[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a finished product palletizing robot for rock tea processing, including a rotating base 1, a robotic arm 2 above the rotating base 1, a clamping seat 3 at the output end of the robotic arm 2, a transmission cavity 4 inside the clamping seat 3, four threaded rods 11 arranged in a ring at equal intervals inside the transmission cavity 4, each threaded rod 11 being threadedly connected to a moving block 12, one end of each moving block 12 extending to the outside of the transmission cavity 4, and an L-shaped clamping block 20 welded to the end of each moving block 12 outside the transmission cavity 4, a rotating cavity 15 inside the rotating base 1, a rotating shaft 16 rotatably arranged inside the rotating cavity 15, one end of the rotating shaft 16 extending to the outside of the rotating cavity 15, and the end of the rotating shaft 16 outside the rotating base 1 being connected to the robotic arm 2, and four guide rods 13 arranged in a ring at equal intervals welded to the outside of the transmission cavity 4, the guide rods 13 passing through the moving blocks 12, and the guide rods 13 slidingly engaging with the moving blocks 12.

[0025] The rotating base 1 is installed by bolts. The robotic arm 2 is started to move the clamping seat 3 to the upper end of the box. The first motor 5 is started to drive the first rotating rod 6 and the first bevel gear 7 to rotate, which in turn drives the four second bevel gears 9 and the second rotating rod 8 to rotate synchronously, so that the threaded rod 11 and the moving block 12 rotate. The guide rod 13 restricts the axial movement of the moving block 12, so that it is converted into horizontal movement, thereby driving the L-shaped clamping block 20 to clamp the box. The second motor 19 is started, and through the worm gear 18 and the worm wheel 17, the rotating shaft 16 and the robotic arm 2 are driven to rotate, so as to realize the rotating stacking of the box.

[0026] Please see Figure 2 , Figure 3 and Figure 5A first motor 5 is installed on one side inside the transmission cavity 4. The output end of the first motor 5 is connected to a first rotating rod 6 via a coupling. The power of the first motor 5 is directly and efficiently transmitted to the first rotating rod 6, reducing energy loss. A first bevel gear 7 is installed on the outer wall of the first rotating rod 6. A second rotating rod 8 is welded to one end of each threaded rod 11. A second bevel gear 9 is installed at one end of each second rotating rod 8, and the second bevel gear 9 meshes with the first bevel gear 7. Through the meshing of the first bevel gear 7 and the second bevel gear 9, the power transmission from the first rotating rod 6 to the four second rotating rods 8 is realized, and the four second rotating rods 8 can be ensured to rotate synchronously, thereby driving the four threaded rods 11 to work synchronously, improving the synchronicity and stability of clamping. A bearing 10 is installed on the outer wall of the second rotating rod 8. The inner wall of the bearing 10 is connected to the outer wall of the second rotating rod 8, and the outer wall of the bearing 10 is connected to the interior of the transmission cavity 4. The bearing 10 can reduce the frictional resistance of the second rotating rod 8 during rotation, ensuring smooth rotation and durability.

[0027] Please see Figure 4 A transmission worm gear 17 is provided on the outer wall of one end of the rotating shaft 16 inside the rotating cavity 15. A transmission worm 18 is rotatably provided at the rear end inside the rotating cavity 15, and the transmission worm 18 and the transmission worm gear 17 are connected by a worm gear transmission. The worm gear transmission can achieve smooth and reliable transmission from the transmission worm 18 to the transmission worm gear 17. The worm gear transmission has self-locking property, which can prevent the rotating shaft 16 and the robotic arm 2 from rotating unexpectedly when the second motor 19 stops working, thus enhancing the stability and safety of the equipment. A second motor 19 is provided on one side inside the rotating cavity 15, and the output end of the second motor 19 is connected to the transmission worm 18 through a coupling. The power of the second motor 19 is directly transmitted to the transmission worm 18, driving it to rotate, thereby realizing the rotation of the robotic arm 2 and the clamping seat 3, and completing the stacking of the box.

[0028] Please see Figure 1 and Figure 2 Three sets of equally spaced suction cups 14 are provided on one side of the clamping seat 3, and each set of suction cups 14 has three equally spaced suction cups. The equally spaced distribution of the suction cups 14 can ensure uniform adsorption on the surface of the box and improve the stability and reliability of adsorption.

[0029] Working Principle: In use, the rotating base 1 is installed with bolts. The mechanical arm 2 is activated to move the clamping seat 3 to the top of the box containing the finished rock tea. The first motor 5 is started, and it rotates the first rotating rod 6 via a coupling. The first rotating rod 6 drives the first bevel gear 7 to rotate synchronously. Since the first bevel gear 7 is meshed with four second bevel gears 9, the four second bevel gears 9 drive the second rotating rod 8 to rotate synchronously. The bearing 10 ensures the smooth rotation of the second rotating rod 8. The second rotating rod 8 drives the threaded rod 11 to rotate synchronously, and the threaded rod 11 drives the moving blocks 12 to rotate synchronously. Since the moving blocks 12 are all slidingly engaged with the guide rod 13, they are all subject to axial limitation. The rotation of the four moving blocks 12 is converted into opposite or opposite horizontal linear movements. The four moving blocks 12 move in opposite directions, causing the L-shaped clamping blocks 20 to clamp and fix the four sides of the box. At the same time, the suction cups 14 can adsorb the top of the box, improving stability and preventing damage to the finished rock tea inside. The second motor 19 is started, which rotates the transmission worm gear 18 through the coupling. The transmission worm gear 18 and the transmission worm wheel 17 are connected by worm gear transmission, which drives the transmission worm wheel 17 to rotate the rotating shaft 16. Since the rotating shaft 16 is connected to the robotic arm 2, it drives the robotic arm 2 to rotate, realizing the movement of the clamping seat 3 and the box. The worm gear transmission has self-locking properties, so the robotic arm 2 and the clamping seat 3 will not move or rotate unexpectedly under sudden impact or vibration, thus greatly enhancing the stability and safety of the equipment and ensuring the stability of the rock tea finished product stacking.
