Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and more specifically, to a dual-source laser processing device. Background Technology

[0002] Laser processing utilizes a laser beam of appropriate energy density, focused on the workpiece surface, to scan the target surface, causing physical or chemical changes in the material to achieve the processing purpose. Typically, different workpiece materials require different laser wavelengths for surface processing. Current laser processing equipment cannot automatically identify the currently assembled field lens information, nor can it adaptively set system parameters to match the field lens. Relying entirely on manual parameter setting cannot completely eliminate the risk of human error leading to incorrect parameters. Furthermore, the basic information of the field lens is mostly marked on its outer surface; over time, this information may become blurred or even lost, making it difficult to set accurate system parameters. Utility Model Content

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a dual-source laser processing device that has the advantages of automatically identifying the assembled field lens information and automatically setting system parameters that match the field lens, as well as reducing pollution to the surrounding environment during processing. This solves the problems of existing devices having difficulty in accurately setting system parameters and being unable to control pollution during processing.

[0004] (II) Technical Solution To achieve the goals of automatically identifying assembled field lens information, reducing the difficulty of system parameter settings, and minimizing environmental pollution during processing, this utility model provides the following technical solution: A dual-source laser processing device, comprising a worktable and a headstock mounted above the worktable.

[0022] Display component 2 is used to display the current working status of the laser processing equipment. The screen has a touch function and is equipped with touch buttons to control the raising and lowering of the headstock 3 and the automatic focusing function. The camera module 202 is used to capture the image of the worktable 1 and monitor the laser processing process in real time. The laser ranging module 203 is used to test the distance between the headstock 3 and the worktable 1 and to provide feedback on the test value.

[0023] The beam combining optical path module 4 includes an optical path support structure 401 disposed inside the headstock 3, a blue light source 402 disposed on one side of the optical path support structure 401, a reflective optical module 403 disposed at the bottom of the optical path support structure 401 for aligning the optical axes of the red and blue lasers to improve laser processing accuracy, and a field lens module 404 disposed on the other side of the optical path support structure 401. The field lens module 404 includes laser field lenses with different focal lengths, which can converge the red and blue lasers to the processing surface for laser processing of the workpiece.

[0024] In this embodiment, the lifting assembly includes a motor 501 mounted on an inner column of the machine base, a transmission sprocket 502 mounted on one side of the motor 501, front and rear bearing fastening seats 503 mounted on the transmission sprocket 502, a transmission screw 504 mounted on the front and rear bearing fastening seats 503, and a fixed slider 505 mounted on the transmission screw 504. In the lifting assembly, the fixed slider 505 is connected to the outer column assembly of the machine base and does not move. The transmission screw 504 passes through the fixed slider 505 and is connected to the front and rear bearing fastening seats 503. When the machine head base 3 moves up and down, the transmission screw 504 and the front and rear bearing fastening seats 503 move up and down together.

[0026] In this embodiment, the display component 2 also includes an emergency stop switch 204 disposed on the machine head base 3. The emergency stop switch 204 is used to immediately disconnect the power supply of the laser processing equipment in an emergency, stop the equipment from working, and avoid losses and personal injury.

[0027] In this embodiment, a galvanometer driver 405 is provided on one side of the field lens module 404, and an optical galvanometer 407 is provided on the other side of the field lens module 404. The field lens module 404 is also provided with a field lens identification contact 406, which is used to identify field lens information and realize the scanning of the laser processing beam within the processing area.

[0028] Specifically, the working principle of this dual-source laser processing equipment is as follows: During operation, the laser processing equipment is powered on and the workpiece to be processed is placed on the worktable 1. As needed, accessories are used to fix the workpiece to be processed through the threaded holes on the worktable 1 and bolts. Subsequently, the user selects the autofocus function or manually controls the lifting of the headstock 3 to make the distance value obtained by the laser ranging module 203 the same as the working distance; the user connects to an external computer or other electronic device through the interface board 509 to input the file or pattern to be laser processed, and the main control board 201 controls the red light source 510 or the blue light source 402 to output laser. The laser passes through the beam combining optical path module 4 and the galvanometer driver 405, and is emitted by the field lens module 404, converging on the surface of the workpiece to be processed to achieve laser processing; During beam transmission, the main control board 201 controls the galvanometer driver 405 to achieve two-dimensional deflection of the beam, achieving the laser movement trajectory preset for laser processing. During the preparation, execution, and end stages of processing, the display component 2 will display the corresponding working status through graphics or text. During the preparation stage, the main control board 201 can control the blue light source 402 to output low-power blue laser light, which reaches the surface of the workpiece after passing through the aforementioned optical path. At this time, the workpiece surface will not be processed or damaged, realizing the preview function of the processing area and providing users with a visual display of the processing effect before formal processing. During the processing, the exhaust fan 507 installed on the machine base column component 5 will suck away the exhaust gas in the working area to keep the processing area clear. During the process of changing the field lens in the laser processing equipment, the user installs the field lens module 404 into place via the threaded interface. If it is a field lens that comes with the equipment, the protruding part of the field lens will contact the field lens identification contact 406 module. Depending on the model of the field lens, the contact position of the field lens identification contact 406 module will be different, and the generated signal will also be different. If it is a field lens from another brand, it will not contact the field lens identification contact 406 module. Based on the above different situations, the main control board 201 can determine the model of the field lens or whether it is a field lens from another brand, and set the working parameters of the processing equipment according to the judgment result to automatically reach the working state.

[0029] The power supply and principles of the display component 2, main control board 201, camera module 202, laser ranging module 203, blue light source 402, field lens recognition contact 406, motor 501, cooling fan 506, smoke exhaust fan 507, and red light source 510 are clear to those skilled in the art and will not be described in detail here.
