Technical Field

[0001] This application relates to the technical field of mobile phone manufacturing, and specifically proposes a mobile phone mid-frame clamp. Background Technology

[0002] Currently, the mobile phone manufacturing industry is highly competitive, and the production costs of mobile phone components need to be strictly controlled. However, in the traditional processing of plastic mid-frames, the gap between the fixture and the mid-frame is relatively large, and the limiting is not stable enough. Moreover, the long side of the plastic mid-frame is relatively soft, and when the mid-frame is chamfered, it is easy for the mid-frame to deform or vibrate, which can cause over-milling, tool marks, or uneven chamfering at the chamfered area, resulting in unqualified products.

The base and pressure plate hold at least a portion of the structure of the mobile phone mid-frame. The base and / or pressure plate have limiting posts along the length direction of the mobile phone mid-frame. The limiting posts correspond to the openings. The distance between the edge of the pressure plate and the flange of the mobile phone mid-frame is 'a', and satisfies 0.03mm≤a≤0.05mm.

[0017] To make the embodiments of this application clearer, they will be described below in conjunction with the accompanying drawings. It is to be understood that the content mentioned below is only a partial embodiment of this application, while the complete list of all embodiments is provided. Therefore, other embodiments obtained based on the following embodiments without any inventive effort all fall within the protection scope of this application.

[0018] It should be understood that the terminology used herein is for the purpose of describing specific embodiments only and is not intended to impose strict limitations on the technical solutions unless the context clearly indicates otherwise. For example, the use of "a," "an," and "the" to modify a feature does not preclude the possibility that the feature may be plural in other embodiments.

[0019] It should be understood that the terms "comprising," "including," and "having" are open-ended, indicating the presence of the stated features but not excluding the possibility of other features in the embodiment. Similarly, the use of terms such as "first," "second," etc., to describe multiple features only indicates the distinction between one feature and another, and such terms do not imply order or sequence unless explicitly stated in the context.

[0020] It should be understood that, unless the context clearly indicates otherwise, the terms "setup," "connection," and "installation" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integrated connection; they can refer to a direct connection or an indirect connection via a medium. Those skilled in the art will understand the specific meaning of these terms in this document based on the specific circumstances.

[0021] In addition, for ease of description, the text will use terms of spatial relative relationship to describe the position of one feature relative to another feature, such as "inner", "outer", "end", "side", "upper", "middle", "lower", "high", "low", "axial", "circumferential", "radial", "horizontal", "vertical", "first direction", "second direction", etc. It can be understood that the spatial relative relationship between two features should include other specific situations besides those shown in the accompanying drawings of the specification.

[0022] The embodiments of this application will now be described with reference to the accompanying drawings.

[0023] Reference Figure 1 and Figure 2The embodiments of this application propose a mobile phone mid-frame clamp for clamping a mobile phone mid-frame 10. The mobile phone mid-frame 10 has an opening on its edge and a flange 101 on its edge. The mobile phone mid-frame clamp includes a base 20 and a pressure plate 30. The base 20 and the pressure plate 30 clamp at least a portion of the structure of the mobile phone mid-frame 10. The base 20 and / or the pressure plate 30 have a limiting post 201 along the length direction X of the mobile phone mid-frame 10. The limiting post 201 corresponds to the opening. The distance between the edge of the pressure plate 30 and the flange 101 of the mobile phone mid-frame 10 is a, and satisfies 0.03mm≤a≤0.05mm.

[0024] In this embodiment, the base 20 and / or the pressure plate 30 are provided with limiting posts 201, which pass through the opening of the mobile phone frame 10, and have a good limiting effect.

[0025] It should be noted that the openings in the phone's mid-frame 10 are designed for assembly or clearance, and the limiting posts 201 on the base 20 and / or pressure plate 30 match the openings, which is a reasonable design. In such cases... Figure 2 In the illustrated embodiment, there are multiple limiting posts 201, each corresponding to a multiple opening. Since the long side of the phone frame 10 is relatively large and more prone to vibration, the multiple limiting posts 201 are spaced at least along the length direction X of the phone frame 10 to ensure the limiting of the long side of the phone frame 10. It is understandable that some of the multiple limiting posts 201 can also be spaced along the width direction Y of the phone frame 10 to limit the width side, which is also a preferable implementation method.

[0026] Furthermore, according to the experiment, when the distance 'a' between the edge of the pressure plate 30 and the flange 101 of the mobile phone frame 10 is greater than 0.05mm, the mobile phone frame 10 vibrates more when chamfering or other processing steps are performed, which can easily lead to overmilling, tool marks, or uneven chamfering, resulting in a low product yield. When the distance 'a' between the edge of the pressure plate 30 and the flange 101 of the mobile phone frame 10 is less than 0.03mm, the processing tool is more likely to interfere with the pressure plate 30, affecting the processing progress. It also makes the area covered by the pressure plate 30 of the mobile phone frame 10 larger and the pressure tighter, making it more difficult to remove the mobile phone frame 10 after processing.

[0027] Therefore, the assembly gap 'a' between the edge of the pressure plate 30 and the flange 101 of the mobile phone frame 10 should be appropriate, that is, 0.03mm≤a≤0.05mm. This further ensures that the mobile phone frame 10 reduces vibration during chamfering or other processing steps, avoids overmilling, tool marks, or uneven chamfering, and improves product yield. At the same time, it can prevent interference between the processing tool and the pressure plate 30, which would affect the processing progress, and also prevent difficulties in removing the mobile phone frame 10 after processing. For example, 'a' can be any one of 0.03mm, 0.04mm, and 0.05mm or fall within the range of any two of these values.

[0028] Reference Figure 1 and Figure 2 In some embodiments, the mobile phone frame clamp further includes a driving member 40, which drives the pressure plate 30 to press against the base 20. In some embodiments, the mobile phone frame clamp further includes a support frame 50, which is connected to the base 20 and has an accommodating space, within which a portion of the driving member 40 is located. In some embodiments, there are multiple driving members 40, which are arranged along the length direction X of the mobile phone frame 10. In some embodiments, the base and the pressure plate 30 are provided with corresponding clearance holes, and the driving member 40 has a power output rod 401 that moves along the thickness direction Z of the mobile phone frame 10. The end of the power output rod 401 is provided with a block 402, which drives the block 402 to pass through the clearance holes of the base and the pressure plate 30 and rotates the block 402 to press against the side of the pressure plate 30 facing away from the base.

[0029] In this embodiment, the support frame 50 is located on the side of the base 20 facing away from the pressure plate 30, and provides a space for the drive component 40. This design is reasonable and reduces the overall space occupation, while leaving space above the pressure plate 30 for the installation of other mechanisms, such as a blower mechanism for cleaning chamfered debris.

[0030] Specifically, the clearance hole on the base 20 can be a round hole or a strip hole. The block 402 is detachably connected to the power output rod 401. That is, when the clearance hole on the base 20 is a round hole, the power output rod 401 passes through the round hole before the block 402 is installed. The clearance hole on the pressure plate 30 is a strip hole, and the cross-sectional shape of the block 402 is approximately the same as the strip hole. That is, the block 402 can pass through the clearance hole on the pressure plate 30 from bottom to top along the thickness direction Z of the mobile phone frame 10. Then, the power output rod 401 drives the block 402 to rotate around the axial direction, for example, by 90°. At this time, the block 402 cannot pass through the strip hole. The power output rod 401 drives the block 402 to press down against the pressure plate 30 to clamp the mobile phone frame 10.

[0031] Furthermore, multiple drive components 40 are arranged along the length X of the phone frame 10, enabling comprehensive pressure to be applied to all parts of the pressure plate 30, resulting in a more uniform pressing effect. Understandably, the power output rods 401 of each drive component 40 pass through areas on the phone frame 10 with clearance structures, and the guide rods on the base 20 are similarly designed; further details will not be elaborated upon hereafter.

[0032] In some embodiments, refer to Figure 1 The pressure plate 30 has inclined surfaces 303 around its four perimeters.

[0033] In this embodiment, the inclined surface 303 can work in conjunction with the blower mechanism mentioned above to prevent the edge of the pressure plate 30 from blocking the airflow. The airflow blown out by the blower mechanism reaches the chamfered part of the mobile phone frame 10 along the inclined surface 303, which has a guiding effect, thereby effectively cleaning up the debris during the chamfering process.

[0034] In some embodiments, refer to Figure 1 The pressure plate 30 includes a first plate 301 and a second plate 302. The first plate 301 is connected to the second plate 302. The second plate 302 presses against the mobile phone frame 10. The hardness of the second plate 302 is less than that of the first plate 301.

[0035] In this embodiment, the second plate 302 directly contacts the mobile phone frame 10. The second plate 302 has low hardness to avoid damaging the mobile phone frame 10. Optionally, the first plate 301 is made of metal, such as aluminum, and the second plate 302 is made of acrylic.

[0036] Reference Figure 1 and Figure 2 In some embodiments, the pressure plate 30 has a handle 304 on the side facing away from the seat 20. In some embodiments, the seat 20 has a guide rod, and the pressure plate 30 has a through hole that matches the guide rod. In some embodiments, the edge of the pressure plate 30 has a notch 305.

[0037] In this embodiment, multiple notches 305 are spaced apart along the edge of the pressure plate 30. After the mobile phone frame 10 is processed, the pressure plate 30 can be pried up through the notches 305 using other tools. Furthermore, the pressure plate 30 can be lifted manually using the handle 304. In addition, the guide rod on the base 20 passes through the through hole on the pressure plate 30 to achieve the positioning of the pressure plate 30.

[0038] In particular, the term "and / or" in this application should be understood as follows: In the first case, the term “and / or” between the first subject and the second subject includes any of the following meanings: (1) only the first subject; (2) only the second subject; and (3) both the first subject and the second subject.

[0039] In the second case, the term "and / or" between the last two of three or more subjects means including at least one of the subjects. For example, "first subject, second subject and / or third subject" has the same meaning as "first subject and / or second subject and / or third subject", specifically including the following combinations: (1) only the first subject; (2) only the second subject; (3) only the third subject; (4) first subject and second subject and no third subject; (5) first subject and third subject and no second subject; (6) second subject and third subject and no first subject; and (7) first subject, second subject and third subject; Furthermore, the character " / " in this application indicates that the objects before and after it are in an "or" relationship.

[0040] Furthermore, although the embodiments of this application have been described above in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the concept of this application, and such modifications and variations all fall within the scope of protection of this application.
