Description

Technical Field

[0001] This utility model relates to the field of fixing mechanisms, and in particular to a suspended mobile phone steel sheet fixing mechanism. Background Technology

[0002] Mobile phone steel sheets are key metal components inside mobile phones. They are usually made of stainless steel or carbon steel through precision stamping. They have high strength, good heat dissipation and electromagnetic shielding performance. They are mainly used as mid-frame brackets, battery covers or internal structural components, playing a role in supporting, fixing and protecting core components, ensuring that the mobile phone structure is stable, thin and durable.

[0003] Existing suspended mobile phone steel sheet fixing mechanisms typically employ a simple method of placing the steel sheet directly on a suspended conveyor. Their structural design is relatively simple and lacks flexible and adjustable positioning and clamping units. When faced with various specifications of mobile phone steel sheets of different sizes, shapes, or hole layouts, it is difficult to achieve accurate positioning and reliable clamping, which can easily lead to displacement, shaking, or even falling off of the steel sheet during the conveying process, causing considerable inconvenience.

[0016] 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.

[0017] This utility model provides, for example Figures 1-3 The suspended mobile phone steel sheet fixing mechanism shown includes a hinge 1, a fixing frame 2, a fixing plate 3, a positioning mechanism 4, and a limiting mechanism 5. The hinge 1 is fixedly connected to both sides of the fixing frame 2. The hinge 1 on both sides of the fixing frame 2 is the key component for its suspension tooling and external suspension conveying. It acts as a flexible connection point, allowing the entire mechanism to be suspended under the track of the conveyor line. Through the rotation characteristics of the hinge 1, the mechanism can adapt to the turns and undulations of the conveying path and run smoothly. Meanwhile, it ensures that the mechanism maintains the preset working posture during dynamic conveying, thereby achieving continuous and stable assembly line operation of mobile phone steel sheets. The fixing plate 3 is fixedly connected to the outer wall of the fixing frame 2. The positioning mechanism 4 is set on the fixing plate 3 for positioning the mobile phone steel sheets. The limiting mechanism 5 is set on the fixing plate 3 for limiting the displacement of the mobile phone steel sheets at multiple points. The adjustable limiting mechanism 5 can limit the mobile phone steel sheets of different specifications, improving the versatility of the fixing mechanism. At the same time, the suction cup 41 in the positioning mechanism 4 can be used to adsorb and fix the mobile phone steel sheets. The fixing method of the suction cup 41 can ensure the surface quality of the steel sheets without damage, while ensuring accurate positioning, effectively avoiding scratches or displacement that may be caused by traditional mechanical clamping, improving the production yield and operational stability, and making it easy to use.

[0018] Specifically, the positioning mechanism 4 includes a suction cup 41, a sleeve 42, a piston 43, and a pull rod 44. The suction cup 41 is fixedly installed at equal intervals on the top of the fixing plate 3. An air groove communicating with the suction cup 41 is opened inside the fixing plate 3. The sleeve 42 is fixedly connected to the bottom of the fixing plate 3. The piston 43 is slidably inserted into the inner cavity of the sleeve 42. One end of the pull rod 44 is fixedly connected to the piston 43, and the other end of the pull rod 44 is slidably inserted into the sleeve 42. The piston 43 can be pulled to slide inside the sleeve 42 by the pull rod 44, thereby generating negative pressure in the air groove inside the fixing plate 3. The suction cup 41 can be used to adsorb and fix the mobile phone steel sheet. The negative pressure adsorption generated by the evenly distributed suction cup 41 avoids surface scratches, indentations, or deformation that may be caused by traditional mechanical clamping. Adsorption and release can be quickly completed by simply pulling the pull rod 44, simplifying the operation steps and significantly improving the line change efficiency between different specifications of products and the overall production efficiency.

[0019] Furthermore, the positioning mechanism 4 also includes a positioning rod 45, a compression spring 46, and a limiting ring 47. A positioning groove is provided on the pull rod 44, and the positioning rod 45 is slidably inserted into the inner cavity of the positioning groove. An inclined surface is provided at the top of the positioning rod 45, and the end of the compression spring 46 is fixedly connected to the positioning rod 45. The compression spring 46 always provides a stable elastic force to the positioning rod 45. By utilizing the inclined surface provided on the positioning rod 45, the vertical force on the inclined surface can be converted into a horizontal force during the pulling process, so that the positioning rod 45 can extend and retract on its own during the pulling process, thereby positioning and locking the pull rod 44 and maintaining the suction force of the suction cup 41, so that the suction cup 41 can fix the mobile phone steel piece. The inner wall of the sleeve 42 is fixedly connected to the limiting ring 47. The limiting ring 47 is used to limit the position of the piston 43. The limiting ring 47 limits the displacement of the piston 43 and prevents it from entering the interior of the air groove, thus maintaining the stability of the piston 43's movement.

[0020] Specifically, the limiting mechanism 5 includes a screw 51, a limiting plate 52, and a handle 53. The top of the fixed plate 3 has grooves at equal intervals. The end of the screw 51 is rotatably inserted into the inner wall of the groove. The limiting plate 52 is located inside the groove. The limiting plate 52 and the screw 51 form a screw drive. The handle 53 is fixedly connected to one end of the screw 51. The outer wall of the handle 53 has anti-slip texture. The handle 53 can drive the screw 51 to rotate in both directions, thereby driving the limiting plate 52 to move back and forth in the horizontal direction under the limitation of the inner wall of the groove, thus limiting the mobile phone steel sheets of different specifications.

[0021] Furthermore, the outer wall of the limiting plate 52 is fixedly connected with an anti-collision pad 54, which is made of rubber. The rubber anti-collision pad 54 has good elasticity and cushioning performance, and can absorb collision energy when the limiting plate 52 comes into contact with the mobile phone steel sheet, effectively preventing the hard limiting plate 52 from causing scratches, indentations or abrasions to the surface of the mobile phone steel sheet, thereby ensuring the appearance quality of the product.

[0022] 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.
