Embodiment 1

[0048] Such as Figure 1-Figure 4 As shown, the automatic online visual detection device for the appearance defect of the motor commutator includes a clamping mobile device, a detection table, a top camera device, a side camera device and a sorting chute. The clamping mobile device includes a plurality of horizontal clips, Horizontal clip opening and closing drive mechanism, slide plate 3 with multiple horizontal clips and a slide plate drive mechanism that drives slide plate 3 to move horizontally. The photographing device is located directly above the top surface inspection platform 13, the side photographing device is located on the front side of the side inspection platform 16, and the horizontal clamp includes horizontally transporting the commutator 2 from the product inlet to the top surface. The first horizontal clamp 6 of the detection platform 13, the second horizontal clamp 7 that horizontally transports the commutator 2 from the top surface detection platform 13 to...

Embodiment 2

[0071] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the top detection table 13 includes a first carrier 130 and a first light source 131 located below the first carrier 130, and the first carrier 130 is transparent plate, the image clarity affects the analysis and judgment of the final good product and defective product, and the image clarity is related to the sharpness of the picture taken. When the first light source 131 shines upward from the bottom of the commutator 2, the collected The part of the picture to be tested is black, the sharpness of the picture is better, and the detection accuracy is higher. However, when the first light source 131 illuminates from top to bottom, the part of the collected picture to be tested is white and the sharpness is poor.

[0072] The specific working process is:

[0073]After the commutator 2 is transported to the position by the feeding conveyor belt 1, it reaches the product arrival por...

Embodiment 3

[0075] Such as Image 6 As shown, the automatic online visual detection method for the appearance defect of the motor commutator adopts the automatic online visual detection device for the appearance defect of the motor commutator in Embodiment 2 to detect, including the following steps:

[0076] Step 1: a plurality of commutators are sequentially fed from the inlet of the feed conveyor belt 1, and the inlet of the feed conveyor belt 1 is connected to an external commutator production output device;

[0077] Step 2: The first commutator moves through the feed conveyor belt 1 to reach the product arrival port, and the first horizontal clamp 6 clamps the first commutator;

[0078] Step 3: The first commutator moves to the top surface detection platform 13 and performs top surface detection, and at the same time, the second commutator moves to the product arrival port;

[0079] Step 4: The first commutator is translated to the side inspection table 16 for side inspection, while ...

The device has the advantages of high detection speed and detection precision and the like.

Description

technical field [0001] The invention relates to the technical field of online visual detection, in particular to an automatic online visual detection device and detection method for appearance defects of a motor commutator. Background technique [0002] In the manufacture of DC motors and AC series motors, the commutator is a key component, and its quality level directly affects the overall quality of the motor. The appearance quality problems of the commutator due to its own material defects, processing defects or improper logistics delivery, such as bruises and other appearance defects, must be rejected as defective products. The existing quality control mode is manual visual inspection, which is not only inefficient, but may also cause missed inspections due to visual fatigue. [0003] For this reason, an online visual inspection device has appeared to replace artificial vision. Visual inspection is to use machines instead of human eyes for measurement and judgment. Vis...
