[0002] With the rapid development of mobile communication technology, the pace of mobile phone product updates and iterations has accelerated. Different models of mobile phones have different casing sizes, which places higher demands on the flexibility and precision of the mobile phone assembly process.

[0003] In the mobile phone assembly process, the fixed positioning of the mobile phone casing is a key process to ensure assembly accuracy. Stable and reliable fixing fixtures can effectively prevent the mobile phone casing from shifting or shaking during the assembly process, ensuring the accuracy of component assembly, thereby improving overall assembly efficiency and product qualification rate.

[0004] Currently, most conventional mobile phone assembly fixtures are dedicated structures, designed for specific mobile phone models. These fixtures are difficult to adapt to different sizes and specifications of mobile phone casings. When switching between different mobile phone models on the production line, the corresponding fixtures need to be disassembled and replaced, increasing tooling changeover time, reducing production efficiency, and raising equipment maintenance costs. Meanwhile, while some general-purpose fixtures attempt to adapt to multiple specifications, they suffer from insufficient clamping stability. During clamping, they often only clamp two sides of the casing, and in actual assembly, the casing is still prone to shifting under external forces, affecting assembly accuracy and work efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fixed fixture for mobile phone assembly, which aims to improve the problems of poor adaptability of the fixed fixture in the prior art, high efficiency and low cost caused by the need to replace the fixture when switching models, and unstable clamping of the general-purpose fixture, which makes the shell easily shift under external force during clamping, affecting the assembly accuracy.

[0018] 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.

[0019] Reference Figures 1-2 The present invention provides an embodiment of a mobile phone assembly fixture, including an assembly table 1. The assembly table 1 is placed directly on the ground and can provide support for other components and provide a support platform for mobile phone assembly. The upper part of the assembly table 1 is provided with a positioning mechanism, which can quickly clamp and position mobile phone shells of different specifications to ensure stability during the assembly process and provide a guarantee for subsequent assembly accuracy and work efficiency.

[0020] Reference Figure 1 , Figure 3 , Figure 4The positioning mechanism includes a clamping assembly 3, which is used to clamp and fix the mobile phone casing. The clamping assembly 3 includes a connecting plate 31, which is positioned above the assembly table 1. The lower surface of the connecting plate 31 does not contact the upper surface of the assembly table 1, which can reduce friction during processing. An electric push rod 4 is provided on the front surface of the connecting plate 31. The electric push rod 4 is existing technology and can be implemented by those skilled in the art. The electric push rod 4 can extend and retract flexibly. The electric push rod 4 is an XTXL series model and can stop at any position within the extension and retraction range. It can be used with a manual or remote control system. A sliding plate 32 is slidably connected through the front surface of the connecting plate 31. The sliding plate 32 serves as a guide and power transmission plate. The sliding plate 32 moves back and forth. A connecting block 33 is fixedly connected to the front surface of the sliding plate 32, which guides the connecting block 33. The front end of the output shaft of the electric push rod 4 is fixedly connected to the rear surface of the connecting block 33. The electric push rod 4 can change the distance between the connecting block 33 and the connecting plate 31 by extending and retracting its output shaft to accommodate mobile phone casings of different widths. A rotating shaft 34 is elastically connected to the inner wall of the connecting block 33 via a torsion spring 35. The torsion spring 35 has an elastic reset function, which can provide a continuous elastic force to the rotating shaft 34, ensuring that the rotating shaft 34 maintains its initial position when there is no external force intervention. The rotating shaft 34 is rotatably connected to the upper surface of the connecting block 33, and the rear surface of the rotating shaft 34 is fixedly connected to... A slider 36 is connected to the inner wall of the connecting block 33, which has a guide groove 37. The slider 36 and the guide groove 37 work together to guide and limit the rotation angle of the rotating shaft 34, ensuring that the rotating shaft 34 rotates only within the set range and avoiding excessive rotation that could cause clamping failure. The guide groove 37 is arc-shaped with a span of 80°. The slider 36 slides and fits into the inner wall of the guide groove 37. A drive plate 38 is fixedly connected to the upper surface of the rotating shaft 34. The rotating shaft 34 acts as a rotational transmission component, transmitting its rotational motion to the drive plate 38. The drive plate 38 is L-shaped, and clamping blocks 39 are rotatably connected to the rear end and left end of the upper surface of the drive plate 38. The L-shaped drive plate 38 can... The two clamping blocks 39 in different directions move simultaneously, achieving synchronous clamping of different sides of the phone, improving the stability and comprehensiveness of the clamping. The outer wall of the clamping block 39 is made of rubber, which can ensure the stability of the clamping and avoid damaging the surface of the phone shell. Multiple sets of rotating shaft 34, torsion spring 35, slider 36, guide groove 37, drive plate 38, and clamping block 39 are provided. Multiple sets of rotating shaft 34, torsion spring 35, slider 36, guide groove 37, drive plate 38, and clamping block 39 are symmetrically distributed on the connecting block 33 and the rear end of the connecting plate 31. The clamping component 3 is provided in two sets, which are symmetrically distributed on the left and right with the center line of the assembly table 1 as the axis. This can achieve synchronous clamping of the four corners of the phone shell.

[0021] Reference Figures 1-2The positioning mechanism also includes a guide component 2, which is used to drive the clamping component 3 to adjust its position in the horizontal direction. The guide component 2 includes a motor 21, which is a power source and is existing technology that can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case. The motor 21 is set on the right surface of the assembly table 1. The output shaft of the motor 21 is fixedly connected to a bidirectional threaded rod 22. The bidirectional threaded rod 22 passes through and is rotatably connected to the inner wall of the assembly table 1. The outer wall of the bidirectional threaded rod 22 is threadedly connected to a guide plate 23. The bidirectional threaded rod 22 has a bidirectional thread structure. When it rotates, it can drive the guide plates 23 on both sides to move relative to each other or in opposite directions at the same time, thereby realizing the adjustment of the distance between the two clamping components 3 to adapt to mobile phone workpieces of different lengths. The guide plate 23 passes through and is slidably connected to the upper surface of the assembly table 1. The upper surface of the guide plate 23 is fixedly connected to the lower surface of the connecting plate 31.

[0022] Working principle: When the tooling is working, the spacing between the front and rear drive plates 38 is first adjusted according to the width specifications of the mobile phone shell to be assembled. During the adjustment, the electric push rod 4 is activated. The output shaft of the electric push rod 4 extends and retracts, driving the slide plate 32 to slide back and forth along the connecting plate 31. The slide plate 32 synchronously drives the connecting block 33 fixed to it to move, thereby driving the drive plates 38 on the connecting block 33 to move synchronously until the spacing between the front and rear drive plates 38 is adapted to the width of the mobile phone shell, and then the electric push rod 4 is stopped.

[0023] The phone casing is then placed on the support platform of assembly table 1. The motor 21 is then started to drive the bidirectional threaded rod 22 to rotate. The guide plate 23 will move closer under the thread drive. The guide plate 23 will then drive the two sets of clamping components 3 fixed to it to move synchronously. Gradually, the clamping block 39 will come into contact with the surface of the phone casing. The force generated by the contact will push the rotating shaft 34 to rotate. The slider 36 at the rear end of the rotating shaft 34 will slide along the arc-shaped guide groove 37. At the same time, the torsion spring 35 will be twisted to generate an elastic restoring force until the two sets of clamping blocks 39 press the adjacent two sides of the phone casing respectively to complete the stable clamping. Then the assembly work begins.

[0024] After assembly, start motor 21 drives bidirectional threaded rod 22 to rotate in the opposite direction, thereby separating guide plate 23 and two sets of clamping components 3, releasing the clamping state on the mobile phone shell, and the assembled mobile phone shell can be taken out. If it is necessary to assemble mobile phone shells of different specifications, the above steps can be repeated.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
