Description

Technical Field

[0001] This invention relates to the field of electronic product manufacturing technology, and in particular to a pressure holding device. Background Technology

[0002] During the production process of wireless chargers, assemblies need to be installed into the housing. The specific steps include first connecting the assembly to the cover plate, then applying adhesive to the housing, and finally pressing the assembly directly into the mounting groove of the housing for pressure holding. Due to the processing or organizational errors of the cover plate, assembly, and housing, cumulative tolerances occur after the assembly is installed into the housing. This results in uneven gaps between the assembly and the housing, reducing product processing quality and even causing the product to be rejected.

[0003] Therefore, a pressure-holding device is urgently needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a pressure-holding device that can make the gap between the assembly and the housing more uniform, thereby improving the product assembly accuracy and product yield.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A pressure-holding device for pressing an assembly into a mounting groove of a housing and maintaining pressure, comprising a positioning element, a limiting mechanism, and a pressure-holding cover plate. The positioning element positions the housing; the limiting mechanism includes a plurality of limiting elements, each separably disposed on the positioning element and evenly spaced along the circumference of the mounting groove of the housing positioned on the positioning element; the pressure-holding cover plate positions the assembly.

[0007] Driving the pressure-holding cover plate enables the assembly to be inserted into the mounting groove of the housing positioned on the positioning member, and the plurality of limiting members can limit the assembly during the process of the assembly being inserted into the mounting groove.

[0008] Optionally, the limiting member includes a limiting body and a limiting part, the limiting body being disposed on the positioning member; the limiting part being connected to the limiting body and having a rounded transition with the limiting body, the limiting part being located on the inner wall of the mounting groove of the housing positioned on the positioning member.

[0009] Optionally, the limiting body includes a support portion and a mounting portion disposed at the bottom of the support portion. The positioning member has a groove, and the mounting portion is inserted into the groove to position the limiting body.

[0013] Optionally, the positioning structure includes a first positioning groove formed on the positioning member.

[0014] Optionally, a second positioning groove is provided on the top of the positioning member, which can position the housing.

[0015] Optionally, it also includes a cover plate positioning mechanism disposed on the positioning member to position the pressure-holding cover plate as it moves toward the positioning member.

[0016] Optionally, the cover plate positioning mechanism includes two positioning posts, which are spaced apart on the positioning member, and the pressure-holding cover plate is provided with positioning holes that correspond one-to-one with the positions of the two positioning posts.

[0017] The beneficial effects of this invention are as follows:

[0018] When assembling an assembly and a housing using the pressure-holding device of the present invention, the assembly is positioned on the pressure-holding cover plate, the housing is positioned on the positioning member, and several limiting members are set on the positioning member.

[0033] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] After two parts are glued together, a pressure-holding device is usually needed to maintain pressure on the glued parts. Figure 1 As shown, this embodiment uses the assembly of the wireless charger assembly 100 and housing 200 as an example for explanation. After applying adhesive to the housing 200, the assembly 100 is inserted into the housing 200 and pressurized for a period of time to achieve the assembly of the assembly 100 and housing 200. Of course, the pressure-holding device in this embodiment does not limit the assembly and pressure holding of the wireless charger assembly 100 and housing 200.

[0035] This embodiment provides a pressure-holding device for pressing the assembly 100 into the mounting groove 201 of the housing 200 and maintaining pressure, such as... Figures 1 to 3 As shown, the pressure-holding device includes a positioning element 1, a limiting mechanism 2, and a pressure-holding cover plate 3. The positioning element 1 can position the housing 200. The limiting mechanism 2 includes a plurality of limiting elements 21, which are detachably disposed on the positioning element 1 and are evenly spaced circumferentially along the mounting groove 201 of the housing 200 positioned on the positioning element 1. The pressure-holding cover plate 3 can position the assembly 100. Driving the pressure-holding cover plate 3 can insert the assembly 100 into the mounting groove 201 of the housing 200 positioned on the positioning element 1, and the plurality of limiting elements 21 can limit the assembly 100 during the process of inserting the assembly 100 into the mounting groove 201.

[0036] When assembling the assembly 100 and the housing 200, the assembly 100 is positioned on the pressure-holding cover plate 3, and the housing 200 is positioned on the positioning member 1. Several limiting members 21 are then placed on the positioning member 1. The pressure-holding cover plate 3 is driven, and the assembly 100 is driven through the pressure-holding cover plate 3 and pressed into the housing 200. During the process of pressing the assembly 100 into the housing 200, the limiting members 21 limit the assembly 100 and install it into the housing 200 according to a preset trajectory. This allows the gap between the assembly 100 and the housing 200 after assembly to be evenly distributed, thereby improving the product assembly accuracy and product yield.

[0037] In detail, the pressure-holding device in this embodiment further includes a support mechanism 4, and a positioning member 1 is disposed on the support mechanism 4, so that the positioning member 1 can be installed to the required height. Optionally, the support mechanism 4 includes a base 41 and a support member 42, the support member 42 is disposed on the base 41, and the positioning member 1 is disposed on the support member 42. The support member 42 includes two opposing support plates, and the positioning member 1 is disposed on the top of the two support plates.

[0038] like Figure 3 and Figure 4As shown, the limiting member 21 includes a limiting body 211 and a limiting part 212. The limiting body 211 is disposed on the positioning member 1, and the positioning member 1 fixes the limiting body 211. The limiting part 212 is connected to the limiting body 211 and transitions with the limiting body 211 at a rounded corner. The limiting part 212 is located on the inner wall of the mounting groove 201 of the housing 200 positioned on the positioning member 1. It can be understood that during the process of pressing the assembly 100 into the housing 200, the assembly 100 is pressed towards the center of the housing 200 by several limiting parts 212, thereby making the gap between the side wall of the assembly 100 and the inner wall of the mounting groove 201 uniform. In some optional embodiments, three or four limiting members 21 are provided. When the outer wall of the assembly 100 is cylindrical and the inner wall of the housing 200 is cylindrical or circular, the limiting members 21 can automatically center the assembly 100, which is more conducive to improving the assembly accuracy and product yield of the product. Of course, those skilled in the art can set the number of limiting members 21 to other quantities, which is not limited here.

[0039] Furthermore, the limiting body 211 includes a support portion 2111 and a mounting portion 2112 disposed at the bottom of the support portion 2111. A groove 11 is provided on the positioning member 1, and the mounting portion 2112 is inserted into the groove 11 to position the limiting body 211. Through the cooperation of the mounting portion 2112 and the groove 11, the limiting member 21 can be quickly positioned, improving the efficiency of installation and removal of the limiting member 21, thereby contributing to improved pressure holding efficiency of the product.

[0040] In detail, since the limiting member 21 is positioned by inserting the mounting part 2112 into the groove 11, the limiting member 21 is prone to jumping relative to the groove 11 during use. To solve the above problem, such as Figure 3 and Figure 4 As shown, the limiting mechanism 2 also includes a pressing member 22, which can press a plurality of limiting members 21 against the positioning member 1, thereby enabling the limiting members 21 to reliably perform the limiting function.

[0041] In some optional embodiments, the pressing member 22 is annular, so that several limiting members 21 can be fixed or released at the same time through the pressing member 22, which is beneficial to improve the installation and disassembly efficiency of the limiting members 21, thereby improving the pressure holding efficiency of the product.

[0042] To facilitate the positioning of the pressure member 22, such as Figure 3 and Figure 4 As shown, the positioning component 1 is provided with a positioning structure of positioning and pressing component 22.

[0043] In some optional embodiments, the positioning structure includes a first positioning groove 12 formed on the positioning member 1. Specifically, when the pressing member 22 presses against the limiting member 21, the pressing member 22 is engaged in the first positioning groove 12 to achieve rapid positioning of the pressing member 22.

[0044] In some alternative embodiments, such as Figure 3 and Figure 4 As shown, the top of the positioning component 1 is provided with a second positioning groove 13, which can position the housing 200. After the housing 200 is placed into the second positioning groove 13, the housing 200 can be positioned, which has high positioning efficiency and is conducive to improving the pressure holding efficiency of the product.

[0045] When the pressure-holding cover 3 moves the assembly 100 into the mounting slot 201, in order to ensure that the pressure-holding cover 3 moves accurately to the preset position, such as... Figures 2 to 4 As shown, the pressure-holding device in this embodiment also includes a cover plate positioning mechanism 5, which is disposed on the positioning member 1 to position the pressure-holding cover plate 3 when it moves toward the positioning member 1.

[0046] Optionally, the cover plate positioning mechanism 5 includes two positioning posts 51, which are spaced apart on the positioning member 1. The pressure-holding cover plate 3 is provided with positioning holes 31 that correspond one-to-one with the positions of the two positioning posts 51. It can be understood that when the pressure-holding cover plate 3 moves the assembly 100 toward the housing 200 positioned on the positioning member 1, the two positioning holes 31 can be slidably fitted onto one of the positioning posts 51, thereby achieving the positioning of the pressure-holding cover plate 3.

[0047] In order to better position the pressure-retaining component 22, the pressure-retaining component 22 is slidably inserted through the two positioning posts 51, so that the two positioning posts 51 can both position the pressure-retaining component 22 and position the pressure-holding cover plate 3.

[0048] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
