Description

Technical Field

[0001] This invention relates to the field of optical processing technology, and in particular to a corner adhesive tool and manufacturing method for processing high-precision right-angle roof prisms. Background Technology

[0002] Roof prisms, with their functions of reversing light paths, rotating images, directional reflection, and shortening system optical paths, are widely used in equipment observation and aiming systems. With the continuous development of optical technology, the precision of roof prisms in optical systems has been increasing in recent years. Typically, high-precision roof prisms, in addition to stringent requirements for the ridge angle accuracy, also have very strict specifications for the two transmission surfaces (isosceles) and θⅠ (the offset of the horizontal coordinates of the incident light surface image and the reflected image) and θⅡ (the offset of the vertical coordinates of the incident light surface image and the reflected image). Traditional angle-correction methods cannot simultaneously guarantee the angle between the two transmission surfaces (isosceles), as well as the θⅠ and θⅡ specifications. Due to the polyhedral nature of roof prisms, direct processing is extremely difficult and it is hard to achieve the required precision. Therefore, using corner-shaped optical adhesive tools of corresponding dimensions and combining them with the roof prism optical adhesive to create a multi-faceted optical adhesive that is easy to process and place is a common technical solution adopted in the industry.

[0003] However, similar to the difficulties in processing roof prisms, corner adhesive tools are made of the same material as roof prisms. In order to achieve the same processing precision as roof prisms, the processing of corner adhesive tools needs to achieve the same precision. The difficulty in mass production, high efficiency and high precision of corner adhesive tools has been a technical problem that has been troubling the industry. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide a corner adhesive tool and manufacturing method for processing high-precision right-angle roof prisms, in order to solve the problems of high manufacturing difficulty, poor precision, and low production efficiency of existing corner adhesive tools for processing high-precision right-angle roof prisms.

[0005] On one hand, this invention discloses a corner adhesive tool for processing high-precision right-angle roof prisms, wherein the corner adhesive tool is a decahedral optical crystal, wherein...

[0006] Surfaces 1, 2, 3, 4, and 5 are used as the working surfaces for the gloss adhesive; Surface 1 and 2, and Surface 5 and 10 respectively form two opposing right-angled ridges;

[0007] The first face and the tenth face are parallel to each other, the same size and both are isosceles hexagons. The second face and the fifth face are parallel to each other, the same size and both are isosceles trapezoids.

[0008] The base of the first isosceles hexagon shares a side with the base of the fifth isosceles trapezoid, and the base of the tenth isosceles hexagon shares a side with the base of the second isosceles trapezoid.

[0009] The third, fourth, eighth, and ninth faces are isosceles triangles of the same size and shape; the two legs of the eighth face share sides with the legs of the first and second faces on one side, respectively; the two legs of the ninth face share sides with the legs of the first and second faces on the other side, respectively; the two legs of the third face share sides with the legs of the fifth and tenth faces on one side, respectively; and the two legs of the fourth face share sides with the legs of the fifth and tenth faces on the other side, respectively.

[0010] The 8th and 9th faces are perpendicular to each other; the 3rd and 4th faces are perpendicular to each other; the 3rd and 9th faces are parallel to each other; and the 4th and 8th faces are parallel to each other.

[0011] The angle between the first and second faces and the third and fourth faces is 60°.

[0012] Faces 6 and 7 are parallelograms of the same shape and size; the four sides of face 7 share a side with the short side of face 1, the bottom side of face 4, the bottom side of face 9, and the short side of face 10; the four sides of face 6 share a side with the short side of face 1 on the other side, the bottom side of face 3, the bottom side of face 8, and the short side of face 10 on the other side.

[0013] Based on further improvements to the above tools, the length of the corner adhesive tool is the perpendicular distance between the 6th and 7th surfaces, the height is the perpendicular distance between the 2nd and 5th surfaces, and the width is the perpendicular distance between the 1st and 10th surfaces.

[0014] Based on further improvements to the above tools, the length of the corner adhesive tool is taken as the length of the ridge prism of the right-angle ridge prism to be processed plus 3 to 5 mm.

[0015] Based on further improvements to the above tools, the height calculation method for the corner adhesive tool is expressed as the formula:

[0016] In the formula,

[0017] h' represents the thickness of the right-angle roof prism to be processed.

[0018] L is the height from the prism ridge edge to the opposite bottom surface.

[0019] x represents the reserved loss, where the reserved loss is 3-5 mm.

[0020] Based on further improvements to the above tools, the width of the corner adhesive tool is not less than the sum of the vertical distance from the hexagonal edge containing the second ridge surface of the right-angle ridge prism to the parallel opposite edge and the reserved loss.

[0021] On the other hand, the present invention discloses a method for manufacturing a corner adhesive tool for processing high-precision right-angle roof prisms, the method comprising the following steps:

[0022] Determine the length, width, and height of the corner adhesive tool according to the specifications and dimensions of the right-angle roof prism;

[0023] The optical glass raw material is cut into square prisms and cubes;

[0024] The quadrangular prism cube is machined into a corner adhesive tool blank according to the length, width, and height of the corner adhesive tool;

[0025] The first surface of the corner adhesive tool is processed until the surface shape meets the preset target requirements;

[0026] The second to fifth surfaces of the corner adhesive tool are processed sequentially using the pre-processed right-angle roof prism;

[0027] Separate the tools from the adhesive pad and proceed with cleaning and inspection.

[0028] Based on a further improvement to the above method, the step of using a pre-processed right-angle roof prism to process the 2nd to 5th surfaces of the corner adhesive tool sequentially is as follows:

[0029] The first ridge surface of the processed right-angle ridge prism is bonded to the first surface of the corner adhesive tool to form an adhesive body. The second ridge surface of the right-angle ridge prism is fixed to the adhesive pad with adhesive. The second surface of the corner adhesive tool is processed. After processing, the adhesive body is separated from the adhesive pad and the second surface of the corner adhesive tool is protected with adhesive.

[0030] The first isosceles surface of the right-angle roof prism is fixed to the optical adhesive pad with optical adhesive, and the third surface of the processing tool is processed. After processing, the optical adhesive is separated from the optical adhesive pad, and adhesive is applied to protect the third surface of the corner optical adhesive tool.

[0031] The second isosceles surface of the right-angle roof prism is fixed to the optical adhesive pad with optical adhesive, and the fourth surface of the processing tool is processed. After processing, the optical adhesive is separated from the optical adhesive pad, and adhesive is applied to protect the fourth surface of the corner optical adhesive tool.

[0032] After separating the tool from the right-angle roof prism, fix the second side of the tool to the adhesive pad and then process the fifth side of the tool.

[0033] Based on a further improvement of the above method, the second, third, and fourth surfaces of the corner optical adhesive tool in the optical colloid are parallel to the second ridge surface, the first isosceles surface, and the second isosceles surface of the prism, respectively.

[0034] Based on a further improvement of the above method, the process of machining the tetrahedral cube into a corner polished adhesive tool blank includes the following steps:

[0035] The two long and wide faces and the two long and high faces of the quadrangular prism cube are fixed and polished one after another until the included angle between adjacent faces is 90°±3′. The width of the quadrangular prism cube is the sum of the length of the corner gluing tool and the reserved loss. The height of the quadrangular prism cube is the sum of the width of the corner gluing tool and the reserved loss.

[0036] The quadrangular prism cube is evenly cut into multiple smaller cubes of the same size and specifications. The length, width, and height of the smaller cubes are the sum of the length, width, and height of the corner adhesive tool and the allowable loss, respectively.

[0037] The small cubes are arranged side by side and fixed on the inclined processing plate, with the first apex of each small cube facing upwards. The first apex is then ground off to form the third surface of the corner gloss tool.

[0038] After rotating the small cube 180° up and down and fixing it, the second top corner is ground off to form the fourth surface of the corner adhesive tool;

[0039] The third face of the small cube is fixed onto the flat processing plate, and the third top corner is ground off to form the eighth face of the corner gloss tool;

[0040] The fourth face of the small cube is fixed to the flat processing plate, and the fourth top corner is ground off to form the ninth face of the corner gloss tool.

[0041] Based on a further improvement of the above method, the inclined processing tray includes a glass processing tray with multiple rows of inclined panels. Between adjacent inclined panels, there are multiple square grooves of the same shape. The shape of the square grooves is adapted to the shape of small cubes and is used to place the small cubes, with one apex of the small cubes facing upwards. Among the three planes forming the apex, the two planes forming the right-angled ridge have an angle of 60° with the bottom surface of the glass processing tray, and the third plane is parallel to the inclined panel and has an angle of 45° with the processing tray.

[0042] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0043] 1. This invention is applicable to the production of corner adhesive tools for high-precision right-angle roof prism processing, which can improve the manufacturing efficiency and tool precision of corner adhesive tools and reduce manufacturing difficulty.

[0044] 2. Based on the spatial angular relationship between the surfaces of the right-angle ridge prism and the corner gluing tool after gluing, this invention reverse-engineers the corner gluing tool using the right-angle ridge prism. This allows the precision of the part to be replicated onto the tool, greatly improving the overall pass rate of tool processing and significantly shortening the processing cycle.

[0045] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained from what is particularly pointed out in the description and drawings. Attached Figure Description

[0079] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0080] A specific embodiment of the present invention discloses a corner optical adhesive tool for processing high-precision right-angle roof prisms, wherein the corner optical adhesive tool is a decahedral optical crystal, wherein...

[0085] The 8th and 9th faces are perpendicular to each other; the 3rd and 4th faces are perpendicular to each other; the 3rd and 9th faces are parallel to each other; and the 4th and 8th faces are parallel to each other.

[0086] The angle between the first and second faces and the third and fourth faces is 60°.

[0087] Faces 6 and 7 are parallelograms of the same shape and size; the four sides of face 7 share a side with the short side of face 1, the bottom side of face 4, the bottom side of face 9, and the short side of face 10; the four sides of face 6 share a side with the short side of face 1 on the other side, the bottom side of face 3, the bottom side of face 8, and the short side of face 10 on the other side.

[0088] Specifically, such as Figure 1 As shown, the corner adhesive tool disclosed in this embodiment is a decahedral structure, wherein the first face 1 and the second face 2, and the fifth face 5 and the tenth face 10 respectively form two opposing right-angled ridges;

[0089] Face 1 and face 10 are parallel to each other, the same size and both are isosceles hexagons. Face 2 and face 5 are parallel to each other, the same size and both are isosceles trapezoids.

[0090] The base of the first isosceles hexagon (face 1) shares a side with the base of the fifth isosceles trapezoid (face 5), and the base of the tenth isosceles hexagon (face 10) shares a side with the base of the second isosceles trapezoid (face 2).

[0091] The third face 3, the fourth face 4, the eighth face 8, and the ninth face 9 are isosceles triangles of the same size and shape; the two legs of the eighth face 8 share sides with the legs of the first face 1 and the second face 2 on one side, respectively; the two legs of the ninth face 9 share sides with the legs of the first face 1 and the second face 2 on the other side, respectively; the two legs of the third face 3 share sides with the legs of the fifth face 5 and the tenth face 10 on one side, respectively; the two legs of the fourth face 4 share sides with the legs of the fifth face 5 and the tenth face 10 on the other side, respectively.

[0092] The 8th face and the 9th face are perpendicular to each other; the 3rd face and the 4th face are perpendicular to each other; the 3rd face and the 9th face are parallel to each other; the 4th face and the 8th face are parallel to each other.

[0093] The angle between face 1, face 2 and face 3, face 4 is 60°;

[0094] Face 6 and face 7 are parallelograms of the same shape and size; the four sides of face 7 share the same side with the short side of face 1 on one side, the bottom side of face 4, the bottom side of face 9, and the short side of face 10 on one side; the four sides of face 6 share the same side with the short side of face 1 on the other side, the bottom side of face 3, the bottom side of face 8, and the short side of face 10 on the other side.

[0095] Furthermore, the length of the corner adhesive tool is the perpendicular distance between the 6th and 7th surfaces, the height is the perpendicular distance between the 2nd and 5th surfaces, and the width is the perpendicular distance between the 1st and 10th surfaces.

[0096] Specifically, in this embodiment, the height of the corner adhesive tool is the vertical distance between the 6th face 6 and the 7th face 7, the height is the vertical distance between the 2nd face 2 and the 5th face 5, and the width is the vertical distance between the 1st face 1 and the 10th face 10.

[0097] Furthermore, the length of the corner adhesive tool is taken as the length of the ridge prism of the right-angle ridge prism to be processed plus 3 to 5 mm.

[0098] Specifically, the corner adhesive tool in this embodiment must correspond to the size and specifications of the right-angle roof prism to be processed. Generally, right-angle roof prisms have a 9-sided structure, such as... Figure 2 As shown, the first ridge surface a and the second ridge surface b are perpendicularly symmetrical along the ridge edge h, and both have the same shape, being hexagonal; e consists of two triangular non-working surfaces, c is the first isosceles surface, and d is the second isosceles surface, with c and d perpendicular to each other; f consists of two isosceles trapezoidal non-working surfaces; g is a rectangular non-working surface. The angle between ridge surfaces a and b and isosceles surfaces c and d is 60°, and the distance between the two perpendicular lines sharing the same side of triangular non-working surface e and isosceles surfaces c and d is the chord length i of the prism. In this embodiment, the length of the corner adhesive tool is the right-angle ridge prism edge length h plus 3-5 mm.

[0099] Furthermore, the method for calculating the height of the corner adhesive tool is expressed as a formula:

[0100] In the formula,

[0101] h' represents the thickness of the right-angle roof prism to be processed.

[0102] L is the height from the prism ridge edge to the opposite bottom surface.

[0103] x represents the reserved loss, where the reserved loss is 3-5 mm.

[0104] Furthermore, the width of the corner adhesive tool is not less than the sum of the vertical distance from the hexagonal edge containing the second ridge surface of the prism to the parallel opposite edge and the reserved loss.

[0105] In this embodiment, as Figure 3 As shown, the prism ridge edge length is 40mm and the chord length is 54.25mm. The width of the second ridge surface, i.e., the perpendicular distance from the edge of the hexagon containing the second ridge surface to the parallel opposite edge, is 20mm. The corner adhesive tool is designed according to the following principles: the tool length is the prism ridge edge length plus the allowance for processing loss, and the height is... Figure 3 The height dimension is calculated based on the dimensions shown. =29.12mm) Considering processing loss, the height loss per processing is 0.05-0.07mm, and the tool life is 40-60 times. Based on this, a certain height is increased. The width dimension is the width of the second ridge surface of the prism, that is, the vertical distance from the edge to the parallel opposite edge plus the reserved processing loss. Then the length × width × height of the corner adhesive tool in this embodiment is: 41mm × 22.1mm × 32.1mm.

[0106] Another embodiment of the present invention discloses a method for manufacturing a corner adhesive tool for processing a high-precision right-angle roof prism, the method comprising the following steps:

[0107] Determine the length, width, and height of the corner adhesive tool according to the specifications and dimensions of the right-angle roof prism;

[0108] The optical glass raw material is cut into square prisms and cubes;

[0109] The quadrangular prism cube is machined into a corner adhesive tool blank according to the length, width, and height of the corner adhesive tool;

[0110] The first surface of the corner adhesive tool is processed until the surface shape meets the preset target requirements;

[0111] The second to fifth surfaces of the corner adhesive tool are processed sequentially using the pre-processed right-angle roof prism;

[0112] Separate the tools from the adhesive pad and proceed with cleaning and inspection.

[0113] Specifically, such as Figure 5 As shown, the specific processing steps of the corner adhesive tool in this embodiment are as follows:

[0114] Step S1: Determine the length, width, and height of the corner adhesive tool according to the specifications and dimensions of the right-angle roof prism.

[0115] Specifically, the detailed process of this step has been described in the previous embodiment and will not be repeated here. It should be noted that, in order to better illustrate the specific implementation of the invention, this embodiment adopts the specifications and dimensions of the corner adhesive tool in the previous embodiment.

[0116] Step S2: Cut the optical glass raw material into a quadrangular prism cube.

[0117] Specifically, in the previous embodiment, the length, height, and width of the corner adhesive tool are 41mm, 32.1mm, and 22.1mm, respectively. To facilitate subsequent processing, the optical glass raw material is cut into a quadrangular prism cube using a blanking machine (preferred model: Q8040). The length of the quadrangular prism is an integer multiple of the height of the corner adhesive tool plus a certain allowance for loss, the width is the length of the corner adhesive tool plus the allowance for loss, and the height is the width of the corner adhesive tool plus the allowance for loss. Therefore, the preferred dimensions of the quadrangular prism cube are 116mm, 44mm, and 35mm.

[0118] Step S3: The quadrangular prism cube is machined into a corner gloss tool blank according to the length, width, and height of the corner gloss tool.

[0119] Furthermore, the process of machining the tetrahedral cube into a corner polished adhesive tool blank includes the following steps:

[0120] The two long and wide faces and the two long and high faces of the quadrangular prism cube are fixed and polished one after another until the included angle between adjacent faces is 90°±3′. The width of the quadrangular prism cube is the sum of the length of the corner gluing tool and the reserved loss. The height of the quadrangular prism cube is the sum of the width of the corner gluing tool and the reserved loss.

[0121] The quadrangular prism cube is evenly divided into multiple smaller cubes of the same size and specifications along its length. The length, width, and height of the smaller cubes are the sum of the length, width, and height of the corner adhesive tool and the allowable loss, respectively.

[0122] The small cubes are arranged side by side and fixed on the inclined processing plate, with the first apex of each small cube facing upwards. The first apex is then ground off to form the third surface of the corner gloss tool.

[0123] After rotating the small cube 180° up and down and fixing it, the second top corner is ground off to form the fourth surface of the corner adhesive tool;

[0124] The third face of the small cube is fixed onto the flat processing plate, and the third top corner is ground off to form the eighth face of the corner gloss tool;

[0125] The fourth face of the small cube is fixed to the flat processing plate, and the fourth top corner is ground off to form the ninth face of the corner gloss tool.

[0126] Specifically, in this embodiment, the process of shaping a square prism cube into a corner adhesive tool is as follows: Figure 6 As shown, it includes the following steps:

[0127] Step S31: Fix and grind the two long and wide faces and the two long and high faces of the quadrangular prism cube one after another until the included angle between adjacent faces is 90°±3′.

[0128] Specifically:

[0129] First, two faces of the 44mm×116mm quadrangular prism cube and two faces of the 35mm×116mm quadrangular prism cube are successively ground on a single-axis machine (preferred model CM300) with diamond abrasive as auxiliary material, so that the included angle between the ground surfaces is controlled at 90°±3′.

[0130] Then, the two 44mm×116mm faces of the quadrangular prism cube are fixed to the glass processing plate using industrial paraffin wax processed by an electric heating plate, and then milled by a milling machine (preferably model XM260) to mill the height of the quadrangular prism cube to not less than 32.3mm.

[0131] Next, the two 44mm×116mm faces of the quadrangular prism cube are hand-ground to 32.1mm using a single-axis machine (preferably model CM300) with diamond abrasive as an auxiliary material, and the parallelism of the entire disc is 0.02.

[0132] Then, the two faces of the 32.1mm×116mm are fixed to the glass processing plate with industrial paraffin using an electric heating plate, and milled on a milling machine (preferably model XM260) until the width of the quadrangular prism cube is not less than 41.2mm.

[0133] Next, the two 32.1mm×116mm faces of the quadrangular prism cube are hand-ground to 41mm using a single-axis machine (preferably model CM300) with diamond abrasive as an auxiliary material, and the parallelism of the entire plate is controlled to 0.02.

[0134] Step S32: Divide the quadrangular prism cube into multiple smaller cubes of the same size and specifications along its length. The length, width, and height of the smaller cubes are the sum of the length, width, and height of the corner adhesive tool and the allowable loss, respectively.

[0135] After the two 32.1mm×116mm faces and the two 41mm×116mm faces are ground, a glass auxiliary strip is used on the square prism cube, and industrial paraffin is heated using an electric heating plate to fix the square prism cube on a fully automatic inner circle slicer (preferably model JB0100). Cutting is performed every 22.1mm from the 116mm edge, dividing the square prism cube into five smaller cubes of 41mm×32.1mm×22.1mm.

[0136] Step S33: Arrange the small cubes side by side on the inclined processing plate, keeping the first apex of each small cube facing upwards, and grind off the first apex to form the third surface of the corner gloss tool.

[0137] Furthermore, such as Figure 7 As shown, the inclined processing tray includes a glass processing tray with multiple rows of inclined panels. Between adjacent inclined panels, there are multiple square grooves of the same shape. The shape of the square grooves is adapted to the shape of small cubes and is used to place the small cubes, with one apex of the small cubes facing upwards. Among the three planes forming the apex, two planes forming the right-angled ridge have an angle of 60° with the bottom surface of the glass processing tray, and the third plane is parallel to the inclined panel and has an angle of 45° with the processing tray.

[0138] Preferred, such as Figure 8 As shown, small cubes are placed side by side on an inclined processing plate. Industrial paraffin wax is processed using a hot plate to fix all the small cubes on the processing plate. The first apex corner is ground off on a milling machine of preferred model XM260 to form the third surface of the corner polishing tool.

[0139] Step S34: After rotating the small cube 180° up and down and fixing it, grind off the second top corner to form the fourth surface of the corner adhesive tool;

[0140] Specifically, such as Figure 9 As shown, rotate the small cubes 180° up and down, and use an electric heating plate to process industrial paraffin wax to fix all the small cubes on the processing plate. With the second apex facing up, grind off the second apex with an upper milling machine to form the fourth surface of the corner polishing tool.

[0141] Step S35: Fix the third face of the small cube onto the flat processing plate, grind off the third top corner to form the eighth face of the corner gloss tool.

[0142] Specifically, such as Figure 10As shown, the third face of the small cube is processed with industrial paraffin wax using a hot plate to fix all the small cubes onto the processing plate. With the third apex facing upwards, the third apex is ground off using a milling machine to form the ninth face of the corner polishing tool. The reason for not continuing to use the inclined processing plate in this step is that the third and fourth faces of the small cubes, i.e., the corner polishing tool being processed, have already been milled, and the fixing effect on the inclined processing plate is reduced. The preferred method is to fix the processed third face onto a flat processing plate, and take advantage of the parallel relationship between the third and ninth faces to grind off the third apex with a milling machine to obtain the ninth face of the corner polishing tool.

[0143] Step S36: Fix the fourth face of the small cube onto the flat processing plate, grind off the fourth top corner to form the ninth face of the corner gloss tool.

[0144] Specifically, this step is similar to the previous step, such as... Figure 11 As shown, the processed fourth surface is fixed on a flat processing plate. Taking advantage of the parallel relationship between the fourth and eighth surfaces, the fourth apex corner is ground off with a milling machine to obtain the eighth surface of the corner polishing tool.

[0145] After completing the above steps, you will obtain a finished corner glossy tool.

[0146] Step S4: Process the first surface of the corner adhesive tool until the surface shape meets the preset target requirements.

[0147] Specifically, such as Figure 12 As shown, the first step of polishing the corner polishing tool starts with polishing the first surface. Industrial paraffin wax is heated to fix the tenth surface of the corner polishing tool on the processing mirror plate. The first surface is fixed facing the ring polishing die. After fine grinding and polishing by the ring polishing machine, the surface shape of the processed surface is measured with a plane interferometer. The preset index requirement is that the aperture ≤ 0.5 and the local aperture ≤ 0.2. If the surface shape meets the above preset index requirements, the processing of the first surface is completed.

[0148] Step S5: Use the processed right-angle ridge prism to process the 2nd to 5th surfaces of the corner adhesive tool in sequence.

[0149] Furthermore, the detailed sub-procedures of this step include:

[0150] Step S51: The first ridge surface of the processed right-angle ridge prism is bonded to the first surface of the corner adhesive tool to form an adhesive body. The second ridge surface of the right-angle ridge prism is fixed to the adhesive pad with adhesive. The second surface of the corner adhesive tool is processed. After processing, the adhesive body is separated from the adhesive pad, and adhesive is applied to protect the second surface of the corner adhesive tool.

[0151] Step S52: Fix the first isosceles surface of the prism to the optical adhesive pad with optical adhesive, process the third surface of the tool, and after processing, separate the optical adhesive from the optical adhesive pad and apply adhesive to protect the third surface of the corner optical adhesive tool.

[0152] Step S53: Fix the second isosceles surface of the prism to the optical adhesive pad with optical adhesive, process the fourth surface of the tool, and after processing, separate the optical adhesive from the optical adhesive pad and apply adhesive to protect the fourth surface of the corner optical adhesive tool.

[0153] Specifically, such as Figure 4 As shown, the optical adhesive body is composed of the first surface 1 of the corner optical adhesive tool on the left and the first ridge surface a of the right-angled roof prism on the right, bonded together with optical adhesive. The second surface 2, the third surface 3, and the fourth surface 4 of the corner optical adhesive tool on the left are parallel to the second ridge surface b, the first isosceles surface c, and the second isosceles surface d of the right-angled roof prism, respectively. During the manufacturing process, the second ridge surface b of the roof prism is applied as a disc on an optical adhesive pad, and the second surface 2 of the corner optical adhesive tool is finely ground and polished. The first isosceles surface c of the right-angled roof prism is applied as a disc on an optical adhesive pad, and the third surface 3 of the corner optical adhesive tool is finely ground and polished. The second isosceles surface d of the right-angled roof prism is applied as a disc on an optical adhesive pad, and the fourth surface 4 of the corner optical adhesive tool is finely ground and polished.

[0154] To mass-produce corner adhesive tools, multiple right-angle roof prisms and multiple corner adhesive tools can be used to simultaneously adhesive the adhesive onto an adhesive pad to form a mirror plate for mass production.

[0155] Specifically, multiple photopolymers of the same specification are simultaneously photopolymerized onto a photopolymer pad to form a mirror disk to be processed. The same type of plane of each corner photopolymer tool is processed simultaneously. After processing, if the parallel height difference between the processed surface of each photopolymer and the photopolymer pad is ≤0.002mm, the processing meets the standard.

[0156] The right-angle roof prism is coated with optical adhesive onto a circular fixture, specifically a corner optical adhesive tooling surface processed on an optical adhesive pad. The surrounding triangular prisms are fitted with glass trays, and the center contains the optical adhesive. Preferably, in this embodiment, an optical adhesive pad with a diameter of φ220~φ300 is used. Using a plane interferometer, its surface shape is measured to ensure that the aperture is ≤0.5 and the local aperture is ≤0.2, thus meeting the requirements.

[0157] Step S54: After separating the tool from the prism, fix the second side of the tool to the adhesive pad with adhesive, and process the fifth side of the tool.

[0158] Specifically, since the corner gluing tool has already completed the polishing of the second side, and the second side is parallel to the fifth side, this step does not require the use of a right-angle roof prism. The second side of the corner gluing tool can be directly glued onto the gluing pad, and the fifth side can be polished directly using a ring polisher.

[0159] Step S6: Separate the tool from the adhesive pad and perform cleaning and inspection procedures.

[0160] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
