How to Convert Paper Inspection Sheets for Injection Molding Machines into QR Codes

Original article: https://cli.im/article/detail/1833

Having used the CaoLiao platform to create equipment inspection QR codes for some time, I consulted customer support and peers in user groups to gradually implement QR codes for factory equipment. Here’s a summary of my experience to help others avoid similar hurdles.

Initially, I used platform-provided templates, but they lacked customization for our specific inspection items and workflow. For example, daily maintenance tasks involve multiple roles, yet the template only included basic pre-shift checks without tracking issue resolution or assignees. Through trial and error, I developed a solution. This guide shares my approach and suggests platform improvements for new users.

Replicating Paper Inspection Sheets as QR Codes

Our original injection molding machine inspection sheet contains:

Equipment information
Operator checklist
Signatures (operator/manager)
Issue handling procedures

First Iteration

All equipment info and checklist items were embedded in forms. Drawback: Repeated manual entry of fixed equipment details.

Second Iteration

Platform tip: Embed fixed equipment info directly in QR code content while using forms for variable data.
Key improvements:

QR code name auto-populates in exported data
Attach equipment photos/manuals in content
Added image upload and GPS location modules

Third Iteration

Integrated three workflows into one QR code system:

Maintenance Checklist
- Multi-select options for routine tasks (oil refill, resin cleaning)
Repair Records
- Photo documentation of issues
Centralized Equipment Profile
- Linked daily inspections, maintenance, and repair records
