QGIS raster generation with defined grid [closed]

Is there a way in QGIS to define a grid and generate separate tiff files for every grid cell? Like in this matter:

• Open XYZ Tiles -> OpenStreetMap.
• Use a tool to define a grid over the interesting area.
• Generate a separate tiff file for every sell, using a selected Projection and Scale

Visualization of the idea:

• Is there a existing QGIS tool for this?
• Is there a existing QGIS plugin for this?
• Do I have to create a custom script or plug-in for this task?
• Is there a existing tool to "split"/"warp" a big tiff to amount of X and Y columns and rows to create smaller tiff files. (Problem is when creating big maps, for example whole Sweden)
