[0033] The beam frame positioning and splicing module 2 is composed of three claw-shaped brackets 21, six movable side blocks 22, two beam brackets 23 and three inclined support shells 24. The claw-shaped brackets 21 are used to combine the movable side blocks 22, the beam brackets 23 and the inclined support shells 24. The three claw-shaped brackets 21 are fixed on the top of the base 1 in a straight line. The longitudinal ends of the claw-shaped brackets 21 are slidably connected to the two movable side blocks 22, so that the movable side blocks 22 can move longitudinally on the outside of the claw-shaped brackets 21 to change the spacing between the two movable side blocks 22, thereby adapting to the connection beams 7 of different width specifications.

The top of the base 1 is connected to two fixing frames 3 in a sliding manner. The two fixing frames 3 are staggered and distributed on both sides of the beam frame positioning and splicing module 2. The bottom of the beam support 23 is fixedly connected to the fixing frame 3. The combined beam support 23 and the movable side block 22 are on the front side of the fixing frame 3.

The bottom of the inclined support shell 24 is fixedly connected to a rotating disk 241, which is rotatably connected to the center position of the claw-shaped support seat 21, so that the inclined support shell 24 can be rotated at the center position of the claw-shaped support seat 21 through the rotating disk 241, and the direction of the inclined support shell 24 is adjusted to ensure that the channel steel 72 is in a suitable inclined state, so that the connecting beam 7, the middle beam 71 and the channel steel 72 can be quickly positioned through the beam frame positioning and splicing module 2.

[0034] The two welding plate supplement modules 5 and the two welding plate docking modules 4 located inside each fixing frame 3 are correspondingly distributed up and down, and the welding plate docking module 4 is composed of a first driving member 41 and a step support block 42. The first driving member 41 is fixedly connected to the surface of the fixing frame 3, and the step support block 42 is fixedly connected to the output end of the first driving member 41, so that the step support block 42 is positioned inside the beam support 23 through the first driving member 41. The step support block 42 is driven by the first driving member 41 to perform vertical lifting operations. The step area on the step support block 42 is used to clamp and fix a part of the edge and corner welding plate 73, and the protruding part of the step support block 42 can effectively clamp the outer edge of the edge and corner welding plate 73 to effectively complete the tightening and positioning operation of the edge and corner welding plate 73.

[0035] The welding plate supplement module 5 is composed of a second driving member 51, a step top material block 52, an edge buckle plate 53 and an elastic member 54. The second driving member 51 is fixedly connected to the top of the fixing frame 3, and the step top material block 52 is fixedly connected to the output end of the second driving member 51. The step top material block 52 is positioned directly above the first driving member 41 through the second driving member 51. The step top material block 52 is driven by the second driving member 51 to perform vertical lifting operations directly above the corresponding step support block 42. The step area on the step top material block 52 is used to clamp and fix another part of the edge and corner welding plate 73. At the same time, the protruding part of the step top material block 52 can also effectively clamp the outer edge of the edge and corner welding plate 73 to effectively complete the tightening and positioning operation of the edge and corner welding plate 73. The step top material block 52 can push the corner welding plate 73 to move downward, so that the corner welding plate 73 is inserted downward into the staggered interval space between the channel steel 72, the connecting beam 7 and the middle beam 71, so as to effectively make up for the inner angle part between the connecting beam 7, the middle beam 71 and the channel steel 72. The edge gusset plate 53 is close to the narrow end of the step top material block 52, and the surface of the edge gusset plate 53 is fixedly connected with a guide plate 531, which is snap-connected inside the narrow end of the step top material block 52 to position the edge gusset plate 53 on the outside of the narrow end of the step top material block 52. The elastic member 54 is fixedly connected inside the narrow end of the step top material block 52, and the top of the elastic member 54 is fixedly connected to the top of the guide plate 531, so that the edge gusset plate 53 is movably arranged on the outside of the narrow end of the step top material block 52 through the elastic member 54. The bottom end of the edge gusset plate 53 is stressed, so that the edge gusset plate 53 can be driven by the deformation of the elastic member 54 to move up and down on the outer side of the narrow end of the step top material block 52 against the surface of the step top material block 52 to adjust the position of the edge gusset plate 53 at the narrow end of the step top material block 52. The edge gusset plate 53 cooperates with the step top material block 52 to effectively clamp and fix the corresponding corner welding plate 73 to control the corner welding plate 73 to stably descend to the inner corner of the beam frame. After the corner welding plate 73 is docked to the end of the channel steel 72, the bottom end of the edge gusset plate 53 abuts against the upper surface of the connecting beam 7 and the middle beam 71, and can no longer move downward. At this time, the second driving member 51 continues to drive downward, the elastic member 54 is compressed, and the edge gusset plate 53 moves upward relative to the corner welding plate 73 to push the corner welding plate 73 out and leave it in the inner corner, which can effectively complete the adjustment and pushing operation of the corner welding plate 73.

[0036] The outer welding plate splicing module 6 is composed of a connecting frame 61, a profiling frame 62 and a steering member 63.

A baffle 621 is fixedly connected to the top of the profiling frame 62, and the baffle 621 plays the role of blocking the outer welding plate 74 from above, so as to effectively constrain the outer welding plate 74 inside the profiling frame 62.

[0037] The beam frame positioning and splicing module 2 fixes the beam frame at the middle position of the top of the base 1. The three claw-shaped brackets 21 cooperate with the two movable side blocks 22 that are movable on the side, and cooperate with the two beam supports 23 on the outer wall of the movable side blocks 22 to clamp the connecting beam 7 and the middle beam 71 from the outside. The channel steel 72 is obliquely placed between the two connecting beams 7 and the two middle beams 71 by the oblique support shell 24 in the middle position, and the beam frame components are quickly aligned and spliced. The welding plate docking module 4 and the welding plate supplementing module 5 respectively position and constrain the two spliced ​​corner welding plates 73, and the outer welding plate 74 is clamped and positioned on the inner side of the profiling frame 62, which can quickly and effectively place, tighten and adjust the alignment of the beam frame components in a regional manner. The two spliced ​​corner welding plates 73 can be controlled by the first driving member 41 and the second driving member 51 after startup, and can be vertically lifted and lowered in sequence, so that the corner welding plates 73 are close to the inner corner part of the beam frame, so as to effectively splice and supplement the inner corner part between the connecting beam 7, the middle beam 71 and the channel steel 72. The automatic welding arm 11 is controlled by the controller 12 to perform welding operations in steps, so that the automatic welding arm 11 completes the welding operations of the corner welding plates 73, the connecting beams 7, the middle beams 71 and the channel steels 72 in batches.

[0038] The outer welding plate 74 rotates with the profiling frame 62 and approaches the inner corner part. The stepped top material block 52 is controlled by the second driving member 51 to descend again to press the outer welding plate 74, so that the outer welding plate 74 escapes from the profiling frame 62 and is spliced ​​from above to the welding area of ​​the connecting beam 7 and the corner welding plate 73. Therefore, this scheme can effectively perform the rapid positioning and splicing and fastening operations of various parts of the beam frame. The automatic welding arm 11 is started to weld the outer welding plate 74, which simplifies the operation process and allows the staff to stably complete the regional placement, adjustment and splicing of various parts of the beam frame, and batch welding operations, so that the fixed-point welding operations of various parts of the beam frame can be completed quickly and stably, improving the welding effect of the automatic welding equipment and improving the welding efficiency.

[0039] The embodiment of the present invention also provides a control method for automated welding equipment, comprising the following steps:

[0042] S3, the second driving member 51 is started, and the stepped top material block 52 and the edge gusset plate 53 push the other part of the corner welding plate 73 down to the corresponding end of the channel steel 72, and the corner welding plate 73 of this part is connected to the remaining area between the connecting beam 7, the middle beam 71 and the channel steel 72, effectively supplementing the inner angle part between the connecting beam 7, the middle beam 71 and the channel steel 72, and the automatic welding arm 11 is restarted to weld the supplementary corner welding plate 73, the connecting beam 7, the middle beam 71 and the channel steel 72;
