[0003] Existing robotic arms have some shortcomings in practical applications. Most existing adsorption devices are fixed designs, which are difficult to adapt to materials of different specifications, resulting in unstable gripping, easy displacement, and frequent production line shutdowns. Utility Model Content

[0004] The purpose of this invention is to provide a robotic arm for feeding materials onto a stirring rod, in order to solve the problem that most existing adsorption devices are of a fixed design.

[0005] To achieve the above objectives, the present invention employs the following technology: a robotic arm for feeding a stirring rod, comprising a frame, wherein the frame is equipped with a conveying assembly capable of removing the stirring rod from the injection molding machine, and an adjusting assembly capable of adjusting the feeding position of the stirring rod; The conveying assembly includes a crossbeam and a motor respectively mounted on the frame.

Electric suction cups are symmetrically mounted at the bottom of the mounting frame, and the mounting frame is also equipped with a rotating component that can adjust the position of the electric suction cups.

[0006] As a further description of the above technical solution: the rotating component includes motor two and motor three respectively mounted on the frame and mounting bracket. The bottom end of the mounting bracket is rotatably connected to a positive and negative threaded rod, and the two sides of the positive and negative threaded rod are respectively threaded with a movable plate.

[0007] As a further description of the above technical solution: the mounting bracket is rotatably mounted on the frame via a connecting rod, and one end of the connecting rod is fixedly connected to the output end of motor two, one end of the positive and negative threaded rod is fixedly connected to the output end of motor three, and the electric suction cups are symmetrically mounted on the moving plate.

[0008] As a further description of the above technical solution: the adjustment assembly includes a guide rail and a rack disposed on the crossbeam, a slide is mounted on the guide rail, a support plate is fixedly connected to one side of the slide, and gear one and motor four are respectively disposed on the support plate.

[0009] As a further description of the above technical solution: the first gear is rotatably mounted on the support plate, and the first gear is fixedly mounted on the output end of the fourth motor, and the first gear meshes with the rack.

[0010] As a further description of the above technical solution: the carriage is also equipped with a lifting component; The lifting component includes several toothed grooves formed on the lifting frame, and gear two is set inside the slide frame via a rotating rod.

[0011] As a further description of the above technical solution: the lifting frame is slidably mounted on the slide, the tooth groove meshes with the gear two, and the rotating rod extends to one end of the slide and is fixedly connected to the output end of the motor five.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The conveying assembly works in concert with components such as the crossbeam, motor one, and lifting frame.

[0015] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1 - Figure 6 This embodiment provides a robotic arm for feeding a stirring rod, including a frame 10, a conveying assembly 20 that can remove the stirring rod from an injection molding machine, the injection molding machine being used to injection mold the stirring rod, and an adjustment assembly 30 that can adjust the feeding position of the stirring rod. The conveying assembly 20 includes a crossbeam 21 and a motor 22 respectively mounted on the frame 10. The crossbeam 21 is rotatably mounted on the frame 10, and one end of the crossbeam 21 is fixedly mounted on the output end of the motor 22. The motor 22 can drive the crossbeam 21 to rotate, so that after the electric suction cup 26 removes the stirring rod from the injection molding machine, the rotating crossbeam 21 moves the stirring rod to the top of the welding device. The lifting frame 23 is symmetrically arranged on the crossbeam 21, and the mounting frame 24 is mounted on the lifting frame 23 through the frame 25. The lifting frame 23 can drive the mounting frame 24 and the frame 25 to move. The bottom end of the mounting frame 24 is symmetrically provided with electric suction cups 26. The electric suction cups 26 are existing technology. The electric suction cups 26 can play a role in adsorbing the stirring rod, thereby moving the stirring rod. The mounting frame 24 is also equipped with a rotating component 27 that can adjust the position of the electric suction cups 26.

[0017] Reference Figure 3 - Figure 4Specifically, in order to adjust the adsorption position of the electric suction cup 26, a rotating component 27 is provided. The rotating component 27 includes a second motor 271 and a third motor 272 respectively mounted on the frame 25 and the mounting bracket 24. The bottom end of the mounting bracket 24 is rotatably connected to a positive and negative threaded rod 273. The two sides of the positive and negative threaded rod 273 are respectively threaded with moving plates 274. When the positive and negative threaded rod 273 rotates in the forward and reverse directions, the two moving plates 274 can move synchronously towards the opposite or opposite sides.

[0018] In more detail, the mounting bracket 24 is rotatably mounted on the frame 25 via a connecting rod, and one end of the connecting rod is fixedly connected to the output end of the second motor 271. The second motor 271 can drive the connecting rod to rotate, which in turn causes the mounting bracket 24 to rotate, thereby driving the electric suction cup 26 to adjust the suction angle. One end of the positive and negative threaded rod 273 is fixedly connected to the output end of the third motor 272, which can drive the positive and negative threaded rod 273 to rotate. The electric suction cups 26 are symmetrically mounted on the moving plate 274. By starting the third motor 272, the third motor 272 can drive the positive and negative threaded rods 273 to rotate, thereby enabling the two moving plates 274 to move synchronously towards opposite or opposite directions. While the moving plates 274 are moving, the electric suction cups 26 on both sides will also move, thereby adjusting the distance between the two sets of electric suction cups 26.

[0019] Reference Figure 4 Specifically, in order to enable the electric suction cup 26 to move laterally, an adjustment component 30 is provided. The adjustment component 30 includes a guide rail 31 and a rack 32 set on the crossbeam 21. The slide 33 is slidably mounted on the guide rail 31. The slide 33 can remain stable while moving through the guide rail 31. A support plate is fixedly connected to one side of the slide 33. Gear 1 34 and motor 4 35 are respectively set on the support plate.

[0020] In more detail, gear 34 is rotatably mounted on the support plate and fixedly mounted on the output end of motor 35. Motor 35 can drive gear 34 to start rotating. Gear 34 meshes with rack 32. When the position of electric suction cup 26 needs to be adjusted laterally, motor 35 is started, which drives gear 34 to start rotating. Through meshing with rack 32, gear 34 can drive slide 33 to move while rotating, thereby driving the lifting frame 23 and the electric suction cup 26 at the bottom to make lateral adjustments.

[0021] Reference Figure 5 Specifically, in order to enable the electric suction cup 26 to be raised and lowered so as to absorb the stirring rod and feed the material, the adjustment component 30 is set and the slide 33 is also equipped with a lifting component 36. The lifting component 36 includes several toothed grooves 361 formed on the lifting frame 23. Gear 2 362 is set inside the slide 33 via a rotating rod 363. Gear 2 362 is fixedly installed on the rotating rod 363, and the rotating rod 363 enables gear 2 362 to rotate. Motor 5 364 is fixedly installed on one side of the slide 33.

[0022] In more detail, the lifting frame 23 is slidably mounted on the slide 33, the toothed groove 361 meshes with the second gear 362, and the rotating rod 363 extends to one end of the slide 33 and is fixedly connected to the output end of the fifth motor 364. When feeding the stirring rod, the lifting frame 23 and the electric suction cup 26 at the bottom are rotated to the top of the injection molding machine by the cross frame 21. Then, the fifth motor 364 is started, and the rotating rod 363 is driven by the fifth motor 364 to start rotating the second gear 362. Through meshing with the toothed groove 361, the lifting frame 23 begins to descend, so that the electric suction cup 26 can descend to the position of the injection molding machine to pick up the stirring rod. Then, the second gear 362 is rotated in the opposite direction, so that the lifting frame 23 drives the electric suction cup 26 and the picked-up stirring rod to rise. Then, the lifting frame 23 and the electric suction cup 26 at the bottom are rotated to the top of the welding device by the cross frame 21 again. Then, the rotation of the second gear 362 causes the lifting frame 23 to descend, so that the stirring rod is placed on the welding device to weld with the film. Welding the film onto the stirring rod is primarily to improve the fatigue resistance and structural strength of the welded area, preventing localized stress concentration or crack propagation; it also protects the welded area from chemical corrosion or mechanical wear; furthermore, it provides leak-proof and sealing functions to the welded area, ensuring the reliability and durability of the stirring rod in the working environment.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
