Description

Technical Field

[0001] This utility model relates to a positioning device for processing mobile phone back covers, belonging to the field of mobile phone back cover processing technology. Background Technology

[0002] In the mobile phone manufacturing process, the back cover is a critical component, not only protecting internal components but also directly affecting the product's appearance and user experience. The precision of the back cover's processing is crucial to the overall assembly effect of the phone, including the overall sealing, structural fit, and aesthetic integrity, all of which are closely related to the quality of the back cover's processing. Currently, mobile phone back cover materials are increasingly diversifying towards ceramics, glass, and other materials, and designs are constantly innovating, such as using curved structures and fine textures. This places higher demands on the positioning devices used to secure the back cover during processing. As fundamental equipment for subsequent back cover processing steps, the positioning device must ensure the back cover is stably fixed to guarantee the smooth progress of subsequent processing; it is an indispensable piece of equipment in the mass production of mobile phone back covers.

[0003] While existing mobile phone back cover positioning devices can achieve basic fixing functions, with common methods including mechanical clamping and vacuum adsorption, they still have significant shortcomings in actual mass production scenarios. Firstly, positioning and disassembly operations rely excessively on manual labor: workers must manually adjust the clamping structure or control the adsorption switch to fix the back cover, and then individually release it after processing. This not only increases labor intensity but can also cause indentations or misalignment of the back cover due to varying operating force. In mass production, manual operation is inefficient, directly impacting overall production progress and resulting in insufficient ease of use for the positioning device. Secondly, given the thinness of mobile phone back covers, existing devices lack suitable retrieval assistance designs: after processing, the back cover is often difficult to remove due to adsorption residue or excessive tightness against the positioning surface. Workers typically need to use auxiliary tools for retrieval, which not only prolongs process transition time but also easily causes edge damage and surface scratches, leading to increased product defect rates and further impacting overall production efficiency. These problems not only reduce the actual effectiveness of the positioning device but also make its performance unsatisfactory. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Example 1

[0024] This utility model provides a positioning device for processing mobile phone back covers.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes a frame 1, a slide groove 2 on the lower side of the frame 1, a limit groove 3 on the upper end of the slide groove 2, and stabilizing grooves 4 on both sides of the frame 1. The inner wall of the slide groove 2 is provided with a connecting structure, which includes an extrusion frame 5. An adjustment frame 6 is fixed to one end of the extrusion frame 5. A slider 7 is slidably connected to the outer surface of the extrusion frame 5. A spring 8 is fixed to the upper end of the slider 7. A fixing rod 9 is fixed to the rear side of the slider 7. Two connecting frames 10 are rotatably connected to the outer surface of the fixing rod 9. A stabilizing frame 11 is rotatably connected to the other end of each of the two connecting frames 10. A sliding frame 12 is fixed to one end of each of the two stabilizing frames 11. A clamp 13 is detachably installed on the adjacent sides of the two sliding frames 12 by bolts.

[0026] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that the outer surface of the extrusion frame 5 is slidably connected to the inner wall of the slide groove 2, which runs through the front side of the frame 1. The outer surface of the adjustment frame 6 is rotatably connected to the inner wall of the slide groove 2, and one end of the adjustment frame 6 is fixed to the middle of the extrusion frame 5. The inclined surface of the extrusion frame 5 is slidably connected to the inclined surface of the slider 7. The outer surface of the slider 7 is slidably connected to the inner wall of the limiting groove 3, which runs through the rear side of the frame 1. The rear side of the slider 7 is fixed to the front end of the fixing rod 9. The outer surface of the fixing rod 9 is slidably connected to the inner wall of the limiting groove 3, and the outer surface of the fixing rod 9 is rotatably connected to... At the near ends of the two connecting frames 10, the two connecting frames 10 are rotatably connected to the outer surfaces of the two stabilizing frames 11. One end of the two stabilizing frames 11 is fixed to one end of the two sliding frames 12. The outer surfaces of the two sliding frames 12 are slidably connected to the inner walls of the two stabilizing grooves 4. The middle part of each sliding frame 12 is hollowed out. The two clamps 13 are installed on the near sides of the two sliding frames 12 by bolts. Both ends of the frame body 1 are fixed with connecting ears 17. The middle of the two connecting ears 17 is provided with a reserved hole. The two connecting ears 17 are arranged opposite to each other.

[0027] In use, this utility model is operated by manually pressing the adjusting frame 6, which in turn moves the pressing frame 5, which is fixedly connected to the adjusting frame 6, along the slide groove 2. During the sliding process, the pressing frame 5 applies a pressing force by cooperating with the inclined surface of the slider 7 through its own inclined surface. Since the slider 7 is constrained by the limiting groove 3 and can only move vertically, it will move upward under the action of the pressing force. When the slider 7 moves upward, it compresses the spring 8 fixed at its upper end and drives the fixed rod 9 fixed at the rear to move upward synchronously. The fixed rod 9 can move along the limiting groove 3 through the frame 1.

[0028] The upward-moving fixed rod 9, through the connecting frame 10 rotatably connected to its outer surface, transmits force through the two stabilizing frames 11, causing the two sliding frames 12 to move away from each other along the corresponding stabilizing grooves 4. When the two sliding frames 12 move, they will cause the clamps 13, which are detachably installed on their adjacent sides by bolts, to separate synchronously. After sufficient space is formed between the two clamps 13, the back cover of the mobile phone to be processed is placed in it.

[0029] Then, releasing the pressure on the adjusting bracket 6 releases the compressed spring 8, causing the slider 7 to return to its vertical position. During the return process, the slider 7 sequentially moves the pressing bracket 5 and the adjusting bracket 6 back to their initial positions. Simultaneously, the force is transmitted in the opposite direction through the fixing rod 9, causing the two sliding brackets 12 and the connected clamp 13 to move closer to each other, automatically clamping and fixing the back cover of the phone. The entire operation only requires pressing the adjusting bracket 6 to achieve clamping, achieving a convenient clamping effect and bringing convenience to the operator, thereby improving the ease of use of the positioning device.

[0030] Example 2

[0031] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An automatic lifting function has been added based on Embodiment 1;

[0032] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that a support rod 14 is fixed at the middle of the upper end of the slider 7, and a rubber pad 15 is fixed at the upper end of the support rod 14. A through hole 16 is opened in the middle of the frame 1, and the through hole 16 passes through the middle of the upper end of the limiting groove 3. The lower end of the support rod 14 is fixed at the middle of the upper end of the slider 7, and the upper end of the support rod 14 is fixed at the middle of the lower end of the rubber pad 15. The outer surface of the rubber pad 15 is in contact with the inner wall of the through hole 16.

[0033] In use, this utility model is operated by manually pressing the adjusting frame 6, which drives the extrusion frame 5, which is fixedly connected to the adjusting frame 6, to slide along the slide groove 2. During the sliding process, the extrusion frame 5 applies extrusion force by cooperating with the inclined surface of the slider 7 through its own inclined surface; since the slider 7 is constrained by the limiting groove 3 and can only move vertically, it will move upward under the action of extrusion force.

[0034] When slider 7 moves upward, it compresses the spring 8 fixed at its upper end and simultaneously drives the support rod 14 fixed at its upper middle part to move upward. As the support rod 14 moves upward, the rubber pad 15 fixed at its upper end extends out from the through hole 16 in the middle of the frame 1. This process automatically lifts the back cover upward after the phone back cover is processed, making it convenient for staff to directly remove the back cover without having to pry it off or use tools, thus achieving an automatic lifting effect when removing the back cover.

[0035] Simultaneously, the upward movement of slider 7 will also cause the fixed rod 9 fixed on the rear side to move upward synchronously. The fixed rod 9 can move along the limit groove 3 on the frame 1. The upward-moving fixed rod 9 is connected to the connecting frame 10 through the outer surface. The force is transmitted through the two stabilizing frames 11, causing the two sliding frames 12 to move along the corresponding stabilizing grooves 4 in a direction away from each other. This will cause the clamps 13 that are detachably installed on the adjacent sides by bolts to separate synchronously, thereby unlocking the processed mobile phone back cover and achieving the effect of automatic lifting for disassembly. This effectively improves the processing efficiency and thus enhances the performance of the positioning device.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
