[0015] Preferably, the visual positioning system includes a mounting frame, the upper surface of the mounting frame is arranged on the outer wall of the fixing frame, and a camera is installed on the outer wall of the mounting frame.

[0016] Working principle: After the equipment is started, the workpiece is first fixed by the clamping assembly. The vacuum pump extracts the air between the fixture and the workpiece, and the workpiece is flatly adsorbed on the fixture surface to ensure that the workpiece is stable and does not move during the processing; The CNC system is based on a multi-axis linkage controller. After receiving the preset cutting program, it synchronously controls the three-axis motion of the motion platform mechanism: Motor 1 drives ball screw 1 through a synchronous belt, driving slide frame 1 to slide the laser cutter back and forth; Motor 2 drives ball screw 2, causing slide frame 2 to slide left and right; Motor 3 drives ball screw 3, which adjusts the vertical height of the cutting head through slide frame 3. The three systems work together to achieve precise positioning of the cutting head in three-dimensional space. The visual positioning system uses dual cameras on the mounting frame to capture the workpiece position and surface features in real time. After image algorithm processing, the deviation data is fed back to the CNC system, which dynamically corrects the motion platform trajectory to ensure that the cutting path accurately matches the actual position of the workpiece, eliminating manual positioning errors. During cutting, the electric push rod extends and pushes the bracket, driving slider 1 along the slide rail via the slide rod. Simultaneously, the rotating plate retracts into the protective housing under the limit of slider 2, exposing the cutting head. At this time, the limit block at the top of the slide rod rises into the adjustment housing, unblocking the delivery pipe. The circulating pump in the water tank drives the coolant through the cooling sleeve around the laser cutter, absorbing the heat generated by the cutting head during operation. After absorbing the heat, the coolant flows back to the water tank to dissipate the heat, forming a closed-loop cooling system. After the operation is completed, the electric push rod retracts in the opposite direction, the rotating plate closes the protective shell, the limit block descends to block the delivery pipe, and the coolant flow is automatically cut off to avoid energy loss in the non-working state.

[0017] The present invention provides a high-precision CNC automated laser cutting machine. It has the following beneficial effects: 1. The present invention protects the laser cutter through the cooperation of the protective shell, the electric push rod, the bracket, the slide rod, the slider 1, the slide rail, the rotating plate and the slider 2, thereby preventing the cutting head from being damaged by external collisions, dust pollution and the like when it is idle or not cutting.

[0018] 2. The present invention realizes the recycling of coolant and cools the laser cutter through the water tank, circulation pump, delivery pipe and cooling sleeve; further, through the limiting block, sliding rod and adjusting shell, the circulation of coolant is automatically controlled according to the working state of the laser cutter, thereby improving the degree of automation of the equipment, saving energy and reducing coolant loss and pollution.

[0019] 3. The present invention realizes the control of the motion platform structure and the three-axis linkage motion of the laser cutter through the cooperation of motor 1, synchronous belt, ball screw 1, slide frame 1, motor 2, ball screw 2, slide frame 2, motor 3, ball screw 3, slide frame 3 and CNC system, thereby realizing high-precision and high-efficiency laser cutting.

[0025] Specifically, the base 1 fixes the fixed frame 2, the fixed frame 2 supports the motion platform structure 3, and the motion platform structure 3 is used to push the laser cutter 4 to move. The laser cutter 4 consists of a laser generator and a cutting head. The laser generator adopts a fiber laser with a power of 2000W. The focusing mirror of the cutting head is made of coated quartz material, and the nozzle is made of copper alloy. The protective shell 5 is set at the cutting head position. The protective shell 5 is generally made of metal material with a certain thickness and strength.

Two groups of circulation pumps 14 are arranged inside the water tank 13, which are used to output and input coolant respectively. The circulation pump 14 transports and recovers coolant to the cooling sleeve 16 through the delivery pipe 15.

At this time, the limiting block 17 slides into the interior of the adjusting shell 18, and the delivery pipe 15 circulates normally. When the rotating plate 11 is closed, the limiting block 17 descends to block the delivery pipe 15, and automatically controls the circulation of the coolant according to the working status of the laser cutter 4, which not only improves the degree of automation of the equipment, but also avoids unnecessary circulation of the coolant when the laser cutter 4 is not working, saves energy, and reduces the loss and pollution of the coolant.

The outer wall of the ball screw 3 27 is rotatably connected to the outer wall of the sliding frame 25. The outer wall of the ball screw 3 27 is threadedly connected to the sliding frame 3 28. The outer wall of the sliding frame 3 28 is fixedly connected to the outer walls of the laser cutter 4 and the water tank 13.
