Description

Technical Field

[0001] The utility model relates to the technical field of advertisement production, in particular to a laser engraving device for advertisement production. Background Technique

[0002] When the laser engraving technology is applied in the field of advertisement production, it is necessary to etch the surface of wooden, metal or plastic plates through a high-energy laser beam to form corresponding characters or graphics, so as to achieve the effect of advertisement publicity.

[0003] After retrieval, the patent with the patent publication number of CN116551202B discloses a laser engraving device for advertisement production. Although the device can engrave the surface of the workpiece inside the engraving table through the laser head at the top during use, when the device is in use, the laser beam is focused on an extremely small light spot to generate a high energy density, and then the surface treatment operation of the material is carried out. In this process, the brightness of the laser is very high, far exceeding the brightness of the sun and the arc. Directly irradiating the eyes will cause serious damage. Even if the weak laser directly irradiates the naked eye, it will feel very dazzling, and the high-power laser may cause temporary blindness of the eyes or even permanent damage. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a laser engraving device for advertisement production, which solves the problems put forward in the background technique.

[0005] The solution of the utility model to the above technical problems is as follows:

[0006] A laser engraving device for advertisement production, including a chassis, a longitudinal moving mechanism is installed on the chassis, a tray is installed on the longitudinal moving mechanism, and a transverse moving mechanism is installed above the tray on the chassis;

[0007] The tray is used to place the plate to be processed, and a light-shielding module is placed around the plate to be processed on the tray. The light-shielding module is provided with a base, a limiting groove is opened on the base, a magnet is inlaid on one side of the base located in the limiting groove, a fixing seat is installed in the limiting groove of the base in a limited way, and a light-shielding mirror is installed on the fixing seat.

[0008] On the basis of the above technical solutions, the utility model can be further improved as follows.

[0009] Further, after the fixing seat is inserted and installed in the limiting groove, it is fixed by the adsorption of the magnet.

[0010] The beneficial effect of adopting the above further scheme is:

[0011] The fixed seat is installed in the limit slot by means of plugging, which is simple to operate, eliminating the need for complex tools or fasteners. Only manual plugging is required to complete the preliminary installation. After plugging, the magnet adsorption further stabilizes the position of the fixed seat, eliminating the need for additional tightening operations, greatly simplifying the installation steps and improving the assembly efficiency. The plugging structure provides the preliminary positioning and fixing functions, while the magnet adsorption provides additional stability, preventing the fixed seat from loosening or displacing during use, ensuring the stability and reliability of the light-shielding module during use. Due to the use of magnetic adsorption for fixation, the disassembly process is also very convenient. Just overcome the adsorption force of the magnet to easily remove the fixed seat, facilitating cleaning, maintenance or component replacement.

[0012] Further, the fixed seat is provided with a plugging block, and the light-shielding mirror is provided with a groove. The light-shielding mirror is installed on the fixed seat in a limited manner through the cooperation of the groove and the plugging block.

[0013] The beneficial effects of adopting the above further solution are:

[0014] The design of the plugging block and the groove enables the light-shielding mirror to be accurately aligned and installed on the fixed seat. The operator only needs to align the groove with the plugging block and easily push it in to complete the installation, without the need for complex tools or additional fasteners. This design reduces the steps in the installation process, making the installation of the light-shielding mirror simple and fast, significantly improving the work efficiency. The cooperation of the plugging block and the groove enables the light-shielding mirror to be firmly installed in a limited manner on the fixed seat, not easily displaced or loosened, ensuring the stability of the light-shielding module during use. In addition to the preliminary plugging fixation, the groove provides an additional limiting function, further enhancing the stability of the light-shielding mirror and ensuring that it is not affected by external forces during the laser engraving operation.

[0015] Further, the lateral movement mechanism is provided with a first motor, the output end of the first motor is installed with a first threaded rod, a first slider is installed on the first threaded rod, a laser head is installed on the first slider, and first limiting rods are arranged on both sides of the first threaded rod of the lateral movement mechanism. The first slider slides laterally through the cooperation of the first threaded rod and the first limiting rods.

[0016] The beneficial effects of adopting the above further solution are:

[0017] The first threaded rod is connected to the first motor. The motor drives the threaded rod to rotate, driving the first slider to move smoothly along the horizontal direction (X-axis). The design of the threaded rod can accurately control the moving position of the slider, achieving high-precision positioning of the laser head in the horizontal direction. The first limiting rod provides guiding support on both sides of the first threaded rod, ensuring that the slider remains stable during movement without wobbling or deviation, further improving the movement precision of the laser head. Since the first slider moves under the dual constraints of the first threaded rod and the limiting rod, its anti-vibration performance is greatly enhanced. During the laser engraving process, even if the device experiences slight vibrations, the slider can still move smoothly, ensuring the precision and quality of engraving. The design of the threaded rod ensures that the moving speed of the slider is uniform and controllable, enabling the laser head to move along the X-axis at a stable speed and avoiding problems such as reduced precision or scratches caused by uneven speed during the engraving process.

[0018] Furthermore, the longitudinal moving mechanism is provided with a second motor. The output end of the second motor is equipped with a second threaded rod. The longitudinal moving mechanism is provided with second limiting rods on both sides of the second threaded rod. A second slider is installed on the second limiting rod and the second threaded rod, and the second slider slides longitudinally through the mutual cooperation of the second limiting rod and the second threaded rod.

[0019] The beneficial effects of adopting the above further solution are:

[0020] The second motor drives the second threaded rod to rotate, driving the second slider threadedly connected thereto to move along the longitudinal direction (Y-axis). The rotational motion of the threaded rod is converted into the linear motion of the slider, achieving high-precision positioning of the slider in the Y-axis direction and ensuring the precise movement of the pallet during the processing. The second limiting rods are arranged on both sides of the threaded rod, providing additional guiding and support to prevent the slider from wobbling or deviating during movement, further ensuring the stability and precision of the slider movement. The slider moves through the cooperation of the threaded rod and the limiting rod, effectively reducing vibrations and deviations during movement and ensuring the smoothness of the longitudinal movement. This is particularly important for engraving operations that require high precision and can significantly improve the processing quality. The threaded rod drive design enables the slider to move at a uniform and controllable speed longitudinally, avoiding the negative impact of speed fluctuations on the processing effect.

[0021] Furthermore, through holes are formed through the pallet, threaded holes are formed on the second slider, and the pallet is installed on the second slider through the through holes, threaded holes and bolts.

[0022] The beneficial effects of adopting the above further solution are:

[0023] The pallet is fixed on the second slider through the cooperation of the fixing holes and threaded holes with bolts, ensuring a firm and reliable connection between the pallet and the slider, and enabling it to effectively resist the vibration and external forces generated during the processing. The cooperation between the threaded holes and the bolts provides a strong clamping force, preventing the pallet from loosening or shifting during use and maintaining its stability during the processing.

[0024] Furthermore, a magnet or a counterweight is embedded at the bottom end of the base. The base is fixed on the pallet by magnetic adsorption or placed on the pallet by the counterweight, and the number of the light-shielding modules is set according to the area of the plate to be processed.

[0025] The beneficial effects of adopting the above further scheme are as follows:

[0026] Through magnetic adsorption fixation, the light-shielding module can be quickly and firmly installed on the pallet. The magnetic fixation method is not only easy to install but also allows for quick adjustment or movement of the light-shielding module to adapt to different working requirements. The design of the counterweight enables the light-shielding module to be fixed on the pallet by simple gravity without relying on magnetic materials. For occasions where magnets cannot be used, the counterweight provides another effective fixation method, increasing the adaptability of the design. The designs of the magnet and the counterweight make the installation and disassembly of the light-shielding module rapid and simple, without the need for complex tools or operations. This greatly saves the time for equipment maintenance and adjustment and improves the operation efficiency. The number and position of the light-shielding modules can be adjusted according to the area of the plate to be processed, enabling the equipment to adapt to the requirements of plates of different specifications. The operator can flexibly configure the light-shielding modules according to the actual situation to ensure the light-shielding effect during the laser engraving process. The number of the light-shielding modules can be adjusted according to the area of the plate to ensure that all four sides of the plate are fully shielded from light during the laser engraving process. It effectively blocks the leakage of the laser, protects the operator from laser damage, and reduces light pollution.

[0027] The present utility model provides a laser engraving device for advertising production. It has the following beneficial effects:

[0028] The longitudinal movement mechanism and the transverse movement mechanism drive the threaded rod through the motor to ensure the precise positioning of the laser head in the XY plane. This design significantly reduces the error during the engraving process and improves the engraving accuracy. With the assistance of the limiting rod, the slider moves more smoothly during the movement, effectively avoiding the accuracy problems caused by vibration during the engraving process.

[0029] The light-shielding module is fixed on the pallet by magnets or counterweights and can be flexibly set according to the size of the plate to be processed. The light-shielding module forms a closed or semi-closed protection area around the plate to prevent laser leakage and protect the safety of the operator's eyes and the surrounding environment. The light-shielding module consists of a base, a fixing seat and a light-shielding mirror, and the components are installed by plugging and magnetic attraction, which is simple and convenient to operate and easy to disassemble and adjust. This design not only improves the flexibility of operation but also enhances the safety of the device.

[0030] The number of light-shielding modules can be adjusted according to the size of the plate to be processed, with strong adaptability. This feature enables the device to process plates of different sizes and shapes and has a wide range of application scenarios. The base of the light-shielding module is fixed by magnetic adsorption, with quick installation and flexible position, facilitating the adjustment of the position and number of the light-shielding modules as needed. Through the effective design of the light-shielding module, the light pollution generated during the laser engraving process is significantly reduced, improving the quality of the working environment, reducing light interference, and enhancing the safety and comfort of the workplace.

A second slider 301 is installed on the second limit rod 303 and the second threaded rod 304. The second slider 301 slides longitudinally through the mutual cooperation of the second limit rod 303 and the second threaded rod 304. The second motor 302 drives the second threaded rod 304 to rotate, driving the second slider 301 connected to it in a threaded manner to move longitudinally (Y-axis). The rotational movement of the threaded rod is converted into the linear movement of the slider, achieving high-precision positioning of the slider in the Y-axis direction and ensuring the precise movement of the pallet 2 during the processing. The second limit rods 303 are arranged on both sides of the threaded rod, providing additional guidance and support to prevent the slider from wobbling or shifting during movement, further ensuring the stability and precision of the slider movement. The slider moves through the cooperation of the threaded rod and the limit rod, effectively reducing vibration and deviation during movement and ensuring the smoothness of longitudinal movement. This is particularly important for engraving operations that require high precision and can significantly improve the processing quality. The threaded rod drive design enables the slider to move at a uniform and controllable speed during longitudinal movement, avoiding the negative impact of speed fluctuations on the processing effect. A pallet 2 is installed on the longitudinal movement mechanism 3. Fixing holes 201 are drilled through the pallet 2. Threaded holes are provided on the second slider 301. The pallet 2 is installed on the second slider 301 through the fixing holes 201, threaded holes and bolts. The pallet 2 is fixed to the second slider 301 through the cooperation of the fixing holes 201 and threaded holes with bolts, ensuring a firm and reliable connection between the pallet 2 and the slider and being able to effectively resist the vibration and external forces generated during the processing.

The motor drives the threaded rod to rotate, driving the first slider 102 to move smoothly transversely (X-axis). The design of the threaded rod can precisely control the movement position of the slider, achieving high-precision positioning of the laser head 105 in the transverse direction. The first limit rods 103 provide guiding support on both sides of the first threaded rod 101 to ensure that the slider remains stable during movement without wobbling or shifting, further improving the movement precision of the laser head 105.Since the first slider 102 moves under the dual constraints of the first threaded rod 101 and the limiting rod, its anti-vibration performance is greatly enhanced. During the laser engraving process, even if the equipment vibrates slightly, the slider can still move smoothly, ensuring the engraving accuracy and quality.

[0044] Embodiment 2

[0045] To block the strong light generated during processing, exemplarily, such as Figures 1 to 5As shown in the figure, the present invention further includes: a pallet 2 for placing the to-be-processed sheet material. Around the to-be-processed sheet material on the pallet 2, a light-shielding module 4 is placed. The light-shielding module 4 is provided with a base 404, and a magnet 403 or a counterweight is embedded at the bottom end of the base 404.

The fixing method of the magnet 403 is not only simple to install, but also can quickly adjust or move the light-shielding module 4 to adapt to different working requirements. The design of the counterweight enables the light-shielding module 4 to be fixed on the pallet 2 by simple gravity without relying on magnetic materials. For occasions where the magnet 403 cannot be used, the counterweight provides another effective fixing method, increasing the adaptability of the design.

This greatly saves the time for equipment maintenance and adjustment and improves the operation efficiency. The number and position of the light-shielding modules 4 can be adjusted according to the area of the to-be-processed sheet material, enabling the equipment to adapt to the requirements of different specifications of sheet materials. The operator can flexibly configure the light-shielding modules 4 according to the actual situation to ensure the light-shielding effect during the laser engraving process.

A limiting groove 405 is opened on the base 404, and a magnet 403 is embedded on one side of the base 404 located in the limiting groove 405. A fixing seat 406 is installed in the limiting groove 405 of the base 404 in a limited way. After the fixing seat 406 is inserted and installed in the limiting groove 405, it is adsorbed and fixed by the magnet 403. The fixing seat 406 is installed in the limiting groove 405 in a plug-in form, with convenient operation, without the need for complicated tools or fasteners, and only manual plugging is required to complete the preliminary installation. After the plugging is completed, the adsorption effect of the magnet 403 further stabilizes the position of the fixing seat 406, without the need for additional tightening operations, greatly simplifying the installation steps and improving the assembly efficiency. The plug-in structure provides a preliminary positioning and fixing function, while the magnet 403 adsorption provides additional stability, preventing the fixing seat 406 from loosening or displacing during use, ensuring the stability and reliability of the light-shielding module 4 during use. Due to the use of magnetic adsorption for fixing, the disassembly process is also extremely convenient.

In addition to the initial insertion and fixation, the groove also provides an additional limiting function, further enhancing the stability of the light-shielding mirror 401 and ensuring that it is not affected by external forces during the laser engraving operation.

[0046] Working principle:

[0047] The second motor 302 drives the second threaded rod 304 to rotate, driving the second slider 301 threadedly connected thereto to move along the Y-axis direction. The second limiting rod 303 plays a guiding and limiting role to ensure that the second slider 301 moves smoothly along a fixed trajectory. The pallet 2 is connected to the second slider 301 through the fixing hole 201 and bolts. As the second slider 301 moves, the pallet 2 and the sheet material thereon move in the Y-axis direction.

[0048] The first motor 104 drives the first threaded rod 101 to rotate, driving the first slider 102 threadedly connected thereto to move along the X-axis direction. The first limiting rod 103 also plays a guiding and limiting role to ensure that the first slider 102 moves smoothly along a fixed trajectory. The laser head 105 is fixed on the first slider 102. As the first slider 102 moves, the laser head 105 moves in the X-axis direction.

[0049] By controlling the movements of the second motor 302 and the first motor 104, the coordinated movements of the pallet 2 and the laser head 105 can be achieved, and further, the laser head 105 can be accurately positioned at any position in the XY plane. The laser head 105 moves along a predetermined path on the XY plane to perform laser engraving on the sheet material.

[0050] The base 404 of the light-shielding module 4 is adsorbed on the pallet 2 by the magnet 403 or fixed by a counterweight, and its position can be adjusted according to the size of the sheet material. According to the shape and size of the sheet material, the number of light-shielding modules 4 can be flexibly increased or decreased to ensure that the periphery of the sheet material is covered by the light-shielding modules 4 during the laser engraving process.

[0051] The light-shielding mirror 401 is installed on the fixed seat 406 of the light-shielding module 4. These light-shielding mirrors 401 form a closed or semi-closed area to block the laser that may leak during the laser engraving process. The magnetic adsorption type fixation and the insertion block 402 design make the installation and disassembly of the light-shielding module 4 very convenient, and the operator can quickly adjust the position of the light-shielding module 4 to adapt to different specifications of sheet materials.
