[0002] Screws are commonly used fasteners, mainly used to connect two or more parts of a product. At present, the screw assembly of many products is mostly done by workers holding screwdrivers to tighten the screws. However, in the mass production process, the workers often have high labor intensity, low efficiency, high labor costs, and it is difficult to ensure quality consistency, which is far from meeting industrial needs.

[0003] With the transformation and upgrading of my country's manufacturing industry, the production and manufacturing process urgently needs a large number of suitable assembly robots to improve production efficiency and quality and reduce production costs. Therefore, screw locking equipment has emerged to realize automatic screw locking and improve production efficiency. The existing suction-type screw locking equipment needs to be repeatedly moved to the top of the screw loader to adsorb the screws, and then return to the processing position to lock. Due to the limited suction force of the suction equipment, the screws are prone to swing during transportation, resulting in the phenomenon of slipping caused by changes in the movement angle of the rail and the interlacing of the rail.
