[0029] It also includes a power unit, a support rod 5, a multi-axis robot arm 6, a laser generator 7 and a protective member 8; the bridge frame 2 is connected to the power unit; the power unit is connected to two support rods 5 distributed on the left and right; the power unit is used to drive the support rods 5 to move horizontally; the base 1 is equipped with a multi-axis robot arm 6; the multi-axis robot arm 6 is equipped with a laser generator 7; the laser generator 7 is connected to the protective member 8, and the protective member 8 is provided with a visual sensor; the protective member 8 is used to protect the weld during laser welding; a laser head 7001 is provided at the lower part of the laser generator 7; a slag blowing groove 8001 is opened on the protective member 8; the laser head 7001 is located above the slag blowing groove 8001.

[0030] The power unit includes an electric slide rail 3 and an electric slider 4; the electric slide rail 3 is installed on the upper front side of the bridge frame 2; two electric sliders 4 distributed left and right are slidably connected to the electric slide rail 3; each electric slider 4 is fixedly connected to a support rod 5.

[0031] The protective member 8 is L-shaped. When in contact with the power distribution cabinet body 001, the corners of the protective member 8 correspond to the corners of the power distribution cabinet body 001 and they do not contact each other.

[0032] It also includes a conduit 9; two front-to-back symmetrical L-shaped connecting grooves 8002 are opened in the protective member 8; two air jets 8003 are opened on the protective member 8; each connecting groove 8002 is connected to the corresponding air jet 8003; the upper and lower parts of the two connecting grooves 8002 are connected to each other through a cavity, and the cavity is connected to the conduit 9.

[0033] The two air jets 8003 are arranged perpendicular to each other.

[0034] The air jets 8003 are all provided with detachable heat-resistant protective nets.

[0035] It also includes a ball 10; a plurality of balls 10 are installed on the protective member 8, which are used to contact with the outer surface of the distribution cabinet body 001 to reduce friction.

[0036] The working steps of the above embodiment are:

[0037] This device is installed in the assembly line of a large-scale production workshop of distribution cabinets for use. First, the distribution cabinet body 001 that has been simply spot-welded is transported through an external conveyor belt. At this time, the distribution cabinet body 001 is not installed with a back panel. When the distribution cabinet body 001 moves to the front of this device, the distribution cabinet body 001 is removed from the external conveyor belt by an external manipulator and is put on two support rods 5. The two support rods 5 jointly support the distribution cabinet body 001, and the two electric sliders 4 are controlled to move away from each other, so that the support rods 5 move away from each other until the two support rods 5 respectively contact the inner left wall and the inner right wall of the distribution cabinet body 001. At this time, the inner side of the distribution cabinet body 001 is supported by the two support rods 5, thereby achieving the fixation of the distribution cabinet body 001.

[0038] Then, under the condition that the switch cabinet body 001 is fixed, the two electric slide blocks 4 are controlled to move together on the electric slide rail 3. Under the monitoring of the visual sensor on the protective member 8, when the edge of the position to be welded of the switch cabinet body 001 is located below the laser generator 7, the electric slide block 4 stops moving, and the multi-axis robot arm 6 is controlled to start. The multi-axis robot arm 6 drives the laser generator 7 and the corresponding parts thereon to move toward the switch cabinet body 001. The ball bearings 10 on the protective member 8 contact the outer surface of the switch cabinet body 001, and the external protective gas tank is connected to the conduit 9. The protective gas is sent to the upper connection through the conduit 9. Through groove 8002, and then the protective gas is ejected from two vertically arranged air jets 8003 to blow away the dust and impurities at the weld, and then the laser generator 7 is controlled to start, and the laser head 7001 emits high-energy laser to weld the weld. At this time, nitrogen can be used as a protective gas for welding the stainless steel distribution cabinet body 001. Nitrogen not only protects the welding position, but also the nitride produced by the chemical reaction between nitrogen and stainless steel can improve the strength of the weld joint, which is beneficial to improving the mechanical properties of the weld, and the weak electrical capacity of nitrogen reduces the formation of plasma cloud, effectively increasing the effective utilization rate of the laser.

[0039] During the welding process, the welding slag splashed at the weld is blown away by the shielding gas blown out perpendicularly to each other. A large amount of welding slag is blown away from the welding position through the slag blowing groove 8001 close to the welding position, so as to cool the welding slag and clean the weld position. The small amount of residual welding slag splashed to a place far away from the welding position and not passing through the slag blowing groove 8001 is blown to the inner wall of the protective part 8 under the blowing of the shielding gas perpendicular to each other, where it adheres to and is cooled, so as to prevent the welding slag from falling on the weld and affecting the welding quality. Subsequently, it is only necessary to simply scrape and clean the inner wall of the protective part 8 to remove the small amount of welding slag attached thereto. Then, it is only necessary to control the multi-axis robot arm 6 so that the protective part 8 moves forward on the surface of the distribution cabinet body 001 through the ball 10 to complete the welding of the edge of the distribution cabinet body 001.

[0040] It is also taken into consideration that due to the differences in the processing technology of the distribution cabinet body 001, if it is necessary to weld the right edge of the distribution cabinet body 001, the two support rods 5 are controlled to move towards each other so that the support rods 5 no longer support the two sides of the inner wall of the distribution cabinet body 001. Then the external manipulator clamps and rotates the distribution cabinet body 001 90° clockwise from the front to the back, so that the original right edge is rotated to the left, and then the welding of the other side of the distribution cabinet body 001 can be started. Through the above work, the welding of the distribution cabinet body 001 is completed.

[0041] Second embodiment

[0042] On the basis of the first embodiment, according to Figure 1-Figure 6As shown, it also includes a rotating unit; the laser generator 7 is connected to the rotating unit; the rotating unit is connected to the protective member 8; the rotating unit is connected to the catheter 9; the rotating unit includes a motor 101, a gear 102, a swivel 103, an outer gear ring 104 and a linkage frame 105; the laser generator 7 is equipped with a motor 101; the output shaft of the motor 101 is fixedly connected to the gear 102; the laser generator 7 is rotatably connected to the swivel 103; the outer ring surface of the swivel 103 is fixedly connected to the outer gear ring 104; the outer gear ring 104 is meshed with the gear 102; the lower part of the swivel 103 is fixedly connected to the linkage frame 105; the linkage frame 105 is connected to the protective member 8; the linkage frame 105 is connected to the catheter 9.

[0043] It also includes an electric actuator 106; two electric actuators 106 distributed front and back are installed at the lower part of the linkage frame 105; the electric actuator 106 is an electric push rod; all the telescopic parts of the electric actuator 106 are bolted to the protective member 8; the protective member 8 is slidably connected to the fixed parts of all the electric actuators 106.

[0044] The two supporting rods 5 are provided with elastic anti-skid layers 5001 on the facing sides thereof, and the remaining side surfaces of the supporting rods 5 are provided with a plurality of grooves for air flow and heat dissipation.

[0045] The working steps of the above embodiment are:

[0046] On the basis of the first embodiment, if it is necessary to switch the welding position of the distribution cabinet body 001, a swivel 103 is added to the laser generator 7, and the motor 101 is controlled to start. The output shaft of the motor 101 rotates, so that the swivel 103 rotates, and the protective member 8 rotates synchronously. Looking from top to bottom, the protective member 8 rotates counterclockwise. When the linkage frame 105 rotates to the rear of the laser head 7001, the opening of the protective member 8 faces the rear, and then the two electric sliders 4 are controlled to move to the left together. When the distribution cabinet body 001 moves to the bottom of the laser generator 7 When the multi-axis robot arm 6 is controlled to start, the protective part 8 is pressed down until the upper ball 10 contacts the surface of the distribution cabinet body 001, and then the electric actuator 106 is controlled to contract, so that the lower ball 10 also contacts the surface of the distribution cabinet body 001, and then the laser generator 7 welds the distribution cabinet body 001, and the shielding gas is injected into the connecting groove 8002 through the conduit 9, and then ejected from the air jet 8003 to protect the welding position, and at the same time, the distribution cabinet body 001 is controlled to continue to move to the left to realize the welding of the long side of the distribution cabinet body 001.

[0047] After completing the welding of the long side of the distribution cabinet body 001, the protective member 8 is located on the right side of the distribution cabinet body 001. At this time, the starting motor 101 is controlled to make the protective member 8 continue to rotate counterclockwise by 90°. At this time, the protective member 8 is symmetrical with the initial position of the protective member 8. At this time, the multi-axis robot 6 and the electric actuator 106 cooperate to make the ball 10 on the protective member 8 contact the right part of the distribution cabinet body 001. At this time, the laser generator 7 is controlled to weld the distribution cabinet body 001. Then, it is only necessary to flip the distribution cabinet body 001 180° with the cooperation of the external robot. The visual sensor on the protective member 8 can monitor the position that needs to be welded, thereby avoiding the structural limitation of the L-shaped protective member 8 in the second embodiment, so that the distribution cabinet body 001 needs to be rotated multiple times to complete the welding of the distribution cabinet body 001, thereby greatly improving the processing efficiency of the distribution cabinet body 001.

[0048] And considering that, based on the above work, Figure 3 As shown, the front vertical edge of the distribution cabinet body 001 also needs to be welded. At this time, the external manipulator removes the distribution cabinet body 001 and rotates the distribution cabinet body 001. Looking from left to right, the distribution cabinet body 001 rotates counterclockwise 90° so that the two sides that have not been welded are facing upward. At this time, the two support rods 5 are controlled to separate, and the distribution cabinet body 001 is placed between the two support rods 5. Then the two support rods 5 are controlled to be close to each other and the distribution cabinet body 001 is clamped. The elastic anti-slip layer 5001 on the support rods 5 is used to prevent the support rods 5 from squeezing and deforming the distribution cabinet body 001, and the distribution cabinet body 001 falls off during welding, affecting the welding quality. Then, according to the above welding operation process, the remaining two sides can be welded.

[0049] According to the above work, the distribution cabinet body 001 with the back plate installed can also be welded by clamping and fixing the anti-slip layer 5001 of the two support rods 5; on the other hand, by customizing the shape of the protective part 8 and programming and debugging by technicians, the device can also be adapted to the automated welding operations of more regular products.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
