Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a carton placement platform and a robotic arm carton opening device. Background Technology

[0002] Corrugated cardboard boxes are a common packaging method on the market. Before use, the cardboard box is usually folded into a flat structure. When packing or placing goods, the cardboard box needs to be unfolded into a three-dimensional structure, then the edges are sealed with tape before packing or placing the goods.

[0003] With technological advancements and the emergence of robotic carton-opening robots, carton opening can now be automated in a streamlined process. For example, CN2015201306902 discloses a "carton-opening and packing robot," which includes a robot and its control device. Carton stacking sections are located on both sides of the robot, and a product conveyor belt is positioned in front of the robot, carrying products to be packed. The robot includes a robotic arm and a fixed base. The robotic arm can rotate relative to the fixed base along a vertical axis. This robotic arm can pick up a designated carton from the carton stacking section, unfold it, and pack the carton onto the products to be packed on the conveyor belt.

[0004] However, the cardboard boxes placed in the cardboard box stacking section of this patent are not limited in position. When picking up the cardboard boxes, the cardboard boxes below will shift, which will cause the subsequent packing to be unable to be completed smoothly and often requires manual intervention.

[0009] Optionally, the adjustment component includes a length direction adjustment mechanism, which includes a pair of guide rails arranged along the length direction of the frame, and a pair of first sliders respectively arranged on the pair of guide rails. The pair of first sliders are also provided with a moving platform, and the moving platform is provided with a vertical support. The vertical support is parallel to the width direction of the frame and is used to connect the corner moving limit plate of the carton.

[0010] Optionally, the adjustment assembly further includes a width direction adjustment mechanism, which includes a pair of slide rails disposed on the side of the vertical support facing the fixed platform, and a pair of second sliders respectively disposed on the pair of slide rails. A vertical connecting plate is provided on the pair of second sliders, and the carton corner movement limiting plate is disposed on the vertical connecting plate.

[0011] The pair of slide rails are arranged vertically and parallel to the width direction of the frame.

[0012] Optionally, limiting posts are provided on the two adjacent sides of the corner where the corner fixing limiting plate of the carton is located, and the limiting posts are used to limit the two adjacent sides of the carton.

[0013] Optionally, the first slider and the second slider are respectively provided with locking mechanisms. The locking mechanisms pass through the first slider or the second slider and abut against the guide rail or slide rail to fix the first slider on the guide rail or the second slider on the slide rail.

[0014] Optionally, a warning button is also included. The warning button is located on the other corner of the frame and connected to the frame via a connecting rod. The warning button includes a stop button and a start button for controlling the operation of the fully automatic mechanical gripper.

[0015] Optionally, it also includes a support leg, which includes a column and an adjustable foot pad disposed at one end of the column, and the other end of the column is connected to the frame.

[0016] Optionally, the carton corner fixing limit plate and the carton corner moving limit plate each have a pair of mutually perpendicular limiting surfaces.

[0017] This application also provides a robotic arm box opening device, including the aforementioned carton placement platform, and further including a fully automatic robotic gripper and a fully automatic box sealing machine, wherein a plurality of the carton placement platforms and the fully automatic box sealing machine are arranged around the fully automatic robotic gripper.

[0018] Optionally, the fully automatic mechanical gripper is positioned at the center of the robotic arm box opening device, and the fully automatic box sealing machine is positioned in front of the fully automatic mechanical gripper; the robotic arm box opening device includes two pairs of carton placement platforms, one pair of which is respectively positioned on the left and right sides of the fully automatic mechanical gripper, with one end equipped with an adjustment component facing the fully automatic box sealing machine, and the other pair of which is parallel to the rear side of the fully automatic mechanical gripper, with the side equipped with a fixing platform facing the centerline direction of the fully automatic mechanical gripper.

[0019] Compared with the prior art, the technical solution provided in this application has the following advantages:

[0020] The aforementioned carton placement platform, through the construction of a rectangular frame, a fixed platform, and adjustment components, forms the main structure of the platform. This allows the carton placement platform to simultaneously perform the functions of fixing and loading cartons and adjusting their size, thereby adapting to the placement needs of cartons of different sizes. Furthermore, this embodiment incorporates a carton corner fixing limit plate and a carton corner moving limit plate on the frame, arranged diagonally. This ensures that the two opposite corners of the carton can contact and be positioned with the limit plates, effectively achieving diagonal positioning of the carton. The carton corner fixing limit plate, located at one corner of the fixed platform, provides a stable, initial positioning reference point for the carton, ensuring that at least one corner of the carton is accurately constrained during placement.

[0021] Specifically, the corner moving limit plate of the carton, through its cooperation with the adjustment component and its sliding connection with the frame, possesses the ability to slide along the two adjacent side edges of the frame, i.e., the length and width directions in the conventional sense. Operators can flexibly adjust the position of the corner moving limit plate according to the actual size of the carton to be placed, thereby precisely matching the other opposite corner of the carton. Furthermore, the corner moving limit plate can be locked at any point within its adjustment plane, ensuring that after the carton size is determined, the limit plate can be firmly fixed, preventing displacement of the carton during placement or subsequent operations. This guarantees wide adaptability to different carton sizes and the stability and accuracy of placement. This design significantly improves the platform's versatility and ease of operation.

Detailed Implementation

[0030] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0031] See Figure 1 and Figure 2 An embodiment of this utility model provides a carton placement platform 3, including a rectangular frame 3.1, a fixed platform 3.4 and an adjustment component, which are respectively disposed on the frame 3.1;

[0032] The frame 3.1 is also provided with a carton corner fixing limit plate 3.2 and a carton corner moving limit plate 3.12. The carton corner fixing limit plate 3.2 and the carton corner moving limit plate 3.12 are arranged diagonally. The carton corner fixing limit plate 3.2 is set on the corner of the frame 3.1 on the side where the fixed platform 3.4 is installed. The carton corner moving limit plate 3.12 is set on the adjustment component and is slidably connected to the frame 3.1 through the adjustment component.

[0033] The carton corner movement limit plate 3.12 has an adjustment state that slides along the direction of the two adjacent side frames of the frame 3.1, and a fixed limit state that is locked at any point within the movement range of the adjustment component.

[0034] In this embodiment, the main structure of the platform is constructed by setting a rectangular frame 3.1, a fixed platform 3.4, and adjustment components. This enables the carton placement platform 3 to simultaneously perform the functions of fixing and loading cartons and adjusting their size, thereby adapting to the placement needs of cartons of different sizes. Furthermore, this embodiment sets a carton corner fixing limit plate 3.2 and a carton corner moving limit plate 3.12 on the frame 3.1, arranging them diagonally. This allows the two opposite corners of the carton to contact and be positioned with the limit plates respectively, effectively achieving diagonal positioning of the carton. The carton corner fixing limit plate 3.2 is located at one corner of the fixed platform 3.4, providing a stable, initial positioning reference point for the carton, ensuring that at least one corner of the carton is accurately constrained during placement.

[0035] Specifically, the corner moving limit plate 3.12, through its cooperation with the adjustment component and its sliding connection with the frame 3.1, possesses the ability to slide along the two adjacent sidewalls of the frame 3.1, i.e., the conventional length and width directions. Operators can flexibly adjust the position of the corner moving limit plate 3.12 according to the actual dimensions of the carton to be placed, thereby precisely matching the other opposite corner of the carton. Furthermore, the corner moving limit plate 3.12 can be locked at any point within its adjustment plane, ensuring that the limit plate is firmly fixed after the carton size is determined, preventing displacement of the carton during placement or subsequent operations, thus guaranteeing wide adaptability to different carton sizes and the stability and accuracy of placement. This design significantly improves the platform's versatility and ease of operation.

[0036] See Figures 1 to 4 In one embodiment, the adjustment component includes a length direction adjustment mechanism, which includes a pair of guide rails 3.5 arranged along the length direction of the frame 3.1, and a pair of first sliders 3.6 respectively arranged on the pair of guide rails 3.5. The pair of first sliders 3.6 are also provided with a moving platform 3.7, and the moving platform 3.7 is provided with a vertical support 3.8. The vertical support 3.8 is parallel to the width direction of the frame 3.1 and is used to connect the carton corner moving limit plate 3.12.

[0037] In this embodiment, the adjustment assembly significantly enhances the accuracy and stability of the adjustment of the carton corner movement limit plate 3.12 along the length of the frame 3.1. Specifically, a pair of guide rails 3.5 arranged along the length of the frame 3.1 provide a clear guiding path for the entire adjustment action, ensuring the linearity and directional accuracy of the movement. The pair of first sliders 3.6 arranged on the guide rails 3.5 ensure smooth and stable movement, reducing the possibility of friction and jamming. Furthermore, because the two sliders share the load, the support stability and anti-eccentric load capacity of the moving platform 3.7 and its upper components are improved.

[0038] The moving platform 3.7, acting as an intermediary connecting the slider and subsequent structures such as the vertical bracket 3.8, precisely transmits the linear motion from the guide rail 3.5 and the slider, and provides a stable mounting base. The vertical bracket 3.8, mounted on this moving platform 3.7, is oriented parallel to the width direction of the frame 3.1. When the length adjustment mechanism is activated, i.e., when the first slider 3.6 moves along the guide rail 3.5, the entire vertical bracket 3.8, along with the fixed carton corner movement limit plate 3.12, moves as a whole along the length direction of the frame 3.1.

[0039] This embodiment achieves linear adjustment of the carton corner movement limiting plate 3.12 along the length dimension of the carton placement platform 3. Simultaneously, the design of the vertical support 3.8 parallel to the width direction of the frame 3.1 provides an orthogonal reference, already precisely positioned in the length direction, for the adjustment of the carton corner movement limiting plate 3.12 in the width direction. This facilitates precise positioning of the entire adjustment assembly for the carton corner in both the length and width directions within a two-dimensional plane.

[0040] See Figures 1 to 4 In one embodiment, the adjustment assembly further includes a width direction adjustment mechanism, which includes a pair of slide rails 3.9 disposed on the side of the vertical support 3.8 facing the fixed platform 3.4, and a pair of second sliders 3.10 respectively disposed on the pair of slide rails 3.9. A vertical connecting plate 3.11 is provided on the pair of second sliders 3.10, and a carton corner movement limiting plate 3.12 is disposed on the vertical connecting plate 3.11. The pair of slide rails 3.9 are arranged vertically and are parallel to the width direction of the frame 3.1.

[0041] In this embodiment, by providing a pair of vertically aligned slide rails 3.9 on the side of the vertical support 3.8 facing the fixed platform 3.4, which are parallel to the width direction of the frame 3.1, and by providing a pair of second sliders 3.10 on these slide rails 3.9 and a vertical connecting plate 3.11 that ultimately supports the carton corner movement limiting plate 3.12, the precise and stable movement and positioning of the carton corner movement limiting plate 3.12 in the width direction of the frame 3.1 is achieved.

[0042] First, the parallel orientation of the slide rail 3.9 to the width direction of the frame 3.1 clarifies the adjustment freedom of this mechanism, namely, the adjustment in the width direction. The slide rail 3.9 is vertically positioned, either above or below another, providing structural stability and guiding accuracy for the second slider 3.10 and the vertical connecting plate 3.11 that slide on it. This effectively resists the overturning moment that may occur during width adjustment or carton positioning, ensuring smooth movement and accurate positioning of the vertical connecting plate 3.11 in the width direction.

[0043] Secondly, since the corner moving limit plate 3.12 of the carton is directly set on the vertical connecting plate 3.11, the position of the corner moving limit plate 3.12 of the carton in the width direction of the frame 3.1 can be directly and accurately adjusted by controlling the position of the second slider 3.10.

[0044] In summary, the width adjustment mechanism works in conjunction with the aforementioned length adjustment mechanism to form an orthogonal, two-dimensional adjustment system. The operator can first use the length adjustment mechanism to set the position of the carton corner movement limit plate 3.12 in the length direction, and then use this width adjustment mechanism to precisely set its position in the width direction (or vice versa). The adjustments in the two directions are independent and do not interfere with each other. This allows the entire carton placement platform 3 to adapt extremely flexibly to cartons of various lengths and widths, ensuring precise positioning and subsequent secure limiting of the carton corners, thereby greatly improving the platform's versatility, operational accuracy, and ease of adjustment.

[0045] See Figures 1 to 4 In one embodiment, limiting posts 3.3 are provided on the two adjacent sides of the corner where the corner fixing limiting plate 3.2 of the carton is located. The limiting posts 3.3 are used to limit the two adjacent sides of the carton.

[0046] In this embodiment, by setting limiting posts 3.3 on the two adjacent sides of the corner where the corner fixing limiting plate 3.2 is located, the three-dimensional stability of the carton during placement is effectively improved. The limiting posts 3.3 are respectively set on the two adjacent sides of the corner, and together with the corner fixing limiting plate 3.2, they form a clamping and limiting structure for the two adjacent sides of one side of the carton. This arrangement can not only position one corner of the carton, but also simultaneously constrain the two sides corresponding to the corner, further preventing the carton from undergoing horizontal displacement or rotational shift during placement.

[0047] This structure simplifies the precise calibration process for carton position. Users only need to push the carton into the limiting area formed by the limiting post 3.3 and the limiting plate to quickly and accurately control the carton's position. Compared to a single-point limiting structure, this double-sided limiting method has significant advantages in positioning accuracy and anti-interference capability, making it particularly suitable for automated or semi-automated operation scenarios requiring rapid, batch placement of cartons.

[0048] See Figure 3 In one embodiment, the first slider 3.6 and the second slider 3.10 are respectively provided with locking mechanisms 3.14. The locking mechanisms 3.14 pass through the first slider 3.6 or the second slider 3.10 and abut against the guide rail 3.5 or the slide rail 3.9 to fix the first slider 3.6 on the guide rail 3.5 or fix the second slider 3.10 on the slide rail 3.9.

[0049] In this embodiment, by providing locking mechanisms 3.14 on the first slider 3.6 and the second slider 3.10 respectively, the stability and safety of the adjustment assembly are effectively improved. Specifically, the locking mechanism 3.14 passes through the first slider 3.6 or the second slider 3.10 and can abut against its corresponding guide rail 3.5 or slide rail 3.9, thereby reliably locking the slider in a predetermined position after adjustment.

[0050] The introduction of this structural design allows users to quickly fix the slider using the locking mechanism 3.14 after adjusting the position of the carton limit plate (whether in the length or width direction), preventing accidental movement of the slider under equipment operation, vibration, or external force. Especially in scenarios with frequent adjustments or continuous operation, the locking mechanism 3.14 provides the necessary structural rigidity to ensure the long-term stability of the limit plate position and the accuracy of the limit.

[0051] Furthermore, the locking mechanism 3.14 has a relatively simple structure and can adopt common forms such as rotating screws, eccentric wheels, or elastic pins, which facilitates manufacturing and maintenance without increasing the complexity of the system, while improving the convenience and reliability of operation. The first slider 3.6 and the second slider 3.10 correspond to the adjustment mechanisms in the length and width directions, respectively. Therefore, the locking mechanism 3.14 is also designed to act on the sliding units in these two directions, ensuring the accurate positioning and secure fixation of the entire moving limit system after multi-directional adjustment.

[0052] In summary, this embodiment, by equipping the slider with a locking mechanism 3.14, achieves rapid locking and long-term stability of the position adjustment of the limit plate, further improving the operational reliability, positioning accuracy, and adaptability of the carton placement platform 3 to various carton specifications.

[0053] See Figure 1 , Figure 2 and Figure 4 In one embodiment, a warning button 3.13 is also included. The warning button 3.13 is located on the other corner of the frame 3.1 and connected to the frame 3.1 via a connecting rod. The warning button 3.13 includes a stop button and a start button, used to control the operation of the fully automatic mechanical gripper 1. In this embodiment, the warning button 3.13 component includes a stop button and a start button, respectively used to control the start and stop operation of the mechanical gripper. After the carton is placed in place, the user can instruct the gripper to perform the gripping operation via the start button. In case of an abnormality or when the operation needs to be interrupted, the user can quickly cut off the mechanical gripper's action command via the stop button, thereby achieving an emergency stop. This design greatly enhances the safety and initiative of the operation process, and is especially suitable for scenarios such as automated production lines or packaging lines.

[0054] Furthermore, the warning button 3.13 is positioned at the other corner of frame 3.1 and fixed by a connecting rod. This arrangement allows for quick access by personnel during operation without interfering with the normal use of the carton placement area. This layout considers ergonomic principles, optimizing the accessibility and visibility of the button, and improving overall operational convenience and responsiveness. Each carton placement platform 3 is equipped with a warning button 3.13, which controls the operation of the fully automatic mechanical gripper 1 on each platform 3. This ensures that adding a carton to one platform 3 does not affect the gripping operations of other tasks.

[0055] See Figure 1 , Figure 2 and Figure 4 In one embodiment, the system also includes support legs, each comprising a column and an adjustable foot pad at one end of the column, with the other end of the column connected to the frame 3.1. In this embodiment, the support leg structure on the carton placement platform 3 further enhances the load-bearing capacity and installation adaptability of the entire device. The support legs include a column and an adjustable foot pad at one end of the column, with the other end of the column connected to the frame 3.1, forming a lower support for the main structure of the platform. This design gives the platform good mechanical stability, effectively bearing the dynamic loads of different sized cartons during operation, and preventing the platform from swaying or tilting.

[0056] In particular, the adjustable feet allow for fine-tuning of the support height within a certain range, enabling precise correction of the platform's overall level. This structure is especially suitable for use in uneven ground environments, quickly eliminating structural tilting caused by ground undulations by adjusting the height of each support foot, ensuring that cartons remain stable on the platform at all times. This not only helps improve limiting accuracy and operational safety but also enhances the positioning accuracy of subsequent automated gripping equipment.

[0057] See Figures 1 to 4In one embodiment, the carton corner fixing limiting plate 3.2 and the carton corner moving limiting plate 3.12 each have a pair of mutually perpendicular limiting surfaces. Specifically, in this embodiment, the cross-section of the carton corner fixing limiting plate 3.2 and the carton corner moving limiting plate 3.12 is "┌" shaped, that is, forming a corner structure with an inward opening and two vertical sides, so that it can simultaneously limit the carton corner from two orthogonal directions.

[0058] Compared to single-plane limiting, this structural design provides stronger anti-slip and anti-rotation capabilities. During the placement of the carton, once a sharp corner enters the "┌" shaped limiting structure, its two adjacent sides will be constrained by the two vertical limiting surfaces of the structure, thereby achieving precise clamping and stable positioning of the carton corner and significantly reducing the risk of displacement or deflection of the carton due to inertia, vibration, or external forces.

[0059] Furthermore, both the fixed and movable limiting plates adopt this "┌" shaped design, which helps to symmetrically limit the two sharp corners of the carton at diagonal positions, thus forming a reliable double-corner support structure and further improving the overall placement stability of the carton. Combined with the adjustable structure, the movable limiting plate can also adapt to cartons of different sizes, always maintaining an effective limiting effect.

[0060] See Figure 5 and Figure 6 An embodiment of this utility model also provides a robotic arm box opening device, including the aforementioned carton placement platform 3, as well as a fully automatic robotic gripper 1 and a fully automatic box sealing machine 2, with several carton placement platforms 3 and fully automatic box sealing machines 2 arranged around the fully automatic robotic gripper 1.

[0061] See Figure 5 and Figure 6 In one embodiment, the fully automatic mechanical gripper 1 is positioned at the center of the robotic arm box opening device, and the fully automatic box sealing machine 2 is positioned in front of the fully automatic mechanical gripper 1. The robotic arm box opening device includes two pairs of carton placement platforms 3. One pair of carton placement platforms 3 is respectively positioned on the left and right sides of the fully automatic mechanical gripper 1, with one end equipped with an adjustment component facing the fully automatic box sealing machine 2. The other pair of carton placement platforms 3 is positioned parallel to the rear side of the fully automatic mechanical gripper 1, with the side equipped with a fixing platform 3.4 facing the centerline direction of the fully automatic mechanical gripper 1.

[0062] In this embodiment, a highly efficient automated carton processing system is constructed by integrating a carton placement platform 3, a fully automatic mechanical gripper 1, and a fully automatic carton sealing machine 2. Its core technological advantage lies in achieving continuous operation from carton positioning and automatic opening and forming by the robotic arm to final automatic sealing. During this process, the carton is positioned to prevent displacement, significantly improving production efficiency and packaging quality consistency while greatly reducing reliance on manual labor.

[0063] The fully automatic robotic gripper 1 is positioned in the center, surrounded by carton placement platforms 3 and a carton sealing machine. This design optimizes the robotic arm's working path, ensuring efficient coverage of all workstations. The configuration of up to four carton placement platforms 3 not only achieves material buffering and near-continuous work cycles, supporting parallel processing and thus greatly improving overall production throughput, but also provides flexibility in handling cartons of different sizes due to its adjustability.

[0064] The specific operation process of the robotic arm unpacking device provided by this utility model is as follows: The fully automatic robotic arm rotates to the designated carton placement platform 3 according to system requirements, picks up a carton of the specified size, unfolds the carton, rotates it above the fully automatic carton sealing machine 2, performs a second fold on the bottom surface, and places the carton on the fully automatic carton sealing machine 2. The fully automatic carton sealing machine 2 seals the bottom surface of the carton with tape. Then, the fully automatic robotic arm moves away from the fully automatic carton sealing machine 2, and the carton is conveyed out by the conveyor belt on the fully automatic carton sealing machine 2.

[0065] When a carton placement platform 3 needs to be added, the operator presses the stop button in the warning button 3.13 of that platform. The fully automatic mechanical gripper 1 pauses its carton-grabbing operation on that platform, without affecting the operation of other carton placement platforms 3. The locking mechanism 3.14 is then opened, and the length and width adjustment mechanisms are moved outwards to a position where a carton can be placed. The carton is then placed, with one corner aligned with the corner limiting plate. Once full, the length and width adjustment mechanisms are moved so that the corner limiting plate 3.12 locks the other opposite corner of the carton. The locking mechanism 3.14 is then locked, and the start button in the warning button 3.13 is pressed to begin the carton-grabbing operation.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
