Description

Technical Field

[0001] This utility model relates to the field of packaging box assembly technology, specifically a rapid assembly structure for packaging boxes. Background Technology

[0002] Traditional packaging box assembly methods, especially for types where the box body and lid are separate, primarily rely on manual operation, where the lid is manually placed on the box body. In large-scale production scenarios, this manual assembly method reveals numerous drawbacks: manual operation is time-consuming and labor-intensive, requiring significant investment of manpower and time, resulting in extremely low packaging box assembly efficiency and failing to meet the demands of high-efficiency production. Furthermore, consistency in manual operation is difficult to guarantee; differences in operating habits and force among different workers easily lead to inconsistent packaging box assembly quality, resulting in problems such as loose fit between the lid and box body, thus reducing the overall quality of the product packaging.

[0003] To improve packaging box assembly efficiency and reduce labor costs, a series of automated or semi-automated assembly equipment and technologies have emerged in the industry. Some equipment uses conveyor belts to transport boxes and is equipped with sorting, pressing, and feeding mechanisms to automatically press the box lids onto the boxes. However, these existing devices still have some shortcomings in practical applications. For example, some equipment has a complex structure and high maintenance costs, which can impose a significant economic burden on small and medium-sized enterprises (SMEs). Some equipment has poor adaptability, only capable of assembling packaging boxes of specific sizes and shapes, failing to meet the diverse packaging box assembly needs of the market. Furthermore, some equipment lacks precision in positioning the box lids and boxes during assembly, easily leading to assembly deviations and affecting the quality of the packaging boxes. Utility Model Content

[0004] In order to solve the problems in related technologies, this utility model provides a quick assembly structure for packaging boxes. This device solves the problems of time-consuming and labor-intensive manual operation and complex equipment structure.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] This utility model discloses a rapid assembly structure for packaging boxes, comprising two parallel support plates arranged vertically. A box conveyor belt for transporting the box body is provided between the two support plates. A support rod is movably mounted on the support plate, and a placement plate for positioning the box lid is fixedly mounted on the upper end of the support rod. The placement plate is located above the box conveyor belt and has a placement hole slightly larger than the box lid. A drive mechanism for driving the support rod to move vertically is provided on the lower end of the support rod. A column is provided on the support plate at one end of the placement plate, and a robotic arm for gripping the box lid is mounted on the column. A pressure roller mechanism is provided on the support plate at the other end of the placement plate.

[0007] By adopting the above solution, the box conveyor belt enables continuous automatic transport of boxes, avoiding the time-consuming manual handling of boxes; the placement hole is slightly larger than the lid, thus achieving precise lid positioning and solving the problem of positional deviation when manually placing the lid; the robotic arm and pressure roller mechanism respectively handle the lid gripping and pressing after assembly, solving the problem of disjointed feeding and pressing in traditional manual assembly, realizing the entire process from box transport to finished product assembly, laying the foundation for automated operation. The placement plate is located above the box conveyor belt, with the robotic arm and pressure roller mechanism located at both ends of the placement plate, ensuring that lid positioning, gripping, and pressing are all completed directly above and in the extended area of ​​the box transport path, saving overall equipment space; at the same time, the components are arranged sequentially along the box transport direction, and the box can complete all assembly steps without turning or moving, avoiding transport jams caused by component misalignment and ensuring the continuity of the assembly process; thus solving the problems of time-consuming and labor-intensive manual operation and complex equipment structure.

[0008] Furthermore, the driving mechanism includes a first cylinder, the side wall of the first cylinder is fixedly connected to the inner wall of the support plate, a first fixing plate is fixedly provided on the lower end face of the support rod, a second fixing plate is fixedly provided on the piston rod of the first cylinder, the lower end face of the first fixing plate abuts against the upper end face of the second fixing plate, and the first fixing plate and the second fixing plate are fixedly connected.

[0009] In the above solution, the drive mechanism activates the first cylinder, and the piston rod of the first cylinder extends and retracts, precisely controlling the vertical movement distance of the support rod. This allows for adjustment of the placement plate height, ensuring that the lid and the box are always precisely aligned. This avoids problems such as the lid failing to close or the box being squeezed and deformed due to height deviation. The piston rod is rigidly connected to the support rod through a fixed plate, allowing the driving force to be evenly transmitted to the support rod. This ensures that the placement plate rises and falls smoothly without jamming or tilting, thus guaranteeing that the lid remains horizontal during height adjustment and preventing the lid from slipping or shifting due to tilting of the placement plate.

[0010] Furthermore, the pressure roller mechanism includes a second cylinder and a rotating shaft. A base is provided on each of the support plates, and a U-shaped groove is provided on the base. A roller is slidably disposed within the U-shaped groove. The rotating shaft is fixedly disposed between two rollers. A vertically arranged connecting rod is provided on the outer wall of each roller. The second cylinder is located on the base, and the connecting rod is fixedly connected to the piston rod of the second cylinder. A pressure roller body is fixedly sleeved on the outer wall of the rotating shaft, and a bearing is provided between the rotating shaft and the pressure roller body. A cover is provided over the second cylinder.

[0011] In the above scheme, the pressure roller mechanism allows the second cylinder to control the piston rod thrust by adjusting the air pressure, thereby adjusting the pressure of the pressure roller body on the lid. This prevents the pressure roller body from being fixed, which could cause deformation of thin lids or incomplete sealing of thick lids. The pressure roller body is connected to the rollers via a rotating shaft, achieving rolling sealing as the box is conveyed, which helps improve sealing. The rollers are slidably positioned within the U-shaped groove of the base, allowing the rotating shaft to drive the pressure roller body to slide up and down along the U-shaped groove. Combined with the drive of the second cylinder, the distance between the pressure roller body and the conveyor belt can be flexibly adjusted to accommodate boxes of different thicknesses without the need to replace the pressure roller assembly. Furthermore, the sliding fit between the rollers and the U-shaped groove is simple, and when the rollers or pressure roller body are worn, they can be directly removed from the U-shaped groove for easy replacement.

[0012] Furthermore, the robotic arm includes a horizontal movement mechanism, a vertical movement mechanism, and a gripping mechanism.

[0013] The above solution uses a robotic arm to grasp and transfer the box lid.

[0014] Furthermore, the horizontal moving mechanism includes a motor and an X-axis track; the X-axis track is fixedly mounted on the column, and a sliding block is provided on the X-axis track; the motor is used to drive the sliding block to slide along the X-axis track.

[0015] In the above solution, by setting up a horizontal moving mechanism, starting the motor, and cooperating with the X-axis track to guide and limit the movement of the sliding block, the movement of the sliding block can be precisely controlled, ensuring that the robot can accurately transfer the box cover to the top of the placement plate.

[0016] Furthermore, the vertical moving mechanism includes a third cylinder, which is fixedly mounted on the sliding block, and a mounting plate is fixedly connected to the output shaft of the third cylinder.

[0017] In the above solution, the vertical moving mechanism activates the third cylinder, and the piston rod of the third cylinder extends and retracts, thereby driving the mounting plate and the gripping mechanism below to move vertically. When assembling boxes of different heights or lids of different thicknesses, there is no need to replace the gripping mechanism. Simply adjusting the extension and retraction of the third cylinder ensures that the gripping mechanism can accurately contact the lid when gripping or adapt to the height of the box when closing, greatly improving the equipment's adaptability to diverse packaging boxes.

[0018] Furthermore, the gripping mechanism includes at least one gripper, a slide bar is provided on the mounting plate, the gripper is located on the slide bar, a fourth cylinder is provided on one side of the slide bar for driving the gripper to slide along the slide bar, and an electromagnet for picking up the lid is provided below the gripper.

[0019] In the above solution, the gripper is driven by the fourth cylinder to move along the slide bar, and the opening and closing range can be adjusted according to the size of the lid. At the same time, the electromagnet below the gripper generates magnetic force after being energized, which can attract and fix the lid, and can stably grip even if the lid surface is smooth.

[0020] The above solution has the following advantages:

[0021] This invention provides a rapid assembly structure for packaging boxes. The box conveyor belt enables continuous automatic transport of the boxes, eliminating the time-consuming manual handling. The placement hole is slightly larger than the lid, ensuring precise lid positioning and resolving the issue of lid misalignment during manual placement. A robotic arm and pressure roller mechanism respectively grip the lid and press it into place after assembly, solving the problem of disjointed feeding and pressing in traditional manual assembly. This achieves a complete process from box transport to finished product assembly, laying the foundation for automated operation. The placement plate is located above the box conveyor belt, with the robotic arm and pressure roller mechanism positioned at opposite ends. This ensures that lid positioning, gripping, and pressing are all completed directly above and within the extended area of ​​the box transport path, saving overall equipment space. Furthermore, the components are arranged sequentially along the box transport direction, allowing the box to complete all assembly steps without turning or shifting, avoiding transport delays caused by component misalignment and ensuring the continuity of the assembly process.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In specific embodiment 1, such as Figures 1-5 As shown, a quick assembly structure for a packaging box according to this utility model includes two parallel support plates 1 arranged vertically. A box conveyor belt 2 for conveying the box body 27 is provided between the two support plates 1. A support rod 3 is movably provided on the support plate 1. A placement plate 4 for positioning the box cover 28 is fixedly provided on the upper end face of the support rod 3. The placement plate 4 is located above the box conveyor belt 2. A placement hole 5 is provided on the placement plate 4, which is slightly larger than the box cover 28. A drive mechanism for driving the support rod 3 to move vertically is provided on the lower end face of the support rod 3. A column 6 is provided on the support plate 1 at one end of the placement plate 4. A robotic arm for gripping the box cover 28 is provided on the column 6. A pressure roller mechanism is provided on the support plate 1 at the other end of the placement plate 4. The box conveyor belt 2 enables continuous automatic transport of the box 27, avoiding the time-consuming manual handling of the box 27. The placement hole 5 is slightly larger than the lid 28, thus achieving precise positioning of the lid 28 and solving the problem of positional deviation when manually placing the lid 28. The robotic arm and pressure roller mechanism respectively grip the lid 28 and press it after assembly, solving the problem of disjointed feeding and pressing in traditional manual assembly, realizing the entire process from transporting the box 27 to the finished product assembly, laying the foundation for automated operation. The placement plate 4 is located above the box conveyor belt 2, and the robotic arm and pressure roller mechanism are located at both ends of the placement plate 4, so that the positioning, gripping, and pressing of the lid 28 are all completed directly above and in the extended area of ​​the box 27's transport path, saving the overall space occupied by the equipment. At the same time, the components are arranged sequentially along the transport direction of the box 27, and the box 27 can complete all assembly steps without turning or moving, avoiding transport jams caused by component misalignment and ensuring the continuity of the assembly process.

[0031] like Figure 2 As shown, the driving mechanism includes a first cylinder 7. The side wall of the first cylinder 7 is fixedly connected to the inner wall of the support plate 1. A first fixing plate 8 is fixedly installed on the lower end of the support rod 3. A second fixing plate 9 is fixedly installed on the piston rod of the first cylinder 7. The lower end of the first fixing plate 8 abuts against the upper end of the second fixing plate 9, and the first fixing plate 8 and the second fixing plate 9 are fixedly connected. When the first cylinder 7 is activated, the piston rod of the first cylinder 7 extends and retracts, which can precisely control the vertical movement distance of the support rod 3, thereby adjusting the height of the placement plate 4. This allows for adjustment according to the height of the box 27, ensuring that the lid 28 and the box 27 are always precisely aligned, avoiding problems such as the lid 28 failing to close or the box 27 being squeezed and deformed due to height deviation. The piston rod is rigidly connected to the support rod 3 through the fixing plate, and the driving force can be evenly transmitted to the support rod 3, ensuring that the placement plate 4 rises and falls smoothly without jamming or tilting. This ensures that the lid 28 remains horizontal during height adjustment, preventing the lid 28 from slipping or shifting due to tilting of the placement plate 4.

[0032] like Figure 3 As shown, the pressure roller mechanism includes a second cylinder 10 and a rotating shaft 11. A base 12 is provided on each support plate 1, and a U-shaped groove 13 is provided on the base 12. Rollers 14 are slidably arranged within the U-shaped groove 13. The rotating shaft 11 is fixedly positioned between the two rollers 14. A vertically arranged connecting rod 15 is provided on the outer wall of the rollers 14. The second cylinder 10 is located on the base 12, and the connecting rod 15 is fixedly connected to the piston rod of the second cylinder 10. A pressure roller body 16 is fixedly sleeved on the outer wall of the rotating shaft 11, and a bearing 17 is provided between the rotating shaft 11 and the pressure roller body 16. A cover is provided over the second cylinder 10. The second cylinder 10 can control the piston rod thrust by adjusting the air pressure, thereby adjusting the pressure of the pressure roller body 16 on the lid 28, preventing the pressure of the pressure roller body 16 from being fixed, which would cause deformation of thin lids and loose sealing of thick lids. The pressure roller body 16 is connected to the rollers 14 via the rotating shaft 11, and achieves rolling pressing as it is conveyed with the box body 27, which helps improve sealing. The roller 14 is slidably disposed in the U-shaped groove 13 of the base 12, so that the rotating shaft 11 can drive the pressure roller body 16 to slide up and down along the U-shaped groove 13. With the help of the second cylinder 10, the distance between the pressure roller body 16 and the conveyor belt can be flexibly adjusted to adapt to boxes 27 of different thicknesses without the need to replace the pressure roller assembly. At the same time, the sliding engagement structure between the roller 14 and the U-shaped groove 13 is simple. When the roller 14 or the pressure roller body 16 is worn, it can be directly removed from the U-shaped groove 13 for easy replacement.

[0033] like Figure 4 , 5 As shown, the robotic arm includes a horizontal movement mechanism, a vertical movement mechanism, and a gripping mechanism.

[0034] The horizontal moving mechanism includes a motor 18 and an X-axis track 19. The X-axis track 19 is fixedly mounted on the column 6, and a sliding block 20 is mounted on the X-axis track 19. The motor 18 drives the sliding block 20 to slide along the X-axis track 19. When the motor 18 is turned on, in conjunction with the X-axis track 19 to guide and limit the movement of the sliding block 20, the movement of the sliding block 20 can be precisely controlled, ensuring that the robotic arm can accurately transfer the lid 28 to the top of the placement plate 4.

[0035] The vertical movement mechanism includes a third cylinder 21, which is fixedly mounted on the sliding block 20. A mounting plate 22 is fixedly connected to the output shaft of the third cylinder 21. When the third cylinder 21 is activated, its piston rod extends and retracts, thereby driving the mounting plate 22 and the gripping mechanism below to move vertically. When assembling boxes 27 of different heights or lids 28 of different thicknesses, there is no need to replace the gripping mechanism. Simply adjusting the extension and retraction of the third cylinder 21 ensures that the gripping mechanism can accurately contact the lid 28 when gripping or adapt to the height of the box 27 when closing, greatly improving the equipment's adaptability to diverse packaging boxes.

[0036] The gripping mechanism includes at least one gripper 23. A slide bar 24 is provided on the mounting plate 22, and the gripper 23 is located on the slide bar 24. A fourth cylinder 25 is provided on one side of the slide bar 24 to drive the gripper 23 to slide along the slide bar. An electromagnet 26 is provided below the gripper 23 to pick up the lid 28. The gripper 23 is driven by the fourth cylinder 25 to move along the slide bar 24, and the opening and closing range can be adjusted according to the size of the lid 28. At the same time, the electromagnet 26 below the gripper 23 generates a magnetic force when energized, which attracts and fixes the lid 28, so that it can be gripped stably even if the surface of the lid 28 is smooth.

[0037] During operation, the equipment parameters are pre-adjusted according to the size of the packaging box to be assembled. The height of the support rod 3 is adjusted by the first cylinder 7 so that the placement plate 4 is at the horizontal height of the box cover 28. At the same time, the initial air pressure of the second cylinder 10 is adjusted to ensure that the initial distance between the pressure roller body 16 and the box conveyor belt 2 meets the subsequent pressing requirements.

[0038] The box conveyor belt 2 is activated, and it drives the box 27 to move at a constant speed along the channel between the two support plates 1 towards the pressure roller mechanism. When the box 27 is about to reach the area directly below the placement plate 4, the motor 18 is activated. The motor 18 drives the sliding block 20 to slide along the X-axis track 19 on the column 6, moving the entire robot arm horizontally to the position of the initial box cover 28, ensuring that the gripping mechanism is aligned with the position of the box cover 28. The third cylinder 21 is activated, and its piston rod extends downward, driving the mounting plate 22 and the gripping mechanism below it to descend vertically until the gripper 23 of the gripping mechanism and the electromagnet 26 are close to the box. When the lid 28 is lifted, the electromagnet 26 is energized to generate a magnetic force, which attracts the lid 28. After the lid 28 is grasped, the piston rod of the third cylinder 21 of the vertical moving mechanism retracts upward, driving the grasping mechanism and the lid 28 to rise vertically in sync. Then the horizontal moving mechanism starts again, and the motor 18 drives the sliding block 20 to slide in the opposite direction along the X-axis track 19, transferring the grasped lid 28 to the top of the placement plate 4 and precisely aligning it with the position of the box body 27 conveyed from the area directly below the placement plate 4. The electromagnet 26 is de-energized to cancel the magnetic attraction, and the lid 28 falls vertically from the placement hole 5 onto the box body 27, completing the initial closing action.

[0039] After the initial sealing of the box body 27 and the lid 28 is completed, they move towards the pressure roller mechanism along the box body conveyor belt 2. When they reach below the pressure roller body 16, the second cylinder 10 is activated. The piston rod of the second cylinder 10 pushes the connecting rod 15, causing the roller 14 to slide downward along the U-shaped groove 13 of the base 12, so that the pressure roller body 16 is in contact with the surface of the lid 28. As the box body conveyor belt 2 continues to convey, the lid 28 drives the pressure roller body 16 to rotate around the rotating shaft 11. The pressure roller body 16 applies uniform pressure to the lid 28, pressing the lid 28 tightly with the box body 27. The finished packaging box, after being pressed by the pressure roller mechanism, continues to move with the box body conveyor belt 2 and is finally output from the discharge end of the box body conveyor belt 2, thus completing the rapid assembly process of the entire packaging box.
