Specifically, in the width direction of the first conveying mechanism 3, the maximum width of the clamping end of the second clamping member 73 should be greater than or equal to the width of the guide rail 61, so that the clamping end of the second clamping member 73 can descend to the bottom of the guide rail 61 and clamp the product to be marked.

[0061] The working principle of the utility model is:

[0062] In the assembly process, the assembled downlight products will be sent to the loading platform 21, the flip loading component 22 clamps the product and turns it over to the first receiving groove 2321 or the second receiving groove 2322 of the rotating component 23, so that the surface of the product to be marked faces upward, the rotating component 23 rotates, and the product is sent to the feeding end of the first conveying mechanism 3, the clamping and conveying component 24 clamps the product and moves it above the first conveying mechanism 3, and the top of the product is embedded in the guide track 61, so that the product moves along the guide track 61;

[0063] When the product moves to the interception mechanism 5, the interception mechanism 5 extends so that the interception member 52 presses against the product until the previous product is marked, then the interception mechanism 5 retracts and the product is conveyed to the second conveying mechanism 4;

[0064] When the product moves to the correction mechanism 7, the interception component 72 extends to intercept the product, and the lifting drive component 71 controls the two second clamping components 73 to extend and clamp the two ends of the product in the radial direction to achieve position correction, and then marking is performed. After marking is completed, the interception component 72 retracts and the product continues to be conveyed.

[0065] It is worth noting that in Figure 7 Two states of the first clamping component 222 are shown at the same time, namely, the state when the clamping claw of the first clamping component 222 is located above the loading platform 21 and the state when the clamping claw of the first clamping component 222 is arranged opposite to the movable end of the rotating component 23.
