Description

Technical Field

[0001] This disclosure relates to the field of sapphire lens processing technology, and in particular to a combined sapphire lens cleaning fixture. Background Technology

[0002] Sapphire, as a high-end crystal material, is primarily used in consumer electronics as display lenses, such as smartwatch crystals, heart rate monitor lenses, and smartphone cover glass. To ensure good visual quality, the edges of these sapphire lenses need to be polished to enhance clarity and achieve optimal visual performance. Currently, sapphire polishing fixtures are mostly made of resin. During processing, the special brushes of the polishing equipment, combined with diamond polishing paste, cause significant wear and tear on the polishing fixture, leading to frequent replacements and high processing costs. Therefore, there is an urgent need to design a new type of polishing fixture that can reduce processing costs. Summary of the Invention

[0003] To solve the above-mentioned technical problems, or at least partially solve them, this disclosure provides a combined sapphire lens cleaning fixture, which can effectively reduce processing costs.

[0004] To achieve the above objectives, this utility model provides a combined sapphire lens scanning fixture, comprising: A base having several first through holes and several positioning holes; A cover plate having a plurality of second through holes and third through holes, wherein the number of second through holes is the same as the number of first through holes, and the center positions of the second through holes correspond to those of the first through holes; The cover plate is bonded to the base through the third through hole; The cover plate has several positioning openings; the number of positioning openings is the same as the number of positioning holes and their positions correspond to each other.

[0005] Optionally, the positioning hole includes a fourth through hole and a platform surface.

[0006] Optionally, a first annular groove is formed at the edge of the first through hole.

[0007] Optionally, a second annular groove is formed between the first through hole and the first annular groove.

[0008] Optionally, a first annular platform exists between the first through hole and the second annular groove; a second annular platform exists between the first annular groove and the second annular groove.

[0009] Optionally, the first through hole has two first strip grooves and two second strip grooves at its edge.

[0010] Optionally, the first strip groove and the second strip groove are perpendicular to each other.

[0011] Optionally, the first strip groove and the second strip groove extend through the first annular platform and the second annular platform.

[0012] Optionally, both the base and the cover are made of resin.

[0013] The technical solution provided in this disclosure has the following advantages compared with the prior art: This disclosure provides a modular sapphire lens cleaning fixture. By attaching a cover plate to the base, the cleaning process only wears down the cover plate, not the base. The cover plate can be directly replaced when worn to a certain extent, thus avoiding excessive wear on the base. Furthermore, the processing cost of the cover plate (approximately 30 yuan each) is far lower than the processing cost of the base (approximately 600 yuan each). Therefore, this modular sapphire lens cleaning fixture significantly reduces the processing cost of sapphire lens cleaning. Attached Figure Description

[0017] It should be noted that, since the components on the base of the combined sapphire lens scanning fixture provided in this disclosure are structurally identical and numerous, therefore, Figure 3Only one of the multiple repeating parts is shown in the image. Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0020] like Figures 1-3 As shown, this disclosure provides a combined sapphire lens scanning fixture, characterized in that it includes: The base 1 and the cover plate 2 are provided. The base 1 has several first through holes 11 and several positioning holes 12. The cover plate 2 has several second through holes 21 and third through holes 22. The number of second through holes 21 is the same as the number of first through holes 11, and the center positions of the second through holes 21 and the first through holes 11 are corresponding. The cover plate 2 is bonded to the base 1 through the third through holes 22. The cover plate 2 has several positioning holes 23; the number of positioning holes 23 is the same as the number of positioning holes 12 and their positions correspond to each other.

[0021] Specifically, the base 1 can be a cylindrical structure, and is fixed to the polishing device using screws through several positioning holes 12. The number and corresponding positions of the positioning ports 23 and positioning holes 12 allow for quick placement of the cover plate 2 onto the corresponding position on the base 1. The number of first through holes 11 and second through holes 21 are the same, and their centers correspond, for placing the sapphire lens. Simultaneously, the vacuum adsorption device of the polishing device adsorbs the sapphire lens onto the base 1 through the first through holes 11. The cover plate 2 is bonded to the base 1 through the third through holes 22. After placing the cover plate on the base 1, glue can be applied along the edge of the third through holes 22, and the combined action of multiple third through holes 22 can fix the cover plate 2 onto the base 1.

[0022] By attaching a cover plate 2 to the base 1, wear and tear on the base 1 can be effectively reduced during the polishing process. After multiple processing cycles, the cover plate can be replaced directly, while the base can be retained and reused, thereby reducing processing costs.

[0023] In practical use, the base 1 is fixed on the polishing device. The cover plate 2 is placed on the base 1 at a specific position by aligning the positioning port 23 with the positioning hole 12. Glue is applied along the edge of the third through hole 22 to fix the cover plate 2 on the base 1. After the glue dries, the sapphire lens is placed in the second through hole 21. Then, the vacuum adsorption device of the polishing device is turned on to adsorb the sapphire lens onto the base 1. Finally, the polishing device is started, and the sapphire lens is polished with a special brush and polishing paste.

[0024] In some embodiments, the positioning hole 12 includes a fourth through hole 121 and a platform surface 122.

[0025] Specifically, the positioning hole 12 is a stepped through hole. This design allows the top of the screw of the fixed base 1 to be fully recessed into the positioning hole 12 on the base 1, preventing the brush from getting stuck between the screw and the base during processing, thus effectively improving the stability of processing.

[0026] like Figure 1 As shown, a first annular groove 13 is formed at the edge of the first through hole 11. This arrangement enhances the adsorption force of the vacuum adsorption device of the polishing equipment on the sapphire lens during processing.

[0027] In some embodiments, a second annular groove 14 is formed between the first through hole 11 and the first annular groove 13.

[0028] In some embodiments, a first annular platform 15 exists between the first through hole 11 and the second annular groove 14; a second annular platform 16 exists between the first annular groove 13 and the second annular groove 14.

[0029] In some embodiments, the first through hole 11 has two first strip grooves 17 and two second strip grooves 18 at its edge. By opening the grooves, the adsorption force of the vacuum adsorption device of the light-scanning equipment can be increased, avoiding the sapphire lens from shifting position due to insecure fixing during processing, and increasing the stability of processing.

[0030] In some embodiments, the first strip groove 17 and the second strip groove 18 are perpendicular to each other. In this way, the adsorption force of the vacuum adsorption device can be applied evenly to the sapphire, thereby enhancing the stability of the vacuum adsorption device in adsorbing the sapphire lens.

[0031] In some embodiments, the first strip groove 17 and the second strip groove 18 extend through the first annular platform 15 and the second annular platform 16.

[0032] In some embodiments, both the base 1 and the cover plate 2 are made of resin.
