Description

Technical Field

[0001] The present invention relates to the technical field of welding machines, in particular to a material taking manipulator and a material taking method for a motor stator welding machine. Background Art

[0002] The motor stator is made of multiple stator sheets of the same size and shape stacked and spliced together. After welding, most existing motor stator welding machines use manual labor to transfer the welded stator from the welding machine to the assembly line for the next step of processing. This method has the following disadvantages: 1. The temperature of the stator after welding is high, and the user often needs to wait until the stator temperature is lower before transferring the stator to the assembly line, wasting a lot of time and reducing work efficiency; 2. During the transfer process of the stator after welding, there is no good fixing equipment, which can easily cause the stator to fall and cause wear; 3. Long-term manual removal of the stator increases labor, which is not conducive to long-term work of workers. To this end, we propose a material-retrieving robot and a material-retrieving method for a motor stator welding machine. Summary of the Invention
