[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] refer to Figure 1-4 A detection base 1 is set, and a magnetic detection process is carried out on the detection base 1. A magnetic detection device 2 and a rotating placement device 3 are respectively set on the detection base 1, wherein the magnetic detection device 2 can perform magnetic detection on multiple points of the earphone component, and the rotating placement device 3 can fix the earphone component and flip it, and cooperate with the magnetic detection device 2 to perform multi-point detection.

[0026] refer to Figure 1-4 The rotating placement device 3 includes a rotating rotating placement plate 31, an earphone placement slot 311 is opened on the rotating placement plate 31, and several horizontal positioning springs 32 are arranged in an array on the side wall of the earphone placement slot 311. A horizontal positioning rod 321 is slidingly arranged inside the horizontal positioning spring 32, and the end of the horizontal positioning rod 321 is fixedly connected to a pull rod 322. By pulling the pull rod 322, the horizontal positioning spring 32 can be stretched, and the horizontal positioning spring 32 will produce a rebound effect. The horizontal positioning spring 32 applies an elastic force toward the earphone placement slot 311 on the horizontal positioning rod 321, and the horizontal positioning rod 321 extends into the earphone placement slot 311 and is slidably connected. The end of the horizontal positioning rod 321 is fixedly connected to a horizontal pressing block 33. When the earphone is inserted, it will contact the bottom of the earphone through the interference of the horizontal pressing block 33 under the elastic force of the horizontal positioning spring 32, and fix the earphone in a horizontal position.

[0027] refer to Figure 1-4The inner wall of the earphone placement slot 311 is provided with an inner slide groove 312, and two symmetrically arranged vertical limit blocks 313 are slidably connected in the inner slide groove 312. The two vertical limit blocks 313 are connected by a vertical positioning spring 314 and exert elastic force toward each other. The two vertical limit blocks 313 are pulled and moved toward each other by two numerical positioning springs. A buffer 315 is fixedly connected to the middle of the inner slide groove 312. The buffer 315 can buffer the elastic force when the two vertical limit blocks 313 collide with each other. One end of the two vertical positioning springs 314 is fixedly connected to the buffer 315 relative to each other. On the two surfaces, the vertical limit block 313 includes a vertical extension rod 316, and the end of the vertical extension rod 316 is provided with a vertical guide surface 317, which can ensure that the earphones hit the vertical guide surface 317 when they are lowered. The two vertical limit blocks 313 are moved apart. When the earphones are inserted into the earphone placement slot 311, the two vertical limit blocks 313 will hit each other under the action of the vertical positioning spring 314 and hit the upper part of the earphones, forming a vertical limiting effect. An earphone giving groove 37 is provided on the outer side of the rotating placement plate 31, which can limit the special-shaped structure of the earphone head.

[0028] refer to Figure 1-4 The magnetic detection device 2 includes two symmetrically arranged detection linear modules 21 and a detection mechanism 22 slidingly arranged between the two detection linear modules 21. The detection linear module 21 can drive the detection mechanism 22 to move. The detection mechanism 22 includes a Hall sensor 221. The Hall sensor 221 can detect the magnetism of the earphone. The Hall sensor 221 can detect the change in the magnetic field strength of the magnetism, thereby transmitting different electrical signals to test the strength of the magnetic field. The Hall sensor 221 rotates toward the surface of the earphone placement slot 311. The magnetic detection device 2 also includes a detection connecting plate 23 connected between the two detection linear modules 21. The detection connecting plate 23 is fixedly connected There is a detection propulsion cylinder 231, the end of the detection propulsion cylinder 231 is fixedly connected to a detection driving member 232, the back of the detection connecting plate 23 is fixedly connected to a steering plate 24, the steering plate 24 is rotatably connected to a detection shaft 241, the Hall sensor 221 and the detection shaft 241 are fixedly connected, a linkage rod 242 is rotatably connected between the detection driving member 232 and the detection shaft 241, a detection slot 243 is provided on the linkage rod, the detection shaft 241 is slidably connected in the detection slot 243, which can ensure that when the piston rod of the detection propulsion cylinder 231 is extended, it can drive the Hall sensor 221 to rotate, and rotate toward the direction of the earphone and between different points for detection.

[0029] refer to Figure 1-4The rotating placement device 3 also includes a rotating base 34, which is provided with a rotating groove 35 for the rotating placement plate 31 to be rotatably connected. A rotating shaft is rotatably connected in the rotating groove 35, and the rotating placement plate 31 is fixedly connected to the rotating shaft. A rotating motor 36 is fixedly provided on one side of the rotating base 34, and the output end of the rotating motor 36 is fixedly connected to the rotating shaft. The rotating placement plate 31 is driven to rotate by the rotating motor 36, so that the earphones fixed thereon can be flipped, and then the magnetic detection on the back is performed by detecting the linear module 21.

[0030] The working principle of this mechanism is as follows: when performing magnetic detection, the earphone is placed in the earphone placement slot 311, the bottom of the earphone will conflict with the two vertical guide surfaces 317 and drive the two vertical limit blocks 313 to move to both sides. At this time, the pull rod 322 is pulled, and the pull rod 322 will bring the horizontal pressure block 33 to make way for an opening in the earphone placement slot 311. When the bottom of the earphone is inserted into the opening and the earphone as a whole cannot be inserted further, the special-shaped structure of the earphone head will conflict with the bottom of the earphone clearance slot 37. Release the pull rod 322, and the horizontal pressure block 33 will clamp the bottom of the earphone at the bottom. At this time, the head of the earphone is on the outside of the earphone placement slot 311, and the two vertical limit blocks 313 will move against each other under the tension of the vertical positioning spring 314. The magnetic field strength of the head of the headset is detected by the piston rod 231, and the magnetic field strength of the head of the headset is detected by the piston rod 231. When the head of the headset is detected, the rotating motor 36 is started, the rotating placement plate 31 is rotated and the bottom of the headset is facing upward. The detection linear module 21 is started to drive the magnetic detection device 2 to move to the rotated headset, and the magnetic strength of the bottom of the headset is detected again, thereby completing the multi-point detection process of the headset.

[0031] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be understood to be within the scope of protection of the present invention.
