With the development of industrial automation technology, it is particularly important to develop a device that can efficiently and stably grip and transport such items.
[0003] Most existing gripping and transporting devices use fixed gripping mechanisms, and control the gripping claws of the mechanical arm through cylinders or motors to achieve gripping and move the objects to the destination.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
[0033] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0034] The following is a further detailed description of a clamping and transferring device and its application according to the present invention in conjunction with the accompanying drawings.
[0035] Combined with Figure 1-6 The specific implementation process of a clamping and transporting device and its application of the present invention is as follows:
[0036] A clamping and transporting device comprises a U-shaped support frame 1, a rotating mechanism 2, a suspension frame 3 and a clamping mechanism 4. The rotating mechanism 2 and the clamping mechanism 4 are both connected to a controller, and an automated process is realized through the controller.
[0037] The rotating mechanism 2 includes a rotating drive motor 5 and a rotating frame 6. The rotating drive motor 5 is fixed on the support frame 1. The rotating frame 6 is connected to the power output end of the rotating drive motor 5 and is driven to flip. For ease of use, a speed change gear box 13 can be added to the power output end of the rotating drive motor 5. The rotating speed is adjusted by the speed change gear. The power output structure of the speed change gear box 13 is connected to the rotating shaft 24 of the rotating frame 6, thereby driving the rotating frame 6 to rotate; in this way, by controlling the rotating drive motor 5, the rotation of the rotating frame 6 can be realized, thereby driving the suspension frame 3 to move and adjust the working position of the clamping mechanism 4.
[0038] The suspension frame 3 is arranged in the rotating frame 6 and is rotatably connected to both sides thereof. The clamping mechanism 4 is fixed to the end of the suspension frame 3, and several groups can be symmetrically arranged about the suspension frame 3, and specifically one group can be symmetrically arranged about the center, so as to clamp the two ends of the beaded product. This design allows the suspension frame 3 to rotate relative to the rotating frame 6, and the self-gravity balance achieved by the symmetrical arrangement of the clamping mechanism 4 allows the clamping mechanism 4 to always remain parallel to the horizontal plane during the rotation of the rotating frame 6.
[0039] The clamping mechanism 4 includes a connecting frame plate 7, a clamp mounting plate 8, a clamp 9 and a clamping drive assembly. The connecting frame plate 7 is fixed to the end of the suspension frame 3 by bolts, the upper end of the clamp mounting plate 8 is fixed to the lower part of the connecting frame plate 7, and the clamp 9 is arranged on the clamp mounting plate 8 and connected to the clamping drive assembly. Under the drive of the clamping drive assembly, the clamp 9 can clamp or release the object.
[0040] The clamping drive assembly includes a clamp driving motor 10, an eccentric wheel 11, and a clamp push plate 12. The power output end of the clamp driving motor 10 is connected to the gear box 13, and the output end of the gear box 13 is connected to the eccentric wheel 11. A cylindrical moving block 14 is provided on one side of the eccentric wheel 11, and the moving block 14 is fixed on the clamp push plate 12. When the clamp driving motor 10 is working, the gear box 13 drives the eccentric wheel 11 to rotate, thereby driving the clamp push plate 12 to move, and pushing the clamp 9 to clamp or release the object.
[0041] The clamp includes a left clamp body 15, a right clamp body 16 and a reset torsion spring 17. The middle parts of the left clamp body 15 and the right clamp body 16 are rotatably connected to the clamp mounting plate 8 through a rotating shaft, and the reset torsion spring 17 is arranged between the left clamp body 15 and the right clamp body 16, and its two ends are respectively connected to the left clamp body 15 and the right clamp body 16. Under the action of the reset torsion spring 17, the left clamp body 15 and the right clamp body 16 can be automatically reset to achieve the clamping and release of the object.
[0042] In order to further improve the stability of clamping, the top of the right clamp body 16 is higher than the left clamp body 15, and a downward extending push piece is provided at the lower end of the clamp push plate 12, which can contact the top of the right clamp body 16 to drive the right clamp body 16 to separate from the left clamp body 15, so as to separate the left clamp body 15 from the right clamp body 16. When the clamp push plate 12 drives the push piece to separate from the right clamp body 16, the left clamp body 15 and the right clamp body 16 are automatically closed and clamped under the drive of the reset torsion spring 17. This design makes the clamp more stable when clamping objects and is not easy to fall off.
[0043] In addition, a clamp mounting hole 18 is provided on one side of the lower part of the right clamp body 16 close to the left clamp body 15, and a removable extended clamp 19 is provided in the clamp mounting hole 18. Since the right clamp body 16 as a whole is partially moved upward relative to the left clamp body 15, the lower end of the right clamp body 16 is lengthened by the extended clamp 19 so that it can cooperate with the left clamp body 15 for clamping.
[0044] In order to increase the clamping force and stability of the clamp 9, mutually meshing protruding teeth 20 are provided in the middle of the left clamp body 15 and the right clamp body 16. In this way, when the clamp 9 clamps an article, the protruding teeth 20 can mesh with each other to improve the stability of the clamping.
[0045] In order to further improve the stability of the rotating mechanism 2, a stabilizing structure is provided on the side of the rotating frame 6 opposite to the rotating drive motor 5, and the stabilizing structure includes a first pulley 21, a second pulley 22, and a belt 23 connecting the two. The first pulley 21 is arranged outside the rotating frame 6 and is coaxially connected to the rotating shaft 24 of the rotating frame 6, and the second pulley 22 is arranged on the same side as the first pulley 21 and is coaxially connected to the suspension frame 3. This design can effectively prevent the rotating frame 6 from shaking during rotation and improve the stability of the entire device.
[0046] In order to limit the rotation range of the rotating frame 6, a rotation limiter 25 is provided at the end of the rotating shaft 24 of the rotating frame 6. By adjusting the position of the rotation limiter 25, the rotation angle of the rotating frame 6 can be controlled to avoid damage caused by excessive rotation. Specifically, in the present application, the rotating frame 6 is limited to rotate within the range of 0-180°.
[0047] Finally, the clamping and transporting device of the present invention can be applied to a bead stringing machine. After the bead stringing is completed, the clamping mechanisms 4 on both sides of the suspension frame 3 clamp the two ends of the beads respectively, clamp them from the bead stringing table and transport them to the workbench of the next process, or place them in a storage box.
[0048] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
