[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] For example 1, please refer to Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4As shown, a large sheet metal welding device with automatic flipping function includes four support legs 1, the upper ends of the four support legs 1 are fixedly connected to a support assembly 2, the left side of the upper end of the support assembly 2 is fixedly connected to a welding assembly 6, the middle part of the upper end of the support assembly 2 is fixedly connected to a pre-treatment assembly 5, the right side of the front end of the support assembly 2 is fixedly connected to a console 3, the right side of the upper end of the support assembly 2 is fixedly connected to a flip assembly 4, the support assembly 2 includes a shell 21, a groove 24 is opened in the middle of the upper end of the shell 21, an electric telescopic rod 22 is fixedly connected to the right side of the inner cavity of the groove 24, and the output end of the electric telescopic rod 22 is fixedly connected to It is connected to a rack 1 23, and two symmetrically arranged U-shaped racks 25 are fixedly connected to the right side of the upper end of the shell 21. Two grooves 27 are provided on the side where the two U-shaped racks 25 are close to each other, and two symmetrically arranged grooves 3 28 are provided on the side where the two grooves 27 are close to each other. An initial platform 26 is fixedly connected to the right side of the upper end of the shell 21, and a transmission assembly 29 is rotatably connected to the inner cavity of the support leg 1. The welding assembly 6 includes a base 61, and the bottom end of the base 61 is fixedly connected to the left side of the upper end of the shell 21. A welding arm 62 is fixedly connected to the upper end of the base 61, and a welding head 63 is rotatably connected to the output end of the welding arm 62.

[0035] During the implementation of this embodiment, the workpiece to be welded is first placed on the upper end of the initial table 26, and then the operator needs to adjust the internal parameters of the console 3 according to actual conditions. Then the flip assembly 4 will move to the right and clamp the welded workpiece. Then, the transmission assembly 29 installed inside the shell 21 will be started and drive the welded workpiece to move to the left. During the movement, the U-shaped racks 25 fixedly installed on the front and rear sides of the flip assembly 4 will flip the welded workpiece. After flipping to a specific angle, the flip assembly 4 will drive the welded workpiece to continue to move to the left. When the flip assembly 4 transports the welded workpiece to the specified position, the pretreatment assembly 5 will grind and clean the welded workpiece. Then, the flip assembly 4 will disengage from the clamping of the welded workpiece, and the components inside the flip assembly 4 will continue to move the welded workpiece until welding is completed. When the angle needs to be adjusted after welding is completed, it is only necessary to start the electric telescopic rod 22 through the console 3. When the electric telescopic rod 22 is started, it will push the rack 1 23, so that the welded workpiece rotates, and then it is pushed to the welding position of the welding head 63 again until welding is completed.

[0036] When the welding of the workpiece is completed, the welded workpiece will be returned by the flip assembly 4 along the original path, and then the operator only needs to take the welded workpiece and place a new welded workpiece;

[0037] It should be further noted that the console 3 is a conventional technical means in the prior art. In this solution, only its control function is utilized, and its working principle and line connection are not elaborated in detail here.

[0038] The welding head 63 mentioned above is a conventional technical means in the prior art. In this solution, it is only used to be controlled by the control console 3 to weld the workpiece. Its working principle and circuit connection will not be elaborated in detail here.

[0039] By arranging the turning component 4 to cooperate with the transmission component 29, accurate turning and movement of the welding workpiece can be achieved; by arranging the console 3 to cooperate with the electric telescopic rod 22, accurate adjustment of the angle of the welding workpiece can be achieved; by arranging the pretreatment component 5 to cooperate with the turning component 4, grinding and cleaning of the welding workpiece can be achieved, thereby improving welding accuracy and efficiency, simplifying the operation process, and reducing manual intervention.

[0041] During the implementation of this embodiment, the bidirectional motor 291 will be started under the control of the console 3, and then drive the connecting rod 1 292 to rotate. During the rotation of the connecting rod 1 292, the transmission wheel 293 and the two transmission belts 294 fixed to its outer surface rotate. When the transmission wheel 293 and the two transmission belts 294 rotate, the transmission rope 295 wound around their outer surfaces will drive the corresponding moving assembly 41 to clamp and transport the welded workpiece. Subsequently, when transported to the designated position, the two moving assemblies 41 will disengage from the clamping of the welded workpiece, and then be driven to move by the assembly in the middle of the flip assembly 4, and then welding will be carried out.

[0042] When the operator wants to adjust the angle of the workpiece to be welded, he only needs to start the electric telescopic rod 22. When the electric telescopic rod 22 is started, it will drive the rack 1 23 to cooperate with the bottom component of the flip component 4, so that the component to be welded can be rotated 180 degrees.

[0043] Furthermore, the bidirectional motor 291 mentioned above is a conventional technical means in the prior art. In this solution, only its transmission function is utilized, and its working principle and circuit connection are not further elaborated here.

[0044] By setting a bidirectional motor 291 to cooperate with the connecting rod 292, the transmission wheel 293 drives the transmission belt 294 and the transmission rope 295 to rotate, thereby achieving the clamping and transportation of the welding workpiece; by setting an electric telescopic rod 22 to cooperate with the rack 23, the precise adjustment of the welding workpiece angle is achieved, which facilitates flexible adjustment during the welding process and improves work efficiency and operation accuracy.

[0046] During the implementation of this embodiment, after the internal components of the flip assembly 4 transport the welding workpiece to the bottom of the pretreatment assembly 5, the transmission motor 52 fixedly connected to one side of the fixed rod 51 will be started, and then the rotating rod 1 53 will be driven to rotate. When the rotating rod 1 53 rotates, the grinding wheel 55 fixedly connected to its outer surface will also move accordingly. Subsequently, while the bidirectional motor 291 rotates, since the outer surface of the output end on the other side is wrapped with a power belt 566, the rotating rod 2 564 will also rotate accordingly when the bidirectional motor 291 rotates. When the rotating rod 2 564 rotates, the four fan blades 565 fixedly connected to its outer surface will supply air while the rotating rod 2 564 is rotating. Further air will pass through the air supply pipe 561 and then be discharged from a number of nozzles 562 to wash the surface of the welding workpiece.

[0047] Furthermore, the connection between the housing 563 and the second rotating rod 564 is sealed, so that when air is supplied, it is only necessary to ensure that there is no air leakage.

[0048] During the implementation of this embodiment, after the internal components of the flip assembly 4 transport the welding workpiece to the bottom of the pretreatment assembly 5, the transmission motor 52 fixedly connected to one side of the fixed rod 51 will be started, and then the rotating rod 1 53 will be driven to rotate.

When the rotating rod 2 564 rotates, the four fan blades 565 fixedly connected to its outer surface will supply air while the rotating rod 2 564 is rotating. Further air will pass through the air supply pipe 561 and then be discharged from a number of nozzles 562 to wash the surface of the welding workpiece.

[0049] Furthermore, the connection between the housing 563 and the second rotating rod 564 is sealed, so that when air is supplied, it is only necessary to ensure that there is no air leakage.

[0050] By setting the transmission motor 52 in cooperation with the rotating rod 1 53, the grinding wheel 55 can grind the surface of the welding workpiece; by setting the bidirectional motor 291 in cooperation with the rotating rod 2 564, the rotating air supply function of the fan blade 565 is realized, and the air is sent to the surface of the welding workpiece through the air supply pipe 561 and the nozzle 562 for blowing, thereby effectively cleaning the surface of the welding workpiece and improving the quality of the welding workpiece; at the same time, the sealing design of the outer shell 563 and the rotating rod 2 564 ensures the sealing during the air supply process, avoids air leakage, and improves the overall efficiency of the system.
