10. A method for implementing a device for automatically detecting impedance of a magnetic product according to any one of claims 1 to 9, characterized in that: The following steps are involved: (I) The production staff uses the suction plate to neatly suck the magnetic products out of the wooden tray and put them on the wide belt body. The disengagement cylinder pushes the wide belt body to contact the feed belt. The products on the wide belt body are transferred to the feed belt. After the photoelectric detection on the feed belt detects that the product is in place, the disengagement cylinder drives the wide belt body to reset, so that the wide belt body is separated from the feed belt; (2) The feed belt transfers the product to the retrieving belt. When the in-place optical fiber on the retrieving belt and the corresponding photoelectric devices on both sides light up at the same time, the transverse clamping mechanism is activated; (3) The transverse clamping mechanism places the product on the material taking belt on the placement seat on the placement position of the impedance measuring mechanism, and the rotary cylinder rotates to turn the product to the test position. The upper probe cylinder drives the upper probe down to contact with the lower probe, forming a closed-loop test impedance; (IV) After the impedance test is completed, the rotary cylinder rotates to rotate the tested product to the placement position, and the transverse clamping mechanism takes out the tested product and puts in the next untested product; (V) The transverse clamping mechanism places the tested products on the defective product conveying belt body. The qualified products are transmitted backwards, and the defective cylinder does not work; for the unqualified products, the defective cylinder works to push the products onto the defective product conveying belt; (VI) Products that fail the test are transported backwards and arranged on the defective product conveyor belt. When the in-place optical fiber on the defective product conveyor belt continuously detects the product, the pusher mechanism moves to push the defective products neatly onto the defective product arrangement board, and then they are manually taken out and retested; (VII) Products that have passed the test are transmitted to the good product discharge belt body. When the optical fiber in place on the good product discharge belt body continues to detect the product, the pushing mechanism will move to push the qualified product in. The good product discharge mechanism will push the product into a multi-layer receiving box, which will be taken out manually later.
