Description

Technical Field

[0001] This invention relates to the field of robotic arm technology, specifically an auxiliary robotic arm for the production and processing of packaging paper boxes. Background Technology

[0002] Packaging cardboard box production and processing is a key process in modern logistics and commodity manufacturing. Its core involves folding, shaping, gluing, or binding pre-cut and creasing cardboard (raw material) to ultimately form a three-dimensional container with a specific spatial structure. With the development of industrial automation technology, existing packaging production lines generally use program-controlled robotic arms as the core execution unit. These devices send preset instructions through a central processor, using servo motors and precision transmission mechanisms to drive multi-joint arms or linear modules, simulating the complex movement trajectory of a human hand in space. This enables automatic gripping, handling, and posture adjustment of cardboard, aiming to replace manual labor in highly repetitive packaging operations.

[0003] However, existing program-controlled robotic arms still have limitations when performing high-precision packaging auxiliary tasks. In particular, referring to the prior art document CN120840152A (a robotic arm for carton packaging production equipment), it can be seen that although such devices have basic automation functions, their control logic mainly relies on the simple cooperation between a single linear drive unit (such as an electric push rod or linear module) and a rigid end effector (such as an insert plate). By controlling the rigid insert plate to forcibly insert into the gap of the cardboard and using linear lifting motion to physically open the folded cardboard. This rigid, program-based opening method has significant drawbacks when performing delicate tasks requiring flexible contact: Firstly, the rigid inserts under program control lack the ability to sense and adaptively adjust contact torque. When opening the cardboard, excessive rigidity can easily damage the cardboard fiber structure, leading to cracks at creases or damage to the appearance, making it difficult to guarantee the quality of the finished product. Secondly, the end effector structure of this type of device is fixed, lacking the ability to flexibly program and control multi-degree-of-freedom spatial postures. It is difficult to adapt to the angle flipping or centering adjustment required when the cardboard box flows between different workstations. Furthermore, the single physical opening mechanism has poor compatibility with different specifications and sizes, and the program parameters need to be recalibrated during the adjustment process, which limits the flexible production capacity of automated production lines when facing small-batch, multi-variety packaging needs. Summary of the Invention

[0012] Furthermore, the adjustment component includes: A longitudinal adjustment component, disposed on the guide frame, is used to drive the upper clamping plate and the lower clamping plate to move relative to each other in order to adjust the longitudinal clamping distance; A lateral adjustment component, disposed on the guide frame, is used to drive the two clamping plates at the same horizontal position to move relative to each other in order to adjust the lateral distribution distance.

[0013] Furthermore, the longitudinal adjustment member includes: Guide block one: A pair of T-shaped guide blocks one are fixedly connected to the back side of the vertical section of each clamping plate. The guide blocks one are arranged horizontally relative to the long side of the guide frame. A pair of movable strips are slidably connected to the inner side of the guide frame. The movable strips are arranged parallel to the long side of the guide frame. The guide blocks are slidably connected to the inner side of the corresponding movable strips to form a guiding fit. A drive rod is rotatably connected to the inner side of the guide frame. A symmetrical threaded section is provided on the outer side of the drive rod.

[0015] Compared with existing technologies, this auxiliary robotic arm for packaging paper box production and processing has the following advantages: I. This invention integrates longitudinal and transverse adjustment components on the guide frame and utilizes the threaded engagement principle of the drive rod and the moving bar to achieve precise and independent adjustment of the longitudinal clamping thickness of the upper and lower clamping plates and the transverse distribution distance of the clamping plates on the same horizontal plane. This ensures that the robotic arm can be accurately aligned according to the specific size of the cardboard box, improving the stability of the gripping and the adaptability to irregularly shaped cardboard boxes.

[0016] Second, this invention uses a servo motor in the rotating assembly to drive a gear pair to rotate the rotating shaft and guide frame. Combined with the electric push cylinder in the telescopic component to drive the guide plate to move along the guide rod axially, this invention enables the guide frame to flexibly switch between horizontal and vertical postures and fine-tune its axial position. This gives the robot arm multi-degree-of-freedom spatial motion capabilities and meets the needs of complex processes on the packaging production line for changing the posture of the paper box.

[0017] Third, by opening positioning holes on the connecting plate and cooperating with electric push cylinder two and electric push cylinder three to drive positioning block one and positioning block two to selectively engage, the present invention achieves mechanical rigid locking of the guide frame in a horizontal or vertical state, effectively eliminating transmission gaps, ensuring the stability of the carton posture when operating at high speed and grabbing heavy objects, and avoiding positional deviations caused by vibration.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-9 As shown, the present invention provides a technical solution: an auxiliary robotic arm for the production and processing of packaging paper boxes. The device as a whole is a program-controlled end-effector, which is installed on the control end of a multi-joint automated robotic arm 2 through a standard interface. This device utilizes preset control commands and the cooperation of internal transmission mechanisms to not only simulate human hand movements to adaptively grasp individual paper boxes, but also has been specially designed for the handling needs of stacks of paper boxes. It can realize bottom scooping, stable clamping and spatial orientation of the entire stack of paper boxes. The auxiliary robotic arm mainly includes a mounting plate 1, a support plate 3, a guide frame 4, a clamping plate 5, an adjustment component 6 and a rotating component 7.

[0022] Mounting plate 1 serves as the connection base and signal input terminal for the entire device. It is detachably mounted on the end of robotic arm 2 via a quick connector. The internal structure of mounting plate 1 includes a guide cavity 8. A pair of hydraulic cylinders 9 are fixedly connected inside the guide cavity 8. These two hydraulic cylinders 9 serve as the main linear drive source, with their telescopic rods extending to both sides of the guide cavity 8. Inside the guide cavity 8, a pair of L-shaped support plates 3 are symmetrically and movably connected. The horizontal section of each support plate 3 slides within the guide cavity 8 and is fixedly connected to the end of the telescopic rod of the corresponding hydraulic cylinder 9. By controlling the extension and retraction stroke of the hydraulic cylinders 9 through a program, the two support plates 3 can be driven to make precise linear movements in opposite directions within the guide cavity 8, thereby macroscopically adjusting the opening and closing distance between the two clamping units to accommodate stacks of paper boxes of different widths.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9 As shown, a guide frame 4 is rotatably mounted on the inner side of each support plate 3. The guide frame 4 is the key carrier for installing the fixture and realizing posture changes. Its structure includes a frame-shaped guide frame 401 and a connecting plate 402 fixed in the middle of the back side of the guide frame 401. A rotating assembly 7 is provided at the bottom end of the support plate 3. This assembly works in concert under the drive of a control signal to change the spatial placement posture of the guide frame 4. The rotating assembly 7 is mainly composed of a telescopic component and a rotating component. The telescopic component includes a pair of guide rods 706 fixed on the outside of the support plate 3. A guide cylinder 707 is movably connected to the guide rods 706. A guide plate 708 is fixedly connected to the end of the guide cylinder 707. An electric push cylinder 709 is also fixed on the outside of the support plate 3. Its telescopic rod is fixedly connected to the guide plate 708 and is used to drive the guide plate 708 to move axially along the guide rods 706, thereby adjusting the position of the guide frame 4. The distance between the guide frame 4 and the support plate 3 is specified. The rotating component includes a rotating cylinder 701 rotatably connected to the bottom of the support plate 3, and a rotating shaft 702 with a polygonal cross-section fixed to the back side of the connecting plate 402. The rotating shaft 702 movably passes through the axis of the rotating cylinder 701. A gear 703 is fixed to the outside of the rotating cylinder 701. A gear 704 meshing with the gear 703 is movably connected to the inside of the support plate 3. A servo motor 705 fixed to the outside of the support plate 3 drives the gear 704 to rotate after receiving a rotation command. When it is necessary to adjust the posture of the cardboard stack, the rotating component is activated, and the rotating shaft 702 and the guide frame 4 are rotated through gear transmission to realize the switching between the horizontal and vertical postures of the cardboard stack. At the same time, the telescopic component works in conjunction to finely adjust the axial position of the guide frame 4 to avoid interference during the posture change process.

[0024] To ensure that the guide frame 4 has sufficient rigidity to resist the reaction force during grasping after the attitude is adjusted by the program control, this device is also designed with a dual positioning and locking structure. A pair of positioning holes 10 are opened on the back side of the connecting plate 402. An electric push cylinder 11 is fixed on the outer side of the bottom of the support plate 3, and the end of its telescopic rod is connected to a positioning block 12 that matches the positioning hole 10. An electric push cylinder 13 is also fixed on the outer side of the support plate 3, and the end of its telescopic rod is connected to a positioning block 14 that also matches the positioning hole 10. When the guide frame 4 rotates to the horizontal position, the electric push cylinder 11 responds to the command to push the positioning block 12 into the positioning hole 10 to achieve horizontal locking. When rotated to the vertical position, the electric push cylinder 13 responds to the command to push the positioning block 14 into the positioning hole 10 to achieve vertical locking. This mechanical locking structure ensures the stability of operation in high-speed automated cycles.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 ,Figure 5 and Figure 8 As shown, the guide frame 4 is equipped with clamping plates 5 and adjusting components 6 for precise clamping of the cardboard stack. The clamping plates 5 are L-shaped, including two upper clamping plates 5 and two lower clamping plates 5. The horizontal section of the lower clamping plate 5 is specially designed to extend into the bottom of the cardboard stack. When approaching the cardboard stack, the horizontal section of the lower clamping plate 5 fits against the bottom of the cardboard stack, thereby lifting the entire stack of cardboard boxes during the advancement of the robotic arm. The adjusting components 6 are set on the guide frame 401 and are divided into longitudinal adjusting components and transverse adjusting components. The longitudinal adjusting components include a T-shaped guide block 601 fixed to the back side of the clamping plate 5 and a moving strip 602 slidably connected to the inner side of the guide frame 401. The guide block 601 and the moving strip 602 are slidably engaged. The drive rod 603 is rotatably connected inside the guide frame 401, passes through the two moving strips 602 and is threadedly engaged with them. The servo motor 604 is adjusted according to... Input parameters drive the drive rod 603 to rotate, thereby controlling the two moving bars 602 to move closer or further apart, which in turn drives the upper clamping plate 5 and the lower clamping plate 5 to adjust the longitudinal distance. The lateral adjustment component includes a T-shaped guide block 605 fixed to the back of the clamping plate 5 and a moving bar 606 slidably connected to the inside of the guide frame 401. The guide block 605 and the moving bar 606 are slidably engaged. The drive rod 607 is rotatably connected inside the guide frame 401, passes through the two moving bars 606 and is threadedly engaged with them. The servo motor 608 drives the drive rod 607 to rotate according to the input parameters, thereby controlling the two moving bars 606 to move closer or further apart, and thus adjusting the lateral distance between the two clamping plates 5 on the same horizontal plane. This design of independent longitudinal and lateral adjustment allows the robotic arm to quickly adapt to stacks of packaging cartons of various specifications through program control.

[0026] For example, on the production line of an automated packaging and logistics center, this auxiliary robotic arm is installed at the end of a six-axis robot and is responsible for gripping flat cardboard boxes of different sizes on the conveyor line and transferring them to the packing station. During operation, the system first automatically adjusts the longitudinal and transverse spacing of the clamping plate 5 according to the detected cardboard box specifications to securely cover the cardboard box. Then, it drives the guide frame 4 to rotate 90 degrees and uses the positioning and locking mechanism to precisely flip the cardboard box from a horizontal position to a vertical position. Subsequently, the robotic arm, in coordination with the overall movement, smoothly inserts the cardboard box into the sorted packaging box. The entire process requires no manual intervention and achieves efficient adaptive gripping and spatial reversal operations for cardboard boxes of various specifications.

[0027] Working Process: First, the central control system sends instructions based on the specifications of the stack of cardboard boxes to be gripped, controlling the longitudinal and transverse adjustment components in the adjustment assembly 6 to pre-adjust the covering space of the upper and lower clamping plates 5. Then, the robotic arm moves to one side of the cardboard stack, and the hydraulic cylinder 9 responds to the instructions to adjust the overall spacing of the support plates 3, ensuring that the horizontal section of the lower clamping plate 5 is precisely aligned with the bottom gap of the cardboard stack. Next, the robotic arm advances horizontally, the horizontal section of the lower clamping plate 5 inserts into the bottom of the cardboard stack, and lifts the entire stack of cardboard boxes. During the lifting process, the servo motor 604 activates to drive the longitudinal adjustment component, causing the upper clamping plate 5 to move downwards while the lower clamping plate 5 moves upwards in coordination. The upper and lower clamping plates 5 move closer together, tightly clamping the entire cardboard stack from all sides, ensuring that the cardboard boxes will not slip during transport. After clamping confirmation, if it is necessary to change the posture of the cardboard stack... For example, at the packing station, if a stack of cardboard boxes that was originally placed horizontally needs to be inserted vertically, the system starts the servo motor 705 in the rotating component 7. With the help of the telescopic component, the guide frame 4 and the clamped stack of cardboard boxes are rotated 90 degrees upward from the horizontal position to the vertical position. The system also controls the electric push cylinder 13 to push the positioning block 14 into the positioning hole 10 for rigid locking. Then, the robotic arm delivers the vertical stack of cardboard boxes to the top of the packaging box and completes the unloading. If the stack of cardboard boxes needs to be turned in the palletizing process, the system unlocks the system and controls the servo motor 705 to drive the stack of cardboard boxes to continue rotating 90 or 180 degrees. After adjusting to the optimal stacking angle, the system locks the stack again to complete the precise palletizing. This device achieves the picking, clamping and multi-angle posture changes of stacked cardboard boxes by programming control of multiple drive components, thereby improving the automation efficiency of packaging production.

[0028] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
