[0002] A headphone is a type of earphone worn on the head, usually consisting of two parts, a signal transmitter and an earphone with a signal receiving and amplifying device. Different from traditional in-ear earphones, headphone is not inserted into the ear canal. The advantage of the headphone is that it causes less harm to the ears, while the disadvantage is that external sounds can be heard a little more clearly and the sound insulation effect is poor. Some headphones have a noise reduction function, which can reduce external noise and improve the sound quality and listening effect.

When performing laser engraving, there is a situation where QR codes need to be laser engraved on the side walls of both ear cups of the earphone. In the prior art, the laser engraving of the two QR codes needs to be carried out separately. After one side is laser engraved, the earphone is flipped and then the other side wall of the earphone is laser engraved. This method is likely to result in low processing efficiency of the earphone and asymmetry of the QR codes on both sides of the earphone, affecting the aesthetics of the earphone.

[0022] Specific embodiments are given below.

[0023] Such as Figures 1 to 2As shown in the figure, a QR code laser engraving device for an earphone housing according to an embodiment of the present utility model includes a processing body 1; a threaded rod 2 is rotatably connected inside the processing body 1; an adjusting block 3 is slidably connected inside the processing body 1; the threaded rod 2 is threadedly connected to the adjusting block 3; two fixing frames 4 are fixedly connected to the side wall of the adjusting block 3, and the two fixing frames 4 are symmetrically arranged; a support arm 5 is fixedly connected to the top of the processing body 1; two sliding grooves 6 are fixedly connected to the side wall of the support arm 5, and the two sliding grooves 6 are respectively arranged at the positions corresponding to the top and bottom of the corresponding fixing frame 4; a sliding block 7 is slidably connected inside the sliding groove 6; a laser engraving head 8 is slidably connected to the sliding block 7; the fixing frame 4 and the laser engraving head 8 are correspondingly arranged; during operation, when it is necessary to laser engrave a QR code on the side wall of the earphone, the ear cup of the earphone can be placed on the fixing frame 4, and the ear cup is fixed by the fixing frame 4. Then, the threaded rod 2 can be driven to rotate by a motor, and through the threaded cooperation between the threaded rod 2 and the adjusting block 3, the adjusting block 3 is driven to slide inside the processing body 1, so that the fixing frame 4 moves to the middle position of the corresponding sliding groove 6, and through the sliding of the sliding block 7 and the laser engraving head 8, the QR code on the earphone housing is laser engraved. At the same time, by controlling the switches of the laser engraving heads 8 at the top and bottom of the fixing frame 4, a single or two QR codes on the earphone housing can be laser engraved simultaneously, making the laser engraving process of the QR code on the earphone housing more convenient.

[0024] As Figures 2 to 3 shown, a sliding frame 9 is fixedly connected to the side wall of the adjusting block 3; a pulling arm 10 is slidably connected inside the sliding frame 9; a spring is fixedly connected between the pulling arm 10 and the side wall of the sliding frame 9; a fixing groove is formed at the end of the pulling arm 10; a fixing rod 11 is slidably connected inside the pulling arm 10; a spring is fixedly connected between the fixing rod 11 and the side wall of the pulling arm 10; the fixing rod 11 is arranged at the position corresponding to the fixing groove; the sliding frame 9 is arranged at the middle position between the corresponding two fixing frames 4; during operation, when the ear cup of the earphone is fixed by the fixing frame 4, the pulling arm 10 can be pulled, and the head beam of the earphone is placed inside the fixing groove. Then, the fixing rod 11 is pushed by the spring to fix the head beam of the earphone, so that when laser engraving the earphone housing, the relative position between the earphone housing and the laser engraving head 8 is easier to determine, and the laser engraving position of the QR code can be more accurate. At the same time, by fixing the head beam of the earphone through the fixing groove, the earphone can be better stabilized during laser engraving.

[0025] As Figures 1 to 2As shown, a plurality of guide rods 12 are fixedly connected inside the processing body 1; the guide rods 12 are arranged parallel to the threaded rod 2; the adjusting block 3 is slidably connected to the guide rods 12; during operation, when the adjusting block 3 is driven by the threaded rod 2 and slides inside the processing body 1, through the restriction of the guide rods 12 on the adjusting block 3, the situation of the adjusting block 3 tilting less during sliding can be made, and the sliding of the adjusting block 3 can be made more stable.

[0026] As Figure 3 shown, a rubber pad 13 is fixedly connected inside the fixing frame 4; the rubber pad 13 is arranged at a position of the fixing frame 4 away from the fixing rod 11; during operation, when the pulling arm 10 pulls and is fixed inside the fixing frame 4, by arranging the rubber pad 13 inside the fixing frame 4, the ear cups of the headphones can be protected, effectively avoiding the situation of wear between the ear cups and the fixing frame 4.

[0027] As Figures 2 to 4 shown, a positioning rod 14 is fixedly connected to the end of the threaded rod 2; the positioning rod 14 is rotatably connected at a position inside the processing body 1; during operation, when the threaded rod 2 rotates inside the processing body 1, by restricting the positioning rod 14 by the processing body 1, the situation of the threaded rod 2 tilting can be effectively avoided, so that the threaded rod 2 can be more stable during rotation.

[0028] As Figures 2 to 4 shown, a plurality of balls 15 are arranged between the processing body 1 and the positioning rod 14; the side walls of the balls 15 are in contact with the side walls of the processing body 1 and the positioning rod 14; during operation, when the threaded rod 2 rotates inside the positioning rod 14, by arranging the balls 15 between the processing body 1 and the positioning rod 14, the sliding friction between the processing body 1 and the positioning rod 14 can be changed into rolling friction, so that the friction force between the processing body 1 and the positioning rod 14 is smaller and the wear between the processing body 1 and the positioning rod 14 is less.

[0029] During operation, when it is necessary to laser engrave a two-dimensional code on the side wall of the headphone, the ear cup of the headphone can be placed on the fixing frame 4, and the ear cup is fixed by the fixing frame 4. Then, the threaded rod 2 can be driven to rotate by the motor, and through the threaded fit between the threaded rod 2 and the adjusting block 3, the adjusting block 3 is driven to slide inside the processing body 1, so that the fixing frame 4 is moved to a position corresponding to the middle of the sliding groove 6, and through the sliding of the sliding block 7 and the laser engraving head 8, the two-dimensional code on the headphone shell is laser engraved. At the same time, by controlling the switches of the laser engraving heads 8 at the top and bottom of the fixing frame 4, a single or two two-dimensional codes on the headphone shell can be laser engraved simultaneously, making the laser engraving process of the two-dimensional code on the headphone shell more convenient.

[0030] When the ear cups of the earphone are fixed by the fixing frame 4, the pulling arm 10 can be pulled to place the head beam of the earphone inside the fixing groove. Then, the fixing rod 11 is pushed by the spring to fix the head beam of the earphone, so that when the outer shell of the earphone is laser-engraved, the relative position between the outer shell of the earphone and the laser-engraving head 8 is easier to determine, and the laser-engraving position of the two-dimensional code can be made more accurate. At the same time, by fixing the head beam of the earphone through the fixing groove, the earphone can be better stabilized when being laser-engraved.

[0031] When the adjusting block 3 is driven by the threaded rod 2 and slides inside the processing body 1, the guiding rod 12 restricts the adjusting block 3, so that the adjusting block 3 is less likely to tilt during the sliding process, and the sliding of the adjusting block 3 is more stable.

[0032] When the pulling arm 10 is pulled and fixed inside the fixing frame 4, by providing a rubber pad 13 inside the fixing frame 4, the ear cups of the earphone can be protected, effectively avoiding wear between the ear cups and the fixing frame 4.

[0033] When the threaded rod 2 rotates inside the processing body 1, the processing body 1 restricts the positioning rod 14, effectively preventing the threaded rod 2 from tilting, so that the threaded rod 2 is more stable during the rotation process.

[0034] When the threaded rod 2 rotates inside the positioning rod 14, by providing a ball 15 between the processing body 1 and the positioning rod 14, the sliding friction between the processing body 1 and the positioning rod 14 can be changed into rolling friction, so that the friction between the processing body 1 and the positioning rod 14 is smaller, and the wear between the processing body 1 and the positioning rod 14 is less.
