Description

Technical Field

[0001] This utility model relates to the field of laser engraving equipment technology, and in particular to an electric door-opening ultraviolet light internal engraving laser machine. Background Technology

[0002] Desktop laser marking machines are increasingly popular due to their high precision, high speed, small size, minimal pattern deformation, ease of operation, and ability to engrave on most commonly used materials. Common engraving light sources include violet, blue, and red light. However, existing desktop high-speed dual laser marking machines have the following drawbacks:

[0003] 1. Red and blue photosensitive laser marking machines can only engrave on a flat surface and cannot engrave internally.

[0004] 2. The light source of the laser marking machine should not be looked at directly, as it is irritating to the human eyes. Traditional light shields are manually opened, which is inefficient and unsafe.

[0005] 3. Traditional desktop laser marking machines move the main unit directly along the Z-axis, resulting in a large load and difficulty in ensuring accuracy. Utility Model Content

[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of an electrically operated ultraviolet laser engraving machine with internal carving features, in conjunction with the accompanying drawings and embodiments, provides a more comprehensive understanding. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit its scope.

[0045] Please refer to Figures 1-7A type of electrically operated ultraviolet laser engraving machine with an internal engraving mechanism, comprising:

[0046] Base assembly 100;

[0047] The first Z-axis moving mechanism 200 includes a first stepper motor 210, a first lead screw 220 and a first lead screw 220 nut. The first stepper motor 210 drives the first lead screw 220 to rotate, causing the first lead screw 220 nut to move along the first lead screw 220.

[0048] The second Z-axis moving mechanism 300 includes a second stepper motor 310, a second lead screw 320, and a nut for the second lead screw 320. The second stepper motor 310 drives the second lead screw 320 to rotate, causing the nut for the second lead screw 320 to move along the second lead screw 320.

[0049] A vertical mounting base 400 is fixed to one end of the X-axis of the base assembly 100, so that the other end of the base assembly 100 along the X-axis forms a working area 410. A first Z-axis moving mechanism 200 and a second Z-axis moving mechanism 300 are installed at intervals along the X-axis in the vertical mounting base 400. The first Z-axis moving mechanism 200 is set close to the working area 410. A Z-axis auxiliary frame 421 is provided at each end of the second lead screw along the Y-axis. The Z-axis auxiliary frame 421 is provided with a Z-axis slide groove 422. A first exhaust fan 430 is provided at the end of the vertical mounting base 400 facing the working area 410, and a second exhaust fan 440 is provided at the end of the vertical mounting base 400 away from the working area 410. The vertical mounting base 400 has an exhaust space 450 that connects the first exhaust fan 430 and the second exhaust fan 440.

[0050] The host module 500 includes a host housing 510, and a violet laser 520, a field lens 530 and a heat dissipation module configured in the host housing 510. The host housing 510 is fixedly configured on the top of the vertical mounting base 400 and protrudes into the working area 410.

[0051] The engraving platform 600 is connected to the first lead screw 220 nut through the first connecting frame 240. Each end of the Y-axis of the first connecting frame 240 is connected to an auxiliary slider 260. The vertical mounting base 400 is provided with a Z-axis auxiliary guide rail 250 at each end of the Y-axis of the first lead screw 220. Each auxiliary slider 260 slides in cooperation with a Z-axis auxiliary guide rail 250.

[0052] The door cover 700 is connected to the second connecting bracket 340 via the second lead screw 320 nut. The vertical mounting base 400 has mounting grooves at both ends of the Y-axis that open into the working area 410. The door cover 700 is connected to the second connecting bracket 340 via the mounting grooves. The door cover 700 is connected to the sliding wheel 710, which slides in cooperation with the Z-axis sliding groove 422. When the door cover 700 descends and contacts the base assembly 100, it closes the working area 410.

[0053] The main unit module 500 uses a violet laser 520 for internal engraving. The first Z-axis moving mechanism 200 drives the engraving platform 600 to rise and fall, thus cooperating with the main unit module 500 for three-dimensional laser internal engraving. Z-axis movement is achieved by adjusting the distance between the engraving platform 600 and the main unit module 500 through the lifting and lowering of the engraving platform 600, resulting in low lifting load, minimal deviation, and high precision. The second Z-axis moving mechanism 300 drives the door cover 700 to rise and fall, eliminating the need for manual lifting and improving work efficiency and safety. The first Z-axis moving mechanism 200 is guided by the Z-axis auxiliary guide rail 250 and auxiliary slider 260, ensuring strong stability and high load-bearing torque. The second Z-axis moving mechanism 300 is guided by the Z-axis auxiliary frame 421 and sliding wheels 710, ensuring stable and smooth sliding. An exhaust mechanism is also installed inside the vertical mounting base 400. The first exhaust fan 430 discharges the gas and dust generated in the working area 410 through the exhaust space 450 and the second exhaust fan 440, thereby preventing dust generated during laser cutting from interfering with laser operation.

[0054] Please refer to Figure 4 The base assembly 100 has a receiving cavity 110 below the vertical mounting base 400, and the first stepper motor 210 and the second stepper motor 310 are disposed in the receiving cavity 110. The stepper motors are disposed in the receiving cavity 110 so that the exhaust space 450 is large enough to ensure the exhaust effect.

[0055] Please refer to Figure 2 and Figure 4 The base assembly 100 has a perforated heat dissipation plate 120 at the bottom corresponding to the receiving cavity 110 to ensure heat dissipation of the stepper motor.

[0056] Please refer to Figure 7 The heat dissipation module includes a heat sink 541 and a cooling fan 542. One side of the heat sink 541 is in contact with the ultraviolet laser 520. The main unit chassis 510 is provided with heat dissipation holes 543 that communicate with the cooling fan 542. The heat sink 541 is generally provided with several heat dissipation fins and is generally made of aluminum or aluminum alloy.

[0057] Please refer to Figures 3-5 The vertical mounting base 400 has several Z-axis frames 420, and the middle of the Z-axis frames 420 has connecting holes. The main unit housing 510 is fixedly connected to the vertical mounting base 400 through the connecting holes. That is, the main unit housing 510 and the vertical mounting base 400 are connected as one unit by connecting studs and connecting holes.

[0058] Please refer to Figures 3-5 Two Z-axis skeletons 420 form a Z-axis auxiliary skeleton 421. In particular, the Z-axis auxiliary skeleton 421 has Z-axis grooves 422 on both sides along the X-axis direction, and the sliding wheels 710 clamp the Z-axis auxiliary skeleton 421 from the front and back.

[0059] Please refer to Figure 1 and Figure 2 The vertical mounting base 400 has at least one clearance hole 460 on the side facing the work area 410, and the engraving platform 600 is fixedly connected to the first connecting frame 240 through the clearance hole 460. Preferably, there are two clearance holes 460 spaced apart. It can be understood that the Z-direction distance of the clearance holes 460 is greater than or equal to the lifting stroke of the engraving platform 600.

[0060] Please refer to Figure 1 and Figure 2 The vertical mounting base 400 has a Z-axis scale 470 on the side facing the work area 410. The Z-axis scale 470 facilitates the horizontal adjustment, initial height adjustment, and observation during operation of the engraving platform 600.

[0061] Please refer to Figures 3-5 The distance between the two Z-axis auxiliary guide rails 250 is less than the distance between the two Z-axis auxiliary frames 421. This avoids interference between the two moving mechanisms.

[0062] Please refer to Figure 1 and Figure 3 The engraving platform 600 has an XY positioning coordinate 610 at one corner. Understandably, the XY positioning coordinate 610 is L-shaped.

[0063] For preferred options, please refer to [the provided text]. Figure 3 and Figure 4 The working area 410 of the base assembly 100, near the vertical mounting base 400, is also provided with a vent 130 to facilitate gas flow.

[0064] Specifically, please refer to Figure 6 The main unit housing 510 is also equipped with a handle 550 to improve the portability of the main unit housing 510.

[0065] Specifically, please refer to Figure 1 , Figure 3 and Figure 4 The base assembly 100 has a groove 140 below the engraving platform 600. The groove 140 can collect dust generated during engraving and discharge it through the vent 130 and the exhaust assembly to avoid interfering with laser operation.

[0066] Generally, the violet laser 520 performs laser engraving downwards through the field lens 530. A galvanometer can also be set between the violet laser 520 and the field lens 530 as needed.

[0067] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0068] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0069] In summary, this utility model provides an electrically operated ultraviolet laser engraving machine with an internal engraving mechanism. The atomizing chamber is equipped with a heating circuit, which preheats the e-liquid within the chamber. When the ambient temperature is too low, the e-liquid remains in a liquid state, and the temperature can be further increased to maintain its activity level above room temperature, thereby increasing the vapor production and meeting the user's demand for large vapor volumes. In other words, this product is convenient for use in low-temperature environments while also maximizing vapor production.

[0070] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
