Laser marking
The laser marker gives every board its identity. Everything recorded later on the line hangs on this one code, so the station checks that it is unique and readable before the board moves on.
Where the data comes from
- Marking head
- Writes the code; the program and the mark time come from here.
- The code on the board
- Read back and graded before the board leaves the station.
- Operator screen
- Shows the work order and the last serial, so a restart never reuses a code.
What we record at LM-1
Example values from the demo board KRZ-0917-00042. The source says where each fact comes from: the machine itself, a scan, an operator or the MES.
| Fact | Example | Source |
|---|---|---|
| Serial number | KRZ-0917-00042 | MES |
| Code type and size | DataMatrix 18 by 18 | Machine |
| Panel and position | Panel P-0917-007, board 3 of 4 | MES |
| Fact | Example | Source |
|---|---|---|
| Mark time | 06:42:18 | Machine |
| Marking program | KRZ-CTRL-01 C | Machine |
| Verification grade | Grade A | Scanner |
| Fact | Example | Source |
|---|---|---|
| Work order | WO-2291 | MES |
| Operator and shift | Shift B | Operator |
Checks at this station
Rules the station applies before a board moves on. Which ones run on your line is agreed with production and quality.
- No duplicate serials
- A code that already exists in the record is refused before it is marked.
- Readable before it leaves
- The mark is read back and graded; a code below the agreed grade stops the board here.
- The right program
- The marking program must match the product of the running work order.
In the manufacturing record
This is the line the station adds to the record of the board, the same record that follows it through the whole line.
