This small but critical component plays multiple roles in earphone design and provides users with a series of important advantages. Its main functions are: 1. Dust and foreign matter protection; 2. Protection of internal components; 3. Regulating airflow; 4. Optimizing sound quality. At the same time, the mesh plays an indispensable role in improving the durability, comfort and sound quality of the earphone.
[0003] During the production process of earphones, the mesh is usually fitted and fixed in the inner cavity of the earphone. For the mesh of the front cavity tuning hole of the full-in-ear earphone, its position is mostly set on the inside of the sound outlet. At the current production stage, the assembly of the mesh of the front cavity tuning hole mainly relies on manual labor. Due to the small space inside the sound outlet, it is difficult for workers to press the mesh of the front cavity tuning hole with tweezers. The mesh does not fit well with the cavity, resulting in air leakage in the front cavity when the earphone is working, which greatly affects the sound quality of the product. In addition, the distance between the front cavity tuning hole and the speaker diaphragm is small, and the diaphragm is easily damaged by workers using tweezers.
[0004] In view of this, the inventor proposes the following technical solution. Utility model content:

[0013] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: in the utility model, by placing the product on the positioning seat, and pushing the positioning seat along the X-axis guide rail to the bottom of the pressure rod, when the sensor detects that the product is in place, it triggers the cylinder to push the moving seat down, and pushes the pressure rod into the product to press the mesh cloth, thereby achieving a close fit between the mesh cloth and the product, thereby replacing manual pressing of the mesh cloth, with high efficiency and effectively ensuring the yield of finished products. Description of the drawings:
[0014] Figure 1 This is a schematic diagram of the structure of the utility model Figure 1 ;
[0015] Figure 2 This is a schematic diagram of the structure of the utility model Figure 2 . Specific implementation method:
[0016] The utility model is further described below in conjunction with specific embodiments and drawings.
[0017] The product of the utility model is a semi-finished earphone. The device is a pneumatic front cavity tuning hole mesh fitting jig, which adopts a semi-automatic mechanical structure, guide rail sliding, and automatic sensing. When the jig senses that the earphone has reached a fixed position, the pressure rod moves downward along the guide rail to press the mesh of the front cavity tuning hole so that the mesh fits tightly with the cavity. The length of the pressure rod and the guide rail is fixed, and the speaker will not be damaged during the operation. Compared with manual work, this device has high efficiency and low cost.
[0018] See Figure 1 to Figure 2 As shown, a mesh laminating jig comprises: a machine 1, a supporting upright plate 2 arranged on the machine 1, a Z-axis guide rail 3 vertically arranged on the supporting upright plate 2, a moving seat 4 slidably mounted on the Z-axis guide rail 3, an X-axis guide rail 5 horizontally arranged on the machine 1 and perpendicular to the supporting upright plate 2, a positioning seat 6 slidably arranged on the X-axis guide rail 5 and used for positioning the product, a pressing rod 7 arranged on the moving seat 4 and moving up and down therewith to press the mesh in the inner cavity of the product, and a cylinder arranged in the machine 1 and used to drive the moving seat 4 to move up and down, and a sensor 8 for detecting the approach of the positioning seat 6 and triggering the operation of the cylinder is arranged on the supporting upright plate 2. By placing the product on the positioning seat 6 and pushing the positioning seat 6 along the X-axis guide rail 5 to the bottom of the pressure rod 7, when the sensor 8 detects that the product is in place, the cylinder is triggered to push the moving seat 4 down, and the pressure rod 7 is pushed into the product to press the mesh cloth, thereby achieving a close fit between the mesh cloth and the product, thereby replacing manual pressing of the mesh cloth, with high efficiency and effective guarantee of the yield rate.
[0019] The upper end surface of the positioning seat 6 is provided with a cavity 60 for positioning the product, and the pressure rod 7 is located above the cavity 60 and can be pressed down into the cavity 60 to fit the mesh cloth to the inner wall. The cavity 60 that is consistent with the contour of the product is provided in the positioning seat 6, so that after the product is placed in the cavity 60, the product can be accurately positioned.
[0020] The lower end of the positioning seat 6 is provided with a limit block 61 for stopping, and the machine table 1 is provided with a positioning block 11 for contacting with the limit block 61 to stop the positioning seat 6 from moving toward one end of the X-axis guide rail 5. The front end of the machine table 1 is also provided with a limit baffle 12 for stopping the positioning seat 6 from moving toward the other end of the X-axis guide rail 5. Among them, the limit block 61 is located at one side of the bottom of the positioning seat 6, the positioning block 11 is located beside the X-axis guide rail 5, and the limit baffle 12 protrudes from the upper end surface of the machine table 1 and extends to the front end of the positioning seat 6. By setting the positioning block 11 and the limit baffle 12 on the machine table 1 to limit the positioning seat 6, the positioning seat 6 is prevented from derailing from the X-axis guide rail 5, and the positioning block 11 can be used to achieve accurate positioning of the positioning seat 6, so that it is convenient to manually push the positioning seat 6 to accurately stay below the pressure rod 7.
[0021] The moving seat 4 includes a slider 41 installed on the Z-axis guide rail 3 and used to support the pressure rod 7, a side plate 42 arranged on one side of the slider 41 and extending to the rear of the supporting plate 2, and a force plate 43 arranged on the side plate 42 and used to contact the cylinder.
[0022] The piston of the cylinder is provided with a driving shaft 9 which passes through the machine 1 and extends through the force-bearing plate 43. The driving shaft 9 is sleeved with a spring 90 which presses against the force-bearing plate 43. The upper end of the driving shaft 9 is provided with a retaining ring 91 for limiting the spring 90, and the spring 90 is located between the retaining ring 91 and the force-bearing plate 43. By sleeved with the spring 90 on the driving shaft 9 and utilizing the spring 90 to be located above the force-bearing plate 43, when the cylinder pushes the moving seat 4 to descend, a force needs to be applied through the spring 90, thereby achieving flexible contact between the pressure rod 7 and the product, avoiding the pressure rod 7 from directly hitting the product and damaging the mesh, thereby improving the success rate of mesh fitting. Therefore, utilizing the floating contact of the spring 90, the mesh of the front cavity tuning hole can be tightly fitted without loss, thereby improving the product yield and functional stability.
[0023] To sum up, when the utility model is used, the product is manually placed in the cavity 60 of the positioning seat 6, and the positioning seat 6 is pushed to move along the X-axis guide rail 5 to the bottom of the pressure rod 7; further, when the sensor 8 detects that the positioning seat 6 is in place, the cylinder is triggered to push the moving seat 4 down, so that the pressure rod 7 enters the inner cavity of the product and presses the mesh cloth to the inner wall of the product; further, the cylinder pushes the moving seat to reset, and the pressure rod 7 is separated from the product, and then the positioning seat 6 is manually returned to the initial position, and the compressed product is taken out of the positioning seat 6, and the product to be compressed is placed in the cavity 60 of the positioning seat 6 to continue to compress and fit the mesh cloth.
[0024] This fixture is suitable for the mesh bonding of the front cavity tuning hole of headphones whose front cavity tuning hole is located inside the sound outlet. The mesh position and the distance between the pressure rod are fixed, and the size of the pressure rod matches the mesh. After the fixture senses that the semi-finished headphone has reached the fixed position, the pressure rod moves downward along the guide rail through pneumatic conduction to press the mesh, so that the mesh fits tightly with the cavity.
