Automatic automobile body-in-white welding spot division method based on sphere interference

The invention relates to an automatic automobile body-in-white welding spot division method based on sphere interference. The method includes the following steps that firstly, a board tree structure is established according to a welding sequence; secondly, level marking is conducted on joints of a board structure tree; thirdly, a welding spot sphere is established with each welding spot as the center; fourthly, interference calculation is conducted on the welding spot balls and boards, and an interference board set is acquired; fifthly, according to the interference number and the welding layer number, welding spots are divided according to a certain division principle, and the welding spots are divided into the corresponding board assembly joints.
