (212) can have a uniform appearance quality after the CNC process (e.g., cutting operation (S200)).

[0180] According to one embodiment, with reference to FIGS. 21 and FIGS. 24 to 27, a method for manufacturing a wearable electronic device (200) may include placing the wearable electronic device (200) in a first manufacturing device (400) for CNC machining and cutting a machined portion (213) of the wearable electronic device (200). In the cutting operation (S200), the machined portion (213) may be removed.

[0181] According to one embodiment, with reference to FIG. 24, the cutting operation (S200) may include an operation (S201) of placing a wearable electronic device (200) on the mounting member (430) and on the outside of the inner guide member (480). The first support member (470) may be placed in a position that is moved or retracted in a direction away from the axis (A) (e.g., the outer direction (+R direction) of the radial direction). The inner guide member (480) may be in a state that is raised in the first direction (+X direction). The wearable electronic device (200) may be placed on the mounting member (430) (e.g., on the side of the first direction (+X direction) of the mounting member (430). The wearable electronic device (200) may be placed along the perimeter of the inner guide member (480). For example, a wearable electronic device (200) can be fitted into an inner guide member (480). Since the shape of the inner surface of the wearable electronic device (200) (e.g., inner part (212)) corresponds at least partially to the shape of the outer surface of the inner guide member (480), the wearable electronic device (200) can be stably seated on the outer surface of the inner guide member (480).

[0182] According to one embodiment, with reference to FIG. 25, the cutting operation (S200) may include an operation (S202) of moving the first support member (470) in a direction toward the axis (A) (e.g., an inner direction (-R direction) among the radial directions) so that a plurality of support portions (472) arranged radially around the axis (A) of the first support member (470) disposed on the outside of the wearable electronic device (200) support the outer portion (211). When the first support member (470) moves toward the wearable electronic device (200), the plurality of support portions (472) of the first support member (470) may come into contact with the outer surface of the outer portion (211) of the wearable electronic device (200). The wearable electronic device (200) can be radially and stably supported by the first support member (470) at a radial position (e.g., an equal position around the axis (A)) centered on the axis (A). The wearable electronic device (200) can be stably supported by the first manufacturing device (400) by being supported in the outer direction (+R direction) and the first direction (+X direction) in the radial direction by the inner guide member (480), and by being supported in the inner direction (-R direction) and the second direction (-X direction) in the radial direction by the first support member (470).

[0183] According to one embodiment, with reference to FIG. 26, the cutting operation (S200) may include an operation (S203) in which the inner guide member (480) descends in a second direction (-X direction). By descending the inner guide member (480), interference between the cutting member (e.g., the cutting member (490) of FIG. 27 or a gun tool) and the inner guide member (480) can be prevented. Additionally, by descending the inner guide member (480), indentation caused by the inner guide member (480) on the inner part (212) of the wearable electronic device (200) can be prevented or mitigated. In one embodiment, the operation (S203) in which the inner guide member (480) descends in the second direction (-X direction) may be omitted. For example, if the inner guide member (480) is integrally provided with the seating member (430), the downward movement of the inner guide member (480) may be omitted.

[0184] According to one embodiment, with reference to FIG. 27, the cutting operation (S200) may include the operation (S204) of cutting a processed portion (213) of a wearable electronic device (200) (e.g., the processed portion (213) of FIG. 22 and FIG. 23) through a cutting member (490).

[0185] According to one embodiment, with reference to FIGS. 21 and FIGS. 28 to 30, a method for manufacturing a wearable electronic device (200) may include placing the wearable electronic device (200) in a second manufacturing device (300) for polishing and polishing an inner portion (212) of the wearable electronic device (200).

[0186] According to one embodiment, with reference to FIG. 28, the polishing operation (S300) may include the operation (S301) of placing a wearable electronic device (200) on a first core member (320). The wearable electronic device (200) may be fitted into a protrusion (322) of the first core member (320). The protrusion (322) of the first core member (320) may be inserted into a first hole (H1) of the wearable electronic device (200). For example, the wearable electronic device (200) may be supported by the protrusion (322) in a direction away from the axis (A) (e.g., the outer direction (+R direction) of the radial direction). The wearable electronic device (200) may be restricted from moving in a second direction (-X direction) by the flange portion (323). For example, the wearable electronic device (200) can be supported in a first direction (+X direction) by the flange portion (323).

[0187] According to one embodiment, with reference to FIG. 29, a polishing operation (S300) comprises: a second core member (330) including a second hole (H2) configured to accommodate a wearable electronic device (200); a second support member (340) configured to support the outer part (211) and including a portion (e.g., a support portion (342)) disposed between the outer part (211) of the wearable electronic device (200) and the second core member (330); and a masking member (350) disposed on the side of a first direction (+X direction) parallel to the axis (A) of the second core member (330), and including a third hole (H3) formed at a position corresponding to the second hole (H2) and having a diameter smaller than that of the second hole (H2), wherein the wearable electronic device (200) is seated on the second core member (330) and the wearable electronic device (200) is supported through the second support member (340). A supporting operation (S302) may be included. The insert assembly (IA) may be approached toward the first core member (320) from the first direction (+X direction) side of the first core member (320). The wearable electronic device (200) can be stably seated on the second manufacturing device (300) by being supported by the first core member (320) in the radial direction (+R direction) and the first direction (+X direction), and by being supported by the second support member (340) of the insert assembly (IA) in the radial direction (-R direction) and the second direction (-X direction). At least a portion of the wearable electronic device (200) may be exposed in the first direction (+X direction) through the third hole (H3). For example, an inner portion of the wearable electronic device (200) (e.g., inner portion (212) of FIG. 27) may be exposed toward the polishing member (370) through the third hole (H3).

[0188] According to one embodiment, with reference to FIG. 30, the polishing operation (S300) may include the operation (S303) of polishing an inner portion (212) of a wearable electronic device (200) by bringing a polishing member (370) toward a masking member (350) and a wearable electronic device (200). The polishing member (370) may approach the insert assembly (IA) and / or the wearable electronic device (200) from the first direction (+X direction) side of the insert assembly (IA). The polishing member (370) may rotate about a rotation axis (RA). The polishing member (370) may come into contact with the inner portion (212) of the wearable electronic device (200) and polish the inner portion (212). Since the part polished by the polishing member (370) in the wearable electronic device (200) can be limited to the inner part (212) of the wearable electronic device (200) by the masking member (350), partial polishing of the wearable electronic device (200) can be effectively performed.

[0190] Specifically, FIG. 31 is a perspective view illustrating an example of a first support member (570). FIG. 32 is an enlarged cross-sectional view along the line B-B' of FIG. 13, illustrating an example of a wearable electronic device (200) and a first support member (570).

[0191] Hereinafter, the detailed configuration of the first manufacturing device (500) according to one embodiment of the present disclosure may be the same as the detailed configuration of the first manufacturing device (400) described in relation to FIGS. 12 to 20.

[0192] According to one embodiment, each of the plurality of support portions (572) can support an outer portion (211) of a wearable electronic device (200). In each of the plurality of support portions (572), the outer portion (211) of the wearable electronic device (200) can be supported at one point by a first support member (570).

The support portion (575) may come into contact with the first portion (2111) of the wearable electronic device (200).

[0194] According to one embodiment, the contact surface (TP) at the point where the support member (575) and the outer part (211) of the wearable electronic device (200) (e.g., the first part (2111)) come into contact may be inclined such that the normal (NL) of the contact surface (TP) is oriented toward the axis (A) (e.g., the inner direction (-R direction) in the radial direction) and the second direction (-X direction). For example, the first support member (570) may be understood as supporting the wearable electronic device (200) downward in the direction toward the axis (A) (e.g., the inner direction (-R direction) in the radial direction) and the second direction (-X direction).

[0195] According to one embodiment, each of the plurality of support portions (572) may have a curved surface. For example, referring to FIG. 31, the support portion (575) may be connected to an area adjacent to the support portion (575) by a streamlined curved surface.

[0200] According to one embodiment, the wearable electronic device (200) may have a structure in which the central region of the outer portion (211) is convex. For example, the outer portion (211) of the wearable electronic device (200) may include a portion (e.g., a curved portion (2113)) in which the central region in the first direction (+X direction) and / or the second direction (-X direction) is convexly protruding in a direction away from the axis (A) (e.g., the outer direction (+R direction) among the radial directions). Each of the plurality of support portions (672) may support the wearable electronic device (200) by contacting the curved portion (2113) of the wearable electronic device (200).

[0201] According to one embodiment, each of the plurality of support portions (672) may include a support portion (675).

The support portion (675) may protrude from the support body portion (671) of the first support member (670) in a direction toward the axis (A) (e.g., inward direction (-R direction) in the radial direction). The support portion (675) may come into contact with the curved portion (2113) of the wearable electronic device (200).

[0202] According to one embodiment, the contact surface (TP) at the point where the support member (675) and the outer part (211) (e.g., the curved part (2113)) of the wearable electronic device (200) come into contact may be inclined such that the normal (NL) of the contact surface (TP) is oriented between the direction toward the axis (A) (e.g., the inner direction (-R direction) in the radial direction) and the second direction (-X direction). For example, the first support member (670) may be understood as supporting the wearable electronic device (200) downward in the direction toward the axis (A) (e.g., the inner direction (-R direction) in the radial direction) and the second direction (-X direction).

[0203] Ring-type wearable electronic devices are typically worn on a user's finger to detect the user's biometric information. Accordingly, the inner portion of the ring-type wearable electronic device that faces the user's skin can be formed from a light-transmitting epoxy material. This inner portion of the epoxy material is completed by injecting liquid epoxy molding liquid, cutting the gate portion into which the epoxy was injected using a CNC process, and polishing the final machined surface.

[0204] However, in conventional manufacturing apparatus and manufacturing method for manufacturing ring-type wearable electronic devices, there were limitations in ensuring uniform appearance quality of the wearable electronic device due to reasons such as indentation occurring on the exterior of the wearable electronic device by the jig of the manufacturing apparatus or tool marks remaining on the processed surface.

[0205] In addition, in a conventional manufacturing apparatus and method for manufacturing a ring-type wearable electronic device, there were limitations in precisely performing partial polishing of the inner part made of epoxy, such as peeling off the deposited surface of the outer part of the wearable electronic device, due to the problem that the outer part of the wearable electronic device made of metal came into contact with the polishing member during the polishing process.

[0206] In addition, in the manufacturing apparatus and manufacturing method for manufacturing a conventional ring-type wearable electronic device, the wearable electronic device is not stably supported by the manufacturing apparatus (or jig) during the CNC process, so there was a problem in which the outer part of the wearable electronic device made of metal was cut or the inner part of the wearable electronic device made of epoxy was overcut.

[0207] In addition, in conventional manufacturing apparatus and manufacturing method for manufacturing ring-type wearable electronic devices, there were limitations in securing production efficiency and automating the manufacturing process when precisely processing the exterior of the wearable electronic device.
