[0002] OCA full bonding is a device used for assembling screens of electronic products such as mobile phones and tablets. OCA (Optically Clear Adhesive) is a transparent adhesive used to bond touch screens to glass panels.

[0003] For example, the patent with the national authorized patent announcement number CN210617292U discloses a bonding mechanism for OCA optical glue, in which the OCA optical glue conveying mechanism is installed on the machine and includes a rotatable bonding wheel, and the carrier tape bonded with the OCA optical glue passes around or rests on the bonding wheel to convey the OCA optical glue; the protective film conveying mechanism is installed on the machine and includes a rotatable roller, and the protective film bonded with the circuit layer passes around the roller to convey the protective film; when the OCA optical glue is conveyed between the bonding wheel and the roller, the top surface of the OCA optical glue is bonded to the protective film and moves synchronously with the protective film to complete the bonding action.

[0017] 1. Through the design of the linear module, the moving block, the rack, the gluing mechanism, the pressure-applying material mechanism and the storage cylinder, when in use, the staff can place the touch screen in the embedded groove of the moving block, and then start the linear module to make the moving block drive the touch screen to move into the gluing mechanism, and the moving block entering the gluing mechanism will be meshed with the gluing mechanism through the rack, so that the OCA transparent adhesive in the gluing mechanism can be evenly laid on the surface of the touch screen in a horizontal manner, until the moving block drives the touch screen to move out of the gluing mechanism, and the gluing mechanism will automatically close after it is not meshed with the rack to prevent the outflow of the OCA transparent adhesive, and then the moving block will drive the glued touch screen to the set position and stop, and at the same time, the pressure-applying material mechanism will rotate to be flush with the storage cylinder, so that the pressure-applying material mechanism can absorb and take out the stacked glass panels in the storage cylinder, and then rotate back to its original position, so that the absorbed glass panels can be aligned with the embedded groove of the moving block. The touch screens placed inside are flush with each other, and then the pressure-taking mechanism will drive the glass panel to apply pressure on the touch screen, and the pressure of the pressure-taking mechanism can spread the glue applied laterally on the upper surface of the touch screen to all sides and evenly fill the entire touch screen and the glass panel. Then, after the pressure time reaches the set value, the pressure-taking mechanism will lift the glass panel, and the touch screen will lift the touch screen together through the OCA transparent adhesive. Then, the pressure-taking mechanism will transfer the bonded touch screen and glass panel to the corresponding position, and then remove the suction to place it in the required position for stacking. The whole process can be achieved by only placing the touch screen into the moving block, so that it has the effect of sucking and taking out the glass panel for automatic loading and unloading after the bonding is completed, which will reduce the workload and labor cost of the staff, improve production efficiency, and increase the degree of automation and controllability of the production process.

[0018] 2. Through the design of the U-shaped frame, storage box, discharge port, gear, connecting column and transfer port, after the staff places the touch screen in the embedded groove of the moving block, they can start the linear module to make the moving block drive the touch screen to move into the U-shaped frame. The moving block entering the U-shaped frame will mesh with the gear in the U-shaped frame through the rack, and with the continuous movement of the moving block, the meshing gear can drive the connecting column to rotate together. When the transfer port opened on the outer surface of the connecting column rotates to face the storage box, the OCA transparent adhesive in the storage box can enter the transfer port, and with the rotation of the connecting column, the connecting column can drive the transfer port containing the OCA transparent adhesive to face the touch screen, and then The OCA transparent adhesive in the transfer port can be evenly applied laterally on the surface of the touch screen until the movable block drives the touch screen to move out of the C-shaped frame. After the gear is no longer engaged with the rack, the discharge port in the storage box will be blocked and sealed by the stopped connecting column, thereby preventing the outflow of the OCA transparent adhesive and achieving the effect of automatic gluing. Applying the glue laterally at intervals can avoid the waste caused by the pressure of the glass panel after the glue is applied, thereby ensuring that the glue is evenly distributed on the surface of the touch screen, avoiding local excess or deficiency, thereby ensuring the uniformity of glue use and quality stability.
