Description

Technical Field

[0001] This utility model relates to the field of light transmittance detection technology for adhesive layers of glued prisms, and in particular to a device for detecting the light transmittance of adhesive layers of glued prisms. Background Technology

[0002] A glued prism is an optical element that tightly bonds two or more prisms together using a specific gluing technique. These prisms are glued together with a colorless, transparent optical adhesive that has a transmittance of more than 90% within a specified optical range. During the gluing process, it is necessary to ensure precise alignment between the prisms to eliminate phase shifts in reflections from the optical surfaces and to ensure the consistency of the optical path.

[0003] Working principle of the adhesive layer transmittance testing device for glued prisms: The glued prism to be tested is placed on the carrier plate and clamped by the clamp. By rotating the transmission block, the direction of the force applied by the control block to the transmission block is changed, so that the carrier plate slides out or in automatically inside the testing instrument. When the carrier plate slides into the testing instrument, the testing instrument begins to test the transmittance of the adhesive layer of the glued prism. After the test is completed, the carrier plate will automatically slide out, making it easy to remove the prism.

[0004] However, most existing gluing prism gluing transmittance testing devices use clamping components to hold the gluing prism and push it into the testing device for testing. This testing method cannot adjust the height and angle of the gluing prism, reducing the practicality of the device. Utility Model Content

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] Reference Figure 1-5This is the first embodiment of the present invention, which provides a device for detecting the transmittance of the adhesive layer of a glued prism. The device includes a detection box 3, a detection port is provided through one side of the detection box 3, and a sealing door 4 is slidably connected to both sides of the detection port to shield external light during the detection of the glued prism and avoid affecting the detection effect. The detection instrument body 1 is fixedly installed on the top of the detection box 3. The detection instrument body 1 mainly consists of a light source, a detector, a control system, a display and output device, etc.

[0029] The working principle of the main body 1 of the detector: The light source emits light of a specific wavelength. After being focused, this light shines on the adhesive layer of the adhesive prism to be tested. The detector converts the received light signal into an electrical signal. This electrical signal is proportional to the intensity of the transmitted light, so it can be used to represent the transmittance of the adhesive layer. The control system processes and analyzes the electrical signal output by the detector, calculates the transmittance value of the adhesive layer, and finally, the measurement result is displayed on the display device and can be output as a report or chart through a printer or other device for user analysis and use.

[0030] Inside the testing chamber 3 is a horizontally movable support plate 11. Two electric telescopic rods 12 are fixedly installed on the top of the support plate 11. An installation plate 14 is fixedly connected to the end of the electric telescopic rod 12 away from the support plate 11. A support plate 16 is rotatably installed on the top of the installation plate 14. Two opposing arc-shaped clamping parts 15 are on the top of the support plate 16. A speed-regulating motor 2 is fixedly installed on the outer surface of the testing chamber 3. A threaded adjusting rod 6 is fixedly connected to the output end of the speed-regulating motor 2.

[0031] A threaded moving block 8 is rotatably mounted on the outer wall of the threaded adjusting rod 6. A sliding rod 5 is fixedly connected to the inner wall of the detection box 3. A sliding block 10 is slidably connected to the outer wall of the sliding rod 5. A connecting plate 9 is fixedly connected to the side of the sliding block 10 near the threaded moving block 8. The side of the connecting plate 9 away from the sliding block 10 is fixedly connected to the side of the threaded moving block 8 near the sliding block 10. An L-shaped connector 7 is fixedly connected to the top of the connecting plate 9.

[0032] Example 2

[0033] Reference Figure 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: the side of the L-shaped connector 7 away from the connecting plate 9 is fixedly connected to the side of the bearing plate 11 near the threaded moving block 8; a servo motor 13 is fixedly installed at the bottom of the mounting plate 14; the output end of the servo motor 13 is fixedly connected to the bottom of the support plate 16; an annular groove is opened at the top of the support plate 16; a sliding column 17 is slidably connected to the inner wall of the annular groove; the sliding column 17 slides in the annular groove, which helps to improve the stability of the rotation of the support plate 16.

[0034] The end of the sliding column 17 away from the support plate 16 is fixedly connected to the bottom of the support plate 16. A double-threaded rod 19 is rotatably installed on the inner wall of the support plate 16. A knob 20 is fixedly connected to the end of the double-threaded rod 19 away from the support plate 16. A threaded adjusting seat 18 is rotatably connected to the outer wall of the double-threaded rod 19. The top of the threaded adjusting seat 18 is fixedly connected to the bottom of the arc-shaped clamping member 15. When the operator rotates the knob 20, the two threaded adjusting seats 18 move in opposite directions, and at the same time, the two arc-shaped clamping members 15 move in opposite directions to clamp the glued prism.

[0035] The remaining structure is the same as that in Example 1.

[0036] During use, the staff first opens the closed door 4 of the detection port, starts the speed regulating motor 2, drives the threaded adjusting rod 6 to rotate clockwise, drives the threaded moving block 8 to move towards the detection port, drives the sliding block 10 to move towards the detection port on the sliding rod 5, drives the connecting plate 9 to move towards the detection port, drives the L-shaped connecting piece 7 to move towards the detection port, thereby driving the arc-shaped clamping piece 15 to move towards the detection port until it moves out of the detection port.

[0037] During use, the operator turns the knob 20, which drives the double-headed threaded rod 19 to rotate, causing the two threaded adjustment seats 18 to move in opposite directions. At the same time, it drives the two arc-shaped clamping parts 15 to move in opposite directions to clamp the glued prism. Then, the speed-regulating motor 2 is started, which drives the threaded adjustment rod 6 to rotate counterclockwise, causing the threaded moving block 8 to move into the detection box 3. Then, the main body of the detector 1 is started to detect the glued prism.

[0038] During use, while the glued prism is being tested inside the testing chamber 3, the height of the mounting plate 14 and the distance between the glued prism and the main body 1 of the testing instrument can be adjusted by activating the electric telescopic rod 12. At the same time, the servo motor 13 is activated to drive the support plate 16 to rotate on the top of the mounting plate 14, which in turn drives the glued prism to rotate. This allows for testing at different positions of the glued prism, which helps to improve the accuracy of the testing.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
