A laser engraving machine can engrave fine text, patterns, two-dimensional codes and other information on the surfaces of various materials by controlling the movement trajectory and energy output of the laser beam. Laser engraving technology has the advantages of high precision, high efficiency, environmental protection, energy saving and wide applicability, and has been widely applied in fields such as industrial manufacturing, packaging and printing, and artistic creation. In industrial manufacturing, laser engraving technology can be used for product identification and traceability, improving the traceability and anti-counterfeiting capabilities of products. In the packaging and printing industry, the laser-engraved marks have the advantages of wear resistance, scratch resistance, and non-fading. With the continuous development of technology, the application prospect of laser engraving technology will be broader.

[0003] Laser engraving is generally collectively referred to as laser marking, but usually manual feeding is required for laser engraving. Conventionally, an article is placed into a fixed mold manually to ensure that the article to be engraved does not tilt. In the prior art, the automatic feeding equipment usually engraves in batches, and several articles are placed into the mold through an assembly line. However, after laser marking, the high temperature generated will cause the articles and the mold to become hot, so that the subsequent packaging operators will get burned when taking the articles. To solve this technical problem, the utility model proposes an automatic feeding mechanism for laser engraving. Content of the Utility Model

[0022] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, an automatic feeding mechanism for laser engraving includes a load-bearing plate 1. A conveyor belt 2 is installed inside the load-bearing plate 1. Above the load-bearing plate 1, there is a caliper 5. Above the load-bearing plate 1, there are a first motor 3 and a second motor 4. On both sides of the first motor 3, there are cylinders 6. Above the load-bearing plate 1, there are several carrying frames 7. When in use, the item to be laser engraved can be placed in the groove reserved on the carrying frame 7. The carrying frame 7 is provided with a closing device, which can make the item closely adhere to the carrying frame 7. Then, the carrying frame 7 is placed on the conveyor belt 2. The conveyor belt 2 can drive the carrying frame 7 to move to directly below the laser engraving machine. And during the movement, the carrying frame 7 can be clamped into the inner side of the caliper 5. After the item on one side of the carrying frame 7 is engraved by the laser engraving machine, the cylinder 6 can drive the first motor 3 and the carrying frame 7 to move upward. The first motor 3 can drive the moving frame to reverse, so that the item on the bottom surface is exposed directly below the laser engraving machine. After both sides are engraved, the second motor 4 can remove the moving frame from below the laser engraving machine, increasing the number of items laser engraved at one time, and also being able to extend the time of single laser engraving and the overall speed of the production line, so that there is enough cooling time for the engraved item and the carrying frame 7, solving the problem that the subsequent packaging operator gets burned when taking the item.

[0024] The outer surface of the conveyor belt 2 is fixedly installed with a clamping block 8. The outer surfaces of both the conveyor belt 2 and the clamping block 8 are fixedly installed with the outer surface of the bearing frame 7. The outer surface of the load-bearing plate 1 is fixedly installed with a guard rail 9. The outer surface of the guard rail 9 is slidably connected to the bearing frame 7 located above the load-bearing plate 1. The clamping block 8 can keep the bearing frame 7 on the conveyor belt 2 at a fixed distance, and also prevent the bearing frame 7 from shaking when the conveyor belt 2 is running. The guard rail 9 can ensure that the bearing frame 7 will not be displaced or tilted when it enters above the load-bearing plate 1 and detaches from the bearing frame 7 of the conveyor belt 2.

[0025] The outer surface of the load-bearing plate 1 is fixedly installed with a guiding rod 10. The outer surface of the load-bearing plate 1 is rotatably connected to a threaded rod 11. One end of the threaded rod 11 is fixedly installed with the output end of the second motor 4. The outer surface of the second motor 4 is fixedly installed with the outer surface of the load-bearing plate 1. The load-bearing plate 1 can provide an installation space for the second motor 4, enabling the second motor 4 to drive the threaded rod 11 to rotate. And the second motor 4 is a servo motor, which can accurately control the rotation angle of the threaded rod 11.

[0026] A moving frame 12 is slidably connected to the outer surface of the guiding rod 10. The inner wall of the moving frame 12 is threadedly connected to the inner wall of the threaded rod 11. The outer surface of the moving frame 12 is fixedly installed with the outer surface of the air cylinder 6. The guiding rod 10 can provide a fixed moving direction for the moving frame 12, so that the moving frame 12 will not be misaligned or displaced when moving. When the threaded rod 11 rotates, it can push the moving frame 12 and the air cylinder 6 to move.

[0027] The output end of the air cylinder 6 is fixedly installed with a load-bearing frame 13. The outer surface of the load-bearing frame 13 is fixedly installed with the outer surface of the first motor 3. The output end of the first motor 3 is fixedly installed with the outer surface of the caliper 5. The air cylinder 6 can drive the load-bearing frame 13 to move up and down. When the load-bearing frame 13 moves, it can drive the first motor 3 and the caliper 5, thereby driving the bearing frame 7 to lift.

[0028] The outer surface of the bearing frame 7 is fixedly installed with a clamping block 15. The outer surface of the caliper 5 is slidably connected to the outer surface of the clamping block 15. When the bearing frame 7 moves into the area above the load-bearing plate 1, the clamping block 15 on the bearing frame 7 can slide into the caliper 5, enabling the caliper 5 to fix the bearing frame 7.

[0029] A sliding rod 14 is slidably connected to the inner wall of the load-bearing frame 13. The bottom end of the sliding rod 14 is fixedly installed with the outer surface of the moving frame 12. The sliding rod 14 can provide a fixed moving direction for the moving frame 12, ensuring that when the air cylinder 6 drives the load-bearing frame 13 to move up and down, there will be no displacement or misalignment.
