Description

Technical Field

[0001] This utility model belongs to the technical field of packaging machine equipment, specifically relating to an accessory picking mechanism. Background Technology

[0002] Most kitchen paper towels and hand towels are now packaged in a bottom-pull-out style. However, this requires hanging the bottom-pull-out paper towel package on a wall or other vertical surface for easy hanging. Consumers need to prepare their own hooks when purchasing these paper products so they can hang them on the wall or the side of the refrigerator. To make it easier for consumers to use, a hook is usually placed inside the box when packaging the paper products. Consumers can directly take out the free hook when opening the package, which is convenient for consumers. However, the hooks are usually placed manually, which is labor-intensive.

[0003] Chinese patent document CN119190848A, published on December 27, 2024, discloses an invention patent entitled "An Adjustable Suction Cup Clamp," which includes a mounting flange; a first support plate connected to the mounting flange via multiple first pillars, with a first mounting space formed between the mounting flange and the first support plate; a second support plate connected to the first support plate via multiple second pillars, with a second mounting space formed between the second support plate and the first support plate; and a variable-pitch translation slide, including a base, a main shaft, sliding blocks, slide rails, and a drive motor. The main shaft and slide rails are mounted parallel to each other on the base. The outer wall of the main shaft is provided with multiple curved tracks. Multiple sliding blocks are slidably disposed on the slide rails and are respectively connected to the main shaft via the curved tracks. The drive motor is connected to the main shaft for transmission. When the main shaft rotates, it drives multiple sliders to translate along the slide rails, causing the spacing between the multiple sliders to change to open or close. The base is installed below the first support plate and passes downward through the second support plate, and the drive motor passes upward through... The first support plate is located within the first installation space; the adsorption assembly includes multiple suction cups, multiple connecting rods, and a vacuum generator. Each connecting rod is equipped with several suction cups and mounted on a sliding block of a variable-pitch translation slide. The connecting rod has an air passage that connects to the corresponding multiple suction cups. The air passage is connected to the vacuum generator through an air pipe. The vacuum generator is installed in the first installation space above the first support plate; the gripper assembly includes a gripper cylinder, a gripper support plate, a swing motor, a rotating rod, and swing arm claws. The gripper cylinder is installed in the first installation space on the first support plate. There are two gripper support plates, each connected to both ends of the gripper cylinder. Each gripper support plate is connected to the second support plate via a linear guide rail. A swing motor is installed above each gripper support plate, and a rotating rod is installed below each gripper support plate via two supports. Each rotating rod is fixedly equipped with two swing arm claws. The swing motor is connected to the rotating rod for transmission. When the swing motor drives the rotating rod to rotate, it drives the two swing arm claws to swing.

[0004] The aforementioned prior art uses multiple suction cups with adjustable spacing via a variable-pitch translation slide to pick up materials of different sizes and shapes. The swing arm claw can adjust the overall spacing via a gripper cylinder and then achieve a rotating gripping effect via a swing motor. It can also work with the adsorption components to pick up materials of different sizes and shapes, thus enabling the fixture to grip materials of different sizes and shapes as a whole.

[0005] However, the aforementioned existing technologies are complex in structure and have high equipment costs, making them unsuitable for picking up a single hook. Utility Model Content

[0006] To address the shortcomings of the existing technology, this utility model provides a parts picking structure. Its purpose is to propose a parts picking mechanism with a simple structure and low equipment cost, which can place parts without relying on manual placement (adhesive hooks or hooks), thereby reducing labor costs.

[0007] This utility model is achieved through the following technical solution:

[0008] This utility model proposes an accessory picking mechanism, including a mounting plate. The bottom two ends of the mounting plate are respectively provided with openable and closable claw assemblies, and a vacuum suction cup assembly is provided between the claw assemblies at both ends. The vacuum suction cup assembly is assembled on the mounting plate through a telescopic component, and the telescopic component drives the vacuum suction cup assembly to perform a vertical telescopic movement. The opening and closing direction of the claw assembly is perpendicular to the direction in which the telescopic component drives the vacuum suction cup assembly to perform a vertical telescopic movement.

[0009] The claw assembly includes a bidirectional telescopic cylinder, a first claw component, and a second claw component. The first claw component and the second claw component are arranged opposite to each other. The upper end of the first claw component is connected to the telescopic end of one end of the bidirectional telescopic cylinder, and the upper end of the second claw component is connected to the telescopic end of the other end of the bidirectional telescopic cylinder. The bidirectional telescopic cylinder drives the first claw component and the second claw component to open and close.

[0010] More preferably, the bottom of the first and second claw components is bent into an arc-shaped bend, and when the claw assembly is working, the arc-shaped bend comes into contact with the material inside the packaging box.

[0011] More preferably, a rotary drive assembly is mounted on the mounting plate. The rotary drive assembly includes a rotary mounting base, a rotary drive motor, and a rotary shaft. The rotary mounting base is mounted on the mounting plate, the rotary drive motor is fixedly mounted on the rotary mounting base, and the rotary shaft is rotatably mounted on the rotary mounting base. The rotary drive motor drives the rotary shaft to rotate through a transmission assembly. The rotary shaft is fixed to the mounting plate.

[0012] More preferably, the transmission assembly includes a synchronous belt, a driving synchronous pulley, and a driven synchronous pulley. The driving synchronous pulley is mounted on the motor shaft of the rotary drive motor, and the driven synchronous pulley is mounted on the rotating shaft to tension the synchronous belt.

[0013] More preferably, the transmission assembly includes a driving gear and a driven gear, with the driving gear mounted on the motor shaft of the rotary drive motor and the driven gear mounted on the rotating shaft, and the driving gear meshing with the driven gear.

[0014] More preferably, the vacuum suction cup assembly includes two vacuum suction cups.

[0015] More preferably, the upper ends of the first and second claw components are inclined outwards, and the lower ends are inclined inwards.

[0016] The second aspect of this utility model provides an apparatus for placing accessories into a packaging box, including an accessory sorting mechanism, a packaging box conveying mechanism, a motion execution mechanism, and the accessory picking mechanism described in the first aspect. The accessory sorting mechanism is disposed on one side of the packaging box conveying mechanism and is configured to sort the accessories one by one and output the accessories to be placed into the packaging box. The packaging box conveying mechanism is configured to convey an unsealed packaging box containing materials. The accessory picking mechanism is mounted on the motion execution mechanism, which includes at least one horizontal reciprocating degree of freedom and one vertical reciprocating degree of freedom. The motion execution mechanism is configured to drive the accessory picking mechanism to move to the output end of the accessory sorting mechanism to pick up the accessories and place the picked-up accessories into the packaging box conveyed by the packaging box conveying mechanism.

[0017] More preferably, the motion actuator is a two-axis parallel manipulator, an XY-axis motion assembly, a cross-shaped parallel robot, or a three-axis delta robot.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This device requires no human intervention throughout the entire process, replacing the traditional method of manually placing hooks. This reduces reliance on manual labor, thereby lowering labor costs. It also avoids potential errors that may occur during manual operation, thus improving production efficiency and stability.

[0020] 2. The gripper assembly of the bidirectional telescopic cylinder can separate adjacent materials in the packaging box to form a gap. This gap can accommodate the hook body, so that the hook body is clamped between adjacent materials. On the one hand, it ensures the stability of the hook; on the other hand, it ensures that the height of the material is not affected after the hook is placed; and thirdly, it also avoids the hook body damaging the packaging film of the material. The telescopic component drives the vacuum suction cup assembly to perform a vertical telescopic action. The vacuum suction cup assembly is responsible for picking up and placing the hook, and the vacuum suction cup assembly holds the hook stably and reliably, preventing the hook from falling off during the picking and placing process.

[0021] 3. The bottom of the mounting plate is equipped with openable and closable claw components at both ends, which can simultaneously separate the two ends of adjacent materials, thus forming a more stable gap and avoiding the material being subjected to force on one side, which would prevent the gap from being formed.

[0022] 4. The opening and closing actions of the first and second claw components driven by the bidirectional telescopic cylinder do not interfere with the vertical telescopic action of the vacuum suction cup driven by the telescopic component, thus avoiding motion interference.

[0023] 5. The rotary drive motor drives the mounting plate to rotate, adjusting the parts picking mechanism to adapt to the arrangement direction of materials in different packaging boxes, thus enhancing the equipment's adaptability to different working conditions.

[0024] 6. The bottom of the first and second claws is bent to form an arc-shaped bend. When the claw assembly is working, the arc-shaped bend comes into contact with the material inside the packaging box, reducing pressure or scratching on the material packaging and preventing damage to the packaging film.

Detailed Implementation

[0028] Example 1

[0029] like Figure 2 As shown, this utility model proposes an accessory picking mechanism, including a mounting plate 1. Openable and closable claw assemblies are respectively provided at both ends of the bottom of the mounting plate 1. A vacuum suction cup assembly 2 is provided between the claw assemblies at both ends. The vacuum suction cup assembly 2 is mounted on the mounting plate 1 via a telescopic member 3. The telescopic member 3 drives the vacuum suction cup assembly 2 to perform a vertical telescopic movement. The opening and closing direction of the claw assembly is perpendicular to the direction in which the telescopic member 3 drives the vacuum suction cup assembly 2 to perform a vertical telescopic movement.

[0030] The claw assembly includes a bidirectional telescopic cylinder 4, a first claw component 5, and a second claw component 6. The first claw component 5 and the second claw component 6 are arranged opposite to each other. The upper end of the first claw component 5 is connected to the telescopic end of one end of the bidirectional telescopic cylinder 4, and the upper end of the second claw component 6 is connected to the telescopic end of the other end of the bidirectional telescopic cylinder 4. The first claw component 5 and the second claw component 6 are driven to open and close by the bidirectional telescopic cylinder 4.

[0031] During implementation, when the first claw 5 and the second claw 6 come into contact with the materials, the first claw 5 contacts one material and the second claw 6 contacts another material. The bidirectional telescopic cylinder 4 drives the first claw 5 and the second claw 6 to extend outward, separating the two adjacent materials to form a gap that can accommodate the hook body of the hook 10. The telescopic component 3 drives the vacuum suction cup assembly 2 to extend vertically, placing the suction hook 10 in the gap, so that the hook body is clamped between the adjacent materials. On the one hand, this ensures the stability of the hook 10, on the other hand, it ensures that the placement of the hook 10 will not affect the height of the materials, and thirdly, it also avoids the hook body of the hook 10 from damaging the packaging film of the materials.

[0032] The vacuum suction cup assembly 2 includes two vacuum suction cups. When the hook is picked up by the two vacuum suction cups, it is more stable and the hook is less likely to fall off.

[0033] The telescopic component 3 is a telescopic air cylinder or a telescopic hydraulic cylinder.

[0034] Example 2

[0035] This embodiment is a further detailed description and supplement to the implementation of this utility model based on Embodiment 1.

[0036] The bottom of the first claw component 5 and the second claw component 6 are bent to form an arc-shaped bend 7. When the claw assembly is working, this arc-shaped bend 7 comes into contact with the material inside the packaging box, thus preventing damage to the packaging film.

[0037] More preferably, the upper ends of the first claw 5 and the second claw 6 are inclined outwards, and the lower ends are inclined inwards. On the one hand, this arrangement allows the arc-shaped bends 7 at both ends to contact the straight edge formed by the contact of adjacent materials, which is beneficial for separating the two materials. On the other hand, it increases the contact area between the arc-shaped bends 7 and the materials. Compared with the vertical arrangement, the bottom end of the arc-shaped bends 7 makes point contact with the materials. By tilting the arrangement, the contact area between the arc-shaped bends 7 and the materials is increased, and when the bidirectional telescopic cylinder 4 drives the first claw 5 and the second claw 6 to separate adjacent materials, a gap is formed more stably.

[0038] Example 3

[0039] This embodiment is a further detailed description and supplement to the implementation of this utility model based on embodiment 1 or embodiment 2.

[0040] It also includes a rotary drive assembly, which includes a rotary mounting base 8, a rotary drive motor 9, and a rotary shaft. The rotary mounting base 8 is mounted on the mounting plate 1, the rotary drive motor 9 is fixedly mounted on the rotary mounting base 8, and the rotary shaft is rotatably mounted on the rotary mounting base 8. The rotary drive motor 9 drives the rotary shaft to rotate through a transmission assembly. The rotary shaft is fixed to the mounting plate 1.

[0041] More preferably, the transmission assembly includes a synchronous belt, a driving synchronous pulley, and a driven synchronous pulley. The driving synchronous pulley is mounted on the motor shaft of the rotary drive motor 9, and the driven synchronous pulley is mounted on the rotating shaft to tension the synchronous belt. When the rotary drive motor 9 is energized, its motor shaft rotates, and the driving synchronous pulley rotates with the motor shaft, thereby driving the synchronous belt to move. Since the synchronous belt is a closed loop, the rotation of the driving synchronous pulley is converted into the loop motion of the synchronous belt, which in turn drives the driven synchronous pulley to rotate. When the driven synchronous pulley is driven to rotate by the synchronous belt, the rotating shaft rotates together with the driven synchronous pulley, realizing the rotation of the mounting plate 1.

[0042] More preferably, the transmission assembly includes a driving gear and a driven gear. The driving gear is mounted on the motor shaft of the rotary drive motor 9, and the driven gear is mounted on the rotating shaft. The driving gear and the driven gear mesh. When the rotary drive motor 9 is powered on, its motor shaft rotates, and the driving gear rotates with the motor shaft. Because the driving gear and the driven gear mesh, the driven gear is driven to rotate, and the rotating shaft rotates together with the driven gear, thereby realizing the rotation of the mounting plate 1.

[0043] Example 4

[0044] This embodiment further elaborates and supplements the implementation of this utility model based on Embodiment 3.

[0045] like Figure 1 As shown, the second aspect of this utility model provides an apparatus for placing accessories into a packaging box, including an accessory sorting mechanism 11, a packaging box conveying mechanism 12, a motion execution mechanism 13, and an accessory picking mechanism 14 as described in the above embodiment. The accessory sorting mechanism 11 is disposed on one side of the packaging box conveying mechanism 12 and is configured to sort the accessories one by one and output the accessories to be placed into the packaging box. The packaging box conveying mechanism 12 is configured to convey an unsealed packaging box containing materials. The accessory picking mechanism 14 is mounted on the motion execution mechanism 13. The motion execution mechanism 13 includes at least one horizontal reciprocating degree of freedom and one vertical reciprocating degree of freedom. The motion execution mechanism 13 is configured to drive the accessory picking mechanism 14 to move to the output end of the accessory sorting mechanism 11 to pick up the accessories and place the picked-up accessories into the packaging box conveyed by the packaging box conveying mechanism 12.

[0046] As an example, if the material arrangement direction inside the packaging box (i.e., the straight line formed by the contact between adjacent materials) is perpendicular to the opening and closing direction of the claw assembly, then it is not necessary to assemble a rotary drive assembly at the moving end of the motion actuator 13; the accessory picking mechanism 14 is assembled on the moving end of the motion actuator 13.

[0047] In practice, hook 10 is conveyed to the output end of accessory sorting mechanism 11. Accessory picking mechanism 14 moves to the output end of accessory sorting mechanism 11 via motion actuator 13. Telescopic component 3 drives vacuum suction cup assembly 2 to extend vertically, suck up hook 10, and then retracts. Motion actuator 13 drives accessory picking mechanism 14 to move above an unsealed packaging box containing materials, and the claw assembly contacts the materials. Claw assemblies at both ends of the bottom of mounting plate 1 extend outward, separating adjacent materials to form a gap to accommodate the hook body of hook 10. Telescopic component 3 drives vacuum suction cup assembly 2 to extend vertically, placing the hook body of hook 10 in the gap, so that the hook body is clamped between two adjacent materials. Motion actuator 13 drives accessory picking mechanism 14 to move to the output end of accessory sorting mechanism 11. During the movement, telescopic component 3 drives vacuum suction cup assembly 2 to retract to its original position, and claw assembly retracts to its original position. The above actions are repeated to achieve the picking and placing of hook 10.

[0048] As another example, if the material arrangement direction inside the packaging box (i.e. the straight line formed by the contact between adjacent materials) is not perpendicular to the opening and closing direction of the claw assembly, a rotary drive assembly needs to be installed at the moving end of the motion actuator 13. The rotary drive assembly rotates the accessory picking mechanism 14 so that the opening and closing direction of the claw assembly is perpendicular to the straight line formed by the contact between adjacent materials.

[0049] The motion actuator 13 is equipped with a rotary drive assembly at its moving end, and the mounting plate 1 is mounted on the rotary drive assembly.

[0050] During implementation, hook 10 is conveyed to the output end of accessory sorting mechanism 11. Accessory picking mechanism 14 moves to the output end of accessory sorting mechanism 11 via motion actuator 13. Telescopic component 3 drives vacuum suction cup assembly 2 to extend vertically to suck up hook 10 and then retracts. Motion actuator 13 drives accessory picking mechanism 14 to move above an unsealed packaging box containing materials. During the process of moving above the unsealed packaging box containing materials, rotation drive assembly drives accessory picking mechanism 14 to rotate, so that the opening and closing direction of the claw assembly contacts the adjacent materials. With the straight line perpendicular, the claw assembly contacts the material. The claw assemblies at both ends of the bottom of the mounting plate 1 extend outward, separating adjacent materials to form a gap to accommodate the hook body of the hook 10. The telescopic component 3 drives the vacuum suction cup assembly 2 to extend vertically, placing the hook body of the hook 10 in the gap, so that the hook body is clamped between two adjacent materials. The motion execution mechanism 13 drives the accessory picking mechanism 14 to move to the output end of the accessory sorting mechanism 11. During the movement, the telescopic component 3 drives the vacuum suction cup assembly 2 to retract to its original position, the claw assembly retracts to its original position, and the rotation drive assembly drives the accessory picking mechanism 14 to reset. The above actions are repeated to realize the picking and placing of the hook 10.

[0051] More preferably, the motion actuator 13 is a two-axis parallel manipulator, an XY-axis motion assembly, a cross-shaped parallel robot, or a three-axis delta robot.

[0052] In this embodiment, both the motion actuator 13 and the accessory feeding mechanism 11 are existing devices, and their structures are not limited in this embodiment.
