SMT placement machine production process will certainly have the problem of changing materials during production. If there is no strict standard process, it is likely to cause the problem of wrong material loading, which will be a fatal defect and cause fatal error defect of batch products. SMT mounters supplier Dafton-SMT here to share a detailed basic process.
1. When the feeder is out of expectation, the machine alarms, and the operator cancels the alarm according to the machine prompt.
2. SMT operators patrol to find out the station to receive materials.
3. Take out the Feeder which is short of material and take down the used tray.
4. SMT Mounter operator takes materials from the corresponding station on the material rack according to the station position.
5. The operator will check the removed material with the station number table to check whether the specifications and models are exactly the same. If there is any abnormality, please take the material again.
6. The operator checks the new tray with the old one, and checks whether the specifications and models of the two trays are exactly the same.
7. The operator shall check whether the material description on SMT Mounter is consistent with the material tray.
8. In case of any abnormality in the above check, SMT Mounter operator shall immediately inform the assistant puller and stretcher for treatment.
9. Cut the materials on the old and new trays, take samples from the new trays, and connect the materials on the old and new trays.
10. Take a piece of material just loaded with Feeder and paste it on the refuelling record sheet, and fill in the refuelling time, operator and other relevant information.
11. Install feeder back to SMT Mounter according to SMT placement machine position. change the material once and fill in the refueling record (including bulk material).
12. SMT Mounter operator informs IPCQC to check the material and test, and change the material once and check it once.
13. IPQC shall check whether the materials are correct and whether the station position is correct according to the station number table.
14. The SMT Mounter can only be started up for production after the above refuelling operation is verified.
