Abstract

The invention relates to a dispensing method comprising the following steps of: keeping pressure of a hot melt adhesive gun unchanged and improving the dispensing speed for a plurality of times; forming a connected and continuous adhesive wire by use of a hot melt adhesive on the bracket; then connecting a touch screen lens in a sealed manner; lessening the width of dripping the hot melt adhesive on the bracket, and forming the connected and continuous adhesive wire by use of the hot melt adhesive, namely forming the very thin adhesive wire when the adhesive wire is viewed from the surface of the bracket; and then connecting the touch screen lens, so that the four sides of a front-arranged camera hole are entirely sealed. The defects in the prior art of large distance ratio between the camera hole and a front shell, discordant whole body, and inaesthetic appearance can be overcome. The dispensing method provided by the invention is applicable to a design that the distance between the front-arranged camera hole and a headphone and the distance between the front-arranged camera hole and the front shell are less than the adhesive path width on the plane of the bracket.

Description

technical field [0001] The invention belongs to a glue dispensing method, in particular to a glue dispensing method and a portable mobile terminal, and belongs to the field of mechanical technology. Background technique [0002] At present, along with the popularization and use of portable mobile terminals supporting 3G functions, in order to realize the video call function in the 3G functions, it is necessary to install a camera on the front of the mobile communication terminal, i.e. a front camera, so that the camera can be aimed at the operator. [0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art. Since the bracket and the lens are bonded together by hot-melt adhesive, the surroundings of the camera hole on the bracket need to be sealed with hot-melt adhesive. Make it impossible for dust to enter the area of ​​the front camera hole from between the lens and the bracket; since the d...
