【正文】 nd 2 tables low machine utilization. 3).Overall using 24sec to finish 2 process. Process : Bearing and shaft pressing on die casting Improvement Action Kaizen Item 1).By bining both fixture into one time press fixture. 2).After implemented save a air press machine and one production table. 3).Overall using 20sec, machine utilization increase and save RMB6700 (air press). After Improvement Improvement Action Kaizen Item Before Improvement After Improvement Process : Motor and gear box lock pin assembly 1).Assembly gear box lock pin into motor by using vertical hand pressing method. 2).Difficult to centralized both lock pin into motor. 3).Assembly time 14sec. 1).Change the assembly fixture to horizontal assembly so that the operator can easily centralized the pin. 2).Assembly time 8sec. Process : Battery balance tester Before improvement needed to cover both top and bottom cell before running the test Modified the bottom cell cover so that do not need to use top sell cover. Improvement Action Kaizen Example Before Improvement After Improvement PCB cover block the soldering operator visual caused difficult to solder and slow. After study and change the soldering method which can eliminate the PCB cover. Process : PCB soldering Improvement Action Kaizen Example Before Improvement After Improvement Main Tools cost : Fixture modification cost RMB500 Saving : Productivity up % after improvement Annual man hour required 57401hWorker hourly salary Productivity up %=RMB103188 (USD14868) Cost Count Labor Cost: 125981500=RMB 125481 Total Saving ＄ 18080 (USD) Battery Line Saving : Productivity up % after improvement Annual man hour required 19014hWorker hourly salary Productivity up %=RMB22793 (USD3284) Line Setup Model Changeover 接 著 式 轉(zhuǎn) 拉 生 產(chǎn)
