[0056] On the one hand, wrapping the outer shell with cloth can increase the shell's aesthetic performance, and on the other hand, it also has a dust-proof effect for hollow shells. Generally, it is used more on the outer shell of audio equipment. The existing cloth wrapping process generally uses hot melt adhesive to bond the mesh cloth and the shell body. When wrapping, some use spraying hot melt adhesive, and some use pre-bonded hot melt adhesive film. However, there are problems such as high cost of adhesive film and uneven spraying thickness. In addition, some structures use local hot melt welding for bonding, which will also cause thermal deformation of the sound shell.

[0057] See also Figure 2-Figure 11 A processing device for a clamping ring type mesh cloth shell is used to wrap a mesh cloth 720 outside a shell 710 and fix the mesh cloth 720 in the shell 710 through a clamping ring 730. The processing device includes: a profiling lower mold 100, a mesh cloth stretching mechanism 200, a mesh cloth fastening mechanism, a mesh cloth cutting mechanism and a clamping ring mechanism 300. The profiling lower mold 100 is used to support the shell 710. The profiling lower mold 100 includes a support shaft 110 and a mold core 120 arranged on the support shaft 110. The mold core 120 cooperates with the inner wall of the shell 710. The support shaft 110 is provided with a ring knife 111 for cutting the cloth; the mesh cloth stretching mechanism 200 is provided with a lower mold hole 240 for the profiling upper mold 400 to pass through, and the mesh cloth stretching mechanism 200 can reciprocate in the vertical direction. The mesh cloth stretching machine The structure 200 includes an upper middle plate 210, a lower middle plate 220 and a closing assembly 230. The mesh 720 is arranged between the upper middle plate 210 and the lower middle plate 220. The closing assembly 230 is arranged above the lower middle plate 220. The closing assembly 230 can shrink the mesh 720 inward along the radial direction; the mesh fastening mechanism is arranged at the upper part of the mesh stretching mechanism 200, and is used to fix the stretched mesh 720 on the outside of the shell 710; the mesh cutting mechanism is arranged between the lower middle plate 220 and the mesh fastening mechanism, and is used to cut off the shrunk mesh 720; the clamping ring mechanism 300 is sleeved on the support shaft 110, and the clamping ring mechanism 300 can drive the clamping ring 730 to move in the direction of the support column until the clamping ring 730 fixes the mesh 720 in the shell 710.

[0058] It can be understood that the core 120 of the contoured lower mold 100 supports the shell 710, the upper middle plate 210 and the lower middle plate 220 clamp the mesh 720 and allow the shell 710 to pass through the upper middle plate 210 and the lower middle plate 220 by moving downward, thereby stretching the mesh 720 on the shell 710, and then tightening the mesh 720 through the closing assembly 230, the mesh fastening mechanism fixes the stretched mesh 720 on the outside of the shell 710, and then the mesh cutting mechanism cuts the mesh 720, and the mesh 720 is still in a closed state after being cut, the snap ring mechanism 300 moves upward, and the closing part of the mesh 720 is in the gap between the snap ring seat 330 and the support shaft 110, the snap ring mechanism 300 continues to move upward until the snap ring 730 is pushed into the shell 710, so that the mesh 720 can be folded and fixed in the shell 710 by the snap ring 730.

[0059] See also Figure 3 and Fig.11 In some embodiments, in order to improve the structural stability of the processing equipment and enhance the compactness of the structure, the profiling lower mold 100, the mesh stretching mechanism 200, the mesh fastening mechanism and the clamping ring mechanism 300 are all installed on the frame 600, and the frame 600 includes a bottom plate 610, a top plate 620 and a support plate 630 connected between the bottom plate 610 and the top plate 620. The number of the support plates 630 is four, and the four support plates 630 are arranged near the four corners of the bottom plate 610 and the top plate 620.

[0060] Furthermore, the support shaft 110 of the contoured lower die 100 is arranged at the center position of the bottom plate 610, and the support shaft 110 is fixed to the bottom plate 610 through the base 130. The bottom plate 610 is provided with a third telescopic assembly 211 for driving the upper middle plate 210 to reciprocate in the vertical direction. The number of the third telescopic assemblies 211 is four, and the third telescopic assemblies 211 are arranged on the bottom plate 610 and located at the four corners of the bottom plate 610. The two ends of the upper middle plate 210 are respectively connected to the third sliders 6313. When the third telescopic assembly 211 drives the upper middle plate 210 to reciprocate in the vertical direction, the two ends of the upper middle plate 210 can slide on the first linear guide rail 6311, which can ensure the smooth operation of the upper middle plate 210 to increase the stability of the structure; refer to Figure 7A fourth telescopic component 221 is also provided on the bottom plate 610 for driving the lower middle plate 220 to reciprocate in the vertical direction. There are two fourth telescopic components 221, and the fourth telescopic components 221 pass through the bottom plate 610. The upper end of the fourth telescopic component 221 is connected to the lower middle plate 220, and both sides of the lower middle plate 220 are connected to the second slider 6322. When the fourth telescopic component 221 drives the lower middle plate 220 to reciprocate in the vertical direction, the lower middle plate 220 can slide on the second linear guide rail 6321, thereby ensuring the smooth operation of the lower middle plate 220 to increase the stability of the structure.

[0061] In some embodiments, the closing assembly 230 can be provided to tighten the opening of the mesh 720 through the closing assembly 230, so that the mesh 720 on the shell 710 is flat and wrinkle-free. The closing assembly 230 can be any mechanism that can shrink radially, for example, by pushing the slider to shrink inward through multiple telescopic mechanisms to achieve the purpose of closing. Preferably, in this embodiment, the closing assembly 230 includes multiple blades 232, and the multiple blades 232 form an annular structure with a through hole at the center. The axis of the annular structure coincides with the axis position of the lower mold hole 240. The multiple blades 232 are respectively connected to the radial driving device, and each blade 232 is driven away from or close to the axis by the radial driving device. By shrinking the blades, the blade thickness is small and the space occupied is small.

[0062] In some embodiments, see Figure 6 The radial drive device is a rotating wheel 231, the axis of the rotating wheel 231 coincides with the axis of the annular structure, the rotating wheel 231 is provided with an arc groove 2311, the blade 232 is provided with a pin 2322, the pin 2322 passes through the arc groove 2311, the upper middle plate 210 is provided with a linear slide 212, the bottom of the blade 232 is provided with a linear slider that can slide in the linear slide 212, the number of the linear slide 212 and the number of the arc groove 2311 are the same as the number of the blades 232, and the distance from one end of the linear slide 212 to the axis is greater than the distance from the other end of the linear slide 212 to the axis. In this embodiment, the rotating wheel 231 drives multiple blades 232 to move radially at the same time, which has a simple structure and a small volume.

[0063] Specifically, the distances from the two ends of the linear slide groove 212 to the axis are different. When the blade 232 slides in the linear slide groove 212 through the linear slider, it can move away from or close to the axis. The provision of the linear slider can ensure that the blade 232 moves in a single direction but cannot rotate, thereby preventing the blade 232 from getting stuck. The pin 2322 on each blade 232 is movably connected to the arc groove 2311 on the rotating wheel 231. When the rotating wheel 231 rotates, each blade 232 can be driven to move at the same time, thereby realizing the tightening action of the blade 232. In one embodiment, when the rotating wheel 231 rotates clockwise, the pin 2322 moves relative to the arc groove 2311 to a position close to the axis, and at the same time drives the blade 232 so that the linear slider at the bottom of the blade 232 moves in the linear slide groove 212 toward the end close to the axis. When the linear slider moves to the end of the linear slide groove 212 close to the axis, the blade 232 is in a tightened state; when the rotating wheel 231 rotates counterclockwise, the pin 2322 moves relative to the arc groove 2311 to a position away from the axis, and at the same time drives the blade 232 so that the linear slider at the bottom of the blade 232 moves in the linear slide groove 212 toward the end away from the axis. When the linear slider moves to the end of the linear slide groove 212 away from the axis, the blade 232 is in an open state.

[0064] Specifically, the blades 232 and the runner 231 are arranged in the sink groove opened on the upper middle plate 210, and the sink groove is provided with a cover plate 235, that is, the cover plate 235 and the upper middle plate 210 form upper and lower supports for the closing component 230, and the number of straight slide grooves 212, the number of arc grooves 2311 and the number of blades 232 are all six, and the six straight slide grooves 212 are distributed in an unconnected regular hexagon, and the center of the regular hexagon coincides with the axis. The runner 231 is projected onto the upper middle plate 210, and the angle at the intersection of the arc groove 2311 and the straight slide groove 212 is 45°-135°. Preferably, when the blade 232 is in the tightened position, the angle at the intersection of the arc groove 2311 and the straight slide groove 212 is 90°. The setting of this angle enables the runner 231 to realize the rotation of the blade 232 with only minimal force. It should be noted that the number of blades 232 is not limited to six.

[0065] In some embodiments, the closing assembly 230 further includes a gear 233, the gear 233 is meshed with the rotating wheel 231, and the gear 233 is connected to the output shaft of the motor 234. That is, the automatic tightening and opening of the blades 232 can be achieved through the rotation of the motor 234.

[0066] Combination Figure 3 and Figure 8In some embodiments, the mesh fastening mechanism includes a contoured upper mold 400 and a contoured slider assembly 500. The contoured upper mold 400 can be pressed against the bottom of the shell to fix the bottom of the shell and the mesh wrapped around the bottom of the shell. The contoured slider assembly 500 can be pressed against the outer side wall of the shell to fix the outer side wall of the shell and the mesh wrapped around the outside of the shell opening.

[0067] Furthermore, the contoured upper mold 400 includes a first telescopic component 410 and an upper mold pressing block 430 connected to the bottom of the first telescopic component 410, and the inner wall of the upper mold pressing block 430 cooperates with the outer wall of the shell.

[0068] Specifically, the first telescopic component 410 is arranged in the middle of the top plate 620, and the first telescopic component 410 and the support shaft 110 are located on the same axis, thereby ensuring that the contoured lower mold 100 and the contoured upper mold 400 can be molded together, the first telescopic component 410 passes through the top plate 620, and the bottom of the first telescopic component 410 is connected to the second connecting plate 420, and the upper mold block 430 is arranged on the second connecting plate 420, and the two ends of the second connecting plate 420 are connected to the first slider 6312, and the second connecting plate 420 can slide on the first linear guide rail 6311, thereby improving the stability of the upper mold block 430 during operation; further, by setting the contoured upper mold 400, after the closing blade 232 tightens the mesh cloth, the mesh cloth on the shell is in a stretched and taut state, the first telescopic component 410 drives the upper mold block 430 to move downward, and the upper mold block 430 presses the mesh cloth against the outer wall of the shell, so that the mesh cloth on the shell can be always in a stretched and wrinkle-free state.

[0069] Combination Figure 3 and Fig.10 In some embodiments, the contoured slider assembly 500 is located at the upper portion of the upper middle plate 210 , and there are multiple contoured slider assemblies 500 , which are surrounded on the outer side wall of the shell.

[0070] Specifically, the number of the contoured slider assemblies 500 is three. The contoured slider assemblies 500 are arranged so that the contoured slider assemblies 500 are located on the side of the shell 710. After the closing blade 232 tightens the mesh 720, the mesh 720 on the shell 710 is in a stretched and taut state. The three contoured slider assemblies 500 move inward at the same time to press the mesh 720 against the outer wall of the shell 710, so that the mesh 720 on the shell 710 is always in a stretched and wrinkle-free state. It should be noted that the number of the contoured slider assemblies 500 is not limited to three.

[0071] Furthermore, the contoured slider assembly 500 includes a slider 510 and a second telescopic assembly 530 for pushing the slider 510 , the slider 510 includes a first connecting surface 511 affixed to the shell and a second connecting surface 512 affixed to the retaining ring seat 330 , and the second connecting surface 512 protrudes from the first connecting surface 511 .

[0072] Specifically, the second telescopic component 530 is fixed on the upper pressure plate, and the slider 510 is fixedly connected to the second telescopic component 530. When the slider 510 is pushed and pressed onto the shell, the first connecting surface 511 of the slider 510 fits with the shell 710, and the second connecting surface 512 of the slider 510 fits with the retaining ring seat 330. It can be understood that the retaining ring seat 330 pushes the retaining ring 730 into the inner side of the shell 710, so the outer diameter of the retaining ring seat 330 is smaller than the outer wall of the shell 710, and the second connecting surface 512 protrudes from the first connecting surface 511, and the second connecting surface 512 is close to the retaining ring seat 330, so that the mesh 720 can be completely pushed into the shell 710.

[0073] Combination Figure 3 and Fig. 9 In some embodiments, the snap ring mechanism 300 further includes a first connecting plate 320 and a fifth telescopic assembly 310 , wherein the first connecting plate 320 is disposed at the bottom of the snap ring seat 330 , and the fifth telescopic assembly 310 is disposed at the bottom of the first connecting plate 320 .

[0074] Specifically, the first connecting plate 320 and the snap ring seat 330 are sleeved on the support shaft 110 , and the first connecting plate 320 is driven by the fifth telescopic assembly 310 to further drive the snap ring seat 330 to move upward, so that the snap ring 730 fixes the mesh 720 on the inner side of the shell 710 .

[0075] Combination Figure 4 In some embodiments, the mesh cutting mechanism can be a laser cutting mechanism arranged between the lower middle plate 220 and the mesh fastening mechanism, or a cutting blade that moves radially inward and retracts. In this embodiment, preferably, the mesh cutting mechanism includes a ring knife 111, and the ring knife 111 is arranged on the support shaft 110. The mesh 720 is contracted by the closing component 230 so that the mesh is tightly attached to the ring knife 111, which makes it easy for the ring knife 111 to cut off excess mesh 720, that is, the closing component 230 cooperates with the ring knife 111 to quickly cut off the mesh, and the structure is simple.

[0076] See also Fig.12 , a method for processing a clamp ring type mesh shell, the method comprising the following steps:

[0077] S1, placing the housing 710 on the core 120 of the contoured lower mold 100;

[0078] The shell 710 has a certain structure inside, and the core 120 should be provided with a structure corresponding to the shell 710. For example, a protruding structure is provided inside the shell 710, and a groove corresponding to the protruding structure is provided on the core 120. Therefore, the shell 710 needs to be placed on the core 120 at a certain angle so that the shell 710 and the core 120 can cooperate.

[0079] S2, placing the mesh 720 on the corresponding position of the lower middle plate 220;

[0080] Combination Figure 7 A positioning coil 222 is provided on the lower middle plate 220, and a marking point 223 is provided on the positioning coil 222. The mesh 720 also has a marking point 223 and the mesh 720 has the same shape as the positioning coil 222. After the mesh 720 is placed on the lower middle plate 220, the mesh 720 should correspond to the position of the marking point 223 on the lower middle plate 220, that is, the mesh 720 is placed on the lower middle plate 220 at a certain angle. Therefore, when each mesh 720 is fixed on the shell 710, the mesh 720 always maintains a certain texture, thereby ensuring the consistency of the cloth wrapping of the shell 710. It should be noted that the marking point 223 can be a small pattern of various shapes, such as a semicircular hole, a rectangular hole, etc.

[0081] S3, the upper middle plate 210 moves downward and clamps the mesh 720 with the lower middle plate 220;

[0082] The third telescopic assembly 211 drives the upper middle plate 210 to move downward until the upper middle plate 210 moves to the upper part of the lower middle plate 220 and fits tightly with the lower middle plate 220, thereby clamping the mesh 720 in the middle.

[0083] S4, the upper middle plate 210 and the lower middle plate 220 move downward at the same time, so that the shell 710 on the profiling lower mold 100 passes through the upper middle plate 210 and the lower middle plate 220, and the profiling lower mold 100 stretches the mesh 720 between the upper middle plate 210 and the lower middle plate 220;

[0084] The bottom of the profiling lower mold 100 is fixed to the bottom plate 610, the profiling lower mold 100 remains stationary, the fourth telescopic component 221 drives the lower middle plate 220 to move downward, and at the same time the third telescopic component 211 drives the upper middle plate 210 to move downward until the shell 710 on the profiling lower mold 100 passes through the upper middle plate 210 and the lower middle plate 220, that is, the mesh cloth 720 is stretched by the shell 710 under the compressed state, and the stretched mesh cloth 720 is consistent with the shape of the shell 710.

[0085] S5, the closing component 230 shrinks the mesh 720;

[0086] The motor 234 drives the wheel 231 to rotate through the gear 233, and then drives the blades 232 to rotate and contract. The inner diameter of the circular ring structure formed by the contracted blades 232 should be larger than the inner diameter of the ring knife 111, that is, the mesh cloth 720 is not cut in this step, and the blades 232 contract to straighten and tighten the mesh cloth 720.

[0087] S6, the mesh fastening mechanism fixes the stretched mesh 720 to the outside of the housing 710;

[0088] After the blades 232 contract to straighten and tighten the mesh 720, the first telescopic component 410 drives the upper molding block 430 to move downward until the upper molding block 430 presses the mesh 720 against the bottom of the shell, and then the second telescopic component 530 drives the slider 510 to move inward until the slider 510 presses the mesh 720 against the surrounding side of the shell 710.

[0089] S7, the mesh cutting mechanism cuts off the shrunk mesh;

[0090] The contoured lower die 100 passes through the mesh 720 stretching mechanism 200 , and the mesh cutting mechanism is a ring knife 111 set on the support shaft and located inside the closing component 230 . When the closing component 230 is tightened, the mesh 720 is pressed against the knife side of the ring knife 111 , and the ring knife 111 cuts the mesh 720 .

[0091] S8, the closing assembly 230 opens, the clamping ring mechanism 300 moves upward, and the mesh 720 is pushed into the shell 710.

[0092] The snap ring seat 330 is sleeved on the outside of the support shaft 110, and a gap is set between the snap ring seat 330 and the support shaft 110. The mesh cloth 720 is still in a closed state after being cut off. The snap ring mechanism 300 moves upward, and the closed part of the mesh cloth 720 is in the gap between the snap ring seat 330 and the support shaft 110. The snap ring mechanism 300 continues to move upward until the snap ring 730 is pushed into the shell 710, so that the mesh cloth 720 can be folded and fixed in the shell 710 through the snap ring 730.
