[0002] In the fields of modern decoration, handicraft production, and architecture, stone engraving products are highly favored for their unique artistic charm and durability. Traditional stone engraving mainly relies on manual engraving or mechanical engraving methods. Although manual engraving can exhibit exquisite artistic effects, its efficiency is extremely low, and it has extremely high requirements for the skills of engravers, making it difficult to achieve large-scale production; mechanical engraving, although improving production efficiency to a certain extent, has limited engraving accuracy, making it difficult to complete the engraving of complex patterns and fine textures, and it is prone to generate relatively large noise and dust pollution during the engraving process, having an adverse impact on the physical health of operators and the working environment. With the development of laser technology, laser engraving has gradually been applied to the field of stone engraving due to its advantages such as high precision, high efficiency, and non-contact processing. Laser engraving acts on the surface of the stone with a laser beam of high energy density, instantly melting or vaporizing the stone material, thereby achieving the engraving of patterns and facilitating rapid prototyping production and manufacturing through lasers; However, the existing engraving devices are inconvenient for auxiliary covering maintenance, dust extraction, and rapid operation control during stone engraving, affecting the operation and use efficiency; Therefore, in order to solve the above problems, a stone laser engraving device is proposed.

And inside the side wall of the lower support frame bar 161, a lower proximity switch one 171 and a lower proximity switch two 181 corresponding to the upper proximity switch one 170 and the upper proximity switch two 180 are assembled.

[0039] In this way, it is convenient to cooperate with covering and maintaining the working area. At the same time, by descending, the corresponding proximity switches are brought closer to each other, so that the circuit is connected to control the engraving work and the work of sucking dust. More specifically in this embodiment, a pressing frame bar 162 is assembled at the bottom of the upper cover frame 160, and the side wall at the bottom end of the pressing frame bar 162 is provided with an arc-shaped protrusion. An inner groove 163 corresponding to the pressing frame bar 162 is opened inside the side wall of the lower support frame bar 161, and an inner gasket 164 is glued inside the inner groove 163.

[0042] Assembly grooves 166 corresponding to the glass plate 165 are opened on the four side edges and the top of the upper cover frame 160, and air holes are evenly opened in the center of the glass plate 165 on the top of the upper cover frame 160. In this way, during assembly and use, it is convenient to perform auxiliary docking assembly, avoiding being unable to use due to damage to one side of the switch. At the same time, with the opening of the air holes on the top of the glass plate 165, it is convenient for subsequent auxiliary dust suction and removal.

[0043] Working principle: When in use, power is turned on to facilitate subsequent operation through the power distribution control cabinet 190 and the control buttons 191. Then, the stone to be engraved is placed above the auxiliary protrusion 142 on the surface of the stone placement table 140. Subsequently, the telescopic cylinder 120 is controlled by the control button 191 to retract and descend, thereby driving the lifting frame 110, the laser generating assembly 100, and the laser engraving head 101 to descend. At the same time, the upper cover frame 160 is also driven to descend. With the cooperation of the lower support frame bar 161, through the settings of the pressing frame bar 162 and the inner groove 163, it is convenient to form a relatively enclosed space after covering; When the pressing frame bar 162 is butted with the lower support frame bar 161, the upper proximity switch one 170 and the upper proximity switch two 180 assembled inside it respectively approach the corresponding lower proximity switch one 171 and lower proximity switch two 181, so as to facilitate the connection of the circuit. That is, when the upper proximity switch one 170 and the lower proximity switch one 171 approach, the control circuit of the laser generating assembly 100 is connected, enabling the laser generating assembly 100 to engrave the stone in cooperation with the laser engraving head 101; When the upper proximity switch two 180 and the lower proximity switch two 181 approach, the control circuit of the exhaust component 151 is connected, enabling the exhaust component 151 to suck in cooperation with the collection hopper 150 and the exhaust joint 1520, sucking the dust and foreign objects generated during laser engraving to avoid their diffusion and affecting the surrounding environment. The operation is simple and convenient, facilitating the enclosure maintenance and the handling of the corresponding dust while the laser-assisted engraving is rapidly formed, making the use operation more convenient and safe; It should be noted that in this application, the specific connection structure and working principle of the upper proximity switch one 170, the lower proximity switch one 171, the upper auxiliary switch one 172, the lower auxiliary switch one 173, the upper proximity switch two 180, the lower proximity switch two 181, the upper auxiliary switch two 182, and the lower auxiliary switch two 183, as well as the laser generating assembly 100 and the laser engraving head 101, all belong to the prior art, and corresponding products can be purchased in the market. For those skilled in the art, it belongs to common general knowledge and can be implemented through various implementation methods. No other special requirements are made in this application, as long as it can achieve the functions in this application, so no specific limitations are made here; During operation, with the settings of the upper auxiliary switch one 172, the lower auxiliary switch one 173, the upper auxiliary switch two 182, and the lower auxiliary switch two 183, it is convenient for auxiliary assembly. When in use, it is convenient to cooperate with the upper proximity switch one 170, the lower proximity switch one 171, the upper proximity switch two 180, and the lower proximity switch two 181 for auxiliary work, for dual use, to avoid being unable to use due to the damage of one group. At the same time, with the assembly of the upper cover frame 160 and the glass plate 165, it is convenient for direct observation, and the ventilation holes opened at the top also facilitate subsequent suction, making the operation control more convenient and efficient; During operation, after the air extraction component 151 sucks through the collection hopper 150, it enters the interior of the filter tank 1550 with the cooperation of the air outlet elbow 1541. With the cooperation of the filter liquid 1554, it is convenient to filter out the soot and foreign particles in the gas. Subsequently, the gas is discharged through the upper tank cover 1551 and the exhaust pipe 1552. At the same time, with the cooperation of the sewage discharge valve 1553, it is convenient to discharge the sewage after using for a period of time, facilitating the subsequent addition of new clean water for use; During use, with the cooperation of the lower support leg 131 and the telescopic inner leg 134, it is convenient to support and adjust the height of the operating table 130 according to the usage requirements. Subsequently, with the cooperation of the limit nut 137, it is tightened for auxiliary limiting, making the support more stable and the use more comfortable.
