Advanced Automated Dispensing Cabinet Design
Budget: $30 – $250 USD
I am seeking a high-level Mechanical Engineer to develop the complete production-ready engineering for an automated liquid dispensing cabinet. This project requires precision CAD files optimized for laser cutting and CNC bending (1.5mm plate).
The Core Challenge:
The unit must manage a high-density internal layout for 6 independent products, each stored in 40L drums. The total operational load is approximately 300kg.
Key Technical Requirements (Z-Axis Layout):
Structural Base (0-150mm): Engineering of a reinforced chassis to support 6 independent weighing stations (HX711 load cells) and 4 heavy-duty industrial wheels.
Storage Zone (150-850mm): Space optimization for 6x40L drums arranged in 2 rows of 3.
Pumping System: Design of lateral racks to mount 6 diaphragm pumps (0142HD) vertically on the side walls at 750mm height.
Material Strategy: Main body in 1.5mm Galvanized Steel; however, the Filling Niche (900-1300mm) must be a separate sub-assembly in Stainless Steel (AISI 304).
Service Access: The design MUST include double access (full-size front and rear doors) to allow maintenance of the back-row drums and pump manifold.
Electronics Isolation: A sealed "Technical Hub" at the top (1300-1750mm) for CPU, Arduino, and Power Supplies.
Deliverables (14-Day Timeline):
Parametric Files: Native SolidWorks or Fusion 360 files.
Fabrication Pack: 1:1 DXF/DWG flat patterns (adjusted for 1.5mm K-Factor).
Complete BOM: Detailed list of all fasteners, hinges, and industrial components.
Assembly Guide: Exploded views and technical PDF drawings.
Selection Filter (Required to bid):
To be considered, you MUST:
Start your proposal with: "PRECISION MANUFACTURING".
Briefly explain your strategy for ensuring the 6 load cells (scales) provide accurate readings within a compact sheet metal chassis.
Confirm you can provide visual progress updates every 48 hours.
