Description

Technical Field

[0001] The present invention relates to the technical field of display assembly, and in particular to a display assembly device and method. Background Art

[0002] Display assembly devices mainly include automatic alignment laminators, bonding machines (COG / FOG), dispensing machines, curing furnaces, detectors, etc. Precise assembly of various components (such as panels, backlight modules, driving ICs, etc.) is achieved through special operation industrial robots, vision positioning systems, and PLC control. The method is usually: cleaning the substrate → automatic alignment lamination (such as OCA optical glue lamination) → driving chip bonding (hot pressing or ultrasonic process) → sealing and dispensing (UV or thermal curing) → quality inspection (brightness, chromaticity, defects, etc.). The whole process requires a dust-free environment and automated control to ensure the yield rate.

[0003] In the prior art, a Chinese invention patent with the application number 202411911773.5 is specifically a display assembly device, including an assembly table. A placement frame is arranged inside the assembly table for placing the display main body. A first pull rod is movably arranged on the assembly table, and a second pull rod is movably arranged on the assembly table with its end face being spherical. A rotation switching unit is arranged inside the assembly table, which can drive the rotation switching unit to accurately place the outer frame on the back of the display for assembly. A rear cover flipping assembly is arranged on the assembly table to reduce the generation of gaps. In this display assembly device, by setting the first pull rod, the rotation switching unit can be driven to operate, and then the pneumatic component is started. The pneumatic component relies on pneumatic thrust to lead the placement frame to rotate. During this process, the display main body is smoothly flipped to ensure that the required outer frame of the display can be accurately assembled onto the display. This process not only achieves precise installation but also can greatly improve the overall work efficiency.

After the electric push rod B (301) sends the conveyor belt B (306) under the display screen, the electric push rod A (201) resets and places the display screen above the conveyor belt B (306). S6: The controller (400) controls the reversing motor (303) to rotate, respectively conveys display screens of different specifications to different workstations for the next process, and the display screen assembly process is completed.
