Abstract
Description
Technical Field
[0001] The utility model relates to the field of earphone manufacturing equipment, in particular to an automatic diaphragm mounting mechanism for earphones. Background Art
[0002] In headphone production, a diaphragm is typically placed at the sound outlet to achieve desired effects (such as dust and water resistance). However, in actual installation, the diaphragm is relatively small, approximately a 1.5mm diameter circular piece (especially for in-ear headphones). This results in poor manual installation precision and significant visual fatigue, resulting in low installation efficiency and a significant impact on production accuracy. This is especially true for headphones with unusual structures, which present significant installation challenges. Utility Model Content
[0003] The main purpose of the utility model is to propose an automatic diaphragm installation mechanism for headphones, aiming to design an automated diaphragm attachment mechanism, thereby achieving rapid installation of the diaphragm and effectively ensuring the installation efficiency of the diaphragm.
[0004] To achieve the above-mentioned purpose, the present invention provides an automatic diaphragm installation mechanism for earphones, comprising:
[0005] A base, wherein the base is provided with a first conveying device and a second conveying device, wherein the first conveying device is provided with a sheet seat and its relative position is adjusted, wherein the sheet seat is used to place the sheet, and the second conveying device is detachably mounted with an earphone fixture and is used to adjust its relative position;
[0006] A gantry frame is mounted on the base. The gantry frame is provided with a laterally movable sheet clamping device and a laterally movable film clamping device. The sheet clamping device is used to clamp sheets from the sheet stacking seat of the base to the sheet seat or to clamp waste sheets from the sheet seat to the unloading seat.
[0007] The diaphragm clamping device is used to clamp the diaphragm and install it on the sound outlet of the earphone.
[0008] In the actual design, the material sheet is provided with diaphragms arranged vertically and horizontally, wherein the diaphragms are provided with a glue layer at a position away from the upper wall. Therefore, when the earphone jig is placed with multiple shells, the second conveying device moves to the end, thereby placing the earphone jig on the second conveying device;
[0009] At the same time, the sheet clamping device clamps the sheet from the sheet stacking seat to the sheet seat and fixes it. Then the diaphragm clamping device can clamp the diaphragms in turn and install them on the sound outlet of the earphone (directly stick them). When the diaphragms on the sheet are clamped, they are clamped to the unloading seat by the sheet clamping device.
[0010] The installation of the earphone shell can be done by manual loading or by robotic loading;
[0011] It has a simple structure and stable operation. For products with smaller diameters, it can effectively improve the installation efficiency of the diaphragm and achieve higher accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figures 1 to 4 As shown, an automatic diaphragm installation mechanism for earphones, comprising:
[0022] The base 1 is provided with a first conveying device 11 and a second conveying device 12. The first conveying device 11 is provided with a sheet seat 101 and its relative position is adjusted. The sheet seat 101 is used to place the sheet. The second conveying device 12 is detachably mounted with an earphone fixture 5 and is used to adjust its relative position.
[0023] The gantry 4 is provided on the base 1 and is provided with a laterally movable sheet clamping device 2 and a laterally movable film clamping device 3. The sheet clamping device 2 is used to clamp sheets from the sheet stacking seat 102 of the base 1 to the sheet seat 101 or to clamp waste sheets from the sheet seat 101 to the unloading seat 103.
[0024] The diaphragm clamping device 3 is used to clamp the diaphragm and install it on the sound outlet 201 of the earphone.
[0025] In the actual design, the sheet is provided with diaphragms arranged vertically and horizontally, wherein the diaphragms are provided with a glue layer at a position away from the upper wall. Therefore, when the earphone jig 5 is placed with multiple shells, the second conveying device 12 moves to the end, thereby placing the earphone jig 5 on the second conveying device 12;
[0026] At the same time, the sheet clamping device 2 clamps the sheet from the sheet stacking seat to the sheet seat 101 and fixes it. Then the diaphragm clamping device 3 can clamp the diaphragms in turn and install them on the sound outlet 201 of the earphone (directly stick them). When the diaphragms on the sheet are clamped, they are clamped to the unloading seat 103 by the sheet clamping device 2.
[0027] The earphone housing 200 can be installed by manual loading or by a robot.
[0028] It has a simple structure and stable operation. For products with smaller diameters, it can effectively improve the installation efficiency of the diaphragm and achieve higher accuracy.
[0029] Specifically, the sheet clamping device 2 is arranged on the front wall of the gantry 4, and the film clamping device 3 is arranged on the rear wall of the gantry 4, thereby realizing the staggered movement of the sheet clamping device 2 and the film clamping device 3, making the mechanism more streamlined.
[0030] Furthermore, two second conveying devices 12 are provided and spaced apart on both sides of the first conveying device 11 , and correspondingly, two groups of film clamping devices 3 are provided, thereby effectively improving installation efficiency.
[0031] In the embodiment of the present utility model, the first conveying device 11 and the second conveying device 12 have the same structure, including a longitudinal guide rail arranged along the length direction of the base 1, a longitudinal slider slidably installed on the longitudinal guide rail, and a longitudinal screw pair for driving the longitudinal slider, wherein the material clamping device 2 and the membrane clamping device 3 are respectively moved laterally, and cooperate with each other through the longitudinal movement of the conveying device, thereby realizing the function of staggered clamping and staggered placement of the membrane, streamlining the mechanism coordination, of course, the existing three-axis movable frame structure can also be adopted, but this structure is more complicated.
[0032] Specifically, the sheet clamping device 2 includes a first lateral moving device 21, a first vertical moving device 22 provided on the first lateral moving device 21, and a first suction cup 23 provided on the first vertical moving device 22;

The earphone housing 200 is mounted on the positioning areas 51. Correspondingly, two second suction cups 33 are spaced apart and positioned opposite the positioning areas 51. That is, the spacing between the diaphragms is aligned with the two second suction cups 33, allowing for simultaneous gripping and installation of two diaphragms, further improving production efficiency.
[0035] Furthermore, the first lateral movement device 21 and the second lateral movement device 31 have the same structure, including a lateral guide rail provided on the gantry 4, a lateral slider slidably mounted on the lateral guide rail, and a lateral screw pair for driving the lateral slider. Of course, existing structures can also be used to achieve lateral movement, such as a telescopic device or a pulley.

Due to their small size and weight, they can be directly driven by a telescopic motor or a telescopic cylinder.
[0037] Specifically, the first suction cup 23 and the second suction cup 33 are vacuum suction cups.
[0038] In an embodiment of the present invention, the gantry 4 is arranged in the middle of the first conveying device 11, and the middle of the second conveying device extends from the gantry 4 toward both ends, thereby realizing loading of the earphone shell at both ends.
[0039] In this embodiment of the present invention, the sheet holder 101 is provided with a turning device 6, which is equipped with a positioning clamp 61 that can secure the end of the sheet. The gantry 4 is also provided with a visual inspection device 7. The visual inspection device 7 allows for rapid inspection of the attached film, wherein the positioning clamp 61 is used to secure the film, thereby preventing abnormal movement of the film clamping device 3 when clamping the film.
