Therefore, many large automotive commutator manufacturers have also realized this problem and have begun to transform and upgrade manual inspections of production lines to automated visual inspection equipment to improve efficiency and ensure quality. Faced with this reality, it is imperative to develop a complete online inspection system for automotive commutator appearance defects.

[0004] However, in actual use, it was found that due to the large number of commutators produced by the manufacturer, dust may adhere to the outside of the commutator. The dust will form a thin film on the surface of the commutator, which may cause the outline of the object to be blurred when the scanner is shooting, affecting the imaging effect of the detector. Utility Model Content

[0015] 2. The appearance inspection device for the commutator can adsorb dust in the internal air through the negative pressure suction holes on the negative pressure suction plate by engaging the working frame with the sealing cover, thereby adsorbing dust in the air inside the working frame, keeping the inspection environment clean, reducing the influence of dust on the commutator, and improving the imaging effect of the detector;

[0016] 3. The appearance inspection device for the commutator can intercept and filter the adsorbed dust by installing a filter in the filter box to reduce the amount of dust inside the working frame.

[0017] The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
