s3, in the process that the bidirectional laser marking mechanism marks the product to be marked, which is blocked on the first side, the other product to be marked is placed on the first conveying line on the second side, and the other product to be marked is conveyed along a guide channel formed by the two limiting rod mechanisms; the two positioning and blocking mechanisms on the second side block a product to be marked at a marking station of the first conveying line on the second side, and the bidirectional laser marking mechanism marks another product to be marked on the second side;
s4, when the marking of the product on the first side is finished, the two positioning blocking mechanisms retract to the original positions, the product on the first side is conveyed along the guide channel formed by the two limiting rod mechanisms continuously, and the product marked on the first conveying line on the first side is transferred to the second conveying line by the transfer manipulator;
and S5, when the marking of the product on the second side is finished, the two positioning blocking mechanisms retract to the original positions, the product on the second side is conveyed along the guide channel formed by the two limiting rod mechanisms continuously, and the product on the first conveying line on the second side is transferred to the second conveying line by the transfer manipulator.
