Description

Technical Field

[0001] This utility model belongs to the field of clamping equipment, and specifically relates to a precise alignment clamp for a mobile phone side button module. Background Technology

[0002] The side button module fixture is a specialized tooling fixture used in mobile phone manufacturing for the assembly and inspection of side button modules. During the assembly process, the lack of stable positioning support and clamping guidance can easily lead to problems such as uneven gaps between the buttons and the frame, stuck presses, or a loose feel. These problems arise because the side button components are tiny, making it difficult to consistently control the placement angle and force during manual operation. Combined with the accumulated dimensional tolerances of the housing and buttons themselves, this can easily cause the gap between the conductive base and the trigger element to deviate from design standards. Conventional solutions often rely on operator experience to repeatedly adjust the component position or increase the frequency of manual inspections to filter out defective products. However, these methods not only prolong the assembly time per unit but also, due to the subjective differences in human judgment, are difficult to guarantee consistency, leading to recurring issues such as fluctuating button feel and functional failures. Therefore, a new structure is needed to solve the above-mentioned technical problems. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a precise alignment fixture for mobile phone side button modules, thereby solving the problems mentioned in the background.

[0004] This utility model is achieved through the following technical solution: a precise alignment fixture for a mobile phone side button module, comprising: a base assembly and a clamping assembly. The upper surface of the base assembly is equipped with a clamping assembly for clamping and fixing the mobile phone side button module. The clamping assembly includes a clamping member one and a clamping member two. The clamping member two is slidably installed inside the clamping member one. The clamping member one includes a mounting block and a clamping block one. The upper surface of the mounting block is equipped with the clamping block one. The clamping member two includes a slider and a clamping block two. The upper surface of the slider is integrally formed with the clamping block two.

[0005] In a preferred embodiment, the base assembly includes a base plate and a fixing block. The fixing block is integrally formed symmetrically on the outer surface of the base plate, and a threaded hole is formed through the upper surface of the fixing block. An mounting block is fixed to the center of the upper surface of the base plate by a fixing bolt.

[0006] In a preferred embodiment, a clamping block 1 is integrally formed on the upper edge of the left side surface of the mounting block, a slider is installed through the lower side of the left side surface of the mounting block, and a clamping block 2 is integrally formed on the left edge of the upper surface of the slider. The clamping block 1 and clamping block 2 have the same structure. In use, the clamping assembly effectively avoids the misalignment of the side key and the hole position of the middle frame and the buckle caused by the displacement of the workpiece during the assembly process, ensuring that the two always maintain the assembly accuracy, thereby reducing button function problems.

[0007] In a preferred embodiment, the clamping block one and clamping block two are positioned to match each other, and the clamping block one and clamping block two are arranged in a mirror image symmetrically. A threaded rod is threadedly connected to the center of the left side surface of the slider, and the inner end of the threaded rod is rotatably connected to the mounting block.

[0008] In a preferred embodiment, the outer surface of the left end of the slider is threadedly connected to the outer surface of the threaded rod. The cross-section of the slider is an inverted U-shaped structure. A rocker arm is installed at the left end of the threaded rod. In use, the clamping block one relies on the mounting block to achieve fixed reference positioning, which can provide a stable single-sided positioning reference for the side button module or the middle frame of the mobile phone, avoiding alignment deviation caused by reference shaking. At this time, the clamping block two, together with the slide groove and the rubber clamping plate, can adapt to side button modules of different sizes.

[0009] In a preferred embodiment, a sliding groove is provided on the inner surface of both clamping block one and clamping block two, and a circular rubber clamping plate is slidably mounted inside the sliding groove.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are: 1. By setting a clamping component, the upper surface of the base component is equipped with a clamping component for clamping and fixing the side button module of the mobile phone. When in use, the clamping component effectively avoids the misalignment of the side button and the hole position and buckle of the middle frame caused by the displacement of the workpiece during the assembly process, ensuring that the two always maintain the assembly accuracy, thereby reducing button function problems.

[0011] 2. By setting clamping block one and clamping block two, clamping block one includes a mounting block and clamping block one. The upper surface of the mounting block is equipped with clamping block one. Clamping block two includes a slider and clamping block two. The upper surface of the slider is integrally formed with clamping block two. In use, clamping block one relies on the mounting block to achieve fixed reference positioning, which can provide a stable single-sided positioning reference for the side button module or the middle frame of the mobile phone, avoiding alignment deviation caused by reference shaking. At this time, clamping block two, together with the sliding groove and rubber clamping plate, can adapt to side button modules of different sizes. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figs. 1-3 As the first embodiment of this utility model: a precise alignment fixture for a mobile phone side button module, comprising: a base assembly and a clamping assembly, wherein a clamping assembly for clamping and fixing the mobile phone side button module is mounted on the upper surface of the base assembly, the clamping assembly includes a clamping member one and a clamping member two, the clamping member two is slidably mounted inside the clamping member one, the clamping member one includes a mounting block 200 and a clamping block one 220, the clamping block one 220 is mounted on the upper surface of the mounting block 200, the clamping member two includes a slider 300 and a clamping block two 310, the clamping block two 310 is integrally formed on the upper surface of the slider 300;

[0021] The base assembly includes a base plate 100 and a fixing block 110. The fixing block 110 is integrally formed symmetrically on the outer surface of the base plate 100. A threaded hole is formed through the upper surface of the fixing block 110. An mounting block 200 is fixed to the center of the upper surface of the base plate 100 by a fixing bolt 210.

[0022] A clamping block 220 is integrally formed on the upper edge of the left side surface of the mounting block 200. A slider 300 is installed through the lower side of the left side surface of the mounting block 200. A clamping block 310 is integrally formed on the left edge of the upper side surface of the slider 300. The clamping block 220 and the clamping block 310 have the same structure.

[0023] The positions of clamping block 1 220 and clamping block 2 310 are matched with each other. The clamping block 1 220 and clamping block 2 310 are set in a mirror image symmetrically. A threaded rod 340 is threadedly connected through the center of the left side surface of the slider 300. The inner end of the threaded rod 340 is rotatably connected to the mounting block 200.

[0024] The outer surface of the left end of the slider 300 is threadedly connected to the outer surface of the threaded rod 340. The cross section of the slider 300 is an inverted U-shaped structure. A rocker arm 350 is installed at the left end of the threaded rod 340.

[0025] In use, the user first prepares the side button module of the mobile phone that needs to be clamped and fixed. Then, with one hand, the user places it between clamping block 220 and clamping block 310. After placement, the user's other hand can hold the joystick 350. The user can then rotate the joystick 350. When the joystick 350 rotates, it drives the threaded rod 340 to rotate. When the threaded rod 340 rotates, it drives the left side surface of the slider 300 to move. At this time, the slider 300 moves through the threaded rod 340, thus allowing the slider 300 to pass through... The mounting block 200 moves, and when the slider 300 moves via the threaded rod 340, the clamping block 310 on its upper surface also moves accordingly, causing the clamping block 220 and the clamping block 310 to move towards each other. At this time, the clamping block 220 and the clamping block 310 moving towards each other will clamp and fix the mobile phone side button module between them, so as to perform subsequent operations. During use, the clamping components effectively avoid the misalignment of the side button and the middle frame hole and buckle caused by the workpiece displacement during the assembly process, ensuring that the two always maintain the assembly accuracy, thereby reducing button function problems.

[0026] Please see Figs. 1-3As a second embodiment of the present invention: based on the description in the above embodiments, further, a groove 320 is provided on the inner surface of both the clamping block 220 and the clamping block 310, and a circular rubber clamping plate 330 is installed inside the groove 320 with damping sliding.

[0027] In use, before clamping the phone side button module through the operation steps of the first embodiment, the user can first slide the rubber clamping plate 330 on the inner surface of clamping block 1 220 and clamping block 2 310, so that the rubber clamping plate 330 moves along the slide groove 320. The user can slide the position of the rubber clamping plate 330 according to the structure of the phone side button module to be clamped. After the position of the rubber clamping plate 330 is moved, the user can clamp and fix the phone side button module through the operation steps of the first embodiment. Since clamping block 1 220 relies on mounting block 200 to achieve fixed reference positioning, it can provide a stable single-sided positioning reference for the side button module or the phone frame, avoiding alignment deviation caused by reference shaking. At this time, clamping block 2 310, together with slide groove 320 and rubber clamping plate 330, can adapt to side button modules of different sizes.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
