step A3: when a Mini LED panel conveyor belt (1) conveys a Mini LED panel to the lower part of a laser detector (11) and a laser range finder (12), after the laser detector (11) detects the Mini LED panel, the laser range finder (12) is used for detecting the distance from equipment to the plane of the Mini LED panel, and at the moment, distance information is sent to a microcomputer (10);
step A4: after the microcomputer (10) receives the distance information, the traversing assembly (901) provided with the positioning mechanism (9) is controlled to carry out position traversing on the light source receiver (8), so that fine adjustment of the focal height positions of the light source emitter (7) and the light source receiver (8) is realized, and the equipment is enabled to be finely adjusted to an optimal detection position;
step A5: the microcomputer (10) controls the light source emitter (7) to emit a light source, the light source irradiates on the Mini LED panel to be reflected and is received through the light source receiver (8), the light source receiver (8) transmits the received light source information to the microcomputer (10) to be calculated, and further optical detection of the Mini LED panel is achieved;
step A6: when the detection result is unqualified, the microcomputer (10) controls the electric push plate (13) to work, and unqualified products are pushed out of the Mini LED panel conveyor belt (1) and separated from the qualified Mini LED panel.
