Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessory processing, and in particular to a device for trimming the edge of the bottom plate of a mobile phone wireless charging box. Background Technology

[0002] With the widespread adoption of wireless charging for smartphones, the market demand for wireless charging cases is growing. Wireless charging technology applies the technology of wireless charging to mobile phones, providing a comfortable and convenient experience of simply placing the phone down to charge. It also solves many problems associated with traditional charging methods, such as the inconvenience of connecting wires and the hassle of forgetting to bring a charging cable. Furthermore, the working principle of wireless charging technology is to use electromagnetic induction to charge the phone. When the device is placed on the charging base, a changing magnetic field is generated inside the base. The coil inside the charging receiver senses this changing magnetic field, thereby generating current and transferring electrical energy to the device's battery for charging.

[0003] A wireless charging case is an electronic device that integrates wireless charging technology. It allows devices such as mobile phones and Bluetooth headsets to be placed on it and automatically begin charging without the need for a charging cable. A wireless charging case typically consists of a charging base and a charging receiver. During its production, the processing quality of the base plate edges becomes a significant issue. Traditional finishing processes rely heavily on manual hand-held polishing tools, which is not only inefficient and time-consuming but also makes it difficult to guarantee consistent finishing precision. Insufficiently secure fixing of the base plate can easily lead to uneven edges, affecting the product's assembly accuracy and appearance. Therefore, we propose a wireless charging case base plate edge finishing device to address these problems. Utility Model Content

[0022] Please see Figure 1-4 In this utility model, a device for trimming the bottom edge of a wireless charging box includes a trimming support 1. A platform 2 is fixedly connected to the upper surface of the trimming support 1. A side baffle 3 is fixedly connected to the left side of the platform 2 and the upper surface of the trimming support 1. Main support seats 14 are fixedly connected to both the front and back of the trimming support 1. A main telescopic cylinder 15 is fixedly connected to the upper surface of each main support seat 14. A side clamping plate 16 is fixedly connected to the output end of each main telescopic cylinder 15. A secondary support seat 17 is fixedly connected to the left side of the side baffle 3 and the left side of the trimming support 1. A secondary telescopic cylinder 18 is fixedly connected to the inner wall of the secondary support seat 17. A U-shaped connecting frame 19 is fixedly connected to the output end of the secondary telescopic cylinder 18. The outer surface of the U-shaped connecting frame 19 is fixedly... Connected to a T-shaped positioning component 20, the U-shaped connecting frame 19 and the T-shaped positioning component 20 are moved up and down by the auxiliary telescopic cylinder 18, which can accurately position the bottom plate of the wireless charging box and determine its initial position on the platform 2. This provides an accurate reference for subsequent edge trimming operations, ensuring trimming accuracy and avoiding edge trimming that does not meet requirements due to positional deviation. The main telescopic cylinder 15 pushes the side clamping plate 16 to move, clamping the bottom plate of the charging box from both sides. Combined with the blocking effect of the side baffle 3, the bottom plate can be firmly fixed during the trimming process, effectively ensuring stability during trimming. This can effectively meet the various needs of the edge trimming process of the bottom plate of the wireless charging box, improve processing quality and efficiency, and ensure the smooth progress of production.

[0023] The upper surface of the trimming support 1 has two guide grooves 21, and a sliding connecting plate 22 is slidably connected inside each guide groove 21. The upper surface of each sliding connecting plate 22 is fixedly connected to the outer surface of the side clamping plate 16. When adjusting the position of the side clamping plate 16, the sliding connecting plate 22 can slide in the guide groove 21 to prevent the side clamping plate 16 from tilting. The bottom surface of the trimming support 1 is fixedly connected to a bottom frame 4. A servo motor 5 is fixedly connected to the inner wall of the bottom frame 4. A lead screw 6 is fixedly installed at the output end of the servo motor 5 through a coupling. A nut sleeve 7 is threadedly connected to the outer surface of the lead screw 6. Two transmissions are fixedly connected to the outer surface of the nut sleeve 7. The top of each transmission rod 8 passes through the trimming support 1 and extends to the top of the trimming support 1. The tops of the two transmission rods 8 are fixedly connected to an electric guide rail 9. A slider 11 is slidably connected inside the electric guide rail 9. A tool motor 12 is fixedly connected to the upper surface of the slider 11. A rotating tool 13 is fixedly connected to the output end of the tool motor 12. The lead screw 6 is driven to rotate by the servo motor 5, which drives the nut sleeve 7, transmission rods 8 and electric guide rail 9 to achieve vertical position adjustment. The slider 11 inside the electric guide rail 9 can also drive the tool motor 12 and rotating tool 13 to move horizontally, which can flexibly trim the edge of the charging box bottom plate.

[0024] The upper surface of the trimming support 1 has two square openings 10, each of which is adapted to the size of the transmission rod 8, making the movement of the transmission rod 8 smoother. The bottom surface of the trimming support 1 is fixedly connected with multiple supporting square columns 23, with gaps left between the two supporting square columns 23 and the two transmission rods 8 respectively. The supporting square columns 23 provide a solid support for the device and do not affect the movement of the transmission rod 8. The upper surface of the platform 2 and the outer surface of the two side clamping plates 16 are provided with protective pads 24. The protective pads 24 can prevent scratches and other damage to the surface of the charging box bottom plate during clamping, and can also play a certain buffering role to avoid damage to the workpiece due to excessive clamping force.

[0025] The working principle of this utility model is as follows:

[0026] Place the device in a stable position, and place the bottom plate of the wireless charging box to be repaired on the platform 2. First, start the auxiliary telescopic cylinder 18 to move the U-shaped connecting frame 19 up and down. The movement of the U-shaped connecting frame 19 can move the T-shaped positioning piece 20 down to initially position the bottom plate of the wireless charging box. Then, start the main telescopic cylinder 15 to push the side clamping plate 16 to move. The mutual movement of the two side clamping plates 16 clamps the two sides of the bottom plate of the wireless charging box. Combined with the blocking effect of the side baffle 3, the bottom plate can be firmly fixed during the repair process. Then, start the servo motor 5 to rotate the lead screw 6, which moves the nut sleeve 7 and the transmission rod 8 left and right under the action of the thread. The movement of the transmission rod 8 moves the electric guide rail 9 and the tool motor 12 to a position close to the bottom plate of the wireless charging box. At the same time, start the tool motor 12 to rotate the rotating tool 13. The rotating tool 13 is used to repair the fixed bottom plate of the wireless charging box.
