[0045] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0046] like Figures 1 to 3 An external laser processing device includes a main body 1, which is unique in that the main body 1 is fitted with a housing 2. During implementation, the housing 2 is fixed to the aluminum alloy frame attached to the main body by bolts. The housing thickness is ≥2mm and the inner wall can be covered with an electromagnetic shielding layer. An optical platform 3 is distributed on one side of the main body 1, and an external laser device is mounted on the optical platform 3. At the same time, a marble component 4 is mounted on the main body 1, and an optical path docking device is mounted on the marble component 4. This invention has a light guide hole 5 at the light-receiving end of the housing 2 located at the optical path docking device. The light guide hole 5 is rectangular or elliptical in shape. The emitting end of the external laser device corresponds to the light-receiving end of the optical path docking device through the light guide hole 5. Thus, the laser emitted from the external laser device can be smoothly introduced into the main body 1, realizing the external laser source supply. Different external laser devices can be selected and adjusted according to different laser processing needs. Furthermore, during implementation, auxiliary shielding covers can be installed on the outer shell 2 and the optical platform 3 without obstructing the light guide hole 5, which can achieve appropriate protection and avoid exposure of the laser light path, thereby improving safety.

[0047] For ease of use and processing, a guide adjustment device 7 is installed on the gantry 6, and an optical path output device 8 is installed on the guide adjustment device 7, which is connected to the optical path adjustment device. This allows control over the working height of the optical path output device 8 to accommodate different horizontal positions of the workpiece, improving the precision of laser processing. Simultaneously, an adjustable bearing device is installed on the marble assembly 4, and a working platform 9 is mounted on the adjustable bearing device. This ensures stable placement of the workpiece and allows for appropriate displacement adjustment, meeting the needs of multi-point processing.

[0048] During implementation, to allow for rapid adjustment of various parameters such as laser power, the external laser device is a dual-optical-path device. It includes a first laser 10 and a second laser 11 mounted on an optical platform 3. Each of the excitation ports of the first laser 10 and the second laser 11 has a corresponding first external optical cavity 12 and a second external optical cavity 13 installed thereon. Furthermore, the optical path docking device includes a first internal optical cavity 14 corresponding to the output end of the first external optical cavity 12, and a second internal optical cavity 15 corresponding to the output end of the second external optical cavity 13. This allows for a stable inward inflow of the external laser source.

[0049] Meanwhile, to achieve convenient allocation and control, a control device 16 is installed on the equipment body 1. The control device 16 is electrically connected to the external laser equipment, the guide adjustment device 7, the optical path output device 8, and the adjustment support device. Furthermore, considering the convenience of actual user operation, processing parameters can be adjusted in real time as needed, and the current processing progress can be monitored. The control device 16 is also connected to a control device, which is installed on the outside of the outer shell 2 of the equipment body 1. In a preferred embodiment of this utility model, the optical platform 3 includes a platform support, on which a positioning plate is installed. Several insertion holes are distributed on the positioning plate, and several elevation brackets 17 are connected to the insertion holes. The external laser equipment is connected to the corresponding elevation bracket 17. This allows for adjustment of the installation position of the external laser equipment according to the actual optical path direction without interference. Furthermore, the elevation brackets 17 can be used for better coordination and space allocation to meet the layout requirements of dual optical paths. During use, rapid and stable positioning can be achieved through insertion, facilitating initial debugging and calibration.

[0050] Furthermore, to coordinate the guiding configuration of the dual optical paths, the optical path adjustment device includes a first reflective component 18 and a second reflective component 19, as well as a first optical path transmission component 20 and a second optical path transmission component 21, mounted on the gantry 6. Specifically, the input end of the first reflective component 18 is connected to the emitter of the first built-in optical cavity 14, and the input end of the second reflective component 19 is connected to the emitter of the second built-in optical cavity 15. Simultaneously, the emitter of the first reflective component 18 is connected to the optical path output device 8 via the first optical path transmission component 20, and the emitter of the second reflective component 19 is connected to the optical path output device 8 via the second optical path transmission component 21. Thus, during subsequent use, the optical path output device 8 can select different optical paths as needed to meet processing requirements under different power consumption levels. Considering the need for fine-tuning the optical path direction and improving transmission accuracy, both the first reflective component 18 and the second reflective component 19 are connected to the gantry 6 via independent adjustment brackets (not shown in the figure).

[0051] Specifically, the adjustment bracket includes a support rod connected to the gantry 6, with a mounting block connected to the support rod. The mounting block is connected to the corresponding first reflective component 18 or second reflective component 19. Furthermore, the mounting block can be equipped with a ball joint, allowing for ±2° angle adjustment, and can be locked with a lock nut. This allows for adjustments to the actual installation height and orientation angle of the first reflective component 18 and the second reflective component 19. Moreover, the optical path transmission assembly includes a mounting bracket connected to the gantry 6, with a transmission lens assembly connected to the mounting bracket. Thus, while ensuring a stable connection, the orientation of the transmission lens assembly can be adjusted according to actual needs, ensuring that its output optical path is accurately input into the optical path output device 8. For ease of implementation, both the first reflective component 18 and the second reflective component 19 include a mounting frame, within which a reflector assembly is installed. The reflector assembly and transmission lens assembly used in this invention can be commercially available products, reducing manufacturing costs. To optimize this invention, a 10.6μm dual-band anti-reflection film can be coated on the reflective surface of the reflector assembly.

[0052] In practical implementation, the guide adjustment device 7 is a Z-axis linear motor, enabling multi-point guidance along the Z-axis. Meanwhile, the optical path output device 8 is a laser cutting head with a switchable optical path configuration, capable of meeting the needs of conventional dual-optical-path cutting. For ease of implementation, it can utilize readily available dual-optical-path laser cutting heads or equivalent devices, which will not be elaborated further here.

[0053] Furthermore, the adjustable bearing device used in this invention includes an X-axis linear motor 22 connected to the marble component 4. A Y-axis linear motor 23 is connected to the drive end of the X-axis linear motor 22. Guide rails 24 are movably connected to both sides of the Y-axis linear motor 23, and the guide rails 24 are connected to the marble component 4. A work platform 9 is mounted on the drive end of the Y-axis linear motor 23. This allows for convenient displacement adjustment of the workpiece located on the work platform 9, enabling rapid switching between different processing points without manual intervention, thus improving processing safety and efficiency. Moreover, the control device 16 is an industrial control computer. Appropriate commercially available models can be selected according to layout requirements, reducing implementation costs.

[0054] During use, only the corresponding control software needs to be matched according to the current hardware environment and usage process, reducing the difficulty of implementation and debugging. Meanwhile, the control device includes a connecting bracket 25 connected to the device body 1, on which a keyboard 26 and a display 27 are mounted. This allows for appropriate adjustment of their installation positions for user convenience. Furthermore, the keyboard 26 and display 27 are connected to the control device 16, enabling convenient external control and parameter viewing.

[0055] The working principle of this utility model is as follows: The user selects a first laser 10 and a second laser 11 with appropriate power according to the actual processing needs of the workpiece, facilitating rapid switching between dual light sources and multiple power levels. Then, the corresponding first external optical cavity 12 and second external optical cavity 13 are placed on the optical platform 3. During debugging, the first internal optical cavity 14 and second internal optical cavity 15 attached to the device body 1 are ensured to smoothly receive the corresponding optical paths. Next, the workpiece is placed on the work platform 9, and the workpiece is moved into the appropriate processing area by adjusting the carrying device. Subsequently, the optical path output device 8 is adjusted via the guide adjustment device 7. This improves the workpiece's outline to achieve multi-point processing without processing dead angles. For some special workpiece processing needs, the work platform 9 can be replaced with a turntable with a steering drive to meet 360° processing adjustment requirements. Finally, the corresponding processing parameters are entered or selected via the control device.
