At the same time, the connecting block 76 is driven to move under the connection of the rotating block five 77. At this time, the connecting block 76 is pulled by the first rotating rod 74 to flip the through-core plate 718 from a horizontal state to a vertical state, and the side plate and the rear cover plate also rotate accordingly. Then, it is only necessary to start the first motor 717 to make the through-core plate 718 continue to flip from a vertical state to a horizontal state. At this time, the side plate and the rear cover plate are flipped to the bottom of the through-core plate 718.

With the cooperation of the welding mechanism 8, it is convenient to weld the inner and outer sides of the joints of the side panel and the rear cover. When the side panel and the rear cover are flipped over and ready for outer side welding, the gravity of the rear cover itself can be used to detect whether the rear cover after inner side welding will fall off the side panel, so as to judge whether the inner welding is reliable.

[0030] In this embodiment, the welding mechanism 8 includes a first threaded rod 81 and a slide rod 82. Both ends of the first threaded rod 81 are fixedly connected to a rotating shaft 1. The outer side of the rotating shaft 1 is rotatably connected to a second fixed block 83. The lower end of the second fixed block 83 is fixedly connected to the second bottom plate 6. The upper end of the second bottom plate 6 is provided with a second motor 84. The output end of the second motor 84 is fixedly connected to the rotating shaft 1.

The first threaded rod 81 and the outer side of the slide rod 82 are movably connected to a moving box 86. The inner side of the moving box 86 is provided with an opening 1 87 and an opening 2 88. The opening 1 87 and the opening 2 88 are connected to each other. 8 are interlinked, a second threaded rod 810 is provided on the inner side of the opening 1 87, the front and rear ends of the second threaded rod 810 are fixedly connected with the rotating shaft 2, the rotating shaft 2 is rotatably connected to the moving box 86, a third motor 89 is installed on the outer side of the moving box 86, the output end of the third motor 89 is fixedly connected to the rotating shaft 2, a moving block 811 is threadedly connected to the outer side of the second threaded rod 810, the other side of the moving block 811 is fixedly connected with the sliding rod 2 812, the sliding rod 812 is slidably connected to the inner side of the opening 2 88, a fourth motor 813 is provided on the upper end of the moving block 811, the output end of the fourth motor 813 is fixedly connected with the multi-stage electric push rod 814, and the output end of the multi-stage electric push rod 814 is provided with a welding gun 815.

[0031] Specifically, the second motor 84 is started to rotate the first threaded rod 81, and the movable box 86 with the welding gun 815 is moved to the bottom of the side panel under the action of the screw principle. The multi-stage electric push rod 814 is started to move the welding gun 815 upward to the junction of the side panel and the inner side of the rear cover. Then the third motor 89 is started to rotate the second threaded rod 810, and the movable block 811 continues to weld with the welding gun 815 from front to back at the junction of the inner side of the side panel and the rear cover through the screw principle. Under the basic operation of this principle, the welding mechanism 8 enables the welding gun 815 to move along the inner and outer sides of the side panel to complete the inner and outer welding of the side panel and the rear cover.

[0032] When in use, under the output of the first cylinder 54, the first connecting rod 510 and the second connecting rod 513 are first placed in a state perpendicular to the ground, the rear cover is placed on the upper end of the storage table 2, and the rear cover is placed between the multiple groups of enclosures 4, and then the side panels are placed in the connecting grooves opened on the core plate 718, and then the splicing operation of the rear cover and the side panels is started, and the first cylinder 54 is started to shrink the output end of the first cylinder 54. When the output end of the first cylinder 54 shrinks, the first fixed rod 57 can be pulled to rotate around the rotating block 2 58 through the connection between the second swivel 55 and the rotating block 1 56. At the same time, under the rotation connection of the second fixed rod 59 and the mounting block 511, the first connecting rod 510 and the second connecting rod 513 are pulled together toward the storage table 2. The direction is flipped. At this time, the connection through the connecting plate 514 will drive the support rod 515 and the movable plate 518 to move toward the upper end of the storage platform 2. During the transfer process, the movable plate 518 is rotatably connected with the support rod 515 under the action of the third rotating ring 516, and through its own gravity, the single-stage electric push rod 1 519 and the first clamping plate 520 are always facing downward, and when the first connecting rod 510 is flipped toward the direction of the storage platform 2 to be parallel to the ground, the movable plate 518 moves to the upper end of the rear cover plate, and the first clamping plate 520 moves to one side of the rear cover plate, and then the single-stage electric push rod 1 519 is started to push the first clamping plate 520 to move toward the rear cover plate, and under the joint clamping of multiple groups of first clamping plates 520, the rear cover plate is fixed to the lower end of the movable plate 518. , then start the first cylinder 54 so that its output end pushes the first fixing rod 57 to rotate, and the first fixing rod 57 is subjected to the thrust to rotate around the rotating block 2 58 in the direction of the core plate 718. During the process, the second fixing rod 59 is connected with the mounting block 511, and the first connecting rod 510 and the second connecting rod 513 are driven to flip in the direction of the core plate 718. After the first connecting rod 510 flips in the direction of the core plate 718 to be parallel to the ground, the moving plate 518 brings the rear cover plate to press on the upper end of the side plate, and the first clamping plate 520 is also on the outside of the side plate at the same time. Then, start the single-stage electric push rod 2 719 to make the second clamping plate 720 clamp the side plate, and then the welding of the inner side of the junction of the rear cover plate and the side plate can be carried out. By starting the second The second motor 84 rotates the first threaded rod 81, and under the action of the screw principle, the movable box 86 moves with the welding gun 815 to the bottom of the side plate, and by starting the multi-stage electric push rod 814, the welding gun 815 moves upward to the inner connection between the side plate and the rear cover plate, and then the third motor 89 is started to rotate the second threaded rod 810, and the movable block 811 continues to weld with the welding gun 815 from front to back at the inner connection between the side plate and the rear cover plate through the screw principle. Under the basic operation of this principle, the welding mechanism 8 moves the welding gun 815 along the inner side of the side plate to complete the inner welding of the side plate and the rear cover plate. When it is necessary to weld the outer connection between the side plate and the rear cover plate, the movable plate 518 is transferred to the upper end of the storage table 2, and then the second cylinder 713 is started.Under the connection between the fifth rotating ring 714 and the fourth extension plate 716, the second rotating rod 78 is pushed to rotate upward around the rotating block 6 79, and the connecting block 76 is driven to move under the connection of the rotating block 5 77. At this time, the first rotating rod 74 pulls the connecting block 76 to flip the core plate 718 from the horizontal to the vertical state, and the side plate and the rear cover plate also rotate accordingly. Then, it is only necessary to start the first motor 717 to make the core plate 718 continue to flip from the vertical to the horizontal state. At this time, the side plate and the rear cover plate are located below the core plate 718, and then it is only necessary to continue to input instructions to the second motor 84 and the third motor 89, so that the welding gun 815 can weld around the outer joint of the side plate and the rear cover plate.
