Description

Technical Field

[0001] The present invention relates to the technical field of optical prisms, and in particular to an optical prism with good light refraction effect and its processing method. Background Art

[0002] An optical prism is a transparent object surrounded by planes that intersect pairwise but are not parallel to each other, used for splitting light or dispersing light beams. A prism is a polyhedron made of a transparent material. Prisms can be classified into several types according to their properties and uses. From a physics perspective, a prism has the function of refracting light rays, but does not have the function of focusing. Therefore, it can only change the direction of refracted light rays but cannot change the divergence or convergence of refracted light rays. The light rays passing through a triangular prism will no longer extend in the original direction after being refracted, and will deviate in another direction, which is what we commonly call the deviation effect of the prism. In addition, a prism can form an image. However, the image formed by the prism is a virtual image, and the image observed by the naked eye through the prism is closer to the top of the prism than the actual object.

[0003] Chinese Patent Publication No. is CN108693577A, and the authorization announcement date is October 23, 2018. An optical prism module includes a first reflection covering film, prism a surface, a first included angle, a second reflection covering film, prism b surface, a second included angle, prism c surface, an imaging device, an imaging device screen, a third included angle, prism d surface, a third reflection covering film, a fourth included angle, prism e surface, a first refracted ray, and a second refracted ray. The beneficial effects achieved by the present invention are: directly facing the prism c surface of the optical prism module with the imaging device screen, the light of the imaging device screen enters the interior of the optical prism module from the incident ray direction, reaches the prism d surface, is reflected by the third reflection covering film to the prism b surface, and then is reflected by the second reflection covering film to the prism e surface to project the image. The imaging device screen and the optical prism module are directly projected, avoiding the dispersion of the projection light source and having higher projection clarity; the image formed by this optical prism has no specular reflection, with better imaging effect and higher imaging integrity rate.

[0004] In the above prior art solution, the optical prism can improve the imaging effect and make the imaging integrity rate higher. However, when performing light refraction, since the optical prism itself is made of transparent materials such as glass or crystal, during refraction, some light rays will directly shoot out, resulting in difficulty in increasing the refractive index of the refracted light rays of the optical prism. Therefore, we propose an optical prism with good light refraction effect and its processing method to solve the problems raised above. Summary of the Invention

[0016] Step 2: Cut the prism material into strips larger than the design size by 2 to 3 mm.

[0017] Step 3: Grind and polish the cut strips, grind the corresponding angles of the strips according to the design size, with an angle error of 2 to 4 degrees, to obtain the first rough material.

[0018] Step 4: Detect the first rough material, and detect the appearance and image refraction effect of the first rough material through a grid plate under light.

[0019] Step 5: Cut the first rough material again according to the detection result, into the second rough material with a length greater than the design size by 0.5 to 1 mm and a width greater than the design size by 2 to 3 mm.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. In the present invention, a reflective cloth is provided to reflect light. The drive motor is used to control the rotation of the reflective cloth reel and the bead chain gear. Driven by the bead chain outside the bead chain gear, the reflective cloth slowly moves downward until the reflective cloth moves to one side of the bead chain limit ring. At the same time, the taut bead chain can strongly flatten the reflective cloth, so that the reflective cloth can fully refract the light received by the internal prism, solving the problem that since the optical prism itself is made of transparent materials such as glass or crystal, during refraction, some light will directly shoot out, resulting in difficulty in increasing the refractive index of the refracted light of the optical prism.

[0026] 2. The atomizing glass provided in the present invention is an optoelectronic glass with a sandwich structure formed by laminating a liquid crystal film between two layers of glass and integrally molding through high-temperature and high-pressure gluing. The user controls the transparent and opaque states of the atomizing glass by controlling the on-off of the current. When the atomizing glass is powered off, the liquid crystal molecules inside the electro-controlled atomizing glass will present an irregular dispersion state, and at this time, the atomizing glass presents an opaque appearance state and will undergo diffuse reflection, so that the light to be refracted can be disrupted and scattered, making the refracted light become an irregular light beam, meeting different photography and experimental requirements; when the atomizing glass is powered on, the liquid crystal molecules inside are arranged neatly and the light can penetrate freely, and at this time, the atomizing glass instantly presents a transparent state.

[0042] A processing method of an optical prism with good light refraction effect includes the following steps:

[0049] Step Seven: Chamfer the first fine material, clean and dry it to obtain the inner prism 20;

[0050] Step Eight: Adhere the fixing blocks 19 at five corners of the inner prism 20, seal and arrange the inner glass 13 between adjacent fixing blocks 19, inject glue into the internal sealant groove 16, discharge the air bubbles in the sealant through vibration and wait for it to solidify;

[0051] Step Nine: Install the drive motor 21 and the reflective cloth reel 9, wind the lower end of the bead chain 11 into the internal bead chain limit ring 17, externally and fixedly seal and install the atomized glass 18 on the fixing block 19, and adhesively connect the upper end and the lower end of the prism area 2 with the battery base 1 and the reflective cloth base 3 respectively.

[0052] Working Principle: When in use, first select a surface of the prism area 2 to contact the light, adjust the position and angle of the optical prism according to the refraction requirements. When light refraction operation is needed, lower the reflective cloth 7 on the refraction surface where the light contacts. By pressing the button module 5 on the refraction surface, the button module 5 connects the drive motor 21 and the battery 14 electrically, and the drive motor 21 can be started, thereby rotating the reflective cloth reel 9 and the bead chain gear 10. The bead chain gear 10 drives the bead chain 11 to roll through meshing connection. When the bead chains 11 on both sides roll, they drive the reflective cloth stretching rod 8 at the lower end of the reflective cloth 7. With the rotation of the reflective cloth reel 9 and the pulling of the bead chain 11, the reflective cloth 7 unfolds smoothly downward until the lower end of the reflective cloth 7 moves to one side of the bead chain limit ring 17. At this time, the reflective cloth 7 can effectively reflect the light passing through the inner prism 20, reducing the waste of light quantity, thereby improving the refraction effect. After use, press the button module 5, and drive the reflective cloth 7 to retract upward with the reflective cloth reel 9 and the bead chain 11 through the reverse rotation of the drive motor 21, hiding it inside the reflective cloth groove 6. When light diffuse reflection is needed, select a surface of the prism area 2 to contact the light, adjust the position and angle of the optical prism according to the refraction requirements, and control the power supply of the atomized glass 18 on this surface to be turned off by pressing the button module 5 on the refraction surface. At this time, the atomized glass 18 presents an opaque appearance state, and diffuse reflection occurs, thereby scattering the light that needs to be refracted and making the refracted light become irregular light beams to meet different photography and experimental requirements.
