Abstract

The invention relates to a pressing stick which comprises a tube body and a cover body assembled at one end of the tube body, wherein the upper part of the cover body is communicated with an air inlet pipe, the tube body is provided with a glue injection end and a pressing end opposite to the glue injection end, and the glue injection end is connected with the cover body. The glue injection end is provided with a glue storage chamber, the bottom of the glue storage chamber is provided with a plurality of glue outlets, and the end surface of the pressing end is provided with a ring dispensing hole communicated with the glue outlets of the glue storage chamber. The pressing stick integrates the functions of the traditional pressing stick and a dispensing device, can complete the pressing and dispensing of an optical assembly together during t assembling the lens, and also can improve the assembly efficiency.

Description

technical field [0001] The invention relates to a pressing rod, in particular to a pressing rod used for lens assembly. Background technique [0002] When assembling the existing lens modules, it is often necessary to assemble and glue multiple lenses, spacers, light shields, etc. together to form a lens group, and then assemble the multiple lenses in the lens barrel to form a lens module. [0003] The assembly of the existing lens group is to ensure the accuracy of the assembly and avoid the eccentricity between the assembled lenses, the lens and the spacer, the light blocking film and other optical components. Optical components such as chips are assembled in an assembly tray. [0004] During assembly, press rods are used to sequentially press optical components such as lenses, spacers, and light blocking sheets into the assembly holes in the assembly tray. Before or during the pressing, every two adjacent optical components Components need to be fixed by dispensing. ...
