[0002] Since spark plugs are generally cylindrical in structure and need to be placed upright during glazing so that the spray gun can spray the spark plugs, in the prior art, the operation of loading the spark plugs into the glazing area is generally as follows: first, a manual operation is required to place the cylindrical spark plugs in batches into a special material box so that the spark plugs are stacked and stand in the material box, and then a robot is used to grab the cylindrical spark plugs from the material box and put them into a rotating station slot, and then the station slot is rotated to the glazing area for automated glazing operation, such as a patented ceramic spark plug blank. As shown in the glazing device (Announcement No. CN104193413B), this type of production line only realizes continuous automation in the operation when rotating to the glazing area, that is, when the cylindrical spark plugs are initially placed in a disorderly manner, it takes a long time to manually pick and arrange them, and then manually or mechanically rotate the horizontally lying spark plugs to a standing position and align them to the standing slots. This is not only time-consuming and labor-intensive, but also has low alignment efficiency. In addition, it is very easy to cause misalignment due to vibration or accuracy during alignment, resulting in poor accuracy. Summary of the Invention
