Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laser equipment, and specifically relates to a laser equipment for processing on the surface of brittle and hard materials. Background Technique
[0002] The laser equipment focuses the laser beam on the surface of the material through a focusing lens, uses the high energy density of the laser to instantaneously vaporize or melt the irradiated area, and blows off the generated slag powder through auxiliary means, so as to form a smooth processing surface on the material surface. Since the laser beam and the material are non-contact processing, it is not easy to scratch the surface of the workpiece, and generally no subsequent processing is required.
[0003] When the existing laser equipment processes the surface of brittle and hard materials, the cut position is always prone to roughness after processing, resulting in the phenomenon that the processing quality cannot meet the requirements. The main reason for this phenomenon is that when the surface of the brittle and hard material is subjected to high-temperature cutting by the laser beam, the temperature at the cut position rises suddenly. Based on the fragile characteristics of the brittle and hard material, under such conditions of thermal expansion and contraction, the temperature difference between the two sides of the cut position is too large and the stress is too large, resulting in the cut being damaged. Aiming at the deficiencies of the existing technology, the utility model provides a laser equipment for processing on the surface of brittle and hard materials to solve the above problems. Content of the Utility Model

[0021] By providing a laser device for processing on the surface of brittle and hard materials in the embodiments of the present application, the problem that when the surface of brittle and hard materials is subjected to high-temperature cutting by a laser beam, the temperature at the incision position suddenly rises, and based on the fragile characteristics of brittle and hard materials, under such conditions of thermal expansion and contraction, the temperature difference on both sides of the incision position is too large and the stress is too large, resulting in the collapse of the incision is solved.
[0022] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation manners.
[0023] An embodiment of the present utility model discloses a laser device for processing on the surface of brittle and hard materials. As shown in the attached Figures 1-4 figure, it includes a manipulator main body 1, a laser cutting head 2 fixedly connected to the manipulator main body 1, an external mounting bracket 3 movably clamped to the manipulator main body 1, an angle adjustment component 4 provided on the external mounting bracket 3, a preheating laser head 5 provided on the angle adjustment component 4, and a docking mechanism 6 provided between the manipulator main body 1 and the external mounting bracket 3;
[0024] The angle adjustment component 4 includes a ball seat 401 provided on the external mounting bracket 3 and an adjusting ball 402 movably clamped inside the ball seat 401. The adjusting ball 402 is fixedly connected to the preheating laser head 5, and a clamping bolt 403 is threadedly connected to the ball seat 401. The clamping bolt 403 is in contact with the adjusting ball 402.
[0025] Through the design of the angle adjustment component 4 and the preheating laser head 5, when the device cuts the surface of brittle and hard materials with a laser, the preheating laser head 5 can be used to preheat both sides of the cutting line through the angle adjustment component 4, ensuring that during subsequent laser cutting, the incision is not easily damaged due to excessive temperature difference, reducing the roughness of the incision, and ensuring good cutting quality;
[0026] When adjusting the angle of the preheating laser head 5 using the angle adjustment component 4, first loosen the clamping bolt 403, and then directly move the preheating laser head 5 to adjust the angle of the preheating laser head 5 to the target position. When the preheating laser head 5 moves, it will drive the adjustment ball 402 to rotate inside the ball seat 401. When the preheating laser head 5 is adjusted to the target position, simply tighten the clamping bolt 403.
[0027] The docking mechanism 6 includes a clamping base 601 fixedly connected to the main body of the robotic arm 1 and a plug 602 fixedly connected to the external mounting frame 3. The plug 602 is movably clamped inside the clamping base 601. The designed docking mechanism 6 in this device has a simple structure. The docking mechanism 6 is used to quickly load the external mounting frame 3 onto the main body of the robotic arm 1, so that when machining the surface of brittle and hard materials, the external mounting frame 3, the angle adjustment component 4, and the preheating laser head 5 can be quickly installed. When machining other materials, it is also convenient to disassemble the preheating laser head 5.
[0028] A guide rod 603 is fixedly connected to the clamping base 601. A slider 604 is slidably connected to the guide rod 603. A positioning rod 605 is fixedly connected to the slider 604. A positioning socket 6021 is formed on the plug 602. The positioning rod 605 is movably clamped inside the positioning socket 6021. A baffle 606 is fixedly connected to the guide rod 603. A spring 607 is fixedly connected between the baffle 606 and the slider 604. A pull rod 608 is fixedly connected to the slider 604. The pull rod 608 passes through the baffle 606 and extends outward.
[0029] When realizing the quick loading of the external mounting frame 3 onto the main body of the robotic arm 1 through the docking mechanism 6, first pull the pull rod 608, so that the pull rod 608 drives the slider 604 and the positioning rod 605 to move and compress the spring 607. At this time, insert the plug 602 into the inside of the clamping base 601 to fix the positions of the external mounting frame 3, the angle adjustment component 4, and the preheating laser head 5. Finally, release the pull rod 608, so that the spring 607 resets and pushes the slider 604 and the positioning rod 605 to move, and the positioning rod 605 is inserted into the positioning socket 6021 to fix the external mounting frame 3, the angle adjustment component 4, and the preheating laser head 5, ensuring the convenient disassembly and assembly of the preheating laser head 5.
