Description

Technical Field

[0001] This utility model relates to the field of material packaging technology, and in particular to a box-packing guide device and box-packing system. Background Technology

[0002] In the material packing process of existing automated production lines, robots typically pick up materials and move them to designated positions within the cartons to complete the packing. However, in existing automated packing systems, cartons may not be fully unfolded or may exhibit partial deformation during transport or storage. When placing materials, robots are prone to jamming, tipping over, or failing to accurately place them in the target position due to abnormal carton shapes, directly affecting the continuity of packing. Furthermore, in high-cycle production modes, to meet capacity demands, robots place materials at high speeds, and incompletely unfolded cartons can easily cause hard impacts between the materials and the cartons, leading to quality problems such as surface damage and structural damage. To address this deficiency, existing technologies typically deploy operators at key workstations to correct carton shapes or push cartons back into place. However, this method is highly dependent on manual labor, inefficient, and poses certain safety hazards.

[0003] Therefore, existing automated packing systems need to be improved to overcome the shortcomings of the existing technology. Utility Model Content

[0004] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a packing guide device. This packing guide device uses a guide flap to guide materials into the carton and correct the placement of the materials, reducing the mutual impact between the materials and the carton, avoiding damage to the materials and the carton, and improving the packing efficiency of the materials.

[0005] A packing guide device includes a frame with a packing position on the frame and a plurality of guide components arranged above the packing position, each group of guide components being arranged around the packing position;

[0006] Each of the guiding components includes a guide flap and a reset structure. The guide flap is rotatably mounted on the frame, so that when the guide flap is squeezed by the material, it rotates and opens the carton flap. The reset structure is located between the frame and the guide flap, and pushes the guide flap to reset when the guide flap is not squeezed.

[0007] In one embodiment, the reset structure can be a spring. In practical applications, the packing guide device works as follows: the carton is conveyed to the packing position via the conveyor line; after the infrared sensor detects that the carton has arrived at the correct position, it sends a signal, and the production line control system stops conveying.

[0008] The robotic arm grabs air conditioning materials (such as indoor units) and moves them directly above the packing position, then descends vertically.

[0009] The bottom of the material contacts the short side of the guide flap. As the material continues to descend, the guide flap is squeezed and rotates around the hinge, while its long side simultaneously opens the corresponding flap of the carton outward.

[0010] After the materials are completely inside the carton, the robotic arm releases and retracts, and the guide flap resets under the tension of the tension spring, ready for the next packing.

[0011] After the boxes are packed, the conveyor line starts to move the cartons to the next process.

[0012] This device uses the mechanical guidance of the guide flap to make flexible contact between the material and the flap when the material enters the carton, avoiding scratches on the material surface or tearing of the carton caused by hard impact, thus reducing the product defect rate.

[0013] The guide flap provides circumferential control over the material as it descends, correcting any deviations in the material's position caused by the robotic arm's gripping action. This ensures the material is accurately placed in the pre-set position on the carton, preventing stacking interference caused by misaligned placement.

[0014] In a preferred embodiment of this utility model, the frame includes uprights and mounting pipes, and several uprights are provided, with each upright surrounding the packing position;

[0015] The mounting tube is disposed between two adjacent uprights, and both ends of the mounting tube are rotatably connected to the uprights; the guide cover is fixed on the mounting tube.

[0016] In this embodiment, the guide flap can be fixed to the middle position of the mounting tube by welding, maintaining a perpendicular angle between them. The length direction of the guide flap is consistent with the axial direction of the mounting tube. When the mounting tube rotates, the guide flap rotates synchronously with it, realizing the opening action of the carton flap. The reset structure can be a torsion spring, which is sleeved at the connection between the mounting tube and the bearing seat. One end of the torsion spring is engaged in a groove on the outer wall of the mounting tube, and the other end is fixed to the limiting block of the upright. When the guide flap is squeezed by the material and drives the mounting tube to rotate, the torsion spring generates elastic deformation and stores potential energy. After the material passes through, the torsion spring releases the potential energy and drives the mounting tube to rotate in the opposite direction, so that the guide flap automatically resets to the initial position.

[0017] The frame structure, formed by multiple uprights surrounding the loading area and connected by crossbeams, enhances overall rigidity and can withstand the compression and impact of heavier materials, solving the problem of easy deformation in traditional single-support structures. The mounting tube is rotatably connected to the uprights via bearing seats, and the return mechanism using torsion springs ensures smoother and more stable rotation of the guide flaps, avoiding the jamming that can occur with traditional hinge connections and improving responsiveness. Furthermore, the modular upright and mounting tube structure facilitates the individual replacement of damaged parts without requiring complete frame disassembly.

[0018] In a preferred embodiment of this invention, the reset structure includes an elastic element, one end of which is fixedly connected to the mounting tube, and the other end of which is fixedly connected to the upright frame; the elastic element applies a force to the mounting tube, causing the mounting tube to reset when the guide cover is not compressed.

[0019] In a preferred embodiment of this invention, a slidable rotary joint is provided on the support frame, and the end of the mounting tube is fixedly connected to the rotary joint.

[0020] Specifically, the rotary joint may include a sliding seat, a bearing assembly, and a locking mechanism. The sliding seat is made of aluminum alloy and may have a U-shaped groove structure, with its inner side fitting against the outer wall of the frame, allowing it to slide smoothly along the height of the frame.

[0021] The bearing assembly is embedded on the outside of the sliding seat, and its inner ring is interference-fitted with the end of the mounting tube; the locking mechanism includes a locking bolt and a wing nut that penetrate the side wall of the sliding seat. By inserting the locking bolt into the positioning hole at the corresponding height of the upright and tightening the wing nut, the rotary joint is fixed on the upright.

[0022] The rotary joint can slide along the height of the upright, allowing the height of the mounting pipe to be continuously adjusted within the height range of the upright. This enables quick adaptation to air conditioner cartons of different heights, solving the problem of poor adaptability of traditional fixed-height structures. The clearance fit design between the sliding seat and the upright ensures both adjustment flexibility and structural stability during operation through the rigid connection between the positioning hole and the locking bolt.

[0023] In a preferred embodiment of this invention, a limiting structure is further included to limit the reset angle of the guide cover. The limiting structure includes a limiting block disposed on the mounting tube, and the limiting block is provided with an abutting surface that abuts against the upright.

[0024] When the contact surface of the limiting block on the mounting tube comes into contact with the upright, the mounting tube is restricted in position and cannot rotate.

[0025] During operation: When the material squeezes the guide flap, the installation tube drives the limit block to rotate synchronously, so that the contact surface of the limit block separates from the upright. At this time, the guide flap can rotate freely to the maximum angle.

[0026] After the material passes through, the installation tube rotates in the opposite direction under the action of the reset structure (torsion spring) and drives the limit block back to its original position;

[0027] When the contact surface of the limit block comes into contact with the outer wall of the upright, the mounting tube is restricted from continuing to rotate, and at this time the guide cover is just reset to the initial working position.

[0028] The limiting structure can effectively limit the maximum reset angle of the guide flap, avoiding excessive swinging of the guide flap due to excessive spring force, which could cause interference with the carton or conveyor line, thus reducing safety hazards in equipment operation.

[0029] In a preferred embodiment of this invention, a snap-fit ​​seat is provided on the mounting tube, and the guide cover snaps onto the snap-fit ​​seat.

[0030] In this embodiment, the snap-fit ​​structure effectively shortens the replacement time of the guide flap, saving replacement time compared to traditional welding or bolt connection methods, and significantly reducing downtime caused by guide flap wear or specification adjustments. By replacing guide flaps of different lengths and angles, and adjusting the positioning scale of the snap-fit ​​base, it can adapt to the packing needs of more irregularly shaped cartons or special materials, solving the problem of poor versatility of traditional fixed connection structures.

[0031] In a preferred embodiment of this utility model, the guide cover includes a first plate and a second plate. The first plate is snapped onto the snap-fit ​​seat, and the second plate is disposed on one side of the first plate and facing the packing position. The second plate and the first plate are disposed at an angle A.

[0032] The angled design between the first and second plates allows the guide flap to better fit the natural opening angle of the carton flap. Combined with the guiding effect of the second plate, it can reduce the impact force when materials come into contact, avoiding the material bouncing or jamming that may occur with traditional straight structures.

[0033] In a preferred embodiment of this invention, a box-pushing structure is further included, comprising a driving device, a guide structure, and a box-pushing plate; the box-pushing plate is disposed at the box-packing position, the guide structure is disposed below the box-packing position, and the box-pushing plate is slidably disposed on the guide structure; the driving device is fixed on the frame, and the output end of the driving device drives the box-pushing plate to move on the guide structure.

[0034] In a preferred embodiment of this utility model, the guide structure includes a guide rail and a mounting base, wherein a pulley is provided on the mounting base and the pulley slides in cooperation with the guide rail;

[0035] The output end of the drive device is fixedly connected to the mounting base, and the push box plate is disposed on the mounting base.

[0036] In this embodiment, the guiding device operates as follows: after the material is packed, the control system receives a packing position signal; the drive device (cylinder) is ventilated, and the piston rod extends to push the mounting base to slide along the guide rail; the pusher plate moves synchronously with the mounting base, and after contacting the carton, pushes it from the packing position to the downstream conveyor line; after being pushed into position, the cylinder piston rod retracts, driving the pusher plate to reset to the initial position, waiting for the next pusher command.

[0037] The box-pushing structure and guiding device work together to automate the entire process from material loading to box transfer, completely replacing manual box-pushing operations and reducing labor costs.

[0038] The second objective of this utility model is to provide a packing system, including a robotic arm and a packing guide device as described above.

[0039] The beneficial effects of this utility model are as follows:

[0040] This utility model provides a carton guiding device, which includes a frame with a carton loading position on the frame. Several sets of guiding components are arranged above the carton loading position, each set surrounding the loading position. Each guiding component includes a guide flap and a reset structure. The guide flap is rotatably mounted on the frame, allowing it to rotate and open the carton flap when compressed by material. The reset structure is located between the frame and the guide flap, pushing the guide flap back to its original position when not compressed. During use, the carton guiding device uses a robotic arm to grab material and move it directly above the loading position, then lowers it vertically. The bottom of the material contacts the guide flap, and as the material continues to descend, the guide flap is compressed and rotates, opening the corresponding flap of the carton downwards. After the material has completely entered the carton, the robotic arm releases and withdraws, and the guide flap resets under the action of the reset structure, ready for the next carton loading. This guiding device uses the mechanical guidance of the guide flap to create flexible contact between the material and the carton flap as the material enters the carton, avoiding scratches on the material surface or tearing of the carton caused by hard impacts, thus reducing the product defect rate. The guide flap also provides circumferential restraint during the material's descent, correcting for material positional deviations caused by robotic arm gripping errors, ensuring accurate placement of the material in the preset position on the carton, and preventing stacking interference problems caused by misalignment.

[0041] This application also provides a packing system including the above-mentioned packing guide device, which replaces manual pushing and holding of boxes with mechanical structure, avoids close contact between operators and robotic arms and conveyor lines, reduces the risk of work-related injuries, and can correct the material position deviation caused by the robotic arm's gripping deviation during packing, ensuring that the material is accurately placed in the preset position of the carton, and avoiding the situation where the material and carton are damaged due to contact with the carton.

[0050] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0051] In the material packing process of existing automated production lines, robots typically pick up materials and move them to designated positions within the cartons to complete the packing. However, in existing automated packing systems, cartons may not be fully unfolded or may exhibit partial deformation during transport or storage. When placing materials, robots are prone to jamming, tipping over, or failing to accurately place them in the target position due to abnormal carton shapes, directly affecting the continuity of packing. Furthermore, in high-cycle production modes, to meet capacity demands, robots place materials at high speeds, and incompletely unfolded cartons can easily cause hard impacts between the materials and the cartons, leading to quality problems such as surface damage and structural damage. To address this deficiency, existing technologies typically deploy operators at key workstations to correct carton shapes or push cartons back into place. However, this method is highly dependent on manual labor, inefficient, and poses certain safety hazards.

[0052] Based on this, this application provides a packing guide device.

[0053] Example 1

[0054] like Figures 1-6 As shown, this embodiment provides a packing guide device, including a frame 1, on which a packing position is provided, and above the packing position are a plurality of guide components, each of the guide components being arranged around the packing position;

[0055] Each of the guiding components includes a guide flap 2 and a reset structure. The guide flap 2 is rotatably mounted on the frame 1, so that when the guide flap 2 is squeezed by the material, it rotates and opens the carton flap. The reset structure is located between the frame 1 and the guide flap 2, and pushes the guide flap 2 to reset when the guide flap 2 is not squeezed.

[0056] In one embodiment, the reset structure can be a spring. In practical applications, the packing guide device works as follows: the carton is conveyed to the packing position via the conveyor line; after the infrared sensor detects that the carton has arrived at the correct position, it sends a signal, and the production line control system stops conveying.

[0057] The robotic arm grabs air conditioning materials (such as indoor units) and moves them directly above the packing position, then descends vertically.

[0058] The bottom of the material contacts the short side of the guide flap 2. As the material continues to descend, the guide flap 2 is squeezed and rotates around the hinge, and its long side simultaneously opens the corresponding flap of the carton outward.

[0059] After the material has completely entered the carton, the robotic arm releases and retracts, and the guide flap 2 resets under the tension of the tension spring, waiting for the next packing.

[0060] After the boxes are packed, the conveyor line starts to move the cartons to the next process.

[0061] The device uses the mechanical guidance of the guide flap 2 to make flexible contact between the material and the flap when the material enters the carton, avoiding scratches on the material surface or tearing of the carton caused by hard impact, thus reducing the product defect rate.

[0062] The guide flap 2 provides circumferential control over the material during its descent, which can correct the material position deviation caused by the robotic arm's grasping error, ensure that the material is accurately placed in the preset position of the carton, and avoid stacking interference problems caused by misaligned placement.

[0063] Example 2

[0064] This embodiment is an improvement on the optical aspects of Embodiment 1.

[0065] like Figures 1-6 As shown, in this embodiment, the frame 1 includes a support frame 11 and a mounting pipe 12. Several supports 11 are provided, and each support 11 is arranged around the packing position.

[0066] The mounting tube 12 is disposed between two adjacent uprights 11, and both ends of the mounting tube 12 are rotatably connected to the uprights 11; the guide cover 2 is fixed on the mounting tube 12.

[0067] In this embodiment, specifically, both the upright frame 11 and the mounting tube 12 are made of lean tubing. The guide flap 2 can be fixed to the middle position of the mounting tube 12 by welding, maintaining a perpendicular angle between them; the length direction of the guide flap 2 is consistent with the axial direction of the mounting tube 12. When the mounting tube 12 rotates, the guide flap 2 rotates synchronously with it, realizing the opening action of the carton flap. The reset structure can be a torsion spring, which is sleeved at the connection between the mounting tube 12 and the bearing seat. One end of the torsion spring is engaged in a groove on the outer wall of the mounting tube 12, and the other end is fixed to the limiting block of the upright frame 11. When the guide flap 2 is squeezed by the material and drives the mounting tube 12 to rotate, the torsion spring generates elastic deformation and stores potential energy; after the material passes through, the torsion spring releases the potential energy to drive the mounting tube 12 to rotate in the opposite direction, so that the guide flap 2 automatically resets to the initial position.

[0068] The frame structure, consisting of multiple uprights 11 surrounding the loading area, is enhanced by crossbeams, increasing overall rigidity and enabling it to withstand the pressure and impact of heavier materials. This solves the problem of deformation inherent in traditional single-support structures. The mounting tube 12 is rotatably connected to the uprights 11 via bearing seats, and the torsion spring's reset mechanism ensures smoother and more stable rotation of the guide cover 2, avoiding the jamming that can occur with traditional hinge connections and improving responsiveness. Furthermore, the modular structure of the uprights 11 and mounting tube 12 facilitates the individual replacement of damaged components without requiring the complete disassembly of the frame 1.

[0069] In this embodiment, the guiding device further includes a limiting structure that limits the reset angle of the guide cover 2. The limiting structure includes a limiting block disposed on the mounting tube 12, and the limiting block is provided with an abutting surface that abuts against the upright frame 11.

[0070] When the contact surface of the limiting block on the mounting tube 12 abuts against the upright 11, the mounting tube 12 is positioned and cannot rotate. In another embodiment, the limiting block can also be mounted on the upright 11, thereby limiting the position of the mounting tube 12.

[0071] During operation: When the material squeezes the guide cover 2, the mounting tube 12 drives the limit block to rotate synchronously, so that the contact surface of the limit block separates from the upright frame 11. At this time, the guide cover 2 can rotate freely to the maximum angle.

[0072] After the material passes through, under the action of the reset structure (torsion spring), the mounting tube 12 rotates in the opposite direction and drives the limit block back to its original position;

[0073] When the contact surface of the limiting block comes into contact with the outer wall of the upright 11, the mounting tube 12 is restricted from continuing to rotate, and at this time the guide cover 2 is just reset to the initial working position. Furthermore, a 2mm thick rubber buffer pad is attached to the contact surface of the limiting block. This buffer pad is made of nitrile rubber with a Shore hardness of 60°, which can play a buffering and shock-absorbing role when the limiting block comes into contact with the upright 11, reducing collision noise and reducing structural wear.

[0074] The limiting structure can effectively limit the maximum reset angle of the guide cover 2, avoid excessive swinging of the guide cover 2 due to excessive spring force, and prevent interference with the carton or conveyor line, thus reducing the safety hazards of equipment operation.

[0075] Example 3

[0076] This embodiment is an improvement on the optical aspects of Embodiment 1.

[0077] like Figures 1-6 As shown, in this embodiment, the reset structure includes an elastic element 5. One end of the elastic element 5 is fixedly connected to the mounting tube 12, and the other end is fixedly connected to the upright frame 11. The elastic element 5 applies a force to the mounting tube 12, so that the mounting tube 12 is reset when the guide cover 2 is not squeezed.

[0078] In this embodiment, the upright frame 11 is provided with a slidable rotary joint 3, and the end of the mounting tube 12 is fixedly connected to the rotary joint 3.

[0079] Specifically, the rotary joint 3 may include a sliding seat, a bearing assembly, and a locking mechanism. The sliding seat is made of aluminum alloy and may have a U-shaped groove structure. Its inner side is clearance-fitted with the outer wall of the upright 11, allowing it to slide smoothly along the height direction of the upright 11.

[0080] The bearing assembly is embedded and installed on the outer side of the sliding seat, and its inner ring is in interference fit with the end of the mounting pipe 12; the locking mechanism comprises a locking bolt penetrating through the side wall of the sliding seat and a wing nut. By inserting the locking bolt into the positioning hole at the corresponding height of the vertical frame 11 and tightening the wing nut, the rotary joint 3 is fixed on the vertical frame 11.

[0081] In addition, the two ends of the mounting pipe 12 are respectively fixedly connected with the rotary joints 3 on the corresponding vertical frames 11. Specifically, a rigid connection with the inner ring of the bearing assembly can be formed by welding, so that the mounting pipe 12 can synchronously lift along with the rotary joint 3 and freely rotate around its own axis

[0082] The rotary joint 3 can slide along the height direction of the vertical frame 11, so that the height of the mounting pipe 12 can be continuously adjusted within the height range of the vertical frame 11, which can quickly adapt to air-conditioning cartons of different height specifications and solves the problem of poor adaptability of the traditional fixed-height structure. The clearance fit design between the sliding seat and the vertical frame 11 not only ensures the adjustment flexibility, but also ensures the structural stability in the working state through the rigid connection between the positioning hole and the locking bolt.

[0083] In this embodiment, the height adjustment operation procedure of the mounting pipe 12 is as follows:

[0084] Loosen the wing nut on the rotary joint 3 to disengage the locking bolt from the positioning hole of the vertical frame 11;

[0085] Push the mounting pipe 12 along the height direction of the vertical frame 11 to the target position (according to the height requirement of the carton);

[0086] Insert the locking bolt into the positioning hole at the corresponding height and tighten the wing nut to complete the fixation;

[0087] Repeat the above steps to adjust the rotary joints 3 on other vertical frames 11 to ensure that the mounting pipe 12 remains horizontal.

[0088] Example 4

[0089] This embodiment is improved on the basis of Embodiment 2.

[0090] As Figures 1-6 shown, in this embodiment, a clamping seat 121 is provided on the mounting pipe 12, and the guide rocking cover 2 is clamped on the clamping seat 121.

[0091] Specifically, the clamping seat 121 is formed by bending a steel plate with a thickness of 5mm, and has an overall "匚"-shaped structure, the opening width of which is adapted to the thickness of the guide rocking cover 2. Symmetrical threaded holes are provided on both side walls of the clamping seat 121, with M6 fastening bolts built in, and rubber pressing blocks are installed at the ends of the bolts.

[0092] The guide cover 2 has an insertion part at its end that matches the snap-fit ​​seat 121, and positioning grooves are provided on the corresponding positions of the two side walls of the insertion part. When the guide cover 2 is installed, its insertion part is inserted into the opening of the snap-fit ​​seat 121, the positioning groove is aligned with the threaded hole of the snap-fit ​​seat 121, and the fastening bolt is tightened to make the rubber pressure block embedded in the positioning groove, forming a rigid fixation.

[0093] In this embodiment, the snap-fit ​​structure effectively shortens the replacement time of the guide flap 2, saving replacement time compared to traditional welding or bolt connection methods, and significantly reducing downtime caused by wear or specification adjustment of the guide flap 2. By replacing the guide flap 2 with different lengths and angles, and cooperating with the positioning scale adjustment of the snap-fit ​​base 121, it can adapt to the packing needs of more irregularly shaped cartons or special materials, solving the problem of poor versatility of traditional fixed connection structures.

[0094] In this embodiment, the guide cover 2 includes a first plate 21 and a second plate 22. The first plate 21 is snapped onto the snap-fit ​​seat 121, and the second plate 22 is disposed on one side of the first plate 21 and facing the packing position. The second plate 22 and the first plate 21 are disposed at an angle A.

[0095] The angle design between the first plate 21 and the second plate 22 allows the guide flap 2 to better fit the natural opening angle of the carton flap. Combined with the guiding effect of the second plate 22, it can reduce the impact force when materials come into contact, and avoid the material bouncing or jamming phenomenon that may occur in traditional straight structures.

[0096] Example 5

[0097] This embodiment is an improvement on the optical aspects of Embodiment 1.

[0098] like Figures 1-6 As shown, in this embodiment, a box-pushing structure is also included. The box-pushing structure includes a driving device 42, a guide structure, and a box-pushing plate 41. The box-pushing plate 41 is disposed at the box-packing position, and the guide structure is disposed below the box-packing position. The box-pushing plate 41 is slidably disposed on the guide structure. The driving device 42 is fixed on the frame 1, and the output end of the driving device 42 drives the box-pushing plate 41 to move on the guide structure 43.

[0099] Furthermore, the guide structure 43 includes a guide rail 431 and a mounting base 432, and a pulley 4321 is provided on the mounting base 432, the pulley 4321 being slidably engaged with the guide rail 431;

[0100] The output end of the drive device 42 is fixedly connected to the mounting base 432, and the push box plate 41 is disposed on the mounting base 432.

[0101] The pusher plate 41 is made of cold-rolled steel plate and bent into an arc shape. The horizontal pushing surface dimension of the pusher plate 41 is adapted to the width of the carton. A 5mm thick EVA cushioning pad is pasted on the pushing surface of the pusher plate 41 to prevent damage to the carton surface during pushing. The guide structure 43 includes two parallel guide rails 431 and a sliding mounting base 432. The guide rails 431 are SBR16 linear guide rails and are fixed to the crossbeam of the frame 1 below the packing position in a direction perpendicular to the conveyor line. The mounting base 432 is a welded steel structure. The bottom is equipped with pulleys 4321 through four deep groove ball bearings. The pulleys 4321 are clearance-fitted with the guide rails 431 (fit clearance 0.1-0.3mm), and the sliding resistance is ≤10N. The top of the mounting base 432 is detachably connected to the pusher plate 41 by bolts, which facilitates the replacement of pusher plates of different specifications.

[0102] The drive unit 42 uses a standard cylinder of model SC80×1500. The cylinder body is mounted on the column of the frame 1, and the piston rod end is rigidly connected to the mounting base 432 through a floating joint. The cylinder is equipped with a flow control valve, which can adjust the pushing speed (0.1-0.5m / s adjustable).

[0103] In this embodiment, the guiding device operates as follows: After the material is packed, the control system receives a packing completion signal; the drive device 42 (cylinder) is ventilated, and the piston rod extends to push the mounting base 432 to slide along the guide rail 431; the pusher plate 41 moves synchronously with the mounting base 432, and after contacting the carton, pushes it from the packing position to the downstream conveyor line; after being pushed into place, the cylinder piston rod retracts, driving the pusher plate 41 to reset to the initial position, waiting for the next pusher command.

[0104] The box-pushing structure and guiding device work together to automate the entire process from material loading to box transfer, completely replacing manual box-pushing operations and reducing labor costs.

[0105] Example 6

[0106] like Figures 1-6 As shown, this embodiment provides a packing system, which includes a robotic arm and a packing guide device as described above.

[0107] Specifically, the robotic arm is a six-axis industrial robot equipped with an adaptive vacuum suction cup gripper that can automatically adjust the gripping angle according to the shape of the material. The robotic arm is fixed on the side frame 1 of the packing guide device, and its working radius covers the entire path from the material buffer area to the packing position.

[0108] When the system is working:

[0109] The carton is conveyed to the packing position via a conveyor line. Once the infrared sensor detects its position, it sends a signal to the central control system, and the conveyor line pauses. Simultaneously, a robotic arm grabs the product to be packed (such as an air conditioner indoor unit) from the material buffer area, correcting its gripping posture through visual positioning. The robotic arm carries the material to directly above the packing position. During its vertical descent, the bottom of the material contacts the second plate 22 of the guide cover 2, forcing the guide cover 2 to rotate around the mounting tube 12 and open the carton cover. Under the action of the spring's restoring force, the guide cover 2 remains in contact with the material surface, correcting placement deviations and buffering impacts.

[0110] After the material is completely placed into the carton, the robotic arm's suction cup releases and retracts, and the guide flap 2 returns to its initial angle under the action of the torsion spring and the limiting structure. After a 1-second delay, the central control system activates the carton-pushing structure, and the cylinder drives the pusher plate 41 to push the packed carton to the downstream sealing line. After the pusher plate 41 returns to its original position, the central control system sends a signal to the conveyor line, indicating that a new carton has entered the packing position. At the same time, the robotic arm grabs the next piece of material, and the next packing cycle begins.

[0111] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0112] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0113] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0114] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
