A limiting component for keeping the carrying plate 5 stable is provided on the base 1, and the bottom of the connecting shaft 53 is a square structure, and a square hole 62 is provided on the upper end of the connecting sleeve 61. The sizes of the adapting grooves 51 on different carrying plates 5 are different, and the sizes of the adapting grooves 51 on the same carrying plate 5 are the same. A bottom hole 52 is provided at the bottom of the adapting groove 51, and the laser printing head 4 is located just above the adapting groove 51.
[0019] The limiting assembly includes an annular platform 8 and a fixed bracket 7. The fixed bracket 7 is fixed to the upper end of the base 1 and is located on the periphery of the supporting plate 5. The upper end of the fixed bracket 7 is rotatably connected to the flip plate 71. The annular platform is fixed to the upper end of the base 1. Ball bearings 72 are installed on the upper end of the base 1 and the bottom of the flip plate 71. The periphery of the ball bearings 72 is against the upper and lower surfaces of the supporting plate 5. A cylinder 73 is installed between the outer side of the flip plate 71 and the fixed bracket 7. A horizontal positioning block 74 is fixed to the front side of the fixed bracket 7, and the horizontal positioning block 74 is located below the flip plate 71.
[0020] The lifting assembly includes a threaded rod 21 and a lifting block 22. The lifting block 22 is slidably connected to the support column 2. The threaded rod 21 is rotatably connected to the support column 2. The threaded rod 21 passes through the support column 2 and is threadedly connected to the support column 2. The upper end of the threaded rod 21 extends out of the support column 2 and is fixed with a rocker 23. The lifting block 22 is fixedly connected to the lifting adjustment frame 3 through a connecting block.
[0021] Working principle: First, connect the entire device to an external power supply, and then install the carrier plate 5 with an adapter groove 51 of the same size as the circuit board to be processed on the base 1. In this process, the connecting shaft 53 under the carrier plate 5 can be inserted into the square hole 62, and ensure that the bottom surface of the carrier plate 5 is against the ball 72 on the annular table 8. Then, the cylinder 73 is driven to push the flip plate 71 to rotate and rotate it to a horizontal state, so that the ball 72 at the bottom of the flip plate 71 is against the upper end of the carrier plate 5 to ensure the stability of the carrier plate 5. The output end of the stepper motor 6 is used to drive the connecting sleeve 61 to rotate, so as to drive the carrier plate 5 to rotate step by step.

The adapter slot 51 is used for positioning, which is simple and convenient to operate and improves the processing efficiency. Secondly, when processing circuit boards of different thicknesses and then needing to align the laser focal length, the rocker 23 can be used to drive the threaded rod 21 to rotate, thereby driving the lifting block 22 to rise and fall, and finally driving the lifting adjustment frame 3 and the laser printing head 4 to rise and fall. The operation is simple and convenient, which improves the overall practicality of the equipment.
