How to Convert Injection Molding Machine Paper Inspection Checklists into QR Codes

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

I've been using the CaoLiao platform to create equipment inspection QR codes for a while now. During this time, I've consulted the platform's customer service and asked peers in community groups. Through some trial and error, I've managed to set up QR codes for the equipment in our factory area.

Initially, I used the templates provided by the platform to create the codes, but the inspection items differed. More importantly, the daily maintenance work for the equipment is performed by different staff members. The template only included a routine pre-shift inspection. It didn't account for how to handle discovered issues or who should handle them. I figured these aspects out through my own exploration later on. Thinking that other equipment managers in the industry might face similar challenges, I decided to share my approach. Perhaps the CaoLiao platform could also consider how to help newcomers get started more quickly.

Creating QR Codes Based on the Paper Inspection Checklist

Below is the injection molding machine inspection checklist created by our company. It includes equipment information, operator inspection items, operator/supervisor signatures, and procedures for handling various situations.

First Version:

Both the equipment information and inspection items were placed directly on the form. I found it inconvenient to re-enter the equipment information every time, which led me to create a second version.

Second Version:

CaoLiao customer service informed me that fixed equipment information could be embedded directly into the QR code content itself. The content that needs to be recorded during inspections can be set up as a form. In the exported data, the QR code name is displayed, allowing identification of which equipment was inspected. Additionally, equipment photos, operating documents, etc., can be uploaded in the main content section.

I also added image and location modules to the form. When an issue is discovered, staff can directly take and upload photos, creating a verifiable record.

Third Version:

Beyond the daily inspection checklist, I also included the supervisor maintenance log and repair log within the same QR code system. This consolidates all relevant records for each specific injection molding machine in one place.

1. Maintenance Log

Used for recording routine tasks like lubrication and residue removal. This can be implemented using a multiple-choice component, where staff select all tasks performed.

2. Repair Log

Used to document each repair incident. Photos can be uploaded, which is a significant improvement over the previous paper-based system.

I associated the daily maintenance log and repair record log directly with the original injection molding machine QR code.

QR Code Template Sharing

Here is the QR code I created. You can scan it to experience the functionality. Sharing link: https://cli.im/share/xP6gtpA. Feel free to use it if it meets your needs.

Some Existing Limitations

1. Inability to Merge Exported PDFs

Currently, only individual inspection record PDFs can be exported per entry. I would prefer to export a consolidated report, for example, one PDF per month, similar to the original paper system.

2. Inconvenience for Supervisor Sign-off

The records cannot be filled out in two separate stages: first by the operator, and then submitted for supervisor confirmation and signature. I haven't found a good solution for this yet and have temporarily removed the supervisor signature requirement. If anyone has effective solutions, we can discuss this further.
