[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0038] See also Figures 1-6The present embodiment provides a welding mechanism with an intelligent welding platform, including a welding table 1, the top of the welding table 1 is fixedly connected to a top plate 11 through a support column, and a welding hand 12 is slidably arranged on the top plate 11; it also includes two groups of clamping members arranged on the welding table 1 and a bending member arranged on the clamping member, and the clamping member is driven to move up and down by the movement of the welding table 1. During the up and down movement of the clamping member, the bending member is passively driven to rotate; it also includes a limit assembly to limit the workpiece in the clamping member. When the welding hand 12 moves toward a group of clamping members, the corresponding clamping member is driven to move downward and the bending member is driven to bend the workpiece for welding the workpiece, and at the same time, the other group of clamping members is driven to move upward to unlock the limit assembly for loading the workpiece.

[0039] In an embodiment further provided by the present invention, the clamping member includes a first screw 21 threadedly connected to the welding table 1 and a connecting rod 22 slidably arranged in the welding table 1, and the top ends of the first screw 21 and the connecting rod 22 are rotatably connected to a U-shaped plate 24, and the bottom of the U-shaped plate 24 connected to the first screw 21 is fixedly connected to a fixed rod slidably connected to the welding table 1, and the fixed rod limits the U-shaped plate 24. When the first screw 21 rotates, the U-shaped plate 24 does not rotate therewith, and the bottom ends of the first screw 21 and the connecting rod 22 are rotatably connected to a connecting plate 23, and the two connecting plates 23 are rotatably connected.

[0040] The present invention further provides an embodiment of the bending part, which includes a telescopic rod 31 rotatably arranged on the welding table 1, the top of the telescopic rod 31 is fixedly connected to the limit plate 32, and a support spring 33 is provided on the outer sleeve of the telescopic rod 31. By moving the U-shaped plate 24 downward, the workpiece is driven to move downward and the limit plate 32 is pressed downward synchronously, so that the support spring 33 is compressed. When the limit assembly unlocks the U-shaped plate 24, the limit plate 32 is pushed upward by the elasticity of the support spring 33, and the workpiece is pushed out of the U-shaped plate 24 to realize the blanking function. The telescopic rod 31 is fixedly connected to the outside of the guide plate 36, and the guide plate 36 is sleeved outside the connecting rod 22. 1 is provided with an arc groove for guiding the connecting rod 22 when it rotates with the telescopic rod 31 as the center of the circle. The second gear 35 is fixedly connected to the outside of the first screw 21, and the bottom end of the telescopic rod 31 is fixedly connected to the first gear 34 that meshes with the second gear 35. The first screw 21 rotates in the welding table 1, so that the first screw 21 rotates and moves. When the first gear 34 is engaged with the second gear 35, the second gear 35 drives the first gear 34 to rotate 90°, so that the guide plate 36 drives the connecting rod 22 to rotate, thereby realizing the bending of the workpiece. When the workpiece is bent, the second gear 35 moves out of the first gear 34.

[0041] In the embodiment provided by the present invention, the limiting assembly includes a limiting plate 41 slidably arranged in a U-shaped plate 24 connected to the first screw 21, an L-shaped rod 43 is fixedly connected to the U-shaped plate 24, a round rod 44 fixedly connected to the limiting plate 41 is slidably arranged in the L-shaped rod 43, a return spring 45 is provided on the outer sleeve of the round rod 44, a wedge plate 42 is slidably arranged in the U-shaped plate 24, the wedge plate 42 is slidably arranged in the limiting plate 41, a groove is provided in the wedge plate 42, and the groove is adapted to the wedge surface of the wedge plate 42. When the wedge plate 42 moves, the limiting plate 41 is driven to move in the U-shaped plate 24, thereby facilitating the assembly of the workpiece.

[0042] Specifically, a fixed plate 46 is fixedly connected to the welding table 1, and the fixed plate 46 is adapted to the wedge plate 42. When the welding hand 12 moves to one side, the U-shaped rod in the opposite direction will move upward. When the wedge plate 42 moves upward and contacts the fixed plate 46, it continues to move upward, pushing the limit plate 41 to move into the U-shaped rod, thereby unlocking the limit plate 41.

[0043] The solution further provided by the present invention also includes an unlocking member. After the welding of the workpiece is completed, the unlocking member is driven by the movement of the welding hand 12 to unlock the limit assembly. The unlocking member includes a rotating rod 51 rotatably set on the welding table 1, and the end of the rotating rod 51 is fixedly connected to a rectangular plate 52. A wedge block 53 is slidably set in the rectangular plate 52. The wedge block 53 is adapted to the wedge plate 42. The bottom end of the wedge plate 42 is L-shaped. When the wedge block 53 moves to above the wedge plate 42, the wedge plate 42 is limited to assist in the movement of the limit plate 41. A limit spring 54 is fixedly connected to the rectangular plate 52, and the limit spring 54 is fixedly connected to the wedge block 53.

[0044] Furthermore, a limit block 55 is fixedly connected to the rectangular plate 52, a driving block 56 adapted to the limit block 55 is fixedly connected to the outside of the first screw 21, a torsion spring 57 is provided on the outer sleeve of the rotating rod 51, and both ends of the torsion spring 57 are fixedly connected to the welding table 1 and the rectangular plate 52 respectively.

[0045] In the present invention, a driving member is also included for driving the movement of the welding hand 12. The driving member includes a motor 61. The output end of the motor 61 is fixedly connected to a second screw 62. The second screw 62 is threadedly connected to the welding hand 12. A guide rod 63 is slidingly provided inside the welding hand 12. The guide rod 63 is fixedly connected to the top plate 11.

[0046] Furthermore, it also includes a connecting member for connecting the driving member and the clamping member, the connecting member includes a driving rod 71 rotatably arranged in the welding table 1, the top end of the driving rod 71 is fixedly connected to the driven bevel gear 75, the second screw 62 is fixedly connected to the outside of the driving bevel gear 76 adapted to the driven bevel gear 75, a rectangular rod 72 is slidably arranged in the first screw 21, the first screw 21 is adapted to the rectangular rod 72, when the rectangular rod 72 rotates, the first screw 21 is driven to rotate synchronously, the rectangular rod 72 extends to the outside of the first screw 21 and is fixedly connected to the third gear 73, and the fourth gear 74 adapted to the third gear 73 is fixedly connected to the outside of the driving rod 71.

[0047] During welding, the workpiece is placed in the U-shaped plate 24, and the driving motor 61 drives the second screw 62 to rotate, so that the welding hand 12 moves to the right (with Figure 1 As a reference), at the same time, the second screw 62 rotates to make the active bevel gear 76 drive the driven bevel gear 75 to rotate, thereby making the driving rod 71 drive the fourth gear 74 to rotate, making the third gear 73 rotate, driving the rectangular rod 72 to rotate synchronously, thereby making the first screw 21 on the left rotate and move upward, driving the connecting rod 22 to move upward synchronously through the connecting plate 23, and driving the two U-shaped plates 24 to move upward synchronously. When the wedge plate 42 moves and contacts the fixed plate 46, the U-shaped plate 24 continues to move upward, making the wedge plate 42 move downward in the U-shaped plate 24, thereby pushing the limit plate 41 to move into the U-shaped plate 24, causing the return spring 45 to compress, thereby opening the U-shaped plate 24 and placing the unwelded workpiece into the U-shaped plate 24;

[0048] When the welding hand 12 moves to the right, the first screw rod 21 on the right side rotates and moves downward in the welding table 1, thereby driving the connecting rod 22 to move downward synchronously through the connecting plate 23, causing the second gear 35 to move downward synchronously. When the second gear 35 moves down to engage with the first gear 34, the second gear 35 rotates and drives the first gear 34 to rotate synchronously, thereby driving the telescopic tube to rotate, causing the guide plate 36 to rotate and drive the connecting rod 22 to rotate 90°. At this time, the second gear 35 moves out of the first gear 34, realizing the bending of the workpiece;

[0049] Then the first screw rod 21 continues to move downward, so that the workpiece contacts the limit plate 32 and moves downward, causing the support spring 33 to be compressed. At the same time, the U-shaped plate 24 drives the wedge plate 42 to move downward and contact the wedge block 53. Then the wedge plate 42 continues to move downward, pushing the wedge block 53 away from the wedge block 53, driving the limit spring 54 to be compressed, so that the wedge plate 42 moves down to the bottom of the wedge block 53. Then, the limit spring 54 pushes the wedge block 53 to move above the wedge plate 42. At this time, the welding hand 12 moves to the far right, and then the motor 61 is turned off. The welding hand 12 is used to weld the bent part of the workpiece.

[0050] After welding is completed, the motor 61 is started to rotate in the reverse direction, so that the welding hand 12 moves to the left, and at the same time, the first screw 21 on the right rotates in the reverse direction and moves upward. Figure 5 As shown in FIG. 2 ), when the U-shaped plate 24 moves upward, the wedge block 53 is restricted, causing the wedge plate 42 to move downward within the U-shaped plate 24 , thereby pushing the limit plate 41 out of the U-shaped plate 24 . The support spring 33 pushes the limit plate 32 upward to push the welded workpiece out of the U-shaped plate 24 .

[0051] The first screw rod 21 continues to move upward, driving the driving block 56 to move upward and rotate. When the driving block 56 contacts the limit block 55, it pushes the limit block 55 to rotate, thereby moving the wedge block 53 out of the wedge plate 42, causing the wedge plate 42 to move upward and return to its original position. After the driving block 56 moves out of the limit block 55, the elastic force of the torsion spring 57 pushes the wedge block 53 to return to its original position.

[0052] When the second gear 35 moves up and engages with the first gear 34, the second gear 35 rotates to drive the first gear 34 to rotate, so that the connecting rod 22 rotates to a horizontal state, and then continues to move up until it contacts the fixed plate 46, opens the limit plate 41, and places the new workpiece into the U-shaped plate 24. Similarly, repeat the above operation, so that the welding hand 12 bends and welds the workpiece on the left.

[0053] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
