Description

Technical Field

[0001] This utility model belongs to the field of microphone dustproof mesh pasting technology, and in particular relates to a dustproof mesh pasting tool. Background Technology

[0002] Applying the microphone dust cover is a crucial manual assembly step. The operator first needs to clean the annular groove or flat surface on the microphone housing where the dust cover will be installed, ensuring it is free of dust and oil. Then, using precision tweezers, the operator carefully removes a pre-cut circular dust cover and aligns it precisely with the application point. After slowly peeling off the protective release paper from the back of the dust cover, the operator, with skillful technique and feel, smoothly places the dust cover into the groove and applies even, appropriate pressure to ensure a perfect fit to the housing, without any curling edges, wrinkles, or air bubbles. This step directly affects the product's appearance quality and long-term acoustic performance stability, as any imperfection can reduce the dust-proof effect or affect sound transmission. However, current manual operations are inefficient and struggle to guarantee consistent product quality.

[0003] To address the aforementioned issues, this application proposes a dustproof net pasting fixture. Utility Model Content

[0004] The purpose of this invention is to provide a dustproof net pasting fixture, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a dustproof net pasting fixture for pasting a dustproof net onto the small hole end of a microphone. The dustproof net comprises a non-woven fabric and an insulating sheet. The non-woven fabric has a pre-cut circular area corresponding to the microphone and several through holes. The pasting fixture includes a fixture base, on which a positioning base is fixed for placing the dustproof net. An pasting plate that fits into the positioning base is placed on the dustproof net. The pasting plate has pasting holes corresponding to the circular area of ​​the dustproof net. A sieve tray is stacked on the pasting plate, and the sieve tray has sieve holes corresponding to the pasting holes. The positioning base has a pasting positioning post with a corresponding through hole. The pasting plate and the sieve tray respectively have a first positioning hole and a second positioning hole corresponding to the pasting positioning post.

[0007] Furthermore, a retaining ring is formed on the top of the sieve disc.

[0008] Furthermore, a raised plate is fixed on the tooling base, a demolding base is fixed on the raised plate, a through demolding hole is opened on the demolding base, a demolding template is provided above the demolding base, and demolding ejector pins are fixed on the demolding template for demolding the microphone on the adhesive plate.

[0009] Furthermore, the demolding base is fixed with tooling positioning posts corresponding to the first positioning hole and through hole.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figures 1-5As shown, this utility model is a dustproof net pasting tool, used to paste the dustproof net 3 to the small hole end of the microphone. The dustproof net 3 includes a non-woven fabric 31 and an isolation sheet 32. The non-woven fabric 31 and the isolation sheet 32 ​​are bonded together by double-sided adhesive. The isolation sheet 32 ​​can be peeled off independently from the double-sided adhesive. At this time, the double-sided adhesive on the non-woven fabric 31 plays a connecting role when pasting with the microphone. The non-woven fabric 31 has a pre-cut circular area corresponding to the microphone, and several through holes 33 are opened on the non-woven fabric 31.

[0029] A dustproof net pasting fixture includes a fixture base 1, a positioning base 2 fixed on the fixture base 1 for placing the dustproof net 3, an pasting plate 4 that fits into the positioning base 2 placed on the dustproof net 3, pasting holes 41 corresponding to the circular areas of the dustproof net 3 being opened through the pasting plate 4, a sieve tray 5 stacked on the pasting plate 4, and sieve holes 51 corresponding to the pasting holes 41 being opened through the sieve tray 5; a pasting positioning post 21 corresponding to a through hole 33 is fixed on the positioning base 2, and a first positioning hole 42 and a second positioning hole 52 respectively are opened on the pasting plate 4 and the sieve tray 5 to paste the positioning post 21.

[0030] Furthermore, such as Figures 1-3 As shown, a retaining ring is formed on the top of the sieve plate 5 to prevent the microphone from falling off during the arrangement of the microphone into the sieve holes 51.

[0031] Furthermore, such as Figures 1-2 As shown, in order to prevent the microphones from entering the adhesive holes 41 during arrangement and to avoid multiple microphones from stacking, the isolation sheet 32 ​​is torn off from the non-woven fabric 31 and placed between the adhesive plate 4 and the sieve tray 5. At this time, the microphones are located in the sieve holes 51. After the microphones are neatly arranged on the sieve tray 5, the excess microphones are removed, and then the isolation sheet 32 ​​is pulled out, so that the microphones can be placed one by one in the adhesive holes 41.

[0032] Furthermore, such as Figure 1 , Figure 2 As shown, a raised plate 11 is also fixed on the tooling base 1, and a demolding base 6 is fixed on the raised plate 11. A through demolding hole 61 is opened on the demolding base 6, and a demolding template 9 is provided above the demolding base 6. A demolding ejector pin 91 is fixed on the demolding template 9 for demolding the microphone on the adhesive plate 4.

[0033] Furthermore, such as Figure 1 and Figure 3 As shown, the demolding base 6 is fixed with a tooling positioning post 62 corresponding to the first positioning hole 42 and the through hole 33. The tooling positioning post 62 and the first positioning hole 42 and the through hole 33 are used to precisely align the pasting hole 41 on the pasting plate 4 with the demolding hole 61 on the demolding base 6, thereby facilitating the accurate demolding of the microphone.

[0034] Furthermore, such as Figure 1 , Figure 5As shown, a reinforcing plate 8 is fixed at the lower end of the demolding template 9. The reinforcing plate 8 has a demolding support hole 81 corresponding to the demolding ejector pin 91. By passing the demolding ejector pin 91 through the demolding support hole 81, the support hole 81 can enhance the connection reliability between the demolding ejector pin 91 and the demolding template 9 in the radial range and prevent the demolding ejector pin 91 from tilting or bending.

[0035] Furthermore, such as Figure 1 , Figure 5 As shown, a demolding base 6 has a demolding positioning hole 63. A demolding positioning post 82 is fixed at the lower end of the reinforcing plate 8, corresponding to the demolding positioning hole 63. Through the cooperation between the demolding positioning hole 63 and the demolding positioning post 82, the adhesive plate 4 can be guided on the demolding base 6 before the demolding ejector pin 91 contacts the dustproof net 3, ensuring the precise docking of the demolding ejector pin 91 and the adhesive hole 41 during demolding.

[0036] Furthermore, such as Figures 1-2 As shown, a receiving box 7 is placed on the tooling base 1, located directly below the demolding base 6; specifically, the receiving box 7 is located directly below the demolding hole 61 on the demolding base 6, and is used to collect the pasted microphones.

[0037] Furthermore, in order to facilitate the individual handling of the adhesive board 4 and the flipping of it when carrying the dustproof net 3 and the microphone, the adhesive board 4 is provided with a handle 43.

[0038] In one specific application of this embodiment, the positioning base 2, the shim plate 11, and the demolding base 6 are fixedly installed on the tooling base 1, the reinforcing plate 8 is fixed on the demolding template 9, the demolding template 9 is fixed on the pressing machine, and the receiving box 7 is placed on the tooling base 1 directly below the demolding base 6.

[0039] The steps for pasting once are as follows:

[0040] S1. The non-woven fabric 31 is fitted onto the outside of the adhesive positioning post 21 through the through hole 33 and is tightly attached to the positioning base 2. The isolation sheet 32 ​​is peeled off, the first positioning hole 42 is fitted onto the outside of the adhesive positioning post 21, and the bottom of the adhesive plate 4 is attached to the top surface of the non-woven fabric 31.

[0041] S2. The removed isolation sheet 32 ​​covers the adhesive hole 41 from above the adhesive plate 4. The sieve 5 is placed above the adhesive plate 4 through the second positioning hole 52 and the adhesive positioning post 21. The microphone hole is placed downwards into the sieve hole 51.

[0042] S3. After removing the isolation sheet 32, the microphones in the sieve holes 51 are all put into the adhesive holes 41. Take out the sieve plate 5, use the pressure plate to press the microphones, and stick the microphones to the dustproof mesh 3.

[0043] S4. Use the handle 43 on the adhesive board 4 to remove the dustproof net 3 and the microphone from the positioning base 2, then flip them over so that the microphone is facing down and the dustproof net 3 is facing up. At this time, the microphone will not fall off due to the double-sided adhesive on the dustproof net 3.

[0044] S5. The adhesive plate 4 is placed on the demolding base 6. The adhesive hole 41 and the non-woven fabric 31 are inserted into the outside of the tooling positioning post 62. Then the part of the microphone protruding from the adhesive hole 41 will enter the demolding hole 61.

[0045] S6. Start the pressing machine to move the reinforcing plate 8 and the demolding plate 9 downward. The demolding positioning pin 82 enters the demolding positioning hole 63. The demolding ejector pin 91 presses down the part of the dustproof net 3 that is pasted with the microphone. 93 enters the pasting hole 41, thereby collecting the microphone pasted with the dustproof net 3 in the pasting hole 41 into the demolding base 6.

[0046] S7. The pressing machine moves the reinforcing plate 8 and the template 9 upwards, and peels off the remaining dustproof netting 3 on the adhesive plate 4.
