Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of laser marking machines, specifically a high-degree-of-freedom laser marking machine with a laser reflection module. Background Technology
[0002] A laser marking machine uses a laser beam to create permanent marks on the surface of various materials. The marking effect is achieved by evaporating the surface material to expose the deeper material, thus engraving intricate patterns, trademarks, and text. Laser marking machines are mainly classified into CO2 laser marking machines, semiconductor laser marking machines, fiber laser marking machines, and YAG laser marking machines. Laser marking machines are primarily used in applications requiring higher precision and finer details. Applications include electronic components, integrated circuits (ICs), electrical appliances, mobile communications, hardware products, tool accessories, precision instruments, eyeglasses and watches, jewelry, automotive parts, plastic buttons, building materials, and PVC pipes.
[0003] Existing laser marking machines generally use a direct optical path, and perform laser marking operations by making fine adjustments to the marking area through the autonomous offset of the laser generator.
[0004] The existing technical solutions mentioned above have the following drawbacks: the laser marking area is fixed, the marking range is small, and the lens has low degree of freedom. Utility Model Content
[0005] The purpose of this invention is to provide a high-degree-of-freedom laser marking machine with a laser reflection module.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] The system includes a laser marking machine body. The outer wall of the laser marking machine body has a direct optical path outlet. A light path adjustment module, which is rotatably mounted on the outer wall of the laser marking machine body to cooperate with the direct optical path outlet, is also included. The light path adjustment module includes a first cylindrical body rotatably connected to the direct optical path outlet. A first reflective module with a first reflector internally mounted is fixedly installed at the end of the first cylindrical body. A second cylindrical body, perpendicular to the outer wall of the first cylindrical body, is also included. A second reflective module with a second reflector internally mounted is fixedly installed at the end of the second cylindrical body module. The second reflective module is equipped with a marking laser port.
[0008] By adopting the above technical solution, the laser marking machine body emits a marking laser from the optical path direct output hole. The marking laser passes through the first cylinder and enters the first reflection module. Under the reflection of the first reflector, it hits the second reflection module, passes through the second cylinder and enters the second reflection module. Under the action of the second reflector, it exits from the marking laser port. Since the first and second cylinders are rotatably connected, the first reflection module can rotate freely relative to the laser marking machine body, and the second reflection module can rotate freely relative to the first reflection module. The direction of the marking laser can be effectively adjusted through the reflection of the two reflectors, which has a very high degree of freedom and can adapt to the marking needs under different conditions, making the equipment more adaptable.
[0009] Furthermore, the first reflector is at an angle of 135° to the first cylinder, the second reflector is arranged parallel to the first reflector, and the marking laser port is covered with a laser lens.
[0010] By adopting the above technical solution, the optical path is ensured to advance along the designated route in the installation direction of the first and second cylinders, the angle is limited to avoid deviation, and the setting of the laser lens facilitates end-point focusing and effectively improves the marking effect.
[0011] Furthermore, the first and second cylinders are identical telescopic and rotatable structures. Each telescopic and rotatable structure includes a positioning cylinder fixedly connected to the optical path outlet hole and the outer wall of the first reflection module, respectively. A telescopic cylinder is slidably fitted onto the positioning cylinder along its length. A rotating cylinder is rotatably fitted onto the outer wall of the telescopic cylinder. The rotating cylinder is fixedly connected to both the first and second reflection modules. A strip-shaped first guide bar is fixedly provided along the extension direction of the positioning cylinder. A first guide groove matching the first guide bar is provided on the telescopic cylinder. An annular second guide bar is provided on the outer wall of the telescopic cylinder. A second guide groove matching the second guide bar is provided on the inner wall of the rotating cylinder. Several unit holes are arranged along the length direction of the positioning cylinder. A telescopic spring is fixedly connected to the bottom wall of each unit hole. A hemispherical locking protrusion is fixedly provided at the end of the telescopic spring. Several locking grooves matching the locking protrusions are evenly distributed along the length direction of the telescopic cylinder. A locking bolt, threaded through the outer wall of the rotating cylinder, abuts against the telescopic cylinder. A rotating lever is fixedly provided at the outer end of the locking bolt.
[0012] By adopting the above technical solution, the first and second cylinders of the telescopic rotating structure are further telescopically connected on the basis of the original rotational connection. The length of the first and second cylinders can be extended or shortened according to actual needs, further improving the marking range and enhancing adaptability. In use, the outermost rotating cylinder is pulled to drive the telescopic cylinder to slide along the length of the positioning cylinder. At this time, under the action of external force, the hemispherical locking protrusion is squeezed to retract inward. After reaching the designated position, the hemispherical locking protrusion is embedded into the next locking groove under the action of the telescopic spring to complete the positioning and locking. At this time, the friction between the telescopic cylinder and the positioning cylinder increases and is accompanied by a click. The locking bolt is easy to turn with the rotating paddle. When the locking bolt is turned, the locking bolt moves away from or closer to the telescopic cylinder under the action of the thread. When the rotating cylinder rotates to the appropriate angle, the friction keeps the rotating cylinder fixed relative to the telescopic cylinder.
[0013] Furthermore, the first and second cylinders have the same structure. Since the hemispherical locking protrusion is not forcibly locked and there is no limit device between the telescopic cylinder and the positioning cylinder, the telescopic cylinder and the rotating cylinder can be easily disassembled or installed together. This facilitates later maintenance. When only a single reflection is needed for horizontal marking, the second reflection module can be installed on the laser marking machine body, further expanding the freedom of laser marking.
[0014] In summary, the beneficial technical effects of this utility model are as follows:
[0015] 1. It adopts a direct-out aperture optical path adjustment module, a first reflector and a second reflector, thereby producing the effect of freely adjusting the optical path and optical control, thus producing the effect of changing the optical path through two-step reflection, and freely adjusting the laser emission angle in both the horizontal and vertical planes;
[0016] 2. A laser lens is used to further focus the laser, preventing light scattering and explosion in marking quality;
[0017] 3. It adopts a telescopic and rotating structure, and the length of the first and second cylinders can be extended or shortened according to actual needs, thereby further improving the marking range and enhancing adaptability. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.
[0025] 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.
[0026] Please see Figure 1-2 The present invention provides the following technical solution:
[0027] The laser marking machine includes a main body 1, with a direct light path outlet 11 on its outer wall. A light path adjustment module, which rotatably mounts on the outer wall of the main body 1 to the direct light path outlet 11, is also mounted on the outer wall. The adjustment module includes a first cylinder 3 rotatably connected to the direct light path outlet 11, a first reflection module 41 with a first reflector 4 internally mounted on its end, and a second cylinder 5 perpendicular to the outer wall of the first cylinder 3. A second reflection module 61 with a second reflector 6 internally mounted on its end, and a marking laser port 51, which is fitted onto the second cylinder 5, allows the laser marking machine to emit laser light from the direct light path outlet 11. The marking laser passes through the first cylinder 3 and enters the first reflection module 41. Under the reflection of the first reflector 4, it strikes the second reflection module 61, passes through the second cylinder 5, and enters the second reflection module 61. Under the action of the second reflector 6, it exits from the marking laser port 51. Since the first cylinder 3 and the second cylinder 5 are rotatably connected, the first reflection module 41 can rotate freely relative to the laser marking machine body 1, and the second reflection module 61 can rotate freely relative to the first reflection module 41. The direction of the marking laser can be effectively adjusted through the reflection of the two reflectors, which has a very high degree of freedom and can adapt to the marking needs under different conditions, making the equipment more adaptable.
[0028] The first reflector 4 and the first cylinder 3 are at an angle of 135°. The second reflector 6 is set parallel to the first reflector 4. The marking laser port 51 is covered by a laser lens 7 to ensure that the light path advances along the designated route in the installation direction of the first cylinder 3 and the second cylinder 5, and to limit the angle to avoid deviation. The setting of the laser lens 7 facilitates end focusing and effectively improves the marking effect.
[0029] The first cylindrical body 3 and the second cylindrical body 5 are identical telescopic and rotatable structures 9. The telescopic and rotatable structure 9 includes a positioning cylinder 91 fixedly connected to the optical path outlet 11 and the outer wall of the first reflection module 41, respectively. A telescopic cylinder 92 is slidably fitted onto the positioning cylinder 91 along its length. A rotating cylinder 93 is rotatably fitted onto the outer wall of the telescopic cylinder 92. The rotating cylinder 93 is fixedly connected to the first reflection module 41 and the second reflection module 61, respectively. A strip-shaped first guide bar 911 is fixedly provided along the extension direction of the positioning cylinder 91. The telescopic cylinder 92 has an opening that matches the first guide bar 911. The first guide groove 912, the outer wall of the telescopic cylinder 92 is provided with an annular second guide strip 921, the inner wall of the rotating cylinder 93 is provided with a second guide groove 922 that matches the second guide strip 921, the positioning cylinder 91 is provided with a plurality of unit holes 913 along the length direction, the bottom wall of the unit hole 913 is fixedly connected with a telescopic spring 914, the end of the telescopic spring 914 is fixedly provided with a hemispherical locking protrusion 915, the telescopic cylinder 92 is provided with a plurality of locking grooves 916 that match the locking protrusions 915 evenly distributed along the length direction, and the outer wall of the rotating cylinder 93 is threaded through. A locking bolt 923 is provided to engage the telescopic cylinder 92. A rotating paddle 924 is fixedly installed at the outer end of the locking bolt 923. The first cylinder 3 and the second cylinder 5 of the telescopic rotating structure 9 are further telescopic based on the original rotating connection. The length of the first cylinder 3 and the second cylinder 5 can be extended or shortened according to actual needs, further improving the marking range and enhancing adaptability. In use, pulling the outermost rotating cylinder 93 will cause the telescopic cylinder 92 to slide along the length direction of the positioning cylinder 91. At this time, under the action of external force, the hemispherical locking protrusion 91 is squeezed. 5. When the cylinder retracts inward to the designated position, the hemispherical locking protrusion 915 is inserted into the next locking groove 916 under the action of the telescopic spring 914 to complete the positioning and locking. At this time, the friction between the telescopic cylinder 92 and the positioning cylinder 91 increases and is accompanied by a click. The locking bolt 923 is easy to turn with the rotating paddle 924. When the locking bolt 923 is turned, the locking bolt 923 moves away from or closer to the telescopic cylinder 92 under the action of the thread. When the rotating cylinder 93 rotates to the appropriate angle, the rotating cylinder 93 is kept fixed relative to the telescopic cylinder 92 by the friction.
[0030] Furthermore, the first cylinder 3 and the second cylinder 5 have the same structure. Since the hemispherical locking protrusion 915 is not forcibly locked and there is no limit device between the telescopic cylinder 92 and the positioning cylinder 91, the telescopic cylinder 92 and the rotating cylinder 93 can be easily disassembled or installed together. This facilitates later maintenance. When only a single reflection is needed for marking in the horizontal direction, only the second reflection module 61 needs to be installed on the laser marking machine body 1, further expanding the freedom of laser marking.
