[0010] In one exemplary embodiment of this disclosure, the second surface is provided with at least two first positioning portions;

[0011] The base is provided with a second positioning part that cooperates with the first positioning part; wherein, at least two of the first positioning parts have different areas and / or shapes on the second surface along the moving direction of the pressing mechanism.

[0028] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided to make this application more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art.

[0029] This disclosure provides an earphone pressing device configured to press an area of ​​an earphone to be pressed.

[0030] like Figure 1 As shown, in the production process of the earphone 7, the earphone 7 includes a pressing area 70 that needs to be pressed by the earphone pressing equipment 1, and a non-pressing area 71 that does not need to be pressed by the earphone pressing equipment 1. The pressing area can be located in the first part 70 of the earphone or in the second part 71 of the earphone.

[0031] Please see Figure 2 , Figure 2 This is a three-dimensional structural diagram of the earphone pressing device 1 in an embodiment of this disclosure. Figure 2 As shown, the headphone pressing device 1 includes a base 3000, a pressing mechanism 20, and a pressing assembly 400. The base 3000 is configured to hold the headphones 7, and the pressing assembly 400 is configured to press the headphones 7 onto the base 3000. The pressing mechanism 20 includes a force transmission member 2022, which is located on the side of the pressing assembly 400 away from the base 3000 and configured to move towards the pressing assembly 400, so that the pressing assembly 400 applies pressure to the headphones 7. Compared to the pressing mechanism 20 moving towards the headphones 7 and directly connecting to and applying pressure to them, this embodiment uses a separate pressing assembly 400 to press the headphones 7 onto the base 3000, providing pre-compression and fixation for the headphones 7. Furthermore, the movement of the force transmission member 2022 towards the pressing assembly 400 reduces the impact of the pressing assembly 400 on the headphones 7 during the application of pressure, ensuring pressing quality.

[0032] It should be noted that the process by which the force transmission component 2022 moves toward the pressing assembly 400 to apply pressure to the earphone 7, as mentioned in this embodiment, can be specifically as follows: First, the pressing assembly 400 presses the earphone 7 onto the base 3000, and the force transmission component 2022 is in its initial position, which is the position where the distance between the force transmission component 2022 and the pressing assembly 400 is at its maximum. Subsequently, the force transmission component 2022 moves toward the pressing assembly 400, and the distance between the force transmission component 2022 and the pressing assembly 400 gradually decreases until the force transmission component 2022 and the pressing assembly 400 just come into contact. After the force transmission component 2022 and the pressing component 400 are just connected: the force transmission component 2022 can continue to move towards the base 3000, and the pressing component 400 can continue to move towards the base 3000 under the drive of the force transmission component 2022 until it is connected to the base 3000. During the process of the pressing component 400 being driven by the force transmission component 2022 to connect with the base 3000, the pressing component 400 will transmit the pressure it receives to the earphone 7 to achieve pressing.

[0033] In some embodiments, during the pressing process, the pressing component 400 and the earphone 7 can be directly connected. A direct connection can be understood as: there is no other structure between the pressing component 400 and the earphone 7, and the two are in direct contact. However, this is not limited to this; the pressing component 400 and the earphone 7 can also be indirectly connected. An indirect connection can be understood as: the pressing component 400 can also indirectly contact the earphone 7 through other structures.

[0034] In some embodiments, such as Figure 2 and Figure 3 As shown, the clamping mechanism 20 includes a drive assembly 201 and a force transmission assembly 202. The drive assembly 201 includes a pusher 2011 located on the side of the clamping assembly 400 opposite to the base 3000. The force transmission assembly 202 includes an elastic member 2021 and a force transmission member 2022, with the elastic member 2021 connected between the force transmission member 2022 and the pusher 2011. The pusher 2011 is configured to move relative to the force transmission member 2022 in a direction toward the force transmission member 2022 to clamp the elastic member 2021.

[0035] In some embodiments, the drive assembly 201 may further include a drive member 2012, and a pusher member 2011 is located on the side of the pressing assembly 400 opposite to the base 3000 and connected to the drive member 2012. An elastic member 2021 is connected between the force transmission member 2022 and the pusher member 2011. The pusher member 2011 is configured to perform a pressing stroke towards the force transmission member 2022 under the drive of the drive member 2012, thereby pressing the elastic member 2021.

[0036] For example, during the pressing of the earphone 7 using the earphone pressing device 1: the earphone 7 is first placed on the base 3000; then, the pressing assembly 400 is aligned and placed on the base 3000 to press the earphone 7 onto the base 3000. Afterwards, the pushing member 2011 moves towards the base 3000, thereby driving the force transmission member 2022 to move towards the base 3000. Specifically, when the force transmission member 2022 just comes into contact with the pressing assembly 400, the pushing member 2011 continues to move towards the base 3000. The driving force transmitted by the pushing member 2011 to the elastic member 2021 causes the elastic member 2021 to be in a compressed state, and the rebound force generated by the elastic member 2021 is transmitted through the force transmission member 2022 to the pressing assembly 400 before being applied to the earphone 7. Subsequently, the pusher 2011 continues to move in the direction of the base 3000, and the force transmission member 2022 pushes the pressing assembly 400 in the direction of the base 3000 until the pressing assembly 400 contacts the base 3000. During the process of the pressing assembly 400 being pushed by the force transmission member 2022 to contact the base 3000, the elastic member 2021 is in a state of further compression.

[0037] In this embodiment, the elastic element 2021 is used as the main part of the force transmission component 202 to apply elastic pressure to the earphone 7. The elastic pressure can provide a uniformly distributed pressure on the earphone 7 to ensure the pressing effect. In addition, the elastic pressure can also reduce the damage to the earphone 7 during the pressing process.

[0038] In some embodiments, such as Figure 3 As shown, the headphone pressing device 1 may also include a bracket 6000. The fixed end of the drive member 2012 can be connected to the bracket 6000, and the moving end of the drive member 2012 is connected to the push member 2011. The bracket 6000 is provided with a guide rail 6001 and a slider 6002 slidably disposed in the guide rail 6001. The extension direction of the guide rail 6001 can be the same as the driving direction of the drive member 2012. The force transmission member 2022 is connected to the slider 6002. This design can ensure the accuracy of the movement trajectory of the force transmission member 2022 during the pressing process and ensure the pressing yield.

[0039] In some embodiments, the force transmission element 2022 and the slider 6002 can be fixed by connecting elements such as screws or bolts.

[0040] In some embodiments, the driving element 2012 may be a quick clamp. The quick clamp is characterized by its small size, simple operation, low cost, and manual pressure application. Specifically, by manually applying pressure to the quick clamp, the slider 6002 is driven to slide along the guide rail 6001 under the guidance of the guide rail 6001.

[0041] In some other embodiments, the quick clamp in the drive unit 2012 may be replaced with a cylinder to achieve drive using a pneumatic method.

[0042] In some embodiments, such as Figure 4 and Figure 5 As shown, the force transmission assembly 202 also includes a fastener 2023. The pusher 2011 and / or the force transmission component 2022 may be fitted onto the fastener 2023, and the elastic component 2021 is fitted onto the fastener 2023.

[0043] In some embodiments, one end of the fastener 2023 passes through the pusher 2011 and connects to the force transmission member 2022, with the pusher 2011 sleeved on the other end of the fastener 2023. An elastic member 2021 is sleeved on the fastener 2023. The pusher 2011 is configured to slide along the fastener 2023 towards or away from the force transmission member 2022. In addition to guiding the sliding of the pusher 2011, the fastener 2023 also provides support for the relative movement of the pusher 2011 and the force transmission member 2022.

[0044] In some embodiments, one end of the fastener 2023 passes through the force transmission member 2022 and is connected to the pusher 2011, while the force transmission member 2022 is sleeved on the other end of the fastener 2023. The force transmission member 2022 is configured to slide along the fastener 2023 in a direction toward or away from the force transmission member 2022. In addition to guiding the sliding of the force transmission member 2022, the fastener 2023 also provides support for the relative movement of the pusher 2011 and the force transmission member 2022.

[0045] For example, fastener 2023 can be a bolt, one end of which passes through pusher 2011 and is connected to force transmission member 2022 in sequence; or, one end of bolt passes through force transmission member 2022 and is connected to pusher 2011 in sequence. Elastic member 2021 can be a spring, which can be sleeved on bolt.

[0046] In some embodiments, the pressure value of the compression headphone 7 can be set by setting the stroke of the drive member 2012 and / or the spring compression amount of the spring member.

[0047] In some embodiments, the number of fasteners 2023 may be multiple, and they may be equal-height bolts. For example, the number of fasteners 2023 may be... Figure 2 The four fasteners 2023 shown are respectively located at the four corners of the pusher 2011 and the force transmission component 2022. This ensures the stability of the connection between the pusher 2011 and the force transmission component 2022, while also providing evenly distributed pressure to the earphone 7 to ensure the pressing effect.

[0048] It should be understood that the number of fasteners 2023 is not limited to four; it can also be two, three, five, six, etc., depending on the specific circumstances, as long as it can ensure that the pressure is evenly distributed for the earphone 7.

[0049] In some embodiments, such as Figure 5 As shown, the pusher 2011 and / or the force transmission member 2022 are provided with a sleeve hole 2024. The pusher 2011 and / or the force transmission member 2022 are sleeved onto the fastener 2023 through the sleeve hole 2024. The diameter of the sleeve hole 2024 is larger than the shaft diameter of the fastener 2023, and the difference is ≥1mm. Specifically, after long-term use, the fastener 2023 may rust. Since the diameter of the sleeve hole 2024 is larger than the shaft diameter of the fastener 2023, even if the fastener 2023 rusts, it will not hinder the pusher from moving relative to the force transmission member 2022 along the fastener 2023, ensuring that the performance of the headphone pressing device 1 remains stable after long-term use. Preferably, the difference between the diameter of the sleeve hole 2024 and the shaft diameter of the fastener 2023 can be 1.5mm.

[0050] In some embodiments, such as Figure 6As shown, the pressing mechanism 20 moves toward the pressing assembly 400, such that before the pressing assembly 400 applies pressure to the earphone 7, a first gap h1 exists between the pressing assembly 400 and the base 3000 along the moving direction of the pressing mechanism 20. The first gap h1 ranges from 0.5 to 1.5 mm. Specifically, the earphone 7 is first placed on the base 3000, and then the pressing assembly 400 further presses the earphone 7 onto the base 3000. At this time, the earphone 7 supports the pressing assembly 400. Before the pressing mechanism 20 moves toward the pressing assembly 400, a gap exists between the pressing assembly 400 and the base 3000, which facilitates the pressing assembly 400 transmitting pressure to the earphone 7 under the drive of the pressing mechanism 20. Preferably, the gap height is 0.8 mm. After the earphone 7 is placed on the base 3000, the pressing assembly 400 presses the earphone 7 onto the base 3000. Before the pressing mechanism 20 moves toward the pressing assembly 400 to apply pressure to the earphone 7, the worker can visually estimate the flatness of the pressing assembly 400 and the base 3000, that is, visually estimate whether the gap between the pressing assembly 400 and the base 3000 is completely consistent. If the gap between the pressing assembly 400 and the base 3000 is not completely consistent, it may be that the earphone 7 itself has unreasonable deformation, or that the position of the earphone 7 on the base 3000 is offset compared to its normal position, or that foreign impurities have entered the space where the gap between the pressing assembly 400 and the base 3000 is located. The worker can make a preliminary judgment on whether the earphone pressing device 1 is in good working order by visual inspection, and adjust the earphone pressing device 1 to ensure the pressing quality. For example, the worker can also use a plug gauge to check the flatness between the pressing assembly 400 and the base 3000.

[0051] In some embodiments, such as Figure 2 and Figure 6As shown, the pressing assembly 400 may include a first pressing member 4010. The first pressing member 4010 has a first surface 4011 on the side away from the base 3000 and a second surface 4012 on the side closer to the base 3000. During the movement of the force transmission member 2022, the force transmission member 2022 connects to the first surface 4011 and applies pressure to the first pressing member 4010 through the first surface 4011, causing the first pressing member 4010 to move towards the base 3000. The second surface 4012 connects to the base 3000. At this time, the first gap h1 is 0. Specifically, when the first gap h1 is 0, the second surface 4012 is connected to the base 3000. Even if the pressing mechanism 20 provides excessive pressure to the pressing assembly 400, the pressing assembly 400 will not continue to move towards the base 3000, thus preventing excessive pressure from being further transmitted to the earphone 7 and avoiding damage to the earphone 7. After the headphone pressing device 1 is installed, the worker needs to check the flatness between the first surface 4011 and the force transmission component 2022. Specifically, at this time, the headphone 7 is not installed in the headphone pressing device 1, and the first pressing component 4010 is pressed against the base 3000. The worker operates the clamping mechanism 20 to move towards the pressing assembly 400. Under the drive of the clamping mechanism 20, the distance between the force transmission component 2022 and the first pressing component 4010 becomes smaller. The worker uses a plug gauge to check the flatness between the first surface 4011 and the force transmission component 2022. If the flatness between the first surface 4011 and the force transmission component 2022 does not meet the production standard, the position of the force transmission component 2022 relative to the slider 6002 can be adjusted after loosening the screws or bolts that fix the force transmission component 2022 and the slider 6002 to meet the flatness requirements between the first surface 4011 and the force transmission component 2022. After the plug gauge inspection is qualified, the screws or bolts that fix the force transmission component 2022 and the slider 6002 should be tightened to ensure that the force transmission component 2022 uniformly transmits pressure to the pressing assembly 400, so that the pressing assembly 400 can uniformly transmit pressure to the earphone 7, thereby ensuring the pressing quality. Preferably, the flatness between the first surface 4011 and the force transmission component 2022 is <0.05mm.

[0052] It is worth noting that the specific operating procedure for checking the flatness between two components with plug gauges can be found in section 5.4.1.2 of the National Standard GB / T11337-2004 Flatness Error Detection Standard.

[0053] In some embodiments, such as Figure 7As shown, the second surface 4012 of the first pressing member 4010 is provided with at least two first positioning parts 4013, and the base 3000 is provided with a second positioning part 3003 that cooperates with the first positioning parts 4013. The areas and / or shapes of the projections of the at least two first positioning parts 4013 onto the second surface 4012 along the moving direction of the pressing mechanism 20 are different. Specifically, the force transmission component 2022 moves toward the pressing assembly 400 so that after the pressing assembly 400 applies pressure to the earphone 7, the first pressing component 4010 connects with the base 3000. The first positioning part 4013 and the second positioning part 3003 are configured to position and cooperate during the pressing process. At least two first positioning parts 4013 have different projection areas and / or shapes on the second surface 4012 along the moving direction of the pressing mechanism 20. This ensures that when the worker correctly installs the first pressing component 4010 and the base 3000, the first positioning part 4013 and the second positioning part 3003 can smoothly cooperate and connect, thereby ensuring the accuracy of the pressing alignment and thus ensuring the pressing effect.

[0054] Specifically, one of the first positioning part 4013 and the second positioning part 3003 can be a protrusion with a different projected area and / or shape on the second surface 4012 along the moving direction of the pressing mechanism 20, and the other is a groove for the protrusion to be inserted.

[0055] For example, the first positioning part 4013 and the second positioning part 3003 may be pin holes with different projected areas and / or shapes on the second surface 4012 along the moving direction of the pressing mechanism 20, and the positioning engagement between the first pressing part 4010 and the base 3000 is achieved by cooperating with the pins.

[0056] In some embodiments, such as Figure 8 As shown, the base 3000 includes a first contoured recessed area 3002, wherein the first part 70 of the earphone 7 is placed in the first contoured recessed area 3002, and the gap between the first contoured recessed area 3002 and the first part 70 is zero. The first contoured recessed area 3002 supports the earphone 7 while also limiting its position, reducing the earphone 7's shaking. Simultaneously, the contoured structure of different shapes determines the placement orientation of the earphone 7, preventing it from being placed upside down.

[0057] In some embodiments, such as Figure 6 and Figure 9As shown, the pressing assembly 400 further includes a second pressing member 4020, and the second surface 4012 further includes a second recessed area 4014. The second recessed area 4014 accommodates at least a portion of the second pressing member 4020. The second pressing member 4020 is provided with a third recessed area 4021. The third recessed area 4021 is provided with a connecting portion 4022 and a non-connecting portion 4023. The connecting portion 4022 can connect with the pressing area 72 of the earphone 7 and transmit pressure to the pressing area 72. When the pressing assembly 400 presses the earphone 7 onto the base 3000, there is a second gap h2 between the non-connecting portion 4023 and the non-pressing area 73 of the earphone 7. The value of the second gap h2 is ≥0.05mm. Specifically, after the earphone 7 is placed on the base 3000 and when the pressing assembly 400 presses it onto the earphone 7, in the moving direction of the pressing mechanism 20, the connecting portion 4022 is closer to the earphone 7 than the non-connecting portion 4023. The force transmission component 2022 moves toward the pressing assembly 400 so that when the pressing assembly 400 applies pressure to the earphone 7, the connecting portion 4022 connects to the area to be pressed 70 and transmits the pressure, while the non-connecting portion 4023 is not connected to the earphone 7. This ensures that even if the non-pressing area 71 protrudes from the area to be pressed 70, the non-connecting portion 4023 can avoid the non-pressing area 71, thereby preventing the area to be pressed 70 from being unable to receive the pressure transmitted by the second pressing component 4020 after the non-pressing area 71 is mistakenly pressed, thus ensuring production quality. Preferably, the value of the second gap h2 is 0.1 mm.

[0058] In this embodiment, the connecting part 4022 connects to the pressing area 70 and transmits pressure. While ensuring that the pressure is evenly transmitted to the pressing area 70, it also makes it easy to replace the second pressing part 4020 that meets the requirements according to the shape of the earphone 7, so that the entire earphone pressing device 1 does not need to be replaced, thus reducing costs. In addition, it can also improve the versatility of the earphone pressing device 1.

[0059] In some embodiments, the first pressing member 4010 and the second pressing member 4020 may be connected together by bolts, but are not limited thereto; they may also be connected by magnetic attraction, depending on the specific circumstances.

[0060] In some embodiments, the second pressing member 4020 can be a plastic or rubber part, preferably made of Teflon. When excessive force is applied, the plastic / rubber second pressing member 4020 has a certain degree of elasticity, making it less likely to damage the earphone 7.

[0061] In some embodiments, the base 3000 is further provided with a fourth recessed area 3004, which is configured to accommodate the second part 71 of the earphone 7. Specifically, the fourth recessed area 3004 can be configured as a contoured structure that matches the second part 71, that is, when the second part 71 is placed in the fourth recessed area 3004, there is no gap between the second part 71 and the fourth recessed area 3004, which can limit the earphone 7 and reduce the shaking of the earphone 7. Alternatively, the shape of the fourth recessed area 3004 can also be configured to approximately match the second part 71, that is, after the second part 71 is inserted into the fourth recessed area 3004, there is still a gap between the second part 71 and the fourth recessed area 3004, which can both limit the earphone 7 and prevent the second part 71 from being damaged.

[0062] In some embodiments, such as Figure 10 As shown, the headphone pressing device 1 also includes a fixing member 5000, which is pressed onto the headphone 7. The first part 70 of the headphone 7 is pressed onto the pressing assembly 400, and the second part 71 of the headphone 7 is pressed onto the fixing member. Specifically, the second part 71 is both limited by a fourth recessed area 3004 and pressed onto the headphone 7 by the fixing member 5000, thereby effectively fixing the second part 71 and reducing the shaking of the second part 71.

[0063] In some embodiments, the projection of the first pressing member 4010 onto the base 3000 along the moving direction of the pressing mechanism 20 overlaps at least partially with the projection of the fixing member 5000 onto the base 3000 along the moving direction of the pressing mechanism 20. Specifically, when the pressing assembly 400 presses down on the first part 70, if the second part 71 flips over, causing the fixing member 5000 to be lifted, the first pressing member 4010 can abut against the fixing member 5000, thus limiting its movement and preventing the fixing member 5000 from being completely pushed open by the earphone 7.

[0064] In some embodiments, the fastener 5000 and the base 3000 can be connected by bolts, but are not limited to this; they can also be fixed by magnetic attraction, depending on the specific circumstances.
