US Patent 12018936 Mounting apparatus and parallelism detection method in mounting apparatus

The present invention provides a mounting apparatus and a parallelism detection method in the mounting apparatus. The parallelism detection method in the mounting apparatus includes: a first height detection process of detecting first heights of a mounting tool when a holding surface comes into contact with the a tip of a triangular pin by placing the triangular pin on a placement surface of a stage and lowering the mounting tool; a second height detection process of detecting second heights of the mounting tool when the tip of the triangular pin comes into contact with the placement surface by holding the triangular pin on the holding surface of the mounting tool and lowering the mounting tool; and a parallelism calculation process of calculating the parallelism between the placement surface of the stage and the holding surface of the mounting tool based on the first heights and the second heights.
