Description

Technical Field

[0001] This utility model relates to the field of speaker assembly technology, and in particular to a jig for assembling a drum paper spring wave ring. Background Technology

[0002] With the continuous development of audio technology, the speaker, as the output terminal of audio equipment, mainly converts electrical signals into sound through loudspeakers. Relying on the sound-enhancing effect of the speaker, it can reproduce the live effect as much as possible. It is widely used in home theater systems, background music systems, multimedia audio systems, public address systems and other fields. The speaker usually includes a cabinet, PCB board, speaker unit and grille. The speaker unit is set in the cabinet, and its sound output end faces the grille so that the sound of the speaker unit is played outward through the grille. The speaker unit includes components such as spring, diaphragm, bracket, magnet, voice coil and so on.

[0003] The existing assembly process for the spring, diaphragm, and voice coil is carried out separately. First, the diaphragm and spring are manually glued and assembled. After the glue has solidified, the voice coil is then glued to the diaphragm. Because the diaphragm and spring are glued together first, they may undergo slight deformation or stress during the curing process. This makes it difficult to accurately align the center axis of the voice coil with the ideal center axis of the magnetic gap when the voice coil is glued later. This can easily cause the voice coil to become misaligned, resulting in unstable operation of the speaker unit. Consequently, the product yield rate decreases, failing to meet user needs and limiting its applicability.

[0004] Therefore, it is necessary to research a new technical solution to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a drum paper, spring, and voice coil assembly fixture. This fixture utilizes a drum paper placed in a first recess and glued, followed by placing the spring on the drum paper, then mounting the voice coil on the connecting post, and finally assembling the upper mold base onto the lower mold base. This achieves simultaneous, one-time bonding and positioning of the drum paper, spring, and voice coil. In particular, the positioning groove and wire groove facilitate the placement and positioning of the leads of the drum paper, spring, and voice coil on the lower mold base and upper mold base, respectively, thus aiding in subsequent bonding and fixing operations. This improves the bonding effect of the components and the product yield, and has a wide range of applications.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A jig for assembling a voice coil and a spring coil includes an upper mold base and a lower mold base that are connected and assembled together. The lower end of the upper mold base is provided with a connecting post for positioning the voice coil and a wire groove for positioning the voice coil lead wire. The outer end of the wire groove passes through the upper mold base and is provided with a wire outlet. The upper end of the lower mold base is provided with a first recess for positioning the voice coil. One side of the first recess is provided with a positioning groove to match and position the extension of the voice coil and the spring coil.

[0008] As a preferred embodiment, the lower mold base has an upwardly extending limiting portion, the limiting portion having several portions arranged at intervals around the edge of the first recess, the inner wall of the limiting portion contacting and limiting the outer wall of the drum paper and the outer wall of the spring wave, and the positioning groove being disposed on any of the limiting portions.

[0009] As a preferred embodiment, the upper mold base is provided with a foolproof part on its edge, and the upper edge of the lower mold base is provided with a foolproof groove that matches and positions the foolproof part. The foolproof part is adapted to the foolproof groove to realize the positioning and assembly between the upper mold base and the lower mold base.

[0010] As a preferred embodiment, the upper end of the lower mold base is further provided with a second recess for contacting and assembling with the upper mold base. The first recess is located at the center of the second recess, and the anti-fooling groove is located on one side of the edge of the second recess and is correspondingly provided with the positioning groove. When the upper mold base is assembled with the second recess, the lower outer wall of the upper mold base contacts and limits the contact with the inner wall of the second recess.

[0011] As a preferred embodiment, the lower end of the upper mold base has a third recess extending upward, the connecting post is located at the center of the third recess, the third recess is provided with a step for contacting the elastic wave, the step extends circumferentially along the central axis of the connecting post, the connecting post is located within the inner perimeter of the step, and the wire groove is provided on the step.

[0012] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly achieves synchronous one-time bonding and positioning of the drum paper, the spring, and the voice coil by placing the drum paper in the first recess and applying glue, then placing the spring on the drum paper, and finally mounting the voice coil on the connecting post and then assembling the upper mold base onto the lower mold base. In particular, the setting of the positioning groove and the wire groove is conducive to the placement and limitation of the lead wires of the drum paper, the spring, and the voice coil in the lower mold base and the upper mold base, respectively, so as to facilitate subsequent bonding and fixing operations. Moreover, after the upper and lower mold bases are assembled and connected, uniform and stable pressure can be applied to the whole formed by the three components, which improves the bonding effect of the components and the product yield, ensures the stability of the product in use, and has a wide range of applications.

[0013] Secondly, the setting of the limiting part is conducive to the contact limiting of the diaphragm and spring on the lower mold base, so as to facilitate the positioning and bonding operation between the diaphragm and spring. The operation is simple and the assembly is convenient. At the same time, the setting of the anti-fooling part and anti-fooling groove is conducive to the positioning and assembly connection between the upper mold base and the lower mold base, thereby ensuring the precise alignment between the voice coil and the diaphragm before bonding and positioning. Combined with the setting of the second recess, it helps to improve the contact stability after the upper and lower mold bases are assembled and connected, thereby ensuring the bonding and pressure holding effect of the components and the usability is excellent.

[0014] Furthermore, the step design helps the spring to be pressed to a preset, precise height, avoiding excessive pressure that could cause the glue to be squeezed out, thus ensuring a strong bond between the spring and the drum paper.

[0024] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0025] A jig for assembling a paper spring ring includes an upper mold base 10 and a lower mold base 20, which are connected for assembly.

[0026] The lower end of the upper mold base 10 is provided with a connecting post 11 for positioning the voice coil 13 and a wire groove 12 for positioning the voice coil lead wire. The outer end of the wire groove 12 passes through the upper mold base 10 and is provided with a wire outlet 121. There are two wire grooves 12 arranged symmetrically at the lower end of the upper mold base 10. Correspondingly, there are two wire outlets 121.

[0027] The upper end of the lower mold base 20 is provided with a first recess 21 for placing and positioning the drum paper 25. A positioning groove 211 is provided on one side of the first recess 21 to match and position the drum paper 25 and the extension 27 of the spring wave 26.

[0028] In use, first place the drum paper in the first recess and position the extension of the drum paper in the positioning groove. Then, apply glue to the drum paper corresponding to the bonding positions of the spider and voice coil. Align the extension of the spider with the positioning groove, then place the spider in the first recess and bond it to the drum paper, positioning the extension of the spider in the positioning groove. Install the voice coil on the connecting post, then guide the lead wire of the voice coil out of the upper mold base from the wire outlet. Finally, assemble the upper mold base from top to bottom onto the upper end of the lower mold base to directly position the voice coil and drum paper, and use the weight of the upper mold base to maintain pressure on the drum paper, spider, and voice coil. After applying glue to the first recessed area using a diaphragm, the spring is placed on the diaphragm. Then, the voice coil is installed on the connecting post, and the upper mold base is assembled onto the lower mold base. This achieves simultaneous, one-time bonding and positioning of the diaphragm, spring, and voice coil. In particular, the positioning groove and wire groove facilitate the placement and positioning of the leads of the diaphragm, spring, and voice coil on the lower mold base and upper mold base, respectively, which is convenient for subsequent bonding and fixing operations. Furthermore, after the upper and lower mold bases are assembled and connected, uniform and stable pressure can be applied to the whole formed by the three components, improving the bonding effect of the components and the product yield, ensuring the stability of product use, and having a wide range of applications.

[0029] Furthermore, the lower mold base 20 has an upwardly extending limiting part 22. The limiting part 22 is provided with several parts arranged at intervals around the edge of the first recess 21. The inner wall of the limiting part 22 contacts and limits the outer wall of the diaphragm and the outer wall of the spring. The positioning groove 211 is provided on any of the limiting parts 22. In this way, the setting of the limiting part is conducive to the contact and limiting of the diaphragm and the spring on the lower mold base, so as to facilitate the positioning and bonding operation between the diaphragm and the spring. The operation is simple and the assembly is convenient.

[0030] Furthermore, the upper mold base 10 is provided with a foolproof part 14 on its edge, and the upper edge of the lower mold base 20 is provided with a foolproof groove 23 that matches and positions the foolproof part. The foolproof part 14 is adapted to the foolproof groove 23 to realize the positioning and assembly between the upper mold base 10 and the lower mold base 20.

[0031] Specifically, the upper end of the lower mold base 20 is also provided with a second recess 24 for contact assembly with the upper mold base. The first recess 21 is located at the center of the second recess 24. The anti-misalignment groove 23 is located on one side of the edge of the second recess 24 and is correspondingly provided with the positioning groove 211. When the upper mold base 10 is assembled in the second recess 24, the lower outer wall of the upper mold base 10 contacts and limits the contact with the inner wall of the second recess 24. Thus, the setting of the anti-misalignment part and the anti-misalignment groove is conducive to the positioning assembly connection between the upper mold base and the lower mold base, thereby ensuring the accurate alignment and bonding positioning operation between the voice coil and the drum paper. In conjunction with the setting of the second recess, it is beneficial to improve the contact stability after the upper and lower mold bases are assembled and connected, thereby ensuring the bonding and pressure holding effect of the component and its usability.

[0032] Furthermore, the lower end of the upper mold base 10 has a third recess 15 extending upward, the connecting post 11 is located at the center of the third recess 15, and the third recess 15 is provided with a step 151 for contacting the spring wave. The step 151 extends circumferentially along the central axis of the connecting post 11, and the connecting post 11 is located within the inner perimeter of the step 151. The groove 12 is provided on the step 151. Thus, the step is designed to help the spring wave be pressed to a preset, precise height, avoiding excessive pressure that could cause the glue to be over-squeezed, thereby ensuring the strong adhesion between the spring wave and the drum paper.

[0033] The key design feature of this utility model lies in its design of an upper mold base and a lower mold base. The process involves placing a diaphragm in the first recessed area, applying adhesive, placing the spring on the diaphragm, and then mounting the voice coil on the connecting post before assembling the upper mold base onto the lower mold base. This achieves simultaneous, one-time bonding and positioning of the diaphragm, spring, and voice coil. In particular, the positioning groove and wire groove facilitate the placement and positioning of the leads for the diaphragm, spring, and voice coil on the lower mold base and upper mold base, respectively, thus aiding in subsequent bonding and fixing operations. Furthermore, after the upper and lower mold bases are assembled and connected, uniform and stable pressure can be applied to the entire structure formed by the three components, improving the bonding effect and product yield, ensuring product stability, and broad applicability.

[0034] Secondly, the setting of the limiting part is conducive to the contact limiting of the diaphragm and spring on the lower mold base, so as to facilitate the positioning and bonding operation between the diaphragm and spring. The operation is simple and the assembly is convenient. At the same time, the setting of the anti-fooling part and anti-fooling groove is conducive to the positioning and assembly connection between the upper mold base and the lower mold base, thereby ensuring the precise alignment between the voice coil and the diaphragm before bonding and positioning. Combined with the setting of the second recess, it helps to improve the contact stability after the upper and lower mold bases are assembled and connected, thereby ensuring the bonding and pressure holding effect of the components and the usability is excellent.

[0035] Furthermore, the step design helps the spring to be pressed to a preset, precise height, avoiding excessive pressure that could cause the glue to be squeezed out, thus ensuring a strong bond between the spring and the drum paper.

[0036] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
