The display is an important component of multimedia equipment, and full-lamination is an important and high-end process technology in display lamination, and the problem of bubble defects is particularly prominent in large-size full-lamination technology.
The existing full-lamination bubble defect maintenance only comprises disassembly and rework, the disassembly and rework technology is mature in the full lamination of small-size OCA (optical clear adhesive) and OCR (optical liquid adhesive), and for large sizes, due to the fact that the area of a product is enlarged, fragments and other appearance and function defects are easy to occur in disassembly, and the yield loss of the disassembly machine is large. In addition, the SCA (an optical transparent adhesive) process can not be disassembled after being fully laminated and cured.
The OCA small-size full-lamination disassembling technology mainly comprises the steps of disassembling in a low-temperature freezing environment, enabling the viscosity of an OCA adhesive material to lose efficacy at the temperature below-60 ℃ through a freezing refrigerator, and then manually separating a full-lamination display panel from a protection panel, wherein the disassembling is easy to break, the display panel falls off, and the functions and the water vapor invasion are poor. The OCR small-size full-lamination disassembling technology mainly comprises molybdenum wire cutting and disassembling, wherein a display panel and a protection panel are separated through molybdenum wires or other filament cutting colloids, and the disassembling is easy to have the conditions of fragments, surface scratches, functional defects and the like. The SCA reworking does not have the technology of disassembling at present, once originally can't disassemble admittedly, no matter be freezing and disassemble or the molybdenum filament cutting can't separate the laminating panel.
In summary, in the existing full-lamination bubble defect maintenance process, especially the full-lamination OCA, OCR and SCA process is particularly prone to bubble defects in the large-size full-lamination field, and needs to be disassembled and reworked, even the SCA cannot be reworked after being cured, secondary defects are particularly prone to being generated in the disassembling process, the SCA needs to be directly scrapped and needs to be completed by adding new equipment matched with the disassembling process, the disassembling process is completed by utilizing the principle that low-temperature glue materials are not adhered, other adhesive materials are also prevented from being adhered and falling off, and rework operation cannot be completed efficiently and high-quality. The prior art has the condition that disassembly cannot be carried out or only disassembly rework can be adopted aiming at the bubble defect after the display is completely attached, and the problems of fragments and the like easily occur in disassembly rework.

The basic principle is that through the matching of the detection sensor (probe) and the movement of the measurement space axis, the discrete space point position of the measured geometric element is obtained, then through certain mathematical calculation, the analysis fitting of the measured point (point group) is completed, finally the measured geometric element is restored, and on the basis, the deviation between the measured geometric element and a theoretical value (nominal value) is calculated, so that the inspection work of the measured part is completed. This application detects optical cement membrane surface through cubic element measuring apparatu to computer data processor, the quick accurate measured value that calculates of ability. The traditional measuring mode is replaced, the inspection accuracy is improved, and the high-precision product can be inspected by one hundred percent. Meanwhile, the inspection time, the inspection cost and the inspection manpower are greatly reduced, and the measurement efficiency is improved.
By adopting the technical scheme, the maintenance method is simple, and the material loss caused by disassembly and the product defect caused by secondary processing are avoided; the defects of the full-lamination product can be perfectly repaired, and the problems of low yield and high material cost of large-size full-lamination disassembly are particularly and remarkably solved. Meanwhile, because the bubbles in the liquid glue are removed before injection, the liquid glue injected to the defect part can be prevented from containing bubbles, and the maintenance quality is obviously improved; and this application has avoided causing bigger destruction because of manual operation error through automated control repair tools, has greatly solved the economic loss that the full laminating bubble of jumbo size brought.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
