Description

Technical Field

[0001] This utility model relates to the field of optical testing technology, specifically a multi-purpose optical testing device. Background Technology

[0002] Multipurpose optical testing equipment is an integrated precision instrument mainly used to measure and analyze key performance parameters of optical components and systems, such as transmittance, reflectance, refractive index, wavefront distortion, and spectral characteristics.

[0003] Multipurpose optical testing equipment is compatible with a variety of testing functions through modular design, such as interferometers, spectrophotometers, and image quality inspection. It can be widely used in the research, development, production and quality inspection of products such as lenses, filters, lasers, and displays. It features high precision and multi-scenario adaptability, which significantly improves the production efficiency and testing reliability of the optical industry.

[0004] When existing multi-purpose optical testing equipment is in operation, the lens under test is first precisely clamped in a special fixture and fixed. Then, the equipment selects an appropriate light source to illuminate the lens according to the test requirements. Next, the high-precision sensor built into the equipment captures the image or optical path information formed through the lens. Finally, the analysis software on the equipment processes this information in real time, automatically calculates and outputs the key optical performance indicators of the lens, such as focal length, MTF (modulation transfer function), distortion, field curvature, astigmatism, transmittance, and image plane illumination uniformity, to complete a comprehensive evaluation of the lens's various performance characteristics.

[0005] However, in the existing multi-purpose optical testing equipment, the lens needs to be rigidly fixed inside the fixture during testing. However, the fixture usually only supports single-dimensional planar positioning and lacks the freedom of angle adjustment. Therefore, it is impossible to dynamically adjust the pitch, yaw or rotation attitude of the lens during testing, which seriously restricts the comprehensive evaluation of the optical performance of the lens under different incident angles or installation tilt angles.

[0006] Therefore, we propose a multi-purpose optical testing device to address the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a multi-purpose optical testing device to solve the problem mentioned in the background art that the pitch, yaw or rotation attitude of the lens cannot be dynamically adjusted during testing.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A multi-purpose optical testing device includes a base plate and an optical testing device body. The optical testing device body is fixedly connected to the base plate. A lifting plate that can be raised and lowered is provided on the surface of the base plate. A lifting mechanism that drives the lifting plate to move is provided on the surface of the base plate. A flipping frame is rotatably connected inside the lifting plate. A clamping mechanism for holding test materials is provided inside the flipping frame. A rotating shaft that drives the flipping frame to flip is fixedly connected to one end of the flipping frame. An angle display mechanism that provides angle indication for the flipping frame is provided at one end of the rotating shaft. A drive frame that drives the rotating shaft to rotate is slidably connected inside the lifting plate. Several different types of light source device bodies are provided on the surface of the base plate. A switching mechanism that drives the different types of light source device bodies to switch is provided on the surface of the base plate.

[0010] The lifting mechanism includes a fixed frame fixedly connected to the surface of the base plate. A motor is fixedly connected to one end of the fixed frame. A lead screw is fixedly connected to the output shaft of the motor. The lead screw is rotatably connected inside the fixed frame and is threadedly connected to the lifting plate.

[0011] The clamping mechanism includes a limiting rod fixedly connected inside the flip frame, and a movable clamping plate is slidably connected to the surface of the limiting rod.

[0012] A spring that drives the clamping plate to move is fixedly connected to one side of the clamping plate, and the spring is sleeved on the surface of the limiting rod.

[0013] The surface of the clamping plate is provided with a limiting groove to facilitate the engagement of the test material.

[0014] The angle display mechanism includes a pointer fixedly connected to one end of the rotating shaft, a scale fixedly connected to one side of the lifting plate, and the pointer slidably connected to the surface of the scale to display the angle of rotation.

[0015] The rotating shaft has a toothed groove on its surface, and the drive frame has a drive groove inside that matches the toothed groove. The drive groove meshes with the toothed groove.

[0016] One end of the drive frame is threaded with an adjusting bolt, which is rotatably connected inside the lifting plate.

[0017] The switching mechanism includes a fixed rod fixedly connected to the surface of the base plate, a mounting plate fixedly installed on the surface of the fixed rod, a rotatable turntable plate rotatably connected to the surface of the mounting plate, a support plate fixedly connected to the surface of the turntable plate, and the surface of the support plate fixedly connected to the body of the light source device.

[0018] One end of the mounting plate is threaded with a fixing bolt, and the other end of the fixing bolt presses against the side of the turntable plate to fix it.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0020] By rotating the adjusting bolt, the adjusting bolt rotates inside the lifting plate. The adjusting bolt drives the drive frame to slide axially inside the lifting plate. At this time, the drive frame drives the drive groove to move, causing the toothed groove that meshes with the drive groove to rotate. This drives the rotating shaft to rotate, causing the rotating shaft to rotate the flipping frame inside the lifting plate for angle adjustment. Through the flipping adjustment, it is convenient to dynamically adjust the pitch, yaw, or rotation attitude of the lens during testing, which facilitates a comprehensive evaluation of the optical performance of the lens under different incident angles or installation tilt angles.

[0021] The rotating shaft is driven by the flip frame, which in turn drives the pointer to rotate on the dial surface. By observing the pointer's position on the dial surface, the angle of the flip frame can be displayed, thus improving the accuracy of lens testing.

[0022] By loosening the screws on the surface of the mounting plate, the mounting plate can slide on the surface of the fixing rod for height adjustment and easy disassembly. Loosening the fixing bolts and rotating the turntable plate causes it to rotate inside the mounting plate, which in turn drives the support plate to rotate. This allows the support plate to switch between different types of light source devices, enabling rapid switching of test light sources and making it suitable for multi-purpose optical testing.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-6 This utility model provides a technical solution:

[0032] like Figures 1-6 As shown, a multi-purpose optical testing device includes a base plate 1 and an optical testing device body 2. The optical testing device body 2 is fixedly connected to the base plate 1. A lifting plate 6 that can be raised and lowered is provided on the surface of the base plate 1. A lifting mechanism for driving the lifting plate 6 to move is provided on the surface of the base plate 1. A flipping frame 7 is rotatably connected inside the lifting plate 6. A clamping mechanism for holding the test material is provided inside the flipping frame 7. A rotating shaft 12 for driving the flipping frame 7 to flip is fixedly connected to one end of the flipping frame 7. An angle indicator for the flipping frame 7 is provided at one end of the rotating shaft 12. Angle display mechanism, inside the lifting plate 6, a drive frame 15 that drives the rotating shaft 12 to rotate is slidably connected, the surface of the base plate 1 is provided with several different types of light source device bodies 21, the surface of the base plate 1 is provided with a switching mechanism that drives the different types of light source device bodies 21 to switch, the surface of the rotating shaft 12 is provided with a toothed groove 18, the inside of the drive frame 15 is provided with a drive groove 17 that is compatible with the toothed groove 18, the drive groove 17 meshes with the toothed groove 18, one end of the drive frame 15 is threadedly connected with an adjusting bolt 16, the adjusting bolt 16 is rotatably connected inside the lifting plate 6.

[0033] like Figures 1-6 As shown, by placing the lens inside the clamping mechanism, the lens is fixed inside the flip frame 7. The lifting mechanism drives the lifting plate 6 to rise and fall, which in turn drives the flip frame 7 to rise and fall to the appropriate position. By rotating the adjusting bolt 16, the adjusting bolt 16 rotates inside the lifting plate 6. The adjusting bolt 16 drives the drive frame 15 to slide axially inside the lifting plate 6. At this time, the drive frame 15 drives the drive groove 17 to move, causing the tooth groove 18 that meshes with the drive groove 17 to rotate, driving its rotating shaft 12 to rotate. The rotating shaft 12 drives the flip frame to flip inside the lifting plate 6 for angle adjustment. At the same time, the angle display mechanism conveniently displays the flip angle. Then, the switching mechanism is activated to switch the light source body to suit different test scenarios. Finally, the optical test equipment body 2 is activated to test the lens.

[0034] Furthermore, such as Figure 1 and Figure 2As shown, the lifting mechanism includes a fixed frame 3 fixedly connected to the surface of the base plate 1. A motor 4 is fixedly connected to one end of the fixed frame 3. A lead screw 5 is fixedly connected to the output shaft of the motor 4. The lead screw 5 is rotatably connected inside the fixed frame 3 and is threadedly connected to the lifting plate 6.

[0035] The motor 4 drives the lead screw 5 to rotate, causing the lead screw 5 to rotate inside the fixed frame 3. At the same time, the lead screw 5 drives the lifting plate 6 to slide inside the fixed frame 3, thereby realizing the lifting of the lifting plate 6.

[0036] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the clamping mechanism includes a limiting rod 10 fixedly connected inside the flip frame 7. A movable clamping plate 8 is slidably connected to the surface of the limiting rod 10. A spring 11 for driving the clamping plate 8 to move is fixedly connected to one side of the clamping plate 8. The spring 11 is sleeved on the surface of the limiting rod 10. A limiting groove 9 is provided on the surface of the clamping plate 8 to facilitate the clamping of the test material.

[0037] The lens is placed inside the clamp plate 8, and the clamp plate 8 is moved by the spring 11 to slide on the surface of the limiting rod 10, so that the clamp plate 8 moves the limiting groove 9 to engage the lens and complete the fixation of the lens.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the angle display mechanism includes a pointer 14 fixedly connected to one end of the rotating shaft 12, a scale 13 fixedly connected to one side of the lifting plate 6, and the pointer 14 slidably connected to the surface of the scale 13 for displaying the angle of rotation.

[0039] The rotating shaft 12 is driven to rotate by the flipping frame, which in turn drives the pointer 14 to rotate on the surface of the dial 13. By observing the scale on the dial 13 where the pointer 14 points, the angle of the flipping frame can be displayed.

[0040] Furthermore, such as Figure 1 and Figure 6 As shown, the switching mechanism includes a fixed rod 19 fixedly connected to the surface of the base plate 1, a mounting plate 20 fixedly installed on the surface of the fixed rod 19, a rotatable turntable plate 22 rotatably connected to the surface of the mounting plate 20, a support plate 24 fixedly connected to the surface of the turntable plate 22, the surface of the support plate 24 being fixedly connected to the light source device body 21, and a fixing bolt 23 threadedly connected to one end of the mounting plate 20, the fixing bolt 23 pressing against the side of the turntable plate 22 to fix it.

[0041] By loosening the screws on the surface of the mounting plate 20, the mounting plate 20 can slide on the surface of the fixing rod 19 for height adjustment and easy disassembly. Loosening the fixing bolts 23 and rotating the turntable plate 22 causes the turntable plate 22 to rotate inside the mounting plate 20, which in turn drives the support plate 24 to rotate. This allows the support plate 24 to switch between different types of light source equipment bodies 21, enabling rapid switching of test light sources and making it suitable for multi-purpose optical testing.

[0042] The working principle of this multi-purpose optical testing equipment is as follows:

[0043] By rotating the adjusting bolt 16, the adjusting bolt 16 rotates inside the lifting plate 6. The adjusting bolt 16 drives the drive frame 15 to slide axially inside the lifting plate 6. At this time, the drive frame 15 drives the drive groove 17 to move, causing the toothed groove 18 that meshes with the drive groove 17 to rotate, driving its rotating shaft 12 to rotate. The rotating shaft 12 drives the flipping frame to flip inside the lifting plate 6 for angle adjustment. Through the flipping adjustment, the tilt, yaw or rotation attitude of the lens can be dynamically adjusted during testing, facilitating a comprehensive evaluation of the optical performance of the lens under different incident angles or installation tilt angles.

[0044] The rotating shaft 12 is driven to rotate by the flip frame, which in turn drives the pointer 14 to rotate on the surface of the dial 13. By observing the scale on the dial 13 where the pointer 14 points, the angle of the flip frame can be displayed, thus improving the accuracy of the test lens.

[0045] By loosening the screws on the surface of the mounting plate 20, the mounting plate 20 can slide on the surface of the fixing rod 19 for height adjustment and easy disassembly. Loosening the fixing bolts 23 and rotating the turntable plate 22 causes the turntable plate 22 to rotate inside the mounting plate 20, which in turn drives the support plate 24 to rotate. This allows the support plate 24 to switch between different types of light source equipment bodies 21, enabling rapid switching of test light sources and making it suitable for multi-purpose optical testing.

[0046] Although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
