[0050] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0051] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0052] See Figures 1-6 This embodiment provides a flip-top closing device, which includes a feeding mechanism 100, a clamping mechanism 200, and a flip-top closing mechanism 300. The flip-top closing mechanism 300 includes a driver, a closing assembly 320, and a flipping assembly 330. The driver is connected to the closing assembly 320 and is used to drive the moving part 321 of the closing assembly 320 to move. The flipping assembly 330 includes a flipping base 331, a swing rod 332, and a guide structure. The clamping mechanism 200 is mounted on the flipping base 330, and the swing rod 332... One end is pivotally connected to the moving part 321 and fixedly connected to the flipping seat 331; the other end of the swing rod 332 is equipped with a cam follower 333, and the guide structure cooperates with the cam follower 333; when the moving part 321 is in the loading position, the clamping mechanism 200 is in the material picking posture, and can receive and clamp the cover 700 supplied by the feeding mechanism 100; when the moving part 321 is in the closed position, the clamping mechanism 200 is in the closed posture, and can close the clamped cover 700 onto the box body 800.
[0053] When material needs to be picked up, the drive unit can be controlled to move the movable part 321 of the cover assembly 320 toward the loading position. During the movement, the movable part 321 will drive the swing rod 332 to move synchronously with one end connected to it. At the same time, the cam follower 333 installed at the other end of the swing rod 332 will move along the guide structure. Under the guidance of the guide structure, the swing rod 332 will swing, and the flipping seat 331 will flip toward the material picking posture under the drive of the swing rod 332. When the movable part 321 moves to the loading position, the clamping mechanism 200 will simultaneously flip to the material picking posture or has already flipped to the material picking posture. At this time, the clamping mechanism 200 can receive and clamp the cover 700 supplied by the feeding mechanism 100.
[0054] When the lid 700 held by the clamping mechanism 200 needs to be closed onto the box 800, the driver can be controlled to drive the moving part 321 of the lid closing assembly 320 to move in the opposite direction toward the lid closing position. During this process, the swing rod 332 will swing in the opposite direction, and the flipping seat 331 will flip toward the lid closing posture under the action of the swing rod 332. When the moving part 321 moves to the lid closing position, the clamping mechanism 200 will simultaneously flip to the lid closing posture or has already flipped to the lid closing posture. At this time, the clamping mechanism 200 can close the clamped lid 700 onto the box 800, completing the lid closing.
[0055] Therefore, the flipping and closing device provided in this embodiment can realize the automatic flipping and closing of the cover 700 with a single driver, which helps to reduce costs, has a high cost performance, and has a compact structure that can reduce the space occupied. In addition, the flipping action and closing action of the cover 700 are performed simultaneously, which can improve production efficiency and achieve the goal of high production capacity.
[0056] The flip-top closing device provided in this embodiment is particularly suitable for loading and closing packaging boxes for various small-sized electronic products and electronic accessories.
[0057] Preferably, the swing arm 332 can be connected to the moving part 321 via a rotating shaft 335, and a bearing 336 can be provided between the rotating shaft 335 and the moving part 321.
[0058] Preferably, an elastic element can be connected between the swing rod 332 and the moving part 321. Under the elastic force of the elastic element, the swing rod 332 is not easy to shake, which helps to improve the structural stability and keep the clamping mechanism 200 stable. In turn, it can improve the clamping reliability of the cover 700 and the positional accuracy when closing the cover, so that the cover 700 can be smoothly fastened to the box 800.
[0059] The guide groove 410 can be used as the aforementioned guide structure. In the specific structure of the guide groove 410, two straight grooves 411 and two arc-shaped grooves 412 can be provided. The arc-shaped grooves 412 are set between the two straight grooves 411. In this way, when the moving part 321 moves between the loading position and the closing position, the cam follower 333 will first move along one of the straight grooves 411, then move along the two arc-shaped grooves 412 in sequence, and finally move along the other straight groove 411. During the movement of the cam follower 333 along the straight groove 411, the swing rod 332 will not swing, and the clamping mechanism 200 will maintain its current posture. During the movement of the cam follower 333 along the arc-shaped groove 412, the swing rod 332 will swing to adapt to the position change of the cam follower 333 relative to the flipping seat 331. Thus, the flipping seat 331 can flip, and the clamping mechanism 200 can switch between the material picking posture and the closing posture. It should be noted that a straight groove 411 is provided on both sides of the arc-shaped groove 412, which enables the clamping mechanism 200 to switch to the corresponding posture before the moving part 321 moves into place. This not only ensures the closing effect but also facilitates structural design and avoids structural interference between the clamping mechanism 200 and the feeding mechanism 100, the cover 700, and the box 800.
[0060] Furthermore, the straight groove 411 and the arc groove 412 can be smoothly transitioned to improve the smoothness of the movement of the cam follower 333. On this basis, the two arc grooves 412 can be connected together, and the convex sides of the two arc grooves 412 can be opposite each other. The elastic force applied to the swing rod 332 by the elastic element is set to face the concave side of the arc groove 412. In this way, the cam follower 333 can always move along the smooth surface of the arc groove 412, ensuring the smoothness of the movement of the cam follower 333 and reducing the probability of jamming.
[0061] Specifically, a tension spring 334 can be used as the aforementioned elastic element. The tension spring 334 can achieve the aforementioned functions of the elastic element, and the effect is better and the cost is lower.
[0062] Preferably, the two arc-shaped grooves 412 are symmetrically arranged, and the arc angles corresponding to the arc-shaped grooves 412 are all set to 90°. Based on this, the cover 700 in the feeding mechanism 100 can be stacked vertically, which is conducive to the cover 700 sliding smoothly to the clamping mechanism 200; and the box 800 is laid flat with the opening facing upward, so that the cover 700 can be smoothly closed onto the box 800.
[0063] The guide groove 410 can be formed on the fixed plate 400. The fixed plate 400 can be made of 45# carbon steel, which can improve the hardness and wear resistance of the guide groove 410, extending its service life and guiding accuracy. Preferably, the surface of the fixed plate 400 can be high-frequency quenched to further improve the hardness and wear resistance of the guide groove 410.
[0064] A fixed base 500 can also be provided to fix the fixed plate 400 to the fixed base 500. A reinforcing rib 510 can be provided between the fixed plate 400 and the fixed base 500.
[0065] The aforementioned feeding mechanism 100, driver, and cover assembly 320 can all be mounted on the fixing plate 400.
[0066] In the specific structure of the feeding mechanism 100, a hopper 110 and a clamping assembly can be provided. The cover 700 can be stacked into the hopper 110 from bottom to top. The bottom opening of the hopper 110 is provided so that the cover 700 in the hopper 110 can fall from the bottom opening. The clamping assembly can clamp the cover 700 at the bottom of the hopper 110. Thus, under the action of the clamping assembly, the cover 700 can remain in the hopper 110. When the moving part 321 moves to the loading position, the clamping component can be controlled to release the cover 700, so that the cover 700 in the hopper 110 slides down as a whole. Thus, the cover 700 at the bottom can be received and clamped by the clamping mechanism 200 to realize the loading action. After the loading is completed, the cover 700 that was originally at the bottom will slide down to the position corresponding to the clamping component, which is the bottom cover 700 in the hopper 110 in this state. At this time, the clamping component can be controlled to clamp the cover 700. Thus, after the moving part 321 leaves the loading position, the cover 700 in the hopper 110 can still remain in the hopper 110.
[0067] In the specific structure of the clamping assembly, at least two opposing first cylinders 120 can be provided, and a first clearance groove 111 is opened at the lower end of the hopper 110, which is respectively opposite to each of the first cylinders 120, so that the telescopic end of the first cylinder 120 can press the cover 700 inside the hopper 110 through the first clearance groove 111.
[0068] In the specific structure of the clamping mechanism 200, at least two clamping plates can be provided opposite to each other. A second clearance groove 112 opposite to each clamping plate can be opened at the lower end of the hopper 110, so that the clamping plates can clamp the cover 700 inside the hopper 110 through the second clearance groove 112.
[0069] The motor 310 can be used as the aforementioned driver. In the specific structure of the lid-closing assembly 320, a lead screw guide module 322 can be provided. The motor 310 is connected through the lead screw guide module 322 to drive the lead screw in the lead screw guide module 322 to rotate. The nut in the lead screw guide module 322 is fixedly connected to the moving part 321. The rotation of the lead screw drives the nut to move along the lead screw, which in turn drives the moving part 321 to move, thus driving the moving part 321. This configuration allows the moving speed and position of the clamping mechanism 200 to be controllable, and ensures that the lid-closing speed and force do not exceed limits. The motor 310 is a servo motor.
[0070] In the specific structure of the cover assembly 320, a precision guide rail 323 can also be provided. The moving part 321 can be matched with the precision guide rail 323 to further improve the smoothness and accuracy of the movement of the moving part 321.
[0071] In the specific structure of the clamping mechanism 200, a second cylinder 210 and a gripper 220 can be provided. The second cylinder 210 is connected to the gripper 220 so that the second cylinder 210 drives the gripper 220 to clamp and release the cover 700. The part of the gripper 220 that contacts the cover 700 is a clamping plate.
[0072] The gripper 220 of the clamping mechanism 200 can be set as a rubber-coated gripper to increase the gripping friction of the gripper 220 on the cover 700 and improve the clamping reliability of the cover 700.
[0073] The second cylinder 210 clamps the cover 700 in the center for secondary positioning.
[0074] The flip-top closing device provided in this embodiment uses a motor 310 as the basic power source, combined with components such as a cam follower 333, a tension spring 334, a cylinder, a guide groove 410, and a hopper 110. It can precisely control the position of the clamping mechanism 200 and the closing force; and can achieve rapid flip-top closing with stable operation. Except for the motor 310, all other power sources in the overall structure are pneumatic components, resulting in simple control logic and convenient operation. Furthermore, the flip-top closing device provided in this embodiment has a simple overall structure, few parts, easy maintenance, and is easy to operate, making it highly adaptable.
[0075] The specific operation flow of the flip-top closing device provided in this embodiment is as follows: ① The lid body 700 stack is manually placed into the hopper 110, such as... Figure 7 As shown, →② the clamping mechanism 200 swings to the material picking position, as... Figure 8 As shown →③ The first cylinder 120 is released, and the second cylinder 210 is clamped, as...

Figure 12 As shown →⑦ Clamping mechanism 200 flips back, as Figure 13 As shown.
[0076] This embodiment also provides a packaging device, which includes the above-described flipping and closing device.

It is conducive to reducing costs, has a high cost performance, and has a compact structure that can reduce the space occupied. In addition, the flipping action of the lid 700 and the closing action are carried out simultaneously, which can improve production efficiency and achieve the goal of high production capacity.
[0078] The packaging equipment may also include a platform 600 for supporting the box 800.
