Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, in particular to a detection tool for gluing a hollow prism. Background Technique

[0002] A prism is a transparent object enclosed by planes that intersect pairwise but are not parallel to each other, used for splitting light or dispersing a light beam.

[0003] There is a current hollow prism which is formed by gluing a square glass lens and a triangular glass lens. The included angle between the square glass lens and the triangular glass lens is 90°. However, due to certain thickness errors in the gluing between the lenses, the included angle between the square glass lens and the triangular glass lens is not necessarily 90°. According to the design requirements, the error range within 90°±10″ is qualified. Otherwise, if the error is large, when the hollow prism is installed and used, the optical path will deflect and the expected effect cannot be achieved. At this time, it is necessary to readjust the gluing part of the hollow prism. However, in the prior art, it is difficult to directly measure the angle after gluing the hollow prism, and it can only be measured by precise instruments, which is very inconvenient. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above problems and design a detection tool for gluing a hollow prism, which solves the problem that it is difficult to determine the gluing angle of the hollow prism.

[0005] To achieve the above object, the technical solution of the utility model is as follows: A detection tool for gluing a hollow prism, including those installed on a tooling plate:

[0006] A fixed block, on one side of which a reflecting lens is fixed, and an incident channel and a reflecting channel that communicate with each other are formed inside the fixed block;

[0007] A laser generator, which is arranged on one side of the fixed block and is directly opposite to the incident channel. The laser emitted by the laser generator enters from the incident channel and can be reflected by the reflecting lens and then exit from the reflecting channel;

[0008] A base, on which a floating platform is arranged. The floating platform is provided with a limiting member for limiting at least one side of the glued product. The glued product located on the floating platform is directly opposite to the reflecting channel;

[0009] A camera, which is arranged opposite to the glued product located on the floating platform and can receive the light reflected by the glued product.

[0010] Preferably, a first fixing seat is further provided on the tooling plate. The laser generator is horizontally installed and fixed on the side of the first fixing seat, and the first fixing seat has a through hole through which the light emitted by the laser generator passes.

[0011] Preferably, a second fixing seat is further provided on the tooling plate. The second fixing seat is located between the camera and the base. The second fixing seat has a through hole, and the through hole is directly opposite to the glued product on the floating platform. A lens is provided at the through hole.

[0012] Preferably, mounting holes are formed on both the first fixing seat and the second fixing seat. Bolts are arranged in the mounting holes, and the first fixing seat and the second fixing seat are fixed on the tooling plate through the bolts.

[0013] Preferably, a mounting hole communicating with the incident channel and the reflection channel is formed at the bottom of the fixing block. A bolt is arranged in the mounting hole, and the fixing block is fixed on the tooling plate through the bolt.

[0014] Preferably, a clearance hole communicating with the incident channel and the reflection channel is formed at the top of the fixing block. The clearance hole is located directly above the mounting hole.

[0015] Preferably, three adjusting bolts distributed in a triangular shape are provided on the limiting member. The adjusting bolts pass through the limiting member and the floating platform and are threadedly connected to the base. Three springs are arranged between the bottom of the floating platform and the base, and the three springs are respectively sleeved on the three adjusting bolts.

[0016] Compared with the prior art, the beneficial effects are as follows:

[0017] The detection tooling of the present utility model has the advantages of simple structure and high detection efficiency. The laser emitted from the laser generator will enter the fixing block through the incident channel, and after being reflected by the reflection lens, it will pass out from the reflection channel and enter the hollow prism. Since the floating platform can float up and down, the levelness of the hollow prism can be finely adjusted. Finally, the light is reflected by the hollow prism and then emitted to reach the camera. The camera displays an image according to the received light. By judging the position of the light spot in the image, the included angle between the two lenses of the hollow prism can be indirectly measured to see if it meets the requirements. The qualified hollow prism can cure the glue. In this way, the qualified rate of the product is greatly improved, and there is also a standard for gluing the hollow prism, and it can quickly judge whether the glued hollow prism meets the requirements.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figure 1 shown, a preferred embodiment of the present invention provides a hollow prism gluing detection tooling, which mainly includes components such as a tooling plate 1, a fixing block 5, a laser generator 4, a base 7, a floating platform 8, a first fixing seat 2, a second fixing seat 3 and a camera 10. Among them, the first fixing seat 2 and the second fixing seat 3 are located on both sides of the fixing block 5, and the laser generator 4 is horizontally fixed on the first fixing seat 2. There is a through hole on the first fixing seat 2, and the laser emitted by the laser generator 4 can pass through the through hole to provide light source for the entire optical path.

[0025] Refer to Figure 1 、 Figure 3 , the cross-sectional shape of the fixing block 5 is an isosceles right triangle. An incident channel 501 and a reflection channel 502 are formed inside the fixing block 5. The incident channel 501 and the reflection channel 502 are interconnected, and the included angle between them is 90°. The incident channel 501 and the emission channel respectively penetrate through two perpendicular planes of the fixing block 5. At the same time, a reflection lens 6 is pasted on another plane of the fixing block 5 (i.e., the plane where the base of the isosceles triangle is located), and there is a through hole on this plane, and the through hole is communicated with the incident channel 501 and the reflection channel 502.

[0026] The laser generator 4 faces the incident channel 501. Specifically, the center of the laser generator 4 coincides with the center of the incident channel 501. That is to say, the incident angle of the laser emitted by the laser generator 4 is 45°. The laser emitted from the laser generator 4 enters the fixed block 5 along the axis of the incident channel 501, and after being reflected by the reflecting lens 96, it exits from the axis of the reflection channel 502. The reflection angle of the light is also 45°.

[0027] Two mounting holes are provided at the bottom of the fixed block 5. These two mounting holes are respectively communicated with the incident channel 501 and the reflection channel 502. The fixed block 5 is fixed on the tooling plate 1 by tightening bolts in the mounting holes. Two relief holes 503 corresponding to the two mounting holes are provided at the top of the fixed block 5. The two relief holes 503 are also respectively communicated with the incident channel 501 and the reflection channel 502. The bolts can be conveniently tightened from top to bottom through the relief holes 503.

[0028] The base 7 faces the reflection channel 502. The floating platform 8 is installed on the base 7. A limiting member 81 with a certain included angle protrudes upward on the floating platform 8. The limiting member 81 is composed of a first limiting portion 811 and a second limiting portion 812. There is a certain included angle between the first limiting portion 811 and the second limiting portion 812.

[0029] Reference Figure 4 , the shape of the glued hollow prism is similar to an L shape. The long side of the L-shaped hollow prism is a square lens, and the short side is a triangular lens. The side of the square lens will closely abut against the first limiting portion 811, and there is a certain gap between the side of the triangular lens and the second limiting portion 812 to finely adjust the gluing position of the square lens and the triangular lens.

[0030] A total of three mounting holes are provided on the first limiting portion 811 and the second limiting portion 812. The three mounting holes are distributed according to the positions of the three vertices of a triangle. A regulating bolt 11 is provided in each mounting hole. The regulating bolt 11 passes through the limiting member 81 and the floating platform 8 and is threadedly connected to the base 7. A spring (not shown in the figure) is sleeved on each regulating bolt 11. The spring is located between the floating platform 8 and the base 7. The floating platform 8 can float left and right and up and down through the spring, and the levelness of the hollow prism located on the floating platform 8 can be adjusted by rotating the regulating bolts 11 at different positions.

[0031] After the hollow prism is placed on the floating platform 8, the square lens of the hollow prism will face the reflection channel 502 on the fixed block 5 so that the reflected light can directly reach the square lens. The reflected light will be reflected once on the surface of the square lens, reach the surface of the triangular lens, and then be reflected once by the triangular lens and emitted.

[0032] The second fixed seat 3 faces the triangular lens of the hollow prism. There is also a through hole on the second fixed seat 3, and a lens 9 is pasted at the position where the through hole is located. The lens 9 completely blocks the through hole. The function of the lens 9 is to remove stray light. The light reflected from the triangular lens of the hollow prism will directly pass through the lens 9 and exit through the through hole. The camera 10 faces the through hole on the second fixed seat 3, and the camera 10 will receive the reflected light exiting through the through hole.

[0033] The camera 10 will image the light. By judging the offset position of the light spot from the center of the image, it can then be detected whether the included angle between the triangular lens and the square lens of the hollow prism is within the range of 90°±10″. The larger the offset position of the light spot from the center of the image, the greater the possible error angle.

[0034] If the light spot is exactly at the center of the image, it means that the light incident on the hollow prism is parallel to the light finally reflected from the hollow prism, and the included angle between the triangular lens and the square lens of the hollow prism is exactly 90°.

[0035] To fix the first fixed seat 2 and the second fixed seat 3, mounting holes are provided on both the first fixed seat 2 and the second fixed seat 3. Bolts are arranged in each mounting hole, and the first fixed seat 2 and the second fixed seat 3 are both fixed on the tooling plate 1 through bolts.

[0036] As Figure 2 shown, first, glue is applied to the square lens and the triangular lens of the hollow prism and glued into the desired shape. Then, the glued hollow prism is placed on the floating platform 8 and limited by the limiting member 81. Next, the laser generator 4 emits a laser beam. After being reflected by the reflecting lens 6, the laser enters the hollow prism, and finally is reflected out of the hollow prism, passes through the lens 9, reaches the camera 10, and is imaged and displayed in the camera 10. By finely adjusting the three adjusting bolts 11 on the floating platform 8, the levelness of the hollow prism is adjusted so that the light reflected from the hollow prism can be reflected into the camera 10. Whether the angle of the hollow prism after gluing meets the requirements is judged by the position of the light spot after imaging. If it meets the requirements, the glue can be cured with an ultraviolet lamp. If it does not meet the requirements, the included angle between the two lenses of the hollow prism can be finely adjusted.

[0037] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present utility model. Some changes that those skilled in the art of this technology may make to some parts thereof all reflect the principles of the present utility model and are within the protection scope of the present utility model.
