[0030] The angle of the bending structure of the top plate 17 is 90 degrees, the blowing fan 3 at the bending position faces the first through port 202 in the inside of the support frame 1, the upper end of the ash storage box 204 is provided with an inclination of 30 degrees to one side, the upper end of the workpiece storage box 205 is provided with an inclination of 30 degrees to the other side, the two sides of the support frame 1 are both fixedly connected with side plates 9, a plurality of ventilation holes 10 are horizontally arranged on the surface of the side plates 9.

[0031] The movable platform 7 comprises a positioning table 701 arranged between the support frame 8 and the inner support frame 12, the rear side of the upper end surface of the positioning table 701 is fixedly connected with an electric push column 702, the front side of the upper end surface of the positioning table 701 is fixedly connected with two fixed plates 704, the front end of the fixed plate 704 is fixedly connected with a guide column 706, the surface of the guide column 706 is sleeved with a spring 705, the two guide columns 706 and the front end output end of the electric push column 702 are both provided with positioning plates 707, the two ends of the positioning plate 707 are both provided with movable holes, the movable holes are sleeved on the guide column 706, then the guide column 706 has a guiding property for the transverse displacement of the whole positioning plate 707, the opposite end surfaces of the two positioning plates 707 are paved with anti-skid pads, the special curved surface workpiece is clamped between the two positioning plates 707.

[0032] The guide groove 703 is transversely arranged through the upper end of the positioning table 701, the guide grooves 703 are arranged in front and back array, the guide grooves 703 and the air holes 10 on the end face of the side plate 9 are in the same horizontal position, when the whole movable platform 7 is in the horizontal position, the protrusion 604 on the extrusion block 601 extrudes the whole positioning plate 707 to the special-shaped curved surface workpiece, so that the whole positioning plate 707 can extrude the springs 705 on both sides when it is displaced, which makes the elastic force of the spring 705 shrink, and then the side of the whole positioning plate 707 with the non-slip pad can be attached to the end face of the special-shaped curved surface workpiece, and the electric push column 702 operates, then the output end of one end of the electric push column 702 can drive the transverse displacement of the positioning plate 707, and then the positioning plate 707 on the rear side can extrude the rear end face of the special-shaped curved surface workpiece, so as to realize the positioning of the special-shaped curved surface workpiece, and when the movable platform 7 is in the horizontal position, the guide grooves 703 and the air holes 10 on the end face of the side plate 9 are in the same horizontal position;

[0033] The extrusion part 6 includes an extrusion block 601 fixedly connected to the upper end of the support frame 8, a protrusion 604 fixedly connected to the rear side of the upper end of the extrusion block 601, an upper recess 602 provided on one side of the upper end of the extrusion block 601, and a lower recess 603 movably provided on the other side of the upper end of the extrusion block 601. The positions between the lower recess 603 and the protrusion 604 and between the lower recess 603 and the upper recess 602 are all provided with a circular chamfered curved surface structure, which makes the transition between the lower recess 603 and the protrusion 604 and between the lower recess 603 and the upper recess 602 more smooth. This smooth setting enables the rear end face of the extrusion block 601 to slide with the front end face of the positioning plate 707 when they are attached.

[0034] The interiors of the first baffle 13 and the second baffle 14 are all hollow structures, and triangular supports are arranged in the hollow structures. This arrangement makes the interiors of the first baffle 13 and the second baffle 14 have a large space, thereby reducing their own weight, and the triangular supports arranged in the hollow structures can enhance the firmness of the first baffle 13 and the second baffle 14.

[0035] When the whole device is used, first, the whole special-shaped curved surface workpiece is clamped on the positioning table 701, the protrusion 604 on the upper end of the extrusion block 601 extrudes the positioning plate 707, so that the rear end face of the front positioning plate 707 can be extruded on the end face of the special-shaped curved surface workpiece, the output end of the front side of the electric push column 702 is fixedly connected with the positioning plate 707, and the output end of the electric push column 702 drives the forward extrusion of the positioning plate 707, so as to extrude and position the whole special-shaped curved surface workpiece.

[0036] After the overall special-shaped curved workpiece is positioned, the two-axis movable platform 15 and the laser engraving head 16 are opened. The linear motor on the two-axis movable platform 15 drives the laser engraving head 16 to move laterally on the X-axis and Y-axis, so that the laser engraving head 16 performs laser engraving processing on the special-shaped curved workpiece located on the lower side. At this time, the position of the special-shaped curved workpiece is shown in the horizontal position in FIG. 7. Figure 4

[0037] When the position of the special-shaped curved workpiece is in the horizontal position, smoke will be generated during the laser engraving processing of the special-shaped curved workpiece. At this time, the suction fan 4 in the middle of the upper end of the top plate 17 is opened, so that the rotation of the fan blades of the suction fan 4 can exhaust the smoke in the inside of the support frame 1 to the outside. The guide groove 703 and the ventilation hole 10 on the end surface of the side plate 9 are in the same horizontal position. The gas on the outside of the support frame 1 enters the inside of the support frame 1 through the ventilation hole 10, so as to ventilate and exhaust the smoke in the inside of the support frame 1 to the upper side of the suction fan 4. The upper end of the suction fan 4 can be connected with a pipeline, and the pipeline is directly connected with a pollution gas treatment room outside the factory building. The pollution gas treatment room processes the exhaust smoke.

[0038] After the laser engraving processing of the special-shaped curved workpiece, the rotating shaft at the front end of the servo motor 11 on the upper end of the inner support frame 12 drives the positioning table 701 to rotate to the direction of the first opening 202 by 30 degrees. At this time, the suction fan 4 is closed, and the blowing fan 3 is opened to blow air into the inside of the support frame 1. After the laser engraving processing of the special-shaped curved workpiece on the positioning table 701, some ash will be accumulated in the guide groove 703 on the positioning table 701. The blowing fan 3 is opened to blow air to the guide groove 703 and the special-shaped curved workpiece on the positioning table 701. This arrangement enables the ash in the guide groove 703 to be blown and fall into the ash storage box 204 for deposition. At this time, the position state of the movable platform 7 and the special-shaped curved workpiece is shown in FIG. 8. Figures 6 to 7

[0039] After the smoke and ash after the laser engraving are processed, the rotating shaft at the front end of the servo motor 11 drives the positioning table 701 to rotate to the direction of the second opening 203 and tilt by 30 degrees. At this time, the blowing fan 3 and the suction fan 4 are closed. During the continuous rotation of the positioning table 701 to the direction of the second opening 203, the protrusion 604 on the upper end of the extrusion block 601 no longer extrudes the positioning plate 707 at the front end. The stretching elastic force of the fixed plate 704 at the front end drives the positioning plate 707 to move to the direction of the extrusion block 601. This arrangement enables the positioning plate 707 on the front side to gradually move into the upper groove 602 and the lower groove 603, so that the positioning plate 707 on the front side no longer extrudes the special-shaped curved workpiece. The special-shaped curved workpiece tilts on the positioning table 701 and finally falls into the workpiece storage box 205 through the second opening 203 for storage. At this time, the position state of the movable platform 7 and the special-shaped curved workpiece is shown in FIG. 9. Figures 8 to 10 ​​as shown.

[0040] In summary, through the above settings and operations, the overall movable platform 7 is in three states. When the movable platform 7 is inclined to the first opening 202 by 30 degrees, the overall device recycles the ash on the positioning table 701. When the movable platform 7 is in a horizontal state, the overall device processes the smoke dust generated after laser engraving. When the movable platform 7 is inclined to the second opening 203 by 30 degrees, the overall device collects and stores the special-shaped curved workpiece clamped on the positioning table 701.

[0041] It will be obvious to a person skilled in the art that the application is not limited to the details of the above-described exemplary embodiments, but that the application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application. The embodiments should therefore be considered in all respects as illustrative and not restrictive, the scope of the application being defined by the appended claims rather than by the above description, and it is therefore intended that all changes and modifications that fall within the meaning and range of equivalency of the elements of the claims are encompassed by the application. Any reference signs in the claims should not be construed as limiting the claims concerned.
