[0036] ​​The dust removal assembly 5 is fixedly installed on the side wall of the second mounting plate 32. Through the cooperation of the first synchronous wheel 516, the second synchronous wheel 517 and the synchronous belt 518, the reciprocating screw rod 55 is rotated, the second threaded sleeve 56 and the piston plate 58 are driven to reciprocate up and down, and the pressure difference is continuously generated during the rotation of the polishing head 43. The debris at the marking position and the air are sucked into the separation box 53 for debris-gas separation. The gas is cooled by the cold plate 515 when entering the sealed box 52, and finally discharged through the air blowing pipe 513, so as to cool the marking position and speed up the forming. The debris is concentrated and guided to the dust suction port 510 through the arc-shaped guide plate 415, so as to conveniently collect the debris, avoid excessive dispersion of the debris, and affect the subsequent laser marking. The cavity 11 is formed in the inner wall of the operation table 1, and the correction assembly 6 is fixedly installed in the cavity 11.

[0037] The polishing assembly 4 comprises a motor 41 fixedly connected to the top end of the second mounting plate 32, an output end of the motor 41 fixedly connected with a transmission shaft 42, one end of the transmission shaft 42 penetrating through the side wall of the second mounting plate 32 and fixedly connected with a polishing head 43, a threaded rod 46 rotatably connected to the bottom end of the first mounting plate 3, first supports 44 fixedly connected to the top end of the second mounting plate 32 in a symmetrical manner, a first threaded sleeve 45 fixedly connected to the two first supports 44, the first threaded sleeve 45 being in threaded connection with the outer wall of the threaded rod 46, second supports 49 fixedly connected to the bottom end of the second mounting plate 32 in a symmetrical manner, a first sleeve 410 slidably connected to the two second supports 49, third supports 411 fixedly connected to the bottom end of the second mounting plate 32 in a symmetrical manner, and a second sleeve 412 slidably connected to the two third supports 411.

[0038] One end of the threaded rod 46 is fixedly connected to a telescopic rod 47. One end of the telescopic rod 47 passes through the side wall of the second mounting plate 32 and is fixedly connected to an incomplete gear 48. A first sleeve 410 is slidably embedded in and connected to the side wall of one end of the telescopic rod 47. A second sleeve 412 is fitted onto the outer wall of the drive shaft 42. A cylindrical gear 413 is fixedly connected to the bottom end of the second sleeve 412. The incomplete gear 48 and the cylindrical gear 413 mesh with each other at their teeth. The telescopic rod 47, the second bracket 49, and the first sleeve 410 are configured such that the lengths of the second bracket 49 and the third bracket 411 are equal. Thus, during the downward movement of the second mounting plate 32, the first sleeve 410 slides inside the telescopic rod 47, thereby allowing the telescopic rod 47 to open its side length, ensuring that the teeth of the incomplete gear 48 and the cylindrical gear 413 are always in a meshing state. The drive shaft 42 passes through the side wall of the cylindrical gear 413, and the cylindrical gear 413 is sleeved on the outside of the drive shaft 42, without contacting or affecting each other.

Then, the laser marking machine body 2 is vertically adjusted to perform focusing operation, and the position of the laser marking head is moved to the required marking position, and then the laser marking operation begins.

[0040] Before the laser marking operation begins, the electric push rod 31 is activated, which drives the second mounting plate 32 to descend until the grinding head 43 contacts the workpiece surface. The motor 41 is then activated, which drives the transmission shaft 42 and the grinding head 43 to rotate. This grinds the area on the stainless steel surface that needs to be marked before the laser marking operation. By increasing the roughness of the marking area, laser reflection is avoided, which is beneficial to the normal operation of laser marking and improves the safety of the device.

[0041] In the polishing process, the polishing head 43 rotates along the transmission shaft 42 to produce debris, which is dispersed outward in a circular manner and is not convenient to collect; by moving the polishing head 43 downward to the surface of the stainless steel, the first bracket 44 fixed to the top end of the second mounting plate 32 is driven to move downward synchronously, and under the cooperation of the first threaded sleeve 45 and the threaded rod 46, the threaded rod 46 and the incomplete gear 48 are rotated, the incomplete gear 48 and the cylindrical gear 413 are meshed and connected at the teeth, the cylindrical gear 413 and the guide plate 415 are driven to rotate one hundred and eighty degrees, the arc-shaped guide plate 415 is rotated to the outside of the polishing head 43, and the debris produced in the polishing process is arc-guided, which is conducive to guiding the debris to the dust suction port 510 for concentrated collection, avoiding excessive dispersion of the debris and affecting the quality of subsequent laser marking.
