[0002] A speaker is a transducer that converts electrical signals into sound signals. There are many types of speakers, including multimedia speakers, woofers, midrange speakers, tweeters, full-range speakers, etc., which are commonly used in multimedia home audio, cars, KTV venues, square broadcasts, computers, and various equipment and machines that need to produce sound.

[0003] Reference Figure 1 , for some types of speakers, it is necessary to stick a seal ring, such as an EVA (ethylene vinyl acetate copolymer) seal ring, on the edge of the back of the speaker chassis. Currently, the process of sticking the seal ring on the speaker is basically manual operation, that is, tear a seal ring, then take a speaker chassis and align the adhesive surface of the seal ring with the bonding surface of the speaker chassis. After the seal ring hole is aligned with the speaker chassis hole and pasted, then press it flat by hand. This operation method has low efficiency and is prone to misalignment, resulting in the adhesive surface of the seal ring not fully fitting with the edge of the speaker chassis. In the light case, it will cause poor appearance and requires rework; in the severe case, it will cause poor sealing during the subsequent assembly, air leakage during the packing of the box, and the hole positions are not aligned and prone to deviation, affecting the subsequent assembly and making it impossible to lock the screws.

[0024] The following will be described in detail through specific embodiments respectively.

[0025] Please refer to Figure 1 and Figure 2 , an embodiment of this application proposes a new type of tooling for attaching a sealing ring to a speaker (abbreviated as tooling), which can be used to quickly and accurately attach the sealing ring to the back edge area of the speaker chassis.

[0026] As Figure 1 and Figure 2 shown, the tooling of this application may include: a jig platform 10 and support columns 20 for supporting the jig platform 10. Among them, at least one mounting unit 100 is provided on the jig platform 10. The mounting unit 100 includes a sealing ring support edge 101 and a chassis positioning hole 102 surrounded by the sealing ring support edge 101. At least one corner of the sealing ring support edge 101 may be provided with a positioning post 103. Among them, the sealing ring support edge 101 is used to carry the sealing ring, the positioning post 103 is used to position the sealing ring, and the chassis positioning hole 102 is used to position the speaker chassis.

[0027] In some alternative embodiments, the jig platform 10 includes a plurality of mounting units 100 arranged in an array, such as Figure 1 the 2×4 = 8 shown in

[0028] In some alternative embodiments, the shape of the sealing ring support edge 101 can be determined according to the outer shape of the speaker chassis and the outer shape of the sealing ring. Exemplarily, its outer edge is generally rectangular and its inner edge is generally racetrack-shaped for application to rectangular speakers. And optionally, the corners of the outer edge can be arc-shaped.

[0029] In some alternative embodiments, the sealing ring support edge 101 includes two opposite long sides 101-1 and two opposite short sides 101-2.

[0030] In some alternative embodiments, a positioning post 103 is respectively arranged at four corners of the sealing ring support edge 101. Optionally, the positioning post 103 can be a metal positioning post, such as a copper positioning post. Optionally, the positioning post 103 can be embedded into the corner of the sealing ring support edge 101.

[0031] In some alternative embodiments, a support post 20 is respectively connected to four corners of the jig platform 10.

[0032] In some alternative embodiments, the jig platform 10 is threadedly connected to the support post 20.

[0033] In some alternative embodiments, the sealing ring support edge 101 surrounds and defines a basin frame positioning hole 102.

[0034] In some alternative embodiments, the jig platform 10 and the sealing ring support edge 101 can be an integrally formed structure. Exemplarily, it can be injection molded or cast molded or cut molded using a plastic material. For example, a flat hard material, such as a plastic plate or a metal plate, can be taken, and one or more holes are processed thereon as the basin frame positioning hole 102, and the area around the basin frame positioning hole 102 is used as the sealing ring support edge 101, thereby forming the jig platform 10.

[0035] In some alternative embodiments, the jig platform 10 and the mounting unit 100 can be structures that are independent, assembled, and detachable from each other. That is, the jig platform 10 and the sealing ring support edge 101 can be independent structures, and the sealing ring support edge 101 is installed on the jig platform 10 in an embedded manner, and the hollow area enclosed by the sealing ring support edge 101 serves as the basin frame positioning hole 102. In this way, the jig platform 10 can be matched to install the sealing ring support edges 101 of different sizes and shapes, and the sealing ring support edge 101 can be replaced, thereby improving applicability.

[0036] In some alternative embodiments, the support post 20 can be made of the same material or different materials as the jig platform 10. The material of the support post 20 can be plastic, such as polyoxymethylene (POM), etc., or can be metal, such as steel, copper, aluminum alloy, etc.

[0037] Reference Figure 3 , in some alternative embodiments, a structural schematic diagram of setting the sealing ring 30 on the jig platform 10 of the tooling of the present application and sleeving the speaker basin frame 40 is shown.

[0038] The new type of speaker sealing ring mounting tooling according to the embodiments of the present application, its use process may include:

[0039] (1) Use the support column 20 to support the fixture platform 10 and place it on the workbench surface, so that there is a certain height gap between the fixture platform 10 and the workbench surface.

[0040] (2) Place the side of the sealing ring with the release paper facing up and the other side facing down on the sealing ring support edge 101 of the fixture platform 10. Generally, positioning holes are provided on the sealing ring, and the positioning post 103 can be used for positioning during placement. When there are multiple mounting units 100 on the fixture platform 10, multiple sealing rings can be respectively placed corresponding to them. For example, 8 sealing rings are placed on the sealing ring support edges 101 of 8 mounting units 100. The shape of the sealing ring and the shape of the sealing ring support edge 101 can be basically the same.

[0041] (3) Tear off the release paper on the sealing ring to expose its sticky side;

[0042] (4) Place the back of the speaker frame facing down and the front facing up on the fixture platform 10. The back part of the speaker frame passes through the frame positioning hole 102 and is positioned by it. The raised part of the speaker frame enters the gap between the fixture platform 10 and the workbench surface. The edge area of the back of the speaker frame is stuck on the sealing ring support edge 101 around the frame positioning hole 102 and fits with the sticky side of the sealing ring. When there are multiple mounting units 100 on the fixture platform 10, multiple speaker frames can be placed in sequence and respectively fit with multiple sealing rings.

[0043] Among them, generally, positioning holes corresponding to the positioning posts can also be provided on the speaker frame for positioning.

[0044] (5) The speaker frame can be gently pressed by hand or a flat fixture to make its fit with the sealing ring more firm.

[0045] (6) Take out the speaker frame with the bonded sealing ring. Here, for example, the fixture platform 10 can be flipped 180 degrees, and then the speaker frame is pressed from the back to push the speaker frame out of the frame positioning hole 102 on the fixture platform 10.

[0046] So far, the process of pasting the sealing ring has completed the operation.

[0047] Next, the technical effects of this application will be described.

[0048] The existing manual pasting method has low operation efficiency, and the beat for one paste reaches 15S / PCS. Moreover, defects such as the sealing ring being pasted offset and blocking the installation hole, and the sealing ring being offset beyond the edge of the frame are likely to occur. These defects will affect the subsequent assembly and cause air leakage defects in the later stage. Exemplarily, the defective rate of pasting reaches 30%.

[0049] The advantages of the tooling of this application are reflected in:

[0050] 1. Multiple sealing rings can be pasted at one time, including: multiple sealing rings can be fixed on the jig platform first, and then multiple speaker frames can be sleeved and pasted in sequence, so as to reduce the cycle time of taking and pasting the sealing rings one by one and improve production efficiency; Experimental verification shows that when the tooling of the present application is provided with 8 mounting units 100, the operation time can be reduced to 55 seconds per 8, that is, 6.9 seconds / unit or less, which greatly improves the operation efficiency compared with the prior art.

[0051] 2. The present application locates the hole positions of the sealing rings through the jig platform. After aligning the hole positions of the frame, press the frame to make the sealing ring fit with the frame in place. This solution for pasting the sealing ring not only has a fast speed, but also has the advantages of accurate docking of hole positions and the sealing ring not deviating beyond the edge of the frame. It can improve the problems of the sealing ring deviating and blocking the hole, the sealing ring being pasted obliquely affecting the appearance, the subsequent assembly and air leakage. In addition to improving the operation efficiency, it can also improve the yield rate (for example, reducing the attachment defect rate to approach 0%), improve the product quality, make the product more consistent, and avoid the troubles caused to the subsequent process by the operation problems of this process.

[0052] As above, the technical solutions of the present application have been described in detail through specific embodiments. In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0053] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Those of ordinary skill in the art can modify the technical solutions recorded in the above embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and protection scope of the technical solutions of each embodiment of the present application.
