碩士 === 中原大學 === 機械工程研究所 === 103 === Touchscreen panel is combined with display panel and input device as 2-in-1 application becomes the high-end fashionable electronic products. Resin dispensing and laminating processes are the two main functions concerned for designing automation equipment. Optimistic pattern layout of optical resin, alignment calibration, as well as air gap controls between the cover glass and the touchscreen are investigated in this thesis. Design of the equipment includes functional concept, mechanism layout, transmission mechanism, visual alignment and programmable firmware of servo controller. A prototype equipment is built to carry out resin dispensing and laminating testing and performance verification finally. Via the practical testing with enough experimental results, it is found that the ambient temperature is quite influential to the dispensing viscosity of the fluid dispenser. Dispensing needle syringe needs to be applied with thermostatic system. The add-in temperature control is able to effectively stabilize the dispensing glue amount. The adhesive coated surface is not allowed to be made with randomly interleave pattern. In order to line up the dispensing coated edge with the adhesive surface pattern, the dispense work needs to lay out the degassing channel in order to avoid from the retained air bubbles between the laminating glass substrate and touch sensor. In case of effective control on the above process parameters, improving productivity and yielding rate of the laminating process is achieved. The developing technique in this article is instrumental to design an automatic equipment of high-speed laminating process that can enhance the production efficiency.
