Double-face automatic laminating machine for bent glass and laminating technology thereof

Abstract

The invention discloses a double-face automatic laminating machine for bent glass and a laminating technology thereof. The double-face automatic laminating machine comprises film laminating platforms,a linking carrying mechanical arm, a transfer platform and film taking and laminating mechanisms, the film laminating platforms comprise the first film laminating platform and the second film laminating platform, and the transfer platform is arranged between the first film laminating platform and the second film laminating platform; the two film taking and laminating mechanisms are arranged on the rear side of the first film laminating platform and the rear side of the second film laminating platform respectively; the linking carrying mechanical arm is arranged on the front sides of the filmlaminating platforms and the front side of the transfer platform in the left-and-right direction, and is provided with three sucking assemblies. Through the double-face automatic laminating machine, linking feeding and discharging are realized, films are independently laminated on the two side faces of the bent glass, and therefore the efficiency of film laminating is improved greatly; by pullingout a material belt, individual films are stripped onto a stripping plate, laminating mounting heads are used for forming laminating height difference on the two sides of the films, laminating actionsare completed through line contact, laminating air bubbles are effectively reduced, and the yield of laminating is increased.

Description

technical field [0001] The invention relates to the field of automatic screen manufacturing, in particular to a double-sided automatic bonding machine for curved glass. Background technique [0002] The display screen is an important component of electronic products such as smartphones and tablet computers. In the structure of the display screen, the glass panel is the main structure; in recent years, with the upgrading of electronic products such as mobile phones, 2.5D, 3D and other screens have appeared. Compared with the traditional single-plane structure screen, these screens have upward bending or extending parts at the periphery or sides; in the manufacturing process of this kind of screen, it is necessary to heat-bend the traditional flat glass, and after the bent glass is obtained, it is then processed. Film application: In the actual film application process of curved glass panels, there is a need to apply film to both sides of the curved glass at the same time, in ...

Problems solved by technology

The traditional film lamination machine cannot meet the technical requirements of film lamination on both sides of the curved glass plate. It can only be filmed on one side in a single film lamination machine, then the curved glass plate is taken out and manually turned over, and then put back into the film lamination machine or another A film laminating machine is used to apply film to the other side of the curved glass plate; this film lamination method is cumbersome to operate, and the film laminating efficiency is low, which cannot meet the production capacity requirements of the automated production line; therefore, research and design are required for the double-sided film laminating process of curved glass A new double-sided film sticking equipment to effectively improve film sticking efficiency

In addition, the film-adhesive diaphragm is a single-piece structure. The traditional diaphragm feeding includes tray feeding and material box feeding. Tray feeding generally places multiple diaphragms in each trough of the tray, and through the feeding The manipulator takes out the diaphragm from the trough. The number of diaphragms that can be loaded on the tray of this feeding method is limited, and multiple trays need to be configured to achieve large-scale feeding, and the cost of feeding is high; When feeding, place multiple diaphragms stacked up and down in the material box, and the diaphragms are continuously lifted upwards through the lifting plate at the bottom of the material box, so that the retrieving manipulator can take out the diaphragms from the top of the material box. Large-scale feeding can be achieved by using a single material box, but in the actual feeding process, there is cohesive force between the upper and lower diaphragms when they are stacked, and it is easy to pick up materials when the retrieving manipulator At the same time, take out multiple pieces of film that are bonded together. Therefore, it is necessary to perform multiple inspections before lamination. The operation is cumbersome and inconvenient, and the feeding process is many and the cost is high.

In addition, when the diaphragm and the curved glass are bonded to each other, bonding air bubbles are easily generated between the two bonding surfaces, and the bonding air bubbles affect the bonding quality, resulting in a decrease in the bonding yield
