Screw feeding device of screw driving robot

Abstract

The invention provides a screw feeding device of a screw driving robot. The screw feeding device comprises a support, an X-axis air cylinder is arranged on the support and is in transmission connection with a movable block, and an air nozzle sleeve is mounted on the movable block. An adsorption nozzle is arranged at the bottom of the air nozzle sleeve, and an air hole is formed in the top of the air nozzle sleeve and communicates with the adsorption nozzle. An air blowing nozzle is further arranged in the support and connected with an air blowing pipeline, and the air hole is connected with avacuum valve through an air pipe. When screws are adsorbed, the adsorption nozzle moves to a screw pre-placed position, and the vacuum valve is opened to provide negative-pressure gas to the air hole;and when the screws are fed in a blown mode, the adsorption nozzle moves to the position over the air blowing nozzle, and the vacuum valve is opened to provide positive-pressure for the air hole. Through the screw feeding device, the screw supplying cost of the screw driving robot is greatly reduced, the structure is simple, maintaining is convenient, and the work efficiency is high.

Description

technical field [0001] The invention relates to the technical field of automatic screw locking, in particular to a screw feeding device of a screw locking robot. Background technique [0002] At present, although there are many types of screw locking equipment on the market and are widely used, the screw feeding method is still a major difficulty for automatic screw locking robots. At this stage, the main feeding methods of automatic screw locking robots used in 3C electronics, toys, LED, drones, smart meters and other industries are magnetic suction type (permanent magnetic ring and electromagnetic adsorption), blanking type, and adsorption type. Among them, the air blowing automatic screw locking robot is very popular among customers because of its high efficiency. However, due to the unstable performance of the air blowing feeding method of the current air blowing automatic screw locking robot on the market, such as feeding card material, screw olecranon card At the same...
