Description

Technical Field

[0001] The invention belongs to the technical field of aviation wire manufacturing, and discloses a full-automatic laser marking machine and a marking method for aviation wires. Background Art

[0002] Aerial conductors are special conductors used to support power transmission lines. Traditionally, the marking of aerial conductors is usually done by printing, engraving, etc., but this method has certain disadvantages. With the continuous development of laser technology, laser marking technology has gradually been applied to conductor marking due to its advantages such as high precision, non-contact, and programmable. Laser marking can achieve permanent marking of objects by concentrating the energy of the laser beam to change the surface characteristics of the target object.

[0003] In the prior art, the following deficiencies exist when marking aviation conductors: the printing technology may be affected by environmental factors, resulting in reduced durability and readability of the mark; and the engraving may cause certain damage to the surface of the conductor, affecting the electrical performance and mechanical strength of the conductor. Existing laser marking machines still require certain manual intervention in operation, and there is no fully automatic and efficient marking solution for the special requirements of large-span structures such as aviation conductors, resulting in low work efficiency and unsuitability for large-scale production. Therefore, there is an urgent need for a laser marking machine that can realize automatic marking of aviation conductors to solve the problem of low automation in existing solutions. Summary of the invention

[0004] In view of the problem that there is no laser marking machine for aviation wires in the prior art, the present invention provides a fully automatic laser marking machine and a marking method for aviation wires to solve the problem in the prior art.

[0006] A marking method of an aviation wire fully automatic laser marking machine, the steps are as follows: Step 1: Pass one end of the wire through two upper wire straightening wheels and three lower wire straightening wheels of the wire straightening device, between the incoming wire wheel I and the incoming wire wheel II, the multi-axis displacement platform, between the outgoing wire wheel I and the outgoing wire wheel II, and the rotary encoder, and finally fix it on the take-up frame; Step 2: Adjust the position of the wire; adjust the multi-axis displacement platform to the left, right, front, back, up, and down to make the wire level in the bar hole of the wire tube; Step 3: Adjust the focal length of the galvanometer. After the laser control board and the laser emitting device are powered on, when the measurement result of the laser ranging sensor does not reach the focal length of the galvanometer, the control circuit controls the cooperation of the lifting motor lead screw and the raised nut to drive the platform to move up and down to adjust the focal length of the galvanometer. Step 4: After the industrial computer is started, set the single distance of the wire marking and the residence time of the wire in the strip hole on the touch screen, and set the thresholds of the tension sensor and the rotary encoder; Step 5: The control circuit starts the winding motor, the incoming wire motor and the outgoing wire motor to rotate, driving the wire to move. The tension sensor measures the tension of the wire in real time. When the tension is higher than the set threshold, the speed of the incoming wire motor is adjusted. When the tension is lower than the set threshold, the speed of the outgoing wire motor is adjusted. Step 6: When all components are operating normally, input the marking instructions and marking content through the industrial computer, and the marking work starts. The red positioning laser emitted by the galvanometer reaches the wire in the wire tube hole, and the single distance is marked within the wire transmission dwell time, and then the next marking begins; Step 7: The winding motor winds the marked wire onto the take-up rack.

[0021] Embodiment, step 1, after passing one end of the wire through a wire hole 11-12-41 of the wire straightening device 11-12, it is passed around the lower end of the first lower wire straightening wheel 11-12-3, the upper end of the first upper wire straightening wheel 11-12-2, the lower end of the second lower wire straightening wheel 11-12-3, the upper end of the second upper wire straightening wheel 11-12-2, and the lower end of the third lower wire straightening wheel 11-12-3, and then passes through another wire hole 11-12 of the wire straightening device 11-12 After 2-41, it passes in sequence between the inlet wheel Ⅰ11-6 and the inlet wheel Ⅱ11-7, the wire tube 12-1-2 of the multi-axis displacement platform 12, the wire wheel 12-1-31 of the tension sensor 12-1-3, between the outlet wheel Ⅰ11-8 and the outlet wheel Ⅱ11-9, the wire hole 11-5-21 of a wire column 11-5-2 of the rotary encoder 11-5, the lower end of the spool 11-5-1, the wire hole 11-5-21 of another wire column 11-5-2, and is finally fixed on the take-up frame 3-2; Step 2, adjust the position of the conductor; adjust the multi-axis displacement platform 12 to the left, right, front, back, up and down, so that the conductor is horizontally located in the bar hole II 12-1-21 of the conductor tube 12-1-2; turn the X-axis adjustment knob 12-2-4 counterclockwise or clockwise to drive the marking platform 12-1 to move left and right; turn the Y-axis adjustment knob 12-2-5 counterclockwise or clockwise to drive the marking platform 12-1 to move forward and backward, so that the conductor is horizontally located in the bar hole II 12-1-21 of the conductor tube 12-1-2; the tension sensor 12-1-3 of the marking platform 12-1 is used to measure the tension value of the marked conductor, and adjust the wire-release speed in real time by adjusting the incoming wire motor 11-10 and the outgoing wire motor 11-11 based on the tension value; Step 3, adjust the focal length of the galvanometer; after the laser control board 4 and the laser emitting device 13 are powered on, when the measurement result of the distance sensor 8-3-5 does not reach the focal length of the galvanometer 13-2, the control circuit 5 controls the lifting motor 8-1 to work, and through the cooperation of the lifting motor 8-1 screw rod 8-2 and the raised nut 8-3-4, the platform 8-3-2 is driven to move up and down to adjust the focal length of the galvanometer 13-2. This is the best position for laser marking; Step 4: After the industrial computer 10 is started, the single distance of the wire marking and the dwell time of the wire in the bar hole II 12-1-21 are set by the BslAppSimple software on the touch screen 2-1 connected to the industrial computer 10. The single marking distance is the distance that the laser marking machine marks once during the dwell time of the wire, and the dwell time of the wire is the time required for the laser marking process; the thresholds of the tension sensor 12-1-3 and the rotary encoder 11-5 are set, and the dwell time is the time required for the laser marking process; The threshold of the tension sensor 12-1-3 is the standard value of abnormal tension of the wire caused by abnormalities in the incoming wire motor 11-10 and the outgoing wire motor 11-11. When the tension is higher or lower than this threshold, the speed of the incoming wire motor 11-10 and the outgoing wire motor 11-11 needs to be adjusted; Step 5, the control circuit 5 controls the winding motor 3, the incoming wire motor 11-10 and the outgoing wire motor 11-11 to rotate, and at the same time drives the incoming wire wheel Ⅰ11-6 and the incoming wire wheel Ⅱ11-7 to rotate, the outgoing wire wheel Ⅰ11-8 and the outgoing wire wheel Ⅱ11-9 to rotate, and the take-up frame 3-2 to rotate, so that the wire moves normally in the entire marking task, and the tension sensor 12-1-3 measures the tension of the wire in real time. When the tension is higher than the set threshold, the tension is too large and the speed of the incoming wire motor 11-10 is adjusted. When the tension is lower than the set threshold, the tension is too small and the speed of the outgoing wire motor 11-11 is adjusted; Step 6: When all components are operating normally, input the marking instruction and marking content through the industrial computer 10, and the marking work starts. The red positioning laser emitted by the galvanometer 13-2 reaches the wire in the hole II 12-1-21 of the wire tube 12-1-2, and completes the single distance within the wire transmission dwell time, and enters the next marking; Step seven, the winding motor 3 winds the marked wire in circles on the take-up frame 3-2. As the number of winding circles increases, the winding speed of the winding motor 3 will slow down. When the distance of the marked wire measured by the rotary encoder 11-5 reaches a certain set value, the speed of the winding motor 3 will increase. The rotary encoder 11-5 measures whether the length of the marked wire reaches the set total length. If not, the marking work continues. If it reaches the maximum value, the control circuit 5 sends a command, the wire stops running, the galvanometer 13-2 stops working, and the marking work is completed.
