[0002] The headphone mesh refers to the mesh-like fabric covering the sound hole of the headphone. It is mainly used to protect the speaker, sound filtering, etc. The mesh can protect the speaker unit inside the headphone from dust and impurities, and the mesh can filter the sound to a certain extent, reduce high-frequency noise, and make the sound softer. For in-ear headphones, due to their small size, the size of the mesh is generally slightly larger than the sound hole, and there is generally a recessed position designed inside for the mesh to be installed, so it cannot be directly installed flat. In order to adapt to the automated installation of the mesh, the installation position is generally set between the two buckled headphone shells, but this also limits the design of the headphone.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 4As shown, an embodiment of the present invention provides an automatic assembly device for earphone mesh, including a machine body 1, on which a loading component 2, a transfer platform 3, an assembly robot 4 and an assembly component 5 are provided; the loading component 2 is used to transfer the mesh 91 to the transfer platform 3; the transfer platform 3 is used to transfer the mesh 91 to a position close to the assembly component 5; the assembly component 5 includes a carrier plate 51 for mounting an earphone housing 90 and a rotating mechanism 52 for driving the carrier plate 51 to rotate from horizontal to inclined; the assembly robot 4 is used to take out the mesh 91 on the transfer platform 3 and rotate it to an angle where the mesh 91 is perpendicular to the carrier plate 51, and then put the mesh 91 into the installation position 901 of the earphone housing 90. The loading component takes out a single mesh and places the mesh on the transfer platform. After the mesh is taken out by the assembly robot, it is placed on the carrier plate for installation to complete the automatic assembly. In addition, this solution is suitable for installation in a recessed position within a single-sided shell, which cannot be placed directly. After the carrier is rotated from a horizontal state to an inclined state by assembling the components, and then the assembly robot rotates it to a certain tilt angle, the grid is placed in to complete the assembly.

[0019] This solution makes it easier for the mesh to enter the earphone housing and fall into the recessed installation position by rotating the carrier plate to an inclined state. Correspondingly, rotating to an inclined state also prevents the earphone housing 90 from being detached or shifted from the carrier plate 51 due to excessive rotation, thereby affecting the accuracy of the subsequent automated action of placing the mesh.

[0020] Similarly, after the earphone shell 90 rotates and tilts along with the carrier plate 51, the open end of the earphone shell 90 is tilted and faces the direction of the assembly robot 4. In order to facilitate the removal of the mesh cloth 91, the assembly robot 4 similarly first takes out the mesh cloth 91 in the horizontal direction, and before installation, it is first rotated to tilt the horizontal mesh cloth 91 to a direction perpendicular to the carrier plate 51. At this time, the mesh cloth 91 is then translated and sent into the earphone shell 90. Since the mesh cloth 91 is perpendicular to the direction of the earphone shell 90, it is equivalent to maintaining a posture horizontal to the installation position and entering the upper side of the installation position. Therefore, after the mesh cloth 91 enters the earphone shell 90, it can be opposite to the installation position. At this time, it only needs to be moved in the opposite straight line of the inclination of the earphone shell 90 to place the mesh cloth 91 into the recessed installation position.

[0021] Specifically, in this solution, the assembly component 5 also includes a lifting mechanism 53, which is connected to the rotating mechanism 52 and is used to lift and lower the carrier plate 51. After the carrier plate 51 is placed on the rotating mechanism 52, it is first lifted by the lifting mechanism 53 and then rotated to be opposite to the assembly robot 4 to install the mesh.

[0022] In the embodiment of the present invention, the body 1 is also provided with a detection component 80 on the upper side of the assembly component 5. The detection component 80 is a detection camera. After the carrier plate 51 is lifted by the lifting mechanism 53, it is close to the detection camera. The detection camera is used to confirm whether the earphone shell 90 is installed at multiple positions on the carrier plate 51, so as to facilitate the subsequent installation of the mesh cloth 91 to ensure that it can be installed in the earphone shell 90.

[0023] Specifically, Figures 7 to 10 As shown, in this solution, the rotating mechanism 52 includes a rotating frame 521 and a rotating motor 522, and the rotating motor 522 is arranged on the lifting mechanism 53. The assembly component 5 also includes a limiting frame 54, and a positioning protrusion 5211 is arranged on one side of the rotating frame 521. When the rotating frame 521 is at the lowest position, the positioning protrusion 5211 is inserted into the limiting frame 54. Moreover, in this solution, a concave position for the positioning protrusion 5211 to be inserted is provided at the upper end of the limiting frame 54, and rollers or arc-shaped guide structures are arranged on both sides of the concave position, so that the positioning protrusion 5211 is adjusted by the rollers or arc-shaped guide structures on both sides during the insertion process of the concave position to keep the carrier 51 on the rotating frame 521 returned to the horizontal plane, which is convenient for subsequent positioning.

[0024] In addition, in this solution, a plurality of lifting mechanisms 53 are provided on the machine body 1. After the carrier plate 51 is loaded with the assembly components 5, it is transferred to the next lifting mechanism 53 for the next step of compaction or unloading.

[0025] like Figure 5 As shown, in the embodiment of the present invention, the specific structure of the feeding assembly 2 is as follows: the feeding assembly 2 includes a feeding adsorption member 21, a material bin 22, a feeding rack 23 and a transport member 24; the material bin 22 is used to store the mesh cloth plate 92; the transport member 24 is used to transport the mesh cloth plate 92 at the material bin 22 to the feeding rack 23; the feeding adsorption member 21 is used to absorb and transfer a single mesh cloth 91 on the mesh cloth plate 92 on the feeding rack 23 to the transfer platform 3. Generally speaking, a plurality of mesh cloths 91 are attached to the mesh cloth plate 92. In this solution, the mesh cloth plate 92 is moved to the feeding rack 23 by the transport member 24, and the mesh cloths 91 on the mesh cloth plate 92 are adsorbed one by one and transferred to the transfer platform 3 by the feeding adsorption member 21. In order to prevent the mesh cloth plate 92 from loosening, the mesh cloth plate 92 is also sucked and fixed in place by adsorption on the feeding rack 23.

[0026] Moreover, in order to recycle the empty trays, the loading assembly 2 further includes a recovery rack 25 , and the transport member 24 is also used to transport the empty mesh tray 92 on the loading rack 23 to the recovery rack 25 .

[0027] In the embodiment of the present invention, the transfer platform 3 is provided with a mounting seat 31, and the mounting seat 31 is provided with a plurality of placement positions for mounting meshes 91. It is convenient to drive a plurality of meshes 91 to be transferred together, and it is also convenient to be opposite to a plurality of assembly manipulators 4 to realize taking out and loading of a plurality of meshes 91 at a time.

[0028] like Figure 6 As shown, in the embodiment of the present invention, the specific structure of the assembly robot 4 is as follows: it includes a positioning plate 41, a rotating plate 42 rotatably arranged on the positioning plate 41, a driving member driving the rotating plate 42 to rotate relative to the positioning plate 41, and a suction pen 43 arranged on the rotating plate 42, and the suction pen 43 can move up and down relative to the rotating plate 42, and it drives the rotating plate 42 to rotate through the driving member, thereby driving the suction pen 43 on the rotating plate 42 to rotate to a tilted state.

[0029] Specifically, the rotating plate 42 is provided with a plurality of adsorption pens 43 arranged side by side, and the assembly manipulator 4 further comprises a moving assembly connected to the positioning plate 41, and the moving assembly is used to drive the plurality of adsorption pens 43 to translate on the body 1. In this solution, the positioning plate 41 is provided with four adsorption pens 43 arranged side by side, and the position intervals thereof correspond to the four earphone shells of the carrier plate 51, so that multiple installations can be achieved in one action.

[0030] like Fig.11 , Fig.12 As shown, in order to achieve alignment assembly, the present solution further provides a pressing assembly 6 on the body 1, and the pressing assembly 6 is used to extend into the earphone housing 90 to press the mesh 91 into the installation position 901. Similarly, a lifting mechanism 53 is also provided at the position opposite to the pressing assembly 6. After the mesh is installed on the carrier plate 51 on the assembly assembly 5, it is moved to the next position, which can be carried by a manipulator or the like. In the present solution, a lifting mechanism 53 is also provided at the next position, which can detect whether the mesh is installed in the corresponding earphone housing after lifting, and then transport it to the position corresponding to the pressing assembly 6 after the detection is completed. In this embodiment, the pressing assembly 6 includes a plurality of pressing fingers 61 corresponding to the positions of the earphone shells on the carrier plate 51. The pressing fingers 61 can move downward into the earphone shells. Similarly, since the earphone shells are in a horizontal position, the up and down movement thereof is to enter the earphone shells in a direction perpendicular to the earphone shells. At this time, the pressing fingers 61 can be directly opposite to the mesh cloth and the mesh cloth mounting position. After the pressing fingers 61 move downward into the earphone shells, the pressing fingers 61 can also be driven by the pushing assembly 62 to move horizontally toward the mesh cloth mounting position, thereby achieving the function of pressing the mesh cloth.

[0031] In this solution, the machine body 1 is further provided with a discharging assembly, which includes a feeding platform 71 and a handling robot 72 for carrying the carrier 51 to the feeding platform 71. After completing the above series of assembly actions, ensure that the mesh cloth is installed on the earphone shells on the carrier 51, and then the handling robot 72 carries the carrier 51 to the feeding platform 71, and uses the feeding platform 71 to achieve docking with the next station assembly mechanism.

[0032] The present invention provides an automatic assembly device for earphone mesh, wherein a loading component takes out a single mesh and places the mesh on a transfer platform, and after being taken out by an assembly robot, the mesh is placed on a carrier plate for installation to complete the automatic assembly. In addition, the present solution is suitable for a recessed position in a single-sided shell where the installation position cannot be directly placed. After the carrier plate is rotated from a horizontal state to an inclined state by the assembly component, the assembly robot is rotated to a certain tilt angle, and then the mesh is placed in to complete the assembly.
