Description

Technical Field

[0001] This utility model belongs to the field of center console panel processing technology, and more specifically, it relates to a laser engraving device for automotive center console panels. Background Technology

[0002] In the manufacturing process of automotive center console panels, various textures, patterns, brand logos, and markings for buttons and knobs need to be engraved on the surface. Therefore, a laser engraving device for automotive center console panels is required. Existing laser engraving devices for automotive center console panels mainly consist of a laser, an optical focusing system, a motion control system, and a worktable. In use, the laser emits a laser beam, which is focused by the optical focusing system. The motion control system then drives the laser head or worktable to complete the engraving on the surface of the center console panel fixed to the worktable according to a preset trajectory.

[0003] Existing application number CN201621089358.7 discloses a laser engraving machine, relating to the field of engraving technology. This laser engraving machine includes a motion mechanism, a motor drive device electrically connected to the motion mechanism for driving the motion mechanism, a laser engraving component mounted on the motion mechanism, a control box for housing the motion mechanism, and a fixing plate mounted inside the control box for fixing the processing material. The motion mechanism specifically includes: a transverse slide rail for supporting the left-right sliding of the laser engraving component; a longitudinal slide rail for supporting the up-down sliding of the laser engraving component; and a forward sliding rail for supporting the back-and-forth sliding of the laser engraving component. The laser engraving machine provided by this utility model controls the motion mechanism to move in multiple directions via the control plate and fixes the processing material inside the control box, avoiding the defect of unstable clamping of the processing material as it moves with the motion mechanism. It offers high precision, facilitates fine engraving work, and ensures consistent appearance of the finished product.

[0004] Based on the above, the laser in the existing automotive center console laser engraving equipment is a core precision instrument. During equipment installation, debugging, routine maintenance, or accidental collisions, the laser lens is easily damaged and worn due to external impacts. Lens wear or damage will lead to laser energy loss, reduced beam quality, and lens ablation due to localized heat focusing, which will greatly shorten the lifespan of the laser. On the other hand, when the equipment is idle, the traditional open structure is prone to adhering to pollutants such as metal shavings and oil particles floating in the workshop. These impurities are very easy to adhere to the surface of the laser lens and form dust accumulation. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a laser engraving device for automotive center console panels. This addresses the issue that in existing automotive center console panel laser engraving devices, the laser, as a core precision instrument, is highly susceptible to damage and wear due to external impacts during equipment installation, debugging, routine maintenance, or accidental collisions. Lens wear or damage leads to laser energy loss, reduced beam quality, and even lens ablation due to localized heat focusing, significantly shortening the laser's lifespan. Furthermore, when the equipment is idle, the traditional open structure easily attracts pollutants such as metal shavings and oil particles floating in the workshop, which readily adhere to the laser lens surface, forming dust accumulation.

[0006] The purpose and effect of this utility model, a laser engraving device for automotive center console panels, are achieved through the following specific technical means:

[0007] A laser engraving device for automotive center console panels includes a worktable, a transmission frame, a drive mechanism, a motion mechanism, a laser, a laser lens, a housing assembly, and a lens assembly. The transmission frame is slidably connected to the upper part of the worktable; the drive mechanism is mounted on one side of the transmission frame; the motion mechanism is slidably connected inside the transmission frame; the laser is bolted to the front side of the motion mechanism; the laser lens is fixedly mounted on the bottom surface of the laser; the housing assembly is disposed on the outside of the laser; and the lens assembly is disposed on the bottom surface of the laser.

[0008] Furthermore, the housing assembly includes a protective housing and electric push rods. The protective housing is slidably connected to the outside of the laser. Two sets of electric push rods are provided, and the two sets of electric push rods are fixedly installed on the left and right sides of the laser. The bottom ends of the two sets of electric push rods are fixedly installed on the upper part of the protective housing.

[0009] Furthermore, the housing assembly includes: heat dissipation grooves, and multiple sets of heat dissipation grooves are formed around the protective housing.

[0010] Furthermore, the lens assembly includes a drive rack, wherein two sets of drive racks are provided, and the two sets of drive racks are fixedly connected to both sides inside the protective housing.

[0011] Furthermore, the lens assembly also includes: a fixing block, a threaded rod, and a drive gear. The fixing block is provided in two sets, and the two sets of fixing blocks are fixedly installed on both sides of the bottom end face of the laser. The threaded rod is provided in two sets, and the two sets of threaded rods are rotatably connected inside the two sets of fixing blocks respectively. The drive gear is provided in two sets, and the two sets of drive gears are fixedly installed on the top ends of the two sets of threaded rods respectively. The drive gear and the drive rack mesh with each other.

[0012] Furthermore, the lens assembly also includes: guide rails and transmission blocks. The guide rails are provided in two sets, and the two sets of guide rails are fixedly installed on both sides of the bottom end face of the laser. The transmission blocks are provided in two sets, and the two sets of transmission blocks are slidably connected inside the two sets of guide rails. The two sets of transmission blocks are respectively threadedly connected to one end of the two sets of threaded rods.

[0013] Furthermore, the lens assembly also includes: a protective head and a flexible brush. The protective head is provided in two sets, and the two sets of protective heads are respectively fixedly installed at one end of the two sets of transmission blocks. The flexible brush is provided in multiple sets, and the multiple sets of flexible brushes are fixedly installed on the upper part of the two sets of protective heads.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Firstly, this invention features a housing assembly, consisting of a protective housing and an electric push rod on the outside of the laser. When the laser is idle, the electric push rod moves the protective housing downwards to cover the bottom of the laser, providing all-around protection for the laser lens. This prevents internal optical components from shifting or the lens from being damaged due to external impacts during equipment installation, debugging, routine maintenance, or accidental collisions, significantly reducing maintenance costs and alleviating production burden. When the laser is in operation, the electric push rod pulls the protective housing upwards, allowing the laser beam to be emitted unobstructed for engraving operations. Simultaneously, multiple sets of heat dissipation grooves around the protective housing effectively dissipate internal heat during laser operation, ensuring stable laser operation.

[0016] Secondly, this invention features a lens assembly. A protective housing drives a rack and pinion mechanism, which meshes with a gear to rotate a threaded rod, thereby causing a transmission block to slide within a guide rail. As the transmission block moves, the protective head and its flexible brush wipe the surface of the laser lens, effectively removing dust and ensuring the lens's optical performance. When the protective housing moves downwards to protect the laser lens, the two sets of protective heads move relative to each other, forming a barrier to prevent external dust from entering and providing additional physical protection. When the protective housing moves upwards, the two sets of protective heads move in opposite directions to expose the laser lens, ensuring it can emit a laser beam for precise engraving.

[0017] This invention has the advantages of convenient maintenance, safety protection, and reduced dust accumulation. It effectively solves the problems of lasers being easily damaged by impacts and high maintenance costs, and avoids the problem of dust accumulation on the lens surface affecting its use. It significantly improves the stability and reliability of the laser engraving device for automotive center console panels. Attached Figure Description

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example 1

[0027] As attached Figure 1 To be continued Figure 6 As shown:

[0028] This utility model provides a laser engraving device for automotive center console panels, including a worktable 1, a transmission frame 2, a drive mechanism 3, a motion mechanism 4, a laser 5, a laser lens 501, and a housing assembly. The transmission frame 2 is slidably connected to the upper part of the worktable 1; the drive mechanism 3 is installed on one side of the transmission frame 2; the motion mechanism 4 is slidably connected inside the transmission frame 2; the laser 5 is bolted to the front side of the motion mechanism 4; the laser lens 501 is fixedly installed on the bottom surface of the laser 5; and the housing assembly is located on the outside of the laser 5.

[0029] The housing assembly includes a protective housing 6 and an electric push rod 601. The protective housing 6 is slidably connected to the outside of the laser 5. Two sets of electric push rods 601 are provided. The two sets of electric push rods 601 are fixedly installed on the left and right sides of the laser 5, and the bottom ends of the two sets of electric push rods 601 are fixedly installed on the upper part of the protective housing 6.

[0030] The housing assembly includes a heat dissipation groove 602, which has multiple sets and is located around the protective housing 6.

[0031] The specific usage and function of this embodiment are as follows:

[0032] When the laser 5 is idle and not in operation, the two sets of electric push rods 601 are activated simultaneously, causing the protective housing 6 to slide downwards until it completely covers the bottom area of ​​the laser 5. This protects the laser lens 501 and effectively avoids the risk of damage to the laser lens 501 caused by external collisions or mechanical friction.

[0033] When the laser engraving operation begins, the two sets of electric push rods 601 quickly reverse direction, lifting the protective housing 6 upwards to the outside of the laser 5, exposing the laser lens 501. At this time, the laser 5 can emit a laser beam without obstruction, and in conjunction with the coordinated operation of the motion mechanism 4 and the drive mechanism 3, it can perform efficient and precise engraving operations on the central control panel. The multiple sets of heat dissipation grooves 602 evenly distributed around the protective housing 6 can form an efficient air convection channel during the continuous operation of the laser 5, effectively dissipating the heat generated inside. Example 2

[0034] Based on Example 1, such as Figures 1 to 6 As shown, it also includes a lens assembly, which is disposed on the bottom surface of the laser 5.

[0035] The lens assembly includes a drive rack 603, which is provided in two sets and is fixedly connected to both sides inside the protective housing 6.

[0036] The lens assembly also includes: a fixing block 503, a threaded rod 5031, and a drive gear 5032. Two sets of fixing blocks 503 are provided, and the two sets of fixing blocks 503 are fixedly installed on both sides of the bottom end face of the laser 5. Two sets of threaded rods 5031 are provided, and the two sets of threaded rods 5031 are rotatably connected inside the two sets of fixing blocks 503 respectively. Two sets of drive gears 5032 are provided, and the two sets of drive gears 5032 are fixedly installed on the top of the two sets of threaded rods 5031 respectively. The drive gears 5032 and the drive rack 603 mesh with each other.

[0037] The lens assembly also includes: a guide rail 502 and a transmission block 5021. Two sets of guide rails 502 are provided, and the two sets of guide rails 502 are fixedly installed on both sides of the bottom end face of the laser 5. Two sets of transmission blocks 5021 are provided, and the two sets of transmission blocks 5021 are slidably connected inside the two sets of guide rails 502 respectively. The two sets of transmission blocks 5021 are respectively threaded to one end of two sets of threaded rods 5031.

[0038] The lens assembly also includes: a protective head 5022 and a flexible brush 5023. The protective head 5022 is provided in two sets, and the two sets of protective heads 5022 are respectively fixedly installed at one end of the two sets of transmission blocks 5021. The flexible brush 5023 is provided in multiple sets, and the multiple sets of flexible brushes 5023 are fixedly installed on the upper part of the two sets of protective heads 5022.

[0039] The specific usage and function of this embodiment are as follows:

[0040] When the two sets of electric actuators 601 drive the protective housing 6 to move, the protective housing 6 drives the drive rack 603, which is fixedly connected to it, to move synchronously. The movement of the drive rack 603 drives the drive gear 5032 to rotate. The rotation of the drive gear 5032 further drives the threaded rod 5031 to rotate smoothly within the fixed block 503. Since the transmission block 5021 is connected to the threaded rod 5031 by threads, the rotation of the threaded rod 5031 is converted into the sliding of the transmission block 5021 within the guide rail 502 through the threaded structure. The guide rail 502 ensures that the transmission block 5021 can move accurately along the predetermined trajectory.

[0041] As the transmission block 5021 moves, the protective head 5022, which is fixedly connected to the transmission block 5021, also moves. Multiple sets of flexible brushes 5023 installed on the protective head 5022 wipe the surface of the laser lens 501, effectively removing the floating dust attached to its surface and ensuring that the optical performance of the laser lens 501 is not affected.

[0042] When the protective housing 6 moves downward to protect the laser lens 501, the two sets of protective heads 5022 move relative to each other and gradually approach each other, forming a barrier in front of the laser lens 501. This not only prevents external dust from entering and reduces its contamination of the laser lens 501, but also provides additional physical protection for the laser lens 501, reducing its risk of accidental impact.

[0043] When the protective housing 6 moves upward to expose the laser lens 501 for laser engraving, the two sets of protective heads 5022 move in opposite directions and gradually separate, thus fully exposing the laser lens 501 so that it can emit a laser beam normally and accurately engrave the car's center console panel.
