Description

Technical Field

[0001] This application relates to the field of ballast prism processing technology, and more specifically, to a method for processing ballast prisms. Background Technology

[0002] A prism is a commonly used optical element, primarily used in optical systems to change the direction of light rays. It is widely used in electronic products, optical instruments, and other fields. After entering the prism, light undergoes one or more reflections, ultimately exiting at an angle of 90 degrees or 180 degrees.

[0003] As customers demand higher precision in their use of Boro prism products, the deviation of the ridge prism must be within a specified accuracy range, and the ridge prism must be chamfered to prevent chipping. Traditional Boro prism manufacturing methods cannot meet the current precision requirements for chamfering and chipping of the ridge prism, necessitating the development of new processes to satisfy these requirements.

[0004] Therefore, existing technologies still need improvement and development. Summary of the Invention

[0008] The first and second sides of the blank are machined to make the surface shapes of the first and second sides reach the first surface shape reference and be parallel.

[0009] The cylindrical angle between the first side surface, the second side surface, and the bottom surface of the lower plate is used to obtain the part;

[0010] The bottom and top surfaces of the part are machined to make them parallel and achieve a preset size;

[0011] The bottom surface of the part is coated with a glossy adhesive on a first fixture. The first fixture includes a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall that are perpendicular to each other. A first inclined surface is provided between the third sidewall and the fourth sidewall. The first inclined surface forms an angle of 45° with the third sidewall and the fourth sidewall, respectively. The bottom surface glossy adhesive is located at the middle position of the first inclined surface.

[0012] Apply a smooth adhesive to the first sidewall of the first tooling onto the smooth adhesive disc, and mill the cylindrical angle between the first sidewall and the top surface to form a first ridge surface parallel to the first sidewall; apply a smooth adhesive to the second sidewall of the first tooling onto the smooth adhesive disc, and mill the cylindrical angle between the second sidewall and the top surface to form a second ridge surface parallel to the second sidewall, and form a ridge ridge between the first ridge surface and the second ridge surface.

[0013] Chamfer the ridge edge;

[0014] The first and second ridge surfaces are then finely polished.

[0015] Further, the first and second sides of the blank are machined to make their surface shapes meet and parallel to the first surface shape datum. Specific steps include:

[0016] The bottom surface is placed on the cuboid, so that the first side surface is parallel to and higher than the side surface of the cuboid. The first side surface is then sanded and polished.

[0020] The first side is mounted onto the cuboid, making the bottom surface parallel to and higher than the side surface of the cuboid. The bottom surface is then sanded and polished.

[0021] Apply the bottom surface adhesive to the adhesive tray, and then sand and polish the top surface.

[0022] In some embodiments, the bottom surface of the part is coated with a light adhesive onto a first tooling, and the specific steps include:

[0024] The vertical support is placed on the platform, and the side of the V-groove fixture is abutted against the vertical support so that the V-groove opening of the V-groove fixture faces upward.

[0025] The first and second sidewalls of the first tooling are abutted against the V-groove.

[0026] The baffle is coated with a light adhesive on the side of the vertical support body, so that the baffle is perpendicular to the first inclined surface and away from the side of the vertical support body.

[0027] The first side is pressed against the baffle, so that the bottom surface of the blank is coated with adhesive at the middle position of the first inclined surface.

[0028] Further, the first side of the blank is pressed against the baffle, so that the bottom surface of the blank is coated with adhesive at the middle position of the first inclined surface. Specific steps include:

[0029] After applying the photoresist to the part on the first inclined surface, observe the interference fringes on the platform from directly above the part. When the interference fringes are evenly distributed on both sides of the V-groove, the photoresist on the part is located in the middle of the first inclined surface.

[0030] The first sides of the plurality of parts are sequentially and spaced apart by light adhesive to the baffle so that the plurality of parts are all located in the middle position of the first inclined surface.

[0032] Further, the first sidewall of the first tooling is coated with adhesive to the adhesive pad, and the cylindrical angle between the first sidewall and the top surface is milled to form a first ridge surface parallel to the first sidewall. Specific steps include:

[0033] Apply adhesive to the adhesive tray to reinforce the first sidewall;

[0037] Flip the first tooling over, apply the second sidewall adhesive to the adhesive tray, and reinforce it with adhesive.

[0038] The preset dimensions are removed by polishing the cylindrical angle between the second side surface and the top surface at a low speed.

[0042] In some embodiments, the first and second ridge surfaces are finely polished, and the specific steps include:

[0043] Check the width of the ridge edge. If the width exceeds the threshold value of a, first apply a smooth adhesive to the first ridge surface of the ridge edge onto the cuboid, then refine the second ridge surface. Next, apply a smooth adhesive to the second ridge surface of the ridge edge onto the cuboid, and then refine the first ridge surface.

[0064] Please see Figure 1 , Figure 1 A flowchart illustrating the processing method of the Polos prism of this application is shown.

[0065] During the processing, blank 1 is processed, see [reference]. Figure 2The blank 1 is a cuboid, including a top surface 11, a bottom surface 12, and opposing first side surface 13 and second side surface 14. At the same time, the processing will use a first tooling 2. The first tooling 2 includes a first side wall 21, a second side wall 22, a third side wall 23, and a fourth side wall 24 that are perpendicular to each other. A first inclined surface 25 is provided between the third side wall 23 and the fourth side wall 24. The first inclined surface 25 forms a 45° angle with the third side wall 23 and the fourth side wall 24, respectively. That is, the first inclined surface 25 forms a 45° angle with the third side wall 23 and also forms a 45° angle with the fourth side wall 24.

[0066] The processing method for the Boluo prism provided in this application aims to achieve the precision requirements for chamfering and edge chipping of the ridge edge, thus meeting product precision requirements. Specifically, it includes the following steps:

[0067] S100: The first side 13 and the second side 14 of the blank 1 are processed, including grinding and polishing, so that the surface shapes of the first side 13 and the second side 14 reach the first surface shape reference and are parallel.

[0068] S200: Chamfer the cylindrical angle between the first side surface 13, the second side surface 14, and the bottom surface 12 of the lower plate to obtain the part. The finished cylindrical angle is 0.1 + 0.1 × 45°, where 0.1 represents the width of the chamfer (0.1 mm), 0.1 × 45° represents the angle of the chamfer (45 degrees), and the length of the hypotenuse of the chamfer is 0.1 mm. The rest are not chamfered.

[0069] S300: The bottom surface 12 and top surface 11 of the part are machined, including grinding and polishing, so that the top surface 11 and the bottom surface 12 are parallel and reach the preset dimensions.

[0070] S400: Apply gloss adhesive to the bottom surface 12 of the part onto the first tooling 2, see reference. Figure 4 The first tooling 2 includes a first side wall 21, a second side wall 22, a third side wall 23 and a fourth side wall 24 that are perpendicular to each other. A first inclined surface 25 is provided between the third side wall 23 and the fourth side wall 24. The angle between the first inclined surface 25 and the third side wall 23 and the fourth side wall 24 is 45°. The bottom surface 12 is coated with adhesive at the middle position of the first inclined surface 25.

[0071] S500: Apply adhesive to the first sidewall 21 of the first tooling 2 onto the adhesive plate, and mill the cylindrical angle between the first sidewall 13 and the top surface 11 to form a first ridge surface 3 parallel to the first sidewall 21; apply adhesive to the second sidewall 22 of the first tooling 2 onto the adhesive plate, and mill the cylindrical angle between the second sidewall 14 and the top surface 11 to form a second ridge surface 4 parallel to the second sidewall 22, and form a ridge ridge between the first ridge surface 3 and the second ridge surface 4;

[0072] S600: Chamfer the ridge edge;

[0073] S700: The first roof ridge surface 3 and the second roof ridge surface 4 are finely polished to form a prism. (See reference...) Figure 3 Finished Baltic prism.

[0074] In processing blank 1, this method first processes the first side 13, the second side 14, the top surface 11, and the bottom surface 12 of blank 1 to correct its surface shape and side sag. Finally, the ridge is cut, ensuring the processing accuracy of each surface. At the same time, the part is positioned based on the first tooling 2, which can improve the accuracy of processing the ridge surface, reduce the processing difficulty, and also bevel the ridge edges, thus meeting the product design requirements and product accuracy.

[0075] In some embodiments, the first side 13 and the second side 14 of the blank 1 are machined so that the surface shapes of the first side 13 and the second side 14 meet the first surface shape reference and are parallel. Specific steps include:

[0076] The bottom surface 12 of the blank 1 is mounted on the cuboid, so that the first side surface 13 is parallel to and higher than the side surface of the cuboid. The first side surface 13 is then sanded and polished.

[0077] 502. Place the blank 1 on the plate and apply the first side 13 to the plate with gloss adhesive. 502. Seal the first side 13 with the glass plate.

[0078] The second side 14 is sanded and polished. For example, 0.05-0.15 is sanded away, and the disc Δt is controlled to be ≤0.005. After sanding and polishing, the disc is tapped or soaked in acetone and then cleaned once.

[0079] Furthermore, the bottom surface 12 and top surface 11 of the blank 1 are subjected to grinding and polishing to make the top surface 11 and bottom surface 12 parallel and reach the preset dimensions. The specific steps include:

[0080] The first side 13 of the blank 1 is mounted on the cuboid, so that the bottom surface 12 is parallel to and higher than the side surface of the cuboid. The bottom surface 12 is then sanded and polished.

[0081] Place the blank 1 on the plate and apply a light adhesive to the bottom surface 12 on the light adhesive plate. Then, sand and polish the top surface 11.

[0082] This step is the same as the processing method for the first side surface 13 and the second side surface 14 described above. For example, 0.03-0.15 μm is removed by sanding, the disc forming Δt is controlled to be ≤0.005 μm, the speed is low: B = 10⁻⁵, N = 0.2, ΔN = 0.2, and the disc surface shape is ±0.5 μm. After sanding and polishing, the blank 1 is subjected to semi-finished chamfering by tapping or soaking in acetone: the finished angle of the polished surface is 0.1 + 0.1 × 45°, and a second cleaning is performed. At this time, blank 1 with the top surface 11, bottom surface 12, first side surface 13 and second side surface 14 processed can be obtained.

[0083] In some embodiments, the bottom surface 12 of the part is coated with a light adhesive onto the first tooling 2. Specific steps include:

[0084] Provide a second tooling, see below. Figure 5 The second fixture includes a platform 5, a vertical support 6, a V-groove fixture 7 and a baffle 8. The V-groove fixture 7 is provided with a V-groove with a 90° opening angle.

[0085] Set the vertical support 6 on the platform 5, and abut the side of the V-groove fixture 7 against the vertical support 6 so that the V-groove opening of the V-groove fixture 7 faces upward.

[0086] The first sidewall 21 and the second sidewall 22 of the first tooling 2 are abutted against the V-groove;

[0087] On the side of the vertical support body 6, there is a light adhesive baffle 8, so that the baffle 8 is away from the side of the vertical support body 6 and perpendicular to the first inclined surface 25.

[0088] The first side 13 is pressed against the baffle 8, so that the bottom surface 12 of the blank 1 is coated with adhesive at the middle position of the first inclined surface 25.

[0089] In some embodiments, the first side 13 of the part is abutted against the baffle 8, so that the bottom surface 12 is coated with adhesive at the middle position of the first inclined surface 25. Specific steps include:

[0090] After applying the adhesive to the part on the first inclined surface 25, observe the interference fringes on the platform 5 from directly above the part. When the interference fringes are evenly distributed on both sides of the V-groove, the adhesive to the part is in the middle position of the first inclined surface 25.

[0091] The first side surfaces 13 of multiple parts are sequentially and spaced apart and coated onto the baffle 8 so that the multiple parts are all located in the middle position of the first inclined surface 25.

[0092] In some embodiments, the second tooling further includes a pad 9. When the first sidewall 21 and the second sidewall 22 of the first tooling 2 are abutted in the V-groove, the pad 9 is also placed on one sidewall of the V-groove, so that the pad 9 is supported between the V-groove and the first sidewall 21 or the second sidewall 22, so as to adjust the position of the second tooling in the V-groove.

[0093] Further, the first sidewall 21 of the first tooling 2 is coated with adhesive to a coating disc, and the cylindrical angle between the first sidewall 13 and the top surface 11 is milled to form the first ridge surface 3 parallel to the first sidewall 21. The specific steps include:

[0094] Apply a smooth adhesive to the bottom surface 12 of the part on the first tooling 2. When applying the smooth adhesive to multiple blanks 1, ensure that the height is consistent at 0.01 (using the ground surface A as a reference, and using the pad 9 to control the blank 1 to be centered). Apply the adhesive and bake.

[0095] Apply adhesive to the adhesive tray to reinforce the first sidewall 21;

[0096] The cylindrical angle between the first side surface 13 and the top surface 11 is polished at low speed. The grinding size is based on the method of the upper plate and the height of the pad 9, with a reference size of (17.71+5.41)×0.707+0.15.

[0097] Grind away 0.1mm; control the disc Δt≤0.005, grind away 0.05mm (accurately record the grinding dimensions to ensure that the grinding dimensions on both sides are consistent, and the finished product's sag dimension is 5.33±0.12 (to the tip));

[0098] Low-speed polishing removes a dimension of 0.015, B = 10⁻⁵, N = 0.2, ΔN = 0.2;

[0099] Tap the lower part to clean the first tool 2.

[0100] Further, the second sidewall 22 of the first tooling 2 is coated with adhesive to a coating disc, and the cylindrical angle between the second sidewall 14 and the top surface 11 is milled to form a second ridge surface 4 parallel to the second sidewall 22. Specific steps include:

[0101] Flip the first tooling 2 over, apply the adhesive to the second sidewall 22 onto the adhesive tray, and reinforce it with adhesive;

[0102] The cylindrical angle between the second side surface 14 and the top surface 11 is polished at low speed. The grinding size is based on the method of the upper plate and the height of the pad 9, with a reference size of (17.71+5.41)×0.707+0.15.

[0103] Grind away 0.1mm; control the disc Δt≤0.005, grind away 0.05mm (accurately record the grinding dimensions to ensure that the grinding dimensions on both sides are consistent, the finished product rise dimension is 5.33±0.12 (to the tip), and the ridge chamfer width is 0.076±0.025).

[0104] Low-speed polishing removes a dimension of 0.015, B = 10⁻⁵, N = 0.2, ΔN = 0.2;

[0105] Tap the lower body.

[0106] In some implementations, the ridge edge is chamfered, and the specific steps include:

[0107] Chamfer the ridge edge by 0.1 + 0.1 × 45° to the preset width and preset angle. Here, 0.1 represents the width of the chamfer, which is 0.1 mm, and 0.1 × 45° represents the angle of the chamfer, which is 45 degrees. The length of the chamfer's hypotenuse is 0.1 mm.

[0108] Furthermore, the first ridge surface 3 and the second ridge surface 4 are finely polished, and the specific steps include:

[0109] Check the width of the ridge edge. If the width exceeds the threshold value of a, first apply a smooth adhesive to the first ridge surface 3 of the ridge edge onto the cuboid, then refine the second ridge surface 4. Next, apply a smooth adhesive to the second ridge surface 4 of the ridge edge onto the cuboid, and then refine the first ridge surface 3. The dimensions removed during the refinement of the first ridge surface 3 and the second ridge surface 4 are both a / 2.

[0110] Specifically, the following steps are included:

[0111] For the top plate glossy parts, apply glossy adhesive to a 0.5″ cuboid (material JGS2), then bake.

[0112] Upper plate: 160 / Φ300 plate, coated with adhesive;

[0113] Low-speed polishing removes a dimension of 0.01, B = 10⁻⁵, N = 0.2, ΔN = 0.1, 90° ± 1.8″;

[0114] Tap the lower part of the body to clean it;

[0115] Apply the top surface finish to the 0.5″ cuboid (material JGS2), then apply the finish and bake.

[0116] Upper plate Guangda tray: 160 pieces / Φ300 tray, coated with glue;

[0117] Low-speed polishing removes a dimension of 0.01, B = 10⁻⁵, N = 0.2, △N = 0.1, 90° ± 1.8″. The plate can only be removed from the plate after the special chamfer width passes inspection.

[0118] Tap the bottom and clean it.

[0119] Finally, quality inspection is carried out, and the quality is guaranteed (final inspection). Finished products are put into storage: the image measuring instrument is used to magnify 50 times (no more than 2 chipped edges of 0.005-0.05; chipped edges below 0.005 are ignored). The ridge corners are fully inspected and a record is provided.

[0120] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
