[0002] With the development of domestic automobile industry, the demand for various shock absorbers, pneumatic elements and brakes is also increasing, among which the connecting rod is the core element of these devices. After processing, welding and chrome plating, these elements not only require high dimensional accuracy, but also require smooth and defect-free surface. However, due to the influence of electroplating and transportation, surface scratches, scuffs and pinholes may occur on the connecting rod. Therefore, before the connecting rod is put into use, visual inspection equipment is needed to detect the shape accuracy and surface roughness of the connecting rod.

[0003] Since the surface of the connecting rod is often attached with oil stains, in order not to affect the detection accuracy, the surface of the connecting rod needs to be manually wiped and cleaned before detection. However, manual wiping still has some omissions, and the efficiency is not high, and the electroplated surface is easy to be damaged. Therefore, there is a high probability of producing defective products. In addition, due to clamping, equipment vibration and other reasons during the detection process of the connecting rod, the visual inspection equipment cannot accurately identify the degree of contour change of the connecting rod, which reduces the working efficiency of the detection equipment.

After the connecting rod passes through the three unfolded fascia, the elastic potential energy of the fascia is released, and the scraped oil stains are bounced onto the center rail. The oil stains flow into the oil tank through the inclined straight groove at the bottom of the center rail, thus cleaning the oil stains on the connecting rod.

[0015] 2. By creating V-grooves on the centering rail, the cylindrical contour of the object is aligned and positioned.

The laser of the laser emitter becomes unstable with the rotation of the connecting rod, and the degree of change is more easily received and identified by the receiving camera. The control system makes the sprayer work and marks the connecting rod with shape error for easy manual identification. Attached Figure Description
