Technical Field
[0001] This invention relates to the field of equipment and machinery technology, and specifically to a robotic arm that facilitates handling. Background Technology
[0002] Currently, industrial handling robots often face problems such as insufficient three-dimensional spatial positioning accuracy, easy detachment during handling, and limited compatibility with specific specifications when processing slender rods such as drying racks. Traditional robots mostly adopt single-axis rotation or fixed-angle designs, making it difficult to achieve precise angle control and coordinated vertical lifting of the rods during handling, which can easily lead to deviations during placement. At the same time, the fixing methods between the rods and the robot often rely on friction or simple latches, which are prone to slipping and detachment under movement, vibration, or heavy load scenarios, affecting operational stability and safety.
[0003] To address the aforementioned issues, this invention proposes a robotic arm with a double-layer rotating connecting shaft structure. Through a separate motion mode of the inner and outer shafts, combined with the meshing of gear slots and transmission gears, it achieves precise angle control of the outer shaft's fixation and the inner shaft's rotation. This, coupled with the vertical lifting capability of a telescopic cylinder, forms a precise positioning and coordinated motion capability within three-dimensional space. Furthermore, the robotic arm employs a pointed fixing tooth design, using the pointed tip to guide the drying rod to automatically slide into the bottom of the teeth, forming a mechanical lock, effectively preventing slippage and detachment during handling. Simultaneously, the adjustable width of the robotic arm and the number of fixing teeth allow it to adapt to different specifications of drying rod arrays, improving the equipment's versatility.

This invention features a rotating connecting shaft with a double-layered inner and outer shaft structure. The meshing of gear slots and transmission gears enables a separate motion mode where the outer shaft is fixed and the inner shaft rotates. A rotating motor allows for precise angle control, which, combined with the vertical lifting motion of a telescopic cylinder, creates precise positioning capabilities in three-dimensional space, meeting the angle adjustment and precise placement requirements of the drying racks during transport.

[0019] Please see Figure 1-3 The present invention provides a technical solution: The present invention provides a convenient handling robot, comprising a robot body 1, a rotating connecting shaft 4, a rotating motor 5, and a telescopic cylinder 6, characterized in that: the rotating connecting shaft 4 is provided at the upper end of the robot body 1, the telescopic cylinder 6 is provided at the upper end of the rotating connecting shaft 4, the rotating motor 5 is provided next to the telescopic cylinder 6, and the connecting base 7 is provided at the upper end of the telescopic cylinder 6; The rotating connecting shaft 4 includes an inner shaft 401, a gear groove 402, and an outer shaft 403. The gear groove 402 is provided on the outer side of the upper end face of the inner shaft 401, and the outer shaft 403 is provided outside the inner shaft 401. The lower end face of the outer shaft 403 is connected to the robot body 1, and the upper end face of the outer shaft 403 is connected to the fixed rotating motor 5. The telescopic arm of the telescopic cylinder 6 is connected in the inner shaft 401.
[0020] In this embodiment, the robot body 1 has an opening on its side, and a fixing tooth 2 is provided at the lower end of the opening inside the robot body 1.
[0021] In this embodiment, the front end of the rotating motor 5 meshes with the gear groove 402 through the transmission gear 9, and the rotation of the rotating motor 5 causes the outer shaft 403 and the inner shaft 401 to move relative to each other through the movement of the transmission gear 9 and the gear groove 402.
[0022] In this embodiment, the rotating motor 5 is connected to an external control system via a wire, and the telescopic cylinder 6 is externally controlled to extend and retract.
[0023] In this embodiment, a connecting post 8 is provided between the outer shaft 403 and the robot body 1.
[0024] In this embodiment, the connecting base 7 is provided with connecting threaded holes 10 at its four corners, and the connecting base 7 is connected to an external movable structure through the connecting threaded holes 10.
[0025] On the other hand, the present invention provides a working process for a robotic arm, characterized by including the following steps: S1: The gap of the main body 1 of the robotic arm is inserted into the gap between the drying rods of the persimmon strips, and the pointed structure of the fixed teeth 2 makes each drying rod slide into the bottom of the pointed structure. S2: The telescopic cylinder 6 causes the telescopic column to retract, which in turn lifts the main body of the robotic arm 1 and the drying pole of the dried persimmon strips upward; S3: The external moving structure brings the robot arm body 1 to the designated position; S4: Power is supplied to the rotating motor 5 according to the placement of the position. The rotating motor 5 rotates through the meshing of the transmission gear 9 and the gear groove 402 to change the angle of the robot body 1. When the angle of the robot body 1 meets the standard, the power supply to the rotating motor 5 is stopped. S5: After the robotic arm body 1 moves the drying rod of the dried persimmon strips to the designated position, the telescopic cylinder 6 extends the telescopic column to make the drying rod of the dried persimmon strips lock into the designated position. At this time, the robotic arm body 1 and the drying rod of the dried persimmon strips are not in contact. S6: After the robotic arm body 1 completes the above movement, it moves out of the placement position and moves to the drying pole of the next batch of dried persimmon strips to be transported, repeating the above process.
[0026] In this embodiment, the width of the robotic arm body 1 and the number of fixed teeth 2 can be adjusted as needed.
[0027] In this embodiment, the rotary motor 5 and the telescopic cylinder 6 can be equipped with PID control programs and components to achieve automated control.
[0028] The specific implementation process of this invention is as follows: The specific operation and usage process and component collaboration logic of this invention are as follows: Robotic Arm Main Body 1: Serving as the carrier for directly gripping the drying racks, its side opening design accommodates the gaps in the drying rack array. The internal fixing teeth 2 employ a pointed structure, utilizing gravity guidance to automatically slide the drying racks into the bottom of the teeth, forming a mechanical lock to prevent slippage during handling. Its adjustable width adapts to different rack sizes.
[0029] Rotary connecting shaft 4: It adopts a double-layer structure of inner shaft 401-outer shaft 403. The inner shaft 401 meshes with the transmission gear 9 of the rotating motor 5 through the upper gear groove 402. The outer shaft 403 is fixedly connected to the robot body 1, forming a "fixed outer shaft - rotating inner shaft" separation motion mode, realizing precise angle control of the robot body 1.
[0030] Rotating motor 5: Drives the inner shaft 401 to rotate through the transmission gear 9, which can be used in conjunction with the PID control system to achieve precise angle control and meet the angle adjustment requirements when placing the drying rack.
[0031] Telescopic cylinder 6: Drives the robot body 1 to rise and fall vertically through the telescopic arm, and works in conjunction with the rotating motor 5 to form a three-dimensional spatial motion capability, realizing a complete action chain of "lifting-carrying-placing".
[0032] Connection base 7: Connects to an external moving structure (such as an AGV trolley) through four corner threaded holes 10, serving as an interface unit between the robot and the external system.
[0033] Collaborative workflow: Insertion and positioning stage (S1): The main body 1 of the robot arm is inserted into the gap of the drying rod through the opening. The tip of the fixing tooth 2 guides the drying rod to slide into the bottom of the tooth to form a mechanical lock, ensuring that the position of the drying rod is fixed before transportation.
[0034] Vertical lifting stage (S2): The telescopic cylinder 6 retracts, driving the robot arm body 1 and the drying rod to rise as a whole. The outer shaft 403 is rigidly connected to the robot arm body 1 through the connecting column 8, ensuring the stability of vertical movement.
[0035] Horizontal transport stage (S3): The external moving structure transports the robotic arm system to the target area through the connecting base 7. During this stage, the rotating motor 5 is locked to keep the angle of the robotic arm body 1 fixed.
[0036] Angle adjustment stage (S4): After reaching the target position, the rotating motor 5 drives the inner shaft 401 to rotate through the transmission gear 9, while the outer shaft 403 remains fixed, thereby achieving precise angle adjustment of the robot body 1 to meet specific placement angle requirements.
[0037] Precision placement stage (S5): The telescopic cylinder 6 extends to lower the robotic arm body 1. After the drying rod is inserted into the target position, the tip of the fixing tooth 2 automatically unlocks, and the robotic arm body 1 is completely separated from the drying rod, ensuring contactless placement.
[0038] Reset cycle phase (S6): The robot body 1 exits the placement position, returns to the starting point through the moving structure, and repeats the above process to achieve batch handling.
[0039] Collaborative control logic: The rotary motor 5 and the telescopic cylinder 6 achieve collaboration through a PID control system: During vertical movement, the telescopic cylinder 6 adjusts its height, and the rotary motor 5 pre-adjusts its angle based on the position information; the telescopic cylinder 6 adjusts its lifting speed based on the angle information, forming a closed-loop control. The adjustable characteristics of the number of fixed teeth 2 and the width of the robot body 1 enable rapid model changeover through modular design, adapting to drying rack arrays of various diameters.
