Description

Technical Field

[0001] This utility model relates to the field of laser engraving technology, and in particular to a laser engraving device for sheet metal. Background Technology

[0002] Laser engraving equipment for sheet metal is a device used to engrave fine patterns and text on the surface of various sheet metals. It plays an important role in many fields of modern manufacturing and handicrafts processing. By focusing the high energy of the laser beam onto the surface of the sheet metal, it instantly vaporizes or melts the local material of the sheet metal, thereby achieving precise engraving. It can meet diverse and high-precision engraving needs, greatly improve the aesthetics of products, and provide strong support for the personalized customization of products in various industries.

[0003] In existing technologies, common sheet metal laser engraving devices consist of a laser emitter, a worktable, and a control device. The laser emitter is responsible for generating a high-energy laser beam, the worktable is used to support the sheet metal and enable precise movement, and the control device regulates the entire engraving process, including laser power, engraving speed, and pattern path parameters. This structure can complete basic engraving tasks to a certain extent, its working principle is relatively clear, and its operation is relatively convenient.

[0004] Existing laser engraving devices for sheet metal have many problems. These devices fix the laser emitter in a specific position and utilize the two-dimensional movement of the worktable to engrave at different locations. This avoids the complex mechanical structure design caused by frequent movement of the laser emitter. However, due to physical limitations on the speed and acceleration of the worktable when carrying the sheet metal, frequent starts and stops and high-speed movements of the worktable lead to decreased positioning accuracy when dealing with complex, intricate patterns requiring rapid changes in engraving position. This makes high-precision engraving difficult. Furthermore, the frequent movement of the worktable over a long period causes wear on mechanical parts, reducing the stability and lifespan of the device and increasing maintenance costs. When processing sheets of different thicknesses, existing devices often require frequent manual adjustments to the laser focusing parameters, which is cumbersome and inefficient, failing to meet the demands of high-efficiency production.

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.

[0034] Reference Figure 1 , Figure 4 and Figure 5A laser engraving device for sheet metal includes a base 1, which provides support. Support columns 3 are fixedly connected to the four corners of the base 1 to improve structural stability. Pads 4 are fixedly connected to the bottom of each support column 3. A movable component is installed on the top of the base 1. An auxiliary plate 15 is fixedly connected to the top of two fixed blocks 10 to improve the stability of the device. Two fixed supports 19 are fixedly connected to the middle of the rear side of the top of the base 1. A rotating shaft 20 is rotatably connected between adjacent fixed supports 19, assisting the rotating shaft 13 in rotating synchronously. The front rotating shaft 13 and the rear... A rotating belt 14 is rotatably connected to the outer wall of the second side rotating shaft 20. The rotating belt 14 performs circular motion. An engraver 17 is rotatably connected inside the rotating belt 14. A support shaft 16 is fixedly connected to the engraver 17, assisting in the stability of the engraver 17. The outer right side of the support shaft 16 is rotatably connected to the inner left side of the auxiliary plate 15. A laser 18 is fixedly connected to the bottom of the engraver 17, and the laser 18 engraves the plate. A hydraulic press 21 is fixedly connected to the top right side of each of the two fixed seats 8. The hydraulic press 21 provides the power for left and right translation. A hydraulic rod 23 is slidably connected to the left side of each of the two hydraulic presses 21. Hydraulic rod 23 is internally slidably connected to hydraulic rod 24. The two hydraulic rods 23 and 24 operate synchronously to ensure stable left-right translation. Fixing plates 25 are fixedly connected to the left side of each hydraulic rod 24, and fixing blocks 10 are threadedly connected to the left side of each fixing plate 25. A dust extraction mechanism 2 is installed at the bottom of the engraver 17. This mechanism improves the safety of the working environment and ensures the accuracy of the engraver 17's operation. The moving components provide stability to the device. A control box 5 is installed on the front exterior of the base 1. The control box 5 provides power and data, and is fixedly connected to the front exterior of the control box 5. There is a controller 6, which can perform control. The top of the base 1 is fixed with a fixed seat 8 threaded on both the front and rear sides. The bottom of the two fixed seats 8 has a pulley, and the top of the two fixed seats 8 is provided with a sliding groove 9. The sliding groove 9 can make the two fixed seats 8 move synchronously. The top of the two fixed seats 8 is slidably connected to a fixed block 10. The front side of the front fixed block 10 is fixedly connected to a fixed block 2 11. The top of the front fixed block 2 11 is fixedly connected to a motor 12, which provides power. The output end of the motor 12 is rotatably connected to a rotating shaft 13. The rotating shaft 13 rotates inside the rotating belt 14 to provide stable power and support.

[0035] Specifically, the material to be carved is placed on the device. The base 1 provides stable support, and the support columns 3 at the four corners further improve structural stability. The pads 4 at the bottom of the support columns 3 increase friction with the ground to prevent the device from moving. The top of the base plate 1 has a moving component. The control box 5 is located on the front side of the base 1, providing power and data. The controller 6 on the front side of the control box 5 is used to operate and control the device. The motor 12 is started and fixed to the top of the front fixing block 11. The rotating shaft 13 connected to the output end rotates inside the rotating belt 14, providing power to the device. The rotating shaft 20 connected to the rear fixing bracket 19 assists the rotating shaft 13 in rotating synchronously, causing the rotating belt 14 to perform circular motion. The engraver 17 rotates with the auxiliary plate 15 via the support shaft 16 and is located on the rotating belt 14. Inside, the laser 18 at the bottom of the engraver 17 performs laser engraving on the board during movement. During the engraving process, the left and right positions of the engraver 17 are adjusted, and two hydraulic presses 21 are activated. The hydraulic presses 21 are fixed on the top right side of the two fixed seats 8. The hydraulic rod 1 23 on the left side and the hydraulic rod 24 inside the wall operate synchronously, providing the device with the power to move left and right, driving the engraver 17 connected to the fixed block 10 to move left and right, achieving precise engraving. The fixed seat 8 has pulleys at the bottom and a sliding groove 9 at the top, which allows the two fixed seats 8 to move synchronously, further assisting the precise operation of the device. The dust extraction mechanism 2 set at the bottom of the engraver 17 promptly removes the dust generated during the engraving process, improving the safety of the working environment, ensuring the accuracy of the engraver 17, and preventing dust from affecting the engraving quality.

[0036] Reference Figure 2 , Figure 3 and Figure 4The dust extraction mechanism 2 includes a fixing ring 201, the top of which is fixedly connected to the bottom of the engraver 17, thus connecting and fixing the dust extraction mechanism 2 to the engraver 17. An air extraction pipe 202 is connected inside the fixing ring 201 to provide a gas channel for dust extraction, allowing dust to be extracted through the air extraction pipe 202. Rubber discs 203 are fixedly connected to the bottom of each of the multiple air extraction pipes 202. The rubber discs 203 can better conform to the surface to be dusted, enhancing the dust extraction effect and preventing dust leakage. Fixing pads 204 are fixedly connected to the top of each of the multiple air extraction pipes 202, assisting in fixing the air extraction pipes 202. Phillips head screws 205 penetrate the interior of each of the multiple fixing pads 204, securing the fixing pads 204 and the air extraction pipes 202. The function is to ensure the reliability of the connection. The top of multiple cross screws 205 all pass through the fixing pad 204 and are threaded to the bottom of the fixing ring 201, so as to achieve a stable connection between the cross screws 205, fixing pad 204, air extraction pipe 202 and fixing ring 201, and ensure the stability of the overall structure. The top right side of the engraver 17 is fixedly connected to the air pipe 206. The air pipe 206 is used to transmit the dust gas collected by the air extraction pipe 202 to the designated location. The bottom of the air pipe 206 is set on the top of the auxiliary plate 15 and the rear side of the fixing block 10, so that the position of the air pipe 206 is clearly defined and the installation is more accurate and reasonable. The bottom end of the air pipe 206 is fixedly connected to the exhaust port 207, which discharges the dust gas transmitted by the air pipe 206, completing the dust extraction process.

[0037] Specifically, the retaining ring 201 serves as the connecting component of the dust extraction mechanism 2. The top of the retaining ring 20 is securely connected to the bottom of the engraver 17, achieving a tight connection between the dust extraction mechanism 2 and the engraver 17. This ensures that the dust extraction mechanism 2 can function when dust is generated during engraving operations. Multiple suction pipes 202 are connected internally to the retaining ring 201, forming a gas channel for dust extraction. During operation, when dust is generated by the engraver 17 engraving an object, the suction pipes 202 begin to work, and the rubber disc 20 at the bottom... 3. The rubber disc 203, being soft and elastic, enhances the dust extraction effect and effectively prevents dust leakage, allowing dust to be collected to the maximum extent by the suction pipe 202. The fixing pad 204 at the top of the suction pipe 202 provides auxiliary fixation. Multiple Phillips head screws 205 penetrate the fixing pad 204, with the top of each screw connecting to the bottom of the fixing ring 201. This fastening method ensures the secure connection between the fixing pad 204, the suction pipe 202, and... The reliability of the connection between the fixed rings 201 maintains the stability of the overall structure, ensuring that the components will not loosen due to vibration or other factors during the dust extraction process, thus affecting the dust extraction effect. As the suction pipe 202 sucks in the dust, the dust-containing gas is transmitted upward along the suction pipe 202. At this time, the vent pipe 206 connected to the top right side of the engraver 17 plays a role. The vent pipe 206 further transmits the dust-containing gas collected by the suction pipe 202. The vent pipe 206 is positioned at the top of the auxiliary plate 15 and the rear side of the rear fixing block 10, making the installation more accurate and reasonable, ensuring a smooth gas transmission path. The exhaust port 207 at the bottom of the vent pipe 206 is responsible for discharging the dust-containing gas transmitted by the vent pipe 206. The discharged gas may be guided to a special dust removal device for further processing according to actual needs, further separating the dust and gas. The purified gas is then discharged into the atmosphere, thus completing the entire dust extraction process, effectively reducing dust pollution in the working environment, protecting the health of operators and the normal operating environment of the working equipment.

[0038] Reference Figure 2 and Figure 5Both hydraulic presses 21 have a fixed plate 22 threadedly connected to their left sides, ensuring a secure connection and providing stable support for subsequent component installation. Each fixed plate 22 has a fixed bolt 29 threadedly connected to its four corners, firmly securing it and preventing loosening, thus enhancing the overall structural stability. Similarly, each fixed plate 25 has a fixed bolt 26 threadedly connected to its four corners, effectively connecting it to the components and ensuring reliable connection. Multiple fixed bolts 26 are also present. The left side of the 6 passes through the fixing plate 25 and is threaded to the outside right side of the two fixing blocks 10, so that the fixing plate 25 and the fixing block 10 are tightly combined, improving the overall structure. The bottom four corners of the multiple pads 4 are threaded with expansion bolts 27, which can firmly fix the pads 4 to the ground, ensuring the stability of the pads 4 and providing a reliable support foundation for the entire device. The left side of the two hydraulic rods 24 is fixedly connected with rubber pads 33, which play a role in buffering and shock absorption, reducing the impact and vibration generated when the hydraulic rods 24 are working, protecting related components and reducing noise.

[0039] Specifically, the hydraulic press 21 provides power for the left and right translation of the equipment. The left side of the hydraulic press 21 is connected to the fixing plate 22 and secured at the four corners of the fixing plate 22 with fixing bolts 29, ensuring the stability of the connection between the fixing plate 22 and the hydraulic press 21 and enabling stable power transmission. The fixing plate 25 is connected to the fixing block 10 with fixing bolts 26. This connection method makes the overall structure of the equipment more stable. The pad 4 is fixed to the ground with expansion bolts 27 at the four corners of the bottom, providing stable support for the entire equipment and ensuring that the equipment will not shift during operation. The hydraulic rod 24 moves in extension and retraction under the drive of the hydraulic press 21. When the hydraulic press 21 is working, the pressure is transmitted to the hydraulic rod 24 through the hydraulic device, and it moves according to the left and right translation direction and stroke. The rubber pad 33 connected to the left side of the hydraulic rod 24 plays a role in buffering and shock absorption, reducing the impact force on the equipment and reducing the noise generated during operation, ensuring the stable operation of the equipment.

[0040] Reference Figure 1 and Figure 2Two indicator lights 30 are fixedly connected to the top front of the auxiliary plate 15. The two indicator lights 30 are equidistant and can clearly and intuitively observe the status of the equipment. A fixed bracket 7 is fixedly connected to the top of the base 1 to provide stable support. The bottom left and right sides of the two fixed seats 8 are threaded with cross bolts 28, which can be tightened or loosened to achieve the fastening and disassembly of the components, which is convenient for the installation and maintenance of the equipment. Multiple switches 31 are fixedly connected to the bottom of the outer side of the controller 6, which can conveniently turn on, off or switch the various functions of the equipment. A CNC screen 32 is fixedly connected to the middle of the outer side of the controller 6 to accurately display the various operating data and parameters of the equipment, so that users can understand the status of the equipment in real time and make adjustments.

[0041] Specifically, when the equipment is working, the base 1 serves as the basic support structure, firmly placed on the working surface, improving the stability of the equipment during operation. The fixed bracket 7 is located on top of the base 1, used to support and position the parts to be processed. The two indicator lights 30 on the front top of the auxiliary plate 15 are designed with equal spacing. When the equipment is in different working states, the indicator lights 30 will intuitively convey the equipment status information to the user through different colors or flashing frequencies. The equipment is always green when running normally, and flashes red when a fault occurs. The two fixed seats 8 can easily fix or disassemble parts by tightening or loosening the cross bolts 28 on the left and right sides of the bottom, which facilitates the assembly, debugging and later maintenance of the equipment. The controller 6 is the control unit of the equipment. The user can issue start, stop and switch operation commands for different functional modules of the equipment through the operation switch 31. The CNC screen 32 on the outer center of the controller 6 will display the operating parameters of the equipment in real time. The user can accurately adjust the operating status of the equipment according to the information displayed on the CNC screen 32 to meet the needs of different working scenarios.

[0042] Working principle: First, the operator turns on the controller 6, activating the circuit components inside the control box 5, providing power and control signals to the entire device. The motor 12 starts, and its output drives the rotating shaft 13 to rotate. During the engraving process, the auxiliary plate 15 provides auxiliary support to the support shaft 16 of the engraver 17, enhancing structural stability. Two fixed brackets 19 support the rotating shaft 20. The rotating belt 14 on the outer wall of the front rotating shaft 13 and the rear rotating shaft 20 rotates in a circular motion as the rotating shaft 13 rotates. The engraver 17 rotates internally with the rotating belt 14. The rotation of the rotating belt 14 causes the engraver 17 to move along a specific trajectory. The laser 18 at the bottom of the engraver 17 emits a high-energy laser beam during the movement of the engraver 17, which is focused on the surface of the board to achieve the engraving effect. When the engraver 17 moves left and right, the hydraulic press 21 is activated, pushing the hydraulic rod 1 23 to slide to the left. The hydraulic rod 24 inside the hydraulic rod 1 23 extends further, causing the fixing plate 2 25 to move to the left or right. This can precisely adjust the position of the fixing seat 8 in the slide groove 9, thereby adjusting the position of the engraver 17 to meet different engraving needs.

[0043] The engraver 17 performs engraving operations on the object, generating dust. The exhaust pipe 202 then starts working, with its soft and elastic rubber disc 203 at the bottom enhancing the dust extraction effect and preventing dust leakage. This ensures that the dust is collected to the maximum extent possible by the exhaust pipe 202. The dust-containing gas is transported upwards along the exhaust pipe 202. The vent pipe 206 on the top right side of the engraver 17 further transports the dust-containing gas collected by the exhaust pipe 202. Due to its reasonable positioning, the gas transmission path is ensured to be smooth. The exhaust port 207 at the bottom of the vent pipe 206 discharges the dust-containing gas. The discharged gas is then guided to a specialized dust removal device for further processing, further separating the dust and gas. The purified gas is then discharged into the atmosphere.
