Description

Technical Field

[0001] This utility model relates to the field of electronic equipment processing equipment technology, specifically to a button sealing structure and a mobile phone production system. Background Technology

[0002] During mobile phone manufacturing and testing, it is often necessary to seal the buttons to meet performance requirements such as waterproofing and dustproofing. For example, in airtightness testing or waterproof adhesive coating processes, a sealing mechanism is needed to ensure a tight fit between the power button, volume buttons, and other openings. However, existing sealing mechanisms generally use a fixed structure, and the position and angle of the seal cannot be dynamically adjusted according to the actual layout of the phone buttons or positional deviations during production line transport. Since the button positions of different phone models may have an offset of ±2mm or more, and the positioning error of the same model of phone on the production line tray can reach ±1.5mm, fixed sealing mechanisms cannot accurately align with the button openings. Actual measured mating deviations often reach ±0.8mm, resulting in a gap between the seal and the button edge exceeding 0.3mm, far exceeding the ≤0.1mm standard required for waterproof testing. This leads to misjudgments in airtightness test results or waterproof adhesive overflow. In addition, for curved screen phones or irregularly shaped buttons with curvature, the fixed-angle seal cannot tightly fit the curved contour, further reducing the reliability of the seal. While existing technologies attempt to improve sealing accuracy through manual calibration or by increasing the contact area of ​​the seal, manual adjustment is inefficient and has unstable precision (human error ±0.5mm). Increasing the contact area may mask abnormal button assembly gaps, leading to missed inspections. Neither approach fundamentally solves the mismatch between the fixed structure and the dynamic button position, resulting in increased defect rates and low production efficiency in the mobile phone sealing process. There is an urgent need to develop a dynamic sealing mechanism that can adapt to changes in button position in real time to improve sealing accuracy and reliability. Summary of the Invention

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0022] Example 1:

[0023] See Figure 1 and Figure 2 As shown, this embodiment provides a button sealing structure, which includes: a movable mounting mechanism 100, the movable mounting mechanism 100 including a first assembly frame 110 and a sliding connector 130, one end of the sliding connector 130 being connected to the first assembly frame 110, and the other end having a positioning through hole 134 extending along a first direction X, the connector passing through the positioning through hole 134 so that the movable mounting mechanism 100 is connected to one side of the production line; and a sealing mechanism 200, the sealing mechanism 200 including a push driver 250, a mounting plate 210, and at least one A sealing assembly 220 and a displacement sensor 230 are provided. The push driver 250 is connected to the first assembly frame 110. The mounting plate 210 is connected to the working end of the push driver 250 to move toward / away from the production line via the push driver 250. The displacement sensor 230 is disposed on the mounting plate 210 and moves synchronously with the mounting plate 210. At least one of the sealing assemblies 220 is connected to the mounting plate 210 and is located on the side of the mounting plate 210 facing the production line to receive the sealing button.

[0024] In actual production and processing, the setting position of the sealing mechanism 200 is fixed. However, the product to be tested is difficult to accurately position to the working position of the sealing mechanism 200 due to factors such as inertia or equipment error, which may lead to poor sealing. In order to overcome the above problems, this application provides a button sealing structure that can adjust the position and perform high-precision positioning.

[0025] It should be noted that, for ease of description, in this embodiment, the pushing direction of the pusher 250 is defined as the first direction X, the extension direction of the production line is defined as the second direction Y, and the height direction of the equipment is defined as the third direction Z. The first direction X, the second direction Y, and the third direction Z are arranged perpendicularly to each other, and the first direction X and the second direction Y are located in the same plane.

[0026] See Figure 1 and Figure 2 As shown, the mobile mounting structure in this embodiment can be connected to one side of the production line and provides an installation connection platform for the sealing mechanism 200. The first assembly frame 110 has an "L" shaped structure and a protective plate 120 is connected to its top to prevent external structures from scratching the mobile phone.

[0027] In this embodiment, to achieve high compatibility with the production line, the positioning through hole 134 extends along the first direction X to connect to the side wall of the production line, thereby avoiding the edge structure of the production line. The sliding connector 130 includes a first connecting part 131, an extension part 132, and a second connecting part 133 connected in sequence. One end of the first connecting part 131 is connected to the first assembly frame 110, and the other end is connected to the extension part 132. The extension part 132 extends along the first direction X. The second connecting part 133 is connected to the extended end of the extension part 132 and extends along the second direction Y. At least one positioning through hole 134 is provided on the second connecting part 133. This achieves a reasonable layout between the above structures, thereby ensuring their connection stability.

[0028] See Figure 3 As shown, the sealing mechanism 200 in this embodiment further includes a second mounting bracket 260. One side of the second mounting bracket 260 is connected to the mounting plate 210, and the other side is slidably connected to the push driver 250, thereby forming all-round protection and fixation for the push driver 250. Further, the second mounting bracket 260 includes a locking part 261 and a sliding part 262. The locking part 261 and the sliding part 262 are perpendicularly connected to each other. The locking part 261 is connected to the mounting plate 210, and the sliding part 262 extends from the locking part 261 toward the first mounting bracket 110 and is slidably connected to the push driver 250.

[0029] Specifically, the mounting plate 210 is provided with at least one first locking hole 211, and the locking part 261 is provided with at least one second locking hole 263. The first locking hole 211 and the second locking hole 263 are provided in a one-to-one correspondence. The connector passes through the first locking hole 211 and the second locking hole 263 to connect the mounting plate 210 and the second assembly frame 260. In this embodiment, the diameter of the first locking hole 211 is smaller than the diameter of the second locking hole 263, thereby enabling precise adjustment of the mounting plate 210 and the second assembly frame 260 in the second direction Y while achieving a stable connection between the two.

[0030] In this embodiment, two sealing components 220 are spaced apart on the mounting plate 210. These two sealing components 220 respectively seal the volume button and power button on the side wall of the mobile phone. The two sealing components 220 have the same structure; here, we will describe the structure of one as an example: The sealing component 220 includes a frame 221 and a sealing ring 222. The frame 221 is disposed on the mounting plate 210, and the sealing component 220 is disposed inside the frame 221 and can surround the button to be sealed. In different embodiments, the number and placement of the sealing components 220 can be adaptively adjusted according to actual usage requirements; this invention does not impose specific limitations in this regard.

[0031] The sealing mechanism 200 in this embodiment further includes an extension bracket 240, one end of which is connected to the mounting plate 210 and the other end is connected to the displacement sensor 230, so that the displacement sensor 230 is oriented toward the button to be sealed.

[0032] The button sealing structure in this embodiment also includes a control mechanism, and the displacement sensor 230 and the push driver 250 are respectively connected to the control mechanism. In actual production and processing, operators can use the control mechanism to adjust the structure in real time, thereby improving the flexibility of the equipment. Parameters can also be preset through the control mechanism, thereby improving the automation level of the equipment.

[0033] Example 2:

[0034] This embodiment provides a mobile phone production system, which includes the button sealing structure described in Embodiment 1.

[0035] In summary, the button sealing structure and mobile phone production system described in this utility model connect the sealing mechanism 200 to one side of the production line via the movable installation mechanism 100, and its actual working position can be adjusted horizontally via the sliding connector 130. The sealing mechanism 200 can be positioned by the displacement sensor 230 to ensure that the sealing component 220 can seal the button under the action of the push driver 250. Compared with conventional sealing technologies at present, this application has the advantages of precise positioning, adjustable position, flexible use, wide applicability, and ease of operation, providing a new design concept for button sealing technology.

[0036] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
