The receiving assembly can limit the position of the cover f1 on the carrier 413 and prevent the cover f1 from moving or falling off during the conveying process. Specifically, prior to placing lid f1 on the receiving assembly, the gripping blocks are moved outwardly by the seventh drive assembly to facilitate placement of lid f1 on the receiving assembly. After the cover f1 is placed on the receiving assembly, the clamping blocks move inward under the action of the seventh driving assembly, and abut against the side edge of the cover f1 to fix the cover on the carrier 413.

The pickup unit 425 places the seal ring picked up from the seal ring stage on the second rotation stage 4231, and the camera and the light source perform appearance inspection of the seal ring while the seal ring is performing rotational movement on the second rotation stage 4231 to determine whether the seal ring is a good product. In addition, after one side of the sealing ring is detected, the first clamping and overturning assembly 4233 is used for clamping and overturning the sealing ring, so that the camera and the light source can detect the other side of the sealing ring, the omnibearing detection of the sealing ring is realized, the detection precision of the sealing ring is improved, and the assembling quality of the assembling device is further improved.

In one embodiment, after the first detecting assembly 423 detects the sealing ring, the picking assembly 425 picks up and transfers the sealing ring to the oil spraying assembly for oil spraying operation, and the oil sprayed sealing ring is mounted on the motor vehicle component for lubrication, so that friction between parts of the water tank is reduced, and the service life of the motor vehicle component is further prolonged.

Specifically, pick up subassembly 425 and place the sealing washer on the first rotatory microscope carrier of oil spout subassembly, the sealing washer carries out rotary motion under the effect of first rotatory microscope carrier, and the oil spray gun spouts the oil to the sealing washer in the rotation process simultaneously to improve the homogeneity of sealing washer spraying.
