Development of Automatic Grease Injection System

Abstract

The purpose of developing an automatic injection system is to study, develop, and improve the efficiency of the system. Data has been collected from production trials conducted on the production line of Denso Thailand. Tools used include an assessment of production efficiency and group meetings with stakeholders.

The study found that the main problem in the production process was due to incorrect worker processes, resulting in delays. Researchers designed a new thermal inspection system using the ICAD SX program to design parts and graphs, create 3D models to explain usage and cost, and create 2D designs for work orders and illustrations. A characteristic feature checking tool was created for the components according to the model. The average performance evaluation of the automatic injection system was 4.35, with a standard deviation of 0.56, indicating that the system is effective and usable. The design aspect had the highest average score of 4.64, with a standard deviation of 0.28. Production time was found to be 17 seconds less per unit with a 100% injection rate from the production process. This was confirmed by machine certification, ensuring no wasted work. reducing the number of employees in a production process from 2 to 1 can result in a 200% increase in efficiency, as well as an increase in annual value of approximately 203,000 baht when factoring in both labor and increased production.
