Description

Technical Field

[0001] The present application relates to the technical field of optical part processing, and more specifically, to a gluing and positioning tooling for a right-angle prism group. Background Art

[0002] A right-angle prism is an optical element with a right-angle shape, which is composed of five planes, two mutually perpendicular right-angle faces, two mutually parallel side faces, and an inclined face, and is mainly used to change the optical path direction. Multiple right-angle prisms are glued and assembled together to form a right-angle prism group.

[0003] In the current right-angle prism group, a three-glued right-angle prism group is required. This right-angle prism group includes two small prisms and a large right-angle prism, and the two small prisms are glued to the inclined face of the large right-angle prism.

[0004] During processing, the conventional operation is to manually glue on the operating table, usually using the method of gluing and detecting and measuring at the same time. However, during the process of manual gluing, both the gluing position and the gluing distance are ensured by the operator measuring and gluing simultaneously during the gluing process. The problem with this is that the gluing position and the gluing distance move during manual gluing and positioning, resulting in low gluing accuracy. If the processing accuracy cannot be guaranteed, it needs to be disassembled for repair, causing damage to the parts and reducing the product yield.

[0005] Therefore, the existing technology still needs to be improved and developed. Summary of the Utility Model

[0016] In some embodiments, support bodies are provided on both the first abutting body and the second abutting body.

[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application clearer and more understandable, the following further details this application in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0035] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it can be directly or indirectly located on that other component. When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to that other component. The orientations or positions indicated by the terms "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientations or positions shown in the accompanying drawings, and are only for the convenience of description and cannot be construed as a limitation on the technical solution of the present application. The terms "first" and "second" are only used for the purpose of convenient description and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of technical features. The meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0036] The right-angle prism group is formed by gluing a plurality of right-angle prisms to form a combined structure. The right-angle prism group generally refers to combining two or more right-angle prisms together in a specific manner to achieve a more complex optical path control purpose.

[0037] When using right-angle prisms in combination, it is necessary to carefully consider the incident angle, reflection angle of each prism and their relative positions to ensure the correct guiding of the optical path and the required optical effects, which are also the key factors determining the performance of the final right-angle prism group.

[0038] It can be seen from this that the design and gluing of the right-angle prism group is a highly precise process aimed at achieving precise guiding of the optical path. Therefore, the gluing between each prism needs to be completed through precise alignment and firm gluing processes to ensure the accuracy of the optical path and long-term stability.

[0039] However, the existing gluing method relies on manual operation to tightly press each right-angle prism. The one-time qualification rate of this method is relatively low. When the accuracy does not meet the requirements, it needs to be repaired, disassembled, and reglued, resulting in low gluing accuracy.

[0040] The following describes the gluing positioning tooling for the right-angle prism group in the embodiments of the present application in conjunction with the accompanying drawings.

[0041] Please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 which show the structural schematic diagram of the gluing positioning tooling for the right-angle prism group of the present application. Among them, the right-angle prism group includes multiple right-angle prisms 4, and the gluing positioning tooling includes a first abutting body 1 and a second abutting body 2. The right-angle prisms are glued in sequence through the first abutting body 1 and the second abutting body 2.

[0042] Specifically, referring to Figure 1 , the first abutting body 1 is provided with a first supporting plane 11. The first supporting plane is provided with a first positioning protrusion 12 and a second positioning protrusion 13. At least two first positioning protrusions 12 are provided and are used to support the right-angle surface 41 of the right-angle prism. The second positioning protrusion 13 is used to abut against the side surface 42 of the right-angle prism.

[0043] Referring to Figure 2 , the second abutting body 2 is provided with a second supporting plane 21. The second supporting plane is provided with a third positioning protrusion 22 and a fourth positioning protrusion 23. At least two third positioning protrusions 22 are provided and are used to support the right-angle surface 41 of the right-angle prism. The fourth positioning protrusion 23 is used to abut against the edge 44 of the right-angle prism.

[0044] It can be understood that, referring to Figure 1 - Figure 3 , the right-angle prism 4 includes two right-angle surfaces 41, two side surfaces 42, an inclined surface 43, and multiple edges 44. The first to fourth positioning protrusions 23 are all in the form of bump structures. The first positioning protrusion 12 is used to support the right-angle surface 41 of the right-angle prism. Here, the support means that the right-angle surface 41 of the right-angle prism abuts against the first positioning protrusion 12, and the right-angle prism can be stably placed without external support. At this time, the inclined surface 43 of the right-angle prism is exposed, facilitating gluing. Similarly, the second positioning protrusion 13 is arranged and functions in the same way as the first positioning protrusion 12, and will not be elaborated here.

[0045] Of course, multiple first positioning protrusions 12 and third positioning protrusions 22 are provided to form a support structure capable of supporting the right-angle prism.

[0046] Regarding the second positioning protrusion 13, after the first positioning protrusion 12 supports a right-angle prism, it is equivalent to positioning the right-angle prism. When gluing other right-angle prisms to the inclined surface 43 of this right-angle prism, it is also necessary to position the other prisms. The second positioning protrusion 13 is used to abut and limit the side surface 42 of the other prisms, so as to ensure that the right-angle surface 41 of the other prisms is glued to the right-angle prism within the specified dimensional range.

[0047] Similarly, after the third positioning protrusion 22 supports a right-angle prism, it is equivalent to positioning the right-angle prism. When gluing other right-angle prisms to the inclined surface 43 of this right-angle prism, it is also necessary to position the other prisms. The fourth positioning protrusion 23 is used to abut and limit the edge 44 of the other prisms, so as to ensure that the right-angle surface 41 or other surfaces of the other prisms can be glued to the right-angle prism within the specified dimensional range.

[0048] In summary, through the gluing and positioning tooling of this embodiment, a right-angle prism in the right-angle prism group can be supported and positioned, and the non-gluing surfaces of other right-angle prisms can be abutted and limited, so that each right-angle prism in the right-angle prism group can be dimensionally positioned, and then two or more right-angle prisms can be accurately glued together in a specific manner, improving the gluing accuracy and greatly increasing the one-time qualification rate of gluing.

[0049] In some embodiments, referring to Figure 4 - Figure 6 , the right-angle prism group includes a main prism 45, a first prism 46, and a second prism 47. The right-angle surfaces 41 of the first prism 46 and the second prism 47 are connected to the inclined surface 43 of the main prism 45. Among them, the main prism 45 is a right-angle prism with a larger volume, and the first prism 46 and the second prism 47 are right-angle prisms with a smaller volume. This right-angle prism group is to glue and fix two small right-angle prisms to the inclined surface 43 of the large right-angle prism.

[0050] Both the first positioning protrusion 12 and the third positioning protrusion 22 are used to support the right-angle surface 41 of the main prism 45. The second positioning protrusion 13 is used to abut the side surface 42 of the first prism 46, and the fourth positioning protrusion 23 is used to abut the edge 44 of the second prism 47.

[0051] When gluing the right-angle prism group, first use the first abutting body 1 to glue the main prism 45 and the first prism 46. According to the size of the main prism 45, the first positioning protrusion 12 and the second positioning protrusion 13 are distributed and arranged on the first supporting plane 11. Place the first abutting body 1 stably so that the first supporting plane 11 is at an angle convenient for gluing. Exemplarily, the first supporting plane 11 is perpendicular to the ground, and the first positioning protrusions 12 are spaced apart on the first supporting plane 11.

[0052] Then, the two right-angle faces 41 of the main prism 45 are respectively abutted against at least one first positioning protrusion 12, ensuring that each right-angle face 41 of the main prism 45 is abutted against at least one first positioning protrusion 12. At this time, one side face 42 of the main prism 45 is abutted against the first supporting plane 11, and the other side face 42 is exposed. Moreover, the inclined face 43 of the main prism 45 is exposed. In this way, the main prism 45 can be supported on the first supporting plane 11 by the first positioning protrusion 12.

[0053] Then, apply the curing glue to the right-angle face 41 of the first prism 46 to be glued, and attach the right-angle face 41 coated with the curing glue to the inclined face 43 of the main prism 45. Adjust the position of the first prism 46 so that the side face 42 of the first prism 46 abuts against the second positioning protrusion 13. At this time, the relative position of the first prism 46 on the main prism 45 can be positioned. After the curing glue cures, the first prism 46 can be positioned and glued to the main prism 45.

[0054] After the first prism 46 is glued, use the second abutting body 2 to glue the second prism 47 to the main prism 45. The third positioning protrusion 22 on the second abutting body 2 is arranged in the same way as the first positioning protrusion 12 on the first abutting body 1. Then, the two right-angle faces 41 of the main prism 45 are respectively abutted against the third positioning protrusion 22, and the third positioning protrusion 22 supports the main prism 45 glued with the first prism 46 on the second supporting plane 21.

[0055] Among them, since the fourth positioning protrusion 23 is used to abut against the second prism 47, different from the first abutting body 1, the setting position of the fourth positioning protrusion 23 on the second abutting body 2 is different from that of the second positioning protrusion 13. Relative to the position of the second positioning protrusion 13 on the first supporting plane 11, the fourth positioning protrusion 23 is arranged on the other side of the second supporting plane 21. For example, if the second positioning protrusion 13 is arranged on the left side of the first supporting plane 11, then the fourth positioning protrusion 23 is arranged on the right side of the second supporting plane 21.

[0056] After the main prism 45 is fixed to the second supporting plane 21, apply the curing glue to the right-angle face 41 of the second prism 47 to be glued, and attach the right-angle face 41 coated with the curing glue to the inclined face 43 of the main prism 45. Then, adjust the position of the second prism 47, and abut against the edge 44 of the second prism 47 through the third positioning protrusion 22 to limit the position of the second prism 47 relative to the main prism 45, and the positioning of the second prism 47 on the main prism 45 can be achieved. After the curing glue cures, the second prism 47 can be positioned and glued to the main prism 45.

[0057] At this time, the positioning and gluing of the first prism 46 and the second prism 47 on the main prism 45 are completed. The main prism 45 is positioned by the first positioning protrusion 12 and the third positioning protrusion 22. The first prism 46 realizes the position positioning with the main prism 45 through the second positioning protrusion 13, and the second prism 47 realizes the position positioning with the main prism 45 through the fourth positioning protrusion 23. The operation is convenient and the positioning is accurate.

[0058] Furthermore, the first positioning protrusion 12, the second positioning protrusion 13, and the third positioning protrusion 22 include spherical protrusions, and the fourth positioning protrusion 23 includes a cylindrical protrusion. Among them, since the first positioning protrusion 12, the second positioning protrusion 13, and the third positioning protrusion 22 are used to abut and support the surface of the right-angle prism, they can be set as spherical because the spherical positioning protrusions can provide good support for the plane, and the spherical surfaces thereof can be applicable to right-angle prisms in more size ranges. The fourth positioning protrusion 23 is used to abut the edge 44 of the right-angle prism, and the spherical structure is not suitable for abutting the edge 44, and it is easy to have an unstable abutting situation. Therefore, the fourth positioning protrusion 23 is set as a cylindrical structure, and the top surface or the bottom surface of the cylindrical structure is used to abut the edge 44, and the abutting effect is more stable.

[0059] Of course, the fourth positioning protrusion 23 can also be set as a prismatic protrusion. Similarly, the first positioning protrusion 12, the second positioning protrusion 13, and the third positioning protrusion 22 can also be set as cylindrical protrusions or prismatic protrusions.

[0060] In some embodiments, to meet more specific gluing methods, refer to Figure 2 and Figure 6 , a third abutting body 3 is provided on the second supporting plane 21. The third abutting body 3 is provided with a third supporting plane 31 parallel to the second supporting plane 21. The third positioning protrusion 22 is provided on the third supporting plane 31, and the fourth positioning protrusion 23 is provided on the second supporting plane 21 and protrudes towards the third supporting plane 31.

[0061] Refer to Figure 6 , when the first prism 46 is glued to the main prism 45, a part of the first prism 46 protrudes from the main prism 45. At this time, when the main prism 45 and the first prism 46 are supported on the second abutting body 2, the protruding part of the first prism 46 will hinder the fitting distance between the main prism 45 and the second supporting plane 21. For this reason, the third abutting body 3 is provided on the second abutting body 2. After the third abutting body 3 is provided, the main prism 45 is supported on the third abutting body 3, and there will be a certain interval between the main prism 45 and the second supporting plane 21. The protruding part of the first prism 46 can be accommodated in this part of the interval, and the main prism 45 can be smoothly attached to the third supporting plane 31.

[0062] In some embodiments, refer to Figure 1 andFigure 2 On the first support plane 11, three first positioning protrusions 12 are provided. Two of the three first positioning protrusions 12 are used to support one right-angle face 41 of the right-angle prism, and the other first positioning protrusion 12 is used to support the other right-angle face 41 of the right-angle prism. On the third support plane 31, three third positioning protrusions 22 are provided, and the arrangement orientation of the third positioning protrusions 22 is the same as that of the first positioning protrusions 12.

[0063] Understandably, if you want to support the right-angle prism, at least two first positioning protrusions 12 are required. When the right-angle prism is supported by two first positioning protrusions 12, each first positioning protrusion 12 abuts against one right-angle face 41 respectively, which is equivalent to each right-angle face 41 having a support point. When only one support point supports the right-angle face 41, the right-angle face 41 is likely to shake relative to the support point, resulting in unstable support.

[0064] For this reason, three first positioning protrusions 12 are provided on the first support plane 11. Two of the first positioning protrusions 12 abut against one right-angle face 41, and the other first positioning protrusion 12 abuts against the other right-angle face 41. In this way, one right-angle face 41 has two support points, and the right-angle face 41 will not shake relative to these two support points, which will greatly improve the stability of the support. And for the other right-angle face 41, only one first positioning protrusion 12 needs to be provided to stably support the right-angle prism.

[0065] Of course, the number of the first positioning protrusions 12 is not limited to three. More first positioning protrusions 12 can also be provided on the first support plane 11. Exemplarily, four, five, or six first positioning protrusions 12 are provided. Similarly, more third positioning protrusions 22 can also be provided on the third support plane 31.

[0066] In some embodiments, refer to Figure 1 、 Figure 2 、 Figure 4 - Figure 6 , a concave first diversion groove 14 is provided on the first support plane 11, and the first diversion groove 14 is arranged between the first positioning protrusion 12 and the second positioning protrusion 13; a concave second diversion groove 24 is provided on the second support plane 21, and the second diversion groove 24 is arranged between the third positioning protrusion 22 and the fourth positioning protrusion 23.

[0067] Among them, when the inclined surface 43 of the main prism 45 is glued to the right-angle faces 41 of the first prism 46 and the second prism 47, the cured glue will flow out under the action of extrusion at the glued surface. If the cured glue accumulates on the first abutting body 1 or the second abutting body 2, it will affect the flatness of the first support plane 11 or the second support plane 21, thereby affecting the gluing quality or increasing the cleaning time of the glued parts. Therefore, the first diversion groove 14 and the second diversion groove 24 are provided to accommodate the flowing cured glue in the grooves, so as to keep the surface flat and also facilitate the cleaning of the cured glue.

[0068] Furthermore, when the main prism 45 is placed on the first positioning protrusion 12 , the notch of the first guide groove 14 covers the inclined surface 43 of the main prism 45 ; when the main prism 45 is placed on the third positioning protrusion 22 , the notch of the second guide groove 24 covers the inclined surface 43 of the main prism 45 .

[0069] It can be understood that after the first positioning protrusion 12 supports the main prism 45, the inclined surface 43 of the main prism 45 is higher than the first positioning protrusion 12. When the first prism 46 is glued to the inclined surface 43 of the main prism 45, the second positioning protrusion 13 is higher than the inclined surface 43 of the main prism 45. Therefore, the first guide groove 14 is set between the first positioning protrusion 12 and the second positioning protrusion 13. The first guide groove 14 can cover the inclined surface 43 of the main prism 45, and the cured glue can directly enter the first guide groove 14 after flowing out. Similarly, the second guide groove 24 is set in the same way as the first guide groove 14, which will not be repeated here.

[0070] Furthermore, a support body 5 is disposed on each of the first leaning body 1 and the second leaning body 2 , and the support body 5 is used to support the first leaning body 1 and the second leaning body 2 , so that the first support plane 11 and the second support plane 21 are kept in a vertical state.

[0071] During the gluing process, the first leaning body 1 and the second leaning body 2 are in a vertical manner, that is, the first supporting plane 11 and the second supporting plane 21 are in a vertical state. In this way, when the first positioning protrusion 12 and the third positioning protrusion 22 support the main prism 45, the main prism 45 can be stably supported by the first positioning protrusion 12 and the third positioning protrusion 22 by relying on its own gravity. After the support body 5 is provided, the first leaning body 1 and the second leaning body 2 can be more stable when placed vertically, thereby improving the accuracy of the gluing process.

[0072] In some embodiments, the support body 5 is disposed on a side of the first support body 1 away from the first support plane 11. Of course, the support body 5 can also be disposed at other positions of the first support body 1 to ensure that the first support body 1 can be stably placed. Similarly, see Figure 7 The support body 5 may also be arranged on the side of the second support body 2 facing away from the second support plane 21 .

[0073] In some embodiments, the first positioning protrusion 12 and the second positioning protrusion 13 are detachably connected to the second backrest body 2 , the third positioning protrusion 22 is detachably connected to the third backrest body 3 , and the fourth positioning protrusion 23 is detachably connected to the second backrest body 2 .

[0074] The first positioning protrusion 12, the second positioning protrusion 13, the third positioning protrusion 22 and the fourth positioning protrusion 23 can be installed at different positions according to actual conditions to meet the gluing positioning requirements of right-angle prisms of different specifications.

[0075] Among them, the detachable connection methods include fixing with curing glue and optical glue fixing.
