Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser processing, and in particular to a laser marking device with a compact internal structure. Background Technology
[0002] Laser marking equipment is a device that uses a laser beam to make precise marks on the surface of materials. It can create high-quality product markings, such as product serial numbers and QR codes, on the surface of different materials, which facilitates product identification and traceability. It mainly includes CO2 laser marking machines, semiconductor laser marking machines and YAG laser marking machines, and is widely used in industries that require high-precision marking.
[0003] Currently, these marking devices are limited by their internal structure, resulting in a large amount of redundant internal space and consequently an excessively large overall size. The reason for this is that the internal laser is positioned horizontally, parallel to one side of the galvanometer, which increases the horizontal width of the entire device. Furthermore, other components cannot be installed within this space, resulting in wasted and redundant space.
[0004] In view of this, this technical solution proposes a laser marking device with a compact internal structure. It adopts a vertically arranged laser generator and a reflection mechanism that changes the optical path angle, so that the laser can work normally when it is placed in a vertical position. This reduces the horizontal width and does not affect the assembly of other components (such as power supply, main control, computer, etc.), thus greatly improving the compactness of the device. Utility Model Content
[0005] The present invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the main objective of this invention is to provide a laser marking device with a compact internal structure, thereby addressing the problems of excessive unnecessary redundant space and overly large overall size in existing laser marking devices.
[0006] To achieve the above objectives, this utility model provides a laser marking device with a compact internal structure, including internal components disposed within a housing. The internal components include a laser generator vertically positioned inside one side of the housing, and an optical path reflection mechanism connected to the top of the laser generator. A galvanometer is connected to the optical path reflection mechanism on a side perpendicular to the laser generator, and a processing position is located below the galvanometer. The optical path reflection mechanism reflects the upward-emitted laser light from the laser generator to the galvanometer.
[0007] As a further embodiment of this utility model, the optical path reflection mechanism includes an outer housing and a reflector disposed inside the outer housing. The reflector is placed at an angle, and a fixing seat is provided outside the reflector. The reflector is sealed inside the outer housing by a cover plate on one side of the fixing seat.
[0008] As a further embodiment of this invention, the internal components also include a mounting plate disposed on the same side of the galvanometer and the laser generator, and the mounting plate is provided with a main controller and a power supply.
[0009] As a further improvement of this invention, a micro-host is provided on one side of the galvanometer.
[0010] As a further improvement of this invention, the laser generator is provided with an adjustment mechanism on one side for height adjustment.
[0011] As a further embodiment of this utility model, the adjustment mechanism includes a fixed plate connected to the back of the laser generator and various support columns connected to the fixed plate. The top of each support column is connected to the top plate, and the top plate is fixed to the top of the laser generator. The fixed plate is provided with a lead screw connected to the slide.
[0012] As a further embodiment of this invention, the top of the lead screw passes through the top plate and is connected to the fine-tuning knob.
[0013] As a further embodiment of this utility model, the bottom of the outer shell is provided with a bottom frame, and an automatic telescopic fixture structure is provided inside the bottom frame.
[0014] As a further embodiment of this utility model, the automatic telescopic fixture structure includes a fixture carrier plate that is connected to a motor via a connector and runs on a guide rail.
[0015] The beneficial effects of this utility model are as follows: This technical solution places the laser generator vertically inside the housing on one side, with its top connected to the optical path reflection mechanism. This mechanism then reflects the upward-emitted laser horizontally to the vertical galvanometer, which finally projects it onto the processing position below the galvanometer. This completely changes the traditional layout of horizontally placed lasers that occupy horizontal space, significantly reducing the width of the equipment and minimizing internal redundant space. At the same time, the main control unit, power supply, and micro-host are integrated on the mounting plate on the same side of the galvanometer and laser generator, which not only shortens the circuit path and reduces energy consumption but also reduces the overall size.
[0016] This solution significantly improves production efficiency while ensuring optical path accuracy and operational stability, enabling efficient deployment of equipment even in confined spaces, thus solving a long-standing problem in the industry. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see the appendix Figure 1-10 , In this technical solution, the connection structure inside the entire laser marking equipment is designed to save space. The laser generator (20) is placed vertically on one side inside the outer shell (1), so that its height direction is fully utilized. The top of the laser generator (20) is directly connected to the optical path reflection mechanism (21). The optical path reflection mechanism (21) includes an obliquely placed reflector (213), which can stably capture and reflect the upward beam emitted by the laser generator (20). The optical path reflection mechanism (21) is connected to a galvanometer (22) on the side perpendicular to the laser generator (20). The beam is reflected laterally onto the galvanometer (22). Below the galvanometer (22) is the processing position (24), which is used to place the workpiece to be processed. The entire assembly process ensures that after the laser is emitted from the vertical generator, it is turned by the reflection mechanism (21) and then accurately hits the processing position (24) downward through the galvanometer (22). The vertical placement of the laser generator (20) avoids the waste of horizontal space caused by the traditional horizontal layout, greatly reducing the width and overall volume of the device. The useless extra space inside is efficiently compressed, while other components such as the main controller (260), power supply (261) and micro host (23) can still be compactly integrated on the same side without affecting normal operation. The device becomes smaller and easier to deploy.
[0032] Reference Appendix Figure 5 , 6 In a preferred embodiment of this utility model, the optical path reflection mechanism (21) of this solution is provided with a protective outer shell (210) on the outside of the entire mechanism, and inside is a reflector (213) placed at a specific angle.
[0033] Specifically, the reflector (213) is precisely positioned by a special mounting base (212). After the reflector (213) is installed, its side is tightly sealed inside the outer casing (210) by a cover plate (211), forming a sealed protective space. This effectively isolates dust, oil and other contaminants from entering the surface of the reflector (213), preventing laser energy attenuation or optical path deviation due to contamination. The mounting base (212) can reduce vibration, and the reflection angle can remain stable even if the equipment is running continuously in an industrial environment.
[0034] The entire mechanism can also be modularly packaged, with components that can be disassembled and replaced, and can be tightly fitted and installed with the vertical laser generator (20) and galvanometer (22).
[0035] Reference Appendix Figure 9In a preferred embodiment of this invention, the mounting plate (26) is disposed within the internal component (2), on the same side as the galvanometer (22) and the laser generator (20). The main control (260) system and the power supply (261) unit are directly fixed on the mounting plate. The main control (260) and the power supply (261) are arranged adjacent to the laser generator (20) and the galvanometer (22) via the mounting plate (26), which shortens the connection distance of control signals and power lines. All core electronic components are concentrated on one side, avoiding space waste and dispersion. This results in a more compact internal layout and a smaller overall size.
[0036] Reference Appendix Figure 4 In a preferred embodiment of this invention, the micro-host (23) of the laser device is positioned on one side of the galvanometer (22), and the micro-host (23) is installed close to the galvanometer (22), making full use of the unused space next to the galvanometer (22). When assembling the micro-host (23), it can be placed vertically on one side of the galvanometer (22), further making the space more compact.
[0037] Reference Appendix Figure 8 In a preferred embodiment of this utility model, the adjustment mechanism (25) is set on one side of the laser generator (20) for height adjustment, mainly to adapt to the specifications of different fixtures or materials to be processed.
[0038] Reference Appendix Figure 8 In a preferred embodiment of this utility model, the connection structure of the adjustment mechanism (25) of this solution includes a fixed plate (254) directly connected to the back of the laser generator (20), and multiple pillars (250) vertically fixed on the fixed plate (254). The top of the pillars (250) is connected to the top plate (251), and the top plate (251) is simultaneously fixed to the top of the laser generator (20). The fixed plate (254) is provided with a lead screw (253), which is connected to the slide (252) by a thread. The slide (252) can be moved by rotating the lead screw (253), thereby adjusting the overall height of the laser generator (20).
[0039] In actual use, the structure of the support column (250) and the top plate (251) effectively prevents vibration or displacement during equipment operation, ensuring the stability of the laser generator (20). The cooperation between the lead screw (253) and the slide (252) achieves high precision and stability of fine adjustment. Operators can easily optimize the beam starting point and improve the accuracy of the light path reflection to the galvanometer (22), thereby reducing marking deviation and enhancing the equipment's adaptability to different workpiece thicknesses or working environments.
[0040] Reference Appendix Figure 8In a preferred embodiment of this utility model, the top of the lead screw (253) passes through the top plate (251) and is connected to the fine adjustment knob (255). By rotating the fine adjustment knob (255), the lead screw (253) is directly driven to rise and fall, thereby finely adjusting the height of the laser generator (20). The height can be precisely controlled without the aid of external tools.
[0041] Reference Appendix Figure 9 , 10 In a preferred embodiment of this utility model: the bottom of the outer shell (1) of this technical solution is provided with a bottom frame (3), and an automatic telescopic fixture structure (30) is installed inside the bottom frame (3). This structure drives the fixture carrier plate (302) to slide smoothly on the guide rail (303) through the motor (300) driving the connector (301), thereby realizing the automatic telescopic function. After the marking is completed, the fixture carrier plate (302) automatically extends, which makes it convenient for the operator to quickly place or take out the fixture and product. After being placed, it automatically retracts into the marking position, thereby improving the degree of automation and improving the overall efficiency.
[0042] Reference Appendix Figure 10 A preferred embodiment of this utility model: The automatic telescopic fixture structure (30) of this technical solution includes a motor (300) and is directly connected to the fixture carrier plate (302) through a connector (301) (such as a connecting rod or a transmission belt). The fixture carrier plate (302) is mounted on a guide rail (303) and can slide along the guide rail (303).
[0043] In practice, for example, after marking is completed, the motor (300) drives the fixture carrier plate (302) to automatically extend out of the outer shell (1), which makes it convenient for operators to quickly place or remove the fixture and products. After being placed properly, it can automatically retract to its original position and enter the marking position, greatly reducing manual operation time and error rate, and significantly improving production efficiency.
