Abstract
The invention discloses a verifier for a printed circuit board. The verifier comprises a stander and a delivery mechanism, a scanning mechanism and a main control system which are arranged on the stander, wherein the scanning mechanism comprises an image processor positioned on the upper side of the delivery mechanism and a strip source positioned below the delivery mechanism; and the strip source is an LED lamp. The invention also discloses the workflow of the verifier, which comprises the following steps of: starting a transmission system; detecting a working state of the strip source; scanning a standard circuit board to generate a standard file and store the standard file; loading the standard file to detect circuit boards on the delivery mechanism; comparing detected contents with the standard file to obtain boards in good condition and boards in poor condition; and taking out and storing the boards in good condition and the boards in poor condition respectively. When the verifier works, that the strip source is frequently replaced due to optical attenuation is avoided and the step of detecting the working state of the strip source is added before scanning the circuit boards, so the condition of starting the verifier as usual when the strip source cannot work is avoided.
