[0040] To make the technical solution and beneficial effects of this application more apparent and understandable, a detailed description is provided below by listing specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application pertains.

[0041] This application provides a lid-opening device for opening or closing a target box 400. The target box 400 has two opposing first lids 410. The lid-opening device may include a first lid-opening mechanism 100. In this embodiment, as shown... Figure 1 As shown, the lid-opening device is integrated with the roller conveyor line, with the device fixedly mounted on both sides of the conveyor line, further improving the production efficiency of carton lid opening on the assembly line. This embodiment is merely exemplary and is not limited thereto. Alternatively, the lid-opening device can be directly fixed to a frame for lid opening operations.

[0042] The target box 400 of this application has at least one first opening mechanism 100 on one side of each first cover 410. Having two or more first opening mechanisms 100 on each side of the first cover 410, compared to having only one first opening mechanism 100 on one side of each first cover 410, can further improve the stability of opening the cover. The target box 400 has two first covers 410, such as... Figure 1 As shown, in this embodiment, two first opening mechanisms 100 are provided at each first cover 410 of the target box 400. Each first opening mechanism 100 may include: a first driving component 110, a swing component 120, a first suction cup 130, and an arc-shaped track 140. The first driving component 110 includes a cylinder, a linear motor, etc. In this embodiment, the first driving component 110 uses a pen-shaped cylinder, one end of which is hinged or rotatably connected to the frame to provide driving force for the first opening mechanism 100. The output end of the first driving component 110 is connected to the swing component 120. The execution end of the swing component 120 is connected to the first suction cup 130, which is made of a material with good flexibility and sealing properties, such as silicone, and is connected to a negative pressure system through a pipeline. The swing component 120 transmits the driving force of the first driving component 110 to the first suction cup 130. The arc-shaped track 140 is connected to the swing component 120 in a guiding fit to limit the movement trajectory of the swing component 120. The arc-shaped guide rail 140 is precision machined from high-hardness material, and its track surface is a circular arc with a constant radius.

[0043] In this embodiment, when opening or closing the first cover 410, the first driving component 110 drives the swing component 120 to move along the arc-shaped guide rail 140, thereby causing the first suction cup 130 to move. Since the center of the arc-shaped guide rail 140 coincides with the opening and closing axis of the first cover 410, the movement trajectory of the swing component 120 on the arc-shaped guide rail 140 corresponds to the movement trajectory of the first cover 410 during the opening or closing process. Therefore, the movement trajectory of the first suction cup 130 driven by the swing component 120 is adapted to the movement trajectory of the first cover 410, thereby achieving a more stable opening or closing of the first cover 410.

[0044] This application sets the center of the arc-shaped guide rail 140 to coincide with the opening and closing axis of the first cover 410, so that the motion trajectory of the first suction cup 130 driven by the swing assembly 120 is highly matched with the opening and closing trajectory of the first cover 410, which greatly improves the stability and accuracy of the opening and closing action. The output end of the drive assembly 110 of the opening device proposed in this application is directly converted into motion along a predetermined arc trajectory through the swing assembly 120. The power transmission path is short and there are fewer intermediate links, reducing the nodes that may fail (compared with complex opening devices with multiple hinge points, transmission rods, and connecting rods). This not only simplifies the structure but also improves the response speed and reliability of the action.

[0045] In some specific embodiments, the arc-shaped guide rail 140 of the first opening mechanism 100 is provided with a guide portion 141, and the swing assembly 120 is provided with a mating portion 121 adapted to the guide portion 141. The swing assembly 120 includes a swing arm or rocker arm, which transmits the power of the first drive assembly 110 to the first suction cup 130. The guide portion 141 includes a groove, and the mating portion 121 includes a rolling element 122. In this embodiment, the rolling element 122 is a roller. The inner ring bearing of the roller is fixedly connected to the mating portion 121 of the swing assembly 120 via a shaft. A wheel body is provided outside the bearing, and the outer diameter surface shape of the wheel body is adapted to the cross-sectional shape of the groove on the guide rail, thereby forming a tight contact with the groove of the guide rail and providing precise guidance. The cross-sectional shape of the groove may include an arc surface, a square, or a V-shape, etc. The rolling element 122 is connected to the first drive assembly 110 via a slider 123. The first drive assembly 110 drives the swing assembly 120 to move the slider 123 and the rolling element 122 along the groove, thereby causing the first suction cup 130 to open or close the first cover 410. The swing angle of the first suction cup 130 in the vertical plane is -5° to 95°, which is suitable for opening the first cover 410 of the target box 400 to an obtuse angle, facilitating the subsequent opening of the second cover (such as...). Figure 7 (As shown).

[0046] In some embodiments, the engagement of the rolling element 122 with the groove can include the following three scenarios: (1) A first groove 142 is provided on the inner wall of the arc-shaped guide rail 140 (i.e., the side near the center of the arc-shaped guide rail), and at least one rolling element 122 rolls into the first groove 142. (2) A second groove 143 is provided on the outer wall of the arc-shaped guide rail 140 (i.e., the side away from the center of the arc-shaped guide rail), and at least one rolling element 122 rolls into the second groove 143. (3) A first groove 142 is provided on the inner wall of the arc-shaped guide rail 140, and a second groove 143 is provided on the outer wall of the arc-shaped guide rail 140, and at least one rolling element 122 rolls into the first groove 142, and at least another rolling element 122 rolls into the second groove 143. Through various configurations of the inner groove, outer groove, or both inner and outer grooves of the arc-shaped guide rail 140, different spatial layouts can be adapted, and multiple designs are more stable than a single design.

[0047] Furthermore, the engagement between the rolling element 122 and the groove is not limited to the simple rolling engagement in this embodiment. In other embodiments, the rolling element 122 can be embedded inside the groove, and the rolling element 122 is wrapped in the groove to perform rolling motion. The guiding movement of the rolling element 122 within the groove in this application can effectively limit the movement trajectory of the swing assembly 120, avoiding shaking during the opening process, thereby ensuring a smoother and more reliable opening action of the first suction cup 130. At the same time, the rolling engagement reduces sliding friction, lowers wear, and extends the service life of the device.

[0048] In some embodiments, such as Figure 5 As shown, the first opening mechanism 100 of the opening device further includes a connecting block 150, which is connected to one end of the arc-shaped guide rail 140 to fix the arc-shaped guide rail 140. The structure and / or dimensions of the connecting block 150 can be configured with various different specifications (such as different mounting hole spacing, different extension lengths). By using connecting blocks 150 of different specifications, the position of the center of the arc-shaped guide rail 140 can be adjusted, thereby changing the installation position of the arc-shaped guide rail 140, making the opening device suitable for opening or closing target boxes 400 of different sizes.

[0049] In some embodiments, the lid-opening device further includes a clamping and positioning mechanism 200. The clamping and positioning mechanism 200 is used to fix the target box 400 before the lid-opening operation to prevent shaking during the opening of the target box 400, thereby ensuring the accuracy and consistency of the lid-opening action.

[0050] Specifically, the clamping and positioning mechanism 200 may include two, respectively symmetrically arranged on the target box 400 in the first direction (e.g., Figure 3The clamping and positioning mechanism 200 can be located on opposite sides in the x-direction. Each clamping and positioning mechanism 200 may include a linear drive assembly 210 and a clamping component 220. The linear drive assembly 210, as a power source, can be selected as a cylinder, electric push rod, or servo screw module, etc., and is fixed to the side of the production line or the frame. The clamping component 220 is installed at the output end of the linear drive assembly 210, and the part of it that contacts the target box 400 can be designed as a flat pressure plate, a V-block, or a flexible contact head to adapt to different box shapes.

[0051] During operation, the linear drive assembly 210 receives a control signal and drives its output end to perform linear motion, thereby causing the clamping components 220 to move synchronously in opposite directions or in opposite directions in the first direction. When it is necessary to fix the target box 400, the clamping components 220 on both sides simultaneously move closer to the target box 400 and firmly clamp the box from both sides. After the opening operation is completed, the linear drive assembly 210 drives the clamping components 220 to move in the opposite direction, releasing the clamping state of the target box 400. The clamping and positioning mechanism 200 can reliably clamp the target box 400 from both sides, ensuring that its position is fixed during the opening process, thereby greatly improving the accuracy of opening and the stability of operation.

[0052] In some embodiments, the clamping and positioning mechanism 200 further includes at least two positioning components 230. The positioning components 230 are respectively disposed on the target housing 400 in a second direction (e.g., ...). Figure 3 The two outer sidewalls (in the y-direction) are used to limit and block the target box 400 in the second direction, thereby cooperating with the active clamping component 220 in the first direction to form a bidirectional positioning system. By adding a positioning component 230 in the second direction, which works in conjunction with the original clamping component 220, complete constraint of the target box 400 in two directions in the horizontal plane is achieved, effectively preventing the box from deflecting in the horizontal plane during operation, and further improving the stability of the entire opening process.

[0053] In some embodiments, each clamping and positioning mechanism 200 integrates two positioning components 230. One end of each component is fixed to a clamping component 220 and extends outward in a direction parallel to the first direction and away from the clamping component 220. Each positioning component 230 may include a positioning plane 231 for abutting against the sidewall of the target box 400 in the second direction to achieve precise positioning, and a guide ramp 232 extending obliquely from the positioning plane 231 toward the side away from the center of the target box 400. The guide ramp 232 forms an obtuse angle with the positioning plane 231, such that when the clamping and positioning mechanism 200 moves toward the target box 400, the guide ramp 232 can first contact the box and use its inclined surface to guide the box to slide into and be corrected to the predetermined area between the two positioning planes 231, thereby achieving fast and accurate centering and positioning. The integrated positioning design of this application realizes automatic guidance and centering of the box through the guide inclined surface 232, which significantly improves the positioning efficiency, accuracy and reliability of the target box 400.

[0054] In some embodiments, such as Figure 7 As shown, the lid-opening device of this application can also be used to process target boxes 400 with multiple different lid structures. In addition to two opposing first lids 410 (outer lids), the target box 400 also includes second lids 420 (inner lids) adjacent to and opposing the two first lids 410. For opening or closing the second lids 420, the lid-opening device further includes at least two second lid-opening mechanisms 300. For example... Figure 5 As shown, each second opening mechanism 300 includes a second drive assembly 310 (such as a cylinder or motor) and a second suction cup 320. The output end of the second drive assembly 310 is a rotational motion, and its rotation axis coincides with the opening and closing axis of the second cover 420. The second drive assembly 310 and the second suction cup 320 are connected by a rotating arm 330. After the first opening mechanism 100 completes the opening of the first cover 410, the second drive assembly 310 drives the rotating arm 330 to rotate, thereby driving the second suction cup 320 to move, ultimately achieving a smooth opening of the second cover 420. The swing angle of the second suction cup 320 in the vertical plane is -5° to 105°, which is suitable for opening the second cover 420 of the target box 400 to an obtuse angle. When the second cover 420 is opened to an obtuse angle, it is convenient for the operator to retrieve the product from the target box. The lid opening device of this application achieves sequential, efficient, and automated opening of a box with multiple lid structures through a strategy of cooperating drive of the first drive component 110 and the second drive component 310.

[0055] In some embodiments, the clamping and positioning mechanism 200 includes a slide base 240, which is fixedly connected to the output end of the linear drive assembly 210. The clamping component 220 and the positioning component 230 are both fixedly connected to the slide base 240. The linear drive assembly 210 drives the slide base 240 to move, thereby driving the clamping component 220 and the positioning component 230 to move. Each clamping and positioning mechanism 200 of the lid-opening device is connected to at least one first lid-opening mechanism 100 and at least one second lid-opening mechanism 300. Specifically, in this embodiment, as... Figure 4 As shown, two first opening mechanisms 100 and two second opening mechanisms 300 are symmetrically fixedly arranged on a slide base 240 along a second direction. The two first opening mechanisms 100 are arranged adjacent to each other along the second direction and located between the two second opening mechanisms 300. The two first opening mechanisms 100 are fixedly connected to the slide base 240 via connecting blocks 150. Clamping components 220 and positioning components 230 are fixedly connected to both ends of the slide base 240.

[0056] When the linear drive assembly 210 moves, the two first opening mechanisms 100 and two second opening mechanisms 300 connected to the same slide base 240 move synchronously with the slide base 240. The two slide mechanisms 240 on each side drive the four first opening mechanisms 100 and four second opening mechanisms 300 on each side to move synchronously. After clamping the target box 400, the four first opening mechanisms 100 on each side simultaneously open the first cover 410 of the target box 400, and the four second opening mechanisms 300 simultaneously open the second cover 420 of the target box 400. This linkage design of the opening device allows multiple opening mechanisms to move synchronously and precisely with the clamping and positioning mechanism 200, eliminating the need to adjust each mechanism individually and significantly improving the accuracy and efficiency of positioning and opening.

[0057] When the opening device of this application needs to adapt to target boxes 400 of different widths, it is only necessary to adjust the initial positions of the two clamping and positioning mechanisms 200, and the clamping and positioning mechanisms 200 will move to the preset clamping position. During this process, the first opening mechanism 100 and the second opening mechanism 300, which are fixedly connected to the slide base 240 of the clamping and positioning mechanism 200, will move synchronously. There is no need to perform individual position calibration for each opening mechanism, which greatly improves the overall practicality of the opening device.

[0058] In some embodiments, the lid-opening device may further include a negative pressure assembly. The negative pressure assembly may include a vacuum pump, air lines, a distributor, and several solenoid valves, collectively forming a negative pressure supply system. This supply system serves as a central negative pressure source, connected to the distributor via a main air supply line, and connected to each of the first suction cups 130 and the second suction cups 320 via multiple branch air lines, forming a complete negative pressure adsorption network. When the control system issues an adsorption command, the solenoid valve in the corresponding suction cup line is opened, the vacuum pump starts, and the air in the adsorption circuit is quickly removed, thereby creating the required working negative pressure within the cavities of the first suction cup 130 and / or the second suction cup 320. When the lid needs to be released, the control system instructs the corresponding solenoid valve to cut off the negative pressure supply, restoring normal pressure inside the suction cup, releasing the adsorption force, and causing the suction cup to separate from the lid.

[0059] The specific working process of the lid-opening device in this application is as follows:

[0060] The target box 400 is transported to the working position of the opening device by an external conveyor line (such as a belt conveyor or roller conveyor), and the side of the target box 400 is clamped and positioned by the clamping and positioning mechanism 200. The negative pressure component is activated to provide negative pressure to the first suction cup 130. After receiving the control signal, the first drive component 110 starts to drive. Since the swing component 120 is connected to the output end of the first drive component 110, and the rolling element 122 on it is constrained in the groove of the arc-shaped guide rail 140, the swing component 120 moves along the arc-shaped guide rail under the drive of the first drive component 110. Thus, the first suction cup 130 drives the first cover 410 to open smoothly. When it is necessary to open the second cover 420, the second drive component 310 is activated. The second suction cup 320 generates negative pressure under the suction force provided by the negative pressure component. The output shaft of the second drive component 310 rotates, driving the rotating arm 330 and the second suction cup 320 at one end of the rotating arm 330 to work, thereby completing the opening of the second cover 420. The closing process is the reverse of the opening process. The second drive assembly 310 moves in the opposite direction, causing the second cover 420 to close. When the second cover 420 moves to the designated position, the negative pressure assembly cuts off the negative pressure supply to the second suction cup 320, and the second suction cup 320 releases the second cover 420. The first drive assembly 110 moves in the opposite direction, causing the first cover 410 to close. When the first cover 410 moves to the designated position, the negative pressure assembly cuts off the negative pressure supply to the first suction cup 130, and the first suction cup 130 releases the first cover 410.

[0061] The lid-opening device of this application has a simple structure. It achieves the opening or closing of the first lid through the organic combination of the first drive component 110, the swing component 120, and the arc-shaped guide rail 140. The short power transmission path reduces the probability of malfunction, simplifying the structure and improving the response speed and reliability of the action. The clamping and positioning mechanism 200 designed in this application clamps and positions the target box 400 at different positions on the same horizontal plane, significantly improving the clamping and positioning accuracy of the box. Simultaneously, the first lid-opening mechanism 100 and the second lid-opening mechanism 300 of this lid-opening device work together to open the lid, effectively avoiding problems such as jamming, collisions, and lid damage during the opening process, making it suitable for automated production lines.
