[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0027] like Figure 1 and Figure 2 As shown, the functional module assembly fixture of the embodiment of the utility model includes a base 1, a fixing frame 2 and a cover plate 3.

[0028] The base 1 may be made of plastic, metal or other materials, and the base 1 may be integrally formed. The fixing frame 2 is disposed on the base 1, and the fixing frame 2 is provided with a limiting groove 21 for placing electronic components. Figure 1 and 2 As shown, the fixed frame 2 can be generally in the shape of a square frame, and the fixed frame 2 can be fixed on the base 1. For example, the fixed frame 2 can be integrally formed on the base 1, and the limiting groove 21 can be generally a rectangular groove. The peripheral edge of the fixed frame 2 can be provided with a circle of flanges, and the limiting groove 21 can be formed in the space surrounded by the flanges.

[0029] The cover plate 3 is provided with an assembly hole 31. The cover plate 3 is rotatably connected to the base 1 and has a first position and a second position. In the first position, the cover plate 3 is buckled on the electronic component that is at least partially located in the limiting groove 21, and the assembly hole 31 is arranged opposite to the installation area on the electronic component for installing the functional module. In the second position, the cover plate 3 releases the buckling of the electronic component.

[0030] For example, the cover plate 3 can be a rectangular plate, and a mounting area specially used for mounting the functional module is reserved on the electronic component. Specifically, the electronic component can be a three-in-one bottom shell of a mobile phone, and a rectangular mounting area can be reserved on the bottom shell, and the mounting area is used to fix the speaker. In some other embodiments, the functional module can also be a camera, a microphone, and other modules.

[0031] The bottom edge of the cover plate 3 can be rotatably assembled with the base 1 through a pivot, etc. When in use, the cover plate 3 can be flipped upwards. At this time, the cover plate 3 is switched to the first position. Figure 1 As shown, in the first position, the assembly hole 31 on the cover plate 3 can be arranged opposite to the installation area, that is, the extension direction of the assembly hole 31 is perpendicular to the installation area. At this time, the speaker can be passed through the assembly hole 31 and fixed at the installation area.

[0032] Specifically, the speaker may be provided with foam, and the foam may be provided with an adhesive. Before assembly, the centrifugal paper of the adhesive on the foam may be torn off. After the speaker passes through the assembly hole 31, the adhesive on the foam may be used to bond and fix the speaker to the safe area of ​​the electronic component.

[0033] After the speaker is assembled, the cover plate 3 can be flipped down. At this time, the cover plate 3 is switched to the second position. Figure 2 At this time, the electronic component bonded with the speaker can be removed from the limiting groove 21.

[0034] The functional module assembly fixture of the embodiment of the utility model can limit the assembly orientation, angle, etc. of the functional module through the assembly hole 31 on the cover plate 3 when assembling the functional module, that is, the limiting contact between the hole wall of the assembly hole 31 and the outer peripheral side of the functional module can ensure that the fitting end face of the functional module is parallel to the installation area, thereby ensuring the assembly accuracy of the functional module, improving the situation of foam being pressed and assembly offset, and further eliminating the noise of the speaker (functional module), improving the sound experience, and also improving the pass rate of the entire assembly line.

[0035] In some embodiments, the cover plate 3 is provided with an avoidance groove 33, and the avoidance groove 33 is used to avoid a set position on the electronic component. Figure 1 and Figure 2 As shown, the avoidance groove 33 can be a rectangular groove, and the avoidance groove 33 can be arranged at the edge position relative to the rotation assembly position of the cover plate 3 and the cover plate 3, and the avoidance groove 33 can be located on the right side of the assembly hole 31 and arranged at a distance from the assembly hole 31.

[0036] Since there are some protruding parts or positions (set parts) on the electronic components, when the cover 3 is buckled on the electronic components, the set parts can be matched in the avoidance groove 33, so as to play an avoidance role and avoid the situation where the protruding set parts cause the cover 3 to be buckled unevenly.

[0037] In some embodiments, at least one limiting hole 34 is provided on the cover plate 3 , the electronic component includes a protective shell, the protective shell is provided with a limiting portion, and the limiting hole 34 is used for the limiting portion to be plugged in and matched to achieve limiting constraints on the protective shell and the cover plate 3 .

[0038] For example, the assembled electronic components may be parts of mobile phones. Since the electronic components need to move on the assembly line, in order to avoid scratches, etc., a protective shell is usually required on the electronic components. The protective shell may specifically be a jelly shell, a rubber shell, etc. A limiting portion may be integrally formed on the protective shell. For example, the limiting portion may be a protrusion or a bump protruding from the surface of the protective shell.

[0039] The cover plate 3 can be provided with limiting holes 34 whose number is the same as the limiting parts. When the cover plate 3 is switched to the first position and buckled on the electronic component, the limiting parts on the protective shell can be plugged into the corresponding limiting holes 34, thereby achieving the positioning effect of the electronic component and further improving the precision and accuracy of assembly.

[0040] In some embodiments, there are multiple limiting holes 34 , which are disposed between the assembly hole 31 and the connection between the cover plate 3 and the base 1 , and are spaced apart along the extension direction of the swing axis of the cover plate 3 .

[0041] For example, Figure 1 and Figure 2 As shown, there can be two limit holes 34, both of which can be waist-shaped holes, and the two limit holes 34 can be arranged at intervals in the left and right directions. The linear arrangement of multiple limit holes 34 can make the multiple limit positions of the cover body and the electronic components arranged in a linear manner, thereby playing the role of stopping the electronic components from rotating, further ensuring the precision and accuracy of assembly.

[0042] In some embodiments, the base 1 includes a plate portion 11 and a protrusion 12, the protrusion 12 protrudes to one side of the plate portion 11, the fixing frame 2 is detachably assembled on the plate portion 11 and is located on the same side of the plate portion 11 as the protrusion 12, and the cover plate 3 is rotatably connected to the protrusion 12.

[0043] For example, Figure 1 As shown, the plate portion 11 can be generally in the shape of a rectangular plate, the protrusion 12 can be integrally formed on the bottom side of the plate portion 11 and extended along the bottom edge of the plate portion 11, and the protrusion 12 can protrude toward the rear side of the plate portion 11. The fixing frame 2 can be mounted on the rear side of the plate portion 11 by means of fasteners such as screws, thereby making the fixing frame 2 replaceable, so that fixing frames 2 of different types and sizes can be mounted on the plate portion 11, meeting the use needs of assembly functional modules of different electronic components.

[0044] The cover plate 3 can be rotatably assembled with the protrusion 12 via a pivot or the like. The arrangement of the protrusion 12 facilitates the spatial dislocation arrangement of the cover plate 3 and the plate portion 11 , thereby satisfying the need for buckling the cover plate 3 with electronic components on the fixing frame 2 .

[0045] In some embodiments, the protrusion 12 extends along the width direction of the plate portion 11, and the cover plate 3 is rotatably connected to the protrusion 12 through a plurality of hinges 4, and the plurality of hinges 4 are arranged at intervals along the width direction of the plate portion 11. Figure 1 and Figure 2 As shown, two hinges 4 may be provided, and the two hinges 4 may be spaced apart in the left-right direction.

[0046] In some embodiments, the cover plate 3 is made of a transparent material. For example, the cover plate 3 may be made of tempered glass, acrylic plate, plastic, etc. Thus, the electronic components below can be seen through the cover plate 3, so that the situation below the cover plate 3 can be directly understood.

[0047] In some embodiments, the length dimension of the assembly hole 31 is not less than 3 mm. For example, the assembly hole 31 may extend along the thickness direction of the cover plate 3 and penetrate the cover plate 3. The length dimension of the assembly hole 31 may be regarded as the thickness dimension of the cover plate 3. The thickness dimension of the cover plate 3 may be 3 mm, 4 mm, 5 mm, etc. Thus, the moving stroke of the functional module in the assembly hole 31 may be increased, thereby enhancing the limiting effect and further ensuring the precision and accuracy of the assembly.

[0048] In some embodiments, the fixing frame 2 is provided with a slot 22, and the slot 22 connects the limiting slot 21 with the outer side of the fixing frame 2. Figure 1 and Figure 2 As shown, a slot 22 may be provided on both the left and right sides of the fixing frame 2, and the two slots 22 may be arranged opposite to each other and communicate with the limiting slot 21. When in use, the slot 22 may be inserted with a person's finger, thereby facilitating the placement or removal of electronic components into or from the limiting slot 21.

[0049] In some embodiments, the cover plate 3 is provided with a plurality of openings 32 connected to the assembly hole 31, and the plurality of openings 32 are arranged at intervals along the circumference of the assembly hole 31. Figure 1 and Figure 2 As shown, the assembly hole 31 may be a rectangular hole, and four openings 32 may be provided. The four openings 32 may be circular holes, and the four openings 32 may be respectively provided at the four corners of the assembly hole 31 .

[0050] When assembling the functional module, especially when the functional module passes through the assembly hole 31 and fits with the electronic component, the four openings 32 can be used for the gas between the functional module and the electronic component to be discharged, thereby facilitating the functional module to pass through the assembly hole 31 on the one hand, and preventing the gas from being trapped between the functional component and the electronic component on the other hand, avoiding the situation where a large number of bubbles are stored at the bonding point, thereby ensuring the strength and effect of the bonding.

[0051] In some embodiments, along the extension direction of the assembly hole 31 , the projection of the hole contour of the assembly hole 31 is consistent with the outer peripheral contour of the installation area or is located within the range of the outer peripheral contour of the installation area.

[0052] For example, the extension direction of the assembly hole 31 can be the front-to-back direction, and the hole contour of the assembly hole 31 and the outer peripheral contour of the installation area can both be quadrilaterals, wherein the hole contour and the outer peripheral contour can be exactly the same. In other embodiments, the outer peripheral contour of the installation area can also be slightly larger than the hole contour, thereby playing a role in compensating for assembly errors.

[0053] The following describes the assembly method of the embodiment of the utility model.

[0054] The assembly method of the utility model embodiment comprises the following steps:

[0055] S1: Switch the cover plate 3 to the second position, and then place the electronic component in the limiting groove 21. Specifically, the cover plate 3 can be turned down and overlapped on the protrusion 12, as shown in FIG. Figure 2 As shown, at this time, the limiting groove 21 is completely exposed, so that it is convenient to place the electronic component directly in the limiting groove 21.

[0056] S2: Switch the cover plate 3 to the first position and buckle it onto the electronic component. For example, after the electronic component is placed, the cover plate 3 can be turned over and buckled onto the electronic component. Figure 1 As shown, at this time, a portion of the bottom of the electronic component will be blocked by the cover 3, and due to the installation position of the fixing frame 2, the cooperation of the protrusion 12 of the protective shell and the limiting hole 34, the assembly hole 31 on the cover 3 can be aligned with and fit with the installation area on the electronic component.

[0057] S3: Fix the functional module to the installation area on the electronic component through the assembly hole 31. For example, the operator can directly absorb the speaker with a magnetic pen, and after tearing off the centrifugal paper on the foam of the speaker, the functional module can be passed through the assembly hole 31. The inclination and horizontality of the functional module can be adjusted by the limit stop of the assembly hole 31 and the peripheral wall of the functional module, so that the functional module can be vertically pressed in the installation area of ​​the electronic component, ensuring the assembly precision and accuracy of the functional module.

[0058] It has been verified in practice that the defective rate of the speaker assembly without the functional module assembly fixture of the embodiment of the utility model is as high as 2.17%, while the defective rate of the speaker assembly with the functional module assembly fixture of the embodiment of the utility model can be controlled within 0.2%. This improves the situation of foam being pressed and the functional module assembly being offset, and also improves the pass rate of the entire assembly line.
