Abstract
The invention relates to an on-line detection control system and control method thereof for powder coating thickness. The on-line detection control system comprises a programmable logic controller (PLC) characterized by being conducted with an optical fiber sensor; when an empty can enters a detection area and the optical fiber sensor detects the empty can, the PLC enables a laser sensor and a laser signal amplifier to enter an operating mode; when the empty can enters a laser sensor area, the laser sensor sends laser signals for detecting the coating thickness of the empty can; when the empty can is qualified after detection, the qualified empty can directly enters the next process for baking; and when the empty can is disqualified after detection, the laser signal amplifier outputs disqualification signals to the PLC, the PLC outputs stop signals to a host machine to stop feeding, and simultaneously an actuating mechanism delivers the disqualified empty can to a rejection collecting area. The on-line detection control system provided by the invention can detect empty cans with thin powder, local missed coating and no powder coating on line, and accurately discharge the disqualified empty cans, thus greatly improving the production efficiency.
