[0001] The utility model relates to the technical field of piece-picking machines, in particular to a swing arm adjustment mechanism for a four-axis piece-picking machine. Background Art

[0002] A four-axis picker is an automated device primarily used for fast, accurate, and efficient pick-and-place operations on factory production lines. It typically consists of four independent electric servos or servo motors driving a swing-arm mechanism, enabling flexible grasping and release of objects. This structure can significantly improve production efficiency and reduce labor costs.

[0003] Existing four-axis pickup machines, such as the servo pickup machine disclosed in the Chinese utility model patent application number 202320656393.6, have a pickup arm assembly comprising a connecting rod rotatably connected to the machine platform and a rotating arm rotatably connected to the connecting rod. One end of the rotating arm is provided with a pickup gripper fixedly connected to it.

[0004] In view of the above-mentioned prior art, the inventor believes that the length of the rotating arm is fixed, which is not convenient for flexible adjustment according to the distance of the workpiece. Therefore, the present invention proposes a swing arm adjustment mechanism for a four-axis pickup machine to solve the above problem. Utility Model Content

The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0015] The following is combined with Figure 1-3 The specific implementation methods of the present utility model are further described in detail.

[0016] Depend on Figure 1-3The utility model provides a swing arm adjustment mechanism for a four-axis piece picking machine, including a piece picking machine main arm 10, a rotating motor 20 is fixedly installed on the head of the piece picking machine main arm 10, and the output shaft of the rotating motor 20 is connected to a mechanical gripper 40 through a rotating arm 30. When in use, the piece picking machine main arm 10 drives the mechanical gripper 40 to enter the work station and clamp the workpiece under the drive of the connecting rod mechanism, and then the rotating motor 20 drives the rotating arm 30 to rotate, the mechanical gripper 40 is released, and the workpiece is dropped. The above is the swing arm piece picking mechanism of the existing four-axis piece picking machine, which will not be elaborated here.

[0017] The swing arm length of the existing four-axis pickup machine is fixed, which is not convenient for adjustment according to the distance of the workpiece. In this embodiment, the rotating arm 30 includes a first telescopic rod 31 fixed to the output shaft of the rotating motor 20, a second telescopic rod 32 fixed to the mechanical gripper 40, and a connecting member 33 whose two ends are respectively slidably connected to the first telescopic rod 31 and the second telescopic rod 32. The first telescopic rod 32 and the second telescopic rod 32 are movably connected through the connecting member 33. The overall length of the swing arm can be adjusted by slidingly adjusting the position of the first telescopic rod 31 and the second telescopic rod 32 on the connecting member 33.

[0018] In some embodiments, the first telescopic rod 31 and the second telescopic rod 32 are both cylindrical structures, and both ends of the connecting member 33 are slidably inserted into the first telescopic rod 31 and the second telescopic rod 32 respectively.

[0019] In some embodiments, the connecting member 33 includes a first connecting member 331 and a second connecting member 332 that are slidably inserted into the first telescopic rod 31 and the second telescopic rod 32. A fine-adjustment mechanism 333 is provided between the first connecting member 331 and the second connecting member 332. When in use, the position of the first connecting member 331 in the first telescopic rod 31 and the position of the second connecting member 332 in the second telescopic rod 32 are adjusted by sliding, so that the length of the swing arm can be quickly and roughly adjusted. After the rough adjustment, the length of the connecting member 33 can be fine-tuned through the fine-adjustment mechanism 333, thereby achieving fine-adjustment of the length of the swing arm. The combination of the two makes it possible to adjust the length of the swing arm quickly and accurately.

[0020] The following is a specific embodiment of the fine-tuning mechanism 333:

[0021] The fine-tuning mechanism 333 includes a fine-tuning screw 3331 and a guide structure 3332. One end of the fine-tuning screw 3331 is rotatably connected to the first connecting member 331, and the other end of the fine-tuning screw 3331 is connected to the internal thread of the second connecting member 332. One end of the guide structure 332 is fixedly connected to the second connecting member 332, and the other end of the guide structure 332 is slidably connected to the first connecting member 331. The first connecting member 331 and the second connecting member 332 can slide to adjust the overall length under the guidance of the guide structure 3332. By rotating the fine-tuning screw 3331, the second connecting member 332 can be driven to slide on the first connecting member 331, thereby realizing fine-tuning of the length of the connecting member 33.

[0022] Specifically, the first connecting member 331 and the second connecting member 332 are provided with fixing grooves 334 along the length direction, and the first telescopic rod 31 and the second telescopic rod 32 are threadedly connected with fixing bolts 335. When in use, one end of the first connecting member 331 and the second connecting member 332 are fixed to the first telescopic rod 31 and the second telescopic rod 32 respectively through the fixing bolts 335 to achieve coarse adjustment of the swing arm length. However, by rotating the fine-tuning screw 3331 to drive the second connecting member 332 to slide on the first connecting member 331, the swing arm length can be finely adjusted by adjusting the length of the connecting member 33.

[0023] In order to facilitate manual rotation of the fine-tuning screw 331 , anti-slip grooves 3334 are provided on the surface of the fine-tuning screw 331 .

[0024] The present invention provides a swing arm adjustment mechanism for a four-axis parcel pickup machine. To better control the overall length of the swing arm, the swing arm is designed as a multi-part assembly, including a movable first telescopic rod 31 and a second telescopic rod 32. These two telescopic rods are connected by a connector 33. This connector 33 can move between the two telescopic rods, allowing the swing arm length to be roughly adjusted over a wide range. In addition, the connector 33 includes a fine-tuning mechanism 333, which allows for more precise adjustment of the length of the connector 33. This design allows for quick and accurate adjustment of the swing arm length, greatly improving the efficiency and performance of the four-axis parcel pickup machine.
