All raw materials should be inspected according to AQL Critical:0 Major:1.0 Minor:2.5 level Ⅱ.About the clock mechanisms, we will use a quartz detector to detect the time accuracy(≤±30 seconds per day) and consumption current(step clock mechanism≤140uA, sweep clock mechanism≤180uA, alarm clock mechanism≤160uA).
Clock Manufacturing Process
Brush the glue evenly on the plastic dial.
Install gasket and fix clock mechanism on plastic dial with nut.
Align the clock dial face to the position of 6 o ‘clock and 12 o ‘clock and stick it on the surface evenly.
Install hour, minute and second hands on clock mechanism shaft, keeping them parallel to ensure time accuracy.
Clean up clock dial face and put a clean glass lens on clock dial face plate
Check the existing appearance and functions of the products without outer frame, then flow into the outer frame station when they pass the inspection, and return to the corresponding station for maintenance when they fail the inspection.
Install outer frame on clock dial face plate, fix the back with legs, get a clock at this time
clean the appearance of the clock with a clean white cloth
QA check the appearance and function of the clock, and then flow into the packaging station; NG product will return to the corresponding station for maintenance
pack the clock into bag, box and export carton according to the packaging requirements.
