[0021] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0022] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0023] See Figure 1-5 The single-window flip laser engraving fixture shown includes two symmetrically arranged lifting mechanisms 1. One lifting mechanism 1 is equipped with a rotating unit, and the other lifting mechanism 1 is equipped with a driven shaft seat. A first connecting plate 802 is installed at the end of the rotating unit facing the driven shaft seat, and a second connecting plate 702 is installed at the end of the driven shaft seat facing the rotating unit. A carrier plate 401 is connected between the first connecting plate 802 and the second connecting plate 702. A rectangular window 2 is provided in the middle of the carrier plate 401. Multiple side stops 404 and clamping cylinders 408 are provided on the carrier plate 401 at both sides of the rectangular window 2. At least one end stop 411 is provided on the carrier plate 401 at one end of the rectangular window 2.

[0024] By implementing the above technical solution, during use, after the robotic arm grabs the product 9 and places it on the fixture surface of the carrier plate 401, the product 9 is limited by multiple side blocks 404 on both sides and the end block 411 at the end. Then, the product 9 is clamped by the clamping cylinders 408 on both sides, so that the product 9 is stably fixed. Then, the carrier plate 401 is rotated by the rotating unit. Under the coordinated action of the first connecting plate 802, the second connecting plate 702 and the driven shaft seat, the product 9 is flipped. Since the engraving position of the product 9 is inside the product 9, after flipping the product 9, it can be laser engraved by the laser engraving machine above. After the laser engraving is completed, the lifting mechanism 1 at both ends carries the product 9 down. After it is lowered to a certain distance from the lower assembly line, the clamping cylinders 408 are released, so that the product 9 falls onto the assembly line. Finally, all parts return to their original positions and the next work begins. This single-window flip laser engraving fixture can complete the flip laser engraving operation on product 9. After the laser engraving is completed, product 9 can be carried to a lower position by the lifting mechanism 1 and placed on the corresponding production line for conveying, thereby improving laser engraving efficiency.
