[0043] The embodiments of the present application are described below in combination with the accompanying drawings:

[0044] Reference Figures 1 to 4According to the pressing jig, the pressure maintaining module 100 includes a driving member 110 and a pressure maintaining member 120. In order to ensure that the pressure maintaining member 120 is pressed against and released from the tuning mesh cloth along the X-axis direction, the pressure maintaining member 120 is connected to the output end of the driving member 110 along the X-axis direction, and the driving member 110 can drive the pressure maintaining member 120 to move along the X-axis direction, so that the pressure maintaining member 120 is driven to approach the tuning mesh cloth to be pressed, and the pressure maintaining member 120 is driven to move away from the tuning mesh cloth to be released. In addition, the pressure maintaining member 120 is provided with a pressure head 130 extending along the Z-axis direction, so that at least a part of the pressure maintaining member 120 can enter the inner cavity of the earphone shell along the Z-axis direction.

[0045] The positioning module 200 includes a positioning base 210 and a positioning assembly 220. Along the X-axis direction, the side of the positioning assembly 220 close to the pressure maintaining member 120 is provided with a positioning member 223, and the positioning member 223 is provided with a positioning groove 2231 for positioning and mounting the earphone shell. The groove opening of the positioning groove 2231 is opened towards the Z-axis direction. In the positioning groove 2231, the opening of the inner cavity of the earphone shell is consistent with the direction of the groove opening, and the pressure head 130 can enter the inner cavity of the earphone shell through the groove opening of the positioning groove 2231. In order to facilitate the adjustment of the relative position between the positioning member 223 and the pressure head 130, the positioning member 223 is movably connected to the positioning base 210 along the Y-axis direction and the Z-axis direction, that is, the positioning member 223 can move relative to the positioning base 210 along the Y-axis direction, and can also move relative to the positioning base 210 along the Z-axis direction. The X-axis direction, the Y-axis direction and the Z-axis direction are perpendicular to each other.

[0046] Therefore, by adjusting the position of the positioning member 223 along the Y-axis direction and the Z-axis direction, the pressure head 130 can enter the inner cavity of the earphone shell on the side of the groove opening of the positioning groove 2231. The driving member 110 drives the pressure maintaining member 120 to move along the X-axis direction, and the pressure head 130 presses and maintains the pressure of the tuning mesh cloth. Compared with the manual pressure maintaining mode, the pressing jig in the application can effectively ensure the consistency of the pressure maintaining pressure and the pressure maintaining position, and is beneficial to improve the yield of the earphone.

[0047] Reference Figures 1 to 4, Specifically, the earphone shell is located in the positioning groove 2231 which penetrates along the Z-axis direction, the earphone shell is provided with an inner cavity which penetrates along the Z-axis direction, the tuning mesh cloth is adhered to the inner cavity wall of the earphone shell, the positioning assembly 220 and the positioning base 210 can pass through the cross slide, after the earphone shell is positioned and assembled, the relative position between the positioning piece 223 and the pressure maintaining piece 120 along the Y-axis direction is adjusted, so that the pressure head 130 can be projected in the positioning groove 2231 along the Z-axis direction (at this time, the pressure head 130 and the positioning piece 223 are arranged at intervals along the Z-axis direction), the pressure head 130 extends protruding along the Z-axis direction, and then the position of the positioning piece 223 along the Z-axis direction is adjusted, so that the positioning piece 223 is close to the pressure head 130, and the pressure head 130 can enter the inner cavity of the earphone shell through the slot of the positioning groove 2231. The driving piece 110 can be a structure such as a pneumatic cylinder having a linear driving function, and the pressure maintaining piece 120 is connected to the piston rod of the pneumatic cylinder. The driving piece 110 drives the pressure maintaining piece 120 to move close to the tuning mesh cloth along the X-axis direction, until the pressure head 130 is pressed and combined with the tuning mesh cloth, and the tuning mesh cloth is pressure maintained.

[0048] It should be noted that the size of the pressure maintaining pressure can be adjusted by adjusting the air pressure of the driving piece 110. In addition, in order to ensure the stable pressure maintaining of the pressure head 130 to the tuning mesh cloth, the position of the positioning piece 223 along the Y-axis direction and along the Z-axis direction is finely adjusted, so that the projection of the pressure head 130 along the X-axis direction covers the tuning mesh cloth, and the pressure maintaining position is more consistent,

[0049] Reference Figure 5 and Figure 6 In some embodiments, in order to limit the position of the pressure head 130 after the pressure maintaining operation, the pressure maintaining module 100 further comprises a buffer base 140 and a buffer piece 150, the buffer base 140 is connected with the driving piece 110, and the buffer piece 150 is located on the side of the pressure maintaining piece 120 close to the driving piece 110 along the X-axis direction. The movement of the pressure maintaining piece 120 driven by the driving piece 110 along the X-axis direction away from the tuning mesh cloth can release the tuning mesh cloth, and the buffer piece 150 is used to abut against the pressure maintaining piece 120 to limit the movement distance of the pressure maintaining piece 120, so as to ensure that the inner cavity wall on the opposite side of the pressure head 130 and the tuning mesh cloth has a spacing, and facilitate the movement of the positioning piece 223 along the Z-axis direction relative to the pressure head 130.

[0050] Specifically, after the pressure maintaining, the driving member 110 drives the pressure maintaining member 120 to move in the X-axis direction away from the tuning mesh, so that the pressure head 130 is away from the tuning mesh, and at least a part of the pressure head 130 is located in the inner cavity of the earphone shell. When the pressure maintaining member 120 abuts against the buffer member 150, the pressure head 130 reaches the maximum distance from the tuning mesh, and the inner cavity wall opposite to the pressure head 130 has a spacing. The buffer member 150 further limits the movement stroke of the pressure head 130, which is beneficial to further improve the precision of the driving member 110. The spacing between the pressure head 130 and the earphone shell facilitates the adjustment of the positioning member 223 to make the pressure head 130 exit the inner cavity of the earphone shell.

[0051] Reference Figure 5 and Figure 6 In some other embodiments, along the X-axis direction, the buffer member 150 is provided with a flexible buffer portion 151 at one end close to the pressure maintaining member 120. The flexible buffer portion 151 can be made of silicone, rubber or the like. When the pressure maintaining member 120 abuts against the flexible buffer portion 151 of the buffer member 150, the flexible buffer portion 151 can be deformed to resist the impact of the pressure maintaining member 120 on the flexible buffer portion, so that the contact between the pressure maintaining member 120 and the flexible buffer member 150 is more stable.

[0052] Reference Figure 5 and Figure 6 In some other embodiments, along the direction close to the pressure maintaining member 120, the cross-sectional area of the flexible buffer portion 151 gradually decreases. The pressure maintaining member 120 includes a flexible abutting portion 122, and along the direction close to the flexible buffer portion 151, the cross-sectional area of the flexible abutting portion 122 gradually decreases. The flexible abutting portion 122 is used to abut against the flexible buffer portion 151. When the flexible abutting portion 122 and the flexible buffer portion 151 approach each other, the contact area between the flexible abutting portion 122 and the flexible buffer portion 151 gradually increases, which is beneficial to prolong the buffering time and make the limiting of the pressure maintaining member 120 more gentle.

[0053] Reference Figure 5 and Figure 6 In some embodiments, in order to adaptively adjust the movement stroke of the pressure head 130, along the X-axis direction, the buffer member 150 is movably connected with the buffer base 140. For example, the buffer member 150 is threadedly connected with the buffer base 140. By rotating the buffer member 150 around the X-axis direction, the buffer member 150 can be moved to approach or move away from the pressure maintaining member 120 along the X-axis direction, so as to change the position where the pressure maintaining member 120 abuts against the buffer member 150, and the movement stroke of the pressure head 130 can be adjusted according to the size of the earphone, which is beneficial to further improve the adaptability of the pressure bonding jig to different models of earphones.

[0054] It should be understood that the movement stroke of the pressure head 130 is the maximum distance between the pressure head 130 and the tuning mesh along the X-axis direction.

[0055] Reference Figures 5 to 7 In some embodiments, to ensure the straightness and stability of the pressure maintaining member 120 moving along the X-axis direction, the pressure maintaining module 100 further comprises a guide member 160 arranged extending along the X-axis direction, the pressure maintaining member 120 is provided with a guide groove 121, and a portion of the guide member 160 is located in the guide groove 121, and the pressure maintaining member 120 is in sliding connection with the guide member 160 along the X-axis direction, so that when the pressure maintaining member 120 is driven to move along the X-axis direction, the guide member 160 can provide guidance for the pressure maintaining member 120, so that the straightness of the movement of the pressure maintaining member 120 is better, and thus the pressing head 130 can press the tuning mesh fabric at a more consistent angle.

[0056] Reference Figure 5 In some embodiments, along the Z-axis direction, the guide member 160 can be located below the pressure maintaining member 120, which can provide guidance for the pressure maintaining member 120 and also support the pressure maintaining member 120, further ensuring the position accuracy of the pressing head 130 relative to the tuning mesh fabric along the Z-axis direction, and being beneficial to further improve the consistency of the pressure maintaining operation.

[0057] Reference Figure 6 In some embodiments, the pressing head 130 comprises a main body part 131 and a pressing part 132, the main body part 131 is arranged extending along the Z-axis direction, and the pressing part 132 is connected with the main body part 131 and extends along the X-axis direction away from the driving member 110, so that when the pressing head 130 extends into the inner cavity of the earphone shell, the pressing part 132 can press and maintain the tuning mesh fabric along the X-axis direction, and the main body part 131 has a spacing with the inner cavity wall of the earphone shell, which is beneficial to avoid the inner cavity wall structure of the earphone shell blocking the pressing head 130, and ensure that the pressing part 132 is more uniformly and closely attached to the tuning mesh fabric.

[0058] It should be noted that along the X-axis direction, the area of the outer surface of the side of the pressing part 132 away from the main body part 131 is consistent with the area of the tuning mesh fabric, for example, the tuning mesh fabric is an arc surface structure, the outer surface of the side of the pressing part 132 away from the main body part 131 is an arc surface, and the radii of the two arc surfaces are matched, which is beneficial to the pressing part 132 being more closely attached to the tuning mesh fabric.

[0059] Reference Figure 4 And Figure 5In some embodiments, to ensure that the positioning member 223 moves relative to the positioning base 210 along the Y-axis direction and the Z-axis direction, the positioning assembly 220 further comprises a first moving member 221 and a second moving member 222. The first moving member 221 is movably connected to the positioning base 210 along the Y-axis direction, and the second moving member 222 is movably connected to the first moving member 221 along the Z-axis direction. Along the X-axis direction, the positioning member 223 is connected to the second moving member 222 on the side close to the driving member 110. By moving the first moving member 221 relative to the positioning base 210 along the Y-axis direction, the second moving member 222 and the positioning member 223 can be driven to move relative to the positioning base 210 along the Y-axis direction. By moving the second moving member 222 relative to the first moving member 221 along the Z-axis direction, the positioning member 223 can be driven to move relative to the positioning base 210 along the Z-axis direction, so as to realize the position adjustment of the positioning member 223. The sliding connection between the first moving member 221 and the positioning base 210 and the sliding connection between the first moving member 221 and the second moving member 222 can be realized by the sliding groove and the sliding rail.

[0060] It should be noted that the movement of the first moving member 221 and the second moving member 222 can be driven by a cylinder structure or manually adjusted, and the driving mode of the first moving member 221 and the second moving member 222 is not limited in the present application.

[0061] Reference Figure 4 and Figure 5 In other embodiments, the first moving member 221 is movably connected to the positioning base 210 along the Z-axis direction, the second moving member 222 is movably connected to the first moving member 221 along the Y-axis direction, and along the X-axis direction, the positioning member 223 is connected to the second moving member 222 on the side close to the driving member 110. By moving the first moving member 221 relative to the positioning base 210 along the Z-axis direction, the second moving member 222 and the positioning member 223 can be driven to move relative to the positioning base 210 along the Z-axis direction. By moving the second moving member 222 relative to the first moving member 221 along the Y-axis direction, the positioning member 223 can be driven to move relative to the positioning base 210 along the Y-axis direction, so as to realize the position adjustment of the positioning member 223.

[0062] Reference Figures 5 to 8In some embodiments, the positioning base 210 is provided with a first limiting portion 211 on one side in the Z-axis direction, the first limiting portion 211 is provided with a first limiting through hole 212 penetrating in the Z-axis direction, and the first limiting through hole 212 is arranged extending in the Y-axis direction, for example, the shape of the first limiting through hole 212 can be an oblong through hole, a racetrack-shaped through hole or the like long strip-shaped through hole. The positioning assembly 220 includes a first locking piece 2211, the first locking piece 2211 is connected with the first moving piece 221 and can move together with the first moving piece 221, the first locking piece 2211 is arranged penetrating in the first limiting through hole 212 and extending to one side of the first limiting portion 211 away from the first moving piece 221, so that the first limiting through hole 212 can provide guidance for the first locking piece 2211 moving in the Y-axis direction.

[0063] The first locking piece 2211 has a locked state and an unlocked state, in the locked state, the first locking piece 2211 abuts against the first limiting portion 211 to limit the first locking piece 2211 moving in the Y-axis direction, so as to limit the first moving piece 221 moving in the Y-axis direction, and further, the position of the positioning piece 223 in the Y-axis direction is more determined, and the stability of the pressure maintaining on the tuning mesh is further ensured. In the unlocked state, the first locking piece 2211 is separated from the first limiting portion 211, and the first locking piece 2211 can move in the Y-axis direction to ensure the first moving piece 221 moving relative to the positioning base 210.

[0064] Specifically, the first locking piece 2211 can be threadedly connected with the first moving piece 221, by rotating around the Z-axis direction, the first locking piece 2211 can move in the Z-axis direction relative to the first moving piece 221, so that the first locking piece 2211 can abut against one side of the first limiting portion 211 away from the first moving piece 221, at this time, the first locking piece 2211 is in the locked state, and the friction between the first locking piece 2211 and the first limiting portion 211 can limit the first locking piece 2211 moving in the Y-axis direction relative to the first limiting portion 211, so that the position of the first moving piece 221 is more stable.

[0065] And / or, refer to Figures 5 to 8The first moving part 221 is provided with a second limiting part 2212 on one side in the Y-axis direction. The second limiting part 2212 is provided with a second limiting through hole 2213 penetrating in the Y-axis direction, and the second limiting through hole 2213 extends in the Z-axis direction. For example, the shape of the second limiting through hole 2213 can be an oblong through hole, a racetrack-shaped through hole or the like. The positioning assembly 220 comprises a second locking part 2221 connected with the second moving part 222 and capable of moving together with the second moving part 222. The second locking part 2221 penetrates the second limiting through hole 2213 and extends to the side of the second limiting part 2212 away from the second moving part 222. Thus, the second limiting through hole 2213 can guide the movement of the second locking part 2221 in the Z-axis direction.

[0066] The second locking part 2221 has a locked state and an unlocked state. In the locked state, the second locking part 2221 abuts against the second limiting part 2212 to limit the movement of the second locking part 2221 in the Z-axis direction, thereby limiting the movement of the second moving part 222 in the Z-axis direction.
