Common rotary conveyors generally include a rotating platform, a carrier, and multiple workpiece positioning fixtures. The carrier is connected to the output end of the rotating platform, and the workpiece positioning fixtures are spaced circumferentially on the carrier. In use, the carrier rotates sequentially with the rotating platform to each workstation, enabling workpiece loading, processing, and unloading operations. However, this rotary conveyor is primarily suitable for transporting single workpieces; when assembling multiple workpieces, multiple conveyor systems are usually required, resulting in a large footprint and high manufacturing costs for the entire assembly equipment. Summary of the Invention

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 6 As shown, a rotary conveying device includes a base 1, on which a turntable 2 is rotatably mounted. Multiple intermediate transfer platforms 3 are rotatably mounted on the top surface of the turntable 2 at intervals along a circumferential direction. One or multiple intermediate positioning platforms 4 are eccentrically mounted on the top surface of each intermediate transfer platform 3, or spaced apart along a circumferential direction. Multiple positioning platform groups are mounted on the top surface of the turntable 2, each group including multiple first positioning platforms 51, multiple second positioning platforms 52, and multiple third positioning platforms 53. Each first positioning platform 51 and each second positioning platform 52 is alternately arranged circumferentially between two adjacent intermediate transfer platforms 3, and each third positioning platform 53 is located between the same two intermediate transfer platforms 3 as each first positioning platform 51. A turntable drive mechanism for driving the turntable 2 to rotate is mounted on the base 1. An intermediate transfer platform drive mechanism 7 for driving all intermediate transfer platforms 3 to rotate together is mounted on the turntable 2.

[0021] Specifically, in this embodiment, the turntable drive mechanism may include an internal gear ring, an internal gear meshing with the internal gear ring, and a motor driving the internal gear to rotate. The turntable 2 is rotatably connected to the base 1 via roller bearings, and the internal gear ring is coaxially connected to the turntable 2. In use, the motor drives the internal gear to rotate, and the meshing transmission between the internal gear and the internal gear ring drives the turntable 2 to rotate. Alternatively, a hollow rotary platform can be used as the turntable drive mechanism to drive the turntable 2 to perform high-precision rotational motion.

[0022] In this embodiment, the top surface of the first positioning platform 51 is provided with a first positioning groove 511; the top surface of the second positioning platform 52 is provided with a second positioning groove 521; and the top surface of the third positioning platform 53 is provided with a set of third positioning grooves 531. Further, a protrusion 522 protrudes from the inner side of the second positioning groove 521 to limit the positioning of the second workpiece 20 located within the second positioning groove 521. In this embodiment, the first workpiece 10 is cylindrical, therefore the first positioning groove 511 is a circular groove; the second workpiece 20 is a gear, therefore a protrusion 522 with a triangular cross-section is inserted into a tooth groove of the second workpiece 20 to achieve positioning of the second workpiece 20. The third workpiece is a shell workpiece with multiple cylindrical protrusions, therefore multiple circular third positioning grooves 531 are provided on the third positioning platform 53.

[0023] In this embodiment, a central platform 21 is coaxially connected to the top surface of the turntable 2; each intermediate turntable 3 is distributed around the central platform 21. The central platform 21 rotates synchronously with the turntable 2. By setting the central platform 21, the placement space can be expanded to accommodate more workpieces, workpiece fixtures, etc.

[0024] In this embodiment, a transfer positioning groove 41 is provided on the top surface of the transfer positioning platform 4 for positioning and placing the transfer parts during the assembly process.

[0025] In this embodiment, the turntable drive mechanism 7 includes a gear ring 71 coaxially rotatably connected to the bottom surface of the turntable 2. The gear ring 71 meshes with a drive gear and at least three driven gears 72. The drive gear is connected to a motor that drives its rotation. Each driven gear 72 is coaxially connected to the corresponding turntable 3 through a connecting shaft 6. The connecting shaft 6 is rotatably mounted on the turntable 2.

[0026] In use, the motor drives the drive gear to rotate. Through the meshing transmission between the drive gear and the gear ring 71 and the meshing transmission between the gear ring 71 and each driven gear 72, each transfer platform 3 rotates together relative to the turntable 2, thereby realizing the position switching of each transfer positioning platform 4 on the transfer platform 3.

[0027] It should be noted that the structures of the various transfer positioning platforms 4 on the transfer platform 3 can be the same or different.

[0028] The present invention discloses a rotary conveying device. In use, the turntable is driven by the turntable drive mechanism to circulate between the loading and unloading station, the first assembly station and the second assembly station in sequence. When the turntable 2 rotates to the loading and unloading station, it removes the assembled product components and places the first workpiece 10, the second workpiece 20 and the third workpiece 30 to be assembled on the first positioning platform 51, the second positioning platform 52 and the third positioning platform 53 respectively.

[0029] When the first workpiece 10 rotates with the turntable 2 to the first assembly station, the first workpiece 10 is removed. When the second workpiece 20 rotates with the turntable 2 to the first assembly station, the second workpiece 20 is removed, and the second workpiece 20 is pressed together with the first workpiece 10 using a primary pressing mechanism. The first workpiece 10 and the second workpiece 20, after pressing, are placed on the transfer table 3 as primary transfer parts. When the third workpiece 30 rotates with the turntable 2 to the second assembly station, the third workpiece 30 is removed. When the primary transfer part rotates with the turntable 2 to the second assembly station, the primary transfer part is removed, and the primary transfer part is pressed together with the third workpiece 30 using a secondary pressing mechanism. The transfer table drive mechanism 7 drives the transfer table 3 to rotate, switching the position of the transfer positioning platform 4. The third workpiece 30, after pressing, and the primary transfer part are placed on the switched transfer positioning platform 4 as secondary transfer parts, thereby completing the assembly of the product components.

[0030] The rotary conveyor of this invention enables the simultaneous conveying of multiple different workpieces, which helps to improve conveying efficiency, reduce equipment space occupation, and lower manufacturing costs.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
