Mounting Line Work Instruction Using Face Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators in mounting machines face inefficiencies due to the need to manually input and select work items, leading to wasted time and reduced work efficiency.
Innovation Solution
A work management device that uses face authentication sensors to detect operators and automatically instruct them on work items, eliminating the need for manual input and selection, and updates work item data based on completed tasks to ensure only unperformed items are displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator manually inputs and selects work items, then the operator can manage work items flexibly, but the operator burden increases and work efficiency deteriorates
Solution Approach 1:
The system performs automatic operator identification using face recognition technology, eliminating the need for manual ID input. The work items are automatically assigned and displayed based on the detected operator, allowing the system to serve itself rather than requiring operator intervention for item selection and input.
Solution Approach 2:
The manual mechanical process of operator ID input and work item selection is replaced with an automated optical recognition system. The face authentication sensor captures images, the control unit processes them to identify operators, and automatically retrieves and displays appropriate work items, substituting human manual operations with automated mechanical and computational processes.
2Reliability
If the control device displays detailed work procedures for low-level operators, then work errors are reduced, but the system complexity increases
Solution Approach 1:
The system provides differentiated work procedure displays based on individual operator characteristics. Each operator receives customized work instructions tailored to their skill level, with detailed procedures for those who need them and simplified displays for experienced operators. This localized adaptation ensures appropriate information density for each user without requiring all operators to receive the same level of detail.
Solution Approach 2:
The system pre-stores work procedure data with varying levels of detail in the storage unit. When an operator is identified, the control unit automatically retrieves the appropriate level of procedural detail based on the operator's profile and current task requirements, preparing the customized display information in advance before the operator begins work.

AI summary
There is provided a technology for reducing a burden on an operator performing work in a mounting machine and improving work efficiency more than in the related art. The work management device manages electronic component mounting line with a plurality of mounting machines. The work management device includes an operator information memory section that stores operator information regarding a plurality of operators, a work item memory section that stores a work item group performed by the operator, a plurality of operator detection sections, and one work instruction section or a plurality of work instruction sections. The operator detection sections are installed at a plurality of spots of the electronic component mounting line and detect the operators near the spots. In a case in which the operator detection section detects the operator, when operator information regarding the operator is identical to operator information in the operator information memory section and the work item group of the work item memory section includes one work item or a plurality of work items which are able to be performed by the operator detected by the operator detection section, the work instruction section instructs the operator detected by the operator detection section in one work item or a plurality of work items selected from the one work item or the plurality of work items.
