Description

Technical Field

[0001] This application relates to the field of Blu-ray engraving technology, and in particular to a desktop portable Blu-ray engraving machine. Background Technology

[0002] Blue light engraving machines are widely used in material processing, using blue light to engrave on materials. In smaller processing scenarios, such as small metal sign making, leather cutting, and DIY hand cutting, the use of small blue light engraving machines requires close-range operation, posing a risk of eye damage to workers as the blue light can directly or be reflected from the material. Therefore, protective structures are necessary when using blue light engraving machines.

[0003] Existing protective structures generally consist of protective goggles and independent protective cabins. Protective goggles, worn by workers to protect their face or eyes, increase the complexity of the processing. Independent protective cabins are enclosed structures installed on the engraving machine, blocking blue light leakage through a complete shell. While this solves the eye protection problem, the fully enclosed structure requires a more complex shell design and supporting installation structure, significantly increasing the production and assembly costs of the equipment.

[0053] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments in this application specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection claimed in this application.

They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0055] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0056] Please see Figures 1 to 3 The desktop portable blue light engraving machine provided in this application embodiment includes: a laser head 30, an adjustment component 10, and a shell frame 20; a grip handle 21 is provided on the top of the shell frame 20; an upper chamber 201 and a lower chamber 202 are provided inside the shell frame 20; the upper chamber 201 is located above the lower chamber 202; the lower chamber 202 opens downwards; a viewing window 22 is provided on the side wall of the lower chamber 202; the adjustment component 10 is located inside the upper chamber 201; and the laser head 30 is located in the adjustment component 10.

[0057] In this solution, the grip handle 21 on the top of the outer shell frame 20 can be directly held by the staff, making it convenient for the equipment to be moved and adjusted in desktop scenarios, thus improving the ease of carrying and processing.

[0058] In this solution, the laser head 30 is a standard configuration in existing blue light engraving machines. This embodiment can use existing laser emitting devices, such as existing blue light emitters. After being electrically connected to the button 27 on the outer shell frame 20, the power supply of the blue light engraving machine can be controlled by the button 27.

[0059] In this solution, the positioning component 10 can adjust the position of the laser head 30.

[0060] In this design, the upper chamber 201 and the lower chamber 202 form a separate cavity structure within the outer shell frame 20, which can increase the distance between the positioning component 10 and the processing part, reducing the impact of dust on the positioning component 10 during processing. Specifically, the lower chamber 202 can be configured to have a greater height than the upper chamber 201, so as to achieve the above-mentioned effects while facilitating the entry of the processing part into the lower chamber 202 and reducing the impact of dust on the laser head 30.

[0061] This solution is suitable for scenarios where small parts are processed on a tabletop, such as engraving and cutting materials like wood, cardboard, and leather. The operator can lift the engraving machine by holding the handle 21, making it easy to move. As one implementation, in the application scenario of the Blu-ray engraving machine provided in this embodiment, the workpiece to be cut is not fixed; for example, when cutting wood, one end of the wood can extend outside the cutting machine. Simultaneously, the operator can directly lift the handle 21, move the lower chamber 202 above the workpiece, and then start the equipment for processing.

[0062] In one implementation, during processing, the operator can directly lift the gripping handle 21 to move the lower chamber 202 above the workpiece and cover it. Then, the laser head 30 and the positioning component 10 are activated, causing the laser head 30 to move along a preset path under the control of the positioning component 10. The blue laser engraving machine may contain a processor; the processor is electrically connected to the positioning component 10 and the laser head 30. After an external data cable is electrically connected to the processor, path data can be transmitted to the processor, which then controls the laser head 30 to move and process according to the path data. Taking the engraving / cutting of a triangle from a wooden board using the blue laser engraving machine of this solution as an example, during operation, it is only necessary to ensure that the cutting path is completely on the wooden board. After the operator starts the equipment, the laser head 30 will move along the path of the triangle to perform engraving / cutting.

[0063] In one embodiment, the lower chamber 202 has a downward-facing flared structure.

[0064] The flared structure increases the opening area at the bottom of the lower chamber 202, making it easier to place the workpiece stably when not in use and to cover the workpiece when in use.

[0065] Furthermore, the outer shell frame 20 has a left-right symmetrical structure; the upper chamber 201 is located directly above the lower chamber 202; the projection of the lower chamber 202 along the vertical direction covers the projection of the upper chamber 201 along the vertical direction.

[0066] The symmetrical outer shell frame 20 keeps the device's center of gravity as central as possible, preventing it from tipping over when moved by hand gripping the handle 21 and maintaining a level position when placed on a desktop, thus reducing the risk of tipping over due to a shift in the center of gravity. Meanwhile, the upper chamber 201 positioned directly above the lower chamber 202 allows for a more compact overall structure, reducing lateral space requirements and making it more suitable for processing in confined desktop spaces.

[0067] In one embodiment, a mounting groove 23 is provided at the bottom of the side wall of the lower chamber 202; a friction pad 24 is provided in the mounting groove 23.

[0068] The friction pad 24 can increase the friction between the outer shell frame 20 and the table or workpiece, reducing the displacement of the outer shell frame 20 due to vibration during processing when the workpiece is covered.

[0069] In one embodiment, the system further includes an exhaust fan 40; an exhaust port 25 is provided on the side wall of the outer casing frame 20; the exhaust fan 40 is positioned inside the outer casing frame 20 corresponding to the position of the exhaust port 25.

[0070] Specifically, the exhaust fan 40 can be installed in the lower chamber 202. The exhaust fan 40 can discharge the fumes generated during processing in the lower chamber 202 through the exhaust port 25, preventing the fumes from adhering to the adjustment component 10 and the laser head 30, and reducing the impact of fumes on the processing effect of the equipment.

[0071] Furthermore, the exhaust vent 25 is equipped with absorbent cotton. The absorbent cotton can coarsely filter the smoke and dust emitted by the exhaust fan 40, intercepting smoke particles and odor molecules, preventing direct emission and pollution of indoor air, and improving the working environment. In practical applications, the absorbent cotton can be replaced periodically.

[0072] In a more specific embodiment, please refer to Figures 1 to 5 The positioning assembly 10 includes: a first slide rail 11 and a second slide rail 12; the first slide rail 11 is fixed inside the outer shell frame 20; the second slide rail 12 is slidably disposed on the first slide rail 11 along the x-axis direction; the laser head 30 is slidably disposed on the second slide rail 12 along the y-axis direction; both the x-axis and y-axis directions are horizontal and perpendicular to each other. The x-axis and y-axis directions can be configured as follows: Figure 4 As shown in the image.

[0073] In this embodiment, a first guide rod 111 can be provided on the first slide rail 11; a second guide rod 123 can be provided on the second slide rail 12. The first guide rod 111 and the second guide rod 123 can respectively serve as sliding guides for the second slide rail 12 and the laser head 30.

[0074] In this embodiment, a protrusion 121 may be provided on the second slide rail 12; an I-shaped slider 122 is fixed on the protrusion 121. The I-shaped slider 122 is slidably connected to the first guide rod 111. Similarly, the laser head 30 may have an I-shaped slider on its top to connect to the second guide rod 123.

[0075] Meanwhile, the first slide rail 11 and the second slide rail 12 are equipped with driving components, which can drive the second slide rail 12 and the laser head 30 to move linearly, respectively.

[0076] In one embodiment, the positioning assembly 10 includes: a first lead screw 13 and a second lead screw 14; the first lead screw 13 is arranged parallel to the side of the first slide rail 11; the second slide rail 12 is engaged with the first lead screw 13; the second lead screw 14 is arranged parallel to the side of the second slide rail 12; and the laser head 30 is engaged with the second lead screw 14.

[0077] Correspondingly, both the first lead screw 13 and the second lead screw 14 are connected to a rotary motor 17 to drive them to rotate. When the first lead screw 13 rotates, the second slide rail 12 can move along the x-axis under the guidance of the first guide rod 111. When the second lead screw 14 rotates, the laser head 30 can move along the y-axis under the guidance of the second guide rod 123.

[0078] Furthermore, the positioning assembly 10 includes: a first guide rod 15 and a second guide rod 16; the first guide rod 15 is arranged parallel to the side of the first slide rail 11; the second slide rail 12 is slidably sleeved on the first guide rod 15; the second guide rod 16 is arranged parallel to the side of the second slide rail 12; and the laser head 30 is slidably sleeved on the second guide rod 16.

[0079] In this embodiment, the first guide rod 15 may include multiple rods, symmetrically arranged on both sides of the first slide rail 11. The second guide rod 16 may include multiple rods, symmetrically arranged on both sides of the second slide rail 12. The first guide rod 15 and the second guide rod 16 can improve the stability of guiding the second slide rail 12 and the laser head 30, ensuring the stability of the laser head 30 moving along the preset path.

[0080] In practical applications, the outer shell frame 20 is equipped with a start / stop indicator light 26 to indicate whether the blue light engraving machine is powered on.

[0081] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features.
