The plurality of single-piece suction devices arranged on the variable-spacing module can adjust the spacing according to the interval of the products, and the horizontal movement drives the plurality of single-piece suction devices to move between the tray and the vision detection mechanism after sucking the products. The suction nozzle after sucking the product can move up and down and rotate, and the vision detection mechanism performs vision detection on the four sides of the product.

[0006] It is further characterized in that: the product suction nozzle is arranged on a suction nozzle rod, and the suction nozzle rod is driven to lift by a lifting cylinder; a spiral suction rod movement limiting groove is formed on the rod body of the suction nozzle rod, and a pin shaft is fixedly arranged on one side of the suction nozzle rod, and the pin shaft is arranged in the suction rod movement limiting groove. While the lifting cylinder drives the suction nozzle rod to move up and down, the pin shaft and the suction rod movement limiting groove cooperate with each other, so that the suction nozzle rod rotates synchronously, thereby realizing vision detection on the four sides of the product sucked by the suction nozzle. One set of driving mechanism realizes the lifting and rotation of the suction nozzle rod, reduces the manufacturing cost of the device, has a compact structure, small installation space, and prevents interference between the suction nozzles.

[0007] Further: The pin shaft is fixed on the suction rod holder, and the suction nozzle rod sleeve is inserted into the suction rod holder. The suction rod holder positions and guides the suction nozzle rod, making its lifting and rotation more stable.
