Technology Field
[0001] The present invention relates to a mechanism for centering and fixing a part, and more specifically, to a mechanism for centering and fixing a part provided in a transfer device that is installed in the transfer device and centeres and fixes a part being transferred. Background Technology
[0002] Generally, a component supply device refers to an automated machine that supplies components during product manufacturing. These component supply devices have undergone continuous development, and supply is being carried out in various forms. In particular, because the components of electronic products are small in volume (or size), meticulous attention must be paid to their supply, and in order to supply them directly to the assembly process, each component must be supplied in the correct position and orientation.
[0003] Therefore, it is desirable for the part supply device to ensure that the subsequent process is executed more quickly and efficiently by supplying parts in the correct position and orientation for accurately operating subsequent tasks, such as robotic operations. In such part transfer processes, if the supplied parts are provided in an incorrect orientation rather than the correct one, the subsequent process may not proceed accurately, potentially leading to problems such as defective assembly.
[0004] FIG. 1 illustrates an exemplary wireless earphone component as an example of a part. As shown in FIG. 1, the wireless earphone component is provided in a form having one or more curved sections (11) and straight sections (13) along the edges. While it may be relatively easy to supply a component in a shape such as a circle or a square in an accurate position and orientation, it is not easy to fix and supply an irregularly shaped component as shown in FIG. 1 in an accurate position and orientation, and in particular, it was not easy to transport multiple components at once. In addition, there were problems such as deformation of the component due to increased gripping force in order to supply it in an accurate position and orientation. Prior art literature

[0078] The angle between the inclined portion (1513) and the supporting inner surface portion (1511) is formed to be greater than 90° and less than 180°. Since the angle between the inclined portion (1513) and the supporting inner surface portion (1511) is an obtuse angle greater than 90°, it is possible to stably center and fix the outer surface of the part (10) in an arc shape rather than a straight line.
