Background A workshop produces a batch of poles as shown in fig. 1-3 for assembly to an electronic product. The pole comprises a square plate 1 and a circular column platform 2 fixedly arranged on the top surface of the square plate 1, four bevel ports 3 are formed in the cylindrical surface of the circular column platform 2 around the circumferential direction of the circular column platform, the two bevel ports 3 positioned on the left side form a V shape, and the two bevel ports positioned on the right side form a V shape. For reasons of processing technology, only 1 or 2 bevel openings 3 are processed on some number of polar posts, but in fact, 4 bevel openings 3 are required to be processed on the polar posts, so that workers are required to detect processing defects of each polar post. The method for detecting the processing defects of the pole in the workshop comprises the following steps: S1, taking out a pole to be detected from a charging basket by a worker, holding a square plate 1 of the pole by hand, then rotating the square plate 1, and driving a circular column platform 2 to synchronously rotate by the square plate 1, wherein in the rotating process, the worker observes the circular column platform 2 of the pole; If the four bevel ports 3 are observed on the pole, the detected pole is not provided with the machining defect, and the worker judges the pole as a qualified product, thereby finishing the detection of the machining defect of one pole; S2, the worker repeats the operation of the step S1 for a plurality of times, and therefore machining defects of a batch of polar posts can be detected. However, the detection method in the workshop can detect the processing defects of a batch of polar posts, but the following technical defects still exist in the technology: The worker can only detect the machining defects of the poles one by one, and the detection of up to 600 poles is required in one day, so that a long time is required to finish the detection of all 600 poles, which certainly reduces the detection efficiency of the machining defects of the poles.
