Description

Technical Field

[0001] The invention belongs to the technical field of acoustic meshes, and in particular relates to an acoustic mesh assembly and a manufacturing process thereof. 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 set on the mesh, and then the mesh is bonded to the corresponding product component through glue or double-sided tape. In order to ensure that the mesh can be effectively bonded to the product component 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 product component, so as to improve the stability and reliability of the bonding. However, the material cost of the mesh is relatively high. Although designing it to be larger can improve the stability of the connection with the product component, the production cost is greatly increased; and the mesh material is relatively hard, and it is easy to fall off the product component as the use time increases. Summary of the invention

[0003] The purpose of the present invention is to provide a manufacturing process for an acoustic mesh assembly, aiming to solve the technical problems of high production cost and easy falling off of the acoustic mesh in the prior art.

[0017] The above one or more technical solutions in the manufacturing process of the acoustic mesh assembly provided by the embodiment of the present invention have at least one of the following technical effects: when using the acoustic mesh assembly produced by the manufacturing process provided by the embodiment of the present invention, the base film is first torn off, and then the single-sided adhesive layer is directly bonded to the component of the product, and the mesh is aligned to the predetermined position, and is bonded to the component of the product through the single-sided adhesive layer to ensure that the position of the mesh is fixed. In this way, since there is no need to directly bond the mesh to the component of the product, the size of the mesh can be designed to be smaller, saving costs.

[0024] Optionally, the thickness of the mesh is between 0.01 mm and 0.1 mm;

Figures 1 to 4 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, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0041] In one embodiment of the present invention, Figures 1 to 3 As shown, a process for manufacturing an acoustic mesh assembly is provided, comprising the following steps:

[0042] S10: providing a bottom film 10; the bottom film 10 plays a role of bottom protection, ensuring that the produced components can be protected during transportation or sealing;

[0043] S20: providing a mesh 20, and setting the mesh 20 on the base film 10; the mesh 20 does not need to be provided with double-sided tape or glue, so the mesh 20 can be designed to be as small as possible to meet the use requirements, which can greatly save the required materials and reduce the manufacturing cost; further, a plurality of meshes 20 can be placed on the base film 10;

[0044] S30: providing a single-sided adhesive layer 30, and providing a perforation 31 with an area smaller than that of the mesh 20 on the single-sided adhesive layer 30; this ensures that the mesh 20 will not slip out of the perforation 31, that is, when the mesh 20 is arranged opposite to the perforation 31, a part of the structure will overlap with the single-sided adhesive layer 30; the number of the single-sided adhesive layer 30 is the same as the number of the mesh 20;

[0045] S40: bonding the mesh 20 to the single-sided adhesive layer 30, and making the mesh 20 seal the perforations 31; the single-sided adhesive layer 30 is used to bond the mesh 20, and the mesh 20 correspondingly seals the perforations 31 to ensure that the mesh 20 can allow sound to penetrate normally after installation;

[0046] S50: Bond the single-sided adhesive layer 30 to the base film 10, and make the mesh 20 located between the base film 10 and the single-sided adhesive layer 30; the single-sided adhesive layer 30 confines the mesh 20 between it and the base film 10 to form the entire acoustic mesh assembly, which can protect the mesh 20.

[0047] Specifically, when using the acoustic mesh assembly produced by the manufacturing process provided by the embodiment of the present invention, the base film 10 is torn off first, and then the single-sided adhesive layer 30 is directly bonded to the product component, and the mesh 20 is aligned to a predetermined position, and is bonded to the product component through the single-sided adhesive layer 30 to ensure that the position of the mesh 20 is fixed. In this way, since there is no need to directly bond the mesh 20 to the product component, the size of the mesh 20 can be designed to be smaller, thereby saving costs. In addition, the bonding with the product component is the single-sided adhesive layer 30 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.

[0048] Furthermore, if Figures 1 to 3 As shown, in the step S20, the mesh 20 provided is circular; in the step S30, a circular perforation 31 is opened on the single-sided adhesive layer 30, and it is ensured that the radius of the perforation 31 is smaller than the radius of the mesh 20. Specifically, such a design can facilitate the processing of the mesh 20 and the perforation 31, and 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 20 is bonded to the single-sided adhesive layer 30, it is also easier to achieve centering, and the center of the circular mesh 20 is aligned with the center of the circular perforation 31, so that the area of ​​the mesh 20 bonded to the single-sided adhesive layer 30 and the contact area of ​​the single-sided adhesive layer 30 at the peripheral part of the perforation 31 is consistent, and the connection stability of each part of the mesh 20 and the single-sided adhesive layer 30 is better and more balanced, and the effect is better.

[0049] Furthermore, in the step S30, the single-sided adhesive layer 30 provided is a black single-sided adhesive layer 30. The black single-sided adhesive layer 30 can achieve the effect of light shielding by using color.

[0050] Furthermore, in the step S20, the thickness of the mesh 20 provided is between 0.01 mm and 0.1 mm; for example, the thickness of the mesh 20 can be 0.01 mm, 0.02 mm, 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm, 0.09 mm or 0.1 mm. The mesh 20 of such thickness will not affect the sound penetration due to being too thin, nor will it affect the sound quality due to being too thick.

[0051] Further, in the step S30, the thickness of the single-sided adhesive layer 30 provided is between 0.1 mm and 0.2 mm. For example, the thickness of the single-sided adhesive layer 30 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 30 of such thickness will not cause the mesh 20 to protrude on the single-sided adhesive layer 30 due to being too thin, nor will it occupy too much space due to being too thick, affecting the installation of other components or causing the product to be unable to be further miniaturized.

[0052] Furthermore, if Figures 1 to 3 As shown, the manufacturing process of the acoustic mesh assembly further includes step S60: providing a blue film 40, covering the blue film 40 on the base film 10, and positioning the single-sided adhesive layer 30 between the base film 10 and the blue film 40. The blue film 40 can protect the single-sided adhesive layer 30, and prevent the single-sided adhesive layer 30 and the mesh 20 from being touched by foreign objects or contaminated by dust before installing the mesh 20, thereby improving the reliability of the mesh 20.

[0053] like Figure 3~4 As shown, after the acoustic mesh assembly is manufactured, it is necessary to further perform a quality inspection step S70 on the acoustic mesh assembly. Specifically, the quality inspection specifically includes:

[0054] S71: placing the acoustic mesh assembly on a test bench, and performing a mesh leakage inspection on the acoustic mesh assembly under a lighting fixture;

[0055] S72: After completing the mesh leakage inspection of the acoustic mesh assembly, continue to perform a hole blocking inspection on the acoustic mesh assembly located on the inspection table;

[0056] S73: After completing the hole blocking inspection of the acoustic mesh assembly, the acoustic mesh assembly is photographed using a CCD, and the instant photograph of the acoustic mesh assembly is compared with a preset photograph to perform a hole deviation inspection on the acoustic mesh assembly;

[0057] S74: After completing the hole deviation inspection of the acoustic mesh assembly, perform a thickness inspection on the acoustic mesh assembly.

[0058] Through such inspection steps, it can be ensured that the acoustic mesh components produced are qualified products before shipment, thereby ensuring the quality of the products.

[0059] Furthermore, in step S71, the illumination of the lighting fixture is within the range of 80-120 LUX. Specifically, when the illumination is within the range of 80-120 LUX, effective mesh leakage inspection can be achieved, avoiding inspection effects caused by too dark or too bright brightness.

[0060] Furthermore, in step S71, the lighting fixture is a light box, which is easy to obtain and reduces the inspection conditions; the acoustic mesh assembly is placed on the light box, and the acoustic mesh assembly is inspected for mesh leakage through the light transmission of the light box. In this way, the acoustic mesh assembly can be effectively inspected for mesh leakage through the light transmitted by the light box.

[0061] Furthermore, the hole deviation check in step S73 is to check the concentricity deviation between the center of the mesh 20 of the acoustic mesh assembly and the center of the perforation 31. This ensures that the position where the mesh 20 is bonded to the single layer of adhesive is always at the set position, thereby improving the quality of the product.

[0062] Furthermore, in step S74, the thickness check is: using a thickness gauge to clamp the acoustic mesh assembly, measuring whether the thickness of the acoustic mesh assembly meets the requirements, and if the thickness of the acoustic mesh 20 exceeds the specification, it is picked out. Through the thickness inspection, the mesh assembly that exceeds the thickness range can be picked out to avoid affecting the subsequent use of the product due to thickness problems.

[0063] like Figure 1~2 As shown, another embodiment of the present invention provides an acoustic mesh assembly, comprising a base film 10, a mesh 20 and a single-sided adhesive layer 30, wherein the mesh 20 is arranged on the base film 10. The single-sided adhesive layer 30 is provided with a perforation 31 whose area is smaller than that of the mesh 20, and the mesh 20 is bonded to the single-sided adhesive layer 30 and seals the perforation 31, and the single-sided adhesive layer 30 is bonded to the base film 10. When in use, the base film 10 is first torn open, and then the single-sided adhesive layer 30 is directly bonded to the product component, and the mesh 20 is aligned to a predetermined position, and the single-sided adhesive layer 30 is bonded to the product component to ensure that the position of the mesh 20 is fixed. In this way, since the mesh 20 does not need to be directly bonded to the product component, the size of the mesh 20 can be designed to be smaller, saving costs; in addition, the bonding with the product component is the single-sided adhesive layer 30 with a softer material, so that it is not easy to fall off after bonding, and the stability and effect of use are better.

[0064] Among them, Figure 1 The overlapping part of the mesh 20 and the single-sided adhesive layer 30 is the part where the mesh 20 and the single-sided adhesive layer 30 are bonded. In this way, the mesh 20 can be designed to be small enough, as long as a part that can overlap with the single-sided adhesive layer 30 is kept for bonding. The single-sided adhesive layer 30 is a cheap material, and a larger area will not increase the cost too much. In addition, the stability of the product parts bonded by the single-sided adhesive layer 30 is better. The mesh 20 is positioned by the single-sided adhesive layer 30, eliminating the step of directly setting glue or double-sided adhesive on the mesh 20, greatly reducing the cost and improving the stability of product use.

[0065] Furthermore, if Figure 1~2 As shown, the mesh 20 and the perforation 31 are both circular, and the radius of the mesh 20 is greater than the radius of the perforation 31. Specifically, such a design can facilitate the processing of the mesh 20 and the perforation 31. 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 20 is bonded to the single-sided adhesive layer 30, it is also easier to achieve centering, aligning the center of the circular mesh 20 with the center of the circular perforation 31, so that the area of ​​the mesh 20 bonded to the single-sided adhesive layer 30 and the contact area of ​​the single-sided adhesive layer 30 at the peripheral part of the perforation 31 are consistent, and the connection stability of each part of the mesh 20 and the single-sided adhesive layer 30 is better and more balanced, and the effect is better.

[0066] Furthermore, the single-sided adhesive layer 30 is a black single-sided adhesive layer 30. The black single-sided adhesive layer 30 can achieve the effect of light shielding by using color.

[0067] Furthermore, the thickness of the mesh 20 is between 0.01mm and 0.1mm; for example, the thickness of the mesh 20 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 20 of such thickness will not affect the sound penetration due to being too thin, nor will it affect the sound quality due to being too thick.

[0068] Further, the thickness of the single-sided adhesive layer 30 is between 0.1 mm and 0.2 mm. For example, the thickness of the single-sided adhesive layer 30 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 30 of such thickness will not cause the mesh 20 to protrude on the single-sided adhesive layer 30 due to being too thin, nor will it occupy too much space due to being too thick, affecting the installation of other components or causing the product to be unable to be further miniaturized.

[0069] Furthermore, if Figure 1~2 As shown, the acoustic mesh assembly further includes a blue film 40, which covers the base film 10 and allows the single-sided adhesive layer 30 to be located between the base film 10 and the blue film 40. The blue film 40 can protect the single-sided adhesive layer 30, and when the mesh 20 is installed, the single-sided adhesive layer 30 and the mesh 20 are prevented from being touched by foreign objects or contaminated by dust, thereby improving the reliability of the mesh 20.

[0070] 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 protection scope of the present invention.
