Detailed implementation manners

[0054] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0055] The present invention provides a multi-field laser cutting and engraving device, such as Figures 1 to 4As shown in the figure, it includes a device body 1, a first mounting plate 2, a second mounting plate 3, a mounting sleeve 4, a laser head 5 and a mounting limiting device. The device body 1 includes a base, a placing plate 6, a moving guide rail frame 7 and a driving device 8. A placing plate 6 is slidably arranged on the top of the base for placing the material to be cut. The moving guide rail frame 7 is fixedly installed on the top of the base, and a driving device 8 is arranged on the moving guide rail frame 7. The first mounting plate 2 and the second mounting plate 3 are slidably arranged on the moving guide rail frame 7 through the driving device 8. The pneumatic buffer device is connected to the moving guide rail frame 7 through the second mounting plate 3. The first mounting plate 2 and the second mounting plate 3 are fixedly connected on one side. The mounting sleeve 4 is arranged on one side of the first mounting plate 2 through the mounting limiting device. A laser head 5 is arranged in the mounting sleeve 4. A cutting tool can also be installed on one side of the first mounting plate 2. The laser head 5 or the cutting tool is installed through the first mounting plate 2 and the mounting limiting device. By starting the driving device 8 to drive the first mounting plate 2 and the second mounting plate 3 to move along the moving guide rail frame 7, the pneumatic buffer device can move simultaneously with the laser head 5 or the cutting tool, facilitating cutting and carving of different materials. The mounting limiting device includes a mounting seat 9, a fixing block 10, a bolt 11 and a limiting component. The fixing block 10 is fixedly connected to one side of the first mounting plate 2. The fixing block 10 is arranged in the mounting seat 9. One side of the fixing block 10 is fixedly connected to the mounting sleeve 4. Thread grooves are formed in the middle of the fixing block 10 and the mounting seat 9. The bolt 11 is arranged on one side of the fixing block 10 and the mounting seat 9. The bolt 11 is threadedly connected to the fixing block 10 and the mounting seat 9 through the thread grooves. The limiting component is arranged on the mounting seat 9 for limiting and fixing the mounting sleeve 4.

[0056] When a cutting tool is installed on the first mounting plate 2, the cutting tool is connected through the pneumatic buffer device. When the driving device 8 drives the first mounting plate 2 and the second mounting plate 3 to move, the cutting tool can move to a specified position for precise cutting, and at the same time, after cutting is completed, the cutting tool is pushed back to its original position.

[0057] When installing the laser head 5, by placing the fixing block 10 in the middle of the fixing seat, pushing the fixing block 10 drives the mounting sleeve 4 and the laser head 5 to move upward, so that the fixing block 10 pushes the limiting component to move, enabling the limiting component to limit the positions of the fixing block 10 and the mounting sleeve 4. The mounting sleeve 4 facilitates the protection of the laser head 5, preventing the laser head 5 from being damaged by collision and affecting its use. Then, insert the bolt 11 into the internal thread groove. By moving the limiting component, the bolt 11 is limited, and thus the fixing block 10, the mounting sleeve 4, and the laser head 5 are installed on the first mounting plate 2, ensuring the stable installation of the laser head 5 and the mounting sleeve 4 and preventing the bolt 11 from rotating, which may affect the stability of the mounting sleeve 4 and the laser head 5. Start the driving device 8 to make the first mounting plate 2 drive the mounting sleeve 4 and the laser head 5 to move, enabling the laser head 5 to perform cutting and carving. Prevent the mounting sleeve 4 from shaking and driving the laser head 5 to shake, which is conducive to improving the cutting and carving effect. At the same time, the equipment body 1 can perform cutting and carving both through the cutting tool and through the laser head 5, and is applied to various industrial fields with different materials, improving the applicability.

[0058] As Figures 1 to 2 shown, in order to monitor the position of the cutting tool, control the speed of the cutting tool, facilitate the cutting tool to return to its original position, and prevent the cutting tool from being collided, the pneumatic buffer device includes an air source control component 12, a cylinder 13, and a sensor 14. The air source control component 12 is arranged at one end of the moving guide rail frame 7 away from the driving device 8. One side of the cylinder 13 is fixedly installed with the second mounting plate 3. The cylinder 13 is slidably arranged on one side of the moving guide rail frame 7 through the second mounting plate 3. The cylinder 13 is arranged on one side of the mounting sleeve 4. The cylinder 13 is connected to the cutting tool and is used to push the cutting tool to move. The sensor 14 is arranged at the other end of the moving guide rail frame 7 away from the driving device 8. The sensor 14 is arranged opposite to the cutting tool and is used to detect the position of the cutting tool.

[0059] When the cutting tool needs to perform cutting and carving, set the cutting parameters such as cutting speed and pressure through the air source control component 12. When compressed air enters the inside of the cylinder 13, the cylinder 13 moves to push the cutting tool to move to the specified position for precise cutting. During the cutting process, the sensor 14 monitors the position of the cutting tool in real time to ensure the cutting accuracy and quality. After the cutting is completed, the air source control component 12 makes the cylinder 13 stop operating, and then drives the cutting tool to return to the initial position, thereby preventing the cutting tool from being collided when the cutting tool is installed on the first mounting plate 2 for cutting and carving, and improving the cutting and carving efficiency.

[0060] As Figures 3 to 8As shown in the figure, in order to improve the stability of the connection between the fixed block 10, the mounting seat 9 and the bolt 11, prevent the bolt 11 from shaking, and prevent the mounting sleeve 4 from driving the laser head 5 to shake, which affects the stability of the laser head 5 during cutting and engraving, the limiting assembly includes a groove, a moving block 15, a limiting plate 16, a first elastic member, a pushing plate 17 and a connection limiting mechanism. A groove is formed in the middle of one side of the mounting seat 9 close to the mounting sleeve 4. The moving block 15 is slidably connected to the inner wall of the groove. The moving block 15 is connected to the inner wall of the top of the groove through a first elastic member. The limiting plate 16 is arranged at the bottom of the moving block 15. One end of the pushing plate 17 is hinged to the limiting plate 16, and the other end is hinged to the moving block 15. Activity openings are formed on both sides of the mounting seat 9. The limiting plate 16 and the pushing plate 17 are both arranged in the activity openings. The bottom of the limiting plate 16 is slidably connected to the inner wall of the activity opening. The pushing plate 17 is located in the activity opening above the limiting plate 16. The pushing plate 17 is convenient for pushing the limiting plate 16 to move. The connection limiting mechanism is connected to one side of the limiting plate 16 and is used to fix the positions of the limiting plate 16 and the bolt 11. The connection limiting mechanism includes a connecting rod 18, a movable plate 19 and a limiting rod 20. One end of the connecting rod 18 is fixedly connected to one side of the limiting plate 16. The movable plate 19 is fixedly connected to the other end of the connecting rod 18. The movable plate 19 is located on both sides of the mounting seat 9. The limiting rod 20 is connected to the movable plate 19 close to the bolt 11. A slot is formed at the bottom of the bolt 11. The limiting rod 20 is inserted into the bolt 11 through the slot. The number of the limiting plate 16, the connecting rod 18 and the movable plate 19 is two. An arc-shaped groove is formed at the top of the movable plate 19 close to the bolt 11. The limiting rod 20 is located in the middle of the arc-shaped groove. The inner wall of the arc-shaped groove is close to the outer wall of the bolt 11.

[0061] In the initial state, the moving block 15 is located at the inner bottom end of the groove, the two ends of the limiting plate 16 are far away from each other, and the pushing plate 17 is in an inclined state. Both ends of the limiting plate 16 and one end of the pushing plate 17 extend to the outside of the mounting seat 9 through the movable opening. The two sides of the movable plate 19 away from the mounting seat 9 are close to one side of the bolt 11. The movable plate 19 on the side close to the bolt 11 is a telescopic movable plate. The arc-shaped groove is located at the telescopic end, and the telescopic movable plate is in a contracted state. When the laser head 5 needs to be installed, the fixing block 10 is placed into the inner part of the groove, and the fixing block 10 is pushed to move upward along the inner wall of the groove. The fixing block 10 pushes the moving block 15 upward to compress the first elastic member, and the first elastic member can be a compression spring. When the moving block 15 moves, it drives the pushing plate 17 to deflect, and then pushes the limiting plates 16 to move closer to each other. A limiting groove is formed on one side of the left limiting plate 16 away from the pushing plate 17, and a limiting rod 20 is fixedly connected to one side of the right limiting plate 16 away from the pushing plate 17. The limiting groove is inserted with the limiting rod. When the moving block 15 moves to the top end of the inner wall of the groove, the pushing plate 17 rotates to the vertical state, and then the limiting plates 16 move to the bottom of the fixing block 10, so that one side of the limiting plates 16 is in contact with each other. At the same time, the limiting rod is inserted into the limiting groove to limit the position of the fixing block 10. When the limiting plates 16 move along the inner wall of the movable opening to the bottom of the fixing block 10, the movable plate 19 is driven to approach and fit the outer wall of the mounting seat 9 through the action of the connecting rod 18. Then, the bolt 11 is threadedly connected to the threaded grooves of the fixing block 10 and the mounting seat 9. The movable plate 19 at the bottom of the bolt 11 is moved upward, so that the limiting rod 20 is inserted into the slot at the bottom of the bolt 11, and the arc-shaped groove of the movable plate 19 is close to the outer side of the bottom end of the bolt 11, so that the bolt 11 is fixed. Further, the fixing block 10 drives the mounting sleeve 4 and the laser head 5 to be installed on the first mounting plate 2, preventing the bolt 11 from shaking and affecting the stability of the laser head 5 inside the mounting sleeve 4, and improving the carving accuracy of the laser head 5.

[0062] As Figure 5 , Figure 10As shown in the figure, in order to limit and support the laser head 5 and prevent the laser head 5 from vibrating and shaking during use in the mounting sleeve 4, which may affect the cutting and engraving effect of the laser head 5, a fixing plate 34 is fixedly connected to the outside of the laser head 5. A support and cooling assembly is provided inside the fixing plate 34. The support and cooling assembly includes an electric push rod 21, a first connecting plate 22, a cooling block 23, a support block 24, a second connecting plate 25 and a gear and rack mechanism. Two moving slots are opened at the top of the fixing plate 34. The electric push rod 21 is arranged in the mounting slot inside the fixing plate 34. One side of the electric push rod 21 is fixedly installed on the inner wall of the mounting slot. One end of the electric push rod 21 is fixedly connected to the first connecting plate 22. The cooling block 23 is fixedly connected to the side of the electric push rod close to the first connecting plate 22 and is used to cool the outside of the laser head 5. The support block 24 is arranged at the moving opening on one side of the electric push rod 21. One side of the support block 24 is fixedly connected to the second connecting plate 25. The first connecting plate 22 and the second connecting plate 25 are connected by a gear and rack mechanism. The electric push rod 21, the first connecting plate 22, the second connecting plate 25, the cooling block 23 and the support block 24 are all symmetrically arranged with the center of the fixing plate 34, improving the stability of the limitation of the laser head 5 from both sides of the laser head 5. Moving openings are opened on both sides of the fixing plate 34 for the support block 24 to move and limit the position of the fixing plate 34.

[0063] The gear and rack mechanism includes a first rack 26, a gear 27, a rotating rod 33 and a second rack 28. One side of the first rack 26 is connected to the first connecting plate 22. The second rack 28 meshes with a gear 27 on one side. A rotating rod 33 is fixedly connected to the middle of the gear 27. The rotating rod 33 is rotatably connected to the inner wall of the moving slot. The gear 27 meshes with the second rack 28 on one side. One side of the second rack 28 is fixedly installed on the second connecting plate 25. The bottoms of the first rack 26, the second rack 28, the first connecting plate 22, the second connecting plate 25, the support block 24 and the cooling block 23 are all movably connected to the inner wall of the bottom of the moving slot.

[0064] After the mounting sleeve 4 is connected to the mounting base 9 through the fixing block 10 and fixed on the first mounting plate 2, the laser head 5 is mounted and limited. Then, the electric push rod 21 inside the mounting groove is started to drive the first connecting plate 22 and the cooling block 23 to move along the inner wall of the bottom of the mounting groove, so that the first connecting plate 22 drives the first rack 26 to move, the gear 27 drives the rotating rod 33 to rotate along the inner wall of the mounting groove, and the second rack 28 drives the second connecting plate 25 and the support block 24 to move along the inner wall of the bottom of the mounting groove in the direction opposite to that of the cooling block 23. When the cooling block 23 moves to both sides of the laser head 5 and fits against its outer wall, the support block 24 moves from the moving port to the inner wall of the mounting sleeve 4 and fits against the inner wall of the mounting sleeve 4 for limitation, thereby improving the stability of the installation of the fixing plate 34, keeping the laser head 5 on the fixing plate 34 stable, reducing the influence caused by vibration, and when the cooling block 23 fits against both sides of the laser head 5, it can not only support and limit but also further cool and dissipate heat from the outside of the laser head 5, improving the service life of the laser head 5.

[0065] As Figure 3 , Figure 5 , Figure 9 shown, a heat dissipation member is provided on the top of the laser head 5. In order to prevent the uneven heat dissipation of the heat dissipation member to the laser head 5 from affecting the heat dissipation effect of the laser head 5, a heat dissipation assembly is provided on one side of the laser head 5. The heat dissipation assembly is located on the fixing plate 34. The heat dissipation mechanism includes a mounting block 29, a cooling box 30 and an adjusting mechanism. The mounting block 29 is fixedly connected to the fixing plate 34. The cooling box 30 is fixedly connected inside the mounting block 29. Cold air is provided inside the cooling box 30. A delivery pipe is fixedly connected to one side of the cooling box 30 for delivering cold air to dissipate heat from the laser head 5. An adjusting mechanism is also provided on one side of the mounting block 29. The adjusting mechanism is arranged in an array on one side of the delivery pipe for guiding the delivery of cold air. The adjusting mechanism includes a mounting groove, a first driving member 31 and a guiding plate 32. The mounting groove is opened on the inner walls of both sides of the mounting block 29. The first driving member 31 is fixedly connected to the mounting groove on one side of the inner wall of the mounting block 29. The middle of the guiding plate 32 is fixedly connected to a rotating rod 33. One end of the rotating rod 33 is rotatably connected to the inner wall of the mounting groove on the other side of the inner wall of the mounting block 29. The guiding plate 32 is fixedly connected to the first driving member 31 through the rotating rod 33 for adjusting the angle and direction of the delivery of cold air.

[0066] The heat dissipation component is a fan. The fan is located at the top of the laser head 5 and is used to dissipate heat from the laser head 5. When the laser head 5 needs to be cooled after long-term use, the heat dissipation component is first activated to dissipate heat from the laser head 5. The first driving component 31 can be a motor. The rotating rod 33 is driven by the first driving component 31 to rotate along the installation groove, causing the guide plate 32 to deflect. According to different parts of the laser head 5, the cooling air is guided, and the effect of cold air delivery is adjusted. Then, the cold air inside the cooling box 30 is delivered to the outside of the laser head 5 through the guide plate 32 via the delivery pipe, facilitating the guiding of the cold air to the laser head 5 for cooling, and cooling the laser head 5 again, thereby improving the usage effect of the laser head 5.

[0067] Working principle: During use, in the initial state, the moving block 15 is located at the bottom end inside the groove. The two ends of the limiting plate 16 move away from each other, and the pushing plate 17 is in an inclined state. Both the limiting plate 16 and one end of the pushing plate 17 pass through the movable opening and extend to the outside of the mounting seat 9. The movable plate 19 is away from both sides of the mounting seat 9, and the movable plate 19 on the side close to the bolt 11 is a telescopic movable plate 19. The arc-shaped groove is located at the telescopic end, and the telescopic movable plate 19 is in a contracted state. When the laser head 5 needs to be installed, the fixing block 10 is placed inside the groove, and the fixing block 10 is pushed to move upward along the inner wall of the groove. The fixing block 10 pushes the moving block 15 upward, squeezing the first elastic member to compress it. The first elastic member can be a compression spring. When the moving block 15 moves, it drives the pushing plate 17 to deflect, and then makes the limiting plates 16 move closer to each other. A limiting groove is provided on the side of the left limiting plate 16 away from the pushing plate 17, and a limiting rod 20 is fixedly connected to the side of the right limiting plate 16 away from the pushing plate 17. The limiting groove and the limiting rod are inserted. When the moving block 15 moves to the top end of the inner wall of the groove, the pushing plate 17 rotates to the vertical state, and then the limiting plates 16 move to the bottom of the fixing block 10, making one side of the limiting plates 16 fit together. At the same time, the limiting rod and the limiting groove are inserted to limit the position of the fixing block 10. When the limiting plates 16 move along the inner wall of the movable opening to the bottom of the fixing block 10, the movable plate 19 is driven by the connecting rod 18 to move closer to and fit against the outer wall of the mounting seat 9. Then, the bolt 11 is threadedly connected to the threaded grooves of the fixing block 10 and the mounting seat 9. The movable plate 19 at the bottom of the bolt 11 is moved upward, so that the limiting rod 20 is inserted into the slot at the bottom of the bolt 11, and the arc-shaped groove of the movable plate 19 is close to the outer side of the bottom end of the bolt 11, fixing the bolt 11. Thus, the fixing block 10 drives the mounting sleeve 4 and the laser head 5 to be installed on the first mounting plate 2.

[0068] Restart the electric push rod 21 inside the installation groove to drive the first connecting plate 22 and the cooling block 23 to move along the inner wall of the bottom of the installation groove, so that the first connecting plate 22 drives the first rack 26 to move, so that the gear 27 drives the rotating rod 33 to rotate along the inner wall of the installation groove, and the second rack 28 drives the second connecting plate 25 and the support block 24 to move along the inner wall of the bottom of the installation groove in the direction opposite to the cooling block 23. When the cooling block 23 moves to both sides of the laser head 5 and fits against its outer wall, the support block 24 moves through the moving port to the inner wall of the installation sleeve 4 and fits against the inner wall of the installation sleeve 4 to limit and support the fixing plate 34.

[0069] When the laser head 5 needs to be cooled after long-term use, first start the heat dissipation component to dissipate heat from the laser head 5, and at the same time cool the outside of the laser head 5 through the cooling block 23. Then start the first driving component 31 to drive the rotating rod 33 to rotate along the installation groove, so that the guide plate 32 deflects. Then, the cold air inside the cooling box 30 is transported to the outside of the laser head 5 through the guide plate 32 through the delivery pipe, and the cold air is guided to the laser head 5 for cooling, and the laser head 5 is cooled again, so that the laser head 5 can continue to be used after the temperature is reduced.
