2. The laser marking machine of claim 1, wherein the marking machine body comprises:

the device comprises a frame, a detection device and a control device, wherein the frame is provided with a feeding station, a marking station, a detection station and a discharging station;

the marking mechanism is arranged on the rack, is arranged above the conveying mechanism and corresponds to the marking station, and is used for performing laser marking on the product and forming an identification code when the product is positioned at the marking station;

3. The laser marking machine of claim 2, wherein the recirculation track is disposed below the conveyor track.

4. The laser marking machine of claim 3, further comprising an elevating mechanism provided at both ends of the conveying mechanism to switch the height of the tray mechanism so that the tray mechanism can circulate on the conveying rail and the reflow rail.

5. The laser marking machine of claim 4, further comprising a size detection mechanism disposed between the marking mechanism and the feed mechanism.

6. The laser marking machine of claim 5, further comprising a flatness detection mechanism and a flipping mechanism, the flatness detection mechanism and the flipping mechanism being disposed between the feeding mechanism and the size detection mechanism, the flatness detection mechanism being proximate to the feeding mechanism, the flipping mechanism being disposed between the flatness detection mechanism and the size detection mechanism.

7. The laser marking machine of claim 6, wherein the turnover mechanism comprises a jaw assembly and a clamping assembly, the jaw assembly is provided with a suction cup gripper for absorbing the product; the clamping assembly is rotatably arranged on the side of the clamping jaw assembly and comprises a support, a rotating cylinder, a clamping piece and an unlocking piece, and the rotating cylinder is arranged on the support; the clamping piece is connected with the rotary cylinder; the unblocking piece is arranged on the side of the clamping jaw assembly and is located between the clamping assembly and the clamping jaw assembly.

8. The laser marking machine according to claim 7, further comprising a jacking mechanism and a limiting mechanism arranged in the conveying mechanism, wherein the jacking mechanism and the limiting mechanism are matched and applied at the same station, the jacking mechanism is positioned below the tray mechanism when the conveying track is in circulation, and the jacking mechanism is applied to adjust the position height of the tray mechanism when the tray mechanism is in circulation on the conveying track; the limiting mechanism is arranged behind the jacking mechanism along the conveying direction of the conveying track, and can be switched between an initial position and a limiting position in a lifting mode.

9. The laser marking machine of claim 8, wherein the tray mechanism further comprises a tray body and a Y-axis spring loaded hold down assembly, the plurality of positioning slots being provided in the tray body; the Y-axis compression assembly with the spring comprises a Y-axis compression piece and a Y-axis unlocking handle, and the Y-axis unlocking handle is used for controlling the Y-axis compression piece to compress or loosen.
