Technical Field

[0001] The utility model belongs to the technical field of headphone production and processing, and specifically relates to a headphone processing and magnetizing device. Background Art

[0002] A headphone is a device that converts an audio signal into sound and transmits it to the user's ears. There are multiple types of headphones, and among them, wireless Bluetooth headphones are a common type in daily life.

[0003] A wireless Bluetooth headphone generally consists of a headphone case and a headphone. A storage battery is installed inside the headphone case for charging the headphone. At the same time, a magnetic suction type protective cover is provided on the headphone case on the market to facilitate the protection of the headphone when it is not in use.

[0004] Magnetizing generally refers to installing a magnet inside other objects. During the production process of headphones, it is necessary to magnetize the headphone case. A tiny magnet is placed into the installation groove on the headphone case in the corresponding direction, and then sealant treatment is carried out to complete the magnetizing.

[0005] During long-term observation of the existing headphone processing and magnetizing device, it is found that when the magnets are conveyed to the magnetizing device by the feeding device, multiple magnets will adsorb to each other. Since the magnets installed in the headphone case are small in volume, it is easy to pick up multiple magnets during operation, and the excess magnets need to be removed, which affects the magnetizing speed.

[0006] Therefore, the utility model provides a headphone processing and magnetizing device. Content of the Utility Model

[0009] Preferably, a sliding plate is slidably connected to the top of the equipment rack; a first electric cylinder is fixedly connected to the side wall of the equipment rack; the output end of the first electric cylinder is fixedly connected to the side wall of the sliding plate; a second electric cylinder is fixedly connected to the bottom of the sliding plate; the output end of the second electric cylinder is fixedly connected to a hollow fixing rod; a second magnet is slidably connected inside the hollow fixing rod; through the above structure, the magnet trapped inside the first groove can be conveniently taken out, and the magnet used as the magnetizing material can be accurately moved to the magnetizing position. At the same time, since the direction of the second magnet inside the hollow fixing rod remains unchanged, the magnetic field direction of the magnet used as the material remains consistent when it is moved to the magnetizing position.

[0010] Preferably, a second fixing rod is fixedly connected to the top of the fixing plate; a fixing column is fixedly connected to the side wall of the second fixing rod; the fixing column extends into the inside of the disc; through the above structure, the adsorption force of the first magnet on the magnet used as the magnetizing material inside the first groove can be reduced, so that it is more convenient for the second magnet to suck out the magnet used as the magnetizing material inside the first groove.

[0011] Preferably, a fixing ring is fixedly connected to the end of the fixing column; a pair of rotating columns are rotatably connected to the side wall of the fixing ring; through the above structure, the sliding friction on the surface of the hollow tube can be converted into rolling friction, thereby reducing the frictional damage between the hollow tube and the fixing column.

[0012] Preferably, a third electric cylinder is fixedly connected inside the hollow fixing rod; the output end of the third electric cylinder faces the second magnet, and the output end of the third electric cylinder is fixedly connected to the second magnet; through the above structure, after the magnet used as the magnetizing material is placed inside the installation groove on the earphone box, the situation where the magnet is attracted by the second magnet and leaves the inside of the installation groove can be reduced.

[0013] Preferably, a telescopic rod is fixedly connected to the side wall of the fixed block; the other end of the telescopic rod is fixedly connected to the hollow tube; the telescopic rod is located inside the spring; through the above structure, the situation where the squeezed hollow tube moves towards the direction of another hollow tube and collides with another hollow tube is reduced.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. For the earphone processing and magnetizing equipment of the present utility model, through the rotation of the disc, the magnet at the top of the feeding pipe is peeled off into the inside of the first groove, and the subsequent magnets will be blocked by the disc. The magnet falling into the first groove will be attracted to the first magnet inside the hollow tube, so that it will not fall off from the inside of the first groove. Through the above structure, a single magnet can be more accurately taken out from the pile of smaller magnets adsorbed together for subsequent magnetizing operations, improving the feeding speed of a single magnet, and thus improving the magnetizing speed.

[0016] 2. The magnetic punching device for earphone processing according to the utility model attracts the end of the hollow fixed rod close to the first groove through the operation of the second electric cylinder, so that the magnet in the first groove is attracted by the second magnet. Then, the second electric cylinder drives the hollow fixed rod away from the disc, sucks out the magnet in the first groove, and accurately moves the magnet as the magnetic punching material to the magnetic punching position. At the same time, since the direction of the second magnet in the hollow fixed rod remains unchanged, the magnetic field direction of the magnet as the material remains consistent when it moves to the magnetic punching position.

Detailed Embodiment

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Such as Figures 1 to 3As shown in the figure, a magnetic device for earphone processing according to an embodiment of the present utility model includes a device frame 1; a fixing plate 12 is fixedly connected to the top of the device frame 1; a servo motor 13 is fixedly connected to the side wall of the fixing plate 12; a fixing block 14 is fixedly connected to the middle of the output end of the servo motor 13; a disc 15 is fixedly connected to the side wall of the fixing block 14; a plurality of first grooves 16 are formed in the middle of the outer side of the disc 15; the depth of the first groove 16 is the same as the thickness of the magnet to be installed; a feeding pipe 17 is communicated with the top of the device frame 1; the end of the feeding pipe 17 is in contact with the outside of the disc 15, and the shape and size of the inner wall of the feeding pipe 17 are the same as those of the first groove 16; a plurality of springs 18 are fixedly connected to the side wall of the fixing block 14; the other end of the spring 18 is fixedly connected to a hollow pipe 19; a first magnet 110 is fixedly connected to the inside of the hollow pipe 19; during operation, the magnets to be installed on the earphone box are transported along the feeding pipe 17 towards the disc 15 through a feeding device, and a plurality of magnets will adsorb each other in the feeding pipe 17 to form a column. With the start of the servo motor 13, the disc 15 will rotate. When the first groove 16 rotates to the top of the feeding pipe 17, the magnet at the topmost position in the feeding pipe 17 will be pushed by the feeding device of the magnet and fall into the first groove 16. With the continuous rotation of the disc 15, the topmost magnet will be peeled off from the stacked magnet column by the disc 15, and the subsequent magnets will be blocked by the disc 15. The magnet falling into the first groove 16 will attract the first magnet 110 in the hollow pipe 19, so that it will not fall off from the first groove 16 and wait for subsequent installation. Through the above structure, when magnetizing the earphone, a single magnet can be accurately taken out from a pile of smaller magnets adsorbed together for subsequent magnetizing operation, the feeding speed of a single magnet can be improved, and thus the magnetizing speed can be improved.

[0025] As Figures 1 to 4As shown in the figure, a sliding plate 2 is slidably connected to the top of the equipment rack 1; a first electric cylinder 21 is fixedly connected to the side wall of the equipment rack 1; the output end of the first electric cylinder 21 is fixedly connected to the side wall of the sliding plate 2; a second electric cylinder 22 is fixedly connected to the bottom of the sliding plate 2; the output end of the second electric cylinder 22 is fixedly connected to a hollow fixing rod 23; a second magnet 24 is slidably connected inside the hollow fixing rod 23; during operation, after a single magnet is taken out from the inside of the feeding pipe 17, as the disk 15 continues to rotate, the first groove 16 containing the magnet is rotated to face the direction of the hollow fixing rod 23, and then the end of the hollow fixing rod 23 is brought close to the first groove 16 by the operation of the second electric cylinder 22, so that the magnet inside the first groove 16 is attracted by the second magnet 24. By adjustment, the attraction force of the second magnet 24 on the magnet inside the first groove 16 is made greater than the attraction force of the first magnet 110 on the magnet inside the first groove 16, so that the second magnet 24 can adsorb the magnet inside the first groove 16. Then, the second electric cylinder 22 drives the hollow fixing rod 23 to move away from the disk 15, sucking out the magnet inside the first groove 16. Then, by the operation of the first electric cylinder 21, the magnet used as the material is transferred to the installation groove on the earphone box. Through the above structure, the magnet trapped inside the first groove 16 can be conveniently taken out, and the magnet used as the magnetizing material can be accurately moved to the magnetizing position. At the same time, since the direction of the second magnet 24 inside the hollow fixing rod 23 remains unchanged, the magnetic field direction of the magnet used as the material remains consistent when it is moved to the magnetizing position.

[0026] As Figures 1 to 3 shown, a second fixing rod 3 is fixedly connected to the top of the fixing plate 12; a fixing column 31 is fixedly connected to the side wall of the second fixing rod 3; the fixing column 31 extends into the inside of the disk 15; during operation, when the first groove 16 containing the magnet rotates to the corresponding position, the hollow tube 19 where the first magnet 110 attracted to the magnet inside the first groove 16 is located will be blocked by the fixing column 31 and thus move in the direction of the fixing block 14, so that the adsorption force between the first magnet 110 and the magnet inside the first groove 16 decreases due to the increase in distance, thus facilitating the attraction of the magnet inside the first groove 16 by the second magnet 24. Through the above structure, the adsorption force of the first magnet 110 on the magnet used as the magnetizing material inside the first groove 16 can be reduced, making it more convenient for the second magnet 24 to suck out the magnet used as the magnetizing material inside the first groove 16.

[0027] As Figures 1 to 3As shown, a fixing ring 4 is fixedly connected to the end of the fixing column 31; a pair of rotating columns 41 are rotatably connected to the side wall of the fixing ring 4; during operation, when the fixing column 31 enters between the inner wall of the hollow tube 19 and the inner wall of the disc 15, the rotating column 41 will contact the surface of the hollow tube 19 instead of the fixing column 31 and generate rolling friction. Through the above structure, the sliding friction on the surface of the hollow tube 19 can be converted into rolling friction, thereby reducing the frictional damage between the hollow tube 19 and the fixing column 31.

[0028] As Figures 1 to 4 shown, a third electric cylinder 5 is fixedly connected inside the hollow fixing rod 23; the output end of the third electric cylinder 5 faces the second magnet 24, and the output end of the third electric cylinder 5 is fixedly connected to the second magnet 24; during operation, after the magnet as the magnetizing material at the bottom of the hollow fixing rod 23 is transferred to the installation groove on the earphone box by the movement of the hollow fixing rod 23, the second magnet 24 is moved away from the earphone box by the operation of the third electric cylinder 5, so that the attracting force of the magnet as the magnetizing material by the second magnet 24 decreases, and finally it falls into the installation groove on the earphone box. Through the above structure, after the magnet as the magnetizing material is placed in the installation groove on the earphone box, the situation that the magnet is attracted by the second magnet 24 and leaves the installation groove can be reduced.

[0029] As Figures 1 to 2 shown, a telescopic rod 6 is fixedly connected to the side wall of the fixed block 14; the other end of the telescopic rod 6 is fixedly connected to the hollow tube 19; the telescopic rod 6 is located inside the spring 18; during operation, when the hollow tube 19 is squeezed and moves, the existence of the telescopic rod 6 can make the hollow tube 19 only move in the direction of the fixed block 14, preventing the squeezed hollow tube 19 from moving in the direction of another hollow tube 19 and colliding with another hollow tube 19.

[0030] As Figure 1 shown, a positioning block 7 is fixedly connected to the top of the equipment rack 1; a positioning groove 71 is opened at the top of the positioning block 7; during operation, the earphone box to be magnetized is placed inside the positioning groove 71, thereby completing the positioning of the earphone box and enabling the hollow fixing rod 23 to accurately transfer the magnet as the material to the installation groove.

[0031] During operation, the magnets to be installed on the earphone case are transported along the feeding pipe 17 towards the direction of the disc 15 through the feeding device. Multiple magnets will adsorb to each other inside the feeding pipe 17 to form a column. With the start of the servo motor 13, the disc 15 will rotate. When the first groove 16 rotates to the top of the feeding pipe 17, the uppermost magnet inside the feeding pipe 17 will fall into the inside of the first groove 16 under the push of the magnet feeding device. With the continuous rotation of the disc 15, the topmost magnet will be peeled off from the stacked magnet column by the disc 15, and the subsequent magnets will be blocked by the disc 15. The magnet that has fallen into the inside of the first groove 16 will be attracted to the first magnet 110 inside the hollow pipe 19, so it will not fall off from the inside of the first groove 16 and waits for subsequent installation. After taking out a single magnet from inside the feeding pipe 17, with the continuous rotation of the disc 15, the first groove 16 containing the magnet is rotated to face the direction of the hollow fixed rod 23. Then, by operating the second electric cylinder 22, the end of the hollow fixed rod 23 is brought close to the first groove 16, so that the magnet inside the first groove 16 is attracted by the second magnet 24. By adjustment, the attraction force of the second magnet 24 on the magnet inside the first groove 16 is made greater than the attraction force of the first magnet 110 on the magnet inside the first groove 16, so that the second magnet 24 can adsorb the magnet inside the first groove 16. Then, the second electric cylinder 22 drives the hollow fixed rod 23 away from the disc 15 to suck out the magnet inside the first groove 16. By operating the first electric cylinder 21, the magnet as the material is transferred to the installation groove on the earphone case. When the first groove 16 containing the magnet rotates to the corresponding position, the hollow pipe 19 where the first magnet 110 attracting the magnet inside the first groove 16 is located will be blocked by the fixed column 31 and thus move towards the direction of the fixed block 14. As a result, the adsorption force between the first magnet 110 and the magnet inside the first groove 16 decreases due to the increase in distance, which facilitates the attraction of the magnet inside the first groove 16 by the second magnet 24. When the fixed column 31 enters between the hollow pipe 19 and the inner wall of the disc 15, the rotating column 41 will contact the surface of the hollow pipe 19 instead of the fixed column 31 and generate rolling friction. After transferring the magnet as the magnetizing material located at the bottom of the hollow fixed rod 23 to the installation groove inside the earphone case by moving the hollow fixed rod 23, by operating the third electric cylinder 5, the second magnet 24 is moved away from the earphone case, so that the attraction force on the magnet as the magnetizing material by the second magnet 24 decreases, and finally it falls into the installation groove inside the earphone case. When the hollow pipe 19 is squeezed and moves, the existence of the telescopic rod 6 enables the hollow pipe 19 to only move towards the direction of the fixed block 14, preventing the squeezed hollow pipe 19 from moving towards the direction of another hollow pipe 19 and colliding with another hollow pipe 19.
