Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a vacuum suction cup gripping automated packaging machine. Background Technology

[0002] Automated packaging machines are key equipment in modern industrial production, integrating technologies such as mechanical transmission, sensor detection, and intelligent control. They can automatically complete processes such as material conveying, positioning, and packaging, and are widely used in industries such as food, pharmaceuticals, and daily necessities, improving packaging efficiency and quality.

[0003] Utility model patent CN221718982U discloses an automatic packaging machine. This automatic packaging machine includes a conveying device body and a packaging box placed on top of the conveying device body. Push rods are symmetrically installed on the side of the conveying device body, and push blocks are slidably installed on the side of the push rods to abut the packaging box. A support rod is installed adjacent to the side of the conveying device body, with a sealing plate installed on the bottom of the support rod. A suction cup is installed on the bottom of the sealing plate, used to absorb the cut adhesive strips and to dispense the packaging box. A moving device is installed between the sealing plate and the sealing device. When the sealing plate is adjusted to a suitable position, a second cylinder presses down on the sealing plate, causing it to adhere to the packaging box. Simultaneously, the air pump stops sucking air from the suction chamber, thus ensuring the adhesive strip adheres to the sealing area of ​​the packaging box, achieving a sealing effect. The machine has a simple structure and is easy to operate, sealing the packaging box through the cooperation of the air pump and suction cups.

[0004] When this automatic packaging machine uses suction cups to pick up and place lighter items, negative pressure sometimes remains inside the suction cups after the vacuum suction stops. This causes the lighter items to remain attached to the suction cups and not be able to detach in time, affecting packaging efficiency and the accuracy of item placement. In view of this, we propose a vacuum suction cup gripping automatic packaging machine. Utility Model Content

[0005] The purpose of this invention is to provide a vacuum suction cup gripping automated packaging machine to solve the problem mentioned in the background art where lighter items are still adsorbed by the residual negative pressure inside the suction cup.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vacuum suction cup gripping automated packaging machine includes a packaging machine body, on which are provided several material conveyor belts for conveying materials. The packaging machine body is also provided with a gripping robotic arm for gripping materials. The end of the gripping robotic arm is provided with a vacuum gripping mechanism. The vacuum gripping mechanism includes a movable cylinder installed at the top of the end of the gripping robotic arm, a movable seat installed at the end of the piston rod of the movable cylinder, and several separation components installed at the bottom of the movable seat.

[0008] The movable seat has a cavity inside, and several fixed tubes are connected to the bottom end of the movable seat. The bottom end of the fixed tubes is equipped with a suction cup, and an air pipe is connected to the outer end of the movable seat. The end of the air pipe is connected to an external vacuum device.

[0009] The separation assembly includes a fixed sleeve fixedly connected to the movable seat, a stop plate located below the fixed sleeve, and a spring disposed between the fixed sleeve and the stop plate. The top of the stop plate is provided with a sleeve post, which is sleeved on the inner side of the fixed sleeve and slidably connected to the fixed sleeve.

[0010] Preferably, the fixing tube is connected to the cavity, the suction cup is made of rubber material, and the bottom surface of the suction cup has a through hole that is connected to the fixing tube;

[0011] In this setup, a complete gas channel is formed through the connection between the fixed tube, cavity, and suction cup. The rubber suction cup with through holes ensures both sealing and gas flow during vacuum adsorption.

[0012] Preferably, an air pipe connector is installed on the outer end face of the movable seat, and the first end of the air pipe is connected to the air pipe connector;

[0013] In this setup, the connection between the air pipe connector and the air pipe ensures a stable connection between the movable seat and the external vacuum equipment.

[0014] Preferably, a plurality of vertical guide rods are fixed to the top of the movable seat, and the top of the guide rods passes through the gripping robotic arm and is slidably connected to the gripping robotic arm;

[0015] In this setup, the sliding engagement between the guide rod and the gripping robotic arm provides guidance for the movement of the movable seat, ensuring the smoothness and accuracy of the movement process.

[0016] Preferably, a top sleeve cavity is formed on the bottom surface of the fixed sleeve, the sleeve post extends into the top sleeve cavity, and the top end of the spring abuts against the top of the top sleeve cavity;

[0017] In this configuration, the top cavity provides space for the sleeve column, allowing the spring to be installed stably and providing elastic support for the movement of the stop plate.

[0018] Preferably, the top end of the sleeve column has a bottom sleeve cavity, and the bottom end of the spring abuts against the bottom of the bottom sleeve cavity;

[0019] In this configuration, the bottom sleeve cavity mates with the bottom end of the spring to further secure the spring and ensure the stability of the spring's elastic force.

[0020] Preferably, the outer peripheral surface of the fixing sleeve is provided with a plurality of waist-shaped grooves extending along its axial direction, and the outer peripheral surface of the sleeve post is provided with a plurality of protrusions corresponding to the waist-shaped grooves, the protrusions extending into the waist-shaped grooves.

[0021] In this configuration, the interlocking of the waist-shaped groove and the protruding column restricts the circumferential rotation of the sleeve column, making the movement direction of the abutment plate more stable.

[0022] Preferably, when no external force is applied, the abutment extends downward under the elastic force of the spring, so that the horizontal plane at the bottom of the abutment is lower than the horizontal plane at the bottom of the suction cup.

[0023] In this configuration, the structure ensures that the abutment contacts the placement surface before the suction cup, creating conditions for the material to be pushed off the suction cup by the spring force.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This vacuum suction cup gripping automated packaging machine, through its set separation component, ensures that when no external force is applied, the horizontal plane of the bottom of the abutment is lower than that of the bottom of the suction cup. During vacuum suction, the abutment can contact the surface of the item first, causing it to slide upward along the fixed sleeve to compress the spring. When vacuum suction stops, the abutment, under the elastic force of the spring, returns to its original shape and pushes the suctioned item downward, thus enabling lighter items to detach smoothly from the suction cup and preventing lighter items from being still held by the residual negative pressure inside the suction cup.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0037] Please see Figures 1-6 The vacuum suction cup gripping automated packaging machine includes a main body 100, which serves as the basic framework of the entire packaging machine, providing an installation and support platform for other structures. The main body 100 is equipped with several material conveyor belts 110 for transporting materials. These conveyor belts 110 can stably and orderly transport materials to designated positions, facilitating subsequent gripping and packaging operations. The main body 100 also features a gripping robotic arm 200 for gripping materials. The gripping robotic arm 200 can move flexibly in space to grip materials at different locations, expanding the working range of the packaging machine. The end of the gripping robotic arm 200 is equipped with a vacuum gripping mechanism 300. The vacuum gripping mechanism 300 includes a movable cylinder 310 installed at the top of the end of the gripping robotic arm 200, a movable seat 320 installed at the end of the piston rod of the movable cylinder 310, and several separation components 330 installed at the bottom of the movable seat 320. The movable cylinder 310 can drive the movable seat 320 to move up and down, providing power for the gripping and placement actions of the vacuum gripping mechanism 300. The movable seat 320 serves as a carrier connecting other components, playing a connecting role. The separation components 330 are the key structures for solving the problem of materials being difficult to detach after being adsorbed by the suction cup.

[0038] like Figures 2-4 As shown, in this invention, the movable seat 320 has a cavity 321 inside, which provides a channel for gas flow, facilitating cooperation with external vacuum equipment to achieve vacuum adsorption. Several fixed tubes 322 are connected to the bottom of the movable seat 320. Suction cups 323 are located at the bottom of the fixed tubes 322, which are connected to the cavity 321. The fixed tubes 322 connect the cavity 321 and the suction cups 323, allowing the negative pressure generated by the vacuum equipment to be transmitted to the suction cups 323, thus achieving material adsorption. The suction cups 323 are made of rubber, and their bottom surface has a through hole communicating with the fixed tubes 322. The rubber suction cups 323 have good sealing and flexibility, ensuring both adsorption effect and adaptability to material surfaces of different shapes. An air pipe connector 324 is installed on the outer end face of the movable seat 320. An air pipe 340 is connected to the outer end of the movable seat 320. The first end of the air pipe 340 is connected to the air pipe connector 324, and the second end of the air pipe 340 is connected to an external vacuum device. The air pipe connector 324 and the air pipe 340 form a gas transmission channel, connecting the external vacuum device to the cavity 321 inside the movable seat 320, thereby realizing the functions of vacuum adsorption and release.

[0039] like Figure 2 and Figure 4 As shown, specifically, the top of the movable seat 320 is fixed with several vertical guide rods 325. The top of the guide rods 325 passes through the gripping robotic arm 200 and is slidably connected to the gripping robotic arm 200. The guide rods 325 play a guiding role during the up and down movement of the movable seat 320, ensuring the stability and accuracy of the movement of the movable seat 320 and preventing deviation or shaking.

[0040] like Figure 5 and Figure 6 As shown, the separation assembly 330 further includes a fixed sleeve 331 fixedly connected to the movable seat 320, a stop plate 332 located below the fixed sleeve 331, and a spring 333 disposed between the fixed sleeve 331 and the stop plate 332. The top end of the fixed sleeve 331 is provided with a threaded post 3312, and the fixed sleeve 331 is threadedly installed on the bottom end of the movable seat 320 through the threaded post 3312. The top end of the stop plate 332 is provided with a sleeve post 3321, and a top sleeve cavity 3311 is opened on the bottom surface of the fixed sleeve 331. The sleeve post 3321 extends into the top sleeve cavity 3311, so that the sleeve post 3321 is sleeved on the inner side of the fixed sleeve 331 and slidably connected to the fixed sleeve 331. The fixed sleeve 331 provides a sliding track for the sleeve post 3321, and the spring 333 provides elastic force. The stop plate 332 can move up and down under the action of the spring 333. This structure can solve the problem of the material being difficult to detach after being adsorbed by the suction cup.

[0041] In addition, the outer peripheral surface of the fixed sleeve 331 is provided with several waist-shaped grooves 3313 extending along its axial direction, and the outer peripheral surface of the sleeve post 3321 is provided with several protrusions 3323 corresponding to the waist-shaped grooves 3313. The protrusions 3323 extend into the waist-shaped grooves 3313. The cooperation between the waist-shaped grooves 3313 and the protrusions 3323 restricts the circumferential rotation of the sleeve post 3321, ensuring that the abutment plate 332 maintains a stable posture during the up and down movement, so that the separation assembly 330 can work reliably and prevent the abutment plate 332 from detaching from the bottom of the fixed sleeve 331.

[0042] It is worth noting that the top of the sleeve 3321 has a bottom sleeve cavity 3322. The top of the spring 333 abuts against the top of the top sleeve cavity 3311, and the bottom of the spring 333 abuts against the bottom of the bottom sleeve cavity 3322. When no external force is applied, the abutment 332 extends downward under the elastic force of the spring 333, so that the horizontal plane of the bottom of the abutment 332 is lower than the horizontal plane of the bottom of the suction cup 323. When placing materials, the abutment 332 can contact the surface of the item before the suction cup 323, thereby compressing the spring 333. When the vacuum adsorption stops, the spring 333 returns to its original state and pushes the abutment 332 downward, causing the material to detach from the suction cup 323.

[0043] In this embodiment of the vacuum suction cup gripping automated packaging machine, the material is first transported to the designated position via the material conveyor belt 110, and the gripping robotic arm 200 moves above the material under the command of the control system. Then, the movable cylinder 310 drives the movable seat 320 to move downward, so that the suction cup 323 approaches the material. At the same time, the external vacuum equipment evacuates the cavity 321 through the air pipe 340 and the air pipe connector 324, so that the suction cup 323 generates negative pressure to adsorb the material. Next, the gripping robotic arm 200 moves the vacuum gripping mechanism 300 with the adsorbed material to the target placement position. Finally, when the vacuum gripping mechanism 300 reaches the target position, the abutment plate 332 first contacts the surface of the item and slides upward along the inner side of the fixed sleeve 331 through the sleeve column 3321, so that the abutment plate 332 compresses the spring 333, and then stops the vacuum adsorption. At this time, the spring 333 returns to its original state and pushes the abutment plate 332 downward, so that the material is smoothly separated from the suction cup 323 and placed in the target position.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
