Description

Technical Field

[0001] The utility model relates to the technical field of electronic device assembly, in particular to an anti-scratching assembly jig. Background Technique

[0002] With the continuous innovation of technology, people's requirements for the performance, quality and cost of various electronic devices are getting higher and higher. The structural performance of various electronic devices is becoming more and more advanced, and the process requirements are also getting stricter. Among them, smart phones have become an essential tool in people's lives. Mobile phones can not only be used for ordinary calls, but also for a variety of leisure and entertainment, and even various learning, etc., which can all be achieved through mobile phones. With the popularization of mobile phones, people's requirements for mobile phones are also getting higher and higher. The development of mobile phones towards thin and light makes their thickness thinner and thinner, but the process has become more and more complex.

[0003] The audio sealing effect of mobile phones is related to issues such as mobile phone sound quality, waterproof and dustproof performance, and prevention of echo. However, with the development of mobile phones towards thin and light, the overall size of the mobile phone is reduced, the area of the small board is reduced, and the sound quality requirements result in a need for a certain length of the sound output channel, which limits the position of the MIC. The position of the MIC needs to be installed forward. The antenna on the small board has a grounding requirement, and there are protruding ribs on the side board of the small board to strengthen the overall structure and play a role in support and protection. The ribs may be distributed directly opposite the MIC, and the overall structure is relatively compact. During installation, the small board and the USB need to be obliquely inserted and installed on the middle frame. Among them, a foam or silicone material for sealing is provided directly below the small board opposite the MIC. During the oblique insertion installation process, the small board will scratch the foam or silicone material for sealing. The scratching of the foam or silicone material for sealing will cause the audio data to deteriorate, resulting in a poor user experience, requiring rework, and affecting production capacity and efficiency.

[0004] Therefore, it is necessary to provide an anti-scratching assembly jig that can effectively avoid the problem of oblique insertion and scratching. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an anti-scratching assembly jig that can effectively avoid the problem of oblique insertion and scratching.

[0006] To achieve the above purpose, the utility model provides an anti-scratching assembly jig, which is applicable to electronic devices.

[0028] In order to elaborate on the technical content and structural features of the present utility model in detail, the following further explanations are provided in conjunction with the embodiments and with reference to the drawings.

[0029] Please refer to Figures 1 to 4 , the present utility model provides an anti-scratch assembly jig 100, which is applicable to an electronic device 200. The electronic device 200 includes a small board 102 and a middle frame 101. An audio seal 103 for sealing is provided on the middle frame 101. When the small board 102 is obliquely inserted and assembled on the middle frame 101, it will scratch the audio seal 103 on the middle frame 101, resulting in wear of the audio seal 103 and deterioration of audio data, and further affecting the sound quality, etc. The audio seal 103 can be a sealing foam or a silicone material, etc. These audio seals 103 are easily scratched and worn. By assembling the small board 102 and the middle frame 101 in the anti-scratch assembly jig 100, it is possible to effectively prevent the audio seal 103 from being scratched and worn, effectively avoid rework, and improve efficiency. The anti-scratch assembly jig 100 includes a base 10, and an accommodation cavity 11 for accommodating the middle frame 101 is provided on the base 10. The assembly of the middle frame 101 and the small board 102 is carried out in the accommodation cavity 11. Among them, a material stop 20 is adjustably provided on the outer side of the accommodation cavity 11, and the specific position of the material stop 20 can be adjusted appropriately according to actual usage needs. One end of the material stop 20 can move at multiple angles and can extend into the middle frame 101 in the accommodation cavity 11, and the material stop 20 extending into the middle frame 101 covers the audio seal 103. When the small board 102 is obliquely inserted and pre-assembled on the middle frame 101, the material stop 20 is blocked between the audio seal 103 and the small board 102, which can effectively prevent the small board 102 from scratching the audio seal 103. The middle frame 101 pre-assembled with the small board 102 is removed from the accommodation cavity 11 so that the material stop 20 is separated from the middle frame 101. When the middle frame 101 pre-assembled with the small board 102 is taken out of the accommodation cavity 11, the material stop 20 is separated from the middle frame 101 at the same time.

[0030] Compared with the prior art, when the small board 102 of the electronic device 200 is assembled onto the middle frame 101, the anti-scratching assembly jig 100 of the present utility model can effectively prevent the small board 102 from scratching the audio seal 103 on the middle frame 101, making the overall audio effect of the assembled electronic device 200 more stable and reliable. The anti-scratching assembly jig 100 includes a base 10, and a receiving cavity 11 for receiving the middle frame 101 is formed on the base 10. The middle frame 101 of the electronic device 200 is placed in the receiving cavity 11, and the small board 102 is obliquely inserted and installed onto the middle frame 101 in the receiving cavity 11. The receiving cavity 11 can effectively position the middle frame 101. Among them, a baffle 20 is adjustably arranged on the outer side of the receiving cavity 11. The baffle 20 can be arranged on the base 10, or the baffle 20 is arranged on other structures. One end of the baffle 20 can move at multiple angles and can extend into the middle frame 101 in the receiving cavity 11 and cover the audio seal 103. It can be understood that one end of the baffle 20 is arranged on the outer side of the receiving cavity 11, and the other end can be bent and moved at multiple angles so as to completely cover the audio seal 103, thereby effectively protecting the audio seal 103 from being scratched by the small board 102 when the small board 102 is obliquely inserted and installed onto the middle frame 101, which may affect the sealing performance and sound quality effect of the audio seal 103. Due to the setting requirements of the overall machine structure, the small board 102 needs to be obliquely pre-installed in the middle frame 101. The baffle 20 is blocked between the audio seal 103 and the small board 102, which can prevent the small board 102 from scratching the audio seal 103 on the middle frame 101 during installation. The middle frame 101 pre-installed with the small board 102 is removed from the receiving cavity 11 so that the baffle 20 is separated from the middle frame 101. The small board 102 is pre-installed onto the middle frame 101 through a snap position. Before screwing, the baffle 20 can be easily pulled out. When the middle frame 101 is taken out of the receiving cavity 11, it can be separated from the baffle 20 at the same time without other processes, which is convenient to operate and has high efficiency. The anti-scratching assembly jig 100 of the present utility model has a simple structure and is easy to use. It can effectively prevent the small board 102 from scratching the audio seal 103 on the middle frame 101 during the assembly process, making the overall sound quality effect of the assembled electronic device 200 better.

[0031] Please refer to Figures 1 to 4, in some alternative embodiments, an adjustment plate 30 is provided on the base 10. The adjustment plate 30 is used to mount and adjust the material baffle 20, and the adjustment plate 30 is located outside the accommodation cavity 11. Among them, an installation groove 31 for mounting the material baffle 20 is formed in the adjustment plate 30. One end of the material baffle 20 is arranged in the installation groove 31, and the other end of the material baffle 20 can extend into the middle frame 101 in the accommodation cavity 11 and cover the audio seal 103. Specifically, one end of the material baffle 20 is fixed in the installation groove 31, or one end of the material baffle 20 is detachably arranged in the installation groove 31. The other end of the material baffle 20 can be flexibly moved at multiple angles, so that the material baffle 20 can cover the audio seal 103 of the middle frame 101 at a suitable position and angle according to actual installation needs.

[0032] Please refer to Figure 6 , in some alternative embodiments, the installation groove 31 has an inwardly concave structure. The installation groove 31 includes a first cavity 311 and a second cavity 312 that communicate with each other. Among them, the second cavity 312 is inclined downward at a certain angle and communicates with the first cavity 311. The second cavity 312 is located on the side of the adjustment plate 30 close to the accommodation cavity 11. The material baffle 20 is placed in the first cavity 311 and is inclined downward under the guidance of the second cavity 312, so as to better extend into the lower accommodation cavity 11, and thus can better extend into the middle frame 101 and cover the audio sealant. On the other hand, the installation groove 31 has a first cavity opening 32 and a second cavity opening 33 that communicate with each other. The first cavity opening 32 is formed on the top surface of the adjustment plate 30 and communicates with the first cavity 311 and the second cavity 312. The second cavity opening 33 is formed on the side surface of the adjustment plate 30 and communicates with the second cavity 312. That is, the first cavity opening 32 is formed on the top surface of the installation groove 31, and the second cavity opening 33 is formed on the side surface of the installation groove 31. It can be understood that the formation of the first cavity opening 32 facilitates the taking, placing and fixing of the material baffle 20 and the fixing block 40 in the installation groove 31. The formation of the second cavity opening 33 facilitates the extension of the material baffle 20 from the installation groove 31 into the accommodation cavity 11.

[0033] Please refer to Figures 1 to 4 and Figure 7, in some alternative embodiments, a fixing block 40 for positioning the material blocking member 20 is also detachably disposed in the installation groove 31. The fixing block 40 includes a first positioning portion 41 that fits with the first cavity 311 and a second positioning portion 42 that fits with the second cavity 312. The second positioning portion 42 is inclined and disposed at one end of the first positioning portion 41. It can be understood that the fixing block 40 cooperates with the installation groove 31 to position one end of the material blocking member 20 in the installation groove 31. Among them, a fixing portion 43 is further disposed between the first positioning portion 41 and the second positioning portion 42. The fixing portion 43 is bent between the first positioning portion 41 and the second positioning portion 42, and the fixing portion 43 fits with the bent portion between the first cavity 311 and the second cavity 312, which can effectively fix the material blocking member 20 in the installation groove 31. Pressing the fixing block 40 can fix one end of the material blocking member 20 in the installation groove 31, which is convenient to operate, stable and reliable, and can also effectively guide the material blocking member 20 to better cover the audio sealing member 103.

[0034] Please refer to Figure 3 , Figure 5 and Figure 6, in some alternative embodiments, the adjusting plate 30 is provided with adjusting holes 34, and the base 10 is provided with fixing holes 13 that cooperate with the adjusting holes 34. By passing fixing members such as screws through different parts of the adjusting holes 34 and installing them in the fixing holes 13, the position of the adjusting plate 30 and the material blocking member 20 thereon on the base 10 can be adjusted. It can be understood that the adjusting holes 34 are in a long strip shape. By cooperating different parts of the adjusting holes 34 with the fixing holes 13, the installation position of the adjusting plate 30 can be adjusted, and further the position of the material blocking member 20 relative to the middle frame 101 can be adjusted. Also, by adjusting the position of the material blocking member 20 in the installation groove 31, the material blocking member 20 can better extend into the middle frame 101 and cover the audio sealing member 103. In this embodiment, the material blocking member 20 is a strip-shaped mylar sheet, and the thickness of the mylar sheet is between 0.05 mm and 0.50 mm. The mylar sheet has high insulation strength, high withstand voltage, resistance to moisture, gas, high heat and chemical substances, and also has characteristics such as low shrinkage rate, not being easily embrittled and wear-resistant. Moreover, the mylar sheet can be bent at multiple angles to be adjusted to a suitable use position according to actual needs. Of course, a wear-resistant non-trace adhesive tape, a thin film sheet, etc. can also be used to replace the mylar sheet for material blocking, as long as the material blocking member 20 can cover the audio sealing member 103 to prevent the small board 102 from scraping the audio sealing member 103 when being obliquely inserted into the middle frame 101 and can be easily detached from the middle frame 101. On the other hand, the base 10 is provided with a notch 12 communicating with the accommodating cavity 11, and the notch 12 is used to facilitate the taking and placing of the middle frame 101 in the accommodating cavity 11. That is, the middle frame 101 can be more conveniently placed in or taken out of the accommodating cavity 11 through the notch 12. When taking out the middle frame 101 through the notch 12, the middle frame 101 pre-mounted with the small board 102 is detached from the accommodating cavity 11 and simultaneously detached from the material blocking member 20, and the operation is convenient.

[0035] Such as Figures 1 to 7As shown, the anti-scratching assembly fixture 100 of the present utility model can effectively prevent the small board 102 from scratching the audio seal 103 on the middle frame 101 when the small board 102 of the electronic device 200 is assembled to the middle frame 101, making the overall audio effect of the assembled electronic device 200 more stable and reliable. The anti-scratching assembly fixture 100 includes a base 10, and a receiving cavity 11 for receiving the middle frame 101 is formed on the base 10. The middle frame 101 and the small board 102 of the electronic device 200 are assembled in the receiving cavity 11. Among them, an adjusting plate 30 is adjustably arranged on the outer side of the receiving cavity 11, and a material blocking member 20 is arranged on the adjusting plate 30. The specific position of the material blocking member 20 on the base 10 can be appropriately adjusted through the adjusting plate 30 according to actual use needs. One end of the material blocking member 20 can move at multiple angles and can extend into the middle frame 101 in the receiving cavity 11 and cover the audio seal 103. It can be understood that one end of the material blocking member 20 is arranged on the outer side of the receiving cavity 11, and the other end can be bent and moved at multiple angles so as to completely cover the audio seal 103, thereby effectively protecting the audio seal 103 from being scratched by the small board 102 when the small board 102 is obliquely inserted and installed in the middle frame 101, which may affect the sealing performance and sound quality effect of the audio seal 103, etc. Due to the setting requirements of the overall machine structure, the small board 102 needs to be obliquely pre-installed in the middle frame 101. The material blocking member 20 is blocked between the audio seal 103 and the small board 102, which can prevent the small board 102 from scratching the audio seal 103 on the middle frame 101 during installation. The middle frame 101 pre-installed with the small board 102 is separated from the receiving cavity 11 so that the material blocking member 20 is separated from the middle frame 101. The small board 102 is pre-installed in the middle frame 101 through a buckle position. Before screwing, the material blocking member 20 can be easily pulled out. When the middle frame 101 is taken out of the receiving cavity 11, it can be separated from the material blocking member 20 at the same time without other processes, with convenient operation and high efficiency. The anti-scratching assembly fixture 100 of the present utility model has a simple structure and is easy to use. It can effectively prevent the small board 102 from scratching the audio seal 103 on the middle frame 101 during the assembly process, making the overall sound quality effect of the assembled electronic device 200 better.
