Background

The threaded connection has the advantages of simplicity, reliability and convenience in adjustment, and is the most widely applied connection structure in modern structures and mechanical equipment. The general screw connection has self-locking performance, and in product transportation or the moving parts of the product, the joint needs to bear the action of impact, vibration and temperature change, so that the pretightening force is easy to reduce and loosen, thereby causing connection loosening and leading to safety and quality accidents. It is common practice to loosen the screws by pre-gluing. The pre-coating glue is prevented from loosening by solidifying the glue solution on the screw, so that the engineering plastic is extruded to generate a reaction force in the locking process of the thread, and the friction force between the threads of the thread is increased, thereby achieving the effect of preventing loosening. Simultaneously, the fastener is coated with glue to realize the following effects: powerful locking function increases coefficient of friction, and the fastening force is stable, the adjusting screw of unrelaxe, the leak stopping effect, and the lightweight does not rust, and the durability is good.

The existing screw glue dispensing method is rotary disc type glue dispensing, screws are placed on a rotary disc, and then the rotary disc rotates, and meanwhile glue dispensing can be conducted on the screws according to the rotating track of the rotary disc. However, the distance between the turntable of the existing turntable type dispensing machine and the dispensing machine cannot be adjusted, and when some screws with smaller models are dispensed, the distance is too far, so that the dispensing position is not accurate; or when the glue is not available in the glue dispenser, the glue dispensing effect is not good if the distance is too far, and waste is caused if the glue dispenser is replaced with a new one.
