Description

Technical Field

[0001] This utility model relates to the field of laser engraving machine technology, specifically to a metal engraving device. Background Technology

[0002] In the field of metal processing, with the continuous development of manufacturing, the requirements for metal engraving techniques are becoming increasingly complex and diverse. In modern industrial production, metal engraving is widely used in many industries such as aerospace parts manufacturing, precision component processing for electronic equipment, and personalized customization of jewelry. Different industries have different needs for metal engraving, but they all face common challenges, especially when engraving metal materials of different sizes, where issues such as material cutting and heat dissipation urgently need to be addressed.

[0003] In actual engraving processes, metal materials vary greatly in size and specifications, from small, delicate electronic components to large mechanical structural parts, all requiring precise engraving. However, traditional metal engraving equipment lacks flexibility in its blanking system when handling materials of different sizes. Common blanking devices are often designed for specific size ranges, and when faced with metal materials that are too large or too small, they cannot efficiently remove waste material from the work area after engraving. For example, for small metal materials, the blanking nozzle size is relatively large, which can easily lead to material displacement during engraving, affecting engraving accuracy; while when processing large metal materials, the blanking channel may become clogged due to the large volume of waste material, greatly reducing production efficiency and increasing equipment maintenance costs.

[0004] Meanwhile, the large amount of heat generated during the engraving process is also a significant challenge. Metal engraving typically involves high-speed cutting or high-energy laser irradiation, which causes the metal material to heat up rapidly. The heat dissipation of metal materials varies significantly depending on their size, as their heat capacity and heat dissipation area differ. Small metal materials dissipate heat relatively quickly, but due to their small mass and low heat capacity, they are prone to deformation due to localized overheating, affecting engraving accuracy and surface quality. Large metal materials, while having a large heat capacity, have long heat dissipation paths, causing heat to accumulate internally and be difficult to dissipate. Prolonged high temperatures can lead to thermal distortion of optical components, affecting laser beam quality and thus reducing engraving quality.

[0005] Currently, there is an urgent market demand for metal engraving equipment capable of efficiently handling the blanking of metal materials of different sizes and possessing excellent heat dissipation performance. The shortcomings of traditional engraving equipment in these two aspects severely restrict the improvement of production efficiency and the stability of product quality, failing to meet the demands of modern manufacturing for fast, precise, and high-quality metal engraving processes. Therefore, there is an urgent need for a new type of metal engraving equipment that can effectively solve the problems of blanking and heat dissipation of metal materials of different sizes during the engraving process. It should have a flexibly adjustable blanking structure, be adaptable to various sizes of metal materials, and ensure efficient waste removal and effective heat dissipation during processing.

By setting a rotatable material carrier grid and a matching rotation adjustment mechanism, the angle of the material carrier grid can be flexibly adjusted to adapt to the processing needs of metal materials of different sizes, effectively solving the problem that traditional equipment cannot handle the processing of diverse material sizes. At the same time, the inclined heat dissipation hole design on the material carrier grid can accelerate heat dissipation during the engraving process, avoid material deformation due to overheating, and improve the engraving quality. The displacement device adopts a combination of horizontal and vertical movement mechanisms, and each movement mechanism is equipped with a motor, guide components, drag chains, and slide components, enabling the engraving device to move accurately and smoothly in the horizontal direction, ensuring engraving accuracy and efficiency.

[0037] The beneficial effects of this utility model are as follows:

[0038] (1) This utility model sets a rotatable material grid in the material loading plate group and uses a rotation adjustment mechanism to adjust the angle between the material grid and the horizontal plane. The worm gear and worm wheel cooperation design allows the operator to adjust the angle of the material grid to the ideal state according to the actual needs of different sized processing parts, providing a stable and suitable placement base for various processing parts.

[0061] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0062] Example:

[0063] like Figures 1 to 13As shown, a metal engraving device includes:

[0064] Workbench 1, carving device 2 and displacement device 3;

[0065] The workbench 1 includes a frame 11 and a material plate assembly 12. The material plate assembly 12 is mounted on the frame 11. The material plate assembly 12 includes a mounting frame 121 and several sets of material grids 122. The mounting frame 121 is square-shaped. The material grids 122 are equidistantly arranged along any horizontal side of the mounting frame 121. The equidistant arrangement of the material grids 122 can not only ensure effective support for small metal parts and prevent them from shaking, but also meet the needs of placing large metal plates. At the same time, it facilitates the smooth fall of waste generated during the engraving process through the gaps.

[0066] Furthermore, the two ends of the material carrier grid 122 are rotatably mounted on the mounting bracket 121, allowing the material carrier grid 122 to flexibly adjust its angle while ensuring its stability during rotation. This effectively avoids shaking or jamming and ensures the accuracy of angle adjustment. A rotation adjustment mechanism 13 is installed on each side of the material carrier grid 122. The rotation adjustment mechanism 13 synchronously drives the material carrier grid 122 to rotate, ensuring that the included angle of each material carrier grid 122 remains consistent, avoiding processing errors caused by inconsistent angles. Changing the included angle of the material carrier grid 122 with the horizontal plane helps the metal chips and dust to slide off naturally and dissipate heat. When processing metal materials of different sizes or shapes, adjusting the included angle of the material carrier grid 122 can adapt to the processing requirements of different workpieces. This design not only improves the adaptability and processing accuracy of the equipment but also optimizes heat dissipation and chip removal, enhancing the stability and working efficiency of the equipment. It is particularly suitable for engraving processing of metal materials of multiple sizes and shapes.

[0067] The engraving device 2 is positioned directly above the worktable 1 to ensure that the laser head of the laser engraving machine can accurately engrave the metal workpiece on the worktable below during the engraving process. The engraving device 2 engraves the metal workpiece on the worktable 1 below, and maintains a certain safe distance from the worktable 1. This ensures that debris and other impurities generated during the engraving process will not cause secondary impact on the worktable 1 and the workpiece, and also facilitates equipment debugging and maintenance by the operator.

[0068] The displacement device 3 carries the engraving device 2 to move and switch between the horizontal and vertical directions on the worktable 1. The displacement device 3 includes a horizontal moving mechanism 31 and a vertical moving mechanism 32. The horizontal moving mechanism 31 is mounted on the vertical moving mechanism 32. Through the coordinated work of the horizontal moving mechanism 31 and the vertical moving mechanism 32, the engraving device 2 can cover the entire processing area of ​​the worktable 1, providing the necessary degrees of freedom of movement for the engraving operation. This design fully considers the needs of the equipment in different working scenarios and has the characteristics of high precision, high speed and strong stability. By precisely controlling the movement of the displacement device 3, it can ensure that the engraving device 2 can accurately move to any position on the workpiece to achieve high-precision engraving of complex patterns. In actual work, the displacement device 3 and the engraving device 2 work closely together and precisely adjust the position of the engraving device 2 according to the pre-set engraving program, so that the laser engraving machine 22 can perform precise engraving operations on the surface of metal materials, which greatly improves the engraving efficiency and quality.

[0069] Furthermore, the frame 11 is square-shaped, with a stable overall structure that can evenly distribute the load and ensure the equipment remains balanced during operation. The frame 11 is composed of horizontal frames 111 and vertical frames 112, which are connected to a fixing plate by bolts. The bolts pass through the fixing plate and connect to the horizontal frames 111 and the vertical frames 112. A triangularly arranged bearing plate 113 is installed at the angle where the horizontal frames 111 and the vertical frames 112 meet. The four corners of the material loading plate assembly 12 are placed on the bearing plate 113. This installation method ensures the material loading... The plate assembly 12 is easy to disassemble and maintain, while ensuring installation accuracy and stability. The support plate 113 is used to support the material plate assembly 12 and evenly transfer the weight of the material plate assembly 12 to the frame 11, enhancing the stability of the overall structure. The triangular design of the support plate 113 can effectively disperse stress and prevent the frame 11 from deforming or being damaged due to load concentration at the splicing point. The stable frame 11 structure can reduce vibration and deformation during equipment operation and ensure the processing accuracy of the engraving device 2. This design not only improves the stability and durability of the equipment, but also reduces manufacturing costs and maintenance difficulty.

[0070] Furthermore, the rotation adjustment mechanism 13 includes several sets of worm gears 131, worms 132, bearing seats 133, and drive motors 135. The worm gears 131 are fitted one-to-one with the material-carrying grids 122, ensuring that each material-carrying grid 122 can rotate synchronously, thereby achieving synchronous angle adjustment of the material-carrying grids 122. The worms 132 are fixedly connected to the mounting bracket 121 via the bearing seats 133, ensuring that the worms 132 remain horizontally stable during rotation. The worms 132 are horizontally positioned below the worm gears 131. The threads 134 on the worm gear 132 are respectively engaged with the worm wheels 131. When the worm gear 132 rotates, it drives all the worm wheels 131 to rotate synchronously through the threads 134, thereby realizing the synchronous angle adjustment of the material grid 122. Any end of the worm gear 132 is connected to the drive motor 135 through a coupling. The drive motor 135 is mounted on the mounting bracket 121 through a motor base. The drive motor 135 is preferably a stepper motor or a servo motor, so as to realize the precise control of the rotation angle of the worm gear 132, thereby precisely adjusting the angle of the material grid 122.

[0071] It should be noted that the meshing of the worm gear 131 and the worm 132 has a self-locking characteristic, ensuring that the material grid 122 remains stable after adjustment and will not shift due to external force or vibration.

[0072] The material carrier grid 122 is provided with several sets of heat dissipation holes 1221. The heat dissipation holes 1221 are arranged in an oblique strip shape. The main function of the heat dissipation holes 1221 is to dissipate the heat generated during the laser engraving process and prevent the workpiece from deforming or being damaged due to overheating. The heat dissipation holes 1221 can also help to remove metal chips and dust generated during the engraving process, keep the worktable clean, and avoid chip accumulation that affects the processing accuracy.

[0073] Furthermore, the lateral movement mechanism 31 includes a crossbeam 310, a lateral guide group 311, a lateral drag chain group 312, a lateral movement module 313, and a first connecting plate 314.

[0074] The crossbeam 310 is mounted across the horizontal direction of the workbench 1. Both ends of the crossbeam 310 are respectively connected to the corresponding longitudinal moving mechanism 32. The connection between the two ends of the crossbeam 310 and the longitudinal moving mechanism 32 ensures that the horizontal moving mechanism 31 and the longitudinal moving mechanism 32 work together to realize the multi-directional movement of the engraving device 2.

[0075] The transverse guide group 311 is disposed on the crossbeam 310. The transverse guide group 311 guides the transverse movement of the engraving device 2. The design of the transverse guide group 311 can reduce friction during the movement, improve the movement efficiency, and extend the service life of the equipment.

[0076] The transverse drag chain assembly 312 is laid along the length of the crossbeam 310. The transverse drag chain assembly 312 drags the power cord and is connected to the transverse moving module 313. The transverse drag chain assembly 312 is used to protect the power cord and signal cord, preventing the cord from being pulled or worn during movement. The transverse drag chain assembly 312 can extend and retract with the movement of the engraving device 2, ensuring that the cord is always in a safe state and avoiding equipment failure due to cord problems.

[0077] The lateral movement module 313 is mounted on the crossbeam 310, and the lateral movement module 313 drives the engraving device 2 to move laterally.

[0078] The first connecting plate 314 is installed to connect the engraving device 2 and the transverse moving module 313. The design of the first connecting plate 314 can enhance the connection stability between the engraving device 2 and the transverse moving module 313, and reduce vibration and offset during movement. The design of the transverse guide group 311 and the transverse moving module 313 ensures the accuracy and stability of the engraving device 2 during transverse movement, which not only improves the automation level and processing efficiency of the equipment, but also enhances the stability and durability of the structure.

[0079] Furthermore, the longitudinal moving mechanism 32 is symmetrically arranged in two sets, and each set of the longitudinal moving mechanism 32 includes a longitudinal guide group 321, a longitudinal drag chain group 322, a longitudinal moving module 323 and a second connecting plate 324.

[0080] The longitudinal guide group 321 is disposed on the longitudinal frame 112. The longitudinal guide group 321 guides the longitudinal movement of the carving device 2, ensuring the balance and stability of the carving device 2 during the longitudinal movement process.

[0081] The longitudinal drag chain assembly 322 is laid along the length of the longitudinal frame 112. The longitudinal drag chain assembly 322 drags the power line and is connected to the longitudinal moving module 323. The longitudinal drag chain assembly 322 is used to protect and drag the power line and signal line to ensure that the line is not damaged during the longitudinal movement of the engraving device 2.

[0082] The longitudinal movement module 323 is mounted on the longitudinal frame 112, and the longitudinal movement module 323 drives the engraving device 2 to move longitudinally.

[0083] The second connecting plate 324 is installed to connect the crossbeam 310 and the longitudinal moving module 323, ensuring that the crossbeam 310 can move synchronously with the longitudinal moving module 323.

[0084] It should be noted that the transverse guide group 311 or the longitudinal guide group 321 both include the slide rail group 3111 and the module mounting plate 3112;

[0085] The slide rail assembly 3111 is arranged along the length of the crossbeam 310 or the longitudinal frame 112. The slide rail assembly 3111 can significantly reduce friction during movement and ensure the smoothness and accuracy of the engraving device 2 movement.

[0086] The module mounting plate 3112 is fixedly connected to the slider on the slide rail assembly 3111. The horizontal moving module 313 or the vertical moving module 323 is fixedly mounted on the module mounting plate 3112 to ensure that the moving module moves synchronously with the slide rail assembly 3111. The first connecting plate 314, the second connecting plate 324 and the module mounting plate 3112 are integrated, which simplifies the structural design, enhances the connection stability, and reduces assembly errors. The module mounting plate 3112 transmits the power of the horizontal moving module 313 or the vertical moving module 323 to the engraving device 2 to ensure the accuracy, smoothness and stability of the engraving device 2 during horizontal and vertical movement.

[0087] It should be further noted that both the lateral movement module 313 and the longitudinal movement module 323 include a moving motor 3131, an active synchronous pulley 3132, a driven synchronous pulley 3133, and a synchronous belt 3134.

[0088] The mobile motor 3131 is horizontally mounted on the module mounting plate 3112. The mobile motor 3131 is the power source of the horizontal moving module 313 or the vertical moving module 323, and drives the active synchronous pulley 3132 to rotate through the motor shaft.

[0089] The active synchronous pulley 3132 is sleeved on the motor shaft of the mobile motor 3131, and transmits the rotational power of the motor to the synchronous belt 3134.

[0090] The driven synchronous pulley 3133 is symmetrically arranged below the driving synchronous pulley 3132 to support and guide the movement of the synchronous belt 3134. The driven synchronous pulley 3133 is rotatably mounted on the module mounting plate 3112, and the rolling parts 3135 on both sides of the driven synchronous pulley 3133 are rotatably engaged with the moving grooves 000 on the crossbeam 310 or the longitudinal frame 112 to ensure that the driven synchronous pulley 3133 remains stable during movement. The design of the rolling parts 3135 can reduce the friction between the driven synchronous pulley 3133 and the moving grooves 000 and improve the transmission efficiency.

[0091] The synchronous belt 3134 is arranged in a triangular shape to improve the stability and efficiency of the transmission. The synchronous belt 3134 is wound around the driving synchronous pulley 3132 and the driven synchronous pulley 3133. The synchronous belt 3134 is meshed with the driving synchronous pulley 3132 and the driven synchronous pulley 3133 to ensure the synchronicity of power transmission and avoid slippage or jumping.

[0092] In addition, each of the crossbeams 310 or longitudinal frames 112 is equipped with a touch switch 315. The touch switch 315 is located at one end of the crossbeam 310 or longitudinal frame 112. When the touch switch 315 touches the slider on the corresponding slide rail group 3111, it sends a signal to control the moving motor 3131 to reverse. Through the coordinated work of the touch switch 315 and the moving motor 3131, the equipment can achieve automated limit protection during operation. When the slider approaches the limit position of the crossbeam 310 or longitudinal frame 112, the touch switch is triggered in time to control the moving motor to reverse, ensuring that the equipment operation is always within a safe and controllable range, providing a strong guarantee for the efficient and stable operation of metal engraving.

[0093] In addition, limit blocks are provided at both ends of the moving groove 000 to prevent the driven synchronous pulley 3133 from continuing to move forward when it reaches the end of the moving groove 000 during continuous operation if the touch switch 315 fails. This prevents a series of serious consequences caused by excessive movement. Through the dual protection mechanism of the limit blocks and the touch switch 315, the safety and stability of the equipment during operation are comprehensively improved, ensuring that metal engraving operations can be carried out continuously, efficiently and reliably.

[0094] It should be further explained that the engraving device 2 includes a housing 21, a laser engraving machine 22, and a cooling fan 23. The laser engraving machine 22 is installed in the housing 21, which is hollow. A dust cover 24 is provided on the top of the housing 21, and the dust cover 24 is bolted to the housing 21. The dust cover 24 has ventilation holes 241 for heat dissipation and air circulation. The housing 21 is bolted to the first connecting plate 314 to ensure the stability of the device and facilitate disassembly and maintenance. A limit hole is provided on the end of the first connecting plate 314 that abuts against the bottom of the laser engraving machine 22. The laser head of the laser engraving machine 22 is inserted through the limiting hole 3141 to accurately position the laser head and ensure engraving accuracy. The cooling fan 23 is located on the top of the laser engraving machine 22. During the engraving operation, the laser engraving machine 22 generates a lot of heat. The cooling fan 23 blows hot air and discharges it through the ventilation hole 3142. At the same time, cold air from the outside is drawn in through the ventilation hole 241 and replenishes the bottom of the laser engraving machine 22, forming a stable and efficient airflow circulation path. This prevents the laser engraving machine 22 from overheating and causing performance degradation or damage, and ensures its long-term stable operation.

[0095] Meanwhile, during the operation of the cooling fan 23, the airflow discharged from the vent 221 can sweep away debris and dust on the surface of the workpiece. During metal engraving, the interaction between the laser and the metal material generates a large amount of debris and dust. If these debris adheres to the surface of the workpiece, it will not only affect the accuracy of the subsequent engraving area and cause the laser energy to be partially blocked, resulting in uneven engraving depth, but may also cause local overheating due to heat accumulation, damaging the workpiece. The airflow discharged from the vent 221 blows away the debris and dust quickly at a suitable wind speed, keeping the processing area clean. This can reduce the surface temperature of the workpiece to a certain extent, assist in heat dissipation, further reduce the risk of thermal deformation, and thus improve the quality and efficiency of metal engraving.

[0096] Working process: First, based on the workpiece size, the drive motor of the rotary adjustment mechanism drives the worm gear and worm wheel to rotate and adjust the angle of the material carrier grid to stably place the workpiece. The metal workpiece is placed on the material carrier grid. Then, the horizontal and vertical moving mechanisms of the displacement device drive the synchronous belt through the moving motor, moving the engraving device on the crossbeam and longitudinal frame, guided by the slide rail, and stopping at the designated position. Subsequently, the laser engraving machine starts, and the laser head is positioned through the limit hole for engraving. At the same time, the cooling fan runs, exhausting heat through the ventilation holes and vents, and the blown air can also blow away debris and dust. During the operation of the displacement device, the slider touches the trigger switch, which will reverse the motor to prevent overtravel. If the trigger switch fails, the limit block can prevent the driven synchronous belt pulley from moving. Multiple protections ensure the safety and stability of the equipment, thereby achieving efficient and precise engraving of metal workpieces.

[0097] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
