[0033] Working principle and usage process of this utility model:

[0034] In use, place the phone back cover to be polished on the shelf 311 on the base 31 of the processing table 3 for easy access during operation. Check and confirm that all motors (first motor 11, second motor 52, third motor 623, fourth motor 626, fifth motor 43) and electric slides (first electric slide 21, second electric slide 22, third electric slide 23) are in normal working condition and that the power connection is correct. Then, start the first motor 11 under the turntable 32 to put the turntable 32 into a ready-to-work state. Rotate the turntable 32 to the appropriate position manually or automatically, aligning the corresponding clamping component 4 with the phone back cover to be processed. Start the fifth motor 43 in the clamping component 4 to drive... The second lead screw 42 rotates, causing the clamping rods 44 to slide within the slide groove 411 and move closer or further apart until the inner support clamps the phone back cover. Once the phone back cover is securely clamped, the turntable 32 can continue to rotate to the polishing position. Then, based on the material of the phone back cover and the polishing requirements, a suitable polishing head 61 is selected. By adjusting the third motor 623 in the assembly 62, the mounting plate 621 can be rotated, thereby replacing the polishing head 61 to adapt to different polishing needs. The fourth motor 626 in the lifting assembly 624 is activated, driving the first lead screw 627 to rotate, causing the connecting rod 628 to slide up and down within the opening 632 of the housing 625, thereby causing the fixing ring 629 and the mounting ring 622 to move up and down. The grinding head 61 is moved until it aligns with the output end of the second motor 52. Once aligned, the grinding head 61 is securely connected to the second motor 52 using the fixing cylinder 611 and slot 612 at the upper end of the grinding head 61, and the locking block 521 at the output end of the second motor 52. This further activates the first electric slide 21, the second electric slide 22, and the third electric slide 23 in the moving mechanism 2. According to the preset grinding path and parameters, the mounting frame 5 (and its adjusting grinding mechanism 6) is driven to move forward, backward, left, right, and up and down, thereby achieving precise grinding of the phone back cover. During the grinding process, the grinding speed can be adjusted in real time by observing or monitoring the equipment. The device adjusts the pressure and path to ensure polishing quality and efficiency. Once the phone back cover achieves the desired polishing effect, the moving mechanism 2 and the polishing mechanism are stopped, all motors and electric slides are powered off, and the equipment is safely shut down. The clamping assembly 4 is released, and the polished phone back cover is removed from the turntable 32 and placed in the designated position. The above steps are repeated to continue processing the next phone back cover. Through the above usage process, the polishing device for producing phone back covers of this utility model can achieve automated and high-precision polishing of phone back covers, greatly improving production efficiency and product quality. At the same time, its flexible adjustment design of the polishing mechanism 6 and the moving mechanism 2 also adapts to the polishing needs of phone back covers of different models and materials.
