[0002] As we all know, the touch screen of a mobile phone generally needs to be fixed on the face shell. The positioning device for the touch screen face shell of a mobile phone is an accessory device used for positioning and fixing the touch screen and the face shell of a mobile phone, so as to better produce the touch screen of a mobile phone. It has been widely used in the field of the electronics industry; the existing positioning device for the touch screen cover of the mobile phone includes an operating table, a left front outrigger, a left rear outrigger, a right front outrigger, a right rear outrigger, a front beam and a rear beam , the tops of the left front outrigger, left rear outrigger, right front outrigger and right rear outrigger are respectively connected with the left front side, left rear side, right front side and right rear side of the bottom of the console, and the front beam is located at the left front outrigger and right rear side between the outriggers, and the left end of the front beam is connected with the middle part of the right end of the left front outrigger, and the right end of the front beam is connected with the left end of the right front outrigger; Place it on the panel, then take the cover manually, align it with the touch screen of the mobile phone, and fit and fix it; the existing positioning device for the cover of the touch screen of the mobile phone is found in use, manual positioning and fit, the positioning is not accurate, the product The quality is poor, the production efficiency is low, and the use limitations are high; and due to manual operation during the lamination process, a lot of dust and impurities are adsorbed between the surface shell and the touch screen of the mobile phone, polluting the surface shell, and the bonding yield is low, resulting in its low reliability
