This technology utilizes a welding laser irradiation unit, facing the welding object, to irradiate the welding target portion of the object with laser light, thereby welding the object. Furthermore, a heating unit, located on the opposite side of the welding laser irradiation unit relative to the object, heats the welding target portion from the opposite side, thereby preheating the welding target portion. However, this patent has the following drawbacks.

However, the laser head is easily damaged due to long-term high-temperature operation, and the internal connection parts of the laser head are complex.

[0014] Technical effects and advantages of the present invention: 1. The present invention uses a self-repair component to synchronously drive the positioning sleeve and the auxiliary sleeve to rotate 180 degrees through the connecting bar, thereby realizing the spatial position exchange of the main laser head and the auxiliary laser head. During this process, the conductive terminal rotates to the docking end position with the main laser head, and the docking end of the auxiliary laser head is precisely rotated to just below the power supply terminal, completing the seamless switching of the power supply interface. A single rotation action is used to realize the coordinated position exchange of the main laser head, the conductive terminal, and the docking end, which not only avoids the error risk of multiple positioning required for traditional disassembly and assembly, but also ensures the rapid access of the auxiliary laser head to the circuit through the 180-degree symmetrical layout. Compared with maintenance by maintenance personnel, the maintenance steps are greatly reduced, and there is no need to remove the shell or adjust the power supply line, which makes the laser head maintenance processing speed faster, meets the needs of efficient production, and realizes intelligent self-repair and efficient processing under existing conditions.

[0015] 2. The present invention adopts a synchronous separation component, which generates magnetic force by driving the electromagnet through the controller, so that the magnetic plate slides down along the inner wall of the linkage bar. In this way, the convex rod and the connecting bar move downward synchronously, realizing the smooth downward movement of the positioning sleeve and the auxiliary sleeve. At the same time, the main laser head drives the conductive terminal and the power supply terminal to be accurately separated vertically under the action of gravity, avoiding contact damage that may be caused by traditional disassembly and assembly. Then the motor is switched to drive the linkage block to rotate 180 degrees, and the linkage bar drives the convex rod and the connecting bar to rotate synchronously, providing space for subsequent laser head switching. The power supply separation and structural pre-rotation are completed through single electromagnetic control and mechanical linkage, simplifying the traditional multi-step disassembly and assembly into two automated actions, significantly improving the maintenance response speed.

[0016] 3. The present invention realizes real-time monitoring and rapid conduction of abnormal current by detecting and separating components and utilizing direct contact between the sensing terminal and the conductive terminal. When the current value is abnormal, the controller immediately starts the contraction electric cylinder, so that the insulating strip drives the sensing terminal and the socket block to move obliquely along the convex strip oblique column. Only a single mechanical action is required to complete the separation of the sensing terminal and the conductive terminal, which avoids the lag of manual detection and realizes the rapid separation operation of the sensing terminal and the conductive terminal through automated intelligent detection, reserves an obstacle-free space for subsequent self-repair operations, and significantly improves the synchronization between the equipment fault response speed and the repair speed.

[0017] In summary, through the interaction of these multiple functions, damage to the main laser head is first detected, the sensing terminals are quickly separated from the conductive terminals, the positioning sleeve and auxiliary sleeve are simultaneously lowered, and the conductive terminals are precisely separated vertically from the power supply terminals. Finally, the docking end of the auxiliary laser head is precisely rotated to directly below the power supply terminal, completing the seamless switching and docking of the power supply interface. Compared to maintenance personnel, this significantly reduces the number of maintenance steps and eliminates the need to remove the casing or adjust the power supply lines, enabling efficient intelligent self-repair.

[0027] 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.

[0028] like Figure 1 - Figure 8A mirror mold steel laser welding device is shown, which is provided with a self-repair component, a synchronous separation component and a detection separation component. The setting of each component first detects damage to the main laser head 5, and at the same time, the sensing terminal 18 is quickly separated from the conductive terminal 4, and at the same time, the positioning sleeve 6 and the auxiliary sleeve 8 are moved downward, and the conductive terminal 4 is precisely separated vertically from the power supply terminal 3. Finally, the docking end 10 of the auxiliary laser head 9 is precisely rotated to the bottom of the power supply terminal 3 to complete the seamless switching and docking of the power supply interface. Compared with maintenance personnel, the maintenance steps are greatly reduced, and there is no need to disassemble the casing or adjust the power supply line, which can realize intelligent self-repair and efficient processing. The specific structural settings of each mechanism and component are as follows.

[0029] In this embodiment, if Figure 1 - Figure 4 As shown, a self-repair component is provided inside the power supply terminal 3, and the self-repair component includes: a plurality of conductive terminals 4, which are respectively slidably connected inside the plurality of power supply terminals 3, the bottom end of the conductive terminal 4 is fixedly connected to the main laser head 5, and the outer wall of the main laser head 5 is slidably connected to the positioning sleeve 6; a linkage bar 7, which is slidably located on the outer wall of the positioning sleeve 6, one end of the linkage bar 7 is slidably connected to the auxiliary sleeve 8, and the inner wall of the auxiliary sleeve 8 is slidably connected to the auxiliary laser head 9, and the upper surface of the auxiliary laser head 9 is fixedly connected to a plurality of docking ends 10, and the inner wall of the linkage bar 7 is provided with a synchronous separation component, which is used to drive the positioning sleeve 6 and the auxiliary sleeve 8 to move downward synchronously, and vertically separate the conductive terminal 4 from the power supply terminal 3; a sensing terminal 18 is slidably connected to one side of the outer wall of each conductive terminal 4, and a detection separation component is provided on the lower inclined surface of the sensing terminal 18, which is used to detect damage to the main laser head 5 and cause the sensing terminal 18 to tilt upward and separate from the conductive terminal 4. The main laser head 5 and the auxiliary laser head 9 are symmetrically arranged about the linkage bar 7, with the top surface of the conductive terminal 4 and the top surface of the docking terminal 10 being on the same horizontal plane. This allows the linkage bar 7 to rotate 180 degrees, causing the protruding bar 11 to drive the connecting bar 12 to rotate 180 degrees. This causes the positioning sleeve 6 to drive the main laser head 5 180 degrees, which in turn drives the conductive terminal 4 180 degrees. Simultaneously, the main laser head 5 drives the conductive terminal 4 180 degrees, and the auxiliary sleeve 8 drives the auxiliary laser head 9 180 degrees. When the docking terminal 10 is located below the power supply terminal 3, the conductive terminal 4 and the docking terminal 10 can be swapped, completing the self-repair docking operation.

[0030] In this embodiment, if Figure 4 - Figure 5As shown, the synchronous separation component includes: a protruding rod 11, which is slidably connected to the inner wall of the linkage bar 7, and the top of the protruding rod 11 is fixedly connected to the connecting bar 12, the positioning sleeve 6 and the auxiliary sleeve 8 are both fixedly connected to the connecting bar 12, and spring plates 13 are provided on both sides of the protruding rod 11, the top of the spring plate 13 is fixedly connected to the connecting bar 12, and the bottom end of the spring plate 13 is fixedly connected to the linkage bar 7; a magnetic plate 14, which is fixedly connected to the bottom end of the protruding rod 11, and the magnetic plate 14 slides along the inside of the linkage bar 7, and a magnet 15 is provided under the magnetic plate 14, and the magnet 15 is fixedly connected to the linkage bar 7; a linkage block 16, which is fixedly connected to the lower surface of the linkage bar 7, and a switching motor 17 is installed on the lower surface of the linkage block 16, and the switching motor 17 is used to drive the linkage block 16 to rotate, and the outer wall of the switching motor 17 is fixedly connected to the outer shell 2, and the magnet 15 and the switching motor 17 are both electrically connected to the controller 29. The two spring pieces 13 are symmetrically arranged about the protruding rod 11. The outer wall of the magnetic plate 14 and the inner wall of the linkage bar 7 are both smooth surfaces. The output end of the switching motor 17 is fixedly connected to the linkage block 16. This allows the magnet 15 to generate a magnetic force to magnetically move the magnetic plate 14 downward. In this way, the magnetic plate 14 is driven by the magnetic force to move the bottom end of the protruding rod 11 downward. The protruding rod 11 will drive the connecting bar 12 downward, and at the same time, the two spring pieces 13 are compressed, causing the positioning sleeve 6 and the auxiliary sleeve 8 to move downward synchronously. The main laser head 5 moves downward under the action of gravity, causing the conductive terminal 4 to be vertically separated from the power supply terminal 3. The switching motor 17 starts to drive the linkage block 16 to rotate 180 degrees. The linkage bar 7 drives the protruding rod 11 to rotate 180 degrees. The protruding rod 11 drives the connecting bar 12 to rotate 180 degrees, realizing a synchronous separation operation and more rapid self-repair processing.

[0031] In this embodiment, if Figure 6 - Figure 7As shown, the detection and separation assembly includes: a harness 19, fixedly connected to the lower inclined surface of the sensing terminal 18. One end of the harness 19 is provided with a current detector 20, which is fixedly connected to the laser main unit 1 and electrically connected to the controller 29; a socket block 21, fixedly connected to the upper inclined surface of the sensing terminal 18. The inner wall of the socket block 21 is slidably penetrated by a protruding oblique column 22, which is used to guide the movement of the socket block 21; an insulating strip 23, fixedly mounted at the top of the sensing terminal 18. The upper inclined surface of the insulating strip 23 is provided with a retracting cylinder 24, which is electrically connected to the controller 29 and the top of the retracting cylinder 24 is fixedly connected to the laser main unit 1. The top of the socket block 21 is fixedly connected to the laser main unit 1, and the outer walls of the socket block 21 and the outer walls of the protruding oblique column 22 are both smooth. So that when the main laser head 5 is damaged, the abnormal current will flow along the conductive terminal 4 to the sensing terminal 18, and then to the wiring harness 19 through the sensing terminal 18. When the current value sensed by the current detector 20 is not within the normal current value range set by the controller 29, the main laser head 5 is damaged, and the retracting end of the retracting electric cylinder 24 will promptly drive the insulating strip 23 to tilt upward, and the sensing terminal 18 will drive the socket block 21 to tilt upward. At the same time, the sensing terminal 18 will drive one end of the wiring harness 19 to tilt upward, so that the sensing terminal 18 will tilt upward and separate from the conductive terminal 4. This can not only detect whether the main laser head 5 is damaged, but also perform the linkage separation operation of the sensing terminal 18 when the main laser head 5 is damaged.

[0032] In this embodiment, if Figure 8 As shown, the outer wall of the laser main unit 1 is fixedly connected to a sleeve plate 25, on the lower inclined surface of which a slide plate 26 is slidably mounted. A support plate 27 is fixedly connected to the lower inclined surface of slide plate 26, and a movable electric cylinder 28 is mounted on one side of slide plate 26. A controller 29 is fixedly mounted on the outer wall of support plate 27, and a positioning plate 30 is fixedly connected to the inner wall of support plate 27. The output end of movable electric cylinder 28 is fixedly connected to one side of sleeve plate 25, and movable electric cylinder 28 is used to move sleeve plate 25. The controller 29 turns on the laser main unit 1, allowing the power supply terminal 3 to supply power to the conductive terminal 4. This allows the main laser head 5 to generate laser light and illuminate the weld area of ​​the mirror-finished mold steel. The output end of movable electric cylinder 28 then moves rightward along slide plate 26. This causes the sleeve plate 25 to move the laser main unit 1 rightward, and the power supply terminal 3 also drives the conductive terminal 4 rightward. This allows the main laser head 5 to move rightward along the weld area of ​​the mirror-finished mold steel, thus achieving mobile laser welding.

[0033] In this embodiment, if Figure 3As shown, a plug cap 31 is provided above the docking end 10, and the plug cap 31 is plugged into the outer shell 2 so that the plug cap 31 can be pulled upward to open the top opening of the outer shell 2, making it convenient to pre-place the auxiliary laser head 9 inside the auxiliary sleeve 8 for positioning operation.

[0034] The working principle of the mirror mold steel laser welding device of the present invention is as follows: First, when welding, the present invention pulls up the plug cap 31, and the plug cap 31 is plugged and separated from the housing 2. Then, the auxiliary laser head 9 is plugged into the inside of the auxiliary sleeve 8, and the auxiliary laser head 9 is pre-placed inside the auxiliary sleeve 8 for positioning. Then, the plug cap 31 is pressed down, and the plug cap 31 is plugged into the inside of the housing 2 for shielding and sealing. Then, the expansion bolts are inserted into the internal holes of the support plate 27 to fix the support plate 27 to the ground base. The mirror mold steel to be welded is placed obliquely on the inner wall of the positioning plate 30. Then, the laser host 1 is turned on by the controller 29, and the laser host 1 supplies power to the two power supply terminals 3. The power supply terminals 3 supply power to the conductive terminals 4, which in turn supplies power to the main laser head 5. The main laser head 5 generates laser light to irradiate the welding part of the mirror mold steel. At the same time, the controller 29 starts the moving electric cylinder 28, and the output end of the moving electric cylinder 28 moves right along the slide 26, so that the output end of the moving electric cylinder 28 pushes the sleeve plate 25 to move right, so that the sleeve plate 25 drives the laser host 1 to move right, the laser host 1 drives the two power supply terminals 3 to move right, the power supply terminals 3 drive the conductive terminals 4 to move right, and the conductive terminals 4 drive the main laser head 5 to move right. The main laser head 5 can move right along the welding part of the mirror mold steel for welding.

[0035] Secondly, when the present invention performs detection and separation, the current detector 20 is supported by the laser host 1, and the sensing terminal 18 contacts the conductive terminal 4. When the main laser head 5 is damaged, the abnormal current is diverted to the conductive terminal 4, and the abnormal current is diverted along the conductive terminal 4 to the sensing terminal 18, and then diverted to the wiring harness 19 through the sensing terminal 18, and then diverted to the current detector 20. When the current value sensed by the current detector 20 is not within the normal current value range set by the controller 29, the main laser head 5 is damaged. The retracting electric cylinder 24 is immediately started through the controller 29. The retracting end of the retracting electric cylinder 24 drives the insulating strip 23 to tilt upward, the insulating strip 23 drives the two sensing terminals 18 to tilt upward, the sensing terminal 18 drives the socket block 21 to tilt upward, the socket block 21 moves tilt downward along the outer wall of the protruding strip oblique column 22, and at the same time, the sensing terminal 18 drives one end of the wiring harness 19 to tilt upward, so that the sensing terminal 18 tilts upward and separates from the conductive terminal 4, so that the sensing terminal 18 will not block the self-repair operation of the conductive terminal 4.

[0036] At the same time, when the present invention performs synchronous separation, the controller 29 supplies power to the magnet 15, which generates a magnetic force to cause the magnetic plate 14 to move downward. The magnetic plate 14 slides downward along the inner wall of the linkage bar 7. At the same time, the magnetic plate 14 drives the bottom end of the protruding rod 11 to move downward, and the outer wall of the protruding rod 11 slides down along the inner guide of the linkage bar 7. The protruding rod 11 drives the connecting bar 12 downward, and the connecting bar 12 squeezes the top ends of the two springs 13, causing the two springs 13 to be compressed. In this way, the connecting bar 12 drives the positioning sleeve 6 and the auxiliary sleeve 8 to move downward synchronously. The connecting bar 12 drives the positioning sleeve 6 downward, and the main laser head 5 moves downward under the action of gravity. In this way, the main laser head 5 drives the conductive terminal 4 downward, and causes the conductive terminal 4 to be vertically separated from the power supply terminal 3, and then the outer wall of the switching motor 17 is supported by the housing 2. The switching motor 17 is started by the controller 29, and the switching motor 17 drives the linkage block 16 to rotate 180 degrees, so that the linkage block 16 drives the linkage bar 7 to rotate 180 degrees, and at the same time the linkage bar 7 drives the protruding rod 11 to rotate 180 degrees, and the protruding rod 11 drives the connecting bar 12 to rotate 180 degrees.

[0037] Finally, when the present invention performs self-repair, the connecting strip 12 will drive the positioning sleeve 6 to rotate one hundred and eighty degrees, and at the same time, the connecting strip 12 drives the sub-sleeve 8 to rotate one hundred and eighty degrees. In this way, the positioning sleeve 6 drives the main laser head 5 to rotate one hundred and eighty degrees, and the main laser head 5 drives the conductive terminal 4 to rotate one hundred and eighty degrees. At the same time, the sub-sleeve 8 drives the sub-laser head 9 to rotate one hundred and eighty degrees, and the sub-laser head 9 drives the docking end 10 to rotate one hundred and eighty degrees. When the docking end 10 is located below the power supply terminal 3 and the conductive terminal 4 is located at the starting point of the docking end 10, the conductive terminal 4 and the docking end 10 are swapped.

[0038] By turning off the magnet 15 through the controller 29, the magnet 15 no longer generates magnetic attraction force on the magnetic plate 14, so that under the action of the rebound restoring force of the spring piece 13, the magnetic plate 14 drives the protruding rod 11 to move upward, and the protruding rod 11 moves upward along the inner wall of the linkage bar 7, and the protruding rod 11 drives the connecting bar 12 to move upward and reset, and the connecting bar 12 drives the auxiliary sleeve 8 to reset and move upward, and the auxiliary sleeve 8 drives the auxiliary laser head 9 to move the docking end 10 upward and reset, and the docking end 10 moves upward and is inserted into the power supply terminal 3 to complete the docking and power on. At the same time, the controller 29 activates the retracting electric cylinder 24, which pushes the insulating strip 23 to tilt downward and reset. In this way, the insulating strip 23 pushes the socket block 21 to tilt downward, and the socket block 21 drives the sensor terminal 18 to tilt downward. The sensor terminal 18 contacts the docking terminal 10. In this way, the laser host 1 is turned on by the controller 29. The laser host 1 supplies power to the power supply terminal 3, which supplies power to the docking terminal 10, and the docking terminal 10 supplies power to the auxiliary laser head 9. The auxiliary laser head 9 can then generate a welding laser and quickly repair the damaged part of the main laser head 5 inside the housing 2. The repair does not require disassembly, and the self-repair efficiency is greatly improved. At the same time, the current detector 20 continues to conduct electricity through the wiring harness 19, and the wiring harness 19 conducts electricity through the sensor terminal 18, and the sensor terminal 18 conducts electricity to the docking terminal 10, so that the current detector 20 continues to detect and process damage to the auxiliary laser head 9. In the intelligent welding system, there is no need to disassemble or wait for professional maintenance personnel to arrive at the site for repair. Intelligent and automated self-repair of the damaged main laser head 5 can be achieved.
