s2, when the specification of the circuit board is smaller than a standard value, the detection element on the detection frame (5) supplies power to another electrified spring (67) through data transmission by using the controller, the electrified spring (67) contracts to drive the movable frame (63) connected with the slide bar (66) to slide towards the direction close to the third conveyor belt (46), at the moment, the space on the left side of the upper end of the connection plate (61) is reduced, and the circuit board slides onto the third conveyor belt (46) along the movable frame (63) to be conveyed;
s3, when the situation is not the precondition of the steps S1 and S2, the circuit board passes through the detection frame (5) in the conveying process of the first conveyor belt (44), the detection element on the detection frame (5) detects the circuit board in the abnormal product, the detection element used for controlling the hydraulic cylinder (81) to stretch and retract on the detection frame (5) drives the hydraulic cylinder (81) through data transmission by using a controller, the hydraulic cylinder (81) contracts and drives the connection plate (61) to deflect downwards, the third fixing rod (69) on the side wall of the connection plate (61) slides in the second sliding groove (72), the third fixing rod (69) extrudes the fixing block (75) and the first movable plate (74), so that the first movable plate (74) moves towards the inside of the second sliding groove (72) and extrudes the spring (73) to contract, and when the third fixing rod (69) is static, the first movable plate (74) clamps the third fixing rod (69) under the elastic force of the spring (73), the position of a third fixing rod (69) is limited, and the circuit board directly slides into a collecting groove (82) for collection;
s4, the more the abnormal circuit board is accumulated after falling into the collecting tank (82), the heavier the weight on the second movable plate (84), the greater the pressure of the second movable plate (84) on the pressure sensor (83), and when the pressure on the pressure sensor (83) reaches a set value, the alarm (86) is started under the action of the CPU and the controller, so that an alarm is given out.
