[FreeCAD] Vacuum Lifting System - Venturi Type - Final Year Project

Last crawled date: 1 year, 11 months ago

PROJECT REPORT : https://mega.nz/file/7E5CxCiL#JFj6YiENNaBOzImBemI9ndOQH7nCULL36oFwGbRnMRU

This is my Final Year Project at the university. The objective is to lift a 30kg Class D Gypsum Block, and this end-effector can be used by a robotic arm to build a partition wall.

The design was carried out almost entirely in FreeCAD. A2Plus workbench was used to create the assemblies.

The following parts were used for this project:

LIFTING FUNCTIONALITY:
1. Vacuum Ejector : CV-25HS (1 Piece)
2. Suction Cups: Flat, 125mm - SMC ZPT 125-H (3 Pieces)
3. Filter: SMC ZFC-200 (3 Pieces)

SAFETY FEATURE:
1. Ropes: 4mm thick, 0.9m long, terminated at both ends.
2. 40mm long Aluminum Profile to guide screw
-Function: Locks and releases the rope of the safety feature

3. Solenoid Actuator: 10mm stroke, 12V DC
-Function: Electrically-operated Lock and Unlock mechanism for the removable end of the rope

4. Arduino: Controls the Solenoid Actuators by buttons and separately by magnetic reed switches

5. Magnetic Reed Switch: 10mm x 1.8mm.
-Function: Magnet attached to rope termination. Used by Arduino to semi-automate the locking process. The rope can be locked by the operator with just one hand.

6. Relay Module: 8-channel, used to operate the 12V solenoid actuators.

END EFFECTOR FRAME:
1. 2020 Aluminium Profiles : 55cm, 65cm, 38cm, 16cm, 4cm
2. Aluminium Plate: Custom-ordered, fits SMC ZPT direct-mount fittings. Through holes without threading.

CREDITS:
Two parts were not designed by me
1. Zachary Nash designed the 8-channel Relay Module drawing I used
2. Sedanur Kirci designed the Arduino Uno drawing I used.
