[0028] After the line horse linear module 11 moves over, it puts the pole piece 13 on the product inspection platform 3. The product inspection platform 3 generates a vacuum to adsorb the pole piece 13. The suction cup group 8 of the line horse linear module 11 breaks the vacuum, and the Z-axis lifting module 10 returns to the standby position. The line horse linear module 11 moves back to the material picking area. During the movement, the line scanning camera 12 starts to work to detect whether the pole piece 13 is qualified.
