Full-automatic film detecting and pasting production line and film pasting process thereof

Abstract

The invention discloses a full-automatic film detecting and pasting production line and a film pasting process thereof. The production line comprises a film feeding assembly, a film taking and detecting mechanical arm, a film transfer table, a correcting and mounting mechanical arm, a film tearing assembly, a glass loading assembly and a turntable; the film pasting process comprises the followingprocess steps of transferring a material frame, picking up the glass sheets and laminating the empty material frames, removing dust of the glass and photographing, film feeding, double-piece detectingand correcting, film recovering and primary correction, film taking and film tearing, membrane position correcting and film pasting. According to the film detecting and pasting production line and afilm pasting process, automatic centralized feeding of the diaphragm and the glass sheet is realized, the production line has a film suction quantity detection function and an automatic film tearing function on the surface of the film, the situation of sticking the double films is effectively avoided, the accuracy of the position of the film pieces in the film tearing process is guaranteed, the bending situation of the film sheet during film tearing is reduced, a sticking head which integrates the functions of film collecting sheet correction and pasting and mounting is adopted, in the film pasting process, the film is in contact rolling with the edge of the glass sheet, so that the situation of film sticking bubbles and crease marks can be effectively reduced, and the film sticking quality can be improved.

Description

technical field [0001] The invention relates to the field of mechanical automation, in particular to a fully automatic film detection and film-attaching production line and its film-attaching process. Background technique [0002] The display screen is an indispensable part of electronic products such as smartphones and tablet computers. The display screen can not only intuitively display information such as video patterns, but also allow users to input various commands through the display screen to complete different functions; the display screen is mostly composed of Glass is used as the substrate, and various films are attached to the glass sheet to protect the glass and produce different optical effects. Therefore, the film sticking process is an indispensable processing process in the display manufacturing process. With the continuous improvement of production capacity and cost control requirements, film sticking automation and the use of machines to complete the screen...

AI Technical Summary

Problems solved by technology

Since the diaphragm is mostly a sheet-like structure with a certain area, when the diaphragm is attached to the glass sheet, air bubbles, creases, etc. are easily generated between the diaphragm and the glass sheet, and the quality of the film is difficult to guarantee; specifically, in the film automation There are the following key technical difficulties to be solved: 1. Centralized and automatic feeding of diaphragms and glass sheets to reduce the frequency of refueling and improve feeding efficiency; 2. The feeding of diaphragms is generally fixed by vacuum adsorption, but the suction nozzle There are two or more pieces of the adsorbed diaphragm, which leads to the problem that the subsequent tearing of the film cannot be completed; 3. The problem of automatic tearing of the film on the surface of the diaphragm and the movement of the diaphragm position and the bending of the diaphragm during the tearing process; 4. . Diaphragm correction and placement integration to reduce equipment structure and reduce production costs; 5. Film defects such as bubbles and creases in the process of diaphragm film attachment
