[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 , the present invention provides a technical solution:

[0025] Example 1: A multi-directional and precise four-station laser marking machine: comprising an engraving table 1 and a vertical stand 3, wherein the vertical stand 3 is mounted on one side of the engraving table 1, a movable turntable 2 is rotatably mounted on the surface of the engraving table 1, and a fixed horizontal table 4 is mounted on one side of the surface of the vertical stand 3;

[0026] Laser marking multi-position installation unit, which is set on the surface of the movable turntable 2 and is used for multi-position and multi-station precise installation of the marking workpiece;

[0027] The workpiece mounting part includes a movable turntable 2, which is mounted on the central area of ​​the surface of the engraving table 1. A calibration mark 73 is provided in the central area of ​​the surface of the movable turntable 2. Four groups of mounting grooves 7 are arranged at intervals on the surface of the movable turntable 2. The mounting grooves 7 are arranged in a ring shape. A clamping guide rail 71 is installed inside the mounting groove 7. Two groups of movable ends are provided on the surface of the clamping guide rail 71. The two groups of movable ends on the surface of the clamping guide rail 71 move toward each other. A mounting fixture 72 is magnetically mounted on the movable end of the surface of the clamping guide rail 71, and the mounting fixture 72 is symmetrically arranged.

[0028] The laser marking multi-position workstation installation unit includes a marking adjustment part, which includes a first-level embedded guide rail 42. The first-level embedded guide rail 42 is embedded in the bottom of the fixed horizontal platform 4. The first-level embedded guide rail 42 is set into two groups. The main moving block 43 is installed on the moving end of the two groups of first-level embedded guide rails 42. The secondary embedded guide rail 44 is embedded in the side of the main moving block 43 close to the movable turntable 2. The moving end of the secondary embedded guide rail 44 is set into two groups. The two groups of secondary embedded guide rails 44 are installed on the moving end of the secondary anti-slip frame 44. The secondary anti-slip frame 441 is covered and fitted on the outer surface of the main moving block 43. The laser marking head 8 is installed on the outside of the secondary anti-slip frame 441. The laser marking head 8 is set into two groups.

[0029] A first-level anti-slip frame 431 is provided on the top of the main moving block 43 . The first-level anti-slip frame 431 is sleeved on the outer surface of the fixed horizontal platform 4 . The two ends of the first-level anti-slip frame 431 are fixed to both sides of the top of the main moving block 43 respectively.

[0030] In this embodiment, the movement of the moving ends of the two sets of first-level embedded guide rails 42 drives the main moving block 43 to move partially. When the main moving block 43 moves partially, the first-level anti-slip frame 431 installed above the main moving block 43 will synchronously follow and slide along the upper surface of the fixed horizontal platform 4. The first-level anti-slip frame 431 can avoid the risk of loosening of the main moving block 43 during high-frequency movement, while ensuring the smooth movement of the main moving block 43 and the smooth engraving of the two sets of laser marking heads 8 during the marking process.

[0031] A workpiece marking airflow and dust guiding unit is provided on one side of the fixed horizontal platform 4 close to the movable turntable 2 .

[0032] The workpiece marking airflow dust guide unit includes an airflow adsorption part, which includes an air silo mounting frame 5. The air silo mounting frame 5 is installed on one side of the vertical upright plate 3. The air silo mounting frame 5 is symmetrically arranged in two groups. The surfaces of the two groups of air silo mounting frames 5 are both installed with smoke suction filter bins 51. One end of the smoke suction filter bin 51 is opened, and one end of the smoke suction filter bin 51 is opened toward the calibration mark 73. An adsorption air pump 52 is installed on one side of the smoke suction filter bin 51.

[0033] The workpiece marking airflow dust guide unit also includes an airflow retention part, which includes an air fan mounting frame 6. The air fan mounting frame 6 is installed on the top of two groups of smoke and dust suction filter bins 51. Two groups of mirror-symmetrical air fan cavities 61 are opened on the surface of the air fan mounting frame 6. A fixing frame 62 is embedded between adjacent air fan cavities 61. Both ends of the fixing frame 62 are inserted into the air fan cavities 61, and return air fans 63 are installed at both ends of the fixing frame 62.

[0034] In this embodiment, when the return air fan 63 guides the smoke airflow downward, the adsorption air pump 52 will perform double-sided adsorption of the smoke gas guided downward through the smoke suction filter chamber 51, thereby ensuring the cleanliness of the Z-shaped workpiece surface during the laser marking process, making it easier for the operator to observe the real-time effect of the laser marking on the Z-shaped workpiece surface.

[0035] Working principle: When using this device, the operator first pre-calibrates the marking position of the laser marking head 8 before processing, so that the laser marking head 8 is calibrated to the calibration mark 73. At this time, the operator needs to operate the first-level embedded guide rail 42. The moving ends of the two sets of first-level embedded guide rails 42 move to drive the main moving block 43 to move. When the main moving block 43 moves, the first-level anti-slip frame 431 installed above the main moving block 43 will slide synchronously along the upper surface of the fixed horizontal table 4. The first-level anti-slip frame 431 can avoid the risk of the main moving block 43 loosening during high-frequency movement, and at the same time ensure the smooth movement of the main moving block 43, ensuring the smooth engraving of the two sets of laser marking heads 8 during the marking process.

[0036] When the calibration of the laser marking head 8 to the calibration mark 73 is completed, the laser marking head 8 reaches above the movable turntable 2. At this time, the operator takes the Z-shaped workpiece to be processed, and then rotates the movable turntable 2 according to the installation and calibration requirements of the Z-shaped workpiece, and then removes the other three sets of magnetically mounted mounting fixtures 72. Then, the operator inserts the Z-shaped workpiece into the set of mounting fixtures 72 that have not been removed, and then drives the movable turntable 2 to rotate, and then rotates and adjusts the Z-shaped workpiece. When the rotation and adjustment of the Z-shaped workpiece is completed, the mounting fixture 72 corresponding to the other end of the Z-shaped workpiece is magnetically fastened and installed, thereby completing the clamping of both ends of the Z-shaped workpiece, and then the engaging areas of the other two sets of mounting fixtures 72 are rotated toward the Z-shaped workpiece for installation so that the Z-shaped workpiece is covered with the inside of the fixture, thereby improving the clamping and fixing effect of the Z-shaped workpiece and ensuring the normal progress of the laser marking step;

[0037] When the Z-shaped workpiece is installed and calibrated, the operator starts the return air fan 63 installed in the air fan mounting frame 6 area to rotate. When the return air fan 63 rotates, the gas above will be blown continuously to the calibration mark 73 area, so that the smoke and dust generated in the marking and engraving steps in the calibration mark 73 area will be blown downward. At the same time, the engraving dust generated in the engraving area on the surface of the Z-shaped workpiece cannot gather on the surface of the Z-shaped workpiece. The adsorption air pump 52 also works synchronously with the return air fan 63. When the return air fan 63 guides the smoke and dust downward, the adsorption air pump 52 will absorb the smoke and dust gas guided downward on both sides through the smoke suction filter bin 51, so as to ensure the cleanliness of the surface of the Z-shaped workpiece during the laser marking process, so that the operator can observe the real-time effect of the laser marking on the surface of the Z-shaped workpiece.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
