[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Embodiment 1, please refer to Figures 1 - 5 , an automotive parts laser brand engraving device, including: Engraving Chamber 100, inside which a movable laser engraver 200 is assembled; Exhaust Duct 300, on the side of which a Filter Chamber 400 is assembled; Moving Rod 500, on the side of which a Support Base 600 is assembled. Place the parts in the Engraving Chamber 100, activate the Moving Rod 500 driven by the electric telescopic rod, so that the Moving Rod 500 drives the Support Base 600 to move towards the side close to the parts to perform corresponding clamping operations. Close the Engraving Chamber 100, move the Laser Engraver 200 to the designated position to perform corresponding engraving operations, activate the air extraction pump, and extract smoke and dust through the Exhaust Duct 300 and the Filter Chamber 400; The inside of the Engraving Chamber 100 is rotatably connected to a Wind Turbine 701, the top of the Support Base 600 is rotatably connected to a Rotating Shaft 702, the top of the Rotating Shaft 702 is fixedly connected to a Limiting Plate 703, and a transmission part for transmission is assembled between the Wind Turbine 701 and the Limiting Plate 703. The transmission part includes a Hydraulic Chamber 1 704 assembled on the side of the Wind Turbine 701. When extracting smoke and dust through the Exhaust Duct 300 and the Filter Chamber 400, the fast-flowing air current drives the Wind Turbine 701 to rotate rapidly, so that the Wind Turbine 701 drives the Hydraulic Chamber 1 704 assembled on its side to rotate rapidly.

[0022] The inner wall of the first hydraulic chamber 704 is connected with a movable block 706 through the arrangement of a first spring 705, and the side surface of the first hydraulic chamber 704 is slidably connected with an arc-shaped plate 707 through the arrangement of a piston. When the first hydraulic chamber 704 rotates rapidly, the movable block 706 in the first hydraulic chamber 704 is stretched by the first spring 705 under the action of centrifugal force and slides along the inner wall of the first hydraulic chamber 704, thereby squeezing the oil in the first hydraulic chamber 704, causing the oil originally stored in the first hydraulic chamber 704 to flow towards one end close to the arc-shaped plate 707, driving the arc-shaped plate 707 to move out of the first hydraulic chamber 704.

[0023] The inner wall of the engraving chamber 100 is equipped with a second hydraulic chamber 708. The side surface of the second hydraulic chamber 708 is slidably connected with a first force-bearing rod 709 through the arrangement of a piston. The first force-bearing rod 709 is located on the side of the arc-shaped plate 707 and is in contact with the arc-shaped plate 707. A second spring 710 is assembled on the side surface of the first force-bearing rod 709. A hose 711 is assembled at the bottom of the second hydraulic chamber 708. The side surface of the support base 600 is equipped with a third hydraulic chamber 712. The side surface of the third hydraulic chamber 712 is slidably connected with a first arc-shaped rod 713 through the arrangement of a piston. The first arc-shaped rod 713 is located on the side of the limiting plate 703 and is in a fixed state with the limiting plate 703. When the arc-shaped plate 707 moves out synchronously during rotation, it can squeeze the first force-bearing rod 709, driving the first force-bearing rod 709 to move sideways. Cooperating with the second hydraulic chamber 708 that is slidably connected with the first force-bearing rod 709 through the arrangement of a piston, it can push the oil in the second hydraulic chamber 708, causing the oil in the second hydraulic chamber 708 to flow into the hose 711. The oil in the hose 711 then flows into the third hydraulic chamber 712, causing the oil originally stored in the third hydraulic chamber 712 to flow towards the first arc-shaped rod 713, thereby driving the first arc-shaped rod 713 to extend out of the third hydraulic chamber 712, causing the first arc-shaped rod 713 to drive the limiting plate 703 fixedly connected thereto to rotate, and the limiting plate 703 then rotates to the top position of the component, restricting the component to a certain extent and preventing the component from being affected by the airflow, improving the stability of the device during use.

[0024] After the engraving operation is completed and the extraction of smoke and dust is stopped, the wind wheel 701 stops rotating accordingly, and the movable block 706 loses the action of centrifugal force, so it can be reset under the action of the first spring 705. Similarly, the arc-shaped plate 707 is reset. The first force-bearing rod 709 loses the action of the arc-shaped plate 707, so it can be reset under the action of the second spring 710. Similarly, the first arc-shaped rod 713 drives the limiting plate 703 to reset, facilitating the next activation of the device.

[0025] During use, place the component in the engraving chamber 100, activate the moving rod 500 driven by the electric telescopic rod, so that the moving rod 500 drives the support base 600 to move towards the side close to the component, perform corresponding clamping operations on the component, close the engraving chamber 100, move the laser engraver 200 to the designated position, and perform corresponding engraving operations. Activate the air extraction pump, and extract smoke and dust through the air extraction pipeline 300 and the filtration chamber 400. The rapidly flowing air drives the wind wheel 701 to rotate rapidly, so that the wind wheel 701 drives the hydraulic chamber one 704 assembled on its side to rotate rapidly. Under the action of centrifugal force, the movable block 706 in the hydraulic chamber one 704 stretches the first spring 705 and slides along the inner wall of the hydraulic chamber one 704, thereby squeezing the oil in the hydraulic chamber one 704, causing the oil originally stored in the hydraulic chamber one 704 to flow towards one end close to the arc plate 707, driving the arc plate 707 to move out of the hydraulic chamber one 704. At this time, the arc plate 707 moves out synchronously during the rotation process, thereby squeezing the first force-bearing rod 709, driving the first force-bearing rod 709 to move sideways. Cooperating with the hydraulic chamber two 708 that is slidably connected to the first force-bearing rod 709 through a piston, the oil in the hydraulic chamber two 708 can be pushed, so that the oil in the hydraulic chamber two 708 flows into the hose 711, and the oil in the hose 711 then flows into the hydraulic chamber three 712, causing the oil originally stored in the hydraulic chamber three 712 to flow towards the arc rod one 713, thereby driving the arc rod one 713 to extend out of the hydraulic chamber three 712, causing the arc rod one 713 to drive the limiting plate 703 fixedly connected to it to rotate, and the limiting plate 703 then rotates to the top position of the component to impose certain restrictions on the component; after the engraving operation is completed, after stopping the extraction of smoke and dust, the wind wheel 701 stops rotating accordingly, and the movable block 706 loses the action of centrifugal force, and can be reset under the action of the first spring 705. Similarly, the arc plate 707 is reset. The first force-bearing rod 709 loses the action of the arc plate 707 and can be reset under the action of the second spring 710. Similarly, the arc rod one 713 drives the limiting plate 703 to reset.

[0026] Embodiment 2. Please refer to Figures 1 - 6 , on the basis of Embodiment 1, an auxiliary adsorption assembly 800 for adsorbing components is assembled on the side of the support base 600. The auxiliary adsorption assembly 800 includes a rotating rod 801 rotatably connected to the side of the moving rod 500. One end of the rotating rod 801 is fixedly connected to a first articulated rod 802. The first articulated rod 802 is located at the top position of the arc rod one 713 and is in an articulated state with the arc rod one 713. The other end of the rotating rod 801 is fixedly connected to a second articulated rod 803. When the arc rod one 713 moves, it can drive the first articulated rod 802 articulated with it to move sideways. Also, because the first articulated rod 802 is fixedly connected to the rotating rod 801, during the movement of the first articulated rod 802, with Figure 6As shown in the figure, the rotating rod 801 is driven to rotate counterclockwise by a certain angle, so that the rotating rod 801 drives the second articulated rod 803 fixedly connected thereto to rotate counterclockwise by a certain angle synchronously.

[0027] Suction cups 804 and pneumatic chambers 805 are respectively assembled on the sides of the support base 600. A connecting rod 806 is slidably connected to the side of the pneumatic chamber 805 through a piston. The connecting rod 806 is located on the side of the second articulated rod 803 and is in an articulated state with the second articulated rod 803. When the second articulated rod 803 rotates counterclockwise by a certain angle and is in an articulated state with the connecting rod 806, and the connecting rod 806 is restricted by the pneumatic chamber 805 slidably connected to it through a piston, when the second articulated rod 803 moves, the connecting rod 806 moves out of the pneumatic chamber 805. When the support base 600 initially clamps the parts, the suction cup 804 simultaneously performs an initial adsorption operation on the parts. As the connecting rod 806 moves, the residual gas between the suction cup 804 and the parts can be extracted into the pneumatic chamber 805 through the pneumatic chamber 805, thereby improving the adsorption effect of the suction cup 804 on the parts in this case and further improving the stability of the device during use.

[0028] And when the first arc-shaped rod 713 is reset, the connecting rod 806 can be reset synchronously to facilitate the next activation of the device.

[0029] During use, on the basis of Embodiment 1, when the first arc-shaped rod 713 moves, it can drive the first articulated rod 802 hinged to it to move laterally. Also, because the first articulated rod 802 is fixedly connected to the rotating rod 801, when the first articulated rod 802 moves, Figure 6 As shown in the figure, the rotating rod 801 is driven to rotate counterclockwise by a certain angle, so that the rotating rod 801 drives the second articulated rod 803 fixedly connected thereto to rotate counterclockwise by a certain angle synchronously. The second articulated rod 803 is in an articulated state with the connecting rod 806, and the connecting rod 806 is restricted by the pneumatic chamber 805 slidably connected to it through a piston. When the second articulated rod 803 moves, the connecting rod 806 moves out of the pneumatic chamber 805. When the support base 600 initially clamps the parts, the suction cup 804 simultaneously performs an initial adsorption operation on the parts. As the connecting rod 806 moves, the residual gas between the suction cup 804 and the parts can be extracted into the pneumatic chamber 805 through the pneumatic chamber 805; and when the first arc-shaped rod 713 is reset, the connecting rod 806 can be reset synchronously.

[0030] Embodiment 3, please refer to Figures 1 - 9, based on the first and second embodiments, an auxiliary cleaning component 900 for cleaning is assembled inside the filter chamber 400. The auxiliary cleaning component 900 includes a filter plate 901 assembled inside the filter chamber 400. An elastic cam 902 is assembled on the side of the wind wheel 701. A through hydraulic chamber four 903 is assembled inside the filter chamber 400. One end of the hydraulic chamber four 903 is slidably connected with a force receiving rod two 904 through a piston. The force receiving rod two 904 is located on the side of the elastic cam 902 and is in contact with the elastic cam 902. When the wind wheel 701 is in a rotating state, it can drive the elastic cam 902 assembled on its side to rotate together. When the protruding part of the elastic cam 902 rotates to the position of the force receiving rod two 904, it can squeeze the force receiving rod two 904. The force receiving rod two 904 is squeezed and slides into the hydraulic chamber four 903, so that the force receiving rod two 904 pushes the oil in the hydraulic chamber four 903.

[0031] The other end of the hydraulic chamber four 903 is slidably connected with an arc-shaped rod two 905 through a piston. A torsion spring rod 906 is rotatably connected inside the filter chamber 400. A cleaning plate 907 is fixedly connected to the outside of the torsion spring rod 906. The cleaning plate 907 is located on the side of the arc-shaped rod two 905 and is in contact with the arc-shaped rod two 905. When the oil in the hydraulic chamber four 903 is pushed by the force receiving rod two 904, the oil immediately flows towards the side close to the arc-shaped rod two 905 and drives the arc-shaped rod two 905 to extend out of the hydraulic chamber four 903, so that the arc-shaped rod two 905 drives the cleaning plate 907 to rotate by a certain angle. When the protruding part of the elastic cam 902 continues to rotate and moves away from the position of the force receiving rod two 904, the cleaning plate 907 loses the acting force and can be reset under the action of the torsion spring rod 906. In this way, the cleaning plate 907 can reciprocally rotate on the side of the filter plate 901 to perform a simple cleaning to a certain extent, prevent the filter plate 901 from being completely blocked due to long-term use, reduce the manual cleaning frequency, and improve the use efficiency of the device.

[0032] In use, on the basis of the first and second embodiments, when the wind turbine 701 is in a rotating state, it can drive the elastic cam 902 assembled on its side to rotate together. When the protruding part of the elastic cam 902 rotates to the force receiving rod two 904, it can squeeze the force receiving rod two 904. The force receiving rod two 904 is squeezed and slides into the hydraulic chamber four 903, causing the force receiving rod two 904 to push the oil in the hydraulic chamber four 903. The oil then flows toward the side close to the arc rod two 905 and drives the arc rod two 905 to extend from the hydraulic chamber four 903, causing the arc rod two 905 to drive the cleaning plate 907 to rotate at a certain angle. When the protruding part of the elastic cam 902 continues to rotate away from the force receiving rod two 904, the cleaning plate 907 loses the acting force and can be reset under the action of the torsion spring rod 906. In this way, the cleaning plate 907 can rotate reciprocally on the side of the filter plate 901 to perform a simple cleaning to a certain extent.

[0033] As mentioned above, the above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
