[0026] Please refer to Figures 1 - 3As shown in the figure, in this specific embodiment, a cover plate polishing device includes: a positioning component 1, the positioning component 1 includes a terminal portion 11 and a positioning portion 12, the positioning portion 12 is provided with a first groove 121, the first groove 121 is used to accommodate the cover plate 3 to be processed, and the terminal portion 11 is arranged at one end of the positioning portion 12 away from the first groove 121; a polishing component 2, the polishing component 2 includes a base 21 and a polishing leather 22, the base 21 is provided with a polishing groove 211 facing the positioning component 1, the polishing leather 22 is located in the polishing groove 211, and the cover plate to be processed is polished in the polishing groove 211. By providing the first groove 121 on the positioning portion 12 to accommodate and limit the cover plate 3 to be processed, the polishing accuracy and the high-quality requirements of the cover plate are ensured. And further, by providing the base 21 with the polishing groove 211 and the polishing leather 22 arranged in the polishing groove 211 on the polishing component 2, the complexity of the polishing operation is reduced and the polishing accuracy is improved. And by providing the terminal portion 11 on the positioning component 1, the terminal portion 11 is used to receive an external force, so that the positioning component 1 can tightly press the cover plate 3 to be processed against the polishing leather 22, so as to better polish the cover plate 3 to be processed. It can be understood that in this application, the cover plate 3 to be processed is limited and polished through the cooperation of the positioning component 1 and the polishing component 2, and the cover plate 3 to be processed can be polished on a large scale, reducing the complexity of the polishing operation and meeting the actual production needs.

[0027] In this embodiment, the base 21 includes an inclined surface 212 and a bottom surface 213, the inclined surface 212 and the bottom surface 213 enclose the polishing groove 211, and the polishing leather 22 is attached to the inclined surface 212. By designing the contact surface of the polishing groove 211 with the cover plate 3 to be processed as the inclined surface 212, it is convenient for the inclined surface part or the periphery of the cover plate 3 to be processed to contact the polishing leather 22, and the polishing accuracy is improved. It should be noted that for the cover plates of existing electronic products, mainly 2.5D screen cover plates are used, and their characteristics are that the central part is flat, while the edge has a certain arc-shaped cover plate, that is, mainly the periphery of the cover plate needs to be polished; by designing part of the polishing groove 211 as the inclined surface 212, it is convenient to install the cover plate 3 to be processed in the polishing groove 211, and then better polish it to improve the polishing accuracy.

[0028] In this embodiment, the included angle between the inclined surface 212 and the bottom surface 213 is A, and 10° ≤ A ≤ 80°. The included angle A between the inclined surface 212 and the bottom surface 213 determines the opening angle of the polishing groove. Different included angles A can be determined according to the size and shape of the cover plate 3 to be processed, so that the polishing device meets different requirements and improves the application scenarios.

[0029] In this embodiment, a positioning groove 111 is formed in the terminal portion 11 away from the positioning portion 12. The terminal portion 11 is mainly used to receive an external acting force, so that the cover plate 3 to be processed is tightly clamped between the positioning assembly 1 and the polishing assembly 2, preventing the cover plate 3 to be processed from tilting on the polishing leather 22 and ensuring the polishing accuracy. For example, a pressure rod is provided on an existing polishing device. The pressure rod is inserted into the positioning groove 111, and the pressure rod provides a pressure to tightly press the positioning assembly 1 against the polishing assembly 2.

[0030] In this embodiment, a second groove 122 is formed on one side of the positioning portion 12 away from the first groove 121, and the terminal portion 11 is disposed in the second groove 122. It can be understood that the terminal portion 11 and the positioning portion 12 can be of an integral structure or a split structure. Preferably, the terminal portion 11 and the positioning portion 12 adopt a split structure, and the two adopt a detachable connection method, which is convenient for the operator to replace different terminal portions 11 or positioning portions 12 according to the actual situation when the cover plate polishing device faces polishing devices or cover plates 3 to be processed of different sizes or types, improving the application scenarios of the cover plate polishing device and reducing the replacement cost of the cover plate polishing device. Of course, when the terminal portion 11 and the positioning portion 12 adopt an integral structure, it is convenient for the processing of the positioning assembly 1, reducing the processing procedures and the manufacturing cost of the positioning assembly 1.

[0031] Based on the above solution, the material of the positioning portion 12 is any one of bakelite material, acrylic material and epoxy resin material. This can avoid scratching the cover plate 3 to be processed, thereby preventing product scrapping and improving the product yield.

[0032] Based on the above solution, the terminal portion 11 is made of cemented carbide material. Considering that the terminal portion 11 is mainly used to receive an external acting force, using cemented carbide material can improve the wear resistance of the terminal portion 11, thereby improving the service life of the cover plate polishing device.

[0033] In this embodiment, the polishing leather 22 has an annular structure. The annular polishing leather 22 is convenient to be better installed in the polishing groove 211. At the same time, considering that the polishing leather 22 mainly contacts the cover plate 3 to be processed on its side, and its middle part does not participate in the polishing effect, the annular structure can reduce the usage area of the polishing leather 22 and the usage cost of the cover plate polishing device. Preferably, the polishing leather 22 has an open annular structure, which is convenient to install the polishing leather 22 on the base 21.

[0034] In this embodiment, a plurality of through holes 221 are formed in the polishing leather 22. Firstly, the plurality of through holes 221 can allow the polishing liquid to flow into the polishing groove 211 (directly below the cover plate 3 to be processed) through the through holes, making the polished cover plate 3 more uniform and bright; secondly, it can increase the grinding force of the polishing leather 22 and improve the processing efficiency.

[0035] In this embodiment, a threaded rod 23 is connected to one end of the base 21 away from the polishing tank 211. The threaded rod 23 is used to fixedly arrange the base 21 on the polishing equipment. The threaded rod 23 is arranged at the bottom of the base 21 and is connected and fixed to the polishing equipment through the threaded rod 23 to ensure the installation stability of the base 21. At the same time, the polishing equipment drives the base 21 to rotate through the threaded rod 23 to ensure the stable rotation of the base 21, which is convenient for improving the polishing accuracy of the to-be-processed cover plate 3.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
