Bun Etcher

PRI: Katie Berus Rev:01 Date:4/22

At the end of the phase the Bun Etcher was ready for its final assembly with the Bun Pusher Downer and the Bracket piece. These pieces were attached to the printer with the soldering iron and fan to complete the assembly. Testing was then done on the final assembly to check that all parts were working correctly as shown in the test results section.

The final assembly of the Bun Etcher with the bun pusher downer and the soldering iron bracket can be seen in the picture below.

Burger Elevator Status Update, Drawings, and Assembly Documents

At the end of the previous phase, this subsystem was fully complete, barring final adjustments to flag positions, which was completed once the grill and spatula systems had been installed. One cutoff sensor was removed from the design, since one sensor was determined to be sufficient to accurately position the elevator in front of the pneumatic actuator. Scripts to allow the RasPi to operate the elevator automatically are also complete.

Grill Status Update, Drawings, and Assembly Documents

Last phase, an additional 3D printed part was necessary to allow the string to spool around the electric motor's shaft. This part is known as the "Spooling Disk" and is shown in the photo below.

Spatula Status Update, Drawings, and Assembly Documents

The burger pusher remains the last subsystem required to meet the "burger cooking" function of our overall design. The actuator has been mounted to the table. The burger pusher will be fabricated and installed in the next phase.

Pick-and-Place System Update, Drawings, and Assembly Documents

The system underwent some small last-minute changes after assembly and testing showed there were some hardware faults. The chosen stepper motor for the y-axis was not able to provide enough torque with the chosen controller, so the motor was upgraded from a NEMA17 motor to a NEMA24 motor with a 12V 1.5amp power supply. This was a simple swap utilizing the 80-20 rail as a universal mounting location. Additionally the vacuum bracket guide rail hole was enlarged to utilize a linear roller bearing instead of the originally designed bushing. This allowed for a more consistent action with less friction for a more reliable z-axis operation. The vacuum hose and bearing were attached with hot glue to the vacuum bracket.

At the end of the previous phase, the assembly system was 85% completed with the removable delivery plate in place. The rack and gear sub-system installed onto the push plate, overall height as adjusted based on the requirements of other sub-systems, motor position adjusted, and the rack guiding bracket had been installed in this phase. Final assembly of the Assembly Station can be seen in the picture below.

Customers can order through our website, to add a custom image of their choosing.

The edit feature was implemented to drown out background noise so that our bun etcher could properly draw the picture onto the bun. The customer first uploads the image onto our server, then we send the picture to clipping magic when the user decides to press the edit picture button.

The Clipping magic editor tool was used, as can be seen below.

Plans for Wrap-up

PRI: Katie Berus Rev:01 Date:4/23

To conclude the project, the team needs to hand over the prototype to our sponsor, RIT IEEE. We will also need to make sure that all of the documentation is handed over as well, so that IEEE can run the machine and can make any changes that they would want to in the future.

Also, the team needs to clean up the workspace on the MSD floor and complete our final Gate Review with our guide.
