[0029] Please see attached Figure 4 The instruction system includes a laser radar obstacle avoidance control system 11, a wide preset system 12, an identification input and parameter control system 13, an intelligent six-axis servo arm control system 14 and an end safety distance locking system 15 electrically connected to the computer control system 2; the laser radar obstacle avoidance control system 11 is electrically connected to the first radar obstacle avoidance and infrared laser transmitter 6 and the second radar obstacle avoidance and infrared laser transmitter 7, the wide preset system 12 is electrically connected to the first radar obstacle avoidance and infrared laser transmitter 6 and the second radar obstacle avoidance and infrared laser transmitter 7; the intelligent six-axis servo arm control system 14 is electrically connected to the six-axis robotic arm 1; the end safety distance locking system 15 is electrically connected to the end safety distance locking laser 10.

If there are protrusions or obstacles, the computer control system 2 can be triggered to control the six-axis robot arm 1 to avoid them, so as to prevent the laser marking machine 8 from colliding with the protrusions or obstacles and being damaged.

[0031] The wide-width preset system 12 can be used to set the laser emission angles of the first radar obstacle avoidance and infrared laser emission integrated device 6 and the second radar obstacle avoidance and infrared laser emission integrated device 7, thereby controlling the projection amplitude of the laser on the surface of the component so that it can match the range of the marking area.

[0032] Preferably, the marking input and parameter control system 13 can use the keyboard, mouse and other devices of the prior art to input the marking content. The terms and symbols of the engineering marking can be preset in the computer control system 2, so that the required terms and symbols can be retrieved through the marking input and parameter control system 13, and the parameters such as the size, arrangement and combination of the selected terms and symbols can be adjusted, such as horizontal marking, vertical marking, oblique marking, etc., without the need to prepare a large number of "templates" or "masks" in advance, and the customized needs of different users can be met.

[0033] The intelligent six-axis servo arm control system 14 is used to control the steering and amplitude of the six axes of the six-axis robot arm 1, so that the end of the six-axis robot arm 1 can accurately move the laser marking machine 8 to the front of the marking position on the surface of the component, which is convenient for subsequent marking operations. The six-axis robot arm 1 is small in size and flexible in adjustment, which can meet the requirements of operations in narrow spaces, high places and other environments, avoiding the need for operators to climb high.

[0034] The end safety distance locking system 15 can be used to preset a safety distance M, and determine whether the distance between the end safety distance locking laser 10 and the surface of the component meets the safety distance M through the receiving and transmitting light beams of the end safety distance locking laser 10, and when it meets the safety distance M, the computer control system 2 is used to trigger the intelligent six-axis servo arm control system 14 to lock the six-axis robot arm 1, making safe preparations for marking.

[0035] Please see attached Figure 3 The laser beam direction of the end safety distance locking laser 10 is perpendicular to the end surface of the laser marking machine 8 and the component surface, ensuring the accurate judgment of the safety distance M, while ensuring that the end surface of the laser marking machine 8 is parallel to the component surface, which facilitates safe and accurate marking operations.

[0036] Please see attached Figure 3The first radar obstacle avoidance and infrared laser transmitting integrated device 6 and the second radar obstacle avoidance and infrared laser transmitting integrated device 7 are symmetrically arranged on the ends of the six-axis robotic arm 1, and form a projection area covering the laser marking position on the surface of the component located above and below (or on the left and right sides) of the laser marking machine 8.

[0037] The first radar obstacle avoidance and infrared laser transmitting integrated device 6 and the second radar obstacle avoidance and infrared laser transmitting integrated device 7 are symmetrically arranged between the six-axis robot arm 1 and the laser marking machine 8 to ensure that the laser marking machine 8 is located in the middle of the projection area.

[0038] Please see attached Figure 4 The engineering identification laser marking device also includes an abnormal feedback system 16, which is electrically connected to the laser marking machine 8 and the laser marking control system 3.

[0039] The abnormal feedback system 16 can be adaptively selected according to the type of the laser marking machine 8, and is used to collect the fault signal of the laser marking machine 8 in real time. After the fault signal is collected, it is fed back to the laser marking control system 3, so that the laser marking control system 3 can adjust the control mode of the laser marking machine 8, such as controlling the laser marking machine 8 to stop running, etc., to ensure timely response of the laser marking machine 8 in abnormal conditions.

[0040] Please see attached Figure 1 and attached Figure 2 A plurality of universal wheels 18 are provided at intervals at the bottom of the base 17 .

[0041] Preferably, the entire device is integrated on the base 17, and the base 17 can adopt a metal frame structure. The universal wheel 18 can adopt a universal wheel with a locking function in the prior art, so that the entire device can be flexibly moved at the work site and locked near the component for marking operations, which is more convenient to use.

[0042] Please see attached Figure 1 To Attachment Figure 4 , the working process and working principle of the utility model are:

[0043] The power supply and power system assembly 4 is started, and the whole device is in operation. The six-axis servo arm control system 14 is used to adjust the six-axis robot arm 1 to be close to the component to be marked, and the end direction of the six-axis robot arm 1 is perpendicular to the surface of the component. At this time, the end safety distance locking laser 10 emits laser to the surface of the component in real time, and the end safety distance locking system 15 is triggered after reaching the safety distance M, so that the six-axis servo arm control system 14 locks the six-axis robot arm 1, and the six-axis robot arm 1 is in a stationary state.

[0044] Red laser is emitted to the surface of the component by the first radar obstacle avoidance and infrared laser emission integrated device 6 and the second radar obstacle avoidance and infrared laser emission integrated device 7 to form a projection area on the surface of the component. The emission angle and projection range of the red laser can be adjusted according to the size and content of the marked text / pattern so that the projection area just covers the position of the entire marked image.

[0045] The required marking content is input through the control screen 5 via the identification input and parameter control system 13, and the end of the six-axis robot arm 1 is controlled by the computer control system 2 via the six-axis servo arm control system 14 to gradually approach the surface of the component. The laser marking control system 3 controls the laser marking machine 8 to automatically mark. After the marking is completed, the laser marking machine 8 returns to the front of the component surface through the six-axis robot arm 1 and maintains a safe distance M.

[0046] During the entire marking process, the laser radar obstacle avoidance control system 11 controls the first radar obstacle avoidance and infrared laser transmitter integrated device 6 and the second radar obstacle avoidance and infrared laser transmitter integrated device 7 to perform real-time detection of interference objects in the marking area of ​​the laser marker 8, ensuring that there are no other objects interfering within the end motion range of the six-axis robotic arm 1, such as protruding flanges, valves, etc., thereby ensuring the safe operation of the laser marker 8.

[0047] During the operation of the laser marking machine 8 , the abnormal feedback system 16 collects fault signals of the laser marking machine 8 in real time. If the laser marking machine 8 has an abnormal operation, the abnormal information can be transmitted to the laser marking control system 3 through the abnormal feedback system 16 .

[0048] Under certain special construction working conditions, the laser marking machine 8 needs to rotate less than 90°. At this time, the laser marking machine can be controlled by the computer control system 2 to fine-tune the rotating shaft 9 to drive the laser marking machine 8 to rotate at a specified angle.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
