[0019] like Figure 1-5 As shown, the embodiments of this utility model include:

[0020] A four-axis vision-based intelligent cabinet-type screw fastening machine includes a cabinet 1, a screw feeder 2, a Y-axis servo screw linear module slide 3, an XZ-axis two-axis servo screw linear module slide 4, an electric screwdriver head 5, a fourth longitudinal axis rail 6, a lifting arm 7, and a suction nozzle 8. The screw feeder 2 is mounted on the cabinet 1, and the Y-axis servo screw linear module slides 3 are symmetrically arranged on both sides of the screw feeder 2. The cabinet 1 is equipped with an XZ two-axis servo screw linear module slide 4. The XZ two-axis servo screw linear module slide 4 is equipped with a gantry bracket 9 and a screwdriver head 5 is suspended on it. The XZ two-axis servo screw linear module slide 4 is also equipped with a fourth longitudinal axis rail 6 and a lifting arm 7 is attached thereon. The lifting arm 7 passes through the gantry bracket 9 and suspends the suction nozzle 8 of the coaxially matched screwdriver head 5. The screwdriver head 5 is externally mounted with a vision camera 10 and a linear displacement sensor 11 on both sides. The lifting arm 7 is horizontally connected to a sensing plate 12 facing the linear displacement sensor 11.

[0021] The suction nozzle 8 is connected to the negative pressure gauge 13, the screw feeder 2 has a defective material box 14 hanging on its side, the XZ two-axis servo lead screw linear module slide 4 and the negative pressure gauge 13 are electrically connected to an industrial control computer, and the industrial control computer is placed in the cabinet 1.

[0025] Furthermore, a plurality of air passage grooves 21 are provided at the port of the suction nozzle 8.

[0026] Workpieces of different specifications can share a single device to automate the fastening of screws of the same specification. This is achieved through automatic addressing and positioning via a vision camera 10. When the target is at different horizontal heights, a linear displacement sensor 11 can be used to precisely detect the height of the suction nozzle 8, thereby making high-precision adaptive adjustments to the downward height of the electric screwdriver head 5 and accurately determining whether the screw is properly fastened. This significantly improves the intelligence of screw fastening, enhances reliability, and increases production efficiency, allowing for rapid production without additional programming. Furthermore, the air passage 21 enhances the stability of the screwdriver bit during fastening, preventing screws from suddenly falling off. In addition, a negative pressure gauge 13 installed in the air path of the suction nozzle 8 monitors the adsorption pressure in real time, judging defective screws based on negative pressure deviation thresholds and promptly discarding defective materials.
