Through the arrangement, the preloading force is applied to at least one lifting rod 210 far away from the suspension end of the long arm slide rail 110, the lifting rod 210 closest to the suspension end of the long arm is enabled to keep the preloading force state, through the lever principle, the lifting rod 210 without the preloading force is used as a lever point, the generated tilting force of the long arm slide rail 110 at the far end is offset through the preloading force, the effect of offsetting the tilting tendency is achieved, the levelness of the long arm slide rail 110 is ensured, and therefore the laser marking head is accurate when sliding on the long arm slide rail 110. For a lifter bar that applies a greater preload force away from the long arm lifter than the lifter bar closest to the free end of the long arm, the application of load by the lever principle to counteract the effects of the roll tendency should be considered equivalent to the above.

Specifically, the second driving mechanism may be two independent servo motors, both of which are fixedly connected to the machine platform, and the two servo motors are respectively in driving connection with the two lifting rods 210, and as can be understood, the laser marking machine further includes a control system connected with the servo motors in a matching manner, a power supply for driving the servo motors to operate, and the like; the servo motor is connected to the lift rod 210, which is away from the cantilever end of the long arm sliding rail 110, and provides a preload force through the control system, so that the lift rod 210 generates an overturning force on the lift table 100 to counteract the overturning force on the lift table 100 generated by the self weight of the suspended end of the long arm sliding rail 110, thereby ensuring the levelness of the long arm sliding rail 110 and ensuring the precision of the laser marking head when the laser marking head slides on the long arm sliding rail 110.
