Description

Technical Field

[0001] This invention relates to the field of laser engraving technology for wood panels, specifically a laser marking machine suitable for engraving patterns on the surface of wood composite panels. Background Technology

[0002] The patent application with publication number CN218964389U includes an engraving table with Y-axis modules symmetrically arranged on it. An X-axis module is mounted between the Y-axis modules. The X-axis module includes a slider with mounting plates symmetrically arranged on the slider. A drive assembly is mounted on the mounting plate, and the drive assembly is connected to a lifting assembly, which in turn is connected to a laser generator. This device uses an automated method to drive the laser generator to move along the X, Y, and Z axes. When the wood board is changed to a different thickness, the drive assembly drives the lifting assembly to move, thereby moving the laser generator closer to or away from the wood board. After adjusting the distance between the laser generator and the wood board, it is only necessary to drive the laser generator to move along the X and Y axes to complete the laser engraving process on the wood board. This method is accurate and reduces labor intensity.

[0016] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0017] (1) The push mechanism is equipped with a pressure plate assembly, a connecting assembly, a rolling assembly, and a cleaning assembly. Through the synergistic effect of the push mechanism and the pressure plate mechanism, efficient and precise positioning and pressing of the wood composite board is achieved. The two sets of fixed limit rods on the worktable and the U-shaped frame on the pressure plate assembly form a pre-positioning effect. The operator only needs to place the wood board between the two fixed limit rods to complete the rough positioning. When the wood board is pushed towards the laser marking machine and enters the U-shaped frame, its three sides will be in close contact with the two side plates and one long horizontal plate of the U-shaped frame. This three-sided surrounding structure precisely constrains the wood board within the predetermined carving area, ensuring that the initial position of the wood board relative to the laser head is highly consistent each time it is carved. This fundamentally avoids problems such as misalignment, incompleteness, or exceeding the boundary caused by manual placement deviation, greatly improving the accuracy of the carving pattern and the consistency of the product. In terms of clamping, once the wooden board reaches the designated position, the drive motor starts, driving the bidirectional ball screw to rotate, causing the two sliding blocks to move in opposite directions. The sliding blocks press the entire pressure plate assembly downwards through the rotating plate. During this process, the pressure plate itself acts as a large-area pressure distribution plate, which can evenly apply pressure to the entire upper surface of the wooden board, effectively preventing the small displacement of the wooden board caused by local stress or equipment vibration during the engraving process. At the same time, the sliding cooperation between the limiting rod and the fixed rod ensures that the pressure plate can only move vertically up and down, avoiding any lateral deviation, further enhancing the stability of clamping. This stable and reliable clamping mechanism creates an extremely stable working platform for the laser marking machine, enabling the laser beam to always be accurately focused on the preset engraving path, thereby engraving high-quality patterns with clear outlines and sharp details, which is significantly better than the traditional manual pressing or simple clamping method.

[0018] (2) Before processing, that is, before the wood board enters the carving station, the rolling component and cleaning component in the connecting assembly clean the wood board. The external water supply equipment injects water into the water pipe through the connecting water pipe, and forms a fine water mist through the atomizing nozzle, which is evenly sprayed onto the rolling brush below, making its fiber cloth surface wet. When the wood board moves forward, its surface first contacts the wet rolling brush. The rolling brush rises under pressure and rotates accordingly. This action is like giving the wood board a "wet scrub", which can effectively soak and initially remove the surface dust and light impurities. Then, the wood board passes under the cleaning brush. The cleaning brush is pressed against the board surface under the pressure of the second spring, thoroughly scraping away excess water and impurities that have been adhered by water. This pretreatment process ensures that the surface of the wood board to be carved is clean and dust-free, and avoids impurities from carbonizing under the high temperature of the laser and permanently adhering to the surface of the wood board or affecting the carving process. The absorption of laser energy lays a solid foundation for achieving a clean and uniformly colored carving effect. During the carving process, an air channel network is embedded inside the pressure plate directly above the carving area and in the pattern components, and connected to an external air extraction device. This enables immediate extraction at the source of the smoke. After the air extraction device is activated, a negative pressure is formed in the gap between the mounting slot, the C-shaped rod, and the connecting short rod. The smoke generated by laser carving is almost instantly drawn into the third air channel, then through the second and first air channels, and finally discharged through the connecting air pipe. This method greatly reduces the diffusion of smoke, effectively prevents secondary pollution, and ensures the clarity of the carved pattern and the cleanliness of the wood surface. The pushing component pushes the processed wood board out, allowing it to pass through the cleaning brush and rolling brush again for final cleaning of any remaining smoke and debris that may have been generated during the carving process.

[0033] like Figures 1 to 11 As shown, the present invention provides a laser marking machine suitable for carving patterns on the surface of wood composite board, including a pushing mechanism 1, a pressure plate mechanism 2 and a laser marking machine 3 arranged above the pushing mechanism 1, the pressure plate mechanism 2 including a pressure plate assembly 21 arranged above the pushing mechanism 1, a connecting assembly 23 arranged on the side of the pressure plate assembly 21 away from the laser marking machine 3, sliding assemblies 22 respectively arranged on both sides of the pressure plate assembly 21, a bidirectional ball screw 24 arranged between the two sets of sliding assemblies 22, a rolling assembly 25 and a cleaning assembly 26 arranged inside the connecting assembly 23, multiple sets of pattern assemblies 27 arranged on the pressure plate assembly 21, and an air passage assembly 28 arranged inside the pressure plate assembly 21;

[0034] The pressure plate assembly 21 includes a pressure plate 211 disposed above the pushing mechanism 1. Two first connecting blocks 213 are fixedly connected to both sides of the pressure plate 211. A U-shaped frame 212 is fixedly connected to one side below the pressure plate 211. The U-shaped frame 212 consists of a long horizontal plate and two side plates. The long horizontal plate of the U-shaped frame 212 is fixedly connected to the side of the pressure plate 211 near the laser marking machine 3. The two side plates of the U-shaped frame 212 are fixedly connected to both sides of the pressure plate 211, and the side plates are located below the first connecting blocks 213. Limiting rods 214 are fixedly connected to both sides of the pressure plate 211. A sliding groove is provided on the limiting rod 214, and a fixed rod 215 is slidably disposed in the groove on the limiting rod 214. Multiple trapezoidal grooves 216 are provided above 11. The trapezoidal grooves 216 are narrow at the top and wide at the bottom. When the laser beam is vertically or nearly vertically irradiated by the side wall of the trapezoidal groove 216, it will first hit the wider slope at the bottom. After being reflected, the light beam will be directed to the other slope of the opposite side wall instead of returning directly along the original path. After such multiple reflections on the slope, the energy of the laser is continuously attenuated and dispersed. In the end, even if a very small amount of light energy tries to escape from the "narrow top" opening, its energy and direction have become negligible, preventing the laser from being directly reflected back along the original path and hitting the laser galvanometer lens and laser emitter above, thus preventing damage to the optical components.

[0042] The drive assembly 12 includes a motor 121 disposed in the workbench 11. A first rotating wheel 122 is fixedly connected to the output end of the motor 121. A gear 123 is rotatably connected above the workbench 11. A second rotating wheel 124 is fixedly connected to the upper end of the gear 123. A rotating belt 125 is movably disposed on the outer side of the second rotating wheel 124 and the first rotating wheel 122.

[0043] The pushing assembly 13 includes a connecting rod 131 fixedly connected to the upper end of the worktable 11, a limiting rod 132 fixedly connected to one side of the connecting rod 131, a sliding long rod 133 slidably arranged on the connecting rod 131, a long rod groove 135 on the side of the sliding long rod 133 facing the connecting rod 131, the limiting rod 132 slidably arranged in the long rod groove 135, a tooth 134 fixedly connected to the side of the sliding long rod 133 away from the connecting rod 131, a push rod 136 fixedly connected to the end of the sliding long rod 133 near the pressure plate 211, and a gear 123 meshing with the tooth 134.

[0044] The working principle of this invention is as follows: During use, the wooden board is placed between two fixed limiting rods 14 to pre-position the board. The board is pushed towards the laser marking machine 3. When the board passes under the fixed long plate 231, it squeezes the rolling brush 251, causing the rolling brush 251 to move upward. The rolling brush 251 drives the second connecting block 253 to move upward through the fixed short rod 252. The second connecting block 253 squeezes the first spring 254. Finally, the rolling brush 251 is above the board and rotates with the movement of the board. Before this, the external water supply device injects water into the water pipe 235 through the connecting water pipe 236 and then sprays it out through the atomizing nozzle 237, so that the fiber cloth on the surface of the rolling brush 251 is wetted. When the rolling brush 251 rotates with the board, it wets the surface of the board. When the board passes under the cleaning brush 262, the cleaning brush 262 scrapes the surface of the board to wipe away the water and remove impurities from the surface of the board, preventing impurities from affecting the carving quality.

[0045] When the wooden board moves below the pressure plate 211, it is inserted into the U-shaped frame 212, with its upper three sides contacting the U-shaped frame 212. At this point, the position of the wooden board is defined. When the wooden board reaches the engraving position, the drive motor rotates the bidirectional ball screw 24. The bidirectional ball screw 24 moves the sliding plate 223 within the worktable 11 through the threaded hole on the sliding plate 223. The sliding plate 223 moves the sliding block 221, increasing the distance between the two sliding blocks 221. The sliding block 221 then moves the pressure plate 211 downwards via the rotating plate 222. The sliding block 221 presses down on the wooden board, and the sliding block 221 drives the limiting rod 214 to move downward. The limiting rod 214 slides outside the fixed rod 215. The laser marking machine 3 starts and engraves the gap between the mounting slot 271, the C-shaped rod 273, and the connecting short rod 272. While the laser is engraving the wooden board, the air extraction device extracts the gas from the first air passage 282 and the second air passage 283 through the connecting air pipe 281. The second air passage 283 extracts the gas from the third air passage 284, and the third air passage 284 extracts the gas from the mounting slot 271. The gas used can directly draw the fumes and other substances generated during laser marking machine 3 engraving from the source into the third air channel 284, then into the second air channel 283 and the first air channel 282, and finally out through the connecting air pipe 281, preventing the fumes and other substances generated during engraving from falling onto the wooden board and adhering to it, thus affecting the surface quality of the wooden board. After engraving is completed, the drive motor rotates in the opposite direction to move the pressure plate 211 upward, no longer squeezing the wooden board. The motor 121 drives the first rotating wheel 122 to rotate, and the first rotating wheel 122 drives the second rotating wheel 12 through the rotating belt 125. 4. Rotation: The second rotating wheel 124 drives the gear 123 to rotate. The gear 123 meshes with the teeth 134, causing the sliding rod 133 to move. The sliding rod 133 is slidably set on one side of the connecting rod 131. The sliding rod 133 drives the push rod 136 to move towards the pressure plate 211. The push rod 136 pushes the wooden board out from under the pressure plate 211. The push rod 136 pushes the wooden board under the cleaning brush 262 and under the rolling brush 251. The rolling brush 251 and the cleaning brush 262 clean the wooden board, so that the impurities caused by carving are wiped off the wooden board.
