How Often should the laser box be cleaned?
Every 6 hours
The engineering requirements, used for judging the acceptability of a particular product/service based on product characteristics, such as appearance, performance and size.
What am I?
Specification
What's the assembly process flow?
Laser cutting, winding, tab flattening, Hi-pot 1, Disk welding, taping, Hi-pot 2, Can loading, can washing, Jelly Roll insert, Positive terminal welding, Helium leakage testing, rivet welding, negative terminal welding, can grooving, Hi-pot 3, X-ray overhang
What are the 4 Major processes in winding
Load the slit roll, Laser cut tabs into foil, wind the foils into jelly rolls and tab flattening
What's the purpose of the Hi-pot?
To ensure the anode and cathode foils are not touching to prevent short circut
What are the functions of the MES
The MES tracks the Winder’s production processes, including production rates, cycle times, and machine status
the “beat” of customer demand—the time required between completions of successive units of end product
What am I?
Takt time
How far away are the two set of sensors from the electrode or separator edge
20-30mm
Explain the difference between Positive terminal welding and Rivet Welding?
Positive terminal welding is when we weld through the open section of the positive terminal to the cathode disk of the Jelly Roll. Rivet welding is when we weld the cathode disk in 4 spots and around the edge of the can.
Where cells are placed and stored between areas
magazines
What do you do before placing the rolls into the machine to ensure proper identification or tracking?
Scan the roll
What is the ideal state for just-in-time production where the practice is to make one part and move one part, at the pace of takt time to meet (internal or external) customer demand?
Continuous Flow
What type of powder goes on the bottom of the Seperator?
Ceramic Powder
What is the purpose of the CDD Cameras
Defect Detection and Measurement accuracy
- means “signboard” in Japanese and translates to “signals” in Lean manufacturing
Kanban
Blue tape on the jelly roll produce how many cells?
