After the action of rotating for one circle is finished, the product waits for the triggering action fed back from the station a and runs from the station b to the station c.

3. When the product is at the station c, the motor 36 directly drives the jacket 32 to rotate for a circle, the first linear array camera unit 10 and the second linear array camera unit 13 work simultaneously, and the condition of the welding seam of the welding spot is judged. After the action of rotating for one circle is finished, the product waits for the triggering action fed back from the station a and runs from the station c to the station d.

4. And the station d is a material waiting/discharging position, and a manipulator can be additionally arranged on the left side of the station d for automatic discharging under the condition of need. And the product waits for the triggering action fed back from the station a and runs from the station d to the station a.

5. The staff judges the qualification condition of product through the colour of warning light 8.

6. And repeating the steps to detect the next product.
