In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0046] like Figure 1 and Figure 2 As shown, this embodiment provides an assembly jig 100 for fitting and fixing the speaker mesh 200 on the product 300, thereby improving the listening quality of the speaker. By using the assembly jig 100 to fit and fix the speaker mesh 200 on the product 300, manpower is liberated and work efficiency is improved.

[0047] Specifically, if Figure 1 and Figure 2 As shown, the assembly jig 100 mainly includes a supporting component 6, a product carrying component 1, a mesh positioning component 2 and a heating component 4, wherein the product carrying component 1, the mesh positioning component 2 and the heating component 4 are all arranged on the supporting component 6, the product carrying component 1 is used to carry the product 300, the mesh positioning component 2 is used to adsorb and fix the speaker mesh 200, and the mesh positioning component 2 is located below the product 300, the heating component 4 and the mesh positioning component 2 are respectively located on both sides of the front-to-back direction of the inner wall of the product 300 to be bonded, the heating component 4 and the mesh positioning component 2 can move toward each other along the front-to-back direction, so that when the heating component 4 heats the inner wall of the product 300 to be bonded, the mesh positioning component 2 drives the speaker mesh 200 to be bonded to the inner wall of the product 300 to be bonded, thereby realizing the thermal bonding and fixation of the speaker mesh 200 at the product 300 to be bonded position, and ensuring the firm bonding of the speaker mesh 200 at the to-be-bonded position.

[0048] It should be noted that a product 300 has multiple locations to be attached, and multiple speaker mesh films 200 need to be attached. In this embodiment, in order to improve the working efficiency of the assembly jig 100, as shown in FIG. Figure 2 As shown, a plurality of mesh positioning components 2 are arranged at intervals along the left-right direction, and each mesh positioning component 2 can position a speaker mesh 200. A plurality of mesh positioning components 2 can simultaneously move toward the direction of the to-be-bonded position close to the inner wall of the product 300, so as to achieve the attachment of the corresponding speaker mesh 200, so that the assembly jig 100 can synchronously bond the plurality of speaker meshes 200 to the to-be-bonded position of the product 300, thereby greatly improving the bonding efficiency of the assembly jig 100.

[0049] In this embodiment, the support assembly 6 includes a support seat 61 and a support plate 62, wherein the support plate 62 is fixed on the support seat 61, the product carrying assembly 1 is fixed on the support plate 62, and the mesh positioning assembly 2 and the heating assembly 4 are both arranged on the support plate 62. By providing the support seat 61, the stability and reliability of the placement of the entire assembly jig 100 are guaranteed.

[0050] Combination Figure 1 and Figure 2 The specific structure of the product carrying component 1 is described as follows: Figure 1 and Figure 2 As shown, the product bearing assembly 1 includes a plurality of bearing platforms 11 arranged at intervals, and the plurality of bearing platforms 11 are fixed at intervals on the support plate 62, and the plurality of bearing platforms 11 jointly bear the product 300, thereby achieving a stable support for the product 300. It should be noted that the bearing surface of the bearing platform 11 bearing the product 300 is higher than the retina positioning assembly 2, thereby ensuring that the retina positioning assembly 2 adsorbs the speaker retina 200 between the support plate 62 and the product 300, and ensuring that the retina positioning assembly 2 drives the speaker retina 200 to move under the product 300 to fit the speaker retina 200 to the position to be fitted on the inner wall of the product 300. In addition, by designing the product bearing assembly 1 in the form of a plurality of bearing platforms 11 arranged at intervals on the support plate 62, the setting of the retina positioning assembly 2 on the support plate 62 is avoided, making the structure of the whole machine more compact.

[0051] Combination Figure 1 and Figure 2 The specific structure of the heating component 4 is described as follows: Figure 1 and Figure 2 As shown, the heating assembly 4 includes a heating element 41 and a second driving element 42, wherein the heating element 41 is used to heat the position to be bonded on the inner wall of the product 300, the second driving element 42 is arranged on the support plate 62, and the output end of the second driving element 42 is connected to the heating element 41, and the second driving element 42 is used to drive the heating element 41 to move in the front-to-back direction relative to the support plate 62, so as to ensure that the heating element 41 is bonded to the position to be bonded of the product 300, and the heating of the position to be bonded is realized. Specifically, the second driving element 42 provided in this embodiment can be a linear cylinder or a linear motor. This embodiment does not specifically limit the specific form of the second driving element 42, as long as it can drive the heating element 41 to move in the front-to-back direction relative to the support plate 62.

[0052] In this embodiment, the heating element 41 includes a connecting block 411 and a heating block 412, wherein the output end of the second driving element 42 is connected to the connecting block 411, and the heating block 412 is connected to the connecting block 411, and the second driving element 42 drives the heating block 412 to heat the position to be bonded of the product 300 through the connecting block 411. Preferably, the heating block 412 can be a heating copper block, which has the advantages of good heating effect and low cost.

[0053] In order to ensure that the heating element 41 moves more smoothly relative to the support plate 62, as shown in FIG. Figure 3 As shown, the heating assembly 4 provided in this embodiment also includes a guide member 43, which is used to guide the heating member 41 to move relative to the support plate 62 in the front-to-back direction to prevent the heating member 41 from being offset during the movement, thereby ensuring that the heating block 412 can be more accurately and stably fitted with the position to be fitted with the product 300. Specifically, the guide member 43 provided in this embodiment includes a first guide rail 431 and a first slider 432 that are slidably connected, the first guide rail 431 extends in the front-to-back direction, the first guide rail 431 is fixed on the support plate 62, and the first slider 432 is fixed on the connection block 411. By designing the guide member 43 as a guide rail slider, the structure is simple and more reliable.

[0054] It should be noted that since the speaker mesh 200 is L-shaped, including two connected side walls, and the speaker mesh 200 is thin, the speaker mesh 200 is prone to warping on the mesh positioning component 2 during the bonding process, thereby reducing the flatness of the speaker mesh 200 on the product 300, thereby reducing the yield of the product 300.

[0055] In order to solve the above problems, Figure 2 , Figure 4 and Figure 5 As shown, the membrane positioning component 2 provided in this embodiment is used to adsorb and fix the two side walls of the speaker membrane 200, avoiding the problem of warping of the speaker membrane 200 during the bonding process, so that the speaker membrane 200 is more flatly adsorbed and fixed on the membrane positioning component 2, thereby improving the stability of the speaker membrane 200 on the membrane positioning component 2, ensuring that the speaker membrane 200 is more flatly bonded and fixed at the position to be bonded of the product 300, and improving the yield of the product 300.

[0056] Specifically, if Figure 2 , Figure 4 and Figure 5As shown, the reticular membrane positioning assembly 2 includes a positioning member 21, a vacuum generator and a first driving member 22, wherein the top and side of the positioning member 21 are provided with vacuum adsorption holes 2111 connected to the vacuum generator, the top of the positioning member 21 is used to support one side wall of the speaker reticular membrane 200, the side of the positioning member 21 is in contact with the other side wall of the speaker reticular membrane 200, the first driving member 22 is arranged on the supporting plate 62, the output end of the first driving member 22 is connected to the positioning member 21, and the first driving member 22 can drive the positioning member 21 toward the direction close to the inner wall of the product 300 ( Figure 2 The speaker mesh 200 moves in the forward direction. By adsorbing the two side walls of the speaker mesh 200 on the side and top of the positioning member 21 respectively, the speaker mesh 200 is prevented from warping from the top of the positioning member 21, thereby ensuring the flatness of the speaker mesh 200 on the positioning member 21. It should be noted that when the positioning member 21 is required to drive the speaker mesh 200 to fit to the position to be bonded of the product 300, the vacuum generator draws vacuum on each vacuum adsorption hole 2111, thereby ensuring the adsorption and fixation of the speaker mesh 200 on the positioning member 21, and then the first driving member 22 drives the positioning member 21 to move forward to ensure that the speaker mesh 200 is bonded to the position to be bonded of the product 300. At this time, the vacuum generator removes the vacuum suction, and then the first driving member 22 drives the positioning member 21 to move backward to complete the bonding process, which is also convenient for the bonding operation of the next product 300. Specifically, the first driving member 22 may be a linear cylinder or a linear motor. The present embodiment does not specifically limit the specific form of the first driving member 22 .

[0057] In order to improve the fitting accuracy of the assembly jig 100, as Figure 2 and Figure 5 As shown, the retina positioning assembly 2 also includes a guide member 23, which is used to guide the positioning member 21 to move in the front-to-back direction to avoid the positioning member 21 from deviating and shaking in the left-to-right direction during the movement, thereby ensuring the stability and accuracy of the positioning member 21 during the movement.

[0058] Specifically, the positioning member 21 includes a positioning plate 211 and a connecting plate 212 connected to each other, wherein the connecting plate 212 is connected to the output end of the first driving member 22, the top and side of the positioning plate 211 are provided with vacuum adsorption holes 2111, and the guide member 23 includes a guiding block 231, the guiding block 231 is fixed on the support plate 62, the guiding block 231 is located below the positioning plate 211, and a guiding groove 2311 is provided on the guiding block 231, and the positioning plate 211 can move along the guiding groove 2311. By providing the guiding groove 2311, and the shape of the guiding groove 2311 is adapted to the outer contour of the positioning plate 211, the positioning plate 211 is prevented from deflecting and shaking during the movement in the front-rear direction, thereby ensuring the fitting accuracy of the positioning plate 211 to the speaker mesh 200. In addition, the guide block 231 has a certain supporting effect on the positioning plate 211 below the positioning plate 211, and the guide block 231 has the advantages of simple structure and easy processing.

[0059] In addition, the guide member 23 also includes a second guide rail 232 and a second slider 233 that are slidably connected, wherein the second guide rail 232 is fixed on the support plate 62, the second guide rail 232 extends along the front-to-back direction, and the second slider 233 is fixed on the connecting plate 212. By setting the second guide rail 232 and the second slider 233, a guiding effect is provided for the movement of the connecting plate 212 along the front-to-back direction, thereby further improving the stability and accuracy of the movement of the positioning member 21 along the front-to-back direction.

[0060] In addition, if Figure 3 As shown, the assembly jig 100 provided in this embodiment also includes a product positioning component 3, which is used to block and position the product 300 on the product supporting component 1, thereby ensuring the precise positioning of the product 300 on the product supporting component 1 and ensuring the fitting accuracy between the product 300 and the speaker mesh membrane 200.

[0061] Specifically, the product positioning assembly 3 includes a first positioning block 31 and a clamping push block 32, wherein the first positioning block 31 and the clamping push block 32 are respectively located on both sides of the product 300 along the left and right directions, the first positioning block 31 is fixed on the support plate 62, the clamping push block 32 is arranged on the support plate 62, and the clamping push block 32 can move toward the direction of the first positioning block 31, thereby ensuring that the first positioning block 31 and the clamping push block 32 are respectively clamped on both sides of the product 300 along the left and right directions, thereby realizing accurate positioning of the product 300 on the product carrying assembly 1. Preferably, in this embodiment, two groups of first positioning blocks 31 are provided, and the two groups of first positioning blocks 31 are arranged at intervals along the front and rear directions on the support plate 62, and each first positioning block 31 is correspondingly provided with a clamping push block 32, thereby ensuring the reliability of positioning the product 300 along the left and right directions. It should be noted that in other embodiments, three or even more groups of first positioning blocks 31 can be provided, and the number of first positioning blocks 31 can be set according to needs.

[0062] In this embodiment, if Figure 3 As shown, the clamping push block 32 includes a push block body 321 and a push block driving member 322, wherein the push block driving member 322 is disposed on the support plate 62, and the output end of the push block driving member 322 is connected to the push block body 321, and the push block driving member 322 can drive the push block body 321 to move toward the first positioning block 31, so that the push block body 321 and the first positioning block 31 are respectively clamped on both sides of the product 300 along the left and right directions. Specifically, the push block driving member 322 can be a linear cylinder or a linear motor, and the specific form of the push block driving member 322 is not specifically limited in this embodiment.

[0063] Furthermore, if Figure 3 As shown, the product positioning assembly 3 also includes a second positioning block 33, which is arranged opposite to the heating assembly 4 and is located at the rear side of the product 300. The second positioning block 33 is fixed on the support plate 62. When the second driving member 42 drives the heating member 41 to move relative to the support plate 62 toward the second positioning block 33, the second positioning block 33 abuts against the rear side of the product 300, thereby limiting the product 300 along the front and rear directions, and realizing accurate positioning of the product 300 on the product supporting assembly 1.

[0064] In order to ensure the stability of product 300 during the bonding process, Figure 3As shown, the assembly jig 100 provided in this embodiment also includes a pressing component 5, which is arranged on the connecting block 411. The pressing component 5 is located above the product 300. The pressing component 5 can press the product 300 down and fix it on the product carrying component 1. The pressing component 5 and the product carrying component 1 jointly clamp and fix the product 300 in the up and down directions, ensuring that the product 300 is firmly fixed. It should be noted that since the pressing component 5 is arranged on the connecting block 411, the second driving member 42 can synchronously drive the heating member 41 and the pressing component 5 to move in the front-to-back direction, thereby ensuring that the pressing component 5 can be accurately pressed against the product 300.
