[0025] Base 1;

[0026] Automatic flipping mechanism 2 is set on top of base 1 and is used to automatically discharge the welded workpieces.

[0027] The workpiece positioning mechanism 3 is mounted on the automatic flipping mechanism 2 and is used to position the workpiece to be welded.

[0028] The workpiece positioning mechanism 3 includes a first positioning plate 31, a second positioning plate 33, a first workpiece 35, and a second workpiece 36. The top of the first positioning plate 31 has a first fitting groove 32, and the top of the second positioning plate 33 has a second fitting groove 34. The second positioning plate 33 is movably abutted against the top of the first positioning plate 31. The first workpiece 35 is movably inserted into the inner cavity of the first fitting groove 32, and the second workpiece 36 is movably inserted into the inner cavity of the second fitting groove 34. Both the first positioning plate 31 and the second positioning plate 33 have connecting grooves 37. In the initial state, the first positioning plate 31 and the second positioning plate 33 are connected as a whole. The first workpiece 35 and the second workpiece 36 are inserted one by one into the inner cavity of the first fitting groove 32 and the second fitting groove 34, which realizes the positioning function of the first workpiece 35 and the second workpiece 36, which facilitates the welding work. After welding, the first positioning plate 31 and the second positioning plate 33 are flipped over as a whole, and the assembled workpieces inside after welding can be placed.

[0029] As one implementation method in this embodiment, such as Figure 2As shown, a bolt 38 is movably inserted into the inner cavity of the connecting groove 37, and a nut 39 is threadedly connected to the end of the bolt 38. During the installation process, the first positioning plate 31 and the second positioning plate 33 are stacked, and then the bolt 38 is inserted into the inside of the connecting groove 37. Then the nut 39 is rotated and installed on the end of the bolt 38, thus completing the assembly of the first positioning plate 31 and the second positioning plate 33.

[0030] As one implementation method in this embodiment, such as Figure 4 As shown, a mounting hole 11 is provided at the corner of the top of the base 1, and a sloping groove 12 is provided on the top of the base 1 near the right side. A rubber plate 13 is fixedly connected to the inner wall of the sloping groove 12. The base 1 can be installed and positioned as a whole through the mounting hole 11 with the help of screws. Through the design of the rubber plate 13, the combined workpieces placed in the workpiece positioning mechanism 3 can be protected against fall.

[0031] As one implementation method in this embodiment, such as Figure 3 As shown, the automatic flipping mechanism 2 includes a sleeve 21, which is fixedly installed on the top of the base 1. A stand 22 is fixedly installed on the inner wall of the sleeve 21. Through the design of the sleeve 21, the stand 22 can be reinforced and supported.

[0032] As one implementation method in this embodiment, such as Figure 3 As shown, a stepper motor 23 is fixedly installed on one side of the stand 22, and a rotating shaft 25 is rotatably connected to the other side of the stand 22. The output shaft of the stepper motor 23 is fixedly connected to the end of the rotating shaft 25. A motor controller 24 is fixedly installed on the outer wall of the stand 22. After the workpiece embedded inside the workpiece positioning mechanism 3 is welded, the stepper motor 23 is controlled by the motor controller 24 to drive the rotating shaft 25 to rotate 180 degrees, which can tilt out the assembled workpiece inside the workpiece positioning mechanism 3. Then, the stepper motor 23 is controlled to drive the rotating shaft 25 to rotate and reset. It is worth noting that the stepper motor 23 and the motor controller 24 in this solution are described by those skilled in the art. The equipment available on the market has not undergone structural modifications as described in this paper. Therefore, those skilled in the art are familiar with its working principles based on their professional knowledge and can apply it proficiently. Thus, this paper will not elaborate on it further. Furthermore, this solution aims to protect the physical structure, but does not provide protection for the circuit and software control. The proposed processing circuit is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not seek protection for the algorithm and circuit technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

Through the cooperation of the kit 26 and the bracket 27, the workpiece positioning mechanism 3 can be supported as a whole on the rotating shaft 25.

[0034] As one implementation method in this embodiment, such as Figure 3 As shown, the side of the card holder 27 is threaded with a clamping bolt 28. The first positioning plate 31 is movably inserted into the inner cavity of the card holder 27. The threaded end of the clamping bolt 28 is movably abutted against the outer wall of the first positioning plate 31. During installation, the first positioning plate 31 is inserted into the inside of the card holder 27, and then the clamping bolt 28 is tightened, so that the threaded end of the clamping bolt 28 abuts against the outer wall of the first positioning plate 31, thus completing the installation of the first positioning plate 31.

[0035] Working principle: During installation, place the first positioning plate 31 and the second positioning plate 33 overlappingly, then insert the bolt 38 into the connecting groove 37, and then rotate the nut 39 to install it on the end of the bolt 38, thus completing the assembly of the first positioning plate 31 and the second positioning plate 33. Insert the first positioning plate 31 into the holder 27, and then tighten the clamping bolt 28, causing the threaded end of the clamping bolt 28 to abut against the outer wall of the first positioning plate 31, thus completing the installation of the first positioning plate 31. In use, place the first working... The first workpiece 35 and the second workpiece 36 are inserted into the first fitting groove 32 and the second fitting groove 34 one by one, which realizes the function of positioning the first workpiece 35 and the second workpiece 36, facilitating the welding work. After the workpiece embedded in the workpiece positioning mechanism 3 is welded, the stepper motor 23 is controlled by the motor controller 24 to drive the rotating shaft 25 to rotate 180 degrees, which can tilt out the combined workpiece inside the workpiece positioning mechanism 3. Then, the stepper motor 23 is controlled to drive the rotating shaft 25 to rotate and reset.
