Research On Improvement Of OEE Of A Company Based On TPM

For soft-bag lithium battery manufacturer,because equipment assets account for a high proportion of total assets,the level of equipment management directly affects the achievement of high-quality,low-cost and fast delivery goals.The comprehensive efficiency of equipment is an important index for evaluating the level of equipment management.The higher the comprehensive efficiency of equipment,the stronger the equipment management ability of the company.Through OEE(Overall Equipment Effectiveness)statistics and analysis,all aspects of equipment management problems can be fully exposed,which is conducive to improving the use and maintenance of equipment,thereby eliminating waste,tapping production potential and improving production efficiency.TPM(Total Productive Maintenance)is a system-wide preventive maintenance process,based on the participation of all personnel,to pursue the limit of production system efficiency as the goal,to achieve the continuous improvement of equipment OEE equipment maintenance and maintenance management system.Based on the research and analysis of TPM equipment management theory,drawing on the successful experience of enterprises implementing TPM management of equipment,combining with the actual situation of equipment management investigated and analyzed by A company,this paper introduces TPM management of equipment into equipment management of A company,and takes OEE as the evaluation index of TPM management effect.The main equipment of four main processes of A company is selected as the research object.The data before TPM implementation is collected and sorted through Andon system.The OEE of the equipment is calculated and analyzed.The two most important factors affecting OEE of A company are found out,which are type change adjustment and equipment failure shutdown,and the detailed analysis is made.SMED(Single Minute Exchange of Die)is adopted to improve the loss of type change adjustment,and self-maintenance is used to improve the loss of equipment failure.The TPM management system of the important process equipment of A company was constructed to improve the equipment management level of the company,ensure that the company can manufacture high-quality and low-cost products to meetcustomer needs,and provide reference for soft-bag lithium battery industry enterprises.Through the study of TPM,it can make enterprises gain economic benefits,promote the healthy development of corporate culture and increase market share.If many domestic soft-packed lithium battery enterprises can use TPM management,they can expand the application scenario of lithium battery and promote the establishment of a friendly and resource-based society.
