Overview of Status of Analysis, Design, Fabrication, Tests, etc.
CAD modeling has began on major components of the final machine design.
A data logger will be purchased this week and temperature testing will commence.
Accomplishments from Previous Week
A new design idea was generated that would combine the two components required for the heat-staking process, the base plate and the torque lever, into one automated process.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finish code for controlling nesting mechanism (Matt).
Research and purchase a linear actuator (Gerui).
Purchase data logger and observe thermocouple temperature in 8 hour intervals (Hugo).
Finish CAD model of nesting mechanism (Barbara).
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
An email was sent to our sponsor, Dave Gillett, on April 9, 2020.
In this email, the concept to combine both the component that actuates the heat stamp and the component to move the nest was presented to Dave. The details of how this would be implemented (using a linear actuator) were also described in the email. His comments were positive and he believes the idea is practical.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
A meeting with our instructor, Dr. Ghazinejad, and one our TAs, Rishabh Khanna, was held on 4/9/2020 via Zoom. The comments were:
Using a thermistor would be more practical than a thermocouple in the case of our project because of the duration of time in which the machine must operate.
Provide more schematics when describing projecy to ensure a better understanding of the ideas from the audience.
Consider a mechanism to insert the plastic disks after each assembling and to reel the adhesive webbing.
Risks and Areas of Concern
One area of concern is devising a way to ensure that the linear actuator will consistently and constantly apply 90 pounds of force for 10 seconds to heat stake the plastic disks to the adhesive webbing.
Another area of concern is the webbing alignment system. We are simulataneously working on the webbing alignment and the heat staking mechanism as we believe these will be our greatest challenges.
Schedule
The Gantt chart was last updated on 4/10/2020 and is currently up to date.
The upcoming goal set for 4/12/2020 is to complete the code for controlling the nesting mechanism and to purchase the actuator and finish the CAD model of the nesting mechanism by 4/13/2020.
