In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0029] The terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or structure referred to must have a particular orientation, be constructed and operated in a particular orientation.

[0030] Please refer to Figures 1-3 The cigarette laser drilling light path device provided by the present application comprises a light path switching assembly 10, a focusing assembly 20 and a laser galvanometer 30. External laser can enter the light path switching assembly 10, the propagation path of the laser is switched through the light path switching assembly 10, and then the focusing assembly 20 is selected to drill the product according to actual needs, or the laser galvanometer 30 is selected to drill the product.

[0031] Please refer to Figure 4 The light path switching assembly 10 comprises a shell 11 and a mirror 12. The shell 11 is provided with an entrance and two exits. The mirror 12 is arranged in the shell 11. Laser enters the shell 11 from the entrance and can irradiate the mirror 12 to reflect the laser to a certain exit.

[0032] The focusing assembly 20 is connected to an exit and comprises a focusing mirror and other components. After the laser beam is incident on the focusing mirror, the laser is focused on a fixed point through the focusing mirror to realize the function of single-point drilling. The position of the laser focus point is not easy to change, and the accuracy is high.

[0033] For example, the focusing assembly 20 can be used to drill the filter of a cigarette. The laser is focused on the filter of the cigarette, and a circle of air inlet holes is drilled on the filter of the cigarette by rotating the cigarette.

[0034] The laser galvanometer 30 is connected to another light outlet, which includes two scanning mirrors or the like. After the laser beam enters the two scanning mirrors, the reflection angle of the scanning mirrors can be controlled so that the two scanning mirrors can scan along the X and Y axes respectively, thereby realizing deflection of the laser beam and movement of the laser focal point according to requirements.

[0035] For example, the laser galvanometer 30 can be used to draw lines and patterns on a cigarette. The laser is focused on the surface of the cigarette, and the two scanning mirrors are used to scan along the X and Y axes respectively, so that the laser focal point moves along a preset track to form the required lines and patterns on the cigarette.

[0036] In specific implementations, the light path switching assembly 10 can switch the light path in various ways. For example, after the laser irradiates the mirror 12, the angle of the mirror 12 can be directly adjusted to change the reflection angle of the laser, so as to select a light outlet to which the laser is reflected.

[0037] Alternatively, the position of the mirror 12 can be adjusted so that the laser does not pass through the mirror 12 and is directly emitted from a certain light outlet, or the laser passes through the mirror 12 and is emitted from another light outlet.

[0038] In some embodiments, the light path switching assembly 10 further includes a driving member and a sliding seat 13. The mirror 12 is arranged on the sliding seat 13, and the driving member is used to drive the sliding seat 13 to move so that the mirror 12 moves into / out of the propagation path of the laser.

[0039] When the driving member drives the sliding seat 13 to move so that the mirror 12 moves out of the propagation path of the laser, the laser can be directly emitted from a certain light outlet. When the driving member drives the sliding seat 13 to move so that the mirror 12 moves into the propagation path of the laser, the mirror 12 changes the emission direction of the laser so that the laser is emitted from another light outlet.

[0040] For example, the first light outlet is connected to the focusing assembly 20, and the second light outlet is connected to the laser galvanometer 30. When the driving member drives the sliding seat 13 to move so that the mirror 12 moves out of the propagation path of the laser, the laser enters the focusing assembly 20 and is focused on a fixed point. When the driving member drives the sliding seat 13 to move so that the mirror 12 moves into the propagation path of the laser, the laser enters the laser galvanometer 30, so that the laser focal point moves along a required track.

[0041] During the light path switching process, manual driving or automatic driving can be used to realize movement of the sliding seat 13 and the mirror 12.

[0042] For example, please refer to Figure 1The driving member is selected as a pull rod 14, one end of the pull rod 14 is connected to the sliding seat 13, the other end of the pull rod 14 extends out of the shell 11, the shell 11 is provided with a buckle for fixing the pull rod 14. The pull rod 14 drives the sliding seat 13 to move, and then the position of the sliding seat 13 and the reflector 12 is changed, so that the reflector 12 is moved into / out of the propagation path of the laser.

[0043] In specific implementation, the sliding direction of the sliding seat 13 can be along the vertical direction, the sliding seat 13 is in the lowest position under the action of gravity, at this time, the reflector 12 is located in the propagation path of the laser; when the operator pulls the pull rod 14 along the vertical direction, the sliding seat 13 drives the reflector 12 to rise, and after the position of the pull rod 14 is fixed by the buckle, the reflector 12 is moved out of the propagation path of the laser.

[0044] Of course, the sliding direction of the sliding seat 13 can also be along other directions, such as the horizontal direction, and after the pull rod 14 drives the sliding seat 13 to move to the position, the position of the pull rod 14 is fixed by the buckle.

[0045] Alternatively, referring to Figure 6 The driving member can be selected as a pneumatic cylinder 15, the pneumatic cylinder 15 is arranged on the shell 11, the piston rod of the pneumatic cylinder 15 penetrates through the shell 11 and is connected to the sliding seat 13. The piston rod of the pneumatic cylinder 15 drives the sliding seat 13 to move, and then the position of the sliding seat 13 and the reflector 12 is changed, so that the reflector 12 is moved into / out of the propagation path of the laser.

[0046] In specific implementation, the sliding direction of the sliding seat 13 can be along the vertical direction, the pneumatic cylinder 15 is arranged vertically on the shell 11, when the piston rod of the pneumatic cylinder 15 extends downward, the sliding seat 13 is pushed to descend, so that the reflector 12 is located in the propagation path of the laser; when the piston rod of the pneumatic cylinder 15 is retracted upward, the sliding seat 13 is pulled to ascend, so that the reflector 12 is moved out of the propagation path of the laser.

[0047] Of course, the sliding direction of the sliding seat 13 can also be along other directions, such as the horizontal direction, and the driving direction of the pneumatic cylinder 15 is consistent with the sliding direction of the sliding seat 13.

[0048] Referring to Figure 4 The optical path switching assembly 10 can further include one or more guide members 16, the guide members 16 are arranged in the shell 11, and the sliding seat 13 is arranged to slide on the guide members 16.

[0049] The guide members 16 are used to guide the movement of the sliding seat 13, so that the movement of the sliding seat 13 is more stable. For example, the guide members 16 are selected as guide rods, the number of the guide rods is two, the upper and lower ends of the guide rods are fixed to the inside of the shell 11 through fixing blocks, and the sliding seat 13 is sleeved on the two guide rods, so that the sliding seat 13 can slide along the axial direction of the guide rods.

[0050] In some embodiments, the cigarette laser perforating optical path device further comprises a first fine adjustment assembly 40 and a reflecting assembly 50, one end of the reflecting assembly 50 is communicated with the optical path switching assembly 10, the other end of the reflecting assembly 50 is slidingly connected with the focusing assembly 20, the fine adjustment assembly is fixedly connected with the reflecting assembly 50 and is used to drive the focusing assembly 20 to approach / away from the reflecting assembly 50.

[0051] When the first fine adjustment assembly 40 drives the focusing assembly 20 to approach / away from the reflecting assembly 50, the position of the laser focus will also change. For example, the first fine adjustment assembly 40 is used to drive the focusing assembly 20 to move along the vertical direction, when the focusing assembly 20 is lowered and away from the reflecting assembly 50, the position of the laser focus will also be lowered; when the focusing assembly 20 is raised and approaches the reflecting assembly 50, the position of the laser focus will also be raised.

[0053] The first guide sleeve 60 plays a guiding role, improves the stability of the focusing assembly 20 when sliding, and ensures the accuracy of adjustment. For example, the first guide sleeve 60 is fixed on the reflecting assembly 50, the axial direction of the first guide sleeve 60 is along the vertical direction, and the first fine adjustment assembly 40 is fixed on the first guide sleeve 60 to drive the focusing assembly 20 to move along the vertical direction, thereby changing the position of the laser focus in the vertical direction.

[0055] When the operator rotates the knob 45, the screw rod 42 can be driven to rotate, so that the sliding block 44 moves on the screw rod 42, and then the focusing assembly 20 is driven to move. A scale can be arranged on the fixed plate 41, so that the operator can observe and record the distance of the movement of the sliding block 44, that is, the distance of the movement of the laser focus.

[0056] In some embodiments, the cigarette laser perforating optical path device further comprises a second fine adjustment assembly 70, one end of the reflecting assembly 50 is slidingly connected with the optical path switching assembly 10, the second fine adjustment assembly 70 is fixedly connected with the optical path switching assembly 10 and is used to drive the reflecting assembly 50 to approach / away from the optical path switching assembly 10.

[0057] When the second fine adjustment assembly 70 drives the reflecting assembly 50 to approach / away from the light path switching assembly 10, the position of the laser focus will also change. For example, the second fine adjustment assembly 70 is used to drive the reflecting assembly 50 to move in the horizontal direction, when the reflecting assembly 50 is away from the light path switching assembly 10, the focusing assembly 20 moves with the reflecting assembly 50, and the position of the laser focus will also be away from the light path switching assembly 10; when the reflecting assembly 50 approaches the light path switching assembly 10, the focusing assembly 20 moves with the reflecting assembly 50, and the position of the laser focus will also approach the light path switching assembly 10.

[0058] Further, a second guide sleeve 80 can be provided, the second guide sleeve 80 is communicated with the light outlet of the shell 11, one end of the reflecting assembly 50 is slidingly arranged in the second guide sleeve 80, and the second fine adjustment assembly 70 is used to drive the reflecting assembly 50 to move in the axial direction of the second guide sleeve 80.
