[0002] Shielding covers are widely used in electronic equipment to shield against electromagnetic interference and protect internal components for stable operation. The smoothness of their surface directly affects the product's assembly accuracy, appearance quality, and electromagnetic shielding performance; therefore, polishing is a critical process in shielding cover production. With the rapid development of the electronics industry, market demand for shielding covers continues to rise, placing higher demands on the efficiency, stability, and economy of polishing processes.

[0003] Traditional polishing equipment is often complex in structure, and the entire polishing process is too reliant on manual labor, which makes it difficult to guarantee the polishing quality of the product and may result in some shielding covers not being polished properly.

[0004] Furthermore, existing polishing equipment generally lacks effective station detection and linkage control mechanisms. Even when the shielding cover is not accurately positioned, the polishing wheel will continue to spin idly. This idling not only wastes electricity and polishing consumables, increasing production costs, but also accelerates the wear of the polishing wheel, shortens the equipment's lifespan, and reduces the overall economic efficiency of the processing.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Please refer to the attached diagram. A shield polishing machine has a polishing table 1 as its core support. All key operating components are directly or indirectly mounted on the polishing table 1, ensuring structural stability and operational coordination during operation. As the core execution component for polishing, the polishing disc 2 is rotatably connected to the upper surface of the polishing table 1. Its power source is a servo motor. Through the precise transmission of the servo motor, the polishing disc 2 can achieve stable speed adjustment to adapt to the polishing needs of shields of different materials. To further enhance the comprehensiveness of the polishing operation, an adjustment component 3 is mounted on the side above the polishing table 1. The core function of this component is to mount the polishing wheel 5 and flexibly adjust its position, thereby adapting to the polishing of shields of different specifications. Specifically, a first motor 4 is fixedly connected to the top of the adjustment component 3. The output shaft of the first motor 4 is connected to the polishing wheel 5. By driving the polishing wheel 5 to rotate at high speed through the first motor 4, and cooperating with the adjustment component 3 to adjust the relative position of the polishing wheel 5 and the polishing table 1, multi-directional precise polishing of the shield on the polishing disc 2 can be achieved.

[0030] To automate the feeding and transfer of shielding covers, conveying components 6 are symmetrically arranged on both sides of the polishing table 1. The two sets of conveying components 6 are symmetrically distributed, enabling simultaneous batch feeding of shielding covers to be polished, thus improving the equipment's operating efficiency. Notably, each set of conveying components 6 is equipped with a robotic arm component 7 near the polishing disc 2. This robotic arm component 7, as the core component connecting the conveying and polishing processes, primarily functions to precisely grasp and place the shielding cover placement component 8, which carries the shielding covers to be polished, onto the polishing disc 2, completing the automated feeding process without manual intervention. This improves operating efficiency and ensures the accuracy of the feeding position.

[0031] The specific structure and working principle of the adjustment component 3 will be described in detail below. The adjustment component 3 is fixedly connected to the polishing table 1 via the first base frame 9. The first base frame 9 is the supporting foundation of the entire adjustment component 3, and a sliding table 10 is slidably connected on it. The sliding direction of the sliding table 10 can achieve displacement closer to or further away from the rotation center of the polishing disc 2, thereby driving the polishing wheel 5 to achieve radial position adjustment. To drive the sliding table 10 to slide stably, a second motor 11 is fixedly connected to the bottom of the first base frame 9, and a first screw 12 is rotatably connected to the first base frame 9. The sliding table 10 and the first screw 12 are connected by a threaded connection, and the first screw 12 is connected to the second motor 11 for transmission. When the second motor 11 is started, it drives the first screw 12 to rotate synchronously. With the help of the threaded transmission force, the sliding table 10 is driven to slide linearly along the first base frame 9, thereby realizing the radial position adjustment of the polishing wheel 5.

[0032] To achieve horizontal adjustment of the polishing wheel 5, a corresponding drive and transmission structure is also installed on the sliding table 10. A third motor 13 is fixedly connected to the sliding table 10 as the power source for horizontal adjustment. A transverse platform 14 is slidably connected to the sliding table 10, serving as the direct mounting carrier for the first motor 4 and the polishing wheel 5. To drive the transverse platform 14, a second screw 15 is threadedly connected to the sliding table 10. The transverse platform 14 and the second screw 15 are also threadedly connected, and the second screw 15 is driven by the third motor 13. When the third motor 13 starts, it drives the second screw 15 to rotate, causing the transverse platform 14 to slide horizontally along the sliding table 10 via threaded transmission. Since the first motor 4 is fixed to the top of the transverse stage 14 and the polishing wheel 5 is rotatably connected to the bottom of the transverse stage 14, the sliding of the transverse stage 14 will synchronously drive the polishing wheel 5 to achieve lateral position adjustment. Combined with the radial adjustment function of the sliding stage 10, the polishing wheel 5 can achieve multi-dimensional position adjustment on the horizontal plane to meet complex polishing needs.

[0033] The two sets of conveying components 6 have identical structures, both using the conveying platform 16 as their supporting base. A conveyor belt 17 is laid on top of the conveying platform 16, serving as the core component for material conveying. The conveyor belt 17 is driven by a conveyor motor 18 fixed to the bottom of the conveying platform 16. During operation, the conveyor motor 18 starts and drives the conveyor belt 17 to rotate cyclically. The shielding cover placement component 8 is placed directly on the conveyor belt 17, utilizing the friction of the conveyor belt 17 to achieve smooth conveying and accurately transporting the shielding cover to be polished within the gripping range of the robotic arm component 7, preparing it for subsequent automated loading.

[0034] The robotic arm assembly 7 is designed with precise gripping and stable transfer as its core features. It is fixedly connected to the top of the polishing table 1 via a fixed bracket 19, which provides stable support for the entire robotic arm assembly 7. A gripping arm 20 is horizontally slidably connected to the top of the fixed bracket 19, allowing the gripping position to switch between the gripping position and the position above the polishing disc 2. To enable the lifting and lowering movement of the gripping arm 20, an electric telescopic rod 21 is fixedly connected to its bottom. A gripper 22 is connected to the bottom of the electric telescopic rod 21. The extension and retraction of the electric telescopic rod 21 drives the gripper 22 to move up and down, and the opening and closing of the gripper 22 completes the gripping and releasing of the shielding cover placement assembly 8.

[0035] To drive the picking arm 20 to slide along the top of the fixed bracket 19, a fourth motor 23 is fixedly connected to the fixed bracket 19. The picking arm 20 slides by the driving force provided by the fourth motor 23, and its sliding trajectory precisely covers two key positions above the conveying component 6 and above the polishing disc 2. During operation, after the shielding cover placement component 8 is conveyed to the designated position, the fourth motor 23 drives the picking arm 20 to slide above the conveying component 6. The electric telescopic rod 21 extends, causing the gripper 22 to descend. The gripper 22 closes to grab the shielding cover placement component 8. Then, the electric telescopic rod 21 retracts, and the fourth motor 23 drives the picking arm 20 to slide above the polishing disc 2. The electric telescopic rod 21 extends again, and the gripper 22 opens to place the shielding cover placement component 8 on the polishing disc 2, completing the entire transfer process.

[0036] To adapt to different ground conditions in various working scenarios and ensure the overall horizontal stability of the polishing machine, a targeted design was implemented at the bottom of the polishing table 1. Specifically, the bottom of the polishing table 1 is equipped with adjustable support feet 24 via a threaded connection. Rotating the adjustable support feet 24 allows for height adjustment, thereby adjusting the levelness of the polishing table 1 and preventing uneven ground from affecting polishing accuracy. Furthermore, for convenient movement and transport, casters 25 are fixedly connected to the bottom of the polishing table 1. When movement is required, the casters 25 can be used to easily push the equipment to the designated location. After movement, the adjustable support feet 24 can be used to support and fix the equipment, balancing flexibility and stability.

[0037] To further improve the positioning accuracy of the shielding cover placement assembly 8 on the polishing disc 2 and prevent displacement during polishing that could affect the polishing quality, a support ring 26 is provided on the polishing disc 2. This support ring 26 rotates synchronously with the polishing disc 2, providing a stable support for the shielding cover placement assembly 8. Several locking holes 27 are provided on the support ring 26. The size of these locking holes 27 is adapted to the bottom of the shielding cover placement assembly 8 to limit its position on the polishing disc 2, ensuring its stability during polishing. Simultaneously, a signal receiver 28 is provided at the bottom of each locking hole 27. This signal receiver 28 forms a linkage control relationship with the first motor 4. When the signal receiver 28 in the corresponding locking hole 27 directly below the first motor 4 is subjected to pressure from the shielding cover placement assembly 8, a control signal is triggered, starting the first motor 4 to drive the polishing wheel 5 to rotate, initiating the polishing operation. This achieves automated triggering of the polishing process and enhances the intelligence level of the equipment.

[0038] The shielding cover placement assembly 8, as the core component carrying the shielding cover, directly affects the transport stability and polishing safety of the shielding cover. This assembly includes a housing 29, which features a hollow structure, reducing overall weight and providing space for internal components. Several limiting grooves 30 are provided on the top of the housing 29. These grooves 30 are shaped to fit the shielding cover and are used to place the shielding cover to be polished. The dimensions of the limiting grooves 30 are slightly larger than the dimensions of the shielding cover, facilitating insertion and removal while preventing excessive shaking of the shielding cover during transport.

[0039] To improve the polishing effect, a vibration motor 31 and a lithium battery 32 are installed inside the housing 29. The lithium battery 32 provides stable power to the vibration motor 31. The vibration motor 31 and the lithium battery 32 are electrically connected through a controller, which can adjust the vibration frequency and start / stop status of the vibration motor 31. When the shielding cover placement assembly 8 is moved from the conveyor belt 17 to the position of the slot 27, if there is a positional deviation, the vibration motor 31 will turn on, and under the action of vibration, the shielding cover placement assembly 8 will enter the slot 27.

[0040] To facilitate removal of the shielding cover after polishing, the housing 29 is made of a flexible material with excellent flexibility and resilience. To ensure polishing precision, the size of the limiting groove 30 is precisely fitted to the shielding cover, further enhancing the polishing effect. However, after polishing, the shielding cover may become stuck inside the limiting groove 30 and difficult to remove. This can be addressed by manually bending the housing 29 to slightly deform the limiting groove 30, widening the opening and allowing the shielding cover to be easily removed. This convenient operation avoids damage to the shielding cover and effectively improves the efficiency of the unloading process. Simultaneously, the vibration of the vibration motor 31 also significantly improves the efficiency of shielding cover removal. In most cases where removal is impossible, turning on the vibration motor 31 allows for easy removal.
