[0048] Detailed description and technical content of the present application will be explained as follows in conjunction with the drawings. However, the drawings are only used for illustration and are not used to limit the present application.

[0049] The application provides a positioning turntable of electronic components, which is mainly used for carrying electronic components A (such as passive components like resistors or inductors) with metal pins in a detection process, but is not limited to this. Please refer to Figures 1 to 5 As shown in the figure, the positioning turntable 1 mainly comprises a first disc body 10 and a second disc body 20.

[0050] In this embodiment, the first disc body 10 can be a metal disc made of steel or aluminum alloy, but the application is not limited to this, for example, the first disc body 10 can also be a plastic disc made by plastic injection or 3D printing (Additive Manufacturing, AM). The first disc body 10 has a top surface 11 and a central axis 12, and the periphery of the first disc body 10 is provided with a plurality of (at least two) limiting structures 13 arranged around the central axis 12 and spaced apart. Each limiting structure 13 comprises a first limiting groove 131 and a second limiting groove 132, and an included angle θ is formed between the center line of the first limiting groove 131 and the center line of the second limiting groove 132, so that the electronic component A corresponding to each limiting structure 13 can have two directional limiting positions. The first limiting groove 131 is rectangular and extends from the periphery of the first disc body 10 towards the central axis 12, and the shape of the second limiting groove 132 is the same as that of the first limiting groove 131. In this embodiment, the angle of the included angle θ is between 30° and 150°. Preferably, the angle of the included angle θ is between 45° and 135°. Best of all, the angle of the included angle θ is 90°, that is, the first limiting groove 131 and the second limiting groove 132 are perpendicular to each other to form a cross shape. However, the application is not limited to this, and the designer can adjust the angle of the included angle θ between the two according to different needs. In addition, the first disc body 10 is recessed with a plurality of grooves 14 on the top surface 11, and each groove 14 is respectively connected to each corresponding limiting structure 13.

[0051] In this embodiment, the second disc 20 can be a metal disc made of steel or aluminum alloy, but the present application is not limited thereto. For example, the second disc 20 can also be a plastic disc made by injection molding or 3D printing (Additive Manufacturing, AM). The second disc 20 has a shape corresponding to that of the first disc 10, and is connected to the first disc 10. The second disc 20 has a bottom surface 21 attached to the top surface 11 of the first disc 10. The bottom surface 21 of the second disc 20 and the grooves 14 together form a plurality of air passages 15, and the grooves 14 are connected between the first limiting groove 131 and the second limiting groove 132 of the corresponding limiting structure 13, so that the electronic component A can communicate with the air passages 15 regardless of whether it is located in the first limiting groove 131 or the second limiting groove 132. Preferably, the second disc 20 can also be recessed with a plurality of grooves (not shown in the figure) corresponding to the first disc 10, so that the grooves of the second disc 20 and the grooves 14 of the first disc 10 together form the aforementioned air passages 15. The periphery of the second disc 20 is provided with a plurality of accommodating structures 22 corresponding to the positions of the limiting structures 13. Each accommodating structure 22 includes a first accommodating groove 221 and a second accommodating groove 222, and the shapes of the first accommodating groove 221 and the second accommodating groove 222 are both rectangular corresponding to the first limiting groove 131 and the second limiting groove 132.

[0052] It is worth noting that the first disc 10 and the second disc 20 of the positioning turntable 1 of the present application can be two-piece or one-piece, and the present application does not limit this. Specifically, the first disc 10 and the second disc 20 of the two-piece positioning turntable 1 are independently manufactured and molded, and then combined and fixed by welding, melting, bonding, locking, riveting, clamping or other means; and the first disc 10 and the second disc 20 of the one-piece positioning turntable 1 are directly integrally molded, that is, they are molded together by the same process (such as molding, 3D printing, etc.), so the one-piece positioning turntable 1 does not have a top surface 11 and a bottom surface 21 of the joint surface. However, whether it is one-piece, two-piece or more pieces combined, as long as it has the structure of the features of the present application and achieves the same effect, it should be within the scope of protection of the present application.

[0053] Further explanation, please refer to Figure 1The second disc 20 is provided with a plurality of air extraction holes 23 at the end of each air passage 15 away from the limiting structure 13, and each air extraction hole 23 is connected to the corresponding air passage 15. By vacuumizing each air extraction hole 23, each air passage 15 can generate suction force to attract the corresponding limiting structure 13, thereby attracting the electronic component A in the limiting structure 13 to a suspended state, so as to facilitate the detection mechanism to detect. In addition, the present application does not limit the vacuumizing method of the air extraction hole 23. For example, the air extraction hole 23 can be respectively provided with a gas pipe joint (not shown in the figure), or the air extraction hole 23 can be collectively covered by a cover in a large suction nozzle (not shown in the figure), as long as it can effectively vacuumize and generate suction force.

[0054] Please refer to Figure 2 and Figure 3 , the length of the first limiting groove 131 is greater than the length of the first displacement groove 221, and the length of the second limiting groove 132 is greater than the length of the second displacement groove 222, so that the bottom of the first displacement groove 221 can be used as the axial limit of the first limiting groove 131, and the bottom of the second displacement groove 222 can be used as the axial limit of the second limiting groove 132, so that the electronic component A in the first limiting groove 131 or the second limiting groove 132 cannot enter the first displacement groove 221 or the second displacement groove 222 upward. In addition, the lower part of the first limiting groove 131 and the second limiting groove 132 is respectively recessed with a plurality of guide surfaces 133, each guide surface 133 extends obliquely away from the top surface 11 to form a trapezoidal space (not labeled in the figure) together, thereby serving as a guide structure when the electronic component A rises. However, the present application is not limited thereto, for example, the guide surface 133 can also be an arc surface.

[0055] Please refer to Figure 6 and Figure 7 , which are two use states of the electronic component A adsorbed in the same limiting structure 13, in order to meet the detection needs in different directions. Figure 6 The electronic component A in is located in the first limiting groove 131 towards the central axis 12 of the second disc 20, which cannot move longitudinally and laterally due to the limitation of the first limiting groove 131, and is adsorbed and fixed in a suspended state by the suction force of the air passage 15. Figure 7 The electronic component A in is located in the second limiting groove 132, which cannot move longitudinally and laterally due to the limitation of the second limiting groove 132, and is adsorbed and fixed in a suspended state by the suction force of the air passage 15; it is worth noting that Figure 7 The electronic component A in does not directly contact the air passage 15, but since the electronic component A has a small volume and a very light weight (about 0.1g-30g), as long as the suction force reaches a certain strength, the electronic component A can be adsorbed and fixed in the second limiting groove 132.

[0056] Referring to Figures 8 to 10 Fig. 1 is a schematic diagram of the use of the detection mechanism according to the present application. The detection mechanism comprises at least one suction nozzle B and at least one detection seat C corresponding thereto. The suction nozzle B is located above the positioning turntable 1, and the detection seat C is located below the positioning turntable 1. The detection process of the electronic component A on the positioning turntable 1 is briefly described as follows:

[0057] First, referring to Figure 9 , the electronic component A to be detected is first positioned by the limiting structure 13 to achieve the positioning effect, and then is adsorbed in the limiting structure 13 by the vacuum suction force formed by the air passage 15 to maintain a suspended state.

[0058] Next, referring to Figure 10 , the suction nozzle B moves downward to the surface of the electronic component A, and after the suction nozzle B adsorbs the electronic component A, it continues to move downward to make the electronic component A separate from the positioning turntable 1. It is worth noting that the limiting structure 22 can avoid interference between the suction nozzle B and the positioning turntable 1, and since the electronic component A has been positioned by the limiting structure 13 of the positioning turntable 1, the suction nozzle B can directly move vertically downward to the positioning, so that the electronic component A can be detected by the detection seat C.

[0059] Finally, after the detection is completed, the suction nozzle B continues to adsorb the electronic component A and lifts upward, thereby moving the electronic component A into the limiting structure 13, until the electronic component A is stopped by the bottom stop of the limiting structure 22 and cannot continue to rise, and is adsorbed and fixed in the limiting structure 13 by the vacuum suction force of the air passage 15. In addition, during the lifting process of the suction nozzle B, if there is a slight deviation due to suction force, gravity or other external factors, it can be corrected by the guide surface 133 of the limiting structure 13 until it is adsorbed and fixed by the vacuum suction force of the air passage 15 after positioning.

[0060] It is worth noting that the suction nozzle B of the detection mechanism can rotate corresponding to the detection direction required by the electronic component A, that is, the suction nozzle B can rotate at different angles to adsorb the electronic component A located in the first limiting groove 131 or the second limiting groove 132. In this way, when the electronic component A needs to be detected in different directions, the operator only needs to replace the detection seat C, so that the same positioning turntable 1 can be shared to achieve better generalization rate, while reducing the manufacturing cost, replacement time and storage space of the positioning turntable 1.

[0061] In summary, the present application has industrial practicality, novelty and inventiveness, and fully meets the requirements of patent application, and is now applied according to the Patent Law. Of course, the present application can also have other various embodiments, and those skilled in the art can evolve various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application, but these corresponding changes and modifications should all belong to the protection scope of the patent application of the present application.
