Description

Technical Field

[0001] This utility model relates to the field of hearing aid manufacturing technology, and in particular to a hearing aid cover assembly and positioning fixture. Background Technology

[0002] Hearing aids are devices that provide hearing assistance to people with hearing impairments. Their outer casing is the main component that protects the internal functional parts. The main body of a hearing aid typically consists of an upper shell and a lower shell that interlock. The upper shell houses the circuit boards and other functional components, while the lower shell houses the control buttons. During assembly, the control buttons are pre-installed in the lower shell, the functional components are assembled in the upper shell, and finally, the upper and lower shells are interlocked to connect the control buttons and functional components.

[0003] Currently, the assembly of the upper and lower shells is usually done by pressing and fastening them by hand. Because the surface of the shell is relatively smooth and a certain amount of force needs to be applied when fastening, it is inconvenient to operate manually and is easy to slip, causing the hearing aid to slip off and cause damage. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a hearing aid cover assembly positioning fixture, which has the advantages of convenient assembly and improved assembly efficiency.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] According to an embodiment of this disclosure, a hearing aid cover assembly positioning fixture is provided, including a fixture body. The fixture body is provided with a first contour groove adapted to the lower shell. The first contour groove is provided with a second contour groove adapted to the control button. The first contour groove is provided with a pre-adhesive layer. The pre-adhesive layer is tightly adhered to the pre-adhesive layer and can pre-adhere and fix the lower shell in the first contour groove, and the lower shell can be detached from the pre-adhesive layer.

[0007] The bottom of the fixture body is provided with an annular groove, and the outer edge of the bottom of the fixture body extends downward to form a supporting skirt to create a height difference with the middle of the fixture body. The bottom of the fixture body is provided with several positioning suction cups located inside the supporting skirt, which are used to adhere to the workbench surface to prevent the fixture body from slipping and fixing it.

[0008] To achieve the above technical solution, during hearing aid assembly, the positioning fixture is placed on a flat workbench and supported by the supporting skirt. The positioning suction cup adheres to the workbench, fixing the fixture body relatively to the workbench. The lower shell, pre-installed with control buttons, is then placed in the first contoured groove, while the control buttons are placed in the second contoured groove. A pre-adhesive layer secures the lower shell, ensuring its vertical orientation. Next, the upper shell, pre-installed with functional components, is aligned with the lower shell, and pressure is applied to lock them together, thus assembling the hearing aid. The assembled hearing aid can then be easily removed. Since the adhesive strength of the pre-adhesive layer can be adjusted as needed, removal is also very convenient. The cooperation between the first contoured groove and the pre-adhesive layer ensures the lower shell is stably and vertically positioned within the positioning fixture, facilitating force application during assembly, improving assembly convenience and efficiency, and effectively preventing the hearing aid from slipping and being damaged during assembly.

[0009] In some exemplary embodiments, the bottom of the fixture body is provided with a plurality of mounting holes, and the top of the positioning suction cup is provided with a mounting block, which is used to be embedded in the mounting holes.

[0010] The above technical solution achieves the goal of making the positioning suction cup easier and more secure to install by using the mounting block and mounting hole together.

[0011] In some exemplary embodiments, the fixture body has an assembly groove, the first contour groove is disposed in the assembly groove, and the sidewall of the assembly groove is an inclined guide surface.

[0012] The above technical solution allows for the provision of sufficient assembly space to facilitate manual operation.

[0013] In some exemplary embodiments, the fixture body is made of a plastic material with elastic deformation properties.

[0014] The above technical solution reduces damage caused by excessive force during assembly, which could result in rigid contact between the lower shell and the fixture body.

[0015] In some exemplary embodiments, the fixture body is integrally formed using 3D printing.

[0016] To achieve the above technical solution, since the hearing aid manufacturing process requires the use of 3D printers, such as for ear molds, the fixture body can be integrally formed using 3D printing. This allows for on-site processing, which is convenient and cost-effective, and also enables customized design and processing as needed.

[0017] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0018] This utility model embodiment provides a hearing aid cover assembly positioning fixture, including a fixture body. The fixture body has a first contoured groove adapted to the lower shell, and a second contoured groove adapted to the control buttons is provided in the first contoured groove. The first contoured groove has a pre-adhesive layer, which is tightly adhered to the pre-adhesive layer and can pre-adhere and fix the lower shell in the first contoured groove, and the lower shell can be detached from the pre-adhesive layer. The bottom of the fixture body has an annular groove, and the outer edge of the bottom of the fixture body extends downward to form a supporting skirt to form a height difference with the middle of the fixture body. The bottom of the fixture body is provided with a plurality of positioning suction cups located inside the supporting skirt for adhering to the work surface to prevent slipping and fix the fixture body. When assembling a hearing aid, the positioning fixture is placed on a flat workbench and supported by the supporting skirt. The positioning suction cup adheres to the workbench, fixing the fixture body relatively to the workbench. The lower shell, pre-installed with control buttons, is then placed in the first contoured groove, while the control buttons are placed in the second contoured groove. A pre-adhesive layer secures the lower shell, ensuring it remains vertical. Next, the upper shell, pre-installed with functional components, is aligned with the lower shell, and pressure is applied to lock them together, thus assembling the hearing aid. The assembled hearing aid can then be easily removed. Since the adhesive strength of the pre-adhesive layer can be adjusted as needed, removal is also very convenient. The cooperation between the first contoured groove and the pre-adhesive layer ensures the lower shell is stably and vertically positioned within the positioning fixture, making it easier to apply force during assembly, improving assembly convenience and efficiency, and effectively preventing the hearing aid from slipping and being damaged during assembly.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1 to 3 As shown, this utility model embodiment provides a hearing aid cover assembly positioning fixture, including fixture body 10. The fixture body 10 is provided with a first contour groove 11 adapted to the lower shell. The first contour groove 11 is provided with a second contour groove 12 adapted to the control button. The first contour groove 11 is provided with a pre-adhesive layer. The pre-adhesive layer is tightly bonded to the lower shell and can pre-adhere and fix the lower shell in the first contour groove 11, and the lower shell can be detached from the pre-adhesive layer.

[0026] The jig body 10 is made of a plastic material with elastic deformation properties, thereby reducing damage caused by rigid contact between the lower shell and the jig body 10 due to excessive force during assembly. It is understood that the plastic material only needs to have slight elastic deformation properties. Preferably, the jig body 10 is integrally formed by 3D printing. Since the hearing aid 30 needs to be processed by a 3D printer, such as the processing of the ear mold, the jig body 10 is integrally formed by 3D printing, which can realize on-site processing, which is convenient and cost-effective, and can be customized according to needs. Of course, in other embodiments, it can also be integrally formed by injection molding.

[0027] The first contour groove 11 has at least a portion of a contoured surface that can conform to the lower shell. The pre-adhesive layer can be formed by applying hot melt adhesive or double-sided tape to this contoured surface. The portion of the pre-adhesive layer used for bonding the lower shell only needs to have low tack, sufficient to bond and fix the lower shell so that it does not easily wobble, and allowing the lower shell to detach from the pre-adhesive layer after a certain force is applied. The first contour groove 11 and the second contour groove 12 are naturally formed during the molding of the fixture body 10. Simultaneously, an assembly slot 15 is provided on the fixture body 10, and the first contour groove 11 is disposed within the assembly slot 15. The sidewalls of the assembly slot 15 are inclined guide surfaces, thereby reserving a certain assembly space for easy manual operation.

[0028] Furthermore, an annular groove 13 is provided at the bottom of the fixture body 10, and a supporting skirt 14 extends downward from the bottom outer edge of the fixture body 10 to form a height difference with the middle of the fixture body 10. Several positioning suction cups 20 are provided at the bottom of the fixture body 10 inside the supporting skirt 14 for adhering to the workbench surface to prevent the fixture body 10 from slipping and fixing it.

[0029] The fixture body 10 has several mounting holes at its bottom, and the positioning suction cup 20 has a mounting block 21 at its top. The mounting block 21 is used to embed into the mounting holes and can be fixed to the fixture body 10 by adhesive, welding or snap-fit. The mounting block 21 and the mounting holes make the installation of the positioning suction cup 20 more convenient and reliable. In its natural state, the positioning suction cup 20 protrudes slightly from the lower end face of the supporting skirt 14 after installation, and the positioning suction cup 20 can deform. After the positioning fixture is placed on the worktable, it is pressed down until the supporting skirt 14 is in contact with the worktable, so that the positioning suction cup 20 deforms to expel the internal air and forms an adsorption force with the worktable, thus pre-fixing the fixture body 10. The supporting skirt 14 can support the fixture body 10.

[0030] When assembling the hearing aid 30, the positioning fixture is placed on a flat workbench and supported by the supporting skirt 14. At this time, the positioning suction cup 20 is attracted to the workbench, fixing the fixture body 10 relatively on the workbench. Then, the lower shell with the pre-installed control buttons is placed in the first contour groove 11, and the control buttons are placed in the second contour groove 12. The lower shell can be pre-adheded and fixed by the pre-adhesive layer to keep the lower shell in a vertical direction. Then, the upper shell with the pre-installed functional components is placed in the corresponding position with the lower shell, and a certain pressure is applied to make the two snap together, thus completing the assembly of the hearing aid 30. The assembled hearing aid 30 can then be removed. Since the adhesive strength of the pre-adhesive layer can be set as needed, it can also be removed very easily. The cooperation between the first contour groove 11 and the pre-adhesive layer allows the lower shell to be stably and vertically placed in the positioning fixture, making it easier to apply force during assembly, improving assembly convenience and efficiency, and effectively preventing the hearing aid 30 from slipping and being damaged during the assembly process.

[0031] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
