| Abstract [eng] |
To create an automated adhesive dispensing system using a 3D printer, a detailed study of dispensing methods was performed. Most common methods, such as syringe-type, contact transfer, and non-contact dispensing methods, were analyzed to understand which of these solutions would be the perfect fit. Through methods such as the design selection matrix and defining the necessary system requirements, goals were set that the system should achieve. The volumetric dispensing method was selected because this system matched the needed viscosity ranges and precision on the bead width that was necessary to achieve. A deep dive into the components was also performed to understand the factors of the geometrical code and the importance of configuring the system correctly. The existing 3D printer platform components were defined to understand what modifications need to be made. Then the pneumatic system was determined what devices should be added to sustain the supplied pressured air. The old tool of the 3D printer was removed, and the design of the parts that will be included in the system was made. The components that were printed included the mounting, push, and holding parts. Finally, the overall system was assembled and calibrated to ensure that the system worked and the movement was accurate. With the use of geometrical code, the movement of the dispenser was defined and tested. Programs were created to follow the desired path of the part that was provided and to perform the automated dispensing process. |
