Abstract

The invention relates to a detection system and a pole piece measuring method, the detection system comprises a base, a first conveying piece, a supporting assembly, a generator and a detector, and the first conveying piece is used for conveying pole pieces in a first direction. The supporting assembly is connected with the generator and the detector and used for driving the generator and the detector to get close to or away from the pole piece in the second direction, the generator is provided with a projection opening, the size of the projection opening in the first direction is larger than that in the second direction, and the first direction, the second direction and the third direction intersect pairwise. The pole piece measuring system has a measuring state, in the measuring state, the supporting assembly drives the generator and the detector to reciprocate relative to the pole piece in the second direction, the generator and the detector are located on the two opposite sides of the pole piece in the third direction, and the generator emits rays through the projection opening. The detector detects the rays emitted by the generator and obtains a radiation intensity measurement value. Therefore, online measurement of the pole piece is realized, and the measurement precision is improved.
