DETAILED DESCRIPTION

[0018] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0019] Please refer to Figures 1 to 9 As shown, a laser straight seam welding device of the present invention includes a machine platform 2, a moving mechanism, a plate grabbing mechanism 4, a plate splicing mechanism 9, a plate arranging component and a laser welding machine body 8. The plate splicing mechanism 9 is installed at the lower part of the machine platform 2, and the moving mechanism is installed at the upper part of the machine platform 2. One side of the moving mechanism is drivingly connected to the laser welding machine body 8, and the other side of the moving mechanism is drivingly connected to the plate grabbing mechanism 4. The plate arranging component is arranged on both sides of the plate splicing mechanism 9. Plate flattening mechanisms are also provided on both sides of the plate splicing mechanism 9, and the plate flattening mechanisms are used to flatten the edges of the plates.

[0020] The working principle of the present invention is as follows: during the actual processing of the kettle liner, when the liner plate 20 needs to be welded, the plate can be placed on the machine 2, and then the moving mechanism is operated to drive the plate grabbing mechanism 4 to reach above the plate, and the plate grabbing mechanism 4 is used to grab the plate, and then the moving mechanism drives the plate grabbing mechanism 4 to move, so that the plate grabbing mechanism 4 places the plate into the plate splicing mechanism 9, and the plate is sorted by the plate sorting assembly to avoid plate deviation, and then the plate is spliced ​​by the plate splicing mechanism 9, and the moving mechanism drives the laser welding machine body 8 to weld the plate.

[0021] Furthermore, the moving mechanism includes a linear motor 6, a first mover, a second mover, a first height adjustment mechanism 7 and a second height adjustment mechanism 5. The linear motor 6 is installed on the upper part of the machine platform 2. One side of the linear motor 6 is linearly driven and connected to the first mover. The laser welding machine body 8 is connected to the first mover through the first height adjustment mechanism 7. The other side of the linear motor 6 is linearly driven and connected to the second mover. The plate grabbing mechanism 4 is connected to the second mover through the second height adjustment mechanism 5.

[0022] As can be seen from the above description, when it is necessary to drive the laser welding machine body 8 to move, the linear motor 6 drives the first height adjustment mechanism 7 and the laser welding machine body 8 to move through the first mover, and at the same time adjusts the height of the laser welding machine body 8 through the first height adjustment mechanism 7; When it is necessary to drive the plate grabbing mechanism 4 to move, the linear motor 6 drives the first height adjustment mechanism and the plate grabbing mechanism 4 to move through the second mover, and at the same time adjusts the height of the plate grabbing mechanism 4 through the second height adjustment mechanism 5.

[0023] Furthermore, the plate grasping mechanism 4 includes a first linear drive component 401, a lifting plate 402, a vacuum exhaust component 404 and a suction cup 403. The upper part of the first linear drive component 401 is connected to the second height adjustment mechanism 5, and the lower part of the first linear drive component 401 is linearly driven and connected to the lifting plate 402. The upper surface of the lifting plate 402 is equipped with the vacuum exhaust component 404, and the lower surface of the lifting plate 402 is equipped with several suction cups 403. The suction cups 403 are all connected to the vacuum exhaust component 404 through an air guide tube.

[0024] From the above description, it can be seen that when it is necessary to grab the plate, the first linear drive component 401 can be operated to make the first linear drive component 401 drive the lifting plate 402 to descend, and make the suction cup 403 contact with the plate, and then the vacuum exhaust component 404 can be operated to make the vacuum exhaust component 404 discharge the air in the suction cup 403 through the air guide tube, and grab the plate through the suction cup 403.

[0025] Furthermore, the plate splicing mechanism 9 includes a bidirectional drive component, a slide 901, an angle adjustment component, a second rotating drive member 904, a flip arm 903 and a clamping component. The two sides of the bidirectional drive component are relatively driven and connected to the slide 901, and the slide 901 is installed with an angle adjustment component. One side of the angle adjustment component is provided with the second rotating drive member 904, and the other side of the angle adjustment component is rotatably connected to the flip arm 903. The second rotating drive member 904 is driven and connected to one side of the flip arm 903, and the other side of the flip arm 903 is provided with a material trough, and the clamping component is connected to the material trough.

[0026] From the above description, it can be seen that when it is necessary to splice the plates, the angle adjustment component adjusts the angle of the flip arm 903 according to the style of the plates, and then places the two sides of the plates into a material trough respectively, and runs the clamping component to clamp the plates, and then runs the second rotating drive member 904, so that the second rotating drive member 904 drives the flip arm 903 to flip the plates, and at the same time, the two-way drive component drives the two flip arms 903 closer through the two slides 901, so that the two sides of the plates are close to each other, and then the seams are welded by the laser welding machine body 8.

[0027] Furthermore, the bidirectional drive assembly includes a track platform 909, a slider, a bidirectional screw rod 906, a third rotating drive member 910 and a slide rod 907.

The bidirectional screw rod 906 is rotatably connected to the inside of the track groove. The third rotating drive member 910 is driven and connected to the bidirectional screw rod 906 through a synchronous belt 913. The two sides of the track groove are relatively slidably connected with a slider. The lower part of the slider is engaged with the bidirectional screw rod 906. The upper part of the slider is fixedly connected to one of the slide platforms 901 respectively. A slide rod 907 is provided on both sides of the bidirectional screw rod 906. The slide rod 907 is fixedly connected to the inside of the track groove, and the lower part of the slider is slidably connected to the slide rod 907.

[0028] From the above description, it can be seen that when it is necessary to drive the two flip arms 903 closer, the third rotating drive member 910 can be operated, so that the third rotating drive member 910 drives the bidirectional screw rod 906 to rotate through the synchronous belt 913, and then the bidirectional screw rod 906 drives the sliders on both sides to move relative to each other in the track groove, and at the same time, the slider drives the flip arm 903 closer through the slide 901.

[0029] Furthermore, the angle adjustment assembly includes a fourth rotating drive member 902 and an adjustment platform 905, the lower part of the fourth rotating drive member 902 is detachably connected to the slide 901, the upper part of the fourth rotating drive member 902 is connected to the rotating drive member of the adjustment platform 905, the second rotating drive member 904 is installed on one side of the adjustment platform 905, and the other side of the adjustment platform 905 is rotatably connected to the flip arm 903.

[0030] From the above description, it can be seen that when the angle of the flip arm 903 needs to be adjusted according to the style of the plate, the fourth rotating drive member 902 can be operated to drive the adjustment platform 905 to rotate, and the adjustment platform 905 drives the flip arm 903 to adjust the angle.

[0031] Furthermore, the clamping assembly includes several second linear drive members 912, a splint 911 and an anti-slip pad 908. The splint 911 is movably connected to one side of the material trough, and the anti-slip pad 908 is installed on the other side of the material trough. Several second linear drive members 912 are installed on the outside of the flip arm 903, and the second linear drive members 912 are all linearly driven and connected to the splint 911.

[0032] From the above description, it can be seen that when it is necessary to clamp the plate, several second linear drive members 912 can be operated after the plate enters the material trough, so that the second linear drive members 912 can jointly drive the clamping plate 911 to move, and the plate can be clamped through the mutual cooperation of the clamping plate 911 and the anti-slip pad 908.

[0033] Furthermore, the sheet material sorting assembly includes a mounting frame 15, a third linear drive member 16 and a sorting plate 14.

The third linear drive member 16 is linearly driven and connected to the sorting plate 14.

[0034] From the above description, it can be seen that it is beneficial to operate the third linear drive members 16 on both sides after the plate enters the material trough, so that the third linear drive members 16 drive the sorting plate 14 to sort both sides of the plate.

[0035] Furthermore, the plate flattening mechanism is provided between the flip arm 903 and the finishing plate 14, and the plate flattening mechanism includes a pressing assembly 10 and a supporting assembly 11, wherein the pressing assembly 10 is mounted on the upper portion of the machine 2, and the supporting assembly 11 is mounted on the lower portion of the machine 2; The support assembly 11 includes a fourth linear drive member 1101 and a support platform 1103. The fourth linear drive member 1101 is installed at the lower part of the machine platform 2. The fourth linear drive member 1101 is linearly driven and connected to the support platform 1103. The pressing assembly 10 includes a fifth linear drive component 1003 and a flattening component 1004. The fifth linear drive component 1003 is installed on the upper part of the machine platform 2, and the flattening component 1004 is arranged above the support platform 1103. The fifth linear drive component 1003 is linearly driven and connected to the flattening component 1004.

[0036] From the above description, it can be seen that after the plate is clamped, the fourth linear drive member 1101 can be operated to make the fourth linear drive member 1101 drive the support platform 1103 to rise, and make the support platform 1103 fit the lower surface of the edge of the plate, and then the fifth linear drive member 1003 can be operated to make the fifth linear drive member 1003 drive the flattening member 1004 to descend, and the flattening member 1004 is pressed on the upper surface of the edge of the plate, and at the same time, the edge of the plate is squeezed through the mutual cooperation with the support platform 1103 to make the edge of the plate smoother, which is convenient for subsequent welding of the plate.

[0037] Furthermore, it also includes a supporting assembly, which is provided between the two flip arms 903, and an avoidance groove is provided on the machine 2, and the supporting assembly is connected to the avoidance groove; The supporting assembly includes a mounting platform, a sixth linear drive component 12 and a supporting plate 18.

The supporting plate 18 is arranged above the mounting platform. The sixth linear drive component 12 is linearly driven and connected to the supporting plate 18.

[0038] From the above description, it can be seen that after the plate reaches the material trough, the sixth linear drive member 12 drives the support plate 18 to rise, and supports the middle part of the plate through the support plate 18, so as to avoid the plate bending due to lack of support in the middle part of the plate and ensure the welding of the plate.

[0039] Furthermore, a pusher assembly is provided on one side of the supporting assembly, and a conveying assembly 3 is provided on the other side of the supporting assembly; The pusher assembly includes a seventh linear drive member 17 and a pusher plate 13.

One side of the seventh linear drive member 17 is connected to the machine 2, and the other side of the seventh linear drive member 17 is linearly driven and connected to the pusher plate 13.

[0040] From the above description, it can be seen that it is beneficial to operate the seventh linear drive member 17 after the plate welding is completed, so that the seventh linear drive member 17 drives the push plate 13, and pushes the welded plate to the conveying component 3 through the push plate 13, and sends the plate out through the conveying component 3.

[0041] Furthermore, it also includes a controller, which is electrically connected to the moving mechanism, the plate grabbing mechanism 4, the plate splicing mechanism 9, the plate sorting assembly and the laser welding machine body 8 respectively.
