[0058] Figure 1 This is a schematic structural diagram of a speaker grille packaging device provided by an embodiment of the present invention at one viewing angle;

[0059] Figure 2 FIG. 1 is a structural diagram of the speaker grille packaging device provided by an embodiment of the present invention from another perspective. Figure 1-Figure 2 As shown, this embodiment provides a speaker mesh packaging device, which includes a frame 1, a carrying mechanism 2, a pressing mechanism 3 and a wrapping mechanism 4; the carrying mechanism 2 is arranged on the frame 1, and the carrying mechanism 2 is used to carry the speaker body; the pressing mechanism 3 is arranged on the frame 1 and is located above the carrying mechanism 2, and the pressing mechanism 3 can press the mesh cover on the top of the speaker body; the wrapping mechanism 4 includes a wrapping drive part 41 and two wrapping parts 42 (see Figure 6 ), the two wrapping parts 42 are respectively located on both sides of the supporting mechanism 2, and the wrapping driving part 41 is arranged on the frame 1. The wrapping driving part 41 can drive the two wrapping parts 42 to wrap the mesh cover on the outer surface of the speaker body along the outer contour of the speaker body.

[0060] In the speaker grille packaging device provided in this embodiment, the frame 1 serves as an integral support for the supporting mechanism 2, the pressing mechanism 3, and the wrapping mechanism 4. The supporting mechanism 2 is used to support the speaker body. The pressing mechanism 3 is used to press the grille against the top of the speaker body, thereby positioning the grille and the speaker body. The wrapping drive 41 is capable of driving the two wrapping parts 42 to wrap the grille around the outer surface of the speaker body along the outer contour of the speaker body. Through the interaction between the supporting mechanism 2, the pressing mechanism 3, and the wrapping mechanism 4, an automated packaging process for the speaker body and grille is achieved, reducing the workload of operators and labor costs. Furthermore, the packaging efficiency is high, the packaging quality is good, and the yield rate of the finished product can be improved.

[0061] For the convenience of description, Figure 1 As shown, the length direction of the rack 1 is defined as the X direction, the width direction of the rack 1 is defined as the Y direction, and the height direction of the rack 1 is defined as the Z direction. The X direction, the Y direction, and the Z direction only represent three spatial directions that are perpendicular to each other and have no practical meaning.

[0062] Furthermore, in this embodiment, the support mechanism 2 is composed of a plurality of support blocks, each of which is provided with a support slot, and the slot walls of each support block are capable of conforming to the outer wall of the corresponding portion of the speaker body. When manufacturing the support mechanism 2, the number of support blocks and the shape of the support slots on each support block can be determined through a combination of simulation and experimental verification to accurately match the outer surface of the corresponding speaker body, thereby achieving stable support for the speaker body and preventing displacement during the mesh wrapping process, which could affect the wrapping quality.

[0063] There are many different types of speakers currently available on the market. To accommodate the grille wrapping of speaker bodies of varying sizes, in this embodiment, the support mechanism 2 is detachably connected to the frame 1. When grille wrapping of speaker bodies of varying sizes is required, the support mechanism 2 can be replaced to match the corresponding speaker body, thereby increasing the versatility of the speaker grille wrapping device. Optionally, each support block is connected to the frame 1 via fasteners, facilitating both assembly and disassembly.

[0064] In addition, dividing the supporting mechanism 2 into multiple supporting blocks and processing them separately can simplify the processing technology, and the speaker bodies of different specifications may have some outer surfaces with the same shape. In this case, the corresponding supporting blocks can be used universally, thereby reducing the material used in the supporting mechanism 2 and reducing the processing cost.

[0065] Furthermore, if Figure 1 As shown, the ram mechanism 3 includes a ram lift driver 31 and a ram 32. The ram lift driver 31 is disposed on the frame 1. The ram 32 is connected to the output end of the ram lift driver 31 and can be raised and lowered under the drive of the ram lift driver 31. In this embodiment, the ram lift driver 31 is a lifting cylinder or other mechanism capable of achieving linear drive.

[0066] Furthermore, a buffer spring is provided between the pressure head lifting drive 31 and the pressure head 32. When the pressure head 32 descends to contact the mesh cover on the top of the speaker body, as the pressure head 32 continues to descend, it can compress the buffer spring, thereby buffering the impact force of the pressure head 32 on the speaker body to ensure the appearance quality of the finished speaker.

[0067] Optionally, a buffer member may be provided at the bottom of the pressure head 32 to further ensure a buffering effect between the pressure head 32 and the speaker body. In this embodiment, the buffer member is made of rubber material, which has a good buffering effect, is easy to obtain, and has a low manufacturing cost.

[0068] Figure 3 1 is a schematic structural diagram of a stand 12 of a speaker grille packaging device provided in an embodiment of the present invention; Figure 4: is a schematic structural diagram of the wrapping portion 42 of the speaker grille packaging device provided by an embodiment of the present invention at a viewing angle. Figure 3-Figure 4 As shown, the frame 1 is provided with two track grooves 121, which correspond one-to-one to the two wrapping parts 42; the wrapping mechanism 4 also includes a sliding member 43, each of which is provided on the wrapping part 42, and the sliding member 43 slides in the corresponding track groove 121. It should be noted that the shape of the track groove 121 provided on the frame 1 is obtained after multiple simulations and experimental verifications. On the one hand, it can achieve stability when the wrapping part 42 is raised and lowered in the vertical direction; on the other hand, when the wrapping part 42 is raised and lowered along the corresponding track groove 121, it can apply a uniform force to the outer surface of the speaker body, ensuring that the grille and the speaker body are firmly adhered, while also preventing the wrapping part 42 from applying too much force on the speaker body, which may affect the appearance quality of the finished speaker.

[0069] Optionally, each sliding member 43 includes a connecting member and a sliding roller rotatably mounted on the connecting member. The connecting member is connected to the wrapping portion 42, and the sliding roller rolls along the groove wall of the track groove 121. By providing the sliding roller, the friction force when the sliding member 43 slides along the track groove 121 can be reduced, reducing the wear between the two and extending the service life of the speaker grille packaging device.

[0070] Different types of speaker bodies have different specifications and sizes. When wrapping the mesh covers on the outer surfaces of different speaker bodies, the movement trajectory of the wrapping part 42 will also be different. In order to improve the versatility of the speaker mesh cover packaging equipment, in this embodiment, the frame 1 includes a supporting plate 11 and a stand 12 erected on the supporting plate 11, and the trajectory groove 121 is opened on the stand 12, and the supporting plate 11 and the stand 12 are detachably connected; the supporting mechanism 2 is detachably arranged on the supporting plate 11, and the pressure head mechanism 3 and the wrapping mechanism 4 are both detachably arranged on the stand 12.

[0071] Optionally, corresponding detachable connections are achieved between the supporting plate 11 and the stand 12, between the pressing head mechanism 3 and the stand 12, and between the wrapping mechanism 4 and the stand 12 through fasteners, which has a simple structure and is easy to process.

[0072] Figure 5 FIG. 4 is a structural diagram of the wrapping portion 42 of the speaker grille packaging device provided by an embodiment of the present invention from another perspective. Figure 4-Figure 5As shown, the wrapping portion 42 includes a Z-direction mounting plate 421, an X-direction mounting plate 422, an adjustment component 423 and a wrapping roller 424. The Z-direction mounting plate 421 is slidably arranged on the frame 1 along the Z direction; the X-direction mounting plate 422 is slidably arranged on the Z-direction mounting plate 421 along the X direction; the adjustment component 423 is arranged on the X-direction mounting plate 422; the wrapping roller 424 is rotatably arranged on the adjustment component 423 and can roll in contact with the outer surface of the speaker body on the supporting mechanism 2; the adjustment component 423 is configured to adjust the relative position between the wrapping roller 424 and the speaker body. By setting up the adjustment component 423, the wrapping roller 424 can be better adapted to the outer surface of the speaker body when moving from top to bottom, and act on the speaker body and the grille with a uniform force, so as to achieve uniform wrapping of the grille on the speaker body. At the same time, it can also avoid the large force exerted by the wrapping roller 424 on the speaker body, which may affect the appearance quality of the finished speaker. By setting up the wrapping roller 424, the friction force on the speaker body and the grille during the wrapping process can also be reduced to ensure the wrapping quality.

[0073] Furthermore, the adjustment assembly 423 includes a first adjustment module, a second adjustment module, a third adjustment module, and an adjustment fixing plate 4231. The first adjustment module is mounted on the X-mounting plate 422. The second adjustment module is connected to the first adjustment module and can adjust the position of the second adjustment module along the Y direction. The third adjustment module is connected to the second adjustment module and can adjust the position of the second adjustment module along the Z direction. The ends of the adjustment fixing plate 4231 are respectively connected to the third adjustment module and the wrapping roller 424, and the third adjustment module can adjust the position of the adjustment fixing plate 4231 along the X direction. Through the interaction between the first, second, and third adjustment modules, the position of the wrapping roller 424 can be adjusted in three dimensions to better adapt to the outer surface of the speaker body.

[0074] Specifically, the first adjustment module includes a first Y-axis adjustment block 4232 and a second Y-axis adjustment block 4233. The first Y-axis adjustment block 4232 is mounted on the X-axis mounting plate 422. The first Y-axis adjustment block 4232 is provided with a plurality of first adjustment holes spaced apart along the Y direction. The second Y-axis adjustment block 4233 is provided with a second adjustment hole. An adjustment member is inserted into the second adjustment hole and any one of the first adjustment holes to securely connect the first and second Y-axis adjustment blocks 4232 and 4233. In this embodiment, the adjustment member is an adjustment screw, the second adjustment hole is a through hole, and the first adjustment hole is a threaded hole. To adjust the speaker body to a different size, the adjustment member can be removed from the first and second adjustment holes, and then the relative position of the first and second Y-axis adjustment blocks 4232 and 4233 can be adjusted. After the positions are adjusted, the adjustment member is then secured to the second adjustment hole and the corresponding first adjustment hole to adjust the Y-axis position of the wrapping roller 424.

[0075] The second adjustment module includes a first Z-direction adjustment block 4234, a second Z-direction adjustment block 4235, a Z-direction sliding block 4236 and a Z-direction spring. The first Z-direction adjustment block 4234 is arranged on the second Y-direction adjustment block 4233. The first Z-direction adjustment block 4234 is provided with a Z-direction slide rail extending along the Z-direction. The Z-direction slide rail 4236 is arranged on the second Z-direction adjustment block 4235 and slides with the Z-direction slide rail. Z-direction springs are arranged between the top of the Z-direction slide rail and the inner top surface of the first Z-direction adjustment block 4234, and between the bottom of the Z-direction slide rail and the inner bottom surface of the first Z-direction adjustment block 4234. When the wrapping roller 424 contacts the surface of the speaker body in the upper half, the force applied by the speaker body to the wrapping roller 424 has an upward component, and the second Z-direction adjustment block 4235 will move upward relative to the first Z-direction adjustment block 4234 under this force, and under the elastic action of the Z-direction spring between the top of the Z-direction slider and the inner top surface of the first Z-direction adjustment block 4234, the wrapping roller 424 is in tight contact with the outer surface of the speaker body, and a uniform force is maintained between the two; when the wrapping roller 424 contacts the surface of the speaker body in the lower half, the force applied by the speaker body to the wrapping roller 424 has a downward component, and the second Z-direction adjustment block 4235 will move downward relative to the first Z-direction adjustment block 4234 under this force, and under the elastic action of the Z-direction spring between the bottom of the Z-direction slider and the inner bottom surface of the first Z-direction adjustment block 4234, the wrapping roller 424 is in tight contact with the outer surface of the speaker body, and a uniform force is maintained between the two.

[0076] The third adjustment module includes a support plate 4237, an X-direction fixed block 4238, an X-direction movable block 4239, and an X-direction spring. The support plate 4237 is mounted on the second Z-direction adjustment block 4235. The X-direction fixed block 4238 and the X-direction movable block 4239 are spaced apart on the support plate 4237 along the X direction. The X-direction movable block 4239 can slide relative to the support plate 4237 along the X direction. An X-direction spring is disposed between the X-direction fixed block 4238 and the X-direction movable block 4239. The end of the X-direction movable block 4239 away from the X-direction fixed block 4238 is connected to the adjustment plate 4231. During the grille wrapping operation, the force exerted by the speaker body on the wrapping roller 424 always has a component in the X direction. This component can push the wrapping roller 424 away from the speaker body, and the X-direction spring maintains a uniform force between the two.

[0077] Furthermore, to match the outer surface of the speaker body, the wrapping roller 424 is a truncated cone-shaped structure. In this embodiment, there are multiple wrapping rollers 424, each having a different bottom diameter, top diameter, and height. One of the multiple wrapping rollers 424 is detachably connected to the adjustment assembly 423. By replacing wrapping rollers 424 of different specifications, the wrapping process for the grille on different models of speaker bodies can be adapted, further improving the versatility of the speaker grille packaging device.

[0078] Further, if Figure 3 and Figure 4 As shown, in order to ensure the stability of sliding between the Z-direction mounting plate 421 and the stand 12, a first slide rail extending along the Z direction is provided on the stand 12, and a first slider is provided on the Z-direction mounting plate 421. The first slider slides in conjunction with the first slide rail to guide the sliding of the Z-direction mounting plate 421 relative to the stand 12.

Figure 6As shown, the wrapping drive unit 41 includes a wrapping lift drive member 411, a lifting screw, a lifting nut, and a lifting connecting plate 412. The output end of the wrapping lift drive member 411 is connected to the lifting screw to drive the lifting screw's rotation. The lifting screw extends in the Z direction. The lifting nut is screwed onto the lifting screw and connected to the lifting connecting plate 412. The ends of the lifting connecting plate 412 are respectively connected to the two wrapping parts 42. Using a single wrapping drive unit 41, the two wrapping parts 42 can be raised and lowered synchronously, reducing the number of wrapping drive units 41, the volume of the speaker grille packaging device, and lowering manufacturing costs. In this embodiment, the wrapping lift drive member 411 is a rotary motor.

[0081] This embodiment provides a speaker grille packaging device. Through the mutual cooperation between the supporting mechanism 2, the pressing head mechanism 3 and the wrapping mechanism 4, an automated packaging process of the speaker body and the grille can be realized, thereby reducing the workload of the operator and lowering labor costs.
