Description

Technical Field

[0001] The invention belongs to the technical field of acoustic mesh processing, and in particular relates to a manufacturing device for an acoustic mesh assembly. Background Art

[0002] Acoustic mesh is a component used in products such as loudspeakers (horns). In the prior art, glue or double-sided tape is provided on the mesh, and then the mesh is bonded to the component of the corresponding product through glue or double-sided tape. In order to ensure that the mesh can be effectively bonded to the component of the product and can perform its functions, it is often necessary to design the mesh to be larger in size to ensure that there is enough area to contact and fit with the component of the product, so as to improve the stability and reliability of the bonding. However, the material cost of the mesh is relatively high.

[0061] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. Figures 1 to 5 The described embodiments are exemplary and are intended to be used to explain the embodiments of the present invention, but should not be construed as limiting the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0064] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0065] In one embodiment of the present invention, Figure 1 As shown, an apparatus for manufacturing an acoustic mesh assembly is provided, comprising a frame 180 and a blue film unloading mechanism 10, a base film unloading mechanism 20, a single-sided adhesive unloading mechanism 30, a silicone tape unloading mechanism 40, a silicone tape waste collection mechanism 50, a low-viscosity film unloading mechanism 60, a low-viscosity film waste collection mechanism 70, and a mesh unloading mechanism 80 mounted on the frame 180. It is understood that the blue film unloading mechanism 10, the base film unloading mechanism 20, the single-sided adhesive unloading mechanism 30, the silicone tape unloading mechanism 40, the silicone tape waste collection mechanism 50, the low-viscosity film unloading mechanism 60, the low-viscosity film waste collection mechanism 70, and the mesh unloading mechanism 80 can be unloaded and collected by rotating a motor-driven drum. The blue film 194, base film 191, single-sided adhesive tape, silicone tape, low-viscosity film, and mesh 192 can all be stored in rolls. At the same time, the waste materials collected by the silicone tape waste collection mechanism 50 and the low-viscosity film waste collection mechanism 70 can also be stored in the form of rolls.

[0066] Furthermore, within the frame 180, a first rolling assembly 10a, a first cutting assembly 20a, a second rolling assembly 10b, a third rolling assembly 10c, and a second cutting assembly 20b are sequentially arranged along a conveying direction. The rolling assemblies have gaps through which the layers or films pass. Pressure is applied to the layers or films passing through these gaps, thereby achieving adhesion between the layers or films. Furthermore, the first rolling assembly 10a, the first cutting assembly 20a, the second rolling assembly 10b, the third rolling assembly 10c, and the second cutting assembly 20b can all use friction to move the layers or films forward, i.e., along the conveying direction.

[0067] Furthermore, the blue film unloading mechanism 10 is used to convey the blue film 194 along the conveying direction and make the blue film 194 pass through the first rolling assembly 10a, the first cutting assembly 20a, the second rolling assembly 10b and the second cutting assembly 20b in sequence. The blue film 194 is arranged with its adhesive side facing the direction.

[0068] Furthermore, the base film unloading mechanism 20 is used to convey the base film 191 to the first cutting assembly 20a and apply the base film 191 to the lower surface of the blue film 194. The first cutting assembly 20a cuts the base film 191 and the blue film 194 to form blue film hole waste. The base film 191 applied to the lower surface of the blue film 194 protects the blue film 194. Simultaneously, the first cutting assembly 20a can cut holes at predetermined locations in the base film 191 and the blue film 194.

[0069] Furthermore, the single-sided adhesive discharge mechanism 30 is used to convey the single-sided adhesive layer 193 to the first cutting assembly 20a, and to attach the single-sided adhesive layer 193 to the upper surface of the blue film 194. The first cutting assembly 20a then cuts the single-sided adhesive layer 193 to form single-sided adhesive hole waste. The single-sided adhesive layer 193 is attached to the upper surface of the blue film 194. Similarly, the single-sided adhesive layer 193 can be cut by the first cutting assembly 20a to form holes in the single-sided adhesive layer 193. These holes are used to bond the mesh 192.

[0070] Furthermore, the silicone tape unloading mechanism 40 is used to convey the silicone tape to the third rolling assembly 10c and attach the silicone tape to the single-sided adhesive layer 193 passing through the third rolling assembly 10c. The silicone tape is adhered to the cut single-sided adhesive layer 193.

[0071] Furthermore, the silicone tape waste collection mechanism 50 is used to recycle the silicone tape attached to the single-sided adhesive layer 193 and discharge the single-sided adhesive hole waste through the silicone tape. When the silicone tape is recycled by the silicone tape waste collection mechanism 50, the single-sided adhesive hole waste on the single-sided adhesive layer 193 is taken away.

[0072] Furthermore, the low-viscosity film discharge mechanism 60 is used to deliver the low-viscosity film to the second rolling assembly 10b and adhere the low-viscosity film to the base film 191. The low-viscosity film discharged by the low-viscosity film discharge mechanism 60 is adhered to the base film 191 under the rolling action of the second rolling assembly 10b.

[0073] Furthermore, the low-viscosity film waste collection mechanism 70 is used to recycle the low-viscosity film attached to the base film 191 and discharge the blue film hole waste through the low-viscosity film. During the recycling process of the low-viscosity film waste collection mechanism 70, the low-viscosity film is bonded and taken away with the blue film hole waste on the blue film 194.

[0074] Furthermore, the mesh unloading mechanism 80 is used to convey the mesh 192 to the second cutting assembly 20b. After the mesh outer frame is cut by the second cutting assembly 20b, the mesh 192 is attached to the holes of the single-sided adhesive layer 193 cut by the first cutting assembly 20a. After being cut by the second cutting assembly 20b, the mesh 192 is bonded to the holes of the single-sided adhesive layer 193. This allows for smaller mesh 192 designs to be bonded to the single-sided adhesive layer 193. During actual use, the mesh 192 can be bonded to external components through the single-sided adhesive layer 193 without the need for the mesh 192. This reduces production costs while improving bonding stability during use.

[0075] When the acoustic mesh assembly 190 is manufactured using the manufacturing equipment of the acoustic mesh assembly provided by the embodiment of the present invention, the blue film 194 is first transported along the transport direction by the blue film unloading mechanism 10, and the blue film 194 is sequentially passed through the first rolling assembly 10a, the first cutting assembly 20a, the second rolling assembly 10b, the third rolling assembly 10c and the second cutting assembly 20b, and then the bottom film 191 is transported to the first cutting assembly 20a by the bottom film unloading mechanism 20, and the bottom film 191 is attached to the lower surface of the blue film 194 by rolling of the cutting assembly, and then the single-sided adhesive layer 193 is transported to the first cutting assembly 20a by the single-sided adhesive unloading mechanism 30, and the single-sided adhesive layer 193 is attached to the upper surface of the blue film 194 by rolling, and at the same time, the first cutting assembly 20a , the blue film 194 and the bottom film 191 are cut into holes, and then the silicone tape is conveyed to the third rolling assembly 10c by the silicone tape discharge mechanism 40, and the silicone tape is attached to the upper surface of the single-sided adhesive layer 193 by rolling, and then the silicone tape waste collection mechanism 50 recycles the silicone tape, and the single-sided adhesive hole waste is discharged through the silicone tape; at the same time, the low-viscosity film is conveyed to the second rolling assembly 10b by the film discharge mechanism and the low-viscosity film is attached to the bottom film 191, and then the low-viscosity film is recovered by the low-viscosity film waste collection mechanism 70, and the blue film hole waste is discharged through the low-viscosity film, and then the mesh 192 is conveyed to the second cutting assembly 20b by the mesh outer frame provided by the second cutting assembly 20b, and the mesh 192 is attached to the hole of the single-sided adhesive layer 193 to form the acoustic mesh assembly 190. The acoustic mesh assembly 190 produced in this way does not require the mesh 192 to be directly bonded to the product components, so that the size of the mesh 192 can be designed to be smaller, saving costs; in addition, the bonding with the product components is a single-sided adhesive layer 193 made of a softer material, so that it is not easy to fall off after bonding, and the stability and effect of use are better.

[0076] In another embodiment of the present invention, Figure 1As shown, the acoustic mesh assembly manufacturing equipment also includes a fourth roller assembly 10d, a silicone film discharge mechanism 90, and a mesh waste collection mechanism 100; both the silicone film discharge mechanism 90 and the mesh waste collection mechanism 100 are mounted on the frame 180. The structure of the fourth roller assembly 10d is similar or identical to the first roller assembly 10a, the second roller assembly 10b, and the third roller assembly 10c described above. Similarly, the silicone film discharge mechanism 90 and the mesh waste collection mechanism 100 are also implemented using a motor-driven roller rotation structure.

[0077] Furthermore, the silicone film discharge mechanism 90 is used to sequentially convey the silicone film to the fourth rolling assembly 10 d and the second cutting assembly 20 b , and to adhere the silicone film to the mesh 192 .

[0078] Furthermore, the mesh waste collection mechanism 100 is used to recycle the silicone film bonded with the mesh outer frame formed after being cut by the second cutting component 20b.

[0079] Specifically, the silicone film is bonded to the mesh 192 through the silicone film discharge mechanism 90, and the silicone film is firmly bonded to the mesh 192 under the rolling action of the fourth rolling assembly 10d, and then the silicone film is recycled through the mesh waste collection mechanism 100. In this way, the silicone film can be taken away from the cut mesh frame of the mesh 192 to which it is bonded during the recycling process.

[0080] In another embodiment of the present invention, Figure 1 As shown, the manufacturing equipment of the acoustic mesh assembly further includes a silicone film waste collection mechanism 110, which is installed on the frame 180 and is used to recycle the protective paper on the silicone film discharged by the silicone film discharge mechanism 90. Specifically, the silicone film waste collection mechanism 110 recycles the protective paper on the silicone film, that is, preferably, the silicone film itself has the protective paper when it is discharged by the silicone discharge mechanism, and then the protective paper on the silicone film is first recycled by the silicone film waste collection mechanism 110. This reduces manual operations on the one hand, and reduces contamination to the silicone film on the other hand, thereby improving product quality.

[0081] In another embodiment of the present invention, Figures 1-2As shown, the first rolling assembly 10a, the second rolling assembly 10b, the third rolling assembly 10c, and the fourth rolling assembly 10d each include a first bottom roller 100a and a rotating rubber roller 100b. The first bottom roller 100a and the rotating rubber roller 100b are both rotatably mounted on the frame 180. The first bottom roller 100a and the rotating rubber roller 100b are both rotatably mounted on the frame 180, and the first bottom roller 100a and the rotating rubber roller 100b rotate in opposite directions. In other words, the friction generated by the oppositely rotating first bottom roller 100a and the rotating rubber roller 100b can be used to convey the film material along the conveying direction. Furthermore, the rotating rubber roller 100b is located above the first bottom roller 100a and forms a first conveying gap 100c between the rotating rubber roller 100b and the first bottom roller 100a. This first conveying gap 100c is used to convey the film material.

[0082] In another embodiment of the present invention, Figures 1-2 As shown, the first roller assembly 10a, the second roller assembly 10b, the third roller assembly 10c, and the fourth roller assembly 10d all include a first gap adjustment mechanism 100d. The rotating rubber roller 100b is mounted on the first gap adjustment mechanism 100d and can be adjusted by the first gap adjustment mechanism 100d to change the gap value of the first conveying gap 100c. The first gap adjustment mechanism 100d can adjust the width of the first gap, thereby adapting to the production of acoustic mesh assemblies 190 of different thicknesses.

[0083] In another embodiment of the present invention, Figure 1 As shown, the acoustic mesh assembly manufacturing equipment also includes a release film discharge mechanism 120 and a third cutting assembly 20c. The release film discharge mechanism 120 is similar in structure to other discharge mechanisms and is implemented by a motor-driven roller rotation structure, while the third cutting assembly 20c is similar in structure to other cutting assemblies and performs both rolling and cutting functions.

[0084] Furthermore, the release film unloading mechanism 120 and the third cutting assembly 20 c are both installed on the frame 180 , and the third cutting assembly 20 c is located behind the second cutting assembly 20 b along the conveying direction.

[0085] Furthermore, the release film unloading mechanism 120 is used to convey the release film to the third cutting assembly 20c. After the third cutting assembly 20c cuts the release film outer frame, it is attached to the mesh 192, the single-sided adhesive layer 193, and the blue film 194. The release film serves to protect the mesh 192, the single-sided adhesive layer 193, and the blue film 194. When the acoustic mesh assembly 190 is used, the release film needs to be torn off first.

[0086] In another embodiment of the present invention, Figure 1 As shown, the acoustic mesh assembly manufacturing equipment also includes a release film waste collection mechanism 130. Similar in structure to other waste collection mechanisms, this mechanism utilizes a motor-driven roller. This mechanism is used to recover the release film outer frame formed after cutting by the third cutting assembly 20c. Specifically, after bonding, the release film is cut into an outer frame by the third cutting assembly 20c. The cut outer frame is then recovered by the release film waste collection mechanism 130. This fully automated process reduces pollution and improves efficiency and quality.

[0087] In another embodiment of the present invention, Figure 1 and 3 As shown, the first cutting assembly 20a, the second cutting assembly 20b, and the third cutting assembly 20c all include a second bottom roller 200a and a die-cutting rubber roller 200b. The second bottom roller 200a and the die-cutting rubber roller 200b are both rotatably mounted on the frame 180. The second bottom roller 200a and the die-cutting rubber roller 200b are both rotatably mounted on the frame 180, and the second bottom roller 200a and the die-cutting rubber roller 200b rotate in opposite directions. Similarly, the friction generated by the counter-rotating second bottom roller 200a and the die-cutting rubber roller 200b can convey the film material along the conveying direction. In addition, the die-cutting rubber roller 200b also has a cutting function, removing unnecessary material such as the outer frame and inner hole. Furthermore, the die-cutting rubber roller 200b is located above the second bottom roller 200a and forms a second conveying gap 200c between the second bottom roller 200a and the second bottom roller 200a. The width of the second gap can be adjusted by the second gap adjustment mechanism 200d, so that it can be adapted to the production of acoustic mesh assemblies 190 of different thicknesses.

[0088] In another embodiment of the present invention, Figure 1 and 3As shown, the first cutting assembly 20a, the second cutting assembly 20b, and the third cutting assembly 20c all include a second gap adjustment mechanism 200d. The die-cutting rubber roller 200b is mounted on the second gap adjustment mechanism 200d and can be adjusted by the second gap adjustment mechanism 200d to change the gap value of the second conveying gap 200c. The second gap adjustment mechanism 200d can adjust the width of the second gap, thereby adapting to the production of acoustic mesh assemblies 190 of different thicknesses.

[0089] In another embodiment of the present invention, Figure 1 As shown, the acoustic mesh assembly manufacturing equipment also includes a raw film discharge mechanism 140 and a raw film waste collection mechanism 150. The raw film discharge mechanism 140 is similar to other discharge structures, and the raw film waste collection mechanism 150 is similar to other waste collection mechanisms, and is implemented by a structure in which a motor drives the drum to rotate.

[0090] Furthermore, the original film unloading mechanism 140 and the original film waste collecting mechanism 150 are both installed on the frame 180 and are both located between the second rolling assembly 10b and the first cutting assembly 20a.

[0091] Furthermore, the original film unloading mechanism 140 is used to convey the original film and attach it to the surface of the single-sided adhesive layer 193 after passing through the first cutting assembly 20 a. The original film is adhered to the single-sided adhesive layer 193 .

[0092] Furthermore, the original film waste collection mechanism 150 is used to recycle the original film and remove the protective paper attached to the single-sided adhesive layer 193. When the original film waste collection mechanism 150 recycles the original film, it removes the protective paper attached to the single-sided adhesive layer 193. In other words, the single-sided adhesive layer 193 discharged by the single-sided adhesive discharge mechanism 30 is covered with protective paper. This protective paper protects the single-sided adhesive layer 193 and reduces contamination of the single-sided adhesive layer 193.

[0093] In another embodiment of the present invention, Figure 1 As shown, the manufacturing equipment of the acoustic mesh assembly further includes a single-sided adhesive outer frame waste collection mechanism 160, and the single-sided adhesive outer frame waste collection mechanism 160 is installed on the frame 180;

[0094] Furthermore, the single-sided adhesive outer frame waste collection mechanism 160 is used to recycle the outer frame of the single-sided adhesive layer 193 after passing through the second rolling assembly 10b. The outer frame of the single-sided adhesive layer 193 formed by cutting can be recycled through the single-sided adhesive outer frame waste collection mechanism 160.

[0095] In another embodiment of the present invention, Figure 1As shown, the acoustic mesh assembly manufacturing equipment further includes a bottom film waste collection mechanism 170, which is mounted at the output end of the frame 180 and is used to recycle the bottom film 191 attached to the lower surface of the blue film 194. The bottom film waste collection mechanism 170 finally recycles the bottom film 191 to form an acoustic mesh assembly 190 that is ready for shipment.

[0096] Specifically, combined Figures 4-5 As shown, the acoustic mesh assembly 190 produced by the acoustic mesh assembly manufacturing equipment includes a base film 191, a mesh 192, a single-sided adhesive layer 193, and a blue film 194. The mesh 192 is arranged on the base film 191. The single-sided adhesive layer 193 is provided with a perforation 1931 smaller in area than the mesh 192. The mesh 192 is bonded to the single-sided adhesive layer 193 and seals the perforation 1931. The single-sided adhesive layer 193 is bonded to the base film 191. The blue film 194 covers the base film 191, with the single-sided adhesive layer 193 positioned between the base film 191 and the blue film 194. The blue film 194 protects the single-sided adhesive layer 193. During the installation of the mesh 192, it prevents the single-sided adhesive layer 193 and the mesh 192 from being touched by foreign objects or contaminated by dust, thereby improving the reliability of the mesh 192.

[0097] When in use, first tear off the base film 191, then directly adhere the single-sided adhesive layer 193 to the product component, and align the mesh 192 to the predetermined position, and adhere it to the product component through the single-sided adhesive layer 193 to ensure that the position of the mesh 192 is fixed. In this way, since there is no need to directly adhere the mesh 192 to the product component, the size of the mesh 192 can be designed to be smaller, saving costs; in addition, the bonding to the product component is the single-sided adhesive layer 193 with a softer material, so that it is not easy to fall off after bonding, and the stability and effect of use are better.

[0098] Among them, such as Figure 4 The overlapping portion of the mesh 192 and the single-sided adhesive layer 193 is the portion where the mesh 192 and the single-sided adhesive layer 193 are bonded. Thus, the mesh 192 can be designed to be sufficiently small, as long as a portion of the mesh 192 can overlap and bond with the single-sided adhesive layer 193. The single-sided adhesive layer 193 is made of an inexpensive material, so a larger area can be designed without significantly increasing the cost. Furthermore, the stability of the product components bonded by the single-sided adhesive layer 193 is improved. The mesh 192 is positioned with the help of the single-sided adhesive layer 193, eliminating the need for directly applying glue or double-sided tape to the mesh 192, significantly reducing costs and improving product stability.

[0099] Furthermore, if Figures 4-5As shown, the mesh 192 and the perforations 1931 are both circular, and the radius of the mesh 192 is larger than the radius of the perforations 1931. Specifically, such a design can facilitate the processing of the mesh 192 and the perforations 1931. The regular circle is easier to process, and it is also easier to ensure the consistency of size. At the same time, when the mesh 192 is bonded to the single-sided adhesive layer 193, it is also easier to achieve centering. The center of the circular mesh 192 is aligned with the center of the circular perforations 1931. In this way, the area of ​​the mesh 192 bonded to the single-sided adhesive layer 193 and in contact with the peripheral portion of the single-sided adhesive layer 193 at the perforations 1931 is consistent. The connection stability of each part of the mesh 192 and the single-sided adhesive layer 193 is better and more balanced, and the effect is better.

[0100] Furthermore, the single-sided adhesive layer 193 is a black single-sided adhesive layer 193. The black single-sided adhesive layer 193 can achieve the effect of light shielding by utilizing color.

[0101] Furthermore, the thickness of the mesh 192 is between 0.01mm and 0.1mm; for example, the thickness of the mesh 192 can be 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm or 0.1mm. The mesh 192 of such thickness will not affect the penetration of sound due to being too thin, nor will it affect the sound quality due to being too thick.

[0102] Furthermore, the thickness of the single-sided adhesive layer 193 is between 0.1 mm and 0.2 mm. For example, the thickness of the single-sided adhesive layer 19330 can be 0.1 mm, 0.11 mm, 0.12 mm, 0.13 mm, 0.14 mm, 0.15 mm, 0.16 mm, 0.17 mm, 0.18 mm, 0.19 mm, or 0.2 mm. The single-sided adhesive layer 193 of such thickness will not be too thin, causing the mesh 192 to protrude from the single-sided adhesive layer 193, nor will it be too thick, occupying too much space and affecting the installation of other components or preventing further miniaturization of the product.

[0103] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
