Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the bidirectional positioning device for unmanned vehicles includes a frame 1, of which there are two frames 1, which are designed to be parallel on the left and right sides. A slide seat 2 is slidably connected to the top of the frame 1. A rotating rod 3 is rotatably connected to the top of the frame 1, and the rotating rod 3 is threaded through the slide seat 2. A first motor 4 is fixedly installed on the top of the left frame 1, and the first motor 4 is fixedly connected to the rotating rod 3 on the left side. A slide frame 5 is slidably connected inside the slide seat 2. A sprocket 6 is fixedly sleeved on the front end of the rotating rod 3, and a chain 7 is tightly fitted on the outside of the sprocket 6. A monitoring component 8 is installed on the outside of the frame 1. The monitoring component 8 includes a first mounting strip 801 fixed on the outside of the left frame 1. Several metal sensors 802 are fixed on the outside of the first mounting strip 801 from front to back. An iron plate 803 is fixed on the left side of the slide seat 2.

[0027] A hoist 9 is fixed inside the slide 5. The output end of the hoist 9 rotates through the slide 5. A steel cable 10 fixed outside the hoist 9 passes through the slide 5. A second motor 11 is fixed on the top right side of the slide 2. A connecting rod 12 fixed on the left side of the second motor 11 is rotatably connected to the slide 2. The connecting rod 12 is threaded through the slide 5. A second mounting strip 13 is fixed inside the left side of the frame 1. Several distance sensors 14 are fixed inside the second mounting strip 13 from front to back. A mounting plate 15 is fixed at the bottom of the steel cable 10. A detachable connecting rod is fixed at the bottom of the mounting plate 15. The plate 16 has an electromagnetic chuck 17 fixed at the four corners of its bottom. The mounting plate 15 has a limiting rod 18 fixed at both ends of its left side, and the limiting rod 18 slides through the slide 5. The mounting plate 15 has a vision sensor 19 fixed in the middle. The connecting plate 16 has a clearance hole 20 integrally formed in the middle. The right side of the frame 1 has a PLC control system 21 installed on its exterior. The PLC control system 21 is connected to the first motor 4, the second motor 11, the metal sensor 802, the distance sensor 14, the vision sensor 19, and the electromagnetic chuck 17 via wires.

[0028] First, by configuring the PLC control system 21, the metal sensor 802 and distance sensor 14, which are to be used separately, are activated. The first motor 4 drives the rotating rod 3 to rotate the sprocket 6 and chain 7. Through the threaded transmission design between the rotating rod 3 and the slide 2, the slide 2 drives the electromagnetic chuck 17 to move along the front and back direction of the frame 1 until the activated metal sensor 802 detects the iron piece 803. At this point, the first motor 4 stops running, and the second motor 11 starts. The second motor 11 drives the connecting rod 12 to rotate. Through the threaded transmission design between the connecting rod 12 and the slide 5... This causes the slide 5 to move left and right along the slide block 2 until the distance traveled reaches the value set by the activated distance sensor 14. At this point, the second motor 11 stops running, and the lifting device 9 is activated. The lifting device 9 controls the steel cable 10 to bring the electromagnetic chuck 17 into contact with the material. Once the electromagnetic chuck 17 reaches the value set by the vision sensor 19, it performs electromagnetic adsorption to grasp the material. Then, through the settings of the PLC control system 21, the lifting device 9, the second motor 11, and the first motor 4 are reset in sequence, thereby moving the material to the starting area. The limit rod 18 ensures the stability of the steel cable 10 when it drives the mounting plate 15, the linkage connecting plate 16, and the electromagnetic chuck 17 to rise and fall. Example 2

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a first placement plate 22 is fixed to the outer wall of the left scaffold 1, a second placement plate 23 is fixed to the inner wall of the left scaffold 1, a cavity 24 is integrally formed at the front end of the left scaffold 1, a Y-shaped tube 25 is fixedly formed inside the left scaffold 1, the Y-shaped tube 25 is fixedly passed through the first placement plate 22 and the second placement plate 23 on the left, a number of exhaust holes 26 are integrally formed at the bottom of the first placement plate 22 and the second placement plate 23 on the left, an installation hole 27 is integrally formed inside the left scaffold 1, an air pump 28 is fixedly formed outside the left scaffold 1, a cover 29 is fitted outside the air pump 28 and is fixedly connected to the scaffold 1, the air pump 28 is connected to the PLC control system 21 through a wire, a baffle 30 is fixedly formed on the left side inside the cover 29, the inside of the Y-shaped tube 25 is connected to the inside of the cavity 24, and the inside of the cavity 24 is connected to the inside of the installation hole 27.

[0030] According to the operation method in Embodiment 1, the PLC control system 21 controls the air pump 28 to start. The air pump 28 discharges external gas through the mounting hole 27, through the cavity 24, and then through the Y-shaped tube 25 into the first placement plate 22 and the second placement plate 23. The gas inside the first placement plate 22 and the second placement plate 23 is then discharged through the exhaust hole 26 to the monitoring end of the metal sensor 802 and the distance sensor 14, thereby removing the dust adhering to the monitoring end of the metal sensor 802 and the distance sensor 14, ensuring the accuracy of the metal sensor 802 and the distance sensor 14 during use. The baffle 30 can prevent external dust from entering the air pump 28.
