Technical Field

The present invention relates to an applicator, and more particularly to an applicator for viscous liquids.

Background

At present, in order to solve the problem that a screw looses two objects after the screw is locked, anti-loosening glue is coated on a screw rod of the screw, and after the anti-loosening glue is dried, a solidified coating is formed on the surface of the screw rod, so that the screw is pressed and extruded by the anti-loosening glue to generate reaction force and friction torque force in the locking process, so that the resistance to vibration and the like is improved, therefore, the problem of loosening of the screw is solved, and meanwhile, gaskets and the like can be omitted, so that the assembly efficiency is improved.

The screw glue dispenser is mainly composed of a driving component, a glue dispensing component and a feeding component, wherein a turntable in the driving component rotates at a specific rotating speed, glue is coated on the circumference of the turntable by a glue dispensing gun in the glue dispensing component, a feeding rail in the feeding component transfers a screw to be subjected to glue dispensing towards the turntable, and the feeding component is also matched with a leaning seat which is arranged on one side of the turntable and is in proper gap contact with the turntable so that the screw can enter the gap between the leaning seat and the turntable by the guide of the feeding rail, and the screw is contacted with the turntable by the leaning seat to roll along with the turntable and is adhered with the glue on the circumference of the turntable so as to finish the processing of a screw tooth coating layer of the screw. However, in practical use, the following disadvantages to be improved still exist:

first, the structure required for performing dispensing is too complex. When the screw is used for dispensing, besides the design of the turntable, a leaning seat which is in proper clearance with the turntable and leans against the turntable is additionally arranged on one side of the turntable, so that the screw can enter the clearance between the leaning seat and the turntable through the feeding track to finish the dispensing operation of the screw, and the defect that the structure required by dispensing is too complex is highlighted.

Secondly, the applicability of the dispensing size is not sufficient. The screws have different sizes and different diameters and lengths, so that the dispensing height of the dispensing gun must be changed in cooperation with the screws having different lengths, and thus, the screws must be replaced by other components of different sizes, which results in the disadvantage of time and labor consumption due to different dispensing sizes.

Thirdly, the glue dispensing gun is inconvenient to clean. Because the glue solution used by the glue dispensing gun for dispensing is a viscous liquid, the glue solution can be more or less attached to the outer periphery of the glue injection pipe of the glue dispensing gun in the process of dispensing by the glue dispensing gun, and if the glue solution is not removed within a specific time, the glue injection pipe is solidified by the glue solution, so that the glue injection operation of the glue dispensing gun is hindered; on the other hand, if the photoresist removing operation is performed manually, the defects of time and labor consumption will be caused.
