[0035] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0036] Laser engraving is a process that uses a high-energy laser beam to carve intricate patterns or text onto the surface of a material. Currently, this technology is widely used on products such as electronic atomizing devices to permanently mark brand logos, anti-counterfeiting codes, and personalized designs. During laser engraving, the product typically needs to be rotated and fixed at a specific angle so that the laser head can engrave one product at a time according to the program. However, in existing technologies, the product position still needs to be manually calibrated during laser engraving, which not only leads to low production efficiency but also makes it difficult to ensure precise control of the product position.

[0037] Please see Figures 1 to 3 , Figure 1 This is a top view of the rotating mechanism in some embodiments of this application. Figure 2 yes Figure 1 A front view of the rotating mechanism in the embodiment. Figure 3 yes Figure 1 A schematic diagram of the carrier assembly in the rotating mechanism of the embodiment.

[0038] This application provides a rotating mechanism, including a stage 10, a carrier assembly 20, a calibration assembly 30, and a drive assembly 40.

[0039] The carrier assembly 20 is rotatably mounted on the stage 10 and can carry multiple products, such as electronic atomizing devices requiring laser engraving. Furthermore, the carrier assembly 20 may include a mounting base 21 and multiple positioning structures 211 for positioning the products. The positioning structures 211 are evenly distributed on the mounting base 21 to ensure that each product remains stably in a predetermined position during rotation. The mounting base 21 is mounted on the stage 10 via rotating connectors such as bearings to achieve smooth rotation.

[0040] A calibration assembly 30 is disposed on the platform 10. The calibration assembly 30 includes a first calibration member 31 and a second calibration member 32, which are respectively disposed on both sides of the rotation axis of the carrier assembly 20 to limit the rotation angle of the carrier assembly 20. A drive assembly 40 is used to drive the carrier assembly 20 to rotate and keep the carrier assembly 20 in contact with the first calibration member 31 or the second calibration member 32.

[0041] In this application, by setting up a carrier assembly 20, multiple products placed on it are driven to rotate synchronously to different states relative to the platform 10, thereby reducing manual operation and simplifying the operation process; at the same time, by using the first calibration member 31 and the second calibration member 32 set on both sides of the rotation axis of the carrier assembly 20 to abut against the carrier assembly 20 respectively, the rotation angle is precisely controlled, effectively improving the processing accuracy.

[0042] Please see Figure 4 and Figure 5 , Figure 4 yes Figure 1 A schematic diagram of the carrier assembly abutting against the first calibration member in the rotating mechanism of the embodiment. Figure 5 yes Figure 1 The diagram illustrates the contact between the carrier assembly 20 and the second calibration member in the rotating mechanism of this embodiment. In some implementation scenarios, the carrier assembly 20 is in laser engraving mode when it contacts the first calibration member 31. At this time, each product is tilted on the platform 10, with the side of the product to be engraved facing the laser head. The precise positioning of the carrier assembly 20 in laser engraving mode by the first calibration member 31 ensures that each product receives a consistent engraving effect, avoiding engraving quality problems caused by positional deviations. The carrier assembly 20 is in material handling mode when it contacts the second calibration member 32. At this time, the product to be engraved can be placed vertically on the carrier assembly 20, or the engraved product can be removed from the carrier assembly 20. Because the product remains vertical in material handling mode, the operator can safely perform product loading and unloading operations.

[0043] Please continue reading. Figure 4 and Figure 5In some embodiments, the side of the first calibration member 31 that abuts against the carrier assembly 20 is the first contact surface 311, and the side of the second calibration member 32 that abuts against the carrier assembly 20 is the second contact surface 321. The first contact surface 311 and the second contact surface 321 are flat surfaces. The contact surfaces of the carrier assembly 20 with the first contact surface 311 and the second contact surface 321 are also flat surfaces to ensure a large contact area when the carrier assembly 20 abuts against the first calibration member 31 and the second calibration member 32, thus ensuring contact stability. The first calibration member 31 and the second calibration member 32 of the calibration assembly 30 can also be designed with shapes that match the edges of the carrier assembly 20, such as protrusions or grooves, so that they can precisely abut against the carrier assembly 20 when it rotates to a specific position, thereby accurately controlling the rotation angle of the carrier assembly 20. This design helps improve the positioning accuracy and repeatability of the rotating mechanism.

[0044] Please see Figure 2 In some embodiments, the drive assembly 40 includes an elastic element 41 and a pressing element 42. The elastic element 41 is connected between the carrier assembly 20 and the platform 10. The elastic element 41 is used to drive the carrier assembly 20 to rotate toward the first calibration member 31 and keep the carrier assembly 20 in contact with the first calibration member 31. The elastic element 41 includes, but is not limited to, a tension spring, a torsion spring, or an elastic rope. Taking a tension spring as an example, the tension spring is disposed on the side of the carrier assembly 20 facing the first calibration member 31. The two ends of the tension spring are respectively connected to the carrier assembly 20 and the platform 10. The tension spring is always kept in a stretched state so that the carrier assembly 20 always has a tendency to rotate toward the first calibration member 31, thereby enabling the carrier assembly 20 to rotate toward the first calibration member 31 and keep in contact with the first calibration member 31 under the action of the tension spring. There may be multiple tension springs, such as two or three, etc., which are not specifically limited here. Multiple tension springs can be spaced apart along the length of the vehicle assembly 20 to improve the stability of the vehicle assembly 20 against the first calibration member 31 and ensure that the vehicle assembly 20 is subjected to uniform force.

[0045] The pressing member 42 is movably mounted on the platform 10, and is capable of abutting against the carrier assembly 20 and causing the carrier assembly 20 to rotate towards the second calibration member 32 against the force of the elastic member 41. Exemplarily, the carrier assembly 20 includes a rotating arm 22 fixedly connected to the mounting base 21, and the pressing member 42 movably abuts against the side of the rotating arm 22 away from the second calibration member 32. Figure 2As shown, in some implementation scenarios, the pressing member 42 moves vertically, and the rotating arm 22 is positioned below the pressing member 42. During downward movement, the pressing member 42 abuts against the rotating arm 22 and drives the rotating arm 22 to rotate. At this time, the elastic member 41 further deforms to cooperate with the rotation of the carrier assembly 20. When the rotating arm 22 rotates to abut against the second calibration member 32, the pressing member 42 stops moving, keeping the carrier assembly 20 in the material handling state. During upward movement, the pressing member 42 can separate from the rotating arm 22. At this time, the elastic member 41 resets and drives the carrier assembly 20 to rotate towards the first calibration member 31 until it abuts against the first calibration member 31, thus keeping the carrier assembly 20 in the laser engraving state. In some implementation scenarios, the pressing member 42 can also move in other directions, as long as it can move to abut against the rotating arm 22 and drive the rotating arm 22 to rotate until it abuts against the second calibration member 32.

[0046] The drive assembly 40 also includes a drive member 45, which is connected to the pressing member 42 to drive the pressing member 42 to move. The drive member 45 can be a linear drive mechanism, including but not limited to cylinders, hydraulic cylinders, lead screws, etc. In this embodiment, the rotating arm 22 can be used as a lever arm. Based on the lever principle, when the pressing member 42 applies force to the carrier assembly 20, the drive of the carrier assembly 20 can be achieved with less effort, that is, the power requirement of the drive member 45 is effectively reduced, so that the rotating arm 22 can be smoothly rotated to the position of abutting against the second calibration member 32.

[0047] Please see Figure 1 and Figure 2 Furthermore, the carrier assembly 20, calibration assembly 30, and elastic element 41 are provided in multiple sets, each corresponding to the other. This one-to-one correspondence means that each set of corresponding carrier assemblies 20, calibration assemblies 30, and elastic elements 41 cooperates with each other. Each set of elastic elements 41 may include multiple elastic components, which are connected to the platform 10 and the corresponding carrier assembly 20. Each set of calibration assemblies 30 may also include multiple first calibration components 31 and multiple second calibration components 32, which respectively movably abut against the corresponding carrier assembly 20. Each carrier assembly 20 is distributed circumferentially along the pressing member 42, and the platform 10 and the pressing member 42 are configured to rotate relative to each other so that each carrier assembly 20 can movably abut against the pressing member 42.

[0048] Specifically, the rotating mechanism also includes a support base 50. In some embodiments, the platform 10 may be designed to be fixedly connected to the support base 50, the driving member 45 may be rotatably connected to the support base 50, and the pressing member 42 may be connected to the moving end of the driving member 45. In some embodiments, the driving member 45 is fixedly connected to the support base 50, the platform 10 is rotatably connected to the support base 50, and the pressing member 42 is connected to the moving end of the driving member 45. In some embodiments, the pressing member 42 is connected to the moving end of the driving member, and both the platform 10 and the driving member are rotatably connected to the support base 50.

[0049] In this way, a pressing component 42 can apply force to multiple sets of carrier components 20 respectively, and with the precise cooperation between each set of carrier components 20 and the corresponding calibration component 30 and elastic component 41, it can be ensured that each set of carrier components 20 can be stably maintained in the material loading and unloading state and the laser engraving state respectively.

[0050] In the aforementioned embodiment where the driving component 45 is fixedly connected to the support base 50 and the platform 10 is rotatably connected to the support base 50, the workstation for picking up and placing products and the workstation for laser engraving can be set up separately. The picking and placing workstation corresponds to the position of the pressing component 42. During picking and placing, the pressing component 42 drives the current carrier assembly 20 to rotate until it abuts against the second calibration component 32. At this time, the operator can easily place the product to be engraved vertically on the current carrier assembly 20, or remove the engraved product from the current carrier assembly 20. After picking and placing, the driving platform 10 drives the current carrier assembly 20 to rotate to the laser engraving workstation, and causes the next carrier assembly 20 to rotate to correspond to the position of the pressing component 42, for the next round of work. This not only improves the efficiency and accuracy of laser engraving on the electronic atomization device, but also simplifies the operation process and improves overall production efficiency.

[0051] Please see Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the carrier assembly 20 abutting against the first calibration member 31 in another embodiment of the rotating mechanism. Figure 7 yes Figure 6This is a schematic diagram showing the contact between the carrier assembly 20 and the second calibration member 32 in the rotating mechanism of the embodiment. In some embodiments, the driving assembly 40 includes a pressing member 44, which is movably mounted on the platform 10. The pressing member 44 includes a first abutting portion 441 and a second abutting portion 442 spaced apart along the moving direction of the pressing member 44. During the movement of the pressing member 44, the first abutting portion 441 abuts against the carrier assembly 20 and drives the carrier assembly 20 to rotate toward the first calibration member 31 until it abuts against the first calibration member 31; or the second abutting portion 442 abuts against the carrier assembly 20 and drives the carrier assembly 20 to rotate toward the second calibration member 32 until it abuts against the second calibration member 32. It is understood that in this embodiment, the station for picking up and placing materials and the station for laser engraving are located in the same position.

[0052] like Figure 6 and Figure 7 As shown, in some implementation scenarios, the pressing member 44 moves vertically, and the rotating arm 22 is positioned between the first abutment portion 441 and the second abutment portion 442 of the pressing member 44. During the upward movement of the pressing member 44, the first abutment portion 441 abuts against the rotating arm 22 and drives the rotating arm 22 to rotate. When the rotating arm 22 rotates to abut against the first calibration member 31, the pressing member 44 stops moving in its original direction, keeping the carrier assembly 20 in the laser-engraved state. During the downward movement of the pressing member 44, the second abutment portion 442 abuts against the rotating arm 22 and drives the rotating arm 22 to rotate. When the rotating arm 22 rotates to abut against the second calibration member 32, the pressing member 44 stops moving in its original direction, keeping the carrier assembly 20 in the loading / unloading state. In some implementation scenarios, the pressing member 44 can also move in a non-vertical direction to rotate the carrier assembly 20 to abut against the first calibration member 31 or the second calibration member 32.

[0053] Furthermore, please combine Figure 1 and Figure 2 Multiple sets of carrier assemblies 20 and calibration assemblies 30 are provided and correspond one-to-one, with each carrier assembly 20 distributed circumferentially along the pressure member 44. The platform 10 and the pressure member 44 are configured to rotate relative to each other so that each carrier assembly 20 can movably abut against the pressure member 44. Specifically, in some implementation scenarios, the platform 10 is rotatably connected to the support base 50, the drive member 45 is fixedly mounted on the support base 50, the pressure member 44 is connected to the moving end of the drive member 45, and the carrier assembly 20 includes a rotating arm 22 fixedly connected to the mounting base 21. The first abutting portion 441 and the second abutting portion 442 of the pressure member 44 movably abut against opposite sides of the rotating arm 22.

[0054] Please see Figure 6 and Figure 7Furthermore, the drive assembly 40 also includes a snap-fit ​​structure 43, which is disposed between the platform 10 and the carrier assembly 20 to snap the carrier assembly 20 onto the platform 10 and maintain it in contact with the first calibration member 31. The snap-fit ​​structure 43 includes a snap fastener 432 and a slot 431. The snap fastener 432 is disposed on one of the carrier assembly 20 and the platform 10, and the slot 431 is disposed on the other. Given that the carrier assembly 20 has multiple sets of snap-fit ​​structures, multiple sets of snap-fit ​​structures 43 are also provided, each corresponding to one of the carrier assemblies 20. By providing the snap-fit ​​structure 43, the carrier assembly 20 can remain in contact with the first calibration member 31 even without the action of the pressing member 44.

[0055] In this embodiment, the material handling station and the laser engraving station can be set up separately. When the carrier assembly 20 rotates to the position corresponding to the top pressure member 44, the top pressure member 44 acts on the carrier assembly 20 and keeps it in contact with the second calibration member 32. After the material handling is completed, the top pressure member 44 acts on the carrier assembly 20 again, so that the carrier assembly 20 abuts with the first calibration and the latching structure 43 latches 432. Then, the platform 10 can drive the current carrier assembly 20 to rotate to the laser engraving station, and the next carrier assembly 20 can rotate to the current station to handle material handling, thereby improving production efficiency.

[0056] In some embodiments, the lengths of the first calibration member 31 and / or the second calibration member 32 can be adjusted to adjust the angle of rotation of the carrier assembly 20 relative to the platform 10.

[0057] The lengths of the first calibration component 31 and / or the second calibration component 32 can be adjusted manually. Manual adjustment methods include, but are not limited to, using threads or pins. For example, the first calibration component 31 and the second calibration component 32 can be designed as threaded rods, allowing the user to adjust their extension length by rotating the threaded rods. Alternatively, the lengths of the first calibration component 31 and / or the second calibration component 32 can also be adjusted automatically, such as using an electric telescopic rod. This method enables more precise and rapid adjustment, improving the automation level and work efficiency of the equipment.

[0058] In practical applications, the angle of rotation of the carrier component 20 relative to the platform 10 can be adjusted according to specific needs to achieve the best production effect.

[0059] Optionally, the rotation angle range of the carrier assembly 20 is 0–60°, 0–45°, or 0–30°. It is understood that the rotation angle range of the carrier assembly 20 is closely related to the movement range of the pressing member 42 or the pressing member 44 in the drive assembly 40. By limiting the rotation angle of the carrier assembly 20 to a suitable range, production requirements are met while ensuring that the rotation angle range of the carrier assembly 20 matches the movement stroke of the pressing member 42 or the pressing member 44 in the drive assembly 40.
