[0020] 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.

[0021] like Figure 1 and Figure 3As shown, in this embodiment, the present invention includes an opening assembly 1 and a limiting conveyor belt 2. The opening assembly 1 is used to open product components and limit them on the limiting conveyor belt 2. The opening assembly 1 includes a first frame 10, a first driving component 11, a first slide rail 12, and a product limiting frame 13. The first driving component 11, the first slide rail 12, and the product limiting frame 13 are all mounted on the first frame 10. The product limiting frame 13 is slidably engaged with the first slide rail 12. The first driving component 11 is used to push the product limiting frame 13 to reciprocate. The product limiting frame 13 is provided with at least one gripping component 14, which is used to limit the product components. Therefore, the first frame 10 provides support and fixation for the first drive component 11, the first slide rail 12, and the product limiting frame 13. The first drive component 11 serves as a power source, providing drive to the product limiting frame 13. The first slide rail 12 guides the reciprocating motion of the product limiting frame 13, thereby ensuring the linearity and repeatability of the opening action. The product limiting frame 13 is crucial for product opening and serves as the mounting point for the gripping component 14. The gripping component 14 engages with the product components for limiting, and the first drive component 11 pulls the product limiting frame 13 to reciprocate, thus achieving full automation of the product opening, limiting, and precise delivery process.

[0022] Furthermore, in this embodiment, the box opening assembly 1 further includes a rotating pressure rod assembly 15, which consists of a rotating frame 150, a product pressure rod 151, and a fixing rod 152. The fixing rod 152 is fixedly fitted on the first frame 10, and the rotating frame 150 is rotatably mounted on the product limiting frame 13. The product pressure rod 151 and the fixing rod 152 are respectively disposed at both ends of the rotating frame 150. Therefore, the rotating frame 150 serves as the rotating main body of the rotating pressure rod assembly 15. The rotating frame 150 is mounted on the first frame 10 via a connection such as bearings or hinges. The product pressure rod 151 is located at one end of the rotating frame 150. It is driven to one side of the product component by the forward movement of the rotating frame 150. When the rotating frame 150 moves backward, the product pressure rod 151 applies pressure to the product component to ensure that the product component remains stable during processing, assembly, or transportation. The fixed rod 152 provides a stable support point for the rotating frame 150. It serves as the fulcrum for the rotation of the rotating frame 150, ensuring that the rotating frame 150 can rotate stably around it.

[0023] Furthermore, in this embodiment, the first driving component 11 includes a drive motor 110, a rocker arm 111, and a rocker arm 112. The drive motor 110 is connected to one end of the rocker arm 111, and the drive motor 110 drives the rocker arm 111 to rotate. The other end of the rocker arm 111 is connected to the rocker arm 112, and the rocker arm 112 is connected to the product limiting frame 13. Thus, the drive motor 110 acts as a power source, providing rotational power for the entire movement. The rocker arm 111 is a key component for changing the direction of motion, converting the rotational motion of the drive motor 110 into the linear motion of the rocker arm 112. The rocker arm 112 is an actuating component, transmitting the motion of the rocker arm 111 to the product limiting frame 13, pushing the product limiting frame 13 to perform reciprocating linear motion.

[0024] Furthermore, in this embodiment, the limiting conveyor belt 2 includes a second frame 20, a second drive component 21, a conveyor belt component 22, a plurality of adjustable grippers 23, and a pressing box edge component 24. The second drive component 21, the conveyor belt component 22, and the pressing box edge component 24 are disposed on the second frame 20. The second drive component 21 is used to drive the conveyor belt component 22. The plurality of adjustable grippers 23 are respectively installed on the conveyor belt component 22. The adjustable grippers 23 are used to limit the product element of the opened box, and the pressing box edge component 24 is used to limit the rocker wings on the product element of the opened box. Therefore, the second frame 20 provides a foundation for supporting and mounting the second drive component 21, the conveyor belt component 22, and the pressing box edge component 24. The second drive component 21 serves as a power source, driving the conveyor belt component 22 to move. The conveyor belt component 22 provides support and fixation for several adjustable grippers 23. The adjustable grippers 23 engage with the two sides of the product element to limit and fix the product element after opening the box. The pressing box edge component 24 limits the vertical movement of the product element after opening the box.

[0025] Furthermore, in this embodiment, the gripping component 14 is a vacuum suction cup, which adsorbs and engages with the side of the product component. Thus, the vacuum suction cup is a key component for gripping the product component, using negative pressure to firmly adhere to one side of the product component. Simultaneously, the vacuum suction cup avoids hard contact, making it suitable for gripping products with sensitive surface coatings without damaging the surface of the product component. It also offers high adaptability, accommodating product components of different sizes.

[0026] Optionally, in this embodiment, the gripping component 14 is a pressure-sensitive adhesive, which adsorbs and engages with the side of the product element. Therefore, if the side of the product element is made of rough cardboard, fabric, or porous material, the pressure-sensitive adhesive can form a mechanical lock by penetrating tiny pores, providing a more stable gripping force than a vacuum suction cup. Compared to a vacuum suction cup, pressure-sensitive adhesive eliminates the need for vacuum generators, piping, and other accessories, reducing equipment complexity and failure rate, and offering higher stability and lower design costs.

[0027] Example 2

[0028] Furthermore, in this embodiment, the first driving component 11 is a fluid transmission actuator. The movable end of the fluid transmission actuator is connected and cooperates with the product limiting frame 13. The fluid transmission actuator is used to drive the product limiting frame 13 to reciprocate. Therefore, the first driving component 11 is a fluid transmission actuator, which has the function of driving and reciprocating motion, eliminating the need for a linkage mechanism. Moreover, the fluid transmission actuator has advantages such as motion flexibility, control precision, and smooth box opening.

[0029] The working principle of this utility model is as follows:

[0030] Several unopened products move toward the opening assembly 1 under the push of an external feeder. The first drive component 11 drives the product limiting frame 13 to move back and forth. The gripping component 14 engages with the largest surface area of ​​the unopened product element and pulls the gripping side to move. The other side of the product element remains fixed on the feeder. Finally, the product element is transformed into an opened product element. The product limiting frame 13 continues to move so that the opened product element is completely detached from the feeder. The opened product element is simultaneously limited and engaged with the adjustable gripper 23 on the limiting conveyor belt 2. The second drive component 21 drives the conveyor belt component 22 to rotate, and the conveyor belt component 22 carries the opened product element into the next station.
