Figure 4 As shown, when the material stripper plate 23 rotates a specified angle under the drive of the first motor 21, its short side avoids and its long side limits the workpiece body 5 located in the second position. The workpiece body 5 located in the first position has no obstruction in front and moves forward under the drive of the conveyor belt assembly 1 until it is intercepted by the limit rod 6, thereby achieving preliminary positioning of the workpiece body 5.

[0028] The stripping plate 23 is driven by the first motor 21 to rotate and reset, and the posture of each workpiece body 5 is restored to the following state: Figure 1 and Figure 2 The status shown is preparing for the next material selection.

The workpiece body 5 is placed just at the designated position of the welding table 4, realizing precise loading.

[0031] Among them, the output shaft of the first motor 21 is fixedly connected to the first drive shaft 22 through a coupling, and the first drive shaft 22 is fixedly connected to the material stripping plate 23. When the first motor 21 is working, it can drive the first drive shaft 22 to rotate, and drive the material stripping plate 23 to rotate synchronously through the first drive shaft 22.

When the material-diverting plate 23 is driven by the first motor 21 to rotate to a specified angle, its short side avoids and its long side limits the workpiece body 5 located in the second position. The workpiece body 5 located in the first position has no obstruction in front and moves forward under the drive of the conveyor belt assembly 1 until it is intercepted by the limiting rod 6, thereby achieving the preliminary positioning of the workpiece body 5. The material-diverting plate 23 is driven by the first motor 21 to rotate and reset, and the posture of each workpiece body 5 is restored to the following state.
